    Full Text Available Paraquat (PQ is one of the most used herbicide globally; applied around trees in orchards and between crop rows to control broad-leaved and grassy weeds. Its oxidation results in the formation of superoxides which causes damage to cellular components. In this study, we determined the antioxidant effect vitamin C has on hemograms [hemoglobin (Hb, packed cell volume (PCV and total white blood cells count] of rats under these toxic insults. The animals grouped (A-D, comprising subgroups without vitamin C (A1, B1, C1, D1 and subgroups on vitamin C (A2, B2, C2, D2, received different sub-lethal doses of PQ administered intraperitoneally monthly to the animals over a period of three months. The Hb values obtained were significantly reduced (P≤0.05 at month 1 and (P≤0.001 at months 2 and 3. These changes became more pronounced with increased dose and time. Vitamin C treated subgroups (B2, C2 and D2 had better Hb values than those without it (B1, C1 and D1 but the values were still significantly low when compared to the control subgroups (A1 and A2. This same trend was observed in the PCV results obtained. The Control subgroups showed that vitamin C treated subgroup (A2 had a more improved hemogram values than subgroup on water only (A1, but they were all higher than that of the test subgroups. These PQ induced anaemia were ameliorated by the subsequent administration of vitamin C, and continuous treatment with vitamin C restored the health status of the animals so treated.

  3. ['Anatomia actuosa et apta'. The mechanist 'proto'-physiology of B.S. Albinus].

    Already during his tenure as professor of anatomy and surgery (1721-1746) and before he became a professor of physiology and medicine at the University of Leiden, Bernard Siegfried Albinus held private lecture courses on physiology. In these lectures he pleaded for a separation of physiology from theoretical medicine, which was still its customary place in the medical curriculum of the first half of the eighteenth century. According to Albinus, physiology was a science in its own right and should be solely based on the careful observation of forms and structures of the human body. From the 'fabrica', the function ('aptitudo') could be derived by careful reasoning. As shown by a set of lecture notes, which recently came to light, Albinus adhered, initially, to a strictly mechanistic explanatory model, which was almost completely based on the physiological concepts of Herman Boerhaave. However, in contrast to the latter, he even rejected the involvement of chemical processes in digestion. Although his lectures were highly acclaimed as demonstrations of minute anatomy, Albinus met with little or no direct response in regard to his concept of physiology.

    Full Text Available A necessidade de manejo adequado antes, durante e após a implementação de procedimentos em animais de laboratório é essencial para proporcionar bem-estar. Portanto, no presente trabalho, objetivou-se padronizar uma nova técnica de pinealectomia em ratas Wistar. Trinta fêmeas nulíparas aos 90 dias de idade foram submetidas à anestesia dissociativa. Após a tricotomia e a assepsia, realizou-se uma incisão na linha média dorsal da cabeça. Com um micromotor e uma broca de aço PM 03, realizou-se a craniotomia; a glândula pineal foi removida por intermédio de um fórceps cápsula arruga. Em seguida, o fragmento ósseo foi recolocado em seu lugar de origem, e a pele aproximada por pontos simples. Finalizado o procedimento cirúrgico, foi realizada antibioticoterapia e soroterapia parenteral. O acompanhamento diário dos animais não evidenciou nenhum comprometimento da ferida operatória com padrão de cicatrização por primeira intenção. Os animais apresentaram normalidade de atos fisiológicos, como alimentação, defecação e micção, assim como socialização com o grupo. Técnicas cirúrgicas vêm sendo realizadas com o desenvolvimento das pesquisas envolvendo a glândula pineal. A técnica ideal para pinealectomia consiste no pouco sangramento, na curta duração da cirurgia e na nitidez da glândula pineal, diminuindo a probabilidade de acidentes neurológicos. Considerando-se os resultados obtidos ao longo do desenvolvimento experimental e clínico, o aprimoramento da técnica cirúrgica utilizando a broca PM03 associada ao fórceps cápsula arruga foi exímio na pesquisa científica da pinealectomia de ratas Wistar em virtude da rapidez e praticidade alcançadas. Tem-se a perspectiva de que este artigo sirva de subsídio para o aprimoramento e a otimização do modelo experimental para posteriores estudos acerca de pesquisas com a glândula pineal e, assim, maior compreensão de sua complexidade sobre todos os sistemas do organismo.

    To compare the chronic effects of antiretrovirals (lamivudine, stavudine, delavirdine, nelfinavir, amprenavir and an association of lopinavir/ritonavir) on albino pregnant rats. Review. Department of Obstetrics, Federal University of São Paulo (UNIFESP), São Paulo, SP, Brazil. This was a comparative retrospective study formed by 18 groups of 10 pregnant rats each, which were nearly three months of age and weighed 200 g. All of them were medicated every day using a stomach probe, while the control group was given 1 mL of distilled water. The study groups received lamivudine (at 5, 15 and 45 mg/kg/day); stavudine (at 1, 3 and 9 mg/kg/day); nelfinavir (at 40, 120 and 360 mg/kg/day); amprenavir (at 46, 138 and 414 mg/kg/day); lopinavir/ritonavir (at 12.8/3.2, 38.4/9.6 and 115/28.8 mg/kg/day) and delavirdine (at 20 and 60 mg/kg/day). These represented 1, 3 and 9 times the human therapeutic dose, except for the last drug, for which the 9-times dose was not used. Maternal, litter and placental weights, implantation and reabsorption numbers, major external fetal malformations and fetal and maternal deaths were evaluated. The Kruskal-Wallis test was used to compare quantitative variables and the chi-square test was used to compare qualitative variables. At all three doses, stavudine increased the maternal weight (p=0.001), while lamivudine at 3- and 9-times doses reduced it (p0.05). Stavudine at all doses reduced the litter weights (p<0.001); however, lamivudine at the usual and 3-times doses, delavirdine at 3-times dose, and amprenavir at 3-times dose increased the litter weight (p<0.001). In the maternal compartment, we observed lethal toxicity in the pregnant rats that received amprenavir and ritonavir/lopinavir; and maternal weight change with lamivudine and stavudine. In the fetal compartment, adverse effects were observed in relation to litter weight from stavudine, lamivudine, delavirdine and amprenavir.

    Manganese (Mn) is one of the most abundant elements on earth, particularly in the soft bottom sediments of the oceans. As a micronutrient Mn is essential in the metabolic processes of organisms. However, at high concentrations the metal becomes a neurotoxin with well-documented effects. As a consequence of euthrophication, manganese is released from bottom sediments of coastal areas and the Norway lobsters, Nephrops norvegicus, can experience high levels of bioavailable Mn 2+ . Here, we present the first report showing that Mn also affects several fundamental processes in the mobilisation and activation of immunoactive haemocytes. When N. norvegicus was exposed to a realistic [Mn 2+ ] of 20 mg l -1 for 10 days 24.1 μg ml -1 was recorded in the haemolymph. At this concentration the total haemocyte count was reduced by ca. 60%. By using BrdU as a tracer for cell division, it was shown that the proliferation rate in the haematopoietic tissue did not increase, despite the haemocytepenia. A gene coding for a Runt-domain protein, known to be involved in maturation of immune active haemocytes in a variety of organisms, was identified also in haemocytes of N. norvegicus. The expression of this gene was >40% lower in the Mn-exposed lobsters as judged by using a cDNA probe and the in situ hybridisation technique. In response to non-self molecules, like lipopolysaccharide (LPS), the granular haemocytes of arthropods are known to degranulate and thereby release and activate the prophenoloxidase system, necessary for their immune defence. A degranulation assay, tested on isolated granular haemocytes, showed about 75% lower activity in the Mn-exposed lobsters than that for the unexposed. Furthermore, using an enzymatic assay, the activation per se of prophenoloxidase by LPS was found blocked in the Mn-exposed lobsters. Taken together, these results show that Mn exposure suppressed fundamental immune mechanisms of Norway lobsters. This identifies a potential harm that also

    Full Text Available Background Indonesia has the third largest tobacco consumption in the world after China and India. Nicotine as the main component of cigarette smoke has negative effects on the reproductive system, such as oocyte maturation, ovulation, and fertilization, and increasing the diploidy of oocytes. The goal of this research was to evaluate the effect of nicotine on oocyte maturation in Rattus norvegicus. Methods This was an experimental study with post test only control group design. The subjects were 40 rats selected homogenously and randomly. They were divided into a control group (receiving carboxy-methyl-cellulose sodium and 3 treatment groups (I-III receiving nicotine subcutaneously for 7 days at dosages of 21 mg/kgBW, 41 kg/kgBW and 84/kgBW, respectively. The observations comprised oocyte maturation stage, viz. germinal vesicle (GV, germinal vesicle breakdown (GVBD, metaphase I and metaphase II. Data were analyzed by one-way Anova with á=0.05, followed by Tukey’s HSD test. Results One-way Anova showed significant differences in oocyte maturation in all groups. Tukey’s HSD test showed that for GV, the differing groups were control and I, control and II, I and III. For GVBD, the differing groups were control and I, I and II, I and III. For metaphase I, the differing groups were control with I, II, and III, I and II, I and III. For metaphase II, the differing groups were control versus I, II, and III, I and II, I and III. Conclusion Low dose of nicotine is capable of affecting oocyte maturation in Rattus norvegicus.

    Once a nuisance by-catch, today the Norway lobster (Nephrops norvegicus) is a valuable UK fisheries commodity. Unfortunately, the species is very susceptible to quality deterioration post harvest as it quickly develops black spots and also spoils rapidly due to bacterial growth. Treatment with chemicals can stop the blackening and carefully monitored cold storage can result in a sensory shelf life of up to 6.5 days. The high susceptibility to spoilage greatly restricts the extent to which N. norvegicus can be distributed to retailers and displayed for sale. The application of modified atmosphere (MA) could be extremely beneficial, allowing the chilled product to stay fresh for a long period of time, thus ensuring higher sales. In the present study, we identified a gas mix for the MA packaging (MAP) of whole N. norvegicus lobster into 200 g retail packs. Our results show that a shelf life extension to 13 days can be achieved when retail packs are stored in MAP at 1 °C. Effectiveness of the MAP was evaluated by using a newly developed QIM for MA-packaged whole N. norvegicus and also by analyzing bacterial plate counts. Changes in the microflora and effects of different storage temperatures on the quality of the MA packs are also presented. The main specific spoilage organism (SSO) of modified atmosphere packaged Norway lobster is Photobacterium phosphoreum. © 2013.

    Full Text Available Introduction: Periodontitis is a condition of inflammation of the tooth supporting tissues generally caused by bacteria Phorphyromonas gingivalis (Pg. and is usually characterized by the occurrence of the alveolar bone resorption. Matrix metalloproteinase-2 (MMP-2 is an enzyme that plays an important role in inflammatory conditions. All-trans retinoic acid (ATRA is a metabolite of vitamin A which plays a role in healing the inflamed tissue and maintain the immune system. The purpose of this study was to determine the effect of ATRA on the expression of MMP-2 in mouse models Rattus norvegicus of periodontitis. Methods: Experimental laboratory by using post test only with control group design. This study used 25 male Wistar mice (Rattus norvegicus that divided into 5 groups. Group 1 (G1 is a group of healthy mice, group 2 (G2 is a group of sick mice as induced periodontitis without treatment, group 3 (G3 is a group of periodontitis mice treated with 5 mg/kg dose of ATRA, group 4 (G4 is a group of periodontitis mice treated with 10 mg/kg dose of ATRA, group 5 (G5 is a group of periodontitis mice treated with 20 mg/kg dose of ATRA. Periodontitis induction was induced by Pg. bacteria every 3 days for 28 days and followed by administration of ATRA for 7 days. Expression of MMP-2 from gingival tissues and periodontal ligament was obtained by immunohistochemical methods. Results were analyzed using the Shapiro-Wilk Test and Mann-Whitney Test. Results: The results showed there were significant differences in the positive area of MMP-2 and MMP-2 color intensity (p < 0.05 between groups. Conclusion: ATRA dose of 20 mg/kg is the most effective dose in inhibiting the expression of MMP-2 in mice models of periodontitis when compared with the dose on other groups.

    Rattus norvegicus (Mammalia: Rodentia) is a widespread and synanthropic rodent, broadly used in medical experiments. It can also be used for feeding captive animals in zoos. Parasitological surveys are important to guarantee the health of both the animals and the staff responsible for their management. The aim of this study was to identify intestinal parasites of Rattus norvegicus offered as food to captive animals from São Paulo Zoo, and demonstrate the importance of sanitary hurdling, disease control and biosecurity. The identified protozoan parasites were Eimeria sp., Entamoeba sp., Spironucleus sp., Giardia sp., Tritrichomonas sp., Chilomastix sp., unidentified cysts and non-sporulated coccidians oocysts (Isospora/Eimeria). The following helminths were found: Syphacia muris, Rodentolepis nana and Aspiculuris tetraptera.

    Transmission experiments were performed to elucidate the life cycle of Sarcocystis zuoi found in Norway rats ( Rattus norvegicus ) in China. Two king rat snakes ( Elaphe carinata ) fed sarcocysts from the muscles of 4 naturally infected Norway rats shed sporocysts measuring 10.8 ± 0.7 × 8.0 ± 0.7 µm, with a prepatent period of 8-9 days. Sporocysts from the intestine of 2 experimentally infected king rat snakes were given to the laboratory Sprague-Dawley (SD) rats ( R. norvegicus ) and Kunming (KM) mice ( Mus musculus ). Microscopic sarcocysts developed in the skeletal muscles of SD rats. No sarcocysts were observed in KM mice. Characters of ultrastructure and molecule of sarcocysts from SD rats were confirmed as S. zuoi . Our results indicate that king rat snake is the definitive host of S. zuoi .

    Successful commercial aquaculture of crustacean species is dependent on satisfying their nutritional requirements and on producing rapidly growing and healthy animals. The results of the present study provide valuable information for feeding habits and growth of Nephrops norvegicus L., 1758) under laboratory conditions. The aim of the present study was to examine food consumption, growth and physiology of the Norway lobster N. norvegicus under laboratory conditions. N. norvegicus (15 g wet weight) were distributed into 1001 tanks consisting of five numbered compartments each. They were fed the experimental diets (frozen mussels and pellets) for a period of 6 months. A group of starved Nephrops was stocked and fasted for 8 months. Although Nephrops grew well when fed the frozen mussels diet, feeding on a dry pellet feed was unsatisfactory. The starvation group, despite the fact that showed the highest mortality (50%), exhibited a remarkable tolerance to the lack of food supply. The study offers further insight by correlating the amino acid profiles of Nephrops tail muscle with the two diets. The deviations from the mussel's diet for asparagine, alanine and glutamic acid suggest a deficiency of these amino acids in this diet. The results of the present study showed that the concentrations of free amino acids are lower in relative amount than those of protein-bound amino acids, except for arginine, proline and glycine. The present study contributes to the improvement of our knowledge on nutritional requirements of the above species. © 2010 ISZS, Blackwell Publishing and IOZ/CAS.

    The expression levels of cIAP genes and cMET were determined in liver tissues with and without neoplasm of the organism Rattus norvegicus, for prevention, diagnosis and treatment of hepatocellular carcinoma. The technique of reaction Polymerase Chain in real time (qPCR), is used to obtain the expression, of both genes cIAP and cMET, and this has decreased in neoplastic samples compared to samples not affected. The expression of these genes has been analyzed in samples with neoplastic formations, but treated with an anti-tumor agent. The expression has presented an increase of the cMET gene, unlike the cIAP gene, which has decreased its expression. Perform statistical analysis has been impossible because the number of samples used has been reduced. The results obtained differ with those expected theoretically. (author) [es

    1. A major locus with two alleles is responsible for large differences in erythrocyte 2,3-diphosphoglycerate (DPG) levels in Rattus norvegicus. Blood from homozygous High-DPG, homozygous Low-DPG and heterozygous animals was used to measure blood indices and red cell enzyme activities. 2. Significant differences between groups were found in DPG levels, white blood cell counts and hemoglobin levels. 3. The results suggest that none of the red cell enzymes assayed is structurally or quantitatively different in the three groups.

    Certain dietary constituents can induce toxicity and play a critical role in the development of several hepatic disorders. Tartrazine, metanil yellow and sunset yellow are widely used azo dyes in food products, so the present study is aimed to investigate the food color induced hepatotoxicity in Swiss albino rats. Swiss albino rats were divided into four groups, each group having six animals. Group I served as control, Group II, Group III and Group IV were administered with 25, 50 and 75 mg/kg body weight blend of sunset yellow, metanil yellow and tartrazine for 30 days. Hepatotoxicity in rats treated with a blend of these food colors was studied by assessing parameters such as serum total protein, serum albumin, serum alkaline phosphatase (ALP) as well as hepatic malondialdehyde (MDA). The activity of superoxide dismutase (SOD), reduced glutathione (GSH) and catalase (CAT) were assessed. Significantly increased concentrations of serum total protein, serum albumin, serum ALP and hepatic MDA and significantly lowered levels of SOD, reduced GSH and CAT in the liver tissue of treated animals were observed when compared with control animals. The alteration in the liver includes necrosis of hepatocytes, infiltration and vacuolation. The result indicates that consumption of food color in diet induces liver tissue damage. The used doses of food color were mostly attributable to hepatocellular damage and drastic alteration in antioxidant defense system.

  18. Food Neophobia in Wild Rats (Rattus norvegicus Inhabiting a Changeable Environment-A Field Study.

    Directory of Open Access Journals (Sweden)

    Klaudia Modlinska

    Full Text Available Food neophobia is a reaction to novel food observed in many animal species, particularly omnivores, including Rattus norvegicus. A neophobic reaction is typically characterised by avoidance of novel food and the necessity to assess both its potential value and toxicity by the animal. It has been hypothesised that this reaction is not observed in rats inhabiting a changeable environment with a high level of variability with regard to food and food sources. This study was conducted in such changeable conditions and it aims to demonstrate the behaviour of wild rats R. norvegicus in their natural habitat. The rats were studied in a farm setting, and the experimental arena was demarcated by a specially constructed pen which was freely accessible to the rats. At regular intervals, the rats were given new flavour- and smell-altered foods, while their behaviour was video-recorded. The results obtained in the study seem to confirm the hypothesis that rats inhabiting a highly changeable environment do not exhibit food neophobia. The observed reaction to novel food may be connected with a reaction to a novel object to a larger extent than to food neophobia. The value of the results obtained lies primarily in the fact that the study was conducted in the animals' natural habitat, and that it investigated their spontaneous behaviours.

The purpose of this study was to estimate the prevalence of Giardia spp. in brown rats (Rattus norvegicus in Grenada. Materials and Methods: Intestinal contents from 99 and serum samples from 169 brown rats (R. norvegicus from Grenada were collected. These samples were examined for the Giardia coproantigens using Cryptosporidium/Giardia Quik Chek assay (Tech lab® Inc., USA, and the serum was screened through an enzyme-linked immunosorbent assay (ELISA test kit for Giardia antibody (anti-GD ELISA kit (MyBioSource, San Diego, CA, USA. Results: Giardia coproantigens were positive in 17.17% (95% confidence interval [CI]; 10.33-26.06% rats, whereas 55% (95% CI: 47.20-62.68 were positive with serum antibodies (anti-GD to Giardia. Conclusion: The prevalence of Giardia spp. in brown rats in Grenada was moderate based on the presence of coproantigens in the intestinal contents and antibody in serum. The findings of Giardia infections and prevalence in brown rats will help veterinarians and physicians to better plan diagnostic and preventative strategies. This is the first report of prevalence of Giardia in brown rats in Grenada.

    Throughout the developing world, urban centers with sprawling slum settlements are rapidly expanding and invading previously forested ecosystems. Slum communities are characterized by untended refuse, open sewers, and overgrown vegetation, which promote rodent infestation. Norway rats (Rattus norvegicus), are reservoirs for epidemic transmission of many zoonotic pathogens of public health importance. Understanding the population ecology of R. norvegicus is essential to formulate effective rodent control strategies, as this knowledge aids estimation of the temporal stability and spatial connectivity of populations. We screened for genetic variation, characterized the population genetic structure, and evaluated the extent and patterns of gene flow in the urban landscape using 17 microsatellite loci in 146 rats from 9 sites in the city of Salvador, Brazil. These sites were divided between three neighborhoods within the city spaced an average of 2.7 km apart. Surprisingly, we detected very little relatedness among animals trapped at the same site and found high levels of genetic diversity, as well as structuring across small geographic distances. Most FST comparisons among sites were statistically significant, including sites Salvador, linked to the heterogeneous urban landscape. Future rodent control measures need to take into account the spatial and temporal linkage of rat populations in Salvador, as revealed by genetic data, to develop informed eradication strategies.

    Full Text Available In the present study we surveyed the fauna of phlebotomine sand flies and small mammals in peridomestic areas from a Brazilian municipality where the American cutaneous leishmaniasis (ACL is endemic. A total of 608 female phlebotomine sand flies were captured during nine months in 2009 and 2010. Seven different species were represented with 60% of them being Lutzomyia intermedia and Lu. whitmani, both incriminated vectors of ACL. Lu. longipalpis, a proven vector of visceral leishmaniasis (VL was also captured at high proportion (12.8%. Genomic DNA analysis of 136 species-specific pools of female sand flies followed by molecular genotyping showed the presence of Leishmania infantum DNA in two pools of Lu. longipalpis. The same Leishmania species was found in one blood sample from Rattus norvegicus among 119 blood and tissue samples analysed. This is the first report of Le. infantum in R. norvegicus in the Americas and suggests a possible role for this rodent species in the zoonotic cycle of VL. Our study coincided with the reemergence of VL in Governador Valadares.

    Loo, Lars-Ove; Pihl Baden, Susanne; Ulmestrand, Mats

    Suspension feeding in adults of the Norway lobster Nephrops norvegicus (40-74 g) and the European lobster Homarus gammarus (280-350 g) was tested in experiments offering planktonic food items of different sizes from 200 to 600 μm and measuring the clearing capacity. Both lobster species were found to effectively clear water of food particles comprising nauplii of the brine shrimp Artemia salina of about 600 μm in size. These were reduced to 50% of the initial concentration within 5 h and to 90% within 12 h. When N. norvegicus was offered food particles averaging 200 μm, a significant reduction in average size occurred, indicating that the minimum retention size is around 200 μm. Fluorescently dyed Artemia salina were recovered in the stomach and intestine of lobsters proving that the filtered particles are passed to the digestive tract. Results from other experiments, using the blood pigment (haemocyanin) concentration as an index of nutritional state, indicated that the lobsters can get some nutritional advantage from suspension feeding. Suspension feeding in larger decapods has not been described previously, so the significance of this finding is discussed with respect to changes in behavioural and ecological role.

