    Acid-fast intranuclear inclusion bodies were found in the cells of the proximal convoluted tubules of the kidneys of mallards fed one, two, three or eight number 6 lead shot and maintained on cracked or whole corn and on grain-duck pellet diets. No acid-fast inclusion bodies were found in mallards fed one or three lead shot but maintained on a duck pellet ration. Dietary factors may be responsible for the failure of mallards fed a duck pellet ration to develop lead Inclusion bodies when treated with one or three lead shot. The authors suggest these inclusion bodies can be used as presumptive evidence for lead intoxication in mallards.

  2. Ultrastructural cytochemical analysis of intranuclear arsenic inclusions

    To establish the chemical composition of the arsenic inclusion, freshly isolated preparations of inclusions and epon-embedded thin sections of inclusions were subjected to ultrastructural cytochemical analysis. Intranuclear inclusions are composed of amorphous, arsenic-containing subunits aligned linearly to form a coiled complex. Lipase, ribonuclease, deoxyribonuclease, trypsin, pepsin, protease, amylase, or ethylenediaminetetraacetic acid (EDTA) was used to digest or chelate these inclusions. Following enzymatic digestion or chelation, the electron opacity of inclusions was compared with that of control sections exposed for equal times to equivalent solutions lacking the enzymes. Exposure to amylase caused a consistent reduction in the electron opacity of thin sections of inclusions and almost complete digestion of the freshly isolated preparations of inclusions. This was indicative of the presence of a carbohydrate moiety within arsenic inclusions. Incubation of inclusions with EDTA resulted in solubilization of freshly isolated and thin-sectioned embedded material. These data indicated that the intranuclear arsenic inclusion is composed of both metallic and carbohydrate moieties, confirming earlier studies which identified arsenic within inclusions using instrumental neutron activation analysis and x-ray microprobe analysis.

    Schwann cells in ciliary ganglia of fowls aged five to seven years were found to contain numerous intranuclear inclusions and pseudo-inclusions. Similar inclusions were usually absent from both neurons and non-neuronal cells, including connective tissue cells, and were rare in Schwann cells of chickens aged less than five years. Inclusions were of two different types: filamentous bundles and granulofibrillar bodies. Individual nuclei contained one to three inclusions. Pseudo-inclusions, i.e. cytoplasmic pockets invaginated into the nuclei, were found more rarely and accompanied one or both types of 'true' inclusions. The possible significance of these findings in relation to ageing phenomena is discussed. It is concluded that intranuclear inclusions appear to be a consequence of nuclear/cellular activation and may be regarded as aggregates of previously dispersed intranuclear proteins.

    Neuronal intranuclear inclusion disease (NIID) is a slowly progressive neurodegenerative disease characterized by eosinophilic hyaline intranuclear inclusions in the central and peripheral nervous system, and also in the visceral organs. NIID has been considered to be a heterogeneous disease because of the highly variable clinical manifestations, and ante-mortem diagnosis has been difficult. However, since we reported the usefulness of skin biopsy for the diagnosis of NIID, the number of NIID diagnoses has increased, in particular adult-onset NIID. In this study, we studied 57 cases of adult-onset NIID and described their clinical and pathological features. We analysed both NIID cases diagnosed by post-mortem dissection and by ante-mortem skin biopsy based on the presence of characteristic eosinophilic, hyaline and ubiquitin-positive intanuclear inclusion: 38 sporadic cases and 19 familial cases, from six families. In the sporadic NIID cases with onset age from 51 to 76, dementia was the most prominent initial symptom (94.7%) as designated ‘dementia dominant group’, followed by miosis, ataxia and unconsciousness. Muscle weakness and sensory disturbance were also observed. It was observed that, in familial NIID cases with onset age less than 40 years, muscle weakness was seen most frequently (100%), as designated ‘limb weakness group’, followed by sensory disturbance, miosis, bladder dysfunction, and dementia. In familial cases with more than 40 years of onset age, dementia was most prominent (100%). Elevated cerebrospinal fluid protein and abnormal nerve conduction were frequently observed in both sporadic and familial NIID cases. Head magnetic resonance imaging showed high intensity signal in corticomedullary junction in diffusion-weighted image in both sporadic and familial NIID cases, a strong clue to the diagnosis. All of the dementia dominant cases presented with this type of leukoencephalopathy on head magnetic resonance imaging. Both sporadic and

    Ubiquitin-immunoreactive (ub-ir) neuronal cytoplasmic inclusions are characteristically found in the extramotor cortex in patients with motor neuron disease (MND) and dementia (MND-dementia) and in a subset of patients with frontotemporal dementia (FTD) without motor symptoms (FTD-MND type). Recently, ub-ir neuronal intranuclear inclusions have been described in a small number of patients with familial FTD-MND type. To better define the sensitivity and specificity of this pathological change, we examined postmortem tissue from 14 patients with FTD-MND type (8 familial, 6 sporadic), 10 cases of MND-dementia (5 familial, 5 sporadic) and 19 cases of MND with no history of cognitive dysfunction (2 familial, 17 sporadic). Numerous intranuclear inclusions were found in multiple anatomic sites in 6/8 cases of familial FTD-MND. Rare intranuclear inclusions were present in the hippocampal dentate granule cells in 1 case of familial MND-dementia. No sporadic cases had intranuclear inclusions. These findings suggest that intranuclear inclusions are specific for familial FTD and may identify a subset of families with a common genetic basis. Although intranuclear inclusions are most characteristic of families with pure FTD, they may also be found in some pedigrees with both FTD and MND, further supporting the hypothesis that FTD-MND type and MND-dementia represent a clinicopathological spectrum of disease.

    We report an incipient case of intranuclear inclusion body disease (INIBD) in a 78-year-old woman. No apparent neurological symptoms were noticed during the clinical course. Post mortem examination revealed widespread occurrence of eosinophilic intranuclear inclusions in neuronal and glial cells of the central and peripheral nervous systems, as well as in parenchymal cells of the visceral organs. The inclusions were observed more frequently in glial cells than in neuronal cells. Ultrastructurally, the inclusions consisted of granular and filamentous material. Immunohistochemically, the inclusions were positive for ubiquitin, ubiquitin-related proteins (NEDD8 ultimate buster 1, small ubiquitin modifier-1, small ubiquitin modifier-2 and p62), promyelocytic leukemia protein and abnormally expanded polyglutamine. Consistent with previous studies, the vast majority of inclusion-bearing glial cells were astrocytes. Furthermore, p25α-positive oligodendrocytes rarely contained intranuclear inclusions. These findings suggest that INIBD may occur in non-demented elderly individuals and that oligodendrocyte is also involved in the disease process of INIBD.

    We report a very unusual cytologic feature, intranuclear inclusion bodies, in mesothelioma of a predominantly adenomatoid type. The patient, a 57-year-old woman, was presented with dyspnea and right pleural effusion. Pleural aspiration cytology revealed many cohesive ball-like clusters, with a tubular pattern, composed of small atypical cells displaying a high-nuclear-cytoplasmic ratio. They had a nuclear groove and irregular intranuclear inclusion bodies. Right lung partial resection with thoracoscopy revealed that a white tumor had proliferated along the pleural surface at S(8) . Histology revealed nodular tumor cells forming dilated structures mixed with small tubular or glandular structures similar to those seen in benign adenomatoid tumors. These tumor cells had invaded peripheral lung tissues. Such inclusion bodies have not been reported earlier in mesothelioma. On the basis of this observation, we propose that the adenomatoid type of malignant mesothelioma be added to the differential diagnosis of malignant effusions when tumor cells with nuclear grooves and intranuclear inclusions are found in pleural aspiration cytology.

    Fragile X-associated tremor/ataxia syndrome (FXTAS) is a progressive neurodegenerative disorder that affects carriers of a FMR1 premutation. Symptoms include cerebellar ataxia, tremor, and cognitive deficits. The most characteristic pathology of FXTAS is the presence of eosinophilic ubiquitin-positive intranuclear inclusions in neurons and astrocytes throughout the nervous system and non-nervous tissues. Inclusions are present in neurons throughout the brain but are widely believed not to be present in the Purkinje cells (PCs) of the cerebellum. However, we analyzed 26 postmortem cases of FXTAS and demonstrated that 65 % of cases presented with inclusions within PCs of the cerebellum. We determined that the presence or absence of inclusions in PCs is correlated with age and that those cases with PC inclusions were overall 11 years older than those with no PC inclusions. Half of the cases with PCs with inclusions presented with twin nuclear inclusions. This novel finding demonstrating the presence of inclusions within PCs provides an insight into the understanding of the FXTAS motor symptoms and provides a novel target for the development of therapeutic strategies.

    Abnormal neuronal cytoplasmic inclusions (NCIs) containing aggregates of alpha-internexin and the neurofilament (NF) subunits, NF-H, NF-M, and NF-L, are the signature lesions of neuronal intermediate filament (IF) inclusion disease (NIFID). The disease has a clinically heterogeneous phenotype, including frontotemporal dementia, pyramidal and extrapyramidal signs presenting at a young age. NCIs are variably ubiquitinated and about half of cases also have neuronal intranuclear inclusions (NIIs), which are also ubiquitinated. NIIs have been described in polyglutamine-repeat expansion diseases, where they are strongly ubiquitin immunoreactive. The fine structure of NIIs of NIFID has not previously been described. Therefore, to determine the ultrastructure of NIIs, immunoelectron microscopy was undertaken on NIFID cases and normal aged control brains. Our results indicate that the NIIs of NIFID are strongly ubiquitin immunoreactive. However, unlike NCIs which contain ubiquitin, alpha-internexin and NF epitopes, NIIs contain neither epitopes of alpha-internexin nor NF subunits. Neither NIIs nor NCIs were recognised by antibodies to expanded polyglutamine repeats. The NII of NIFID lacks a limiting membrane and contains straight filaments of 20 nm mean width (range 11-35 nm), while NCIs contain filaments with a mean width of 10 nm (range 5-18 nm; t-test, P<0.001). Biochemistry revealed no differences in neuronal IF protein mobilities between NIFID and normal brain tissue. Therefore, NIIs of NIFID contain filaments morphologically and immunologically distinct from those of NCIs, and both types of inclusion lack expanded polyglutamine tracts of the triplet-repeat expansion diseases. These observations indicate that abnormal protein aggregation follows separate pathways in different neuronal compartments of NIFID.

    Cytologic findings of pulmonary carcinoid have been well described. We report new cytological findings in a case of carcinoid tumor. The patient is a 36-year-old man presenting with hemoptysis of about six months in duration. Chest CT scans showed a well-defined round polypoid lesion measuring 1 × 1 cm within the right upper lobe of the bronchus with hyperinflation of the right upper lobe. Trans-bronchial fine needle aspiration and biopsy were done. Cytologic smears showed isolated and loose clusters of uniform round to spindle shape cells with round centrally located nuclei, fine granular (salt and pepper) chromatin and pale cytoplasm. Intranuclear pseudo-inclusions and grooves were seen in some tumor cells. No mitotic figures or necrosis were evident. A cytological diagnosis of carcinoid tumor was made and histopathologic examination and subsequent immunohistochemical study confirmed the diagnosis. Carcinoid tumor may be reliably diagnosed on fine needle aspiration cytology smears. Intranuclear pseudo-inclusions and grooves may be evident in tumor cells.

    Valosin-containing protein (VCP) is associated with multiple cellular functions, including ubiquitin-dependent protein degradation. Mutations in VCP are known to cause inclusion body myopathy with Paget's disease and frontotemporal dementia and familial amyotrophic lateral sclerosis (fALS; ALS14), both of which are characterized by trans-activation response DNA protein 43 (TDP-43)-positive neuronal cytoplasmic and nuclear inclusions. Recently, immunoreactivity for fALS-associated proteins (TDP-43, fused in sarcoma (FUS), optineurin and ubiquilin-2) were reported to be present in cytoplasmic and nuclear inclusions in various neurodegenerative diseases. However, the extent and frequency of VCP-immunoreactive structures in these neurodegenerative diseases are uncertain. We immunohistochemically examined the brains of 72 cases with neurodegenerative diseases and five control cases. VCP immunoreactivity was present in Lewy bodies in Parkinson's disease and dementia with Lewy bodies, and neuronal nuclear inclusions in five polyglutamine diseases and intranuclear inclusion body disease, as well as in Marinesco bodies in aged control subjects. However, other neuronal and glial cytoplasmic inclusions in tauopathies and TDP-43 proteinopathies were unstained. These findings suggest that VCP may have common mechanisms in the formation or degradation of cytoplasmic and nuclear inclusions of neurons, but not of glial cells, in several neurodegenerative conditions.

    Unverricht-Lundborg disease (EPM1A), also known as Baltic myoclonus, is the most common form of progressive myoclonic epilepsy. It is inherited as an autosomal recessive trait, due to mutations in the Cystatin-B gene promoter region. Although there is much work on rodent models of this disease, there is very little published neuropathology in patients with EPM1A. Here, we present the neuropathology of a patient with genetically confirmed EPM1A, who died at the age of 76. There was atrophy and gliosis affecting predominantly the cerebellum, frontotemporal cortex, hippocampus and thalamus. We have identified neuronal cytoplasmic inclusions containing the lysosomal proteins, Cathepsin-B and CD68. These inclusions also showed immunopositivity to both TDP-43 and FUS, in some cases associated with an absence of normal neuronal nuclear TDP-43 staining. There were also occasional ubiquitinylated neuronal intranuclear inclusions, some of which were FUS immunopositive. This finding is consistent with neurodegeneration in EPM1A as at least a partial consequence of lysosomal damage to neurons, which have reduced Cystatin-B-related neuroprotection. It also reveals a genetically defined neurodegenerative disease with both FUS and TDP-43 related pathology.

    Cytologic diagnosis of adenomyoepithelioma can be very challenging. We report fine needle aspiration cytology (FNAC) findings of a benign adenomyoepithelioma. The cytologic features are characterized by hypercellularity and the presence of numerous atypical dispersed cells with epithelioid morphology and intact cytoplasm. The nuclei showed stippled chromatin, irregular nuclear membrane, and prominent eosinophilic nucleoli. No necrosis or mitoses were seen. The presence of naked nuclei, and extensive intranuclear cytoplasmic inclusions were identified and raised the possibility of adenomyoepithelioma. Immunohistochemically, the atypical cells showed strong positivity for myosin heavy chain, p63, and CK5/6, while the epithelial cells reacted with estrogen receptors. This immunophenotypic pattern supports the myoepithelial origin of the atypical cell proliferation and favors the diagnosis of benign adenomyoepithelioma. However, biopsy was recommended to exclude malignancy. Histologically, the tumor showed prominent myoepithelial cells with significant atypia, intranuclear cytoplasmic inclusions, and dense cytoplasm. No evidence of malignancy was identified. In conclusion, we report a case of adenomyoepithelioma with a significant cytological atypia that may result in confusion with malignant breast tumors. The presence of intranuclear cytoplasmic inclusions, naked nuclei, and expression of myoepithelial markers should provide clues to the right diagnosis and benign nature of this lesion. Cytopathologists should be familiarized with this entity to avoid a misdiagnosis of carcinoma.

    Globular inclusions are present in the nuclei of the columnar epithelial cells lining the ductus epididymidis in the garden dormouse, Eliomys quercinus L. Such inclusions have been reported in the dog where they are very abundant, in the stallion and in man. They have been found to be absent from sheep, cat, rabbit, guinea pig, rat and mouse. We have now found them in the garden dormouse, an ascrotal hibernator, but have been unable to detect them in another hibernator, the thirteen-lined ground squirrel Citellus tridecemlineatus, this time a scrotal mammal. The globular inclusions are first seen in the perinuclear space formed by the two membranes of the nuclear envelope; they are then invested by the inner membrane of the nuclear envelope and transferred into the nucleus. They later disintegrate and the vacuole is finally left with an electron-transparent content. The number of inclusions varies with the hormonal status of the animal: the granules are always present as soon as there is a rise in plasma testosterone. Electron energy-loss spectroscopy in the electron microscope (EELS) shows that inclusions contain C, N, O, Fe, Mg, P and S. This suggests that the intranuclear granules are made of protein cross-linked by disulphur bonds and contain iron, magnesium and phosphorus.

    There are very few conditions that present with dopa-responsive juvenile parkinsonism. We present two such children with neuronal intranuclear inclusion disease (NIID) who had an initial good levodopa response that was soon complicated by disabling dopa-induced dyskinesia. One child was diagnosed by rectal biopsy in life, and the other diagnosis was confirmed at postmortem. In this patient, dopamine transporter imaging showed severely decreased binding of the radiotracer in the striatum on both sides. Bilateral subthalamic deep brain stimulation in this patient produced initial improvement, but this was not sustained. Both patients died within 10 years of symptom onset. As well as levodopa responsiveness with rapid onset of dyskinesia, clues to the diagnosis of NIID in patients presenting with parkinsonism include the presence of gaze-evoked nystagmus, early onset dysarthria and dysphagia and oculogyric crises. Differential diagnosis of clinical symptoms and neuropathological findings are discussed including the approach to rectal biopsy for early diagnosis.

    Intranuclear and cytoplasmic inclusions in the renal proximal tubular epithelium were observed in nontreated male and female Wistar Hannover rats in a 26-week study (32 weeks of age) and a 104-week study (110 weeks of age). The incidence rates were less than 5% in these two studies. In affected animals, the inclusions were observed in more than 60% of proximal tubular epithelium as various sized (approximately 1-8 μm in diameter) round and eosinophilic materials, but not in distal tubules, Henle's loop, or collecting ducts. Ultrastructurally, inclusions appeared finely granular, homogenous with middle-electron density, and without a limiting membrane. These inclusions were determined to be protein histochemically stained by Azan-Mallory and immunoreactive with an antibody against D-amino acid oxidase (DAO). There was no abnormality in in-life observations or in clinical test values suggestive of renal dysfunction. There were no associated degenerative or inflammatory changes in the kidneys, and no similar inclusions were observed in the other organs. These inclusions are very similar to propiverine hydrochloride (propiverine) and norepinephreine/serotonin reuptake inhibitor-induced inclusions. This is the first report of accumulation of DAO and formation of inclusions occurring spontaneously in rat kidneys. The data are important for toxicological studies using Wistar Hannover rats.

    Huntington disease (HD) is a fatal neurodegenerative disease with no effective treatment. In the R6/1 mouse model of HD, environmental enrichment delays the neurologic phenotype onset and prevents cerebral volume loss by unknown molecular mechanisms. We examined the effects of environmental enrichment on well-characterized neuropathological parameters in a mouse model of HD. We found a trend toward preservation of downregulated neurotransmitter receptors in striatum of environmentally enriched mice and assessed possible enrichment-related modifications in gene expression using microarrays. We observed similar gene expression changes in R6/1 and R6/2 transgenic mice but found no specific changes in enrichment-related microarray expression profiles in either transgenic or wild-type mice. Furthermore, specific corrections in transprotein-induced transcriptional dysregulation in R6/1 mice were not detected by microarray profiling. However, gene-specific analyses suggested that long-term environmental enrichment may beneficially modulate gene expression dysregulation. Finally, environmental enrichment significantly decreased neuronal intranuclear inclusion load, despite unaffected transgene expression levels. Thus, the therapeutic effects of environmental enrichment likely contribute to decreasing aggregated polyglutamine protein levels without exerting strong effects on gene expression.

    The sigma-1 receptor (SIGMAR1) is one of the endoplasmic reticulum (ER) chaperones, which participate in the degradation of misfolded proteins via the ER-related degradation machinery linked to the ubiquitin-proteasome pathway. ER dysfunction in the formation of inclusion bodies in various neurodegenerative diseases has also become evident. Recently, we demonstrated that accumulation of SIGMAR1 was common to neuronal nuclear inclusions in polyglutamine diseases including Huntington's disease. Our study also indicated that SIGMAR1 might shuttle between the cytoplasm and the nucleus. In the present study, we investigated the role of SIGMAR1 in nuclear inclusion (NI) formation, using HeLa cells transfected with N-terminal mutant huntingtin. Cell harboring the mutant huntingtin produced SIGMAR1-positive NIs. SIGMAR1 siRNA and a specific inhibitor of the proteasome (epoxomicin) caused significant accumulation of aggregates in the cytoplasm and nucleus. A specific inhibitor of exportin 1 (leptomycin B) also caused NIs. Huntingtin became insolubilized in Western blot analysis after treatments with SIGMAR1 siRNA and epoxomicin. Furthermore, proteasome activity increased chronologically along with the accumulation of mutant huntingtin, but was significantly reduced in cells transfected with SIGMAR1 siRNA. By contrast, overexpression of SIGMAR1 reduced the accumulation of NIs containing mutant huntingtin. Although the LC3-I level was decreased in cells treated with both SIGMAR1 siRNA and control siRNA, the levels of LC3-II and p62 were unchanged. SIGMAR1 agonist and antagonist had no effect on cellular viability and proteasome activity. These findings suggest that the ubiquitin-proteasome pathway is implicated in NI formation, and that SIGMAR1 degrades aberrant proteins in the nucleus via the ER-related degradation machinery. SIGMAR1 might be a promising candidate for therapy of Huntington's disease.

    Acid-fastness is an uncommon characteristic shared by the genera Mycobacterium (Section 10A) and Nocardia. Because of this feature, this stain is extremely helpful in identification of these bacteria. Although Gram positive, acid-fast bacteria do not take the crystal violet into the wall well, appearing very light purple rather than the deep purple of normal Gram-positive bacteria.

    Intranuclear rods myopathy (IRM), a variant of nemaline myopathy (NM), is characterized by rod structure in the myonuclei. Patients with IRM present with similar symptoms to those of severe infantile-type NM but have worse outcome. Several extramuscular manifestations have been reported in NM but no dysautonomia. We herein report a 2-year-old girl with IRM and a heterozygous mutation, c.430C>T (p.L144F) in ACTA1. During the infancy, the patient showed severe diaphoresis and facial flushing. Arrhythmia and hypertension with the precipitating factors of feeding, defecation, and urination were observed. Sympathetic antagonist was prescribed and showed some effectiveness. Our report may widen the clinical spectrum of IRM. It also reminds clinicians that autonomic dysfunction may occur in patients with IRM or other actinopathies and appropriate treatment may be necessary.

    Introduction: Anaerobic acid fast bacilli (AFB) have not been previously reported in clinical microbiology. This is the second case report of a novel anaerobic AFB causing disease in humans. Case presentation: An anaerobic AFB was isolated from an abdominal wall abscess in a 64–year-old Caucasian diabetic male, who underwent distal pancreatectomy and splenectomy for resection of a pancreatic neuroendocrine tumour. The isolated bacteria were gram-variable and acid-fast, consisting of small irregular rods. The 16S rRNA gene sequence analysis showed that the isolate is a novel organism described in the literature only once before. The organism was studied at the CDC (Centers for Disease Control and Prevention) by the same group that worked with the isolates from the previous report; their findings suggest that the strain belongs to the suborder Corynebacterineae. Conclusion: This is the fifth reported case of an anaerobic AFB involved in clinical disease; its microbiological features and 16S RNA sequence are identical to previously reported cases. Clinical disease with this organism seems to be associated with recent history of surgery and abscess formation in deep soft tissues. Acquisition from surgical material is uncertain but seems unlikely. PMID:28348766

To assess their contributions to the spatial organization of the interphase genome, their interactions with the nucleoskeleton were examined in quiescent and activated human lymphocytes. The nucleoskeletons were prepared using “physiological” conditions. The resulting structures were probed for specific DNA sequences of centromeres, telomeres, and ribosomal genes by in situ hybridization; the electroeluted DNA fractions were examined by blot hybridization. In both nonstimulated and stimulated lymphocytes, centromeric alpha-satellite repeats were almost exclusively found in the eluted fraction, while telomeric sequences remained attached to the nucleoskeleton. Ribosomal genes showed a transcription-dependent attachment pattern: in unstimulated lymphocytes, transcriptionally inactive ribosomal genes located outside the nucleolus were eluted completely. When comparing transcription unit and intergenic spacer, significantly more of the intergenic spacer was removed. In activated lymphocytes, considerable but similar amounts of both rDNA fragments were eluted. The results demonstrate that: (a) the various repetitive DNA sequences differ significantly in their intranuclear anchoring, (b) telomeric rather than centromeric DNA sequences form stable attachments to the nucleoskeleton, and (c) different attachment mechanisms might be responsible for the interaction of ribosomal genes with the nucleoskeleton.

    Two methods, electron microscopy and wavelength dispersive electron probe microanalysis, were used to determine the intracellular sites and chemical form of concentrations of neptunium nitrate 237 after chronic intoxication by the intraperitoneal route in two organs in the rat known to concentrate this element (kidney, liver). Abnormal intranuclear formations in the form of clusters of dense granules containing neptunium, phosphorus, sulphur, and calcium were found in the nuclei of kidney proximal tubule cells and hepatocytes. These formations had a maximum diameter of the order of 2 microns and were located in the central part of the nucleus, away from the nucleolus and peripheral chromatin. Serious nuclear and cytoplasmic ultrastructural lesions are often associated in cells containing neptunium inclusions. The absorbed doses in the kidney and the liver were very low. A relationship between these abnormal intranuclear structures and the carcinogenic effect of neptunium remains to be clarified. This effect is related more probably to the chemical toxicity of Np 237.

    Inclusion body disease of suspected adenovirus etiology was the apparent cause of death of 9 captive kestrels (Falco sparverius). Cloacal hemorrhage was the only prominent gross lesion; disseminated hepatocellular necrosis and intranuclear inclusion bodies were evident microscopically. Attempts to reproduce the disease, and to propagate and serologically characterize the agent were unsuccessful.

    It is well known that intranuclear-cascade models generally overestimate the cross sections for one-proton removal from heavy, stable nuclei by a high-energy proton beam, but they yield reasonable predictions for one-neutron removal from the same nuclei and for one- nucleon removal from light targets. We use simple shell-model calculations to investigate the reasons of this deficiency. We find that a correct description of the neutron skin and of the energy density in the nuclear surface is crucial for the aforementioned observables. Neither ingredient is sufficient if taken separately.

