Materials based on hydroxyapatite (HAp) Synthesized from bio-wastes have been regarded as useful, novel, eco-friendly medical applications that are targeted primarily for their antibacterial nature. In the present study, HAp was Synthesized from the fish scales of Labeo rohita using alkaline heat treatment and subsequently mixed with 1, 2 and 3 wt% of zinc (Zn) at 800 °C using calcination method to yield Zn-HAp composites. A detailed characterization of the generated composites was analysed by XRD, FT-IR, SEM, EDX and DLS methods. Further, antibacterial and biofilm inhibitory activity of the generated composites was determined using strains of Staphylococcus aureus and Escherichia coli. The confirmation of the presence of zinc, confirmed by EDAX spectra, XRD, FT-IR, SEM and DLS observations, established that HAp and Zn-HAp composites were without impurities, irregular in shape and were 848 nm sized particles. Although 1-3 wt% Zn-HAp composites showed antibacterial activity, the 3 wt% Zn-HAp composite was found suitable to kill the surrounding bacterial growth and showed potent inhibitory activity against biofilm formation.

Production of carp dominates world aquaculture. More than 1.1 million tonnes of rohu carp, Labeo rohita (Hamilton), were produced in 2010. Aeromonas hydrophila is a bacterial pathogen causing aeromoniasis in rohu, and is a major problem for carp production worldwide. There is a need to better understand the genetic mechanisms affecting resistance to this disease, and to develop tools that can be used with selective breeding to improve resistance. Here we use a 6 K SNP array to genotype 21 full-sibling families of L. rohita that were experimentally challenged intra-peritoneally with a virulent strain of A. hydrophila to scan the genome for quantitative trait loci associated with disease resistance. In all, 3193 SNPs were found to be informative and were used to create a linkage map and to scan for QTL affecting resistance to A. hydrophila. The linkage map consisted of 25 linkage groups, corresponding to the number of haploid chromosomes in L. rohita. Male and female linkage maps were similar in terms of order, coverage (1384 and 1393 cM, respectively) and average interval distances (1.32 and 1.35 cM, respectively). Forty-one percent of the SNPs were annotated with gene identity using BLAST (cut off E-score of 0.001). Twenty-one SNPs mapping to ten linkage groups showed significant associations with the traits hours of survival and dead or alive (P <0.05 after Bonferroni correction). Of the SNPs showing significant or suggestive associations with the traits, several were homologous to genes of known immune function or were in close linkage to such genes. Genes of interest included heat shock proteins (70, 60, 105 and "small heat shock proteins"), mucin (5b precursor and 2), lectin (receptor and CD22), tributyltin-binding protein, major histocompatibility loci (I and II), complement protein component c7-1, perforin 1, ubiquitin (ligase, factor e4b isoform 2 and conjugation enzyme e2 c), proteasome subunit, T-cell antigen receptor and lymphocyte specific protein

Six different types of fish patties were prepared from de-boned meat of three weight groups (250 500 g, 501-750 g, and 751-1,000 g) of an Indian major carp, Labeo rohita, using two extenders (boiled potato and corn flour). The weight of the fish and the type of the extender affected the nutritional quality of the patties. Cooking lowered the crude protein but increased the total lipid, total soluble sugars, and contents of the patties. Cooking yield increased with an increase in the weight of the fish. Similarly, the use of corn flour as the extender resulted in a higher cooking yield and higher fat retention capacity than boiled potato. The type of extender had no effect on the water-holding capacity of the patties. The weight of the fish and the extender had no significant effect on appearance, colour, flavour, taste, and the overall acceptability of the product. However, the patties prepared from 250-500 g and 501-750 g weight groups with corn flour as the extender had a significantly higher score for their texture. The total plate count suggested that the patties were safe (from microbiological point of view) up to a storage period of 80 days.

Catla catla, Labeo rohita, and Cirrhinus mrigala are important alimentary fish in India. Their reproduction (breeding) depends on season. The fish perceive external factors-stimuli and chemical signals through the olfactory system that plays the key role in the central regulation of reproduction. However, in the available literature, any electron microscopy data on organization of olfactory elements in these fish are absent. We have studied ultrastructure of the olfactory organ in male L. rohita by using scanning (SEM) and transmission electron microscopy (TEM). The olfactory organ consists of olfactory epithelium, a short nerve, and olfactory bulb. The organ has oval shape and consists of approximately 47-52 lamellae in adult fish and of 14-20 lamellae in fish at the stage of fingerling. These lamellae originate from the midline raphe. By using SEM, the presence of microvillar sensory and ciliated non-sensory cells in these lamellae is shown. By using TEM, a microvillar receptor cell is revealed, which has rough endoplasmic reticulum and Golgi apparatus towards the apical end. Basal cells are found at the base of the receptor cell; supporting cells are located adjacent to olfactory receptor neurons, while epithelial cells--in the non-sensory part of olfactory epithelium. Mast, blastema and macrophages cells are also found in the basal lamina. This work is the first publication on structural organization of olfactory system of the Indian major carp, which provides information about morphological and ultrastructural organization of olfactory system and opens new opportunities for study of chemical neuroanatomy, sensory signal processing, and nervous regulation of reproduction of the Indian major carp.

To explore the feasibility of Musa acuminata (banana) peels as a feed additive, effects of banana peel flour (BPF) on the growth and immune functions of Labeo rohita were evaluated. Diets containing five different concentrations of BPF (0% [basal diet], 1% [B1], 3% [B3], 5% [B5], and 7% [B7]) were fed to the fish (average weight: 15.3 g) for 60 days. The final weight gain and specific growth rate were higher (P < 0.05) in the B5 group. The most significant improvements in immune parameters such as lysozyme, alternative complement pathway, leukocyte phagocytic, superoxide dismutase, and catalase activities were observed in the B5 group. However, the B5 group exhibited the lowest malondialdehyde activity. IgM and glutathione peroxidise activities were significantly elevated in the treatment groups, except in B1, after only 30 days of feeding. Of the examined cytokine-related genes, IL-1β, TNF-α, and HSP70 were upregulated in the head kidney and hepatopancreas, and expressions were generally higher in the B3 and B5 groups. Moreover, B5 group challenged with Aeromonas hydrophila 60 days after feeding exhibited the highest survival rate (70%; P < 0.05). These results suggest that dietary BPF at 5% could promote growth performance and strengthen immunity in L. rohita. PMID:27294156

The evaluation of metal's toxicity in freshwater is one of the imperative areas of research and there is an emergent concern on the development of techniques for detecting toxic effects in aquatic animals. Oxidative stress biomarkers are very useful in assessing the health of aquatic life and more in depth studies are necessary to establish an exact cause effect relationship. Therefore, to study the effectiveness of this approach, a laboratory study was conducted in the fish Labeo rohita as a function of hexavalent chromium and the toxicity indices using a battery of oxidative stress biomarkers such as catalase (CAT), superoxide dismutase (SOD), and glutathione reductase (GR) in the liver, muscle, gills, and brain have been studied along with biometric parameters, behavioral changes, and Cr bioaccumulation. A significant increased HSI was observed in contrast to CF which reduced significantly. SOD, CAT, and GR activity increased significantly in all the tissues of treated fishes. The bioaccumulation of Cr was highest in liver followed by gills, muscle, and brain. This study highlights the significance of using a set of integrated biomarker and advocate to include these parameters in National Water Quality Monitoring Program in areas potentially polluted with metals to assess the health of the ecosystem.

This study aimed to isolate biosurfactant from CO2-sequestering Bacillus subtilis VSG4 and to evaluate its immunostimulatory effect in Labeo rohita fingerlings. Fish were injected intraperitoneally (i.p.) with 0.1 mL of phosphate-buffered saline (PBS) containing the water-soluble fraction of purified biosurfactant at 50 (S50), 100 (S100), 200 (S200), or 300 (S300) μg mL(-1). Fish injected with PBS served as controls. Various immunological parameters, including immune-related gene expression, were measured at 14, 21, and 28 days post administration (dpa). At 28 dpa, the fish were challenged with Aeromonas hydrophila and mortality was recorded up to 14 days. Among the immune parameters tested, lysozyme levels (36.32 ± 1.79 U mL(-1)), alternative complement pathway activity (76.26 ± 2.18 U mL(-1)), phagocytic activity (32.18 ± 0.67%), and serum bactericidal activity (73.2 ± 4.7%) were significantly higher (P < 0.05) in the S200 group at 21 dpa than in the controls. Respiratory burst activity (0.386 ± 0.008 OD630nm) was the highest in the S200 group at 28 dpa. Of the immune-related genes examined, pro-inflammatory cytokines (TNF-α and IL-1β) were significantly down-regulated in the S200 and S300 groups. Expression of anti-inflammatory cytokines (IL-10 and TGF-β) as well as IKB-α was higher (P < 0.05) in the S100‒S300 groups at 21 dpa. The expression of NF-κB p65, IKK-β, MAPKp38, and Myd88 was down-regulated in the treated groups when compared to the controls. Fish in the S200 group exhibited the highest post-challenge relative survival rate (67.88%). Collectively, these results suggest that secondary metabolite (biosurfactant) isolated from B. subtilis VSG4 at 200 μg mL(-1) can positively influence immune responses, enhance disease resistance, and stimulate immune-related gene expression in L. rohita.

Pinocembrin is a flavonoid that has been reported to exhibit various pharmacological and biological activities including antimicrobial, antioxidant, and anti-inflammatory. To explore the anti-inflammatory activity of pinocembrin in a fish cell line, we investigated its ability to regulate the inflammatory mediators elevated by lipopolysaccharide (LPS) in Labeo rohita head-kidney (HK) macrophages. HK macrophages of L. rohita were treated with LPS (1 μg mL(-1)) in the presence or absence of pinocembrin. We examined the inhibitory effect of pinocembrin on LPS-induced nitric oxide (NO) and prostaglandin E2 (PGE2) production. The inhibitory effect of pinocembrin on nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) was investigated by RT-PCR and western blot. The effect of pinocembrin on pro-inflammatory cytokines (tumour necrosis factor alpha (TNF-α) and interleukin-1β (IL-1β)) and anti-inflammatory cytokine IL-10 was investigated by ELISA and RT-PCR. The phosphorylation of three mitogen activated protein kinases (MAPKs) ERK, JNK, and p38 was analysed by western blot. Pinocembrin inhibited LPS-induced productions of NO and PGE2, and also markedly inhibited TNF-α, IL-1β, iNOS, and COX-2 production in a concentration-dependent manner. In addition, TNF-α and IL-1β mRNA expression levels decreased significantly, while IL-10 mRNA expression increased (P < 0.05) with pinocembrin pre-treatment. RT-PCR and western blot analysis showed that pinocembrin decreased both the mRNA and protein expression levels of LPS-induced iNOS and COX-2 in HK macrophages. Pinocembrin suppressed the phosphorylation of MAPK in LPS-stimulated HK macrophages. Further, pinocembrin significantly inhibited LPS-induced NF-κB transcriptional activity via the attenuation of IκBα degradation. Taken together, pinocembrin reduced the levels of pro-inflammatory mediators, such as iNOS, COX-2, TNF-α, and IL-1β, by inhibiting NF-κB activation via the suppression of ERK and p38

Psidium guajava L. is a well-known traditional medicinal plant widely used in folk medicine. To explore the anti-inflammatory activity of the flavonoid fraction of guava leaf extract (FGLE), we investigated its ability to suppress the levels of inflammatory mediators elevated by lipopolysaccharide (LPS) in Labeo rohita head-kidney (HK) macrophages. HK macrophages of L. rohita were treated with LPS in the presence or absence of the FGLE. We examined the inhibitory effect of FGLE on LPS-induced nitric oxide (NO) and prostaglandin E2 (PGE2) production. The inhibitory effect of FGLE on nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) were investigated by RT-PCR and western blot. The effect of FGLE on proinflammatory cytokines tumour necrosis factor alpha (TNF-α) or interleukin-1β (IL-1β) was also investigated by ELISA and RT-PCR. The phosphorylation of three mitogen activated protein kinases (MAPK) molecules ERK, JNK and p38 was analysed by western blot analysis. FGLE inhibited LPS-induced NO and PGE2 production. It also effectively inhibited TNF-α, IL-1β, IL-10, iNOS, and COX-2 production in a concentration-dependent manner. In addition, FGLE suppressed the mRNA expression levels of TNF-α and IL-1β in LPS-stimulated HK macrophages. RT-PCR and western blot analysis showed that FGLE decreased both the mRNA and protein expression levels of LPS-induced iNOS and COX-2 in HK macrophages. FGLE suppresses the phosphorylation of MAPK molecules in LPS-stimulated HK macrophages. FGLE also significantly inhibited LPS-induced NF-κB transcriptional activity. The molecular mechanism by which FGLE suppresses the expression of inflammatory mediators appears to involve the inhibition of NF-κB activation, through the suppression of LPS-induced IκB-α degradation. Together these results suggest that FGLE contains potential therapeutic agent(s), which regulate NF-κB activation, for the treatment of inflammatory conditions in L. rohita macrophages.

Serum immunoglobulins [Ig] of rohu [Labeo rohita] were purified by affinity chromatography using bovine serum albumin as capture ligand. The purified rohu Ig [r-Ig] had a molecular weight [MW] of 880 kDa as determined with gel filtration chromatography. The heavy chain of r-Ig had an MW of 77.8 kDa and that of light chain was 26.4 kDa in SDS-PAGE. Purified r-Ig was used for the production of two anti-rohu Ig monoclonal antibodies [D7 and H4] that belonged to subclass IgG2b and IgG1, respectively. Both the MAbs were specific to heavy chain of r-Ig as seen in Western blotting. Anti-rohu Ig MAb was used as a diagnostic reagent in ELISA and immunocytochemical assays to demonstrate its application for sero-surveillance and for immunological studies in rohu. A competitive ELISA was used to demonstrate the antigenic relatedness of r-Ig with whole serum Ig of other fish species. Cross reactivity of anti-rohu Ig MAb was observed with serum Ig of Catla catla and Cirrihinus mrigala. No reactivity to serum Ig of Ophiocephalus striatus and Clarias gariepinus was seen. Anti-rohu Ig MAb was found to be suitable for the detection of pathogen specific [Edwardsiella tarda] antibodies in serum of immunized rohu by an indirect ELISA. In flow cytometry using D7 MAb, the mean percentage [+/-SE] of Ig positive cells in spleen and blood of rohu were found to be 64.85% [+/-2.34] and 51.84% [+/-2.55] of gated lymphocytes, respectively. Similarly, D7 MAb also stained 52.84% [+/-1.30] and 10.5% of gated lymphocytes in kidney and thymus, respectively. The anti-rohu Ig MAbs also showed specific staining of Ig bearing cells in spleen sections by the indirect immunoperoxidase test.

The present study was aimed to evaluate the effect of municipal wastewater of Tung Dhab drain on morphology of scale melanophores in freshwater fish Labeo rohita (Ham.). Chronic, non-renewal toxicity tests were performed with sub lethal concentrations (17.7, 26.6 and 35.4%) of wastewater for exposure durations of 15, 30 and 60 days. Recovery experiments were also performed for duration of 60 days. The scales were removed, processed and diameters of melanophores were measured using an ocular micrometer. The results showed concentration and duration dependent changes in melanophore morphology (size and dendricity) in experimental fish as compared to control fish. The values of mean melanophore size index (MMSI) varied from 5.37 ± 0.49 (17.7%) to 12.12 ± 0.81 (35.5%) in comparison to control values of 4.32 ± 0.32 and 4.55 ± 0.29 for 15 and 60 days respectively. The recovery experiments suggested that observed dark colouration due to pigment translocation is reversible, even after chronic exposure for 60 days. Copyright © 2015 Elsevier B.V.

Apolipoprotein A-I (ApoA-I) is the most abundant and multifunctional high-density lipoprotein (HDL) having a major role in lipid transport and potent antimicrobial activity against a wide range of microbes. In this study, a complete CDS of 771 bp of Labeo rohita (rohu) ApoA-I (LrApoA-I) encoding a protein of 256 amino acids was amplified, cloned and sequenced. Tissue specific transcription analysis of LrApoA-I revealed its expression in a wide range of tissues, with a very high level of expression in liver and spleen. Ontogenic study of LrApoA-I expression showed presence of transcripts in milt and 3 h post-fertilization onwards in the larvae. The expression kinetics of LrApoA-I was studied upon infection with three different types of pathogens to elucidate its functional significance. Its expression was found to be up-regulated in the anterior kidney of L. rohita post-infection with Aeromonas hydrophila. Similarly following poly I:C (poly inosinic:cytidylic) stimulation, the transcript levels increased in both the anterior kidney and liver tissues. Significant up-regulation of LrApoA-I expression was observed in skin, mucous, liver and anterior kidney of the fish challenged with the ectoparasite Argulus siamensis. Immunomodulatory effect of recombinant LrApoA-I (rApoA-I) produced in Escherichia coli was demonstrated against A. hydrophila challenge in vivo. L. rohita administered with rApoA-I at a dose of 100 μg exhibited significantly higher protection (∼55%) upon challenge with A. hydrophila 12 h post-administration of the protein, in comparison to that observed in control group, along with higher level of expression of immune-related genes. The heightened expression of ApoA-I observed post-infection reflected its involvement in immune responses against a wide range of infections including bacterial, viral as well as parasitic pathogens. Our results also suggest the possibility of using rApoA-I as an immunostimulant, particularly rendering protection

A feeding trial of 70-days was carried out to study the haemato-immunological and stress responses of Labeo rohita fingerlings reared at two water temperatures [ambient (Amb) - 27 °C and 32 °C] fed with graded levels of gelatinized corn carbohydrate (GC). Two hundred and sixteen fingerlings were randomly distributed into six treatment groups in triplicate. Three semi-purified diets were prepared containing 30% crude protein with graded levels of GC 40%, 50% and 58%. The six treatment groups were T(1) (40% GC × Amb), T(2) (40% GC × 32 °C), T(3) (50% GC × Amb), T(4) (50% GC× 32 °C), T(5) (58% GC × Amb) and T(6) (58% GC × 32 °C). The blood glucose level was significantly (p < 0.05) lowered in groups fed with 58% GC level. Neither dietary GC levels nor temperature had a significant (p > 0.05) effect on serum cortisol and superoxide dismutase activity. Lysozyme activity was significantly higher (p < 0.05) in T(1) during pre- and post-challenge period while temperature alone had a significant (p < 0.05) effect on post-challenge Nitroblue Tetrazolium and found higher at 32 °C. A significant effect of GC levels and rearing temperature was recorded on WBC in the pre- and post-challenge period. Highest pre-challenge WBC was observed in T(4) group and in the post-challenge period T(1) group recorded maximum. Water temperature had significant effect on pre-challenge haemoglobin content, highest being at 32 °C (T(2) ). A significant (p < 0.05) effect of rearing temperature and dietary GC level on total serum protein and albumin was also observed. Highest total serum protein and albumin was recorded in T(1) and globulin in T(2) . Percentage survival after challenging with Aeromonas hydrophila was highest in T(1) followed by T(3) group and lowest in T(6) . The results obtained in the present study suggest that L. rohita fingerlings may utilize higher levels of dietary GC at higher temperature (32 °C) but may affect its immunity status. © 2010 Blackwell

The myostatin (MSTN) is a known negative growth regulator of skeletal muscle. The mutated myostatin showed a double-muscular phenotype having a positive significance for the farmed animals. Consequently, adequate information is not available in the teleosts, including farmed rohu carp, Labeo rohita. In the absence of experimental evidence, computational algorithms were utilized in predicting the impact of point mutation of rohu myostatin, especially its structural and functional relationships. The four mutations were generated at different positions (p.D76A, p.Q204P, p.C312Y, and p.D313A) of MSTN protein of rohu. The impacts of each mutant were analyzed using SIFT, I-Mutant 2.0, PANTHER, and PROVEAN, wherein two substitutions (p.D76A and p.Q204P) were predicted as deleterious. The comparative structural analysis of each mutant protein with the native was explored using 3D modeling as well as molecular-dynamic simulation techniques. The simulation showed altered dynamic behaviors concerning RMSD and RMSF, for either p.D76A or p.Q204P substitution, when compared with the native counterpart. Interestingly, incorporated two mutations imposed a significant negative impact on protein structure and stability. The present study provided the first-hand information in identifying possible amino acids, where mutations could be incorporated into MSTN gene of rohu carp including other carps for undertaking further in vivo studies.

The founder stock of a captive breeding program is prone to changes in genetic structure due to inbreeding and genetic drift. Genetic characterization of the founder population using suitable molecular markers may help monitor periodic changes in the genetic structure in future. To develop benchmark information about the genetic structure we analyzed six microsatellite loci in the Brodbank collections of rohu (Labeo rohita) originated from three major rivers-the Jamuna, the Padma and the Halda. A total of 28 alleles were detected in 90 individuals with an average of 4.6 alleles per locus. The average observed heterozygosity ranged from 0.655 to 0.705 and the expected heterozygosity ranged from 0.702 to 0.725. The mean F IS values were 0.103, 0.106 and 0.018 for the Jamuna, Padma and Halda fishes respectively. The population pair-wise F ST values ranged from 0.0057 to 0.0278. Structure analysis grouped the fishes of the three rivers into two clusters. The numbers of half-sib families were 5, 5 and 4 and the numbers of full-sib families were 12, 10 and 18 for the Halda, Jamuna and the Padma samples respectively. Bottleneck was detected in all the river samples. We recommend to collect more fish from different locations of the major rivers to broaden the genetic variability of the founder stocks of the Brood bank.

Estrogen regulates numerous developmental and physiological processes and effects are mediated mainly by estrogenic receptors (ERs), which function as ligand-regulated transcription factor. ERs can be activated by many different types endocrine disrupting chemicals (EDCs) and interfere with behaviour and reproductive potential of living organism. Estrogenic regulation of membrane associated G protein-coupled estrogen receptor, GPER activity has also been reported. Bisphenol A (BPA), a ubiquitous endocrine disruptor is present in many household products, has been linked to many adverse effect on sexual development and reproductive potential of wild life species. The present work is aimed to elucidate how an environmentally pervasive chemical BPA affects in vivo expression of a known estrogen target gene, cyp19a1b in the brain, and a known estrogenic biomarker, vitellogenin (Vg) in the whole body homogenate of 30 days post fertilization (dpf) swim-up fry of Labeo rohita. We confirm that, like estrogen, the xenoestrogen BPA exposure for 5-15 days induces strong overexpression of cyp19a1b, but not cyp19a1a mRNA in the brain and increase concentration of vitellogenin in swim-up fry. BPA also induces strong overexpression of aromatase B protein and aromatase activity in brain. Experiments using selective modulators of classical ERs and GPER argue that this induction is largely through nuclear ERs, not through GPER. Thus, BPA has the potential to elevate the levels of aromatase and thereby, levels of endogenous estrogen in developing brain. These results indicate that L. rohita swim-up fry can be used to detect environmental endocrine disruptors either using cyp19a1b gene expression or vitellogenin induction.

The myostatin (MSTN) is a known negative growth regulator of skeletal muscle. The mutated myostatin showed a double-muscular phenotype having a positive significance for the farmed animals. Consequently, adequate information is not available in the teleosts, including farmed rohu carp, Labeo rohita. In the absence of experimental evidence, computational algorithms were utilized in predicting the impact of point mutation of rohu myostatin, especially its structural and functional relationships. The four mutations were generated at different positions (p.D76A, p.Q204P, p.C312Y, and p.D313A) of MSTN protein of rohu. The impacts of each mutant were analyzed using SIFT, I-Mutant 2.0, PANTHER, and PROVEAN, wherein two substitutions (p.D76A and p.Q204P) were predicted as deleterious. The comparative structural analysis of each mutant protein with the native was explored using 3D modeling as well as molecular-dynamic simulation techniques. The simulation showed altered dynamic behaviors concerning RMSD and RMSF, for either p.D76A or p.Q204P substitution, when compared with the native counterpart. Interestingly, incorporated two mutations imposed a significant negative impact on protein structure and stability. The present study provided the first-hand information in identifying possible amino acids, where mutations could be incorporated into MSTN gene of rohu carp including other carps for undertaking further in vivo studies.

This study evaluated the effects of ginger (Zingiber officinale) as a feeding supplement on the growth, skin mucus immune parameters, and cytokine-related gene expression of Labeo rohita, and its susceptibility to Aeromonas hydrophila infection. Diets containing six different concentrations of dried ginger (0% [basal diet], 0.2% [G2], 0.4% [G4], 0.6% [G6], 0.8% [G8], and 1.0% [G10] were fed to fish (average weight: 12.3 g) for 60 days. Growth parameters were examined at 30 and 60 days post-feeding. Skin mucosal immune responses and gene expression were examined 60 days post-feeding. Results showed that growth parameters such as final weight gain (93.47 ± 1.73 g) and specific growth rate (3.41 ± 0.14) were significantly higher in G8 than in the control. Among the skin mucosal immune parameters examined, lysozyme (46.5 ± 3.8 U mg(-1)), immunoglobulin level (8.9 ± 0.4 unit-mg mL(-1)), protein level (44.3 ± 2.2 mg mL(-1)) were significantly higher in G8. However, alkaline phosphatase activity (171.6 ± 10.2 IU L(-1)) was high (P < 0.05) in the G10 group. Skin mucus of G8 exhibited significantly higher inhibition zones when tested against pathogenic bacterial strains. For cytokine-related genes, anti-oxidant genes (zinc/copper superoxide dismutase [SOD1], glutathione peroxidase [GPx], anti-inflammatory cytokines (interleukin-10 [IL-10], transforming growth factor-beta [TGF-β]), signalling molecules nuclear factor erythroid 2-related factor 2 [Nrf2], and Inhibitor protein κBα [IκB-α]) were all up-regulated in the head kidney, intestine, and hepatopancreas of fish that were fed experimental diets. In addition, expression abundance was significantly higher in most tissues in G2 and/or G10, than in the control. Conversely, expression of genes encoding pro-inflammatory cytokines (IL-1β, tumour necrosis factor-alpha [TNF-α]), signalling molecules Kelch-like-ECH-associated protein 1 (Keap1), and nuclear factor kappa B p65 (NF-κBp65) were down

Histopathological changes and alterations in the activity of certain metabolic and antioxidant enzymes were analyzed in the head skin of Labeo rohita, exposed to sublethal test concentrations of the azo dye, Eriochrome black T for 4 days, using 24 h renewal bioassay method. Hypertrophied epithelial cells, increased density of mucous goblet cells, and profuse mucous secretion at the surface were considered to protect the skin from toxic impact of the azo dye. Degenerative changes including vacuolization, shrinkage, decrease in dimension, and density of club cells with simultaneous release of their contents in the intercellular spaces were associated to plug them, preventing indiscriminate entry of foreign matter. On exposure of fish to the dye, significant decline in the activity of enzymes-alkaline phosphatase, acid phosphatase, carboxylesterase, succinate dehydrogenase, catalase, and peroxidase-was associated with the binding of dye to the enzymes. Gradual increase in the activity of lactate dehydrogenase was considered to reflect a shift from aerobic to anaerobic metabolism. On transfer of azo dye exposed fish to freshwater, skin gradually recovers and, by 8 days, density and area of mucous goblet cells, club cells, and activity of the enzymes appear similar to that of controls. Alteration in histopathology and enzyme activity could be considered beneficial tool in monitoring environmental toxicity, valuable in the sustenance of fish populations.

The present study aimed to evaluate the effects of Psidium guajava L. (guava) leaves on the growth and immune response of the fish species Labeo rohita and its susceptibility to Aeromonas hydrophila infection. Diets containing five different concentrations of guava leaves (0% [basal diet], 0.1% [G1], 0.5% [G2], 1% [G3], and 1.5% [G4]) were fed to fish (average weight: 11.1 g) for 60 days. Various growth and immune parameters were examined 60 days post-feeding. Fish were challenged with A. hydrophila at the end of the trial, and mortalities were recorded over 15 days post-infection. We found that growth parameters such as percent weight gain (657.61 ± 9.74) and specific growth rate (3.37 ± 0.021) were significantly higher in G2 group than in the control (P < 0.05). Among the immune parameters examined, lysozyme levels (79.5 ± 5.1 U mL(-1)), leukocyte phagocytic activity (52 ± 4.3%), and alternative complement pathway activity (ACP) (186.1 ± 8.3 U mL(-1)) were significantly high (P < 0.05) in G2 fed group; there was, however, no significant effect of guava leaves at any concentration on plasma IgM level. Of the cytokine-related genes examined, interleukin-1beta (IL-1β) and tumour necrosis factor-alpha (TNF-α) were up-regulated in the head-kidney, intestine, and hepatopancreas of fish fed experimental diets, and expression was significantly higher in G2 and G3 than in the control group. In contrast, gene expression of IL-10, transforming growth factor-beta (TGF-β), inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), and transcription factor nuclear factor-κB (NF-κB) were down-regulated in the treatment groups. Moreover, fish fed the G2 diet exhibited a significantly higher post-challenge survival rate (66.66%). Collectively, these results suggest that dietary supplementation with guava leaves (at 0.5% concentration) could promote growth performance and strengthen immunity of L. rohita. Guava leaves therefore represent a promising feed additive

Advanced vaccine research approaches needs to explore on biodegradable nanoparticles (NPs) based vaccine carrier that can serve as antigen delivery systems as well as immuno-stimulatory action to induce both innate and adaptive immune response in fish. Immunogenicity of PLA and PLGA NPs encapsulating outer membrane protein (Omp) antigen of Aeromonas hydrophila were evaluated through intra-peritoneal injection in fish, Labeo rohita. Antigen loaded PLA-Omp (223.5 ± 13.19 nm) and PLGA-Omp (166.4 ± 21.23 nm) NPs were prepared using double emulsion method by efficiently encapsulating the antigen reaching the encapsulation efficiency 44 ± 4.58% and 59.33 ± 5.13% respectively. Our formulated PLA Omp and PLGA-Omp NPs were in nanometer range (<500 nm) and could be successfully endocyted in the body. Despite low antigen loading in PLA-Omp, it showed considerably slower antigen release in vitro than PLGA-Omp NPs. Other physical properties like zetapotential values and poly dispersity index (PDI) confirmed the stability as well as monodisperse nature of the formulated nanoparticles. The spherical and isolated nature of PLA-Omp and PLGA-Omp NPs were revealed by SEM analysis. Upon immunization of all antigenic formulations (PLA-Omp NP, PLGA-Omp NP, FIA-Omp, PLA NP, PLGA NP, PBS as control), significant higher bacterial agglutination titre and haemolytic activity were observed in case of PLA-Omp and PLGA-Omp immunized groups than rest groups at both 21 days and 42 days. The specific antibody response was significantly increased and persisted up to 42 days of post immunization by PLA-Omp, PLGA-Omp, FIA-Omp. PLA-Omp NPs showed better immune response (higher bacterial agglutination titre, haemolytic activity, specific antibody titre, higher percent survival upon A. hydrophila challenge) than PLGA-Omp in L. rohita confirming its better efficacy. Comparable antibody response of PLA-Omp and PLGA-Omp with FIA-Omp treated groups suggested that PLA and PLGA could be replacement for

Aquaculture, as a promising food industry, is expected to meet the demand for quality food from the increasing human population. As the diet is critical for feeding farm fish, such a faster growth in the industry is destined to create stress in the fishmeal market to supply diets to the tune. In this context, here, we studied the protein content of 20 plant ingredients, including aquatic weeds, cereals, pulses and oil-cakes using micro-Kjeldahl method and evaluated in vitro digestibility of these ingredients for rohu Labeo rohita and common carp Cyprinus carpio using pH-Stat method. The protein contents of water fern, duckweed, almond oil-cake and soybean product were 20.81, 39.75, 47.78 and 57.48%, respectively. Species-specific digestibility was found for the same plant ingredient. The degree of hydrolysis for water fern, duck weed, almond oil-cake and soybean product were 14.17, 4.80, 17.30 and 3.57%, respectively for rohu and 4.58, 6.03, 12.17 and 3.35%, respectively for common carp. This study showed that incorporation of water fern and almond oil-cake in the diet of rohu, and duck weed and almond oil-cake in the diet of common carp are beneficial considering their protein content and digestibility. These are cost-effective, protein-rich feed ingredients for aquafeed.

In this article, a cleaner, greener, cheaper and environment friendly method for the generation of self assembled silver nanoparticles (Ag NPs) applying a simple irradiation technique using the aqueous extract of the fish scales (which is considered as a waste material) of Labeo rohita is described. Gelatin is considered as the major ingredient responsible for the reduction as well as stabilisation of the self assembled Ag NPs. The size and morphology of the individual Ag NPs can be tuned by controlling the various reaction parameters, such as temperature, concentration, and pH. Studies showed that on increasing concentration and pH Ag NPs size decreases, while on increasing temperature, Ag NPs size increases. The present process does not need any external reducing agent, like sodium borohydride or hydrazine or others and gelatin itself can play a dual role: a ‘reducing agent' and ‘stabilisation agent' for the formation of gelatin-Ag NPs colloidal dispersion. The synthesized Ag NPs were characterised by Ultraviolet-Visible spectroscopy (UV-Vis), Transmission electron microscopy (TEM) and Selected area electron diffraction (SAED) analyses. The synthesized Ag NPs was used to study the catalytic reduction of various aromatic nitro compounds in aqueous and three different micellar media. The hydrophobic and electrostatic interaction between the micelle and the substrate is responsible for the catalytic activity of the nanoparticles in micelle.

We investigated effects of dietary administration of stinging nettle (Urtica dioica) on growth performance, biochemical, hematological and immunological parameters in juvenile and adult Victoria Labeo (Labeo victorianus) against Aeromonas hydrophila. Fish were divided into 4 groups and fed for 4 and 16 weeks with 0%, 1%, 2% and 5% of U. dioica incorporated into the diet. Use of U. dioica in the diet resulted in improved biochemical, hematological and immunological parameters. Among the biochemical parameters; plasma cortisol, glucose, triglyceride and cholesterol decreased while total protein and albumin in fish increased with increasing dietary inclusion of U. dioica. Among the haematology parameters: red blood cell (RBC), white blood cell (WBC) counts, haematocrit (Htc), mean cell haemoglobin (MCH), mean cell haemoglobin concentration (MCHC) and netrophiles increased with increasing dietary inclusion levels of U. dioica, some depending on the fish age. Serum immunoglobulins, lysozyme activity and respiratory burst were the main immunological parameters in the adult and juvenile L. victorianus measured and they all increased with increasing herbal inclusion of U. dioica in the diet. Dietary incorporation of U. dioica at 5% showed significantly higher relative percentage survival (up to 95%) against A. hydrophila. The current results demonstrate that using U. dioica can stimulate fish immunity and make L. victorianus more resistant to bacterial infection (A. hydrophila). Copyright © 2015 Elsevier Ltd.