    This study investigated associations between Trypanosoma lewisi; Xenopsylla cheopis, a common cyclical vector of T. lewisi; Polyplax spinulosa, a reported mechanical vector; and Laelaps ecidnina and L. lamborni, two rodent mites of Rattus norvegicus in Durban. Three hundred and seventy nine R. norvegicus were live-trapped at 48 sites in 4 locality types of Durban during a one year period. Rats were euthanized, cardiac blood was taken to check for hemoparasites and ectoparasites were removed for identification. Parasite species richness was higher in pups (2.11) and juveniles (1.02) than adults (0.87). Most rats in the study harbored 1 or 2 of the 5 parasites examined. Rats with trypanosomes and fleas were more prevalent in the city center and harbor, and juveniles were most affected. Rats with lice were more prevalent in informal settlements and urban/peri-urban areas and pups had the highest infestations. There was a significant positive association between rats with fleas and trypanosomes and a negative association between rats with lice and trypanosomes. Location and rat age were significant predictors of T. lewisi, X. cheopis and P. spinulosa. Mites showed no strong associations with trypanosomes. Ectoparasite associations are possibly habitat and life-cycle related. We conclude that Durban's city center, which offers rats harborage, an unsanitary environment and availability of food, is a high transmission area for fleas and trypanosomes, and consequently, a potential public health risk.

    The selectivity for Nephrops (Nephrops norvegicus) in trawl codends generally is poor and the lack of steepness of the selection curve results in high discard rates and/or loss of legal-sized catch. This poor codend selectivity often is attributed to the irregular shape of Nephrops, which to some...

    Levanox, a hepato protective drug, and garlic powder have been considered as safe anti-oxidant agents. The present investigation refers to biochemical and molecular studies to evaluate the protective role of levanox and/or garlic powder toward CCl4-induced toxicity in adult male albino rats. CCl4 intoxication was attempted using a dose of 0.03 ml/kg of rat body weight.Pre-treatment with levanox (one capsule/ kg of rat body weight, each capsule contains 100 mg catechu, 7.5 mg dandelion, 75 mg termiric 2 % curcumin , 17.5 mg silymarin, 100 mg lecithin) was more effective than garlic powder (100mg/kg of rat body weight) in reducing CCl4-induced hepatotoxicity as revealed by its higher potency in reducing elevation of aspartate (AST) and alanine (ALT) aminotransferases in serum. Serum of control rats and those treated with levanox or garlic or CCl4 produced 13 types of proteins, differing in the molecular weight (MW) and densities, while those of levanox + garlic or garlic +CCl4 produced 14 bands differing in the MW and densities. The similarity index at the epigenetic level was also studied using the primers under study. The control sample produced one amplified DNA fragment with Rf of 0.73 and a molecular size (MS) of 67 base pair (bp) .

    Laboratory experiments were carried out to study bioaccumulation and determine a concentration factor (CF) for technetium ( 95m Tc) in the homarid crustacean Nephrops norvegicus L. The steady state CF for accumulation from seawater was estimated to be about 2000 and the biological half-time was about 50 days. The highest tissue Tc concentrations were found in the green gland and the digestive gland. Depuration following accumulation from water was slow with a half-time of about 165 days. Tc accumulation from labelled food followed a biphasic model with one compartment containing about 94 percent of the ingested activity and with a half-time of about 1 day and the second compartment containing about 6 percent of the ingested activity with a half-time of about 56 days. Most retained activity was found in the digestive gland

    A substantial improvement in the bycatch selectivity of Norway lobster Nephrops norvegicus trawls is required, particularly with respect to cod Gadus morhua , whose stocks are at low levels in several areas. Conventional escape windows are not adequate to properly release cod and other bycatch...... species caught in the trawls. To address this issue, we developed a novel sorting box concept consisting of a four-panel section with a window on the top in order to improve the escape of cod and other bycatch species through an escape window while retaining the target catch of Norway lobster. The concept....... The reduction in bycatch decreased with decreasing mesh size and increasing height of the sorting box. Escape of Norway lobster through the escape window was limited. A modified version of the sorting box concept was implemented in the Kattegat fishery from 2009 onwards...

To improve retention of these species, we developed three new grids using made by polyurethane to make them flexible: One grid had horizontal bars, one had vertical bars....... More flatfish passed the grid with horizontal bars compared to that with vertical bars, but the retention rate was still low. Use of the guiding funnel increased the contact with the grid considerably for both target and unwanted species. In all three grid designs, there were losses of Norway lobster...

    Full Text Available The effect of fluoride on the calcium level in serum was analyzed in the laboratory rat Rattus norvegicus. The control group consisted of 10, and the experimental group of 15 animals. In the experimental group, fluoride at a concentration of 3 mg/100 g body weight of rats was intramuscularly injected into the musculus gluteus maximus. The concentration of calcium was measured by the CPC method. The average serum calcium concentration was 2.46 mmol/l, with female rats having higher values of serum calcium than male rats. Fluoride caused the reduction of calcium concentration in serum (p<0.05; the reduction was significantly expressed in female rats (p<0.000.

    Full Text Available Background: Traditional wound treatment using herbal medicine is thought to maintain the health of families and society in general economically, effectively, and efficiently without inducing side effects. One genus of plant that can be used as a traditional medicine is the Mauli banana, indigenous to South Borneo. Mauli banana stem contains bioactive compounds, most of which are tannins along with ascorbic acid, saponin, β-carotene, flavonoids, lycopene, alkaloids, and flavonoids. Tanin has antibacterial and antioxidant effects at low concentrations, as wells as antifungal ones at high concentrations. Purpose: This study aimed to analyze the effects of Mauli banana stem extract at concentrations of 25%, 37.5%, and 50% on the quality of incised wound healing in male Rattus norvegicus rats by assessing FGF-2 expression and fibroblast concentration on days 3 and 7. Methods: This research represented an experimental laboratory-based investigation involving 32 rats of the Rattus norvegicus strain aged 2-2.5 months old. Sampling was performed using a simple random sampling technique since the research population was considered homogeneous and divided into 8 treatment groups (C3, M3-25, M3-37.5, M3-50, C7, M7-25, M7-37.5, M7-50. The rats in each group were anesthetized before their back was incised with length and width of 15x15mm with a depth of 2mm. Gel hydroxy propyl cellulose medium (HPMC was applied to the incised wound of each rat in the control group, while stem Mauli banana extract was applied to that of each rat in the treatment groups three times a day at an interval of 6-8 hours. On day 3, four rats from each group were sacrificed, while, in the remaining groups, the same procedure was performed until day 7, at which point they (8 groups were sacrificed for HE examination in order to assess the amount of fibroblast and for IHC examination to examine FGF-2 expression. Data regarding FGF-2 expression and the amount of fibroblast were analysed

    Full Text Available Abstract Some of the most relevant aspects of the feeding behaviour of the rat (Rattus norvegicus, Berkenhout, 1769 were examined with particular interest in the data collected on wild rats and in natural environments. The rat is considered as an omnivore and generalist species, but both in the wild and in the laboratory marked individual differences were recorded in food preferences and diet spectrum, which probably allow the natural populations to exploit a great number of habitat resources. A number of causes were identified as responsible of these differences: early pup differentiation; mother's and conspecifics' influences, etc. The importance of animal food in the rat diet is also variable. The diet of non-commensal rat colonies was examined with special reference to the predatory behaviour, which is a common habit in natural populations; furthermore the insorgence of "local traditions" such as the Mollusc predation was considered. The hypothesis of social transmission of this feeding habit, widespread in the Po river Basin and Delta, was discussed and confirmed. The hoarding behaviour, well studied under laboratory conditions, was rarely recorded in the wild. It is supposed to be a useful mechanism that the rat uses to cope with particular conditions (e.g. surplus of food, lactating females but this species cannot be defined as a "natural hoarder". The degree of neophobia is variable in populations that interact with man and it is practically absent in non-commensal populations. This confirms that it is a defensive strategy resulting from the commensal habit of the rat and not a fixed behavioural characteristic of this rodent species. The stealing of food between animals, kleptoparasitism, was frequently observed in confined rat groups in laboratory but rarely described in the wild. It is compared with the "worker-parasite" relationship supposed to be a kind of division of labour. The most important components of

    Full Text Available In 1768 J.E. Gunnerus first described the species Hydroides norvegicus (Polychaeta, Serpulidae, the type of the genus Hydroides which today includes close to 90 species worldwide and is the largest serpulid genus. This description has therefore great value as a type description, but as it is written in an old-fashioned Danish/Norwegian language with a font which is hard to interpret, the description is rather inaccessible to most polychaetologists. This paper presents a translation of Gunnerus’ description of H. norvegicus and a brief review of the present day status of the species. Comments on Gunnerus’ description of Serpula triqvetra are also included, as well as references to his correspondence with Swedish naturalist Carolus Linnæus regarding the species in question.

    Virgin coconut oil (VCO) and olive oil are edible oil containing an antioxidant that can prevent free radicals in Rattus rattus norvegicus hypoglycemic due to the damage of pancreatic beta cell after alloxan injection. Virgin coconut oil and olive oil are fatty acids when being consumed will affect lipid metabolism particularly HDL, LDL and cholesterol in serum. This research aims to determine the effect of VCO and Olive oil on cholesterol levels in hyperglycemic rats. Research materials were twenty male Rattus rattus norvegicus. Randomized Factorial Design was used in four treatment groups including P1(control), P2 (mice injected with alloxan), P3 (mice injected with alloxan plus 0.1 ml/BW of each VCO and vitamin E) and P4 (mice injected with alloxan plus 0.1 ml/BW of each olive oil and vitamin E. Each treatment was replicated 5 times. Feed and water were provided adlibitum for four weeks. The result showed that there was no significant difference in the level of HDL serum across the treatments, but P4 had a significantly higher LDL than the other treatments. Moreover, total cholesterol was significantly increased in P4 compared to the other groups. It can be concluded that olive oil could increase the level of cholesterol and LDL in serum, while VCO did not increase the level of cholesterol and LDL so VCO more potential to maintain cholesterol in hyperglycemic Rattus rattus norvegicus.

    The Norway or brown rat (Rattus norvegicus) is among the most ubiquitous of rodents. However, the lack of studies describing Norway rat populations from tropical areas have limited our understanding regarding their demography and seasonal dynamics. In this study, we describe seasonal pattern in the abundance, reproductive parameters, and morphometrics of Norway rat populations in Salvador, Brazil. Rodents were trapped over four seasonal trapping periods (2013-2014) from three valleys. A total of 802 Norway rats were trapped over the course of the study over 7653 trap-nights. Norway rat abundance was high, but there was no significant differences between seasons. The reproductive parameters (e.g. frequency of pregnant and lactating females) did not show statistical differences between seasons. Female rats collected in the rainy season were heavier and older than females from the dry season. Salvador rats had a high incidence of pregnancy and birth rate (estimated birth rate of 79 young per year) compared to previous studies. The information generated is critical for the understanding of the ecology of Norway rat, the main reservoir of Leptospira in Salvador. However, future studies examining the effect of rodent control programs aimed at reducing populations, and determining rates of recovery, will further clarify our understanding of population dynamics.

    Graphical abstract: - Highlights: • The crystal structure of GKAP homology domain 1 (GH1) was determined. • GKAP GH1 is a three-helix bundle connected by short flexible loops. • The predicted helix α4 associates weakly with the helix α3, suggesting dynamic nature of the GH1 domain. - Abstract: Guanylate-kinase-associated protein (GKAP) is a scaffolding protein that links NMDA receptor-PSD-95 to Shank–Homer complexes by protein–protein interactions at the synaptic junction. GKAP family proteins are characterized by the presence of a C-terminal conserved GKAP homology domain 1 (GH1) of unknown structure and function. In this study, crystal structure of the GH1 domain of GKAP from Rattus norvegicus was determined in fusion with an N-terminal maltose-binding protein at 2.0 Å resolution. The structure of GKAP GH1 displays a three-helix bundle connected by short flexible loops. The predicted helix α4 which was not visible in the crystal structure associates weakly with the helix α3 suggesting dynamic nature of the GH1 domain. The strict conservation of GH1 domain across GKAP family members and the lack of a catalytic active site required for enzyme activity imply that the GH1 domain might serve as a protein–protein interaction module for the synaptic protein clustering

    Full Text Available Uric acid is the end product of purine degradation. When uric acid levels exceed normal limits, it will build up and cause hyperuricemia. Allopurinol is one of the most effective and common medicine for hyperuricemia, but it brings serious side effects, therefore it is needed alternative therapy for hyperuricemia. One plant that may be expected to low uric acid levels is green tea (Camellia sinensis L., that contains many antioxidants polyphenols, especially flavonoids. Flavonoid has strong antioxidant properties, act as free radical and metal scavengers, and also xanthine oxidase (XOD inhibitors. This study investigates the potential of green tea using various doses of 150 mg/kg, 300 mg/kg, and 600 mg/kg of body weight in 24 white male rats (Rattus norvegicus Wistar strain that has been received high purine diet in 60 consecutive days. This study used DHBSA methods to measure uric acid levels in blood serum and urine that excreted 8 hours before surgery. Green tea extract that contains polyphenol can inhibit XOD activities, therefore, it leads to decrease uric acid level in blood and increase the excretion through urine by modulating urate gene transporter. A therapy with 600 mg/kg body weight of GTE is the most effective dose to decrease uric acid levels in serum and to increase excretion of exceeding uric acid significantly (p < 0.01, from One Way ANOVA and Tukey analysis.

  6. Low prevalence of human enteropathogenic Yersinia spp. in brown rats (Rattus norvegicus in Flanders.

    Lieze Oscar Rouffaer

    Full Text Available Brown rats (Rattus norvegicus have been identified as potential carriers of Yersinia enterocolitica and Y. pseudotuberculosis, the etiological agents of yersiniosis, the third most reported bacterial zoonosis in Europe. Enteropathogenic Yersinia spp. are most often isolated from rats during yersiniosis cases in animals and humans, and from rats inhabiting farms and slaughterhouses. Information is however lacking regarding the extent to which rats act as carriers of these Yersinia spp.. In 2013, 1088 brown rats across Flanders, Belgium, were tested for the presence of Yersinia species by isolation method. Identification was performed using MALDI-TOF MS, PCR on chromosomal- and plasmid-borne virulence genes, biotyping and serotyping. Yersinia spp. were isolated from 38.4% of the rats. Of these, 53.4% were designated Y. enterocolitica, 0.7% Y. pseudotuberculosis and 49.0% other Yersinia species. Two Y. enterocolitica possessing the virF-, ail- and ystA-gene were isolated. Additionally, the ystB-gene was identified in 94.1% of the other Y. enterocolitica isolates, suggestive for biotype 1A. Three of these latter isolates simultaneously possessed the ail-virulence gene. Significantly more Y. enterocolitica were isolated during winter and spring compared to summer. Based on our findings we can conclude that brown rats are frequent carriers for various Yersinia spp., including Y. pseudotuberculosis and (human pathogenic Y. enterocolitica which are more often isolated during winter and spring.

    2009-03-01

    Data on biological rhythms of the Norway lobster Nephrops norvegicus (L.) are compared with new findings on inertial currents, a non-photic geophysical hydrodynamic fluctuation. Laboratory experiments on animal endogenous cardiac activity and locomotor rhythms using individuals from the middle slope (400-600 m depth) of the Mediterranean Sea revealed a consistent proportion of ultradian 18-h animals (20.6% and 12.0% of the studied cases for cardiac and locomotor tests, respectively). This characteristic, not reported in similar experiments with individuals from shallower depths (20-200 m) in the Atlantic Ocean, was initially considered meaningless from an ecological point of view. However, a close comparison with in situ oceanographic measurements over 1 year revealed a clear relationship between inertial current fluctuations and the observed 18-h behavioural and physiological rhythms. We propose a novel scenario involving potential non-photic (i.e. hydrodynamic) modulation of Nephrops biorhythms, and suggest that this may provide a paradigm for other benthic species in deep-water areas.

    Full Text Available The Norway lobster, Nephrops norvegicus, can be captured by haul nets only during the emergence from its burrow. In the last few decades, an extensive field research revealed distinct diel (24-h–based catchability patterns at different depths. Laboratory experiments suggested that burrow emergence (used as a proxy of catchability is endogenously controlled via a circadian system. Results were usually presented in terms of mean effects without a quantification of inter-individual variability and arrhythmia. Here, we studied the burrow emergence of 52 adult Nephrops by an infrared actograph endowed with an artificial burrow. Animals were exposed to 12-12 h light-darkness cycle, simulating photic condition of the lower shelf. Forty-five animals showed rhythmic emergence (87%, while seven were arrhythmic (13%. Rhythmic animals were clustered according to their timing of emergence: 54% at dusk and 4% at dawn. Moreover, other animals showed fully diurnal or nocturnal emergence (10% and 19%, respectively. The comparison of our results with those derived from temporally scheduled trawling indicates that bimodal catch patterns observed in shelf populations are poorly observed during individual experiments in the laboratory, where the same light conditions are simulated. Nephrops burrow emergence seems to be the result of a mixed endogenous-exogenous control, while arrhythmia could also be present in the wild.

  10. Effects of drilling cuttings on the behavior of the Norway lobster Nephrops norvegicus

    Small quantities of drilling cuttings (100 g/250 cm/sup 2/) were found to affect both the survival and general behavior of Nephrops norvegicus held in experimental aquaria. In one experiment volatile hydrocarbons released from the cuttings caused a significant decrease in the heat of the exopodite on the third maxilliped. Flicking rates of the antennule and the time taken to identify and capture food introduced into the tanks were unaffected by exposure to cuttings. When the water flow through the tanks was interrupted for 12 h, 58% of animals died after exposure to the highest concentration of cuttings but those at the lower concentrations survived. After the water flow was restored the remaining survivors showed disorientated behavior and uncoordinated movements which lasted for about 36 h. In this condition animals will be more vulnerable to predators. This unnatural behavior may have serious implications for natural populations exposed to cuttings discharge in the close vicinity of offshore drilling platforms. 11 references, 3 tables.

    Graphical abstract: - Highlights: • The crystal structure of GKAP homology domain 1 (GH1) was determined. • GKAP GH1 is a three-helix bundle connected by short flexible loops. • The predicted helix α4 associates weakly with the helix α3, suggesting dynamic nature of the GH1 domain. - Abstract: Guanylate-kinase-associated protein (GKAP) is a scaffolding protein that links NMDA receptor-PSD-95 to Shank–Homer complexes by protein–protein interactions at the synaptic junction. GKAP family proteins are characterized by the presence of a C-terminal conserved GKAP homology domain 1 (GH1) of unknown structure and function. In this study, crystal structure of the GH1 domain of GKAP from Rattus norvegicus was determined in fusion with an N-terminal maltose-binding protein at 2.0 Å resolution. The structure of GKAP GH1 displays a three-helix bundle connected by short flexible loops. The predicted helix α4 which was not visible in the crystal structure associates weakly with the helix α3 suggesting dynamic nature of the GH1 domain. The strict conservation of GH1 domain across GKAP family members and the lack of a catalytic active site required for enzyme activity imply that the GH1 domain might serve as a protein–protein interaction module for the synaptic protein clustering.

  12. Temporal modification in cardiac rhythmicity of Nephrops norvegicus (Crustacea: Decapoda in relation to trawl capture stress

    2005-09-01

    Full Text Available The effects of trawling on cardiac rhythmicity of Nephrops norvegicus (L. are still mostly unknown. Ultradian rhythms reported in previous studies may result from trawling capture stress, thus disappearing following acclimatisation to laboratory conditions. To test this hypothesis, 34 time series of cardiac activity data recorded in constant darkness were studied by Fourier analysis. Spectral decomposition of time series was obtained by defining the fundamental or circadian harmonic (CH in 24-h together with 9 submultiples of this period. The power content (PC of each harmonic was estimated in data segments of 24-h duration (days, giving graphic matrices of PC values over consecutive days. Values of PC for 9 submultiples were summed and studied in a block named ultradian band (UB. The modification in the PC of the CH and of the UB was evaluated during laboratory acclimatisation. A significant increase in the PC of the circadian harmonic component (CH over consecutive days of testing was observed. These findings suggest that, rather than being a product of dim light environmental fluctuations experienced by the animals from the deep waters of the continental slope, ultradian periodicity could well be caused by the stress of capture.

  15. Modeling the distribution of Norway rats (Rattus norvegicus on offshore islands in the Falkland Islands

    Full Text Available Non-native rats (Rattus spp. threaten native island species worldwide. Efforts to eradicate them from islands have increased in frequency and become more ambitious in recent years. However, the long-term success of some eradication efforts has been compromised by the ability of rats, particularly Norway rats (Rattus norvegicus which are good swimmers, to recolonize islands following eradications. In the Falkland Islands, an archipelago in the South Atlantic Ocean, the distance of 250 m between islands (once suggested as the minimum separation distance for an effective barrier to recolonization has shown to be insufficient. Norway rats are present on about half of the 503 islands in the Falklands. Bird diversity is lower on islands with rats and two vulnerable passerine species, Troglodytes cobbi (the only endemic Falkland Islands passerine and Cinclodes antarcticus, have greatly reduced abundances and/or are absent on islands with rats. We used logistic regression models to investigate the potential factors that may determine the presence of Norway rats on 158 islands in the Falkland Islands. Our models included island area, distance to the nearest rat-infested island, island location, and the history of island use by humans as driving variables. Models best supported by data included only distance to the nearest potential source of rats and island area, but the relative magnitude of the effect of distance and area on the presence of rats varied depending on whether islands were in the eastern or western sector of the archipelago. The human use of an island was not a significant parameter in any models. A very large fraction (72% of islands within 500 m of the nearest potential rat source had rats, but 97% of islands farther than 1,000 m away from potential rat sources were free of rats.