    Nucleospora salmonis is an intra-nuclear microsporidian parasite in the family Enterocytozoonidae (Docker et al. 1997). Prespore stages of the parasite were first observed among adult and then juvenile Chinook salmon (Oncorhynchus tshawytscha) by Elston et al. (1987) and Morrison et al. (1990), respectively in Washington, U.S.A. The microsporidian nature of the parasite was subsequently confirmed by the observation of spores in lymphoblasts of juvenile Chinook salmon from California (Hedrick et al. 1991). The principal target cell for N. salmonis are hematopoietic cells which, upon infection, undergo proliferative changes leading to a leukemia-like condition with an accompanying anemia (Wongtavatchai et al. 1995).

    Regulation of gene expression by intranuclear transduction of macromolecules such as transcription factors is an alternative to gene therapy for the treatment of numerous diseases. The identification of an effective intranuclear delivery vehicle and pathway for the transport of therapeutic macromolecules across plasma and nuclear membranes, however, has posed a significant challenge. The anti-DNA antibody fragment 3E10 Fv has received attention as a novel molecular delivery vehicle due to its penetration into living cells with specific nuclear localization, absence of toxicity, and successful delivery of therapeutic cargo proteins in vitro and in vivo. Elucidation of the pathway that allows 3E10 Fv to cross cell membranes is critical to the development of new molecular therapies. Here we show that 3E10 Fv penetrates cells through a nucleoside salvage transporter. 3E10 Fv is unable to penetrate into cells deficient in the equilibrative nucleoside transporter ENT2, and reconstitution of ENT2 into ENT2-deficient cells restores 3E10 Fv transport into cell nuclei. Our results represent the first demonstration of protein transport through a nucleoside salvage pathway. We expect that our finding will facilitate a variety of methods of gene regulation in the treatment of human diseases, open up new avenues of research in nucleoside salvage pathways, and enhance our understanding of the pathophysiology of autoimmune diseases.

    Chromosome condensation is critical for accurate inheritance of genetic information. The degree of condensation, which is reflected in the size of the condensed chromosomes during mitosis, is not constant. It is differentially regulated in embryonic and somatic cells. In addition to the developmentally programmed regulation of chromosome condensation, there may be adaptive regulation based on spatial parameters such as genomic length or cell size. We propose that chromosome condensation is affected by a spatial parameter called the chromosome amount per nuclear space, or "intranuclear DNA density." Using Caenorhabditis elegans embryos, we show that condensed chromosome sizes vary during early embryogenesis. Of importance, changing DNA content to haploid or polyploid changes the condensed chromosome size, even at the same developmental stage. Condensed chromosome size correlates with interphase nuclear size. Finally, a reduction in nuclear size in a cell-free system from Xenopus laevis eggs resulted in reduced condensed chromosome sizes. These data support the hypothesis that intranuclear DNA density regulates chromosome condensation. This suggests an adaptive mode of chromosome condensation regulation in metazoans.

    Point of use (POU) household water treatment is increasingly being adopted as a solution for access to safe water. Non-tuberculous Mycobacteria (NTM) are found in water, but there is little research on whether NTM survive POU treatment. Mycobacteria may be removed by multi-barrier treatment systems that combine processes such as coagulation, settling and disinfection. This work evaluated removal of a non-tuberculous Mycobacterium (Mycobaterium terrae) and a Gram-negative non-acid-fast environmental bacterium (Aeromonas hydrophila) by combined coagulation-flocculation disinfection POU treatment. Aeromonas hydrophila showed 7.7 log10 reduction in demand free buffer, 6.8 log10 in natural surface water, and 4 log10 reduction in fecally contaminated surface water. Turbidity after treatment was <1 NTU. There was almost no reduction in levels of viable M. terrae by coagulant-flocculant-disinfectant in natural water after 30 minutes. The lack of Mycobacteria reduction was similar for both combined coagulant-flocculant-disinfectant and hypochlorite alone. A POU coagulant-flocculant-disinfectant treatment effectively reduced A. hydrophila from natural surface waters but not Mycobacteria. These results reinforce previous findings that POU coagulation-flocculation-disinfection is effective against gram-negative enteric bacteria. POU treatment and safe storage interventions may need to take into account risks from viable NTM in treated stored water and consider alternative treatment processes to achieve NTM reductions.

    The human ERCC5/XPG protein is defective in the hereditary genetic disorder xeroderma pigmentosum, group-G. The XPG gene encodes a single-strand DNA endonuclease which is essential for the incision step of nucleotide excision repair for a wide variety of DNA damages. We have shown previously by indirect immunofluorescence and biochemical fractionation that the XPG protein is localized in the nucleus, in discrete foci, and probably associated with the nuclear matrix. However, the intranuclear localization of XPG is markedly altered for a short time after UV irradiation. Here, we report the identification of XPG protein regions involved in the UV response, and its putative nuclear localization signals (NLS) using a B-galactosidase (B-gal) reporter gene system. Control and fusion reporter genes were expressed in Hela S3 cells after CaPO{sub 4} transfection. B-gal protein was detected by indirect immuno-fluorescence using an anti B-gal monoclonal antibody and FITC-labeled goat anti-mouse antiserum. Two NLS peptides of the XPG carboxy-terminal region (AA 1029-1069 and 1146-1186 term) were shown to independently localize B-gal fusion proteins to the nucleus (>90%). The C-terminus peptide was observed to further localize B-gal into nuclear foci and the perinucleolar regions. When B-gal was fused with two copies of the C-terminal NLS, in tandem, B-gal was extensively sublocalized to the perinucleolar regions. Shortly after cell UV irradiation (5 J/m{sup 2}) this B-gal fusion protein became dissociated from the perinucleolar regions whereupon it was distributed throughout the nucleus. Within 6 hours post-irradiation, the fusion protein reassociated again with the perinucleolar regions. These observations confirm and extend a similar UV response of endogenous XPG protein in UV-irradiation human cells. The involvement of XPG protein and its UV responses will be discussed in context of models nuclear matrix and preferential DNA repair in actively transcribed genes.

    Evidence of the pathological roles of matrix metalloproteinases (MMPs) in various neurological disorders has made them attractive therapeutic targets. MMPs disrupt the blood-brain barrier and cause neuronal death and neuroinflammation in acute cerebral ischemia and are critical for angiogenesis during recovery. However, some challenges have to be overcome before MMPs can be further validated as drug targets in stroke injury. Identifying in vivo substrates of MMPs should greatly improve our understanding of the mechanisms of ischemic injury and is critical for providing more precise drug targets. Recent works have uncovered nontraditional roles for MMPs in the cytosol and nucleus. These have shed light on intracellular targets and biological actions of MMPs, adding additional layers of complexity for therapeutic MMP inhibition. In this review, we discussed the recent advances made in understanding nuclear location of MMPs, their regulation of intranuclear sorting, and their intranuclear proteolytic activity and substrates. In particular, we highlighted the roles of intranuclear MMPs in oxidative DNA damage, neuronal apoptosis, and neuroinflammation at an early stage of stroke insult. These novel data point to new putative MMP-mediated intranuclear actions in stroke-induced pathological processes and may lead to novel approaches to treatment of stroke and other neurological diseases.

    Intranuclear rods are aggregates consisting of actin and cofilin that are formed in the nucleus in consequence of chemical or mechanical stress conditions. The formation of rods is implicated in a variety of pathological conditions, such as certain myopathies and some neurological disorders. It is still not well understood what exactly triggers the formation of intranuclear rods, whether other proteins are involved, and what the underlying mechanisms of rod assembly or disassembly are. In this study, Dictyostelium discoideum was used to examine appearance, stages of assembly, composition, stability, and dismantling of rods. Our data show that intranuclear rods, in addition to actin and cofilin, are composed of a distinct set of other proteins comprising actin-interacting protein 1 (Aip1), coronin (CorA), filactin (Fia), and the 34 kDa actin-bundling protein B (AbpB). A finely tuned spatio-temporal pattern of protein recruitment was found during formation of rods. Aip1 is important for the final state of rod compaction indicating that Aip1 plays a major role in shaping the intranuclear rods. In the absence of both Aip1 and CorA, rods are not formed in the nucleus, suggesting that a sufficient supply of monomeric actin is a prerequisite for rod formation. PMID:28074884

    Several muscovy ducks from a free-roaming flock of 65 muscovy and mallard ducks died over a 3-week period. Three muscovy ducks were necropsied. Gross and microscopic changes were compatible with duck virus enteritis, and the virus was isolated. In addition to intranuclear viral inclusion bodies in several tissues, intracytoplasmic inclusion bodies were present in esophageal and cloacal epithelium, By electron microscopy, the membrane-bound intracytoplasmic inclusions were found to contain enveloped herpesvirus, and nuclei contained herpes viral nucleocapsids.

    An epizootic disease in pigeons associated with atypical pneumonia in two persons handling the birds has been studied. Most of the observations made during the work were consistent with the idea that we were dealing with an infection caused by a member of the psittacosis-lymphogranuloma venereum group of viruses. The outbreak was peculiar, however, in that tissues of the diseased pigeons contained many intranuclear inclusions and that the viruses isolated from these birds produced both intranuclear inclusions and elementary bodies in the cytoplasm of cells of chorio-allantoic membranes of the developing egg. Whether the pigeons were simultaneously infected with two viruses or whether the virus of pigeon psittacosis can produce intranuclear inclusions under certain conditions remains to be determined.

    2013-01-01

    Background Commercial fisheries of lumpfish Cyclopterus lumpus have been carried out in Iceland for centuries. Traditionally the most valuable part is the eggs which are harvested for use as a caviar substitute. Previously reported parasitic infections from lumpfish include an undescribed intranuclear microsporidian associated with abnormal kidneys and mortalities in captive lumpfish in Canada. During Icelandic lumpfish fisheries in spring 2011, extensive enlargements to the kidneys were observed in some fish during processing. The aim of this study was to identify the pathogen responsible for these abnormalities. Methods Lumpfish from the Icelandic coast were examined for the causative agent of kidney enlargement. Fish were dissected and used in histological and molecular studies. Results Lumpfish, with various grades of clinical signs, were observed at 12 of the 43 sites sampled around Iceland. From a total of 77 fish examined, 18 had clear clinical signs, the most prominent of which was an extensive enlargement and pallor of the kidneys. The histopathology of the most severely affected fish consisted of extensive degeneration and necrosis of kidney tubules and vacuolar degeneration of the haematopoietic tissue. Intranuclear microsporidians were detected in all organs examined in fish with prominent clinical signs and most organs of apparently healthy fish using the new PCR and histological examination. One or multiple uniformly oval shaped spores measuring 3.12 ± 0.15 × 1.30 ± 0.12 μm were observed in the nucleus of affected lymphocytes and lymphocyte precursor cells. DNA sequencing provided a ribosomal DNA sequence that was strongly supported in phylogenetic analyses in a clade containing other microsporidian parasites from the Enterocytozoonidae, showing highest similarity to the intranuclear microsporidian Nucleospora salmonis. Conclusions Intranuclear microsporidian infections are common in wild caught lumpfish from around the Icelandic

    Renal tubular inclusion bodies are rarely associated with drug administration. The authors describe the finding of renal cortical tubular intranuclear and intracytoplasmic inclusion bodies associated with the oral administration of a norepinephrine/serotonin reuptake inhibitor (NSRI) test article in Sprague-Dawley (SD) rats. Rats were given an NSRI daily for 4 weeks, and kidney histopathologic, ultrastructural pathology, and immunohistochemical examinations were performed. Round eosinophilic intranuclear inclusion bodies were observed histologically in the tubular epithelial cells of the renal cortex in male and female SD rats given the NSRI compound. No evidence of degeneration or necrosis was noted in the inclusion-containing renal cells. By ultrastructural pathology, inclusion bodies consisted of finely granular, amorphous, and uniformly stained nonmembrane-bound material. By immunohistochemistry, inclusion bodies stained positive for d-amino acid oxidase (DAO) protein. In addition, similar inclusion bodies were noted in the cytoplasmic tubular epithelial compartment by ultrastructural and immunohistochemical examination.  This is the first description of these renal inclusion bodies after an NSRI test article administration in SD rats. Such drug-induced renal inclusion bodies are rat-specific, do not represent an expression of nephrotoxicity, represent altered metabolism of d-amino acids, and are not relevant to human safety risk assessment.

    fAter being released from transcription sites, messenger ribonucleoprotein particles (mRNPs) must reach the nuclear pore complexes in order to be translocated to the cytoplasm. Whether the intranuclear movement of mRNPs results largely from Brownian motion or involves molecular motors remains unknown. Here we have used quantitative photobleaching techniques to monitor the intranuclear mobility of protein components of mRNPs tagged with GFP. The results show that the diffusion coefficients of the poly(A)-binding protein II (PABP2) and the export factor TAP are significantly reduced when these proteins are bound to mRNP complexes, as compared with nonbound proteins. The data further show that the mobility of wild-type PABP2 and TAP, but not of a point mutant variant of PABP2 that fails to bind to RNA, is significantly reduced when cells are ATP depleted or incubated at 22°C. Energy depletion has only minor effects on the intranuclear mobility of a 2,000-kD dextran (which corresponds approximately in size to 40S mRNP particles), suggesting that the reduced mobility of PABP2 and TAP is not caused by a general alteration of the nuclear environment. Taken together, the data suggest that the mobility of mRNPs in the living cell nucleus involves a combination of passive diffusion and ATP-dependent processes. PMID:12473688

    Background During infection, successful bacterial clearance is achieved via the host immune system acting in conjunction with appropriate antibiotic therapy. However, it still remains a tip of the iceberg as to where persistent pathogens namely, Burkholderia pseudomallei (B. pseudomallei) reside/hide to escape from host immune sensors and antimicrobial pressure. Methods We used transmission electron microscopy (TEM) to investigate post-mortem tissue sections of patients with clinical melioidosis to identify the localisation of a recently identified gut microbiome, B. pseudomallei within host cells. The intranuclear presence of B. pseudomallei was confirmed using transmission electron microscopy (TEM) of experimentally infected guinea pig spleen tissues and Live Z-stack, and ImageJ analysis of fluorescence microscopy analysis of in vitro infection of A549 human lung epithelial cells. Results TEM investigations revealed intranuclear localization of B. pseudomallei in cells of infected human lung and guinea pig spleen tissues. We also found that B. pseudomallei induced actin polymerization following infection of A549 human lung epithelial cells. Infected A549 lung epithelial cells using 3D-Laser scanning confocal microscopy (LSCM) and immunofluorescence microscopy confirmed the intranuclear localization of B. pseudomallei. Conclusion B. pseudomallei was found within the nuclear compartment of host cells. The nucleus may play a role as an occult or transient niche for persistence of intracellular pathogens, potentially leading to recurrrent episodes or recrudescence of infection. PMID:28045926

    The cell nucleus contains a number of membrane-less organelles or intra-nuclear compartments. These compartments are dynamic structures representing liquid-droplet phases which are only slightly denser than the bulk intra-nuclear fluid. They possess different functions, have diverse morphologies, and are typically composed of RNA (or, in some cases, DNA) and proteins. We analyzed 3005 mouse proteins localized in specific intra-nuclear organelles, such as nucleolus, chromatin, Cajal bodies, nuclear speckles, promyelocytic leukemia (PML) nuclear bodies, nuclear lamina, nuclear pores, and perinuclear compartment and compared them with ~29,863 non-nuclear proteins from mouse proteome. Our analysis revealed that intrinsic disorder is enriched in the majority of intra-nuclear compartments, except for the nuclear pore and lamina. These compartments are depleted in proteins that lack disordered domains and enriched in proteins that have multiple disordered domains. Moonlighting proteins found in multiple intra-nuclear compartments are more likely to have multiple disordered domains. Protein-protein interaction networks in the intra-nuclear compartments are denser and include more hubs compared to the non-nuclear proteins. Hubs in the intra-nuclear compartments (except for the nuclear pore) are enriched in disorder compared with non-nuclear hubs and non-nuclear proteins. Therefore, our work provides support to the idea of the functional importance of intrinsic disorder in the cell nucleus and shows that many proteins associated with sub-nuclear organelles in nuclei of mouse cells are enriched in disorder. This high level of disorder in the mouse nuclear proteins defines their ability to serve as very promiscuous binders, possessing both large quantities of potential disorder-based interaction sites and the ability of a single such site to be involved in a large number of interactions.

    Many parasitic bacteria live in the cytoplasm of multicellular animals, but only a few are known to regularly invade their nuclei. In this study, we describe the novel bacterial parasite "Candidatus Endonucleobacter bathymodioli" that invades the nuclei of deep-sea bathymodiolin mussels from hydrothermal vents and cold seeps. Bathymodiolin mussels are well known for their symbiotic associations with sulfur- and methane-oxidizing bacteria. In contrast, the parasitic bacteria of vent and seep animals have received little attention despite their potential importance for deep-sea ecosystems. We first discovered the intranuclear parasite "Ca. E. bathymodioli" in Bathymodiolus puteoserpentis from the Logatchev hydrothermal vent field on the Mid-Atlantic Ridge. Using primers and probes specific to "Ca. E. bathymodioli" we found this intranuclear parasite in at least six other bathymodiolin species from vents and seeps around the world. Fluorescence in situ hybridization and transmission electron microscopy analyses of the developmental cycle of "Ca. E. bathymodioli" showed that the infection of a nucleus begins with a single rod-shaped bacterium which grows to an unseptated filament of up to 20 microm length and then divides repeatedly until the nucleus is filled with up to 80,000 bacteria. The greatly swollen nucleus destroys its host cell and the bacteria are released after the nuclear membrane bursts. Intriguingly, the only nuclei that were never infected by "Ca. E. bathymodioli" were those of the gill bacteriocytes. These cells contain the symbiotic sulfur- and methane-oxidizing bacteria, suggesting that the mussel symbionts can protect their host nuclei against the parasite. Phylogenetic analyses showed that the "Ca. E. bathymodioli" belongs to a monophyletic clade of Gammaproteobacteria associated with marine metazoans as diverse as sponges, corals, bivalves, gastropods, echinoderms, ascidians and fish. We hypothesize that many of the sequences from this clade

    Incubation of cultured cells under specific conditions induces a dramatic change in the actin organization: induction of intranuclear and/or cytoplasmic actin rods (actin paracrystal-like intracellular structures). We have found that cofilin, a 21-kDa actin-binding protein, is a component of these rods. Antibodies directed against cofilin labeled intranuclear actin rods induced in cells treated with dimethyl sulfoxide or exposed to heat shock and also labeled cytoplasmic actin rods induced in cells incubated in specific salt buffers. Moreover, we found that these actin rods are not stained with fluorescent phalloidin derivatives at all and appear to be right-handed helices, different from straight bundles of F-actin such as stress fibers. In vitro experiments revealed that cofilin and phalloidin compete with each other for binding to F-actin. Since cofilin and phalloidin have the ability to stoichiometrically bind actin molecule in the filament in vitro, the above results seem to suggest that cofilin directly binds to actin molecule in nearly an equimolar ratio in these rods. We call these rods ``actin/cofilin rods.''

We find that a refined description of the neutron skin and of the energy density in the nuclear surface is crucial for the aforementioned observables, and that neither ingredient is sufficient if taken separately. As a by-product, the predictions for removal of several nucleons are also improved by the refined treatment.

    Acid fast staining of sputum smears by microscopy remains the prevalent method for detecting Mycobacterium tuberculosis. The sensitivity of microscopy using acid fast stains requires 10(4) bacilli per ml of sputum. Although fluorescent acid fast stains, such as Auramine-O, show improved sensitivity, almost half of culture-positive TB cases are currently estimated to remain smear-negative. These current diagnosis problems provide impetus for improving staining procedures. We evaluated a novel fluorescent acid-fast staining approach using the nucleic acid-binding dye SYBR(®) Gold on mycobacterial in vitro cultures. The SYBR(®) Gold stain detected 99% of MTB in both actively replicating aerobic and non-replicating hypoxic cultures. Transmission light microscopy with Ziehl-Neelsen fuchsin, and fluorescence microscopy with Auramine-O or Auramine-rhodamine detected only 54%-86% of MTB bacilli. SYBR(®) Gold fluoresces more intensely than Auramine-O, and is highly resistant to fading. The signal to noise ratio is exceptionally high due to a >1000-fold enhanced fluorescence after binding to DNA/RNA, thereby reducing most background fluorescence. Although cost and stability of the dye may perhaps limit its clinical use at this time, these results warrant further research into more nucleic acid dye variants. In the meantime, SYBR(®) Gold staining shows great promise for use in numerous research applications.

    Six strains of mycobacteria,—three human strains, Saranac H-37, T. S., and No. 90, a bovine strain, B-1, a smegma strain, No. 74, and a Saranac strain of B. phlei,—have been made to grow as non-acid-fast organisms by the addition to the culture media of a filtered extract of the chromogenic H-37 strain of B. tuberculosis. The action of the extract produced acceleration of growth of the treated culture, followed by macroscopic and microscopic changes, and differentiation into non-acid-fast forms. The bacterial forms grown from these treated cultures were pleomorphic, usually consisting of cocci and small rods; but branching forms and spore-like bodies also developed. The sterility of the extract causing the changes was demonstrated by frequent control inoculations on various media, including Kendall's K medium; and autoclaved extracts had the same effects as non-autoclaved. After transfer to media suitable for acid growths four of the strains reverted not only to acid-fastness but to their original cultural characteristics, providing evidence that the non-acid-fast forms were specific for the strain.

    The use of a liquid culture system such as MGIT broth has greatly improved the sensitivity of isolating mycobacteria in clinical laboratories. Microscopic visualization of acid fast bacilli (AFB) in the culture positive MGIT broth remains the first routine step for rapidly indicating the presence of mycobacteria. We modified an ultraviolet (UV) light fixation process to increase AFB cells adherence to the slide. The retained haze proportion of a 1-cm circle marked area on the smear slide was quantified after the staining procedure indicating the adherence degree of AFB cells. More AFB cells were preserved on the slide after exposure to UV light of either germicidal lamp or UV crosslinker in a time-dependent manner. We demonstrated both the bovine serum albumin (BSA) in MGIT media and UV light exposure were required for enhancing fixation of AFB cells. While applying to AFB stains for 302 AFB positive MGIT broths in clinics, more AFB cells were retained and observed on smear slides prepared by the modified fixation procedure rather than by the conventional method. The modified fixation procedure was thus recommended for improving the sensitivity of microscopic diagnosis of AFB cells in culture positive MGIT broth. PMID:24586725

    Suppression of nuclear factor-κB (NF-κB) activation, which is best known as a major regulator of innate and adaptive immune responses, is a potent strategy for the treatment of endotoxic sepsis. To inhibit NF-κB functions, we designed the intra-nuclear transducible form of transcription modulation domain (TMD) of RelA (p65), called nt-p65-TMD, which can be delivered effectively into the nucleus without influencing the cell viability, and work as interactomic inhibitors via disruption of the endogenous p65-mediated transcription complex. nt-p65-TMD effectively inhibited the secretion of pro-inflammatory cytokines, including TNF-α, IL-1β, or IL-6 from BV2 microglia cells stimulated by lipopolysaccharide (LPS). nt-p65-TMD did not inhibit tyrosine phosphorylation of signaling mediators such as ZAP-70, p38, JNK, or ERK involved in T cell activation, but was capable of suppressing the transcriptional activity of NF-κB without the functional effect on that of NFAT upon T-cell receptor (TCR) stimulation. The transduced nt-p65-TMD in T cell did not affect the expression of CD69, however significantly inhibited the secretion of T cell-specific cytokines such as IL-2, IFN-γ, IL-4, IL-17A, or IL-10. Systemic administration of nt-p65-TMD showed a significant therapeutic effect on LPS-induced sepsis model by inhibiting pro-inflammatory cytokines secretion. Therefore, nt-p65-TMD can be a novel therapeutics for the treatment of various inflammatory diseases, including sepsis, where a transcription factor has a key role in pathogenesis, and further allows us to discover new functions of p65 under normal physiological condition without genetic alteration. - Highlights: • The nt-p65-TMD is intra-nuclear interactomic inhibitor of endogenous p65. • The nt-p65-TMD effectively inhibited the secretion of pro-inflammatory cytokines. • The excellent therapeutic potential of nt-p65-TMD was confirmed in sepsis model.

    The purpose of this paper is twofold. First, we present the extension of the Liège intranuclear-cascade model to reactions induced by light ions. We describe here the ideas upon which we built our treatment of nucleus-nucleus reactions and we compare the model predictions against a vast set of heterogeneous experimental data. In spite of the discussed limitations of the intranuclear-cascade scheme, we find that our model yields valid predictions for a number of observables and positions itself as one of the most attractive alternatives available to geant4 users for the simulation of light-ion-induced reactions. Second, we describe the c++ version of the code, which is physicswise equivalent to the legacy version, is available in geant4, and will serve as the basis for all future development of the model.

    Recent analyses indicated that autophagy can be regulated via some nuclear transcriptional networks and many important players in the autophagy and other forms of programmed cell death are known to be intrinsically disordered. To this end, we analyzed similarities and differences in the intrinsic disorder distribution of nuclear and non-nuclear proteins related to autophagy. We also looked at the peculiarities of the distribution of the intrinsically disordered autophagy-related proteins in various intra-nuclear organelles, such as the nucleolus, chromatin, Cajal bodies, nuclear speckles, promyelocytic leukemia (PML) nuclear bodies, nuclear lamina, nuclear pores, and perinucleolar compartment. This analysis revealed that the autophagy-related proteins constitute about 2.5% of the non-nuclear proteins and 3.3% of the nuclear proteins, which corresponds to a substantial enrichment by about 32% in the nucleus. Curiously, although, in general, the autophagy-related proteins share similar characteristics of disorder with a generic set of all non-nuclear proteins, chromatin and nuclear speckles are enriched in the intrinsically disordered autophagy proteins (29 and 37% of these proteins are disordered, respectively) and have high disorder content at 0.24 and 0.27, respectively. Therefore, our data suggest that some of the nuclear disordered proteins may play important roles in autophagy.