Rohu is a leading candidate species for freshwater aquaculture in South-East Asia. Unlike common carp the monsoon breeding habit of rohu restricts its seed production beyond season indicating strong genetic control over spawning. Genetic information is limited in this regard. The problem is exacerbated by the lack of genomic-resources. We identified 182 reproduction-related genes previously by Sanger-sequencing which were less to address the issue of seasonal spawning behaviour of this important carp. Therefore, the present work was taken up to generate transcriptome profile by mRNAseq. 16GB, 72bp paired end (PE) data was generated from the pooled-RNA of twelve-tissues from pre-spawning rohu using IlluminaGA-II-platform. There were 64.97 million high-quality reads producing 62,283 contigs and 88,612 numbers of transcripts using velvet and oases programs, respectively. Gene ontology annotation identified 940 reproduction-related genes consisting of 184 mainly associated with reproduction, 223 related to hormone-activity and receptor-binding, 178 receptor-activity and 355 embryonic-development related-proteins. The important reproduction-relevant pathways found in KEGG analysis were GnRH-signaling, oocyte-meiosis, steroid-biosynthesis, steroid-hormone biosynthesis, progesterone-mediated oocyte-maturation, retinol-metabolism, neuroactive-ligand-receptor interaction, neurotrophin-signaling and photo-transduction. Twenty nine simple sequence repeat containing sequences were also found out of which 12 repeat loci were polymorphic with mean expected-&-observed heterozygosity of 0.471 and 0.983 respectively. Quantitative RT-PCR analyses of 13-known and 6-unknown transcripts revealed differences in expression level between preparatory and post-spawning phase. These transcriptomic sequences have significantly increased the genetic-&-genomic resources for reproduction-research in Labeo rohita. PMID:26148098

The 5' region of the mitochondrial DNA gene cytochrome c oxidase subunit I (COI) is the standard marker for DNA barcoding. However, 16 S rRNA has also been advocated for DNA barcoding in many animal species. Herein, we directly compare the usefulness of COI and 16 S rRNA in discriminating six cultivable carp species: Labeo rohita, Catla catla, Cirrhinus mrigala, Labeo fimbriatus, Labeo bata and Cirrhinus reba from India. Analysis of partial sequences of these two gene fragments from 171 individuals indicated close genetic relationship between Catla catla and Labeo rohita. The results of the present study indicated COI to be more useful than 16 S rRNA for DNA barcoding of Indian carps.

Probiotics play an important role in growth increment, immune enhancement and stress mitigation in fish. Increasing temperature is a major concern in present aquaculture practices as it markedly deteriorates the health condition and reduces the growth in fish. In order to explore the possibilities of using probiotics as a counter measure for temperature associated problems, a 30 days feeding trial was conducted to study the hemato-immunological and apoptosis response of Labeo rohita (8.3±0.4 g) reared at different water temperatures, fed with or without dietary supplementation of a probiotic mixture (PM) consisting of Bacillus subtilis, Lactococcus lactis and Saccharomyces cerevisiae) (1011 cfu kg−1). Three hundred and sixty fish were randomly distributed into eight treatment groups in triplicates, namely, T1(28°C+BF(Basal feed)+PM), T2(31°C+BF+PM), T3(34°C+BF+PM), T4(37°C+BF+PM), T5(28°C+BF), T6(31°C+BF), T7(34°C+BF) and T8(37°C+BF). A significant increase (P<0.01) in weight gain percentage was observed in the probiotic fed fish even when reared at higher water temperature (34–37°C). Respiratory burst assay, blood glucose, erythrocyte count, total serum protein, albumin, alkaline phosphatase and acid phosphatase were significantly higher (P<0.01) in the probiotic fed groups compared to the non-probiotic fed groups. A significant (P<0.01) effect of rearing temperature and dietary probiotic mixture on serum myeloperoxidase activity, HSP70 level and immunoglobulin production was observed. Degree of apoptosis in different tissues was also significantly reduced in probiotic-supplemented groups. Hence, the present results show that a dietary PM could be beneficial in enhancing the immune status of the fish and also help in combating the stress caused to the organism by higher rearing water temperature.

A 2 × 2 × 2 factorial experiment was conducted to delineate the main effect of water soaking of plant ingredients, phytase, cellulase, and their interactions on the growth and digestive enzyme activities of Labeo rohita fingerlings. Two basal diets were prepared using water-soaked (S) or unsoaked (US) plant-based ingredients. Feed of US ingredients was supplemented with phytase (U kg(-1)) and cellulase (%) at the level of 0, 0 (C(us)); 500, 0 (T(1)); 0, 0.2 (T(2)); 500, 0.2 (T(3)), and feed of S ingredients at 0, 0 (C(s)); 500, 0 (T(4)); 0, 0.2 (T(5)), and 500, 0.2 (T(6)), respectively. Three hundred and sixty fingerlings were randomly distributed into eight treatments, each with three replicates. Soaking of the ingredients for 24 h significantly reduced the tannin content. However, feeding of S diets did not improve the fish growth. Highest performance was recorded in the T(3) group. A significant interaction between dietary phytase and cellulase was observed for apparent net protein utilization. Tissue crude protein, ether extract, and ash content of the fingerlings were observed highest in the T(3) group. Activities of amylase, protease, and lipase were recorded highest in the T(3) group. Results suggested that soaking of plant-based ingredients reduces tannin content; however, growth and digestive enzyme activities of group fed soaked diet were not improved, possibly due to leaching of soluble nutrients. Probably, a shorter duration soaking may be effective in reducing tannin content and avoiding nutrients leaching.

Cirrhinus mrigala, Labeo rohita, and Catla catla are economically important fish for human consumption in Pakistan, but industrial and sewage pollution has drastically reduced their population in the River Chenab. Statistics are an important tool to analyze and interpret comet assay results. The specific aims of the study were to determine the DNA damage in Cirrhinus mrigala, Labeo rohita, and Catla catla due to chemical pollution and to assess the validity of statistical analyses to determine the viability of the comet assay for a possible use with these freshwater fish species as a good indicator of pollution load and habitat degradation. Comet assay results indicated a significant (P < 0.05) degree of DNA fragmentation in Cirrhinus mrigala followed by Labeo rohita and Catla catla in respect to comet head diameter, comet tail length, and % DNA damage. Regression analysis and correlation matrices conducted among the parameters of the comet assay affirmed the precision and the legitimacy of the results. The present study, therefore, strongly recommends that genotoxicological studies conduct appropriate analysis of the various components of comet assays to offer better interpretation of the assay data.

The physicochemical and biological properties of metals change as the particles are reduced to nanoscale. This ability increases the application of nanoparticles in commercial and medical industry. Keeping in view this importance, Silver nanoparticles (Ag-NPs) were synthesized by reduction methods using formaldehyde as reducing agent in the chemical route and lemon extracts in the biological route. The scanning electron microscope (SEM) images of nanoparticles suggested that the particles were either agglomerated or spherical in shape with mean diameter of 16.59 nm in the chemical route and 42.93 nm in the biological route. The particles were between 5 and 80 nm with maximum frequency between 5 and 20 nm in the chemical route and between 5 and 100 nm with maximum frequency between 15 and 50 nm in the biological method. In the second phase of the study, the effect of Ag-NPs on the oxidative stress was studied. For this purpose, Labeo rohita (20 ± 2.5 g in weight and 12 ± 1.4 cm in length) were involved. Six treatments were applied in three replicates having five fishes in each replicate. The first treatment was used as control group, and the other five treatments were exposed to either 10 or 20 or 30 or 45 or 55 mg L -1 of Ag-NPs for 28 days. The treatment of Ag-NPs caused oxidative stress in the liver and gill tissues, which induced alterations in the activities of antioxidant enzymes. The level of catalase (CAT) was decreased in response to Ag-NPs concentration in dose-dependent manner. Ag-NPs treatment stimulated the liver and gill tissues to significantly increase the level of superoxide dismutase (SOD), which might be due to synthesis of SOD and addition in the pre-existing SOD level. The level decreases again due to depletion of SOD level. There was a sharp decline in the activities of glutathione S-transferase (GST) in both gills and liver tissues even at lower concentration, and this decrease in the GST activity was significantly

Nucleotide-binding and oligomerization domain (NOD)-2 is a cytoplasmic pattern recognition receptor (PRR) and is a member of NOD like receptor (NLR) family. It senses a wide range of bacteria and viruses or their products and is involved in innate immune responses. In this report, NOD-2 gene was cloned and characterized from rohu (Labeo rohita) which is highly commercially important fish species in the Indian subcontinent. The full length rohu NOD-2 (rNOD-2) cDNA comprised of 3176 bp with a single open reading frame (ORF) of 2949 bp encoding a polypeptide of 982 amino acids (aa) with an estimated molecular mass of 109.65 kDa. The rNOD-2 comprised two N-terminal CARD domains (at 4-91 aa and 111-200 aa), one NACHT domain (at 271-441 aa) and seven C-terminal leucine rich repeat (LRR) regions. Phylogenetically, rNOD-2 was closely related to grass carp NOD-2 (gcNOD2) and exhibited significant similarity (94.2%) and identity (88.6%) in their amino acids. Ontogeny analysis of rNOD-2 showed its constitutive expression across the developmental stages, and highlighted the embryonic innate defense system in fish. Tissue specific analysis of rNOD-2 by quantitative real-time PCR (qRT-PCR) revealed its wide distribution; highest expression was in liver followed by blood. In response to PGN and LTA stimulation, Aeromonas hydrophila and Edwardsiella tarda infection, and poly I:C treatment, expression of rNOD-2 and its associated downstream molecules RICK and IFN-γ were significantly enhanced in the treated fish compared to control. These findings suggested the key role of NOD-2 in augmenting innate immunity in fish in response to bacterial and viral infection. This study may be helpful for the development of preventive measures against infectious diseases in fish. Copyright © 2011 Elsevier Ltd. All rights reserved.

Indigenous South African Labeo spp. show promise with regard to development of semi-intensive aquaculture, yet little research on their monogenean fauna has been conducted. Ecological aspects of monogenean fauna of the moggel Labeo umbratus (Smith 1841) and the Orange River mudfish Labeo capensis (Smith 1841), as recorded during both winter and summer sampling surveys, are reported here. Fish were collected using gill nets, euthanized and gills removed and examined to both quantify parasite numbers and distribution on the gills. Results obtained support the hypothesis that gill site preference is not due to active choice for a particular attachment site, but rather a result of water flow over gills during respiration in conjunction with fish behaviour and habitat use. Interaction between individual elements investigated (temperature effects, parasite population dynamics and host population dynamics) may be largely responsible for seasonal differences in infection statistics of monogenean parasites. Such interactions should be investigated in future large scale ecological studies, in combination with experimental studies, to further elucidate these effects.

The objective of the present study was to investigate trace metal levels of different varieties of fresh water fish using Inductively Coupled Plasma Mass Spectrophotometer after microwave digestion (MD-ICPMS). Fish samples were collected from the outlets of twin cities of Hyderabad and Secunderabad. The trace metal content in different varieties of analyzed fish were ranged from 0.24 to 1.68 mg/kg for Chromium in Cyprinus carpio and Masto symbollon, 0.20 to 7.52 mg/kg for Manganese in Labeo rohita and Masto symbollon, 0.006 to 0.07 mg/kg for Cobalt in Rastrelliger kanagurta and Pampus argenteus, 0.31 to 2.24 mg/kg for Copper in Labeo rohita and Penaeus monodon, 3.25 to 14.56 mg/kg for Zinc in Cyprinus carpio and Macrobrachium rosenbergii, and 0.01 to 2.05 mg/kg for Selenium in Rastrelliger kanagurta and Pampus argenteus, respectively. Proximate composition data for the different fishes were also tabulated. Since the available data for different trace elements for fish is scanty, here an effort is made to present a precise data for the same as estimated on ICP-MS. Results were in accordance with recommended daily intake allowance by WHO/FAO. PMID:24744789

Labeo rosae, a species with a native range in Southern Africa, was discovered in the Congo basin by re-identification of two museum specimens previously identified as Labeo mesops. The occurrence of this species in the upper Congo implies a range extension of the species of more than 1000 km. Although the species' distribution is mirrored by that of some other Cypriniformes, its occurrence in the Congo might be due to introduction by humans. © 2014 The Fisheries Society of the British Isles.

Both Hemibarbus labeo and H. medius (Cypriniformes: Cyprinidae: Gobioninae) are primary freshwater fishes and are widely distributed. As such, they provide an ideal model for phylogeographical studies. However, the similarity in morphological characters between these two species made the description of their distributions and the validation of species quite challenging. Here we employed variations in the DNA sequences of mitochondrial COI and ND5 genes (2151 bp) to solve this challenge and to study the population genetics structure of these two species. Among the 130 specimens belonging to 8 populations of H. labeo and 9 populations of H. medius from 17 drainage systems in southern China,196 variable sites (9.1% in the full sequences) falling into 50 haplotypes were identified. The haplotype diversity (h) and the nucleotide diversity (π) were 0.964 and 0.019, respectively, indicating a high level of genetic diversity and an evolutionary potential in both species. The result of neighbor-joining tree based on composite nucleotide sequences of the mtDNA COI and ND5 genes showed that the H. labeo and H. medius fell into two major clades (clade1and clade2): clade1was composed of some specimens of Oujiang River, all the specimens of Hanjiang River and Jiulongjiang River, whereas all remaining populations fell in clade2. The genetic distance between clade I and clade II was 0.036, while that between H. labeo and H. medius was 0.027. The haplotype network analyses indicated that the populations of Hanjiang River and Jiulongjiang River had relatively high genetic variation with the rest rivers. The po-pulations of Hainan Island migrated northward to Moyangjaing River. Haplotypes of the rivers of Hainan Island and Moyangjang River had relatively higher genetic variation with the Yangtze River than Pearl River. The populations of Xiangjiang River had no genetic variation with the populations of Guijiang River and Liujiang River. Analysis of molecular variance (AMOVA

Fish-borne zoonotic trematodes (FZT) are a food safety and health concern in Vietnam. Humans and other final hosts acquire these parasites from eating raw or under-cooked fish with FZT metacercariae. Fish raised in ponds are exposed to cercariae shed by snail hosts that are common in fish farm ponds. Previous risk assessment on FZT transmission in the Red River Delta of Vietnam identified carp nursery ponds as major sites of transmission. In this study, we analyzed the association between snail population density and heterophyid trematode infection in snails with the rate of FZT transmission to juvenile fish raised in carp nurseries. Snail population density and prevalence of trematode (Heterophyidae) infections were determined in 48 carp nurseries producing Rohu juveniles, (Labeo rohita) in the Red River Delta area. Fish samples were examined at 3, 6 and 9 weeks after the juvenile fish were introduced into the ponds. There was a significant positive correlation between prevalence of FZT metacercariae in juvenile fish and density of infected snails. Thus, the odds of infection in juvenile fish were 4.36 and 11.32 times higher for ponds with medium and high density of snails, respectively, compared to ponds where no infected snails were found. Further, the intensity of fish FZT infections increased with the density of infected snails. Interestingly, however, some ponds with no or few infected snails were collected also had high prevalence and intensity of FZT in juvenile fish. This may be due to immigration of cercariae into the pond from external water sources. The total number and density of potential host snails and density of host snails infected with heterophyid trematodes in the aquaculture pond is a useful predictor for infections in juvenile fish, although infection levels in juvenile fish can occur despite low density or absence infected snails. This suggests that intervention programs to control FZT infection of fish should include not only intra

The presence of cholinesterase (ChE) activity in skin mucus of three carps, Cirrhinus mrigala, Labeo rohita, and Catla catla and its applicability as biomarker of the organophosphorus insecticide exposure were investigated. Biochemical characterization, using specific substrates and inhibitors, indicated that measured esterase activity in skin mucus was mainly owing to ChEs. Significant difference in the proportion of acetylcholinesterase and butyrylcholinesterase activities was observed in skin mucus of three carps. Enzyme kinetic analysis, using the substrate acetylthiocholine iodide revealed significantly high Vmax value in C. catla compared to that in L. rohita and C. mrigala. In contrast, Vmax value using the substrate butyrylthiocholine iodide was significantly high in C. mrigala than in L. rohita and C. catla. In vitro treatment of skin mucus of three carps, with the organophosphorus insecticide Nuvan®, showed strong inhibition of ChE activities. In vivo experiments conducted using C. mrigala and exposing the fish to the sublethal test concentrations (5 and 15 mg/L) of the insecticide also revealed significant inhibition of ChE activity in mucus. In C. mrigala, exposed to the sublethal test concentrations of the insecticide for 4 days and then kept for recovery for 16 days, mucus ChE activity recovered to the control level. Thus, ChE activity in skin mucus could be considered a good biomarker of the organophosphorus insecticide exposure to fish and a useful tool in monitoring environmental toxicity.

In the present study, the complete mitochondrial genome sequence of Labeo gonius is reported using PGM sequencer (Ion Torrent). The complete mitogenome of L. gonius is obtained by the de novo sequences assembly of genomic reads using the Torrent Mapping Alignment Program (TMAP) which is 16 614 bp in length. The mitogenome of L. gonius comprised of 13 protein-coding genes, 22 tRNAs, 2 rRNA genes, and D-loop as control region along with gene order and organization, being similar to most of other fish mitogenomes of NCBI databases. The mitogenome in the present study has 99% similarity to the complete mitogenome sequence of Labeo fimbriatus, as reported earlier. The phylogenetic analysis of Cypriniformes depicted that their mitogenomes are closely related to each other. The complete mitogenome sequence of L. gonius would be helpful in understanding the population genetics, phylogenetics, and evolution of Indian Carps.

Aquatic weeds are one of the major unconventional feed ingredients tested for aquafeed formulation. Tannin content in the water lettuce, Pistia, has been quantified (26.67 mg g(-1); dry weight) and graded levels of which (12.5-200 μg) have been incorporated in the reaction mixtures to evaluate any change in the in vitro activity of the principal digestive enzymes from the three Indian major carps (IMC), namely rohu (Labeo rohita), catla (Catla catla) and mrigala (Cirrhinus mrigala). Result of the experiment revealed that the Pistia tannin (PT) significantly inhibit/lower the activities of the digestive enzymes from three IMCs in a dose-dependent manner, even at very low concentration. Significant variation in the reduction of the enzyme activities was noticed between the three fish species, as well as between the three enzymes studied. Among the three species studied, digestive enzymes from L. rohita were found to be the most sensitive to the PT, whereas enzymes from C. catla were found to be comparatively least affected. On the other hand, protease and lipase activities were comparatively more affected than the amylase activity. The results of the study suggest that more stress should be given on the elimination of tannin while incorporating feed ingredients of plant origin in fish diets.

The present study was aimed to isolate myxozoan parasites infecting the native carp Schizothorax esocinus (Heckel) and pond reared carp Labeo rohita (Ham.) collected from fresh water ecosystems of Jammu and Kashmir from July 2013 to June 2014. Various organs such as eyes, gills, scales, fins, intestines, visceral organs and pericardial cavity of as many as 100 live specimens were examined. Results revealed that 14% of the examined L. rohita were infected with Myxobolus rocatlae (Ham.) and 6% of S. esocinus (Heckel) were infected with M. kashmirensis sp. nov. Clinical signs revealed mucous laden gills while the parasitological observation under stereozoom binocular microscope revealed multiple minute plasmodia on the gills. On rupturing these plasmodia with sharp needle 100-500 myxospores were liberated. The identification to species level was done on the basis of morphological and morphometric attributes of the myxospores. This is the first record of myxozoan parasites in fishes from the state of Jammu and Kashmir, India. Histological observations of infected gills revealed plasmodia of two types (LV 4 intralamellar vascular type) in M. rocatlae and (LV 3 intralamellar vascular type) in M. kasmirensis causing necrosis, hyperplasia, hypertrophy and vacuolization of the epithelial and vascular endothelium.

The purified fish visceral protease enzyme was immobilized by using various concentrations of sodium alginate and calcium chloride to optimize the best concentration for the formation of the beads. Then it was characterized by assaying the optimal pH, temperature, storage stability and reusability. The results on immobilization with sodium alginate and calcium chloride showed that a combination of 2% sodium alginate and 0.3 M calcium chloride weas found to be the optimum concentration for the formation of spherical and stable beads, this gave a maximal entrapped activity of 48.31%, and there was no change in the optimum pH 8.0 and temperature 40°C of protease before and after entrapment. The results on stability and reusability indicated that it was stable at 4°C retaining 100% residual activity after 5 days of storage and 67% loss of activity after ten days of storage and it retained 100% residual activity on the first reuse, 75% residual activity on the second reuse, 25% residual activity on the third use and complete loss in the activity on the fourth reuse.

Because little is known about the function of Sox2 (Sry-related box-2) in teleosts, the objective of this study was to clone and characterize Sox2 complementary DNA (cDNA) from the testis of Indian major carp, Labeo rohita (rohu). The full-length cDNA contained an open reading frame of 936 nucleotides bearing the typical structural features. Phylogenetically, Sox2 of L rohita was most closely related to freshwater counterparts than marine water. The sequence information of cDNA and genomic DNA together revealed that the Sox2 gene is encoded by an uninterrupted exon. Furthermore, comparative mRNA expression profile in various organs including proliferating spermatogonial stem cells (SSCs) suggested about the participatory role of Sox2 during fish male germ cell development and maintenance of stem cells. In support, we have also provided evidence that Sox2 protein is indeed present in rohu SSCs by Western blot analysis. The evolutionarily conserved high-mobility group box domain indicated its possible involvement in common networking pathways for stem cell maintenance and pluripotency between mammals and nonmammals. Our findings could be the first step toward the use of Sox2 as a potential biomarker for proliferating SSCs and understanding the transcriptional regulatory network involved during male germ cell development and maintenance in fish species.

Post-harvest loss of catla (Catla catla), rohu (Labeo rohita), mrigal (Cirrhinus mrigala), silver carp (Hypophthalmichthys molitrix), grass carp (Ctenopharyngodon idella) and sarpunti (Puntius sarana) in a single distribution chain from harvest in Mymensingh to retail sale Rangpur town were determined, in order to obtain information on quality deterioration and existing handling and icing conditions so that suggestions for improving such practices can be made. Quality defect points of the fish at different steps of distribution channels were determined using a sensory based quality assessment tool. Percent quality loss of fish at each step of distribution was calculated from the number of cases that crossed sensory quality cut-off points. Neither of the fish lost their quality when they were in the farm gate, during transportation and in wholesale markets in Rangpur but most of the fishes lost their quality at the retail fish shops. The quality loss was 8, 12, 8, 6, 10 and 14% in case of C. catla, C. mrigala, L. rohita, H. molitrix, C. idella and P. sarana respectively in the retail markets. Fishes were not properly handled, bamboo baskets wrapped with polythene sheet were used as carrying container and inadequate ice was used during transportation. Retailers were found to be more proactive in the use of ice. However, most of the fishes were deteriorated during retail sale. The losses of farmed fishes could be minimized by adopting good handling practices like using insulated container and adequate icing.

Heavy metals are known to cause deleterious effects on human health through food chain. Human health risks were evaluated from consumption of heavy metal contaminated fish from Buriganga River in Bangladesh. Whole body of five fish species ( Puntius ticto, Puntius sophore, Puntius chola, Labeo rohita and Glossogobius giuris ) were analyzed which contained various concentrations of Cd, As, Pb, Cr, Ni, Zn, Se, Cu, Mo, Mn, Sb, Ba, V and Ag. Concentrations of Mn, Zn, Se and Pb in all fish species were above the Food Safety Guideline (FSG) by WHO/FAO. Assessment of noncarcinogenic health hazard by target hazard quotient (THQ) indicated no concern from consumption of these fish except for Mn. However, all metals together may affect human health as revealed by hazard index (HI). The target cancer risk (TR) values suggested carcinogenic risk from Ni and As. Taken together it can be concluded that there is potential human health risk in consuming fish from river Buriganga.

This investigation is aimed to study an impact of habitat degradation on proximate composition and amino acid (AAs) profile of Catla catla, Labeo rohita and Cirrhinus mrigala collected from polluted, non-polluted area (upstream) and a commercial fish farm. The amino acid profile was estimated by the amino acid analyzer. C. catla collected from the polluted environment had highest lipid, protein and ash contents (12.04 ± 0.01, 13.45 ± 0.01 and 0.93 ± 0.03%, respectively). The high protein content (14.73 ± 0.01 and 14.12 ± 0. 01%) was recorded in C. catla procured from non-polluted (upstream) wild habitat of River Chenab and controlled commercial fish farm. Farmed fish species showed comparatively higher moisture contents followed by upstream and polluted area fishes. C. mrigala showed significant differences in amino acid and proximate composition collected from a polluted site of the river Chenab. C. catla collected from non-polluted site of the river showed an excellent nutrient profile, followed by L. rohita (wild and farmed) and C. mrigala (polluted area), respectively. All fishes from the polluted areas of the River Chenab indicated a significant decrease in the concentration of some AAs when compared to farmed and wild (upstream) major carps. Omitting of some important AAs was also observed in the meat of fish harvested from polluted habitat of this river. C. mrigala and L. rohita exhibited a significant increase in the concentration of some of non-essential amino acids such as cysteine in their meat. The results indicated that wild fish (upstream) and farmed fish species had highest protein contents and amino acid profile and hence appeared to be the best for human consumption. The proximate composition and AAs profiles of fish harvested from the polluted area of the river clearly indicated that efforts shall be made for the restoration of habitat to continue the requirement of high quality fish meat at a low cost to the human

Juveniles in court.

PubMed

Soulier, Matthew F; Scott, Charles L

2010-01-01

Nineteenth-century American reformers were concerned about the influence of immaturity and development in juvenile offenses. They responded to their delinquent youths through the creation of juvenile courts. This early American juvenile justice system sought to treat children as different from adults and to rehabilitate wayward youths through the state's assumption of a parental role. Although these rehabilitative goals were never fully realized, the field of American child psychiatry was spawned from these efforts on behalf of delinquent youths. Early child psychiatrists began by caring for juvenile offenders. The function of a child psychiatrist with juvenile delinquents expanded beyond strictly rehabilitation, however, as juvenile courts evolved to resemble criminal adult courts-due to landmark Supreme Court decisions and also juvenile legislation between 1966 and 1975. In response to dramatically increased juvenile violence and delinquency rates in the 1980s, juvenile justice became more retributional, and society was forced to confront issues such as capital punishment for juveniles, their transfer to adult courts, and their competency to stand trial. In the modern juvenile court, child psychiatrists are often asked to participate in the consideration of such issues because of their expertise in development. In that context we review the role of psychiatrists in assisting juvenile courts.

Concentrations of five heavy metals (Pb, Cd, Cr, As and Hg) in eight highly consumed cultured fish species ( Labeo rohita, Clarias gariepinus, Hypophthalmichthys molitrix, Cyprinus capio, Puntius sarana, Oreochromis mossambicus, Pangasius pangasius and Anabas testudineus ) collected from four wholesale markets of Dhaka city, Bangladesh (Karwan Bazar, Mohammadpur Town Hall, Newmarket and Mirpur-1) were measured using atomic absorption spectrometry (AAS) in order to evaluate the potential human health risks from the consumption of fish. The estimated daily intake (EDI) of all the studied heavy metals calculated on the basis of mean fish consumption of 49.5 g person -1 d -1 by Bangladeshi households indicated that no risk to people's health with respect to the EDI of investigated heavy metals through the consumption of the fish samples. From the human health point of view, the estimation of non-carcinogenic risk indicated that intake of individual heavy metal through the consumption of fish was safe for human health, whereas, consumption of combined heavy metals suggested potential health risk to highly exposed consumers. However, the estimation of carcinogenic risk of arsenic due to the consumption of fish indicated that consumers remain at risk of cancer.

Are antipredator behaviours of hatchery Salmo salar juveniles similar to wild juveniles?

PubMed

Salvanes, A G V

2017-05-01

This study explores how antipredator behaviour of juvenile Atlantic salmon Salmo salar developed during conventional hatchery rearing of eggs from wild brood stock, compared with the behaviour of wild-caught juveniles from the same population. Juveniles aged 1+ years were tested in two unfamiliar environments; in one S. salar were presented with simulated predator attacks and in the other they were given the opportunity to explore an open-field arena. No difference was found in their spontaneous escape responses or ventilation rate (reflex responses) after simulated predator attacks. Hatchery-reared juveniles were more risk-prone in their behaviours than wild-caught individuals. Hatchery juveniles stayed less time in association with shelter. In the open-field arena, hatchery juveniles were more active than wild juveniles. Hatchery juveniles were also immobile for less time and spent a shorter amount of time than wild juveniles in the fringe of the open-field arena. Salmo salar size had no effect on the observed behaviour. Overall, this study provides empirical evidence that one generation of hatchery rearing does not change reflex responses associated with threats, whereas antipredator behaviour, typically associated with prior experience, was less developed in hatchery-reared than in wild individuals. © 2017 The Fisheries Society of the British Isles.

Mitchell, Kimberly J; Finkelhor, David; Wolak, Janis

2010-02-01

Two studies were conducted to identify the incidence (Study 1) and characteristics (Study 2) of juvenile prostitution cases known to law enforcement agencies in the United States. Study 1 revealed a national estimate of 1,450 arrests or detentions (95% confidence interval [CI]: 1,287-1,614) in cases involving juvenile prostitution during a 1-year period. In Study 2, exploratory data were collected from a subsample of 138 cases from police records in 2005. The cases are broadly categorized into three main types: (a) third-party exploiters, (b) solo prostitution, and (c) conventional child sexual abuse (CSA) with payment. Cases were classified into three initial categories based on police orientation toward the juvenile: (a) juveniles as victims (53%), (b) juveniles as delinquents (31%), and (c) juvenile as both victims and delinquents (16%). When examining the status of the juveniles by case type, the authors found that all the juveniles in CSA with payment cases were treated as victims, 66% in third-party exploiters cases, and 11% in solo cases. Findings indicate law enforcement responses to juvenile prostitution are influential in determining whether such youth are viewed as victims of commercial sexual exploitation or as delinquents.

Use of black carp (Mylopharyngodon piceus) in biological control of intermediate host snails of fish-borne zoonotic trematodes in nursery ponds in the Red River Delta, Vietnam

PubMed Central

2013-01-01

Background The risks of fish-borne zoonotic trematodes (FZT) to human health constitute an important problem in Vietnam. The infection of humans with these trematodes, such as small liver trematodes (Clonorchis sinensis and Opisthorchis viverrini), intestinal trematodes (Heterophyidae) and others is often thought to be linked to fish culture in areas where the habit of eating raw fish is common. Juvenile fish produced in nurseries are often heavily infected with FZT and since fishes are sold to aquaculture facilities for growth, control of FZT in these fishes should be given priority. Controlling the first intermediate host (i.e., freshwater gastropods), would be an attractive approach, if feasible. The black carp, Mylopharyngodon piceus, is a well-known predator of freshwater snails and is already used successfully for biological control of snails in various parts of the world including Vietnam. Here we report the first trials using it for biological control of intermediate host snails in nursery ponds stocked with 1-week old fry (10–12 mm in length) of Indian carp, Labeo rohita. Methods Semi-field and field experiments were set up to test the effect of black carp on snail populations. In the semi-field experiment a known quantity of snails was initially introduced into a pond which was subsequently stocked with black carp. In the field trial in nursery ponds, density of snails was estimated prior to a nursing cycle and at the end of the cycle (after 9 weeks). Results The results showed that black carp affect the density of snail populations in both semi-field and field conditions. The standing crop of snails in nursery ponds, however, was too high for 2 specimens to greatly reduce snail density within the relatively short nursing cycle. Conclusions We conclude that the black carp can be used in nursery ponds in Northern Vietnam for snail control. Juvenile black carp weighing 100 - 200g should be used because this size primarily prey on intermediate hosts of FZT

Juvenile Firesetting.

Peters, Brittany; Freeman, Bradley

2016-01-01

Juvenile firesetting is a significant cause of morbidity and mortality in the United States. Male gender, substance use, history of maltreatment, interest in fire, and psychiatric illness are commonly reported risk factors. Interventions that have been shown to be effective in juveniles who set fires include cognitive behavior therapy and educational interventions, whereas satiation has not been shown to be an effective intervention. Forensic assessments can assist the legal community in adjudicating youth with effective interventions. Future studies should focus on consistent assessment and outcome measures to create more evidence for directing evaluation and treatment of juvenile firesetters. Copyright © 2016 Elsevier Inc.

Background Juvenile polyps are distinct hamartomatous malformations of the gastrointestinal tract that may occur in the heritable juvenile polyposis syndrome (JPS) or sporadically. Histologically, juvenile polyps are characterised by a marked increase of the stromal cell compartment but, an epithelial phenotype has also been reported. JPS has an increased risk of colorectal cancer but sporadic juvenile polyps do not. In 50–60% of JPS patients a germline mutation of the TGF-β/BMP pathway genes SMAD4 or BMPR1A is found. This study compares the histological phenotype of juvenile polyps with a SMAD4 or BMPR1A germline mutation and sporadic juvenile polyps. Methods H&E slides of 65 JPS polyps and 25 sporadic juvenile polyps were reviewed for histological features and dysplasia. Systematic random crypt and stroma counts were obtained by count stereology and a crypt-stroma ratio was determined. All polyps were subsequently categorised as type A (crypt-stroma ratio <1.00) or type B (crypt-stroma ratio ≥1.00), the latter referring to the epithelial phenotype. Cell cycle activity was assessed using immunohistochemistry of the proliferation marker Ki67, and mutation analysis was conducted for KRAS and APC to determine the involvement of the adenoma-carcinoma sequence. Results Juvenile polyps with a SMAD4 germline mutation were predominantly type B, whereas, type A was more common among juvenile polyps with a BMPR1A germline mutation, but this distinction could not be ascribed to differences in cell cycle activity. Dysplasia was equally common in JPS polyps with either a SMAD4 or BMPR1A germline mutation, where the involvement of the adenoma-carcinoma sequence does not seem to play a distinct role. Conclusion juvenile polyps in the setting of JPS exhibit distinct phenotypes correlating with the underlying genetic defect. PMID:21412070

Juvenile curfews: are they an effective and constitutional means of combating juvenile violence?

PubMed

Fried, C S

2001-01-01

Curfew ordinances have become a popular way to attempt to combat juvenile crime and victimization. Although the Supreme Court has yet to hear a curfew case, several constitutional challenges have been brought in lower federal courts. The cases are replete with psychological assumptions for which there is limited empirical evidence. In applying the "strict scrutiny" standard, several courts have also questioned whether juvenile curfews are narrowly tailored to further the State's interest in reducing juvenile crime and victimization. While public opinion and reports from several police jurisdictions support the utility of juvenile curfews, recent empirical studies indicate that curfews are not effective at reducing juvenile offending or victimization. This paper argues that the emerging evidence does not support the use of juvenile curfews and urges policy makers and the courts to examine the efficacy of curfew legislation. Directions for future research that could be helpful to the courts in applying the Bellotti factors to curfew cases are also suggested. Copyright 2001 John Wiley & Sons, Ltd.

Stevenson, Margaret C; Smith, Amy C; Sekely, Ady; Farnum, Katlyn S

2013-01-01

We investigated demographic predictors of support for juvenile sex offender registration policies, including education level, gender, political orientation, and age. Participants were 168 individuals recruited from public places in a Midwest community (45% women; M age = 42). In line with hypotheses, as education level increased, support for juvenile registration decreased, as did the belief that juvenile registration protects the community. In addition, as education level increased, belief that the juvenile understood his actions decreased, as did support for juvenile registration when it is framed as ineffective at reducing sex crime. These beliefs mediated the relationship between education level and diminished support for juvenile registration. Implications of these results for the advancement of effective juvenile sex offender policy are discussed.

Juvenile idiopathic arthritis.