    Full Text Available Background: Alveolar bone defects in children still have a high incidence. Conventional bone graft technique that has been used as a defect therapy is still not effective, so new techniques with tissue engineering approach are needed. Bone Morphogenetic Protein 4 (BMP4 as one of the indicators of osteogenic differentiation has not been widely studied, especially in the transplantation with combination of Stem Cells from Human Exfoliated Deciduous (SHED and carbonate apatite. Aim and Objectives: This research aimed to determine the expression of BMP4 after SHED and carbonate apatite transplantation on Rattus norvegicus. Material and Methods: The combinations of SHED and carbonate apatite were transplanted on alveolar bone defects of 4 rats (Rattus norvegicus as the treatment groups and another 4 rats were transplanted with carbonate apatite as the control groups. After 21 days, staining with Hematoxylin Eosin (HE and Immunohistochemistry (IHC BMP4 was performed. Results: BMP4 expression in the treatment groups was significantly higher when compared to the control groups. Discussion: Carbonate apatite has low crystallization rate and high osteoconductivity that produce more osteoblasts and increased BMP4 expression. Conclusion: The transplantation of SHED and carbonate apatite increased BMP4 expression as an indicator of osteogenic differentiation in rats.

    Laboratory experiments were carried out to study bioaccumulation and determine a concentration factor (CF) for technetium ({sup 95m}Tc) in the homarid crustacean Nephrops norvegicus L. The steady state CF for accumulation from seawater was estimated to be about 2000 and the biological half-time was about 50 days. The highest tissue Tc concentrations were found in the green gland and the digestive gland. Depuration following accumulation from water was slow with a half-time of about 165 days. Tc accumulation from labelled food followed a biphasic model with one compartment containing about 94 percent of the ingested activity and with a half-time of about 1 day and the second compartment containing about 6 percent of the ingested activity with a half-time of about 56 days. Most retained activity was found in the digestive gland.

    Laboratory rat Rattus norvegicus. fed on poultry growers mash plus additional protein supplements and some heavy metals, was studied for the growth and the haematological parameters. All the dietary supplements resulted in an increase in the growth of the rats. The rats, fed on growers mash and prawn meal showed the best growth within 7 weeks. Effects of diets were significantly, correlated at 0.01 level. Weight loss was recorded in case of all heavy Metal-laced diets, however, calcium sulphate-laced diets resulted in an increase in growth. Mercurous chloride was the most toxic salt which resulted in the greatest weight loss. Haematological analysis of rats revealed that RBC/sub s/ were higher in the case of heavy metal-laced diets than heavy metal-free diets. Generally, RBC counts were higher in females than in males within a group. Fish meal and prawn meal feeding. (author)

    Full Text Available Obesity is one of major nutritional problems in the world. Obesity is very dangerous, especially when concentrated in the abdomen, because it is closely linked to various diseases such as diabetes, hypertension, heart disease, which can to causing death. This study aims to identify the nature and distribution of ghrelin on gastric endocrine cells in the obese rat (Rattus norvegicus by using immunohistochemical techniques. The results will strengthen the understanding of the role and function of ghrelin as an alternative therapeutic target on obesity. The research used gastric tissues of ten obese and control rats which were stained with avidin-biotin-peroxidase complex method of immunohistochemistry. The results showed the existence of two types of ghrelin-producing cells (open and closed types on the gastric mucosa of control rats, and only one type of ghrelin producing cells (open type in obese rats. The intensity of ghrelin immunoreactive positive cells was detected weak in obese rats, but very strong in control rats. Ghrelin endocrine cells mainly distributed in the basal part of the gastric mucosa of the fundus parts, with a very small number in obese rats, but highly abundant in control rats. This study confirmed the decrease of the ghrelin synthesis and secretion in obese rat (Rattus norvegicus at the cellular level. The decrease of ghrelin synthesis is characterized by a reduction on the number of ghrelin producing cells, the disappearance of the close type of ghrelin producing cells, and the low activity of protein synthesis in the ghrelin producing cells. Ghrelin endocrine cells distributed mainly in the basal part of the gastric mucosa, especially in the fundus parts.

The major groups observed (frequency of occurrence method in the stomachs of Nephrops norvegicus were decapod crustaceans, other crustaceans (euphausids and peracarids and fish. The results obtained showed no significant differences between sites or seasons, and can be considered very consistent. All major taxa were present in the diet at all sites and for all seasons, a fact that can be explained by the great similarity of the bathyal fauna in all sites, which provide a major trophic resource for N. norvegicus. The percentage of fullness was also estimated per site and season, and we registered a clear decrease of this value during the summer period for all sites, except the Tyrrheanian Sea, where the lowest value was found in autumn. PCA - analysis did not clearly separate the regions (sites. The Shannon-Weaver (H´, index of diversity, was also determined per site and season, and we found a significant difference between the values of the Atlantic coast and the Western Mediterranean when compared with those of the Eastern Mediterranean.

    Full Text Available Abstract Background In this study, we investigate the effects of microcurrent stimulation on the repair process of xiphoid cartilage in 45-days-old rats. Methods Twenty male rats were divided into a control group and a treated group. A 3-mm defect was then created with a punch in anesthetized animals. In the treated group, animals were submitted to daily applications of a biphasic square pulse microgalvanic continuous electrical current during 5 min. In each application, it was used a frequency of 0.3 Hz and intensity of 20 μA. The animals were sacrificed at 7, 21 and 35 days after injury for structural analysis. Results Basophilia increased gradually in control animals during the experimental period. In treated animals, newly formed cartilage was observed on days 21 and 35. No statistically significant differences in birefringent collagen fibers were seen between groups at any of the time points. Treated animals presented a statistically larger number of chondroblasts. Calcification points were observed in treated animals on day 35. Ultrastructural analysis revealed differences in cell and matrix characteristics between the two groups. Chondrocyte-like cells were seen in control animals only after 35 days, whereas they were present in treated animals as early as by day 21. The number of cuprolinic blue-stained proteoglycans was statistically higher in treated animals on days 21 and 35. Conclusion We conclude that microcurrent stimulation accelerates the cartilage repair in non-articular site from prepuberal animals.

    Full Text Available Parasitic infections of rodents can compromise scientific research as well as the health of the animals and humans. Based on previous studies, infection rate of parasitic helminths is different in various regions of Iran. The current survey was aimed to determine endoparasitic helminths infection in 138 trapped rodents of Kermanshah county, Iran. Mice and rats were trapped using metal snares from January to October 2011 and euthanized. Rodents included 110 Mus musculus (79.00%, 23 Rattus norvegicus (17.00%, and five Rattus rattus (4.00%. The gastrointestinal and respiratory tracts were removed and examined to identify parasitic helminths. The results indicated that 42.02% of examined rodents were infected with eight helminths species, i.e. Trichuris muris (14.49%, Syphacia obvelata (13.76%, Syphacia muris (2.89%, Aspicularis tetrapetra (5.07%, Heterakis spumosa (5.07%, Capillaria hepatica eggs (3.62%, Hyminolepis diminuta (12.30%, and Cystisercus fasciolaris, the larva of Taenia teanieformis (4.34%. Given the results of this study, we concluded that examined rodents were more infected with nematodes than other helminths. As rodents are usually infected with a number of zoonotic parasites, hence control of these animals has an important role in safeguarding public health.

    Full Text Available A comparative study of the growth of Nephrops norvegicus among different areas in the Mediterranean Sea and the adjacent Atlantic was conducted. MIX and Bhattacharya´s length-based methods were used for age determination. Both methods were used for all the studied areas. For the estimation of the growth parameters two non-linear methods, based on the results of the length frequency analysis, were used; the Gauss-Newton method, implemented by the SAS program, was applied using the results of the MIX and the FISHPARM program using the results of the Bhattacharya´s method. The identification of the age groups and their mean lengths-at-age as well as the estimation of the growth parameters proved to be difficult. A question regarding the adequacy of the von Bertalanffy model was also posed. Remarkable differences were obvious between sexes in the number of identified age groups and their mean lengths-at-age as well as in their growth parameters in all areas. The comparison of the results obtained for the studied areas showed differences, which could not be considered very important except in the case of the Nephrops population of the Alboran Sea, which was characterised by a high growth rate. All other areas seemed to be close; among them the populations from Euboikos Gulf and Catalan Sea being the most different.

    The distribution of total arsenic in different portions of Norway lobster (Nephrops norvegicus L., Crustacea) was studied both in fresh samples and after a boiling process. All individuals (n = 80) were selected of medium standard commercial size (13-15 cm). The highest mean concentrations (26.86 ± 1.57 mg/kg wet weight (ww)) were found in the raw brown meat of the crustacean, probably due to its detoxification role, whereas the lowest mean values (15.97 ± 0.85 mg/kg ww) were in the raw exoskeleton. The raw white meat reported mean values of 16.09 ± 0.61 mg/kg ww. The levels of arsenic contamination detected in the boiled portions showed a significant (p < 0.01) decrease compared to the raw portions, as a consequence of solubilization phenomena. In fact, a large amount of arsenic from raw lobsters was transferred to the corresponding boiling broth. In the most commonly consumed portion, the white meat, only slight losses (7.22%) in total arsenic content were observed compared to the raw portion.

    Full Text Available We studied the effects of maternal proteic desnutrition on the neurons of the myenteric plexus of the jejunum of rats from Rattus norvegicus species. It was used litters of female rats which received diet with normal proteic level during gestation and lactation (group NN, normal diet during gestation and hypoproteic diet during lactation (group ND; hypoproteic diet during gestation and normal diet during lactation (group DN; hypoproteic diet during both gestation and lactation (group DD. After weaning all the animals received diet of normal proteic level until the 60th day of age, when they were killed. The jejunum of the animals was subjected to whole-mount preparations stained by the method of Giemsa and used for the morphologic and quantitative analyses of the neurons of the myenteric plexus. We verified that maternal proteic malnutrition does not cause decrease on the number of myenteric neurons per unit area of jejunum in rats, but elicits mechanisms which assure that, when the animal again receives normal proteic level diet (22% there occurs storage of proteic material on the cytoplasm of the neurons, thus rendering them larger and strongly basophylic.Estudamos os efeitos da desnutrição protéica materna sobre os neurônios do plexo mientérico do jejuno de ratos da espécie norvegicus.

    Angiostrongylus cantonensis, the rat lungworm, is one etiological agent of eosinophilic meningoencephalitis in humans. This zoonosis is frequently found in Asia and, more recently, in North America, Caribbean Island and northeastern of South America. Until now, research of A. cantonensis in southern, southeastern and northeastern regions of Brazil has been found natural infections only terrestrial and freshwater intermediate snail hosts (Achatina fulica, Sarasinula marginata, Subulina octona, Bradybaena similaris and Pomacea lineate). In this study, we examined the occurrence of helminthes in the synantropic rodents Rattus rattus and Rattus norvegicus in northern Brazil, focusing on the role of these species as vertebrate hosts of A. cantonensis and A. fulica as intermediate host have found natural. Thirty specimens of R. rattus and twelve of R. norvegicus were collected in the Guamá and Jurunas neighborhoods of the city of Belém, in the Brazilian state of Pará, of which almost 10% harbored adult worms in their pulmonary arteries. Sympatric A. fulica were found to be infected by L(3) larvae, which experimental infection confirmed to be A. cantonensis. Natural infection of snails and rodents with A. cantonensis was confirmed through morphological and morphometrical analyses of adults and larvae using light microscopy, scanning electron microscopy and molecular sequences of partial Cytochrome Oxidase subunit I. Phylogenetic analyses showed that A. cantonensis isolated from Pará, Brazil is similar to Japan isolate; once these specimens produced a single haplotype with high bootstrap support with Rio de Janeiro isolate. This study confirms that A. cantonensis is now endemic in northern Brazil, and that R. rattus and R. norvegicus act as natural definitive hosts, and A. fulica as the intermediate host of the parasite in this region.

    Full Text Available Toxocara cati is a common feline parasite transmitted by the ingestion of embryonated eggs, by the transmammary route or by predation of paratenic hosts harbouring third-stage larvae in their bodies. In the present study, the larval distribution of T. cati in tissues and organs of Rattus norvegicus experimentally infected with 300 embryonated eggs was analysed. Third-stage larvae were recovered from livers, lungs, kidneys, eyes, brains and carcasses of infected rats, following tissue digestion with HCl 0.5% for 24 h at 37°C. Some differences from the known larval distribution of Toxocara canisin the same rodent species were found.

    Movement of individuals promotes colonization of new areas, gene flow among local populations, and has implications for the spread of infectious agents and the control of pest species. Wild Norway rats (Rattus norvegicus) are common in highly urbanized areas but surprisingly little is known of their population structure. We sampled individuals from 11 locations within Baltimore, Maryland, to characterize the genetic structure and extent of gene flow between areas within the city. Clustering methods and a neighbour-joining tree based on pairwise genetic distances supported an east-west division in the inner city, and a third cluster comprised of historically more recent sites. Most individuals (approximately 95%) were assigned to their area of capture, indicating strong site fidelity. Moreover, the axial dispersal distance of rats (62 m) fell within typical alley length. Several rats were assigned to areas 2-11.5 km away, indicating some, albeit infrequent, long-distance movement within the city. Although individual movement appears to be limited (30-150 m), locations up to 1.7 km are comprised of relatives. Moderate F(ST), differentiation between identified clusters, and high allelic diversity indicate that regular gene flow, either via recruitment or migration, has prevented isolation. Therefore, ecology of commensal rodents in urban areas and life-history characteristics of Norway rats likely counteract many expected effects of isolation or founder events. An understanding of levels of connectivity of rat populations inhabiting urban areas provides information about the spatial scale at which populations of rats may spread disease, invade new areas, or be eradicated from an existing area without reinvasion.

    Full Text Available Background: In the field of dentistry, alveolar bone damage can be caused by periodontal disease, traumatic injury due to tooth extraction, cyst enucleation, and tumor surgery. One of the ways to regenerate the bone defect is using graft scaffold. Thus, combination of chitosan and collagen can stimulate osteogenesis. Purpose: The aim of this study was to examine the potential of chitosan combined with chicken shank collagen on bone defect regeneration process. Method: Twelve Rattus norvegicus were prepared as animal models in this research. A bone defect was intentionally created at both of the right and left femoral bones of the models. Next, 24 samples were divided into four groups, namely Group 1 using chitosan – collagen scaffold (50:50, Group 2 using chitosan collagen-scaffold (80:20, Group 3 using chitosan scaffold only, and Control Group using 3% CMC-Na. On 14th day, those animals were sacrificed, and histopathological anatomy examination was conducted to observe osteoclast cells. In addition, immunohistochemistry examination was also performed to observe RANKL expressions. Result: There was a significant difference in RANKL expressions among the groups, except between Group 3 using chitosan scaffold only and control group (p value > 0.05. The highest expression of RANKL was found in Group 1 with chitosan – collagen scaffold (50:50, followed by Group 2 with chitosan-collagen scaffold (80:20. Moreover, there was also a significant difference in osteoclast generation, except between Group 1 using chitosan – collagen scaffold (50:50 and Group 2 using chitosan-collagen scaffold (80:20, p value 0.05. Less osteoclast was found in the groups using chitosan – collagen scaffold (Group 1 and Group 2. Conclusion: Combination of chitosan and chicken shank collagen scaffold can improve regeneration process of bone defect in Rattus novergicus animals through increasing of RANKL expressions, and decreasing of osteoclast.

    Gastrointestinal helminths of Norway rat (Rattus norvegicus) from the Belgrade area were studied as a part of a wider ecological research of rats in Serbia (data on the distribution, population ecology, economic and epizoothiological-epidemiological importance, and density control). Rats were captured from May 2005 to July 2009 at both urban and suburban-rural sites. Of a total of 302 trapped rats 48% were males and 52% females, with 36.5% and 38.8% of juvenile-subadult individuals, per sex respectively. Intestinal helminth infection was noted in 68.5% of rats, with a higher prevalence in male hosts and in adult individuals. Higher numbers of infected juveniles-subadults were noted in suburban-rural habitats, while an opposite tendency was noted in adult rats. Seven helminth species were recovered, of which five were nematode (Heterakis spumosa, Nippostrongylus brasiliensis, Capillaria sp., Trichuris muns and Syphacia muris) and two cestode species (Hymenolepis diminuta and Rodentolepis fraterna). The most prevalent parasites were Heterakis spumosa (36.7%) and Hymenolepis diminuta (30.5 %). Sex and habitat-related differences were noted in the prevalence of infection with Capillaria sp. and Trichuris muris, while there were no age-related differences in the prevalence of infection with any individual helminth species. Significantly higher prevalence of infection was noted in summer as compared to spring or winter, with a tendency to be higher in autumn as compared to spring. The only significant difference in the prevalence of infection between habitat-related was noted during spring. H. spumosa was most prevalent in summer, while H. diminuta and N. brasiliensis in autumn. The mean intensity of infection with H. spumosa, R. fraterna, S. muris and T muris was higher in autumn than in the other seasons, while N. brasiliensis and Capillaria sp. occured in winter. No more than four helminth species were found in one host.

    Full Text Available Leptospira interrogans is a bacterial zoonosis with a worldwide distribution for which rats (Rattus spp. are the primary reservoir in urban settings. In order to assess, monitor, and mitigate the risk to humans, it is important to understand the ecology of this pathogen in rats. The objective of this study was to characterize the ecology of L. interrogans in Norway rats (Rattus norvegicus in an impoverished inner-city neighborhood of Vancouver, Canada.Trapping was performed in 43 city blocks, and one location within the adjacent port, over a 12 month period. Kidney samples were tested for the presence of L. interrogans using PCR and sequencing. A multivariable model was built to predict L. interrogans infection status in individual rats using season and morphometric data (e.g., weight, sex, maturity, condition, etc. as independent variables. Spatial analysis was undertaken to identify clusters of high and low L. interrogans prevalence. The prevalence of L. interrogans varied remarkably among blocks (0-66.7%, and spatial clusters of both high and low L. interrogans prevalence were identified. In the final cluster-controlled model, characteristics associated with L. interrogans-infection in rats included weight (OR = 1.14, 95% CI = 1.07-1.20, increased internal fat (OR = 2.12, 95% CI = 1.06-4.25, and number of bite wounds (OR = 1.20, 95% CI = 0.96-1.49.Because L. interrogans prevalence varied with weight, body fat, and bite wounds, this study suggests that social structure and interactions among rats may influence transmission. The prevalence and distribution of L. interrogans in rats was also highly variable even over a short geographic distance. These factors should be considered in future risk management efforts.

    Brown rats are one of the most widespread urban species worldwide. Despite the nuisances they induce and their potential role as a zoonotic reservoir, knowledge on urban rat populations remains scarce. The main purpose of this study was to characterize an urban brown rat population from Chanteraines park (Hauts-de-Seine, France), with regards to haematology, population genetics, immunogenic diversity, resistance to anticoagulant rodenticides, and community of parasites. Haematological parameters were measured. Population genetics was investigated using 13 unlinked microsatellite loci. Immunogenic diversity was assessed for Mhc-Drb. Frequency of the Y139F mutation (conferring resistance to rodenticides) and two linked microsatellites were studied, concurrently with the presence of anticoagulant residues in the liver. Combination of microscopy and molecular methods were used to investigate the occurrence of 25 parasites. Statistical approaches were used to explore multiple parasite relationships and model parasite occurrence. Eighty-six rats were caught. The first haematological data for a wild urban R. norvegicus population was reported. Genetic results suggested high genetic diversity and connectivity between Chanteraines rats and surrounding population(s). We found a high prevalence (55.8%) of the mutation Y139F and presence of rodenticide residues in 47.7% of the sampled individuals. The parasite species richness was high (16). Seven potential zoonotic pathogens were identified, together with a surprisingly high diversity of Leptospira species (4). Chanteraines rat population is not closed, allowing gene flow and making eradication programs challenging, particularly because rodenticide resistance is highly prevalent. Parasitological results showed that co-infection is more a rule than an exception. Furthermore, the presence of several potential zoonotic pathogens, of which four Leptospira species, in this urban rat population raised its role in the maintenance

    Full Text Available Aggregation is a defensive strategy employed by many prey species in response to predatory threat. Our group has characterized defensive aggregation (huddling in Rattus norvegicus in response to a ball of cat fur. In this situation some rats huddle less, and approach the threatening cue more than others (active vs. passive responders. The present study explored whether active responding is a stable phenotype associated with behaviors outside direct predatory encounters. The neural substrates of active and passive responding under predatory threat were explored using c-Fos immunohistochemistry. Finally, we examined whether the presence of conspecifics during predatory threat biases behavior towards active responding. Active and passive responding styles were found to be stable in individual rats across consecutive group exposures to cat fur, and were predicted by anxiety-like behavior in an open-field emergence test. Active responders displayed less conditioned fear in an environment associated with predatory threat, and had higher post-exposure intake of a weak sucrose solution (a test of "anhedonia". Active responding was associated with: greater cat fur-induced activation of the accessory olfactory bulb, reflecting greater olfactory stimulation in rats actively approaching the fur; lowered activation of somatosensory cortex, reflecting reduced huddling with conspecifics; and reduced activation in the lateral septum. Social exposure to cat fur promoted active responding relative to individual exposure, and lowered c-Fos expression in the dorsomedial periaqueductal grey, medial caudate putamen and lateral habenula. We conclude that individual differences in anti-predator behavior appear stable traits with active responders having a more resilient phenotype. Social exposure to predatory threat has an acute buffering effect, subtly changing the neural and behavioral response towards threat and encouraging active responding. An association between

    Urban rats present a global public health concern as they are considered a reservoir and vector of zoonotic pathogens, including Escherichia coli. In view of the increasing emergence of antimicrobial resistant E. coli strains and the on-going discussion about environmental reservoirs, we intended to analyse whether urban rats might be a potential source of putatively zoonotic E. coli combining resistance and virulence. For that, we took fecal samples from 87 brown rats (Rattus norvegicus) and tested at least three E. coli colonies from each animal. Thirty two of these E. coli strains were pre-selected from a total of 211 non-duplicate isolates based on their phenotypic resistance to at least three antimicrobial classes, thus fulfilling the definition of multiresistance. As determined by multilocus sequence typing (MLST), these 32 strains belonged to 24 different sequence types (STs), indicating a high phylogenetic diversity. We identified STs, which frequently occur among extraintestinal pathogenic E. coli (ExPEC), such as STs 95, 131, 70, 428, and 127. Also, the detection of a number of typical virulence genes confirmed that the rats tested carried ExPEC-like strains. In particular, the finding of an Extended-spectrum beta-lactamase (ESBL)-producing strain which belongs to a highly virulent, so far mainly human- and avian-restricted ExPEC lineage (ST95), which expresses a serogroup linked with invasive strains (O18:NM:K1), and finally, which produces an ESBL-type frequently identified among human strains (CTX-M-9), pointed towards the important role, urban rats might play in the transmission of multiresistant and virulent E. coli strains. Indeed, using a chicken infection model, this strain showed a high in vivo pathogenicity. Imagining the high numbers of urban rats living worldwide, the way to the transmission of putatively zoonotic, multiresistant, and virulent strains might not be far ahead. The unforeseeable consequences of such an emerging public health

    Full Text Available Falsification of the origin of livestock meat and its processed with rat meat is a problem that must be overcome to ensure food safety. One way that is often used to detect forgeries by using cytochrome b gene as a marker. The purpose of this study was to create a specific primer derived from cytochrome b sequences in rat (Rattus norvegicus as the DNA marker to detect any contamination of rat meat on fresh livestock meat and its processed meat products. Meatballs were made from beef meat with the addition of rat 1%-25%, and the meatballs were obtained from traditional markets. DNA extraction was conducted from seven species (goat, chicken, cattle, sheep, pig, horse, and rat by using phenol-chloroform. The highest success rate in detecting the presence of rat meat in a mixture of beef meatballs at concentration of 15% was 100%. The specific fragment of cytochrome b gene in R. norvegicus has no similarity with the cytochrome b gene from six other species, so it can be used as molecular markers to detect the presence of rat meat contamination in the processed of meat products. Amplified fragment length for goats, chickens, cattle, sheep, pigs, horses, and rats 157, 227, 274, 331, 398, 439 and 603 bp respectively. The amplification of cytochrome b gene in seven species of animals with different fragment length indicated the specificity of cytochrome b gene sequences among species.