    Paraspeckles are sub-nuclear domains that are nucleated by long noncoding RNA Neat1. While interaction of protein components of paraspeckles and Neat1 is understood, there is limited information on the interaction of non-structural RNA components with paraspeckles. Here, by varying paraspeckle number and size, we investigate how paraspeckles influence the nuclear organization of their non-structural RNA component Ctn RNA. Our results show that Ctn RNA remains nuclear-retained in the absence of intact paraspeckles, suggesting that they do not regulate nuclear retention of Ctn RNA. In the absence of Neat1, Ctn RNA continues to interact with paraspeckle protein NonO to form residual nuclear foci. In addition, in the absence of Neat1-nucleated paraspeckles, a subset of Ctn RNA localizes to the perinucleolar regions. Concomitant with increase in number of paraspeckles, transcriptional reactivation resulted in increased number of paraspeckle-localized Ctn RNA foci. Similar to Neat1, proteasome inhibition altered the localization of Ctn RNA, where it formed enlarged paraspeckle-like foci. Super-resolution structured illumination microscopic analyses revealed that in paraspeckles, Ctn RNA partially co-localized with Neat1, and displayed a more heterogeneous intra-paraspeckle localization. Collectively, these results show that while paraspeckles do not influence nuclear retention of Ctn RNA, they modulate its intranuclear compartmentalization. PMID:27665741

    Correlative data are presented here on the developmental history, dynamics, histochemistry, and fine structure of intranuclear rodlets in chicken sympathetic neurons from in vivo material and long-term organized tissue cultures. The rodlets consist of bundles of ∼70 ± 10 A proteinaceous filaments closely associated with ∼0.4–0.8 µ spheroidal, granulofibrillar (gf) bodies of a related nature. These bodies are already present in the developing embryo a week or more in advance of the rodlets. In early formative stages rodlets consist of small clusters of aligned filaments contiguous with the gf-bodies. As neuronal differentiation progresses these filaments increase in number and become organized into well-ordered polyhedral arrays. Time-lapse cinemicrography reveals transient changes in rodlet contour associated with intrinsic factors, changes in form and position of the nucleolus with respect to the rodlet, and activity of the gf-bodies. With the electron microscope filaments may be seen extending between the nucleolus, gf-bodies, and rodlets; nucleoli display circumscribed regions with fine structural features and staining reactions reminiscent of those of gf-bodies, We suggest that the latter may be derivatives of the nucleolus and that the two may act together in the assemblage and functional dynamics of the rodlet. The egress of rodlet filaments into the cytoplasm raises the possibility that these might represent a source of the cell's filamentous constituents. PMID:4901373

    Actin, which is normally depleted in the nuclei of somatic cells, accumulates in high amounts in giant nuclei of amphibian oocytes. The supramolecular organization and functions of this nuclear pool of actin in growing vertebrate oocyte are controversial. Here, we investigated the role of nuclear actin in the maintenance of the spatial architecture of intranuclear structures in avian and amphibian growing oocytes. A meshwork of filamentous actin was not detected in freshly isolated or fixed oocyte nuclei of Xenopus, chicken or quail. We found that the actin meshwork inside the oocyte nucleus could be induced by phalloidin treatment. Actin polymerization is demonstrated to be required to stabilize the specific spatial organization of nuclear structures in avian and amphibian growing oocytes. In experiments with the actin depolymerizing drugs cytochalasin D and latrunculin A, we showed that disassembly of nuclear actin polymers led to chromosome condensation and their transportation to a limited space within the oocyte nucleus. Experimentally induced “collapsing” of chromosomes and nuclear bodies, together with global inhibition of transcription, strongly resembled the process of karyosphere formation during oocyte growth.

    Although African swine fever virus (ASFV) replicates in viral cytoplasmic factories, the presence of viral DNA within the host cell nucleus has been previously reported to be essential for productive infection. Herein, we described, for the first time, the intranuclear distribution patterns of viral DNA replication events, preceding those that occur in the cytoplasmic compartment. Using BrdU pulse-labelling experiments, newly synthesized ASFV genomes were exclusively detected inside the host cell nucleus at the early phase of infection, both in swine monocyte-derived macrophages (MDMs) and Vero cells. From 8hpi onwards, BrdU labelling was only observed in ASFV cytoplasmic factories. Our results also show that ASFV specifically activates the Ataxia Telangiectasia Mutated Rad-3 related (ATR) pathway in ASFV-infected swine MDMs from the early phase of infection, most probably because ASFV genome is recognized as foreign DNA. Morphological changes of promyelocytic leukaemia nuclear bodies (PML-NBs), nuclear speckles and Cajal bodies were also found in ASFV-infected swine MDMs, strongly suggesting the viral modulation of cellular antiviral responses and cellular transcription, respectively. As described for other viral infections, the nuclear reorganization that takes place during ASFV infection may also provide an environment that favours its intranuclear replication events. Altogether, our results contribute for a better understanding of ASFV replication strategies, starting with an essential intranuclear DNA replication phase which induces host nucleus changes towards a successful viral infection.

    Immunohistochemical examination with the antiserum against neuronal NO synthase and cystathionine β-synthase was used to study the following two pools of interneurons in Wistar rats at various periods after the development of renovascular hypertension: intranuclear interneurons (lying in the projection of the solitary nucleus, reticular gigantocellular nucleus, and parvocellular nucleus) and 2 groups of internuclear interneurons (small interneurons, area 50-300 μ(2); and large interneurons, area above 350 μ(2)). Intranuclear and internuclear interneurons probably play a role in the central mechanisms of hemodynamics regulation. These interneurons differ by not only in topochemical parameters, but also functional properties (different resistances to BP changes). Intranuclear interneurons are characterized by high sensitivity of the gas transmitter systems to a continuous increase in BP, which results in remodeling and dysfunction of the bulbar part of the cardiovascular center. Large internuclear interneurons demonstrate a strong reaction to BP rise, which confirms their involvement into hemodynamics regulation. By contrast, small internuclear interneurons retain their characteristics in arterial hypertension and probably perform an integrative function.

    A number of changes occur in the oxytocin (OT) system during gestation, such as increases in hypothalamic OT mRNA, increased neural lobe and systemic OT, and morphological and electrophysiological changes in OT-containing magnocellular neurons, suggestive of altered neuronal sensitivity, which may be mediated by ovarian steroids. Because central norepinephrine (NE) and histamine (HA) are potent stimulators of OT release during parturition and lactation, the present study investigated the effects of central noradrenergic and histaminergic receptor activation on systemic (NE, HA) and intranuclear (NE) OT release in pregnant rats and in ovariectomized rats treated with ovarian steroids. Plasma OT levels in late gestation were significantly higher compared with all other groups, and neither adrenergic nor histaminergic receptor blockade decreased these elevated levels. Furthermore, the alpha-adrenergic agonist phenylephrine, but not histamine, stimulated systemic OT release to a significantly greater extent in late gestation than in midpregnant, ovariectomized, or steroid-treated females. Although basal extracellular OT levels in the paraventricular nucleus, as measured with microdialysis, were unchanged during pregnancy or steroid treatment, noradrenergic receptor stimulation of intranuclear OT release was significantly elevated in midgestation females compared with all other groups. These studies indicate that sensitivity of intranuclear and systemic OT release to noradrenergic receptor activation differentially varies during the course of gestation.

    There was a spontaneous outbreak of mycobacteriosis in fancy veiltail guppies, Lebistes reticulatus, raised on an ornamental fish farm in Venezuela. The clinical signs included listlessness, emaciation, spinal curvature, sunken eyes and loss of colour. Numerous acid-fast bacteria, identified as Mycobacterium species, were detected in smears from the kidneys, liver, mesentery and spleen of the fish, from fresh faecal material, and from the unborn embryos of infected gravid females. The bacteria were eradicated by the addition of kanamycin sulphate to the water at a concentration of 50 ppm, the dose being repeated on four occasions with 48 hours between each dose. Fifteen days after the treatment, none of the clinical signs described were detected in any of the treated fish. The offspring born to treated females were healthy and normal, and did not harbour acid-fast bacteria.

    The new version (incl4.6) of the Liège intranuclear cascade (INC) model for the description of spallation reactions is presented in detail. Compared to the standard version (incl4.2), it incorporates several new features, the most important of which are: (i) the inclusion of cluster production through a dynamical phase space coalescence model, (ii) the Coulomb deflection for entering and outgoing charged particles, (iii) the improvement of the treatment of Pauli blocking and of soft collisions, (iv) the introduction of experimental threshold values for the emission of particles, (v) the improvement of pion dynamics, (vi) a detailed procedure for the treatment of light-cluster-induced reactions taking care of the effects of binding energy of the nucleons inside the incident cluster and of the possible fusion reaction at low energy. Performances of the new model concerning nucleon-induced reactions are illustrated by a comparison with experimental data covering total reaction cross sections, neutron, proton, pion, and composite double-differential cross-sections, neutron multiplicities, residue mass and charge distributions, and residue recoil velocity distributions. Whenever necessary, the incl4.6 model is coupled to the ABLA07 de-excitation model and the respective merits of the two models are then tentatively disentangled. Good agreement is generally obtained in the 200 MeV to 2 GeV range. Below 200 MeV and down to a few tens of MeV, the total reaction cross section is well reproduced and differential cross sections are reasonably well described. The model is also tested for light-ion induced reactions at low energy, below 100 MeV incident energy per nucleon. Beyond presenting the update of the incl4.2 model, attention has been paid to applications of the new model to three topics for which some particular aspects are discussed for the first time. The first topic is the production of clusters heavier than alpha particle. It is shown that the energy spectra of

    According to text book definition, parasites reduce the fitness of their hosts whereas mutualists provide benefits. But biotic and abiotic factors influence symbiotic interactions, thus under certain circumstances parasites can provide benefits and mutualists can harm their host. Here we addressed the question which intrinsic biotic factors shape a symbiosis and are crucial for the outcome of the interaction between the obligate intranuclear bacterium Holospora caryophila (Alphaproteobacteria; Rickettsiales) and its unicellular eukaryotic host Paramecium biaurelia (Alveolata; Ciliophora). The virulence of H. caryophila, i.e., the negative fitness effect on host division and cell number, was determined by growth assays of several P. biaurelia strains. The performances of genetically identical lines either infected with H. caryophila or symbiont-free were compared. Following factors were considered as potentially influencing the outcome of the interaction: (1) host strain, (2) parasite strain, and (3) growth phases of the host. All three factors revealed a strong effect on the symbiosis. In presence of H. caryophila, the Paramecium density in the stationary growth phase decreased. Conversely, a positive effect of the bacteria during the exponential phase was observed for several host × parasite combinations resulting in an increased growth rate of infected P. biaurelia. Furthermore, the fitness impact of the tested endosymbionts on different P. biaurelia lines was not only dependent on one of the two involved strains but distinct for the specific combination. Depending on the current host growth phase, the presence of H. caryophila can be harmful or advantageous for P. biaurelia. Thus, under the tested experimental conditions, the symbionts can switch from the provision of benefits to the exploitation of host resources within the same host population and a time-span of less than 6 days.

    ABSTRACT Coccidia are protozoan parasites that cause significant human disease and are of major agricultural importance. Cryptosporidium spp. cause diarrhea in humans and animals, while Toxoplasma causes disseminated infections in fetuses and untreated AIDS patients. Eimeria is a major pathogen of commercial chickens. Oocysts, which are the infectious form of Cryptosporidium and Eimeria and one of two infectious forms of Toxoplasma (the other is tissue cysts in undercooked meat), have a multilayered wall. Recently we showed that the inner layer of the oocyst walls of Toxoplasma and Eimeria is a porous scaffold of fibers of β-1,3-glucan, which are also present in fungal walls but are absent from Cryptosporidium oocyst walls. Here we present evidence for a structural role for lipids in the oocyst walls of Cryptosporidium, Toxoplasma, and Eimeria. Briefly, oocyst walls of each organism label with acid-fast stains that bind to lipids in the walls of mycobacteria. Polyketide synthases similar to those that make mycobacterial wall lipids are abundant in oocysts of Toxoplasma and Eimeria and are predicted in Cryptosporidium. The outer layer of oocyst wall of Eimeria and the entire oocyst wall of Cryptosporidium are dissolved by organic solvents. Oocyst wall lipids are complex mixtures of triglycerides, some of which contain polyhydroxy fatty acyl chains like those present in plant cutin or elongated fatty acyl chains like mycolic acids. We propose a two-layered model of the oocyst wall (glucan and acid-fast lipids) that resembles the two-layered walls of mycobacteria (peptidoglycan and acid-fast lipids) and plants (cellulose and cutin).

    The purpose of the paper is mainly to test the validity of the Liège intranuclear cascade (INCL) model in calculating the cross sections of proton-induced reactions for cosmogenic nuclei using the newly compiled database of proton cross sections. The model calculations of 3He display the rising tendency of cross sections with the increase of energy, in accordance with the experimental data. Meanwhile, the differences between the theoretical results and experimental data of production cross sections (10Be and 26Al) are generally within a factor of 3, meaning that the INCL model works quite well for the proton-induced reactions. Based on the good agreement, we predict the production cross sections of 26Al from reactions n + 27Al, n + 28Si, and n + 40Ca and those of 10Be from reactions n + 16O and n + 28Si. The results also show a good agreement with a posteriori excitation functions.

    Purpose: To inhibit DNA double-strand break repair in tumor cells by delivery of a single-chain antibody variable region fragment (ScFv 18-2) to the cell nucleus. ScFv 18-2 binds to a regulatory region of the DNA-dependent protein kinase (DNA-PK), an essential enzyme in the nonhomologous end-joining pathway, and inhibits DNA end-joining in a cell-free system and when microinjected into single cells. Development as a radiosensitizer has been limited by the lack of a method for intranuclear delivery to target cells. We investigated a delivery method based on folate receptor-mediated endocytosis. Methods and Materials: A recombinant ScFv 18-2 derivative was conjugated to folate via a scissile disulfide linker. Folate-ScFv 18-2 was characterized for its ability to be internalized by tumor cells and to influence the behavior of ionizing radiation-induced repair foci. Radiosensitization was measured in a clonogenic survival assay. Survival curves were fitted to a linear-quadratic model, and between-group differences were evaluated by an F test. Sensitization ratios were determined based on mean inhibitory dose. Results: Human KB and NCI-H292 lung cancer cells treated with folate-conjugated ScFv 18-2 showed significant radiosensitization (p < 0.001). Sensitization enhancement ratios were 1.92 {+-} 0.42 for KB cells and 1.63 {+-} 0.13 for NCI-H292 cells. Studies suggest that treatment inhibits repair of radiation-induced DSBs, as evidenced by the persistence of {gamma}-H2AX-stained foci and by inhibition of staining with anti-DNA-PKcs phosphoserine 2056. Conclusions: Folate-mediated endocytosis is an effective method for intranuclear delivery of an antibody-derived DNA repair inhibitor.

    Cancer cell-selective, nuclear targeting is expected to enhance the therapeutic efficacy of a myriad of antineoplastic drugs, particularly those whose pharmacodynamic site of action is the nucleus. In this study, a steroid-macromolecular bioconjugate based on PEG-linked 17β-Estradiol (E2) was appended to intrinsically cell-penetrable multiwalled carbon nanotubes (MWCNTs) for intranuclear drug delivery and effective breast cancer treatment, both in vitro and in vivo. Taking Doxorubicin (DOX) as a model anticancer agent, we tried to elucidate how E2 appendage influences the cell internalization, intracellular trafficking, and antitumor efficacy of the supramolecularly complexed drug. We observed that the combination of DOX with E2-PEG-MWCNTs not only facilitated nuclear targeting through an estrogen receptor (ER)-mediated pathway but also deciphered to a synergistic anticancer response in vivo. The antitumor efficacy of DOX@E2-PEG-MWCNTs in chemically breast cancer-induced female rats was approximately 18, 17, 5, and 2 times higher compared to the groups exposed to saline, drug-deprived E2-PEG-MWCNTs, free DOX, and DOX@m-PEG-MWCNTs, respectively. While free DOX treatment induced severe cardiotoxicity in animals, animals treated with DOX@m-PEG-MWCNTs and DOX@E2-PEG-MWCNTs were devoid of any perceivable cardiotoxicity, hepatotoxicity, and nephrotoxicity. To the best of our knowledge, this is the first instance in which cancer cell-selective, intranuclear drug delivery, and, subsequently, effective in vivo breast cancer therapy has been achieved using estrogen-appended MWCNTs as the molecular transporter.

    During a histological survey of razor clam Ensis arcuatus (Jeffreys, 1865) from Galicia (NW Spain), basophilic inclusion bodies were observed in epithelial cells of the digestive gland. Transmission electron microscopy revealed the intranuclear position of these inclusions containing viral particles with icosahedral symmetry. Size and symmetry of these unenveloped virus particles suggest similarities to the families Papillomaviridae and Polyomaviridae which have been described as causing a viral gametocytic hypertrophy in oysters Crassostrea virginica and C. gigas. This is the first report of viral particles in E. arcuatus.

    One of the main factors for high workload in pulmonary pathology in developing countries is the relatively large proportion of tuberculosis (TB) cases which can be detected with high throughput using automated approaches. TB is caused by Mycobacterium tuberculosis, which appears as thin, rod-shaped acid-fast bacillus (AFB) in Ziehl-Neelsen (ZN) stained sputum smear samples. In this paper, we present an algorithm for automatic detection of AFB in digitized images of ZN stained sputum smear samples under a light microscope. A key component of the proposed algorithm is the enhancement of raw input image using a novel anisotropic tubular filter (ATF) which suppresses the background noise while simultaneously enhancing strong anisotropic features of AFBs present in the image. The resulting image is then segmented using color features and candidate AFBs are identified. Finally, a support vector machine classifier using morphological features from candidate AFBs decides whether a given image is AFB positive or not. We demonstrate the effectiveness of the proposed ATF method with two different feature sets by showing that the proposed image analysis pipeline results in higher accuracy and F1-score than the same pipeline with standard median filtering for image enhancement.

    Neuro-Sweet disease (NSD) is Sweet disease with central nervous system (CNS) involvement. To the best of our knowledge, the present case report is the first to describe NSD complicated by endogenous infection with Mycobacterium tuberculosis. The present case report describes a male patient who developed NSD-induced meningitis, which initially manifested as a fever, headache and neck stiffness. Painful erythematous plaques subsequently developed on his face, neck and upper trunk. Brain magnetic resonance imaging was performed and the results were normal, whereas modified acid-fast stain analysis of the cerebrospinal fluid (CSF) provided a positive result. The patient was thus diagnosed with viral meningitis and tuberculosis. However, subsequent skin biopsy results demonstrated neutrophilic infiltration into the dermis without vasculitis, and subsequent human leukocyte antigen typing was positive for Cw1 and negative for B51 and the patient was diagnosed with NSD. Following treatment with corticosteroids, and antiviral and anti-tuberculotic agents, the clinical symptoms were reduced and the previously abnormal findings in the CSF examinations and associated laboratory data were improved. The present case indicates that the diagnosis of NSD is not easily achieved, and early skin biopsy is vital to ensure a fast and effective diagnosis. In addition to systemic corticosteroids, comprehensive treatment is also recommended for patients with NSD complicated by additional complex medical problems.

Components of the spliceosomes were localized by in situ hybridization with biotinylated U1 and U2 DNA probes and by immunolabeling with Y12 anti-Sm monoclonal antibody, whereas poly(A)+ RNAs were localized by specific binding of biotinylated poly(dT) probe. At early stages of nuclear transformation, the distribution of small nuclear RNPs was similar to that previously described in non-infected nuclei (Visa, N., Puvion-Dutilleul, F., Bachellerie, J.P. and Puvion, E., Eur. J. Cell Biol. 60, 308-321, 1993; Visa, N., Puvion-Dutilleul, F., Harper, F., Bachellerie, J. P. and Puvion, E., Exp. Cell Res. 208, 19-34, 1993). As the infection progresses, the large virus-induced inclusion body consists of a central storage site of functionally inactive viral genomes surrounded by a peripheral shell formed by clusters of interchromatin granules, compact rings and a fibrillogranular network in which are embedded the viral single-stranded DNA accumulation sites. Spliceosome components and poly(A)+ RNAs were then exclusively detected over the clusters of interchromatin granules and the fibrillogranular network whereas the viral single-stranded DNA accumulation sites and compact rings remained unlabeled, thus appearing to not be directly involved in splicing. Our data, therefore, suggest that the fibrillogranular network, in addition to being the site of viral transcription, is also a major site of viral RNA splicing. Like the clusters of interchromatin granules, which had been already involved in spliceosome assembly, they could also have a role in the sorting of viral spliced polyadenylated mRNAs before export to the cytoplasm. The compact rings, which contain non-polyadenylated viral RNA, might accumulate the non-used portions of the viral transcripts resulting from differential poly(A)+ site selection.

    Chronic alcoholism is known to alter the morphology of the hippocampus, an important region of cognitive function in the brain. Therefore, to understand the effect of chronic alcoholism on hippocampal neural cells, we employed a mouse model of chronic alcoholism and quantified intranuclear nanoscale structural alterations in these cells. Transmission electron microscopy (TEM) images of hippocampal neurons were obtained, and the degree of structural alteration in terms of mass density fluctuation was determined using the light-localization properties of optical media generated from TEM imaging. The results, which were obtained at length scales ranging from ~30 to 200 nm, show that 10–12 week-old mice fed a Lieber–DeCarli liquid (alcoholic) diet had a higher degree of structural alteration than control mice fed a normal diet without alcohol. The degree of structural alteration became significantly distinguishable at a sample length of ~100 nm, which is the typical length scale of the building blocks of cells, such as DNA, RNA, proteins and lipids. Interestingly, different degrees of structural alteration at such length scales suggest possible structural rearrangement of chromatin inside the nuclei in chronic alcoholism.

    In order to try to improve the results of direct smear microscopy, we used the mucus-digesting quality of chitin in tuberculosis (TB) laboratories. For this purpose, a total of 430 sputum specimens were processed by the N-acetyl-L-cysteine concentration, sodium hypochlorite (NaOCl) liquefaction, chitin sedimentation, and direct microscopy methods. Then, the smear sensitivity for acid-fast bacillus detection by chitin-treated sputum was compared with the sensitivity of smears prepared by other methods. Our results showed that the chitin solution took less time to completely homogenize the mucoid sputum than did the N-acetyl-L-cysteine and NaOCl methods. The N-acetyl-L-cysteine concentration method demonstrated sensitivity and specificity levels of 83 and 97%, respectively. In comparison, the sensitivity of chitin sedimentation was 80%, with a specificity of 96.7%. The NaOCl liquefaction method showed a sensitivity of 78%, with a specificity of 96%. Finally, the sensitivity of direct microscopy was lower than those of the other tested methods and was only 46%, with a specificity of 90%. The chitin and NaOCl liquefaction methods are both easy to perform, and they do not require additional equipment (centrifuges). Also, our results demonstrated that the chitin method is less time-consuming than the NaOCl method, since only 30 min of incubation is required to bring complete sedimentation of bacilli in chitin-treated sputum whereas the NaOCl method needs 10 to 12 h to give the same results in the same sputum specimens. Therefore, the chitin liquefaction and sedimentation method may provide better results in TB laboratories of developing countries than the N-acetyl-L-cysteine concentration, NaOCl overnight sedimentation, and direct smear microscopy methods.

    In a multicenter study involving three reference centers for mycobacteria, the rate of recovery of acid-fast bacilli (AFB) and the mean time to their detection from clinical specimens was determined by using the Mycobacteria Growth Indicator Tube (MGIT). These parameters were compared to those assessed by the radiometric BACTEC 460 TB system and by cultivation on solid media. Clinical specimens (n = 1,500) were pretreated with N-acetyl-L-cysteine (NALC)-NaOH. The contamination rates for MGITs were 2.0% (center 1), 13.8% (center 2), and 6.1% (center 3). A total of 180 mycobacterial isolates were detected (M. tuberculosis complex, n = 113; nontuberculous mycobacteria [NTM], n = 67). When using a combination of liquid and solid media (the current "gold standard" for culture), MGIT plus solid media detected 156 (86.7%) of the isolates, whereas BACTEC plus solid media recovered 168 (93.3%) of all AFB. Between these two gold standards there was no statistically significant difference (P > 0.05). The combination of MGIT plus BACTEC detected 171 (95.0%) of all isolates (compared with MGIT plus solid media, P < 0.01; compared with BACTEC plus solid media, P > 0.05). Considering the efficacies of the different media separately, MGIT was superior to solid media (although not significantly; P > 0.05) in detecting AFB but was inferior to the BACTEC system (P < 0.01). The mean time to the detection of M. tuberculosis complex was 9.9 days with MGIT, 9.7 days with BACTEC, and 20.2 days with solid media. NTM needed, on average, 11.9, 13.0, and 22.2 days to appear by the three methods, respectively. In conclusion, MGIT proved to be a valuable alternative to the radiometric cultivation system.

    The clinical and radiological features of pulmonary melioidosis can mimic tuberculosis. We prospectively evaluated 118 patients with suspected pulmonary tuberculosis who were acid-fast bacilli (AFB) smear negative at Udon Thani Hospital, northeast Thailand. Culture of residual sputum from AFB testing was positive for Burkholderia pseudomallei in three patients (2.5%; 95% confidence interval [CI] 0.5-7.3%). We propose that in melioidosis-endemic areas, residual sputum from AFB testing should be routinely cultured for B. pseudomallei.

    Fluorescent acid-fast microscopy (FAM) was used to enumerate intracellular Mycobacterium avium, Mycobacterium intracellulare, and Mycobacterium scrofulaceum in the ciliated phagocytic protozoan Tetrahymena pyriformis. There was a linear relationship between FAM and colony counts of M. avium cells both from cultures and within protozoa. The Ziehl-Neelsen acid-fast stain could not be used to enumerate intracellular mycobacteria because uninfected protozoa contained acid-fast, bacterium-like particles. Starved, 7-day-old cultures of T. pyriformis transferred into fresh medium readily phagocytized M. avium, M. intracellulare, and M. scrofulaceum. Phagocytosis was rapid and reached a maximum in 30 min. M. avium, M. intracellulare, and M. scrofulaceum grew within T. pyriformis, increasing by factors of 4- to 40-fold after 5 days at 30 degrees C. Intracellular M. avium numbers remained constant over a 25-day period of growth (by transfer) of T. pyriformis. Intracellular M. avium cells also survived protozoan encystment and germination. The growth and viability of T. pyriformis were not affected by mycobacterial infection. The results suggest that free-living phagocytic protozoa may be natural hosts and reservoirs for M. avium, M. intracellulare, and M. scrofulaceum.

