    Anthracnose caused by Colletotrichum gloeosporioides is one of the most important postharvest diseases in mango fruit, often causing huge economic losses. In this study, the effect of 1-methylcyclopropene (1-MCP) against anthracnose in postharvest mango fruit and the mechanisms involved were investigated. 1-MCP induced reactive oxygen species (ROS) generation, damaged the mitochondria and destroyed the integrity of plasma membrane of spores of C. gloeosporioides, significantly suppressing spore germination and mycelial growth of C. gloeosporioides. 1-MCP also decreased the decay incidence and lesion expansion of mango fruit caused by C. gloeosporioides. For the first time this study demonstrated that 1-MCP suppressed anthracnose of postharvest mango fruit by directly inhibiting spore germination and mycelial growth of C. gloeosporioides, thus providing a promising strategy for disease control.

    The optimal 1-methylcyclopropene (1-MCP) treatment to slow ripening of whole "Keitt" mangos, either alone or in combination with hot water treatment (HWT) (prior to or post 1-MCP) was identified. USDA-APHIS mandates that HWT can be used for control of fruit flies, but this may affect fruit response to 1-MCP. Mangos were evaluated by repeated measurement of nondestructive firmness, peel color, and ethylene production on the same mango fruits during 2 wk of ripening at 20 °C after treatment. The magnitude of ethylene production increased as a result of both 1-MCP and HWT. With softer mangos (65 N), treatment with 1-MCP alone delayed fruit softening and extended the number of days to full-ripeness (25 N) from 5 d in untreated fruit to 11 d. For these riper fruit, application of 1-MCP prior to HWT extended the days to full-ripeness to 9 d compared with 7 d when 1-MCP was applied after HWT. With firmer mangos (80 N), 1-MCP treatments alone prolonged the days to full-ripeness to 13 d as compared to 11 d for the untreated fruit. There was no significant concentration effect on firmness retention among 1-MCP treatments (0.5, 1.0, or 10.0 μL/L). HWT resulted in a faster rate of fruit softening, taking only 7 d to reach full-ripeness. Combining 1-MCP with HWT reduced the rate of softening compared to HWT alone, resulting in 9 to 11 d to full-ripeness. Application of 1-MCP before HWT showed a greater ability to reduce the rate of fruit softening compared with 1-MCP treatment after HWT.

    Kiwi fruits (Actinidia deliciosa C.F. Liang et A.R. Ferguson) were treated by prestorage conditioning (20 °C for 2 days), 1-methylcyclopropene (1-MCP, 1 ppm for 16 h) and conditioning plus 1-MCP. After the treatment the fruits were immediately stored at 0 °C during 24 weeks. Flesh firmness gradually decreased with storage time and the rate of its loss was lower in 1-MCP and conditioning plus 1-MCP treatments than those of control or conditioning. However, SSC, acidity and pH did not change among treatments. Starch content decreased during the storage time regardless of treatments. Oppositely the amount of reducing sugars increased at the same duration of the treatments. Rate and incidence of fruit decay was the lowest in fruit treated with conditioning plus 1-MCP treatment. Fruit decay mainly caused pathogen Botrytis cinerea and its rate significantly decreased with conditioning plus 1-MCP treatment. Ethylene and respiration abruptly increased after 8 weeks of storage, but their contents were lower in 1-MCP and conditioning plus 1-MCP. Total soluble phenolics, flavonoids, and total antioxidant capacities were much higher than in other treatments. Kiwi fruits treated with conditioning plus 1-MCP extended the shelf life by reducing the rate of fruit decay and softening during the storage. The bioactive compounds and total antioxidant status of fruits increased during the treatment.

    Effect of pre-harvest methyl jasmonate (MeJA) and post-harvest 1-methylcyclopropene (1-MCP) treatments on broccoli floret glucosinolate (GS) concentrations and quinone reductase (QR, an in vitro anti-cancer biomarker) inducing activity were evaluated two days prior to harvest, at harvest and at 10, 20, and 30 days of post-harvest storage at 4 °C. MeJA treatments four days prior to harvest of broccoli heads was observed to significantly increase floret ethylene biosynthesis resulting in chlorophyll catabolism during post-harvest storage and reduced product quality. Post-harvest treatment with 1-methylcyclopropene (1-MCP), which competitively binds to protein ethylene receptors, maintained post-harvest floret chlorophyll concentrations and product visual quality in both control and MeJA-treated broccoli. Transcript abundance of BoPPH, a gene which is responsible for the synthesis of pheophytinase, the primary enzyme associated with chlorophyll catabolism in broccoli, was reduced by 1-MCP treatment and showed a significant, negative correlation with floret chlorophyll concentrations. The GS, glucobrassicin, neoglucobrassicin, and gluconasturtiin were significantly increased by MeJA treatments. The products of some of the GS from endogenous myrosinase hydrolysis [sulforaphane (SF), neoascorbigen (NeoASG), N-methoxyindole-3-carbinol (NI3C), and phenethyl isothiocyanate (PEITC)] were also quantified and found to be significantly correlated with QR. Sulforaphane, the isothiocyanate hydrolysis product of the GS glucoraphanin, was found to be the most potent QR induction agent. Increased sulforaphane formation from the hydrolysis of glucoraphanin was associated with up-regulated gene expression of myrosinase (BoMyo) and the myrosinase enzyme co-factor gene, epithiospecifier modifier1 (BoESM1). This study demonstrates the combined treatment of MeJA and 1-MCP increased QR activity without post-harvest quality loss.

    Green asparagus was treated with 1-methylcyclopropene at three concentration levels at room temperature for 24 h after harvest to evaluate the postharvest quality during cold storage at 4°C. Comparing with the controls, the loss of vitamin C, decomposition of chlorophyll, and accumulation of the malonydiadehyde under treatments of 1-methylcyclopropene were reduced during storage. The enzyme activities in asparagus including peroxidase and phenylalanine ammonia lyase were inhibited by 1-methylcyclopropene treatments, while the activity of superoxide dismutase was enhanced. Based on non-significant difference of the treated samples with 6 ìl l-1, 1-methylcyclopropene treatments at 4 ìl l-1 could be selected to maintain postharvest quality of green asparagus and provide long storage life.

    In this study, changes in quality and various biochemical parameters of 'Idared' apples during prolonged shelf life period after ultra-low oxygen (ULO) storage were investigated. Additionally, the impact of the postharvest application of 1-methylcyclopropene (1-MCP) on different parameters was evaluated. After the harvest, apples were stored in the ULO storage for 6 months and then exposed to room temperature. Fruit firmness, peel color, and changes in sugars, organic acids and phenolics were monitored during the 3 weeks of shelf life. Malic acid, sugars and firmness decreased at room temperature. However, the color of the apples remained unchanged. The level of citric and ascorbic acid remained constant. Levels of phenolics in the peel increased significantly, whereas remained constant in the pulp of apples. 1-MCP treatment resulted in higher amounts of fructose and glucose, malic acid and greater firmness of apples. However, 1-MCP did not influence the phenolic content, ascorbic acid or color. The results obtained indicate that the content of different health-promoting compounds of apples does not change dramatically at room temperature. At the same time these results suggest that 1-MCP could be useful for maintaining certain quality and biochemical parameters and might extend the shelf life of apples.

    The responses of cherry tomato (Lycopersicon esculentum var. cerasiforme) fruits to post-harvest treatment with 1-MCP were investigated. The maturity stage at which 1-MCP application is most effective in delaying the ripening process was determined, and then the effects of different concentrations (0, 0.035, 0.07 and 0.11 microL/L) of 1-MCP on ethylene production, fruit softening, chlorophyll, lycopene and carotenoids contents of mature green (MG) cherry tomato fruits were assessed. 1-MCP at 0.07 and 0.11 microL/L reduced fruit C(2)H(4) production, delayed the C(2)H(4) peak at ambient temperature. Although 1-MCP at 0.035 microL/L was effective in retarding fruit ripening, it did not suppress endogenous ethylene production. Fruit softening was suppressed by 1-MCP, but its initiation was not affected by 1-MCP. The rate of chlorophyll degradation and its pattern of change with time, and the initiation of lycopene biosynthesis as well as its accumulation were all affected by 1-MCP, but only the accumulation of carotenoids was suppressed. Accumulation of lycopene and carotenoids was almost permanently hampered by 1-MCP at 0.07 microL/L or higher concentrations, and fruit color could not reach the control level even 2 weeks after 1-MCP treatment, indicating the close association of the metabolism of these pigments with ethylene perception. Since the concentration of 0.11 microL/L of 1-MCP was so high that it did not elicit additional response very much than 0.07 microL/L, these concentrations were considered to be practically effective concentrations for cherry tomato at MG stage. The effective 1-MCP concentrations might provide a useful reference to the levels of ethylene receptors as well as ethylene sensitivity in a specific fruit at given development stage.

    The effect of postharvest 1-methylcyclopropene and/or cold storage application on texture quality parameters during storage was determined. The changes in fruit quality (including weight loss, firmness, total soluble solids content, and ethylene production), cell wall material (including water-soluble fraction, ethylenediaminetetraacetic acid-soluble fraction, Na2CO3-soluble fraction, 4% KOH-soluble fraction, and 14% KOH-soluble fraction), and cell wall hydrolase activities (including polygalacturonase, endo-1,4-beta-D-glucanase, pectinesterase, alpha-L-arabinofuranosidase, and beta-galactosidase) were periodically measured up to 25 days after postharvest treatments. The application of cold storage reduced weight loss, ethylene production, and delayed ripening of blueberry fruit. The inhibition of senescence was associated with suppressed increase in cell wall hydrolase activities and retarded solubilization of pectins and hemicelluloses. Furthermore, no obvious differences in firmness, weight loss, ethylene production, and cell wall hydrolase activities between fruits with or without 1-methylcyclopropene application were observed, while significant lower levels of the detected parameters were found in cold storage fruit compared with fruit stored in room temperature. Thus, cold storage can be viewed as an effective means to extend the shelf life of blueberry fruit.

    Onion (Allium cepa) is regarded as a nonclimacteric vegetable. In onions, however, ethylene can suppress sprouting while the ethylene-binding inhibitor 1-methylcyclopropene (1-MCP) can also suppress sprout growth; yet, it is unknown how ethylene and 1-MCP elicit the same response. In this study, onions were treated with 10 μL L(-1) ethylene or 1 μL L(-1) 1-MCP individually or in combination for 24 h at 20°C before or after curing (6 weeks) at 20°C or 28°C and then stored at 1°C. Following curing, a subset of these same onions was stored separately under continuous air or ethylene (10 μL L(-1)) at 1°C. Onions treated with ethylene and 1-MCP in combination after curing for 24 h had reduced sprout growth as compared with the control 25 weeks after harvest. Sprout growth following storage beyond 25 weeks was only reduced through continuous ethylene treatment. This observation was supported by a higher proportion of down-regulated genes characterized as being involved in photosynthesis, measured using a newly developed onion microarray. Physiological and biochemical data suggested that ethylene was being perceived in the presence of 1-MCP, since sprout growth was reduced in onions treated with 1-MCP and ethylene applied in combination but not when applied individually. A cluster of probes representing transcripts up-regulated by 1-MCP alone but down-regulated by ethylene alone or in the presence of 1-MCP support this suggestion. Ethylene and 1-MCP both down-regulated a probe tentatively annotated as an ethylene receptor as well as ethylene-insensitive 3, suggesting that both treatments down-regulate the perception and signaling events of ethylene.

    Consumption of minimally processed fruit and vegetables has increased significantly in the past few years due to the consumers' life style. The aim of this study was to evaluate the effect of treatment with ascorbic acid or calcium chloride on the quality parameters of fresh-cut kiwifruit prepared from fruit previously stored for 3 months, either treated or not treated with 1-methylcyclopropene (1-MCP) before storage. Harvested fruit were treated with 1 microL L(-1) 1-MCP for 20 h at room temperature ( approximately 20 degrees C) (MCP) or had no treatment (C) and were then stored at 0 degrees C. After 3 months, fruit were removed from storage, peeled, and cut longitudinally in quarters, dipped in 2% ascorbic acid (Asc), 2% calcium chloride (Ca), or just water (cont), and kept at 2 degrees C for 8 days. Measurements of firmness, soluble solids content (SSC) ( degrees Brix), color (CIE L*, a*, b*), electrolyte leakage, sugars, organic acids, total phenolics, and antioxidant activity (DPPH and ABTS) were performed at 0, 4, and 8 days. A taste panel was performed on the seventh shelf life day. It was shown that whole MCP-treated kiwifruit kept better than the control through the 3 months storage, this effect being lost through the fresh-cut shelf life period. Furthermore, the postcut dip on 2% CaCl(2) was effective on delaying softening and browning of fresh-cut kiwifruit, which were also the fruit preferred by panelists. Both ascorbic acid and CaCl(2) were effective on preserving or improving nutritional properties (phenolics, ascorbic acid, DPPH, and ABTS) mainly in the first 4 days of shelf life. The CaCl(2) had a further beneficial effect until 8 shelf life days. It is suggested that CaCl(2) is better in keeping overall quality through 8 days of shelf life at 2 degrees C in fresh-cut kiwifruit followed by Asc, and 1-MCP has negligible effect in the conditions of this experiment.

    The objective of the present study was to simultaneously evaluate the effect of a postharvest treatment on the pepper's antioxidant content and its ability to retain its economical value during the postharvest period. The fruits were pretreated by modified atmosphere packaging (MAP) with or without treatment with 1-methylcyclopropene (1-MCP) before cold storage at 10°C. Changes in the levels of non-enzymatic antioxidants, including the total phenolic, ascorbic acid levels and the total glutathione level, as well as enzymatic antioxidants, including ascorbate peroxidase (APX), glutathione reductase (GR), and catalase (CAT), were determined. Both treatments successfully extended the shelf life of the fruit for up to 25 days, and a high level of antioxidant capacity was maintained throughout the storage period. However, 1-MCP treatment maintained the high antioxidant capacity for a longer period of time. The 1-MCP-treated peppers maintained high levels of phenolic content, a high reduced glutathione (GSH)/oxidised glutathione (GSSG) ratio, decreased levels of ascorbic acid and CAT activity, and increased levels of APX and GR compared with the peppers that were not treated with 1-MCP. The overall results suggested that a combination of 1-MCP and MAP was the most effective treatment for extending shelf life while retaining the nutritional benefits.

    2016-01-01

    Hardy kiwifruits (Actinidia arguta) were treated with 20 μl/l 1-methylcyclopropene (1-MCP) for 16 h at 10 °C and subsequently stored at 1 ± 0.5 °C. Anticancer properties of the fruit extracts were tested against five different human cancer cells. The hardy kiwifruits, without 1-MCP treatment, showed increases in both respiration and ethylene production rates during fruit storage. The 1-MCP treatment remarkably inhibited fruit ripening by reducing respiration and ethylene production. Fruits with the 1-MCP treatment could be stored for up to 5 weeks by maintaining higher fruit firmness, ascorbic acid and total phenolic contents compared to the control. The hardy kiwifruit extracts showed anti-proliferative effects to Hep3B and HeLa cells but not to HT29, HepG2 and LoVo cells. These results suggest that the application of 1-MCP at harvest effectively delayed the ripening process of the fruits, and the fruit extract had beneficial effects for the prevention of human cancer growth.

    The ethylene perception inhibitor 1-methylcyclopropene (1-MCP) has been critical in understanding the hormone's mode of action. However, 1-MCP may trigger other processes that could vary the interpretation of results related until now to ethylene, which we aim to understand by using transcriptomic analysis. Transcriptomic changes in ethylene and 1-MCP-treated 'Navelate' (Citrus sinensis L. Osbeck) oranges were studied in parallel with changes in ethylene production, respiration and peel damage. The effects of compounds modifying the levels of the ethylene co-product cyanide and nitric oxide (NO) on fruit physiology were also studied. Results suggested that: 1) The ethylene treatment caused sub-lethal stress since it induced stress-related responses and reduced peel damage; 2) 1-MCP induced ethylene-dependent and ethylene-independent responsive networks; 3) 1-MCP triggered ethylene overproduction, stress-related responses and metabolic shifts aimed to cope with cell toxicity, which mostly affected to the inner part of the peel (albedo); 4) 1-MCP increased respiration and drove metabolism reconfiguration for favoring energy conservation but up-regulated genes related to lipid and protein degradation and triggered the over-expression of genes associated with the plasma membrane cellular component; 5) Xenobiotics and/or reactive oxygen species (ROS) might act as signals for defense responses in the ethylene-treated fruit, while their uncontrolled generation would induce processes mimicking cell death and damage in 1-MCP-treated fruit; 6) ROS, the ethylene co-product cyanide and NO may converge in the toxic effects of 1-MCP.

    2007-12-26

    1-methylcyclopropene (1-MCP), an ethylene inhibiting regulator, is commercially available in the form of an inclusion complex with alpha-cyclodextrin (alpha-CD). In this study, molecular encapsulation of gaseous 1-MCP into aqueous alpha-CD was investigated in a closed, agitated vessel with a flat gas-liquid interface. Molecular encapsulation of gaseous 1-MCP by alpha-CD is a simultaneous two-step reaction which involves the aqueous dissolution of gaseous 1-MCP and the encapsulation of the dissolved molecules by alpha-CD. The kinetics and mechanism of molecular encapsulation were analyzed based on the depletion rate of 1-MCP in the headspace of the vessel. The encapsulation rates could be explained quantitatively by the gas absorption theory with a pseudo-first-order reaction between 1-MCP and alpha-CD. The negative value of the calculated apparent activation energy of encapsulation (-24.4 kJ/mol) implied the significant effect of exothermic aqueous dissolution of 1-MCP. An encapsulation temperature of 15 degrees C was optimal; at this temperature, the highest 1-MCP yield and best inclusion ratio of inclusion complex were obtained. Changes in the X-ray diffraction pattern suggested that the crystal lattice structure of alpha-CD was altered upon inclusion of 1-MCP.

    2016-03-01

    The effects of ethylene and 1-methylcyclopropene (1-MCP) on apple fruit volatile biosynthesis and gene expression were investigated. Statistical analysis identified 17 genes that changed significantly in response to ethylene and 1-MCP treatments. Genes encoding branched-chain amino acid aminotransferase (BCAT), aromatic amino acid aminotransferase (ArAT) and amino acid decarboxylases (AADC) were up-regulated during ripening and further enhanced by ethylene treatment. Genes related to fatty acid synthesis and metabolism, including acyl-carrier-proteins (ACPs), malonyl-CoA:ACP transacylase (MCAT), acyl-ACP-desaturase (ACPD), lipoxygenase (LOX), hydroperoxide lyase (HPL), alcohol dehydrogenase (ADH), pyruvate decarboxylase (PDC2), β-oxidation, acyl-CoA synthetase (ACS), enoyl-CoA hydratase (ECHD), acyl-CoA dehydrogenase (ACAD), and alcohol acyltransferases (AATs) also increased during ripening and in response to ethylene treatment. Allene oxide synthase (AOS), alcohol dehydrogenase 1 (ADH1), 3-ketoacyl-CoA thiolase and branched-chain amino acid aminotransferase 2 (BCAT2) decreased in ethylene-treated fruit. Treatment with 1-MCP and ethylene generally produced opposite effects on related genes, which provides evidence that regulation of these genes is ethylene dependent.

    1-Methylcyclopropene (1-MCP) is an excellent safe and commercially available ethylene antagonist for the preservation of horticultural products. However 1-MCP has to be stored in absorbents due to its gaseous and unstable characteristics. In this paper cucurbit[6]uril (CB[6]) was used as the absorbent to encapsulate 1-MCP, and the resultant inclusion complex was characterized by IR, powder X-ray diffraction, thermal analysis, and fluorescent spectra. The effects of encapsulation conditions on the formation of inclusion complex were also investigated. The amount of 1-MCP encapsulated by CB[6] was about 4.5% by weight when the initial concentration of 1-MCP, encapsulation temperature, CB[6] concentration, and encapsulation time were set at 75 mL/L, 20 °C, 30 mM, and 8 h, respectively. Furthermore, the release of 1-MCP from the complex can be realized with different solutions such as sodium bicarbonate, benzoic acid, and distilled water. CB[6] can be used as an excellent absorbent for encapsulation of 1-MCP.

    The effect of the ethylene receptor competitor 1-methylcyclopropene (1-MCP) and the legally approved disinfectant chlorine dioxide (ClO2) on preservation of the green walnut fruit during storage was investigated. Green Chinese walnut fruit cv. Xilin No.2 was harvested on commercial maturity and stored at 0-1 °C after the fruit was treated by water (control), 80 mg L(-1)ClO2 (ClO2), 0.5 μL L(-1)1-MCP (1-MCP), or combination treatment of 80 mg L(-1) ClO2 with either 0.1 μL L(-1) 1-MCP (0.1 1-MCP+ ClO2) or 0.5 μL L(-1) 1-MCP (0.5 1-MCP+ ClO2). During storage, respiration, ethylene production, phenolics content, antioxidative activity, weight changes, decay of the fruit and kernel traits of acid value, peroxide value,free fatty were measured. All treatments decreased postharvest respiration intensity in different degrees and inhibited ethylene production peak. ClO2 increased the total phenol and flavonoid content of the green fruit compared with other treatments and the control (P < 0.05), but not did the total antioxidant activity for this treatment. After 42-day storage, ClO2 remained higher fresh weight and lower decay index than control, while 1-MCP increased the fruit decay index. Final acid values of kernel from ClO2, control and 0.1 1-MCP+ ClO2 were not different from their initial values, which from 0.5 1-MCP increased. Final peroxide value for kernel from ClO2 showed no change during storage but increased at least 1.0-fold for other treatments. ClO2 preserved 99.9 % of initial free fatty acid, similar to that for the control (99.8 %), whereas 0.5 1-MCP preserved only 95.7 %. ClO2 is of potential in decay retardation and kernel traits maintenance of green walnut fruit, whereas the 1-MCP has a negative effect for decay control on walnut.

    The effect of the application of 1-methylcyclopropene (1-MCP) and wax emulsions, alone or combined, on composition analysis, vitamin C, polyphenols, and antioxidant capacity of soursop was evaluated. Fruits were stored as follows: at 25 °C (control), and at 16 °C: fruits sprayed with candelilla or flava emulsions, fruits treated with 1500 nL/L of 1-MCP (20 °C, 12 h), and fruits treated with 1-MCP and then sprayed with emulsions. Fruits were allowed to ripen and the edible part was used for analysis. Only fruits stored at 16 °C without 1-MCP showed visible symptoms of chilling injury. Fruits treated with 1-MCP combined with flava emulsion maintained in greater extent their vitamin C content, dietary fiber, total phenolics content, and antioxidant activity. The combination of 1-MCP and emulsions can be utilized in postharvest handling of soursop because this combination can preserve its nutritional composition and antioxidant activity.

    Cape gooseberry (Physalis peruviana L.) fruits are highly perishable berries that exhibit a climacteric respiratory behavior. The objective of this study was to evaluate the effect of ethylene and the ethylene action inhibitor 1-methylcyclopropene on the postharvest behavior of cape gooseberry fruits (ecotype Colombia). Fruits were treated with ethylene, in an ethephon application (1000 µL L(-1)), and pretreated with 1-methylcyclopropene (1 µL L(-1)), 1-methylcyclopropene+ethylene, and results compared with a control without application. Subsequently, the fruits were maintained at room temperature (20 ℃, 75% RH) for up to 11 days. The pretreatment of the cape gooseberry fruits with 1-methylcyclopropene delayed most of the ripening-associated parameters, with a reduction in the respiration rate and ethylene production, skin color development, total soluble solids, total carotenoid content, loss of firmness, loss of total titratable acidity and emission of volatile compounds such as ethyl octanoate, ethyl butanoate, ethyl decanoate, and hexyl decanoate. Conversely, application of ethephon accelerated most of these physiological changes and also overcame most of the effects prevented by the ethylene action inhibitor. Altogether, the results supported the idea of a climacteric-like behavior for cape gooseberry fruits and pointing out that the pretreatment with 1-methylcyclopropene may be a promising and efficient postharvest treatment to delay maturity and extend the postharvest period.

    Xyloglucan endotransglucosylase/hydrolase (XTH) is thought to contribute to fruit softening by degrading xyloglucan that is a predominant hemicellulose in the cell wall. In this study, two full-length XTH genes (DKXTH1 and DKXTH2) were identified from 'Fupingjianshi' persimmon fruit, and the expression level of both XTH genes was investigated during softening for 18-24 d using RT-qPCR. Sequence analysis showed that DKXTH1 and DKXTH2 contained a putative open reading frame of 861 and 876 bp encoding polypeptides of 287 and 292 amino acid residues, respectively, which contained the conserved DEIDFEFLG motif of XTH, a potential N-linked glycosylation signal site. RT-qPCR analysis showed that DKXTH1 and DKXTH2 in untreated fruit had different expression patterns during fruit softening, in which maximum expression occurred on days 3 and 12 of ripening, respectively. 1-Methylcyclopropene (1-MCP) and gibberellic acid (GA(3)) treatments delayed the softening and ethylene peak of persimmon fruit, as well as suppressed the expression of both XTH genes, especially DKXTH1. These results indicated that the expression of both XTH genes might be ethylene dependent action, and closely related to softening of persimmon in the early (DKXTH1) and later (DKXTH2) ripening stages.

    The effect of the application of 1-methylcyclopropene (1-MCP) and wax emulsions, alone or combined, on composition analysis, vitamin C, polyphenols, and antioxidant capacity of soursop was evaluated. Fruits were stored as follows: at 25°C (control), and at 16°C: fruits sprayed with candelilla or flava emulsions, fruits treated with 1500 nL/L of 1-MCP (20°C, 12 h), and fruits treated with 1-MCP and then sprayed with emulsions. Fruits were allowed to ripen and the edible part was used for analysis. Only fruits stored at 16°C without 1-MCP showed visible symptoms of chilling injury. Fruits treated with 1-MCP combined with flava emulsion maintained in greater extent their vitamin C content, dietary fiber, total phenolics content, and antioxidant activity. The combination of 1-MCP and emulsions can be utilized in postharvest handling of soursop because this combination can preserve its nutritional composition and antioxidant activity. PMID:24892105

    The effect of 1-methylcyclopropene (1-MCP), which inhibits the reception of ethylene, on the following has been studied: hydrogen peroxide generation, oxalate oxidase activity, peroxidase activity, catalase activity, and lignin accumulation in infected leaves of soft spring wheat (Triticum aestivum L.) breeds that differ in their resistance to the causative agent of leaf blotch Septoria nodorum Berk. A decrease in the development of leaf blotch in wheat leaves under the influence of 1-MCP was, on one hand, followed by an inhibition of catalase activity; on the other hand, it was accompanied by an increase in oxalate oxidase and peroxidase activity, as well as an accumulation of H2O2 in tissues and lignin in the infected zone. The role of the ethylene reception system in the plants' protective response to infection with a hemibiotrophic pathogen, the causative agent of leaf blotch, is discussed.

    The objective of this study was to evaluate the interaction between controlled atmosphere (CA), CA+1-methylcyclopropene (1-MCP) and dynamic controlled atmosphere monitored by respiratory quotient (DCA-RQ) with three fruit maturity stages at harvest (early harvest date, optimal harvest date and late harvest date) on 'Galaxy' apple metabolism and quality after harvest and 9months storage plus 7days of shelf life at 20°C. Fruit stored under dynamic controlled atmosphere monitored by respiratory quotient 1.3 (DCA-RQ 1.3) showed lower ethylene production, respiration rate, mealiness and higher flesh firmness in comparison to CA stored fruit, but did not differ from those treated with 1-MCP. The dynamic controlled atmosphere monitored by respiratory quotient 1.5 (DCA-RQ 1.5) increased the acetaldehyde, ethanol and ethyl acetate concentration, regardless of the fruit maturity at harvest. The storage of 'Galaxy' apple under DCA-RQ 1.3 is efficient in keeping quality regardless of the maturity stage at harvest.

    The influence of four postharvest treatments, 1-methylcyclopropene (1-MCP), carbon dioxide (CO2), and nitrogen (N2), followed by fruit storage at 10 degrees C or of hydrocooling (H2O) at 1 degrees C, followed by storage at 0 degrees C on fruit quality, carotenoids, and abscisic acid (ABA) content as well as on ethylene and carbon dioxide production of "Spring Belle" peach fruits, has been examined. Ethylene production was reduced by all the treatments and raised after transfer the fruits at 20 degrees C, their ethylene production in general being lower than that of fruits continuously held at 20 degrees C. Nevertheless, 1-MCP removal enhanced the rise in ethylene occurring at 20 degrees C by the end of storage. Those changes were likely related to fruit softening but not to changes in color or in the soluble solid content (SSC). HPLC analyses showed a relative high content of xanthophylls, particularly violaxanthin. In fruits maintained in air at 20 degrees C, violaxanthin and beta-carotene contents decreased while beta-criptoxanthin increased. ABA content showed a great increase in 1-MCP and significant decrease in carbon dioxide and hydrocooling treated peaches. The results indicated hydrocooling, in combination with low temperature storage, as the best treatment maintaining fruit firmness due to the lowered respiration rate and the content of relevant carotenoids.

    Chemokines constitute a family of chemoattractant cytokines and are subdivided into four families on the basis of the number and spacing of the conserved cysteine residues in the N-terminus of the protein. Chemokines play a major role in selectively recruiting monocytes, neutrophils, and lymphocytes, as well as in inducing chemotaxis through the activation of G-protein-coupled receptors. Monocyte chemoattractant protein-1 (MCP-1/CCL2) is one of the key chemokines that regulate migration and infiltration of monocytes/macrophages. Both CCL2 and its receptor CCR2 have been demonstrated to be induced and involved in various diseases. Migration of monocytes from the blood stream across the vascular endothelium is required for routine immunological surveillance of tissues, as well as in response to inflammation. This review will discuss these biological processes and the structure and function of CCL2. PMID:19441883

    Quarantine treatment enables export of avocado fruit (Persea americana) to parts of the world that enforce quarantine against fruit fly. The recommended cold-based quarantine treatment (storage at 1.1°C for 14 days) was studied with two commercial avocado cultivars 'Hass' and 'Ettinger' for 2 years. Chilling injuries (CIs) are prevalent in the avocado fruit after cold-quarantine treatment. Hence, we examined the effect of integrating several treatments: modified atmosphere (MA; fruit covered with perforated polyethylene bags), methyl jasmonate (MJ; fruit dipped in 2.5 μM MJ for Hass or 10 μM MJ for Ettinger for 30 s), 1-methylcyclopropene (1-MCP; fruit treated with 300 ppb 1-MCP for 18 h) and low-temperature conditioning (LTC; a gradual decrease in temperature over 3 days) on CI reduction during cold quarantine. Avocado fruit stored at 1°C suffered from severe CI, lipid peroxidation, and increased expression of chilling-responsive genes of fruit peel. The combined therapeutic treatments alleviated CI in cold-quarantined fruit to the level in fruit stored at commercial temperature (5°C). A successful therapeutic treatment was developed to protect 'Hass' and 'Ettinger' avocado fruit during cold quarantine against fruit fly, while maintaining fruit quality. Subsequently, treated fruit stored at 1°C had a longer shelf life and less decay than the fruit stored at 5°C. This therapeutic treatment could potentially enable the export of avocado fruit to all quarantine-enforcing countries. Similar methods might be applicable to other types of fruit that require cold quarantine.

    Experimental autoimmune orchitis (EAO) is characterized by an interstitial mononuclear cell infiltrate and a severe lesion of seminiferous tubules with germ cells that undergo apoptosis and sloughing. The mechanism by which immune cells migrate and extravasate in the testicular interstitium is poorly understood. The aim of this study was to detect the variations in the expression of monocyte chemoattractant protein-1 (MCP-1/CCL2) and its receptor in the testis of rats undergoing autoimmune orchitis. EAO was induced in Sprague-Dawley adult rats by active immunization with an emulsion of testicular homogenate and complete Freund adjuvant using Bordetella pertussis as co-adjuvant. Control rats injected with saline and adjuvants and normal untreated rats were also studied. By ELISA we observed a significant increase of MCP-1 in the testicular fluid (TF) and in the conditioned medium obtained from cultures of testicular macrophages of rats with EAO compared with control groups. By immunohistochemistry, an increase in MCP-1 expression was observed in mononuclear, endothelial, Leydig and peritubular cells. MCP-1 immunoreactivity was also detected in Sertoli cell cytoplasm of rats with severe orchitis. A 2-fold increase in the number of mononuclear cells that express CCR2 was also found in rats with orchitis compared with controls. In conclusion, we demonstrated in vivo that MCP-1 is highly expressed in testicular interstitial cells suggesting that this chemokine has an important role in recruiting immune cells to the testis in rats undergoing autoimmune orchitis.

    In this study, we examined the involvement of chemokine monocyte chemoattractant protein-1 (MCP-1) in the spinal cord of a rat model of cancer-induced bone pain (CIBP). In this model, CIBP was established by an intramedullary injection of Walker 256 cells into the tibia of rats. We observed a significant increase in expression levels of MCP-1 and its receptor CCR2 in the spinal cord of CIBP rats. Furthermore, the intrathecal administration of an anti-MCP-1 neutralizing antibody attenuated the mechanical allodynia established in CIBP rats. Likewise, an intrathecal injection of exogenous recombinant MCP-1 induced a striking mechanical allodynia in naïve rats. These results suggest that increases in spinal MCP-1 and CCR2 expression are involved in the development of mechanical allodynia associated with bone cancer rats.

    Four stochastic microsensors based on nanostructured materials (graphene, maltodextrin (MD), and diamond) integrated in miniaturized platforms were proposed. Monocyte chemoattractant protein-1 (MCP-1) is a pro-inflammatory cytokine whose main function is to regulate cell trafficking. It is correlated with the incidence of cardiovascular diseases and obesity, and was used as the model analyte in this study. The screening of whole blood samples for MCP-1 can be done for concentrations ranging from 10-12 to 10-8 g mL-1. The method was used for both qualitative and quantitative assessments of MCP-1 in whole blood samples. The lowest quantification limits for the assay of MCP-1 (1 pg mL-1) were reached when the microsensors based on protoporphyrin IX/Graphene-Au-3 and on MD/Graphene were employed in the platform design.

    The use of paclitaxel (Taxol®), a microtubule stabilizer, for cancer treatment is often limited by its associated peripheral neuropathy (chemotherapy-induced peripheral neuropathy, CIPN) which predominantly results in sensory dysfunction including chronic pain. Here we show that paclitaxel CIPN was associated with an induction of chemokine monocyte chemoattractant protein-1 (MCP-1) and its cognate receptor CCR2 in primary sensory neurons of dorsal root ganglia (DRG). Immunostaining revealed that MCP-1 was mainly expressed in small nociceptive neurons while CCR2 was expressed in large and medium-sized myelinated neurons. Direct application of MCP-1 consistently induced intracellular calcium increases in DRG large and medium-sized but not small neurons mainly dissociated from paclitaxel- but not vehicle-treated animals. Paclitaxel also induced increased expression of MCP-1 in spinal astrocytes but no CCR2 signal was detected in spinal cord. Local blockade of MCP-1/CCR2 signaling by anti-MCP-1 antibody or CCR2 antisense oligodeoxynucleotides significantly attenuated paclitaxel CIPN phenotypes including mechanical hypersensitivity and loss of intraepidermal nerve fibers (IENFs) in hindpaw glabrous skin. These results suggest that activation of paracrine MCP-1/CCR2 signaling between DRG neurons plays a critical role in the development of paclitaxel CIPN and targeting MCP-1/CCR2 signaling could be a novel therapeutic approach.