PubMed

Boros, Christina; Whitehead, Ben

2010-09-01

Juvenile idiopathic arthritis is the most common rheumatic disease in childhood, occurring in approximately 1:500 children. Despite a recent expansion in treatment options and improvement of outcomes, significant morbidity still occurs. This article outlines the clinical manifestations, assessment, detection of complications, treatment options and monitoring requirements, with the aid of guidelines recently published by The Royal Australian College of General Practitioners, which provide practical support for general practitioners to ensure best practice care and to prevent lifelong disability in patients with juvenile idiopathic arthritis. General practice plays an important role in the early detection, initial management and ongoing monitoring of children with juvenile idiopathic arthritis. Early detection involves understanding the classification framework for subtypes of juvenile idiopathic arthritis, and being aware of the clinical manifestations and how to look for them, through history, examination and appropriate investigation. The major extra-articular manifestations of juvenile idiopathic arthritis are uveitis and growth disturbance. Treatment options include nonsteroidal anti-inflammatory drugs, methotrexate, biologic agents, and corticosteroids. Management using a multidisciplinary approach can prevent long term sequelae. Unfortunately, approximately 50% of children will have active disease as adults.

In the present investigation, probiotic potential (antagonistic activity, enzyme production, hemolytic activity, biosafety, antibiotic sensitivity and bile tolerance level) of Bacillus subtilis LR1 was evaluated. Bacteriocin produced by the bacterial strain B. subtilis LR1 isolated from the gastrointestinal tract of Labeo rohita was purified and characterized. The molecular weight of the purified bacteriocin was ~50 kDa in 12 % Native PAGE and showed inhibitory activity against four fish pathogens such as Bacillus mycoides, Aeromonas salmonicida, Pseudomonas fluorescens and Aeromonas hydrophila. The purified bacteriocin was maximally active at temperature 40 °C and pH 7.0, while none of the tested surfactants affect the bacteriocin activity. Extracellular enzyme activity of the selected bacterial strain was also evaluated. Amylase activity was estimated to be highest (38.23 ± 1.15 µg of maltose liberated mg -1  protein ml -1 of culture filtrate) followed by cellulase and protease activity. The selected bacterium was sensitive to most of the antibiotics used in this experiment, can tolerate 0.25 % bile salt and non-hemolytic in nature. Finally, the efficiency of the proposed probiotic candidate was evaluated in in vivo condition. It was detected that the bacterial strain can effectively reduce bacterial pathogenicity in Indian major carps.

Fish is a vital food for humans and many animals. We report an environmental monitoring study to assess the trace metals in fish species caught from Arabian Sea and commercially available in the coastal city Karachi, Pakistan. Heavy metals such as copper, iron, lead and cadmium were determined in the skin, fillet and heart of the fish species Pampus argenteus, Epinephelus chlorostigma, Rachycentron canadum, Scomberomorus commerson, Johnius belangerii, Labeo rohita, Lutjanus argentimaculatus, Trachinotus blochii, Pomadsys olivaceum and Acanthopagrus berda by the atomic absorption spectrophotometer. The concentration (mg kg(-1), dry weight) range was: Cd (0.00-0.041), Cu (0.006-0.189), Fe (0.413-4.952) and Pb (0.00-0.569). Cadmium, copper and iron levels were below the tolerable limits whereas concentration of lead in the skins of S. commerson, E. chlorostigma, J. belangerii, A. berda; L. argentimaculatus, fillets of J. belangerii, E. chlorostigma and in the heart of J. belangerii exceeded the recommended limits. Therefore fish skin should be discouraged as food for humans or animals. The results indicate that a number of fish species have higher concentration of heavy metals dangerous for human health. Since the fish P. olivaceum (Dhotar) has the lowest level of trace metals therefore we recommend it for breeding and human consumption.

Acanthogyrus (Acanthosentis) kashmirensis n. sp. is described from recently collected acanthocephalan specimens in the Jhelum River in northern Kashmir that are conspecific with Neoechinorhynchus kashmirensis Fotedar and Dhar, 1977 originally described in a Ph.D. thesis in 1972 from 4 species of cyprinid fishes: Tor tor Hamilton, Bangana diplostoma (Heckel) (syn. Labeo diplostoma Heckel), Labeo rohita Hamilton, and Ptychobarbus sp. Steindachner. The poor unpublished diagnosis was followed by 1 uninformative abstract in a scientific meeting in 1977. The acanthocephalan was later designated as invalid because of the lack of a formal published description and absence of information on deposited type or voucher specimens. Recent collections of specimens of the same species were made from 2 other cyprinid species of cyprinid fishes, Schizothorax plagiostomus Heckel and Schizothorax labiatus (McClelland) from the Sandran River, a tributary of the Jhelum River, in southern Kashmir. It is now possible to provide a full description of these specimens and reassign them in the subgenus Acanthosentis Verma and Datta, 1929 based on the finding of circles of vestigial spines at the anterior end of the trunk of male and female specimens. These vestigial spines are barely visible and easy to miss with optical microscopy. The new species is also characterized by having (1) a para-receptacle structure in males and females, (2) unique double Saefftigen's pouches, (3) large round single-nucleated cells in the proboscis, and (4) the lemnisci being either equal or distinctly unequal with no intermediate states. A key to the species of Acanthosentis of the Indian subcontinent is provided. Histopathological sections show extensive damage to the host intestine with subsequent blood loss, cell necrosis, and attempted encapsulation. Results of the energy dispersive X-ray analysis (EDAX) study show hollow hooks high in sulfur but with limited calcium ions. Hooks of most acanthocephalans

The development of Diapterus peruvianus (Sauvage 1879) is based on 60 larvae collected in superficial tows made in Bahía Concepción, and on 16 pre-juvenile and juvenile organisms collected in Bahía de La Paz, B. C. S., México, using a standard plankton net and a rectangular epibenthonic net, respectively. Larvae of D. peruvianus show three large blotches on the dorsum of the gut that can fuse together and give the appearance of one large continuous blotch. There are two to three pre-anal pigments and 16 post-anal pigments in the ventral midline; cephalic pigments are present from the postflexion stage, as well as a serrated preoperculum. The pre-juvenile and juvenile organisms are distinguished by their body depth, the anal-fin formula, the serrated pre-operculum and the base pigments in the dorsal and anal fins.

Telepsychiatry is emerging as a valuable means of providing mental health care in juvenile justice settings. Youth in the juvenile justice system have high levels of psychiatric morbidity. State and local juvenile justice systems frequently struggle to provide specialized psychiatric care, as these systems have limited resources and often operate in remote locations. Case studies in the use of telepsychiatry to provide improved care in juvenile corrections in 4 states are described, along with a review of advantages and disadvantages of telepsychiatry in these settings.

Migration conveys an immense challenge, especially for juvenile birds coping with enduring and risky journeys shortly after fledging. Accordingly, juveniles exhibit considerably lower survival rates compared to adults, particularly during migration. Juvenile white storks (Ciconia ciconia), which are known to rely on adults during their first fall migration presumably for navigational purposes, also display much lower annual survival than adults. Using detailed GPS and body acceleration data, we examined the patterns and potential causes of age-related differences in fall migration properties of white storks by comparing first-year juveniles and adults. We compared juvenile and adult parameters of movement, behaviour and energy expenditure (estimated from overall dynamic body acceleration) and placed this in the context of the juveniles' lower survival rate. Juveniles used flapping flight vs. soaring flight 23% more than adults and were estimated to expend 14% more energy during flight. Juveniles did not compensate for their higher flight costs by increased refuelling or resting during migration. When juveniles and adults migrated together in the same flock, the juvenile flew mostly behind the adult and was left behind when they separated. Juveniles showed greater improvement in flight efficiency throughout migration compared to adults which appears crucial because juveniles exhibiting higher flight costs suffered increased mortality. Our findings demonstrate the conflict between the juveniles' inferior flight skills and their urge to keep up with mixed adult-juvenile flocks. We suggest that increased flight costs are an important proximate cause of juvenile mortality in white storks and likely in other soaring migrants and that natural selection is operating on juvenile variation in flight efficiency. © 2016 The Authors.

Within the past decade, reliance on the juvenile justice system to meet the needs of juvenile offenders with mental health concerns has increased. Due to this tendency, research has been conducted on the effectiveness of various intervention and treatment programs/approaches with varied success. Recent literature suggests that because of interrelated problems involved for youth in the juvenile justice system with mental health issues, a dynamic system of care that extends beyond mere treatment within the juvenile justice system is the most promising. The authors provide a brief overview of the extent to which delinquency and mental illness co-occur; why treatment for these individuals requires a system of care; intervention models; and the juvenile justice systems role in providing mental health services to delinquent youth. Current and future advancements and implications for practitioners are provided. PMID:26901213

Juvenile Hormone Induction of Esterases: A Mechanism for the Regulation of Juvenile Hormone Titer

PubMed Central

Whitmore, Donald; Whitmore, Elaine; Gilbert, Lawrence I.

1972-01-01

Within a few hours after injection of juvenile hormone into Hyalophora gloveri pupae, several fast-migrating carboxylesterases (EC 3.1.1.1) that are sensitive to diisopropylfluorophosphate appear in the hemolymph. Treatment of the pupae with puromycin or actinomycin D prevents the appearance of these hemolymph enzymes, suggesting de novo synthesis of the carboxylesterases. Of the several other compounds investigated, only a potent mimic of the juvenile hormone is able to induce these enzymes. When the induced enzymes are incubated in vitro with 14C-labeled juvenile hormone, the hormone is rapidly and efficiently degraded. It is suggested that these induced carboxylesterases play an important role in the regulation of juvenile hormone titer. Images PMID:4504374

There is hardly any study examining exposure to traumatic events and post-traumatic stress disorder (PTSD) among juvenile justice populations in Nigeria or any part of sub-Saharan Africa. We examined the prevalence and trauma determinants of PTSD among a cohort of juvenile justice inmates in Nigeria, compared with a cohort of school-going adolescents. Ninety percent (90%) of the juvenile justice inmates reported exposure to at least one lifetime traumatic event with higher mean incident events, compared with 60% among the comparison group (p=.001). Juvenile justice inmates had significantly higher prevalence rate of current and lifetime PTSD than the comparison group (current: 5.8% vs. 1.4%; lifetime: 9.7% vs. 2.8%, p<.05). Mean incident traumatic event was statistically significantly higher among juvenile justice inmates who had PTSD. Posttraumatic stress symptoms are common among adolescents coming in contact with the juvenile justice system. Implications for holistic service provisioning in juvenile justice administration are discussed.

Juvenile morphology in baleen whale phylogeny.

PubMed

Tsai, Cheng-Hsiu; Fordyce, R Ewan

2014-09-01

Phylogenetic reconstructions are sensitive to the influence of ontogeny on morphology. Here, we use foetal/neonatal specimens of known species of living baleen whales (Cetacea: Mysticeti) to show how juvenile morphology of extant species affects phylogenetic placement of the species. In one clade (sei whale, Balaenopteridae), the juvenile is distant from the usual phylogenetic position of adults, but in the other clade (pygmy right whale, Cetotheriidae), the juvenile is close to the adult. Different heterochronic processes at work in the studied species have different influences on juvenile morphology and on phylogenetic placement. This study helps to understand the relationship between evolutionary processes and phylogenetic patterns in baleen whale evolution and, more in general, between phylogeny and ontogeny; likewise, this study provides a proxy how to interpret the phylogeny when fossils that are immature individuals are included. Juvenile individuals in the peramorphic acceleration clades would produce misleading phylogenies, whereas juvenile individuals in the paedomorphic neoteny clades should still provide reliable phylogenetic signals.

Juvenile Angiofibroma: Evolution of Management

Nicolai, Piero; Schreiber, Alberto; Bolzoni Villaret, Andrea

2012-01-01

Juvenile angiofibroma is a rare benign lesion originating from the pterygopalatine fossa with distinctive epidemiologic features and growth patterns. The typical patient is an adolescent male with a clinical history of recurrent epistaxis and nasal obstruction. Although the use of nonsurgical therapies is described in the literature, surgery is currently considered the ideal treatment for juvenile angiofibroma. Refinement in preoperative embolization has provided significant reduction of complications and intraoperative bleeding with minimal risk of residual disease. During the last decade, an endoscopic technique has been extensively adopted as a valid alternative to external approaches in the management of small-intermediate size juvenile angiofibromas. Herein, we review the evolution in the management of juvenile angiofibroma with particular reference to recent advances in diagnosis and treatment. PMID:22164185

Juvenile delinquency, the juvenile courts and the settlement movement 1908-1950: Basil Henriques and Toynbee Hall.

PubMed

Bradley, Katharine

2008-01-01

This article explores the relationship between the voluntary sector and the juvenile courts in the period c.1908-1950. It specifically examines the relationship between the settlement movement and the early juvenile courts by analysing the Inner London Juvenile Court, which sat at Toynbee Hall in the East End of London between 1929 and 1953. The settlements, which brought young graduates to deprived urban areas to undertake voluntary social work, were heavily involved in boys' clubs. Many of those who began their careers in settlement youth work went on to work with the early juvenile courts, viewing their experience in clubs as a vital foundation for this work. This article focuses on Basil Henriques, a former resident of Toynbee Hall, warden of the Bernhard Baron Settlement in Stepney and magistrate at the Inner London Juvenile Court, and his 1950 book, Indiscretions of a Magistrate. It concludes that, by critically examining Basil Henriques and Indiscretions, it is possible to begin to fully explore the discourses around citizenship, gender, class and race that informed the views and practices of juvenile court magistrates in the period in which the voluntary sector and the welfare state underwent profound change.

Fish erythrocytes as biomarkers for the toxicity of sublethal doses of an azo dye, Basic Violet-1 (CI: 42535).

PubMed

Kaur, Kirandeep; Kaur, Arvinder

2015-02-01

The aim of the present study was to investigate poikilocytosis in Labeo rohita (an important food fish) as an early indicator of stress due to an azo dye, Basic Violet-1 (CI: 42535). This dye was observed to be very toxic to test fish (96 h LC50 as0.45 mg/L dye). Fish were given short-term (96 h) and subchronic (150 days) exposures to the dye, and poikilocytosis was recorded under light and scanning electron microscopy (SEM). Light microscopy helped in identification of micronuclei along with irregularities, notches, blebs, lobes, crenation, clumps, chains, spherocytes, vacuolation, and necrosis in erythrocytes. However, SEM indicated shrinkage, oozing of cytoplasm, and several new abnormal shapes including marginal foldings, discocytes, keratocytes, dacrocytes, degmacytes, acanthocytes, echinocytes, protuberances, stomatocytes, drepanocytes, holes in the membrane, stippling/spicules, crescent-shaped cells, triangular cells, and pentagonal cells. Earlier studies speculated changes in the membrane to be responsible for clumping and chaining of erythrocytes, whereas the present SEM study clearly indicates that oozing out of cytoplasm is also responsible for the formation of chains and clumps. This study also shows that erythrocytes exhibit pathological symptoms before the appearance of other external symptoms such as abnormal behavior or mortality of fish. There was a dose- and duration-dependent increase; therefore, poikilocytosis, especially echinocytes, spherocytes, and clumps, can act as a biomarker for the stress caused by azo dyes.

Snakehead Channa striata is an important freshwater food fish in many Southeast Asian countries. Three monoclonal antibodies (C9, C10 and D10) were developed against purified serum immunoglobulins of Channa striata (Cs-Ig) and characterized. C9 and D10 MAbs were specific to heavy chain, while C10 MAb detected only unreduced Cs-Ig in western blotting. In competitive ELISA, C9 and C10 MAbs were specific to C. striata Ig and showed no cross reactivity with serum Ig of other fish species i.e. Channa punctatus, Channa marulius, Clarias batrachus and Labeo rohita. D10 MAb showed reactivity to serum Ig of C. striata and C. marulius. In FACS analysis of gated lymphocytes, the percentage of Ig+ cells detected by C9 MAb was 18.2%, 27.7% and 10.3% in blood, spleen and kidney, respectively (n=3, body weight 500-600 g). However, only a few cells (0.5%) were found to be Ig+ in thymus (n=5). C9 MAb was also successfully employed to demonstrate Ig+ cells in blood smears and formalin fixed sections of spleen and kidney. These findings suggest that the spleen plays an important role in humoral immunity as compared to head kidney. Further, these MAbs can be useful immunological tool in monitoring health status of cultured C. striata. Copyright © 2010 Elsevier Ltd. All rights reserved.

Study of the effects of the casein derived bitter tastant on the melanophores in milieu with the melatonin receptors.

PubMed

Mubashshir, Md; Ahmed, Fraz; Ovais, Mohd

2011-10-01

The present study was undertaken to ascertain whether the casein derived bitter tastant Cyclo (Leu-Trp) [CLT] has an affinity or not for the particular receptors of the pineal hormone, melatonin, on the melanophores of a major carp Labeo rohita (Ham.). The bitter tastant CLT, in the dose range of 3.34×10(-16) M to 3.34×10(-4) M, has induced an aggregatory effect but not in a dose dependent manner. Binding of CLT with the receptors may vary at different concentrations. Denervation of the melanophores has shown a complete inhibition of the CLT mediated aggregation. Prazosin has partially inhibited the aggregatory effect of CLT. Moreover, the bitter tastant's response is mediated through the α2 adrenoceptors only at particular dose ranges. The MT1 and MT2 melatonin receptor antagonist luzindole and the MT2 specific antagonist K185 have perfectly blocked the aggregatory effects of CLT. We have found that the CLT mediated aggregatory effect is dependent upon the release of neurotransmitters and the two subtypes of melatonin (MT) receptors (MT1 and MT2) possess a perfect affinity towards the bitter tastant CLT. Our study demands a need to further make a clinical research on the effects of bitter tastants on the physiology of the biological rhythm maintaining hormone melatonin.

Autosomal dominant juvenile recurrent parotitis.

1998-01-01

Juvenile recurrent parotitis is a common cause of inflammatory salivary gland swelling in children. A variety of aetiological factors has been proposed for the condition. Here we present a family where four members had juvenile recurrent parotitis and where two other family members may have had an atypical form of the condition. The segregation pattern in the family is consistent with autosomal dominant inheritance with incomplete penetrance and this suggests that, at least in some cases, genetic factors may be implicated in juvenile recurrent parotitis.

To the best of our knowledge, this is the youngest case reported in the literature. Methods: We report a rare case of an 8-month-old male infant who presented with chronic anemia and gastrointestinal bleeding initially. Panendoscopy and abdominal computed tomography showed multiple polyposis throughout the entire alimentary tract leading to intussusception. Technetium-99m-labeled red blood cell (RBC) bleeding scan revealed the possibility of gastrointestinal tract bleeding in the jejunum. Histopathological examination on biopsy samples showed Peutz-Jeghers syndrome was excluded, whereas the diagnosis of juvenile polyposis syndrome was established. Results: Enteroscopic polypectomy is the mainstay of the treatment. However, polyps recurred and occupied the majority of the gastrointestinal tract in 6 months. Supportive management was given. The patient expired for severe sepsis at the age of 18 months. Conclusion: Juvenile polyposis syndrome is an inherited disease, so it is not possible to prevent it. Concerning of its poor outcome and high mortality rate, it is important that we should increase awareness and education of the parents at its earliest stages. PMID:27631205

Defective neutrophil chemotaxis in juvenile periodontitis.

PubMed Central

Clark, R A; Page, R C; Wilde, G

1977-01-01

Neutrophil chemotaxis was evaluated in nine patients with juvenile periodontitis, with normal subjects and patients with the adult form of periodontitis as controls. Defective chemotactic responses were observed in neutrophils from seven of nine juvenile patients, and a reduced level of complement-derived chemotactic activity was demonstrated in serum from four patients. These determinations were normal in all the patients with adult periodontitis. Serum from five of the juvenile patients contained a heat-stable, non-dialyzable factor that markedly inhibited the chemotaxis of normal neutrophils. Thus the characteristic tissue destruction seen in juvenile periodontitis may be, at least in part, a consequence of a failure of host defense mechanisms. PMID:591063

Juvenile dispersal in Calomys venustus (Muridae: Sigmodontinae)

Priotto, José; Steinmann, Andrea; Provensal, Cecilia; Polop, Jaime

2004-05-01

Both spacing behaviour and dispersal movement are viewed as hierarchical processes in which the effects may be expressed at spatial scale. This research was carried out to examine the hypothesis that the presence of parents promotes the dispersal of juveniles from their natal nest and their father or mother home-range, in Calomys venustus.The study was carried out in four 0.25 ha fences (two controls and two experimentals), in a natural pasture. This study had two periods: Father Removal (FR) (August and December 1997; year one) and Mother Removal (MR) (August 1998 and January 1999; year two). For the FR treatment fathers were removed after juveniles were born, but in the MR treatment mothers were removed after the juveniles were weaned. The effect of parents on the dispersal distance of juveniles was analysed with respect to their natal nest and their mother and father home-range. Dispersal distance from the nest of C. venustus was independent of either male or female parent. Juveniles were more dispersing in relation to the centre of activity of their mothers than to that of their fathers, and females were more dispersing than males. Female juveniles overlap their home-range with their parents less than male juveniles do. The differences observed between female and male juveniles would be related to their different sexual maturation times, as well as to the female territoriality.

Iatrogenic effect of juvenile justice.

PubMed

Gatti, Uberto; Tremblay, Richard E; Vitaro, Frank

2009-08-01

The present study uses data from a community sample of 779 low-SES boys to investigate whether intervention by the juvenile justice system is determined, at least in part, by particular individual, familial and social conditions, and whether intervention by the juvenile courts during adolescence increases involvement in adult crime. The study considers self-reported crime in childhood and adolescence, and introduces individual, familial and social variables into its analysis. The results show that youths who are poor, impulsive, poorly supervised by their parents, and exposed to deviant friends are more likely, for the same degree of antisocial behavior, to undergo intervention by the Juvenile Court, and that this intervention greatly increases the likelihood of involvement with the penal system in adulthood. The results also show that the various measures recommended by the Juvenile Court exert a differential criminogenic effect; those that involve placement have the most negative impact.

Eliminating the Competency Presumption in Juvenile Delinquency Cases.

PubMed

Katner, David R

2015-01-01

The legal presumption used in virtually all juvenile delinquency cases in the U.S. is that all juveniles are competent to stand trial. This Article calls for the elimination of that legal presumption, which is historically based on the Dusky v. United States decision and in the adult criminal justice system. The recent decisions of the U.S. Supreme Court recognize the developmental and organic brain differences between adults and juveniles. Current research demonstrates a higher frequency rate of incompetence based on intellectual deficiencies among children when compared with adults found to be not legally competent to stand trial. By eliminating the competency presumption for juveniles in both delinquency and adult criminal proceedings, the party seeking an adjudication would be responsible for establishing that the accused juvenile is in fact, competent to stand trial. Foreign jurisdictions in Europe, Asia, Africa, and South America have long required higher thresholds--at least fourteen years of age--for holding juveniles accountable for criminal misconduct, none of them presuming that juveniles are competent to go to trial. In the alternative, by expanding the factors currently in use for determination of juvenile competency by adding developmental immaturity and mental illness, juvenile justice systems could identify the reduction of recidivist offending as the primary systemic objective.

Juvenile crime and criminal justice: resolving border disputes.

PubMed

Fagan, Jeffrey

2008-01-01

Rising juvenile crime rates during the 1970s and 1980s spurred state legislatures across the country to exclude or transfer a significant share of offenders under the age of eighteen to the jurisdiction of the criminal court, essentially redrawing the boundary between the juvenile and adult justice systems. Jeffrey Fagan examines the legal architecture of the new boundary-drawing regime and how effective it has been in reducing crime. The juvenile court, Fagan emphasizes, has always had the power to transfer juveniles to the criminal court. Transfer decisions were made individually by judges who weighed the competing interests of public safety and the possibility of rehabilitating young offenders. This authority has now been usurped by legislators and prosecutors. The recent changes in state law have moved large numbers of juveniles into the adult system. As many as 25 percent of all juvenile offenders younger than eighteen, says Fagan, are now prosecuted in adult court. Many live in states where the age boundary between juvenile and criminal court has been lowered to sixteen or seventeen. The key policy question is: do these new transfer laws reduce crime? In examining the research evidence, Fagan finds that rates of juvenile offending are not lower in states where it is relatively more common to try adolescents as adults. Likewise, juveniles who have been tried as adults are no less likely to re-offend than their counterparts who have been tried as juveniles. Treating juveniles as adult criminals, Fagan concludes, is not effective as a means of crime control. Fagan argues that the proliferation of transfer regimes over the past several decades calls into question the very rationale for a juvenile court. Transferring adolescent offenders to the criminal court exposes them to harsh and sometimes toxic forms of punishment that have the perverse effect of increasing criminal activity. The accumulating evidence on transfer, the recent decrease in serious juvenile

A study of the complex relationships between the patient characteristics, family and environmental influences, physician's behaviour and the demands of the disease with its management in Juvenile Diabetics was taken up at a general hospital. 90 subjects were selected for the study and grouped into three. Group A consisted of 30 Juvenile Diabetics, Group B of 30 Adult Diabetics and Group C of 30 Normal healthy adolescents. The impact of the illness was measured on the Diabetes Impact Measurement Scale (DIMS), the behavioural deviations and the parental attitudes towards child rearing on the Fallstrom's Questionnaire (FQ) and the family environment on the Family Climate Scale (FCS). Psychiatric morbidity was assessed using DSM-IV criteria. Group A & B were compared on the DIMS and Group A & C on FQ & FCS. Adult diabetics had a greater impact of diabetes. Juvenile diabetics had significantly higher frequency of behavioural deviations as compared to controls. Also there was a higher number of responses on questions indicating an overprotecting attitude amongst parents of juvenile diabetics. There was an increased incidence of psychiatric morbidity in juvenile diabetics as compared to normal adolescents irrespective of the family environment. The results are discussed in relation to current literature. PMID:21430802

Movements of juvenile common ravens in an arid landscape

Webb, W.C.; Boarman, W.I.; Rotenberry, J.T.

2009-01-01

Movement patterns of juvenile birds are poorly understood, yet critically important ecological phenomena, especially for species with a prolonged juvenile period. We evaluated postfledging movements of juvenile common ravens (Corvus corax) in a western Mojave Desert landscape composed of a mosaic of natural and anthropogenic elements. Generally, ravens do not begin breeding until after their fourth year. We marked 2 annual cohorts of juvenile ravens and followed them from dispersal from their natal territory for up to 33 months. Movements of juvenile common ravens were similar for males and females. Conspecifics and confined livestock feeding operations represented important resources for juvenile ravens, and juveniles were rarely located in open desert. However, initial movements from the natal territory to the nearest communal point subsidy rather than the closest anthropogenic resource suggested juvenile dispersal was influenced by the combination of conspecifics and anthropogenic resources, rather than the distribution of those resources. Land managers concerned with growing raven populations should reduce access to concentrated anthropogenic resources such as landfills and dairies, which serve as important resources for juveniles. Because juvenile ravens rarely venture into open desert, reducing their numbers by lethal removal or other means is unlikely to lessen raven predation of desert tortoises (Gopherus agassizii).

Prospective Prediction of Juvenile Homicide/Attempted Homicide among Early-Onset Juvenile Offenders

PubMed Central

Baglivio, Michael T.; Wolff, Kevin T.

2017-01-01

While homicide perpetrated by juveniles is a relatively rare occurrence, between 2010 and 2014, approximately 7%–8% of all murders involved a juvenile offender. Unfortunately, few studies have prospectively examined the predictors of homicide offending, with none examining first-time murder among a sample of adjudicated male and female youth. The current study employed data on 5908 juvenile offenders (70% male, 45% Black) first arrested at the age of 12 or younger to prospectively examine predictors of an arrest for homicide/attempted homicide by the age of 18. Among these early-onset offenders, males, Black youth, those living in households with family members with a history of mental illness, those engaging in self-mutilation, and those with elevated levels of anger/aggression (all measured by age 13) were more likely to be arrested for homicide/attempted homicide by age 18. These findings add to the scant scientific literature on the predictors of homicide, and illustrate potential avenues for intervention. PMID:28212340

Antibodies in juvenile-onset myositis.

PubMed

Tansley, Sarah L

2016-11-01

Juvenile-onset myositis is a highly heterogeneous disease. Myositis-specific and associated autoantibodies provide a potential means of subdividing patients into clinically homogenous subgroups. Given the increasing availability of autoantibody testing, this review explores the phenotypes associated with different autoantibodies in juvenile-onset myositis and the potential clinical utility of autoantibody testing. Autoantibodies can be identified in 60-70% of children with myositis and the recent discovery of novel myositis-associated autoantibodies in adult patients suggests this may increase in the near future. Detailed phenotype descriptions are now known for several autoantibodies commonly identified in juvenile-onset disease. Whilst there is insufficient evidence to recommend a differential treatment approach based on autoantibody status, it is becoming increasingly clear that some autoantibody subgroups are often treatment resistant and may benefit from a more aggressive approach. The validation of nonspecialised methods for myositis-specific autoantibody detection should lead to more widely available testing. In juvenile-onset disease, this will provide detailed prognostic information and in the future may also influence approach.

A Practical Approach to Juvenile Dermatomyositis and Juvenile Scleroderma.

PubMed

McCann, Liza J; Pain, Clare E

2016-02-01

Juvenile dermatomyositis and juvenile scleroderma are rare multisystem autoimmune disorders. Although they share some pathognomonic hallmarks with adult onset myositis or scleroderma, there are significant differences in presentation, characteristics and associated features when the diseases present in childhood. In view of this, and the rarity of the conditions, it is important for care to be led by teams with expertise in pediatric rheumatology conditions. Prognosis has improved significantly in the West; likely due to early diagnosis and aggressive treatment with immunosuppressive medications. However, this trend is not replicated in the developing world. Early recognition of these diseases is crucial to achieve rapid and sustained remission and prevent disease or medication associated complications. This article aims to provide a practical overview for recognition, diagnosis and treatment of these conditions.

Adolescent neglect, juvenile delinquency and the risk of recidivism.

PubMed

Ryan, Joseph P; Williams, Abigail B; Courtney, Mark E

2013-03-01

Victims of child abuse and neglect are at an increased risk of involvement with the juvenile justice and adult correctional systems. Yet, little is known about the continuation and trajectories of offending beyond initial contact with law enforcement. Neglect likely plays a critical role in continued offending as parental monitoring, parental rejection and family relationships are instrumental in explaining juvenile conduct problems. This study sought to determine whether neglect is associated with recidivism for moderate and high risk juvenile offenders in Washington State. Statewide risk assessments and administrative records for child welfare, juvenile justice, and adult corrections were analyzed. The sample was diverse (24 % female, 13 % African American, 8 % Hispanic, 5 % Native American) and included all moderate and high risk juvenile offenders screened by juvenile probation between 2004 and 2007 (n = 19,833). Official records from child protection were used to identify juvenile offenders with a history of child neglect and to identify juvenile offenders with an ongoing case of neglect. Event history models were developed to estimate the risk of subsequent offending. Adolescents with an ongoing case neglect were significantly more likely to continue offending as compared with youth with no official history of neglect. These findings remain even after controlling for a wide range of family, peer, academic, mental health, and substance abuse covariates. Interrupting trajectories of offending is a primary focus of juvenile justice. The findings of the current study indicate that ongoing dependency issues play a critical role in explaining the outcomes achieved for adolescents in juvenile justice settings. The implications for improved collaboration between child welfare and juvenile justice are discussed.

Do juveniles bully more than young offenders?

PubMed

Ireland, Jane L

2002-04-01

This study compares bullying behaviour among juvenile and young offenders and incorporates two different methods to measure bullying. Ninety-five male juvenile and 196 male young offenders completed two questionnaires, one that measured bullying directly and one that measured behaviours indicative of "being bullied" or of "bullying others". Juveniles perceived a higher extent of bullying than young offenders. Juveniles reported significantly more physical, psychological or verbal and overall direct forms of bullying behaviour than young offenders. A number of differences were found between juveniles and young offenders with regard to the types of prisoners likely to become victims, who they would advise a victim to speak to and how bullying could be prevented. The results are discussed in relation to developmental theories of aggression and how bullying behaviour can be defined and measured among prisoners.

Law & psychiatry: punishing juveniles who kill.

PubMed

Appelbaum, Paul S

2012-10-01

Punishment of juvenile murderers forces policy makers to weigh the developmental immaturity of adolescents against the heinousness of their crimes. The U.S. Supreme Court has progressively limited the severity of punishments that can be imposed on juveniles, holding that their impulsivity, susceptibility to peer pressure, and more fluid character render them less culpable for their actions. Having eliminated the death penalty as a punishment, the Court recently struck down mandatory life sentences without prospect of parole. The decision is interesting for its emphasis on rehabilitation, opening the door to further restrictions on punitive sentences for juveniles-and perhaps for adults too.

Juvenile localized scleroderma (LS) is a chronic inflammatory skin disorder associated with substantial morbidity and disability. Although a wide range of therapeutic strategies has been reported in the literature, a lack of agreement on treatment specifics and accepted methods for clinical assessment has made it difficult to compare approaches and identify optimal therapy. Our objective was to develop standardized treatment plans, clinical assessments, and response criteria for active, moderate to high severity juvenile LS. A core group of pediatric rheumatologists, dermatologists, and a lay advisor was engaged by the Childhood Arthritis and Rheumatology Research Alliance (CARRA) to develop standardized treatment plans and assessment parameters for juvenile LS using consensus methods/nominal group techniques. Recommendations were validated in 2 face-to-face conferences with a larger group of practitioners with expertise in juvenile LS and with the full membership of CARRA, which encompasses the majority of pediatric rheumatologists in the US and Canada. Consensus was achieved on standardized treatment plans that reflect the prevailing treatment practices of CARRA members. Standardized clinical assessment methods and provisional treatment response criteria were also developed. Greater than 90% of pediatric rheumatologists responding to a survey (66% of CARRA membership) affirmed the final recommendations and agreed to utilize these consensus plans to treat patients with juvenile LS. Using consensus methodology, we have developed standardized treatment plans and assessment methods for juvenile LS. The high level of support among pediatric rheumatologists will support future comparative effectiveness studies and enable the development of evidence-based guidelines for the treatment of juvenile LS.

Studies of adult antisocial behavior or criminality usually find genetic factors to be more important than the family environment, whereas studies of delinquency find the family environment to be more important. We compared DSM-III-R antisocial personality disorder symptoms before vs after the age of 15 years within a sample of twins, rather than comparing across studies. We administered the Diagnostic Interview Schedule Version III-revised by telephone to 3226 pairs of male twins from the Vietnam Era Twin Registry. Biometrical modeling was applied to each symptom of antisocial personality disorder and summary measures of juvenile and adult symptoms. Five juvenile symptoms were significantly heritable, and five were significantly influenced by the shared environment. Eight adult symptoms were significantly heritable, and one was significantly influenced by the shared environment. The shared environment explained about six times more variance in juvenile anti-social traits than in adult traits. Shared environmental influences on adult antisocial traits overlapped entirely with those on juvenile traits. Additive genetic factors explained about six times more variance in adult vs juvenile traits. The juvenile genetic determinants overlapped completely with genetic influences on adult traits. The unique environment (plus measurement error) explained the largest proportion of variance in both juvenile and adult antisocial traits. Characteristics of the shared or family environment that promote antisocial behavior during childhood and early adolescence also promote later antisocial behavior, but to a much lesser extent. Genetic causal factors are much more prominent for adult than for juvenile antisocial traits.