    The sigma-1 receptor (SIGMAR1) is now known to be one of the endoplasmic reticulum (ER) chaperones, which participate in the degradation of misfolded proteins in cells via the ER-related degradation machinery linked to the ubiquitin-proteasome pathway. Mutations of the SIGMAR1 gene are implicated in the pathogenesis of familial frontotemporal lobar degeneration and motor neuron disease. Involvement of ER dysfunction in the formation of inclusion bodies in various neurodegenerative diseases has also become evident. We performed immunohistochemical staining to clarify the localization of SIGMAR1 in the brains of patients with neurodegenerative disorders, including trans-activation response DNA protein 43 (TDP-43) proteinopathy, tauopathy, α-synucleinopathy, polyglutamine disease and intranuclear inclusion body disease (INIBD). Double-immunocytofluorescence and Western blot analyses of cultured cells were also performed to investigate the role of SIGMAR1 using a specific exportin 1 inhibitor, leptomycin B and an ER stress inducer, thapsigargin. SIGMAR1 was consistently shown to be co-localized with neuronal nuclear inclusions in TDP-43 proteinopathy, five polyglutamine diseases and INIBD, as well as in intranuclear Marinesco bodies in aged normal controls. Cytoplasmic inclusions in neurons and glial cells were unreactive for SIGMAR1. In cultured cells, immunocytofluorescent study showed that leptomycin B and thapsigargin were shown to sequester SIGMAR1 within the nucleus, acting together with p62. This finding was also supported by immunoblot analysis. These results indicate that SIGMAR1 might shuttle between the nucleus and the cytoplasm. Neurodegenerative diseases characterized by neuronal nuclear inclusions might utilize the ER-related degradation machinery as a common pathway for the degradation of aberrant proteins.

  19. Design of a microfluidic device to quantify dynamic intra-nuclear deformation during cell migration through confining environments

    The ability of cells to migrate through tissues and interstitial space is an essential factor during development and tissue homeostasis, immune cell mobility, and in various human diseases. Deformation of the nucleus and its associated lamina during 3-D migration is gathering increasing interest in the context of cancer metastasis, with the underlying hypothesis that a softer nucleus, resulting from reduced levels of lamin A/C, may aid tumour spreading. However, current methods to study the migration of cells in confining three dimensional (3-D) environments are limited by their imprecise control over the confinement, physiological relevance, and/or compatibility with high resolution imaging techniques. We describe the design of a polydimethylsiloxane (PDMS) microfluidic device composed of channels with precisely-defined constrictions mimicking physiological environments that enable high resolution imaging of live and fixed cells. The device promotes easy cell loading and rapid, yet long-lasting (>24 hours) chemotactic gradient formation without the need for continuous perfusion. Using this device, we obtained detailed, quantitative measurements of dynamic nuclear deformation as cells migrate through tight spaces, revealing distinct phases of nuclear translocation through the constriction, buckling of the nuclear lamina, and severe intranuclear strain. Furthermore, we found that lamin A/C-deficient cells exhibited increased and more plastic nuclear deformations compared to wild-type cells but only minimal changes in nuclear volume, implying that low lamin A/C levels facilitate migration through constrictions by increasing nuclear deformability rather than compressibility. The integration of our migration devices with high resolution time-lapse imaging provides a powerful new approach to study intracellular mechanics and dynamics in a variety of physiologically-relevant applications, ranging from cancer cell invasion to immune cell recruitment.

    We report two separate naturally occurring cases of fatal herpesviral disease in Cooper's Hawks (Accipiter cooperii). Gross lesions included splenomegaly and hepatomegaly, with diffuse pale mottling or scattered small white foci. Histologic lesions included splenic and hepatic necrosis associated with eosinophilic intranuclear inclusion bodies characteristic of herpesvirus. In one case, necrosis and inclusions were also noted in bone marrow, thymus, bursa of Fabricius, thyroid gland, parathyroid gland, ceca, and the enteric system. Transmission electron microscopy demonstrated viral particles typical of herpesvirus within hepatocyte nuclei and budding from the nuclear membrane. Herpesviral DNA was amplified via polymerase chain reaction (PCR) of paraffin-embedded liver and spleen, and sequence data were consistent with columbid herpesvirus-1, an alphaherpesvirus of Rock Pigeons (Columba livia). PCR results provide evidence that this disease is transmitted to raptors via Rock Pigeons, most likely through ingestion of Rock Pigeons as prey.

    Inclusion body disease of cranes was the cause of death in 17 immature and mature cranes of 5 different species in Wisconsin. A herpesvirus of unknown origin was the apparent cause. An isolate of this herpesvirus was used to experimentally infect 3 species of cranes. Macroscopic and microscopic lesions associated with naturally acquired and experimentally induced disease were essentially identical. Multifocal hepatic and splenic necrosis was found in all cranes evaluated. Necrosis of the gastrointestinal tract, thymus, and bursa of Fabricius also was seen in some of the cranes. Eosinophilic intranuclear inclusion bodies often were commonly associated with hepatic lesions, sometimes with the splenic lesions, and rarely with the thymic or gastrointestinal tract lesions. The lesions of this inclusion body disease were similar to those reported for cranes in Austria from which a crane herpesvirus was isolated.

    We report two unusual autopsy cases with frontotemporal lobar degeneration (FTLD) that were hyperphosphorylated-tau- and TAR DNA binding protein 43 (TDP-43)- negative. The behavioral symptoms in both cases were compatible with frontotemporal dementia, but they exhibited more prominent speech and language related symptoms than previously reported. Moreover, they displayed a short duration of the disease; the male case had a disease onset age of 45 years, and duration of 5 years, and the female case suffered even shorter disease duration and a later onset of the symptoms, at the age of 67 years. Moreover, the motor functions had deteriorated in different ways in these cases. The male patient showed progressive motor symptoms, weakness of extremities and bulbar muscles suggesting motor neuron disease with a muscle biopsy supporting neurogenic deficits, whereas the female patient exhibited dyskinesias and tremor with progressive swallowing disorders. The father of the male case displayed dementia of similar type at the age of 68 years. In both cases, neuropathological examination showed fused-in sarcoma (FUS)-positive pathology. The male patient had intensely FUS-positive cytoplasmic and intranuclear inclusions that resembled the characteristics previously reported in FTLD FUS, whereas the female patient did not exhibit any cytoplasmic inclusions but had roundish, dense FUS-positive intranuclear inclusions. She also displayed a plethora of other pathologies including α-synuclein, hyperphosphorylated-tau, β-amyloid aggregation and some neuronal polyglutamine aggregation (1C2) but no well-demarcated inclusions were observed. We conclude that clinical phenotypes of FUS pathologies also include elderly patients and are more variable with motor and speech disorders than previously reported.

    Differential modulation of NF-κB during meningococcal infection is critical in innate immune response to meningococcal disease. Non-invasive isolates of Neisseria meningitidis provoke a sustained NF-κB activation in epithelial cells. However, the hyperinvasive isolates of the ST-11 clonal complex (ST-11) only induce an early NF-κB activation followed by a sustained activation of JNK and apoptosis. We show that this temporal activation of NF-κB was caused by specific cleavage at the C-terminal region of NF-κB p65/RelA component within the nucleus of infected cells. This cleavage was mediated by the secreted 150 kDa meningococcal ST-11 IgA protease carrying nuclear localisation signals (NLS) in its α-peptide moiety that allowed efficient intra-nuclear transport. In a collection of non-ST-11 healthy carriage isolates lacking NLS in the α-peptide, secreted IgA protease was devoid of intra-nuclear transport. This part of iga polymorphism allows non-invasive isolates lacking NLS, unlike hyperinvasive ST-11 isolates of N. meningitides habouring NLS in their α-peptide, to be carried asymptomatically in the human nasopharynx through selective eradication of their ability to induce apoptosis in infected epithelial cells.

    Ubiquitin-positive tau-negative neuronal cytoplasmic inclusions and dystrophic neurites are common pathological features in frontotemporal lobar degeneration (FTLD) with or without symptoms of motor neuron disease and in amyotrophic lateral sclerosis (ALS). Using biochemical and immunohistochemical analyses, we have identified a TAR DNA-binding protein of 43 kDa (TDP-43), a nuclear factor that functions in regulating transcription and alternative splicing, as a component of these structures in FTLD. Furthermore, skein-like inclusions, neuronal intranuclear inclusions, and glial inclusions in the spinal cord of ALS patients are also positive for TDP-43. Dephosphorylation treatment of the sarkosyl insoluble fraction has shown that abnormal phosphorylation takes place in accumulated TDP-43. The common occurrence of intracellular accumulations of TDP-43 supports the hypothesis that these disorders represent a clinicopathological entity of a single disease, and suggests that they can be newly classified as a proteinopathy of TDP-43.

    Neuronal intermediate filament inclusion disease (NIFID), a rare form of frontotemporal lobar degeneration (FTLD), is characterized neuropathologically by focal atrophy of the frontal and temporal lobes, neuronal loss, gliosis, and neuronal cytoplasmic inclusions (NCI) containing epitopes of ubiquitin and neuronal intermediate filament proteins. Recently, the 'fused in sarcoma' (FUS) protein (encoded by the FUS gene) has been shown to be a component of the inclusions of familial amyotrophic lateral sclerosis with FUS mutation, NIFID, basophilic inclusion body disease, and atypical FTLD with ubiquitin-immunoreactive inclusions (aFTLD-U). To further characterize FUS proteinopathy in NIFID, and to determine whether the pathology revealed by FUS immunohistochemistry (IHC) is more extensive than α-internexin, we have undertaken a quantitative assessment of ten clinically and neuropathologically well-characterized cases using FUS IHC. The densities of NCI were greatest in the dentate gyrus (DG) and in sectors CA1/2 of the hippocampus. Anti-FUS antibodies also labeled glial inclusions (GI), neuronal intranuclear inclusions (NII), and dystrophic neurites (DN). Vacuolation was extensive across upper and lower cortical layers. Significantly greater densities of abnormally enlarged neurons and glial cell nuclei were present in the lower compared with the upper cortical laminae. FUS IHC revealed significantly greater numbers of NCI in all brain regions especially the DG. Our data suggest: (1) significant densities of FUS-immunoreactive NCI in NIFID especially in the DG and CA1/2; (2) infrequent FUS-immunoreactive GI, NII, and DN; (3) widely distributed vacuolation across the cortex, and (4) significantly more NCI revealed by FUS than α-internexin IHC.

    Background Smear-negative pulmonary tuberculosis (PTB) is common and difficult to diagnose. In this study, we investigated the diagnostic value of nucleic acid amplification testing and sequencing combined with acid-fast bacteria (AFB) staining of needle biopsy lung tissues for patients with suspected smear-negative PTB. Methods Patients with suspected smear-negative PTB who underwent percutaneous transthoracic needle biopsy between May 1, 2012, and June 30, 2015, were enrolled in this retrospective study. Patients with AFB in sputum smears were excluded. All lung biopsy specimens were fixed in formalin, embedded in paraffin, and subjected to acid-fast staining and tuberculous polymerase chain reaction (TB-PCR). For patients with positive AFB and negative TB-PCR results in lung tissues, probe assays and 16S rRNA sequencing were used for identification of nontuberculous mycobacteria (NTM). The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and diagnostic accuracy of PCR and AFB staining were calculated separately and in combination. Results Among the 220 eligible patients, 133 were diagnosed with TB (men/women: 76/57; age range: 17–80 years, confirmed TB: 9, probable TB: 124). Forty-eight patients who were diagnosed with other specific diseases were assigned as negative controls, and 39 patients with indeterminate final diagnosis were excluded from statistical analysis. The sensitivity, specificity, PPV, NPV, and accuracy of histological AFB (HAFB) for the diagnosis of smear-negative were 61.7% (82/133), 100% (48/48), 100% (82/82), 48.5% (48/181), and 71.8% (130/181), respectively.

    It is well known that the cell nucleus is organized in structural and functional compartments involved in transcription, RNA processing and protein modifications such as conjugation with SUMO-1 and proteolysis. Promyelocytic leukaemia (PML) bodies are dynamic nuclear structures that concentrate PML protein, SUMO-1 and several sumoylated and non-sumoylated protein regulators of nuclear functions. PML bodies and their associated CBP has been involved in neuronal survival. By light and electron microscopy immunocytochemistry and in situ hybridization we reported the presence, in non-pathological conditions, of a large PML-nuclear inclusion (PML-NI) in human supraoptic neurons. This inclusion appears as a single nuclear structure composed of a capsule enriched in PML, SUMO-1 and CBP proteins and a central lattice of filaments immunoreactive for class III beta-tubulin, ubiquitinated proteins and proteasomes. Furthermore, the PML-NI concentrates the SUMO-conjugating enzyme E2 (UBC9). The PML-NI may be considered a nuclear factory involved in sumoylation and proteolysis via ubiquitin-proteasome system, two nuclear pathways engaged in the control of the nucleoplasmic concentration of active transcriptional regulators. Interestingly, the structural and molecular organization of the PML-NI is related to the Marinesco bodies, age-associated ubiquitinated intranuclear inclusions, and to the intranuclear rodlets enriched in class III beta-tubulin, which are nuclear structures markedly decreased in Alzheimer's disease.

    In progressive multifocal leukoencephalopathy, JC virus-infected oligodendroglia display 2 distinct patterns of intranuclear viral inclusions: full inclusions in which progeny virions are present throughout enlarged nuclei and dot-shaped inclusions in which virions are clustered in subnuclear domains termed "promyelocytic leukemia nuclear bodies" (PML-NBs). Promyelocytic leukemia nuclear bodies may serve a scaffolding role in viral progeny production. We analyzed the formation process of intranuclear viral inclusions by morphometry and assessed PML-NB alterations in the brains of 2 patients with progressive multifocal leukoencephalopathy. By immunohistochemistry, proliferating cell nuclear antigen was most frequently detected in smaller nuclei; cyclin A was detected in larger nuclei. This suggests an S-to-G2 cell cycle transition in infected cells associated with nuclear enlargement. Sizes of PML-NBs were variable, but they were usually either small speckles 200 to 400 nm in diameter or distinct spherical shells with a diameter of 1 μm or more. By confocal microscopy, JC virus capsid proteins were associated with both small and large PML-NBs, but disruption of large PML-NBs was observed by ground-state depletion fluorescence nanoscopy. Clusters of progeny virions were also detected by electron microscopy. Our data suggest that, in progressive multifocal leukoencephalopathy, JC virus produces progeny virions in enlarging oligodendrocyte nuclei in association with growing PML-NBs and with cell cycle transition through an S-to-G2-like state.

    Previous reports indicate that mutations within the Autographa californica nucleopolyhedrosis virus FP25K gene (open reading frame 61) significantly reduce incorporation of enveloped nucleocapsids into viral occlusions. We report that FP25K is a nucleocapsid protein of both the budded virus (BV) and occluded virus (ODV), and we describe the effects of two FP25K mutations (480-1 [N-terminal truncation] and FP-betagal [C-terminal fusion]) on the expression and cellular localization of ODV-E66 and ODV-E25. Significantly decreased amounts of ODV-E66 are detected in cells infected with 480-1 or FP-betagal viral mutants, even though during FP-betagal infection, steady-state levels of ODV-E66 transcripts remain unchanged. While ODV-E66 is normally detected in intranuclear microvesicles and ODV envelopes by 24 h postinfection (p.i.), ODV-E66 remains cytosolic throughout infection in cells infected with 480-1 virus (up to 96 h p.i.), and its intranuclear localization is not detected until 96 h p.i. in cells infected with the FP-betagal mutant virus. The nuclear localization of ODV-E25 is not affected during infection by the FP-betagal mutant; however, its trafficking is significantly delayed during infection by the 480-1 mutant. Temporal Western blot analyses of cell lysates show that both 480-1 and FP-betagal mutant virus infections result in altered accumulation patterns of several structural proteins, including gp67, BV/ODV-E26, and the major capsid protein p39. In addition to BV/ODV-E26, ODV-E66 and gp67 may interact with FP25K, and ODV-E25 and p39 may also be components of a protein complex containing ODV-E66 and FP25K. Together, these data suggest that FP25K and its associated protein complex(es) may play an important role in the targeting and intracellular transport of viral proteins during infection.

    The objective of the study is to compare the performance of conventional fluorescence microscopy (CFM) and light-emitting diode (LED) fluorescence microscopy (FM) for detection of acid-fast bacilli (AFB) in clinical samples. We included AFB smears, stained using the auramine O method and blindly examined with both CFM and LED-FM. Culture results were used as reference for evaluating the reliability of the FM. We included 180 culture positive specimens and an equal number of culture negative specimens. Sensitivities for the CFM and LED-FM were 79.4% and 82.2%, respectively. Both microscopes had a high specificity (97.2%). The negative-positive (>1 cross) inter-reader agreement of LED-FM and CFM was excellent. Therefore, detection of scanty AFB was higher with LED-FM. Both microscopes were equivalent with respect to time required to read smears. Although it was not faster than CFM, the higher detection of scanty AFB smears combined with ease of use supports the consideration of LED microscopy by all tuberculosis diagnostic laboratories, as a replacement for conventional fluorescence microscopes.

  11. Herpesviral inclusion body disease in owls and falcons is caused by the pigeon herpesvirus (columbid herpesvirus 1).

    Gailbreath, Katherine L; Oaks, J Lindsay

    2008-04-01

    A herpesviral disease of Rock Pigeons (Columba livia), called "inclusion body disease" or "inclusion body hepatitis," was first described in the 1940s. The disease involves hepatic and splenic necrosis with associated intranuclear inclusion bodies and occurs primarily in young squabs. A similar herpesviral disease occurs in falcons and owls. Serologic and restriction endonuclease digestion studies indicate that herpesviruses from pigeons, falcons, and owls are very closely related and that most reported cases of disease in falcons and owls involve prior documented or possible ingestion of pigeons. These findings led to the hypothesis that an endemic herpesvirus of pigeons may be causing disease in falcons and owls. In order to test this hypothesis, we sequenced a fragment of the herpesviral DNA polymerase gene from naturally infected owls, falcons, and pigeons with inclusion body disease collected between 1991 and 2006. Sequences from all three sources were almost identical, and we therefore propose that the usual agent of inclusion body hepatitis in owls and falcons is columbid herpesvirus 1.

    The polyglutamine (polyQ) diseases are a group of genetically and clinically heterogeneous neurodegenerative diseases, characterized by the expansion of polyQ sequences in unrelated disease proteins, which form different types of neuronal aggregates. The aim of this study was to characterize the aggregation pathology in the brainstem of spinocerebellar ataxia type 2 (SCA2) and 3 (SCA3) patients. For good recognition of neurodegeneration and rare aggregates, we employed 100 µm PEG embedded brainstem sections, which were immunostained with the 1C2 antibody, targeted at polyQ expansions, or with an antibody against p62, a reliable marker of protein aggregates. Brainstem areas were scored semiquantitatively for neurodegeneration, severity of granular cytoplasmic staining (GCS) and frequency of neuronal nuclear inclusions (NNI). SCA2 and SCA3 tissue exhibited the same aggregate types and similar staining patterns. Several brainstem areas showed statistically significant differences between disease groups, whereby SCA2 showed more severe GCS and SCA3 showed more numerous NNI. We observed a positive correlation between GCS severity and neurodegeneration in SCA2 and SCA3 and an inverse correlation between the frequency of NNI and neurodegeneration in SCA3. Although their respective disease proteins are unrelated, SCA2 and SCA3 showed the same aggregate types. Apparently, the polyQ sequence alone is sufficient as a driver of protein aggregation. This is then modified by protein context and intrinsic properties of neuronal populations. The severity of GCS was the best predictor of neurodegeneration in both disorders, while the inverse correlation of neurodegeneration and NNI in SCA3 tissue implies a protective role of these aggregates.

    ,; Lowenstern, J. B.

    2014-01-01

    Melt inclusions are small droplets of silicate melt that are trapped in minerals during their growth in a magma. Once formed, they commonly retain much of their initial composition (with some exceptions) unless they are re-opened at some later stage. Melt inclusions thus offer several key advantages over whole rock samples: (i) they record pristine concentrations of volatiles and metals that are usually lost during magma solidification and degassing, (ii) they are snapshots in time whereas whole rocks are the time-integrated end products, thus allowing a more detailed, time-resolved view into magmatic processes (iii) they are largely unaffected by subsolidus alteration. Due to these characteristics, melt inclusions are an ideal tool to study the evolution of mineralized magma systems. This chapter first discusses general aspects of melt inclusions formation and methods for their investigation, before reviewing studies performed on mineralized magma systems.

    Hepatocyte nuclear factor 4 (HNF-4) is a prominent member of the family of liver-enriched transcription factors, playing a role in the expression of a large number of liver-specific genes. We report here that HNF-4 is a phosphoprotein and that phosphorylation at tyrosine residue(s) is important for its DNA-binding activity and, consequently, for its transactivation potential both in cell-free systems and in cultured cells. Tyrosine phosphorylation did not affect the transport of HNF-4 from the cytoplasm to the nucleus but had a dramatic effect on its subnuclear localization. HNF-4 was concentrated in distinct nuclear compartments, as evidenced by in situ immunofluorescence and electron microscopy. This compartmentalization disappeared when tyrosine phosphorylation was inhibited by genistein. The correlation between the intranuclear distribution of HNF-4 and its ability to activate endogenous target genes demonstrates a phosphorylation signal-dependent pathway in the regulation of transcription factor activity.

    Autographa californica nucleopolyhedrovirus (AcMNPV) orf93 (ac93) is a highly conserved uncharacterized gene that is found in all of the sequenced baculovirus genomes except for Culex nigripalpus NPV. In this report, using bioinformatics analyses, ac93 and odv-e25 (ac94) were identified as baculovirus core genes and thus p33-ac93-odv-e25 represent a cluster of core genes. To investigate the role of ac93 in the baculovirus life cycle, an ac93 knockout AcMNPV bacmid was constructed via homologous recombination in Escherichia coli. Fluorescence and light microscopy showed that the AcMNPV ac93 knockout did not spread by infection, and titration assays confirmed a defect in budded virus (BV) production. However, deletion of ac93 did not affect viral DNA replication. Electron microscopy indicated that ac93 was required for the egress of nucleocapsids from the nucleus and the formation of intranuclear microvesicles, which are precursor structures of occlusion-derived virus (ODV) envelopes. Immunofluorescence analyses showed that Ac93 was concentrated toward the cytoplasmic membrane in the cytoplasm and in the nuclear ring zone in the nucleus. Western blot analyses showed that Ac93 was associated with both nucleocapsid and envelope fractions of BV, but only the nucleocapsid fraction of ODV. Our results suggest that ac93, although not previously recognized as a core gene, is one that plays an essential role in the formation of the ODV envelope and the egress of nucleocapsids from the nucleus.

    Acute promyelocytic leukemia (APL) cells contain one of five chimeric retinoic acid α-receptor (RARα) genes (X-RARα) created by chromosomal translocations or deletion; each generates a fusion protein thought to transcriptionally repress RARα target genes and block myeloid differentiation by an incompletely understood mechanism. To gain spatiotemporal insight into these oncogenic processes, we employed fluorescence microscopy and fluorescence recovery after photobleaching (FRAP). Fluorescence microscopy demonstrated that the intracellular localization of each of the X-RARα proteins was distinct from that of RARα and established which portion(s) of each X-RARα protein—X, RAR, or both—contributed to its altered localization. Using FRAP, we demonstrated that the intranuclear mobility of each X-RARα was reduced compared to that of RARα. In addition, the mobility of each X-RARα was reduced further by ligand addition, in contrast to RARα, which showed no change in mobility when ligand was added. Both the reduced baseline mobility of X-RARα and the ligand-induced slowing of X-RARα could be attributed to the protein interaction domain contained within X. RXRα aberrantly colocalized within each X-RARα; colocalization of RXRα with promyelocytic leukemia (PML)-RARα resulted in reduced mobility of RXRα. Thus, X-RARα may interfere with RARα through its aberrant nuclear dynamics, resulting in spatial and temporal sequestration of RXRα and perhaps other nuclear receptor coregulators critical for myeloid differentiation.

    Two types of intranuclear capsids have been recovered from human cytomegalovirus (HCMV, strain AD169)-infected cells. By analogy with strain Colburn (simian CMV) particles, these have been designated as A- and B-capsids. Both types of capsids are composed of proteins with molecular weights of 153,000 (major capsid protein), 34,000 (minor capsid protein), 28,000, and 11,000 (smallest capsid protein). In addition to these species, B-capsids contain a 36,000-molecular-weight (36K) protein which has been designated as the HCMV "assembly protein," based on its similarities to counterparts in strain Colburn CMV (i.e., 37K protein) and herpes simplex virus (i.e., VP22a/p40/NC-3/ICP35e). Peptide comparisons established that the assembly protein of HCMV B-capsids and the 36K protein that distinguishes HCMV noninfectious enveloped particles from virions are the same, providing direct evidence that noninfectious enveloped particles are enveloped B-capsids.

    Replication stress induced by 24 and 48h exposure to 2.5mM hydroxyurea (HU) increased the activity of poly(ADP-ribose) polymerase-2 (PARP-2; EC 2.4.2.30) in root meristem cells of Vicia faba. An increase in the number of PARP-2 foci was accompanied by their delocalization from peripheral areas to the interior of the nucleus. Our results indicate that the increase in PARP-2 was connected with an increase in S139-phosphorylated H2AX histones. The findings suggest the possible role of PARP-2 in replication stress. We also confirm that the intranuclear location of PARP-2 depends on the duration of HU-induced replication stress, confirming the role of PARP-2 as an indicator of stress intensity. Finally, we conclude that the more intense the HU-mediated replication stress, the greater the probability of PARP-2 activation or H2AXS139 phosphorylation, but also the greater the chance of increasing the efficiency of repair processes and a return to normal cell cycle progression.