    This study aimed to investigate the function and signaling pathway of Toll-like receptor 4 (TLR4) in oxidized low-density lipoprotein (oxLDL)-induced up-regulated expressions of oxidized LDL receptor 1 (LOX-1), monocyte chemoattractant protein 1 (MCP-1), and vascular cell adhesion molecule 1 (VCAM-1) in human umbilical vein endothelial cells (HUVECs). HUVECs were incubated with different oxLDL concentrations (0, 20, 40, 60, and 80 μg/mL) for 24 and 48 h. The influence of oxLDL on TLR4, LOX-1, MCP-1, and VCAM-1 expressions in HUVECs was detected by real-time polymerase chain reaction and Western blot analysis. HUVECs were transfected with small interfering RNA targeting TLR4 (siTLR4), in which protein expressions of LOX-1, MCP-1, and VCAM-1, and the nuclear translocation of NF-kB (P50) were detected by Western blot. After 48 h of processing HUVECs with pyrrolidine dithiocarbamate (PDTC), protein expressions of TLR4, LOX-1, MCP-1, and VCAM- 1 were detected by Western blot. OxLDL induced a concentration-dependent up-regulation of mRNA and protein expressions of TLR4, LOX-1, MCP-1, and VCAM-1 in HUVECs (P < 0.001). siTLR4 significantly reduced protein expressions of LOX-1, MCP-1, VCAM-1, and reduced the NF-kB (P50) nuclear translocation (P < 0.001). PDTC significantly inhibited protein expressions of TLR4, LOX-1, MCP- 1, and VCAM-1 (P < 0.001). Results of this study demonstrate that the TLR4/NF-κB signaling pathway has an important function in the up-regulation of oxLDL-induced expressions of LOX-1, MCP-1, and VCAM-1 in HUVECs.

    Profibrotic growth factors and inflammatory chemokines have been implicated in the pathogenesis of diabetic nephropathy (DN). However, measurement of urinary monocyte chemoattractant protein-1 (MCP-1) and connective tissue growth factor (CCN2) as prognostic markers has not previously been reported, and neither have two such molecules in urine been examined in a single study of DN. In this prospective observational study, 43 adult diabetic patients were studied, 40 were followed up for 6years. Urinary MCP-1/creatinine ratios were found to be significantly higher in patients with macroalbuminuria (3.3- and 2.1-fold higher (p<0.01) than normoalbuminuric and microalbuminuric patients, respectively). CCN2 exhibited a pattern different from that of urinary MCP-1. Urinary CCN2/creatinine ratios were greatly elevated in both microalbuminuric and macroalbuminuric patients (125- and 74-fold higher than normoalbuminuric patients, respectively, p<0.01 and p<0.05, respectively). Further, urinary CCN2, but not MCP-1, correlated with progression of microalbuminuria (R=0.49, p<0.05). In contrast, MCP-1, but not CCN2, correlated with the rate of eGFR decline for all patients (R=0.61, p<0.0001), reflective of its predictive value in patients with macroalbuminuria, but not for patients with microalbuminuria or normoalbuminuria. In conclusion, increased urinary CCN2 is associated with the early progression of DN, whereas MCP-1 is associated with later stage disease.

    The pulsed ultraviolet radiation (UVP) has been used as an alternative strategy for the control of microorganisms in food. However, its application causes the browning of minimally processed fruits and vegetables. In order to control the browning of the 'Tommy Atkins' minimally processed mango and treated with UVP (5.7 J cm(-2)) it was used 1-methylcyclopropene (1-MCP) (0.5 μL L(-1)), an ethylene action blocker in separate stages, comprising five treatments: control, UVP (U), 1-MCP + UVP (M + U), UVP + 1-MCP (U + M) e 1-MCP + UVP + 1-MCP (M + U + M). At the 1st, 7th and 14th days of storage at 12 °C, we evaluated the color (L* and b*), electrolyte leakage, polyphenol oxidase, total extractable polyphenols, vitamin C and total antioxidant activity. The 1-MCP, when applied before UVP, prevented the loss of vitamin C and when applied in a double dose, retained the yellow color (b*) of the cubes. However, the 1-MCP reduced lightness (L*) of independent mango cubes whatever applied before and/or after the UVP. Thus, the application of 1-MCP did not control, but intensified the browning of minimally processed mangoes irradiated with UVP.

    The traditional definition of climacteric and non-climacteric fruits has been put into question. A significant example of this paradox is the climacteric fig fruit. Surprisingly, ripening-related ethylene production increases following pre- or postharvest 1-methylcyclopropene (1-MCP) application in an unexpected auto-inhibitory manner. In this study, ethylene production and the expression of potential ripening-regulator, ethylene-synthesis, and signal-transduction genes are characterized in figs ripening on the tree and following preharvest 1-MCP application. Fig ripening-related gene expression was similar to that in tomato and apple during ripening on the tree, but only in the fig inflorescence-drupelet section. Because the pattern in the receptacle is different for most of the genes, the fig drupelets developed inside the syconium are proposed to function as parthenocarpic true fruit, regulating ripening processes for the whole accessory fruit. Transcription of a potential ripening regulator, FcMADS8, increased during ripening on the tree and was inhibited following 1-MCP treatment. Expression patterns of the ethylene-synthesis genes FcACS2, FcACS4, and FcACO3 could be related to the auto-inhibition reaction of ethylene production in 1-MCP-treated fruit. Along with FcMADS8 suppression, gene expression analysis revealed upregulation of FcEBF1, and downregulation of FcEIL3 and several FcERFs by 1-MCP treatment. This corresponded with the high storability of the treated fruit. One FcERF was overexpressed in the 1-MCP-treated fruit, and did not share the increasing pattern of most FcERFs in the tree-ripened fig. This demonstrates the potential of this downstream ethylene-signal-transduction component as an ethylene-synthesis regulator, responsible for the non-climacteric auto-inhibition of ethylene production in fig.

    The effect of the complex relationship between ethylene and abscisic acid (ABA) on flower development and senescence in Hibiscus rosa-sinensis L. was investigated. Ethylene biosynthetic (HrsACS and HrsACO) and receptor (HrsETR and HrsERS) genes were isolated and their expression evaluated in three different floral tissues (petals, style-stigma plus stamens, and ovaries) of detached buds and open flowers. This was achieved through treatment with 0.1 mM 1-aminocyclopropane-1-carboxylic acid (ACC) solution, 500 nl l(-1) methylcyclopropene (1-MCP), and 0.1 mM ABA solution. Treatment with ACC and 1-MCP confirmed that flower senescence in hibiscus is ethylene dependent, and treatment with exogenous ABA suggested that ABA may play a role in this process. The 1-MCP impeded petal in-rolling and decreased ABA content in detached open flowers after 9 h. This was preceded by an earlier and sequential increase in ABA content in 1-MCP-treated petals and style-stigma plus stamens between 1 h and 6 h. ACC treatment markedly accelerated flower senescence and increased ethylene production after 6 h and 9 h, particularly in style-stigma plus stamens. Ethylene evolution was positively correlated in these floral tissues with the induction of the gene expression of ethylene biosynthetic and receptor genes. Finally, ABA negatively affected the ethylene biosynthetic pathway and tissue sensitivity in all flower tissues. Transcript abundance of HrsACS, HrsACO, HrsETR, and HrsERS was reduced by exogenous ABA treatment. This research underlines the regulatory effect of ABA on the ethylene biosynthetic and perception machinery at a physiological and molecular level when inhibitors or promoters of senescence are exogenously applied.

    Since IL-8 and MCP-1 are chemoattractant proteins that participate in the recruitment of inflammatory cells into the arthritic joint, we examined the effects of tenidap, a new anti-inflammatory drug of the oxindole family, on IL-8 and MCP-1 expression in the joints of rabbits with acute antigen arthritis. The model was induced by injecting 5 mg/ml ovalbumin into the knees of 20 preimmunized rabbits. Animals were randomized into two groups: treated with tenidap (15 mg/kg per 12 h), or untreated. The effect of tenidap treatment was evaluated on chemokine production in synovial membranes of rabbits with arthritis and in cultured monocytic and synovial cells (SC). By immunoperoxidase staining, chemokines were localized in the synovial tissue. Chemokine messenger RNA levels in the synovial membranes and in cultured cells were analysed by reverse transcription-polymerase chain reaction (RT-PCR). At the end of the study, tenidap significantly reduced neutrophil infiltration into the joint cavity (27 ± 4 × 106 cells/ml versus 45 ± 6 × 106 cells/ml in untreated; P < 0.05), and synovial effusion (134 ± 15 μl versus 236 ± 19 μl in untreated; P < 0.005). Untreated rabbits showed synovial membrane up-regulation in mRNA expression of IL-8 and MCP-1 (11- and seven-fold versus healthy rabbits, respectively) that was markedly decreased by tenidap (two- and three-fold versus healthy rabbits, respectively). IL-8 and MCP-1 were localized in the synovial tissue in a perivascular pattern and areas of the interstitium and lining, mostly coinciding with cell infiltration. Tenidap also reduced the accumulation of IL-8 and MCP-1 proteins. In cultured synovial and monocytic cells, tumour necrosis factor-alpha (TNF-α) elicited an increase in gene expression of IL-8 (four- and nine-fold, respectively) and MCP-1 (nine- and four-fold, respectively) that was significantly reversed in both cell types by 10 μm tenidap. These results suggest that the beneficial effect of tenidap in acute

    The involvement of ethylene response factor (ERF) transcription factor (TF) in the transcriptional regulation of ethylene biosynthesis genes during fruit ripening remains largely unclear. In this study, 15 ERF genes, designated as MaERF1–MaERF15, were isolated and characterized from banana fruit. These MaERFs were classified into seven of the 12 known ERF families. Subcellular localization showed that MaERF proteins of five different subfamilies preferentially localized to the nucleus. The 15 MaERF genes displayed differential expression patterns and levels in peel and pulp of banana fruit, in association with four different ripening treatments caused by natural, ethylene-induced, 1-methylcyclopropene (1-MCP)-delayed, and combined 1-MCP and ethylene treatments. MaERF9 was upregulated while MaERF11 was downregulated in peel and pulp of banana fruit during ripening or after treatment with ethylene. Furthermore, yeast-one hybrid (Y1H) and transient expression assays showed that the potential repressor MaERF11 bound to MaACS1 and MaACO1 promoters to suppress their activities and that MaERF9 activated MaACO1 promoter activity. Interestingly, protein–protein interaction analysis revealed that MaERF9 and -11 physically interacted with MaACO1. Taken together, these results suggest that MaERFs are involved in banana fruit ripening via transcriptional regulation of or interaction with ethylene biosynthesis genes. PMID:23599278

  14. Reactive oxygen and ethylene are involved in the regulation of regurgitant-induced responses in bean plants.

    Application of regurgitant from Leptinotarsa decemlineata Say on wound surfaces of one wounded leaf of intact bean (Phaseolus vulgaris L.) plants resulted in activation of ethylene biosynthesis followed by an increase of both peroxidase and polyphenol oxidase activity. The aim of the present investigation was to study the source of increased oxidative enzyme activities in regurgitant-treated bean leaves and to determine if hydrogen peroxide and ethylene biosynthesis is responsible for regurgitant-induced amplification of wound responses in bean plants. As the regurgitant contained relative high activities of both peroxidase and polyphenol oxidase, there is a possibility that increased enzyme activities in bean leaves following regurgitant treatment is an artifact of insect-derived enzymes. Localisation experiments and electrophoretic analysis revealed that only part of the increased enzyme activities could be attributed to regurgitant-derived enzymes. Both increase of ethylene production and oxidative enzyme activities depended on protein synthesis. To demonstrate if the increase of oxidative metabolism was ethylene-dependent, seedlings were pretreated with aminooxyacetic acid, an inhibitor of ethylene biosynthesis, and 1-methylcyclopropene (1-MCP), a competitive inhibitor of ethylene action. Increase of both peroxidase and polyphenol oxidase activity in wounded and subsequently regurgitant-treated leaf was abolished by both aminooxyacetic acid and 1-MCP. Inhibitor studies indicated that H2O2 generated through NADPH oxidase and superoxide dismutase is necessary for regurgitant-induced increase of ethylene production and oxidative enzyme activities.

  15. Variations in zonal fruit starch concentrations of apples – a developmental phenomenon or an indication of ripening?

    Patterns of starch hydrolysis in stem, equatorial, and calyx zones of ‘Honeycrisp’ and ‘Empire’ apples (Malus sylvestris (L.) Mill var. domestica (Borkh.) Mansf.) during maturation and ripening, and in ‘Gala’ apples in response to propylene or 1-methylcyclopropene (1-MCP) treatments after harvest, were studied. Differences in zonal starch concentrations were found for ‘Empire’ and ‘Gala’ fruits, but not for ‘Honeycrisp’. During maturation and ripening of ‘Empire’, the concentration of starch was highest in the calyx end and lowest in the stem region. Differences in rates of starch hydrolysis among zones were not detected. ‘Honeycrisp’ and ‘Empire’ had the highest concentration of sorbitol in the calyx region, whereas it was highest in the stem-end region in ‘Gala’. The distribution differences of glucose, fructose, and sucrose were similar in all three cultivars; higher fructose and glucose concentrations in the stem region, and higher sucrose concentrations in the calyx end of the fruit. Postharvest treatment of ‘Gala’ with propylene did not affect the internal ethylene concentration of the fruit but 1-MCP markedly inhibited it. Starch concentrations were highest in the calyx end but gradients of starch among zones were not changed by postharvest treatment. The rate of hydrolysis was slowed by 1-MCP treatment, but was unaffected by propylene. Postharvest treatments influenced sorbitol, glucose, and fructose concentrations. Patterns of starch concentration among the zones did not confirm differences in ripening, but reflected its uneven distribution throughout the fruit during development. Therefore, measured differences in zonal starch are most likely related to starch accumulation during fruit development, rather than differences in rates of starch degradation during ripening.

    In vivo changes in the cytosolic pH of abscission zone (AZ) cells were visualized using confocal microscopic detection of the fluorescent pH-sensitive and intracellularly trapped dye, 2’,7’-bis-(2-carboxyethyl)-5(and-6)-carboxyfluorescein (BCECF), driven by its acetoxymethyl ester. A specific and gradual increase in the cytosolic pH of AZ cells was observed during natural abscission of flower organs in Arabidopsis thaliana and wild rocket (Diplotaxis tenuifolia), and during flower pedicel abscission induced by flower removal in tomato (Solanum lycopersicum Mill). The alkalization pattern in the first two species paralleled the acceleration or inhibition of flower organ abscission induced by ethylene or its inhibitor 1-methylcyclopropene (1-MCP), respectively. Similarly, 1-MCP pre-treatment of tomato inflorescence explants abolished the pH increase in AZ cells and pedicel abscission induced by flower removal. Examination of the pH changes in the AZ cells of Arabidopsis mutants defective in both ethylene-induced (ctr1, ein2, eto4) and ethylene-independent (ida, nev7, dab5) abscission pathways confirmed these results. The data indicate that the pH changes in the AZ cells are part of both the ethylene-sensitive and -insensitive abscission pathways, and occur concomitantly with the execution of organ abscission. pH can affect enzymatic activities and/or act as a signal for gene expression. Changes in pH during abscission could occur via regulation of transporters in AZ cells, which might affect cytosolic pH. Indeed, four genes associated with pH regulation, vacuolar H+-ATPase, putative high-affinity nitrate transporter, and two GTP-binding proteins, were specifically up-regulated in tomato flower AZ following abscission induction, and 1-MCP reduced or abolished the increased expression.

  4. Temperature and ultra low oxygen effects and involvement of ethylene in chilling injury of 'Rojo Brillante' persimmon fruit.

    The effects of storage temperature, inhibition of ethylene action by treatment with 1-methylcyclopropene (1-MCP) and ultra low oxygen (ULO) atmosphere on chilling injury (CI), fruit firmness and ethylene production in the astringent 'Rojo Brillante' persimmon fruit were investigated. CI symptoms were manifested as a very dramatic loss of firmness after fruit transfer from cold storage to shelf-life conditions (18 °C). During cold storage, fruit softening appeared more rapidly in fruit stored at the intermediate temperature of 10 °C than at 1 °C or 14.5 °C. Ethylene production increased with storage time at the chilling temperature (1 °C) but a sharp increase took place upon fruit transfer from 1 °C to ambient temperature. This ethylene increase was accompanied by a loss of fruit firmness associated with chilling damage development. A pre-treatment with the competitive inhibitor of ethylene action 1-MCP, at 1 μL/L, reduced firmness loss and mitigated CI damage but considerably increased ethylene production in fruit transferred to shelf-life conditions after a prolonged cold storage period. Collectively, these results suggest a role of ethylene in the reduction of flesh firmness and consequently in the induction of CI in persimmon fruit. Moreover, ethylene exerts a negative feedback regulation of cold-induced ethylene biosynthesis. Storage of 'Rojo Brillante' persimmon fruit under ULO (1.3-1.8% O₂, v/v) atmosphere did not affect the incidence of CI but reduced fruit astringency, suggesting that ULO may be an alternative postharvest storage system for 'Rojo Brillante' persimmon fruit.

  5. The role of alternative oxidase in tomato fruit ripening and its regulatory interaction with ethylene.

    Although the alternative oxidase (AOX) has been proposed to play a role in fruit development, the function of AOX in fruit ripening is unclear. To gain further insight into the role of AOX in tomato fruit ripening, transgenic tomato plants 35S-AOX1a and 35S-AOX-RNAi were generated. Tomato plants with reduced LeAOX levels exhibited retarded ripening; reduced carotenoids, respiration, and ethylene production; and the down-regulation of ripening-associated genes. Moreover, no apparent respiratory climacteric occurred in the AOX-reduced tomato fruit, indicating that AOX might play an important role in climacteric respiration. In contrast, the fruit that overexpressed LeAOX1a accumulated more lycopene, though they displayed a similar pattern of ripening to wild-type fruit. Ethylene application promoted fruit ripening and anticipated ethylene production and respiration, including the alternative pathway respiration. Interestingly, the transgenic plants with reduced LeAOX levels failed to ripen after 1-methylcyclopropene (1-MCP) treatment, while such inhibition was notably less effective in 35S-AOX1a fruit. These findings indicate that AOX is involved in respiratory climacteric and ethylene-mediated fruit ripening of tomato.

    We studied the expression of a gene encoding an ethylene receptor, called Ethylene Response Sensor 1 (Den-ERS1), in the petals of Dendrobium orchid flowers. Transcripts accumulated during the young floral bud stage and declined by the time the flowers had been open for several days. Pollination or exposure to exogenous ethylene resulted in earlier flower senescence, an increase in ethylene production and a lower Den-ERS1 transcript abundance. Treatment with 1-methylcyclopropene (1-MCP), an inhibitor of the ethylene receptor, decreased ethylene production and resulted in high transcript abundance. The literature indicates two kinds of ethylene receptor genes with regard to the effects of ethylene. One group shows ethylene-induced down-regulated transcription, while the other has ethylene-induced up-regulation. The present gene is an example of the first group. The 5' flanking region showed binding sites for Myb and myb-like, homeodomain, MADS domain, NAC, TCP, bHLH and EIN3-like transcription factors. The binding site for the EIN3-like factor might explain the ethylene effect on transcription. A few other transcription factors (RAV1 and NAC) seem also related to ethylene effects.

    The chilling conditions of apple cold storage can provoke an economically significant necrotic peel disorder called superficial scald (scald) in susceptible cultivars. Disorder development can be reduced by inhibiting ethylene action or oxidative stress as well as intermittent warming. It was previously demonstrated that scald is preceded by a metabolomic shift that results in altered levels of various classes of triterpenoids, including metabolites with mass spectral features similar to β-sitosterol. In this study, a key class of phytosterol metabolites was identified. Changes in peel tissue levels of conjugates of β-sitosterol and campesterol, including acylated steryl glycosides (ASG), steryl glycosides (SG) and steryl esters (SE), as well as free sterols (FS), were determined during the period of scald development. Responses to pre-storage treatment with the ethylene action inhibitor, 1-methylcyclopropene, or an antioxidant (diphenylamine), rapid temperature elevation, and cold acclimation using intermittent warming treatments were evaluated. Diphenylamine, 1-MCP, and intermittent warming all reduced or prevented scald development. ASG levels increased and SE levels decreased in untreated control fruit during storage. Removing fruit from cold storage to ambient temperature induced rapid shifts in ASG and SE fatty acyl moieties from unsaturated to saturated. FS and SG levels remained relatively stable during storage but SG levels increased following a temperature increase after storage. ASG, SE, and SG levels did not increase during 6 months cold storage in fruit subjected to intermittent warming treatment. Overall, the results show that apple peel phytosteryl conjugate metabolism is influenced by storage duration, oxidative stress, ethylene action/ripening, and storage temperature.

    Fruit set in angiosperms marks the transition from flowering to fruit production and a commitment to seed dispersal. Studies with Solanum lycopersicum (tomato) fruit have shown that pollination and subsequent fertilization induce the biosynthesis of several hormones, including auxin and gibberellins (GAs), which stimulate fruit set. Circumstantial evidence suggests that the gaseous hormone ethylene may also influence fruit set, but this has yet to be substantiated with molecular or mechanistic data. Here, we examined fruit set at the biochemical and genetic levels, using hormone and inhibitor treatments, and mutants that affect auxin or ethylene signaling. The expression of system-1 ethylene biosynthetic genes and the production of ethylene decreased during pollination-dependent fruit set in wild-type tomato and during pollination-independent fruit set in the auxin hypersensitive mutant iaa9-3. Blocking ethylene perception in emasculated flowers, using either the ethylene-insensitive Sletr1-1 mutation or 1-methylcyclopropene (1-MCP), resulted in elongated parthenocarpic fruit and increased cell expansion, whereas simultaneous treatment with the GA biosynthesis inhibitor paclobutrazol (PAC) inhibited parthenocarpy. Additionally, the application of the ethylene precursor 1-aminocyclopropane-1-carboxylic acid (ACC) to pollinated ovaries reduced fruit set. Furthermore, Sletr1-1 parthenocarpic fruits did not exhibit increased auxin accumulation, but rather had elevated levels of bioactive GAs, most likely reflecting an increase in transcripts encoding the GA-biosynthetic enzyme SlGA20ox3, as well as a reduction in the levels of transcripts encoding the GA-inactivating enzymes SlGA2ox4 and SlGA2ox5. Taken together, our results suggest that ethylene plays a role in tomato fruit set by suppressing GA metabolism.

    Apples are predominantly stored in controlled atmosphere (CA) storage to delay ripening and prolong their storage life. Profiling the dynamics of metabolic changes during ripening and CA storage is vital for understanding the governing molecular mechanism. In this study, the dynamics of the primary metabolism of 'Jonagold' apples during ripening in regular air (RA) storage and initiation of CA storage was profiled. 1-Methylcyclopropene (1-MCP) was exploited to block ethylene receptors and to get insight into ethylene mediated metabolic changes during ripening of the fruit and in response to hypoxic stress. Metabolic changes were quantified in glycolysis, the tricarboxylic acid (TCA) cycle, the Yang cycle and synthesis of the main amino acids branching from these metabolic pathways. Partial least square discriminant analysis of the metabolic profiles of 1-MCP treated and control apples revealed a metabolic divergence in ethylene, organic acid, sugar and amino acid metabolism. During RA storage at 18°C, most amino acids were higher in 1-MCP treated apples, whereas 1-aminocyclopropane-1-carboxylic acid (ACC) was higher in the control apples. The initial response of the fruit to CA initiation was accompanied by an increase of alanine, succinate and glutamate, but a decline in aspartate. Furthermore, alanine and succinate accumulated to higher levels in control apples than 1-MCP treated apples. The observed metabolic changes in these interlinked metabolites may indicate a coordinated adaptive strategy to maximize energy production.

    To investigate the regulation of 14-3-3 proteins in banana (Musa acuminata L. AAA group, cv. Brazilian) fruit postharvest ripening, four cDNAs encoding 14-3-3 proteins were isolated from banana and designated as Ma-14-3-3a, Ma-14-3-3c, Ma-14-3-3e, and Ma-14-3-3i, respectively. Amino acid sequence alignment showed that the four 14-3-3 proteins shared a highly conserved core structure and variable C-terminal as well as N-terminal regions with 14-3-3 proteins from other plant species. Phylogenetic analysis revealed that the four 14-3-3 genes belong to the non-ε groups. They were differentially and specifically expressed in various tissues. Real-time RT-PCR analysis indicated that these four genes function differentially during banana fruit postharvest ripening. Three genes, Ma-14-3-3a, Ma-14-3-3c, and Ma-14-3-3e, were significantly induced by exogenous ethylene treatment. However, gene function differed in naturally ripened fruits. Ethylene could induce Ma-14-3-3c expression during postharvest ripening, but expression patterns of Ma-14-3-3a and Ma-14-3-3e suggest that these two genes appear to be involved in regulating ethylene biosynthesis during fruit ripening. No obvious relationship emerged between Ma-14-3-3i expression in naturally ripened and 1-MCP (1-methylcyclopropene)-treated fruit groups during fruit ripening. These results indicate that the 14-3-3 proteins might be involved in various regulatory processes of banana fruit ripening. Further studies will mainly focus on revealing the detailed biological mechanisms of these four 14-3-3 genes in regulating banana fruit postharvest ripening.

    Japanese plums are classified as climacteric; however, some economically important cultivars selected in California produce very little ethylene and require long ripening both “on” and “off” the tree to reach eating-ripe firmness. To unravel the ripening behavior of different Japanese plum cultivars, ripening was examined in the absence (air) or in the presence of ethylene or propylene (an ethylene analog) following a treatment or not with 1-methylcyclopropene (1-MCP, an ethylene action inhibitor). Detailed physiological studies revealed for the first time three distinct ripening types in plum fruit: climacteric, suppressed-climacteric, and non-climacteric. Responding to exogenous ethylene or propylene, the slow-softening supressed-climacteric cultivars produced detectable amounts of ethylene, in contrast to the novel non-climacteric cultivar that produced no ethylene and softened extremely slowly. Genetic analysis using microsatellite markers produced identical DNA profiles for the climacteric cultivars “Santa Rosa” and “July Santa Rosa,” the suppressed-climacteric cultivars “Late Santa Rosa,” “Casselman,” and “Roysum” and the novel non-climacteric “Sweet Miriam,” as expected since historic records present most of these cultivars as bud-sport mutations derived initially from “Santa Rosa.” This present study provides a novel fruit system to address the molecular basis of ripening and to develop markers that assist breeders in providing high-quality stone fruit cultivars that can remain “on-tree,” increasing fruit flavor, saving harvesting costs, and potentially reducing the need for low-temperature storage during postharvest handling.

    The plant-specific NAC (NAM, ATAF1/2, and CUC2) transcription factors (TFs) play important roles in plant growth, development, and stress responses. However, the precise role of NAC TFs in relation to fruit ripening is poorly understood. In this study, six NAC genes, designated MaNAC1–MaNAC6, were isolated and characterized from banana fruit. Subcellular localization showed that MaNAC1–MaNAC5 proteins localized preferentially to the nucleus, while MaNAC6 was distributed throughout the entire cell. A transactivation assay in yeast demonstrated that MaNAC4 and MaNAC6, as well as their C-terminal regions, possessed trans-activation activity. Gene expression profiles in fruit with four different ripening characteristics, including natural, ethylene-induced, 1-methylcyclopropene (1-MCP)-delayed, and a combination of 1-MCP with ethylene treatment, revealed that the MaNAC genes were differentially expressed in peel and pulp during post-harvest ripening. MaNAC1 and MaNAC2 were apparently upregulated by ethylene in peel and pulp, consistent with the increase in ethylene production. In contrast, MaNAC3 in peel and pulp and MaNAC5 in peel were constitutively expressed, and transcripts of MaNAC4 in peel and pulp and MaNAC6 in peel decreased, while MaNAC5 or MaNAC6 in pulp increased slightly during fruit ripening. Furthermore, the MaNAC2 promoter was activated after ethylene application, further enhancing the involvement of MaNAC2 in fruit ripening. More importantly, yeast two-hybrid and bimolecular fluorescence complementation analyses confirmed that MaNAC1/2 physically interacted with a downstream component of ethylene signalling, ethylene insensitive 3 (EIN3)-like protein, termed MaEIL5, which was downregulated during ripening. Taken together, these results suggest that MaNACs such as MaNAC1/MaNAC2, may be involved in banana fruit ripening via interaction with ethylene signalling components. PMID:22888129

    Ethylene has impact on several physiological plant processes, including abscission, during which plants shed both their vegetative and reproductive organs. Cell separation and programmed cell death are involved in abscission, and these have also been correlated with ethylene action. However, the detailed spatiotemporal pattern of the molecular events during abscission remains unknown. We examined the expression of two tomato ACO genes, LeACO1, and LeACO4 that encode the last enzyme in ethylene biosynthesis, 1-aminocyclopropane-1-carboxylate oxidase (ACO), together with the expression of other abscission-associated genes involved in cell separation and programmed cell death, during a period of 0–12 h after abscission induction in the tomato flower pedicel abscission zone and nearby tissues. In addition, we determined their localization in specific cell layers of the flower pedicel abscission zone and nearby tissues obtained by laser microdissection before and 8 h after abscission induction. The expression of both ACO genes was localized to the vascular tissues in the pedicel. While LeACO4 was more uniformly expressed in all examined cell layers, the main expression site of LeACO1 was in cell layers just outside the abscission zone in its proximal and distal part. We showed that after abscission induction, ACO1 protein was synthesized in phloem companion cells, in which it was localized mainly in the cytoplasm. Samples were additionally treated with 1-methylcyclopropene (1-MCP), a competitive inhibitor of ethylene actions, and analyzed 8 h after abscission induction. Cell-layer-specific changes in gene expression were observed together with the specific localization and ethylene sensitivity of the hallmarks of cell separation and programmed cell death. While treatment with 1-MCP prevented separation of cells through inhibition of the expression of polygalacturonases, which are the key enzymes involved in degradation of the middle lamella, this had less impact on

    In this work, the effect of ethylene on flower opening of cut rose (Rosa hybrida) cv. Samantha was studied. However, although ethylene hastened the process of flower opening, 1-MCP (1-methylcyclopropene), an ethylene action inhibitor, impeded it. Ethylene promoted ethylene production in petals, but 1-MCP did not inhibit this process. Of the four ethylene biosynthetic genes tested, Rh-ACS1 and Rh-ACS2 were undetectable; Rh-ACS3 and Rh-ACO1 expression was enhanced by ethylene slightly and greatly, respectively. However, their mRNA amounts were not inhibited by 1-MCP compared with controls. Expression of seven signalling component genes was also studied, including three ethylene receptors (Rh-ETR1, Rh-ETR3, and Rh-ETR5), two CTRs (Rh-CTR1 and Rh-CTR2), and two transcription factors (Rh-EIN3-1 and Rh-EIN3-2). Transcripts of Rh-ETR5, Rh-EIN3-1, and Rh-EIN3-2 were accumulated in a constitutive manner and had no or little response to ethylene or 1-MCP, while transcript levels of Rh-ETR1 and Rh-CTR1 were substantially elevated by ethylene, and those of Rh-ETR3 and Rh-CTR2 were greatly enhanced by ethylene; 1-MCP reduced all the four genes to levels much less than those in control flowers. These results show that ethylene triggers physiological responses related to flower opening in cut rose cv. Samantha, and that continued ethylene perception results in flower opening. Ethylene may regulate flower opening mainly through expression of two ethylene receptor genes (Rh-ETR1 and Rh-ETR3) and two CTR (Rh-CTR1 and Rh-CTR2) genes.

    Novel antimicrobials and new approaches to developing them are urgently needed. Repurposing already-approved drugs with well-characterized toxicology and pharmacology is a novel way to reduce the time, cost, and risk associated with antibiotic innovation. Ebselen, an organoselenium compound, is known to be clinically safe and has a well-known pharmacology profile. It has shown potent bactericidal activity against multidrug-resistant clinical isolates of staphylococcus aureus, including methicillin- and vancomycin-resistant S. aureus (MRSA and VRSA). We demonstrated that ebselen acts through inhibition of protein synthesis and subsequently inhibited toxin production in MRSA. Additionally, ebselen was remarkably active and significantly reduced established staphylococcal biofilms. The therapeutic efficacy of ebselen was evaluated in a mouse model of staphylococcal skin infections. Ebselen 1% and 2% significantly reduced the bacterial load and the levels of the pro-inflammatory cytokines tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-1 beta (IL-1β), and monocyte chemo attractant protein-1 (MCP-1) in MRSA USA300 skin lesions. Furthermore, it acts synergistically with traditional antimicrobials. This study provides evidence that ebselen has great potential for topical treatment of MRSA skin infections and lays the foundation for further analysis and development of ebselen as a potential treatment for multidrug-resistant staphylococcal infections.

    Due to its organoleptic and nutraceutical qualities, strawberry fruit (Fragaria x ananassa, Duch) is a worldwide important commodity. The role of ethylene in the regulation of strawberry cell wall metabolism was studied in fruit from Toyonoka cultivar harvested at white stage, when most changes associated with fruit ripening have begun. Fruit were treated with ethephon, an ethylene-releasing reagent, or with 1-methylcyclopropene (1-MCP), a competitive inhibitor of ethylene action, maintaining a set of non-treated fruit as controls for each condition. Ethephon treated-fruit showed higher contents of hemicelluloses, cellulose and neutral sugars regarding controls, while 1-MCP-treated fruit showed a lower amount of those fractions. On the other hand, ethephon-treated fruit presented a lower quantity of galacturonic acid from ionically and covalently bound pectins regarding controls, while 1-MCP-treated fruit showed higher contents of those components. We also explored the ethylene effect over the mRNA accumulation of genes related to pectins and hemicelluloses metabolism, and a relationship between gene expression patterns and cell wall polysaccharides contents was shown. Moreover, we detected that strawberry necrotrophic pathogens growth more easily on plates containing cell walls from ethephon-treated fruit regarding controls, while a lower growth rate was observed when cell walls from 1-MCP treated fruit were used as the only carbon source, suggesting an effect of ethylene on cell wall structure. Around 60% of strawberry cell wall is made up of pectins, which in turns is 70% made by homogalacturonans. Our findings support the idea of a central role for pectins on strawberry fruit softening and a participation of ethylene in the regulation of this process.

  20. Impact of suppression of ethylene action or biosynthesis on flavor metabolites in apple (Malus domestica Borkh) fruits.