Mosquito control with the use of insecticides is faced with the challenges of insecticide resistance in disease vectors, community refusal, their high cost, operational difficulties, and environmental concern. In view of this, integrated vector control strategies with the use of larvivorous fishes such as Guppy (Poecilia reticulata) and Gambusia (G. affinis) as biological control agents were used in controlling mosquito breeding in different types of breeding places such as intradomestic containers, various types of wells, rice-fields, pools, ponds and elsewhere in malaria prone rural areas of central Gujarat. Attempts were also made to demonstrate composite fish culture in unused abandoned village ponds by culturing Guppy along with the food fishes such as Rohu (Labeo rohita), Catla (Catla catla) and Mrigal (Cirrhinus mrigala). Income generated from these ponds through sale of fishes was utilized for mosquito control and village development. The technology was later adopted by the villagers themselves and food fish culture was practised in 23 ponds which generated an income of Rs 1,02,50,992 between 1985 and 2008. The number of villages increased from 13 to 23 in 2008 and there was also gradual increase of income from Rs 3,66,245 in 1985-90 to Rs 55,06,127 in 2002-08 block. It is concluded that larvivorous fishes can be useful tool in controlling mosquito breeding in certain situations and their use along with composite fish culture may also generate income to make the programme self-sustainable.

To determine the prevalence and clinical association of myositis specific antibodies in an unselected group of patients with juvenile dermatomyositis (DM). The sera of 42 subjects, representing an unselected group of patients from a single center, with juvenile DM and 7 others with idiopathic inflammatory myopathy (IIM) were examined for the presence of myositis specific antibodies by immunodiffusion against calf thymus extract and immunoprecipitation with HeLa extract. Of the subjects with juvenile DM, only 2 had evidence of antibodies specific to myositis (anti-Mi2). Three other patients with juvenile DM had defined autoantibodies not usually considered to be specific to myositis. Two of the 3 subjects had anti-PM-Scl; both developed features of scleroderma after the juvenile DM remitted. The 5 subjects with defined autoantibodies did not differ clinically from the remainder of the subjects with the exception of the late development of scleroderma features in 2. Fourteen other subjects with juvenile DM had unidentified bands on immunoprecipitation, which may represent as yet undiscovered myositis specific antibodies. No myositis specific antibodies were detected in any of the 7 subjects with other IIM syndromes. Based on our findings, we do not recommend routine clinical testing for these antibodies in children with typical juvenile DM. Further study of the unidentified bands seen in our subjects may lead to better understanding of the clinical groupings and etiopathogenesis of childhood myositis.

Objective To examine clinical correlates of juvenile-onset OCD across the lifespan. Method Intake data collected from 257 consecutive participants with a juvenile-onset of OCD (20 children, 44 adolescents, and 193 adults) in a naturalistic study of the clinical course of OCD were examined. Participants and parents of juvenile participants completed a structured diagnostic interview, rater-administered severity measures, and self-report questionnaires. Results Children and adolescents (i.e. juveniles) shared similar features with the exception of age at onset and OCD symptom expression. Clinically meaningful differences between juvenile and adult participants were also found. Compared to adults, juveniles were more likely to be male, recall an earlier age at OCD onset, and have different lifetime comorbidity patterns. Conclusion Juvenile-onset OCD symptom expression is remarkably similar across the lifespan. However, findings also suggest clinically meaningful differences between juveniles and adults. Future work using a prospective design will improve our understanding of course patterns of juvenile-onset OCD. Significant Outcomes •Children were less likely than either adolescent or adults to report aggressive obsessions and mental rituals. •Males were overrepresented in the juvenile sample but gender was equally distributed in the adult sample •Compared to lifetime comorbidity patterns of adults, juveniles showed elevated rates of ADHD and lower rates of mood, substance use and eating disorders Limitations •The cross-sectional design with retrospective recall regarding course prior to study entry limits conclusions about the course of OCD. •The adult sample is limited to adults whose symptoms persisted into adulthood and therefore results cannot be generalized to all individuals with a juvenile-onset. •The small number of very young children (under age 10) may have limited power to detect differences among children and adolescents.

'Scared Straight' and other programmes involve organised visits to prison by juvenile delinquents or children at risk for criminal behavior. programmes are designed to deter participants from future offending through first-hand observation of prison life and interaction with adult inmates. These programmes remain in use world-wide despite studies and reviews questioning their effectiveness. To assess the effects of programmes comprising organised visits to prisons by juvenile delinquents (officially adjudicated or convicted by a juvenile court) or pre-delinquents (children in trouble but not officially adjudicated as delinquents), aimed at deterring them from criminal activity. Handsearching by the first author in identifying randomised field trials 1945-1993 relevant to criminology was augmented by structured searches of 16 electronic data bases, including the Campbell SPECTR database of trials and the Cochrane CCTR. Experts in the field were consulted and relevant citations were followed up. Studies that tested the effects of any program involving the organised visits of juvenile delinquents or children at-risk for delinquency to penal institutions were included. Studies that included overlapping samples of juvenile and young adults (e.g. ages 14-20) were included. We only considered studies that randomly or quasi-randomly (i.e. alternation) assigned participants to conditions. Each study had to have a no-treatment control condition with at least one outcome measure of "post-visit" criminal behavior. We report narratively on the nine eligible trials. We conducted one meta-analysis of post-intervention offending rates using official data. Information from other sources (e.g. self-report) was either missing from some studies or critical information was omitted (e.g. standard deviations). We examined the immediate post-treatment effects (i.e. "first-effects") by computing Odds Ratios (OR) for data on proportions of each group re-offending, and assumed both fixed and

2015-11-01

Nearly half a million inmates with mental health issues are housed in our country’s jails and prisons. The majority of juvenile justice-involved (JJI) youth have a history of behavioral health (mental health or substance use) problems. Multiple studies estimate that between 65% to 75% of juvenile justice-involved youth have at least one behavioral health disorder, and 20% to 30% report suffering from a serious behavioral disorder. With so many juveniles with behavioral health issues entering a system that was not designed to provide comprehensive treatment, communities are reevaluating their approach to juvenile justice. This article describes the origins and the results of Ohio’s Behavioral Health Juvenile Justice Initiative (BHJJ), a diversion program for juvenile justice-involved youth with behavioral health issues. The authors also discuss the key components of program success, offer advice to other jurisdictions considering implementing similar programming, and identify ways to take diversion programs to scale.

2016-12-01

The goal of the study was to evaluate the repair of chondral lesions treated with combined autologous adult/allogenic juvenile cartilage fragments, compared with isolated adult and isolated juvenile cartilage fragments. Fifty-eight adult (>16 week old) and five juvenile (<6 week old) New Zealand White female rabbits were used. A large osteochondral defect was created in the center of the femoral trochlea of adult rabbits. The rabbits were divided in four groups: Group 1 = untreated defects (controls); Group 2 = adult cartilage fragments; Group 3 = juvenile cartilage fragments; and Group 4 = adult + juvenile cartilage fragments. Killings were performed at 3 and 6 months. The defects were evaluated with ICRS macroscopic score, modified O'Driscoll score, and Collagen type II immunostaining. At 3 months, Group 4 performed better than Group 1, in terms of modified O'Driscoll score (p = 0.001) and Collagen type II immunostaining (p = 0.015). At 6 months, Group 4 showed higher modified O'Driscoll score (p = 0.003) and Collagen type II immunostaining score (p < 0.001) than Group 1. Histologically, also Group 3 performed better than Group 1 (p = 0.03), and Group 4 performed better than Group 2 (p = 0.004). Mixing adult and juvenile cartilage fragments improved cartilage repair in a rabbit model. In the clinical setting, a new "one-stage" procedure combining the two cartilage sources can be hypothesized, with the advantages of improved chondral repair and large defect coverage, because of the use of an off-the-shelf juvenile allograft. Further studies on larger animals and clinical trials are required to confirm these results.

Juvenile delinquency treatment and prevention: a literature review.

In the last three decades there has been ample research to demonstrate that instituting Multisystemic Therapy for serious juvenile offenders, keeping them in the community with intensive intervention, can significantly reduce recidivism. When there is recidivism, it is less severe than in released incarcerated juveniles. Multisystemic Therapy provides 24 h available parental guidance, family therapy, individual therapy, group therapy, educational support and quite importantly a change of peer group. In New York City, there is the new mandate through the Juvenile Justice Initiative to implement interventions to keep juvenile offenders in the community rather than sending them to be incarcerated. However, this paper aims to examine how teaching prosocial values in early childhood can reduce the incidence of first-time juvenile delinquency. Programs such as the Perry School Project will be discussed to demonstrate that although somewhat expensive, these innovative programs nonetheless are quite cost-effective as the cost to society of adjudication, incarceration and victim damages are significantly greater. Along with teaching prosocial 0020 values, there has been renewed interest in early identification of youth at risk for developing Antisocial Personality Disorder. An update is given on the status of both promising approaches in early intervention to prevent serious juvenile delinquency and hence adult criminality.

Accurate aging of juvenile salmonids using fork lengths

Juvenile salmon life history strategies, survival, and habitat interactions may vary by age cohort. However, aging individual juvenile fish using scale reading is time consuming and can be error prone. Fork length data are routinely measured while sampling juvenile salmonids. We explore the performance of aging juvenile fish based solely on fork length data, using finite Gaussian mixture models to describe multimodal size distributions and estimate optimal age-discriminating length thresholds. Fork length-based ages are compared against a validation set of juvenile coho salmon, Oncorynchus kisutch, aged by scales. Results for juvenile coho salmon indicate greater than 95% accuracy can be achieved by aging fish using length thresholds estimated from mixture models. Highest accuracy is achieved when aged fish are compared to length thresholds generated from samples from the same drainage, time of year, and habitat type (lentic versus lotic), although relatively high aging accuracy can still be achieved when thresholds are extrapolated to fish from populations in different years or drainages. Fork length-based aging thresholds are applicable for taxa for which multiple age cohorts coexist sympatrically. Where applicable, the method of aging individual fish is relatively quick to implement and can avoid ager interpretation bias common in scale-based aging.

A new mass mortality of juvenile Protoceratops and size-segregated aggregation behaviour in juvenile non-avian dinosaurs.

Monodominant bonebeds are a relatively common occurrence for non-avian dinosaurs, and have been used to infer associative, and potentially genuinely social, behavior. Previously known assemblages are characterized as either mixed size-classes (juvenile and adult-sized specimens together) or single size-classes of individuals (only juveniles or only adult-sized individuals within the assemblage). In the latter case, it is generally unknown if these kinds of size-segregated aggregations characterize only a particular size stage or represent aggregations that happened at all size stages. Ceratopsians ("horned dinosaurs") are known from both types of assemblages. Here we describe a new specimen of the ceratopsian dinosaur Protoceratops andrewsi, Granger and Gregory 1923 from Mongolia representing an aggregation of four mid-sized juvenile animals. In conjunction with existing specimens of groups of P. andrewsi that includes size-clustered aggregations of young juveniles and adult-sized specimens, this new material provides evidence for some degree of size-clustered aggregation behaviour in Protoceratops throughout ontogeny. This continuity of size-segregated (and presumably age-clustered) aggregation is previously undocumented in non-avian dinosaurs. The juvenile group fills a key gap in the available information on aggregations in younger ceratopsians. Although we support the general hypothesis that many non-avian dinosaurs were gregarious and even social animals, we caution that evidence for sociality has been overstated and advocate a more conservative interpretation of some data of 'sociality' in dinosaurs.

Do juveniles help or hinder? Influence of juvenile offspring on maternal behavior and reproductive outcomes in wild chimpanzees (Pan troglodytes).

Compared to great apes, humans maintain a relatively rapid reproductive pace despite long periods of dependency. This seemingly contradictory set of traits is made possible by weaning offspring before nutritional independence and alloparents who help provide care. In traditional societies, this help may be provided to mothers in part by their juvenile offspring who carry, supervise, or provision younger siblings. In contrast to humans, chimpanzees (Pan troglodytes) are nutritionally independent after weaning, yet juveniles continue to travel with their mother and younger sibling for an additional 4-5 years. This continued association could be costly to the mother if she continues to invest in weaned offspring. Alternately, while juvenile chimpanzees do not typically provision younger siblings, their presence and social interaction with infants may allow mothers to focus on other tasks. In this study, we investigate the costs and benefits to mothers of continued association with juveniles in wild chimpanzees. Using 26 years of long-term behavioral data we examined how maternal activity budgets varied based on the presence of a dependent juvenile offspring. We found that continued social interaction between mothers and juveniles does not influence the mother's time allocated to interacting with the younger infant, her feeding, resting, or travel time, or time socializing with other community members. Instead, mothers may benefit from the additional social interaction and/or relationship with their older offspring. Using 45 years of demographic data we found that those offspring who had an older sibling tended to be more likely to survive each year from birth to 8 years than those without an older sibling. Additionally, interbirth intervals were more likely to end when the female had an older offspring present. A mutually beneficial mother-juvenile dynamic in great apes provides insight into continued association between mothers and offspring after nutritional

Participation in sports activities is very popular among adolescents, and is frequently encouraged among youth. Many psychosocial health benefits in youth are attributed to sports participation, but to what extent this positive influence holds for juvenile delinquency is still not clear on both the theoretical and empirical level. There is much controversy on whether sports participation should be perceived as a protective or a risk factor for the development of juvenile delinquency. A multilevel meta-analysis of 51 published and unpublished studies, with 48 independent samples containing 431 effect sizes and N = 132,366 adolescents, was conducted to examine the relationship between sports participation and juvenile delinquency and possible moderating factors of this association. The results showed that there is no overall significant association between sports participation and juvenile delinquency, indicating that adolescent athletes are neither more nor less delinquent than non-athletes. Some study, sample and sports characteristics significantly moderated the relationship between sports participation and juvenile delinquency. However, this moderating influence was modest. Implications for theory and practice concerning the use of sports to prevent juvenile delinquency are discussed.

In contrast to adult rodents, juvenile rodents fail to show relapse following extinction of conditioned fear. Using different retrograde tracers injected into the infralimbic cortex (IL) and the ventral hippocampus (vHPC) in conjunction with c-Fos and parvalbumin (PV) immunochemistry, we investigated the neurocircuitry of extinction in juvenile and adult rats. Regardless of fear extinction or retrieval, juvenile rats had more c-Fos+ neurons in the basolateral amygdala (BLA) compared to adults, and showed a higher proportion of c-Fos+ IL-projecting neurons. Adult rats had more activated vHPC-projecting BLA neurons following extinction compared to retrieval, a difference not observed in juvenile rats. The number of activated vHPC- or IL-projecting BLA neurons was significantly correlated with freezing levels in adult, but not juvenile, rats. We also identified neurons in the BLA that simultaneously project to the IL and vHPC activated in the retrieval groups at both ages. This study provides novel insight into the neural process underlying extinction, especially in the juvenile period. Copyright © 2018 Elsevier B.V. All rights reserved.

Juvenile bovine patients who present with clinical signs of lameness are commonly evaluated using radiographic techniques both within a hospital setting and in a farm environment. The radiographic development of the juvenile bovine skeleton is currently poorly documented. In this study, the limbs of four heifer calves were sequentially radiographed to assess development of the juvenile bovine appendicular skeleton in the first 12 months of life. Images were acquired at three weeks, three months, six months, nine months and one year of age. The normal radiographic anatomy of the fore limbs and hindlimbs and the changes over the first 12 months are described. The majority of physes remain open throughout this period, with the exception of the proximal physes of the proximal and middle phalanges, the proximal radial physis, and the proximal humeral physis which close radiographically between 9 months and 12 months of age, and fusion of the fourth and central tarsal bones occurs between 9 months and 12 months of age. The results of this study may aid in differentiating normal and abnormal anatomy in the juvenile bovine limb. British Veterinary Association.

Juvenile hormone activity in Dysdercus cingulatus Fabr by juvenile hormone esterase inhibitor, OTFP.

Elayidam, U Gayathri; Muraleedharan, D

2007-10-01

Application of juvenile hormone esterase inhibitor 3-octylthio-1,1,1- trifluropropan-2-one (OTFP) to 5th instar nymphs and virgin females of D. cingulatus revealed the profound role played by juvenile hormone esterase (JHE) in metamorphosis and reproduction. The ability of OTFP to cause delay and the formation of malformed nymphs, suggests that inhibition of JHE in vivo maintains a higher than normal hemolymph JH titer. It is obvious that OTFP does inhibit in vivo JHE activity in late instar nymphs. Further, the application of JHE inhibitor, OTFP to virgin females demonstrates that substituted trifluropropanones can indirectly stimulate egg development by inhibiting JHE activity in virgin females.

Juvenile fibromyalgia (FM) is characterized by chronic musculoskeletal pain and marked reduction in physical activity. Despite recommendations for exercise to manage juvenile FM pain, exercise adherence is poor. Because of pain and activity avoidance, adolescents with juvenile FM are at risk for altered joint mechanics that may make them susceptible to increased pain and reduced tolerance for exercise. The primary aim of this study was to assess functional deficits in patients with juvenile FM compared to healthy controls using objective biomechanical assessment. Female adolescent patients with juvenile FM (n = 17) and healthy controls (n = 14) completed biomechanical assessments, including gait analysis and tests of lower extremity strength (isokinetic knee extension/flexion and hip abduction) and functional performance (drop vertical jump test) along with self-reported measures of disability (Functional Disability Inventory), pain intensity, depressive symptoms (Children's Depression Inventory), and fear of movement (Tampa Scale of Kinesiophobia). Patients with juvenile FM demonstrated mild deficiencies in walking gait and functional performance (P < 0.05 for both) and significantly lower left knee extension and flexion strength (18-22% deficit) and bilateral hip abduction strength (34-38%) compared with healthy controls (P < 0.008 for all). Patients with juvenile FM reported significantly higher functional disability, pain intensity, depressive symptoms, and fear of movement relative to controls (P < 0.01 for all). This study showed that adolescents with juvenile FM exhibited objective alterations in biomechanics and self-reported fear of movement that may have reinforced their activity avoidance. Interventions for juvenile FM should include a focus on correcting functional deficits and instilling greater confidence in adolescents with juvenile FM to engage in exercise to improve functional outcomes.

Yolo Bypass Juvenile Salmon Utilization Study 2016—Summary of acoustically tagged juvenile salmon and study fish release, Sacramento River, California

USGS Publications Warehouse

Liedtke, Theresa L.; Hurst, William R.

2017-09-12

The Yolo Bypass is a flood control bypass in Sacramento Valley, California. Flood plain habitats may be used for juvenile salmon rearing, however, the potential value of such habitats can be difficult to evaluate because of the intermittent nature of inundation events. The Yolo Bypass Juvenile Salmon Utilization Study (YBUS) used acoustic telemetry to evaluate the movements and survival of juvenile salmon adjacent to and within the Yolo Bypass during the winter of 2016. This report presents numbers, size data, and release data (times, dates, and locations) for the 1,197 acoustically tagged juvenile salmon released for the YBUS from February 21 to March 18, 2016. Detailed descriptions of the surgical implantation of transmitters are also presented. These data are presented to support the collaborative, interagency analysis and reporting of the study findings.

Prevalence of traumatic brain injury in juvenile offenders: a meta-analysis.

PubMed

Farrer, Thomas J; Frost, R Brock; Hedges, Dawson W

2013-01-01

Studies of traumatic brain injury (TBI) among adult populations demonstrate that such injuries can lead to aggressive behaviors. Related findings suggest that incarcerated individuals have high rates of brain injuries. Such studies suggest that traumatic brain injury may be related to the etiology and recidivism of criminal behavior. Relatively few studies have examined the prevalence of TBI using a delinquent juvenile sample. In order to assess the relationship between TBI and juvenile offender status, the current study used meta-analytic techniques to examine the odds of having a TBI among juvenile offenders. Across 9 studies, we found that approximately 30% of juvenile offenders have sustained a previous brain injury. Across 5 studies that used a control group, a calculated summary odds ratio of 3.37 suggests that juvenile offenders are significantly more likely to have a TBI compared to controls. Results suggest that the rate of TBIs within the juvenile offender population is significant and that there may be a relationship between TBIs and juvenile criminal behavior.

Juvenile xanthogranuloma of the corneoscleral limbus.

PubMed

Yanoff, M; Perry, H D

1995-07-01

Juvenile xanthogranuloma is a rare and usually benign skin disease of unknown cause that occurs in infants and young children. We studied a case of juvenile xanthogranuloma of the corneoscleral limbus in a 17-year-old black boy, who presented with a 5-month history of a lump in the right eye. The lesion extended from the superior limbus, fanning out as it proceeded posteriorly for 6 mm with a width of 9 mm and a height of 2 to 3 mm. This yellow-orange mass was vascular and firmly fixed to the underlying tissue. The lesion was diagnosed as a dermoid and observed for 7 months without documented growth before an uneventful excisional biopsy was performed. The pathologic diagnosis showed the characteristic picture of juvenile xanthogranuloma with numerous Touton giant cells. Lipid stains provided further confirmation.

1991-01-01

We studied home range and movements of 15 radio-marked, juvenile Puerto Rican parrots (Amazona vittata) fledging from wild nests during summer and fall, 1985-87. When juvenile parrots remained in the nest valley, home ranges during 1986 (.hivin.x = 32 .+-. 10 [SE] ha, n = 4) were larger (P = 0.0079) than during 1987 (.hivin.x = 13 .+-. 6 ha, n = 5). After radio-marked parrots integrated into adult flocks, home ranges during 1986 (.hivin.x = 1,075 .+-. 135 ha, n = 3) were similar (P = 0.10) to 1987 (.hivin.x = 416 .+-. 62 ha, n = 2). Juvenile parrots restricted their movements to nest valleys an average of 58 .+-. 29 days following fledging. After joining adult flocks, juvenile parrots routinely flew between the east and west slopes of the Luquillo Mountains but did not exhibit a seaonal pattern of movement. We recommend that captive-raised, juvenile parrots used in release programs be .gtoreq. 5 months old to ensure they are mature enough to integrate into wild flocks.

Bilateral, independent juvenile nasopharyngeal angiofibroma: case report.

PubMed

Mørkenborg, M-L; Frendø, M; Stavngaard, T; Von Buchwald, C

2015-10-01

Juvenile nasopharyngeal angiofibroma is a benign, vascular tumour that primarily occurs in adolescent males. Despite its benign nature, aggressive growth patterns can cause potential life-threatening complications. Juvenile nasopharyngeal angiofibroma is normally unilateral, originating from the sphenopalatine artery, but bilateral symptoms can occur if a large tumour extends to the contralateral side of the nasopharynx. This paper presents the first reported case of true bilateral extensive juvenile nasopharyngeal angiofibroma involving clinically challenging pre-surgical planning and surgical strategy. A 21-year-old male presented with increasing bilateral nasal obstruction and discharge. Examination revealed tumours bilaterally and imaging demonstrated non-contiguous tumours. Pre-operative angiography showed strictly ipsilateral vascular supplies requiring bilateral embolisation. Radical removal performed as one-step, computer-assisted functional endoscopic sinus surgery was performed. The follow-up period was uncomplicated. This case illustrates the importance of suspecting bilateral juvenile nasopharyngeal angiofibroma in patients presenting with bilateral symptoms. Our management, including successful pre-operative planning, enabled one-step total removal of both tumours and rapid patient recovery.

2014-12-01

Probation is the most common disposition for adjudicated youth, but little is known about which specific requirements are commonly imposed on juveniles, the requirements with which juveniles most often fail to comply, and how certain youth characteristics and/or imposed requirements might relate to probation noncompliance. An investigation of 120 archived files of youth represented by an urban public defender's office identified 29 probation requirements imposed on youth and 18 requirements with which youth commonly failed to comply. Results revealed that 52% of youth failed to comply with at least one probation requirement; prior probation noncompliance and race were both significantly associated with noncompliance in the examined probation disposition. In addition, the probability of probation noncompliance was significantly higher when youth received either of two substance-related probation requirements: drug tests or drug and alcohol counseling. Such results may prompt further investigation of juvenile probation-related predictors, identify areas of need for clinical service provision to foster successful completion of probation requirements, and help identify areas of potential biases among juvenile court personnel.

Phototaxis of larval and juvenile northern pike

USGS Publications Warehouse

Zigler, S.J.; Dewey, M.R.

1995-01-01

Age- Phi northern pike Esox lucius prefer vegetated habitats that are difficult to sample with standard towed gears. Light traps can be effective for sampling larval fishes in dense vegetation, given positive phototaxis of fish. We evaluated the phototactic response of young northern pike by comparing the catches of larvae and juveniles obtained with plexiglass traps deployed with a chemical light stick versus traps deployed without a light source (controls) in a laboratory raceway and in a vegetated pond. In the laboratory tests, catches of protolarvae and mesolarvae in lighted traps were 11-35 times greater than catches in control traps. The catches of juvenile northern pike in field and laboratory experiments were 3-15 times greater in lighted traps than in control traps, even though the maximum body width of the larger juveniles was similar to the width of the entrance slots of the traps (5 mm). Larval and juvenile northern pike were photopositive; thus, light traps should effectively sample age-0 northern pike for at least 6 weeks after hatching.

2014-01-01

The in-reservoir movements and dam passage of individual juvenile Chinook salmon (Oncorhynchus tshawytscha) and juvenile steelhead (Oncorhynchus mykiss) were studied at Detroit Reservoir and Dam, near Detroit, Oregon, during 2012 and 2013. The goal of the study was to provide data to inform decisions about future downstream passage alternatives and factors affecting downstream passage rates with the existing dam configuration. In 2012, 468 juvenile Chinook salmon and 200 juvenile steelhead were tagged and released during a 3-month period in the spring, and another 514 juvenile Chinook salmon were tagged and released during a 3-month period in the fall. The fish were surgically implanted with a small acoustic transmitter with an expected life of about 3 months and a passive integrated transponder tag with an indefinite life, and were released into the two main tributaries several kilometers upstream of the reservoir. Juvenile Chinook salmon migrated from the release sites to the reservoir in a greater proportion than juvenile steelhead, but once in the reservoir, juvenile steelhead migrated to the forebay faster and had a higher dam passage rate than juvenile Chinook salmon. The routes available for passing water and fish varied throughout the year, with low reservoir elevations in winter and high reservoir elevations in summer in accordance with the flood-control purpose of the dam. Most dam passage was through the spillway during the spring and summer, when the reservoir elevation was high and the spillway and powerhouse were the most common routes in operation, and via the powerhouse during the fall and winter period, when the reservoir elevation was low and the regulating outlet and powerhouse were the most common routes in operation. Few tagged fish passed when the powerhouse was the only route in operation. Dam passage rates during the spring and summer were greatest at night, increased with dam discharge, and were greater when water was passed freely over the

Race and the Fragility of the Legal Distinction between Juveniles and Adults

Legal precedent establishes juvenile offenders as inherently less culpable than adult offenders and thus protects juveniles from the most severe of punishments. But how fragile might these protections be? In the present study, simply bringing to mind a Black (vs. White) juvenile offender led participants to view juveniles in general as significantly more similar to adults in their inherent culpability and to express more support for severe sentencing. Indeed, these differences in participants’ perceptions of this foundational legal precedent distinguishing between juveniles and adults accounted for their greater support for severe punishment. These results highlight the fragility of protections for juveniles when race is in play. Furthermore, we suggest that this fragility may have broad implications for how juveniles are seen and treated in the criminal justice system. PMID:22649496

Most child pornography is distributed online. It is estimated that 3% to 15% of child pornography consumers are juveniles. The present study analyzed a consecutive sample of 54 male juveniles convicted of the possession of child pornography. Demographic characteristics, criminal history, and subsequent offending were assessed from criminal files and official reports. Juvenile possessors of child pornography were compared to three different groups of juveniles: Juvenile possessors of other illegal pornography (n = 42), juveniles who committed a sexual contact offense against a child (n = 64), and juveniles who committed a sexual contact offense against a peer or adult (n = 104). Juvenile possessors of child pornography were found to have downloaded the illegal material more frequently and over a longer time period than juvenile possessors of other illegal pornography. Furthermore, juvenile possessors of child pornography differed from juveniles who had committed a sexual contact offense in terms of demographics and showed fewer previous and subsequent offending than juveniles who sexually offended against a peer or adult. We conclude that juvenile possessors of child pornography need a specific target intervention focusing on dysfunctional Internet use and sexually deviant arousal. © The Author(s) 2013.

Maternal Touch Moderates Sex Differences in Juvenile Social Play Behavior

PubMed Central

Edelmann, Michelle N.; Demers, Catherine H.; Auger, Anthony P.

2013-01-01

Additional somatosensory contact of preterm human infants improves a variety of developmental assessment scores, but less is known about its lasting consequences. In rodents, maternal contact may influence the programming of juvenile social play behavior. Therefore, we used a paradigm where we can control the levels of somatosensory contact associated with maternal care. We find that additional somatosensory contact of offspring can have lasting consequences on juvenile social play behavior in a sex-dependent manner. Specifically, additional somatosensory stimuli reduced male social play behavior, but did not change female play behavior. We then examined if this additional infant contact altered some neurobiological substrates associated with play within the juvenile amygdala. Control males had lower levels of 5HT2a receptor mRNA levels contrasted to females; however, similar to its sex-dependent effect on juvenile social play, males that received additional somatosensory contact had higher serotonin 5HT2a receptor mRNA levels than control males. No difference was found in females. As serotonin signaling typically opposes juvenile play behavior, these data suggest that maternal touch can program lasting differences in juvenile social play and 5HT2a receptors mRNA levels within the juvenile amygdala.

The effect of medical cannabis laws on juvenile cannabis use.

PubMed

Stolzenberg, Lisa; D'Alessio, Stewart J; Dariano, Dustin

2016-01-01

A number of states in the United States legally allow the use of cannabis as a medical therapy to treat an illness or to alleviate symptoms. Concern persists as to whether these types of laws are increasing juvenile recreational cannabis use. It is also plausible that medical cannabis laws engender an escalation of illicit non-cannabis drug use among juveniles because cannabis is frequently considered to be a gateway drug. This study uses longitudinal data drawn from the National Survey on Drug Use and Health for the 50 U.S. states and a cross-sectional pooled-time series research design to investigate the effect of medical cannabis laws on juvenile cannabis use and on juvenile non-cannabis illicit drug use. Our study period encompasses five measurement periods calibrated in two-year intervals (2002-2003 to 2010-2011). This research design is advantageous in that it affords us the ability not only to assess the effect of the implementation of medical cannabis laws on juvenile drug use, but also to consider other state-specific factors that may explain variation in drug use that cannot be accounted for using a single time series. Findings show that medical cannabis laws amplify recreational juvenile cannabis use. Other salient predictors of juvenile cannabis use at the state-level of analysis include perceived availability of cannabis, percent of juveniles skipping school, severity of perceived punishment for cannabis possession, alcohol consumption, percent of respondents with a father residing in household, and percent of families in the state receiving public assistance. There is little empirical evidence to support the view that medical cannabis laws affect juveniles' use of illicit non-cannabis drugs. Based on our findings, it seems reasonable to speculate that medical cannabis laws amplify juveniles' use of cannabis by allaying the social stigma associated with recreational cannabis use and by placating the fear that cannabis use could potentially result in a

Juvenile Radio-Tag Study: Lower Granite Dam, 1985 Annual Report.

DOE Office of Scientific and Technical Information (OSTI.GOV)

Stuehrenberg, Lowell C.

The concept of using mass releases of juvenile radio tags represents a new and potentially powerful research tool that could be effectively applied to juvenile salmonid passage problems at dams on the Columbia and Snake Rivers. A system of detector antennas, strategically located, would automatically detect and record individually tagged juvenile salmonids as they pass through the spillway, powerhouse, bypass system, or tailrace areas below the dam. Accurate measurements of spill effectiveness, fish guiding efficiency (FGE), collection efficiency (CE), spillway survival, powerhouse survival, and bypass survival would be possible without handling large numbers of unmarked fish. A prototype juvenile radio-tagmore » system was developed and tested by the National Marine Fisheries Service (NMFS) and Bonneville Power Administration (BPA) at John Day Dam and at Lower Granite Dam. This report summarizes research to: (1) evaluate the effectiveness of the prototype juvenile radio-tag system in a field situation and (2) to test the basic assumptions inherent in using the juvenile radio tag as a research tool.« less

Distribution of trace elements in the aquatic ecosystem of the Thigithe river and the fish Labeo victorianus in Tanzania and possible risks for human consumption.

2016-03-15

The aim of the present study was to assess the distribution of trace elements in the aquatic ecosystem of the Thigithe river. Samples of surface water, sediment and fish were collected up- and downstream of the North Mara Gold Mine (Tanzania) and following trace elements were analysed: As, Cd, Co, Cr, Cu, Hg, Ni, Pb and Zn. Trace element concentrations in surface water were below or near the detection limit. Regarding the sediments, relative high concentrations of arsenic at all sites and high levels of mercury at a site downstream of the mine where artisanal mining is performed were observed. Trace element concentrations in Ningu fish tissues (Labeo victorianus) were comparable to slightly higher than levels in fishes from unpolluted environments. For none of the measured human health risk by consumption of fish from the Thigithe river is expected when the Tanzanian average amount of 17 g/day is consumed. However, for Hg and As the advised maximum daily consumption of Ningu fish was lower than 100g. As a result fishermen and people living along the shores of the river consuming more fish than the average Tanzanian fish consumption set by the FAO (2005) are possibly at risk.

Corporal and capital punishment of juveniles.

PubMed

Frazier, H C

1990-01-01

There is a previously unobserved connection between corporal punishment of public school children and capital punishment of juveniles. Both are barometers of acceptable levels of violent punishment and their elimination is a hallmark of a maturing and decent society. Within a majority of the eighteen states where school authorities most frequently strike children are housed 25 of the nation's 28 juvenile death row inmates. On average, the homicide rates of these jurisdictions are two and a half times greater than those that have abolished both state-sanctioned corporal and capital punishment or limit death sentences to those age eighteen and older at the time of their crime(s). Most of the eighteen state abolitions of corporal punishment occurred in the 1980's. The US Supreme Court has ruled both corporal and capital punishment of juveniles constitutional. Additional state legislative abolition of both is anticipated in the 1990s.

Modern management of juvenile recurrent parotitis.

To evaluate modern diagnostic and therapeutic management of juvenile recurrent parotitis, and to show the benefits of operative sialoendoscopy on the basis of our experience in 14 patients and the results of others. Ultrasonography is sensitive in detecting the pathological features of juvenile recurrent parotitis. Interventional sialoendoscopy is a safe and effective method of treating the disease. In our case series, after a mean follow-up time of 30 months only 5 patients experienced recurrence of symptoms, with a mean symptom-free period of 20 months. The use of modern, minimally invasive diagnostic tools such as colour Doppler ultrasonography, magnetic resonance sialography and sialoendoscopy represents a new frontier in the management of juvenile recurrent parotitis. Operative sialoendoscopy also has the important therapeutic benefit of reducing the number of recurrences of acute episodes of parotitis, thus giving patients a better quality of life until puberty.

Pityriasis rubra pilaris (PRP) is a papulosquamous dermatosis uncommon in juveniles. Large-scale studies are limited, especially from Asian countries. We sought to analyze the clinical manifestations of juvenile PRP in Taiwanese patients and compare them with reported series in the literature. The diagnosis of juvenile PRP was made based on clinical-histopathologic correlation. The therapeutic response and disease course were followed up by re-examination of the patients or by telephone. A total of 47 patients were identified, with histopathologic confirmation of the clinical diagnosis of juvenile PRP in 28 cases. A preponderance of Griffiths' type IV PRP (85.7%) rather than type III PRP (14.3%) was found. Palmoplantar hyperkeratosis appeared to be a cardinal feature. In patients with type IV PRP, skin lesions in areas other than the elbows/knees and palms/soles were common. Treatment with systemic acitretin in 6 patients failed to effect a dose- or time-dependent improvement. In contrast with other studies, two thirds of our patients with type III and IV juvenile PRP had a protracted course lasting more than 3 years. This study was a retrospective review. Patient compliance with treatment was frequently poor. Type IV juvenile PRP predominated but our cases showed a wider distribution of skin lesions than is typically described. When children present with an acute onset of diffuse palmoplantar hyperkeratosis, a diagnosis of juvenile PRP should be considered. Because of the divergent clinical manifestations of juvenile PRP in different populations, there is a need to modify and re-evaluate classification systems based on regional differences.