    Rational: The role of Cryptosporidium as an agent of human diarrhea has been redefined over the past decade following recognition of the strong association between cases of cryptosporidiosis and immune deficient individuals (such as those with AIDS). Purpose: The purpose of this study is to determine the prevalence of enteric parasites and to compare the diagnostic utility of stool enzyme-linked immunosorbent assay (ELISA) with various modifications of acid-fast (AF) staining in detection of Cryptosporidium in stool samples of diarrheic patients. Materials and Methods: Stool samples from 186 cases comprising of 93 HIV seropositive and 93 seronegative patients were included. These were subjected to routine and microscopic examination as well as various modifications of AF staining for detection of coccidian parasites and ELISA for the detection of Cryptosporidium. Results: The prevalence of enteric parasites was 54.8% and of Cryptosporidium was 17.2% in HIV seropositive patients while it was 29.0% and 5.4%, respectively in seronegative patients. Of the 186 cases, 33 cases (17.7%) were positive for Cryptosporidium by stool ELISA as compared to 21 (11.3%) by modified AF staining (gold standard) showing sensitivity and specificity of 100% and 92.7%, respectively. The maximum cases of Cryptosporidium (21; 11.3%) were detected by AF staining using 3% acid alcohol. Conclusion: ELISA is a simple, useful, and rapid tool for detection of Cryptosporidium in stool, especially for large scale population studies. However, the role of modified AF staining in detection of Cryptosporidium and other coccidian parasites is important. Based on the results of various modifications of AF staining, the present study recommends the use of 3% acid alcohol along with 10% H2SO4. PMID:25250230

    The idiopathic inflammatory myopathies are a group of rare disorders that share many similarities. These include dermatomyositis (DM), polymyositis (PM), necrotizing myopathy (NM), and sporadic inclusion body myositis (IBM). Inclusion body myositis is the most common idiopathic inflammatory myopathy after age 50 and it presents with chronic proximal leg and distal arm asymmetric mucle weakness. Despite similarities with PM, it is likely that IBM is primarily a degenerative disorder rather than an inflammatory muscle disease. Inclusion body myositis is associated with a modest degree of creatine kinase (CK) elevation and an abnormal electromyogram demonstrating an irritative myopathy with some chronicity. The muscle histopathology demonstrates inflammatory exudates surrounding and invading nonnecrotic muscle fibers often times accompanied by rimmed vacuoles. In this chapter, we review sporadic IBM. We also examine past, essentially negative, clinical trials in IBM and review ongoing clinical trials. For further details on DM, PM, and NM, the reader is referred to the idiopathic inflammatory myopathies chapter. PMID:23117948

    The Autographa californica nuclear polyhedrosis virus da26 gene codes for an envelope protein of both budded virus (BV) and occlusion derived virus (ODV). Western blot and temporal analysis of infected cell extracts detected a protein of 26 kDa by 4 h postinfection (p.i.). The amount of protein increased by 16 h p.i. and remained at high levels throughout infection. By 36 h p.i. several additional immunoreactive proteins were detected which migrated at approximately 18 kDa and remained through 96 h p.i. Western blot analysis of purified virus envelope and nucleocapsid preparations revealed that both the 26- and 18-kDa proteins are structural proteins of the envelope of BV and ODV. Immunoelectron microscopy performed at a time when only the 26-kDa species of the protein was present confirmed that the protein located to ODV envelope. The protein was named BV/ODV-E26 to designate incorporation into viral progeny, envelope location, and apparent molecular weight. Studies designed to follow localization of BV/ODV-E26 demonstrated that early in infection, the protein was incorporated into cytoplasmic vesicles and by 16 h p.i., BV/ODV-E26 was detected in the nucleus associated with virus-induced intranuclear microvesicles and ODV envelope. Coimmunoprecipitation and yeast two-hybrid assays showed that BV/ODV-E26 and FP25K were capable of interacting with each other to form a complex and coimmunoprecipitation assays indicated that cellular actin was a third component of this complex. Together, these data suggest that FP25K and cellular actin may participate in the regulation, or movement through the cell, of baculovirus proteins and/or virus nucleocapsids.

    Insect hexamerins have long been known as storage proteins that are massively synthesized by the larval fat body and secreted into hemolymph. Following the larval-to-pupal molt, hexamerins are sequestered by the fat body via receptor-mediated endocytosis, broken up, and used as amino acid resources for metamorphosis. In the honey bee, the transcript and protein subunit of a hexamerin, HEX 70a, were also detected in ovaries and testes. Aiming to identify the subcellular localization of HEX 70a in the female and male gonads, we used a specific antibody in whole mount preparations of ovaries and testes for analysis by confocal laser-scanning microscopy. Intranuclear HEX 70a foci were evidenced in germ and somatic cells of ovarioles and testioles of pharate-adult workers and drones, suggesting a regulatory or structural role. Following injection of the thymidine analog EdU we observed co-labeling with HEX 70a in ovariole cell nuclei, inferring possible HEX 70a involvement in cell proliferation. Further support to this hypothesis came from an injection of anti-HEX 70a into newly ecdysed queen pupae where it had a negative effect on ovariole thickening. HEX 70a foci were also detected in ovarioles of egg laying queens, particularly in the nuclei of the highly polyploid nurse cells and in proliferating follicle cells. Additional roles for this storage protein are indicated by the detection of nuclear HEX 70a foci in post-meiotic spermatids and spermatozoa. Taken together, these results imply undescribed roles for HEX 70a in the developing gonads of the honey bee and raise the possibility that other hexamerins may also have tissue specific functions.

    Conventional toughening agents are typically rubbery materials or small molecular weight molecules, which mostly sacrifice the intrinsic properties of a matrix such as modulus, strength, and thermal stability as side effects. On the other hand, high modulus inclusions tend to reinforce elastic modulus very efficiently, but not the strength very well. For example, mechanical reinforcement with inorganic inclusions often degrades the composite toughness, encountering a frequent catastrophic brittle failure triggered by minute chips and cracks. Thus, toughening generally conflicts with mechanical reinforcement. Carbon nanotubes have been used as efficient reinforcing agents in various applications due to their combination of extraordinary mechanical, electrical, and thermal properties. Moreover, nanotubes can elongate more than 20% without yielding or breaking, and absorb significant amounts of energy during deformation, which enables them to also be an efficient toughening agent, as well as excellent reinforcing inclusion. Accordingly, an improved toughening method is provided by incorporating nanotubular inclusions into a host matrix, such as thermoset and thermoplastic polymers or ceramics without detrimental effects on the matrix's intrinsic physical properties.

    Identifying the flavour of neutral B mesons production is one of the most important components needed in the study of time-dependent CP violation. The harsh environment of the Large Hadron Collider makes it particularly hard to succeed in this task. We present an inclusive flavour-tagging algorithm as an upgrade of the algorithms currently used by the LHCb experiment. Specifically, a probabilistic model which efficiently combines information from reconstructed vertices and tracks using machine learning is proposed. The algorithm does not use information about underlying physics process. It reduces the dependence on the performance of lower level identification capacities and thus increases the overall performance. The proposed inclusive flavour-tagging algorithm is applicable to tag the flavour of B mesons in any proton-proton experiment.

    Inclusion practices and special education can be transformed by using a disability studies perspective, which constructs differences as natural, acceptable, and ordinary. Although inclusion is a moral imperative in promoting social justice, some inclusive practices continue to marginalize students with disabilities. A truly inclusive school reflects a democratic philosophy whereby all students are valued, educators normalize difference through differentiated instruction, and the school culture reflects an ethic of caring and community.

    There is a growing body of neurological, cognitive, and social psychological research to suggest the possibility of positive transfer effects from structured musical engagement. In particular, there is evidence to suggest that engagement in musical activities may impact on social inclusion (sense of self and of being socially integrated). Tackling social exclusion and promoting social inclusion are common concerns internationally, such as in the UK and the EC, and there are many diverse Government ministries and agencies globally that see the arts in general and music in particular as a key means by which social needs can be addressed. As part of a wider evaluation of a national, Government-sponsored music education initiative for Primary-aged children in England (“Sing Up”), opportunity was taken by the authors, at the request of the funders, to assess any possible relationship between (a) children's developing singing behavior and development and (b) their social inclusion (sense of self and of being socially integrated). Subsequently, it was possible to match data from n = 6087 participants, drawn from the final 3 years of data collection (2008–2011), in terms of each child's individually assessed singing ability (based on their singing behavior of two well-known songs to create a “normalized singing score”) and their written responses to a specially-designed questionnaire that included a set of statements related to children's sense of being socially included to which the children indicated their level of agreement on a seven-point Likert scale. Data analyses suggested that the higher the normalized singing development rating, the more positive the child's self-concept and sense of being socially included, irrespective of singer age, sex and ethnicity.

  9. Can We Build Inclusion?

    PubMed

    Kirkeby, Inge Mette; Grangaard, Sidse

    2016-01-01

    Inclusion of children with special needs in kindergartens and preschools may be approached from different angles. This paper raises the question of whether the physical framework of kindergartens makes any difference for daily life at the kindergarten at all, and whether it can support inclusion of some children with special needs. Hence the title - can we build inclusion? In the literature of Universal Design, accommodation and design features seldom reflect the less visible disabilities. The paper is based on a research project initiated to investigate how more or less space influences daily pedagogical practice in general. Twelve interviews were conducted with experienced teachers from twelve different kindergartens with different amounts of space, varying from a ratio of 2.1 m2 play area per child to 5.5 m2. The results indicated that, for a group of children with special needs in particular, the amount of space is crucial. This group consisted of children who were socially very extrovert, and who maybe were noisy, easily provoked, and quick to get involved in arguments with other children. Alternatively, children in the group were very restrained and withdrawn in social interaction. Based on the answers in the interviews, we found support for answering the question in the title in the affirmative; we can build inclusion! This is because the teachers' experience indicated that, if there was sufficient space per child, there were fewer conflicts and the children managed to stay in the same activity for a much longer period. Sufficient space made it possible to divide the children into smaller groups, and use any secluded space. Therefore, it was much easier for other children to include some children with special needs. Accordingly, we can say that, sufficient space per child and an adequate layout and furnishing of the kindergarten is an advantage for all children. This is a clear example of Universal Design in which architectural

  10. N-terminal sequences from Autographa californica nuclear polyhedrosis virus envelope proteins ODV-E66 and ODV-E25 are sufficient to direct reporter proteins to the nuclear envelope, intranuclear microvesicles and the envelope of occlusion derived virus.

    Baculovirus occlusion-derived virus (ODV) derives its envelope from an intranuclear membrane source. N-terminal amino acid sequences of the Autographa californica nuclear polyhedrosis virus (AcMNPV) envelope proteins, ODV-E66 and ODV-E25 (23 and 24 amino acids, respectively) are highly hydrophobic. Recombinant viruses that express the two N-terminal amino acid sequences fused to green fluorescent protein (23GFP or 24GFP) provided visual markers to follow protein transport and localization within the nucleus during infection. Autoflourescence was first detected along the cytoplasmic periphery of the nucleus and subsequently localized as foci to discrete locations within the nucleus. Immunoelectron microscopy confirmed that these foci predominantly contained intranuclear microvesicles and the reporter fusion proteins were also detected in cytoplasmic membranes near the nucleus, and the outer and inner nuclear membrane. Therefore, these defined hydrophobic domains are sufficient to direct native and fusion proteins to induced membrane microvesicles within a baculovirus-infected cell nucleus and the viral envelope. In addition, these data suggest that movement of these proteins into the nuclear envelope may initiate through cytoplasmic membranes, such as endoplasmic reticulum, and that transport into the nucleus may be mediated through the outer and inner nuclear membrane.

  11. Inclusive fitness in agriculture

    PubMed Central

    Kiers, E. Toby; Denison, R. Ford

    2014-01-01

    Trade-offs between individual fitness and the collective performance of crop and below-ground symbiont communities are common in agriculture. Plant competitiveness for light and soil resources is key to individual fitness, but higher investments in stems and roots by a plant community to compete for those resources ultimately reduce crop yields. Similarly, rhizobia and mycorrhizal fungi may increase their individual fitness by diverting resources to their own reproduction, even if they could have benefited collectively by providing their shared crop host with more nitrogen and phosphorus, respectively. Past selection for inclusive fitness (benefits to others, weighted by their relatedness) is unlikely to have favoured community performance over individual fitness. The limited evidence for kin recognition in plants and microbes changes this conclusion only slightly. We therefore argue that there is still ample opportunity for human-imposed selection to improve cooperation among crop plants and their symbionts so that they use limited resources more efficiently. This evolutionarily informed approach will require a better understanding of how interactions among crops, and interactions with their symbionts, affected their inclusive fitness in the past and what that implies for current interactions.

    Differential inclusive-jet cross sections have been measured in photoproduction for boson virtualities Q^2 < 1 GeV^2 with the ZEUS detector at HERA using an integrated luminosity of 300 pb^-1. Jets were identified in the laboratory frame using the k_T, anti-k_T or SIScone jet algorithms. Cross sections are presented as functions of the jet pseudorapidity, eta(jet), and the jet transverse energy, E_T(jet). Next-to-leading-order QCD calculations give a good description of the measurements, except for jets with low E_T(jet) and high eta(jet). The cross sections have the potential to improve the determination of the PDFs in future QCD fits. Values of alpha_s(M_Z) have been extracted from the measurements based on different jet algorithms. In addition, the energy-scale dependence of the strong coupling was determined.

    From bone and wood to concrete and carbon fibre, composites are ubiquitous natural and synthetic materials. Eshelby’s inclusion theory describes how macroscopic stress fields couple to isolated microscopic inclusions, allowing prediction of a composite’s bulk mechanical properties from a knowledge of its microstructure. It has been extended to describe a wide variety of phenomena from solid fracture to cell adhesion. Here, we show experimentally and theoretically that Eshelby’s theory breaks down for small liquid inclusions in a soft solid. In this limit, an isolated droplet’s deformation is strongly size-dependent, with the smallest droplets mimicking the behaviour of solid inclusions. Furthermore, in opposition to the predictions of conventional composite theory, we find that finite concentrations of small liquid inclusions enhance the stiffness of soft solids. A straightforward extension of Eshelby’s theory, accounting for the surface tension of the solid-liquid interface, explains our experimental observations. The counterintuitive stiffening of solids by fluid inclusions is expected whenever inclusion radii are smaller than an elastocapillary length, given by the ratio of the surface tension to Young’s modulus of the solid matrix. These results suggest that surface tension can be a simple and effective mechanism to cloak the far-field elastic signature of inclusions.

    The intranuclear coccidian parasite of Testudines (TINC) is responsible for significant disease in turtles and tortoises causing high mortality and affecting several threatened species. Diagnostic testing has been limited to relatively labor intensive and expensive pan-coccidial PCR and sequencing techniques. A qPCR assay targeting a specific and conserved region of TINC 18S rRNA was designed. The qPCR reaction was run on samples known to be TINC positive and the results were consistent and analytically specific. The assay was able to detect as little as 10 copies of target DNA in a sample. Testing of soil and invertebrates was negative and did not provide any further insights into life cycles. This assay was used to identify TINC in a novel host species, the critically endangered Arakan forest turtle (Heosemys depressa).

This post-mortem investigation revealed a consistent neuronal loss in the substantia nigra, pontine nuclei, reticulotegmental nucleus of the pons, superior and inferior olives, in the area of the excitatory burst neurons for horizontal saccades, raphe interpositus nucleus and vestibular nuclei. Immunoreactive intranuclear neuronal inclusions were present in all degenerated and apparently spared brainstem nuclei and immunoreactive axonal inclusions were observed in all brainstem fiber tracts of the HD patients. Degeneration of brainstem nuclei can account for a number of less well-understood clinical HD symptoms (ie, cerebellar, oculomotor and vestibular symptoms), while the formation of axonal aggregates may represent a crucial event in the cascades of pathological events leading to neurodegeneration in HD.

  10. Histopathology of mallards dosed with lead and selected substitute shot

    1967-01-01

    The histopathological response of male game farm mallards fed lead, three types of plastic-coated lead, two lead-magnesium alloys, iron, copper, zinc-coated iron, and molybdenum-coated iron shot was studied. Mallards fed lead, plastic-coated lead, or lead-magnesium alloy shot developed a similar pathological response, including the formation of acid-fast intranuclear inclusion bodies in the kidneys. Birds fed iron or molybdenum-coated iron shot developed hemosiderosis of the liver. Two of four mallards fed zinc-coated iron shot also developed hemosiderosis of the liver. No lesions were found in mallards fed copper shot.

    A sick mourning dove (Zenuidura macroura) collected in Maryland with 2 lead shot in the gizzard showed acid-fast intranuclear inclusion bodies in the kidney tubular cells. The liver and the tibia contained 72 ppm and 187 ppm lead (wet weight) respectively. Four gizzards from 62 doves killed by hunters contained lead shot. The lead content of 43 dove livers ranged from 0.4-14.0 ppm (wet weight); 40 of these doves were collected by hunters, and the other 3 were dying of trichomoniasis.

  13. Neuronal loss in familial frontotemporal dementia with ubiquitin-positive, tau-negative inclusions.

    PubMed

    Cairns, N J; Brännström, T; Khan, M N; Rossor, M N; Lantos, P L

    2003-06-01

    The neuronal density in the frontal, temporal, and parietal lobes was determined in nine cases of familial frontotemporal dementia with ubiquitin-positive, tau-negative inclusions (FTDU). The mean age at onset was 56.9 +/- 2.2 years and the duration of disease was 6.7 +/- 0.5 years. The mean age at death was 63.6 +/- 2.2 years. There was substantial loss (34%) of brain weight (877 +/- 73 g) in the familial cases in comparison with 10 normal aged controls (1326 +/- 50 g, P < 0.001). All of the familial FTDU cases showed atrophy of the frontal, temporal, and parietal lobes; neuronal loss; vacuolation in superficial laminae; reactive astrocytosis; and ubiquitin-positive, tau-negative intracytoplasmic and intranuclear inclusions and dystrophic neurites in varying sites and numbers. Neuronal loss was estimated in nine cases of familial FTDU and in 10 aged controls using a stereological probe, the optical "disector," and a computerized stereology system (CAST-Grid, Olympus, Denmark). There was a significant reduction in neuronal density in the frontal lobe (22.3 +/- 3.8 x 10(3)/mm(3)) of familial FTDU in comparison to aged controls (33.1 +/- 1.7 x 10(3) per mm(3), P < 0.05). An estimate of the relative numbers of neurons was calculated by multiplying the numerical density by the cortical thickness, which showed a striking loss of neurons of 56% in the frontal lobe, 52% loss in the temporal lobe, and a 49% loss in the parietal lobe of familial FTDU when compared to controls. This study shows that familial FTDU has profound focal neuronal loss in multiple association areas that relate to the clinical symptoms characteristic of the disease.

  16. Innovation for an Inclusive Future

    NASA Astrophysics Data System (ADS)

    Springett, Mark; Rice, Mark; Carmichael, Alex; Griffiths, Richard

    This workshop will focus on setting the agenda for research, practice and policy in support of inclusive design for third generation computer-based products. The next generation of technology represents an unprecedented opportunity to improve the quality of life for groups of users who have previously faced exclusion, such as those with impairments and older citizens. At the same time it risks creating a greater digital divide and further exclusion. How we approach design for this new generation will determine whether or not the third wave will provide positive advances towards an inclusive digital world. We therefore need to put forward both a rationale for inclusive design and provide pointers towards technical development and design practice in support of inclusion. It is our belief that there is not only a strong moral case for design for inclusion but also significant commercial incentive, which may be key to persuading influential players to focus on inclusion. Therefore one of our key objectives is to describe and promote the advantages of designing ‘in from the edges’ of the user population rather than designing for a notional ‘average’ user.

    Renal pigmentation due to the administration of exogenous compounds is an uncommon finding in most species. This report describes renal pigmentation and intranuclear inclusions of the proximal convoluted tubules due to chronic bismuth administration in a rhesus macaque. An 11 year old Indian-origin rhesus macaque with a medical history of chronic intermittent vomiting had been treated with bismuth subsalicylate (BSS), famotidine, and omeprazole singly or in combination over the course of 8 years. At necropsy, the renal cortices were diffusely dark green to black. Light and electron microscopy revealed intranuclear inclusions within the majority of renal proximal tubular epithelial cells. These inclusions appeared magenta to brown when stained with hematoxylin and eosin (H&E) and were negative by the Ziehl-Neelsen acid fast stain. Elemental analysis performed on frozen kidney measured bismuth levels to be markedly elevated at 110.6 ppm, approximately 500-1000 times acceptable limits. To our knowledge this is the first report of renal bismuth deposition in a rhesus macaque resulting in renal pigmentation and intranuclear inclusions. PMID:24990482

    2014-08-01

    A new approach to describing neutron spectra of deuteron-induced reactions in the Monte Carlo simulation for particle transport has been developed by combining the Intra-Nuclear Cascade of Liège (INCL) and the Distorted Wave Born Approximation (DWBA) calculation. We incorporated this combined method into the Particle and Heavy Ion Transport code System (PHITS) and applied it to estimate (d,xn) spectra on natLi, 9Be, and natC targets at incident energies ranging from 10 to 40 MeV. Double differential cross sections obtained by INCL and DWBA successfully reproduced broad peaks and discrete peaks, respectively, at the same energies as those observed in experimental data. Furthermore, an excellent agreement was observed between experimental data and PHITS-derived results using the combined method in thick target neutron yields over a wide range of neutron emission angles in the reactions. We also applied the new method to estimate (d,xp) spectra in the reactions, and discussed the validity for the proton emission spectra.

    2008-02-20

    Bulk chemical and oxygen, magnesium and silicon isotopic compositions were measured for each of 17 Types A and B refractory inclusions from CV3 chondrites. After bulk chemical compositions were corrected for non-representative sampling in the laboratory, the Mg and Si isotopic compositions of each inclusion were used to calculate its original chemical composition assuming that the heavy-isotope enrichments of these elements are due to Rayleigh fractionation that accompanied their evaporation from CMAS liquids. The resulting pre-evaporation chemical compositions are consistent with those predicted by equilibrium thermodynamic calculations for high-temperature nebular condensates but only if different inclusions condensed from nebular regions that ranged in total pressure from 10{sup -6} to 10{sup -1} bar, regardless of whether they formed in a system of solar composition or in one enriched in OC dust relative to gas by a factor of ten relative to solar composition. This is similar to the range of total pressures predicted by dynamic models of the solar nebula for regions whose temperatures are in the range of silicate condensation temperatures. Alternatively, if departure from equilibrium condensation and/or non-representative sampling of condensates in the nebula occurred, the inferred range of total pressure could be smaller. Simple kinetic modeling of evaporation successfully reproduces observed chemical compositions of most inclusions from their inferred pre-evaporation compositions, suggesting that closed-system isotopic exchange processes did not have a significant effect on their isotopic compositions. Comparison of pre-evaporation compositions with observed ones indicates that 80% of the enrichment in refractory CaO + Al{sub 2}O{sub 3} relative to more volatile MgO + SiO{sub 2} is due to initial condensation and 20% due to subsequent evaporation for both Type A and Type B inclusions.

    Oculopharyngeal muscular dystrophy (OPMD) is an adult-onset disease caused by expanded (GCN)12-17 stretches encoding the N-terminal polyalanine domain of the poly(A) binding protein nuclear 1 (PABPN1). OPMD is characterized by intranuclear inclusions (INIs) in skeletal muscle fibers, which contain PABPN1, molecular chaperones, ubiquitin, proteasome subunits, and poly(A)-mRNA. We describe an adenoviral model of PABPN1 expression that produces INIs in most cells. Microarray analysis revealed that PABPN1 overexpression reproducibly changed the expression of 202 genes. Sixty percent of upregulated genes encode nuclear proteins, including many RNA and DNA binding proteins. Immunofluorescence microscopy revealed that all tested nuclear proteins encoded by eight upregulated genes colocalize with PABPN1 within the INIs: CUGBP1, SFRS3, FKBP1A, HMG2, HNRPA1, PRC1, S100P, and HSP70. In addition, CUGBP1, SFRS3, and FKBP1A were also found in OPMD muscle INIs. This study demonstrates that a large number of nuclear proteins are sequestered in OPMD INIs, which may compromise cellular function.

    2009-07-01

    Social interaction and development of friendships between children with and without a disability are often proposed as potential outcomes of inclusive education. Physical activity specialists assert that exercise and sport environments may be conducive to social and friendship outcomes. This study investigated friendship in inclusive physical education from the perspective of students with (n = 8) and without (n = 8) physical disabilities. All participants attended a reversely integrated school and were interviewed using a semistructured, open-ended format. An adapted version of Weiss, Smith, and Theeboom's (1996) interview guide exploring perceptions of peer relationships in the sport domain was used. Four conceptual categories emerged from the analysis: development of friendship, best friend, preferred physical activities and outcomes, and dealing with disability. The results demonstrated the key characteristics of best friends and the influential role they play.

  20. Melt inclusions in Luna 24 soil fragments

    NASA Technical Reports Server (NTRS)

    Roedder, W.; Weiblen, P. W.

    1978-01-01

    Optical examinations of 28 slides of Luna 24 soil fragments revealed melt inclusions in grains of olivine, plagioclase, spinel, and ilmenite as well as interstitial inclusions. In contrast with Apollo samples, the Luna 24 samples contain sulfide melt inclusions, which indicates that saturation with respect to an iron sulfide melt took place throughout much of the crystallization history, even while olivine was crystallizing. The Luna 24 silicate-melt inclusions have recorded a more extensive differentiation toward higher iron magmas than have the Apollo inclusions, but they have also recorded some inexplicably low aluminum values.

  1. Antiferromagnetic inclusions in lunar glass

    Thorpe, A.N.; Senftle, F.E.; Briggs, Charles; Alexander, Corrine

    1974-01-01

    The magnetic susceptibility of 11 glass spherules from the Apollo 15, 16, and 17 fines and two specimens of a relatively large glass spherical shell were studied as a function of temperature from room temperature to liquid helium temperatures. All but one specimen showed the presence of antiferromagnetic inclusions. Closely spaced temperature measurements of the magnetic susceptibility below 77 K on five of the specimens showed antiferromagnetic temperature transitions (Ne??el transitions). With the exception of ilmenite in one specimen, these transitions did not correspond to any transitions in known antiferromagnetic compounds. ?? 1974.