    2004-09-08

    To understand the role of ethylene in regulating the overall flavor of apple fruits, ethylene production or action was reduced using transgenic apple trees suppressed for ACC-synthase or ACC-oxidase enzyme activity or by the addition of 1-methylcyclopropene (1-MCP), an ethylene action inhibitor. Flavor components were differentially regulated in response to the suppression of both ethylene biosynthesis and action. Headspace analysis of aroma production, an ethylene-associated event, showed a reduction in ester and alcohol production in the ethylene-suppressed lines and in the apples treated with 1 microL L(-1) 1-MCP for 20 h at 20 degrees C. However, no major differences were observed in the concentrations of aldehyde volatiles. Other flavor metabolites that showed an ethylene-dependent pattern were organic acids and sugars. Malic acid degradation was significantly reduced under ethylene-suppressed conditions, showing a recovery after the fruit was exposed to ethylene. Sucrose and fructose concentrations were influenced by suppression or enhancement of ethylene. Total phenolics as well as individual phenolic compounds showed an ethylene-dependent regulation only in response to the suppression of ethylene biosynthesis, but not when ethylene action was inhibited.

    The role of ethylene in induction of aerenchyma formation and ethanolic fermentation in waterlogged roots of Dendranthema zawadskii and D. nankingense, two species that differ with respect to waterlogging tolerance, was examined. In the more tolerant D. zawadskii, but not in D. nankingense, ethylene accelerated programmed cell death and promoted formation of lysigenous aerenchyma, both of which were inhibited by treatment with the ethylene inhibitor 1-methylcyclopropene. Waterlogged D. zawadskii roots generated a higher quantity of endogenous ethylene than did those of D. nankingense. In waterlogged D. zawadskii roots, transcription of the genes encoding alcohol dehydrogenase (EC 1.1.1.1) and pyruvate decarboxylase (EC 4.1.1.1) increased rapidly but transiently, whereas expression of these genes in D. nankingense increased gradually and over a longer period. In D. nankingense, waterlogging elevated both alcohol dehydrogenase and pyruvate decarboxylase activity, and the production of ethanol and acetaldehyde was increased in the presence of exogenous ethylene and inhibited by 1-methylcyclopropene. In D. zawadskii, in contrast, after a prolonged episode of waterlogging stress, exogenous supply of ethylene suppressed the production of ethanol and acetaldehyde, whereas exogenous 1-methylcyclopropene enhanced their production. In the more tolerant Dendranthema species, ethylene appeared to signal an acceleration of both waterlogging-induced programmed cell death and aerenchyma formation and to alleviate ethanolic fermentation, whereas in the more sensitive species ethylene activated fermentation and increased the release of ethanol and acetaldehyde, which are by-products probably responsible for the collapse of the waterlogging-damaged root.

    Background Persistent inflammation and immune activation has been hypothesized to contribute to increased prevalence of subclinical atherosclerosis and cardiovascular disease (CVD) risk in patients with chronic HIV infection. In this study, we examined the correlation of peripheral monocyte subsets and soluble biomarkers of inflammation to coronary artery calcium (CAC) progression, as measured by cardiac computed tomography scan. Methods We conducted a longitudinal analysis utilizing baseline data of 78 participants with HIV infection on stable antiretroviral therapy (ART) in the Hawaii Aging with HIV-Cardiovascular study who had available baseline monocyte subset analysis as well as CAC measurement at baseline and at 2-year follow up. Monocyte phenotypes were assessed from cryopreserved blood by flow cytometry and plasma was assayed for soluble biomarkers using antibody-coated beads in a high sensitivity Milliplex Luminex platform. Change in CAC over 2 years was analyzed as the primary outcome variable. Results Of all monocyte subsets and biomarkers tested, higher non-classical monocyte percentage (ρ = 0.259, p = 0.022), interleukin (IL)-6 (ρ = 0.311, p = 0.012), and monocyte chemoattractant protein (MCP)-1 (ρ = 0.524, p = <0.001) were significantly correlated to higher 2-year CAC progression in unadjusted Spearman’s correlation. Non-classical monocyte percentage (ρ = 0.247, p = 0.039), and MCP-1 (ρ = 0.487, p = <0.001), remained significantly correlated to 2-year CAC progression, while IL-6 was not (ρ = 0.209, p = 0.120) after adjustment for age, hypertension, diabetes mellitus, total/HDL cholesterol ratio, smoking history, and BMI. Conclusion The percentage of non-classical monocytes and plasma MCP-1 levels were independently associated with CAC progression and may be related to the progression of atherosclerosis and increased CVD risk associated with chronic HIV infection on stable ART.

    Background T-cells extravasation and CNS parenchyma infiltration during autoimmune neurodegenerative disease can be evoked by local antigen presenting cells. Studying the chemoattracting potential of spinal perivascular macrophages (SPM) during experimental allergic encephalomyelitis (EAE), we observed numerous infiltrates of densely-packed mononuclear cells. Apart from the poor spatial and optical resolution, no differentiation between the resident SPM (mabs ED1+, ED2+) and the just recruited monocytes/macrophages (mab ED1+) was possible. Results This is why we labeled SPM by injections of different fluoresecent dyes into the lateral cerebral ventricle before induction of active EAE. Within an additional experimental set EAE was induced by an intraperitoneal injection of T-cells specifically sensitized to myelin basic protein (MBP) and engineered to express the green fluorescent protein (GFP). In both experiments we observed a strong activation of SPM (mabs OX6+, SILK6+, CD40+, CD80+, CD86+) which was accompanied by a consistently increased expression of ICAM-1, VCAM-1, and the chemokines MCP-1 and MIP-1α. Conclusion These observations indicate that SPM play a role in promoting lymphocyte extravasation. PMID:12196270

    Liver fibrosis is one of the common complications of transient myeloproliferative disorder (TMD) in Down syndrome (DS), but the exact molecular pathogenesis is largely unknown. We herein report a neonate of DS with liver fibrosis associated with TMD, in which we performed the serial profibrogenic cytokines analyses. We found the active monocyte chemoattractant protein-1 expression in the affected liver tissue and also found that both serum and urinary monocyte chemoattractant protein-1 concentrations are noninvasive biomarkers of liver fibrosis. We also showed a prospective of the future anticytokine therapy with herbal medicine for the liver fibrosis associated with TMD in DS.

    Recent studies have demonstrated an essential role of alveolar macrophages during influenza virus infection. Enhanced mortalities were observed in macrophage-depleted mice and pigs after influenza virus infection, but the basis for the enhanced pathogenesis is unclear. This study revealed that blocking macrophage recruitment into the lungs in a mouse model of influenza pneumonitis resulted in enhanced alveolar epithelial damage and apoptosis, as evaluated by histopathology, immunohistochemistry, Western blot, RT-PCR, and TUNEL assays. Abrogation of macrophage recruitment was achieved by treatment with monoclonal antibody against monocyte chemoattractant protein-1 (MCP-1) after sub-lethal challenge with mouse-adapted human influenza A/Aichi/2/68 virus. Interestingly, elevated levels of hepatocyte growth factor (HGF), a mitogen for alveolar epithelium, were detected in bronchoalveolar lavage samples and in lung homogenates of control untreated and nonimmune immunoglobulin (Ig)G-treated mice after infection compared with anti-MCP-1-treated infected mice. The lungs of control animals also displayed strongly positive HGF staining in alveolar macrophages as well as alveolar epithelial cell hyperplasia. Co-culture of influenza virus-infected alveolar epithelial cells with freshly isolated alveolar macrophages induced HGF production and phagocytic activity of macrophages. Recombinant HGF added to mouse lung explants after influenza virus infection resulted in enhanced BrdU labeling of alveolar type II epithelial cells, indicating their proliferation, in contrast with anti-HGF treatment showing significantly reduced epithelial regeneration. Our data indicate that inhibition of macrophage recruitment augmented alveolar epithelial damage and apoptosis during influenza pneumonitis, and that HGF produced by macrophages in response to influenza participates in the resolution of alveolar epithelium.

    Fruits from many citrus cultivars develop depressed areas in the flavedo (outer part of the peel) and albedo (inner part) following detachment. Although ultrastructural analysis may provide important information about multiple plant responses to stresses and external stimuli at the cell and tissue levels, and despite the proved efficacy of ethylene in reducing peel damage in citrus fruit, cytological responses of this horticultural crop to protective ethylene concentrations have not yet been reported. We show that applying high ethylene levels (2 μL L(-1) for 14 days) causes sublethal stress as it favored the alteration of cuticle, vacuole, middle lamella and primary wall, especially in the albedo cells, but reduced peel collapse in detached mature "Navelate" oranges (C. sinensis, L. Osbeck) held under nonstressful environmental conditions (22°C and 90-95% RH). Ethylene did not induce relevant changes in lignification but favored the deposition of pectic exudates and the release of sugars from degradation of cell polysaccharides including starch, cellulose, and pectins. In contrast, inhibiting ethylene perception by applying 1-methylcyclopropene (1-MCP) reduced these ethylene-related responses and favored degradation of cell membranes and peel damage. The overall results reflect that mature oranges tolerate high ethylene levels that might favor the activation of defense responses involving oxidative-stress related mechanisms and recycling of nutrients and carbon supply to enable cells to sustain respiration and cope with carbon deprivation stress caused by detachment.

    The ovate family protein named MaOFP1 was identified in banana (Musa acuminata L.AAA) fruit by a yeast two-hybrid (Y2H) method using the banana MADS-box gene MuMADS1 as bait and a 2 day postharvest (DPH) banana fruit cDNA library as prey. The interaction between MuMADS1 and MaOFP1 was further confirmed by Y2H and Bimolecular Fluorescence Complementation (BiFC) methods, which showed that the MuMADS1 K domain interacted with MaOFP1. Real-time quantitative PCR evaluation of MuMADS1 and MaOFP1 expression patterns in banana showed that they are highly expressed in 0 DPH fruit, but present in low levels in the stem, which suggests that simultaneous but different expression patterns exist for both MuMADS1 and MaOFP1 in different tissues and developing fruits. Meanwhile, MuMADS1 and MaOFP1 expression was highly stimulated and greatly suppressed, respectively, by exogenous ethylene. In contrast, MaOFP1 expression was highly stimulated while MuMADS1 was greatly suppressed by the ethylene competitor 1-methylcyclopropene (1-MCP). These results indicate that MuMADS1 and MaOFP1 are antagonistically regulated by ethylene and might play important roles in postharvest banana fruit ripening. PMID:25886169

    2013-10-01

    The mechanism of age-induced decreased stomatal sensitivity to abscisic acid (ABA) and soil drying has been explored here. Older, fully expanded leaves partly lost their ability to close stomata in response to foliar ABA sprays, and soil drying which stimulated endogenous ABA production, while young fully expanded leaves closed their stomata more fully. However, ABA- or soil drying-induced stomatal closure of older leaves was partly restored by pretreating plants with 1-methylcyclopropene (1-MCP), which can antagonize ethylene receptors, or by inoculating soil around the roots with the rhizobacterium Variovorax paradoxus 5C-2, which contains 1-aminocyclopropane-1-carboxylic acid (ACC)-deaminase. ACC (the immediate biosynthetic precursor of ethylene) sprays revealed higher sensitivity of stomata to ethylene in older leaves than younger leaves, despite no differences in endogenous ACC concentrations or ethylene emission. Taken together, these results indicate that the relative insensitivity of stomatal closure to ABA and soil drying in older leaves is likely due to altered stomatal sensitivity to ethylene, rather than ethylene production. To our knowledge, this is the first study to mechanistically explain diminished stomatal responses to soil moisture deficit in older leaves, and the associated reduction in leaf water-use efficiency.

However, there are not effective for the treatment of tension-type headache. For the prevention of frequent episodic migraine betablockers, flunarizine, topiramate and amitriptyline are recommended. For the prevention of chronic migraine evidence is only available for onabotulinumtoxinA and topiramate. For prophylactic treatment of tension-type headaches tricyclic antidepressants are used. In cluster headache verapamil (in combination with steroids) is the most frequently used prophylactic agent.

The system consists of a septic tank or tanks for initial sewage processing and a natural secondary treatment facility for further processing of septic tanks' effluent, consisting of a narrow trench, which contains marsh plants and rocks, providing a place for microorganisms. Plants and microorganisms absorb and digest, thus cleansing partially processed wastewater. No odors are evident and cleaned effluent may be discharged into streams or drainage canals. The system is useful in rural areas, costs about $1,900, and requires less maintenance than mechanical systems.

    The inflammatory microenvironment contributes to cancer development and progression. Mesenchymal stem cells (MSCs), as important stromal cells, may be 'educated' by the inflammatory microenvironment to support the development of gastric cancer. Cytokines are a key component of cancer-related inflammation. Interleukin (IL)-6, as an inflammatory cytokine, has multiple roles in cancer. However, whether MSCs can be 'educated' by IL-6 to support gastric cancer remains unknown. In the present study, we focused on the phenotype and function of human umbilical cord-derived MSCs hUC‑MSCs pre-treated with IL-6 in gastric cancer. We found that the protein levels of α-smooth muscle actin (α-SMA) were upregulated, and phosphorylated nuclear factor (NF)-κB protein levels were downregulated in the hUC‑MSCs pre-treated with IL-6, as shown by western blot analysis. The levels of tumor‑promoting cytokines, including chemokine (C-C motif) ligand 5 (CCL5), platelet-derived growth factor‑BB (PDGF‑BB), monocyte chemoattractant protein-1 (MCP-1) and tumor necrosis factor α(TNFα), were markedly reduced in the hUC‑MSCs following treatment with IL-6, as shown by RT-qPCR. In in vitro experiments, we co-cultured MSCs with N-methyl‑N'‑nitro‑N‑nitrosoguanidine (MNNG)‑transformed GES-1 gastric epithelial cells or SGC-7901 gastric cancer cells. Transwell and colony-forming cell assays revealed that the hUC-MSCs significantly promoted gastric cellular migration and proliferation. However, following treatment with IL-6, the hUC-MSCs had no growth-promoting effect on the gastric epithelial cells and gastric cancer cells. In in vivo experiments, we co-transplanted MSCs and SGC-7901 cells into nude mice in order to establish a nude mouse model of gastric cancer. The hUC-MSCs significantly promoted the growth gastric tumors through the promotion of cell proliferation and the inhibition of cell apoptosis. On the contrary, pre-treatment with IL-6 provided the hUC‑MSCs with

    A simple surface treatment process is provided which offers a high performance surface for a variety of applications at low cost. This novel surface treatment, which is particularly useful for Ti-6Al-4V alloys, is achieved by forming oxides on the surface with a two-step chemical process and without mechanical abrasion. First, after solvent degreasing, sulfuric acid is used to generate a fresh titanium surface. Next, an alkaline perborate solution is used to form an oxide on the surface. This acid-followed-by-base treatment is cost effective and relatively safe to use in commercial applications. In addition, it is chromium-free, and has been successfully used with a sol-gel coating to afford a strong adhesive bond that exhibits excellent durability after the bonded specimens have been subjected to a harsh 72 hour water boil immersion. Phenylethynyl containing adhesives were used to evaluate this surface treatment with a novel coupling agent containing both trialkoxysilane and phenylethynyl groups. 8 Claims, 16 Drawing Sheets

    2015-01-01

    SUMMARY Considered to be an emerging endemic mycosis in Latin America, paracoccidioidomycosis is characterized by a chronic course and involvement of multiple organs in immunocompromised hosts. Infection sequelae are mainly related to pulmonary and adrenal insufficiency. The host-parasite interaction results in different expressions of the immune response depending on parasite pathogenicity, fungal load and genetic characteristics of the host. A few controlled and case series reports have shown that azoles and fast-acting sulfa derivatives are useful treatment alternatives in milder forms of the disease. For moderate/severe cases, more prolonged treatments or even parenteral routes are required especially when there is involvement of the digestive tract mucosa, resulting in poor drug absorption. Although comparative studies have reported that shorter treatment regimens with itraconazole are able to induce cure in chronically-infected patients, there are still treatment challenges such as the need for more controlled studies involving acute cases, the search for new drugs and combinations, and the search for compounds capable of modulating the immune response in severe cases as well as the paradoxical reactions.

    The use of antimicrobials is a common practice for preservation of foods. Incorporation, in a food recipe, of chemical antimicrobials towards inhibition of spoilage and pathogenic micro-organisms results in the compositional modification of food. This treatment is nowadays undesirable for the consumer, who likes natural products. Scientific community reflecting consumers demand for natural antimicrobials has made efforts to investigate the possibility to use natural antimicrobials such us bacteriocins and essential oils of plant origin to inhibit microbial growth.

  7. Effect of growth hormone treatment on pancreatic inflammation, oxidative stress, and apoptosis related to aging in SAMP8 mice.

    Aging is associated with an increase in inflammation, oxidative stress, and apoptosis. Furthermore, aging is accompanied by an alteration of the growth hormone (GH) -insulin-like growth factor-1 (IGF-1) axis. The aim of this study was to examine the regulation of these parameters in the pancreas of old mice and how GH treatment could affect this process. Male senescence-accelerated prone mice (SAMP8) and male senescence-accelerated resistant mice (SAMR1) 2 (young) and 10 months old were used (n = 40). Animals were divided into five experimental groups: 1 and 2, SAMP8/R1 young control; 3 and 4, SAMP8/R1 old control (untreated); and 5, SAMP8 old treated with GH. Physiologically equivalent doses of GH were administered for 1 month (2 mg subcutaneously [s.c.]/kg/day) and several parameters were analyzed. Aging was associated with increased inflammation, oxidative stress, and apoptosis (increased tumor necrosis factor-α [TNF-α], interleukin-β [IL-β], IL-6, monocyte chemoattractant protein-1 [MCP1], IL-2, heme oxygenase [HO-1], inducible nitric oxide synthase [iNOS], and nitric oxide metabolites [NOx]). The ratio of anti/pro apoptotic mRNA expression-B cell lymphoma 2 (Bcl-2) Bcl-2-associated X protein (BAX) + Bcl-xL/Bcl-2-associated death promoter (BAD)-was decreased during aging in SAMP8 mice. X-inhibitor of apoptosis (XIAP) was decreased during the aging process. Furthermore, no changes were observed in protein expression of nuclear factor-κB (NF-κB p65 and NF-κBp50-105. However, the protein expression of NF-κB p52-100 and inhibitor kappa B (IκB) alpha was increased with age in the pancreas of SAMP8 mice. On the other hand, the expression of IκB beta was decreased with aging. These results indicate that aging is associated with significant alterations in the relative expression of pancreatic genes involved in inflammation, oxidative stress, and apoptosis. According to our results, GH administration to old SAMP8 mice was able to improve pancreas from

    In the early 1970's, National Space Technology Laboratories discovered that water hyacinths literally thrive on sewage; they absorb and digest nutrients and minerals from wastewater, converting sewage effluents to clean water. They offer a means of purifying water at a fraction of the cost of a conventional sewage treatment plant, and provide a bonus value in byproducts. Hyacinths must be harvested at intervals; the harvested plants are used as fertilizers, high-protein animal feed and a source of energy. Already serving a number of small towns, the "aquaculture" technique has significantly advanced with its adoption by a major U.S. city.

    As for any chronic disease, adherence to osteoporosis treatment is low. Folates and vitamin B12 decrease hip fracture risk in elderly Japanese with stroke. Raloxifene (Evista) decreases the incidence of positive estrogen receptor breast cancer and could prevent cardiovascular events in patients at high risk. Strontium ranelate (Protélos) prevents hip fracture in elderly women. The action of alendronate (Fosamax) on bone mineral density and markers of bone remodelling is of higher amplitude than that of risedronate (Actonel). Once monthly ibandronate (Bonviva) increases bone mineral density in post menopausal women with osteoporosis. Excessive suppression of bone remodelling and osteonecrosis of the yaws could be related to bisphosphonate intake.

  10. S-adenosyl-L-methionine usage during climacteric ripening of tomato in relation to ethylene and polyamine biosynthesis and transmethylation capacity.

    S-adenosyl-L-methionine (SAM) is the major methyl donor in cells and it is also used for the biosynthesis of polyamines and the plant hormone ethylene. During climacteric ripening of tomato (Solanum lycopersicum 'Bonaparte'), ethylene production rises considerably which makes it an ideal object to study SAM involvement. We examined in ripening fruit how a 1-MCP treatment affects SAM usage by the three major SAM-associated pathways. The 1-MCP treatment inhibited autocatalytic ethylene production but did not affect SAM levels. We also observed that 1-(malonylamino)cyclopropane-1-carboxylic acid formation during ripening is ethylene dependent. SAM decarboxylase expression was also found to be upregulated by ethylene. Nonetheless polyamine content was higher in 1-MCP-treated fruit. This leads to the conclusion that the ethylene and polyamine pathway can operate simultaneously. We also observed a higher methylation capacity in 1-MCP-treated fruit. During fruit ripening substantial methylation reactions occur which are gradually inhibited by the methylation product S-adenosyl-L-homocysteine (SAH). SAH accumulation is caused by a drop in adenosine kinase expression, which is not observed in 1-MCP-treated fruit. We can conclude that tomato fruit possesses the capability to simultaneously consume SAM during ripening to ensure a high rate of ethylene and polyamine production and transmethylation reactions. SAM usage during ripening requires a complex cellular regulation mechanism in order to control SAM levels.

  11. Characterisation of ethylene pathway components in non-climacteric capsicum

    PubMed Central

    2013-01-01

    Background Climacteric fruit exhibit high ethylene and respiration levels during ripening but these levels are limited in non-climacteric fruit. Even though capsicum is in the same family as the well-characterised climacteric tomato (Solanaceae), it is non-climacteric and does not ripen normally in response to ethylene or if harvested when mature green. However, ripening progresses normally in capsicum fruit when they are harvested during or after what is called the ‘Breaker stage’. Whether ethylene, and components of the ethylene pathway such as 1-aminocyclopropane 1-carboxylate (ACC) oxidase (ACO), ACC synthase (ACS) and the ethylene receptor (ETR), contribute to non-climacteric ripening in capsicum has not been studied in detail. To elucidate the behaviour of ethylene pathway components in capsicum during ripening, further analysis is therefore needed. The effects of ethylene or inhibitors of ethylene perception, such as 1-methylcyclopropene, on capsicum fruit ripening and the ethylene pathway components may also shed some light on the role of ethylene in non-climacteric ripening. Results The expression of several isoforms of ACO, ACS and ETR were limited during capsicum ripening except one ACO isoform (CaACO4). ACS activity and ACC content were also low in capsicum despite the increase in ACO activity during the onset of ripening. Ethylene did not stimulate capsicum ripening but 1-methylcyclopropene treatment delayed the ripening of Breaker-harvested fruit. Some of the ACO, ACS and ETR isoforms were also differentially expressed upon treatment with ethylene or 1-methylcyclopropene. Conclusions ACS activity may be the rate limiting step in the ethylene pathway of capsicum which restricts ACC content. The differential expression of several ethylene pathway components during ripening and upon ethylene or 1-methylclopropene treatment suggests that the ethylene pathway may be regulated differently in non-climacteric capsicum compared to the climacteric tomato

  13. Characterization of expression, and cloning, of beta-D-xylosidase and alpha-L-arabinofuranosidase in developing and ripening tomato (Lycopersicon esculentum Mill.) fruit.

    PubMed

    Itai, Akihiro; Ishihara, Koji; Bewley, J Derek

    2003-12-01

    Modifications to the cell wall of developing and ripening tomato fruit are mediated by cell wall-degrading enzymes, including a beta-d-xylosidase or alpha-l-arabinofuranosidase, which participate in the breakdown of xylans and/or arabinoxylans. The activity of both enzymes was highest during early fruit growth, before decreasing during later development and ripening. Two beta-d-xylosidase cDNAs, designated LeXYL1 and LeXYL2, and an alpha-l-arabinofuranosidase cDNA, designated LeARF1, were obtained. Accumulation of mRNAs for beta-d-xylosidase and alpha-l-arabinofuranosidase was examined during fruit development and ripening. LeARF1 and LeXYL2 genes were relatively highly expressed during fruit development and decreased after the onset of ripening. By contrast, LeXYL1 was not expressed during fruit development, but was expressed later, particularly during over-ripening. The expression of all three genes was also followed in ripening-impaired mutants, Nr, Nr2, nor, and rin of cv. Ailsa Craig fruit. LeXYL2 mRNA was detected in the ripe fruits of all the mutants and its abundance was similar to that in mature green wild-type fruit. By contrast, LEXYL1 mRNA was expressed only in the ripe fruits of the Nr mutant, suggesting that the two beta-d-xylosidase genes are subject to distinct regulatory control during fruit development and ripening. LeARF1 mRNA was detected in ripe fruits of Nr2, nor and rin, and not in ripe fruit of the Nr mutant. The accumulation of LeARF1 in ripe fruit was restored by 1-methylcyclopropene (1-MCP), an inhibitor of ethylene action, while 1-MCP had no effect on the expression of LeXYL1 or LeXYL2. This suggests that LeARF1 expression is subject to negative regulation by ethylene and that the two beta-d-xylosidase genes are independent of ethylene action.

    Although ethylene is well known as an essential regulator of fruit development, little work has examined the role ethylene plays in the development and maturation of mulberry (Morus L.) fruit. To study the mechanism of ethylene action during fruit development in this species, we measured the ethylene production, fruit firmness, and soluble solids content (SSC) during fruit development and harvest. By comparing the results with those from other climacteric fruit, we concluded that Morus fruit are probably climacteric. Genes associated with the ethylene signal transduction pathway of Morus were characterized from M. notabilis Genome Database, including four ethylene receptor genes, a EIN2-like gene, a CTR1-like gene, four EIN3-like genes, and a RTE1-like gene. The expression patterns of these genes were analyzed in the fruit of M. atropurpurea cv. Jialing No.40. During fruit development, transcript levels of MaETR2, MaERS, MaEIN4, MaRTE, and MaCTR1 were lower at the early stages and higher after 26 days after full bloom (DAF), while MaETR1, MaEIL1, MaEIL2, and MaEIL3 remained constant. In ripening fruit, the transcripts of MaACO1 and MaACS3 increased, while MaACS1 and MaACO2 decreased after harvest. The transcripts of MaACO1, MaACO2, and MaACS3 were inhibited by ethylene, and 1-MCP (1-methylcyclopropene) upregulated MaACS3. The transcripts of the MaETR-like genes, MaRTE, and MaCTR1 were inhibited by ethylene and 1-MCP, suggesting that ethylene may accelerate the decline of MaETRs transcripts. No significant changes in the expression of MaEIN2, MaEIL1, and MaEIL3 were observed during ripening or in response to ethylene, while the expressions of MaEIL2 and MaEIL4 increased rapidly after 24 h after harvest (HAH) and were upregulated by ethylene. The present study provides insights into ethylene biosynthesis and signal transduction in Morus plants and lays a foundation for the further understanding of the mechanisms underlying Morus fruit development and ripening.

  15. Auxin, ethylene and the regulation of root growth under mechanical impedance

    Among the multitude functions performed by plant roots, little information is available about the mechanisms that allow roots to overcome the soil resistance, in order to grow in the soil to obtain water and nutrient. Tomato (Solanum lycopersicum) seedlings grown on horizontally placed agar plates showed a progressive decline in the root length with the increasing impedance of agar media. The incubation with 1-methylcyclopropane (1-MCP), an inhibitor of ethylene perception, led to aerial growth of roots. In contrast, in absence of 1-MCP control roots grew horizontally anchored to the agar surface. Though 1-MCP-treated and control seedlings showed differential ability to penetrate in the agar, the inhibition of root elongation was nearly similar for both treatments. While increased mechanical impedance also progressively impaired hypocotyl elongation in 1-MCP treated seedlings, it did not affect the hypocotyl length of control seedlings. The decline in root elongation was also associated with increased expression of DR5::GUS activity in the root tip signifying accumulation of auxin at the root tip. The increased expression of DR5::GUS activity in the root tip was also observed in 1-MCP treated seedlings, indicating independence of this response from ethylene signaling. Our results indicate operation of a sensing mechanism in root that likely operates independently of ethylene but involves auxin to determine the degree of impedance of the substratum.

  7. An early ethylene up-regulated gene encoding a calmodulin-binding protein involved in plant senescence and death

    Yang, T.; Poovaiah, B. W.

    2000-01-01

    35S-Labeled calmodulin (CaM) was used to screen a tobacco anther cDNA library. A positive clone (NtER1) with high homology to an early ethylene-up-regulated gene (ER66) in tomato, and an Arabidopsis homolog was isolated and characterized. Based on the helical wheel projection, a 25-mer peptide corresponding to the predicted CaM-binding region of NtER1 (amino acids 796-820) was synthesized. The gel-mobility shift assay showed that the peptide formed a stable complex with CaM only in the presence of Ca(2+). CaM binds to NtER1 with high affinity (K(d) approximately 12 nm) in a calcium-dependent manner. Tobacco flowers at different stages of development were treated with ethylene or with 1-methylcyclopropene for 2 h before treating with ethylene. Northern analysis showed that the NtER1 was rapidly induced after 15 min of exposure to ethylene. However, the 2-h 1-methylcyclopropene treatment totally blocked NtER1 expression in flowers at all stages of development, suggesting that NtER1 is an early ethylene-up-regulated gene. The senescing leaves and petals had significantly increased NtER1 induction as compared with young leaves and petals, implying that NtER1 is developmentally regulated and acts as a trigger for senescence and death. This is the first documented evidence for the involvement of Ca(2+)/CaM-mediated signaling in ethylene action.

    Internet addiction (IA) is a prevalent, highly comorbid, and significantly impairing disorder. Although many psychotherapeutic approaches and psychotropic medications have been recommended and some of the psychotherapeutic approaches and a few pharmacotherapy strategies have been studied, treatment of IA is generally in its early stages. This article reviews theoretical descriptions of psychotherapy and the effects of psychosocial treatment and pharmacologic treatment. We also outline our own treatment model of IA.

    Fruit ripening in response to treatments with propylene, 1-methycyclopropene (1-MCP), and low temperature was characterized in ‘Sanuki Gold’ kiwifruit, Actinidia chinensis Planch. Propylene treatment immediately induced rapid fruit softening, increased AC-PG (polygalacturonase) and AC-EXP (expansin) mRNA accumulation, and stimulated an increase in the soluble solid concentration (SSC) and a decrease in titratable acidity (TA). After 3 d exposure to propylene, ethylene production and AC-PL (pectate lyase) mRNA accumulation were observed. 1-MCP treatment after 24 h exposure to propylene eliminated AC-PG mRNA accumulation and suppressed continued changes in SSC and TA. Application of 1-MCP at the start of the treatment, followed by continuous propylene exposure, markedly delayed fruit softening, and the expression of the cell wall-modifying genes, and changes in the SSC and TA, indicating that kiwifruit become insensitive to ethylene at least for 3 d following 1-MCP exposure. Surprisingly, significant fruit softening, mRNA accumulation of AC-PG, AC-PL, and AC-EXP, and decreased TA were observed without ethylene production in intact fruit stored at low temperature for 1 month, but not in fruit stored at room temperature. Repeated 1-MCP treatments (twice a week) failed to inhibit the changes that occurred in low temperature storage. These observations indicate that low temperature modulates the ripening of kiwifruit in an ethylene-independent manner, suggesting that kiwifruit ripening is inducible by either ethylene or low temperature signals.

  14. Treatment of bipolar disorder

    PubMed Central

    2013-01-01

    We review recent developments in the acute and long-term treatment of bipolar disorder and identify promising future routes to therapeutic innovation. Overall, advances in drug treatment remain quite modest. Antipsychotic drugs are effective in the acute treatment of mania; their efficacy in the treatment of depression is variable with the clearest evidence for quetiapine. Despite their widespread use, considerable uncertainty and controversy remains about the use of antidepressant drugs in the management of depressive episodes. Lithium has the strongest evidence for long-term relapse prevention; the evidence for anticonvulsants such as divalproex and lamotrigine is less robust and there is much uncertainty about the longer term benefits of antipsychotics. Substantial progress has been made in the development and assessment of adjunctive psychosocial interventions. Long-term maintenance and possibly acute stabilisation of depression can be enhanced by the combination of psychosocial treatments with drugs. The development of future treatments should consider both the neurobiological and psychosocial mechanisms underlying the disorder. We should continue to repurpose treatments and to recognise the role of serendipity. We should also investigate optimum combinations of pharmacological and psychotherapeutic treatments at different stages of the illness. Clarification of the mechanisms by which different treatments affect sleep and circadian rhythms and their relation with daily mood fluctuations is likely to help with the treatment selection for individual patients. To be economically viable, existing psychotherapy protocols need to be made briefer and more efficient for improved scalability and sustainability in widespread implementation. PMID:23663953

  15. Treatment for morbid obesity

    Carmichael, A

    1999-01-01

    There is no single unifying theory to explain the aetiology of obesity but several environmental factors, such as decreased physical activity and increased fat intake may contribute to its development in genetically predisposed individuals. Dietary and pharmacological treatments of morbid obesity have been proven to be unsuccessful. Modern surgical treatments have been shown to be effective in achieving significant weight loss with consequent reduction in morbidity. Despite the fact that surgical treatment of morbid obesity is the only therapeutic form that has stood the test of time, it still remains a crisis-driven form of therapy in the UK. It is probable that a better understanding of the aetiology and physiology of obesity may lead to the development of an effective pharmacological treatment of obesity in the future. However, until then, surgical treatment of morbid obesity should be considered as an effective and efficient way of treatment in selected cases.

    Water and wastewater utilities face major changes in their treatment systems as a result of recent environmental regulations. Not only do these new rules specify reduction requirements for contaminants not previously regulated, they also target the by-products of chlorination, which has been the basic disinfection technique in this country since the early days of municipal water treatment. As a result, EPRI has been working with the American Water Works Association Research Foundation and the Water Environment Research Foundation to support the development of advanced treatment alternatives and improve energy efficiency at treatment facilities. The work has identified a number of innovative, electrically based treatment technologies that provide the additional capabilities required, promote higher efficiency in treatment processes, and serve electric utilities' demand-side management objectives. 5 refs.

While in vasculitis of large vessels treatment with gluccocorticoids is often sufficient, in ANCA associated vasculitis almost always intial combination of gluccocorticoids and immunosupresive drugs (cyclofosfamide in severe forms; azatioprin and metotrrexate in moderate disease) is needed. Maintance therapy of ANCA associated vasculitis is methotrexate or azatioprin. From biologic therapy, in gigantocellular vasculitis treatment with tocilizumb has a great expectation, while in ANCA associated vasculitis recently rituximab was approved by regulatory agencies, and it is nontinferior to cyclofosfamide in induction of remission and prefarable in relapsing disease.

Patients must always be informed that it is long and difficult and that no significant response will be expected before 2 to 3 months of regular treatment. The authors present the different therapeutic agents and strategies. Isotretinoin should be used only in severe acne after failure of at least 3 months of a well conducted classical treatment and in nodulo-cystic acne; because of its major side effect of teratogenicity its use in adolescent girl's requires pregnancy testings before and during treatment and an effective contraception.