    Compassion, professional ethics, and public sensitivity require that animals are euthanized humanely and appropriately under both planned and emergent situations. According to the 2013 AVMA Guidelines for the Euthanasia of Animals, intraperitoneal injection of ethanol is "acceptable with conditions" for use in mice. Because only limited information regarding this technique is available, we sought to evaluate ethanol by using ECG and high-definition video recording. Mice (n = 85) and rats (n = 16) were treated with intraperitoneal ethanol (70% or 100%), a positive-control agent (pentobarbital-phenytoin combination [Pe/Ph]), or a negative-control agent (saline solution). After injection, animals were assessed for behavioral and physiologic responses. Pain-assessment techniques in mice demonstrated that intraperitoneal injection of ethanol was not more painful than was intraperitoneal Pe/Ph. Median time to loss of consciousness for all mice that received ethanol or Pe/Ph was 45 s. Median time to respiratory arrest was 2.75, 2.25, and 2.63 min, and time (mean ± SE) to cardiac arrest was 6.04 ± 1.3, 2.96 ± 0.6, and 4.03 ± 0.5 min for 70% ethanol, 100% ethanol, and Pe/Ph, respectively. No mouse that received ethanol or Pe/Ph regained consciousness. Although successful in mice, intraperitoneal ethanol at the doses tested (9.2 to 20.1 g/kg) was unsuitable for euthanasia of rats (age, 7 to 8 wk) because of the volume needed and prolonged time to respiratory effects. For mice, intraperitoneal injection of 70% or 100% ethanol induced rapid and irreversible loss of consciousness, followed by death, and should be considered as "acceptable with conditions."

    Full Text Available Urban rats present a global public health concern as they are considered a reservoir and vector of zoonotic pathogens, including Escherichia coli. In view of the increasing emergence of antimicrobial resistant E. coli strains and the on-going discussion about environmental reservoirs, we intended to analyse whether urban rats might be a potential source of putatively zoonotic E. coli combining resistance and virulence. For that, we took fecal samples from 87 brown rats (Rattus norvegicus and tested at least three E. coli colonies from each animal. Thirty two of these E. coli strains were pre-selected from a total of 211 non-duplicate isolates based on their phenotypic resistance to at least three antimicrobial classes, thus fulfilling the definition of multiresistance. As determined by multilocus sequence typing (MLST, these 32 strains belonged to 24 different sequence types (STs, indicating a high phylogenetic diversity. We identified STs, which frequently occur among extraintestinal pathogenic E. coli (ExPEC, such as STs 95, 131, 70, 428, and 127. Also, the detection of a number of typical virulence genes confirmed that the rats tested carried ExPEC-like strains. In particular, the finding of an Extended-spectrum beta-lactamase (ESBL-producing strain which belongs to a highly virulent, so far mainly human- and avian-restricted ExPEC lineage (ST95, which expresses a serogroup linked with invasive strains (O18:NM:K1, and finally, which produces an ESBL-type frequently identified among human strains (CTX-M-9, pointed towards the important role, urban rats might play in the transmission of multiresistant and virulent E. coli strains. Indeed, using a chicken infection model, this strain showed a high in vivo pathogenicity. Imagining the high numbers of urban rats living worldwide, the way to the transmission of putatively zoonotic, multiresistant, and virulent strains might not be far ahead. The unforeseeable consequences of such an emerging public

    Full Text Available ABSTRACT The background of this study is to visualize histopathological changes on aorta of cirrhosis rats (Rattus norvegicus induced by endotoxin E. coli O55 : B5 This study was a laboratory experimental using complete randomized design with five treatments and five repetitions. Twenty five male Wistar rats were used as experimental model of cirrhosis by bile duct ligation (BDL technique. Three weeks after BDL, all cirrhosis experimental models were induced with a single intra venous injection of Eschericia coli endotoxin (3mg/kg b.b in 1 ml sterile saline, except those of five control rats that induced with sterile saline at the same volume only. Aortas of control rats group were excised at 6 hours after induction with sterile saline, whereas the other four groups were done at 6, 12, 18 and 24 hours after induction with endotoxin. The quantity of endothelial cell, discontinuity increment and the thickness of internal elastic lamina layer were observed to know histopathological changes on aorta. Histopathological changes were observed using a light mycroscope, dyscontinuity and thickness of internal elastic lamina were measured by reticular micrometer. The quantity of endothelial cell on control and observation interval of 6 and 12 hours as significant difference (P<0.05, which are bigger than that of 18 and 24 hours. Rats in the control group have the biggest quantity comparing to the other treatments. Discontinuity and thickness of internal elastic lamina layer had significant difference (P<0.05 on control, observation on 6 and 12 hours compared to observation on 18 and 24 hours after being induced with endotoxine. The highest discontinuity and the thinnest elastic lamina internal were obtained within observation on 24 hours. VCAM-1 expression on control group differ from observation on 6 and 12hours but all of them have significant difference to observation on 18 and 24 hours (P<0,05. The decrease of endothelial cell number is caused by

The endothelium contributes to the control of many vascular functions, and clinical observations show that it is a primary target for diabetic syndrome. To get better insight into the mechanisms underlying atherosclerosis, we studied the interspecific differences in the arterial metabolisms of two, Psammomys obesus and Gerbillus gerbillus, as well as Rattus norvegicus (Wistar rat, well known for its atheroresistance. Twenty-two enzymatic activities and six macromolecular substances were histochemically compared in the two desert species and in Wistar aortas (abdominal and thoracic and arteries (femoral and caudal embedded in a common block. In the healthy adult rodents, enzyme activities were very intense. They demonstrated that aortic myocytes are capable of various synthesis and catabolism processes. However, considering the frequency of atherosclerosis and its phenotypes, significant differences appeared between the species studied. Our comparative study shows that aortic atherosensitive animals have several common metabolic characteristics, which are found in Psammomys rich in metachromatic glycosaminoglycans (involved in the inhibition of lipolysis and in calcification of the organic matrix, reduced activity in enzymes related to the Krebs cycle (weakening energetic power, and low lipolytic enzyme, adenosine triphosphatase, and adenosine diphosphatase activities

    Combating heart disease is one of the challenging problems of biomedical science today. Towards this goal an indigenous preparation 'Trikatu' (a herbal combination containing Piper longum (fruit), Piper nigrum (fruit) and Zingiber officinale (rhizome) dry powder) was fed to normal and cholesterol fed male Rattus norvegicus to ascertain its efficacy as a hypolipidaemic agent. Its effects on body weight, blood and tissue (aortic, cardiac and hepatic) lipids--total, free and esterified cholesterol, low density lipoprotein(LDL) and high density lipoprotein(HDL) cholesterol, triglycerides and phospholipids--and the atherogenic index were measured. It was found that 'Trikatu' by virtue of its ability to reduce triglycerides and LDL cholesterol and to increase HDL cholesterol can reduce the risk of hyperlipidaemia and atherosclerosis. Hence 'Trikatu' can be used as a potent hypolipidaemic agent and it can reduce the atherosclerosis associated with a high fat diet. 2004 John Wiley & Sons, Ltd.

    Urban slum environments in the tropics are conducive to the proliferation and the spread of rodent-borne zoonotic pathogens to humans. Calodium hepaticum (Brancroft, 1893) is a zoonotic nematode known to infect a variety of mammalian hosts, including humans. Norway rats (Rattus norvegicus) are considered the most important mammalian host of C. hepaticum and are therefore a potentially useful species to inform estimates of the risk to humans living in urban slum environments. There is a lack of studies systematically evaluating the role of demographic and environmental factors that influence both carriage and intensity of infection of C. hepaticum in rodents from urban slum areas within tropical regions. Carriage and the intensity of infection of C. hepaticum were studied in 402 Norway rats over a 2-year period in an urban slum in Salvador, Brazil. Overall, prevalence in Norway rats was 83% (337/402). Independent risk factors for C. hepaticum carriage in R. norvegicus were age and valley of capture. Of those infected the proportion with gross liver involvement (i.e. >75% of the liver affected, a proxy for a high level intensity of infection), was low (8%, 26/337). Sixty soil samples were collected from ten locations to estimate levels of environmental contamination and provide information on the potential risk to humans of contracting C. hepaticum from the environment. Sixty percent (6/10) of the sites were contaminated with C. hepaticum. High carriage levels of C. hepaticum within Norway rats and sub-standard living conditions within slum areas may increase the risk to humans of exposure to the infective eggs of C. hepaticum. This study supports the need for further studies to assess whether humans are becoming infected within this community and whether C. hepaticum is posing a significant risk to human health.

    Full Text Available There is growing interest in developing automated, non-invasive techniques for long-lasting, laboratory-based monitoring of behaviour in organisms from deep-water continental margins which are of ecological and commercial importance. We monitored the burrow emergence rhythms in the Norway lobster, Nephrops norvegicus, which included: a characterising the regulation of behavioural activity outside the burrow under monochromatic blue light-darkness (LD cycles of 0.1 lx, recreating slope photic conditions (i.e. 200-300 m depth and constant darkness (DD, which is necessary for the study of the circadian system; b testing the performance of a newly designed digital video-image analysis system for tracking locomotor activity. We used infrared USB web cameras and customised software (in Matlab 7.1 to acquire and process digital frames of eight animals at a rate of one frame per minute under consecutive photoperiod stages for nine days each: LD, DD, and LD (subdivided into two stages, LD1 and LD2, for analysis purposes. The automated analysis allowed the production of time series of locomotor activity based on movements of the animals’ centroids. Data were studied with periodogram, waveform, and Fourier analyses. For the first time, we report robust diurnal burrow emergence rhythms during the LD period, which became weak in DD. Our results fit with field data accounting for midday peaks in catches at the depth of slopes. The comparison of the present locomotor pattern with those recorded at different light intensities clarifies the regulation of the clock of N. norvegicus at different depths.

The study was carried out on 48 poultry farms between spring 1999 and winter 2001. The study of opossums began in winter 2000. During the study period we captured 152 Rattus norvegicus, 3 Rattus rattus, 16 Didelphis albiventris and 1 Lutreolina crassicaudata. We have registered the presence of rats and opossums in 70% and 27% of the studied farms, respectively. The percentage of farms with rats was independent of the presence or absence of pigs. We did not detect the presence of Leptospira spp. and Trichinella spiralis in any individual. We detected the presence of Salmonella Enteritidis in one Rattus norvegicus and one Didelphis albiventris. According to our results, the rats and opossums of poultry farms may not report a risk factor in the transmission of Trichinella and Leptospira under the present conditions; but the detection of Salmonella Enteritidis in rats as well as in opossums suggests the idea of applying prophylactics measurements on poultry farms.A prevalência de Trichinella spiralis, Leptospira spp. e Salmonella spp. foi estudada em ratos e gambás que habitam granjas avícolas da região de Exaltación de la Cruz, Buenos Aires, Argentina, com o objetivo de determinar o potencial risco sanitário para pessoas que ficam em contato com esses animais.

    Prey species show specific adaptations that allow recognition, avoidance, and defense against predators. This study was undertaken to investigate the processing of a chronic, life-threatening stimulus to Norway rats ( Rattus norvegicus). One hundred forty-four Norway rats were tested by repeated presentation of cat urine for 1 h at different days in a defensive withdrawal apparatus. Rats exposed to urine for short periods showed significantly larger defensive behavioral and medial hypothalamic c-fos messenger RNA (mRNA) responses than other groups. These defensive responses habituated shortly after the presentation of cat urine. Serum levels of adrenocorticotropic hormone and corticosterone increased significantly when animals were repeatedly exposed to cat urine. However, the hormonal responses took longer to habituate than the behavioral and molecular responses did. We conclude that the behavioral and c-fos mRNA responses are "primed" for habituation to repeated exposures to cat urine, while the hormonal responses show "resistance." The results support our hypothesis that the strongest anti-predator responses at three levels would occur during short-term exposure to cat urine and that these responses would subsequently disappear on prolonged exposure. This study assists understanding the way in which the different levels of defensive responses are integrated and react during chronic stress.

    Abstract. We studied the main species of ants associated with carcasses of Rattus norvegicus (Berkenhout during the decomposition process, in different seasons in a savannah area. In each of the four seasons a carcass was disposed in the field and we installed around it five pitfall traps. Ants were collected from the tray containing the carcass and from the traps daily, until the end of decomposition in each season. Ants belonging to twenty-three species, with 63.85% of the total individuals collected in the traps and the rest directly in the trays, were sampled. The presence of predatory and nectarivorous species were registered. The scarcity of available resources in the environment in the dry season possibly makes the carcasses important food sources, explaining the higher richness of active species near the trays (collected in the pitfall traps. This increased activity is also reflected in a higher number of species and individuals in the carcasses. The opposite also seems to occur once in the autumn, end of wet season, we observed lower abundance of ants in the carcasses. The presence of ants on carcasses throughout all stages of the decomposition process and in all seasons of the year highlighted the importance of the association between representatives of this taxon and carcasses in Cerrado environments.

    The objective of the current attempt was to investigate the suitability of wild-living rats (Rattus norvegicus) as a passive bioindicator using quantitative determinations of 12 chemical elements in different organs taken from rats which were caught in the Zoological Garden of Zittau. Aside from the determinations of so-called background levels, the focus of interest was with accumulations of certain elements within the organs depending on either sex or age of the rats. There were different affinities of the elements towards certain organs. Because of apparent sex and age-related differences in element concentrations and accumulation features, a well-planned sampling strategy for the use of rats as possible passive bioindicators is indeed required. The consideration of element distribution patterns within the organ system of Rattus norvegicus (based on body burden calculations (in part 2 of this work)) allows an effective use of the rat for purposes of integrative monitoring.

    Diet of high lipids cause hyperlipidemia, which marked by an increase of total cholesterols, triglycerides, LDL-C, and decreasing of HDL-C. Hyperlipidemia lead the occurrence of atherosclerosis, one of factors that trigger cardiovascular disease, as hypertention; coronary heart and stroke. Parijoto (M. speciosa) is endemic plants in Asia with a distribution center in Malaysia, Indonesia and Philippines. Parijoto contain phytochemical components such as flavonoids, saponins and kardenolin. Flavonoid potensial as an antioxidants and can improve the hyperlipidemia condition. This study was aimed to determine lipid profiles and atherogenic index of hyperlipidemic Wistar rats (R. norvegicus Berkenhout, 1769) which given the methanolic extract of Parijoto (M. speciosa). The research was done with pre and post test randomized control group design. Rats were given a mixture of duck yolk and reused cooking oil (1:1) orally as much as 1% of body weight (BW) for 30 days. After hyperlipidemia achieved, rats were divided into 5 group: normal rats, hyperlipidemic rats, hyperlipidemic rats were given the methanolic extract of Parijoto (M. speciosa) 500 mg/kg, 1000 mg/kg, and 1500 mg/kg BW. Blood samples were collected when rats in hyperlipidemia conditions and after treatment with the methanolic extract of Parijoto (M. speciosa) for 30 days. The data of total cholesterol, HDL-Cholesterol, LDL-Cholesterol level, and atherogenic index were analyzed using ANOVA followed by Tukey test at 5% significance level. The result showed that giving of methanolic extract of Parijoto (M. speciosa) in hyperlipidemic rats reduced the total cholesterol, LDL-Cholesterol levels, and increased of HDL-cholesterol levels significantly (p<0.01), so atherogenic index reduced significantly too (p<0.01). Total cholesterol and LDL-Cholesterol levels were positively correlated with the atherogenic index, whereas HDL-cholesterol levels were negatively correlated with the atherogenic index.

    Background: Quail eggs contain a considerable amount of complete nutritional sources such as carbohydrates, proteins, fats, and micronutrients. However, they also have a high cholesterol level, which can potentially cause atherosclerosis and chronic heart diseases. The response of the body to foods containing is influenced by factors such as ethnicity, genetics, and hormonal and nutrient status of the consumer. The cholesterol level of quail eggs can be reduced by manipulating the feed using supplemental organic feed. Organic quail eggs have been believed to correct the lipid profile of white mice during the lactation phase. Purpose: The aim of this study was to analyze the effect of feed containing organic quail eggs on the blood lipid profile of white mice (Rattus norvegicus L.) during the lactation phase. Materials and Methods: This experimental study was conducted using a completely randomized design with four experiments and five repetitions. Experimental mice: T0 mice were used as control; T1 mice were supplemented with quail eggs produced by quails that were fed with standard feed; T2 mice were supplemented with eggs produced by quails fed with standard organic feed; and T3 mice were supplemented with eggs produced by quails fed with organic feed with the addition of cassava leaf flour, mackerel flour, and turmeric powder. Quail egg supplementation was administered to the mice from the early pregnancy period till the end of the lactation phase. The acquired data were analyzed using ANOVA. SPSS version 16.0 software for Windows was used for data analyses. Results and summary: Feeding the white mice with different compositions of organic quail egg supplements had no effect on the consumption of feed and water, body weight, and lipid profile (including total cholesterol, LDL, HDL, and triglyceride) during the lactation phase (P > 0.05).

  17. Lipid Composition of Oil Extracted from Wasted Norway Lobster (Nephrops norvegicus Heads and Comparison with Oil Extracted from Antarctic Krill (Euphasia superba

    Full Text Available In the UK, the Norway lobster (Nephrops norvegicus supports its most important shellfish fishery. Nephrops are sold either whole, or as “tails-only” for the scampi trade. In the “tailing” process, the “head” (cephalothorax is discarded as waste. A smaller crustacean species, the Antarctic krill Euphasia superba, represents an economically valuable industry, as its extractable oil is sold as a human dietary supplement. The aim of this study was to determine the amount and composition of the oil contained in discarded Nephrops heads and to compare its composition to the oil extracted from krill. Differences due to Geographical variation and seasonal patterns in the amount and composition of lipid were also noted. Results indicated that Nephrops head waste samples collected from more southern locations in Scotland (Clyde Sea area contained higher levels of oil when compared to samples collected from northern locations in Iceland. Moreover, seasonal differences within the Clyde Sea area in Scotland were also observed, with oil extracted from Nephrops head waste peaking at around 11.5% during the summer months when larger and more mature females were caught by trawl. At this time of the year, the valuable fatty acids eicosapentaenoic acid (EPA and docosahexaenoic acid (DHA accounted for around 23% of the total fatty acid content in oil extracted from Nephrops head waste. A seasonal effect on EPA content was found, with higher levels obtained in the summer, while no trend was found in DHA percentages. Finally, oil from Nephrops head waste contained a higher proportion of EPA and DHA than krill oil but these fatty acids were more abundantly linked to the neutral lipids rather to than polar lipids. The characterization of lipid that could be extracted from Nephrops head waste should be seen as a first step for the commercial use of a valuable resource currently wasted. This approach is extremely relevant given the current limited supply of

    ATP-sensitive inward rectifier potassium channels (Kir), are a potassium channel family involved in many physiological processes. K ATP dysfunctions are observed in several diseases such as hypoglycaemia, hyperinsulinemia, Prinzmetal angina-like symptoms, cardiovascular diseases. A broader view of the K ATP mechanism is needed in order to operate on their regulation, and in this work we clarify the structure of the Rattus norvegicus ATP-sensitive inward rectifier potassium channel 8 (Kir6.1), which has been obtained through a homology modelling procedure. Due to the medical use of flavonoids, a considerable increase in studies on their influence on human health has recently been observed, therefore our aim is to study, through computational methods, the three-dimensional (3D) conformation together with mechanism of action of Kir6.1 with three flavonoids. Computational analysis by performing molecular dynamics (MD) and docking simulation on rat 3D modelled structure have been completed, in its closed and open conformation state and in complex with Quercetin, 5-Hydroxyflavone and Rutin flavonoids. Our study showed that only Quercetin and 5-Hydroxyflavone were responsible for a significant down-regulation of the Kir6.1 activity, stabilising it in a closed conformation. This hypothesis was supported by in vitro experiments demonstrating that Quercetin and 5-Hydroxyflavone were capable to inhibit K ATP currents of rat tail main artery myocytes recorded by the patch-clamp technique. Combined methodological approaches, such as molecular modelling, docking and MD simulations of Kir6.1 channel, used to elucidate flavonoids intrinsic mechanism of action, are introduced, revealing a new potential druggable protein site.

  19. Spatial transferability of habitat suitability models of Nephrops norvegicus among fished areas in the Northeast Atlantic: sufficiently stable for marine resource conservation?