  2. The crack-inclusion interaction problem

    NASA Technical Reports Server (NTRS)

    Xue-Hui, L.; Erdogan, F.

    1984-01-01

    The general plane elastostatic problem of interaction between a crack and an inclusion is considered. The Green's functions for a pair of dislocations and a pair of concentrated body forces are used to generate the crack and the inclusion. Integral equations are obtained for a line crack and an elastic line inclusion having an arbitrary relative orientation and size. The nature of stress singularity around the end points of rigid and elastic inclusions is described and three special cases of this intersection problem are studied. The problem is solved for an arbitrary uniform stress state away from the crack-inclusion region. The nonintersecting crack-inclusion problem is considered for various relative size, orientation, and stiffness parameters, and the stress intensity factors at the ends of the inclusion and the crack are calculated. For the crack-inclusion intersection case, special stress intensity factors are defined and are calculated for various values of the parameters defining the relative size and orientation of the crack and the inclusion and the stiffness of the inclusion.

  3. Cyclodextrin Inclusion Polymers Forming Hydrogels

    NASA Astrophysics Data System (ADS)

    Li, Jun

    This chapter reviews the advances in the developments of supramolecular hydrogels based on the polypseudorotaxanes and polyrotaxanes formed by inclusion complexes of cyclodextrins threading onto polymer chains. Both physical and chemical supramolecular hydrogels of many different types are discussed with respect to their preparation, structure, property, and gelation mechanism. A large number of physical supramolecular hydrogels were formed induced by self-assembly of densely packed cyclodextrin rings threaded on polymer or copolymer chains acting as physical crosslinking points. The thermo-reversible and thixotropic properties of these physical supramolecular hydrogels have inspired their applications as injectable drug delivery systems. Chemical supramolecular hydrogels synthesized from polypseudorotaxanes and polyrotaxanes were based on the chemical crosslinking of either the cyclodextrin molecules or the included polymer chains. The chemical supramolecular hydrogels were often made biodegradable through incorporation of hydrolyzable threading polymers, end caps, or crosslinkers, for their potential applications as biomaterials.

  4. Inclusion bodies: formation and utilisation.

    PubMed

    Fahnert, Beatrix; Lilie, Hauke; Neubauer, Peter

    2004-01-01

    The efficient in vivo folding of many heterologous proteins is a major bottleneck of high level production in bacterial hosts and simple optimisation protocols have not been available yet. Therefore, inclusion body (IB) based processes play a major role as a potential strategy for the production of complex recombinant proteins. These processes combine the advantages of a high accumulation of the target protein in well-characterised bacteria such as Escherichia coli, efficient strategies for IB isolation, purification and in vitro protein refolding without the need of complicated coexpression systems. Recent advances in the molecular physiology of IB formation and resolubilisation allow straight-forward optimisation of fermentation processes to obtain a high-quality product. In addition, simple strategies have been developed to optimise the purification and renaturation of disulfide bond containing proteins making a fast transfer of such processes into the industrial production scale realistic.

  5. Inclusion bodies: not that bad…

    Ramón, Ana; Señorale-Pose, Mario; Marín, Mónica

    2014-01-01

    The formation of inclusion bodies (IBs) constitute a frequent event during the production of heterologous proteins in bacterial hosts. Although the mechanisms leading to their formation are not completely understood, empirical data have been exploited trying to predict the aggregation propensity of specific proteins while a great number of strategies have been developed to avoid the generation of IBs. However, in many cases, the formation of such aggregates can be considered an advantage for basic research as for protein production. In this review, we focus on this positive side of IBs formation in bacteria. We present a compilation on recent advances on the understanding of IBs formation and their utilization as a model to understand protein aggregation and to explore strategies to control this process. We include recent information about their composition and structure, their use as an attractive approach to produce low cost proteins and other promising applications in Biomedicine. PMID:24592259

  6. Working towards an inclusive curriculum.

    PubMed

    Wren, Y; Parkhouse, J

    1998-01-01

    The move towards an inclusive model of education presents teachers with the difficulty of differentiating the curriculum for children with speech, language and communication impairments. This paper focuses on the 'WiSaLT Curriculum Appendix'-a tool which can be used by teachers and speech and language therapists to help such children access the mainstream curriculum and to promote improvement in their language and communication skills. As well as highlighting potential areas of difficulty within each attainment target for key stage one, the appendix guides users to specific strategies and activities. Thus the speech and language therapist and teacher can identify which attainment targets might prove problematic for any one child and also have access to ideas which can help.

  7. Shock Re-equilibration of Fluid Inclusions

    NASA Technical Reports Server (NTRS)

    Madden, M. E. Elwood; Horz, F.; Bodnar, R. J.

    2004-01-01

    Fluid inclusions (microscopic volumes of fluid trapped within minerals as they precipitate) are extremely common in terrestrial minerals formed under a wide range of geological conditions from surface evaporite deposits to kimberlite pipes. While fluid inclusions in terrestrial rocks are nearly ubiquitous, only a few fluid inclusion-bearing meteorites have been documented. The scarcity of fluid inclusions in meteoritic materials may be a result of (a) the absence of fluids when the mineral was formed on the meteorite parent body or (b) the destruction of fluid inclusions originally contained in meteoritic materials by subsequent shock metamorphism. However, the effects of impact events on pre-existing fluid inclusions trapped in target and projectile rocks has received little study. Fluid inclusions trapped prior to the shock event may be altered (re-equilibrated) or destroyed due to the high pressures, temperatures, and strain rates associated with impact events. By examining the effects of shock deformation on fluid inclusion properties and textures we may be able to better constrain the pressure-temperature path experienced by terrestrial and meteoritic shocked materials and also gain a clearer understanding of why fluid inclusions are rarely found in meteorite samples.

  8. Making the case for inclusive design.

    Waller, Sam; Bradley, Mike; Hosking, Ian; Clarkson, P John

    2015-01-01

    This paper describes the University of Cambridge, Engineering Design Centre's (EDC) case for inclusive design, based on 10 years of research, promotion and knowledge transfer. In summary, inclusive design applies an understanding of customer diversity to inform decisions throughout the development process, in order to better satisfy the needs of more people. Products that are more inclusive can reach a wider market, improve customer satisfaction and drive business success. The rapidly ageing population increases the importance of this approach. The case presented here has helped to convince BT, Nestlé and others to adopt an inclusive approach.

  9. Active intranuclear movement of herpesvirus capsids.

    PubMed

    Forest, Thomas; Barnard, Sandra; Baines, Joel D

    2005-04-01

    Although small molecules diffuse rapidly through the interphase nucleus, recent reports indicate that nuclear diffusion is limited for particles that are larger than 100 nm in diameter. Given the apparent size limits to nuclear diffusion, there is some debate as to whether the movement of large particles should be attributed to diffusion or to active transport. Here, we show that 125 nm-diameter herpes simplex virus 1 (HSV-1) capsids are actively transported within infected nuclei. Movement is directed, temperature- and energy-dependent, sensitive to the putative myosin inhibitor 2,3-butanedione monoxime (BDM) and to actin depolymerization with latrunculin-A, but insensitive to actin depolymerization with cytochalasin-D.

  10. Gassmann-Consistency of Inclusion Models

    NASA Astrophysics Data System (ADS)

    Goebel, M.; Wollner, U.; Dvorkin, J. P.

    2015-12-01

    Mathematical inclusion theories predict the effective elastic properties of a porous medium with idealized-shape inclusions as a function of the elastic moduli of the host matrix and those of the inclusions. These effective elastic properties depend on the volumetric concentration of the inclusions (the porosity of the host frame) and the aspect ratio of an inclusion (the ratio between the thickness and length). Seemingly, these models can solve the problem of fluid substitution and solid substitution: any numbers can be used for the bulk and shear moduli of the inclusions, including zero for empty inclusions (dry rock). In contrast, the most commonly used fluid substitution method is Gassmann's (1951) theory. We explore whether inclusion based fluid substitution is consistent with Gassmann's fluid substitution. We compute the effective bulk and shear moduli of a matrix with dry inclusions and then conduct Gassmann's fluid substitution, comparing these results to those from directly computing the bulk and shear moduli of the same matrix but with the inclusions having the bulk modulus of the fluid. A number of examples employing the differential effective medium (DEM) model and self-consistent (SC) approximation indicate that the wet-rock bulk moduli as predicted by DEM and SC are approximately Gassmann-consistent at high aspect ratio and small porosity. However, at small aspect ratios and high porosity, these inclusion models are not Gassmann-consistent. For all cases, the shear moduli are not Gassmann-consistent at all, meaning that the wet-rock shear modulus as given by DEM or SC is very different from the dry-rock moduli as predicted by the same theories. We quantify the difference between the two methods for a range of porosity and aspect ratio combinations.

  11. Geometric Modeling of Inclusions as Ellipsoids

    NASA Technical Reports Server (NTRS)

    Bonacuse, Peter J.

    2008-01-01

    Nonmetallic inclusions in gas turbine disk alloys can have a significant detrimental impact on fatigue life. Because large inclusions that lead to anomalously low lives occur infrequently, probabilistic approaches can be utilized to avoid the excessively conservative assumption of lifing to a large inclusion in a high stress location. A prerequisite to modeling the impact of inclusions on the fatigue life distribution is a characterization of the inclusion occurrence rate and size distribution. To help facilitate this process, a geometric simulation of the inclusions was devised. To make the simulation problem tractable, the irregularly sized and shaped inclusions were modeled as arbitrarily oriented, three independent dimensioned, ellipsoids. Random orientation of the ellipsoid is accomplished through a series of three orthogonal rotations of axes. In this report, a set of mathematical models for the following parameters are described: the intercepted area of a randomly sectioned ellipsoid, the dimensions and orientation of the intercepted ellipse, the area of a randomly oriented sectioned ellipse, the depth and width of a randomly oriented sectioned ellipse, and the projected area of a randomly oriented ellipsoid. These parameters are necessary to determine an inclusion s potential to develop a propagating fatigue crack. Without these mathematical models, computationally expensive search algorithms would be required to compute these parameters.

  2. Hamiltonian inclusive fitness: a fitter fitness concept

    PubMed Central

    Costa, James T.

    2013-01-01

    In 1963–1964 W. D. Hamilton introduced the concept of inclusive fitness, the only significant elaboration of Darwinian fitness since the nineteenth century. I discuss the origin of the modern fitness concept, providing context for Hamilton's discovery of inclusive fitness in relation to the puzzle of altruism. While fitness conceptually originates with Darwin, the term itself stems from Spencer and crystallized quantitatively in the early twentieth century. Hamiltonian inclusive fitness, with Price's reformulation, provided the solution to Darwin's ‘special difficulty’—the evolution of caste polymorphism and sterility in social insects. Hamilton further explored the roles of inclusive fitness and reciprocation to tackle Darwin's other difficulty, the evolution of human altruism. The heuristically powerful inclusive fitness concept ramified over the past 50 years: the number and diversity of ‘offspring ideas’ that it has engendered render it a fitter fitness concept, one that Darwin would have appreciated.

  3. Crystallographic orientations of olivine inclusions in diamonds

    Milani, S.; Nestola, F.; Angel, R. J.; Nimis, P.; Harris, J. W.

    2016-11-01

    In this work we report for the first time the crystallographic orientations of olivine inclusions trapped in diamonds from the Kaapvaal craton (South Africa) determined by single-crystal X-ray diffraction, and analyze them together with all available data in the literature. The overall data set indicates no preferred orientation of the olivine inclusions with respect to their diamond hosts. However, diamonds containing multiple olivine inclusions sometimes show clusters of olivines with the same orientation in the same diamond host. We conclude that such clusters can only be interpreted as the remnants of single olivine crystals pre-dating the growth of the host diamonds.

  4. Nickel and chromium isotopes in Allende inclusions

    NASA Technical Reports Server (NTRS)

    Birck, J. L.; Lugmair, G. W.

    1988-01-01

    High-precision nickel and chromium isotopic measurements were carried out on nine Allende inclusions. It is found that Ni-62, Ni-64, excesses are present in at least three of the samples. The results suggest that the most likely mechanism for the anomalies is a neutron-rich statistical equilibrium process. An indication of elevated Ni-60 is found in almost every inclusion measured. This effect is thought to be related to the decay of now extinct Fe-60. An upper limit of 1.6 X 10 to the -6th is calculated for the Fe-60/Fe-56 ratio at the time these Allende inclusions crystallized.

  5. Detecting and Correcting Melt Inclusion Modification

    NASA Astrophysics Data System (ADS)

    Cottrell, E.; Kelley, K. A.

    2008-12-01

    Post entrapment diffusive modification of melt inclusions may mute or erase primary signatures. Corrections for post-entrapment crystallization (PEC) and Fe-loss are routinely applied and, because recent experimental studies suggest rapid diffusion of trace components into and out of olivine-hosted inclusions, the ability to discriminate between primary and secondary signatures is now even more critical. Two tools may assist in this endeavor. XANES measurements of Fe3+/ΣFe ratios in undegassed ol-hosted basaltic melt inclusions from global arcs are 16-36% (n=16), significantly higher than the 7-10% commonly assumed, and higher than in MORB or BABB lavas (Kelley and Cottrell, this mtg). The Fe3+/ΣFe ratios indicate melt-host equilibrium, with significantly less PEC or Fe-loss than would have been otherwise assumed. We conclude that Fe2+ diffusion has been minimal; therefore the residence time of these primitive inclusions in an evolved magma must have been short. Fe3+/ΣFe correlates positively with water concentration, but not with CO2 and S concentrations or Mg#. The oxidized nature of arc lavas and melt inclusions may therefore indicate an oxidized source rather than late-stage degassing or fractionation. Trace element concentrations evolve with time if an inclusion is out of equilibrium with its host. The numerical model of Cottrell et al., 2002, makes specific predictions about how suites of melt inclusions evolve, creating a tool to detect post-entrapment modification. Recent laboratory measurements of REE diffusion in olivine greatly diverge (at 1300°C, 1015 vs 1019m2/s). If REE diffusivity is extremely fast, melt inclusion HREE diversity shouldn't survive more than a few years in a magma chamber; but if slow, HREE variance could be preserved for >104 yrs. Model analysis of published suites of ol-hosted inclusions indicates that either REE diffusion is quite slow, or the residence time of melt inclusions at high temperature is very short.

    Gordon, John-Stewart

    2013-01-01

    In this article, I question the general idea that inclusive education--i.e., to teach all students in one class--is a moral human right. The following discussion shows that the widespread view in disability studies that there is a moral human right to inclusive education can be reasonably called into question by virtue of the proposed counter arguments, but without denying that inclusive education is of utmost importance. Practically speaking, the legal human right to inclusive education is of great practical value for impaired students, and for their basic right to be free from discrimination in education, since their concern thereby gains great legal and moral force. But, theoretically speaking, this particular human right lacks an attainable consensus concerning proper moral justification.

  10. Water loss from olivine hosted melt inclusions

    NASA Astrophysics Data System (ADS)

    Chen, Y.; Provost, A.; Schiano, P.; Cluzel, N.

    2009-12-01

    Water content in melt inclusions has long been used as an important index for the water content of the hosting magma. However, many studies have shown that post-entrapment diffusive re-equilibration can affect the water content of melt inclusions. This process must be considered when using melt inclusions to infer water content of the hosting magma. Theoretical model on the diffusive re-equilibration between melt inclusions and external melts showed that the re-equilibration rate depends on the diffusivity of the re-equilibrating species in the host mineral, the partition coefficient of this species between the host mineral and melt, and the geometry of the melt inclusion and host mineral. The water diffusivity in olivine and water partition coefficient between melt and olivine have been measured by recent studies, therefore the diffusive re-equilibration model can be tested by experiments. In this study, we carried out in-situ Fourier transform infrared spectroscopy (FTIR) measurements on the water content of olivine hosted melt inclusions at high temperatures. Initial water content of the melt inclusions is about 4 wt%. A heating stage system is combined with a microscope FTIR and the absorption spectrum through the olivine and melt inclusion is repeatedly measured. Although the absorption band at around 3540 cm-1 has not be calibrated at high temperatures, it is assumed that the absorbance is linearly related to the total water concentration in the melt inclusion, and the relative water content can be inferred. Cautions have been exercised to maintain a consistent measurement spot such that the thickness of the melt inclusion within the beam path did not change significantly during each experiment. Oxygen fugacity in the heating stage is controlled by Zr purified Ar gas to be about 7 logarithm units below the QFM buffer and about 1 logarithm unit above the QIF buffer at 1473 K. Preliminary results showed that at 1430 and 1581 K, the total water content of the

  12. Unusual inclusions found in a national diamond

    Leung, I.S.

    1985-01-01

    Three pale yellow minerals, 100-200 microns in their longest dimension, were extracted from a diamond 2.5 mm in size and examined in an SEM equipped with an X-ray energy-dispersive spectrometer. These inclusions were found to be two grains of garnet and a coesite, all of which contain a microscopic grain of Ti-rich biotite, a small amount of sanidine and a number of other minerals. (1) Garnet-biotite-apatite-rutile-sanidine-(Fe,Ca) melt. Attached to one end of this garnet inclusion is a crystal of biotite (50 x 30 ..mu..m) in which an apatite and a rutile are embedded. A thin lamella of sanidine occurs in the biotite near the garnet boundary. (2) Garnet-biotite-apatite-sanidine-rutile-pyrrhotite-(Fe,Ca,K) phase (unidentified). This garnet inclusion partially encased a biotite crystal while all other phases occur as minute prismatic needles or irregular and globular masses on the inclusion surface. (3) Coesite-biotite-sanidine-calcite. They are considered primary phases because the diamond host contains neither internal nor external fractures. Garnet, coesite, biotite and apatite are syngenetic inclusions in this diamond based on their relatively large sizes and their intergrown relationships. All other phases may also be primary or derived from biotite which, in the presence of sulfur, may produce phlogopite + sanidine + pyrrhotite + rutile. The droplets of melt and thin lamella of sanidine in inclusion (1) seem to be products of incongruent melting of biotite during the emplacement of kimberlite.

  13. Do Melt Inclusions Answer Big Questions?

    NASA Astrophysics Data System (ADS)

    Hofmann, A. W.; Sobolev, A. V.

    2009-12-01

    In a pioneering paper, Sobolev and Shimizu (1993) demonstrated the existence of ultra-depleted melt inclusions in olivine phenocrysts in MORB. They interpreted these as evidence for the preservation of parental melts formed by progressive near-fractional melting. Subsequently many cases have been described where melt inclusions from single basalt samples display enormous chemical and isotopic heterogeneity. The interpretation of these observations hinges critically on whether such melt inclusions can faithfully preserve primary or parental melt composition. If they do, melt inclusion data can truly answer big questions from small-scale observations. If they do not, they answer rather small questions. Favoring the second possibility, Danyushevsky et al. (2004) have suggested that much of the observed variability of highly incompatible trace elements in melt inclusions “may not represent geologically significant melts, but instead reflect localized, grain-scale reaction processes within the magmatic plumbing system.” We disagree and show that this mechanism cannot, for example, explain isotopic heterogeneity measured in several suites of melt inclusions, nor does it not account for the presence of ultra-depleted melts and "ghost" plagioclase signatures in other inclusions. More recently, Spandler et al. (2007) have suggested on the basis of experimental evidence that diffusion rates for REE in olivine are so rapid that parental melt compositions in melt inclusions are rapidly falsified by diffusional exchange with (evolved) host lava. We show that the very fact that extreme chemical and isotopic heterogeneities are routinely preserved in melt inclusions demonstrates that this conclusion is unwarranted, either because residence times of the olivine phenocrysts are much shorter than assumed by Spandler et al. or because the high experimental diffusion rates are caused by an unknown experimental artifact. Although there is no obvious flaw in design and execution of

  14. Endomorphisms on half-sided modular inclusions

    SciTech Connect

    Svegstrup, Rolf Dyre

    2006-12-15

    In algebraic quantum field theory we consider nets of von Neumann algebras indexed over regions of the space time. Wiesbrock [''Conformal quantum field theory and half-sided modular inclusions of von Neumann algebras,'' Commun. Math. Phys. 158, 537-543 (1993)] has shown that strongly additive nets of von Neumann algebras on the circle are in correspondence with standard half-sided modular inclusions. We show that a finite index endomorphism on a half-sided modular inclusion extends to a finite index endomorphism on the corresponding net of von Neumann algebras on the circle. Moreover, we present another approach to encoding endomorphisms on nets of von Neumann algebras on the circle into half-sided modular inclusions. There is a natural way to associate a weight to a Moebius covariant endomorphism. The properties of this weight have been studied by Bertozzini et al. [''Covariant sectors with infinite dimension and positivity of the energy,'' Commun. Math. Phys. 193, 471-492 (1998)]. In this paper we show the converse, namely, how to associate a Moebius covariant endomorphism to a given weight under certain assumptions, thus obtaining a correspondence between a class of weights on a half-sided modular inclusion and a subclass of the Moebius covariant endomorphisms on the associated net of von Neumann algebras. This allows us to treat Moebius covariant endomorphisms in terms of weights on half-sided modular inclusions. As our aim is to provide a framework for treating endomorphisms on nets of von Neumann algebras in terms of the apparently simpler objects of weights on half-sided modular inclusions, we lastly give some basic results for manipulations with such weights.

  15. Inclusion polymerization of isoprene in deoxycholic acid

    NASA Astrophysics Data System (ADS)

    Cataldo, Franco; Ragni, Pietro; Rosati, Aldo; Ursini, Ornella

    2009-05-01

    The radiation-induced polymerization of isoprene was made on its inclusion (or clathrate) complex with deoxycholic acid (DOCA) at 150 and 300 kGy. The microstructure of the resulting polyisoprene (PIP) was studied by FTIR spectroscopy and found fully comparable to that of PIP prepared by emulsion polymerization by a free radical initiator. Thus, the 1,4-trans content was found to be 48% and that of 1,4-cis units was 28% of the polymer structure; the remaining are being 1,2 and 3,4 units. The PIP irregular microstructure was justified in terms of monomer dynamics inside the DOCA channels. PIP from inclusion polymerization is fully amorphous as studied by differential thermal analysis (DTA) in comparison to an authentic sample of trans-1,4-polyisoprene, which instead has a crystalline melting point of 71.5 °C. The inclusion complex of PIP with DOCA (PIP@DOCA) shows a DTA melting point of 194.4 °C, 12.4 °C higher than the melting point of pure DOCA. PIP isolated from inclusion polymerization from DOCA and its complex PIP@DOCA was studied also by thermogravimetry (TGA) and differential thermogravimetry (DTG). Isoprene does not form inclusion complexes with urea and thiourea. When irradiated with these two compounds it produces an oily PIP oligomer whose microstructure was found by FTIR spectroscopy analogous to that of PIP prepared by emulsion polymerization by a free radical initiator.

  12. Inclusive cultural empathy for successful global leadership.

    PubMed

    Pedersen, Paul B; Pope, Mark

    2010-11-01

    Empathy is reported in the research literature as a necessary factor in counseling and psychotherapy, but psychologists have historically interpreted empathy through an exclusively individual focus. Most of the research on empathy has been predicated on a definition of empathy as occurring when one person vicariously experiences the feelings, perceptions, and thoughts of another. In Western cultures, the study of empathy focuses exclusively on the individual, whereas in traditional non-Western cultures, empathy more typically involves an inclusive perspective focusing on the individual and significant others in the societal context. This article explores the reframing of "empathy," based on an individualistic perspective, into "inclusive cultural empathy," based on a more relationship-centered perspective, as an alternative interpretation of the empathic process. Psychologists are both the problem and the solution to this dilemma, and the authors call upon the field to take leadership in applying this "inclusive cultural empathy" model.

    2015-05-01

    In forensic genetics, a mixture of two or more contributors to a DNA profile is often interpreted using the inclusion probabilities theory. In this paper, we present a general formula for estimating the probability of inclusion (PI, also known as the RMNE probability) from a subset of visible alleles when dropouts are possible. This one-locus formula can easily be extended to multiple loci using the cumulative probability of inclusion. We show that an exact formulation requires fixing the number of contributors, hence to slightly modify the classic interpretation of the PI. We discuss the implications of our results for the enduring debate over the use of PI vs likelihood ratio approaches within the context of low template amplifications.

  14. Inclusions in freely suspended smectic films

    NASA Astrophysics Data System (ADS)

    Stannarius, Ralf; Harth, Kirsten

    Smectic liquid crystal phases have a unique property: Like soap solutions, they can form stable freely suspended films. Their aspect ratios can be larger than one million to one. Such films can serve as models for two-dimensional (2D) uids, with or without in-plane anisotropy. Solid or liquid inclusions trapped in these films by capillary forces can move in the film plane and interact with other inclusions, with film thickness gradients or the film boundaries, and even with the local orientation field. We describe preparation techniques to incorporate particles or droplets in thin smectic films, and optical observation methods. Several aspects make inclusions in freely suspended films interesting research objects: They provide rich information on capillary forces as well as surface and interfacial tensions, they can serve as platforms for hydrodynamic studies in 2D, and they may help to understand coalescence dynamics at the transition from 2D to 3D...

    We report on an unusual pathological finding of astrocytes, observed in the brain of a 16-year-old African-American male with severe intellectual disability and spastic quadriplegia. The brain showed bilateral pericentral, perisylvian polymicrogyria and pachygyria, in conjunction with a large number of hypertrophic astrocytes with eosinophilic granular cytoplasmic inclusions. The astrocytic abnormality was more severe in the dysgenetic area but present throughout the cerebral cortex. Astrocytic inclusions stained with acid fuchsin, azocarmine and Holzer's stain, and were immunoreactive for GFAP, S-100, and ubiquitin, but not for αB-crystallin, filamin, vimentin, nestin, tau or α-synuclein. Based on the case and a review of the literature, the authors postulate that these astrocytic inclusions in the cerebral cortex reflect abnormalities in radial glial developmental processes, such as migration, differentiation, or glial-neuronal interaction function during neuronal migration.