It is usually caused by a growth hormone secreting pituitary adenoma and is manifested by a variety of clinical features. Surgery is usually the treatment of choice, however over the last few years, several new methods of treatment have been developed. A recent consensus on the targets for treatment has led to multiple studies being conducted to assess the efficacy of the currently available options.

    Ankylosing spondylitis is a chronic, inflammatory, rheumatic disease that can reduce the quality of life and increase the risk of disability and mortality. It also causes direct and indirect economic losses due to health expenses and as a result of workforce loss. Management of this disease consists of pharmacological and nonpharmacological modalities. Until recently, pharmacological treatment options have been very limited. However, development of novel biological drugs revolutionized the management of this disease. The aim of this review article is to present an updated overview of the pharmacologic treatment of ankylosing spondylitis. Nonpharmacological treatment modalities including physiotherapy and exercise are only briefly mentioned and surgical treatment is not discussed.

    The number of adults undergoing orthodontic treatment has increased strongly and the average age that adult patients undergo orthodontic treatment increased steadily although 3/4 is still younger than 27 years. In adults the facial skeletal pattern can only be changed in a very confined way, consequently in case of an abnormal skeletal pattern one has to choose between a combined orthodontic-surgical approach (which is the case in 18% of the patients) and a compromised orthodontic treatment, if necessary combined with other disciplines. It is still controversial whether tooth movement in adults is slower and more difficult than in adolescents. The same holds true for the risk for loss of periodontal support, for root resorption, for gnathologic problems and for relapse. As related to these variables there appears to be a large individual variation. Many adults show one or more problems in their dentition that may influence their orthodontic treatment. About 60% of the adult patients need a multidisciplinary approach. The development of implantology and of bone regeneration and bone grafting has lead to more combined treatments. The risks of such complex treatment plans are generally larger than those for more simple kinds of treatment. A very careful treatment planning and good communication between the different specialists is essential. Moreover the treatment plan with all its (dis)advantages has to be extensively discussed with the patient.

    2005-05-01

    Primary headache disorders are often accompanied by neck pain or other symptoms referable to neck muscles. Therefore, physical therapy and other physical treatments are commonly prescribed for headache management. A medical literature review was completed in order to gather information regarding the efficacy of selected physical modalities in the treatment of primary and cervicogenic headache disorders. After analyzing the collected data, expert opinions were developed regarding the utility and efficacy of selected physical modalities in the management of primary and cervicogenic headaches. Based on this review, the following four expert opinions are presented: physical therapy is more effective than massage therapy or acupuncture for the treatment of tension-type headache and appears to be most beneficial for patients with a high frequency of headache attacks. Physical therapy is most effective for the treatment of migraine when combined with other treatments such as thermal biofeedback, relaxation training and exercise. Chiropractic manipulation demonstrated a trend towards benefit in the treatment of tension-type headache, but evidence is weak. Chiropractic manipulation is probably more effective in the treatment of tension-type headache than it is in the treatment of migraine. In general, strong evidence is lacking regarding the efficacy of these treatments in reducing headache frequency, intensity, duration and disability in many commonly encountered clinical situations. Many of the published case series and controlled studies are of low quality. Physical treatments are unlikely to pose a significant risk, with the exception of high velocity chiropractic manipulation of the neck. Consideration must be given to financial costs and lost treatment opportunity by prescribing potentially ineffective treatment. In the absence of clear evidence regarding their role in treatment, physicians and patients are advised to make cautious and individualized judgments about

    Eosinophilic esophagitis (EoE) is a relatively new entity with a significant amount of increased recognition over the last decade. The mainstay treatments of EoE are designed to eliminate the causative allergens or to reduce their effects on the esophageal mucosa. Common treatments include dietary modification, proton pump inhibitors, systemic and topical corticosteroids, and endoscopic treatments. As the pathogenesis of EoE is explored, new and novel treatments are being studied that target specific pathways and chemokines identified in as precipitating agents of EoE. This is a rapidly evolving field with significant ongoing research and clinical studies. Our review will therefore focus on current and novel treatment approaches to the disease.

    Remarkable therapeutic improvements have come forward recently for trigemino-autonomic cephalalgias. Attack treatment in cluster headache is based on sumatriptan and oxygen. Non-vasoconstrictive treatments are opening a new post-triptan era but are not yet applicable. Prophylactic treatment of cluster headache is based on verapamil and lithium. The efficacy of anti-epileptic drugs in cluster headache remains to be demonstrated. Surgical treatment aimed at the parasympathetic pathways and at the trigeminal nerve demonstrates a high rate of recurrence and adverse events and questions about the relevance of a "peripheral" target in cluster headache. The efficacy of continuous hypothalamic stimulation in patients with intractable headache constitutes a breakthrough, but must be demonstrated at a larger scale and the benefice/risk ratio must be carefully evaluated. Indomethacin still remains the gold standard in paroxysmal hemicrania treatment. Until recently SUNCT was considered an intractable condition. However there are some reports of complete relief with lamotrigine, topiramate and gabapentin.

For the last 25 years, APL has been treated with a combination of ATRA and chemotherapy for induction followed by consolidation and maintenance therapy. This general treatment approach has resulted in cure rates of 80–90%. ATO, originally approved in relapsed APL, has been incorporated into contemporary upfront treatment regimens with excellent response rates. Recent studies show that most patients with APL can be cured with ATRA and ATO alone, eliminating cytotoxic chemotherapy and resulting in superior outcomes compared to standard treatment.

    Pharmacological treatment is the mainstay for the treatment of epilepsy. However concerns regarding long-term side effects of drugs are increasingly voiced. Behavioral treatments including biofeedback, represents an alternative management option for the control of epilepsy. Biofeedback is a non-invasive bio-behavioral procedure through which patients can learn to gain psychophysiological control over seizures. This article will first overview seizure precipitation from a psychological perspective, and then introduce three major biofeedback treatments. Sensory motor rhythm (SMR) and slow cortical potential(SCP) biofeedback uses electroencephalographic parameters and are categorized as neurofeedback. Electrodermal activity (EDA) biofeedback focuses on modulation of peripheral sympathetic tone. The neural mechanisms underlying biofeedback treatment will be discussed in relation to thalamo-cortical regulation(of neural excitability across brain networks).

    2017-01-01

    Although the introduction of hepatitis B vaccine has been contributing to the reduction in the prevalence of hepatitis B virus (HBV) carriers worldwide, the treatment of children with chronic HBV infection is a challenge to be addressed. HBeAg seroconversion, which induces low replication of HBV, is widely accepted as the first goal of antiviral treatment in children with chronic hepatitis B. However, spontaneous HBeAg seroconversion is highly expected in children with chronic HBV infection. Therefore, the identification of children who need antiviral treatment to induce HBeAg seroconversion is essential in the management of chronic HBV infection. Guidelines and experts’ opinion show how to identify children who should be treated and how to treat them. If decompensated cirrhosis is absent, interferon-alpha is the first-line antiviral treatment. Nucleos(t)ide analogues (NAs), such as lamivudine, adefovir, entecavir and tenofovir, are also available for the treatment of children, although the approval age differs among them. If decompensated cirrhosis is present, NAs are the first-line antivirals. When the emergence of drug-resistant HBV variants is taken into consideration, entecavir (approved for age 2 years or older) and tenofovir (age 12 years or older), which have high genetic barriers, will play a central role in the treatment of HBV infection. However, the optimal duration of NA treatment and adverse events of long-term NA treatment remain unclear in children. In resource-constrained countries and regions, the financial burden of visiting hospitals, receiving routine blood examination and purchasing antiviral drugs is heavy. Moreover, there is no clear evidence that the induction of HBeAg seroconversion by antiviral treatment prevents the progression of liver disease to cirrhosis and hepatocellular carcinoma in children with chronic HBV infection. It is thus imperative to clarify the clinical impact of antiviral treatment in children with HBV infection. PMID

    2015-01-01

    The most common fractures of the spine are associated with the thoracolumbar junction. The goals of treatment of thoracolumbar fracture are leading to early mobilization and rehabilitation by restoring mechanical stability of fracture and inducing neurologic recovery, thereby enabling patients to return to the workplace. However, it is still debatable about the treatment methods. Neurologic injury should be identified by thorough physical examination for motor and sensory nerve system in order to determine the appropriate treatment. The mechanical stability of fracture also should be evaluated by plain radiographs and computed tomography. In some cases, magnetic resonance imaging is required to evaluate soft tissue injury involving neurologic structure or posterior ligament complex. Based on these physical examinations and imaging studies, fracture stability is evaluated and it is determined whether to use the conservative or operative treatment. The development of instruments have led to more interests on the operative treatment which saves mobile segments without fusion and on instrumentation through minimal invasive approach in recent years. It is still controversial for the use of these treatments because there have not been verified evidences yet. However, the morbidity of patients can be decreased and good clinical and radiologic outcomes can be achieved if the recent operative treatments are used carefully considering the fracture pattern and the injury severity.

    We define chronic migraine as that clinical situation in which migraine attacks appear 15 or more days per month. Until recently, and in spite of its negative impact, patients with chronic migraine were excluded of the clinical trials. This manuscript revises the current treatment of chronic migraine. The first step should include the avoidance of potential precipitating/aggravating factors for chronic migraine, mainly analgesic overuse and the treatment of comorbid disorders, such as anxiety and depression. The symptomatic treatment should be based on the use of nonsteroidal anti-inflammatory agents and triptans (in this case < 10 days per month). It is necessary to avoid the use of combined analgesics, opioids and ergotamine-containing medications. Preventive treatment includes a 'transitional' treatment with nonsteroidal anti-inflammatory agents or steroids, while preventive treatment exerts its actions. Even though those medications efficacious in episodic migraine prevention are used, the only drugs with demonstrated efficacy in the preventive treatment of chronic migraine are topiramate and pericranial infiltrations of Onabotulinumtoxin A.

Many of these decisions involve vegetation manipulations known as land treatments. Land treatments include activities such as removal or alteration of plant biomass, seeding burned areas, and herbicide applications. Data on these land treatments are usually stored at local offices, and gathering information across large spatial areas can be difficult. There is a need to centralize and store treatment data for Federal agencies involved in land treatments because these data are useful to land managers for policy and management and to scientists for developing sampling designs and studies. The Land Treatment Digital Library (LTDL) was created by the U.S. Geological Survey (USGS) to catalog information about land treatments on Federal lands in the western United States for all interested parties. The flexible framework of the library allows for the storage of a wide variety of data in different formats. The LTDL currently stores previously established land treatments or what often are called legacy data. The project was developed and has been refined based on feedback from partner agencies and stakeholders, with opportunity for the library holdings to expand as new information becomes available. The library contains data in text, tabular, spatial, and image formats. Specific examples include project plans and implementation reports, monitoring data, spatial data files from geographic information systems, digitized paper maps, and digital images of land treatments. The data are entered by USGS employees and are accessible through a searchable web site. The LTDL can be used to respond to information requests, conduct analyses and other forms of information syntheses, produce maps, and generate reports for DOI managers and scientists and other authorized users.

  11. Treatment decisions under ambiguity.

    PubMed

    Berger, Loïc; Bleichrodt, Han; Eeckhoudt, Louis

    2013-05-01

    Many health risks are ambiguous in the sense that reliable and credible information about these risks is unavailable. In health economics, ambiguity is usually handled through sensitivity analysis, which implicitly assumes that people are neutral towards ambiguity. However, empirical evidence suggests that people are averse to ambiguity and react strongly to it. This paper studies the effects of ambiguity aversion on two classical medical decision problems. If there is ambiguity regarding the diagnosis of a patient, ambiguity aversion increases the decision maker's propensity to opt for treatment. On the other hand, in the case of ambiguity regarding the effects of treatment, ambiguity aversion leads to a reduction in the propensity to choose treatment.

  12. [Treatment of acne].

    Acne is a disfiguring disease, occurring mainly in adolescence. It is a common disorder, affecting above 80% of adolescents in some degree. 50% wish to have treatment for the condition. Acne appears in many forms; from the more common comedonal and papulopustular types to the often devastating cystic and fulminant acne. Some patients develop disfiguring scarring and keloidal reactions, which persist for the rest of their lives. With the treatment facilities available in modern medicine, acne problems can be eliminated through topical and/or systemic treatment options.

    2012-01-01

    Childhood vitiligo differs from the adults by showing a higher incidence in females, segmental vitiligo being more common and less frequent association with other systemic autoimmune and endocrine disorders. Childhood vitiligo is often associated with a marked psychosocial and long lasting effect on the self-esteem of the affected children and their parents, hence an adequate treatment is very essential. Treatment of vitiligo is indeed a tough challenge for the dermatologists’ more so in the background of childhood vitiligo. Although multiple therapeutic modalities are available in the therapeutic armamentarium, not all can be used in children. This brief report updates regarding various therapies available in the treatment of childhood vitiligo. PMID:23248365

    2005-01-01

    Light-based treatments for acne are becoming increasingly commonplace in dermatology. This article reviews various light approaches in acne therapy. Methods are discussed from an anatomical and a functional perspective. The emphasis is on the practicality of treatment as well as the pros and cons of various devices. Also, a review of the recent literature is presented. The article is intended to give the reader a panoramic view of this still-young and developing area. Most likely, light-based acne treatment will receive more popularity as dermatologists learn how to integrate this type of therapy within the context of more established drug agents.

  15. Current treatments for scabies.

    PubMed

    Buffet, M; Dupin, N

    2003-04-01

    Scabies is a frequent interhuman ectoparasitic infection. Several treatments are available worldwide. There are local treatments: synthetic pyrethrins, benzyl benzoate, lindane, crotamiton. Recently a few studies were published concerning ivermectin, systemic antiparasitic agent use in onchocercosis treatment. We reviewed the literature with an evidence-based medicine method. We attempt to answer two questions in particular: what is the treatment of choice for common scabies in a patient otherwise in good health? What is the role of systemic ivermectin? We also report specific situations. Among local treatments, studies are heterogeneous according to products, countries, group of treated patients, with or without contact subjects, and the method of treatment application. There are very few high proof-level controlled studies. In France, a combination of benzyl benzoate 10% and sulfiram 2% is used most, according to professional consensus. The most studied product is the cream permethrin 5%, available in the USA and UK. Its efficacy seems slightly superior to lindane and less toxic. It is more efficient than crotamiton. There is no study comparing benzyl benzoate and permethrin. Concerning systemic ivermectin, five controlled studies showed its efficiency in common scabies. But its relative efficiency over local treatment has not been established. A few open studies showed its efficacy in institutional epidemic, profuse scabies and in HIV-positive patients. Local treatment of choice in common scabies remains to be determined among the four principal molecules. There is no study comparing permethrin or esdepallethrin to benzyl benzoate. In what cases should we prescribe crotamiton or lindane? Indication of ivermectin seems proved in common scabies and probably for HIV-positive patients. It remains to be determined if it should be prescribed in the first instance, be double or triple, be associated or not with local treatment. In case of keratotic scabies, ivermectin

    2015-05-01

    Until quite recently, clinical guidelines and reviews on the treatment of hyperhidrosis advised against the use of systemic therapies based on their unacceptable adverse effects and a lack of evidence of usefulness. Numerous studies published over the past few years, however, have shown that, when used appropriately, these treatments are effective and in general have a favorable tolerability profile, making them an additional option for the treatment of hyperhidrosis, particularly for disease that is widespread, multifocal, or resistant to other treatments. In this review, the first of its kind, we examine the systemic therapies available for hyperhidrosis, including antihypertensives, psychoactive agents, and in particular oral anticholinergics, although none of these drugs are currently approved for this indication.

    2000-01-01

    A thermal treatment wall emplaced to perform in-situ destruction of contaminants in groundwater. Thermal destruction of specific contaminants occurs by hydrous pyrolysis/oxidation at temperatures achievable by existing thermal remediation techniques (electrical heating or steam injection) in the presence of oxygen or soil mineral oxidants, such as MnO.sub.2. The thermal treatment wall can be installed in a variety of configurations depending on the specific objectives, and can be used for groundwater cleanup, wherein in-situ destruction of contaminants is carried out rather than extracting contaminated fluids to the surface, where they are to be cleaned. In addition, the thermal treatment wall can be used for both plume interdiction and near-wellhead in-situ groundwater treatment. Thus, this technique can be utilized for a variety of groundwater contamination problems.

    Chang, Aileen Y.; Werth, Victoria P.

    2011-01-01

    Cutaneous lupus erythematosus (CLE) is an autoimmune, inflammatory skin disease seen in patients with or without systemic lupus erythematosus (SLE). The management of CLE includes treatment and prevention of lesions, as well as routine assessment for systemic disease. Treatment options include both topical and systemic therapies. Topical therapies include corticosteroids and calcineurin inhibitors. Systemic therapies generally fall under one of three categories: antimalarials, immunomodulators, such as dapsone and thalidomide, and immunosuppressives, such as methotrexate and mycophenolate. Evidence for the treatment of CLE is limited by few prospective studies, as well as lack of a validated outcome measure up until recently. There is good evidence to support the use of topical steroids and calcineurin inhibitors, though most of these trials have not used placebo or vehicle controls. There have been no randomized placebo-controlled trials evaluating systemic therapies for the treatment of CLE. PMID:21503694

    The results of an experimental research program to investigate the potential of improving compressor stall margin by the application of hub treatment are presented. Extensive tuft probing showed that the two-stage, 0.5 radius ratio compressor selected for the test was indeed hub critical. Circumferential groove and baffled wide blade angle slot hub treatments under the stators were tested. Performance measurements were made with total and static pressure probes, wall static pressure taps, flow angle measuring instrumentation and hot film anemometers. Stator hub treatment was not found to be effective in improving compressor stall margin by delaying the point of onset of rotating stall or in modifying compressor performance for any of the configurations tested. Extensive regions of separated flow were observed on the suction surface of the stators near the hub. However, the treatment did not delay the point where flow separation in the stator hub region becomes apparent.

    2013-01-01

    Ganglion cysts are soft tissue swellings occurring most commonly in the hand or wrist. Apart from swelling, most cysts are asymptomatic. Other symptoms include pain, weakness, or paraesthesia. The two main concerns patients have are the cosmetic appearance of the cysts and the fear of future malignant growth. It has been shown that 58% of cysts will resolve spontaneously over time. Treatment can be either conservative or through surgical excision. This review concluded that nonsurgical treatment is largely ineffective in treating ganglion cysts. However, it advised to patients who do not surgical treatment but would like symptomatic relief. Compared to surgery, which has a lower recurrence rate but have a higher complication rate with longer recovery period. It has been shown that surgical interventions do not provide better symptomatic relief compared to conservative treatment. If symptomatic relief is the patient's primary concern, a conservative approach is preferred, whilst surgical intervention will decrease the likelihood of recurrence.

    Somnambulism is an arousal disorder that is usually benign, self-limited and only infrequently requires treatment. Chronic sleepwalking in children has been shown to be associated with behavioral problems and poor emotional regulation. Most cases can be diagnosed with careful noting of case history and epilepsy is an important differential diagnosis. Management with pharmacological and behavioural measures is usually safe and effective. We present two cases of somnambulism that highlight the importance of the diagnosis and treatment of this condition.

    1997-03-01

    In developing their Site Treatment Plans (STPs), many of the Department of Energy installations identified some form of portable treatment, to facilitate compliant disposition of select mixed low-level wastestreams. The Environmental Management Office of Science and Technology requested that a systems study be performed to better define the potential role of portable treatment with respect to mixed low-level waste, highlight obstacles to implementation, and identify opportunities for future research and development emphasis. The study was performed by first establishing a representative set of mixed waste, then formulating portable treatment system concepts to meet the required processing needs for these wastes. The portable systems that were conceptualized were evaluated and compared to a fixed centralized treatment alternative. The system evaluations include a life-cycle cost analysis and an assessment of regulatory, institutional, and technical issues associated with the potential use of portable systems. The results of this study show that when all costs are included, there are no significant cost differences between portable systems and fixed systems. However, it is also emphasized that many uncertainties exist that could impact the cost of implementing portable treatment systems. Portable treatment could be made more attractive through private sector implementation, although there is little economic incentive for a commercial vendor to develop small, specialized treatment capabilities with limited applicability. Alternatively, there may also be valid reasons why fixed units cannot be used for some problematic wastestreams. In any event, there are some site-specific problems that still need to be addressed, and there may be some opportunity for research and development to make a positive impact in these areas.

  19. Laser treatment in gynecology

    NASA Astrophysics Data System (ADS)

    de Riese, Cornelia

    2004-07-01

    This presentation is designed as a brief overview of laser use in gynecology, for non-medical researchers involved in development of new laser techniques. The literature of the past decade is reviewed. Differences in penetration, absorption, and suitable delivery media for the beams dictate clinical application. The use of CO2 laser in the treatment of uterine cervical intraepithelial lesions is well established and indications as well as techniques have not changed over 30 years. The Cochrane Systematic Review from 2000 suggests no obviously superior technique. CO2 laser ablation of the vagina is also established as a safe treatment modality for VAIN. CO2 laser permits treatment of lesions with excellent cosmetic and functional results. The treatment of heavy menstrual bleeding by destruction of the endometrial lining using various techniques has been the subject of a 2002 Cochran Database Review. Among the compared treatment modalities are newer and modified laser techniques. Conclusion by reviewers is that outcomes and complication profiles of newer techniques compare favorably with the gold standard of endometrial resection. The ELITT diode laser system is one of the new successful additions. CO2 laser is also the dominant laser type used with laparoscopy for ablation of endometriotic implants. Myoma coagulation or myolysis with Nd:Yag laser through the laparoscope or hysteroscope is a conservative treatment option. Even MRI guided percutaneous approaches have been described. No long-term data are available.

    2012-01-01

    Surface plays a crucial role in biological interactions. Surface treatments have been applied to metallic biomaterials in order to improve their wear properties, corrosion resistance, and biocompatibility. A systematic review was performed on studies investigating the effects of implant surface treatments on biocompatibility. We searched the literature using PubMed, electronic databases from 1990 to 2009. Key words such as implant surface topography, surface roughness, surface treatment, surface characteristics, and surface coatings were used. The search was restricted to English language articles published from 1990 to December 2009. Additionally, a manual search in the major dental implant journals was performed. When considering studies, clinical studies were preferred followed by histological human studies, animal studies, and in vitro studies. A total of 115 articles were selected after elimination: clinical studies, 24; human histomorphometric studies, 11; animal histomorphometric studies, 46; in vitro studies, 34. The following observations were made in this review: · The focus has shifted from surface roughness to surface chemistry and a combination of chemical manipulations on the porous structure. More investigations are done regarding surface coatings. · Bone response to almost all the surface treatments was favorable. · Future trend is focused on the development of osteogenic implant surfaces. Limitation of this study is that we tried to give a broader overview related to implant surface treatments. It does not give any conclusion regarding the best biocompatible implant surface treatment investigated till date. Unfortunately, the eventually selected studies were too heterogeneous for inference of data.

  1. Prophylactic Treatment of Migraine

    PubMed Central

    GÜRSOY, Azize Esra; ERTAŞ, Mustafa

    2013-01-01

    Migraine is a common chronic neurological disease characterized by episodic attacks of headache and associated symptoms. The pharmacological treatment of migraine may be acute or prophylactic, and patients with frequent, severe headaches often require both approaches. Prophylactic treatment is used to reduce the frequency, duration, or severity of attacks, to enhance the benefits of acute treatments, and to improve patient’s ability to function normally. Prophylactic treatment may also prevent progression from episodic migraine to chronic migraine and may result in reductions in health-care cost. The currently available pharmacological options for migraine prophylaxis include a wide array of medications. The major medication groups for prophylactic treatment include β-blockers, anticonvulsant, drugs such as topiramate and valproate, antidepressant drugs, such as amitriptyline and selective serotonin and selective serotonin-norepinephrine reuptake inhibitors (SNRIs), calcium channel antagonists and neurotoxins. The agent for prophylactic treatment should be chosen based on the efficacy and side-effect profile of the drug, and the patient’s coexistent and comorbid conditions.

  2. Drug treatment of hyperprolactinemia.

    PubMed

    Chanson, P; Borson-Chazot, F; Chabre, O; Estour, B

    2007-06-01

    Medical treatment of hyperprolactinemia is based upon use of dopamine agonists (DA): bromocriptine, lisuride, quinagolide and cabergoline. In over 80% of cases, these drugs induce normal prolactinemia and ovulatory cycles. In resistant cases, the DA should be changed. Tolerance may occasionally be poor, particularly with bromocriptine, which appears less well-tolerated than quinagolide and than cabergoline above all. In the event of intolerance to a given DA, another should be tried. In patients with macroprolactinoma treated with DA, MRI monitoring should be carried out after 3 months of treatment to verify tumor size reduction, then after 1 year, yearly for the next 5 years and once every 5 years if adenoma size is stable. In cases of microprolactinoma, control under treatment is pointless. MRI may be performed after 1 year and then after 5 years. Once normal prolactin levels have been achieved, attempts may be made to stop the treatment. When a prolonged treatment is interrupted, especially with cabergoline, progressive increase in serum prolactin and return of hyperprolactinemia symptoms are seen in only around 20-30% of cases, particularly when residual adenoma exists after prolonged treatment. Nevertheless, prolactin levels should continue to be monitored after discontinuation of DA, possibly with MRI monitoring, since prolactin levels may rise again after a number of months or years. When normal prolactin levels have been achieved with DA, another solution consists in reducing the dose or dosing frequency of DA in steps to the lowest effective dose consistent with maintenance of normal prolactin levels and stable adenoma size. For drug-induced hyperprolactinemia, where the causative medication cannot be withdrawn, it is often pointless and possibly even dangerous to administer a DA. It is therefore necessary to check for absence of pituitary adenoma and where necessary, begin treatment with sex steroids so as to ensure satisfactory impregnation with sex

  3. Pharmacoeconomics of antibacterial treatment.

    PubMed

    Davey, P G; Malek, M M; Parker, S E

    1992-06-01

    Antibacterial drugs account for between 3 and 25% of all prescriptions, between 6 and 21% of the total market value of drugs in a single country, and up to 50% of the drug budget in hospitals. Bacterial infection is widely perceived as disease caused by harmful outside agents which can be isolated and tested to select the best drug for treatment. In fact, the need for any treatment and the pros and cons of different drugs are just as debatable as in any other therapeutic area. Moreover, the bacteria which make up the normal flora of the body fulfil important roles, so that the ecological implications of treatment for the individual and for society should be considered in assessing the costs and consequences of antibacterial treatment. In this review we outline the most important issues relating to the treatment of bacterial infection in the community and in the hospital, contrasting information from developed and developing countries where appropriate. We review the existing literature on economic evaluation, but in general most of the literature deals with containing the costs of antibacterial drugs in hospitals, and there are many gaps in the literature on cost-effectiveness of treatment. Consequently there are still extreme variations in medical practice which present a challenge for future evaluation. As the outcomes of antibacterial treatment are apparent in a few weeks or months, this is an ideal field for testing pharmacoeconomic methodology. The desire to overcome medical practice variation through consensus statements should be avoided. Instead we recommend wider application of decision analysis to acknowledge that choices exist for the diagnosis and treatment of bacterial infection and to gather information about the implications of these choices. Much of the existing literature would be improved by a more explicit definition of costs. Direct costs to the health services should be distinguished from non medical costs. Moreover, the analysis should

  4. Treatment preparatory to psychoanalysis.

    PubMed

    Bernstein, S B

    1983-01-01

    Many potentially analyzable adult patients with unimpaired egos require a period of preparatory treatment before entering psychoanalysis. There has been some concern that such face-to-face treatment, if done with the same analyst, would influence the subsequent analysis by stimulating inaccessible unconscious fantasies, gratifying infantile wishes, or making the analyst too "real." This would necessitate a change to another analyst after the preparatory treatment, in order that the analysis be unmodified and have the most profound and definitive effects. Increasingly, however, many analysts practicing in the classical tradition have found preparatory treatment compatible with progression to psychoanalysis with the same analyst. But neither this process nor the concerns about it have been described to any extent in the literature. This may be, in part, because of historical conceptions that the effects of psychotherapy rest mainly on suggestion, lack of a full theoretical framework for psychotherapy compared with psychoanalysis, and disagreement as to whether these procedures are dichotomous or on a continuum. In order to discuss most clearly the basic issues involved in preparatory treatment that progresses to analysis with the same analyst, a case is presented in which complex variables were at a minimum; the transition could be anticipated, so that interventions, which might complicate the analysis, could be avoided; and the preparatory treatment was necessary to attenuate specific resistances to the meaning of analysis. The patient described here resisted analysis as it represented the facilitator of a feared regression and the reactivator of warded-off libidinal and aggressive impulses and wishes which the patient experienced as more controllable in psychotherapy. The meanings and effects of the prior treatment and the transition on the analytic transference neurosis, resistances, countertransferences, as well as possible effects on analytic technique, are

  5. Treatment of Radiation Injury

    Significance: Radiation exposure as a result of radiation treatment, accident, or terrorism may cause serious problems such as deficiency due to necrosis or loss of function, fibrosis, or intractable ulcers in the tissues and organs. When the skin, bone, oral mucous membrane, guts, or salivary glands are damaged by ionizing radiation, the management and treatment are very lengthy and difficult. Critical Issues: In severe and irreversible injuries, surgery remains the mainstay of treatment. Several surgical procedures, such as debridement, skin grafting, and local and free-vascularized flaps, are widely used. Recent Advances: In specific cases of major morbidity or in high-risk patients, a newly developed therapy using a patient's own stem cells is safe and effective. Adipose tissue, normally a rich source of mesenchymal stem cells, which are similar to those from the bone marrow, can be harvested, since the procedure is easy, and abundant tissue can be obtained with minimal invasiveness. Future Directions: Based on the molecular basis of radiation injuries, several prospective treatments are under development. Single-nucleotide polymorphisms focus on an individual's sensitivity to radiation in radiogenomics, and the pathology of radiation fibrosis or the effect of radiation on wound healing is being studied and will lead to new insight into the treatment of radiation injuries. Protectors and mitigators are being actively investigated in terms of the timing of administration or dose. PMID:24761339

  6. Adjuvant Treatment of Melanoma

    Melanomas represent 4% of all malignant tumors of the skin, yet account for 80% of deaths from skin cancer.While in the early stages patients can be successfully treated with surgical resection, metastatic melanoma prognosis is dismal. Several oncogenes have been identified in melanoma as BRAF, NRAS, c-Kit, and GNA11 GNAQ, each capable of activating MAPK pathway that increases cell proliferation and promotes angiogenesis, although NRAS and c-Kit also activate PI3 kinase pathway, including being more commonly BRAF activated oncogene. The treatment of choice for localised primary cutaneous melanoma is surgery plus lymphadenectomy if regional lymph nodes are involved. The justification for treatment in addition to surgery is based on the poor prognosis for high risk melanomas with a relapse index of 50–80%. Patients included in the high risk group should be assessed for adjuvant treatment with high doses of Interferon-α2b, as it is the only treatment shown to significantly improve disease free and possibly global survival. In the future we will have to analyze all these therapeutic possibilities on specific targets, probably associated with chemotherapy and/or interferon in the adjuvant treatment, if we want to change the natural history of melanomas.

  7. Treatments for hidradenitis suppurativa.

    PubMed

    Andersen, R Kjærsgaard; Jemec, Gregor B E

    Hidradenitis suppurativa (HS) is not easily treated. Although not uncommon, HS is often misdiagnosed outside specialized clinics and inappropriately treated as a simple boil or abscess. In recent years, guidelines have been developed on the basis of expert opinion and the available literature. A multifaceted approach is necessary as HS lesions include both inflammation (amenable to medical treatment) as well as fibrosis (amenable to surgery only). The recommended antiinflammatory therapies encompass both antimicrobials and regular anti-inflammatory drugs. We have, therefore, reviewed treatments with the following agents: clindamycin, tetracycline, rifampicin, ertapenem, dapsone, triamcinolone, infliximab, adalimumab, and anakinra. The development of new medical treatments, however, is an ongoing effort, and important new data have been presented since the publication of the guideline. The current approach to the management of fibrotic lesions is surgery. It is important, as manifest fibrosis is generally not susceptible to medical treatment. Here minor excision, carbon dioxide-laser, and major surgery are discussed, and current evidence supporting their use is provided. A comprehensive three-pronged approach with adjuvant therapy, medical therapy, and surgery is recommended. The importance of adjuvant therapy, that is, pain management, wound care, and attention, is stressed. Adjuvant therapy not only plays a major role in patients' perception of a successful treatment but also is of practical importance to their coping and self-management. HS presents a significant unmet need, and this review provides a mechanistic update on the current real-world therapeutic option for the management of this distressing disease.

    2010-01-01

    Articles that update the state of knowledge regarding osteoporosis run the risk of quickly becoming obsolete because research and studies on osteoporosis today are arousing great interest among researchers, the pharmaceutical and medical equipment industries, governments and even WHO. All orthopedists know about osteoporosis because of its most deleterious effect: osteoporotic fracture. Osteoporosis without fractures does not arouse suspicion because this is a pathological condition with a nonspecific clinical profile. Osteoporotic fractures have an economic cost (from treatment), a social cost (from its sequelae) and a medical cost (from deaths). Many fractures could be avoided through diagnosing osteoporosis prior to the first fracture and thus many temporary and permanent disabilities could be avoided and many lives saved. Awareness of the risk factors for osteoporosis raises suspicions and bone densitometry aids in diagnosis. Treatment should be based on the physiopathology of the disease. Hence, for prevention or treatment of osteoporosis, the activity of osteoclasts should be diminished or the activity of osteoblasts should be increased, or both. Treatment that reduces the incidence of fractures by improving the bone geometry and microarchitecture would be ideal. Newly formed bone tissue needs to have good cell and matrix quality, normal mineralization, a good ratio between mineralized (mechanically resistant) and non-mineralized (flexible) bone, and no accumulated damage. The ideal treatment should have a positive remodeling rate and fast and long-lasting therapeutic effects. Such effects need to be easily detectable. They need to be safe.

    The U.S. Department of Energy (DOE) is responsible for the final disposition of legacy spent nuclear fuel (SNF). As a response, DOE's National Spent Nuclear Fuel Program (NSNFP) has been given the responsibility for the disposition of DOE-owned SNF. Many treatment technologies have been identified to treat some forms of SNF so that the resulting treated product is acceptable by the disposition site. One of these promising treatment processes is the electrometallurgical treatment (EMT) currently in development; a second is an Acid Wash Decladding process. The NSNFP has been tasked with identifying possible strategies for the deployment of these treatment processes in the event that a treatment path is deemed necessary. To support the siting studies of these strategies, economic evaluations are being performed to identify the least-cost deployment path. This model (tool) was developed to consider the full scope of costs, technical feasibility, process material disposition, and schedule attributes over the life of each deployment alternative. Using standard personal computer (PC) software, the model was developed as a comprehensive technology economic assessment tool using a Life-Cycle Cost (LCC) analysis methodology. Model development was planned as a systematic, iterative process of identifying and bounding the required activities to dispose of SNF. To support the evaluation process, activities are decomposed into lower level, easier to estimate activities. Sensitivity studies can then be performed on these activities, defining cost issues and testing results against the originally stated problem.