    Directory of Open Access Journals (Sweden)

    Valentina Lauria

    Full Text Available Knowledge of the spatial distribution and habitat associations of species in relation to the environment is essential for their management and conservation. Habitat suitability models are useful in quantifying species-environment relationships and predicting species distribution patterns. Little is known, however, about the stability and performance of habitat suitability models when projected into new areas (spatial transferability and how this can inform resource management. The aims of this study were to model habitat suitability of Norway lobster (Nephrops norvegicus in five fished areas of the Northeast Atlantic (Aran ground, Irish Sea, Celtic Sea, Scotland Inshore and Fladen ground, and to test for spatial transferability of habitat models among multiple regions. Nephrops burrow density was modelled using generalised additive models (GAMs with predictors selected from four environmental variables (depth, slope, sediment and rugosity. Models were evaluated and tested for spatial transferability among areas. The optimum models (lowest AICc for different areas always included depth and sediment as predictors. Burrow densities were generally greater at depth and in finer sediments, but relationships for individual areas were sometimes more complex. Aside from an inclusion of depth and sediment, the optimum models differed between fished areas. When it came to tests of spatial transferability, however, most of the models were able to predict Nephrops density in other areas. Furthermore, transferability was not dependent on use of the optimum models since competing models were also able to achieve a similar level of transferability to new areas. A degree of decoupling between model 'fitting' performance and spatial transferability supports the use of simpler models when extrapolating habitat suitability maps to different areas. Differences in the form and performance of models from different areas may supply further information on the processes

Assim, oito grupos de ratos machos da linhagem Wistar (Rattus norvegicus foram alimentados ad libitum por 56 dias com oito dietas distintas contendo as fontes e níveis citados de lipídios. As dosagens de colesterol total e triacilgliceróis no soro foram realizadas pelo método colorimétrico/enzimático utilizando "kit" comercial específico. O colesterol em HDL foi determinado por precipitação dos quilomícrons, VLDL e LDL, utilizando também "kit" específico. O aumento de lipídios na dieta para 14% elevou os valores de colesterol total, HDL-colesterol e LDL+VLDL-colesterol séricos, quando a fonte foi a gordura suína. Com 14% de lipídios na dieta, os menores valores de triacilgliceróis séricos foram observados nas fontes lipídicas óleo de soja e canola, com valores de 76,09 e 84,42 mg/dL, respectivamente.Four fat sources (soybean oil, canola oil, olive oil, swine fat were evaluated with regard to their influence, at two levels in the diet (7 and 14%, on some fat fractions in rats' blood. Thus, eight groups of Wistar rat (Rattus norvegicus males were ad libitum fed eight different diets, containing the fat and level reported, for 56 days. The dosages of total serum cholesterol and thriacylglicerols were performed by the colorimetric/enzymatic method utilizing a commercial specific kit. The HDL cholesterol was determined by precipitation of kilomicra (VLDL and LDL by utilizing also a specific kit. The increase of fat in the diet to 14% raised the total cholesterol contents, serum HDL cholesterol and LDL + VLDL cholesterol when the source was swine fat. With 14% of fat in the diet, the lowest values of serum triacylglycerols were found for the fat sources soybean and canola oils

    Background concentrations of eleven elements in tissues and organs of wild-living rats (Rattus norvegicus) obtained from a region (Euroregion Neisse, around the trilateral border region of Germany, Poland and the Czech Republic) distinguished by low to intermediate levels of environmental contaminations are given in part I of this work. In order to identify the most important depot compartments for certain elements, a body burden method was applied. Differences of affinity due to sex and age of analyzed rats are discussed, as are the suitability of specific organs and tissues with regard to bioaccumulation measurements concerning metals. The principal depot compartments for the heavy metals Cu, Mn, Cd, (in adult rats) and Tl are the liver and kidneys, whereas the elements Ni, Sr, Pb (for adult animals) and Ti are more affinitively to bones. Co and Zn displayed a more pronounced affinity towards tissues of the bones and liver. The analysis revealed large differences in Cd and Pb distributions both among young and adult rats, and with respect to sexes. It can be concluded that the distribution of the elements investigated in this study in free-living rats agrees with that in man, except for that of Ni. The above agreement gives proof of the possibility to use depot organs of rats for bioindication which was already mentioned in part I of this work.

    The present study was carried out to evaluate the toxic effect of blend of some food colors on Swiss albino rats. A blend (1:1:1) of sunset yellow, metanil yellow and tartrazine showed additive effects on serological parameters which indicate that addition of these dye together in food stuff may give rise to more toxic effects than are produced by each dye individually. Animals were divided into four groups (I, II, III, and IV). First group was treated as control and respective group of animals received 25, 50 and 75 mg/kg body weight blend of food colors by gavaging up to 30 days. The serological study showed a decrease in total protein and albumin and an increase in alkaline phosphatase, SGPT and total bilirubin. The results revealed that oral administration of these blend did not affect the body weight gain. The prolonged consumption of the blend may cause adverse effect on human health.

    Full Text Available In vitro antioxidant and erythrocyte protecting activities by aqueous extract of Ficus thonningii leaves on blood cells were studied in acetaminophen treated rats. The extract was safe at limit dose of 5000 mg kg-1body weight. The extract demonstrated dose dependent antihemolytic effect at dose levels between 50 and 200 mg kg-1 body weight. The lowest antihemolytic effect was observed at dose level of 200 mg kg-1 body given the lowest percentage hemolysis of 10.53 ± 1.76%, whereas the highest percentage hemolysis at dose level of 50 mg kg-1 was 29.02 ± 7.45%. Hematology revealed erythrocytosis at dose levels of 100 and 200 mg kg-1 body weight. Hyper-globinemia and lymphocytopenia were observed at dose levels of 100 mg kg-1 and 200 mg kg-1, respectively. The extract effectively showed scavenging activity on a stable oxidative radical diphenylpicrylhydrazyl (DPPH and a significant ferric reducing antioxidant power (FRAP activity. The plausible erythrocyte membrane protective effect may be due to its free radical scavenging activity and hence the extract can be used to improve hematological parameters and ameliorate oxidative stress.

    Full Text Available The histological effect of oral administration of sildenafil citrate (Viagra, commonly used as an aphrodisiac and for the treatment of erectile dysfunction on one of the visual relay centres namely the lateral geniculate body (LGB of adult Wistar rat was carefully studied. The rats of both sexes (n=24, average weight of 202g were randomly assigned into three treatment (n=18 and control (n=6 groups. The rats in the treatment groups ‘A’, ‘B’ and ‘C’ received respectively, 0.25mg/kg, 0.70mg/kg and 1.43mg/kg body weight of sildenafil citrate base dissolved in distilled water daily for 30 days, through orogastric feeding tube, while that of the control group D, received equal volume of distilled water daily during the period of the experiment. The rats were fed with growers’ mash obtained from Edo Feeds and Flour Mill Ltd, Ewu, Edo State, Nigeria and were given water liberally. The rats were sacrificed on day thirty-one of the experiment. The lateral geniculate body (LGB was carefully dissected out and quickly fixed in 10% formal saline for histological studies. The histological findings after H&E method indicated that the treated section of the lateral geniculate body (LGB showed some varying degree of reduced cellular population based on its sparse distribution, degenerative changes, cellular hypertrophy, and intercellular vacuolations appearing in the stroma. Varying dosage and long administration of sildenafil citrate may have some deleterious effects on the neurons of the intracranial visual relay centre and this may probably have some adverse effects on visual sensibilities by its deleterious effects on the cells of the lateral geniculate body (LGB of adult Wistar rats. It is therefore recommended that further studies aimed at corroborating these observations be carried out.

    Full Text Available Laboratory rats are usually kept in relatively small cages, but research has shown that they prefer larger and more complex environments. The physiological, neurological and health effects of standard laboratory housing are well established, but fewer studies have addressed the sustained emotional impact of a standard cage environment. One method of assessing affective states in animals is to look at the animals' anticipatory behaviour between the presentation of a cue signalling the arrival of a reward and the arrival of that reward. The primary aim of this study was to use anticipatory behaviour to assess the affective state experienced by female rats a reared and housed long-term in a standard laboratory cage versus a semi-naturalistic environment, and b before and after treatment with an antidepressant or an anxiolytic. A secondary aim was to add to the literature on anticipatory behaviour by describing and comparing the frequency and duration of individual elements of anticipatory behaviour displayed by rats reared in these two systems. In all experiments, total behavioural frequency was higher in standard-housed rats compared to rats from the semi-naturalistic condition, suggesting that standard-housed rats were more sensitive to rewards and experiencing poorer welfare than rats reared in the semi-naturalistic environment. What rats did in anticipation of the reward also differed between housing treatments, with standard-housed rats mostly rearing and rats from the semi-naturalistic condition mostly sitting facing the direction of the upcoming treat. Drug interventions had no effect on the quantity or form of anticipatory behaviour, suggesting that the poorer welfare experienced by standard-housed rats was not analogous to depression or anxiety, or alternatively that the drug interventions were ineffective.

    To investigate the efficacy of a 10% gel of unripe banana (Musa sapientum) peel in treating surgical wounds in rats. A longitudinal, prospective, randomized triple-blind study was conducted with 60 Wistar rats (Rattus norvegicus albinus) weighing approximately 400g. The animals were randomly divided into: control group (treated with gel containing no active ingredient) and study group (treated with 10% gel of unripe banana peel). The gel was applied every three days to a 4x4-cm surgical wound created on the back of each animal (day 0) in both groups. Tissue samples were collected for histological analysis on days 14, 21 and 28. On day 14, more extensive vascular proliferation (p=0.023), presence of mononuclear cells (p=0.000), fibroblast proliferation (p=0.012), re-epithelialization (p=0.000), and decreased presence of polymorphonuclear cells (p=0.010) were observed in the study group than in controls. No significant between-group difference in the presence of polymorphonuclear cells was found on day 21. Fibroblast proliferation was significantly greater (p=0.006) in the study group than in the control group on day 28. The 10% gel of unripe banana peel showed anti-inflammatory activity and stimulated wound healing in rat skin when compared with a gel containing no active ingredient.

    To evaluate the expression of nerve growth factor (NGF) in the urethra of adult female rats in different hormonal status using immunohistochemical assay. Forty-eight rats (Rattus norvegicus albinus, Rodentia, Mammalia) from the CEDEME-UNIFESP laboratory animal facility were used in the study. Rats were divided into four groups: group A, 12 non-neutered rats; group B, 12 oophorectomized rats; group C, 12 castrated rats treated with 17β-estradiol for 30 days; and group D, 12 aging rats. Animals were killed by lethal injection and their urethra was removed. NGF expression was evaluated by means of immunohistochemistry using mouse monoclonal primary IgG antibody anti-NGF diluted 1:600, and read under 400× magnification. Digital analysis of the images was done by Imagelab software. The intensity of the dark brown color was used as a measure of NGF cytoplasmatic expression, and was used to quantify the percentage of epithelial and muscular layer cells showing this neurotrophin. After oophorectomy, rats showed a significant increase in NGF expression in the periurethral muscular layer. Compared with oophorectomized rats, NGF expression increased in the epithelial layer and diminished in the periurethral smooth muscle following estrogen administration. In 18-month-old rats, NGF expression was diminished in both epithelial and muscular layers. Hormonal status led to significant differences in NGF protein expression in urethral epithelium and periurethral smooth muscle. Copyright © 2012 Wiley Periodicals, Inc.

    Full Text Available Aim: The aim of this study was to determine the effect of Apis mellifera propolis extract gel on vascular endothelial growth factor (VEGF and matrix metalloproteinase-9 (MMP-9 expression in the traumatic ulcers of rats afflicted with diabetes mellitus (DM. Materials and Methods: The study was conducted on 24 male Wistar rats (Rattus norvegicus induced with DM by injecting 50 mg/kg of Streptozotocin, intraperitoneally, and a traumatic ulcer on their lower lip mucosa. These were divided into eight groups: Four each for control and treatment groups. Each control and treatment group consisted of three rats. The control groups treated with hydroxypropyl methylcellulose 5% gel and treatment groups were administered with propolis extract gel. The expression of VEGF and MMP-9 was observed on days 3, 5, 7, and 9. Furthermore, mice sacrificed and the lower lip labial mucosa tissue of mice has been taken to make the histopathology anatomy preparation by means of immunohistochemical examination with monoclonal antibodies anti-VEGF and anti-MMP-9. Results: This experiment revealed higher VEGF expression and lower MMP-9 expression in the treatment group as compared to that of the control group. Analysis of Variance showed significant differences (p<0.01 of both VEGF expression and MMP-9 expression between the two groups. A Tukey's analysis did not find strong contrasts in VEGF and MMP-9 expressions between various treatment groups. However, those between treatment and control groups were found to be considerable. Conclusion: Propolis extract gel increased the expression of VEGF and decreased that of MMP-9 during the healing process of traumatic ulcers on the oral mucosa of diabetes afflicted Wistar rats (R. norvegicus.

    Type-2 diabetes mellitus (T2DM) is a degenerative disease that causes an imbalance in the metabolism. The aim of this research is to determine the influences of CSN1S2 on the structure of microglial cells in T2DM. Rats (Rattus norvegicus) were divided into eight groups of treatment with looping three times each between treatment groups (CM) Control. The control is given a milk treatment with doses of 375 mg/kg (CM375), 750 mg/kg (CM750), and 1500 mg/kg (CM1500), T2DM (DMK), and T2DM with CSN1S2 375 mg/kg dose (DM375), 750mg/kg (DM750), and 1500 mg/kg (DM1500). The animal model T2DM was induced by a high-fat diet in the form of feed followed by injection of STZ (dose of 25 mg/kg of animal treatment) and treatment of CSN1S2 for 28 days. Brain organs were taken and analysed in histopathology stained by Hematoxylin-eosin (HE) and observed using Olympus BX53. Based on the results, it was concluded that CSN1S2 protein is influential for induction of microglial cell proliferation in animal models of T2DM, as immunity responds to the inflammatory condition in T2DM.

    The aim of this study was to investigate the microbial quality of whole Norway lobster (Nephrops norvegicus) and Norway lobster tails to optimize handling conditions. This was done by assessing the total viable count (TVC) and characterizing the dominant microbiota. The cultivable microorganisms were quantified via classical microbiological plating methods. To characterize as many bacterial species present as possible, we performed advanced molecular identification techniques (PCR-DGGE). The initial TVC of fresh Norway lobster meat was high (3.0 log cfu/g) as compared to fish. No significant difference between whole Norway lobster and Norway lobster tails could be found during the storage period. From day 6 of storage, a significant difference between Plate Count Agar (PCA) and Marine Agar (MA) was observed. The microbiota of Norway lobster was dominated by members of the Gram-negative genera such as Psychrobacter spp., Pseudoalteromonas spp., Pseudomonas spp., Luteimonas spp., and Aliivibrio spp. From these bacteria, mainly Psychrobacter spp. and Pseudomonas spp. remained present until the end of the storage period. These are known spoilage organisms in fishery products. Other known spoilage organisms of crustaceans such as Photobacterium spp. could not be identified. Copyright © 2014 Elsevier Ltd.

    Increasing resistance of Haemophilus ducreyi to antimicrobials necessitates further trials of new antimicrobial agents for treating chancroid. Enoxacin has excellent in vitro activity against H ducreyi, and a randomised clinical trial of three doses of enoxacin 400 mg at intervals of 12 hours compared with a single dose of trimethoprim/sulphametrole (TMP/SMT) 640/3200 mg was therefore conducted. Of 169 men enrolled in the study, 86 received enoxacin and 83 received TMP/SMT. Ulcers were improved or cured in 65/73 men treated with enoxacin and 57/70 men treated with TMP/SMT. This difference was not significant. At 72 hours after treatment, H ducreyi was eradicated from ulcers of 72/77 men treated with enoxacin and of 67/74 of those treated with TMP/SMT. Patients with buboes responded equally well to both treatments. Of 100 H ducreyi strains tested, all were susceptible to both 0.25 mg/l enoxacin and the combination of 0.25 mg/l TMP and 5 mg/l SMT. Although most men treated with either regimen were cured, neither regimen appeared to be the optimum treatment for chancroid. This study shows the efficacy of enoxacin for a soft tissue infection caused by Gram negative organisms. PMID:3044978

    Full Text Available Cigarette smoke is one of free radical source that can cause oxidative stress, emphysema, and inflamation on lung. Leaves of Premna cordifolia Linn. is one of antioxidant that can neutralize the free radical in body. The purpose of the research  is to find the antioxidant activity of Premna cordifolia leaves in reducing lung’s damage and to find the effective dose that can reduce lung’s damage after exposure of cigarette smoke. Dried leaves of Premna cordifolia are maserated with ethanol 70%.  Rats are divided into five groups, Group without treatment (CMC control, group that exposed to smoke, three groups that treated with 200 (P1, 400 (P2, and 600mg/kgBW (P3 of ethanolic extract of Premna cordifolia leaves after smoke exposure, and one group that treated with 18mg/kgBW of vitamin E as positive control after smoke exposure. All groups were treated with three cigarette without filter for 14 days. All rat were terminated on the fifteent day. Right lung were collected and subjected to necropsy and stained with Hematoksilin-Eosin.

    1980-10-01

    Taking into account the negative influence of mine waters with suspended matter on the natural environment on the surface, the maximum treatment of mine water underground, is proposed. It is noted that full treatment of mine water, using conventional filtration methods, would be rather expensive, but a limited treatment of mine water is possible. Such treated mine water can be used in dust suppression and fire fighting systems. Mine water treated underground should be free of any odor, with pH level ranging from 6 to 9.5, with suspended matter content not exceeding 50 mg/l and coli-titre not less than 300 cm$SUP$3. It is suggested that water treatment to produce water characterized by these parameters is possible and economical. Recommendations on construction of underground sedimentation tanks and channels, and a hydraulic system of cleaning sedimentation tanks are proposed. The settling would be stored underground in abandoned workings. (2 refs.) (In Russian)

    The treatment of hydrocarbon oils, such as coal or shale oils, paraffin oils, and petroleum, either in the crude or more or less refined state has the object of reducing the specific gravity and otherwise improving the qualities of such oils. The oil to be treated is put into any ordinary still and distilled. The vapor escaping during the distillation is passed through one or more heating vessels or chambers and exposed to the heat necessary to produce the change. The heating vessels or chambers may be made of metal, clay, or any other material adapted to endure heat, and they may be made of any desired form, or they may be constituted of a coil of metal pipes or a series of tubes such as are used for heating air for blast furnaces.

  14. Treating schizophrenia during menopause.

    Science.gov (United States)

    Brzezinski, Amnon; Brzezinski-Sinai, Noa A; Seeman, Mary V

    2017-05-01

    The aim of this review is to examine three questions: What are the risks and benefits of treating women with schizophrenia with hormone therapy (HT) at menopause? Should the antipsychotic regimen be changed at menopause? Do early- and late-onset women with schizophrenia respond differently to HT at menopause? MEDLINE databases for the years 1990 to 2016 were searched using the following interactive terms: schizophrenia, gender, menopause, estrogen, and hormones. The selected articles (62 out of 800 abstracts) were chosen on the basis of their applicability to the objectives of this targeted narrative review. HT during the perimenopause in women with schizophrenia ameliorates psychotic and cognitive symptoms, and may also help affective symptoms. Vasomotor, genitourinary, and sleep symptoms are also reduced. Depending on the woman's age and personal risk factors and antipsychotic side effects, the risk of breast cancer and cardiovascular disease may be increased. Antipsychotic types and doses may need to be adjusted at menopause, as may be the mode of administration. Both HT and changes in antipsychotic management should be considered for women with schizophrenia at menopause. The question about differences in response between early- and late-onset women cannot yet be answered.

    Giardiasis infection may be asymptomatic, or can cause diarrhoea (sometimes severe), weight loss, malabsorption, and, in children, failure to thrive. It is usually treated with metronidazole given three times daily for five to 10 days. To evaluate the relative effectiveness of alternative antibiotic regimens for treating adults or children with symptomatic giardiasis. We searched the Cochrane Infectious Disease Group Specialized Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 6 2012); MEDLINE, EMBASE, LILACS and the International Clinical Trials Registry Platform Search Portal (3 July 2012). We included randomized controlled trials (RCT) comparing metronidazole administered for five to 10 days with any of the following drugs: metronidazole (single dose), tinidazole, albendazole, mebendazole, and nitazoxanide. The primary outcomes were parasitological and clinical cure. Two authors independently assessed studies for inclusion, performed the risk of bias assessment, and extracted data. We summarized data using risk ratios and mean differences and we presented the results in forest plots and performed meta-analyses where possible. We assessed heterogeneity using the Chi(2) test, I(2) statistic and visual inspection; and we explored this by using subgroup analyses.We assessed the quality of evidence by using the GRADE approach. We included 19 trials, involving 1817 participants, of which 1441 were children. Studies were generally small, with poor methods reporting. . Most reported parasitological outcomes rather than clinical improvement.Ten trials, from India, Mexico, Peru, Iran, Cuba, and Turkey, compared albendazole (400 mg once daily for five to 10 days) with metronidazole (250 mg to 500 mg three times daily for five to 10 days). This once-daily regimen of albendazole is probably equivalent to metronidazole at achieving parasitological cure (RR 0.99, 95% CI 0.95 to 1.03; 932 participants, 10 trials; moderate quality evidence), and

    The aim of the present study was to determine whether low-level laser therapy (LLLT) in conjunction with aerobic training interferes with oxidative stress, thereby influencing the performance of old rats participating in swimming. Thirty Wistar rats (Norvegicus albinus) (24 aged and six young) were tested. The older animals were randomly divided into aged-control, aged-exercise, aged-LLLT, aged-LLLT/exercise, and young-control. Aerobic capacity (VO2max(0.75)) was analyzed before and after the training period. The exercise groups were trained for 6 weeks, and the LLLT was applied at 808 nm and 4 J energy. The rats were euthanized, and muscle tissue was collected to analyze the index of lipid peroxidation thiobarbituric acid reactive substances (TBARS), glutathione (GSH), superoxide dismutase (SOD), and catalase (CAT) activities. VO2 (0.75)max values in the aged-LLLT/exercise group were significantly higher from those in the baseline older group (p exercise group (p exercise group than those in the LLLT and exercise groups. Young animals presented lesser and statistically significant activities of antioxidant enzymes compared to the aged group. The LLLT/exercise group and the LLLT and exercise group could also mitigate the concentration of TBARS (p > 0.05). Laser therapy in conjunction with aerobic training may reduce oxidative stress, as well as increase VO2 (0.75)max, indicating that an aerobic exercise such as swimming increases speed and improves performance in aged animals treated with LLLT.