  16. History of Inclusive Design in the UK.

    PubMed

    John Clarkson, P; Coleman, Roger

    2015-01-01

    The UK Design Council describes Inclusive Design as neither a new genre of design, nor a separate specialism, but as a general approach to designing in which designers ensure that their products and services address the needs of the widest possible audience, irrespective of age or ability. Inclusive Design (also known [in Europe] as Design for All and as Universal Design in the USA) is in essence the inverse of earlier approaches to designing for disabled and elderly people as a sub-set of the population, and an integral part of a more recent international trend towards the integration of older and disabled people in the mainstream of society. This paper describes the development of Inclusive Design in the UK, from its early beginnings, through its subsequent adoption as a topic of academic research, leading to its recent emergence embodied as a framework and toolkit for design.

    2009-09-01

    We report STAR's preliminary measurement of the inclusive jet longitudinal spin asymmetry ALL using data from the RHIC 2006 run. The 2006 data set was taken with 200 GeV polarized proton-proton collisions and represents 4.7 pb-1 of data. Typical beam polarizations were ~ 55 - 60%. The data are compared with theoretical calculations of ALL based on various GRSV models of the polarized parton distribution functions in the nucleon. Previous STAR inclusive jet ALL and cross section measurements are also presented, as is a discussion of constraints these data place on the allowed theoretical models.

  19. Deformation initiation and localization around inclusions

    NASA Astrophysics Data System (ADS)

    Morales, Luiz F. G.; Rybacki, Erik; Dresen, Georg

    2013-04-01

    Deformation localization along narrow zones of variable scales is a common feature in orogenic belts. Although there are a number of studies that focus on the evolution of brittle fault zones, little is known about the initiation and localization of ductile shear zones. To study the nucleation and evolution of high temperature shear zones, we performed shear experiments in marbles containing structural heterogeneities and analyzed the deformation microstructures and the resulting crystallographic orientation. Cylindrical samples of coarse-grained Carrara marble containing one or two 1 mm thin artificially prepared sheets of fine-grained Solnhofen limestone were deformed in a Paterson-type gas deformation apparatus at 900 ° C temperature and confining pressures of 300 and 400 MPa. Three samples were deformed in axial compression at a bulk strain rate of 8x10-5s-1to axial strains between 0.02 and 0.21 and 15 samples were twisted in torsion at a bulk shear strain rate of 2x10-4s-1to shear strains between 0.01 and 3.74. At low strains, intense twinning of calcite is observed in the calcite grains of Carrara marble near the inclusion. The distance from the tip of the inclusion in which twinning is observed increases with increasing strain. Orientation of the twin planes may vary from parallel to normal to the tip of the inclusion, and with increasing strain there is a tendency of development of "twin conjugates". Together with twinning, subgrain boundaries are observed in this region, possibly followed by initial grain size reduction. In these experiments, strain is localized into narrow bands, as revealed by misorientation maps showing the degree of internal lattice distortion of individual calcite crystals around the tip of the inclusion, reaching values from 3 to 10° , depending on the strain. Internal misorientation of grains increases with decreasing distance to the inclusion. Strain is localized into narrow, long bands extending several mm into the matrix. The

  2. Solid inclusion thermobarometry under fire: Heating experiments on encapsulated quartz inclusions in garnet

    NASA Astrophysics Data System (ADS)

    Ashley, Kyle T.; Steele-MacInnis, Matthew; Bodnar, Robert J.; Darling, Robert S.

    2016-04-01

    Internal pressures of mineral inclusions (Pincl) result from differences in elastic properties of the inclusion mineral and its host mineral. Recent studies utilize pressure-sensitive Raman spectroscopic waveshifts to determine the retained Pincl and apply elastic theory to estimate pressure (or temperature) conditions of entrapment. Quartz inclusions are commonly utilized because quartz is a "soft," compressible mineral that is ubiquitous as an inclusion phase in continental metamorphic rocks. Garnet is a commonly used host because it is rigid and isotropic. Quartz inclusions trapped in garnet at high-P, low-T conditions will retain high Pincl; whereas those trapped at low-P, high-T conditions yield negative waveshifts equating to "negative" pressure, or net tensile stress on the inclusion. While Pincl can be accurately calculated from Raman data, barometry relies also upon the quality of the elastic model, which fundamentally depends on the quality of the P -V -T equations of state (EOS) applied. For quartz, EOS modeling is challenging due to the spontaneous strain that develops close to the lambda transition. In this study we conduct heating experiments on quartz inclusions in garnet from natural samples to assess the response of inclusion pressure to varying temperature (at ambient external pressure), and to evaluate predictions based on commonly applied EOS. Experiments were conducted on two quartz standards (a Herkimer "diamond" and Brazillian quartz) and four completely encapsulated inclusions of quartz in garnet from three tectonically diverse terranes, including: (i) a dilated quartz inclusion (Pincl = -4.3 kbar) from Port Leyden, Adirondack Mountains, New York, (ii) a Barrovian-sequence quartz inclusion from northern Scotland (Pincl = 3.1 kbar), and (iii) two high-pressure (blueschist) quartz inclusions from Sifnos, Greece (Pincl = 7.7 and 8.9 kbar). Standards were heated in 25 ° C increments with smaller increments near the lambda transition. Quartz

  3. Effect of inclusions' distribution on microwave absorbing properties of composites

    2013-03-01

    Effect of inclusions' spatial distributions on the permeability and permittivity of composites is studied using the generalized Maxwell-Garnett equations. The result indicates that inclusions' orientation distribution can increase the longitudinal electromagnetic parameters. For inclusions' random and orientation distribution, single and three-layer absorbers are designed and optimized using genetic algorithm. The result shows that under a given absorbing requirement, absorber with inclusions' orientation distribution is lighter and thinner than absorber with inclusions' random distribution.

  4. When social inclusion is not enough: Implicit expectations of extreme inclusion in borderline personality disorder.

    2015-10-01

    Increasing evidence suggests that individuals with borderline personality disorder (BPD) might feel rejected even when socially included by others. A psychological mechanism accounting for this response bias could be that objective social inclusion violates BPD patients' underlying implicit needs of "extreme" inclusion. Thus, this study investigated whether, during interpersonal exchanges, BPD patients report more rejection-related negative emotions and less feelings of social connection than controls unless they are faced with conditions of extreme social inclusion. Sixty-one BPD patients and 61 healthy controls completed a modified Cyberball paradigm. They were randomly assigned to a condition of ostracism, social inclusion, or overinclusion (a proxy for extreme social inclusion). They then rated their emotional states and feelings of social connection immediately and 20 min after the game. BPD patients reported greater levels of negative emotions than controls in the ostracism and the inclusion conditions, but not when overincluded. Furthermore, only for BPD participants was overinclusion associated with experiencing less negative emotions than the ostracism condition. However, BPD patients reported lower feelings of social connection than controls in any experimental situation. Thus, in BPD, a laboratory condition of "overinclusion" is associated with a reduction of negative emotions to levels comparable to those of control participants, but not with similar degrees of social connection. These results suggest that for BPD patients, even "including contexts" activate feelings of rejection. Their implicit expectations of idealized interpersonal inclusion may nullify the opportunity of experiencing "real" social connection and explain their distorted subjective experiences of rejection.

  11. Paleotemperatures preserved in fluid inclusions in halite

    Roberts, S.M.; Spencer, R.J.

    1995-10-01

    A variety of paleoclimate proxy records allow determination of relative warming or cooling. However, if we are to understand climate change, quantification of past temperature fluctuations is essential. Our research indicates that fluid inclusions in halite can yield homogenization temperatures that record surface brine temperatures at the time of halite precipitation. To avoid problems with stretching, leaking, and initial trapping of air, samples with primary, single-phase (liquid) fluid inclusions are chilled in a freezer to nucleate vapor bubbles. We tested the reliability of this method of obtaining fluid-inclusion homogenization temperatures using modern salts precipitated at Badwater Basin, Death Valley, California. Homogenization temperatures correlate well with measured brine temperatures. The same method is applied to fluid inclusions in Pleistocene halite from a core taken at the same location in Death Valley. Results are at several scales, recording diurnal temperature variations, seasonal temperature fluctuations, and longer-term warming and cooling events that correlate with major changes in the sedimentary environment related to climate. This technique is uniquely instrumental for paleoclimate studies because it offers actual, not just proxy, paleotemperature data. 27 refs., 17 figs.

  10. Nonlinear elastic inclusions in isotropic solids

    PubMed Central

    Yavari, Arash; Goriely, Alain

    2013-01-01

    We introduce a geometric framework to calculate the residual stress fields and deformations of nonlinear solids with inclusions and eigenstrains. Inclusions are regions in a body with different reference configurations from the body itself and can be described by distributed eigenstrains. Geometrically, the eigenstrains define a Riemannian 3-manifold in which the body is stress-free by construction. The problem of residual stress calculation is then reduced to finding a mapping from the Riemannian material manifold to the ambient Euclidean space. Using this construction, we find the residual stress fields of three model systems with spherical and cylindrical symmetries in both incompressible and compressible isotropic elastic solids. In particular, we consider a finite spherical ball with a spherical inclusion with uniform pure dilatational eigenstrain and we show that the stress in the inclusion is uniform and hydrostatic. We also show how singularities in the stress distribution emerge as a consequence of a mismatch between radial and circumferential eigenstrains at the centre of a sphere or the axis of a cylinder.

    Häßler, Frank; Burgert, Michael; Fegert, Jörg Michael; Chodan, Wencke

    2015-07-01

    The term inclusion (=admittance, involvement) is used almost synonymously for the concept of the joint schooling of children with and without intellectual disabilities, language disabilities, physical handicaps, or mental disorders. This article addresses the current state of inclusion in Germany as well as the international situation, such as the Salamanca Declaration of the UNESCO, the «Individuals with Disabilities Act» (IDEA) in the United States as well as European developments, particularly in Great Britain, Austria, and Russia. Even though, from a political perspective, the decision in favor of inclusion seems irreversible, there appears to be a lack an agreement on the modality and timeframe. Thus, the average percentage of students with special education needs in Germany amounts to only 28.2%. The reasons behind this situation are presently being analyzed and discussed. A question of key importance concerns the benefit for the persons concerned, since that should be the measure of the success of inclusion. This question will most likely be validly answered only for individual subgroups of disabilities. This field still requires extensive research.

  14. Numerical Simulations of Inclusion Behavior in Gas-Stirred Ladles

    NASA Astrophysics Data System (ADS)

    Lou, Wentao; Zhu, Miaoyong

    2013-06-01

    A computation fluid dynamics-population balance model (CFD-PBM) coupled model has been proposed to investigate the bubbly plume flow and inclusion behavior including growth, size distribution, and removal in gas-stirred ladles, and some new and important phenomena and mechanisms were presented. For the bubbly plume flow, a modified k- ɛ model with extra source terms to account for the bubble-induced turbulence was adopted to model the turbulence, and the bubble turbulent dispersion force was taken into account to predict gas volume fraction distribution in the turbulent gas-stirred system. For inclusion behavior, the phenomena of inclusions turbulent random motion, bubbles wake, and slag eye forming on the molten steel surface were considered. In addition, the multiple mechanisms both that promote inclusion growth due to inclusion-inclusion collision caused by turbulent random motion, shear rate in turbulent eddy, and difference inclusion Stokes velocities, and the mechanisms that promote inclusion removal due to bubble-inclusion turbulence random collision, bubble-inclusion turbulent shear collision, bubble-inclusion buoyancy collision, inclusion own floatation near slag-metal interface, bubble wake capture, and wall adhesion were investigated. The importance of different mechanisms and total inclusion removal ratio under different conditions, and the distribution of inclusion number densities in ladle, were discussed and clarified. The results show that at a low gas flow rate, the inclusion growth is mainly attributed to both turbulent shear collision and Stokes collision, which is notably affected by the Stokes collision efficiency, and the inclusion removal is mainly attributed to the bubble-inclusion buoyancy collision and inclusion own floatation near slag-metal interface. At a higher gas flow rate, the inclusions appear as turbulence random motion in bubbly plume zone, and both the inclusion-inclusion and inclusion-bubble turbulent random collisions become

    USGS Publications Warehouse

    Burruss, R.C.

    1987-01-01

    Calculations based on the observed behaviour of inclusions in fluorite under external confining P allows prediction of the T and depths of burial necessary to initiate re-equilibration of aqueous inclusions in the common size range 40-4 mu m. Heating of 20-60oC over the initial trapping T may cause errors of 10-20oC in the homogenization T. This suggests that re-equilibration may cause aqueous inclusions in carbonates to yield a poor record of their low-T history, but a useful record of the maximum T experienced by the host rock. Previous work suggests that inclusions containing petroleum fluids will be less susceptible to re-equilibration.This and the following six abstracts represent papers presented at a joint meeting of the Applied Mineralogy Group of the Mineralogical Society and the Petroleum Group of the Geological Society held in Newcastle upon Tyne in April 1986.-R.A.H.

    NASA Technical Reports Server (NTRS)

    Xue-Hui, L.; Erdogan, F.

    1985-01-01

    With the application to weld defects in mind, the interaction problem between a planar-crack and a flat inclusion in an elastic solid is considered. The elastic inclusion is assumed to be sufficiently thin so that the thickness distribution of the stresses in the inclusion may be neglected. The problem is reduced to a system of four integral equations having Cauchy-type dominant kernels. The stress intensity factors are calculated and tabulated for various crack-inclusion geometries and the inclusion to matrix modulus ratios, and for general homogeneous loadiong conditions away from the crack-inclusion region.

    1987-01-01

    Epizootic mortality occurred in Laysan albatross (Diomedea immutabilis) fledgings at Midway Atoll in 1983. Heavy metal toxicity from ingestion of weathered paint chips was one of the causes. Sick albatrosses were unable to retract their wings, causing a 'droop-wing' appearance. Five normal and 12 droop-winged fledglings were captured, killed, and examined. Paint chips found in the proventriculus of the affected fledglings contained up to 144,000 ppm lead. Blood, liver, and kidney concentrations of lead in affected birds were higher than in normal fledglings, and acid-fast intranuclear inclusion bodies were present in the kidneys. Degenerative lesions were present in the myelin of some brachial nerves. Weathered paint samples collected from 12 buildings contained up to 247,250 ppm lead and 101 ppm mercury. Lead poisoning was diagnosed in 10 of the droop-winged albatrosses and was one of the causes of morbidity. Mercury toxicosis and plastic impaction were other possible causes.

    Soon, David SC; Shilton, Hamish; Andrabi, Ali

    2016-01-01

    Mesothelial inclusion cyst is a rare benign tumour that has only 130 cases reported in the literature. Accurate diagnosis and optimal management of this condition remains uncertain. We report a 51-year-old African gentleman, whom presents with abdominal pain and constipation. A computed tomography scan was performed and revealed a large cystic lesion in the right paracolic gutter. The differential diagnosis included appendiceal mucinous neoplasm, cystic tuberculosis and duplication cyst. A laparotomy was performed due to his symptoms and size of the cyst. Macroscopically, the tumour had a size of 25 × 10 × 10 cm and revealed a necrotic lymph node. It was resected en bloc with the appendix and an ileocolic anastomosis performed. Histology revealed a diagnosis of mesothelial inclusion cyst and acute appendicitis. The patient recovered well and had no recurrence at 2-year follow-up. PMID:27994008

    Bacterial inclusion bodies (IBs) are functional, non-toxic amyloids occurring in recombinant bacteria showing analogies with secretory granules of the mammalian endocrine system. The scientific interest in these mesoscale protein aggregates has been historically masked by their status as a hurdle in recombinant protein production. However, progressive understanding of how the cell handles the quality of recombinant polypeptides and the main features of their intriguing molecular organization has stimulated the interest in inclusion bodies and spurred their use in diverse technological fields. The engineering and tailoring of IBs as functional protein particles for materials science and biomedicine is a good example of how formerly undesired bacterial byproducts can be rediscovered as promising functional materials for a broad spectrum of applications.

    Herre, Edward Allen; Wcislo, William T

    2011-03-24

    Arising from M. A. Nowak, C. E. Tarnita & E. O. Wilson 466, 1057-1062 (2010); Nowak et al. reply. Arguably the defining characteristic of the scientific process is its capacity for self-criticism and correction. Nowak et al. challenge proposed connections between relatedness and the evolution of eusociality, suggest instead that defensible nests and "spring-loaded" traits are key, and present alternative modelling approaches. They then dismiss the utility of Hamilton's insight that relatedness has a profound evolutionary effect, formalized in his widely accepted inclusive fitness theory as Hamilton's rule ("Rise and fall of inclusive fitness theory"). However, we believe that Nowak et al. fail to make their case for logical, theoretical and empirical reasons.

  1. Formalizing Darwinism and inclusive fitness theory.

    PubMed

    Grafen, Alan

    2009-11-12

    Inclusive fitness maximization is a basic building block for biological contributions to any theory of the evolution of society. There is a view in mathematical population genetics that nothing is caused to be maximized in the process of natural selection, but this is explained as arising from a misunderstanding about the meaning of fitness maximization. Current theoretical work on inclusive fitness is discussed, with emphasis on the author's 'formal Darwinism project'. Generally, favourable conclusions are drawn about the validity of assuming fitness maximization, but the need for continuing work is emphasized, along with the possibility that substantive exceptions may be uncovered. The formal Darwinism project aims more ambitiously to represent in a formal mathematical framework the central point of Darwin's Origin of Species, that the mechanical processes of inheritance and reproduction can give rise to the appearance of design, and it is a fitting ambition in Darwin's bicentenary year to capture his most profound discovery in the lingua franca of science.

  2. Inclusive science education: learning from Wizard

    NASA Astrophysics Data System (ADS)

    Koomen, Michele Hollingsworth

    2016-06-01

    This case study reports on a student with special education needs in an inclusive seventh grade life science classroom using a framework of disability studies in education. Classroom data collected over 13 weeks consisted of qualitative (student and classroom observations, interviews, student work samples and video-taped classroom teaching and learning record using CETP-COP) methods. Three key findings emerged in the analysis and synthesis of the data: (1) The learning experiences in science for Wizard are marked by a dichotomy straddled between autonomy ["Sometimes I do" (get it)] and dependence ["Sometimes I don't (get it)], (2) the process of learning is fragmented for Wizard because it is underscored by an emerging disciplinary literacy, (3) the nature of the inclusion is fragile and functional. Implications for classroom practices that support students with learning disabilities include focusing on student strengths, intentional use of disciplinary literacy strategies, and opportunities for eliciting student voice in decision making.

  3. Inclusion chemistry in periodic mesoporous hosts

    SciTech Connect

    Moller, K.; Bein, T.

    1998-10-01

    This review provides an overview of different aspects of inclusion chemistry in ordered mesoporous host materials such as MCM-41 or MCM-48 (Mobil codes). A rich field of inclusion chemistry has been explored in this context, including sorption, ion exchange, inhibition followed by reduction, grafting of reactive metal alkoxides, halides, etc., grafting of silane coupling agents (sometimes followed by subsequent reactions), grafting of reactive metal complexes, and polymerization in the channels. Finally, co-condensation of reactive species during the mesopore synthesis is a method to incorporate functionality into the walls of the channel system. Important applications of these modified and functionalized systems are heterogeneous catalysis and photocatalysis involving bulky grated catalysts and/or the conversion of large substrates. Other potential applications include ion exchange and separations, removal of heavy metals, chromatography, stabilization of quantum wires, stabilization of dyes, and polymer composites.

    Most silicate melt inclusions (MI) contain bubbles, whose significance has been alternately calculated, pondered, and ignored, but rarely if ever directly explored. Moore et al. (2015) analyze the bubbles, as well as their host glasses, and conclude that they often hold the preponderance of CO2 in the MI. Their findings entreat future researchers to account for the presence of bubbles in MI when calculating volatile budgets, saturation pressures, and eruptive flux.

    The peritoneal inclusion cyst is a rare, probably congenital, pathology of the mesothelium that develops on coelomatic residues. A case is reported of an unusual location of peritoneal cyst, in which the increase in volume, associated with the patient's concern and the presumed anatomic site of the lesion led to its removal by the laparoscopic route. The type of location and the relative inaccuracy of preoperative imaging are discussed.

    PubMed

    Warnke, Andreas

    2015-07-01

    The Convention on the Rights of Persons with Disabilities became legally binding in Germany in March 2009. “Inclusion” is the major concept–all people with any kind of handicap must have the same rights to full and effective participation and inclusion in society. Preceding inclusion come adjustments in society with regard to ethical, legislative, administrative, conceptual, structural, economical, and thus also to healthcare-political frameworks, in order to make disabilities are as far as possible no longer a handicap in an individual’s everyday life. This review first outlines the present social status influencing the development of children, a child’s welfare, and especially the healthcare of children and adolescents with psychiatric disorders and conditions indicating barriers to inclusion. It focuses on those articles of the UN convention which are relevant with regard to ethical attitude, epidemiology, healthcare framework, diagnostics, therapy, teaching, and research with respect to child and adolescent psychiatry. The analysis points to a significant backlog demand in child psychiatric healthcare, teaching, and research.

    PubMed

    Rippon, Gregory A; Staugaitis, S M; Chin, Steven S M; Goldman, James E; Marder, K

    2005-05-01

    A 42-year-old, left-handed woman first noted impaired dexterity of the dominant hand, soon followed by dysarthria and cognitive decline. Over a 4-year period, she developed severe left-sided apraxia with eventual neglect of the left arm and progressive extrapyramidal signs. Cognitive testing showed progressive executive, visuospatial, fluency, and naming impairment with relative preservation of memory. Single-photon emission computed tomography demonstrated asymmetric right posterior frontal and superior parietal hypoperfusion. The clinical impression was corticobasal degeneration. At autopsy, severe atrophy was seen in the perirolandic and frontal regions. There was marked neuronal loss and gliosis in the posterior frontal and precentral regions and less severe pathology in prefrontal, temporal, and parietal areas. Mild to moderate gliosis and neuronal loss were also seen in the putamen, globus pallidus, subthalamic, and dentate nuclei. Gallyas silver stain revealed numerous inclusions adjacent to oligodendrocyte nuclei in white and gray matter of affected cortical and subcortical regions. The gracile inclusions were wavy, slender, and stained positively with antibodies to ubiquitin and alphaB-crystallin but not to microtubule-associated proteins (tau, MAP1B, MAP2), tubulin, neurofilaments, glial fibrillary acidic protein, or alpha-synuclein. The argyrophilic inclusions identified in this case are distinct from those previously described in neurodegenerative diseases.

    PubMed

    Pfundmair, Michaela; Graupmann, Verena; Du, Hongfei; Frey, Dieter; Aydin, Nilüfer

    2015-03-01

    In the current research, we examined whether re-inclusion (i.e. the change from a previous state of exclusion to a new state of inclusion) was perceived differently by people with individualistic and collectivistic cultural backgrounds. Individualists (German and Austrian participants) but not collectivists (Chinese participants) experienced re-inclusion differently than continued inclusion: While collectivistic participants did not differentiate between both kinds of inclusion, individualistic participants showed reduced fulfilment of their psychological needs under re-inclusion compared to continued inclusion. The results moreover revealed that only participants from individualistic cultures expressed more feelings of exclusion when re-included than when continually included. These exclusionary feelings partially mediated the relationship between the different states of inclusion and basic need fulfilment.

  12. The semi-inclusive jet function in SCET and small radius resummation for inclusive jet production

    NASA Astrophysics Data System (ADS)

    Kang, Zhong-Bo; Ringer, Felix; Vitev, Ivan

    2016-10-01

    We introduce a new kind of jet function: the semi-inclusive jet function J i ( z, ω J , μ), which describes how a parton i is transformed into a jet with a jet radius R and energy fraction z = ω J /ω, with ω J and ω being the large light-cone momentum component of the jet and the corresponding parton i that initiates the jet, respectively. Within the framework of Soft Collinear Effective Theory (SCET) we calculate both J q ( z, ω J , μ) and J g ( z, ω J , μ) to the next-to-leading order (NLO) for cone and anti-kT algorithms. We demonstrate that the renormalization group (RG) equations for J i ( z, ω J , μ) follow exactly the usual DGLAP evolution, which can be used to perform the ln R resummation for inclusive jet cross sections with a small jet radius R. We clarify the difference between our RG equations for J i ( z, ω J , μ) and those for the so-called unmeasured jet functions J i ( ω J , μ), widely used in SCET for exclusive jet production. Finally, we present applications of the new semi-inclusive jet functions to inclusive jet production in e + e - and pp collisions. We demonstrate that single inclusive jet production in these collisions shares the same short-distance hard functions as single inclusive hadron production, with only the fragmentation functions D i h ( z, μ) replaced by J i ( z, ω J , μ). This can facilitate more efficient higher-order analytical computations of jet cross sections. We further match our ln R resummation at both LL R and NLL R to fixed NLO results and present the phenomenological implications for single inclusive jet production at the LHC.

    The contents of Ag, Au, Bi, Cd, Co, Cs, Ga, In, Rb, Sb, Se, Te, Tl, U, and Zn in large chondritic clasts from the Cumbersand Falls aubrite were determined by radiochemical neutron activation analysis, and the results, together with the results of a mineralogical investigation, were compared with respective data obtained for three primitive inclusions from the ALH A78113 aubrite. The results indicated that the clasts from both aubrite sources constitute a single chondritic suite. The analyses data, together with the results of thermoluminescence data for Cumberland Falls chondritic inclusions and achondritic host, indicate that inclusions in Cumberland Falls and in ALH A78113 aubrite represent a primitive chondrite sample suite whose properties were established during primary nebular accretion and condensation over a broad redox range.

    2011-10-01

    SiCa line and SiCaBaFe alloy were injected into liquid pipeline steel at the end of LF refining as calcium treatment, and samples were taken from the ladles, mould, and slabs. Analysis of Ca content and inclusions shows that Ca content in steel decreases obviously in the following process after calcium treatment; the compositions, morphology, and sizes of inclusions also vary much in the production; primary inclusions in the ladles prior to calcium treatment are mainly Al2O3 inclusions, but they turn to fine irregular CaS-CaO-Al2O3 compound inclusions after the treatment, then become fine globular CaO-Al2O3 inclusions in the mould, and finally change to a few larger irregular CaS-CaO-Al2O3 complex inclusions in the slabs. Thermodynamic study reveals that inclusion variations are related with the preferential reactions among Ca, Al2O3, and S and the precipitation of S in CaO-Al2O3 inclusions with high sulfur capacity. New evaluation standards for calcium treatment in high-grade pipeline steel were put forward according to the inclusion variations and requirements of pipeline steel on inclusion controlling, and the calcium process was studied and optimized.