    Abstract The past few decades have seen a number of medical breakthroughs that enabled the effective treatment of a range of conditions, transforming them from fatal into manageable ones. Examples include certain cancers and HIV. Conversely, progress on dementia has been limited. There are currently no treatments that will cure or even alter the progressive course of dementia, despite ongoing research investigating new therapies and care options. The UK Department of Health is interested in the potential to learn from other disease areas to better understand the particular social, economic, political, legislative and scientific contexts that have contributed to accelerating progress and breakthroughs in treatment. Such learning could helpfully inform dementia research and innovation efforts, and help identify levers for supportive policy development. This project analysed breakthroughs in the treatment of four selected conditions of ill health and seeks to identify potentially transferable lessons for the dementia context. Using evidence review and key informant interviews we sought to identify the series of “events” that eventually led to a given breakthrough, and the key milestones in the process that have helped improve understanding and potential for treatment. We also aimed to capture the temporal and causal relationships between “notable” events looking at a variety of factors implicated in the breakthrough pathway. The focus of this work was on political, economic, social, scientific and technological, and legal, regulatory and environmental factors. PMID:28083433

  12. Treatment options for insomnia.

    Ramakrishnan, Kalyanakrishnan; Scheid, Dewey C

    2007-08-15

    The frequency of sleep disruption and the degree to which insomnia significantly affects daytime function determine the need for evaluation and treatment. Physicians may initiate treatment of insomnia at an initial visit; for patients with a clear acute stressor such as grief, no further evaluation may be indicated. However, if insomnia is severe or long-lasting, a thorough evaluation to uncover coexisting medical, neurologic, or psychiatric illness is warranted. Treatment should begin with nonpharmacologic therapy, addressing sleep hygiene issues and exercise. There is good evidence supporting the effectiveness of cognitive behavior therapy. Exercise improves sleep as effectively as benzodiazepines in some studies and, given its other health benefits, is recommended for patients with insomnia. Hypnotics generally should be prescribed for short periods only, with the frequency and duration of use customized to each patient's circumstances. Routine use of over-the-counter drugs containing antihistamines should be discouraged. Alcohol has the potential for abuse and should not be used as a sleep aid. Opiates are valuable in pain-associated insomnia. Benzodiazepines are most useful for short-term treatment; however, long-term use may lead to adverse effects and withdrawal phenomena. The better safety profile of the newer-generation nonbenzodiazepines (i.e., zolpidem, zaleplon, eszopidone, and ramelteon) makes them better first-line choices for long-term treatment of chronic insomnia.

  13. Hirsutism: diagnosis and treatment.

    Hohl, Alexandre; Ronsoni, Marcelo Fernando; Oliveira, Mônica de

    2014-03-01

    Hirsutism is defined as excessive terminal hair growth in androgen-dependent areas of the body in women, which grows in a typical male distribution pattern. Hirsutism is a common clinical problem in women, and the treatment depends on the cause. The condition is often associated with a loss of self-esteem. Hirsutism reflects the interaction between circulating androgen concentrations, local androgen concentrations, and the sensitivity of the hair follicle to androgens. Polycystic ovary syndrome and idiopathic hirsutism are the most common causes of the condition. A woman's history and, physical examination are particularly important in evaluating excess hair growth. The vast majority of women with hirsutism have the idiopathic variety, and the diagnosis is made by exclusion. Serum testosterone level>200 ng/dL is highly suggestive of adrenal or ovarian tumor. Treatment of hirsutism should be based on the degree of excess hair growth presented by the patient and in the pathophysiology of the disorder. Treatment includes lifestyle therapies, androgen suppression, peripheral androgen blockage, and cosmetic treatments. The current review discusses definition, pathogenesis, physiopathology, differential diagnosis, diagnostic strategies, and treatment.

    2012-07-01

    The history of the development of generic phytosanitary irradiation (PI) treatments is discussed beginning with its initial proposal in 1986. Generic PI treatments in use today are 150 Gy for all hosts of Tephritidae, 250 Gy for all arthropods on mango and papaya shipped from Australia to New Zealand, 300 Gy for all arthropods on mango shipped from Australia to Malaysia, 350 Gy for all arthropods on lychee shipped from Australia to New Zealand and 400 Gy for all hosts of insects other than pupae and adult Lepidoptera shipped to the United States. Efforts to develop additional generic PI treatments and reduce the dose for the 400 Gy treatment are ongoing with a broad based 5-year, 12-nation cooperative research project coordinated by the joint Food and Agricultural Organization/International Atomic Energy Agency Program on Nuclear Techniques in Food and Agriculture. Key groups identified for further development of generic PI treatments are Lepidoptera (eggs and larvae), mealybugs and scale insects. A dose of 250 Gy may suffice for these three groups plus others, such as thrips, weevils and whiteflies.

    A positive mycological examination is required before discussion of treatment of onychomycosis. Onychomycosis is most commonly due to dermatophytes in association with tinea pedis and/or tinea manuum. It is a catched infection. Candida onychomycosis is a rare opportunistic infection and onychomycosis due to non-dermatophytic moulds is very rare as a "chance mishap". The treatment of dermatophyte onychomycosis takes each infected part of the nail into account. Topical antifungal agents should be reserved for mild to moderate onychomycosis. Systemic antifungal agents are required to severe onychomycosis. In all cases, removal of infected nail parts is useful to facilitate the penetration of antifungal drugs and eradication of reinfection sites may be done to prevent recurrences and relapses. In primary, Candida onychomycosis treatment with topical antifungal drugs may be effective but in case of treatment failure, a systemic therapy is required. Suppression predisposing factors is useful. The treatment of non-dermatophytic moulds onychomycosis is still a challenge. Except Neoscytalidium spp., which mimic a dermatophytosis, non-dermatophytic moulds may be isolated from dystrophic nails and it is always difficult to specify their role as a primary pathogen or as a colonizer of nails. The available topical and systemic antifungal drugs are not effective against these non-dermatophytic moulds except itraconazole for onychomycosis due to Aspergillus spp. New therapy such as light and laser therapy are in evaluation.

    The NIMH Treatment Strategies in Schizophrenia (TSS) collaborative study group investigated the efficacy of antisychotic drug maintenance strategies involving reduced medication exposure in interaction with applied and supportive family management for the long-term treatment of schizophrenia. Therapy was provided at five centers by 25 clinicians who did not participate in the development of the therapies. They were trained by two of the authors, I.R.H.F and C.W.M, in applied family management, a homebased treatment derived from the behavioral family therapy developed by them. Clinicians’ characteristics, selection, and training methods, as well as patient rehospitalization rates, are reported for the two family management conditions. The TSS study represents a bridge between the development of a novel therapy and its dissemination in general clinical practice. PMID:22700264

Identification is secured through instrumental variables and/or conditional independence (matching) assumptions. We decompose treatment effects into direct effects and continuation values associated with moving to the next stage of a decision problem. Using our framework, we decompose the IV estimator, showing that IV generally does not estimate economically interpretable or policy relevant parameters in prototypical dynamic discrete choice models, unless policy variables are instruments. Continuation values are an empirically important component of estimated total treatment effects of education. We use our analysis to estimate the components of what LATE estimates in a dynamic discrete choice model. PMID:27041793

    In this article the most frequent and interesting treatments for parasomnias are reviewed. Arousal disorders, REM sleep behavior disorders and nightmares, bruxism (which can occur in any sleep state) are considered. The pathophysiological mechanisms of parasomnias are unknown, explaining why there is rarely a specific treatment precipitating. Management depends on the patient's age, the frequency and intensity of the episodes, the familial structure, the presence of precipitating and risk factors, psychological disorders and the parasomnia itself. Different therapeutic approaches are described including (1), explanation and reassurance, (2) counselling to avoid precipitating factors such as irregular sleep patterns, alcohol or drug intake (3) strategies to avoid injury (4) psychological approaches such as behavioral therapies in some parasomnias such as nightmares or arousal disorders. However, very few controlled studies have been done making it difficult to provide recommendations based on controlled clinical trials. Pharmacologic treatments are rarely necessary except in REM sleep behavior disorders; they are most often needed for short term.

    Synopsis The dystonias are a group of disorders characterized by excessive involuntary muscle contractions leading to abnormal postures and/or repetitive movements. There are many different clinical manifestations and many different causes. A careful assessment of the clinical manifestations is helpful for identifying syndromic patterns that focus diagnostic testing on potential causes. If a cause can be identified, specific etiology-based treatments may be available. However, in the majority of cases, a specific cause cannot be identified, and treatments are based on symptoms. Treatment options include counseling and education, oral medications, botulinum toxin injections, and several surgical procedures. A substantial reduction in symptoms and improved quality of life can be achieved in the majority of patients by combining these various options. PMID:25432724

    Gout is a commonly occurring medical condition that can lead to significant morbidity. Therapies available for the treatment of both acute and chronic gouty arthritis have not changed significantly since the 1960s. Although these treatments are well established, they are often contraindicated in the presence of various different comorbidities, including diabetes, renal insufficiency, hypertension and gastrointestinal disease, all of which can occur frequently in patients with gout. Therefore, new treatments are needed. This review describes recent advances in therapeutics for gout, including drugs designed to reduce levels of urate and to inhibit acute or chronic inflammation. While some of these strategies are currently available, others are undergoing regulatory evaluation or are at earlier stages of development.

    The medical role in the treatment of delinquency is a limited one. There is conflicting evidence as to whether treatment aims should be directed towards the individual, to the family, the institution, or the therapist. Nevertheless there seems to be a consensus of opinion that short term, focused therapies aimed at improving educational, vocational and social skills, possibly from a preschool age, are the most effective. Any treatment gains achieved while in residential care appear to be short lived. It therefore seems that this should be reserved for those individuals who commit repeated, violent crimes and for those from very damaging family backgrounds who repeatedly abscond or absent themselves from community based programmes.

    PubMed

    Kravets, Igor

    2016-03-01

    Hyperthyroidism is an excessive concentration of thyroid hormones in tissues caused by increased synthesis of thyroid hormones, excessive release of preformed thyroid hormones, or an endogenous or exogenous extrathyroidal source. The most common causes of an excessive production of thyroid hormones are Graves disease, toxic multinodular goiter, and toxic adenoma. The most common cause of an excessive passive release of thyroid hormones is painless (silent) thyroiditis, although its clinical presentation is the same as with other causes. Hyperthyroidism caused by overproduction of thyroid hormones can be treated with antithyroid medications (methimazole and propylthiouracil), radioactive iodine ablation of the thyroid gland, or surgical thyroidectomy. Radioactive iodine ablation is the most widely used treatment in the United States. The choice of treatment depends on the underlying diagnosis, the presence of contraindications to a particular treatment modality, the severity of hyperthyroidism, and the patient's preference.

    Borrelia burgdorferi sensu lato is the causative agent of Lyme borreliosis in humans. This inflammatory disease can affect the skin, the peripheral and central nervous system, the musculoskeletal and cardiovascular system and rarely the eyes. Early stages are directly associated with viable bacteria at the site of inflammation. The pathogen-host interaction is complex and has been elucidated only in part. B. burgdorferi is highly susceptible to antibiotic treatment and the majority of patients profit from this treatment. Some patients develop chronic persistent disease despite repeated antibiotics. Whether this is a sequel of pathogen persistence or a status of chronic auto-inflammation, auto-immunity or a form of fibromyalgia is highly debated. Since vaccination is not available, prevention of a tick bite or chemoprophylaxis is important. If the infection is manifest, then treatment strategies should target not only the pathogen by using antibiotics but also the chronic inflammation by using anti-inflammatory drugs. PMID:20067594

    Creativity can be defined as the ability to understand, develop, and express, in a systematic fashion, novel orderly relationships. It is sometimes difficult to separate cognitive skills requisite for the creative process from the drive that generates unique new ideas and associations. Epilepsy itself may affect the creative process. The treatment of epilepsy and its comorbidities, by altering or disrupting the same neural networks through antiseizure drugs (ASDs), treatment of epilepsy comorbidities, ablative surgery, or neurostimulation may also affect creativity. In this review, we discuss the potential mechanisms by which treatment can influence the creative process and review the literature on the consequences of therapy on different aspects of creativity in people with epilepsy.

  12. Enhanced industrial wastewater treatment

    1997-12-31

    The sodium sulfide/ferrous sulfate (SS/FS) process is a treatment technology for the reduction of hexavalent chromium and precipitation of heavy metals in industrial wastewater treatment plants (IWTP). When the ferrous ion, as ferrous sulfate, is mixed with sulfide, the hexavalent chromium is rapidly reduced to its trivalent state at a neutral pH and then precipitated. SS/FS technology can be used to replace the current hydroxide treatment chemistry in Navy IWTPs. This paper will present the results and lessons learned from full-scale implementation of SS/FS at Naval Undersea Warfare Center (NUWC) Keyport, Washington. The SS/FS treatment process reduced the chemical cost by fifty nine percent and sludge disposal cost by thirty one percent. On an annual basis total cost savings amounted to $31,950 or thirty four percent. The SS/FS treatment process lowered the amount of treatment chemicals used in the IWTP. Furthermore, metal sulfides tend to be two to three orders of magnitude less soluble than their corresponding metal hydroxides. This allows for cleaner effluent, which will help the facility meet environmental discharge requirements. Further benefits include the removal from the shop area of the high pressure sulfur dioxide cylinder (used in the hydroxide process), a faster and more reliable chrome reduction method, neutral pH operation that extends tank and equipment life, and less acid and caustic chemicals stored on the shop floor. As Navy activities respond to the ever increasing pressures to do more with less, the SS/FS process can help them meet the increasingly stringent standards.

Achilles tendinosis refers to a degenerative process of the tendon without histologic or clinical signs of intratendinous inflammation. Treatment is based on whether to stimulate or prevent neovascularization. Thus, until now, there is no consensus as to the best treatment for this condition. This paper aims to review the common ways of treating this condition from the conservative to the surgical options.

    Enuresis is a common pediatric problem that creates a lot of stress for both the child and his/her family. Unfortunately, many of these patients do not seek medical attention for evaluation and treatment. It is important in the care of the child with enuresis to understand the definitions of the disorder, routinely ask about bowel and bladder habits, clarify the nature of the wetting (daytime, nighttime, or both) in the child, and perform a thorough history and physical examination. Laboratory studies are often minimal. Treatment (behavioral or medicinal) is dependent on the type of enuresis present, and patient compliance. Successful management of enuresis has benefits to both the child and family.

  16. Treatment of Kounis syndrome.

    2010-09-03

    Kounis syndrome is potentially a life-threatening medical emergency with both a severe allergic reaction and acute coronary syndrome. Most of the information about this syndrome has come from the case reports. The management of these patients may be challenging for clinicians, and unfortunately guidelines have not been established yet. In this article, we review the current guidelines of acute coronary syndromes and anaphylaxis along with the published cases with Kounis syndrome secondary to beta-lactam antibiotics. We have summarized our recommendations for the work-up and treatment of Kounis syndrome from available data. Obviously, larger prospective studies are needed to establish definitive treatment guidelines for these patients.

    Ayuk, John; Gittoes, Neil J L

    2014-04-01

    Serum magnesium concentration is determined by the interplay of intestinal absorption and renal excretion. Hypomagnesemia can occur as a result of insufficient magnesium intake, increased gastrointestinal or renal loss, or redistribution from extracellular to intracellular compartments. A number of drugs are known to cause hypomagnesemia, including proton pump inhibitors (PPIs). We report the case of a patient with symptomatic hypomagnesemia due to short bowel syndrome and PPI therapy. Investigations revealed low 24-hour urinary magnesium excretion and secondary hypocalcemia. PPI treatment was withdrawn and the patient was managed with intravenous and oral magnesium and calcium replacement. This teaching case provides an evidence-based discussion of the treatment of hypomagnesemia.

    Cosmetic products contribute to the efficacy of anti-acneic treatment. Cleaning bars without soap and lotions are to be preferred to soaps. Morning application of moisturizing creams compensate for dryness and irritation induced by topical treatment. Some of these cosmetic products may have a limited efficacy of the shiny appearance and/or acne lesions. Scrubs, abrasive sponges, masks and patches have a very limited usefulness. Make up and camouflage techniques are authorized, provided that the products have been tested non comedogenic and non acne-genic.

    Phillips, Karran A; Epstein, David H; Preston, Kenzie L

    2014-12-01

    Treatment of psychostimulant addiction has been a major, and not fully met, challenge. For opioid addiction, there is strong evidence for the effectiveness of several medications. For psychostimulants, there is no corresponding form of agonist maintenance that has met criteria for regulatory approval or generally accepted use. Stimulant-use disorders remain prevalent and can result in both short-term and long-term adverse consequences. The mainstay of treatment remains behavioral interventions. In this paper, we discuss those interventions and some promising candidates in the search for pharmacological interventions. This article is part of the Special Issue entitled 'CNS Stimulants'.

    PubMed Central

    Wood, S F

    1989-01-01

    The range of treatments for hay fever available to the general practitioner has changed considerably in recent years. New antihistamines have addressed the problem of sedation and moved towards one daily dose; nasally applied corticosteroids avoid the need for systemic steroid therapy and its potential adverse effect; and regulatory decisions have set a trend away from immunotherapy in general practice. However, knowledge about the mechanism of action of immunotherapy is increasing and new developments with improved safety profiles include allergen polymers, allergoids, oral immunotherapy and nasal immunotherapy. Choice of treatment depends, as always, on the individual circumstances of the patient and his or her disease. PMID:2556545

    Engineered Damping Treatments (EDT) that have high damping characteristics per unit volume are presented. The EDT's under consideration, consist of cellular viscoelastic damping matrices with optimally selected cell configuration, size and distribution. The cellular topology of the EDT's is designed using Computer-Aided-Design (CAD) strategies and the obtained optimal configurations will be manufactured using the state-of-the-art technology of Rapid Prototyping (RP). The EDT's are modeled using the finite element method in an attempt to determine the optimal topologies that maximize the strain energy, maximize the damping characteristics and minimize the total weight. The CAD files of the prototypes of the EDT's. The damping characteristics of the manufactured EDT's are evaluated and compared with the corresponding characteristics obtained by conventional solid damping treatments in order to emphasize the importance of using optimally configured damping treatment to achieve high damping characteristics. The presented procedures are invaluable for designing efficient damping treatments for many military and civilian structures whose vibrations and noise must be effectively controlled.

  14. Mentalization-Based Treatment

    2013-01-01

    The concept of mentalizing has captured the interest and imagination of an astonishing range of people—from psychoanalysts to neuroscientists, from child development researchers to geneticists, from existential philosophers to phenomenologists—all of whom seem to have found it useful. According to the Thompson Reuter maintained Web of Science, the use of the term in titles and abstracts of scientific papers increased from 10 to 2,750 between 1991 and 2011. Clinicians in particular have enthusiastically embraced the idea, and have put it to innovative use in their practices. Mentalization-based treatment (MBT)—making mentalizing a core focus of therapy—was initially developed for the treatment of borderline personality disorder (BPD) in routine clinical services delivered in group and individual modalities. Therapy with mentalizing as a central component is currently being developed for treatment of numerous groups, including people with antisocial personality disorder, substance abuse, eating disorders, and at-risk mothers with infants and children (A. Bateman & Fonagy, 2011). It is also being used with families and adolescents, in schools, and in managing social groups (Asen & Fonagy, 2011; Fonagy et al., 2009; Twemlow, Fonagy, & Sacco, 2005a, 2005b).

    PubMed Central

    Abdel-Raouf, N.; Al-Homaidan, A.A.; Ibraheem, I.B.M.

    2012-01-01

    Organic and inorganic substances which were released into the environment as a result of domestic, agricultural and industrial water activities lead to organic and inorganic pollution. The normal primary and secondary treatment processes of these wastewaters have been introduced in a growing number of places, in order to eliminate the easily settled materials and to oxidize the organic material present in wastewater. The final result is a clear, apparently clean effluent which is discharged into natural water bodies. This secondary effluent is, however, loaded with inorganic nitrogen and phosphorus and causes eutrophication and more long-term problems because of refractory organics and heavy metals that are discharged. Microalgae culture offers an interesting step for wastewater treatments, because they provide a tertiary biotreatment coupled with the production of potentially valuable biomass, which can be used for several purposes. Microalgae cultures offer an elegant solution to tertiary and quandary treatments due to the ability of microalgae to use inorganic nitrogen and phosphorus for their growth. And also, for their capacity to remove heavy metals, as well as some toxic organic compounds, therefore, it does not lead to secondary pollution. In the current review we will highlight on the role of micro-algae in the treatment of wastewater. PMID:24936135

  19. TOPICAL TREATMENT OF MELASMA

    PubMed Central

    Bandyopadhyay, Debabrata

    2009-01-01

    Melasma is a common hypermelanotic disorder affecting the face that is associated with considerable psychological impacts. The management of melasma is challenging and requires a long-term treatment plan. In addition to avoidance of aggravating factors like oral pills and ultraviolet exposure, topical therapy has remained the mainstay of treatment. Multiple options for topical treatment are available, of which hydroquinone (HQ) is the most commonly prescribed agent. Besides HQ, other topical agents for which varying degrees of evidence for clinical efficacy exist include azelaic acid, kojic acid, retinoids, topical steroids, glycolic acid, mequinol, and arbutin. Topical medications modify various stages of melanogenesis, the most common mode of action being inhibition of the enzyme, tyrosinase. Combination therapy is the preferred mode of treatment for the synergism and reduction of untoward effects. The most popular combination consists of HQ, a topical steroid, and retinoic acid. Prolonged HQ usage may lead to untoward effects like depigmentation and exogenous ochronosis. The search for safer alternatives has given rise to the development of many newer agents, several of them from natural sources. Well-designed controlled clinical trials are needed to clarify their role in the routine management of melasma. PMID:20101327

  7. Principled Missing Data Treatments.

    PubMed

    Lang, Kyle M; Little, Todd D

    2016-04-04

    We review a number of issues regarding missing data treatments for intervention and prevention researchers. Many of the common missing data practices in prevention research are still, unfortunately, ill-advised (e.g., use of listwise and pairwise deletion, insufficient use of auxiliary variables). Our goal is to promote better practice in the handling of missing data. We review the current state of missing data methodology and recent missing data reporting in prevention research. We describe antiquated, ad hoc missing data treatments and discuss their limitations. We discuss two modern, principled missing data treatments: multiple imputation and full information maximum likelihood, and we offer practical tips on how to best employ these methods in prevention research. The principled missing data treatments that we discuss are couched in terms of how they improve causal and statistical inference in the prevention sciences. Our recommendations are firmly grounded in missing data theory and well-validated statistical principles for handling the missing data issues that are ubiquitous in biosocial and prevention research. We augment our broad survey of missing data analysis with references to more exhaustive resources.

  8. Treatment Options for Narcolepsy.

    PubMed

    Barateau, Lucie; Lopez, Régis; Dauvilliers, Yves

    2016-05-01

    Narcolepsy type 1 and narcolepsy type 2 are central disorders of hypersomnolence. Narcolepsy type 1 is characterized by excessive daytime sleepiness and cataplexy and is associated with hypocretin-1 deficiency. On the other hand, in narcolepsy type 2, cerebrospinal fluid hypocretin-1 levels are normal and cataplexy absent. Despite major advances in our understanding of narcolepsy mechanisms, its current management is only symptomatic. Treatment options may vary from a single drug that targets several symptoms, or multiple medications that each treats a specific symptom. In recent years, narcolepsy treatment has changed with the widespread use of modafinil/armodafinil for daytime sleepiness, antidepressants (selective serotonin and dual serotonin and noradrenalin reuptake inhibitors) for cataplexy, and sodium oxybate for both symptoms. Other psychostimulants can also be used, such as methylphenidate, pitolisant and rarely amphetamines, as third-line therapy. Importantly, clinically relevant subjective and objective measures of daytime sleepiness are required to monitor the treatment efficacy and to provide guidance on whether the treatment goals are met. Associated symptoms and comorbid conditions, such as hypnagogic/hypnopompic hallucinations, sleep paralysis, disturbed nighttime sleep, unpleasant dreams, REM- and non REM-related parasomnias, depressive symptoms, overweight/obesity, and obstructive sleep apnea, should also be taken into account and managed, if required. In the near future, the efficacy of new wake-promoting drugs, anticataplectic agents, hypocretin replacement therapy and immunotherapy at the early stages of the disease should also be evaluated.

    PubMed

    Soria, A; Francès, C

    2014-09-01

    Urticaria is a common inflammatory skin disease. It is clinically defined as the occurrence of transient papular skin and/or mucosal lesions or subcutaneous lesions called angioedema. Chronic urticaria is defined as a clinical course over more than 6weeks. Different clinical forms of urticaria can coexist in the same patient. Urticaria results of mast cell activation. The diagnosis of urticaria is based on clinical examination. An allergic etiology for acute urticaria, although rare, is always to find and remove. Chronic urticaria is not allergic. Diagnosis is based on questioning and a careful clinical examination to rule out differential diagnoses. Few diagnostic tests are necessary for diagnosis and management, and are especially useful in case of doubtful diagnosis. The treatment of urticaria is symptomatic and based on anti-H1 second generation antihistamines as first-line therapy. In some chronic urticarial, antihistamines up dosing may be necessary. In the majority of patients, this treatment is sufficient to control chronic urticaria. In case of antihistamines failure, other treatment particularly immunomodulatory treatments can be offered in specialized departments.

    PubMed

    Misra, Mahesh C; Imlitemsu

    2005-01-01

    Drug treatment for various anorectal conditions has been known since ancient times. Today, modern as well as traditional drugs are being increasingly used in all grades of symptomatic haemorrhoids. These drugs (oral and local) are used as a part of conservative management or as an adjuvant to invasive outpatient procedures. Flavonoids, in the new formulation of micronised purified flavonoid fraction (MPFF) or as part of the ancient traditional medicine derivative of the Ginkgo tree, are used for relief of acute symptoms (for control of bleeding and re-bleeding in all grades of haemorrhoids). MPFF has been recommended for control of acute bleeding in patients waiting for a definitive outpatient treatment. Similarly, better known drugs such as calcium dobisilate (used in diabetic retinopathy and chronic venous insufficiency), nitrates and nifedipine have also been effective and well tolerated in the medical treatment of haemorrhoids. However, drug treatment is not aimed at curing haemorrhoids. The prime objective of drug therapy is to control the acute phase (bleeding) so that definitive therapy (banding, injection sclerotherapy, infrared photocoagulation, cryotherapy or surgery) can be scheduled at a convenient time.

    Xiong, Zilan; Roe, Jeff; Grammer, Tim; Him, Yeon-Ho; Graves, David B.

    2015-09-01

    Onychomycosis or fungal infection of the toenail or fingernail is a common affliction. Approximately 10% of the world's adult population is estimated to suffer from onychomycosis. Current treatment options such as topical creams, oral drugs, or laser treatments are generally limited by a variety of problems. We present results for an alternative onychomycosis treatment scheme using atmospheric pressure cold air plasmas. Using thinned cow hoof as a model nail material, we tested the ability of various plasma sources to act through the model nail to eradicate either bacteria or fungus deposited on the opposite side. Following 20 minute exposure to a surface microdischarge (SMD) device operating in room air, we observed a ~ 2 log reduction of E. coli. A similar result was obtained against T. rubrum after 45 min plasma treatment. NOx species concentration penetrating through the model nail as well as uptake into the nail were measured as a function of nail thickness. We propose that these plasma-generated species, or perhaps their reaction products, are responsible for at least part of the observed anti-microbial effect. We also explore the use of ultraviolet light acting in synergy with plasma-generated chemical species.

    Well-differentiated neuroendocrine tumors (NETs) of the stomach and pancreas represent 2 major subtypes of gastrointestinal NETs. Historically, there has been little consensus on the classification and management of patients with these tumor subtypes. We provide an overview of well-differentiated NETs of the stomach and pancreas and describe consensus guidelines for the treatment of patients with these malignancies. PMID:20664472

  8. Treatment-refractory anxiety; definition, risk factors, and treatment challenges.

    PubMed

    Roy-Byrne, Peter

    2015-06-01

    A sizable proportion of psychiatric patients will seek clinical evaluation and treatment for anxiety symptoms reportedly refractory to treatment. This apparent lack of response is either due to "pseudo-resistance" (a failure to have received and adhered to a recognized and effective treatment or treatments for their condition) or to true "treatment resistance." Pseudo-resistance can be due to clinician errors in selecting and delivering an appropriate treatment effectively, or to patient nonadherence to a course of treatment. True treatment resistance can be due to unrecognized exogenous anxiogenic factors (eg, caffeine overuse, sleep deprivation, use of alcohol or marijuana) or an incorrect diagnosis (eg, atypical bipolar illness, occult substance abuse, attention deficit-hyperactivity disorder). Once the above factors are eliminated, treatment should focus on combining effective medications and cognitive behavioral therapy, combining several medications (augmentation), or employing novel medications or psychotherapies not typically indicated as first-line evidence-based anxiety treatments.

    2009-09-27

    According to epidemiological studies, the prevalence of pituitary adenomas is 16.5% and the majority of them are "incidentalomas". The symptoms of pituitary disorders are often non-specific; disturbances of pituitary function, compression symptoms, hypophysis apoplexy or accidental findings may help the diagnosis. The hormonal evaluation of pituitary adenomas is different from the algorithm used in the disorders of peripheral endocrine organs. The first-line therapy of prolactinomas are the dopamine agonists, and the aims of the treatment are to normalize the prolactin level, restore fertility in child-bearing age, decrease tumor mass, save or improve the residual pituitary function and inhibit the relapse of the disease. The available dopamine agonists in Hungary are bromocriptine and quinagolide. In case of tumors with good therapeutic response, medical therapy can be withdrawn after 3-5 years; hyperprolactinemia will not recur in 2/3 of these patients. Neurosurgery is the primary therapy of GH-, ACTH-, TSH-producing and inactive adenomas. In the last decades, significant improvement has been reached in surgical procedures, resulting in low mortality rates. Acromegalic patients with unresectable tumors have a great benefit from somatostatin analog treatment. The growth hormone receptor antagonist pegvisomant is the newest modality for the treatment of acromegaly. The medical therapy of Cushing's disease is still based on the inhibition of steroid production. A new, promising somatostatin analog, pasireotide is evaluated in clinical trials. The rare TSH-producing tumor can respond to both dopamine agonist and somatostatin analog therapy. The application of conventional radiotherapy has decreased; radiotherapy is mainly used in the treatment of invasive, incurable or malignant tumors. Further studies are needed to elucidate the exact role of radiosurgery and fractionated stereotaxic irradiation in the treatment of pituitary tumors.

    Study Design Best evidence synthesis. Objective To identify, critically appraise, and synthesize literature from 1980 through 2006 on surgical interventions for neck pain alone or with radicular pain in the absence of serious pathologic disease. Summary of Background Data There have been no comprehensive systematic literature or evidence-based reviews published on this topic. Methods We systematically searched Medline for literature published from 1980 to 2006 on percutaneous and open surgical interventions for neck pain. Publications on the topic were also solicited from experts in the field. Consensus decisions were made about the scientific merit of each article; those judged to have adequate internal validity were included in our Best Evidence Synthesis. Results Of the 31,878 articles screened, 1203 studies were relevant to the Neck Pain Task Force mandate and of these, 31 regarding treatment by surgery or injections were accepted as scientifically admissible. Radiofrequency neurotomy, cervical facet injections, cervical fusion and cervical arthroplasty for neck pain without radiculopathy are not supported by current evidence. We found there is support for short-term symptomatic improvement of radicular symptoms with epidural corticosteroids. It is not clear from the evidence that long-term out comes are improved with the surgical treatment of cervical radiculopathy compared to non operative measures. However, relatively rapid and substantial symptomatic relief after surgical treatment seems to be reliably achieved. It is not evident that one open surgical technique is clearly superior to others for radiculopathy. Cervical foramenal or epidural injections are associated with relatively frequent minor adverse events (5%–20%); however, serious adverse events are very uncommon (<1%). After open surgical procedures on the cervical spine, potentially serious acute complications are seen in approximately 4% of patients. Conclusion Surgical treatment and limited

    2011-09-01

    Melasma is a common, acquired facial skin disorder, mostly involving sun-exposed areas like cheeks, forehead and upper lip. Melasma occurs in both sexes, although almost 90 percent of the affected are women. It is more common in darker skin types (Fitzpatrick skin types IV to VI) especially Hispanics/Latinos, Asians and African-Americans. The onset of the melasma is at puberty or later, with exception of darker skin types, who tend to develop this problem in the first decade of life. The etiology is still unknown, although there are a number of triggering factors related to the onset of melasma. The most important are sun-exposure and genetic factors in both sexes, while hormonal activity has more important role in females. In addition, stress and some cosmetic products and drugs containing phototoxic agents can cause outbreaks of this condition. Melasma should be treated using monotherapies or combination of therapy, mainly fixed triple or dual combinations containing hydroquinone, tretinoin, corticosteroids or azelaic acid. Modified Kligman's formula is also very effective. Above mentioned therapy regimens in combination with UVA and UVB blocking sunscreens are mostly effective in epidermal melasma. Discontinuation of the use of birth control pills, scented cosmetic products, and phototoxic drugs coupled with UV protection are also benefitial in clearing of melasma. Alternative treatment including chemical peels and glicolic acid, seem to have the best result as a second line treatment after bleaching creams. Laser treatments show limited efficacy and should rarely be used in the treatment of melasma. Combining topical agents like hydroquinone, tretinoin and a corticosteroid in addition to sun avoidance, regular use of sunscreen throughout the year and patient education is the best treatment in this difficult to treat condition.

    Gout is an inflammatory joint disease associated with deposition of monosodium urate crystals in the bones forming the joints, in periarticular tissues and in other organs. The disease is one of the most frequent causes of disability. This paper presents the case of a 57-year-old male patient treated for generalised gout. A "clinical mask" suggesting another disease was the cause of making the correct diagnosis only six years after the occurrence of the first manifestations. The patient, with high values of inflammatory markers, severe pain and advanced joint destruction, was given an aggressive anti-inflammatory treatment. The unsatisfactory effect of the conservative treatment forced the authors to perform surgical resection of the gouty nodules in the hands. After several operations the function of the hand joints operated on, appearance of the hands and the quality of the patient's life improved significantly.

    2014-09-01

    Achalasia is a primary esophageal motility disorder, which shows distinct clinical, manometric, radiologic, and pathologic features. Available treatment strategies are pharmacological, endoscopic or surgical. In the past decades preferred treatment has alternated between surgical myotomy (presently Laparoscopic Heller Myotomy [LHM]) and endoscopic balloon dilation (EBD). While surgical myotomy promises superior long-term results and significantly less retreatment, endoscopic balloon dilation is initially far less invasive and yields comparable results after redilation. Peroral Endoscopic Myotomy (POEM) aims to combine the minimal invasive approach through the mouth with the better long-term results after LHM. Initial findings in the literature point to comparable success-rates after POEM and LHM. In the literature complication rates are similar to those obtained after surgery. This new interventional technique should be subject to randomized controlled trials and compared to EBD and LHM.