    ), adjunct acupuncture therapy reduced pain at one month after treatment: mean pain was 8 points on a 0 to 10 point scale in the standard therapy group; treatment reduced pain by 3 points (95% CI −3.9 to −2.1), an absolute reduction of 30% (21% to 39%). Two people treated with acupuncture reported adverse events; there were none in the control group (RR 3.57; 95% CI 0.18 to 71.21). Global well-being, sleep, fatigue and stiffness were not reported. Physical function data were not usable. Low quality evidence from one study (38 participants) showed a short-term benefit of acupuncture over antidepressants in pain relief: mean pain was 29 points (0 to 100 point scale) in the antidepressant group; acupuncture reduced pain by 17 points (95% CI −24.1 to −10.5). Other outcomes or adverse events were not reported. Moderate-quality evidence from one study (41 participants) indicated that deep needling with or without deqi did not differ in pain, fatigue, function or adverse events. Other outcomes were not reported. Four studies reported no differences between acupuncture and control or other treatments described at six to seven months follow-up. No serious adverse events were reported, but there were insufficient adverse events to be certain of the risks. Authors’ conclusions There is low tomoderate-level evidence that compared with no treatment and standard therapy, acupuncture improves pain and stiffness in people with fibromyalgia. There is moderate-level evidence that the effect of acupuncture does not differ from sham acupuncture in reducing pain or fatigue, or improving sleep or global well-being. EA is probably better than MA for pain and stiffness reduction and improvement of global well-being, sleep and fatigue. The effect lasts up to one month, but is not maintained at six months follow-up. MA probably does not improve pain or physical functioning. Acupuncture appears safe. People with fibromyalgia may consider using EA alone or with exercise and medication. The

    Different lesions may affect the liver resulting in harmful stimuli. Some therapeutic procedures to treat those injuries depend on liver regeneration to increase functional capacity of this organ. Evaluate the effects of tranexamic acid on liver regeneration after partial hepatectomy in rats. 40 rats (Rattus norvegicus albinus, Rodentia mammalia) of Wistar-UP lineage were randomly divided into two groups named control (CT) and tranexamic acid (ATX), with 20 rats in each. Both groups were subdivided, according to liver regeneration time of 32 h or seven days after the rats had been operated. The organ regeneration was evaluated through weight and histology, stained with HE and PCNA. The average animal weight of ATX and CT 7 days groups before surgery were 411.2 g and 432.7 g, and 371.3 g and 392.9 g after the regeneration time, respectively. The average number of mitotic cells stained with HE for the ATX and CT 7 days groups were 33.7 and 32.6 mitosis, and 14.5 and 14.9 for the ATX and CT 32 h groups, respectively. When stained with proliferating cell nuclear antigen, the numbers of mitotic cells counted were 849.7 for the ATX 7 days, 301.8 for the CT 7 days groups, 814.2 for the ATX 32 hand 848.1 for the CT 32 h groups. Tranexamic acid was effective in liver regeneration, but in longer period after partial hepatectomy. Muitas são as injúrias que acometem o fígado e levam a estímulo lesivo. Alguns procedimentos terapêuticos para tratamento dessas lesões dependem da regeneração hepática para aumentar a sua capacidade funcional.

    Full Text Available Objectives: The purpose of this study is to report a case of a plexiform neurofibroma (PNF in the pelvic region treated with sweet bee venom (SBV and mountain ginseng pharmacopuncture (MGP. Methods: A 16-year-old girl was diagnosed as having PNFs, neurofibromatosis type 1, 10 years ago and she had surgery three times to remove the benign tumors, but the growth of the PNFs continued. She has been treated in our clinic with SBV and MGP two times per month from March 2010 to April 2014. SBV was injected intra-subcutaneously at the borders of the PNFs in the pelvic region, and MGP was administrated intravenously each treatment time. Results: The growths of the PNFs occurred rapidly and continued steadily before treatment. Since March 2010, she has been treated in our clinic, and the growths of the PNFs have almost stopped; further-more, the discomfort of hip joint pain has been reduced, and her general condition has improved. Conclusion: We cautiously conclude that SBV and MGP treatment has some effects that suppress the growth and the spread of the PNFs in this patient.

    2018-01-01

    The treat-to-target (T2T) approach has been successfully implemented in a number of diseases. T2T has been proposed for rheumatic diseases such as RA, spondyloarthritis, lupus, and recently for gout. The level of evidence for such approaches differs from one condition to the other (moderate to high for hyperlipidaemia, for example). Practice is based on the best available evidence at any time, and in absence of good evidence for T2T in gout, some suggest a conservative only-treat-symptoms approach. Evidence suggests that not treating gout to target in the long term is overall associated with worsening outcomes, such as flares, tophi and structural damage, which is associated to loss of quality of life and mortality. Different targets have been proposed for hyperuricaemia in gout; lower than 6 mg/dl (0.36 mmol/l) for all patients, at least gout. © The Author 2018.

    Urinary tract infections (UTI) in pregnant women are a relatively frequent occurrence and the spectrum of these infections ranges from lower urinary tract disease (asymptomatic bacteriuria, acute cystitis) to upper urinary tract disease (acute pyelonephritis). Anatomical and functional changes in the urinary tract in pregnancy result in significantly higher susceptibility to progression of the infection from asymptomatic bacteriuria to the stage of acute pyelonephritis. Untreated asymptomatic bacteriuria in pregnancy leads, in as much as 40%, to the development of acute pyelonephritis with all the subsequent negative effects not only for the woman herself, but particularly for the fetus. Bacteriuria in pregnancy accounts for a significantly higher number of newborns with a low birth weight, low gestational age and higher neonatal mortality rate. Therefore, it is necessary to perform screening for bacteriuria in pregnant women and, when the finding is positive, to treat this bacteriuria. The selection of an appropriate antimicrobial agent to treat urinary tract infection in pregnancy is limited by the safety of a given drug not only for the woman, but particularly for the fetus. The article provides an overview of medications that can be safely used throughout the pregnancy or only in certain stages of pregnancy. The selection of an appropriate antibiotic should always be preceded by the result of urine culture. The article presents the principles and rules for treating asymptomatic bacteriuria, acute cystitis and acute pyelonephritis in pregnant women.

    The TREAT reactor was built as a transient irradiation test reactor. By taking advantage of built-in system features, it was possible to add a neutron-radiography facility. This facility has been used over the years to radiograph a wide variety and large number of preirradiated fuel pins in many different configurations. Eight different specimen handling casks weighing up to 54.4 t (60 T) can be accommodated. Thermal, epithermal, and track-etch radiographs have been taken. Neutron-radiography service can be provided for specimens from other reactor facilities, and the capacity for storing preirradiated specimens also exists

  2. Process of treating carbonaceous substances

    Energy Technology Data Exchange (ETDEWEB)

    1938-12-16

    A process is described of removing halogens or halogen compounds (or both) from the products which form when carbonaceous substances are treated thermally in the presence of halogens or halogen compounds, consisting of passing the reaction products at the same temperature with a substance able to fix halogens or acid halides through an apparatus included between the receiver and the heat exchanger, which contains, in a relatively restricted space, internal elements obliquely disposed in relation to the direction of the flow, stretched in this direction and constituted preferably of helicoidal passages.

  3. Treating Intraradicular Pockets of molars

    1987-10-01

    Full Text Available It appears that until bone graft has not achieved 100% success, intraradicular diseases remain controversial and therefore, different treatment plans are suggested for them. Treating intraradicular diseases depend on many factors: maxillary molars are more prone to bone loss and have worse prognosis. To assess prognosis more carefully these factors should be considered: 1 bone loss: its apical depth, local or generalized 2 bone condition: buccal, lingual, mesial and distal aspects 3 tooth mobility: grades 2 and 3 have not good prognosis. Crown root ratio is also important. 4 the angle of divergence of roots: the more the roots are divergent, the better the prognosis would be. 5adjacent teeth health 6tooth position in jaws 7 age and general health of the patients 8 oral hygiene In general, teeth with 2 roots can be treated more effectively than 3 root ones. Maxillary first premolars are exceptions that do not respond to the treatments positively. We should look forward to the future investigations and findings.

  4. Treating leachate by Fenton oxidation

    Full Text Available Leachates are formed from liquids, mainly rainwater, percolating through solid wastes during stabilisation. Their composition is variable and highly toxic; leachate treatment is therefore a complex task. Leachates represent a high risk to health due to the Yucatan Peninsula’s highly permeable soil. The results are presented from applying the Fenton process to treating leachate from the sanitary Merida landfill, Yucatan, Mexico. The Fenton process consists of treating the contaminant load with an H2O2 and FeSO4 combination in acidic conditions. Optimal reaction time, pH value, Fenton reagent dose, post treatment coagulation – flocculation doses and increased biodegradability index were all determined. Optimal oxidation conditions and doses were 202+ minute contact time, 4 pH, 600 mg/L H2O2 concentration and 1,000 mg/L Fe. Average organic matter removal rate, measured as CODS and TOC, were 78% and 87% respectively. The biodegradability index increased from 0.07 to 0.11 during the Fenton process and up to 0.13 when the Fenton process was followed by coagulation-flocculation.

  5. Quantum leap for treating wastewaters

    Full text: For many Australian food manufacturers there is increasing pressure from government agencies to reach higher standards of wastewater treatment for environmental discharge. In fact, throughout the western wolrd industrual water users are facing a similar challenge. One of the big problems is ageing pipe networks, particularly sewage pipes. Also, industrial wastewaters with high sugar-nutrient loads can cause serious damage to pipelines. This is because fermentation occurs within the wastewater, eroding and degrading the pipes, causing numerous cracks and fractures. This in turn leads to water ingress, which puts a strain on treatment plants because of the higher volume of water, especially in wet weather. Food manufacturing produces large volumes of mostly biodegradable liquid and solid waste. Wastewaters released from food manufacturing can be 'muddy', with high concentrations of suspended solids, fats, oils and grease (FOGs), and, usually, nutrients such as nitrogen. The issue for many food manufacturers is that existing wastewater treatment systems are unable to reduce the nutrient load in the biological treatment stage to a level allowing acceptable discharge. In addition, most rely on large tanks housing bacteria that are submerged in water and aerated. Aeration is energy-hungry and can create a 'sludge-cake' on top of the water, which is difficult to treat. Most existing technologies also use filters, but they foul easily and require ongoing maintenance. According to BioGill chief executive John West, the BioGill technology is groundbreaking and radically different from conventional bioreactors because the 'gills' are not submerged. Instead, the gills, composed of Nano-Ceramic Membrane sheets arranged vertically in pairs, are suspended in the air, above ground, with wastewater travelling down between them. “Fungi and bacteria, known as biomass, grow on the membranes in direct contact with the air, eating nutrients much faster than other systems

    Malnutrition is a clinical and public health problem. It has adverse effects on the physical and psycho-social wellbeing of individuals by predisposing to disease, negatively affecting its outcome and reducing the likelihood of independence. An estimated 3 million people in the UK are affected by malnutrition, most of whom live in the community ( BAPEN, 2011 ). Despite the scale of this problem, it remains under-detected, under-treated, underresourced and often overlooked by those involved in the care of at risks individuals such as the elderly. In most cases malnutrition is a treatable condition that can be managed by optimising food intake and using oral nutritional supplements (ONS) where necessary. The main focus of this article is on the dangers of malnutrition for older people in the community and the use of ONS in the treatment and management of malnutrition.

    Orgasmic headache (OH) is a sudden and severe headache that occurs at the time of or shortly after an orgasm. AIM.: We present the case of typical primary headache associated with sexual activity, especially during an orgasmic period. A 34-year-old man complained of sudden and severe headache during sexual activity, or orgasmic period, for 2 months. The headache developed abruptly with an orgasm and then decreased shortly over a period of 4 ≈ 8 hours. Magnetic resonance angiography revealed severe spasm of the M1 segment of both the middle cerebral arteries. He was treated with oral nimodipine (30 mg every 8 hours), which alleviated the headache and prevented its recurrence. We postulated a pathophysiological relationship between OH and migraine, especially with respect to vasoconstriction, and believe that in such cases, nimodipine may be an effective therapy. © 2013 International Society for Sexual Medicine.

  9. Process for treating hydrocarbons, etc

    Energy Technology Data Exchange (ETDEWEB)

    1933-09-15

    A process is described for treating simultaneously bituminous substances and hydrocarbon oils for the production of low-boiling hydrocarbons and volatilization of the bituminous substances, characterized by the fact that it consists of heating a current of charge constituted by a mixture of the bituminous substances and hydrocarbon oils, to a high temperature, passing the heated current into a zone of extended reaction where the vapors are separated from the liquid or solid residue to favor transformation of the liquid hydrocarbons and volatilization of the bituminous substances, owing to the utilization of a heating agent carried to a high temperature being brought in contact with the heated charge in order to communicate its heat to the charge, while this later presents itself as relatively fine pellet or in the condition of distinct particles, particularly separated from one another.

    Full Text Available Glycerine treated nanofibrillated cellulose (GNFC was prepared by mixing aqueous nanofibrillated cellulose (NFC suspensions with glycerine. Styrene maleic anhydride (SMA copolymer composites with different loadings of GNFC were prepared by melt compounding followed by injection molding. The incorporation of GNFC increased tensile and flexural modulus of elasticity of the composites. Thermogravimetric analysis showed that as GNFC loading increased, the thermal stability of the composites decreased marginally. The incorporation of GNFC into the SMA copolymer matrix resulted in higher elastic modulus (G′ and shear viscosities than the neat SMA copolymer, especially at low frequencies. The orientation of rigid GNFC particles in the composites induced a strong shear thinning behavior with an increase in GNFC loading. The decrease in the slope of elastic modulus with increasing GNFC loading suggested that the microstructural changes of the polymer matrix can be attributed to the incorporation of GNFC. Scanning electron microscopy (SEM images of fracture surfaces show areas of GNFC agglomerates in the SMA matrix.

  11. Process for treating oil shale

    Energy Technology Data Exchange (ETDEWEB)

    1920-08-22

    A process for treating oil shale is characterized in that the shale is first finely ground, then heated in the presence of steam in a high-pressure retort at 1 to 50 atmospheres pressure at a temperature of 200/sup 0/ to 450/sup 0/C and then with large amounts of water with or without materials forming emulsions with water or with oil. Solution medium suitable for bitumen or paraffin is beaten up in a rapid hammer mill until all or most all of the oil or bitumen is emulsified. The emulsion is separated by filter-pressing and centrifuging from the solid shale residue and the oil or bitumen is again separated from the emulsion medium by heating, acidulating, standing, or centrifuging, and then in known ways is further separated, refined, and worked up.

  12. To treat or not to treat: should psychologists treat tobacco use disorder?

    Bodie, Linda P

    2014-08-01

    The author presented this Presidential Address for Divison 18, Psychologists in Public Service, at the 2012 American Psychological Association Convention in Orlando, Florida. The address challenges public service psychologists to reduce the tobacco disease burden through their roles as researchers, leaders, educators, and practitioners and explains why treating tobacco use disorder is important and relevant for psychologists. The address discusses the prevalence and the resulting mortality and morbidity rates of tobacco use disorder, which call for effective evidence-based interventions that can be integrated by psychologists into other ongoing treatments. Treatment of the underserved populations, including those with serious mental illness and/or substance use disorders, presents many barriers. In addition, education and training for tobacco use disorder in undergraduate and graduate clinical psychology programs present further barriers for psychology trainees. However, progress is being made because of the numerous resources and psychology leaders who are advocates for tobacco use disorder treatment and research. Challenges for the future include increasing awareness of the importance of treatment for tobacco use disorder, finding innovative ways to increase access to comprehensive evidence-based treatment, and acknowledging that psychologists can make a difference in reducing the tobacco use disorder disease burden. Psychologists have an ethical and professional responsibility to treat tobacco use disorder.

    Background Cholera is an acute watery diarrhoea caused by infection with the bacterium Vibrio cholerae, which if severe can cause rapid dehydration and death. Effective management requires early diagnosis and rehydration using oral rehydration salts or intravenous fluids. In this review, we evaluate the additional benefits of treating cholera with antimicrobial drugs. Objectives To quantify the benefit of antimicrobial treatment for patients with cholera, and determine whether there are differences between classes of antimicrobials or dosing schedules. Search methods We searched the Cochrane Infectious Disease Group Specialized Register; the Cochrane Central Register of Controlled Trials (CENTRAL); PubMed; EMBASE; African Index Medicus; LILACS; Science Citation Index; metaRegister of Controlled Trials; WHO International Clinical Trials Registry Platform; conference proceedings; and reference lists to March 2014. Selection criteria Randomized and quasi-randomized controlled clinical trials in adults and children with cholera that compared: 1) any antimicrobial treatment with placebo or no treatment; 2) different antimicrobials head-to-head; or 3) different dosing schedules or different durations of treatment with the same antimicrobial. Data collection and analysis Two reviewers independently applied inclusion and exclusion criteria, and extracted data from included trials. Diarrhoea duration and stool volume were defined as primary outcomes. We calculated mean difference (MD) or ratio of means (ROM) for continuous outcomes, with 95% confidence intervals (CI), and pooled data using a random-effects meta-analysis. The quality of evidence was assessed using the GRADE approach. Main results Thirty-nine trials were included in this review with 4623 participants. Antimicrobials versus placebo or no treatment Overall, antimicrobial therapy shortened the mean duration of diarrhoea by about a day and a half compared to placebo or no treatment (MD -36.77 hours, 95% CI -43

    1991-01-01

    A process of treating water to remove transuranic elements contained therein by adjusting the pH of a transuranic element-containing water source to within the range of about 6.5 to about 14.0, admixing the water source with an alkali or alkaline earth ferrate in an amount sufficient to form a precipitate within the water source, the amount of ferrate effective to reduce the transuranic element concentration in the water source, permitting the precipitate in the admixture to separate and thereby yield a supernatant liquid having a reduced transuranic element concentration, and separating the supernatant liquid having the reduced transuranic element concentration from the admixture is provided. Additionally, a water soluble salt, e.g., a zirconium salt, can be added with the alkali or alkaline earth ferrate in the process to provide greater removal efficiencies. A composition of matter including an alkali or alkaline earth ferrate and a water soluble salt, e.g., a zirconium salt, is also provided.

  19. Treating water-reactive wastes

    International Nuclear Information System (INIS)

    Lussiez, G.W.

    1993-01-01

    Some compounds and elements, such as lithium hydride, magnesium, sodium, and calcium react violently with water to generate much heat and produce hydrogen. The hydrogen can ignite or even form an explosive mixture with air. Other metals may react rapidly only if they are finely divided. Some of the waste produced at Los Alamos National Laboratory includes these metals that are contaminated with radioactivity. By far the greatest volume of water-reactive waste is lithium hydride contaminated with depleted uranium. Reactivity of the water-reactive wastes is neutralized with an atmosphere of humid nitrogen, which prevents the formation of an explosive mixture of hydrogen and air. When we adjust the temperature of the nitrogen and the humidifier, the nitrogen can be more or less humid, and the rate of reaction can be adjusted and controlled. Los Alamos has investigated the rates of reaction of lithium hydride as a function of the temperature and humidity, and, as anticipated, they in with in temperature and humidity. Los Alamos will investigate other variables. For example, the nitrogen flow will be optimized to conserve nitrogen and yet keep the reaction rates high. Reaction rates will be determined for various forms of lithium waste, from small chips to powder. Bench work will lead to the design of a skid-mounted process for treating wastes. Other water-reactive wastes will also be investigated

    Full Text Available Undoubtedly, no regular practice of physical exercise is one of thefactors that determine the global epidemics of weight excess andobesity in all age groups. Taking up physical activities regularlysince the initial stages of life (childhood, during adolescence andmaintaining them in adulthood – from young adults to over 50 yearsof age - is essential to assure an appropriate control of weight andbody fat. The general recommendation of physical exercise for goodhealth is to practice at least 30 minutes of moderate activities, atleast five days a week, and preferably every day. When the purposeis to lose and control weight in overweighed and obese individuals,the minimum practice should last 60 minutes/day, preferably 90minutes/day, at least five days/week, in a continuous or accumulatedmanner. Physical exercise is associated with several physical,psychological and social benefits that justify it inclusion as a crucialstrategy to prevent and treat overweight and obesity in any agegroup. Apart from moderate aerobic physical exercise, such aswalking, cycling, swimming, or more vigorous activities, such asjogging or running, resistance exercises and changes in lifestyle areessential, together with re-education of eating habits, to fight theepidemics of overweight and obesity. Besides the effect of weightcontrol, reduced body fat, prevention of weight gain and maintenanceof lean mass, physical exercise is related to a better lipid profile andreduced risk of associated diseases, such as diabetes, hypertension,metabolic syndrome, cardiovascular diseases and, consequently,lower risk of death.

    Therapeutic management in inflammatory bowel diseases (IBD) has significantly changed in the last decades with the advent of biological therapy resulting in new treatment targets other than clinical symptoms. Patient stratification in the early stage of the disease is an important step to identify patients with poor prognosis, who might benefit from early aggressive treatment to avoid complications in the later disease course. Recent randomized and hypothesis driven (e.g., Randomized Evaluation of an Algorithm for Crohn's Treatment, Post-Operative Crohn's Endoscopic Recurrence) clinical trials conducted in the biological era underscore the need of objective disease monitoring including assessment of biomarkers (e.g., C-reactive protein and calprotectin), mucosal healing and, for biologically treated patients, therapeutic drug monitoring beside clinical symptom assessment in both Crohn's disease and ulcerative colitis. Assessing the treatment efficacy objectively has become an important element of patient monitoring besides clinical symptom assessment. Further clinical studies are needed to assess whether implementation of new therapeutic algorithms based on these targets and tight monitoring in clinical practice have the potential to further improve long-term disease outcomes in IBD. © 2016 S.

    The effects of X radiation on the structure of the parotid glands of young rats are studied by means of morphologic technique. Seventy male rats (Rattus norvegicus, albinus Holtzman) were distributed in two experimental groups: Group 1- irradiated and Group 2- control. The region of the parroted glands was irradiated with a dose of 300 rads from 48 to 48 hours up to an exposition of 1.200 rads. After predetermined periods the animals belonging to both groups were sacrificed and the parotid glands were removed for histopathologic evaluation. The serous acini showed to be radium sensitive and in the periods closer to the radiation, the glandular structure des organization and degeneration was noted. (M.A.C.)