Sex differences in play behavior in juvenile tufted capuchin monkeys (Cebus apella).

PubMed

Paukner, Annika; Suomi, Stephen J

2008-10-01

According to the motor training hypothesis, play behavior in juvenile primates improves motor skills that are required in later adult life. Sex differences in juvenile play behavior can therefore be expected when adult animals assume distinct sexually dimorphic roles. Tufted capuchin monkeys show sexually dimorphic levels of physical antagonism in both inter- and intra-group encounters. Accordingly, it can be predicted that juvenile capuchins also show sex differences in social play behavior. To test this hypothesis, the play behavior of nine juvenile and two infant capuchins was examined. As predicted, juvenile males showed significantly higher levels of social play (wrestle, chase) than juvenile females, but no differences were found in nonsocial play (arboreal, object). Levels of infant play behavior were comparable to that of juveniles. These results lend support to the motor training hypothesis and highlight the need for more detailed investigations of individual differences in play behavior.

Parental Low Self-Control, Family Environments, and Juvenile Delinquency.

PubMed

Meldrum, Ryan C; Connolly, George M; Flexon, Jamie; Guerette, Rob T

2016-10-01

Research consistently finds that low self-control is significantly correlated with delinquency. Only recently, however, have researchers started to examine associations between parental low self-control, family environments, and child antisocial behavior. Adding to this emerging area of research, the current study examines associations between parental low self-control, aspects of the family environment, and officially recoded juvenile delinquency among a sample (N = 101) of juveniles processed through a juvenile justice assessment facility located in the Southeastern United States. Furthermore, it considers whether aspects of family environments, particularly family cohesion, family conflict, and parental efficacy, mediate the influence of parental low self-control on delinquency. The results of a series of analyses indicate that parental low self-control is correlated with various aspects of family environments and juvenile delinquency, and that the association between parental low self-control and juvenile delinquency is mediated by family environments. Supplementary analyses also suggest that the association between parental low self-control and the family environment may be reciprocal. © The Author(s) 2015.

Temperament of juvenile delinquents with history of substance abuse.

Chang, Hsueh-Ling; Chen, Sue-Huei; Huang, Chien

2007-01-01

The etiological factors and interrelations of juvenile delinquents, with psychiatric morbidity and substance abuse have been continuously debated. Cloninger's Tridimensional Theory of Temperament has been reported to predict patterns of substance abuse and comorbidity. In the current study, we aimed to examine the usability of the theory in predicting juvenile delinquency and substance abuse. Sixty consecutive and newly incarcerated male delinquents with history of substance abuse were recruited from a juvenile correctional facility in northwestern Taiwan from January 2002 through December 2003. All subjects were assessed of their temperament, behavioral problems, and psychiatric disorders on an individual base. The juvenile delinquent subjects with childhood history of attention deficit and hyperactivity disorder (ADHD) were significantly younger, consumed less betel nuts, and had more siblings with history of drug abuse. Consistent with the results of Cloninger's studies, novelty seeking positively correlated to the amount of substance abuse, while harm avoidance inversely correlated in juvenile delinquents. Endemic trend of choice of substance abuse needs to be taken into consideration in future research projects.

The future of criminal violence: juveniles tried as adults.

PubMed

Kirkish, P; Sreenivasan, S; Welsh, R; Van Gorp, W; Eth, S; Shoptaw, S; Ling, W

2000-01-01

Juveniles tried as adults (JTA) represent a select and small subsample of juvenile offenders. This study seeks to provide a profile of habitually violent JTAs transferred to the adult penal system and to compare them with their adult counterparts. Twenty-nine incarcerated violent male juveniles tried as adults were compared with a sample of 27 incarcerated violent male offenders across demographic, neuropsychological, criminal history, psychopathy, and substance abuse variables. The JTAs were characterized by a high rate of gang membership (96%), substance abuse (alcohol, marijuana, and phenylcyclidene), and use of guns. In the juvenile sample, 65 percent used guns in violence not leading to arrest, and 93 percent used guns in a violent crime leading to arrest. Juvenile offenders were similar to their adult counterparts in patterns of criminality, although adult offenders had higher psychopathy scores. Both groups revealed generally intact neuropsychological functioning with the exception of a higher rate of perseverative responses in the adult sample. The results are discussed in terms of the implication of the degree of violence in a young offender population.

Brain sex differences and the organisation of juvenile social play behaviour.

PubMed

Auger, A P; Olesen, K M

2009-06-01

Juvenile social play behaviour is one of the earliest forms of non-mother directed social behaviour in rodents. Juvenile social play behaviour is sexually dimorphic, with males exhibiting higher levels compared to females, making it a useful model to study both social development and sexual differentiation of the brain. As with most sexually dimorphic behaviour, juvenile play behaviour is organised by neonatal steroid hormone exposure. The developmental organisation of juvenile play behaviour also appears to be influenced by the early maternal environment. This review will focus briefly on why and how rats play, some brain regions controlling play behaviour, and how neurotransmitters and the social environment converge within the developing brain to influence sexual differentiation of juvenile play behaviour.

Evidence of separate subgroups of juvenile southern bluefin tuna.

Chambers, Mark S; Sidhu, Leesa A; O'Neill, Ben; Sibanda, Nokuthaba

2017-11-01

Archival tagging studies of southern bluefin tuna (SBT , Thunnus maccoyii ) have revealed that juveniles residing in the Great Australian Bight (GAB) over the austral summer undertake seasonal cyclic migrations to the southeast Indian Ocean and the Tasman Sea during winter. However, there remains disagreement about the extent of mixing between juvenile SBT regularly caught by longline fleets south of Africa and those observed in the GAB. Some researchers have argued that archival tag recoveries indicate most juveniles reside in the GAB over the austral summer. Others have suggested that recoveries of conventional and archival tags are better explained by a juvenile population consisting of separate groups on the eastern and western sides of the Indian Ocean with limited intermixing. We present analyses of catch and tag recovery data and re-examine archival tagging studies. The evidence provided strongly favors the hypothesis of separate juvenile subgroups, or contingents, with limited intermixing. We draw some tentative conclusions about the nature of the putative contingents and discuss some implications of these findings for the interpretation of existing datasets and future research priorities. We also provide the first evidence that the migration choices of juveniles that summer in the GAB are influenced by fidelity to winter feeding grounds and suggest this helps explain the collapse of the surface fishery off New South Wales in the 1980s.

[Cerebellar, pulmonary and cutaneous localizations of juvenile xanthogranuloma].

Cauro, F; Houtteville, J P; Mesnil, J L; Guarnieri, J

2002-03-01

Juvenile xanthogranuloma is one of the most common non-langerhan cell histiocytoses in children. Usually cutaneous, there are disseminated forms. However, neurological localizations remain exceptional. We report the case of a cerebellar localization, associated with cutaneous and pulmonary lesions in a 13-month old child. Surgical treatment of the cerebellar lesion was associated with vinblastin chemotherapy, that led to total regression of the cutaneous and pulmonary lesions, neurological stabilization, without recurrence on the control IRM, after a period of 7 years. This is the second reported case of histologically documented cerebellar juvenile xanthogranuloma. In the event of cutaneous juvenile xanthogranuloma, the neurological examination must be attentive and supplemented, in case of any suspicion, by medical imaging. We believe that surgical treatment of neurological juvenile xanthogranuloma is necessary, in the event of symptomatic lesions and accessible to surgery. No consensus has been reached on subsequent treatments (radiotherapy, chemotherapy) and must be discussed according to the clinical profile and data in the literature.

American juvenile justice system: history in the making.

PubMed

Meng, Aaron; Segal, Roland; Boden, Eric

2013-01-01

The original theory behind separating juvenile offenders from adult offenders was to provide care and direction for youngsters instead of isolation and punishment. This idea took hold in the 19th century and became mainstream by the early 20th century. In the 1950s and 1960s, public concern grew because of a perceived lack of effectiveness and lack of rights. The Supreme Court made a series of rulings solidifying juvenile rights including the right to receive notice of charges, the right to have an attorney and the right to have charges proven beyond a reasonable doubt. In the 1980s, the public view was that the juvenile court system was too lenient and that juvenile crimes were on the rise. In the 1990s, many states passed punitive laws, including mandatory sentencing and blanket transfers to adult courts for certain crimes. As a result, the pendulum is now swinging back toward the middle from rehabilitation toward punishment.

Verma, Dev Kumar; Rathore, Gaurav

2015-01-01

Abstract Yellow pigmented, filamentous, Gram-negative bacteria belonging to genus Flavobacterium are commonly associated with infections in stressed fish. In this study, inter-species diversity of Flavobacterium was studied in apparently healthy freshwater farmed fishes. For this, ninety one yellow pigmented bacteria were isolated from skin and gill samples (n = 38) of three farmed fish species i.e. Labeo rohita, Catla catla and Cyprinus carpio. Among them, only twelve bacterial isolates (13.18%) were identified as Flavobacterium spp. on the basis of morphological, biochemical tests, partial 16S rDNA gene sequencing and phylogenetic analysis. On the basis of 16S rDNA gene sequencing, all the 12 isolates were 97.6-100% similar to six different formally described species of genus Flavobacterium. The 16S rDNA based phylogenetic analysis grouped these strains into six different clades. Of the 12 isolates, six strains (Fl9S1-6) grouped with F. suncheonense, two strains (Fl6I2, Fl6I3) with F. indicum and the rest four strains (Fl1A1, Fl2G1, Fl3H1 and Fl10T1) clustered with F. aquaticum, F. granuli, F. hercynium and F. terrae, respectively. None of these species except, F. hercynium were previously reported from fish. All the isolated Flavobacterium species possessed the ability of adhesion and biofilm formation to colonize the external surface of healthy fish. The present study is the first record of tropical freshwater farmed fishes as hosts to five environmentally associated species of the Flavobacterium. PMID:26691454

Th2-biased immune response and agglutinating antibodies generation by a chimeric protein comprising OmpC epitope (323-336) of Aeromonas hydrophila and LTB.

Aeromonas hydrophila is responsible for causing fatal infections in freshwater fishes. Besides chemical/antibiotic treatment and whole-cell vaccine, no subunit vaccine is currently available for A. hydrophila. Outer membrane proteins of gram-negative bacteria have been reported as effective vaccine candidates. Peptide antigens elicit focused immune responses against immunodominant stretches of the antigen. We have attempted to characterize the immunogenicity of linear B-cell epitopes of outer membrane protein (OmpC) of A. hydrophila identified using in silico tools, in conjugation with heat-labile enterotoxin B (LTB) subunit of Escherichia coli as a carrier protein. Antisera against the fusion protein harboring 323-336 residues of the AhOmpC (raised in mice) showed maximum cross-reactivity with the parent protein OmpC and LTB. The fusion protein displayed efficient GM 1 ganglioside receptor binding, retaining the adjuvanicity of LTB. Antibody isotype profile and in vitro T-cell response analysis, cytokine ELISA, and array analysis collectively revealed a Th2-biased mixed T-helper cell response. Agglutination assay and flow cytometry analysis validated the ability of anti-fusion protein antisera to recognize the surface exposed epitopes on Aeromonas cells, demonstrating its neutralization potential. Oral immunization studies in Labeo rohita resulted in the generation of long-lasting humoral immune response, and the antisera could cross-react with the fusion protein as well as both the fusion partners. Considering significant similarity among OmpC of different enteric bacteria, the use of A. hydrophila OmpC epitope 323-336 in fusion with LTB could have a broader scope in vaccine design.

Juvenile polyps involving the stomach are uncommon. Massive gastric juvenile polyposis is even rarer. We describe the clinicopathologic features of nine cases of massive gastric juvenile polyposis. All patients had anemia; four had hypoalbuminemia. The polyps were composed predominantly of dilated crypts lined by columnar epithelium and abundant edematous stroma with mixed inflammatory infiltrates. One patient had a poorly differentiated adenocarcinoma, arising in juvenile polyp-associated intraepithelial neoplasia. A second patient had a well-differentiated intramucosal adenocarcinoma arising in a juvenile polyp with high-grade dysplasia. Three of our cases had polyposis restricted to the stomach. Six (66.6%) had loss of SMAD4 immunoreactivity, making them subject to severe bleeding and hypoproteinemia, as well as developing severe dysplasia or adenocarcinoma. SMAD4 immunohistochemstry is a helpful ancillary diagnostic test in cases of suspected juvenile polyposis syndrome involving the stomach. © American Society for Clinical Pathology, 2017.

Predictors of involvement in the juvenile justice system among psychiatric hospitalized adolescents.

Cropsey, Karen L; Weaver, Michael F; Dupre, Madeleine A

2008-07-01

Several risk factors for juvenile justice involvement have been identified in previous research among delinquents and include mental illness, substance use, trauma and abuse, family dysfunction, poor parenting, school problems, and aggressive behavior. However, most of these predictors resulted from studies among adolescents incarcerated in the juvenile justice system. We were interested in finding out the prevalence rates of juvenile justice involvement among psychiatric inpatient adolescents and determining predictors of juvenile justice involvement in this high-risk group. Six hundred and thirty-six medical records from adolescents ages 12-17 years who were consecutively admitted to one of two psychiatric inpatient units between July 1, 2003 and June 30, 2004 were examined. Almost half (43.6%) of hospitalized adolescents had a history of juvenile justice involvement. Logistic regression analysis was conducted to determine predictors of juvenile justice involvement. Significant predictors of juvenile justice involvement included being male, parental legal history, family substance abuse history, disruptive disorder, cocaine use, being sexually active, and having a history of aggressive behavior. Adolescents in mental health or substance abuse treatment settings should be screened for juvenile justice involvement and appropriate referrals made to prevent worsening problems for at-risk youth.

Effects of Prior Experience on Shelter-Seeking Behavior of Juvenile American Lobsters.

PubMed

Bayer, Skylar R; Bianchi, Katherine M; Atema, Jelle; Jacobs, Molly W

2017-04-01

Shelter-seeking behaviors are vital for survival for a range of juvenile benthic organisms. These behaviors may be innate or they may be affected by prior experience. After hatching, American lobsters Homarus americanus likely first come into contact with shelter during the late postlarval (decapodid) stage, known as stage IV. After the subsequent molt to the first juvenile stage (stage V), they are entirely benthic and are thought to be highly cryptic. We hypothesized that postlarval (stage IV) experience with shelter would carry over into the first juvenile stage (stage V) and reduce the time needed for juveniles to locate and enter shelters (sheltering). We found some evidence of a carryover effect, but not the one we predicted: stage V juveniles with postlarval shelter experience took significantly longer to initiate sheltering. We also hypothesized that stage V juveniles would demonstrate learning by relocating shelters more quickly with immediate prior experience. Our findings were mixed. In a maze, juveniles with immediate prior experience were faster to regain visual contact with shelter, suggesting that they had learned the location of the shelter. In contrast, there was no significant effect of immediate prior experience on time to initiate sheltering in an open arena, or in the maze after juveniles had regained visual contact. We conclude that very young (stage V) juvenile lobsters modify their shelter-seeking behavior based on prior experiences across several timescales. Ecologically relevant variation in habitat exposure among postlarval and early juvenile lobsters may influence successful recruitment in this culturally and commercially important fishery species.

Setting a minimum age for juvenile justice jurisdiction in California.

S Barnert, Elizabeth; S Abrams, Laura; Maxson, Cheryl; Gase, Lauren; Soung, Patricia; Carroll, Paul; Bath, Eraka

2017-03-13

Purpose Despite the existence of minimum age laws for juvenile justice jurisdiction in 18 US states, California has no explicit law that protects children (i.e. youth less than 12 years old) from being processed in the juvenile justice system. In the absence of a minimum age law, California lags behind other states and international practice and standards. The paper aims to discuss these issues. Design/methodology/approach In this policy brief, academics across the University of California campuses examine current evidence, theory, and policy related to the minimum age of juvenile justice jurisdiction. Findings Existing evidence suggests that children lack the cognitive maturity to comprehend or benefit from formal juvenile justice processing, and diverting children from the system altogether is likely to be more beneficial for the child and for public safety. Research limitations/implications Based on current evidence and theory, the authors argue that minimum age legislation that protects children from contact with the juvenile justice system and treats them as children in need of services and support, rather than as delinquents or criminals, is an important policy goal for California and for other national and international jurisdictions lacking a minimum age law. Originality/value California has no law specifying a minimum age for juvenile justice jurisdiction, meaning that young children of any age can be processed in the juvenile justice system. This policy brief provides a rationale for a minimum age law in California and other states and jurisdictions without one.

2006-12-01

Self-healing juvenile cutaneous mucinosis is a rare disease affecting young people characterized by transient cutaneous lesions and sometimes mild inflammatory symptoms. The deep dermal and subcutaneous features of this disorder have not yet been well described. The purpose of our study was to present 3 cases of self-healing juvenile cutaneous mucinosis in which the histopathologic features caused diagnostic confusion between this disorder and proliferative fasciitis. The study includes clinical and histologic findings of 3 patients, complemented by a literature review. The histologic descriptions of nodular lesions in self-healing juvenile cutaneous mucinosis reveal features of proliferative fasciitis, including a myxoid stroma and gangliocyte-like giant cells. Self-healing juvenile cutaneous mucinosis is a rare condition and has not been frequently reported in medical literature. Our findings are based on the pathologic features of 3 patients. Our findings further elucidate the histologic features of self-healing juvenile cutaneous mucinosis and expand the differential diagnosis for entities in which gangliocyte-like giant cells are noted.

Reassessing the Anatomic Origin of the Juvenile Nasopharyngeal Angiofibroma.

McKnight, Colin D; Parmar, Hemant A; Watcharotone, Kuanwong; Mukherji, Suresh K

A modern imaging review is necessary to further define the anatomic origin of the juvenile nasopharyngeal angiofibroma. After institutional review board approval, a search from January 1998 to January 2013 yielded 33 male patients (aged 10-23 years) with pathologically proven juvenile nasopharyngeal angiofibroma lesions, as well as pretreatment computed tomography/magnetic resonance imaging. Juvenile nasopharyngeal angiofibroma involvement was assessed in the following regions: sphenopalatine foramen, pterygopalatine fossa, vidian canal, nasopharynx, nasal cavity, sphenoid sinus, choana, pterygomaxillary fissure/masticator space, orbit, and sphenoid bone. The choana and nasopharynx were involved in all 33 patients. In contrast, only 22 lesions involved the pterygopalatine fossa, 24 lesions involved the sphenopalatine foramen, and 28 lesions involved the vidian canal. Our results suggest that the juvenile nasopharyngeal angiofibroma origin is in the region of the choana and nasopharynx rather than the sphenopalatine foramen or pterygopalatine fossa.

Crocodylus acutus (American Crocodile). Long distance juvenile movement

Crespo, Rafael; Beauchamp, Jeffrey S.; Mazzotti, Frank; Cherkiss, Michael S.

2015-01-01

Crocodylus acutus (American Crocodile) is the most widely distributed New World crocodilian species with its range extending from Peru in the south to the southern tip of peninsular Florida in the north. Crocodylus acutus occupies primarily coastal brackish water habitat, however it also occurs in freshwater to hypersaline habitats (Thorbjarnarson 2010. In Crocodiles. Status Survey and Conservation Action Plan. [Third Edition], American Crocodile Crocodylus acutus, pp. 46–53 S.C. Manolis and C. Stevenson. Crocodile Specialist Group, Darwin). There is limited literature on long distance movements of juvenile crocodilians worldwide and no literature on juvenile crocodiles in Florida. However, adult C. acutus in Florida have been documented to make seasonal movements of 5–15 km from preferred foraging habitat to nesting beaches (Mazzotti 1983. The Ecology of Crocodylus acutus in Florida. PhD Dissertation. The Pennsylvania State University, University Park, Pennsylvania. 161pp), and one adult was documented making a 35 km trip from her nest site to preferred foraging habitat (Cherkiss et. al. 2006. Herpetol. Rev. 38:72–73). Rodda (1984. Herpetologica 40:444–451) reported on juvenile C. acutus movement in Gatun Lake, Panama, and found that juveniles stayed within 1 km of their nest site for the first month. Movements of juvenile Crocodylus porosus (Saltwater Crocodile) in a river system in Northern Australia showed a maximum movement of 38.9 km from a known nest site, with the majority of the crocodiles staying within 15.6 km downstream to 6.8 km upstream (Webb and Messel 1978. Aust. Wildlife Res. 5:263–283). Juvenile movement of Crocodylus niloticus (Nile Crocodile) in Lake Ngezi, Zimbabwe showed crocodiles restricted their movements from 1.0 km up to 4.5 km through the wet and dry seasons (Hutton 1989. Am. Zool. 29:1033–1049). Long distance movements of alligators were recorded for sizes ranging from 28 cm to 361 cm in a coastal refuge in Louisiana, where

Musculoskeletal MRI findings of juvenile localized scleroderma.

Eutsler, Eric P; Horton, Daniel B; Epelman, Monica; Finkel, Terri; Averill, Lauren W

2017-04-01

Juvenile localized scleroderma comprises a group of autoimmune conditions often characterized clinically by an area of skin hardening. In addition to superficial changes in the skin and subcutaneous tissues, juvenile localized scleroderma may involve the deep soft tissues, bones and joints, possibly resulting in functional impairment and pain in addition to cosmetic changes. There is literature documenting the spectrum of findings for deep involvement of localized scleroderma (fascia, muscles, tendons, bones and joints) in adults, but there is limited literature for the condition in children. We aimed to document the spectrum of musculoskeletal magnetic resonance imaging (MRI) findings of both superficial and deep juvenile localized scleroderma involvement in children and to evaluate the utility of various MRI sequences for detecting those findings. Two radiologists retrospectively evaluated 20 MRI studies of the extremities in 14 children with juvenile localized scleroderma. Each imaging sequence was also given a subjective score of 0 (not useful), 1 (somewhat useful) or 2 (most useful for detecting the findings). Deep tissue involvement was detected in 65% of the imaged extremities. Fascial thickening and enhancement were seen in 50% of imaged extremities. Axial T1, axial T1 fat-suppressed (FS) contrast-enhanced and axial fluid-sensitive sequences were rated most useful. Fascial thickening and enhancement were the most commonly encountered deep tissue findings in extremity MRIs of children with juvenile localized scleroderma. Because abnormalities of the skin, subcutaneous tissues and fascia tend to run longitudinally in an affected limb, axial T1, axial fluid-sensitive and axial T1-FS contrast-enhanced sequences should be included in the imaging protocol.

Juvenile Crime and Criminal Justice: Resolving Border Disputes

2016-01-01

Being an obligate parasite, juvenile common cuckoos Cuculus canorus are thought to reach their African wintering grounds from Palearctic breeding grounds without guidance from experienced conspecifics but this has not been documented. We used satellite tracking to study naïve migrating common cuckoos. Juvenile cuckoos left breeding sites in Finland moving slowly and less consistently directed than adult cuckoos. Migration of the juveniles (N = 5) was initiated later than adults (N = 20), was directed toward the southwest–significantly different from the initial southeast direction of adults–and included strikingly long Baltic Sea crossings (N = 3). After initial migration of juvenile cuckoos toward Poland, the migration direction changed and proceeded due south, directly toward the winter grounds, as revealed by a single tag transmitting until arrival in Northwest Angola where northern adult cuckoos regularly winter. Compared to adults, the juvenile travelled straighter and faster, potentially correcting for wind drift along the route. That both migration route and timing differed from adults indicates that juvenile cuckoos are able to reach proper wintering grounds independently, guided only by their innate migration programme.

Effect of TBT on Ruditapes decussatus juveniles.

PubMed

Coelho, M R; Langston, W J; Bebianno, M J

2006-06-01

The effects of sublethal concentrations of tributyltin (TBT) on growth of juvenile clams Ruditapes decussatus were determined during exposure to TBT concentrations of 50, 100 and 250 ng l(-1) (as Sn) for a period up to two years. Length and weight of clams increased continuously in all treatments throughout the experimental period, and, overall, rates were not significantly influenced by TBT exposure, although final length and weight were inversely related to increasing TBT concentration. Juvenile R. decussatus therefore appear to be less sensitive to TBT than larval stages. Some juveniles exposed to TBT developed abnormal shell growth, laterally, changing the typical flattened shape of clams into a more "rounded" form. This characteristic was more visible in the anterior margins of valves than posteriorly, and mainly observed in clams exposed to TBT at 50 ng l(-1) (as Sn).

Setting a minimum age for juvenile justice jurisdiction in California

PubMed Central

Barnert, Elizabeth S.; Abrams, Laura S.; Maxson, Cheryl; Gase, Lauren; Soung, Patricia; Carroll, Paul; Bath, Eraka

2018-01-01

Purpose Despite the existence of minimum age laws for juvenile justice jurisdiction in 18 US states, California has no explicit law that protects children (i.e. youth less than 12 years old) from being processed in the juvenile justice system. In the absence of a minimum age law, California lags behind other states and international practice and standards. The paper aims to discuss these issues. Design/methodology/approach In this policy brief, academics across the University of California campuses examine current evidence, theory, and policy related to the minimum age of juvenile justice jurisdiction. Findings Existing evidence suggests that children lack the cognitive maturity to comprehend or benefit from formal juvenile justice processing, and diverting children from the system altogether is likely to be more beneficial for the child and for public safety. Research limitations/implications Based on current evidence and theory, the authors argue that minimum age legislation that protects children from contact with the juvenile justice system and treats them as children in need of services and support, rather than as delinquents or criminals, is an important policy goal for California and for other national and international jurisdictions lacking a minimum age law. Originality/value California has no law specifying a minimum age for juvenile justice jurisdiction, meaning that young children of any age can be processed in the juvenile justice system. This policy brief provides a rationale for a minimum age law in California and other states and jurisdictions without one. Paper type Conceptual paper PMID:28299968

Long-wavelength (red) light produces hyperopia in juvenile and adolescent tree shrews.

PubMed

Gawne, Timothy J; Ward, Alexander H; Norton, Thomas T

2017-11-01

In infant tree shrews, exposure to narrow-band long-wavelength (red) light, that stimulates long-wavelength sensitive cones almost exclusively, slows axial elongation and produces hyperopia. We asked if red light produces hyperopia in juvenile and adolescent animals, ages when plus lenses are ineffective. Animals were raised in fluorescent colony lighting (100-300 lux) until they began 13days of red-light treatment at 11 (n=5, "infant"), 35 (n=5, "juvenile") or 95 (n=5, "adolescent") days of visual experience (DVE). LEDs provided 527-749 lux on the cage floor. To control for the higher red illuminance, a fluorescent control group (n=5) of juvenile (35 DVE) animals was exposed to ∼975 lux. Refractions were measured daily; ocular component dimensions at the start and end of treatment and end of recovery in colony lighting. These groups were compared with normals (n=7). In red light, the refractive state of both juvenile and adolescent animals became significantly (P<0.05) hyperopic: juvenile 3.9±1.0 diopters (D, mean±SEM) vs. normal 0.8±0.1D; adolescent 1.6±0.2D vs. normal 0.4±0.1D. The fluorescent control group refractions (0.6±0.3D) were normal. In red-treated juveniles the vitreous chamber was significantly smaller than normal (P<0.05): juvenile 2.67±0.03mmvs. normal 2.75±0.02mm. The choroid was also significantly thicker: juvenile 77±4μmvs. normal 57±3μm (P<0.05). Although plus lenses do not restrain eye growth in juvenile tree shrews, the red light-induced slowed growth and hyperopia in juvenile and adolescent tree shrews demonstrates that the emmetropization mechanism is still capable of restraining eye growth at these ages.

Cutaneous xanthogranulomas, hepatosplenomegaly, anemia, and thrombocytopenia as presenting signs of juvenile myelomonocytic leukemia.

PubMed

Cham, Elaine; Siegel, Dawn; Ruben, Beth S

2010-01-01

The development of xanthogranulomas has been linked to hematologic malignancies in children and adults, based on a number of reports in the literature. In children, a specific association between juvenile xanthogranuloma, neurofibromatosis 1, and juvenile myelomonocytic leukemia has been described. We report a case of a 9-month-old child, without a known diagnosis of neurofibromatosis 1, who presented with hepatosplenomegaly, anemia, thrombocytopenia, and multiple cutaneous nodules, which were confirmed to be juvenile xanthogranulomas upon biopsy. A concurrent work-up showed that the child had juvenile myelomonocytic leukemia. Although cutaneous juvenile xanthogranulomas are benign lesions, in several reported cases they have been shown to herald leukemia. This association between xanthogranulomas and hematologic malignancy is poorly understood. Juvenile xanthogranulomas have a number of morphologic variants and clinical presentations that can be confused with the cutaneous lesions of Langerhans cell histiocytosis and dermatofibroma. Recognition of the broad clinicopathologic spectrum of juvenile xanthogranulomas is critical for proper diagnosis.

Tracking from the tropics reveals behaviour of juvenile songbirds on their first spring migration.

2014-01-01

Juvenile songbirds on spring migration travel from tropical wintering sites to temperate breeding destinations thousands of kilometres away with no prior experience to guide them. We provide a first glimpse at the migration timing, routes, and stopover behaviour of juvenile wood thrushes (Hylocichla mustelina) on their inaugural spring migration by using miniaturized archival geolocators to track them from Central America to the U.S. and Canada. We found significant differences between the timing of juvenile migration and that of more experienced adults: juveniles not only departed later from tropical wintering sites relative to adults, they also became progressively later as they moved northward. The increasing delay was driven by more frequent short stops by juveniles along their migration route, particularly in the U.S. as they got closer to breeding sites. Surprisingly, juveniles were just as likely as adults to cross the Gulf of Mexico, an open-water crossing of 800-1000 km, and migration route at the Gulf was not significantly different for juveniles relative to adults. To determine if the later departure of juveniles was related to poor body condition in winter relative to adults, we examined percent lean body mass, fat scores, and pectoral muscle scores of juvenile versus adult birds at a wintering site in Belize. We found no age-related differences in body condition. Later migration timing of juveniles relative to adults could be an adaptive strategy (as opposed to condition-dependent) to avoid the high costs of fast migration and competition for breeding territories with experienced and larger adults. We did find significant differences in wing size between adults and juveniles, which could contribute to lower flight efficiency of juveniles and thus slower overall migration speed. We provide the first step toward understanding the "black box" of juvenile songbird migration by documenting their migration timing and en route performance.

Treatment and postrelease rehabilitative programs for juvenile offenders.

PubMed

Underwood, Lee A; Knight, Pamela

2006-04-01

The juvenile justice system has become notably aware of the increasing use of postrelease rehabilitative treatment interventions for offenders. In many instances, juvenile justice systems are required to ensure that core treatment needs of youth are met. As a result of the heightened awareness of the need for postrelease rehabilitation treatment programs, many researchers and providers are calling for more systematic approaches to offender treatment. This article summarizes a body of literature on juvenile offenders who have specialized postrelease rehabilitative treatment needs. It reviews cognitive-behavioral theoretical models and core postrelease treatment strategies. It presents a review of youth who have specialized needs in light of postrelease practices, describes several model postrelease rehabilitation programs, and reviews outcomes of these programs.

Movies and juvenile delinquency: an overview.

PubMed

Snyder, S

1991-01-01

Film viewing may affect the juvenile delinquent through the processes known as social learning and instigation. Identification with the movie and its characters by the delinquent viewer is common, and studies have consistently demonstrated that films can affect delinquents, although in some cases the effects are small. Numerous examples of how films may serve as either the initiator or the final common pathway of delinquent acts are presented. However, prosocial aspects of films dealing with delinquency may exert a positive influence on the juvenile delinquent. Treatment implications of these observations are discussed from social learning and other perspectives.

2011-09-01

Juvenile nasopharyngeal angiofibroma may be successfully resected using endoscopic techniques. However, the use of coblation technology for such resection has not been described. This study aimed to document cases of Fisch class I juvenile nasopharyngeal angiofibroma with limited nasopharyngeal and nasal cavity extension, which were completely resected using an endoscopic coblation technique. We retrospectively studied 23 patients with juvenile nasopharyngeal angiofibroma who underwent resection with either traditional endoscopic instruments (n = 12) or coblation (n = 11). Intra-operative blood loss and overall operative time were recorded. The mean tumour resection time for coblation and traditional endoscopic instruments was 87 and 136 minutes, respectively (t = 9.962, p < 0.001). Mean intra-operative blood loss was 121 and 420 ml, respectively (t = 28.944, p < 0.001), a significant difference. Both techniques achieved complete tumour resection with minimal damage to adjacent tissues, and no recurrence in any patient. Coblation successfully achieves transnasal endoscopic resection of juvenile nasopharyngeal angiofibroma (Fisch class I), with good surgical margins and minimal blood loss.

2017-09-01

A myxozoan parasite belonging to the genus Thelohanellus Kudo, 1933 (Myxosporea, Bivalvulida) was isolated from the gill lamellae of Labeo bata (Hamilton, 1822) inhabiting Ranjit Sagar Wetland in Northern parts of Punjab, India. Histopathology of the infected gills indicated lamellar distortion due to the presence of plasmodia. The intensity of infection was recorded to be moderate as indicated by gill plasmodial index (GPI = 2). The plasmodia were microscopic, ovoid, creamish white, 2.0-4.0 mm in diameter containing 300-400 number of myxospores. The myxospores were broadly pyriform in shape, measuring 8.27 × 4.41 µm, having a prominent pore at the anterior end. The polar capsule was pyriform in shape, measuring 4.15 × 4.10 µm, containing a polar filament coiled perpendicular to the longitudinal axis of myxospore body making 6-7 turns. At molecular level, the analysis of 18S rDNA sequence of T. theinensis n. sp. demonstrated maximum homogeneity of 99 % with T. filli (KR340464) as only 2 gaps were found due to the difference of the last 20 base pairs at the 3' end of T. theinensis n. sp. The current study emphasizes the need for caution when dealing with members of species complex.

The developing juvenile ischium: macro-radiographic insights.

Maclean, Stephen J; Black, Sue M; Cunningham, Craig A

2014-09-01

Despite the importance of the human pelvis as a weight-bearing structure, there is a paucity of literature that discusses the development of the juvenile innominate from a biomechanical perspective. This study aims to add to the limited body of literature pertaining to this topic through the qualitative analysis of the gross architecture of the human ischium during the juvenile period. Macro-radiographs of 55 human ischia ranging from 28 intra-uterine weeks to 14 years of age were examined using intensity-gradient color mapping to highlight changes in gross structural morphology with increasing age. A clear pattern of maturation was observed in the juvenile ischium with increasing age. The acetabular component and ramus of the ischium consistently displayed low bone intensity in the postnatal skeletal material. Conversely the posterior body of the ischium, and in particular the ischial spine and lesser sciatic notch, exhibited increasing bone intensity which first arose at 1-2 years of age and became more expansive in older cohorts. The intensity patterns observed within the developing juvenile ischium are indicative of the potential factors influencing the maturation of this skeletal element. While the low intensity acetabular fossa indicates a lack of significant biomechanical interactions, the posterior increase in bone intensity may be related to the load-bearing nature of the posterior ischium. © 2014 Wiley Periodicals, Inc.