  18. Surgical Treatment of Epilepsy

    2013-01-01

    Purpose of Review: This article outlines indications for neurosurgical treatment of epilepsy, describes the presurgical workup, summarizes surgical approaches, and details expected risks and benefits. Recent Findings: There is class I evidence for the efficacy of temporal lobectomy in treating intractable seizures, and accumulating documentation that successful surgical treatment reverses much of the disability, morbidity, and excess mortality of chronic epilepsy. Summary: Chronic, uncontrolled focal epilepsy causes progressive disability and increased mortality, but these can be reversed with seizure control. Vigorous efforts to stop seizures are warranted. If two well-chosen and tolerated medication trials do not achieve seizure control, an early workup for epilepsy surgery should be arranged. If this workup definitively identifies the brain region from which the seizures arise, and this region can be removed with a low risk of disabling neurologic deficits, neurosurgery will have a much better chance of stopping seizures than further medication trials.

    Parasomnias are undesirable physical or experiential events that occur in and around sleep. Treatments include reassurance in some cases, various forms of cognitive-behavioral therapy (CBT), and pharmacologic agents. Cognitive restructuring, imagery rehearsal, relaxation, hypnosis, desensitization, and anticipatory awakenings are some of the common CBT and nonpharmacologic interventions. Medications that are used belong to a wide variety of pharmacologic classes, such as alpha-blockers (prazosin), tricyclic antidepressants (imipramine and clomipramine), selective serotonin reuptake inhibitors, benzodiazepines (diazepam and clonazepam), anticonvulsants (topiramate and gabapentin), desmopressin acetate, and anticholinergic agents (oxybutynin and tolterodine). Data on efficacy are only available from randomized trials on CBT and prazosin for nightmares and on pharmacologic and alarm therapy for enuresis. No large-scale randomized trials are available to assess the efficacy of the other treatments, and most data come from anecdotal case reports, case series, or small open-label trials.

    The authors focused on the current surgical treatment of resectable gastric cancer, and significance of peri- and post-operative chemo or chemoradiation. Gastric cancer is the 4th most commonly diagnosed cancer and the second leading cause of cancer death worldwide. Surgery remains the only curative therapy, while perioperative and adjuvant chemotherapy, as well as chemoradiation, can improve outcome of resectable gastric cancer with extended lymph node dissection. More than half of radically resected gastric cancer patients relapse locally or with distant metastases, or receive the diagnosis of gastric cancer when tumor is disseminated; therefore, median survival rarely exceeds 12 mo, and 5-years survival is less than 10%. Cisplatin and fluoropyrimidine-based chemotherapy, with addition of trastuzumab in human epidermal growth factor receptor 2 positive patients, is the widely used treatment in stage IV patients fit for chemotherapy. Recent evidence supports the use of second-line chemotherapy after progression in patients with good performance status PMID:24587643

    The story of the development of tacrine began from its synthesis as an intravenous antiseptic in 1940 by Adrian Albert in Australia. In the 1970's William Summers began using tacrine in treating drug overdose coma and delirium. He felt it might have application in Alzheimer's based on work done in England by Peter Davies. In 1981, Summers et al. gave intravenous tacrine to Alzheimer's patients showed measurable improvement. Between 1981 and 1986, Summers worked with Art Kling and his group at UCLA to demonstrate usefulness of oral tacrine in treatment of Alzheimer's patients. The average length of tacrine use in 14 completing patients was 12.6 months and improvement was robust. This sparked controversy in the field. In 1993, after larger studies replicated the positive effect of tacrine, it was approved by the US Food and Drug Administration for treatment of Alzheimer's disease.

    Based on estimates from the World Health Organization (WHO), there were 8.7 million new cases of tuberculosis (TB) and 1.4 million deaths globally in 2011. In Germany, TB has become a rare disease (incidence 5.3/100,000). Therefore, experience regarding the management and treatment of TB patients is decreasing. In this review, standard therapy of TB and the drugs administered are described. Prior to initiation of therapy, a thorough patient history must be taken to evaluate the risk factors for a drug-resistant TB. In addition, bacterial confirmation via microscopic and culture analyses and phenotypic drug susceptibility testing are also recommended. Treatment of TB is always based on combined antibiotic therapy. The selection of the drugs is determined by the resistance status of the strains. For detailed recommendations refer to the current recommendations of the German Central Committee against Tuberculosis e. V. (DZK) and the German Respiratory Society (DGP).

  3. Electrocoagulation in Water Treatment

    NASA Astrophysics Data System (ADS)

    Liu, Huijuan; Zhao, Xu; Qu, Jiuhui

    Electrocoagulation (EC) is an electrochemical method of treating polluted water where sacrificial anodes corrode to release active coagulant precursors (usually aluminum or iron cations) into solution. At the cathode, gas evolves (usually as hydrogen bubbles) accompanying electrolytic reactions. EC needs simple equipments and is designable for virtually any size. It is cost effective and easily operable. Specially, the recent technical improvements combined with a growing need for small-scale water treatment facilities have led to a revaluation of EC. In this chapter, the basic principle of EC was introduced first. Following that, reactions at the electrodes and electrode assignment were reviewed; electrode passivation process and activation method were presented; comparison between electrocoagulation and chemical coagulation was performed; typical design of the EC reactors was also described; and factors affecting electrocoagulation including current density, effect of conductivity, temperature, and pH were introduced in details. Finally, application of EC in water treatment was given in details.

    2014-07-01

    Ascites is a common complication of hepatic cirrhosis and portal hypertension. Patients present systemic and splanchnic circulation disorders, which cause central hypovolemia and arterial hypotension, with the subsequent activation of vasoconstrictor systems and increased renal reabsorption of sodium and water. Approximately 5%-10% of patients present refractory ascites. Refractory ascites is considered when it is not controllable with standard dietary (sodium restriction) and diuretic (furosemide up to 160 mg a day and spironolactone up to 400mg a day) treatment or when patients present adverse effects due to diuretics that impede their administration at optimum dosages. The current therapeutic options for these patients are repeated evacuative paracentesis and the percutaneous intrahepatic portosystemic shunt. Despite these treatments, refractory ascites has a poor prognosis; patients should therefore be assessed for liver transplantation.

    Migraine is one of the most frequent disabling neurological conditions with a major impact on the patient’s quality of life. Migraine has been described as a chronic disorder that characterized with attacks. Attacks are characterized by moderate–severe, often unilateral, pulsating headache attacks, typically lasting 4 to 72 hours. Migraine remains underdiagnosed and undertreated despite advances in the understanding of its pathophysiology. This article reviews management of migraine acute pharmacological treatment. Currently, for the acute treatment of migraine attacks, non-steroidal anti-inflammatory drugs (NSAIDs) and triptans (serotonin 5HT1B/1D receptor agonists) are recommended. Before intake of NSAID and triptans, metoclopramide or domperidone is useful. In very severe attacks, subcutaneous sumatriptan is first choice. The patient should be treated early in the attack, use an adequate dose and formulation of a medication. Ideally, acute therapy should be restricted to no more than 2 to 3 days per week to avoid medication overuse.

    PubMed

    Vennewald, Irina; Klemm, Eckart

    2010-03-04

    Aspergillus and Candida spp are the most frequently isolated fungi in patients with otomycosis. The diagnosis of otitis externa relies on the patient's history, otoscopic examination under microscopic control, and imaging studies. Direct preparation of the specimens, particularly with optical brighteners, mycologic culture, and histologic examination, is very important and strongly recommended for the correct diagnosis. Patients with noninvasive fungal otitis externa should be treated with intense débridement and cleansing, and topical antifungals. Topical antifungals, such as clotrimazole, miconazole, bifonazole, ciclopiroxolamine, and tolnaftate, are potentially safe choices for the treatment of otomycosis, especially in patients with a perforated eardrum. The oral triazole drugs, itraconazole, voriconazole, and posaconazole are effective against Candida and Aspergillus, with good penetration of bone and the central nervous system. These drugs are essential in the treatment of patients with malignant fungal otitis externa complicated by mastoiditis and meningitis.

    The acute cerebellar hematoma and the subdural hematoma resent urgent surgical problems and treatment early in the clinical course should result in an excellent outcome. The subdural hematoma may be especially difficult to diagnose early, but may be suspected in patients on anticoagulant therapy or with shunze, and surgery, especially in the acute stage, should be avoided if possible. The CT scan supplemented when necessary by angiography is the diagnostic procedure of choice and will clearly demonstrate the lesions.

    2008-01-01

    Delirium occurs at rates ranging from 10% to 30% of all hospital admissions. It is a negative prognostic indicator, often leading to longer hospital stays and higher mortality. The aetiology of delirium is multifactorial and many causes have been suggested. The stress-diathesis model, which posits an interaction between the underlying vulnerability and the nature of the precipitating factor, is useful in understanding delirium. Preventing delirium is the most effective strategy for reducing its frequency and complications. Environmental strategies are valuable but are often underutilized, while remedial treatment is usually aimed at specific symptoms of delirium. Antipsychotics are the mainstay of pharmacological treatment and have been shown to be effective in treating symptoms of both hyperactive and hypoactive delirium, as well as generally improving cognition. Haloperidol is considered to be first-line treatment as it can be administered via many routes, has fewer active metabolites, limited anticholinergic effects and has a lower propensity for sedative or hypotensive effects compared with many other antipsychotics. Potential benefits of atypical compared with typical antipsychotics include the lower propensity to cause over-sedation and movement disorder. Of the second-generation antipsychotics investigated in delirium, most data support the use of risperidone and olanzapine. Other drugs (e.g. aripiprazole, quetiapine, donepezil and flumazenil) have been evaluated but data are limited. Benzodiazepines are the drugs of choice (in addition to antipsychotics) for delirium that is not controlled with an antipsychotic (and can be used alone for the treatment of alcohol and sedative hypnotic withdrawal-related delirium). Lorazepam is the benzodiazepine of choice as it has a rapid onset and shorter duration of action, a low risk of accumulation, no major active metabolites and its bioavailability is more predictable when it is administered both orally and

    1983-04-01

    These studies were initiated to determine (1) if cisplatin (cis-DDP)-induced hyperglucagonemia is related to decreased hormone degradation, (2) the relationship between impaired kidney function associated with cis-DDP nephrotoxicity and hyperglucagonemia, and (3) the contribution of cis-DDP-induced hyperglucagonemia to disturbances in glucose metabolism in male F-344 rats. Administration of 5 or 7.5, but not 2.5, mg/kg cis-DDP iv increased fasting plasma immunoreactive glucagon (IRG) concentrations. Hyperglucagonemia following cis-DDP treatment was characterized by an increase in the biologically active or true pancreatic form of IRG as well as an increase in an extrapancreatic component. cis-DDP treatment (5 mg/kg) resulted in a prolonged half-life and a reduced rate of plasma disappearance of exogenous glucagon. Reducing cis-DDP nephrotoxicity, via mannitol pretreatment, resulted in a significant reduction in total, true pancreatic, and extrapancreatic plasma IRG. Other nephrotoxicants, such as glycerol or gentamicin, also resulted in hyperglucagonemia, indicating that the effects of cis-DDP on glucagon metabolism are also characteristic of other nephrotoxicants and, therefore, may be secondary to kidney toxicity. Despite marked hyperglucagonemia following cis-DDP treatment, neither severe fasting hyperglycemia nor increased hepatic and renal gluconeogenic enzyme activity was apparent in treated animals. This apparent discrepancy cannot be attributed to glucagon resistance at the target tissue level since cis-DDP-treated animals responded appropriately to exogenous glucagon. These results indicate that hyperglucagonemia following cis-DDP treatment (1) may be related to decreased glucagon degradation associated with impaired renal function and (2) does not markedly disrupt glucose homeostasis.

    2014-08-15

    Impetigo is the most common bacterial skin infection in children two to five years of age. There are two principal types: nonbullous (70% of cases) and bullous (30% of cases). Nonbullous impetigo, or impetigo contagiosa, is caused by Staphylococcus aureus or Streptococcus pyogenes, and is characterized by honey-colored crusts on the face and extremities. Impetigo primarily affects the skin or secondarily infects insect bites, eczema, or herpetic lesions. Bullous impetigo, which is caused exclusively by S. aureus, results in large, flaccid bullae and is more likely to affect intertriginous areas. Both types usually resolve within two to three weeks without scarring, and complications are rare, with the most serious being poststreptococcal glomerulonephritis. Treatment includes topical antibiotics such as mupirocin, retapamulin, and fusidic acid. Oral antibiotic therapy can be used for impetigo with large bullae or when topical therapy is impractical. Amoxicillin/clavulanate, dicloxacillin, cephalexin, clindamycin, doxycycline, minocycline, trimethoprim/sulfamethoxazole, and macrolides are options, but penicillin is not. Natural therapies such as tea tree oil; olive, garlic, and coconut oils; and Manuka honey have been anecdotally successful, but lack sufficient evidence to recommend or dismiss them as treatment options. Treatments under development include minocycline foam and Ozenoxacin, a topical quinolone. Topical disinfectants are inferior to antibiotics and should not be used. Empiric treatment considerations have changed with the increasing prevalence of antibiotic-resistant bacteria, with methicillin-resistant S. aureus, macrolide-resistant streptococcus, and mupirocin-resistant streptococcus all documented. Fusidic acid, mupirocin, and retapamulin cover methicillin-susceptible S. aureus and streptococcal infections. Clindamycin proves helpful in suspected methicillin-resistant S. aureus infections. Trimethoprim/sulfamethoxazole covers methicillin-resistant S

    Laser treatments of various metals are studying depending on the laser wavelength, pulse time duration and shape, and fluence (laser/metal interaction regime). Low fluence excimer UV laser melting process of gold layer is shown to improve the corrosion resistance of multilayer (Au/Ni/Cu alloy) electrical contacts. For this application the homogenity of the laser beam as well as the initial Cu substrate roughness are found to be limiting parameters of the process. Carburization of Al alloy, performed in C3H6 atmosphere with a KrF laser induces the incorporation of carbon atoms over about 4 μm depth. The crystalline Al4C3 synthesized at the surface leads to a strengthening of the light Al alloy, which is of great interest for application in car industry. The study shows that diffusion of C atom in the target is possible because of a plasma presence on the surface which supports the molten bath life time and induces dissociation of the ambient gas. In the last example of laser metal surface treatment presented in that paper, a commonly used steel is treated in air with different lasers at a fluence above the plasma formation threshold. It is seen that the machining oils covering the surface before the treatment can be efficiently removed and that new compounds (nitride, carbide and oxides) are formed at the surface.

    The pharmacological treatment of obesity should be considered when cannot be achieved a 10% weight loss with diet therapy and physical activity. The drugs effective in obesity treatment may act by different mechanisms such as reduction in food intake, inhibition of fat absorption, increase of thermogenesis and stimulation of adipocyte apoptosis. At present, we only have two marketed drugs for obesity treatment. Sibutramine is an inhibitor of norepinephrine, dopamine and serotonina reuptake which inhibits food intake and increases thermogenesis. Sibutramine administration for a year can induce a weight loss of 4-7%. Its main side effects are hypertension, headache, insomnia and constipation. Orlistat is an inhibitor of pancreatic lipase which is able to block the absorption of 30% of ingested fat. Its administration induces weight loss and reduction of ulterior weight regain. Also, this drug improves hypertension dyslipdaemia and helps to prevent diabetes in 52% of cases when administered over four years. The increase in frequency of stools and interference with vitamin absorption are its main side effects. Glucagon-like peptide 1, which increases insulin sensitivity and satiety, adiponectin and PPAR-gamma agonists which reduce insulin resistance and modulates adipocyte generation are the basis for future therapeutic approaches of obesity. Phosphatase inhibitors induce PPAR-gamma phosphorylation and UCP-1 expression leading to an increase in thermogenesis and reduction in appetite.

    COPD treatment begins with smoking cessation and influenza and pneumococcal vaccines. Bronchodilators are indicated when dyspnea on exertion is reported (usually, FEV1 < 80% predicted). On-demand short-acting agents are chosen when dyspnea is intermittent, daily long-acting agents are administered once dyspnea occurs in daily life activities. In all cases, anticholinergics and beta2 agonists can be associated when one class is not sufficiently effective. In patients with FEV1 < 50% predicted (budesonide-formoterol) or 60% predicted (fluticasone-salmeterol), repeated exacerbations and symptoms despite maintenance bronchodilators, fixed associations are indicated. When a handicap persists on pharmacological treatment, respiratory rehabilitation centered on education and exercise training has to be proposed. Care for COPD has to integrate treatment of comorbidities such as cardio-vascular diseases, anxiety-depression, malnutrition, muscle dysfunction, osteoporosis, anemia ... Ongoing research aims at identifying new therapeutic targets, focusing on inflammation, remodeling, protease-antiprotease balance, oxidative stress, lung regeneration/repair and mucus production.

    2008-08-01

    Although compulsive buying is receiving increasing attention in research, it is largely ignored in clinical practice. Compulsive buying disorder (CBD) is defined as excessive and mostly senseless spending or excessive shopping impulses that cause marked distress, interfere with social or occupational functioning, and often results in financial problems. It is currently conceptualized as an "impulse control disorder not otherwise specified" (ICD-10 F63.9). CBD is associated with significant psychiatric co-morbidity particularly mood and anxiety disorders, obsessive-compulsive disorders, binge eating disorder, substance use disorders, personality disorders, and other impulse control disorders. Previous research indicates that many compulsive buyers also suffer from compulsive hoarding. There is no evidence-based treatment approach for CBD and treatment research on this topic is limited. Open label trials suggest that antidepressants could improve compulsive buying. However, small randomized controlled trials failed to demonstrate significant improvement over Placebo and the high placebo-response rate prevents any definitive statement on the efficacy of antidepressants. Two controlled cognitive-behavioral therapy (CBT) trials reported that group CBT is significantly more effective compared to waiting list control groups in the treatment of compulsive buying. Clinical and therapeutic implications are discussed.

    Pinals, R S

    1992-01-01

    Current pharmacotherapy for osteoarthritis (OA) is aimed at relief of pain and functional disability. Although an inflammatory component may be found in some cases, there is little evidence that anti-inflammatory drugs commonly used in the treatment of OA provide more relief than simple analgesics. A growing body of knowledge about the pathophysiology of OA now offers opportunities to develop interventions aimed at retarding the progressive degeneration of articular cartilage. This is a function of an imbalance between cartilage matrix synthesis and breakdown. New and experimental treatments include oral, parenteral, and intra-articular agents, some of which are chemicals and others biological products. Their modes of action have generally not been established in humans, but may be inferred from in vitro culture systems and animal models. These mechanisms include inhibition of synovial cell-derived cytokines and chondrocyte-derived degradative enzymes, inactivation of superoxide free radicals, stimulation of matrix synthesis, and enhancement of synovial fluid lubrication. Many of these treatments have been shown to provide short- or long-term symptomatic improvement in clinical trials. Protection of cartilage or promotion of repair has been demonstrated in animal studies, but not convincingly in human OA studies.

    The mystery of Traditional Chinese Medicine has been attracting people for years. Acupuncture, ranked among the most common services of Complementary and Alternative Medicine, has recently gained a lot of interest in the scientific world. Contemporary researchers have been continuously trying to shed light on its possible mechanism of action in human organism. Numerous studies pertaining to acupuncture’s application in cancer symptoms or treatment-related side effects management have already been published. Moreover, since the modern idea of acupuncture’s immunomodulating effect seems to be promising, scientists have propounded a concept of its potential application as part of direct anti-tumor therapy. In our previous study we summarized possible use of acupuncture in management of cancer symptoms and treatment-related ailments, such as chemotherapy-induced nausea and vomiting, pain, xerostomia, vasomotor symptoms, neutropenia, fatigue, anxiety, insomnia, lymphoedema after mastectomy and peripheral neuropathy. This article reviews the studies concerning acupuncture as a possible tool in modern anticancer treatment. PMID:28239282

    Giardia lamblia is both the most common intestinal parasite in the United States and a frequent cause of diarrheal illness throughout the world. In spite of its recognition as an important human pathogen, there have been relatively few agents used in therapy. This paper discusses each class of drugs used in treatment, along with their mechanism of action, in vitro and clinical efficacy, and side effects and contraindications. Recommendations are made for the preferred treatment in different clinical situations. The greatest clinical experience is with the nitroimidazole drugs, i.e., metronidazole, tinidazole, and ornidazole, which are highly effective. A 5- to 7-day course of metronidazole can be expected to cure over 90% of individuals, and a single dose of tinidazole or ornidazole will cure a similar number. Quinacrine, which is no longer produced in the United States, has excellent efficacy but may be poorly tolerated, especially in children. Furazolidone is an effective alternative but must be administered four times a day for 7 to 10 days. Paromomycin may be used during early pregnancy, because it is not systematically absorbed, but it is not always effective. Patients who have resistant infection can usually be cured by a prolonged course of treatment with a combination of a nitroimidazole with quinacrine. PMID:11148005

    1994-09-01

    Several subcutaneous and deep-seated mycoses are either observed more frequently in the tropical areas or are restricted to certain regions within the tropics. These mycoses include sporotichosis, chromoblastomycosis, entomophthoromycosis, eumycetoma, lobomycosis, and paracoccidioidomycosis. In sporotrichosis and paracoccidioidomycosis, therapy often results in either complete resolution or marked improvement. For decades sporotrichosis has been treated successfully with potassium iodide, but recently the triazole compounds, especially itraconazole, have proved effective and free of major side effects. The usual therapy for paracoccidioidomycosis is sulfonamides or amphotericin B; the former requires prolonged treatment, whereas the latter causes a significant degree of toxicity. Various azole derivatives (ketoconazole, fluconazole, saperconazole, and itraconazole) allow shorter treatment courses, can be given orally, and are more effective. Presently, itraconazole is the drug of choice. Chromoblastomycosis is a difficult condition to treat, especially if it is caused by Fonsecaea pedrosoi. Several therapeutic approaches have been used, including heat, surgery, cryotherapy, thiabendazole, amphotericin B combined with flucytosine, and azole derivatives, but their success has been modest. A 65% response rate has been obtained with itraconazole given for periods of 6 to 19 months; in limited trials, saperconazole appears to be more effective and requires shorter treatment courses. Only a few patients with eumycetoma respond to therapy; 70% of patients with Madurella mycetomatis respond to prolonged treatment with ketoconazole. Griseofulvin has been tried in nonresponders with partial success. Limited data in patients with Fusarium species eumycetoma indicate good responses to itraconazole. Eumycetoma caused by Pseudallescheria boydii or Acremonium species has been refractory to therapy. Therapy of entomophthoromycosis is also difficult because the diagnosis is usually

    PubMed

    Hain, Timothy C; Uddin, Mohammed

    2003-01-01

    This review discusses the physiology and pharmacological treatment of vertigo and related disorders. Classes of medications useful in the treatment of vertigo include anticholinergics, antihistamines, benzodiazepines, calcium channel antagonists and dopamine receptor antagonists. These medications often have multiple actions. They may modify the intensity of symptoms (e.g. vestibular suppressants) or they may affect the underlying disease process (e.g. calcium channel antagonists in the case of vestibular migraine). Most of these agents, particularly those that are sedating, also have a potential to modulate the rate of compensation for vestibular damage. This consideration has become more relevant in recent years, as vestibular rehabilitation physical therapy is now often recommended in an attempt to promote compensation. Accordingly, therapy of vertigo is optimised when the prescriber has detailed knowledge of the pharmacology of medications being administered as well as the precise actions being sought. There are four broad causes of vertigo, for which specific regimens of drug therapy can be tailored. Otological vertigo includes disorders of the inner ear such as Ménière's disease, vestibular neuritis, benign paroxysmal positional vertigo (BPPV) and bilateral vestibular paresis. In both Ménière's disease and vestibular neuritis, vestibular suppressants such as anticholinergics and benzodiazepines are used. In Ménière's disease, salt restriction and diuretics are used in an attempt to prevent flare-ups. In vestibular neuritis, only brief use of vestibular suppressants is now recommended. Drug treatments are not presently recommended for BPPV and bilateral vestibular paresis, but physical therapy treatment can be very useful in both. Central vertigo includes entities such as vertigo associated with migraine and certain strokes. Prophylactic agents (L-channel calcium channel antagonists, tricyclic antidepressants, beta-blockers) are the mainstay of treatment

    The present article reviewed some of the treatment modalities for restoring anterior teeth in the primary dentition. It divided the treatment types into three classifications based on the severity of the carious lesions or injury. Treatments that are not usually found in current textbooks were outlined and commented upon. It was suggested that dentists have to consider a wide range of treatment options since factors such as the age of the child, ability to cope with treatment and cost of treatment have to be taken into account.

    Severe infections are uncommon following orthopedic surgery, yet they can be frustrating for the veterinarian and owner to treat and can result in devastating consequences for the patient. This article reviews the common causes for postoperative infection, reviews established treatment, and introduces newer methods for treatment and control. A thorough understanding of the pathogenesis, application of appropriate diagnostic procedures, the institution of aggressive treatment regimens, with adherence to established principles, will often result in satisfactory outcomes even with severe orthopedic infections. For those more refractory to treatment, the use of newer treatment methods, specifically locally implantable materials for sustained release of antimicrobials can improve success in the treatment of these more difficult cases.

  12. Ayahuasca and cancer treatment

    2013-01-01

    Objectives: Comprehensively review the evidence regarding the use of ayahuasca, an Amerindian medicine traditionally used to treat many different illnesses and diseases, to treat some types of cancer. Methods: An in-depth review of the literature was conducted using PubMed, books, institutional magazines, conferences and online texts in nonprofessional sources regarding the biomedical knowledge about ayahuasca in general with a specific focus in its possible relations to the treatment of cancer. Results: At least nine case reports regarding the use of ayahuasca in the treatment of prostate, brain, ovarian, uterine, stomach, breast, and colon cancers were found. Several of these were considered improvements, one case was considered worse, and one case was rated as difficult to evaluate. A theoretical model is presented which explains these effects at the cellular, molecular, and psychosocial levels. Particular attention is given to ayahuasca’s pharmacological effects through the activity of N,N-dimethyltryptamine at intracellular sigma-1 receptors. The effects of other components of ayahuasca, such as harmine, tetrahydroharmine, and harmaline, are also considered. Conclusion: The proposed model, based on the molecular and cellular biology of ayahuasca’s known active components and the available clinical reports, suggests that these accounts may have consistent biological underpinnings. Further study of ayahuasca’s possible antitumor effects is important because cancer patients continue to seek out this traditional medicine. Consequently, based on the social and anthropological observations of the use of this brew, suggestions are provided for further research into the safety and efficacy of ayahuasca as a possible medicinal aid in the treatment of cancer.

    2011-06-15

    Alzheimer disease is the most common form of dementia, affecting nearly one-half [corrected] of Americans older than 85 years. It is characterized by progressive memory loss and cognitive decline. Amyloid plaque accumulation, neurofibrillary tau tangles, and depletion of acetylcholine are among the pathologic manifestations of Alzheimer disease. Although there are no proven modalities for preventing Alzheimer disease, hypertension treatment, omega-3 fatty acid supplementation, physical activity, and cognitive engagement demonstrate modest potential. Acetylcholinesterase inhibitors are first-line medications for the treatment of Alzheimer disease, and are associated with mild improvements in cognitive function, behavior, and activities of daily living; however, the clinical relevance of these effects is unclear. The most common adverse effects of acetylcholinesterase inhibitors are nausea, vomiting, diarrhea, dizziness, confusion, and cardiac arrhythmias. Short-term use of the N-methyl-D-aspartate receptor antagonist memantine can modestly improve measures of cognition, behavior, and activities of daily living in patients with moderate to severe Alzheimer disease. Memantine can also be used in combination with acetylcholinesterase inhibitors. Memantine is generally well tolerated, but whether its benefits produce clinically meaningful improvement is controversial. Although N-methyl-D-aspartate receptor antagonists and acetylcholinesterase inhibitors can slow the progression of Alzheimer disease, no pharmacologic agents can reverse the progression. Atypical antipsychotics can improve some behavioral symptoms, but have been associated with increased mortality rates in older patients with dementia. There is conflicting evidence about the benefit of selegiline, testosterone, and ginkgo for the treatment of Alzheimer disease. There is no evidence supporting the beneficial effects of vitamin E, estrogen, or nonsteroidal anti-inflammatory drug therapy.

    The main clinical types of epilepsy and their treatment are described. The treatment of choice in petit mal epilepsy is trimethadione (Trimedone) 0.3 g., three to six times a day, or acetazolamide (Diamox) 125-250 mg., three to four times a day. Phenobarbital is usually given as well to prevent grand mal seizures. Diphenylhydantoin sodium (Dilantin Sodium), 100 mg., and/or phenobarbital, 30-100 mg., three to four times a day, is recommended in patients with focal and grand mal epilepsy. Psychomotor automatisms are a form of focal seizure. Primidone (Mysoline), in doses of 125-250 mg. two to three times a day, is a very useful anticonvulsant in patients with myoclonic features, psychomotor automatisms and grand mal seizures. Primidone should be started in small doses. Drug reactions, especially cerebellar ataxia in the case of diphenylhydantoin and blood dyscrasias in the case of some drugs, should be recognized. Excessive drowsiness can be avoided by proper dosage and proper timing of drug administration. Patients should be seen regularly at least two to three times a year. The objective of treatment is to achieve optimum control of seizures by using the appropriate drug in adequate dosage. Social adaptation is good in the majority of patients, who should be encouraged to carry on their life independently, usually free to marry and have children. Attention to special occupational hazards has to be considered. Education of employers and employees is often necessary. Special work arrangements are occasionally indicated for selected patients. Patients should be seizure-free for two to three years before permission is given to drive an automobile. PMID:13969008

    Vaginal or vulvovaginal atrophy is a widespread but poorly recognized condition of peri- and post-menopausal women. It causes urogenital symptoms of dryness, reduced lubrication, itching, burning, irritable bladder symptoms and painful intercourse. This impacts quality of life and sexual health, but increases with time rather than reduces, as with most other menopausal symptoms. With early identification, treatments can improve these symptoms and reverse the physical changes. However, when embedded, bladder and sexual changes have occurred and these may be more difficult to remedy. Therefore, it is important to educate both healthcare professionals and women about these symptoms and advise on the range of interventions available.

    The effective treatment of acute (myeloblastic and lymphoblastic) leukaemias depends on the induction of remissions as well as on the maintenance of these remissions. Whereas the use of anthracyclines and of cytosine arabinoside in different combinations notably increased the rate of induction of remissions, their maintenance was less successful until now. We present a scheme using, beside MTX and 6-MP, modified COAP regimes periodically every 3 months. The follow-up of 26 patients treated in this way is encouraging since nearly one third remained in full haematological remission after 3 years of observation.

About all the other kinds of alopecia, recommendations for therapy are still based upon the literature review, expert opinion, personal experience, expected adverse effects, and some pragmatic considerations such as the cost and the patient's compliance. Cicatricial alopecia is one of the most difficult challenges for dermatologists, because it is uncommon, its etiopathogenesis is not completely understood and there is no best therapy approach.

    Melasma, a hypermelanosis of the face, is a common skin problem of middle-aged women of all racial groups, especially with dark complexion. Its precise etio-pathogenesis is evasive, genetic influences, exposure to sunlight, pregnancy, oral contraceptives, estrogen-progesterone therapies, thyroid dysfunction, cosmetics, and drugs have been proposed. Centro-facial, malar, and mandibular are well-recognized. Epidermal pigmentation appears brown/black, while dermal is blue in color, and can be distinguished by Wood's lamp illumination. The difference may be inapparent with mixed type of melasma in skin types V and VI. An increase in melanin in epidermis: basal and suprabasal layers and/or dermis is the prime defect. There is an increased expression of tyrosinase related protein-1 involved in eumelanin synthesis. The use of broad-spectrum sunscreen is important, lightening agents like retinoic acid (tretinoin), azelaic acid, and combination therapies containing hydroquinone, tretinoin, and corticosteroids, have been used in the treatment of melasma, and are thought to have increased efficacy as compared with monotherapy. Quasi-drugs, placental extracts, ellagic acid, chamomilla extract, butylresorcinol, tranexamic acid, methoxy potassium salicylate, adenosine monophosphate disodium salt, dipropyl-biphenyl-2,2'-diol, (4-hydroxyphenyl)-2-butanol, and tranexamic acid cetyl ester hydrochloride, in addition to kojic and ascorbic acid have been used.

    At the No Treatment Day School, less than 15% of students used the dormitory during the school week. Located in the heart of a reservation and serving local students, the K-12 school enrolled over 1,000 students. The site received Therapeutic Residential Model funding for the 2001-2002 school year. Initial evaluation of this site found an array of daunting problems throughout the school structure and functioning. There were some successes, including implementation of the Morningside reading program in the elementary school and some response from the community to the comprehensive evaluation report which provided an overview of the situation to policy-makers and community members. However instability in the system and a mid-year change in leadership complicated the process of implementation. By the end of the first year, it was clear that the feasibility of the original proposal was questionable and that an overhaul of the school's system and culture was necessary before a Therapeutic Residential Model could be implemented or significant change could come about. Therapeutic Residential Model funding was terminated at the end of the school year. As there was no substantial implementation of a Therapeutic Residential Model program, data gathered were utilized as representing a naturally occurring control or minimal treatment site.

    Systemic lupus erithematosus (SLE) is a multiorganic inflammatory disease characterized by a significant morbidity and mortality related not just to disease evolution but also to therapeutic side effects. Sixty percent of SLE patients develop renal disease related to lupus. Moreover, several studies report that lupus nephritis is an important predictor of both renal impairment and global mortality in these patients. In lupus nephritis, the renal biopsy still represents a cornerstone for both histological grading and therapeutical management. Several classification schemes for lupus nephritis based mainly on morphological parameters have been proposed so far. In the WHO grading system the most severe form of lupus nephritis is the diffuse proliferative lupus nephritis or lupus nephritis class IV. In fact, several authors have documented an invariable course to end stage renal failure in these patients, in the absence of specific therapy. Despite the considerable improvement observed since the introduction of corticosteroid and cyclophosphamide treatment, a significant number of patients still present an incomplete response to therapy. Moreover, even in the cases of good response to therapy adverse events related to the treatment such as infertility, hemorrhagic cystitis or increased susceptibility to infection frequently supervenes.

    Despite the potential risks to the mother and fetus caused by immunosuppressive drugs, uneventful pregnancies are now frequent among transplant recipients. Although there is no apparent increase in the type or incidence of malformations in the newborns or evidence of graft dysfunction, pregnancy-related complications, including premature termination and low birth weight, may be more frequent. To prevent graft rejection due to the increased immunologic reactivity of the transplant recipient during pregnancy, it is reasonable to wait 2 years after transplantation before conception, to have stable graft function and to be on low drug doses for maintenance immunosuppression. Among the immunosuppressive agents, corticosteroids may induce a number of treatment-related complications, including diabetes and osteoporosis; however, the incidence of fetal malformations during corticosteroid treatment is about 3.5%, a value close to that of the general population. Among immunosuppressive antibodies, no evidence of developmental toxicity has been demonstrated with basiliximab. On the contrary, some concerns have been raised about azathioprine, since its use has been associated with fetal abnormalities in animals; however, clinical data so far have indicated only a small teratogenic risk. Therefore, immunosuppressive therapy with selected drugs and antibodies does not apparently increase the risk of birth defects and may be continued in pregnancy. Finally, although breast-feeding is not recommended, because of drug transfer into maternal milk, the available clinical data do not support this limitation because of the low amount of drug absorbed by the infant and the absence of clinical toxicity in published case reports.