    Inclusion body myositis (IBM) is the most common inflammatory myopathy after 50 years of age. In contrast to polymyositis and dermatomyositis, in which cardiac involvement is relatively common, current evidences indicate that IBM is not associated with cardiac disease. We report the case of a patient with biopsy-proven IBM who developed heart failure and major ventricular arrhythmias secondary to dilated cardiomyopathy few months after the clinical onset of IBM, and in whom no pathophysiologic causes explaining cardiac enlargement and dysfunction were found by laboratory and instrumental investigations. The hypothesis of a pathophysiologic association between the two conditions is discussed.

    MINERνA is a few-GeV neutrino scattering experiment that has been taking data in the NuMI beam line at Fermilab since November 2009. The experiment will provide important inputs, both in support of neutrino oscillation searches and as a pure weak probe of the nuclear medium. For this, MINERvA employs a fine-grained detector, with an eight ton active target region composed of plastic scintillator and a suite of nuclear targets composed of helium, carbon, iron, lead and water placed upstream of the active region. We will describe the current status of the charged current inclusive analysis in plastic scintillator.

    The project objective is to determine the conditions under which the inclusions in liquid steel can act as heterogeneous nucleants for solidification. The experimental approach consisted of measuring the undercooling of a pure iron droplet in contact with different oxides to determine which oxides promote iron solidification by providing a suitable surface for nucleation and which oxides and under which conditions the metal can be deeply undercooled. The conclusions suggest that deep undercoolings are possible at low oxygen content provided the oxygen potential is such that substrate decomposition does not occur. If the oxygen content increases the undercooling decreases.

    A composite dust grain model which simultaneously explains the observed interstellar extinction, polarization, IR emission and the abundance constraints, is required. We present a composite grain model, which is made up of a host silicate oblate spheroid and graphite inclusions. The interstellar extinction curve is evaluated in the spectral region 3.4-0.1 μm using the extinction efficiencies of composite spheroidal grains for three axial ratios. Extinction curves are computed using the discrete dipole approximation (DDA). The model curves are subsequently compared with the average observed interstellar extinction curve and with an extinction curve derived from the IUE catalogue data.

  16. Budding and vesiculation induced by conical membrane inclusions

    NASA Astrophysics Data System (ADS)

    Auth, Thorsten; Gompper, Gerhard

    2009-09-01

    Conical inclusions in a lipid bilayer generate an overall spontaneous curvature of the membrane that depends on concentration and geometry of the inclusions. Examples are integral and attached membrane proteins, viruses, and lipid domains. We propose an analytical model to study budding and vesiculation of the lipid bilayer membrane, which is based on the membrane bending energy and the translational entropy of the inclusions. If the inclusions are placed on a membrane with similar curvature radius, their repulsive membrane-mediated interaction is screened. Therefore, for high inclusion density the inclusions aggregate, induce bud formation, and finally vesiculation. Already with the bending energy alone our model allows the prediction of bud radii. However, in case the inclusions induce a single large vesicle to split into two smaller vesicles, bending energy alone predicts that the smaller vesicles have different sizes whereas the translational entropy favors the formation of equal-sized vesicles. Our results agree well with those of recent computer simulations.

    2003-01-01

    This paper provides an overview of some of the more important developments in fluid-inclusion research and applications in recent years, including fluid-inclusion petrography, PVTX studies, and analytical techniques. In fluid-inclusion petrography, the introduction of the concept of 'fluid-inclusion assemblage' has been a major advance. In PVTX studies, the use of synthetic fluid inclusions and hydrothermal diamond-anvil cells has greatly contributed to the characterization of the phase behaviour of geologically relevant fluid systems. Various analytical methods are being developed and refined rapidly, with the Laser-Raman and LA-ICP-MS techniques being particularly useful for volatile and solute analyses, respectively. Ore deposit research has been and will continue to be the main field of application of fluid inclusions. However, fluid inclusions have been increasingly applied to other fields of earth science, especially in petroleum geology and the study of magmatic and earth interior processes.

    2010-09-01

    Participatory Action Research (PAR) with children and youth is at the intersection of child wellness and social inclusion. Exclusion and marginalization detract from personal and collective health. Inclusion, on the contrary, contributes to wellness. Hence, we should study inclusion and exclusion in the overall context of child wellness. This special issue offers a wealth of methodologies and lessons for fostering inclusion of young people through PAR. In an effort to synthesize my concerns with child wellness, inclusion, and the scholarly work of this special issue, this paper will (a) articulate the values underpinning the philosophy of social inclusion and child wellness, (b) suggest roles and responsibilities for putting these values into action, and (c) integrate the contributions of this special issue into the emerging framework for social inclusion and child wellness.

  19. Distinguishing primary and secondary inclusion assemblages in Jack Hills zircons

    NASA Astrophysics Data System (ADS)

    Bell, Elizabeth A.; Boehnke, Patrick; Hopkins-Wielicki, Michelle D.; Harrison, T. Mark

    2015-10-01

    Detrital igneous zircons from Jack Hills, Western Australia, range in age from ~ 3.0 to nearly 4.4 Ga and contain an inclusion assemblage dominated by quartz and muscovite, cited as evidence of their derivation from peraluminous granitoids. However, some phosphate inclusions in these zircons are known to be secondary from their post-depositional U-Pb ages and manifest mineralization along cracks. We undertook a survey of mineral inclusions in 4.3-3.0 Ga Jack Hills zircons with particular emphasis on their relationship to possible alteration features (e.g., cracks, disturbed internal zonation, and visual turbidity). Mineral inclusions revealed at polished surfaces show variations in modal mineralogy, mostly corresponding to their relationship with cracks. Muscovite is common both on and away from cracks, although the chemistry of muscovite inclusions shows little relationship with other potential alteration features. Inclusions filling cracks (secondary) and inclusions isolated from cracks differ in their modal mineralogy, although both suites are rich in muscovite and quartz. The higher incidence of crack-intersecting inclusions among younger zircons may reflect effects of the (generally larger) inclusion size among younger zircons. Mismatches between the isolated and crack-intersecting populations indicate selective loss of certain phases (e.g., feldspar, apatite) and over-representation of quartz and muscovite along cracks likely due to the effects of larger inclusion size and varying degrees of overpressure following zircon cooling and decompression. Inclusions not associated with cracks in magmatically zoned versus regions with disturbed zoning have similar phase proportions. This indicates only minor inclusion replacement away from cracks (i.e., the isolated assemblage is likely primary). This holds true also for inclusions within visually turbid versus clear volumes of zircon. Phase proportions within the inclusion assemblages differ with age indicating a

    PubMed

    Chakrabarti, Anjan; Dhar, Anup

    2012-12-01

    This paper makes two related contributions. First, the dual economic structure underlying development is shown as producing a distinct conception of other comprising of a devalued third world which is foregrounded and world of the third which is excluded. This dyad of inclusion-exclusion of other is produced in relation to the centers of capitalism and modernism. The category of third world helps to displace the language-experience-logic-ethos of the other a la world of the third such that development works over and transforms world of the third, but via the trope of a devalued third world. We then use this framework to explore the relation of global capitalism with world of the third in the Indian context, a relation that is shown to be two fold. There is on one hand an attempt to dismantle world of the third as part of the development trope of overcoming the third world. On the other, through inclusive development, an attempt is made to directly intervene in the economy of world of the third so as to address the problems of income inequality and social exclusion, again under the trope of uplifting the devalued third world.

  1. Inclusion body myositis: old and new concepts.

    PubMed

    Amato, A A; Barohn, R J

    2009-11-01

    Inclusion body myositis (IBM) is the most common idiopathic inflammatory myopathy occurring in patients over the age of 50 years and probably accounts for about 30% of all inflammatory myopathies. Muscle biopsy characteristically reveals endomysial inflammation, small groups of atrophic fibres, eosinophilic cytoplasmic inclusions and muscle fibres with one or more rimmed vacuoles. However, any given biopsy may lack these histopathological abnormalities; the clinical examination is often the key to diagnosis. Early and often asymmetrical weakness and atrophy of the quadriceps and flexor forearm muscles (ie, wrist and finger flexors) are the clinical hallmarks of IBM. The pathogenesis of IBM is unknown. It may be autoimmune inflammatory myopathy or a primary degenerative myopathy with a secondary inflammatory. A prevailing theory is that there is an overproduction of beta-amyloid precursor protein in muscle fibres that is somehow cleaved into abnormal beta-amyloid, and the accumulation of the latter is somehow toxic to muscle fibres. However, there are many problems with this theory and more work needs to be done. Unfortunately, IBM is generally refractory to therapy. Further research into the pathogenesis, along with both preliminary small pilot trials and larger double blind, placebo controlled efficacy trials, are needed to make progress in our understanding and therapeutic approach for this disorder.

    Purpose People with disabilities often encounter difficulties at the workplace such as exclusion or unfair treatment. Researchers have therefore pointed to the need to focus on behavior that fosters inclusion as well as variables that are antecedents of such 'inclusive behavior'. Therefore the purpose of this study was to research the relationship between prosocial motivation, team inclusive climate and employee inclusive behavior. Method A survey was conducted among a sample of 282 paired employees and colleagues, which were nested in 84 teams. Employees self-rated prosocial motivation and team inclusive climate, their inclusive behavior was assessed by colleagues. Hypotheses were tested using multilevel random coefficient modeling. Results Employees who are prosocially motivated will display more inclusive behavior towards people with disabilities, and this relationship is moderated by team inclusive climate in such a way that the relationship is stronger when the inclusive climate is high. Conclusion This study shows that inclusive organizations, which value a diverse workforce, need to be aware of not only individual employee characteristics, but also team level climate to ensure the smooth integrations of people with disabilities into regular work teams.

    Large and hard inclusions often deteriorate the service performance and reduce the fatigue lifetime of drill rods. In this paper, the main reasons of the rupture of drill rods were analyzed by the examination of their fracture and it is found that the large inclusions were the main reason of breakage of rod drill. The inclusions were high of Ca content or Al2O3 rich. Smaller and better deformability inclusions were obtained by the optimization of refining slag, calcium treatment process and the flow control devices of tundish. Results of industrial experiment after optimization show that total oxygen content of drill rods decreased by more than 50%, macro-inclusions weight fraction decreased from about 4 mg/10 kg to about 0.3 mg/10 kg and the micro-inclusions average size decreased from 6 to 3.6 μm. The average using times of drill rods after optimization were increased by about 60%.

    New data on the study of residual pressure in mineral inclusions in diamonds from kimberlite pipes and placers of Yakutia obtained using Raman Spectroscopy are presented. Calculated values of residual pressure in olivine and coesite inclusions in kimberlite diamonds according to works of Israeli et al [1] and Sobolev et al [2] indicate that the host crystal crystallized at the depth not less than 165 km, at pressure of 4.8-5.0 GPa and temperature T=1200 °C. Comparative analysis of Raman spectra of olivine inclusions in diamonds from placers of Ebelyakh river on inclusions, contained in diamond and then brought to the surface, showed that olivine inclusions are less stressed. The structural orientation of olivine inclusions in diamonds from placers of Ebelyakh river possibly plays a role in these differences of Raman spectra.

    2015-01-01

    Nurse leaders call for a more diverse nursing workforce, but too few address the concept of inclusion as a recruitment and retention strategy or as part of improving the academic learning milieu. This article addresses organizational considerations of diversity and inclusion as part of the agenda established by the Association of American Colleges and Universities for inclusive excellence, building on the idea that academic environments only become excellent when an inclusive climate is reached. Six organizational strategies to inclusion are presented from the authors' experiences, some structural and others behavioral: admissions processes, invisibility, absence of community, promotion and tenure, exclusion, and tokenism. A call for structural and behavioral adaptions within nursing education to advance an inclusive excellence agenda is presented.

    Inclusive electron scattering from nuclei at large x and Q{sup 2} is the result of a reaction mechanism that includes both quasi-elastic scattering from nucleons and deep inelastic scattering from the quark consitituents of the nucleons. Data in this regime can be used to study a wide variety of topics, including the extraction of nuclear momentum distributions, the infiuence of final state interactions and the approach to y-scaling, the strength of nucleon-nucleon correlations, and the approach to x-scaling, to name a few. Selected results from the recent experiment E02-019 at the Thomas Jefferson National Accelerator Facility will be shown and their relevance discussed.

    The conventional educational environment imposes barriers to education for people with disabilities, limiting their rights, which is a non-discriminative education. In turn, hampers their access to other rights and creates huge obstacles to realize their potential and participate effectively in their communities. In this sense Assistive Technology provides alternative solutions, in order to compensate for a lost or diminished ability. Thus the necessary assistance is provided to perform tasks, including those related to education, improving the inclusion. In this paper some researches had been made in the Gabinete de TecnologiaMedica, in the Facultad de Ingenieria of the Universidad Nacional de San Juan in order to solve this problem. The researchers are classified by type of disability; sensory (visual and auditory) or motor. They have been designed, developed and experienced through various prototypes that have given satisfactory results. It had been published in national and international congresses of high relevance.

    Calcium- and aluminum-rich inclusions (CAIs) occur in all classes of chondritic meteorites and contain refractory minerals predicted to be the first condensates from the solar nebula. Near-infrared spectra of CAIs have strong 2-micrometer absorptions, attributed to iron oxide-bearing aluminous spinel. Similar absorptions are present in the telescopic spectra of several asteroids; modeling indicates that these contain approximately 30 +/- 10% CAIs (two to three times that of any meteorite). Survival of these undifferentiated, large (50- to 100-kilometer diameter) CAI-rich bodies suggests that they may have formed before the injection of radiogenic 26Al into the solar system. They have also experienced only modest post-accretionary alteration. Thus, these asteroids have higher concentrations of CAI material, appear less altered, and are more ancient than any known sample in our meteorite collection, making them prime candidates for sample return.

    Inclusion body myositis is a form of inflammatory myopathy. We identified 4 cases of inclusion body myositis showing granuloma formation in muscle tissue and aimed to assess the features of this atypical form of inclusion body myositis. We retrospectively reviewed consecutive patients who satisfied European Neuromuscular Centre IBM Research Diagnostic Criteria 2011. Then, we assessed clinical profiles and pathological findings in patients with inclusion body myositis with granuloma and compared these findings with those of typical inclusion body myositis without granuloma. We identified 15 patients with inclusion body myositis. Four patients showed granuloma formation in muscle tissue in addition to typical pathological features of inclusion body myositis. Granulomas comprised a mixture of inflammatory cells, such as macrophages, epithelioid histiocytic cells, and lymphocytes. One patient was found to have mediastinal granulomatous lymphadenopathy; however, the evidence in other patients was insufficient for a diagnosis of systemic sarcoidosis. There were no significant differences between groups with and without granuloma regarding clinical manifestations, laboratory findings, response to immunomodulating therapies, or myopathological profiles. We established a new form of inclusion body myositis showing granuloma formation in muscle tissue. Inclusion body myositis and granuloma formation could have identical pathomechanisms concerning dysregulation of autophagy.

    Effects of inclusive school settings for students in six Indiana school corporations were investigated. Results reveal that students without disabilities educated in inclusive settings made significantly greater academic progress in mathematics and reading. For students with disabilities, there were no significant differences in reading and math achievement across the comparison groups. However, a review of group means and the percentage of students making comparable or greater than average academic progress when compared to students without disabilities indicates a pattern in favor of inclusive settings. The academic progress of students with specific disability labels, namely, learning disabilities and mild mental handicaps, also supported inclusive education.

    Textural and mineral-chemical data on freeze-thaw disaggregated refractory inclusions from the Murchison meteorite are reported. The data were obtained with neutron activation analysis, SEM, and spectroscopy, the study revealed corundum-bearing inclusions, spinel-hibonite aggregates and spherules, and spinel-pyroxene and elivine-pyroxene inclusions. One of the three spinel-, pyroxene-, forsterite-rich inclusions had an amoeba-shaped spinel-pyroxene core, implying vapor-to-solid condensation and therefore crystallization from a melt. It is concluded that the meteorite formation encompassed diverse nebular materials, and that further studies of the meteorite will enhance the data base on the planetary nebular processes.

    The philosophy of inclusion for people with intellectual and developmental disabilities (IDD) has evolved over the last 50 years. Over time, inclusion research has shifted from a focus on deinstitutionalization to understanding the extent to which individuals with IDD are meaningfully involved in the community and social relationships. Yet, there has been no agreed on way to measure inclusion. Many different measurement and data collection techniques have been used in the literature. This study proposes a brief measure of inclusion that can be used with family members and on survey instruments.

  11. Chemical zonation in olivine-hosted melt inclusions

    Significant zonation in major, minor, trace, and volatile elements has been documented in naturally glassy olivine-hosted melt inclusions from the Siqueiros Fracture Zone and the Galapagos Islands. Components with a higher concentration in the host olivine than in the melt (e.g., MgO, FeO, Cr2O3, and MnO) are depleted at the edges of the zoned melt inclusions relative to their centers, whereas except for CaO, H2O, and F, components with a lower concentration in the host olivine than in the melt (e.g., Al2O3, SiO2, Na2O, K2O, TiO2, S, and Cl) are enriched near the melt inclusion edges. This zonation is due to formation of an olivine-depleted boundary layer in the adjacent melt in response to cooling and crystallization of olivine on the walls of the melt inclusions, concurrent with diffusive propagation of the boundary layer toward the inclusion center. Concentration profiles of some components in the melt inclusions exhibit multicomponent diffusion effects such as uphill diffusion (CaO, FeO) or slowing of the diffusion of typically rapidly diffusing components (Na2O, K2O) by coupling to slow diffusing components such as SiO2 and Al2O3. Concentrations of H2O and F decrease toward the edges of some of the Siqueiros melt inclusions, suggesting either that these components have been lost from the inclusions into the host olivine late in their cooling histories and/or that these components are exhibiting multicomponent diffusion effects. A model has been developed of the time-dependent evolution of MgO concentration profiles in melt inclusions due to simultaneous depletion of MgO at the inclusion walls due to olivine growth and diffusion of MgO in the melt inclusions in response to this depletion. Observed concentration profiles were fit to this model to constrain their thermal histories. Cooling rates determined by a single-stage linear cooling model are 150-13,000 °C h-1 from the liquidus down to ~1,000 °C, consistent with previously determined cooling rates for

  12. Sr isotope variations in olivine-hosted melt inclusions from continetal basalts: evaluating primary vs secondary signatures of melt inclusions

    2003-04-01

    Melt inclusions have become the focus of intense study in constraining the sources involved in magma production in MORB and OIB. Such inclusions retain a wide variety of major and trace element signatures that have been typically attributed to various mantle sources without significant inputs from secondary magmatic processes such as crustal contamination. Sr isotopes of melt inclusions from continental basalts affected by crustal contamination suggest that highly variable major and trace element signatures in melt inclusions result from crustal contamination, not heterogeneous mantle sources. This may result from the inherent ability of melt inclusions to capture melt from regions in which rapid cooling and rapid olivine growth can occur. More specifically, rapid olivine growth, and subsequent melt capture, may be more likely to occur along wallrock/magma interfaces where a wide variety of crustally modified liquids may be present. Accordingly, melt inclusions captured in olivine phenocrysts from crustally contaminated basalts which retain elevated MgO contents (6 to 8 weight percent) reflect the widest range of Sr isotope signatures found in all phenocrysts and groundmass samples. In effect, the largest overall range of Sr isotopes is observed in olivine-hosted melt inclusions suggesting that melt inclusions are more likely to record the effects of secondary processes, rather than primary magmatic signatures. As such, caution should be exercised when using melt inclusions to identify mantle signatures, and Sr isotopes offer an excellent opportunity in which to evaluate the modifying effects of open-system processes affecting basalts.

  13. Fluid Inclusions in Extraterrestrial Samples Fact or Fiction?

    2000-01-01

    Over the years there have been numerous reports of liquid inclusions in meteorites. Roedder reviews the reported occurrences of liquid inclusions in meteorites and states that "silicate-melt inclusions are expectable and apparently ubiquitous, but the presence of actual liquid inclusions (i.e., with moving bubbles at room temperature) would seem almost impossible." The reason for this conclusion is that meteorites (presumably) form in space at high temperatures and very low pressures where liquid water (or carbon dioxide) is not stable. Perhaps the most infamous report of fluid inclusions in meteorites was that of Warner et al. In that study, the authors reported the presence of two-phase, liquid-vapor inclusions in a diogenite from Antarctica. This report of fluid inclusions generated considerable interest in the meteorite community, and caused many to question existing models for the origin of the diogenites. This interest was short-lived however, as later investigations of the same samples showed that the inclusions were most likely artifacts. Rudnick et al. showed that many of the inclusions in meteorites prepared at the Johnson Space Center contained a fluid that fluoresced strongly under the laser beam on the Raman microprobe. They interpreted this to indicate that the inclusions contained Almag oil used in the preparation of thin sections. Presumably, the Almag oil entered empty vesicles along fractures that were opened intermittently during cutting. Here, the occurrence of unambiguous fluid inclusions that could not have been introduced during sample preparation are described in samples from two different extraterrestrial environments. One environment is represented by the SNC (martian) meteorites ALH 84001 and Nakhla. The second environment is represented by the Monahans 1998 meteorite that fell recently in the USA.

  14. Fluid inclusion analyses of detrital quartz grains - new Provenance Tool

    SciTech Connect

    Bloch, J.D.

    1985-02-01

    Preliminary analyses by microthermometry of fluid inclusions in detrital quartz of the Upper Cambrian Lamotte Sandstone revealed the occurrence of 2 distinct groups of aqueous fluid inclusions. Specific salinity signatures and homogenization temperatures may be used to distinguish specific granite types of the source rock terrain. The inclusions chosen for analysis occur in isolated clusters or are randomly distributed within a grain, commonly in association with mineral inclusions of zircon, sphene, rutile, and/or tourmaline. Secondary inclusions are present in the Lamotte but are not included in this study. The first group of inclusions is characterized by low salinities (< 1.0-8.0 wt.% eq. NaCl), the second by high salinities (12.1-29.6 wt. % eq. NaCl). Final melting temperatures as low as -30.6/sup 0/C indicate the presence of divalent ions in these inclusions. Both groups yield homogenization temperatures of between 150/sup 0/C and 220/sup 0/C. The low-salinity inclusions occur predominantly in subrounded to well-rounded sand less than 1.0 mm in size that is derived from a distal source. The brine inclusions occur exclusively in subangular to angular gravel 2.0-3.0 mm in size, implying a more proximal source area. A comparison of these inclusions with inclusions found in the granites of the apparent source terrain indicates that a medium-silica amphiboleorthoclase granite (Slabtown type) or a low-silica amphibole-plagioclase granite (Sivermines type) or both are the primary source rocks for this quartz. These granite types have limited areal distribution in the present day St. Francois mountains and the identification of these granite types as the source rock for the locally derived quartz has broad implications for reconstructing Cambrian depositional environments and paleostructure of the ancient St. Francois mountains.

  15. Ceramic Inclusions In Powder Metallurgy Disk Alloys: Characterization and Modeling

    2002-01-01

    Powder metallurgy alloys are increasingly used in gas turbine engines, especially as the material chosen for turbine disks. Although powder metallurgy materials have many advantages over conventionally cast and wrought alloys (higher strength, higher temperature capability, etc.), they suffer from the rare occurrence of ceramic defects (inclusions) that arise from the powder atomization process. These inclusions can have potentially large detrimental effect on the durability of individual components. An inclusion in a high stress location can act as a site for premature crack initiation and thereby considerably reduce the fatigue life. Because these inclusions are exceedingly rare, they usually don't reveal themselves in the process of characterizing the material for a particular application (the cumulative volume of the test bars in a fatigue life characterization is typically on the order of a single actual component). Ceramic inclusions have, however, been found to be the root cause of a number of catastrophic engine failures. To investigate the effect of these inclusions in detail, we have undertaken a study where a known population of ceramic particles, whose composition and morphology are designed to mimic the 'natural' inclusions, are added to the precursor powder. Surface connected inclusions have been found to have a particularly large detrimental effect on fatigue life, therefore the volume of ceramic 'seeds' added is calculated to ensure that a minimum number will occur on the surface of the fatigue test bars. Because the ceramic inclusions are irregularly shaped and have a tendency to break up in the process of extrusion and forging, a method of calculating the probability of occurrence and expected intercepted surface and embedded cross-sectional areas were needed. We have developed a Monte Carlo simulation to determine the distributions of these parameters and have verified the simulated results with observations of ceramic inclusions found in macro

  16. Inclusion of Scatter in HADES: Final Report

    2010-12-20

    Covert nuclear attack is one of the foremost threats facing the United States and is a primary focus of the War on Terror. The Domestic Nuclear Detection Office (DNDO), within the Department of Homeland Security (DHS), is chartered to develop, and improve domestic systems to detect and interdict smuggling for the illicit use of a nuclear explosive device, fissile material or radiologica1 material. The CAARS (Cargo Advanced Automated Radiography System) program is a major part of the DHS effort to enhance US security by harnessing cutting-edge technologies to detect radiological and nuclear threats at points of entry to the United States. DNDO has selected vendors to develop complete radiographic systems. It is crucial that the initial design and testing concepts for the systems be validated and compared prior to the substantial efforts to build and deploy prototypes and subsequent large-scale production. An important aspect of these systems is the scatter which interferes with imaging. Monte Carlo codes, such as MCNP (X-5 Monte Carlo Team, 2005 Revision) allow scatter to be calculatied, but these calculations are very time consuming. It would be useful to have a fast scatter estimation algorithm in a fast ray tracing code. We have been extending the HADES ray-tracing radiographic simulation code to model vendor systems in a flexible and quick fashion and to use this tool to study a variety of questions involving system performance and the comparative value of surrogates. To enable this work, HADES has been linked to the BRL-CAD library (BRL-CAD Open Source Project, 2010), in order to enable the inclusion of complex CAD geometries in simulations, scanner geometries have been implemented in HADES, and the novel detector responses have been included in HADES. A major extension of HADES which has been required by this effort is the inclusion of scatter in these radiographic simulations. Ray tracing codes generally do not easily allow the inclusion of scatter, because