Previous studies showed that moderate exercise in adult rats enhances neutrophil function, although no studies were performed in juvenile rats. We evaluated the effects of moderate exercise on the neutrophil function in juvenile rats. Viability and neutrophils function were evaluated. Moderate exercise did not impair the viability and mitochondrial transmembrane potential of neutrophils, whereas there was greater reactive oxygen species production (164%; p < 0.001) and phagocytic capacity (29%; p < 0.05). Our results suggest that moderate exercise in juvenile rats improves neutrophil function, similar to adults.

Drought tolerance in eggs and juveniles of the Iberian slug, Arion lusitanicus.

Slotsbo, Stine; Fisker, Karina Vincents; Hansen, Lars Monrad; Holmstrup, Martin

2011-12-01

The spread of invasive species is an increasing problem world wide. The invasive slug Arion lusitanicus has spread to most parts of Europe, where it often is considered as a serious pest. There is a need for better knowledge of its ecophysiology to be able to predict the effect of climatic factors, such as temperature and humidity on the population dynamics and abundance. The aim of the present study was to assemble data on the water balance and drought tolerance of eggs and juveniles of A. lusitanicus. Both eggs and juveniles had little capacity to prevent evaporative water loss and lost water when the ambient humidity fell below 99.8 and 99.5%, respectively. The water conductance of the cuticle of juveniles was 242 μg cm(-2) h(-1) mmHg(-1) and resembles that of other slug species. Both eggs and juveniles of A. lusitanicus tolerate a substantial water loss. There was no difference in water loss resistance between eggs and juveniles, but the eggs were slightly more tolerant to water loss than the juveniles. The percent water loss causing 50% mortality was 72% for the juveniles and 81% for the eggs. Despite A. lusitanicus' tolerance of substantial water loss, its survival depends on humid habitats.

Juvenile Fibromyalgia: A Multidisciplinary Approach to Treatment.

Tesher, Melissa S

2015-06-01

A 14-year-old boy presented with months of severe widespread musculoskeletal pain. He was profoundly fatigued and unable to attend school. Laboratory evaluation, including complete blood count, comprehensive metabolic panel, inflammatory markers, and thyroid function, was unrevealing. Physical examination was also normal except for multiple tender points. The patient was diagnosed with juvenile primary fibromyalgia syndrome and referred for multidisciplinary treatment including physical therapy, exercise, and counseling, and his daily functioning gradually improves. Juvenile fibromyalgia is a complex syndrome that often severely limits patients' activities and can impede normal adolescent development. Effective treatment requires an understanding of the biologic, psychologic, and social factors contributing to the perpetuation of chronic pain. The author reviews the diagnostic criteria, pathophysiology, and treatment of juvenile fibromyalgia. Medications, particularly antidepressants and anticonvulsants, can be useful adjuncts to therapy. However, multimodal pain management including intensive physical therapy, exercise, counseling, and sleep hygiene is most effective in treating fibromyalgia. Copyright 2015, SLACK Incorporated.

[No X-chromosome linked juvenile foveal retinoschisis].

Pérez Alvarez, M J; Clement Fernández, F

2002-08-01

To describe the clinical characteristics of two cases of juvenile foveal retinoschisis in women with an atypical hereditary pattern, no X-chromosome linked. An autosomal recessive inheritance is proposed. Two generations of a family (5 members) in which only two sisters were evaluated. The complete examination of these two cases includes retinography, fluorescein angiography, automated perimetry, color vision testing, electroretinogram, electrooculogram and visually evoked potentials. Comparing our cases with the classic form of X-linked juvenile retinoschisis, they are less severely affected. The best visual acuity and the less disturbed or even normal electroretinogram confirm this fact. We emphasise the existence of isolated plaques of retinal pigment epithelium atrophy with perivascular pigment clumps without foveal schisis in one patient, which could represent an evolved form of this entity. The hereditary foveal juvenile retinoschisis in women suggests an autosomal inheritance (autosomal recessive in our cases) and presents less severe involvement (Arch Soc Esp Oftalmol 2002; 77: 443-448).

Risk assessment for juvenile justice: a meta-analysis.

Schwalbe, Craig S

2007-10-01

Risk assessment instruments are increasingly employed by juvenile justice settings to estimate the likelihood of recidivism among delinquent juveniles. In concert with their increased use, validation studies documenting their predictive validity have increased in number. The purpose of this study was to assess the average predictive validity of juvenile justice risk assessment instruments and to identify risk assessment characteristics that are associated with higher predictive validity. A search of the published and grey literature yielded 28 studies that estimated the predictive validity of 28 risk assessment instruments. Findings of the meta-analysis were consistent with effect sizes obtained in larger meta-analyses of criminal justice risk assessment instruments and showed that brief risk assessment instruments had smaller effect sizes than other types of instruments. However, this finding is tentative owing to limitations of the literature.

Arc restores juvenile plasticity in adult mouse visual cortex

Jenks, Kyle R.; Kim, Taekeun; Pastuzyn, Elissa D.; Okuno, Hiroyuki; Taibi, Andrew V.; Bear, Mark F.

2017-01-01

The molecular basis for the decline in experience-dependent neural plasticity over age remains poorly understood. In visual cortex, the robust plasticity induced in juvenile mice by brief monocular deprivation during the critical period is abrogated by genetic deletion of Arc, an activity-dependent regulator of excitatory synaptic modification. Here, we report that augmenting Arc expression in adult mice prolongs juvenile-like plasticity in visual cortex, as assessed by recordings of ocular dominance (OD) plasticity in vivo. A distinguishing characteristic of juvenile OD plasticity is the weakening of deprived-eye responses, believed to be accounted for by the mechanisms of homosynaptic long-term depression (LTD). Accordingly, we also found increased LTD in visual cortex of adult mice with augmented Arc expression and impaired LTD in visual cortex of juvenile mice that lack Arc or have been treated in vivo with a protein synthesis inhibitor. Further, we found that although activity-dependent expression of Arc mRNA does not change with age, expression of Arc protein is maximal during the critical period and declines in adulthood. Finally, we show that acute augmentation of Arc expression in wild-type adult mouse visual cortex is sufficient to restore juvenile-like plasticity. Together, our findings suggest a unifying molecular explanation for the age- and activity-dependent modulation of synaptic sensitivity to deprivation. PMID:28790183

The shallow coastal zone is an essential nursery habitat for juvenile flatfish species such as sole (Solea solea L.). The increased frequency of shoreface nourishments along the coast is likely to affect this nursery function by altering important habitat conditions, including sediment grain size. Sediment preference of juvenile sole (41-91 mm) was studied in a circular preference chamber in order to understand the relationship between grain size and sole distribution. The preference tests were carried out at 11 °C and 20 °C to reflect seasonal influences. The juveniles showed a significant preference for finer sediments. This preference was not length dependent (within the length range tested) nor affected by either temperatures. Juvenile sole have a small home range and are not expected to move in response to unfavourable conditions. As a result, habitat alterations may have consequences for juvenile survival and subsequently for recruitment to adult populations. It is therefore important to carefully consider nourishment grain size characteristics to safeguard suitable nursery habitats for juvenile sole.

We report a case of juvenile dermatomyositis that presented with periorbital edema. Dermatomyositis is an autoimmune disorder with cutaneous manifestations including heliotrope patches, Gottron's papules, periungual telangiectasisas, and subcutaneous calcifications. Periorbital edema may accompany the classic heliotrope rash and, as in this case, may be the only presenting sign of juvenile dermatomyositis.

Youth involved in the juvenile justice system represent a medically underserved population. Recidivist youth have poorer health outcomes compared to youth detained for the first time. This study determined differences in immunization history, substance use, mental health symptoms, and sexual behavior between recidivist youth and first-time detainees following improvements in intake screenings at a large, urban juvenile detention center in the Southeastern United States. Multivariable logistic regression analysis found that recidivist youth had significantly higher acellular pertussis immunization rates compared with first-time detainees (odds ratio [ OR] = 3.3; p = .02), and recidivist males were less likely to test positive for chlamydia ( OR = 0.6; p = .03) after controlling for age and Black race. There was no significant difference for most other outcomes between recidivist youth and first-time detainees after controlling for age.

Substance use and criminality among juveniles-under-enquiry in New Delhi

PubMed Central

Sharma, Shridhar; Sharma, Gautam; Barkataki, Bristi

2016-01-01

Background: There is an intimate relationship between drugs and criminal behavior. The drug–violence relationship is further complicated by intoxicating doses and/or withdrawal effects of specific drugs. Understanding this relationship is important for both healthcare workers and policy makers. Materials and Methods: The study was conducted in Prayas observation home for boys, a short stay home for juveniles-under-enquiry in New Delhi. The present study aims to correlate substance use and criminal behavior by investigating the sociodemographic characteristics and the current trend of substance use among juveniles in New Delhi. In this study, 487 detained juveniles aged between 8 and 18 years were included. The information was obtained by face-to-face semi-structured interviews and juvenile case records maintained by the juvenile home. Results: Out of 487 juveniles-under-enquiry booked under different crimes, 86.44% of the sample had a history of substance use. Consumption of tobacco and cannabis were higher when compared to other drugs. Consumption of psychotropic drugs though relatively lesser was related with more serious crimes. There is an increasing trend in serious crimes such as rape, murder/attempt to murder, and burglary committed by juveniles. Drug-crime correlation has been noted among consumption of cannabis with murder, inhalants with rape and opioids with snatching-related crimes. Conclusion: Substance use and criminal behavior are clearly interrelated. Greater the involvement in substance abuse, more severe is the violence and criminality. This paper highlights this complex relationship and suggests possible scope of interventions. PMID:27385851

2012-01-01

Juvenile firesetting activity accounts for a significant number of annual injuries and property damage, yet there is sparse information on intervention in the burn literature. To quantify juvenile firesetting intervention (JFSI) in burn centers, a 23-question survey was sent to all directors listed in the American Burn Association Burn Care Facilities Directory.Sixty-four out of 112 (57%) surveys were returned. This represents responses from 79% of currently verified burn centers. When queried on interventions provided to a juvenile firesetter admitted to their unit, 38% report having their own JFSI program and 38% refer the child to fire services. Two thirds of units without a JFSI program treat pediatric patients. Units that previously had a JFSI program report lack of staffing and funding as most common reasons for program discontinuation. Almost all (95%) stated that a visual tool demonstrating legal, financial, social, future, and career ramifications associated with juvenile firesetting would be beneficial to their unit. Many burn units that treat pediatric patients do not have JFSI and rely on external programs operated by fire services. Existing JFSI programs vary greatly in structure and method of delivery. Burn centers should be involved in JFSI, and most units would benefit from a new video toolkit to assist in providing appropriate JFSI. Study results highlight a need for burn centers to collaborate on evaluating effectiveness of JFSI programs and providing consistent intervention materials based on outcomes research.

Two alternative juvenile life history types for fall Chinook salmon in the Snake River basin

2005-01-01

Fall Chinook salmon Oncorhynchus tshawytscha in the Snake River basin were listed under the Endangered Species Act in 1992. At the time of listing, it was assumed that fall Chinook salmon juveniles in the Snake River basin adhered strictly to an ocean-type life history characterized by saltwater entry at age 0 and first-year wintering in the ocean. Research showed, however, that some fall Chinook salmon juveniles in the Snake River basin spent their first winter in a reservoir and resumed seaward movement the following spring at age 1 (hereafter, reservoir-type juveniles). We collected wild and hatchery ocean-type fall Chinook salmon juveniles in 1997 and wild and hatchery reservoir-type juveniles in 1998 to assess the condition of the reservoir-type juveniles at the onset of seaward movement. The ocean-type juveniles averaged 112-139 mm fork length, and the reservoir-type juveniles averaged 222-224 mm fork length. The large size of the reservoir-type juveniles suggested a high potential for survival to salt water and subsequent return to freshwater. Scale pattern analyses of the fall Chinook salmon spawners we collected during 1998-2003 supported this point. Of the spawners sampled, an overall average of 41% of the wild fish and 51% of the hatchery fish had been reservoir-type juveniles. Males that had been reservoir-type juveniles often returned as small "minijacks" (wild, 16% of total; hatchery, 40% of total), but 84% of the wild males, 60% of the hatchery males, and 100% of the wild and hatchery females that had been reservoir-type juveniles returned at ages and fork lengths commonly observed in populations of Chinook salmon. We conclude that fall Chinook salmon in the Snake River basin exhibit two alternative juvenile life histories, namely ocean-type and reservoir-type. ??

Recruitment in a sea anemone population: juvenile substrate becomes adult prey.

PubMed

Sebens, K P

1981-08-14

Populations of the sea anemone Anthopleura xanthogrammica (Brandt) occur in tide pools and surge channels below intertidal mussel beds where they capture mussels dislodged by wave action and by sea star foraging. Dense concentrations of small juvenile anemones occur only within mussel beds and are probably the result of larval settlement or differential survival in that habitat. Areas experimentally cleared of anemones showed that recruitment was primarily by migrating juveniles and that the rate of immigration over a 2-year period was much higher in experimental removal areas near mussel beds than in those further away. Mussel beds thus function as an important juvenile habitat (refuge and nursery); juveniles later migrate downward and are then in a position to capture dislodged mussels and grow to adult size.

Given the frequency and violent character of the traumas encountered by juvenile offenders, staff members who regularly interact with juveniles in custody are at risk of developing secondary traumatic stress. Juvenile justice teachers and staff (N = 118) were administered a cross-sectional survey, including the Secondary Traumatic Stress Scale. Respondents said the students were moderately traumatized (47%), severely traumatized (27%), and very severely traumatized (7%). Regarding STS, the most frequently reported symptom was intrusive thoughts related to work with the students, mentioned by 61% of respondents. Additionally, 81% met at least one, 55% met two, and 39% met all three core diagnostic criteria for posttraumatic stress disorder. Recommendations for juvenile justice staff members and for the organization are provided to address practice and policy implications.

Juvenile hormone is an essential regulator of major developmental and life history events in arthropods. Most of the insects use juvenile hormone III as the innate juvenile hormone ligand. By contrast, crustaceans use methyl farnesoate. Despite this difference that is tied to their deep evolutionary divergence, the process of this ligand transition is unknown. Here we show that a single amino-acid substitution in the receptor Methoprene-tolerant has an important role during evolution of the arthropod juvenile hormone pathway. Microcrustacea Daphnia pulex and D. magna share a juvenile hormone signal transduction pathway with insects, involving Methoprene-tolerant and steroid receptor coactivator proteins that form a heterodimer in response to various juvenoids. Juvenile hormone-binding pockets of the orthologous genes differ by only two amino acids, yet a single substitution within Daphnia Met enhances the receptor's responsiveness to juvenile hormone III. These results indicate that this mutation within an ancestral insect lineage contributed to the evolution of a juvenile hormone III receptor system.

Most studies assessing the burden of psychiatric disorders in juvenile correctional facilities have been based on small or male-only samples or have focused on a single disorder. Using electronic data routinely collected by the Texas juvenile correctional system and its contracted medical provider organization, we estimated the prevalence of selected psychiatric disorders among youths committed to Texas juvenile correctional facilities between January 1, 2004, and December 31, 2008 (N = 11,603). Ninety-eight percent were diagnosed with at least one of the disorders. Highest estimated prevalence was for conduct disorder (83.2%), followed by any substance use disorder (75.6%), any bipolar disorder (19.4%), attention-deficit/hyperactivity disorder (18.3%), and any depressive disorder (12.6%). The estimated prevalence of psychiatric disorders among these youths was exceptionally high and showed patterns by sex, race/ethnicity, and age that were both consistent and inconsistent with other juvenile justice samples.

Psychopathology and personality in juvenile sexual homicide offenders.

PubMed

Myers, W C; Blashfield, R

1997-01-01

This project describes the psychopathology and personality findings in 14 juveniles who committed sexual homicide. These incarcerated youth were assessed using a structured interview, a personality assessment instrument, correctional files review, and an author-designed clinical interview. Nearly all of these youth met DSM-III-R conduct disorder criteria at the time of the crime. The presence of personality disorders and moderately high psychopathy scores at follow-up were common. Two-thirds of these youth reported the presence of violent sexual fantasies before their crimes. Weapons, most often knives, were used by these juvenile sexual murderers to kill known victims in a majority of the cases. They usually acted alone and selected a low risk victim. These findings suggest that juvenile sexual murderers are an emotionally and behaviorally disturbed population with identifiable psychopathology, personality disturbances, and criminal patterns.

The monogenean ectoparasite, Dactylogyrus sp. is a major pathogen in freshwater aquaculture. The immune responses in parasitized fish were analyzed by quantitation of innate immune factors (natural agglutinin level, haemolysin titre, antiprotease, lysozyme and myeloperoxidase activities) in serum and immune-relevant gene expression in gill and anterior kidney. The antiprotease activity and natural agglutinin level were found to be significantly higher and lysozyme activity was significantly lower in parasitized fish. Most of the genes viz., beta2-microglobulin (beta2M), major histocompatibility complex I (MHCI), MHCII, tumor necrosis factor alpha (TNFalpha) and toll-like receptor 22 (TLR22) in gill samples were significantly down-regulated in the experimental group. In the anterior kidney, the expression of superoxide dismutase and interleukin 1beta (IL1beta) were significantly up-regulated whereas a significant down regulation of MHCII and TNFalpha was also observed. The down-regulation of most of the genes viz, MHCI, beta2M, MHCII, TLR22 and TNFalpha in infected gills indicated a well evolved mechanism in this parasite to escape the host immune response. The modulation of innate and adaptive immunity by this parasite can be further explored to understand host susceptibility.

Do benthic sediment characteristics explain the distribution of juveniles of the deposit-feeding sea cucumber Australostichopus mollis?

NASA Astrophysics Data System (ADS)

Slater, Matthew J.; Jeffs, Andrew G.

2010-10-01

Despite the economic importance of many deposit-feeding sea cucumbers, the ecology of their juveniles is poorly understood and factors influencing juvenile habitat selection remain largely unexplained. We investigated the importance of the characteristics of the available sediment in determining the highly localised distribution of juveniles of the deposit-feeding Australasian sea cucumber Australostichopus mollis. Wild-caught juveniles were displaced to non-juvenile habitats with surface sediments characterised by lower total organic content (TOM) and nitrogen content, higher chlorophyll- a content and coarser grain size profiles compared to juvenile sites. The growth of displaced individual animals was monitored over 9 months and compared to control animals caged in the juvenile habitats. Displaced juvenile sea cucumbers had high survival rates that did not differ significantly from juvenile habitats. Displaced juveniles exhibited significantly higher specific growth rate (SGR) than those at juvenile sites ( p < 0.001), although the growth of individuals was highly variable within individual cages and among sites. The lower TOM and nitrogen content, and coarser grain size profiles at non-juvenile sites did not result in reductions in juvenile survival or growth. Higher microphytobenthic activity may have resulted in the higher growth rates observed at shallow non-juvenile sites. The SGR of juveniles over the first 6 months of the experiment ranged between 0.45% d - 1 and 0.74% d - 1 for all sites. This was followed by marked growth limitation between 6 and 9 months either as a result of increasing juvenile biomass in cages or seasonal growth limitation. A subsequent reduction in juvenile density resulted in markedly increased growth over the following 3 month period. Juvenile A. mollis show an ability to exploit a variety of benthic sediment food sources, indicating that their highly localised distribution is not due to differences in the food quality of

Mental health care for Brazilian juvenile offenders.

PubMed

Costa, Nilson do Rosário; Silva, Paulo Roberto Fagundes da

2017-05-01

This paper analyzes the use of psychoactive drugs by juvenile offenders in Brazil in socio-educational facilities (USEs). It describes the guidelines of the national public policy and the quality of mental healthcare coordination by subnational public governments. This work draws on the hypothesis that USEs vertical governance is associated with the use of psychoactive medication. This is comparative study of two cases in Rio Grande do Sul and Minas Gerais. Data resulted from a sample of medical records and interviews with key informants. The paper shows that vertical governance observed in Rio Grande do Sul is directly associated with high prevalence of mental health disorder diagnosis, use of psychoactive medication and psychiatric medicalization by juvenile offenders deprived of liberty. These findings indicate that sanctions of imprisonment for illegal acts are producing a set of medicalization decisions that undermine juveniles' health rights. The national mental health policy guidelines encourage cautious decisions. Psychotherapies and rehabilitation actions are the advocated first-line interventions. The poor management of the psychopharmacological intervention favors multiple prescriptions.

Sonographic diagnosis of juvenile polyps in children.

2012-09-01

The aim of this study was to assess the diagnostic value of ultrasonography for juvenile polyps in children and their sonographic characteristics. A retrospective analysis was performed of the ultrasound findings in 27 children who were diagnosed preoperatively with juvenile polyp within the intestinal tract by ultrasonography and then confirmed by colonoscopy, laparotomy and histopathology. The ultrasonic finding common to all polyps was an isolated intraluminal nodular or massive protrusion, associated with multiple mesh-like fluid areas of different sizes. In 25 children, surrounding pedicle-like low echoes of varying lengths were seen connecting with the polyps to form "mushroom" sign. The color Doppler showed abundant blood flow signals within all polyps and pedicles in a shape of a branch or an umbrella. For seven children with an intussusception, the polyp shadow was detected in the cervical part or interior of the intussusception. Ultrasonography is, thus, considered to be a feasible method for diagnosing intestinal juvenile polyp. Copyright © 2012 World Federation for Ultrasound in Medicine & Biology.

ABSTRACT The ontogeny of migration routines used by wild birds remains unresolved. Here we investigated the migratory orientation of juvenile lesser spotted eagles (LSE; Clanga pomarina) based on translocation and satellite tracking. Between 2004 and 2016, 85 second-hatched juveniles (Abels) were reared in captivity for release into the declining German population, including 50 birds that were translocated 940 km from Latvia. In 2009, we tracked 12 translocated juveniles, as well as eight native juveniles and nine native adults, to determine how inexperienced birds come to use strategic migration routes. Native juveniles departed around the same time as the adults and six of eight used the eastern flyway around the Mediterranean, which was used by all adults. In contrast, translocated juveniles departed on average 6 days before native LSEs, and five travelled southward and died in the central Mediterranean region. Consequently, fewer translocated juveniles (4/12) than native juveniles (7/8) reached Africa. We conclude that juvenile LSEs have a much better chance of learning the strategic southeastern flyway if they leave at an appropriate time to connect with experienced elders upon departure. It is not clear why translocated juveniles departed so early. Regardless, by the end of the year, most juveniles had perished, whether they were translocated (10/12) or not (6/8). The small number of surviving translocated juveniles thus still represents a significant increase in the annual productivity of the German LSE population in 2009. PMID:28768749

The Society of Toxicologic Pathology (STP) Education Committee and the STP Reproductive Special Interest Group held a North Carolina regional meeting entitled, “Juvenile Toxicology: Relevance and Challenges for Toxicologists and Pathologists” on March 13, 2015, at the National Institute of Environmental Health Sciences/National Toxicology Program in Research Triangle Park, North Carolina. The purpose of this regional meeting was to familiarize attendees with the topic of juvenile toxicity testing and discuss its relevance to clinical pediatric medicine, regulatory perspectives, challenges of appropriate study design confronted by toxicologists, and challenges of histopathologic examination and interpretation of juvenile tissues faced by pathologists. The 1-day meeting was a success with over 60 attendees representing industry, government, research organizations, and academia. PMID:26220944

We found an epidemic of juvenile hypothyroidism among a population of self-defined "downwinders" living near the Hanford nuclear facility located in southeast Washington State. The episode followed massive releases of 131I. Self-reported data on 60 cases of juvenile hypothyroidism (<20 years of age) among a group of 801 Hanford downwinders are presented, as well as data concerning the thyroid status of approximately 160,000 children exposed to radioiodine before 10 years of age as a result of the 26 April 1986 Chernobyl explosion in the former Soviet Union. These children were residents of five regions near Chernobyl. They were examined by standardized screening protocols over a period of 5 years from 1991 to 1996. They are a well-defined group of 10 samples. Fifty-six cases of hypothyroidism were found among boys and 92 among girls. Body burdens of 137Cs have been correlated with hypothyroidism prevalence rates. On the other hand, the group of juvenile (<20 years of age) Hanford downwinders is not a representative sample. Most of the 77 cases of juvenile hypothyroidism in the Hanford group were diagnosed from 1945 to 1970. However, the ratio of reported cases to the county population under 20 years of age is roughly correlated with officially estimated mean levels of cumulative thyroid 131I uptake in these counties, providing evidence that juvenile hypothyroidism was associated with radioiodine exposures. Because even subtle hypothyroidism may be of clinical significance in childhood and can be treated, it may be useful to screen for the condition in populations exposed to radioiodine fallout. Although radiation exposure is associated with hypothyroidism, its excess among fallout-exposed children has not been previously quantified.

Objective: Although not originally enacted to deter the problem of underage drinking in the United States, one set of laws that may influence this behavior is juvenile curfew laws. This research asked the following: (a) What is the effect of enacting a juvenile curfew law on youth drinking, and (b) do demographic variables moderate the relation between juvenile curfew law enactment and drinking? This study examined the effect of juvenile curfew laws on underage drinking, using data from 46 U.S. cities from 1991 to 2005. Method: In 2014, we compiled a data set containing alcohol and curfew law data by zip code. It included 63,081 minors (ages 12–17 years) from 1,081 zip codes. We used difference-in-difference regressions to analyze the data. Results: The effect of the enactment of a curfew law on the likelihood of consuming alcohol in the past year or past 30 days or of heavy episodic drinking in the past 2 weeks was not significant when compared with cities without curfew laws during the same periods. Although the likelihood of consuming alcohol over the past year differed depending on an individual’s characteristics (e.g., race/ethnicity, age, and gender), none of the interaction terms between these characteristics and curfew laws were significant. Conclusions: Curfew laws appear to have a non-significant effect on youth drinking, but these results are unclear without more knowledge as to where and when youth are drinking both before and after the enactment of curfew laws and how these laws are being enforced.

2006-04-01

To analyze the clinical profile of juvenile hyperthyroidism at presentation, their treatment outcome; predictors of remission and relapse. Retrospective analysis of medical records of 56 patients with juvenile hyperthyroidism seen over a period of 16 years. A cohort of 38 females and 18 males with mean (+/-SD) age of 14.9 +/- 3.4 years (range 3 to 18 years) was analyzed. Majority of patients was in the age group of 12-16 years. Common symptoms observed at presentation were weight loss (82.1%), excessive sweating (78.6%), heat intolerance (76.8%), increased appetite (73.2%) and diarrhea in 48.2%. In addition, accelerated linear growth was observed in 7.1% of patients. Goiter was present in 98.2% of children; 94.5% of which was diffuse and 4.8% was multinodular. The mean ((+/-SD) T3 was 4.8 +/- 3.4 ng/mL (N, 0.6-1.6), T4 was 218 +/- 98 ng/mL (N, 60-155) and TSH was 0.44 +/- 0.36 (N, 0.5-5.5 microIU/mL). TMA positivity seen in 36.9% of patients. All patients were treated with carbimazole; subsequently 4 patients required thyroidectomy and one required radioactive iodine ablation. Mean (+/-SD) duration of follow-up in our patients was 4.9 +/- 3 years, ranging between 1.6 to 16 years and mean (+/-SD) duration of treatment was 34.4 +/- 22.6 months (range 12 to 120 months). Mean (+/-SD) duration to achieve euthyroidism was 5.2 +/- 4.7 months, ranging between 1-33 months. On intention to treat analysis, remission with carbimazole was achieved in 47.6%, remaining patients failed to achieve remission with drug treatment. Graves disease is the commonest cause of juvenile hyperthyroidism. Carbimazole is safe, effective, cheap, and easily available form of therapy. It is occasionally associated with serious side effects but requires prolonged follow up.

Surface microstructural features of scales in relation to toxic stress of Basic Violet-1.

PubMed

Kaur, Kirandeep; Kaur, Ramandeep; Kaur, Arvinder

2016-01-01

The present work deals with scanning electron microscopic (SEM) studies of the scales of Labeo rohita on exposure to lethal and sublethal doses of Basic Violet-1 (an important textile and hair colorant). The dye induced loosening of the scales and caused breakage and disorganization of lepidonts. Erosion of lepidonts occurred mostly in the fish exposed to 0.20 and 0.40 mg/L dye, during acute exposure and to 0.0225 and 0.045 mg/L dye, during the subchronic exposure. However, lepidonts were sloughed off from their sockets in 0.60 and 0.80 mg/L dye during acute exposure and in 0.09 mg/L dye during the subchronic exposure. Circuli, the base that provides anchorage to the lepidonts, got damaged, and tubercles responsible for coloration of a fish became atrophied with an increase in the duration of exposure. The results of the present investigation clearly indicated that exposure to Basic Violet-1 (BV-1) even at a concentration as low as 0.0225 mg was responsible for deleterious changes in the scale morphology of the test fish after 150 days of exposure. Similar changes were observed in the scales of the dead fish also. It can thus be suggested that this noninvasive technique is very helpful for evaluating the health status of an aquatic body. At the same time, the changes in ultramorphology of scales can act as an early indicator of the stress of very minute doses of dyes and even the scales of a dead fish can act as indicators of the untoward changes that would have occurred in the environment of the fish before death.

[Domestic violence, parenting styles and well-being of German and Turkish juveniles].

PubMed

Uslucan, Haci-Halil

2009-01-01

This intercultural comparative study tries to identify the influences of domestic violence and parenting styles on juvenile violence and the well-being of juveniles. To this end, 304 German and 214 Turkish pupils in Berlin at the age of 13 to 16 completed a standardised questionnaire in their schools. The results show that Turkish juveniles report more harsh parenting styles than their German age-mates, but by controlling statistically the educational background of the parents, these differences disappear. Nevertheless, as a stable finding, we can hold that Turkish parents demand from their children a more cultural appropriate and disciplined behaviour. Furthermore, regarding the rates of juvenile violence, the main differences are seen in violence-legitimating attitudes and witnessing parental violence in the Turkish group. Lastly, in the relations between parenting styles and violence, there seems to be no culturally different patterns, but more differences in the intensity of disadvantaging consequences of punishing and harsh parenting on the well-being of juveniles.

Juvenile-specific cathepsin proteases in Fasciola spp.: their characteristics and vaccine efficacies.

PubMed

Meemon, Krai; Sobhon, Prasert

2015-08-01

Fasciolosis, caused by Fasciola hepatica and Fasciola gigantica, is one of the most neglected tropical zoonotic diseases. One sustainable control strategy against these infections is the employment of vaccines that target proteins essential for parasites' invasion and nutrition acquiring processes. Cathepsin proteases are the most abundantly expressed proteins in Fasciola spp. that have been tested successfully as vaccines against fasciolosis in experimental as well as large animals because of their important roles in digestion of nutrients, invasion, and migration. Specifically, juvenile-specific cathepsin proteases are the more effective vaccines because they could block the invasion and migration of juvenile parasites whose immune evasion mechanism has not yet been fully developed. Moreover, because of high sequence similarity and identity of cathepsins from juveniles with those of adults, the vaccines can attack both the juvenile and adult stages. In this article, the characteristics and vaccine potentials of juvenile-specific cathepsins, i.e., cathepsins L and B, of Fasciola spp. were reviewed.

Analysis of heavy metals from water, sediment, and tissues of Labeo angra (Hamilton, 1822), from an Ox-box lake- an wetland site from Assam, India.

Das, Suchismita; Choudhury, Shamim Sultana

The aim of this study was to assess the regional impacts of heavy metals (Mn, Fe, Mg, Ca, Cu, Zn, Cd, Cr, Pb and Ni) on water, sediment and a native, teleost fish species, Labeo angra, inhabiting a flood plain wetland of Barak River in Assam, India. Heavy metal concentrations in the water, sediments and fish were measured; bioaccumulation factor, metal pollution index as well as condition indices were calculated, to assess the pollution load and health status of the fish. Multivariate statistical analysis was used on wetland water and sediment heavy metals to ascertain the possible sources and seasonal variations of the pollutants. Results showed that most heavy metals in the wetland water and sediments exceeded the water (drinking and irrigation) and sediment quality guidelines, respectively. Seasonal variations were observed for geogenic heavy metals, Mn, Fe, Mg and Ca while no seasonal variations were observed for anthropogenic heavy metals, Cu, Cd, Cr, Pb and Ni. Multivariate statistical analysis showed that there was strong correlation between geogenic and anthropogenic heavy metals in water and sediment, both originating from the common anthropogenic sources. Accumulation of most of the metals in all the tissues was above the safe limits as recommended by the Food and Agriculture Organization. High bioaccumulation factors and metal pollution index for these metals in the different tissues revealed that metals were extensively bio-accumulated and bioconcentrated. Condition indices in fish from the wetland suggested metabolic abnormalities.

The energy production of juvenile Arenicola marina (Polychaeta) under anoxic and hypoxic conditions

NASA Astrophysics Data System (ADS)

Schiedek, Doris; Schöttler, Udo

1990-06-01

The mode of anaerobic energy production of juvenile Arenicola marina (0-generation) was investigated under experimental conditions and in the biotope. Under experimental anaerobic conditions, juvenile A. marina produce energy by the pathways known from the adults and other euryoxic invertebrates with succinate and the volatile fatty acids, acetate and propionate, as main end products. However, the juvenile lugworms are less resistent to anoxia than the adults. The reasons for this might be their small glycogen stores and their limited ability to reduce the metabolic rate. Nevertheless, on the tidal flats the juveniles settle particularly in the area next to the high tide line, which offers such extreme conditions that adult lugworms cannot live there. This different behaviour can be explained by the dissimilar ability to use oxygen at very low partial pressures. Juveniles maintain an aerobic energy metabolism even at a PWO 2 of 15 Torr at which adults are forced to produce energy exclusively by the less effective anaerobic mode. In the field, no indications of an anaerobic energy metabolism were detected in juveniles even after an exposure of 8 hours.

Juvenile xanthogranuloma: a rare cause of subglottic cyst and stenosis.

PubMed

Sahhar, Hanna S; Marra, Silvio; Shahid, Ramzan; Akhter, Javeed

2003-09-01

Only two cases of juvenile xanthogranuloma of the larynx have been previously reported in the literature. We report a new case, which occurred in an 18-month-old girl. The patient was brought to us for treatment of stridor and respiratory distress. During examination, she was found to have a subglottic mass. The lesion was treated with laser microlaryngoscopy, which relieved the patient's respiratory distress and obviated the need for tracheotomy. Pathologic examination of the mass revealed that it was consistent with a juvenile xanthogranuloma. Juvenile xanthogranuloma is generally a benign and self-limiting disease, but complications can occur when the space that the tumor occupies causes functional impairment.

The case of juvenile polygraphy as a clinical ethics dilemma.

PubMed

Chaffin, Mark

2011-09-01

Polygraph interrogations are used by half of all surveyed juvenile sex offender (JSO) treatment programs in the United States. This is a distinctive and controversial practice that is rarely if ever used with other juvenile delinquent populations, and that is rarely used or is banned from JSO treatment programs in other countries. Clinical polygraphy is an ethically sensitive issue because it involves mental health therapists in involuntary coercive interrogations of minors. This article reviews core mental health professional ethics principles for juveniles. JSO polygraphy is used as an illustrative issue for applying human rights principles to a practice in light of its benefits, risks, and available alternatives.