    1989-01-01

    The purpose of this study is to assess the current status of in-vivo use of monoclonal antibodies for treating cancer. Publications appearing between 1980 and 1988 were identified by computer searches using MEDLINE and CANCERLIT, by reviewing the table of contents of recently published journals, and by searching bibliographies of identified books and articles. More than 700 articles, including peer-reviewed articles and book chapters, were identified and selected for analysis. The literature was reviewed and 235 articles were selected as relevant and representative of the current issues and future applications for in-vivo monoclonal antibodies for cancer therapy and of the toxicity and efficacy which has been associated with clinical trials. Approaches include using antibody alone (interacting with complement or effector cells or binding directly with certain cell receptors) and immunoconjugates (antibody coupled to radioisotopes, drugs, toxins, or other biologicals). Most experience has been with murine antibodies. Trials of antibody alone and radiolabeled antibodies have confirmed the feasibility of this approach and the in-vivo trafficking of antibodies to tumor cells. However, tumor cell heterogeneity, lack of cytotoxicity, and the development of human antimouse antibodies have limited clinical efficacy. Although the immunoconjugates are very promising, heterogeneity and the antimouse immune response have hampered this approach as has the additional challenge of chemically or genetically coupling antibody to cytotoxic agents. As a therapeutic modality, monoclonal antibodies are still promising but their general use will be delayed for several years. New approaches using human antibodies and reducing the human antiglobulin response should facilitate treatment. 235 references

    Schistosomiasis is a parasite that is carried by freshwater snails. The intestinal form infects the intestine, liver and spleen and can be fatal. The objective of this review was to assess the effects of oxamniquine or praziquantel for treating Schistosomiasis mansoni We searched the Cochrane Infectious Diseases Group trials register, the Cochrane Controlled Trials Register, Medline, Lilacs and reference lists of articles. The Revista da Sociedade Brasileira de Medicina Tropical and Brazilian Tropical Medicine Congress abstracts were handsearched Randomised and quasi-randomised trials comparing oxamniquine and/or praziquantel to placebo for the treatment of Schistosomiasis mansoni. Two reviewers independently assessed trial quality and extracted data. Thirteen trials met the inclusion criteria. Praziquantel and oxamniquine were effective in curing Schistosoma mansoni infection when compared to placebo. In Africa, praziquantel 40 mg/Kg is more effective than oxamniquine 15 mg/Kg in individuals older than 14 years (OR 3.54, 95%CI 1.70, 7.38), but no difference was found when compared with oxamniquine 30 mg/Kg (OR 0.29, 95%CI 0.08, 1.01). In Brazil, praziquantel was equally effective when compared with oxamniquine in individuals older than 14 years (OR 1.70, 95%CI 0.83, 3.49). Both drugs appear safe. There was no difference in reinfection rate between zinc supplementation and placebo (OR 0.82, 95%CI 0.47, 1.41). IPraziquantel and oxamniquine both appear to be effective for the treatment of Schistosomiasis mansoni, although lower doses of oxamniquine (less than 30 milligrams per kilogram) may not be as effective.

    1993-01-01

    During field trials in the North Sea in 1992, three 20-tonne slicks of a relatively weak 30% water-in-oil emulsion were released. Two of the slicks were treated with demulsifier from spray aircraft and one of the treated slicks was sprayed with dispersant seven hours later. The experiment used flow-through fluorometry to determine oil concentrations below the control and demulsifier-treated slick. Remote sensing imagery was used to determine the area of the surface slicks. Emulsion formation was slowed down in the two demulsifier-treated slicks relative to the control slick. The demulsifier-treated slicks resulted in maximum oil concentrations in water some five times higher than the control slick and spread over a volume 10-20 times as large. The control slick was therefore more persistent on the sea surface than either of the treated slicks. 5 refs., 5 figs., 5 tabs

    The options for treating heart disease have greatly expanded during the course of the last 2 1/2 decades with the advent of hybrid technology. The hybrid option for treating cardiac disease implies using the technology of both interventional cardiology and cardiac surgery to treat cardiac disease. This rapidly developing technology has given rise to new and creative techniques to treat cardiac disease involving coronary artery disease, coronary artery disease and cardiac valve disease, and atrial fibrillation. It has also led to the establishment of new procedural suites called hybrid operating rooms that facilitate the integration of technologies of interventional cardiology catheterization laboratories with those of cardiac surgery operating rooms. The development of hybrid options for treating cardiac disease has also greatly augmented teamwork and collaboration between interventional cardiologists and cardiac surgeons.

    With the deferral of the Safety Test Facility (STF), the TREAT Upgrade (TU) reactor has assumed a lead role in the US LMFBR safety test program for the foreseeable future. The functional requirements on TU require a significant enhancement of the capability of the current TREAT reactor. A design of the TU reactor has been developed that modifies the central 11 x 11 fuel assembly array of the TREAT reactor such as to provide the increased source of hard spectrum neutrons necessary to meet the functional requirements. A safety consequence of the increased demands on TU is that the self limiting operation capability of TREAT has proved unattainable, and reliance on a safety grade Plant Protection System is necessary to ensure that no clad damage occurs under postulated low-probability reactivity accidents. With that constraint, the physics design of TU provides a means of meeting the functional requirements with a high degree of confidence

    Jaundice is regarded as a mysterious disease rather than a symptom of disease in several parts of India. We describe 8 cases that underwent branding to treat jaundice and subsequently presented to our centre. The causes for jaundice in these patients included a variety of benign and malignant disorders. Our report suggests that despite being literate, strong cultural beliefs lead people to seek potentially harmful procedures like branding to treat jaundice in parts of India.

    The effect of under treatment with adjuvant hormonal therapy, chemotherapy, or radiation was studied in elderly women with breast cancer. A prospectively maintained database was used to identify women undergoing potentially curative surgery between 1978 and 2012. The presentation, pathologic findings, treatment, and outcomes of 382 women over 70 were compared to the findings in 2065 younger patients. Subsequently, conventionally treated and under treated elderly patients were identified and their characteristics and outcomes were compared. Both young and old patients presented most frequently with mammographic findings, but older patients presented more frequently with mammographic masses while younger patients presented more frequently with mammographic calcifications. Cancers of older patients were significantly more favorable than cancers in younger patients: smaller, with more infiltrating lobular, fewer ductal carcinoma in situ, and more frequently estrogen receptor positive and fewer were poorly differentiated. Elderly patients had less axillary sampling, fewer mastectomies, less adjuvant radiation therapy, and more hormonal therapy. Fifty-one percent of the 382 elderly patients were under treated by conventional criteria. Under treated patients were more frequently in situ, better differentiated, smaller, and more often estrogen receptor positive. Forty-four percent of the under treated patients died during followup without disease recurrence. Despite under treatment, local and distant disease-free survival was comparable to patients who were not under treated.

  6. Phylogeography of Rattus norvegicus in the South Atlantic Ocean

    2016-12-01

    Full Text Available Norway rats are a globally distributed invasive species, which have colonized many islands around the world, including in the South Atlantic Ocean. We investigated the phylogeography of Norway rats across the South Atlantic Ocean and bordering continental countries. We identified haplotypes from 517 bp of the hypervariable region I of the mitochondrial D-loop and constructed a Bayesian consensus tree and median-joining network incorporating all other publicly available haplotypes via an alignment of 364 bp. Three Norway rat haplotypes are present across the islands of the South Atlantic Ocean, including multiple haplotypes separated by geographic barriers within island groups. All three haplotypes have been previously recorded from European countries. Our results support the hypothesis of rapid Norway rat colonization of South Atlantic Ocean islands by sea-faring European nations from multiple European ports of origin. This seems to have been the predominant pathway for repeated Norway rat invasions of islands, even within the same archipelago, rather than within-island dispersal across geographic barriers.

    1997-01-01

    A case history of a 'pump and treat' system, designed to remediate chlorinated solvents and petroleum hydrocarbons in soil and groundwater resulting from historic leaking of six underground storage tanks, was described. The objective of this paper was two-fold: (1) to call into question the findings of some earlier studies which claimed that 'pump and treat' will not work to remediate impacted groundwater in a timely or cost-effective manner, and (2) to demonstrate that under certain circumstances, at some sites, groundwater 'pump and treat' may be the most appropriate, lowest cost remediation alternative. The paper also demonstrates the applicability of horizontal wells and methods to use soil venting in the saturated zone as opposed to its traditional use in the vadose zone. Details of the design parameters, system characteristics and operation are provided. 2 refs., 2 tabs

    A field experiment was carried out in Northern Italy (Po Valley), within the frame of the EU project SAFIR, to asses the impact of treated wastewater reuse on potato yield, quality and hygiene. The potato crop was drip irrigated and fertigated. Wastewater produced by small communities (≤2000 EI......) was treated by Membrane Bio Reactor (MBR) technology and gravel filter (FTS) during three cropping seasons. Treated wastewater, soil and tubers were analysed for the faecal indicator bacterium E. coli and heavy metals contents. Potato total yield was similar for tap and reused water, while the marketable...... production has been found higher with the latter. The tuber dry matter content as well as reducing sugars were not affected by reused water. Total sugars content was higher with MBR and FTS water. Water use efficiency (WUE) was significantly higher with reused water. Compared to tap water, crop gross margin...

    1975-01-01

    The development of fuel motion monitoring is traced from its inception through present operation and into future programs. After noting the role of fuel motion studies in terms of safety assurance for the LMFBR, the history of in-pile fuel monitoring is reviewed. The operational record of the present TREAT fast neutron hodoscope is summarized with attention to various performance features. Development plans for the TREAT hodoscope are described in some detail. Application of the hodoscope has been considered for eight safety facilities other than TREAT. In addition, there is a possible role for fuel monitoring techniques to be extended to real-time ex-vessel core surveillance in operating reactors. Certain intrinsic strengths of the hodoscope technique for material monitoring are identified. The pattern of development may be characterized as an adaptation of several technologies to fit available requirements and resources

    Objective: To assess the clinical effects of uterine arterial embolization on uterine leiomyoma. Methods: The authors treated 21 patients with uterine leiomyoma by Seldinger's uterine arterial embolization. The 4.0 F Cobra catheter was laced into the double uterine arteries with Polyvinyl Alcohol Foam (PVA) particles as the embolization. At 3 and 6 months postoperatively, the authors investigated the effects of the embolization. Results: After uterine arterial embolization, the volume of uterine leiomyoma decreased and menorrhagia was under controlled. The symptoms of anemia and oppression were relieved. The physiologic functions of ovary and uterus were preserved completely. Conclusions: Uterine arterial embolization is an effective and less invasive way to treat uterine leiomyoma

    Psychotherapy with same-sex couples does not differ markedly from standard couple therapies; this is also true for treating couples facing infidelity. However, same-sex couples often design their relationships differently, without tradition and formal marital contracts to prescribe behavior. Based on clinical experience and the empirical research, this article addresses the differing norms involved in affirmatively treating infidelity in gay and lesbian couples within the framework of integrative behavioral couple therapy (IBCT). Two cases illustrate the process and outcome of IBCT with same-sex couples.

    Somatic symptom disorder (SSD) is a challenging condition to treat with chronic pain, a common and disabling symptom. We present a patient who received electroconvulsive therapy (ECT) for SSD with significant improvement in pain and gastrointestinal symptoms. We also present a brief literature review of similar cases treated with ECT. Preliminary evidence suggests that ECT should be considered for treatment of SSD comorbid with major depressive disorder, when standard treatments fail. Further research is needed to clarify whether ECT can be used for SSD without associated depression.

To analyze the biomechanical parameters of colonic suture in rats undergoing colectomy, using sugarcane molasses polysaccharide as tape or gel. 45 Wistar rats (Rattus norvegicus albinus) were randomized into three groups of 15 animals: irrigation of enteric sutures with 0.9% saline solution; application of sugarcane molasses polysaccharide as tape; and sugarcane molasses polysaccharide as gel. The rats underwent colon ressection, with subsequent reanastomosis using polypropylene suture; they were treated according to their respective groups. Five rats from each group were evaluated at different times after the procedure: 30, 90 and 180 days postoperatively. The following variables were evaluated: maximum rupture force, modulus of elasticity and specific deformation of maximum force. The biomechanical variables among the scheduled times and treatment groups were statistically calculated. The characteristics of maximum rupture force and modulus of elasticity of the specimens remained identical, regardless of treatment with saline, polysaccharide gel or tape, and treatment time. However, it was found that the specific deformation of maximum force of the intestinal wall was higher after 180 days in the group treated with sugarcane polysaccharide gel (p=0.09). Compared to control, it was detected greater elasticity of the intestinal wall in mice treated with sugarcane polysaccharide gel, without changing other biomechanical characteristics, regardless of type or time of treatment. A aplicação de produtos em anastomoses colônicas que possam prevenir o surgimento de deiscências são de grande interesse médico.

    Bioengineering strategies have demonstrated enormous potential to treat female infertility as a result of chemotherapy, uterine injuries, fallopian tube occlusion, massive intrauterine adhesions, congenital uterine malformations, and hysterectomy. These strategies can be classified into two broad categories as follows: (i) Transplantation of fresh or cryopreserved organs into the host and (ii) tissue engineering approaches that utilize a combination of cells, growth factors, and biomaterials that leverages the body's inherent ability to regenerate/repair reproductive organs. While whole organ transplant has demonstrated success, the source of the organ and the immunogenic effects of allografts remain challenging. Even though tissue engineering strategies can avoid these issues, their feasibilities of creating whole organ constructs are yet to be demonstrated. In this article we summarize the recent advancements in the applications of bioengineering to treat female infertility.

    This article addresses clinical and ethical directions in treating clients coping with infidelity. Developing competence in this domain requires familiarity with empirical research regarding infidelity, individual and cultural differences involving non-monogamy, and assessment and intervention skills related to treating infidelity. Practical directions will entail distinguishing among responsibilities to individual partners versus their relationship and managing related potential conflicts of interest with other involved parties. Confidentiality assumes increased complexity when confronting undisclosed infidelity in couple therapy and when a client engaging in high-risk behaviors for contracting STDs or testing seropositive for HIV has not informed his or her partner(s). Finally, we discuss therapists' need to concretely articulate their values that influence treatment of infidelity.

    Osteoporosis is a chronic disease, carrying an elevated risk of fractures, morbidity, and death. Long-term treatment may be required, but the long-term risks with osteoporosis drugs remain incompletely understood. The competing risk of death may be a barrier to treating the oldest, yet this may...... not be rational if the risk of death is reduced by treatment. It is difficult to devise goal-directed long-term strategies for managing osteoporosis without firm information about residual life expectancy in treated patients.

    Full Text Available Restoration of endodontically treated teeth is important for the success of endodontic treatment. In full coverage restorations, maximum amount of tooth structure is compromised, so as to conserve the amount of tooth structure partial coverage restorations, can be preferred. This case report is on fabrication of a conservative tooth colored restoration for an endodontically treated posterior tooth. A 22-year-old male patient presented with pain in the mandibular left first molar. After endodontic treatment, composite material was used as postendodontic restoration. The tooth was then prepared to receive a ceramic onlay and bonded with self-adhesive universal resin cement. Ceramic onlay restoration was periodically examined up to 2 years.

    Children ranging from 3 to 5 years were introduced to two anthropomorphic robots that provided them with information about unfamiliar animals. Children treated the robots as interlocutors. They supplied information to the robots and retained what the robots told them. Children also treated the robots as informants from whom they could seek information. Consistent with studies of children's early sensitivity to an interlocutor's non-verbal signals, children were especially attentive and receptive to whichever robot displayed the greater non-verbal contingency. Such selective information seeking is consistent with recent findings showing that although young children learn from others, they are selective with respect to the informants that they question or endorse.

    Full Text Available Lead, a ubiquitous metal, is one of the most abundant elements present on earth. Its easy availability and cost effectiveness made it an extremely popular component in the industrial revolution. However, its hazardous health effects were not considered at the time. Over the last few decades, with the adverse effects of lead coming to the forefront, nations across the world have started to recognize and treat lead toxicity. The most reliable and used method until now has been chelation therapy. Recent research has suggested the use of natural products and sources to treat lead poisoning with minimal or no side effects. This review has tried to summarize a few of the natural products/sources being investigated by various groups.

    Results: Metoprolol, an antagonist, significantly decreased the thermal latency and mechanical thresholds with dose and time dependent manner. However, dobutamine, an agonist, enhanced the latency and thresholds dose and time dependent. Conclusions: This results suggest that in contrast to dobutamine, locally treated metoprolol may cause hyperalgesic and allodynic actions. In addition, our results can demonstrate that peripheral beta-adrenergic receptors can play important roles in nociceptive process. [Cukurova Med J 2015; 40(2.000: 258-266

    Percutaneous nephrolithotripsy (PNL) is the recommended method of surgical treatment of kidney stones of size greater than 2 cm. Trends in the development of modern urology have been steadily toward less traumatic method to treat nephrolithiasis - minimally invasive PNL. The present work aimed to explore of the possibilities of one of the modern variants of minimally invasive PNL - ultra-mini-PNL in treating nephrolithiasis. The study included 60 patients (mean age 45.6+/-7.2 years) with isolated kidney calculus, up to 2.0 cm or several stones with a total size of up to 2.5 cm. All patients were found to have 77 kidney stones, six of which had a size of 10 mm, 51 had a size of 11-15 mm and 20 had a size of 16-20 mm. 45% of patients had isolated renal pelvic stones and 28.3% had stones in the renal pelvis and lower calyx. All patients underwent ultra-mini-PNL using nephroscope size 7.5 Ch and tube size 12 Fr. The average duration of surgery from the moment of the puncture of the pyelocaliceal system to installing the nephrostomy tube was 65.4 minutes. Complete clearance of stones after single-stage ultra-mini-PNL was observed in 80% of cases. Nephrostomy tube was removed on days 2-3. The average postoperative hospital stay was 5.1 days. The most common complication was postoperative exacerbation of pyelonephritis (13.3% of patients), successfully treated with conservative measures. There were no cases of postoperative bleeding, accompanied by anemia and needed a blood transfusion. Considering high effectiveness and low rate of complications of ultra-mini-PNL, it can be successfully used in treating nephrolithiasis among a wide group of patients.

    Treating dermatosis with liquid nitrogen as cryogen (substance generating cold) allows cellular destruction in more than 5 mm depth, making it indispensable to use it treating cutaneous cancers; besides that, it is cheap, easy to conserve and manage, and it is not considered flammable or toxic. Its applying retains the growth factor inside the injury, the collagen is not damaged as it is in burning by hot, there is not almost injury contraction, the perineurium is not altered, and when the tissue necrosis takes place, it retains tissue necrosis factor, helping to increase the necrosis of tissues. Taking into account the high incidence of dermatosis that can be treated with cryogen, in our consultation; we decided to generalize this treatment at the Provincial Interior Ministry Clinic. Plantar warts represent a big percent, limiting our patients in developing their working activities. This cutaneous viral disease is favored by the patients' systemic immunodepressions, hyperhidrosis and podalic disturbances. We selected the patients assisting to our extern al consultation with plantar wart clinical diagnosis in the period from September 2006 to September 2007. They signed an act of informed consent where the possible side effects are explained. Liquid nitrogen was applied with cotton applicators once a week after mechanical reduction. We made a clinical evolving evaluation fortnightly during the treatment, according to the elements and clinical characteristics referred by the patient, and proved by the physical examination carried out by the main investigator, because of the likelihood of short and long time side effects. This investigation demonstrated that cryotherapy is efficacious in treating plantar warts, since all the patients were healed in a short time period, most of them without side effects

    Analyses were performed to evaluate the performance of the low enriched uranium (LEU) conceptual design fuel for the conversion of the Transient Reactor Test Facility (TREAT) from its current highly enriched uranium (HEU) fuel. TREAT is an experimental nuclear reactor designed to produce high neutron flux transients for the testing of reactor fuels and other materials. TREAT is currently in non-operational standby, but is being restarted under the U.S. Department of Energy’s Resumption of Transient Testing Program. The conversion of TREAT is being pursued in keeping with the mission of the Department of Energy National Nuclear Security Administration’s Material Management and Minimization (M3) Reactor Conversion Program. The focus of this study was to demonstrate that the converted LEU core is capable of maintaining the performance of the existing HEU core, while continuing to operate safely. Neutronic and thermal hydraulic simulations have been performed to evaluate the performance of the LEU conceptual-design core under both steady-state and transient conditions, for both normal operation and reactivity insertion accident scenarios. In addition, ancillary safety analyses which were performed for previous LEU design concepts have been reviewed and updated as-needed, in order to evaluate if the converted LEU core will function safely with all existing facility systems. Simulations were also performed to evaluate the detailed behavior of the UO2-graphite fuel, to support future fuel manufacturing decisions regarding particle size specifications. The results of these analyses will be used in conjunction with work being performed at Idaho National Laboratory and Los Alamos National Laboratory, in order to develop the Conceptual Design Report project deliverable.

  18. Sexual Issues in Treating Trauma Survivors.

    Science.gov (United States)

    Zoldbrod, Aline P

    The effect of interpersonal trauma on sexuality can be profound. The field of sexual trauma is complex empirically and clinically, with contradictory theories and conflicting data. Research definitions and treatment protocols for child sexual abuse are very imprecise. There are no firm, empirically proven guidelines for treating men and women who have been sexually abused as children or adolescents. Overt sexual abuse (OSA) in children and adolescents is defined here as molestation, rape, or incest. Research has shown that OSA may, but does not necessarily, lead to sexual dysfunction in adulthood. The effects of OSA are worsened by concurrent types of family of origin abuse, such as emotional abuse or physical abuse. One factor that seems related to the varying impact of OSA on adult sexuality is the patients' family of origin experience with nonsexual Milestones of Sexual Development. Without positive experiences with touch, trust and empathy, the ability to relax and be soothed, and power, the effects of OSA are potentiated and complicated. Sexuality is embodied, so experiences with touch are particularly important when working with OSA. A three-color Body Map technique which assesses stored associations to touch is provided. The concept of developmental sexual trauma (DST) is introduced as a way to label traumagenic family events which potentiate OSA or negatively effect sex but which are not explicitly sexual in origin. Strategies to assess and treat OSA are reviewed. Body Maps are recommended to assess and treat sexual trauma.

    2016-12-07

    Anxiety is a common yet frequently overlooked psychiatric symptom in patients with ESRD treated with hemodialysis (HD). Anxiety is characterized by disruptive feelings of uncertainty, dread, and fearfulness. A variety of common medical complaints may be manifestations of an anxiety disorder, including palpitations, tremors, indigestion, numbness/tingling, nervousness, shortness of breath, diaphoresis, and fear. It is essential for the clinician to rule out specific medical conditions, including cardiovascular, pulmonary, and neurologic diseases, before ascribing these symptoms to an anxiety disorder. In addition, there is considerable overlap between the symptoms of anxiety and those of depression and uremia. This psychiatric condition has a significant adverse impact on patients' perception of quality of life. Little is known regarding the prevalence and impact of anxiety disorders in patients with ESRD treated with HD; however, many of the seemingly irrational behaviors of patients, or behaviors which place them in conflict with staff and physicians, such as behavioral noncompliance, may be the expression of an underlying anxiety disorder. In this review, we present three clinical vignettes, highlighting the impact of anxiety disorders in patients with ESRD treated with HD. Copyright © 2016 by the American Society of Nephrology.