  7. Treatment of Huntington's disease.

    Huntington's disease (HD) is a dominantly inherited progressive neurological disease characterized by chorea, an involuntary brief movement that tends to flow between body regions. HD is typically diagnosed based on clinical findings in the setting of a family history and may be confirmed with genetic testing. Predictive testing is available to family members at risk, but only experienced clinicians should perform the counseling and testing. Multiple areas of the brain degenerate, mainly involving the neurotransmitters dopamine, glutamate, and γ-aminobutyric acid. Although pharmacotherapies theoretically target these neurotransmitters, few well-conducted trials for symptomatic interventions have yielded positive results and current treatments have focused on the motor aspects of HD. Tetrabenazine is a dopamine-depleting agent that may be one of the more effective agents for reducing chorea, although it has a risk of potentially serious adverse effects. Some newer neuroleptic agents, such as olanzapine and aripiprazole, may have adequate efficacy with a more favorable adverse effect profile than older neuroleptic agents for treating chorea and psychosis. There are no current treatments to change the course of HD, but education and symptomatic therapies can be effective tools for clinicians to use with patients and families affected by HD.

  8. Radon Treatment Controversy

    In spite of long traditions, treatments utilizing radon-rich air or water have not been unequivocally embraced by modern medicine. The objective of this work is to examine factors that contribute to this continuing controversy. While the exact mechanism of radon's effect on human body is not completely understood, recent advances in radiobiology offer new insights into biochemical processes occurring at low-level exposures to ionizing radiation. Medical evidence and patients' testimonials regarding effectiveness of radon spa treatments of various ailments, most notably rheumatoid arthritis are accumulating worldwide. They challenge the premise of the Linear-No-Threshold (LNT) theory that the dose-effect response is the same per unit dose regardless of the total dose. Historically, such inference overshadowed scientific inquiries into the low-dose region and lead to a popular belief that no amount of radiation can be good. Fortunately, the LNT theory, which lacks any scientific basis, did not remain unchallenged. As the reviewed literature suggests, a paradigm shift, reflected in the consideration of hormetic effects at low-doses, is gaining momentum in the scientific community worldwide. The impetus comes from significant evidence of adaptive and stimulatory effects of low-levels of radiation on human immune system. PMID:18648641

    Malaria is the tropical disease most commonly imported into the UK, with 1500-2000 cases reported each year, and 10-20 deaths. Approximately three-quarters of reported malaria cases in the UK are caused by Plasmodium falciparum, which is capable of invading a high proportion of red blood cells and rapidly leading to severe or life-threatening multi-organ disease. Most non-falciparum malaria cases are caused by Plasmodium vivax; a few cases are caused by the other two species of Plasmodium: Plasmodium ovale or Plasmodium malariae. Mixed infections with more than 1 species of parasite can occur; they commonly involve P. falciparum with the attendant risks of severe malaria. Management of malaria depends on awareness of the diagnosis and on performing the correct diagnostic tests: the diagnosis cannot be excluded until 3 blood specimens have been examined by an experienced microscopist. There are no typical clinical features of malaria, even fever is not invariably present. The optimum diagnostic procedure is examination of thick and thin blood films by an expert to detect and speciate the malarial parasites; P. falciparum malaria can be diagnosed almost as accurately using rapid diagnostic tests (RDTs) which detect plasmodial antigens or enzymes, although RDTs for other Plasmodium species are not as reliable. The treatment of choice for non-falciparum malaria is a 3-day course of oral chloroquine, to which only a limited proportion of P. vivax strains have gained resistance. Dormant parasites (hypnozoites) persist in the liver after treatment of P. vivax or P. ovale infection: the only currently effective drug for eradication of hypnozoites is primaquine. This must be avoided or given with caution under expert supervision in patients with glucose-6-phosphate dehydrogenase deficiency (G6PD), in whom it may cause severe haemolysis. Uncomplicated P. falciparum malaria can be treated orally with quinine, atovaquone plus proguanil (Malarone) or co-artemether (Riamet

    Pharmacotherapy with levodopa for Parkinson's disease provides symptomatic benefit, but fluctuations in (or loss of) response may eventually occur. Dopamine agonists are also helpful and, when taken with low doses of levodopa, often provide sustained benefit with fewer side effects; novel agonists and new methods for their administration are therefore under study. Other therapeutic strategies are being explored, including the use of type B monoamine oxidase inhibitors to reduce the metabolic breakdown of dopamine, catechol-O-methyltransferase inhibitors to retard the breakdown of levodopa, norepinephrine precursors to compensate for deficiency of this neurotransmitter, glutamate antagonists to counteract the effects of the subthalamic nucleus, and various neurotrophic factors to influence dopaminergic nigrostriatal cells. Surgical procedures involving pallidotomy are sometimes helpful. Those involving cerebral transplantation of adrenal medullary or fetal mesencephalic tissue have yielded mixed results; benefits may relate to the presence of growth factors in the transplanted tissue. The transplantation of genetically engineered cell lines will probably become the optimal transplantation procedure. The cause of Parkinson's disease may relate to oxidant stress and the generation of free radicals. It is not clear whether treatment with selegiline hydrochloride (a type B monoamine oxidase inhibitor) delays the progression of Parkinson's disease, because the drug also exerts a mild symptomatic effect. Daily treatment with vitamin E (a scavenger of free radicals) does not influence disease progression, perhaps because of limited penetration into the brain. Images PMID:7975571

    Solid formation in filtered leachates and wash solutions was seen in five of the six sludges treated by Enhanced Sludge Washing. Solid formation in process solutions takes a variety of forms: very fine particles, larger particulate solids, solids floating in solution like egg whites, gels, crystals, and coatings on sample containers. A gel-like material that formed in a filtered leachate from Enhanced Sludge Washing of Hanford T-104 sludge was identified as natrophosphate, Na{sub 7}(PO{sub 4}){sub 2}F{center_dot}19H{sub 2}O. A particulate material that formed in a filtered caustic leachate from Hanford SX-113 sludge contained sodium and silicon. This could be any of a host of sodium silicates in the NaOH-SiO{sub 2}-H{sub 2}O system. Acidic treatment of Hanford B-202 sludge with 1 M, 3 M, and 6 M HNO{sub 3} sequential leaching resulted in complete dissolution at 75 C, but not at ambient temperature. This treatment resulted in the formation of solids in filtered leachates. Analyses of the solids revealed that a gel material contained silica with some potassium, calcium, iron, and manganese. Two phases were embedded in the gel. One was barium sulfate. The other could not be identified, but it was determined that the only metal it contained was bismuth.

    OBJECTIVE To review the evidence regarding treatment of herpes zoster (HZ) in the short-term, focusing on the prevention of postherpetic neuralgia (PHN). QUALITY OF EVIDENCE The evidence relating to treatment of HZ is derived mainly from randomized controlled trials (level I evidence). MAIN MESSAGE Antiviral drugs might have some effect on the severity of acute pain and on the duration of skin lesions. Corticosteroids also alleviate acute pain. Oral antiviral medication reduces the risk of eye complications in patients with ophthalmic HZ. There is no convincing evidence that antiviral medication reduces the risk of PHN. Some studies, however, have shown that famciclovir and valacyclovir shorten the duration of PHN. The effectiveness of amitriptyline or cutaneous and percutaneous interventions in preventing PHN has not been proven. CONCLUSION Oral antiviral drugs should be prescribed to elderly HZ patients with high risk of PHN. Moreover, these drugs should be prescribed to all patients at the first signs of ophthalmic HZ, irrespective of age or severity of symptoms. PMID:18337531

    A range of treatment options are available in rosacea, which include several topical (mainly metronidazole, azelaic acid, other antibiotics, sulfur, retinoids) and oral drugs (mainly tetracyclines, metronidazole, macrolides). In some cases, the first choice is a systemic therapy because patients may have sensitive skin and topical medications can be irritant. Isotretinoin can be used in resistant cases of rosacea. Unfortunately, the majority of studies on rosacea treatments are at high or unclear risk of bias. A recent Cochrane review found that only topical metronidazole, azelaic acid, and oral doxycycline (40 mg) had some evidence to support their effectiveness in moderate to severe rosacea and concluded that further well-designed, adequately-powered randomised controlled trials are required. In our practice, we evaluate our patients for the presence of two possible triggers, Helicobacter pylori infection and small intestinal bacterial overgrowth. When they are present we use adapted antibiotic protocols. If not, we use oral metronidazole or oral tetracycline to treat papulopustolar rosacea. We also look for Demodex folliculorum infestation. When Demodex concentration is higher than 5/cm(2) we use topical crotamiton 10% or metronidazole.

    Treatment of refractory ulcerative colitis (UC) is a common clinical challenge. In either acute or chronic refractory UC, the disease may continue to remain active, even though the patient is on appropriate therapy. It is important to reassess and characterize the patient's disease before adding new medications to the current medical regimen. After determining the current extent and severity of the UC—ruling out other causes of bloody diarrhea and determining what complications are present—new treatment approaches can then be started. It is critical to first optimize oral 5-aminosalicylic acid (5-ASA) therapy combined with rectal 5-ASA or corticosteroid suppositories, plus corticosteroid or 5-ASA enemas or foam preparations. Oral or intravenous corticosteroids are appropriate to use if needed, but alternative approaches must be used for long-term maintenance. 6-Mercaptopurine (6-MP) or azathioprine can be very helpful for severe chronic refractory UC. In those patients who do not respond to 5-ASA medications, corticosteroids, and 6-MP or azathioprine, infliximab offers an important approach for induction and maintenance of remission for refractory chronic ulcerative colitis as well as for select cases of refractory acute UC. Cyclosporine use is an alternative medical approach for the refractory acute UC patient. Colectomy with ileal pouch-anal anastomosis remains a valuable option for the refractory chronic or acute UC patient, because it can provide both a “cure” for the disease, as well as eliminate ineffective medications with their associated side effects.

    Hirsutism is usually the result of an underlying adrenal, ovarian, or central endocrine abnormality mainly due to polycystic ovary syndrome but may also be idiopathic or drug induced. The aim of medical treatment of hirsutism is to rectify any causal hormonal balance, slow down or stop excessive hair growth, and improve the aesthetic appearance of hirsutism, thereby positively affecting the patient's quality of life. Today, for the majority of women, a monotherapy with oral contraceptives that have antiandrogenic activity is recommended as a first-line treatment for hirsutism. Combining an oral contraceptive pill with an antiandrogen is recommended if clinical improvement of hirsutism is insufficient after 6-9 months' monotherapy. In women who present with hirsutism, hyperandrogenism, and insulin resistance, insulin sensitizers are effective for the hirsutism as well as the hyperinsulinemia, hyperandrogenism, and infertility but there is no convincing evidence that they are effective for hirsutism alone. Topical eflornithine is a medical therapy that can be a useful adjuvant for hirsutism when used in conjunction with systemic medications or with laser/photoepilation.

    Objective Chronic cough remains a challenging condition, especially in cases where it persists despite comprehensive medical management. For these particular patients, there appears to be an emerging role for behavior modification therapy. We report a series of patients with refractory chronic cough to assess if there is any benefit of adding behavioral therapy to their treatment regimen. Study Design A case series with planned chart review of patients treated for chronic cough. Setting The review was performed with an outpatient electronic health record system at a tertiary care center. Subjects and Methods The charts of all patients treated for chronic cough by a single laryngologist over a 30-month period were analyzed. Patients' response to treatment and rate of cough improvement were assessed for those with refractory chronic cough who underwent behavior modification therapy. Results Thirty-eight patients with chronic cough were initially treated empirically for the most common causes of cough, of which 32% experienced improvement. Nineteen patients who did not significantly improve with medical management underwent behavior modification therapy with a speech-language pathologist. Of these patients, 84% experienced resolution or marked improvement of their symptoms. Conclusion Behavioral therapy may be underutilized in practice and could lead to improvement of otherwise recalcitrant cough.

    The purpose of this paper is to analyze the current evolutions on nanotechnology and its applications on cancer theragnostics.Rapid advances and emerging technologies in nanotechnology are having a profound impact on cancer treatment. Applications of nanotechnology, which include liposomes, nanoparticles, polymeric micelles, dendrimers, nanocantilever, carbon nanotubes and quantum dots have significantly revolutionized cancer theragnostics. From a pharmaceutical viewpoint, it is critical that the biodistribution of active agents has to be controlled as much as possible. This aspect is vital in order to assure the proper efficiency and safety of the anticancer agents. These biocompatible nanocomposites provide specific biochemical interactions with receptors expressed on the surface of cancer cells. With passive or active targeting strategies, an increased intracellular concentration of drugs can be achieved in cancer cells , while normal cells are being protected from the drug simultaneously. Thus, nanotechnology restricts the extent of the adverse effects of the anticancer therapy. Treatment for metastatic breast cancer, sarcoma in AIDS patients, ovarian and lung cancer is already on market or under final phases of many clinical trials, showing remarkable results. As nanotechnology is perfected, side effects due to normal cell damage will decrease, leading to better results and lengthening patient's survival.

    Objective Despite the undisputed effectiveness of agonist maintenance for opioid dependence, individuals can remain on waitlists for months, during which they are at significant risk for morbidity and mortality. To mitigate these risks, the Food and Drug Administration in 1993 approved interim treatment, involving daily medication + emergency counseling only, when only a waitlist is otherwise available. We review the published research in the 20 years since the approval of interim opioid treatment. Methods A literature search was conducted to identify all randomized trials evaluating the efficacy of interim treatment for opioid-dependent patients awaiting comprehensive treatment. Results Interim opioid treatment has been evaluated in four controlled trials to date. In three, interim treatment was compared to waitlist or placebo control conditions and produced greater outcomes on measures of illicit opioid use, retention, criminality and likelihood of entry into comprehensive treatment. In the fourth, interim treatment was compared to standard methadone maintenance and produced comparable outcomes in illicit opioid use, retention and criminal activity. Conclusions Interim treatment significantly reduces patient and societal risks when conventional treatment is unavailable. Further research is needed to examine the generality of these findings, further enhance outcomes, and identify the patient characteristics which predict treatment response. PMID:25937593

    Pheochromocytoma is a tumor derived from chromaffin tissue, which secretes catecholamines. Today, about 90 percent of patients with this tumor are cured by surgical procedures. In 8 to 15 percent of patients with this tumor there is unresectable, recurrent or metastatic disease, which causes significant morbidity and mortality. The natural history of metastatic disease includes long-term survivors; many, however, die early of disseminated disease. The most common site of metastatic lesions is the skeleton. Palliation for these lesions can often be achieved with the use of radiation therapy. Other sites are, in general, less responsive to radiation therapy. Chemotherapy has been used in combination with radiation therapy, but the results generally have been disappointing. Chemotherapy with doxorubicin hydrochloride and cyclophosphamide in combination with radiation therapy has provided good palliation for skeletal disease for about five months, when disease progression was again noted. Further information is needed concerning the optimal chemotherapeutic treatment of this unusual tumor. PMID:629048

    The final products of the ethanol industry are alcoholic beverages, industrial ethanol and biofuels. They are produced by the same production process, which includes fermentation and distillation of raw materials which come from plant biomass. At the end of the distillation process a waste effluent is obtained called vinasse or stillage. The direct disposal of stillages on land or in groundwater (rivers, streams or lakes), or even for the direct irrigation of crops, pollutes the environment due to their high organic contents, dissolved solids and many other compounds which are toxic or could be contaminants under certain environmental conditions. This work reviews the characterization of vinasses from different feedstock sources and the main treatments for conditioning the soluble solids of vinasses before their disposal.

    1992-01-01

    In locations where total solar energy inputs average 400 langeleys or more, microscopic algae, grown in properly designed ponds, can contribute significantly and economically to wastewater treatment. While growing, microalgae produce an abundance of oxygen for microbial and biochemical oxidation of organics and other reduced compounds and for odor control. Microalgae also accelerate the inactivation of disease bacteria and parasitic ova by increasing water temperature and pH. Microalgae remove significant amounts of nitrogen and phosphorus and adsorb most polyvalent metals, including those that are toxic. After growth in properly designed paddle wheel mixed high rate ponds, microalgae settle readily, leaving a supernatant free of most pollutants. Such effluents are suitable for irrigation of ornamental plants, crops not eaten raw, aquaculture, and grounwater recharge. The settled and concentrated microalgae may be used for fertilizer, for fermentation to methane, or, assuming no toxicity, for fish, bivalve, or animal feed.

    Proper classification of patients into diffuse cutaneous and limited cutaneous subsets and the anticipation of complications are the keys to the management of subjects with systemic sclerosis (scleroderma). Patients with early diffuse disease and rapidly progressive skin thickening are at highest risk of developing serious disease of the internal organs (intestine, lung, heart, kidney) and should be considered for disease modifying treatment. The targets of the disease and sites of possible intervention are vascular endothelium (vasoprotective agents), mononuclear cell subsets (immunosuppressive agents), and fibroblasts (colchicine, D-penicillamine). A number of new agents with sound scientific rationale are currently undergoing therapeutic trials. Much can be done to improve the lifestyle of those with scleroderma. The most dramatic recent development is the ability to reverse kidney disease by the prompt use of angiotensin converting enzyme inhibitors and modern methods of renal dialysis and transplantation. Scleroderma is not a hopeless disease. PMID:1750801

    Chagas' disease (ChD), caused by the protozoa Trypanosoma cruzi (T. cruzi), was discovered and described by the Brazilian physician Carlos Chagas in 1909. After a century of original description, trypanosomiasis still brings much misery to humanity and is classified as a neglected tropical disease prevalent in underdeveloped countries, particularly in South America. It is an increasing worldwide problem due to the number of cases in endemic areas and the migration of infected subjects to more developed regions, mainly North America and Europe. Despite its importance, chronic chagas cardiomyopathy (CCC) pathophysiology is yet poorly understood, and independently of its social, clinical, and epidemiological importance, the therapeutic approach of CCC is still transposed from the knowledge acquired from other cardiomyopathies. Therefore, the objective of this review is to describe the treatment of Chagas cardiomyopathy with emphasis on its peculiarities. PMID:24350293

    Chronic obstructive pulmonary disease (COPD) is a major health problem worldwide. It is characterised by chronic inflammation in the lungs that leads to progressive chronic airflow obstruction. The main strategy for treating COPD is control of the chronic inflammation. However, current anti-inflammatory treatments fail to prevent disease progression. New long-acting bronchodilators and their combinations are currently under development. Research has been focused on identifying the key inflammatory regulators. CXCR2 antagonists inhibit neutrophilic inflammation; inhibitors of phosphodiesterase-4 (PDE4), p38 mitogen-activated protein kinase (p38), Janus kinases and IL-6 have also shown some promising effects. There is an emerging need for identification of key modulators of the oxidative stress-regulated corticosteroid function aiming the development of monotherapies which will resolve any side effects issues currently faced.

Staff at Oak Ridge National Laboratory (ORNL) are recovering and treating the liquid (supernatant) portions of Melton Valley Storage Tank (MVST) waste in a hot cell to separate and remove the radionuclides. Batch tests will be used to evaluate and select the most promising materials for supernatant treatment to reduce the amount of waste for final disposal. Small column tests will be made on selected sorbents to verify the batch data and to obtain additional data for process design. Efforts will be made to obtain samples of tank supernatant from Hanford for comparison.

  4. [Treatment of tension headache].

    Schoenen, J

    2000-01-01

    The scientific basis of tension- type headache suffers from the lack of precise pathophysiological knowledge and the heterogenecity of this disorder. Treatment of acute tension-type headache episodes is more effective with an NSAIDs (ibuprofen 400-800mg, naproxen 550-825mg, ketoprofen 50-75mg) than with aspirin or paracetamol. Caffein containing preparations of NSAIDs are slightly superior, but should not be taken frequently to avoid headache chronification. For chronic tension-type headache, relaxation therapies with EMG biofeedback and tricyclics have about the same efficacy rate of 40-50p.100. Physical therapy and acupuncture are in general less effective. There is thus clearly a need for better strategies, e.g. combination of available therapies and novel approaches.

    Dermatological diseases, such as dysesthesia syndromes, stasis dermatoses, and hyperhidrosis are difficult to treat due to their complex etiologies. Current theories suggest these diseases are caused by physiological imbalances, such as nerve impingement, localized tissue congestion, and impaired autonomic regulation. Osteopathic manipulative therapy targets these physiological dysfunctions and may serve as a beneficial therapeutic option. Osteopathic manipulative therapy techniques include high velocity low amplitude, muscle energy, counterstrain, myofascial release, craniosacral, and lymphatic drainage. An osteopathic manipulative therapy technique is chosen based on its physiological target for a particular disease. Osteopathic manipulative therapy may be useful alone or in combination with standard therapeutic options. However, due to the lack of standardized trials supporting the efficacy of osteopathic manipulative therapy treatment for dermatological disease, randomized, well-controlled studies are necessary to confirm its therapeutic value.

    1979-01-01

    An organic waste containing at least one element selected from the group consisting of strontium, cesium, iodine and ruthenium is treated to achieve a substantial reduction in the volume of the waste and provide for fixation of the selected element in an inert salt. The method of treatment comprises introducing the organic waste and a source of oxygen into a molten salt bath maintained at an elevated temperature to produce solid and gaseous reaction products. The gaseous reaction products comprise carbon dioxide and water vapor, and the solid reaction products comprise the inorganic ash constituents of the organic waste and the selected element which is retained in the molten salt. The molten salt bath comprises one or more alkali metal carbonates, and may optionally include from 1 to about 25 wt.% of an alkali metal sulfate.

    The effects of microbial fouling on treatment bed (TB) performance are being studied. Fouling of activated carbon (AC) and ion exchange resins (IEX) by live and devitalized bacteria can cause decreased capacity for selected sorbates with AC and IEX TB. More data are needed on organic species removal in the trace region of solute sorption isotherms. TB colonization was prevented by nonclassical chemical disinfectant compositions (quaternary ammonium resins) applied in suitable configurations. Recently, the protection of carbon beds via direct disinfectant impregnation has shown promise. Effects (of impregnation) upon bed sorption/removal characteristics are to be studied with representative contaminants. The potential need to remove solutes added or produced during water disinfection and/or TB microbiological control must be investigated.

    2004-03-01

    Autism is a chronic and lifelong pervasive developmental disorder for which there is yet no effective cure, and medical management remains a major challenge for clinicians. In spite of the possible similarities with conditions that have an established pharmacotherapy, and despite improvements in some associated "problematic behaviors" following the use of available medications, effective medical treatment for the core symptoms involving language and social cognition remains elusive. The purpose of the present article is to review current biologic knowledge about autism in an attempt to correlate clinical trials with known mechanisms of disease. In addition, the need for controlled studies and for the creation of homogeneous subgroups of patients based on clinical and genetic characteristics is emphasized. The application of molecular genetic investigations and pharmacogenetics in the diagnostic work-up of autistic patients can lead to more effective individualized medical care.

    The treatment of postmenopausal osteoporosis relies on management of some risk factors for fracture, e.g., risk factors for falls, improvement of calcium and vitamin D intake, and on various medications. All elderly women with calcium and vitamin D deficiency should receive calcium and vitamin D supplements. Estrogen replacement therapy should not longer be used to prevent or treat postmenopausal osteoporosis, owing to its poor long-term risk/benefit ratio. Raloxifene, biphosphonates (alendronate, risedronate) are well tolerated compounds with proven anti-fracture efficacy. Teriparatide is a new bone forming agent to treat severe osteoporosis. Strontium ranelate is a new drug also reducing the risk of fractures that should be available soon.

    Untargeted metabolic profiling was employed to characterize metabolomic changes associated with 'Granny Smith' apple superficial scald development following 1-MCP or DPA treatment. Partial least-squares discriminant analyses were used to link metabolites with scald, postharvest treatments, and storage duration. Models revealed metabolomic differentiation between untreated controls and fruit treated with DPA or 1-MCP within 1 week following storage initiation. Metabolic divergence between controls and DPA-treated fruit after 4 weeks of storage preceded scald symptom development by 2 months. alpha-Farnesene oxidation products with known associations to scald, including conjugated trienols, 6-methyl-5-hepten-2-one, and 6-methyl-5-hepten-2-ol, were associated with presymptomatic as well as scalded control fruit. Likewise, a large group of putative triterpenoids with mass spectral features similar to those of ursolic acid and beta-sitosterol were associated with control fruit and scald. Results demonstrate that extensive metabolomic changes associated with scald precede actual symptom development.

  11. The treatment of malaria.

    White, N J

    1996-09-12

    Increasing drug resistance in Plasmodium falciparum and a resurgence of malaria in tropical areas have effected a change in treatment of malaria in the last two decades. Symptoms of malaria are fever, chills, headache, and malaise. The prognosis worsens as the parasite counts, counts of mature parasites, and counts of neutrophils containing pigment increase. Treatment depends on severity, age of patient, degree of background immunity, likely pattern of susceptibility to antimalarial drugs, and the cost and availability of drugs. Chloroquine should be used for P. vivax, P. malariae, and P. ovale. P. vivax has shown high resistance to chloroquine in Oceania, however. Primaquine may be needed to treat P. vivax and P. ovale to rid the body of hypnozoites that survive in the liver. Chloroquine can treat P. falciparum infections acquired in North Africa, Central America north of the Panama Canal, Haiti, or the Middle East but not in most of Africa and some parts of Asia and South America. In areas of low grade resistance to chloroquine, amodiaquine can be used to effectively treat falciparum malaria. A combination of sulfadoxine-pyrimethamine is responsive to falciparum infections with high grade resistance to chloroquine. Mefloquine, halofantrine, or quinine with tetracycline can be used to treat multidrug-resistant P. falciparum. Derivatives of artemisinin obtained from qinghao or sweet wormwood developed as pharmaceuticals in China are the most rapidly acting of all antimalarial drugs. Children tend to tolerate antimalarial drugs well. Children who weigh less than 15 kg should not be given mefloquine. Health workers should not prescribe primaquine to pregnant women or newborns due to the risk of hemolysis. Chloroquine, sulfadoxine-pyrimethamine, quinine, and quinidine can be safely given in therapeutic doses throughout pregnancy. Clinical manifestations of severe malaria are hypoglycemia, convulsions, severe anemia, acute renal failure, jaundice, pulmonary edema

    Nine patients with primary hyperoxaluria have been followed regularly for 1 to 11 years, and their treatment and progress are discussed in relation to the known natural history of the disease. 6 of them probably have the usual form of primary hyperoxaluria associated with increased glycollic acid excretion, while 3 who are sibs have the recently described variant associated with L-glyceric aciduria and normal glycollic acid excretion. All 9 patients have been on regimens designed to increase the urinary solubility of calcium oxalate, with or without the simultaneous lowering of urinary calcium and raising of urinary phosphate excretions. 8 patients have been treated for 1½-7½ years (average duration 4 years) with oral magnesium hydroxide, and 2 patients have been treated with sodium phosphate. One of the latter was changed after 3½ years to magnesium hydroxide and the other has been on sodium phosphate combined with a low calcium diet and cellulose phosphate continuously for 5½ years. 2, not at first diagnosed as hyperoxalurics, were first given sodium bicarbonate for their presumably secondary renal tubular acidosis. The over-all progress of the whole group is felt to have been better than could be expected from the known natural history of primary hyperoxaluria. They average 4¼ years on treatment during 5 years of our observation and all remain clinically well after an average of 9½ years since the onset of their first symptoms. Results warrant the recommendation that, until reliable means are available to decrease oxalate over-production, affected patients should be treated continuously with magnesium hydroxide. A more final opinion must await many more years of follow-up. The failure of several attempts to lower urinary oxalate excretion in these patients is also reported.

    What if neurofeedback or other types of neurotechnological treatment, by itself or in combination with behavioral treatment, could achieve a successful "rewiring" of the psychopath's brain? Imagine that such treatments exist and that they provide a better long-term risk-minimizing strategy compared to imprisonment. Would it be ethical to offer such treatments as a condition of probation, parole, or (early) prison release? In this paper, I argue that it can be ethical to offer effective, non-invasive neurotechnological treatments to offenders as a condition of probation, parole, or (early) prison release provided that: (1) the status quo is in no way cruel, inhuman, degrading, or in some other way wrong, (2) the treatment option is in no way cruel, inhuman, degrading, or in some other way wrong, (3) the treatment is in the best interests of the offender, and (4) the offender gives his/her informed consent.

    2017-01-01

    With a continuing increase in the number of tattoos performed worldwide, the need to treat tattoo complications is growing. Earlier treatments of chronic inflammatory tattoo reactions were dominated by a medical approach, or with no active intervention. In this chapter, we will address modern surgical approaches applied to situations when medical treatment is inefficient and lasers are not applicable. Dermatome shaving is positioned as first-line treatment of allergic tattoo reactions and also indicated in a number of other tattoo reactions, supplemented with excision in selected cases. The methods allow fundamental treatment with removal of the culprit pigment from the dermis. The different instruments, surgical methods, and treatment schedules are reviewed, and a guide to surgeons is presented. Postoperative treatments and the long-term outcomes are described in detail. An algorithm on specialist treatment and follow-up of tattoo reactions, which can be practiced in other countries, is presented.

    2015-01-01

    Tobacco use is associated with 5 million deaths per year worldwide and is considered as one of the leading causes of premature death. Comprehensive tobacco control programs can significantly reduce the prevalence of tobacco use. An important component of a comprehensive program is the provision of treatment for tobacco addiction. Treatment involves targeting multiple aspects of addiction including the underlying neurobiology and behavioral processes. Furthermore, building an infrastructure in health systems that encourage and facilitate cessation and expanding the accessibility of treatments are necessary. While current pharmacological and behavioral treatments are effective in improving cessation success, the rate of relapse to smoking remains high, demonstrating the strong addictive nature of nicotine. The future of treatment resides in better patient matching to treatment, combination or novel medications, and conceptualizing nicotine addiction as a chronic disorder which may require long-term treatment.

    Modern pharmacological treatments for anxiety disorders are safer and more tolerable than they were 30 years ago. Unfortunately, treatment efficacy and duration have not improved in most cases despite a greater understanding of the pathophysiology of anxiety. Moreover, innovative treatments have not reached the market despite billions of research dollars invested in drug development. In reviewing the literature on current treatments, we argue that evidence-based practice would benefit from better research on the causes of incomplete treatment response as well as the comparative efficacy of drug combinations and sequencing. We also survey two broad approaches to the development of innovative anxiety treatments: the continued development of drugs based on specific neuroreceptors and the pharmacological manipulation of fear-related memory. We highlight directions for future research, as neither of these approaches is ready for routine clinical use. PMID:23023162

    This report presents the results of a study of nonthermal treatment technologies. The study consisted of a systematic assessment of five nonthermal treatment alternatives. The treatment alternatives consist of widely varying technologies for safely destroying the hazardous organic components, reducing the volume, and preparing for final disposal of the contact-handled mixed low-level waste (MLLW) currently stored in the US Department of Energy complex. The alternatives considered were innovative nonthermal treatments for organic liquids and sludges, process residue, soil and debris. Vacuum desorption or various washing approaches are considered for treatment of soil, residue and debris. Organic destruction methods include mediated electrochemical oxidation, catalytic wet oxidation, and acid digestion. Other methods studied included stabilization technologies and mercury separation of treatment residues. This study is a companion to the integrated thermal treatment study which examined 19 alternatives for thermal treatment of MLLW waste. The quantities and physical and chemical compositions of the input waste are based on the inventory database developed by the US Department of Energy. The Integrated Nonthermal Treatment Systems (INTS) systems were evaluated using the same waste input (2,927 pounds per hour) as the Integrated Thermal Treatment Systems (ITTS). 48 refs., 68 figs., 37 tabs.

    Electrochemical treatment is an alternative modality for tumor treatment based on the application of a low intensity direct electric current to the tumor tissue through two or more platinum electrodes placed within the tumor zone or in the surrounding areas. This treatment is noted for its great effectiveness, minimal invasiveness and local effect. Several studies have been conducted worldwide to evaluate the antitumoral effect of this therapy. In all these studies a variety of biochemical and physiological responses of tumors to the applied treatment have been obtained. By this reason, researchers have suggested various mechanisms to explain how direct electric current destroys tumor cells. Although, it is generally accepted this treatment induces electrolysis, electroosmosis and electroporation in tumoral tissues. However, action mechanism of this alternative modality on the tumor tissue is not well understood. Although the principle of Electrochemical treatment is simple, a standardized method is not yet available. The mechanism by which Electrochemical treatment affects tumor growth and survival may represent more complex process. The present work analyzes the latest and most important research done on the electrochemical treatment of tumors. We conclude with our point of view about the destruction mechanism features of this alternative therapy. Also, we suggest some mechanisms and strategies from the thermodynamic point of view for this therapy. In the area of Electrochemical treatment of cancer this tool has been exploited very little and much work remains to be done. Electrochemical treatment constitutes a good therapeutic option for patients that have failed the conventional oncology methods. PMID:23592904

    Achilles tendinopathy affects athletes, recreational exercisers and even inactive people. The pathology is not inflammatory; it is a failed healing response. The source of pain in tendinopathy could be related to the neurovascular ingrowth seen in the tendon's response to injury. The treatment of Achilles tendinopathy is primarily conservative with an array of effective treatment options now available to the primary care practitioner. If conservative treatment is not successful, then surgery relieves pain in the majority of cases. Directing a patient through the algorithm presented here will maximise positive treatment outcomes.

    2004-01-01

    This paper discusses the development of a solid waste treatment system that has been designed for a Mars transit exploration mission. The technology described is an energy-efficient lyophilization technique that is designed to recover water from spacecraft solid wastes. Candidate wastes include feces, concentrated brines from water processors, and other solid wastes that contain free water. The system is designed to operate as a stand-alone process or to be integrated into the International Space Station Waste Collection System. In the lyophilization process, water in an aqueous waste is frozen and then sublimed, separating the waste into a dried solid material and liquid water. The sublimed water is then condensed in a solid ice phase and then melted to generate a liquid product. In the subject system the waste solids are contained within a 0.2 micron bio-guard bag and after drying are removed from the system and stored in a secondary container. This technology is ideally suited to applications such as the Mars Reference Mission, where water recovery rates approaching 100% are desirable but production of CO2 is not. The system is designed to minimize power consumption through the use of thermoelectric heat pumps. The results of preliminary testing of a prototype system and testing of the final configuration are provided. A mathematical model of the system is also described.