The Importance of Juvenile Root Traits for Crop Yields

Genetic variation in root system architecture (RSA) is an under-exploited breeding resource. This is partly a consequence of difficulties in the rapid and accurate assessment of subterranean root systems. However, although the characterisation of root systems of large plants in the field are both time-consuming and labour-intensive, high-throughput (HTP) screens of root systems of juvenile plants can be performed in the field, glasshouse or laboratory. It is hypothesised that improving the root systems of juvenile plants can accelerate access to water and essential mineral elements, leading to rapid crop establishment and, consequently, greater yields. This presentation will illustrate how aspects of the juvenile root systems of potato (Solanum tuberosum L.) and oilseed rape (OSR; Brassica napus L.) correlate with crop yields and examine the reasons for such correlations. It will first describe the significant positive relationships between early root system development, phosphorus acquisition, canopy establishment and eventual yield among potato genotypes. It will report the development of a glasshouse assay for root system architecture (RSA) of juvenile potato plants, the correlations between root system architectures measured in the glasshouse and field, and the relationships between aspects of the juvenile root system and crop yields under drought conditions. It will then describe the development of HTP systems for assaying RSA of OSR seedlings, the identification of genetic loci affecting RSA in OSR, the development of mathematical models describing resource acquisition by OSR, and the correlations between root traits recorded in the HTP systems and yields of OSR in the field.

The active involvement of parents - whether as recipients, extenders, or managers of services - during their youth's experience with the juvenile justice system is widely assumed to be crucial. Parents and family advocacy groups note persisting concerns with the degree to which successful parental involvement is achieved. Justice system providers are highly motivated and actively working to make improvements. These coalescing interests provide a strong motivation for innovation and improvement regarding family involvement, but the likely success of these efforts is severely limited by the absence of any detailed definition of parental involvement or validated measure of this construct. Determining whether and how parental involvement works in juvenile justice services depends on the development of clear models and sound measurement. Efforts in other child serving systems offer guidance to achieve this goal. A multidimensional working model developed with parents involved in child protective services is presented as a template for developing a model for parental involvement in juvenile justice. Features of the model requiring changes to make it more adaptable to juvenile justice are identified. A systematic research agenda for developing methods and measures to meet the present demands for enhanced parental involvement in juvenile justice services is presented.

Ozenoxacin is a nonfluorinated quinolone antibacterial approved for topical treatment of impetigo. Because quinolones have known chondrotoxic effects in juvenile animals, the potential toxicity of ozenoxacin was assessed in preclinical studies. Ozenoxacin or ofloxacin (300 mg/kg/day for 5 days, for each compound) was orally administered to juvenile rats, and oral ozenoxacin (10-100 mg/kg/day for 14 days) was administered to juvenile dogs. In juvenile rats, ozenoxacin showed no chondrotoxicity, whereas ofloxacin produced typical quinolone-induced lesions in articular cartilage in three of ten rats. Oral ozenoxacin administration to juvenile dogs showed no chondrotoxicity or toxicologically relevant findings in selected target organs. Ozenoxacin was generally well-tolerated in juvenile rats and dogs, with no evidence of quinolone-induced arthropathy.

Coral bleaching events have caused extensive mortality on reefs around the world. Juvenile corals are generally less affected by bleaching than their conspecific adults and therefore have the potential to buffer population declines and seed recovery. Here, we use juvenile and adult abundance data at 20 sites encircling Lizard Island, Great Barrier Reef, before and after the 2016 bleaching event to quantify: (1) correlates of changes in juvenile abundance following a bleaching event; (2) differences in susceptibility to extreme thermal stress between juveniles and adults. Declines in juvenile abundance were lower at sites closer to the 20-m-depth contour and higher for Acropora and Pocillopora juveniles than for other taxa. Juveniles of Acropora and Goniastrea were less susceptible to bleaching than adults, but the opposite was true for Pocillopora spp. and taxa in the family Merulinidae. Our results indicate that the potential of the juvenile life stage to act as a buffer during bleaching events is taxon-dependent.

Variable expression of molecular markers in juvenile nasopharyngeal angiofibroma.

PubMed

Mishra, A; Pandey, A; Mishra, S C

2017-09-01

Molecular categorisation may explain the wide variation in the clinical characteristics of juvenile nasopharyngeal angiofibroma. Variations in molecular markers in juvenile nasopharyngeal angiofibroma in an Indian population were investigated and compared with global reports. Variable molecular marker expression was demonstrated at the regional and global levels. A wide variation in molecular characteristics is evident. Molecular data have been reported for only 11 countries, indicating a clear geographical bias. Only 58 markers have been studied, and most are yet to be validated. Research into the molecular epidemiology of juvenile nasopharyngeal angiofibroma is still in its infancy. Although the molecular variation is not well understood, data obtained so far have prompted important research questions. Hence, multicentre collaborative molecular studies are needed to establish the aetiopathogenesis and establish molecular surrogates for clinical characteristics.

Effects of natal departure and water level on survival of juvenile snail kites (Rostrhamus sociabilis) in Florida

2004-01-01

Survival rate from fledging to breeding, or juvenile survival, is an important source of variation in lifetime reproductive success in birds. Therefore, determining the relationship between juvenile survival and environmental factors is essential to understanding fitness consequences of reproduction in many populations. With increases in density of individuals and depletion of food resources, quality of most habitats deteriorates during the breeding season. Individuals respond by dispersing in search of food resources. Therefore, to understand the influence of environmental factors on juvenile survival, it is also necessary to know how natal dispersal influences survival of juveniles. We examined effects of various environmental factors and natal dispersal behavior on juvenile survival of endangered Snail Kites (Rostrhamus sociabilis) in central and southern Florida, using a generalized estimating equations (GEEs) approach and model selection criteria. Our results suggested yearly effects and an influence of age and monthly minimum hydrologic levels on juvenile Snail Kite survival. Yearly variation in juvenile survival has been reported by other studies, and other reproductive components of Snail Kites also exhibit such variation. Age differences in juvenile survival have also been seen in other species during the juvenile period. Our results demonstrate a positive relationship between water levels and juvenile survival. We suggest that this is not a direct linear relationship, such that higher water means higher juvenile survival. The juvenile period is concurrent with onset of the wet season in the ecosystem we studied, and rainfall increases as juveniles age. For management purposes, we believe that inferences suggesting increasing water levels during the fledging period will increase juvenile survival may have short-term benefits but lead to long-term declines in prey abundance and possibly wetland vegetation structure.

Contrasting movement strategies among juvenile albatrosses and petrels

de Grissac, Sophie; Börger, Luca; Guitteaud, Audrey; Weimerskirch, Henri

2016-05-01

Animal movement is a fundamental eco-evolutionary process yet the behaviour of juvenile animals is largely unknown for many species, especially for soaring seabirds which can range widely over the oceans at low cost. We present an unprecedented dataset of 98 juvenile albatrosses and petrels (nine species), tracked for the first three months after independence. There was a startling diversity within and among species in the type and scale of post-natal movement strategies, ranging from area-restricted to nomadic patterns. Spatial scales were clustered in three groups that ranged from <3000 km to >6000 km from the natal nest. In seven of the nine species, the orientation of flight paths and other movement statistics showed strong similarities between juveniles and adults, providing evidence for innate orientation abilities. Our results have implications for understanding the development of foraging behaviour in naïve individuals and the evolution of life history traits such as survival, lifespan and breeding strategy.

Spirituality, adolescent suicide, and the juvenile justice system.

PubMed

Wahl, Richard A; Cotton, Sian; Harrison-Monroe, Patricia

2008-07-01

Spirituality is often overlooked as a coping method and resilience factor in the lives of adolescents. An improved understanding of the role of spirituality in the lives of adolescents will help in understanding the choices many teens face during times of personal crisis. Youth entering the juvenile justice system often present with high rates of mental health problems and suicidal ideation. Two clinical vignettes of adolescents who exhibited suicidal ideation while in juvenile detention are discussed. An understanding of the role of spirituality for an adolescent in crisis can greatly enhance our ability to provide culturally competent care and offer meaningful support. This becomes increasingly important as the juvenile detention population becomes ever more diverse. Valuable information can be obtained by taking a "clinical spiritual history" which enables clinicians to have a clearer understanding of an adolescent's worldview and provide the necessary therapeutic interventions. Specific questions are suggested as a basis for obtaining this information.

Applying Roper v. Simmons in juvenile transfer and waiver proceedings: a legal and neuroscientific inquiry.

PubMed

Fabian, John Matthew

2011-08-01

In 2005, the U.S. Supreme Court held the death penalty unconstitutional as applied to juveniles in Roper v. Simmons. The Court reasoned that juveniles were less criminally culpable than adults because they lack maturity, they are more vulnerable to peer influence, and their character is not as well formed as that of adults. Although Roper addressed the imposition of the ultimate punishment of death within the context of a juvenile's moral blameworthiness for a crime of murder, this article considers the application of the Court's reasoning in Roper to the issue of juvenile waiver. Specifically, the author asks the question whether Roper's ultimate language distinguishing juveniles from adults in capital cases should apply to the conventional practice of their trial and sentencing as adults. Despite the fact that juvenile transfer is a less serious sanction than the death penalty, this inquiry confronts the traditional objective of the juvenile court system, a system of punishment that was founded on rehabilitation rather than retribution. The author questions whether the punitive objectives of deterrence and retribution are satisfied by juvenile waiver and whether the mitigating effect of adolescence negates the trial of youth as adults.

Exploring the role of the internet in juvenile prostitution cases coming to the attention of law enforcement.

Wells, Melissa; Mitchell, Kimberly J; Ji, Kai

2012-01-01

This exploratory analysis examines the role of the Internet in juvenile prostitution cases coming to the attention of law enforcement. The National Juvenile Prostitution Study (N-JPS) collected information from a national sample of law enforcement agencies about the characteristics of juvenile prostitution cases. In comparison to non-Internet juvenile prostitution cases, Internet juvenile prostitution cases involved younger juveniles and police were more likely to treat juveniles as victims rather than offenders. In addition, these cases were significantly more likely to involve a family or acquaintance exploiter. This analysis suggests that the role of the Internet may impact legal and social service response to juveniles involved in prostitution. In addition, it highlights the need for interventions that acknowledge the vulnerabilities of youth involved in this type of commercial sexual exploitation.

2013-07-01

Juvenile nasopharyngeal angiofibroma is a histologically benign, but very aggressive and destructive tumor found exclusively in young males. The management of juvenile nasopharyngeal angiofibroma has changed in recent years, but it still continues to be a challenge for the multidisciplinary head and neck surgical team. The purpose of this study was to review a series of 30 patients describing the treatment approach used and studying the outcome of juvenile nasopharyngeal angiofibroma in the ENT Department Timisoara, Romania for a period of 30 years. The patients were diagnosed and treated during the years 1981-2011. All patients were male. Tumors were classified using Radkowski's staging system. Computed tomography and magnetic resonance imaging allowed for accurate diagnosis and staging of the tumors. Biopsies were not performed. Surgery represented the gold standard for treatment of juvenine nasopharyngeal angiofibroma. All patients had the tumor removed by an external approach, endoscopic surgical approach not being employed in this series of patients. All patients were treated surgically. Surgical techniques performed were: Denker-Rouge technique in 13 cases (43.33%), paralateronasal technique in 7 cases (23.33%), retropalatine technique in 5 cases (16.66%) and transpalatine technique in 5 cases (16.66%). No preoperative tumor embolization was performed. The recurrence rate was 16.66%. The follow-up period ranged from 1 year to 12 years. Management of juvenile nasopharyngeal angiofibroma remains a surgical challenge. Clinical evaluation and surgical experience are very important in selecting the proper approach. A multidisciplinary team, with an experienced surgeon and good collaboration with the anesthesiologist are needed for successful surgical treatment. Copyright © 2013 Elsevier Ireland Ltd.

Juvenile idiopathic arthritis is a systemic pathology of connective tissue characterized by a chronic inflammatory process with an autoimmune background whereas multiple sclerosis is a demyelination disease with an important role of immune disorders in its pathogenesis. The etiology in both cases remains unknown. The coincidence of juvenile idiopathic arthritis and multiple sclerosis was described a just a few patients. We now report on a 31-year-old woman with juvenile idiopathic arthritis and multiple sclerosis. In the present case, the main problem was to find the right proper medication for a very, aggressive course of multiple sclerosis and for arthritis. Treatment with interferon-beta and methylprednisolone led to remission with just minor side-effects.

Juvenile-adult habitat shift in permian fossil reptiles and amphibians.

PubMed

Bakker, R T

1982-07-02

Among extant large reptiles, juveniles often occupy different habitats from those of adults or subadults and thus avoid competition with and predation from the older animals; small juveniles often choose cryptic habitats because they are vulnerable to a wide variety of predators. Evidence from fossil humeri and femora of Early Permian reptiles collected from sediments of several distinct habitats indicate that similar shifts in habitat occurred. Juvenile Dimetrodon seem to have favored cryptic habitats around swamp and swampy lake margins; adults favored open habitats on the floodplains. Similar patterns of habitat shift seem to be present in the reptile Ophiacodon and the amphibian Eryops and may have been common in fossil tetrapods of the Permian-Triassic.

Juvenile justice. A role for health professionals.

PubMed

Brookman, Monica

2003-01-01

The United States is the only nation in the world that continues to execute its youth. The use of the death penalty against those who committed crimes as children is an act contrary to American standards of decency and fairness, as well as international law. The adolescent brain has not fully developed before the age of 18 years of age. Thus children do not have the same emotional and mental capacity as adults. Although juveniles should be held accountable for their crimes, the United States must not impose this most extreme punishment. The medical profession must take a stand to stop the execution of juvenile offenders in the United States.

Adolescents involved with the juvenile justice system have higher rates of risky sexual behaviors, resulting in high rates of sexually transmitted infections and increased risk of human immunodeficiency virus, early or complicated pregnancy, and parenting issues. Comorbid substance abuse, gang association, mental health issues, and history of having been abused as children result in further elevated rates. Girls and lesbian, gay, bisexual, and transgender youths represent growing subpopulations with special risks. Increasingly diverted to community-based alternatives, juvenile justice-involved teens obtain most of their medical care from community providers, who need to understand their risks to provide appropriate, optimal care.

2016-01-01

Research on juvenile justice aims to identify profiles of risk and protective factors in juvenile offenders. This paper presents a study of profiles of risk factors that influence young offenders toward committing sanctionable antisocial behavior (S-ASB). Decision tree analysis is used as a multivariate approach to the phenomenon of repeated sanctionable antisocial behavior in juvenile offenders in Spain. The study sample was made up of the set of juveniles who were charged in a court case in the Juvenile Court of Almeria (Spain). The period of study of recidivism was two years from the baseline. The object of study is presented, through the implementation of a decision tree. Two profiles of risk and protective factors are found. Risk factors associated with higher rates of recidivism are antisocial peers, age at baseline S-ASB, problems in school and criminality in family members. PMID:27611313

Schillaci, Michael A; Nikitovic, Dejana; Akins, Nancy J; Tripp, Lianne; Palkovich, Ann M

2011-06-01

The present study examines patterns of infant and juvenile growth in a diachronic sample of ancestral Pueblo Indians (AD 1300-1680) from the American Southwest. An assessment of growth patterns is accompanied by an evaluation of pathological conditions often considered to be indicators of nutritional deficiencies and/or gastrointestinal infections. Growth patterns and the distribution of pathological conditions are interpreted relative to culturally relevant age categories defined by Puebloan rites of passage described in the ethnographic literature. A visual comparison of growth distance curves revealed that relative to a modern comparative group our sample of ancestral Pueblo infant and juveniles exhibited faltering growth beginning soon after birth to about 5 years of age. A comparison of curves describing growth relative to adult femoral length, however, indicated reduced growth occurring later, by around 2 years of age. Similar to previous studies, we observed a high proportion of nonsurvivors exhibiting porotic cranial lesions during the first 2 years of life. Contrary to expectations, infants and juveniles without evidence of porotic cranial lesions exhibited a higher degree of stunting. Our study is generally consistent with previous research reporting poor health and high mortality for ancestral Pueblo Indian infants and juveniles. Through use of a culturally relevant context defining childhood, we argue that the observed poor health and high mortality in our sample occur before the important transition from young to older child and the concomitant initial incorporation into tribal ritual organization.

Double helix: reciprocity between juvenile play and brain development.

PubMed

Cooke, Bradley M; Shukla, Deep

2011-10-01

This review summarizes what is presently known about the function, sexual differentiation, and neural circuitry of juvenile rough-and-tumble play. Juvenile rough-and-tumble play is a unique motivated behavior that is widespread throughout the mammalian order and usually occurs more often in males. Immediate early gene studies indicate that cortical and subcortical circuits, many of which are sensitive to sex steroid hormones, mediate juvenile play. Sex differences in rough-and-tumble play are controlled in part by neonatal exposure to androgens or their estrogenic metabolites. Studies indicate that testicular androgens during play are also necessary to stimulate male-like levels of play initiation. The resemblance of rough-and-tumble play to aggression and sexual behavior has led some to question whether male-typical adult behavior is contingent upon the experience of play. Attempts to control the amount of play through social isolation show that social experience during adolescence is critical for male-typical adult behaviors to be expressed. This well-established finding, together with evidence that play induces neural plasticity, supports the hypothesis that juvenile play contributes to male-typical brain development that ultimately enables the expression of adult social and reproductive behavior.

The distinction between juvenile and adult-onset primary open-angle glaucoma

DOE Office of Scientific and Technical Information (OSTI.GOV)

Wiggs, J.L.; Haines, J.L.; Damji, K.F.

1996-01-01

Because of the significant differences between the juvenile and adult forms of open-angle glaucoma, especially with regard to inheritance, prevalence, severity, and age of onset, we read with interest the recent publication by Morissette et al., describing a pedigree with a phenotype that overlaps the distinctive features of juvenile-onset open-angle glaucoma (JOAG) and adult-onset primary open-angle glaucoma (usually abbreviated as POAG or COAG). These authors conclude that a gene mapped to human chromosome 1q21-q31 (GLC1A) can be responsible for both juvenile and adult forms of open-angle glaucoma. The implications of such a result could be extremely important, in light ofmore » the high prevalence of the adult form of the disease. However, while the data presented in this report suggest that variable expressivity of the GLC1A gene may lead to a broader range of onset for this form of juvenile glaucoma, these data do not identify the GLC1A gene as an important cause of POAG. To prevent misleading interpretations of this and similar studies, we wish to clarify the distinction between the juvenile and adult forms of open-angle glaucoma. 8 refs.« less

Systemic juvenile idiopathic arthritis is a rare febrile arthritis of childhood characterized by a potentially severe course, including prolonged glucocorticoid exposure, growth failure, destructive arthritis, and life-threatening macrophage activation syndrome. Early cytokine-blocking biologic therapy may improve long-term outcomes, although some systemic juvenile idiopathic arthritis patients respond well to non-biologic treatment, leaving optimal management undefined. Consequently, treatment of new-onset systemic juvenile idiopathic arthritis by expert clinicians varies widely. To describe a pragmatic, observational comparative effectiveness study that takes advantage of diversity in the management of a rare disease: FiRst-Line Options for Systemic juvenile idiopathic arthritis Treatment (FROST), comparing non-biologic and biologic consensus treatment plans for new-onset systemic juvenile idiopathic arthritis within the 60-center Childhood Arthritis and Rheumatology Research Alliance Registry (CARRA). FiRst-Line Options for Systemic juvenile idiopathic arthritis Treatment (FROST) is a multicenter, prospective, non-randomized study that compares four Childhood Arthritis and Rheumatology Research Alliance (CARRA) consensus treatment plans for new-onset systemic juvenile idiopathic arthritis: (1) glucocorticoids alone, (2) methotrexate, (3) interleukin-1 blockade, and (4) interleukin-6 blockade. Patients consenting to participation in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry are started on one of four Consensus Treatment Plans at the discretion of the treating physician. The outcome of primary interest is clinically inactive disease off glucocorticoids at 9 months, comparing non-biologic (Consensus Treatment Plans 1 + 2) versus biologic (Consensus Treatment Plans 3 + 4) strategies. Bayesian analytic methods will be employed to evaluate response rates, using propensity scoring to balance treatment groups for potential

2015-01-01

Context Automobile crashes cause more than 800,000 youth injuries and deaths each year. Other youth suffer the consequences from being either a perpetrator or victim of a crime. One type of law that has an effect on youth behavior is juvenile curfew laws. These laws restrict the times that youth may occupy public places or streets. We systematically reviewed studies evaluating the effectiveness of these laws to address the question: Can juvenile curfew laws be used to improve youth public health and juvenile justice outcomes? Evidence acquisition In 2013, we used a standardized set of keywords to search 24 databases for studies that evaluated effectiveness outcome measures of juvenile curfew laws. After applying the exclusion criteria and removing duplicate studies, 14 studies of juvenile curfews remained. Evidence synthesis Of the six studies examining the effectiveness of juvenile curfew laws on adverse youth health outcomes, five found a positive impact. Of the eight studies examining the effectiveness of curfew laws on juvenile crime and victimization, four found a positive impact. Conclusions The studies that found that juvenile curfew laws were effective at reducing adverse youth health outcomes (e.g., trauma transports), juvenile crime, and victimization were of higher quality (e.g., stronger methodologic approaches) than those finding no effects. However, given the limited number of studies and concerns with quality, we conclude that more research is needed before conclusions can be drawn about the effectiveness of juvenile curfew laws.

Relatively little is known about the substance abuse treatment need patterns and experiences of youth incarcerated in the United States juvenile justice system. To address this issue, four analytic questions concerned with understanding the predictors of treatment need and utilization patterns among adolescents entering the juvenile corrections system are examined. Data analyzed were collected as part of a face-to-face survey of 401 youth who entered the Illinois juvenile correctional system in mid-2000. Overall, need for treatment and treatment utilization each were predicted by sets of social environmental and personal characteristics, in addition to several sociodemographic variables. Less than half of youth with an identified need for treatment reported receiving treatment. Considerable variability in the effects of demographic and social environmental indicators on treatment need and utilization across race groups also was observed. These findings underscore the need for the continual development of the cultural competence of treatment providers and the expansion of on-site provision of substance abuse treatment services to incarcerated juveniles.

Juvenile xanthogranuloma of the corneoscleral limbus: case report and review of the literature.

Juvenile xanthogranuloma is a benign histiocytic cutaneous disorder mainly occurring in infants which may affect the eye. Ocular manifestations usually present in the form of iris lesions with secondary hyphema and glaucoma, but juvenile xanthogranuloma may also present as a corneoscleral limbal mass. We present the case of an 18-month-old female infant with ocular juvenile xanthogranuloma occurring as a corneoscleral limbal mass without associated cutaneous or systemic findings. The limbal mass lesion was excised by lamellar dissection and histopathological studies revealed histiocytes admixed with lymphocytes, plasma cells, and eosinophils; foreign body and Touton giant cells present throughout the specimen confirmed the diagnosis of juvenile xanthogranuloma. At 14-month follow-up, there was no recurrence of the limbal mass. The natural history of this uncommon ocular condition is discussed and the relevant literature reviewed. Juvenile xanthogranuloma should be considered in the differential diagnosis of any corneoscleral limbal mass lesion, particularly in children.

Foraging behaviour of juvenile female New Zealand sea lions (Phocarctos hookeri) in contrasting environments.

2013-01-01

Foragers can show adaptive responses to changes within their environment through morphological and behavioural plasticity. We investigated the plasticity in body size, at sea movements and diving behaviour of juvenile female New Zealand (NZ) sea lions (Phocarctos hookeri) in two contrasting environments. The NZ sea lion is one of the rarest pinnipeds in the world. Most of the species is based at the subantarctic Auckland Islands (AI; considered to be marginal foraging habitat), with a recolonizing population on the Otago Peninsula, NZ mainland (considered to be more optimal habitat). We investigated how juvenile NZ sea lions adjust their foraging behaviour in contrasting environments by deploying satellite-linked platform transmitting terminals (PTTs) and time-depth recorders (TDRs) on 2-3 year-old females at AI (2007-2010) and Otago (2009-2010). Juvenile female NZ sea lions exhibited plasticity in body size and behaviour. Otago juveniles were significantly heavier than AI juveniles. Linear mixed effects models showed that study site had the most important effect on foraging behaviour, while mass and age had little influence. AI juveniles spent more time at sea, foraged over larger areas, and dove deeper and longer than Otago juveniles. It is difficult to attribute a specific cause to the observed contrasts in foraging behaviour because these differences may be driven by disparities in habitat/prey characteristics, conspecific density levels or interseasonal variation. Nevertheless, the smaller size and increased foraging effort of AI juveniles, combined with the lower productivity in this region, support the hypothesis that AI are less optimal habitat than Otago. It is more difficult for juveniles to forage in suboptimal habitats given their restricted foraging ability and lower tolerance for food limitation compared to adults. Thus, effective management measures should consider the impacts of low resource environments, along with changes that can alter food

The psycholegal factors for juvenile transfer and reverse transfer evaluations.

King, Christopher M

2018-01-01

It remains unclear whether forensic mental health assessments for juvenile reverse transfer (to juvenile court) are distinct from those for juvenile transfer (to adult court). This survey consisted of an updated review of transfer and reverse transfer laws (in jurisdictions that have both mechanisms) in light of the generally accepted three-factor model of functional legal capacities involved in transfer evaluations (i.e., risk, sophistication-maturity, and treatment amenability). Results indicated that a majority of states' reverse transfer statutes refer explicitly or implicitly to the same three psycholegal constructs identified as central for transfer. Given the legal similarity between transfer and reverse transfer, potential practice implications and directions for future research are discussed. Copyright © 2017 John Wiley & Sons, Ltd.

This integrative review summarizes nursing researches that contribute to study juvenile obesity with a focus on health promotion. 20 articles were identified in a bibliographical survey that followed the criteria: date, language, and the descriptors: nursing, adolescent, obesity and health promotion. The Pediatric Nursing Journal published seven of these papers (35%). Indexed papers were published in the last ten years in Portuguese and English. Results showed the construction of scientific knowledge in nursing that developed health promotion strategies in cases of juvenile obesity, thus contributing to the development of the profession. Showing the cumulative risk that juvenile obesity presents of turning subjects into obese adults is a precious resource to plan nursing actions for this population, and for these actions to achieve effective results.

Adverse juvenile experiences, including physical abuse, often have negative health consequences later in life. We investigated the influence of social defeat stress exposure as juveniles on neuropsychological behaviors, and the causal role of glucocorticoids in abnormal behaviors and impairment of neurogenesis in mice exposed to the stress. The juvenile (24-day-old) and adult (70-day-old) male C57BL/6J mice were exposed to social defeat stress induced by an aggressive ICR mouse. Social defeat stress exposure as juveniles, even for 1 day, induced persistent social avoidance to the unfamiliar ICR mouse in the social interaction test, but that was not observed in mice exposed to the stress as adults. Social avoidance by the stress exposure as juveniles for 10 consecutive days was observed, when the target mouse was not only unfamiliar ICR but also another C57BL/J mouse, but not an absent or an anesthetized ICR mouse. The stress exposure did not induce anxiety- and depression-like behaviors in spontaneous locomotor activity, elevated plus-maze test, marble-burying test, forced swimming test, or sucrose preference test. Serum corticosterone levels increased immediately after the stress exposure. The hippocampal neurogenesis was suppressed 1 day and 4 weeks after the stress exposure. Administration of mifepristone, a glucocorticoid receptor antagonist, prior to each stress exposure, blocked the persistent social avoidance and suppression of neurogenesis. In conclusion, social avoidance induced by social defeat stress exposure as juveniles are more persistent than that as adults. These social avoidances are associated with suppression of hippocampal neurogenesis via glucocorticoid receptors. Copyright © 2018 Elsevier Ltd. All rights reserved.

The effect of excluding juveniles on apparent adult olive baboons (Papio anubis) social networks

PubMed Central

Fedurek, Piotr; Lehmann, Julia

2017-01-01

In recent years there has been much interest in investigating the social structure of group living animals using social network analysis. Many studies so far have focused on the social networks of adults, often excluding younger, immature group members. This potentially may lead to a biased view of group social structure as multiple recent studies have shown that younger group members can significantly contribute to group structure. As proof of the concept, we address this issue by investigating social network structure with and without juveniles in wild olive baboons (Papio anubis) at Gashaka Gumti National Park, Nigeria. Two social networks including all independently moving individuals (i.e., excluding dependent juveniles) were created based on aggressive and grooming behaviour. We used knockout simulations based on the random removal of individuals from the network in order to investigate to what extent the exclusion of juveniles affects the resulting network structure and our interpretation of age-sex specific social roles. We found that juvenile social patterns differed from those of adults and that the exclusion of juveniles from the network significantly altered the resulting overall network structure. Moreover, the removal of juveniles from the network affected individuals in specific age-sex classes differently: for example, including juveniles in the grooming network increased network centrality of adult females while decreasing centrality of adult males. These results suggest that excluding juveniles from the analysis may not only result in a distorted picture of the overall social structure but also may mask some of the social roles of individuals belonging to different age-sex classes.

Behavioral and neuroendocrine consequences of juvenile stress combined with adult immobilization in male rats.

PubMed

Fuentes, Silvia; Carrasco, Javier; Armario, Antonio; Nadal, Roser

2014-08-01

Exposure to stress during childhood and adolescence increases vulnerability to developing several psychopathologies in adulthood and alters the activity of the hypothalamic-pituitary-adrenal (HPA) axis, the prototypical stress system. Rodent models of juvenile stress appear to support this hypothesis because juvenile stress can result in reduced activity/exploration and enhanced anxiety, although results are not always consistent. Moreover, an in-depth characterization of changes in the HPA axis is lacking. In the present study, the long-lasting effects of juvenile stress on adult behavior and HPA function were evaluated in male rats. The juvenile stress consisted of a combination of stressors (cat odor, forced swim and footshock) during postnatal days 23-28. Juvenile stress reduced the maximum amplitude of the adrenocorticotropic hormone (ACTH) levels (reduced peak at lights off), without affecting the circadian corticosterone rhythm, but other aspects of the HPA function (negative glucocorticoid feedback, responsiveness to further stressors and brain gene expression of corticotrophin-releasing hormone and corticosteroid receptors) remained unaltered. The behavioral effects of juvenile stress itself at adulthood were modest (decreased activity in the circular corridor) with no evidence of enhanced anxiety. Imposition of an acute severe stressor (immobilization on boards, IMO) did not increase anxiety in control animals, as evaluated one week later in the elevated-plus maze (EPM), but it potentiated the acoustic startle response (ASR). However, acute IMO did enhance anxiety in the EPM, in juvenile stressed rats, thereby suggesting that juvenile stress sensitizes rats to the effects of additional stressors.

The triple association between juvenile xanthogranuloma (JXG), juvenile myelomonocytic leukemia and neurofibromatosis was described in literature in about 20 cases. In this paper, the case of an 11-month-old infant boy with a disseminated JXG with unusual cytogenetic representation in the bone marrow was reported. Neurofibromatosis and juvenile myelomonocytic leukemia were excluded, just the same as other leukemias. Bone marrow and peripheral blood cytogenetic analysis revealed a karyotype with many rearrangements 46,XY,-6,der(12)t(6;12)(p21;p13),del(7)(p13p22),+9 once described in the literature as a B-acute lymphoblastic leukemia case. On the contrary, in our patient immunologic testing demonstrated a high activity of T lymphocytes, however, inflammation was excluded. To the best of our knowledge this is the first described case of systemic JXG with determined karyotype representing unusual chromosomal aberrations.

Juvenile social experience affects pairing success at adulthood: congruence with the loser effect?

Social interactions with adults are often critical for the development of mating behaviours. However, the potential role of other primary social partners such as juvenile counterparts is rarely considered. Most interestingly, it is not known whether interactions with juvenile females improve males’ courtship and whether, similar to the winner and loser effects in a fighting context—outcome of these interactions shapes males’ behaviour in future encounters. We investigated the combined effects of male quality and juvenile social experience on pairing success at adulthood in zebra finches (Taeniopygia guttata). We manipulated brood size to alter male quality and then placed males in either same- or mixed-sex juvenile dyads until adulthood. We found that males from reduced broods obtained more copulations and males from mixed-sex dyads had more complete courtships. Furthermore, independent of their quality, males that failed to pair with juvenile females, but not juvenile males, had a lower pairing success at adulthood. Our study shows that negative social experience with peers during adolescence may be a potent determinant of pairing success that can override the effects of early environmental conditions on male attractiveness and thereby supports the occurrence of an analogous process to the loser effect in a mating context.

The impacts of ocean acidification have only recently been recognized as a human-induced stressor on marine ecosystems. Ocean acidification can disrupt calcification in organisms that precipitate calcareous structures, including many ecologically and economically important species. We examined how decreased levels of carbonate saturation affected larval and juvenile growth and settlement in the native oyster Ostrea lurida. Larvae were cultured at three carbonate saturation levels that represent present day CO2 concentrations (380 ppm) and two future projected pCO2 scenarios (540 and 970 ppm). These treatments were maintained for 20 days throughout larval duration until settlement occurred. Larval and juvenile growth were determined by calculating change in shell area. Larvae exposed to 970 ppm grew 12% less than larvae held under control conditions (380 ppm). In addition, growth varied among larvae produced by different parents, suggesting that impacts of ocean acidification might vary intraspecifically. Juvenile growth (i.e., new shell added following settlement) was significantly different among CO2 treatments, and juveniles exposed to 970 ppm grew 24% less than juveniles held under control conditions (380 ppm). Carry-over effects from the larval stage influence juvenile growth, and because post-settlement mortality is often high for marine invertebrates, ocean acidification may negatively impact the size of native oyster populations.

There are substantial differences between adults and juveniles in the context of competency restoration. Among juveniles, factors such as maturity level, age, intellectual functioning, and psychiatric diagnoses may affect competency to stand trial. In this study, subjects included all juveniles who were admitted to the Albert J. Solnit Children's Center for inpatient competency restoration in the period spanning January 1, 2005, through December 31, 2012. Sixty-one juveniles were referred during this period, and 58 were included in the final analyses. Several demographic and clinical variables were tested to identify which factors were associated with successful competency restoration. There was a high rate of psychiatric comorbidity in the sample, with 54 of 58 juveniles (93%), having more than one Axis I disorder. IQ was the only significant predictor of successful competency restoration. These findings suggest that cognitive limitations may be a robust predictor of competency restoration among juveniles who are deemed incompetent to stand trial. Furthermore, policy makers may want to consider more specialized services for youths whose intellectual deficits are severe enough to impact their ability to regain competency. Limitations of this study, policy recommendations, and suggestions for future research are discussed. © 2016 American Academy of Psychiatry and the Law.

Serious scholarly inquiry into juvenile sex offending represents a relatively new field, dating from the mid 1940s. During the next 4 decades, a mere handful of articles exploring aspects of juvenile sex offending were added to the available literature. By the 1980s, however, the literature began to increase rapidly, a trend that continues today. The purpose of this article is a focused review of the juvenile sex offender literature cited in PubMed over the last 5 years (2009-2013). The authors have chosen studies that will bring readers up to date on research they believe impacts our current understanding of best practices in the management of juvenile sex offending. For convenience, our review is organized into topical categories including research into characteristics and typologies of juvenile sex offenders, risk assessment and recidivism, assessment and treatment, the ongoing debate about mandatory registration of sex offenders as it applies to juveniles, and other thought provoking studies that do not fit neatly into the aforementioned categories. The studies included contain findings that both reinforce and challenge currently held notions about best practices concerning treatment and public policy, suggesting that our knowledge of the field continues to evolve in important ways.

DNA fingerprint similarity between female and juvenile brown-headed cowbirds trapped together

1995-01-01

This DNA fingerprinting study investigates whether females of the brood parasite brown-headed cowbird, Molothrus ater, associate with their own juvenile offspring at feeding sites more often than would be expected by chance. Cowbirds lay their eggs in the nests of a variety of host species and, as far as is known, leave them to the care of foster parents. Using baited walk-in funnel traps, 36 adult female-juvenile pairs (or trios) of cowbirds were trapped. Blood samples were collected from these individuals to conduct DNA fingerprinting analyses, calculate similarity indices, and to compare S-values for the 11 comparisons of juveniles and the females with which they were caught with S-values of random pairings of juveniles and the females in adjacent gel lanes with which they were not caught. Overall band-sharing was significantly higher for the individuals trapped together than for the random pairings. These associations between juvenile cowbirds and their mothers could occur as a result of female cowbirds monitoring the development of their young in the nests where they have laid. Alternatively, nestling cowbirds in the nest could become familiar visually and locally with a female parent that is frequently in their territory and could follow her when she departs for feeding grounds. In either case these data suggest that adult cowbirds associate with juveniles, in some cases their own offspring, and that offspring may learn to function as cowbirds in part from this association.

Juvenile xanthogranuloma is a rare disorder which may be present at birth, or appears in infancy. It can also occur in adults of all ages; appears with lesions that may be solitary or multiple nodules several millimeters in diameter. The predilection sites are head and neck, but it may occur on the extremities and trunk also. There can also be involved internal organs such as lung, kidney, gastrointestinal tract, etc. The most frequent extracutaneous location is the eye. We report a case of juvenile xanthogranuloma in a male child with onset in the fourth month of life. He presented with a nodule 8 millimeters in diameter, tan-orange in color, ulcerated in the centre, located on the left corner of the left eye. A biopsy without total excision was performed. After the biopsy, the nodule enlarged to 1.5 cm in diameter and became haemorrhagic. The histologic evaluation and immunohistochemistry analysis resulted in the diagnosis of juvenile xanthogranuloma. For aesthetic reasons the nodule was removed by surgical resection. Juvenile xanthogranuloma is on a spectrum of histiocytic disorders, which is necessary to differentiate from maligniances in childhood by biopsy.

Fitness Consequences of Boldness in Juvenile and Adult Largemouth Bass.

Ballew, Nicholas G; Mittelbach, Gary G; Scribner, Kim T

2017-04-01

To date, most studies investigating the relationship between personality traits and fitness have focused on a single measure of fitness (such as survival) at a specific life stage. However, many personality traits likely have multiple effects on fitness, potentially operating across different functional contexts and stages of development. Here, we address the fitness consequences of boldness, under seminatural conditions, across life stages and functional contexts in largemouth bass (Micropterus salmoides). Specifically, we report the effect of boldness on (1) juvenile survivorship in an outdoor pond containing natural prey and predators and (2) adult reproductive success in three outdoor ponds across three reproductive seasons (years). Juvenile survival was negatively affected by boldness, with bolder juveniles having a lower probability of survival than shyer juveniles. In contrast, bolder adult male bass had greater reproductive success than their shyer male counterparts. Female reproductive success was not affected by boldness. These findings demonstrate that boldness can affect fitness differently across life stages. Further, boldness was highly consistent across years and significantly heritable, which suggests that boldness has a genetic component. Thus, our results support theory suggesting that fitness trade-offs across life stages may contribute to the maintenance of personality variation within populations.

2014-01-01

Nailfold capillaroscopy has become an established method in adults for the evaluation of structural abnormalities of the microcirculation associated with rheumatic disease. It is a cornerstone for the diagnostic work-up of patients with Raynaud's phenomenon and the early diagnosis of systemic sclerosis. However, this non-invasive examination may also be valuable in children and adolescents with rheumatic diseases. Based on the scarce data available, this review focuses on capillaroscopic findings in healthy children and adolescents as well as in children with juvenile systemic sclerosis, juvenile dermatomyositis, juvenile idiopathic arthritis, and Raynaud's phenomenon. In addition, it outlines the potential benefits and limitations of nailfold capillaroscopy for routine care in paediatric rheumatology.

One type of law that has an effect on youth behavior is juvenile curfew laws. These laws restrict the times that youth may occupy public places or streets. We systematically reviewed studies evaluating the effectiveness of these laws to address the question: Can juvenile curfew laws be used to improve youth public health and juvenile justice outcomes? In 2013, we used a standardized set of keywords to search 24 databases for studies that evaluated effectiveness outcome measures of juvenile curfew laws. After applying the exclusion criteria and removing duplicate studies, 14 studies of juvenile curfews remained. Of the six studies examining the effectiveness of juvenile curfew laws on adverse youth health outcomes, five found a positive impact. Of the eight studies examining the effectiveness of curfew laws on juvenile crime and victimization, four found a positive impact. The studies that found that juvenile curfew laws were effective at reducing adverse youth health outcomes (e.g., trauma transports); juvenile crime; and victimization were of higher quality (e.g., stronger methodologic approaches) than those finding no effects. However, given the limited number of studies and concerns with quality, we conclude that more research is needed before conclusions can be drawn about the effectiveness of juvenile curfew laws.

1981-03-01

Twelve juvenile bonnet macaques (Macaca radiata), 6 males and 6 females, were presented with color videotape recordings of 3 types of social stimuli. The stimulus animals, all unfamiliar adult conspecifics, consisted of a passive female, a passive male, and a threatening male. Subjects were observed in the presence of their mother and 1 other juvenile-mother dyad. The juveniles showed the highest scores for contact with mother when presented with the threatening male stimulus. Similarly, subjects lipsmacked significantly more to the male threatening male stimulus than to either the passive male or female. The female stimulus was approached significantly more than either the passive or threatening male. Results suggest that juvenile macaques will respond to social stimuli presented through color video recordings in a socially appropriate manner. This technique provides a new tool in the investigation of social perception in nonhuman primates.

Juvenile scleroderma is a rarely seen chronic connective tissue disorder characterized by stiffening of the skin. The frequency of the disease was reported as one per million. According to organ involvement, the disease is divided into two main forms: systemic and localized scleroderma. Since it is uncommon in children, many aspects of the disease remain discussable. With this review, we aimed to revise recent findings and new developments in this rare condition. Skin manifestations are most prominent feature of the systemic form, followed by musculoskeletal and vascular involvement. Cardiovascular, gastrointestinal and renal disorders are rare in childhood. Combination of disease modifying antirheumatic drugs (methotrexate, mycophenolate-mofetil, cyclosporine) and steroid reprents the first line therapy. Bosentan is used for cases with pulmonary hypertension and for extensive digital ulcerations. Biological treatment emerges as a useful treatment option in most severe form of the disease. Localized scleroderma is characterized with sclerodermatosis of the skin. Internal organ involvement is not expected. Classification of the local scleroderma is made according to the size and localization of the skin changes. There are few different therapeutical options but there is no specific therapy for the localized scleroderma. Many data regarding disease features and treatment options in juvenile scleroderma are based on studies among adults. There is a striking need for multicentric, prospective studies among children with juvenile scleroderma.Emerging biological agents and new treatment options are showing promising results. Anyhow, juvenile scleroderma remains a mystery with many aspects of the disease waiting to be solved. Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.org.

An Enriched Environment Promotes Shelter-Seeking Behaviour and Survival of Hatchery-Produced Juvenile European Lobster (Homarus gammarus)

The high loss of newly released hatchery-reared European lobster (Homarus gammarus) juveniles for stock enhancement is believed to be the result of maladaptive anti-predator behaviour connected to deprived stimuli in the hatchery environment. Our objective was to learn if an enriched hatchery environment enhances shelter-seeking behaviour and survival. In the “naïve” treatment, the juveniles were raised in single compartments without substrate and shelter whereas juveniles in the “exposed” treatment experienced substrate, shelter and interactions with conspecifics. Three experiments with increasing complexity were conducted. Few differences in shelter-seeking behaviour were found between treatments when one naïve or one exposed juvenile were observed alone. When observing interactions between one naïve and one exposed juvenile competing for shelter, naïve juveniles more often initiated the first aggressive encounter. The third experiment was set up to simulate a release for stock enhancement. Naïve and exposed juveniles were introduced to a semi-natural environment including substrate, a limited number of shelters and interactions with conspecifics. Shelter occupancy was recorded three times during a period of 35 days. Exposed juveniles occupied more shelters, grew larger and had higher survival compared with naïve juveniles. Our results demonstrate that experience of environmental complexity and social interactions increase shelter-seeking ability and survival in hatchery reared lobster juveniles. PMID:27560932

Growing pressure to develop public lands for renewable energy production places several protected species at increased risk of habitat loss. One example is the Mojave desert tortoise (Gopherus agassizii), a species often at the center of conflicts over public land development. For this species and others on public lands, a better understanding of their habitat needs can help minimize negative impacts and facilitate protection or restoration of habitat. We used radio-telemetry to track 46 neonate and juvenile tortoises in the Eastern Mojave Desert, California, USA, to quantify habitat at tortoise locations and paired random points to assess habitat selection. Tortoise locations near burrows were more likely to be under canopy cover and had greater coverage of perennial plants (especially creosote [Larrea tridentata]), more coverage by washes, a greater number of small-mammal burrows, and fewer white bursage (Ambrosia dumosa) than random points. Active tortoise locations away from burrows were closer to washes and perennial plants than were random points. Our results can help planners locate juvenile tortoises and avoid impacts to habitat critical for this life stage. Additionally, our results provide targets for habitat protection and restoration and suggest that diverse and abundant small-mammal populations and the availability of creosote bush are vital for juvenile desert tortoises in the Eastern Mojave Desert.

Spatial refugia mediate juvenile coral survival during coral-predator interactions

Coral recruitment and juvenile growth are essential processes for coral population maintenance and recovery. A growing body of research has evaluated the influence of reef microstructure on coral settlement and post-settlement survival, showing that physical refugia enhance recruitment. These studies have evaluated coral recruit morality from competition with macroalgae and indirect predation by grazing organisms, but the impact of direct predation by corallivorous piscine species on juvenile corals and how this interacts with reef microstructure is relatively unknown. This study examined whether refugia provided by micro-crevices enhance juvenile coral survival from corallivory. Juvenile corals from two different functional groups, the slow-growing massive Porites lobata and fast-growing branching Pocillopora damicornis, with average nubbin sizes of 1.4 cm × 0.3 cm and 0.5 cm × 1.0 cm (diameter × height), respectively, were attached to experimental tiles using small (1.44 cm3) and large (8.0 cm3) crevice sizes and were monitored for 29 d on a forereef in Palau. Full crevices (four sided) enhanced coral survival compared to exposed microhabitats in both coral taxa, but crevice size did not alter survival rates. Corallivores targeted recruits within crevices regardless of crevice size; dominant predators included small triggerfish (Balistidae), butterflyfish ( Chaetodon), and wrasse ( Cheilinus). Overall, Pocillopora suffered much higher rates of mortality than Porites. All Pocillopora were consumed by day 8 of the experiment, but mortality was significantly delayed in full crevices compared to exposed and partial crevice (three sided) microhabitats. In contrast, Por. lobata located in all microhabitats survived the entire experiment up to 29 d, with high survival in full (>90%) and partial crevices (70%), but only 28% survival in exposed microhabitats. These findings show the importance of crevices as spatial refugia from predators for juvenile corals and

To quantitatively evaluate the change of the coxofemoral joints using computed tomography and distraction index in a cat with hip dysplasia treated by juvenile pubic symphysiodesis. Case report. Eighteen-week-old female entire Maine Coon cat. Juvenile pubic symphysiodesis resulted in changes in the distraction index, acetabular angle, dorsal acetabular rim angle, dorsal acetabular sector angle, and clinical improvement at the six month follow-up. No intra-operative or postoperative complications were recorded. Juvenile pubic symphysiodesis performed at 18 weeks of age resulted in improvement in hip joint conformation and hip laxity in a dysplastic cat. Juvenile pubic symphysiodesis may be a promising treatment for feline hip dysplasia and is a safe and technically simple procedure to perform. Further investigations are warranted.

Juvenile angiofibroma is an uncommon, benign, locally aggressive vascular tumor. It is found almost exclusively in young men. Common presenting symptoms include nasal obstruction and epistaxis. More advanced tumors may present with facial swelling and visual or neurological disturbances. The evaluation of patients with juvenile angiofibroma relies on diagnostic imaging. Preoperative biopsy is not recommended. The mainstay of treatment is resection combined with preoperative embolization. Endoscopic surgery is the approach of choice in early stages, whereas, in advanced stages, open or endoscopic approaches are feasible in expert hands. Postoperative radiotherapy (RT) or stereotactic radiosurgery seem valuable in long-term control of juvenile angiofibroma, particularly those that extend to anatomically critical areas unsuitable for complete resection. Chemotherapy and hormone therapy are ineffective. The purpose of the present review was to update current aspects of knowledge related to this rare and challenging disease. © 2017 Wiley Periodicals, Inc.

The propagation of hard-branch cuttings of tetraploid Robinia pseudoacacia (black locust) is restricted by the low rooting rate; however, etiolated juvenile tetraploid black locust branches result in a significantly higher rooting rate of cuttings compared with non-etiolated juvenile tetraploid branches. To identify proteins that influence the juvenile tetraploid branch rooting process, two-dimensional electrophoresis (2-DE) and matrix-assisted laser desorption/ionization time-of-flight/time-of-flight mass spectra (MALDI-TOF/TOF-MS) were used to analyze proteomic differences in the phloem of tetraploid R. pseudoacacia etiolated and non-etiolated juvenile branches during different cutting periods. A total of 58 protein spots differed in expression level, and 16 protein spots were only expressed in etiolated branches or non-etiolated ones. A total of 40 highly expressed protein spots were identified by mass spectrometry, 14 of which were accurately retrieved. They include nucleoglucoprotein metabolic proteins, signaling proteins, lignin synthesis proteins and phyllochlorin. These results help to reveal the mechanism of juvenile tetraploid R. pseudoacacia etiolated branch rooting and provide a valuable reference for the improvement of tetraploid R. pseudoacacia cutting techniques.

Weapons used by juveniles and adult offenders in U.S. parricide cases.

Heide, Kathleen M; Petee, Thomas A

2007-11-01

In recent decades, attention has focused on juveniles who kill their parents. Research has indicated that increases in juvenile homicide have been associated with the availability of firearms, but little is known about the weapons juveniles use to kill their parents and whether their weapon usage is different from that of adult children who kill their parents. This article uses Supplementary Homicide Report data for the 24-year period 1976 to 1999 to investigate weapons selected by parricide offenders to kill biological mothers and fathers. Significant differences were found in the weapons used in matricide and patricide incidents and in the weapons selected by juvenile and adult offenders. A comparison with an earlier study by Heide revealed that weapon usage in parricide events is stable. Differences found in both studies between weapons used to kill parents and offender age are consistent with a physical strength hypothesis proposed by Heide in 1993.

'Scared Straight' and other similar programs involve organized visits to prison by juvenile delinquents or children at risk for criminal behavior. Programs are designed to deter participants from future offending through first hand observation of prison life and interaction with adult inmates. These programs remain in use despite research questioning their effectiveness. This is an update of a 2002 review. To assess the effects of programs comprising organized visits to prisons by juvenile delinquents (officially adjudicated, that is, convicted by a juvenile court) or pre-delinquents (children in trouble but not officially adjudicated as delinquents), aimed at deterring them from delinquency. To update this review, we searched 22 electronic databases, including CENTRAL, MEDLINE, PsycINFO, and Criminal Justice Abstracts, in December 2011. In addition, we searched clinical trials registries, consulted experts, conducted Google Scholar searches,and followed up on all relevant citations. We included studies that tested programs involving the organized visits of delinquents or children at risk for delinquency to penal institutions such as prisons or re formatives. Studies that had overlapping samples of juvenile and young adults (for example, ages 14 to 20 years) were included. We only considered studies that assigned participants to conditions randomly or quasi-randomly (that is,by odd/even assignment to conditions). Each study had to have a no-treatment control condition and at least one outcome measure of 'post-visit' criminal behavior. The search methods for the original review generated 487 citations, most of which had abstracts. The lead review author screened these citations, determining that 30 were evaluation reports. Two review authors independently examined these citations and agreed that 11 were potential randomized trials. All reports were obtained. Upon inspection of the full-text reports, two review authors independently agreed to exclude two studies

Foraging Behaviour of Juvenile Female New Zealand Sea Lions (Phocarctos hookeri) in Contrasting Environments

Foragers can show adaptive responses to changes within their environment through morphological and behavioural plasticity. We investigated the plasticity in body size, at sea movements and diving behaviour of juvenile female New Zealand (NZ) sea lions (Phocarctos hookeri) in two contrasting environments. The NZ sea lion is one of the rarest pinnipeds in the world. Most of the species is based at the subantarctic Auckland Islands (AI; considered to be marginal foraging habitat), with a recolonizing population on the Otago Peninsula, NZ mainland (considered to be more optimal habitat). We investigated how juvenile NZ sea lions adjust their foraging behaviour in contrasting environments by deploying satellite-linked platform transmitting terminals (PTTs) and time-depth recorders (TDRs) on 2–3 year-old females at AI (2007–2010) and Otago (2009–2010). Juvenile female NZ sea lions exhibited plasticity in body size and behaviour. Otago juveniles were significantly heavier than AI juveniles. Linear mixed effects models showed that study site had the most important effect on foraging behaviour, while mass and age had little influence. AI juveniles spent more time at sea, foraged over larger areas, and dove deeper and longer than Otago juveniles. It is difficult to attribute a specific cause to the observed contrasts in foraging behaviour because these differences may be driven by disparities in habitat/prey characteristics, conspecific density levels or interseasonal variation. Nevertheless, the smaller size and increased foraging effort of AI juveniles, combined with the lower productivity in this region, support the hypothesis that AI are less optimal habitat than Otago. It is more difficult for juveniles to forage in suboptimal habitats given their restricted foraging ability and lower tolerance for food limitation compared to adults. Thus, effective management measures should consider the impacts of low resource environments, along with changes that can alter food

Juvenile Gaucher disease simulating osteomyelitis

A case in which several imaging procedures suggested juvenile Gaucher disease in a child who presented with symptomatology of osteomyelitis is discussed. The 20-month girl was given a Technetium-99m radionuclide skeletal examination which revealed intense uptake of tracer agents along the shaft of the right femur. It was also found that the liver and spleen were dramatically Ga-67 avid. The bone pain symptomatology suggested an osteomyelitis of the femur, but skeletal scintigraphy with Tc-99m-labeled bone tracer demonstrated photopenic areas involving the femur, suggesting that the bone pain may have been due to marrow packed with Gaucher cells. This overexpansion ofmore » the marrow may lead to microfractures with remodeling seen radiographically as periosteal new bone and scintigraphically as increased periosteal deposition of tracer agent. The radiogallium study was useful to exclude an underlying osteomyelitis in the involved femurs. Although juvenile Gaucher disease is unusual, it should be considered in any child who presents with the constellation of hepatosplenomegaly and bone pain simulating osteomyelitis.« less

Family transitions and juvenile delinquency.

Schroeder, Ryan D; Osgood, Aurea K; Oghia, Michael J

2010-01-01

There is a large body of research that shows children from non-intact homes show higher rates of juvenile delinquency than children from intact homes, partially due to weaker parental control and supervision in non-intact homes. What has not been adequately addressed in the research is the influence of changes in family structure among individual adolescents over time on delinquent offending. Using the first and third waves of the National Youth Study, we assess the effect of family structure changes on changes in delinquent offending between waves through the intermediate process of changes in family time and parental attachment. Although prior research has documented adolescents in broken homes are more delinquent than youth in intact homes, the process of family dissolution is not associated with concurrent increases in offending. In contrast, family formation through marriage or cohabitation is associated with simultaneous increases in offending. Changes in family time and parental attachment account for a portion of the family formation effect on delinquency, and prior parental attachment and juvenile offending significantly condition the effect of family formation on offending.

Who decides? The decision-making process of juvenile judges concerning minors with mental disorders.

PubMed

Cappon, Leen

2016-01-01

Previous research on juvenile judges' decision-making process has neglected the role of the different actors involved in judicial procedures. The decision can be considered as a result of information exchange between the different actors involved. The process of making a decision is equally important as the decision itself, especially when the decision considers minors with mental disorders. The presence and the type of interaction determine the information available to the juvenile judges to make their final decision. The overall aim of this study is to gain insight into the role of all actors, including the juvenile judge, in the juvenile judge's decision-making process in cases relating to minors with mental disorders. Semi-structured interviews were carried out with professional actors (n=32), minors (n=31) and parents (n=17). The findings indicated that the judge's decision is overall the result of an interaction between the juvenile judge, the social services investigator and the youth psychiatrist. The other professional actors, the minors and the parents had only a limited role in the decision-making process. The research concludes that the judge's decision-making process should be based on dialogue, and requires enhanced collaboration between the juvenile court and youth psychiatrists from mental health services. Future decision-making research should pay more attention to the interactions of the actors that guide a juvenile judge's decision. Copyright © 2016 Elsevier Ltd. All rights reserved.

Neurofibromatosis type 1 diagnosed in a child based on multiple juvenile xanthogranulomas and juvenile myelomonocytic leukemia.

2015-01-01

An association between juvenile xanthogranuloma (JXG), neurofibromatosis type 1 (NF1), and juvenile myelomonocytic leukemia (JMML) has been described in the literature but has only been documented in approximately 20 cases. We diagnosed a patient with NF1 at 25 months of age, before any cutaneous stigmata of this disease had appeared, because we decided to screen for the NF1 gene mutation because of his presentation with multiple JXGs and moderate macrocephaly (2.5 standard deviations) at 9 months of age and JMML diagnosed at 20 months of age. The child is well today after treatment with chemotherapy and allogenic bone marrow transplantation. With increased awareness, patients with JXG and NF1 who develop symptoms possibly related to JMML, such as paleness, skin bleeding, cough, unexplained fever, and hepatosplenomegaly, should be further evaluated. We also emphasize that multiple JXG lesions can be an early marker of NF1. © 2014 Wiley Periodicals, Inc.

Early-Life Stress Triggers Juvenile Zebra Finches to Switch Social Learning Strategies.

Farine, Damien R; Spencer, Karen A; Boogert, Neeltje J

2015-08-17

Stress during early life can cause disease and cognitive impairment in humans and non-humans alike. However, stress and other environmental factors can also program developmental pathways. We investigate whether differential exposure to developmental stress can drive divergent social learning strategies between siblings. In many species, juveniles acquire essential foraging skills by copying others: they can copy peers (horizontal social learning), learn from their parents (vertical social learning), or learn from other adults (oblique social learning). However, whether juveniles' learning strategies are condition dependent largely remains a mystery. We found that juvenile zebra finches living in flocks socially learned novel foraging skills exclusively from adults. By experimentally manipulating developmental stress, we further show that social learning targets are phenotypically plastic. While control juveniles learned foraging skills from their parents, their siblings, exposed as nestlings to experimentally elevated stress hormone levels, learned exclusively from unrelated adults. Thus, early-life conditions triggered individuals to switch strategies from vertical to oblique social learning. This switch could arise from stress-induced differences in developmental rate, cognitive and physical state, or the use of stress as an environmental cue. Acquisition of alternative social learning strategies may impact juveniles' fit to their environment and ultimately change their developmental trajectories. Copyright © 2015 The Authors.

In recent years, there has been an increasing interest in juvenile sex offenders showing that this population is highly heterogeneous. The aim of the present study was to identify possible different profiles that could help understand the motivation behind offending, comparing 31 Juvenile Sexual Offenders (JSOs), 31 Juvenile Sexual Non Offenders (JSNOs) and 31 Juvenile Non Offenders (Control Group). A data collection form, the Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A) or Minnesota Multiphasic Personality Inventory-2 (MMPI-2), the Coping Inventory for Stressful Situations (CISS) and the Parental Bonding Inventory (PBI) were administered to all participants. The results show that JSOs differs from JNSOs in some domains, such as living in single-parent homes, while maintain some common aspects such as academic failure and previous sexual intercourse. Moreover, JNSOs showed more abnormal personality traits, such as Authority Problems, MacAndrew Alcoholism, Acknowledgement and Alcohol-Drug Problem Proneness compared to JSOs and the Control Group, while JSOs and JNSOs use a coping strategy more oriented to Avoidance and Distraction compared to the Control group. Finally, JSOs described the relationships with fathers characterized by higher care and protection than JNSOs. These findings provide additional evidence with respect the prevention and treatment of criminal sexual behavior in adolescent. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

In order to understand the molecular mechanisms of longevity regulation, we recently performed a screen designed to enrich for genes common to several longevity interventions. Using this approach, we identified the Drosophila melanogaster gene takeout. takeout is upregulated in a variety of long-lived flies, and extends life span when overexpressed. Here, we investigate the mechanisms of takeout-dependent longevity. takeout overexpression specifically in the fat body is sufficient to increase fly longevity and is additive to the longevity effects of dietary restriction. takeout long-lived flies do not show phenotypes often associated with increased longevity, such as enhanced stress resistance or major metabolic abnormalities. However, males exhibit greatly diminished courtship behavior, leading to a reduction in fertility. Interestingly, takeout contains a binding domain for Juvenile Hormone, a fly hormone that plays a role in the regulation of developmental transitions. Importantly, the longevity and courtship phenotypes of takeout overexpressing flies are reversed by treatment with the Juvenile Hormone analog methoprene. These data suggest that takeout is a key player in the tradeoff-switch between fertility and longevity. takeout may control fertility via modulation of courtship behavior. This regulation may occur through Juvenile Hormone binding to takeout and a subsequent reduction in Juvenile Hormone signaling activity. PMID:22940452

The objective of our study was to correlate specimens of juvenile osteochondritis dissecans (OCD) lesions of the knee to MRI examinations to elucidate the histopathologic basis of characteristic imaging features. Five children (three boys and two girls; age range, 12-13 years old) who underwent transarticular biopsy of juvenile OCD lesions of the knee were retrospectively included in this study. Two radiologists reviewed the MRI examinations and a pathologist reviewed the histopathologic specimens and recorded characteristic features. Digital specimen photographs were calibrated to the size of the respective MR image with the use of a reference scale. Photographs were rendered semitransparent and over-laid onto the MR image with the location chosen on the basis of the site of the prior biopsy. A total of seven biopsy specimens were included. On MRI, all lesions showed cystlike foci in the subchondral bone, bone marrow edema pattern on proton density-or T2-weighted images, and relatively thick unossified epiphyseal cartilage. In four patients, a laminar signal intensity pattern was seen, and two patients had multiple breaks in the subchondral bone plate. Fibrovascular tissue was found at histopathology in all patients. Cleft spaces near the cartilage-bone interface and were seen in all patients while chondrocyte cloning was present in most cases. Focal bone necrosis and inflammation were infrequent MRI findings. Precise correlation of the MRI appearance to the histopathologic overlays consistently was found. A direct correlation exists between the histopathologic findings and the MRI features in patients with juvenile OCD. Additional studies are needed to correlate these MRI features with juvenile OCD healing success rates.

Psychogenic non-epileptic seizures (PNES) tend to begin in adolescence and young adulthood, although the seizures can occur in a wide range of ages. In the current study, we investigated the age of onset in patients with PNES and tried to determine the correlation between the age of onset and the demographic and clinical characteristics and factors potentially predisposing to PNES. In this cross-sectional study, all patients with a clinical diagnosis of PNES were recruited at the outpatient epilepsy clinic at Shiraz University of Medical Sciences from 2008 to 2012. We dichotomized the patients into two groups; those with age of onset below 18 years (juvenile), and those with age of onset at 18-55 years (adult-onset). We studied the demographic and clinical characteristics and factors potentially predisposing to PNES between these two groups. Statistical analyses were performed using Chi square and Fisher's Exact tests and Mann-Whitney U test. Fifty-seven patients with juvenile and 129 people with adult-onset PNES were studied. Demographic characteristics of these two groups were not different significantly. Seizure characteristics and semiology in these two groups were not significantly different either. However, factors potentially predisposing to PNES were significantly different between these two groups. History of being abused, academic failure, epilepsy or family history of epilepsy were more frequently observed in juvenile PNES, while medical comorbidities were more frequent among patients with adult-onset PNES. Age of onset of PNES is not correlated with the clinical manifestations; however, factors potentially predisposing to PNES are significantly different in patients with juvenile compared to those with adult-onset PNES.

Animals display a repertoire of different social behaviours. Appropriate behavioural responses depend on sensory input received during social interactions. In mice, social behaviour is driven by pheromones, chemical signals that encode information related to age, sex and physiological state. However, although mice show different social behaviours towards adults, juveniles and neonates, sensory cues that enable specific recognition of juvenile mice are unknown. Here we describe a juvenile pheromone produced by young mice before puberty, termed exocrine-gland secreting peptide 22 (ESP22). ESP22 is secreted from the lacrimal gland and released into tears of 2- to 3-week-old mice. Upon detection, ESP22 activates high-affinity sensory neurons in the vomeronasal organ, and downstream limbic neurons in the medial amygdala. Recombinant ESP22, painted on mice, exerts a powerful inhibitory effect on adult male mating behaviour, which is abolished in knockout mice lacking TRPC2, a key signalling component of the vomeronasal organ. Furthermore, knockout of TRPC2 or loss of ESP22 production results in increased sexual behaviour of adult males towards juveniles, and sexual responses towards ESP22-deficient juveniles are suppressed by ESP22 painting. Thus, we describe a pheromone of sexually immature mice that controls an innate social behaviour, a response pathway through the accessory olfactory system and a new role for vomeronasal organ signalling in inhibiting sexual behaviour towards young. These findings provide a molecular framework for understanding how a sensory system can regulate behaviour.

Previous studies of symbiotic associations between scleractinians corals and Symbiodinium have demonstrated that the consortium of symbionts can change in response to environmental conditions. However, less is known about symbiont shuffling during early coral development, particularly in brooding species. This study examined whether Symbiodinium consortia (1) varied in Porites astreoides on shallow (10m) and upper mesophotic (30m) reefs, (2) changed during coral development, and (3) influenced growth of juveniles in different environments. Symbiodinium ITS2 sequences were amplified using universal primers and analyzed using phylotype-specific primers designed for phylotypes A, B, and C. Adults from both depths were found to host only phylotype A, phylotypes A and B, or phylotypes A, B, and C and the frequency of the phylotype composition did not vary with depth. However, phylotype A was the dominant symbiont that was vertically transmitted to the planulae. The presence of phylotypes B and C was detected in the majority of juveniles when transplanted onto the shallow and upper mesophotic reefs whereas only phylotype A was detected in the majority of juveniles reared in outdoor aquaria. In addition, growth of juvenile P. astreoides harboring different combinations of Symbiodinium phylotypes did not vary when transplanted to different reef zones. However, juveniles reared in in situ reef environments grew faster than those reared in ex situ outdoor aquaria. These results show that Symbiodinium consortia change during development of P. astreoides and are influenced by environmental conditions. PMID:28182684

Juvenile white sturgeon, Acipenser transmontanus, have not been commonly identified as prey items in digestive tracts of fishes collected in the wild. In particular, the diet of northern pikeminnow, Ptychocheilus oregonensis, an abundant Pacific Northwest freshwater predator which has been widely studied, has not included juvenile white sturgeon. To aid in interpreting these results and help in planning future feeding studies, we determined the persistence of identifiable remains of white sturgeon juveniles in this predator's digestive tract. Northern pikeminnow (mean total length = 476 mm), were force-fed meals of 2 or 3 juvenile white sturgeon (mean total length = 91 mm). After digestive periods of 4, 8, 16, 24, 28, and 32h at a water temperature of about 17 ??C, fish were sacrificed, digestive tracts removed, and contents examined. Our results indicate that juvenile white sturgeon would be readily discernable in digestive tracts of northern pikeminnow at least a day after feeding, with scutes remaining undigested and identifiable for 28 h.

While researchers have found that African American youth experience higher levels of juvenile justice involvement at every system level (arrest, sentencing, and incarceration) relative to their other ethnic counterparts, few studies have explored how juvenile justice involvement and number of contacts might be correlated with this broad range of problems. A convenience sample of 638 African American adolescents living in predominantly low-income, urban communities participated in a survey related to juvenile justice involvement. Major findings using logistic regression models indicated that adolescents who reported juvenile justice system involvement versus no involvement were 2.3 times as likely to report mental health problems, substance abuse, and delinquent or youth offending behaviors. Additional findings documented that the higher the number of juvenile justice system contacts, the higher the rates of delinquent behaviors, alcohol and marijuana use, sex while high on drugs, and commercial sex. These findings suggest that identifying and targeting youth who have multiple juvenile justice system contacts, especially those in low-resourced communities for early intervention services, may be beneficial. Future research should examine whether peer network norms might mediate the relationships between juvenile justice involvement and youth problem behaviors. PMID:28966415

Coxsackievirus B (CVB) is an enterovirus that most commonly causes a self-limited febrile illness in infants, but cases of severe infection can manifest in acute myocarditis. Chronic consequences of mild CVB infection are unknown, though there is an epidemiologic association between early subclinical infections and late heart failure, raising the possibility of subtle damage leading to late-onset dysfunction, or chronic ongoing injury due to inflammatory reactions during latent infection. Here we describe a mouse model of juvenile infection with a subclinical dose of coxsackievirus B3 (CVB3) which showed no evident symptoms, either immediately following infection or in adult mice. However following physiological or pharmacologically-induced cardiac stress, juvenile-infected adult mice underwent cardiac hypertrophy and dilation indicative of progression to heart failure. Evaluation of the vasculature in the hearts of adult mice subjected to cardiac stress showed a compensatory increase in CD31+ blood vessel formation, although this effect was suppressed in juvenile-infected mice. Moreover, CVB3 efficiently infected juvenile c-kit+ cells, and cardiac progenitor cell numbers were reduced in the hearts of juvenile-infected adult mice. These results suggest that the exhausted cardiac progenitor cell pool following juvenile CVB3 infection may impair the heart's ability to increase capillary density to adapt to increased load.

High morbidity of mental disorders among juvenile offenders has been confirmed by several studies, thus challenging both the juvenile justice system and the mental health system. Data from developed countries may not reflect the situation in low-income countries and therefore cannot form a basis for intervention. No similar study has been done in Sudan. The objective to determine prevalence of psychiatric disorders among incarcerated youth in Al-Juref juvenile correctional facility. All juveniles (forty eight) were studied utilizing a descriptive cross-sectional study design. Data was collected using a socio-demographic questionnaire and the MINI-KID 6.0 and was analyzed using the SPSS v.20. Most respondents were males (Forty six) with a mean age of fifteen (±1.6 years SD). Most were living with both parents (75%) and were school dropouts (41.7%). The majority was arrested for theft (33.3%) and rape (29.2%). Prevalence of psychiatric disorders was high (60.4%) with conduct disorder (CD) being the most common (47.9%), followed by anxiety disorders (31.1%) and major depressive disorder (14.6%). Comorbid psychiatric disorders rate was high (31%). Even after subtracting CD, prevalence was still common (39%). New information can help mental health providers and policy makers in the juvenile justice system make effective interventions in provision of mental health services. We recommend clinical assessment for juveniles when they appear at court and training of workers in the justice system on how to detect features of psychopathology. PMID:28096556