    Urosepsis is one of the most frequent sepsis entities. Mortality from urosepsis is nowadays mostly lower than from other entities. Sepsis syndrome is pathophysiologically characterized by a generalized infection and immune dysregulation. Exogenous microbiological and active or passive endogenous factors released from body cells initiate and accompany the immune dysregulation. Diagnosis and therapy of urosepsis need to be instigated as early as possible (within the first hour), in order to prevent cell and tissue damage in the early phase. For this reason a series of measures is started, aimed at achieving early control of the focus of infection, providing antibiotic treatment, and stabilizing respiratory and cardiovascular function in order to optimize tissue oxygenation. A significant clinical problem ensues due to increasing antibiotic resistance mainly of enterobacteria. The choice of antibiotic therefore is made on the basis of local antibiotic resistance statistics. Dosage is determined on an individual basis, as well as according to current pharmacokinetic/pharmacodynamic knowledge. The intensive care of the septic patient needs to be started as early as on patient admission and, where necessary, continued on the intensive care ward.

    2016-06-01

    Dravet syndrome is among the most challenging electroclinical syndromes. There is a high likelihood of recurrent status epilepticus; seizures are medically refractory; and patients have multiple co-morbidities, including intellectual disability, behaviour and sleep problems, and crouch gait. Additionally, they are at significant risk of sudden unexplained death. This review will focus predominantly on the prophylactic medical management of seizures, addressing both first-line therapies (valproate and clobazam) as well as second-line (stiripentol, topiramate, ketogenic diet) or later options (levetiracetam, bromides, vagus nerve stimulation). Sodium channel agents-including carbamazepine, oxcarbazepine, phenytoin and lamotrigine-should be avoided, as they typically exacerbate seizures. Several agents in development may show promise, specifically fenfluramine and cannabidiol, but they need further evaluation in randomized, controlled trials. In addition to prophylactic treatment, all patients need home-rescue medication and a status epilepticus protocol that can be carried out in their local hospital. Families must be counselled on non-pharmacologic strategies to reduce seizure risk, including avoidance of triggers that commonly induce seizures (including hyperthermia, flashing lights and patterns). In addition to addressing seizures, holistic care for a patient with Dravet syndrome must involve a multidisciplinary team that includes specialists in physical, occupational and speech therapy, neuropsychology, social work and physical medicine.

    Methane is a significant GHG, and substantial reservoirs are vulnerable to instability due to AGW. Excursions, from permafrost and clathrates especially, act a positive feedback to AGW. Existing concentrations of well-mixed atmospheric methane substantially exceed pre-industrial levels. Various geoengineering methods are herein proposed for containment of methane, and/or accelerated oxidation to CO2 (a gas with a lower GWP over all timescales). A basic qualitative analysis of each technique is undertaken, to direct further study. Consideration is also given to the potential capacity of each technique to treat the total likely excursions of methane expected as a result of AGW. Proposed techniques: Section 0 SRM (comparison option) Section 1 Pre-emptive treatment of methane reservoirs Soil heating (polytunnels, heat pumps); Soil aeration; Mining of clathrates; Burning of clathrates Section 2 Remediation of aquatic methane excursions Lake sealing; Mixing of aquatic strata; Bubble capture; Lake aeration; Biological oxidation in aquatic environments Section 3 Remediation of concentrated atmospheric methane Regenerative thermal oxidation; Electrical ignition; Thermal ignition; Using incendiary munitions Section 4 Remediation of diffuse atmospheric methane Thermal oxidation by concentrated solar power; Compression ignition; Chemical degradation Assessment criteria: Infrastructure/implementation cost; Energy cost; Expected efficacy; Complexity/development path; Environmental impacts; Potential for CCS

    Experimental procedures and current state-of-the-art are presented for laser surface treating methods such as alloying, cladding, grain refining, and transformation hardening using a cw CO2 laser. Microstructural and x-ray analyses of the treated surfaces indicate that a laser beam can locally enhance surface properties. Laser alloying offers the possibility to selectively modify a low cost workpiece surface so that it has the desired high quality surface properties characteristic of high performance alloys. Laser cladding offers feasibility to apply high melting cladding alloys on low melting workpieces, to reduce the amount of dilution of cladding alloy with the workpieces, and the potential to apply dense ceramic claddings to metallic workpieces. Laser grain refining offers potential to either minimize or eliminate surface defects such as inclusions, intermetallic compounds, and pores, and to provide a refined grain structure. Laser transformation hardening provides the treated workpieces with a hard martensitic surface that has compressive stresses for enhanced fatigue life; in addition, reduction in wear rate of treated surfaces is achieved. This experimental study indicates that the use of lasers for surface treatment has several limitations. Further studies will provide better understanding for maximum utilization of laser surface treating processes.

    1. The treatment of osteoarthritis is currently purely symptomatic. To enable rational therapy, careful clinical assessment is necessary to identify the origin of symptoms. Often, effective therapy can result from a biomechanical approach such as surgery, orthotics, physiotherapy and dieting. If drugs are required, there is little evidence that the current over-reliance on non-steroidal anti-inflammatory drugs (NSAIDs) is justified. Full dose regular paracetamol should be the first line of analgesic therapy. In the majority of patients, simple analgesics are probably as effective as NSAIDs. If NSAIDs are used it is necessary to review regularly their use and to be aware of potential toxicity. 2. Many alternative strategies of pain management such as topical preparations, intra-articular steroid injections, acupuncture, radiosynovectomy, transcutaneous nerve stimulation and anti-depressants, may be effective but their precise place in the armamentarium is not yet fully established. 3. The realisation that osteoarthritis is not a passive 'wear and tear' phenomenon but an active process that may be potentially modified, has led to interest in 'chondroprotective' agents, which may beneficially affect the osteoarthritic process. To date there are no convincing data available that such agents are, in fact, chondroprotective in humans. PMID:1576063

    The prevalence of idiopathic nephrolithiasis is increasing in rich countries. Dietary manipulation could contribute to the prevention of both its first appearance and the recurrence of the disease. The target of dietary treatment is to decrease the “urinary lithogenic risk factors” such as low urine volume, hypercalciuria, hyperoxaluria, hyperuricosuria, hyperphosphaturia, hypocitraturia, hypomagnesuria and excessively alkaline or acid urinary pH. Due to the lack of randomized controlled trials focused on this problem, there is not ample evidence to confidently recommend dietary changes. Despite this, numerous recent and past experiences support modification of diet as having a primary role in the prevention of nephrolithiasis. In particular, it is recommended to limit animal protein and salt intake, to consume milk and derivatives in amounts corresponding to calcium intake of about 1200 mg/day and to assume fiber (40 g/day), vegetables and fruit daily avoiding foods with high oxalate content. Furthermore, vitamin C intake not exceeding 1500 mg/day plays a protective role as well as avoiding vitamin B6 deficiency and abstaining, if possible, from vitamin D supplements. Lastly, it is recommended to drink enough water to bring the urinary volume up to at least 2 L/day and, as much as possible, to use fresh or frozen products rather than prepacked or precooked foods which are often too rich in sodium chloride.

    2006-10-01

    Mandibular prognathism (MP) or skeletal Class III malocclusion with a prognathic mandible is one of the most severe maxillofacial deformities. Facial growth modification can be an effective method of resolving skeletal Class III jaw discrepancies in growing children with dentofacial orthopedic appliances including the chincup, face mask, maxillary protraction combined with chincup traction and the Fränkel functional regulator III appliance. Orthognathic surgery in conjunction with orthodontic treatment is required for the correction of adult MP. The two most commonly applied surgical procedures to correct MP are sagittal split ramus osteotomy (SSRO) and intraoral vertical ramus osteotomy. Both procedures are suitable for patients in whom a desirable occlusal relationship can be obtained with a setback of the mandible, and each has its own advantages and disadvantages. In bilateral SSRO, the intentional ostectomy of the posterior part of the distal segment can offer long-term positioned stability. This may be attributable to reduction of tension in the pterygomasseteric sling that applies force in the posterior mandible. While various environmental factors have been found to contribute to the development of MP, heredity plays a substantial role. The relative contributions of genetic and environmental components in the etiology of MP are unclear. The recent identification of the genetic susceptibilities to MP constitutes the first step toward understanding the molecular pathogenesis of MP. Further studies in molecular biology are needed to identify the gene-environment interactions associated with the phenotypic diversity of MP and the heterogenic developmental mechanisms thought to be responsible for them.

    2003-08-01

    The treatment of Acanthamoeba keratitis has now been possible since the first successful therapy developed in the mid 1980s with a combination of propamidine 0.1% (Brolene) and neomycin 1%. However, only half the patients responded to this regimen as the cysts were often resistant to neomycin and relatively insensitive to propamidine. This led to research for better therapy, culminating in the mid 1990s with research in Glasgow demonstrating much increased effectiveness with use of the biguanide chlorhexidine 0.02% and in London and Bristol for similar effectiveness with the polymeric polyhexamethylene biguanide (PHMB) 0.02%. Both biguanides were combined with propamidine for enhanced effectiveness but were also shown to be effective as monotherapy. While this therapy inactivates the trophozoites and cysts in Acanthamoeba keratitis in the majority of patients (approximately 90%), there have been notable failures particularly when presentation is late with deep stromal infection. Additional highly acanthamoebicidal drugs are needed that can penetrate the stroma for synergistic action. This role may be taken up by certain antineoplastic drugs, such as alkylphosphocholine-1 (Miltefosine), that also have antiprotozoal activity.

    In a controlled field trial, 178 dairy cows with chronic endometritis and at least 21 days in lactation were randomly assigned to four different treatment groups: prostaglandin F2alpha intramuscularly (PG, 5 mg dinoprost (5 ml Dinolytic), n = 51), intrauterine antibiotics (AB; 400 mg ampicillin + 800 oxacillin (20 ml Totocillin), n = 49), intrauterine antiseptics (AS; 100 ml 4% Lotagen, n = 50); control (C, no initial treatment, n = 28). Before treatment, uterine swabs for bacteriologic examination and blood samples for determination of serum progesterone concentrations were collected. Two weeks following the first treatment, cows were reexamined. In case no clinical cure was diagnosed, treatment was repeated and control cows were treated for the first time with one of the three treatments mentioned above. The four treatment groups did not differ with respect to the clinical cure or reproductive performance. Therefore, factors that might have an influence on clinical cure and fertility were evaluated. With increasing duration of lactation, the clinical cure after a single treatment increased significantly over all treatment groups from 59.5% (treatment before day 42 postpartum) to 79.6% (treatment following day 42 postpartum) (P < 0.05). Within the PG group, a statistically significantly higher cure rate after a single treatment and first service conception rate and a lower pregnancy index were obtained when the treatment was performed following day 42 postpartum (P < 0.05). This was not the case in the other treatment groups. A retarded involution of the uterus based on the size had a negative effect on clinical cure over all groups (first treatment clinical cure: 68.2% (small uteri) vs 44.4% (large uteri); P < 0.05). Within groups, this effect was also detected, but only as a trend (P > 0.05). Isolation of Arcanobacterium (A.) pyogenes negatively influenced first treatment clinical cure over all treatment groups (79.0% vs 31.5%) and within treatment groups (P < 0

  10. Treatment of mastitis during lactation

    PubMed Central

    2009-01-01

    Treatment of mastitis should be based on bacteriological diagnosis and take national and international guidelines on prudent use of antimicrobials into account. In acute mastitis, where bacteriological diagnosis is not available, treatment should be initiated based on herd data and personal experience. Rapid bacteriological diagnosis would facilitate the proper selection of the antimicrobial. Treating subclinical mastitis with antimicrobials during lactation is seldom economical, because of high treatment costs and generally poor efficacy. All mastitis treatment should be evidence-based, i.e., the efficacy of each product and treatment length should be demonstrated by scientific studies. Use of on-farm written protocols for mastitis treatment promotes a judicious use of antimicrobials and reduces the use of antimicrobials. PMID:22081939

  11. Rosacea: new and emerging treatments.

    PubMed

    Moustafa, Farah A; Sandoval, Laura F; Feldman, Steven R

    2014-09-01

    Rosacea is a chronic inflammatory skin condition that negatively impacts patients' quality of life. We sought to review important aspects of the pathogenesis of rosacea and the role of new treatment options in its management. New, emerging treatments show promise; however, quality randomized controlled trials for many of these drugs are lacking. Brimonidine tartrate is an effective newly approved treatment for erythematotelangiectatic rosacea. Topical oxymetazoline has potential for the treatment of erythematotelangiectatic rosacea, with efficacy described in case reports and randomized controlled trials currently underway. Both oral and topical ivermectin have been studied for the treatment of papulopustular rosacea, both showing benefit; however, only topical ivermectin 1 % cream has been studied in randomized controlled trials. As our understanding of the etiology of rosacea continues to evolve, so will our options for therapeutic interventions. Further studies need to be performed to assess the long-term safety and efficacy of these treatments.

  12. Current treatment of Graves' disease

    SciTech Connect

    Harada, T.; Shimaoka, K.; Mimura, T.; Ito, K.

    1987-04-01

    In this review we have described the rationale for the appropriate treatment of patients with Graves' disease. Because the etiology of this disorder remains obscure, its management remains controversial. Since antithyroid drugs and radioiodine became readily available in the early 1950s, they have been widely used for the treatment of thyrotoxicosis, and the number of cases treated surgically has markedly decreased. However, almost four decades of experience have disclosed an unexpectedly high incidence of delayed hypothyroidism after radioiodine treatment and a low remission rate after antithyroid therapy. As a result, surgery is again being advocated as the treatment of choice. The three modalities of treatment have different advantages and disadvantages, and selection of treatment is of importance. In principle, we believe that for most patients a subtotal thyroidectomy should be performed after the patient has been rendered euthyroid by antithyroid drugs. We attempt to leave a thyroid remnant of 6 to 8 gm.36 references.

  13. Nonpharmacologic treatments in psychodermatology.

    PubMed

    Fried, Richard G

    2002-01-01

    The author believes that psychocutaneous medicine has indeed come of age and is being incorporated into mainstream medical practice. Patients presenting to dermatologists today are more sophisticated and are frequently dissatisfied with traditional medical therapies. They actively seek alternative approaches and adjuncts to standard treatments. In contrast to many other "alternative" (or) "holistic" treatments offered through non-medical venues, dermatologists can assure their patients that controlled studies support the efficacy of psychocutaneous techniques in improving many dermatologic conditions. Psoriasis, rosacea, herpes simplex, body dysmorphic disorder, acne, eczema, urticaria, neurotic excoriations, excoriated acne, trichotillomania, dysesthetic syndromes, and delusions parasitosis are included in this incomplete list. The author believes it is helpful for both the patient and therapist to define concrete and realistic goals for psychocutaneous intervention. Concrete observable or measurable goals can help the patient and clinician gauge therapeutic progress and success. Specifically, goals can include reduction in pruritus (rating severity from 1-10), decreased scratching activity, decreased plaque extent or thickness, decreased number of urticarial plaques, decreased flushing, decreased anxiety, decreased anger, decreased social embarrassment, decreased social withdrawal, and improved sleep. More global goals can include an improved sense of well-being, increased sense of control, and enhanced acceptance of some of the inevitable aspects of a given skin disease. Cure should never be a goal, because most disorders amenable to psychocutaneous techniques are chronic in nature; thus, cure as an endpoint would only lead to disappointment. The author encourages dermatologists to align themselves with what he euphemistically calls "a skin-emotion specialist." The skin-emotion specialist may be a psychiatrist, psychologist, social worker, biofeedback therapist

    Calik, Michael W.

    2016-01-01

    Objective To review the efficacy of current treatment options for adults with obstructive sleep apnea (OSA). Methods Review of the literature. Results OSA, characterized by repetitive ≥ 10-second interruptions (apnea) or reductions (hypopnea) in airflow, is initiated by partial or complete collapse in the upper airway despite respiratory effort. When left untreated, OSA is associated with comorbid conditions, such as cardiovascular and metabolic diseases. The current “gold standard” treatment for OSA is continuous positive air pressure (CPAP), which pneumatically stabilizes the upper airways. CPAP has proven efficacy and potential cost savings via decreases in health comorbidities and/or motor-vehicle crashes. However, CPAP treatment is not well-tolerated due to various side effects, and adherence among OSA subjects can be as low as 50% in certain populations. Other treatment options for OSA include improving CPAP tolerability, increasing CPAP adherence through patient interventions, weight loss/exercise, positional therapy, nasal expiratory positive airway pressure, oral pressure therapy, oral appliances, surgery, hypoglossal nerve stimulation, drug treatment, and combining 2 or more of the aforementioned treatments. Despite the many options available to treat OSA, none of them are as efficacious as CPAP. However, many of these treatments are tolerable, and adherence rates are higher than those of the CPAP, making them a more viable treatment option for long-term use. Conclusion Patients need to weigh the benefits and risks of available treatments for OSA. More large randomized controlled studies on treatments or combination of treatments for OSA are needed that measure parameters such as treatment adherence, apnea-hypopnea index, oxygen desaturation, subjective sleepiness, quality of life, and adverse events.

    PubMed

    Testa, Mark F; Smith, Brenda

    2009-01-01

    Evidence linking alcohol and other drug abuse with child maltreatment, particularly neglect, is strong. But does substance abuse cause maltreatment? According to Mark Testa and Brenda Smith, such co-occurring risk factors as parental depression, social isolation, homelessness, or domestic violence may be more directly responsible than substance abuse itself for maltreatment. Interventions to prevent substance abuse-related maltreatment, say the authors, must attend to the underlying direct causes of both. Research on whether prevention programs reduce drug abuse or help parents control substance use and improve their parenting has had mixed results, at best. The evidence raises questions generally about the effectiveness of substance abuse services in preventing child maltreatment. Such services, for example, raise only marginally the rates at which parents are reunified with children who have been placed in foster care. The primary reason for the mixed findings, say Testa and Smith, is that almost all the parents face not only substance abuse problems but the co-occurring issues as well. To prevent recurring maltreatment and promote reunification, programs must ensure client progress in all problem areas. At some point in the intervention process, say Testa and Smith, attention must turn to the child's permanency needs and well-being. The best evidence to date suggests that substance-abusing parents pose no greater risk to their children than do parents of other children taken into child protective custody. It may be sensible, say the authors, to set a six-month timetable for parents to engage in treatment and allow twelve to eighteen months for them to show sufficient progress in all identified problem areas. After that, permanency plans should be expedited to place the child with a relative caregiver or in an adoptive home. Investing in parental recovery from substance abuse and dependence, the authors conclude, should not substitute for a comprehensive approach

  18. Sewage sludge treatment system

    1976-01-01

    Raw sewage may be presently treated by mixing screened raw sewage with activated carbon. The mixture is then allowed to stand in a first tank for a period required to settle the suspended matter to the bottom of the tank as a sludge. Thereafter, the remaining liquid is again mixed with activated carbon and the mixture is transferred to a secondary settling tank, where it is permitted to stand for a period required for the remaining floating material to settle as sludge and for adsorption of sewage carbon as well as other impurities to take place. The sludge from the bottom of both tanks is removed and pyrolyzed to form activated carbon and ash, which is mixed with the incoming raw sewage and also mixed with the liquid being transferred from the primary to the secondary settling tank. It has been found that the output obtained by the pyrolysis process contains an excess amount of ash. Removal of this excess amount of ash usually also results in removing an excess amount of carbon thereby requiring adding carbon to maintain the treatment process. By separately pyrolyzing the respective sludges from the first and second settling tanks, and returning the separately obtained pyrolyzed material to the respective first and second tanks from which they came, it has been found that the adverse effects of the excessive ash buildup is minimized, the carbon yield is increased, and the sludge from the secondary tank can be pyrolyzed into activated carbon to be used as indicated many more times than was done before exhaustion occurs.

  19. Hypophosphatasia - pathophysiology and treatment

    PubMed Central

    Millán, José Luis; Plotkin, Horacio

    2013-01-01

    English Summary Hypophosphatasia (HPP) is the inborn-error-of-metabolism caused by loss-of-function mutation(s) in the gene that encodes the tissue-nonspecific isozyme of alkaline phosphatase (TNAP). The disease has been classified according to patient age when the first signs and symptoms manifest; i.e., perinatal, infantile, childhood, adult HPP. Other types include odonto HPP and perinatal benign. Babies with the perinatal/infantile forms of HPP often die with severe rickets and respiratory insufficiency and sometimes hypercalcemia and vitamin B6-responsive seizures. The primary biochemical defect in HPP is a deficiency of TNAP activity that leads to elevated circulating levels of substrates, in particular inorganic pyrophosphate (PPi), a potent calcification inhibitor. To-date, the management of HPP has been essentially symptomatic or orthopedic. However, enzyme replacement therapy with mineral-targeting TNAP (sALP-FcD10, also known as ENB-0040 or asfotase alfa) has shown promising results in a mouse model of HPP (Alpl−/− mice). Administration of mineral-targeting TNAP from birth increased survival and prevented the seizures, rickets, as well as all the tooth abnormalities, including dentin, acellular cementum, and enamel defects in this model of severe HPP. Clinical trials using mineral-targeting TNAP in children 3 years of age or younger with life-threatening HPP was associated with healing of the skeletal manifestations of HPP as well as improved respiratory and motor function. Improvement is still being observed in the patients receiving continued asfotase alfa therapy, with more than 3 years of treatment in some children. Enzyme replacement therapy with asfotase alfa has to-date been successful in patients with life-threatening HPP. PMID:25254037

  20. Treatment of nicotine dependence.

    PubMed

    Haxby, D G

    1995-02-01

    Drug and nondrug interventions used in treating nicotine dependence are reviewed. Tobacco use is the leading preventable cause of death in the United States. Risks of smoking-related disease and death decline sharply when smokers quit, but 26% of Americans continue to smoke. Most smokers find it extremely difficult to quit smoking because of their nicotine addiction. Nonpharmacologic interventions used to promote smoking cessation include behavioral therapy, setting a specific date for quitting, receiving advice to quit from a health care professional, follow-up visits to review progress, self-help approaches, group counseling, filtration devices, hypnosis, and acupuncture. The efficacy of these approaches ranges from substantial to almost nil. The only pharmacologic agent with FDA-approved labeling for use in smoking-cessation therapy is nicotine. When used in conjunction with appropriate nonpharmacologic interventions, nicotine-replacement therapy roughly doubles the rate of quitting obtained with placebo. Nicotine-replacement therapies consist of nicotine transdermal (patch) systems and nicotine chewing gum. The nicotine patch is the first-line replacement therapy because it is effective when accompanied by only minimal (as opposed to more intensive) nonpharmacologic interventions and because it is easier to use and comply with than gum. Clonidine, antidepressants, and buspirone require further study to determine what role, if any, they should play in the treatment of nicotine dependence. The stages of smoking cessation are precontemplation, contemplation, action, and maintenance; interventions are selected on the basis of the stage the smoker is in. Nicotine dependence is difficult to treat, but there are aids that boost a smoker's chances of quitting. Nicotine patches and chewing gum offer the most effective pharmacologic options, especially when combined with behavioral interventions and counseling.

  1. Internet-Delivered Psychological Treatments.

    PubMed

    Andersson, Gerhard

    2016-01-01

    During the past 15 years, much progress has been made in developing and testing Internet-delivered psychological treatments. In particular, therapist-guided Internet treatments have been found to be effective for a wide range of psychiatric and somatic conditions in well over 100 controlled trials. These treatments require (a) a secure web platform, (b) robust assessment procedures, (c) treatment contents that can be text based or offered in other formats, and (d) a therapist role that differs from that in face-to-face therapy. Studies suggest that guided Internet treatments can be as effective as face-to-face treatments, lead to sustained improvements, work in clinically representative conditions, and probably are cost-effective. Despite these research findings, Internet treatment is not yet disseminated in most places, and clinical psychologists should consider using modern information technology and evidence-based treatment programs as a complement to their other services, even though there will always be clients for whom face-to-face treatment is the best option.

    An account is given of the author's experience in the prosthetic treatment (removable appliances) of children. The authors consider that prosthetic treatment in the primary dentition can be both justified and indicated due to absence or loss of primary teeth. Treatment must take into consideration the growth of the jaws as well as eruption of the permanent teeth. Prosthetic treatment of the young permanent dentition and of the erupting secondary dentition may particularly be necessary, but one must absolutely take into consideration the continuous growth of the jaws. It is important that the dental surgeon have to activate the parents to participate in their child's oral home care.

    2004-06-01

    Status epilepticus (SE) is a life-threatening emergency that requires prompt treatment, including basic neuroresuscitation principles (the ABCs), antiepileptic drugs to stop the seizure, and identification of etiology. Symptomatic SE is more common in younger children. Treating the precipitating cause may prevent ongoing neurologic injury and facilitates seizure control. A systematic treatment regimen, planned in advance, is needed, including one for refractory status epilepticus (RSE). Here we emphasize definitions, clinical and electroencephalography stages, early treatment, special circumstances that may require immediate seizure control, and treatment of RSE. Because much clinical research in SE has been done in adults, we indicate the patient population studied.

    These guidelines provide a review of diagnosis, conservative and surgical treatment of haemorrhoids with primary focus on the surgical treatment. In symptomatic hemorrhoids it is recommended, that conservative treatment is used as basic treatment regardless of grading. The vast majority of grade II haemorrhoids are treated conservatively, but surgery may be considered in a few cases with pronounced symptoms. In these cases chirurgia minor, Doppler guided dearterilization procedures or stapled haemorrhoidopexy are recommended. In grade III and IV Doppler guided dearterilization procedures, stapled haemorrhoidopexy (Grade III) or conventional Milligan Morgan haemorrhoidectomy are recommended.

    An infrared pulsed laser was used to irradiate toenails with visible signs of bacterial/fungal infections. Seventeen subjects with both great toes involved were recruited in a podiatric private practice. Toes were randomized to receive either a single treatment or no treatment. The treatment was tolerated by all subjects without anesthesia and there were no occurrences of serious adverse effects. Eleven out of 14 (79%) treated toes improved. Improvement ranged from 2.1 to 6.1 mm over 90 days following a single treatment. There was a highly significant difference (p<0.001) between treated and untreated toes for nail bed clearing.

    Sexually transmitted diseases (STDs) are a major health problem for adolescents. Health care providers for adolescents play a critical role in preventing and treating STDs. In May 2002, the Centers for Disease Control and Prevention published the Sexually Transmitted Diseases Treatment Guidelines 2002. These evidence-based guidelines are based on a systematic literature review focusing on information that had become available since the 1998 Guidelines for Treatment of STDs. This article reviews the new STD treatment guidelines for gonorrhea, chlamydia, bacterial vaginosis, trichomonas, vulvovaginal candidiasis, pelvic inflammatory disease, genital warts, herpes simplex virus infection, syphilis, and scabies. Although these guidelines emphasize treatment, prevention strategies and diagnostic recommendations also are discussed.

  12. Identifying predictors of treatment response.

    PubMed

    Yoder, Paul; Compton, Don

    2004-01-01

    This article provides a rationale for considering predictors of growth in a treatment group as inadequate to identifying predictors of treatment response. When we interpret predictors of growth in a treatment group as synonymous with predictors of treatment response, we implicitly attribute all of the treated children's growth to the treatment, an untenable assumption under most conditions. We also contend that the use of standard scores in predictors of growth studies does not allow us to differentiate growth from treatment, from growth from other factors. We present two research methodologies that are appropriate methods of identifying predictors of treatment response: (a) single-subject experimental logic utilized to identify the specific participants in which treatment responses (not just growth) were found, combined with follow-up group comparison logic to identify the characteristics on which responders and nonresponders differ, and (b) statistical interactions among child/family/context characteristics and randomly assigned group membership. Principles for selecting potential predictors of treatment response are provided.

    Juvenile idiopathic arthritis (JIA) is the most common chronic rheumatic disease of the childhood with the highest risk of disability. Active disease persists in the adulthood in a significant portion of children with juvenile rheumatoid arthritis despite many developments in the diagnosis and treatment. Therefore, initiation of efficient treatment in the early period of the disease may provide faster control of the inflammation and prevention of long-term harms. In recent years, treatment options have also increased in children with juvenile idiopathic arthritis owing to biological medications. All biological medications used in children have been produced to target the etiopathogenesis leading to disease including anti-tumor necrosis factor, anti-interleukin 1 and anti-interleukin 6 drugs. In this review, scientific data about biological medications used in the treatment of rheumatoid arthritis and new treatment options will be discussed. PMID:26078691

    There is a growing body of evidence supporting the efficacy of various complementary and alternative medicine approaches in the management of headache disorders. These treatment modalities include nutraceutical, physical and behavioral therapies. Nutraceutical options comprise vitamins and supplements (magnesium, riboflavin, coenzyme Q(10), and alpha lipoic acid) and herbal preparations (feverfew, and butterbur). Although controversial, there are some reports demonstrating the benefit of recreational drugs such as marijuana, lysergic acid diethylamide and psilocybin in headache treatment. Behavioral treatments generally refer to cognitive behavioral therapy and biobehavioral training (biofeedback, relaxation training). Physical treatments in headache management are not as well defined but usually include acupuncture, oxygen therapy, transcutaneous electrical nerve stimulation, occlusal adjustment, cervical manipulation, physical therapy, massage, chiropractic therapy, and osteopathic manipulation. In this review, the available evidence for all these treatments will be discussed.

    Vitiligo is a common depigmenting acquired disorder affecting about 1-2% of the world population, regardless of race, ethnic background, or gender. It is characterized by the appearance of milky white maculae because of a loss of melanocytes. The disfiguring nature of vitiligo causes high psychosocial morbidity. This is especially pronounced in populations with darker skin tone, likely because of the marked contrast. A variety of nonsurgical treatment regimens are currently employed in vitiligo. We reviewed the latest studies carried out on different nonsurgical treatment modalities used in vitiligo. All nonsurgical treatment aid to repigment or depigmentation the skin, however, many of them require a prolonged treatment course and may yield minimal results as well as carry unwanted side effects. There is a need for further research into the causes of vitiligo and into discovering better treatments.

  18. Treatment of Frontotemporal Dementia

    Boxer, Adam L.

    2016-01-01

    Opinion statement Frontotemporal dementia (FTD) encompasses a spectrum of neurodegenerative diseases with heterogeneous clinical presentations and two predominant types of underlying neuropathology. FTD typically comprises three distinct clinical syndromes: behavioral variant frontotemporal dementia (bvFTD), semantic variant primary progressive aphasia (svPPA), and nonfluent variant primary progressive aphasia (nfvPPA). FTD also frequently overlaps both clinically and neuropathologically with three other neurodegenerative syndromes: corticobasal syndrome (CBS), progressive supranuclear palsy (PSP), and amyotrophic lateral sclerosis (ALS). Each syndrome can be associated with one or more underlying neuropathological diagnoses and are referred to as frontotemporal lobar degeneration (FTLD). Although the various FTD syndromes can substantially differ in terms of clinical symptoms and underlying pathology, the symptoms can be broadly categorized into behavioral, cognitive and motor domains. Currently there are no Food and Drug Administration (FDA) approved therapies for the above syndromes except riluzole for ALS. FTD treatment strategies generally rely on off-label use of medications for symptomatic management, and most therapies lack quality evidence from randomized, placebo-controlled clinical trials. For behavioral symptoms, selective serotonin reuptake inhibitors may be effective, while case reports hint at possible efficacy with antipsychotics or antiepileptics, but use of these latter agents is limited due to concerns regarding side effects. There are no effective therapies for cognitive complaints in FTD, which frequently involve executive function, memory, and language. Motor difficulties associated with FTD may present with parkinsonian symptoms or motor neuron disease, for which riluzole is indicated as therapy. Compared to idiopathic Parkinson’s disease, FTD-related atypical parkinsonism is generally not responsive to dopamine replacement therapies, but a

    Management of ankylosing spondylitis (AS) is challenged by the progressive nature of the disease. To date, no intervention is available that alters the underlying mechanism of inflammation in AS. Currently available conventional treatments are palliative at best, and often fail to control symptoms in the long term. Current drug treatment may perhaps induce a spurious state of "disease remission," which is merely a low level of disease activity. Non-steroidal anti-inflammatory drugs are first line treatment, but over time, the disease often becomes refractory to these agents. Disease modifying antirheumatic drugs are second line treatment and may offer some clinical benefit. However, conclusive evidence of the efficacy of these drugs from large placebo controlled trials is lacking. Additionally, these drugs can cause treatment-limiting adverse effects. Intra-articular corticosteroid injection guided by arthrography, computed tomography, or magnetic resonance imaging is an effective means of reducing inflammatory back pain, but controlled studies are lacking. A controlled study has confirmed moderate but significant efficacy of intravenous bisphosphonate (pamidronate) treatment in patients with AS; further evaluation of bisphosphonate treatment is warranted. Physical therapy and exercise are necessary adjuncts to pharmacotherapy; however, the paucity of controlled data makes it difficult to identify the best way to administer these interventions. Surgical intervention may be required to support severe structural damage. Thus, for patients with AS, the future of successful treatment lies in the development of pharmacological agents capable of both altering the disease course through intervention at sites of disease pathogenesis, and controlling symptoms.

    Background Recent investigations of language gains following treatment in bilingual individuals with chronic aphasia appear to confirm early reports that not only the treated language but also the non-treated language(s) benefit from treatment. The evidence, however, is still suggestive, and the variables that may mitigate generalisation across languages warrant further investigation. Aims We set out to examine cross-language generalisation of language treatment in a trilingual speaker with mild chronic aphasia. Methods & Procedures Language treatment was administered in English, the participant’s second language (L2). The first treatment block focused on morphosyntactic skills and the second on language production rate. Measurements were collected in the treated language (English, L2) as well as the two non-treated languages: Hebrew (the participant’s first language, L1) and French (the participant’s third language, L3). Outcomes & Results The participant showed improvement in his production of selected morphosyntactic elements, such as pronoun gender agreement, in the treated language (L2) as well as in the non-treated French (L3) following the treatment block that focused on morphosyntactic skills. Speech rate also improved in English (L2) and French (L3) following that treatment block. No changes were observed in Hebrew, the participant’s L1. Conclusions Selective cross-language generalisation of treatment benefit was found for morphosyntactic abilities from the participant’s second language to his third language. PMID:20221311

    Objective To explore reasons for clinical inertia in the management of persistent depression symptoms. Research Design We characterized patterns of treatment adjustment in primary care and their relation to the patient’s clinical condition by modeling transition to a given treatment “state” conditional upon the current state of treatment. We assessed associations of patient, clinician, and practice barriers with adjustment decisions. Subjects Survey data on patients in active care for major depression was collected at six-month intervals over a two-year period for the Quality Improvement for Depression (QID) studies. Measures Patient and clinician characteristics were collected at baseline. Depression severity and treatment were measured at each interval. Results Approximately one-third of the observation periods ending with less than a full response resulted in an adjustment recommendation. Clinicians often respond correctly to the combination of severe depression symptoms and less than maximal treatment by changing the treatment. Appropriate adjustment is less common, however, in management of less severely depressed patients who do not improve after starting treatment, particularly if their care already meets minimal treatment intensity guidelines. Conclusions Our findings suggest that quality improvement efforts should focus on promoting appropriate adjustments for patients with persistent depression symptoms, particularly those with less severe depression.