  20. Municipal Treated Wastewater Irrigation: Microbiological Risk Evaluation

    Directory of Open Access Journals (Sweden)

    Antonio Lonigro

    2008-06-01

    Full Text Available Municipal wastewater for irrigation, though treated, can contain substances and pathogens toxic for humans and animals. Pathogens, although not harmful from an agronomical aspect, undoubtedly represent a major concern with regards to sanitary and hygienic profile. In fact, vegetable crops irrigated with treated wastewater exalt the risk of infection since these products can also be eaten raw, as well as transformed or cooked. Practically, the evaluation of the microbiological risk is important to verify if the microbial limits imposed by law for treated municipal wastewater for irrigation, are valid, thus justifying the treatments costs, or if they are too low and, therefore, they don’ t justify them. Different probabilistic models have been studied to assess the microbiological risk; among these, the Beta-Poisson model resulted the most reliable. Thus, the Dipartimento di Scienze delle Produzioni Vegetali of the University of Bari, which has been carrying out researches on irrigation with municipal filtered wastewater for several years, considered interesting to verify if the microbial limits imposed by the italian law n.185/03 are too severe, estimating the biological risk by the probabilistic Beta-Poisson model. Results of field trials on vegetable crops irrigated by municipal filtered wastewater, processed by the Beta-Poisson model, show that the probability to get infection and/or illness is extremely low, and that the actual italian microbial limits are excessively restrictive.

    Testicular cancer affects men mostly in their reproductive age with a cure rate over 90% and fertility is one of the main concerns of survivors. To further elucidate the question of fertility after treatment for testicular cancer, we performed a survey in patients treated in our institution. We sent a questionnaire to patients treated for testicular cancer at our institute from 1976 to 2002 (n = 490) of whom 297 (60.6%) responded. We considered the patients to have conserved fertility if they had children after treatment without assisted reproductive technologies. Before treatment 119/297 (40.1%) of patients and after treatment 150/297 (50.5%) of patients tried to have children (p = 0.019). Of 119 patients who tried to have children before treatment for testicular cancer 98 (82.4%) succeeded and 74/150 (49.3%) were successful after treatment (p years. The post-treatment fatherhood in patients treated with surgery only (orchidectomy +/- retroperitoneal lymphnode dissection-RPLND) was 59%, in those with additional radiotherapy 68%, and chemotherapy 50% (p = 0.233). Fertility rate in patients where a non nerve sparing RPLND was performed was only 37%, 62% in patients with nerve sapring RPLND, and 77% in patients where RPLND was not performed (p Fertility rate after treatment for testicular cancer is reduced. From our data, the most important treatment modality that influences fertility is non nerve sparing RPLND that should be avoided whenever possible in order improve the quality of life our patients.

  2. Effectiveness testing of spill-treating agents

    International Nuclear Information System (INIS)

    Fingas, M.F.; Stoodley, R.; Laroche, N.

    1990-01-01

    Laboratory effectiveness tests are described for four classes of spill-treating agents: solidifiers, demulsifying agents, surface-washing agents and dispersants. Many treating agents in these four categories have been tested for effectiveness and the results are presented. Solidifiers or gelling agents solidify oil, requiring a large amount of agent to solidify oil-ranging between 16% by weight, to over 200%. Emulsion breakers prevent or reverse the formation of water-in-oil emulsions. A newly-developed effectiveness test shows that only one product is highly effective; however, many products will work, but require large amounts of spill-treating agent. Surfactant--containing materials are of two types, surface-washing agents and dispersants. Testing has shown that an agent that is a good dispersant is conversely a poor surface-washing agent, and vice versa. Tests of surface-washing agents show that only a few agents have effectiveness of 25-40%, where this effectiveness is the percentage of heavy oil removed from a test surface. Results using the 'swirling flask' test for dispersant effectiveness are reported. Heavy oils show effectiveness values of about 1%, medium crudes of about 10%, light crude oils of about 30% and very light oils of about 90%. (author)

    Full text: Resistivity of insulators is an important property of materials used within the integrated circuit and packaging industries. The measurement of electrical resistivity of insulator materials in the surface region in this work is interpreted through observations of surface charge decay. A self-field driven and diffusion charge transport theory is used to model the process and resistivity values obtained computationally. Data for the charge decay of surface charged samples are collected by suspending them inside a coaxial cylinder connected to an electrometer. Samples used have been low density polyethylene LDPE sheet, both pristine and surface treated. Some samples have been treated by air plasma at low vacuum pressures for different periods of time; others have been washed in ethyl acetate and then plasma treated before the resistivity measurement. The sets of resistivity measurements form the various treatments are compared below. X-ray photoelectron spectroscopy (XPS) has also been used to investigate and account for the observed variations in surface resistivity

  4. Treat mine water using passive methods

    1993-01-01

    Passive treatment represents an alternative to conventional chemical treatment of coal mine drainage. When successful, passive systems require less investment, less maintenance and usually are less expensive than conventional chemical treatment systems. As a result, during the last seven years, more than 500 passive systems have been constructed in the United States to treat coal mine drainage. Some exist as an alternative to conventional treatment; others serve as an inexpensive pretreatment step than can decrease subsequent chemical requirements. Sulfide minerals present in rock disturbed during mining can oxidize to form an acidic metal-laden solution, commonly known as acid mine drainage (AMD). Alkalinity present in the rock may partially or completely neutralize AMD, but if either acidity or excessive metal contaminants remain, the water must be treated before it can be discharged legally. The principal regulated contaminant metals of coal mine drainage are iron and manganese. Metal mine drainage often contains more toxic metals, such as cadmium, nickel, copper and zinc. Chemical treatment of AMD is estimated to cost America's mining industry more than $1 million a day. Three principal passive technologies are used in the treatment of coal mine drainage: Aerobic wetlands, wetlands constructed with an organic substrate and anoxic limestone drains (ALDS). The selection of the technology or combination of technologies to be used depends on the quality of the water being treated

    Toxic epidermal necrolysis (TEN) is a rare and acute severe adverse reaction to drugs, characterised by massive apoptosis and widespread epidermal and mucosal detachment. Although no gold standard therapy exists, human i.v. immunoglobulins have recently been described as an effective treatment for this disease. We report a case of phenobarbital-induced TEN in a 59-year-old white woman where the epidermal detachment stopped 48 h after beginning the etanercept treatment with complete healing after 20 days. To the best of our knowledge, this is only the second reported case of TEN successfully treated with etanercept.

    2014-01-01

    PRP is widely used to treat tendon and other tissue injuries in orthopaedics and sports medicine; however, the efficacy of PRP treatment on injured tendons is highly controversial. In this commentary, I reason that there are many PRP- and patient-related factors that influence the outcomes of PRP treatment on injured tendons. Therefore, more basic science studies are needed to understand the mechanism of PRP on injured tendons. Finally, I suggest that better understanding of the PRP action mechanism will lead to better use of PRP for the effective treatment of tendon injuries in clinics.

  10. Asymptomatic Esophageal Varices Should Be Endoscopically Treated

    Directory of Open Access Journals (Sweden)

    Nib Soehendra

    1998-01-01

    Full Text Available Endoscopic treatment has generally been accepted in the management of bleeding esophageal varices. Both the control of acute variceal bleeding and elective variceal eradication to prevent recurrent bleeding can be achieved via endoscopic methods. In contrast to acute and elective treatment, the role of endoscopic therapy in asymptomatic patients who have never had variceal bleeding remains controversial because of the rather disappointing results obtained from prophylactic sclerotherapy. Most published randomized controlled trials showed that prophylactic sclerotherapy had no effect on survival. In some studies, neither survival rate nor bleeding risk was improved. In this article, the author champions the view that asymptomatic esophageal varices should be endoscopically treated.

    The radiological changes of solid craniopharyngiomas treated by stereotactic radiosurgery have been followed. Nine cases are considered, the patients having received gamma radiation treatment with a dose distribution permitting no part of the tumour to receive doses less than 2-3 Gy. Target doses were 20 to 50 Gy. Tumour shrinkage was registered and no complications which could be attributed with certainty to the irradiation were encountered. The results did not allow an optimal single dose to be determined with accuracy but vaguely indicated that lower doses than those used are sufficient for desired effect on the tumour without jeopardizing its surroundings.

    The aim of this study was to evaluate the effectiveness of different nanoparticles-based solutions for dentin permeability reduction and to determine the viscoelastic performance of cervical dentin after their application. Four experimental nanoparticle solutions based on zinc, calcium or doxycycline-loaded polymeric nanoparticles (NPs) were applied on citric acid etched dentin, to facilitate the occlusion and the reduction of the fluid flow at the dentinal tubules. After 24 h and 7 d of storage, cervical dentin was evaluated for fluid filtration. Field emission scanning electron microscopy, energy dispersive analysis, AFM and Nano-DMA analysis were also performed. Complex, storage, loss modulus and tan delta (δ) were assessed. Doxycycline-loaded NPs impaired tubule occlusion and fluid flow reduction trough dentin. Tubules were 100% occluded in dentin treated with calcium-loaded NPs or zinc-loaded NPs, analyzed at 7 d. Dentin treated with both zinc-NPs and calcium-NPs attained the highest reduction of dentinal fluid flow. Moreover, when treating dentin with zinc-NPs, complex modulus values attained at intertubular and peritubular dentin were higher than those obtained after applying calcium-NPs. Zinc-NPs are then supposed to fasten active dentin remodeling, with increased maturity and high mechanical properties. Zinc-based nanoparticles are then proposed for effective dentin remineralization and tubular occlusion. Further research to finally prove for clinical benefits in patients with dentin hypersensitivity using Zn-doped nanoparticles is encouraged. Erosion from acids provokes dentin hypersensitivity (DH) which presents with intense pain of short duration. Open dentinal tubules and demineralization favor DH. Nanogels based on Ca-nanoparticles and Zn-nanoparticles produced an efficient reduction of fluid flow. Dentinal tubules were filled by precipitation of induced calcium-phosphate deposits. When treating dentin with Zn-nanoparticles, complex modulus

    Digitizing the technical drawings for EBR-II and TREAT provides multiple benefits. Moving the scanned or hard copy drawings to modern 3-D CAD (Computer Aided Drawing) format saves data that could be lost over time. The 3-D drawings produce models that can interface with other drawings to make complex assemblies. The 3-D CAD format can also include detailed material properties and parametric coding that can tie critical dimensions together allowing easier modification. Creating the new files from the old drawings has found multiple inconsistencies that are being flagged or corrected improving understanding of the reactor(s).

    Spinal cord injury results in significant mortality and morbidity, lifestyle changes, and difficult rehabilitation. Treatment of spinal cord injury is challenging because the spinal cord is both complex to treat acutely and difficult to regenerate. Nanomaterials can be used to provide effective treatments; their unique properties can facilitate drug delivery to the injury site, enact as neuroprotective agents, or provide platforms to stimulate regrowth of damaged tissues. We review recent uses of nanomaterials including nanowires, micelles, nanoparticles, liposomes, and carbon-based nanomaterials for neuroprotection in the acute phase. We also review the design and neural regenerative application of electrospun scaffolds, conduits, and self-assembling peptide scaffolds.

    Purpose To observe the curative effect of electroacupuncture in treating depression. Method Two hundred and ten subjects were randomly divided into electroacupuncture group and medication group. Results and conclusion The results were evaluated by an international depression scale in both groups. After one-course treatment, the average score markedly decreased in both groups, and a t-test showed that there was a significant difference in curative effect between before and after treatment in each group ( P 0.05 ).Electroacupuncture can be compared favorably with amitriptyline, an antidepressant. However, taking amitriptyline will produce some side effects. Therefore electroacupuncture is especially suitable for those who cannot take medicine.

    Both higher corrosion resistance and paint adherence are given to films formed on the surfaces of metals by treating the surfaces with aqueous solutions of one or more materials selected from the group consisting of water soluble vinyl monomer or water soluble high polymer and then irradiating with ionizing radioactive rays on the nearly dried surface film. When a water soluble inorganic compound is mixed with the above mentioned aqueous solution, the film properties are greatly improved. The inorganic ionic material should contain a cation from the group consisting of Ca, Mg, Zn, Cr, Al, Fe, and Ni. Electron beams may be used. (U.S.)

    Treated green diamonds can show residual radioactivity, generally due to immersion in radium salts. We report various activity measurements on two radioactive diamonds. The activity was characterized by alpha and gamma ray spectrometry, and the radon emanation was measured by alpha counting of a frozen source. Even when no residual radium contamination can be identified, measurable alpha and high-energy beta emissions could be detected. The potential health impact of radioactive diamonds and their status with regard to the regulatory policy for radioactive products are discussed. Copyright © 2017. Published by Elsevier Ltd.

    1977-01-01

    A study on dewatering properties of radiosterilized sewage sludge of different type and origin was carried out. For comparison, also heat-treated (pasteurized) sludge was investigated. The specific filtration resistance of irradiated sewage sludge was lowered in all types of sludge examined. In general, pasteurization increased this parameter. The settling properties of irradiated digested sewage sludge was slightly improved, mainly in the first hours after treatment. Microbial effects may mask the real sedimentation relations especcially in aerobically stabilized sludges. A pasteurization treatment of sewage sludge caused an increased content of soluble substances and suspended particles in the supernatant water. The supernatant water from irradiated sludge showed a smaller increase

    Full Text Available Telogen effluvium is a non-scarring form of hair loss. Clinically, the disease is characterized by hair loss where more than normalamounts of hair fall out; it usually affects the whole scalp in a widespread manner. When hair loss is very pronounced and persists fora long time, alopecia becomes clinically evident. It is not associated to subjective symptoms. In this paper, the authors describe theclinical case of a 67-year old patient suffering from telogen effluvium, treated with a supplement containing amino acids (L-cystineand L-methionine, vitamin E, iron and extract of Serenoa repens.

    Sural neuralgia is persistent pain in the distribution of the sural nerve that provides sensation to the lateral posterior corner of the leg, lateral foot, and fifth toe. Sural neuralgia is a rare condition but can be challenging to treat and can cause significant limitation. We present 2 cases of sural neuralgia resistant to conservative management that were effectively treated by pulsed radiofrequency ablation. A 65-year-old female developed sural neuralgia after a foot surgery and failed conservative management. She had successful sural nerve blocks, and pulsed radiofrequency ablation led to an 80% improvement in her pain. A 33-year-old female presented with sural neuralgia secondary to two falls. The patient had tried several conservative modalities with no success. We performed diagnostic blocks and pulsed radiofrequency ablation, and the patient reported 80% improvement in her pain. Pulsed radiofrequency ablation may be a safe and effective treatment for patients with sural neuralgia that does not respond to conservative therapy. However, studies are needed to elucidate its effectiveness and safety profile.

    Full Text Available Nowadays natural products interest has increased. However, when some products are included on textile fibers, they have no affinity and need some binders or other kind of auxiliaries to improve the yeld of the process, and some of them are not so natural as the product which are binding and consequently the “bio” definition is missed as some of them can be considered as highly pollutant. Chitosan is a common used bonding agent for cotton. It improves the antimicrobial and antifungal activity, improves wound healing and is a non-toxic bonding agent. The biopolymer used in this work is chitosan, which is a deacetylated derivative of chitin. These properties depend on the amount of deacetylation (DD and the Molecular weight (MW. Along with these improving properties, as it requires some acid pH to ve solved the treatment with chitosan can have some decreasing mechanical properties. The aim of that paper is to evaluate the change in breaking force of the treated samples and a change in elongation of those samples. It compared different amounts of concentration of chitosan with non treated cotton. The traction resistance test were performed on a dynamometer. The test was conducted according to the UNE EN ISO 13934-1 standard.

    2011-01-01

    Mycoplasma genitalium is associated with acute and chronic urethritis in men. Existing data on infection in women are limited and inconsistent but suggest that M. genitalium is associated with urethritis, cervicitis, pelvic inflammatory disease, and possibly female infertility. Data are inconclusive regarding the role of M. genitalium in adverse pregnancy outcomes and ectopic pregnancy. Available data suggest that azithromycin is superior to doxycycline in treating M. genitalium infection. However, azithromycin-resistant infections have been reported in 3 continents, and the proportion of azithromycin-resistant M. genitalium infection is unknown. Moxifloxacin is the only drug that currently seems to uniformly eradicate M. genitalium. Detection of M. genitalium is hampered by the absence of a commercially available diagnostic test. Persons with persistent pelvic inflammatory disease or clinically significant persistent urethritis or cervicitis should be tested for M. genitalium, if possible. Infected persons who have not previously received azithromycin should receive that drug. Persons in whom azithromycin therapy fails should be treated with moxifloxicin. PMID:22080266

    1993-12-31

    A wastewater disinfection system developed by a Canadian company, Trojan Technologies Inc., was discussed. Disinfection for pathogen reduction prior to discharge of treated municipal wastewater back into rivers and lakes has been either ignored or treated by the use of chemicals. In 1979 the first pilot ultraviolet (UV) wastewater disinfection system was established. Since then, over 500 municipal UV installations have been commissioned. The largest installation can process 212 million gallons of water per day. The advantages of UV as a disinfectant are: (1) It is more effective than chlorine. (2) There are no mutagenic/carcinogenic byproducts formed with UV. (3) No toxic chemical residuals are discharged. (4) UV is safe to both the operators and the public. (5) It is cost effective. Europe has not been as active in wastewater disinfection as has North America. One result of the absence of wastewater disinfection in Europe is that the Rhine River, for example, carries 50 million salmonella per second. Disinfection of wastewater effluents is, of course, indispensable in protecting our drinking water supply. 2 figs.

    It is generally believed that there are some connections between Alzheimer's disease and amyloid protein plaques in the brain. The typical symptoms of Alzheimer's disease are memory loss, language disorders, mood swings, loss of motivation and behavioral issues. Currently, the main therapeutic method is pharmacotherapy, which may temporarily reduce symptoms, but has many side effects. Infrared light therapy has been studied in a range of single and multiple irradiation protocols in previous studies and was found beneficial for neuropathology. In our research we have studied the effect of infrared light on Alzheimer's disease through transgenic mouse model. We designed an experimental apparatus for treating mice, which primarily included a therapeutic box and a LED array, which emitted infrared light. After the treatment, we assessed the effects of infrared light by performing two tests: cognitive performance of mice in Morris water maze, and plaque load by immunofluorescence analysis. Immunofluorescence analysis was based on measuring the quantity of plaques in mouse brain slices. Our results show that infrared therapy is able to improve cognitive performance in the mouse model. It might provide a novel and safe way to treat Alzheimer's disease.

    The curability of 168 squamous cell carcinomas of the esophagus treated with more than 60 Gy of irradiation between 1980 and 1987 were discussed. There were 49 autopsied cases. The curability rat was calculated after the conversion of 13 local free or 46 metastasis free patients who had not undergone autopsy into unknown cases in each analysis. Disease free, local free, and metastasis free rates were 11.2, 20.0, and 26.0%, respectively. The curability rate was higher in the superficial type cancer and stage I cases. The local control rate and the metastasis free rate were extremely poor in the infiltrative type cancer. The actuarial survival rate of overall patients was 31.5% at one year, 11.3% at three years, and 7.1% at five years. Reconstructed survival rates: disease free, local free, and metastasis free survival rates, indicated that the survival rates of overall patients might be improved by decreasing the number of intercurrent death in stage I and by elevating the ratio of the local control in stages II and III. The disease free survival rate of cases treated with low dose rate telecobalt therapy as a boost was better than that of the conventionally fractionated irradiation alone cases in stages II and III.

    To study the outcome of Radioactive Iodine (RAI) in treatment of hyperthyroidism. It is a retrospective study of all patients of hyperthyroidism treated by Radioactive Iodine (RAI) seen in endocrinology clinic at King Abdulaziz University Hospital and Dr. Soliman Fageeh Hospital in Jeddah, Saudia Arabia. Two hundred and sixteen (216) patients were treated by RAI. They proved to have hyperthyroidism by thyroid function test (TSH, FT4 and T3) and isotopes scanning of the thyroid gland. All received 10 mci of RAI and were then followed up after one month and every two months thereafter for at least one year. The efficacy of the therapy was assessed by the improvement of the clinical features and by the thyroid function tests. A total of 216 patients were seen, the mean age was 36.5+- 10.64 years. One hundred fifty three were female and sixty three were male. Graves disease was the underlying cause in 163 patients [65.55%], toxic multi nodular goiter in 37 patients [25.1%] and toxic adenoma in 16 patients [9.3%]. The symptoms improved after one month only in 11 patients but others required antithyroid treatment for two months. Only 17 patients remained hyperthyroid after six months of treatment. Radioactive iodine is very effective in treatment of hyperthyroidism with minor side effects such as weight gain, fatigability and hypothyroidism. (author)

    Idiopathic toe walking (ITW) causes a common problem in pediatric orthopaedics. In the literature, numerous treatment options have been reported, but consensus about the management of ITW is still missing. The aim of the current study was to evaluate conservative treatment with pyramidal insoles. A total of 193 patients underwent conservative treatment between January 2010 and June 2013. Mean age at the beginning of the treatment was 7.75 ± 0.23 years (range 2.0-17.0 years). For all patients, demographic data, comorbid diseases, passive range of motion (ROM), persistent toe walking, and performed operations were retrospectively evaluated. Following operative treatment was defined failure. Eight (4.15%) patients underwent Achilles tendon lengthening operation after mean therapy time of 2.72 years (range 0.1-7.0 years), 174 cases were treated successfully (90.16%). In 50 cases, toe walking suspended completely after mean therapy time of 2.83 years. In cases of failure, patients were older at diagnosis and at the beginning of the treatment. Mean passive ROM increased over the time. In cases of failure, ROM decreased from the first to the second examination. Conservative treatment of ITW using pyramidal insoles can be effective. Ankle dorsiflexion significantly improved in the patients who were successfully treated. Therapy should start early. A decrease of ROM under therapy should lead to critical revisal of individual therapy. Therapeutic, level IV: Case series.

    2001-01-01

    The first reported application of uterine artery embolization, in 1979, was to treat life-threatening hemorrhage after a failed hysterectomy. Since then, uterine artery embolization has been used very successfully to control acute or delayed post-partum hemorrhage, post-surgical hemorrhage and hemorrhage from ectopic pregnancy, to treat uterine arteriovenous malformations and as prophylaxis before high-risk surgery, such as cesarean delivery in women with placenta previa. In contrast to these proven but underutilized applications, uterine embolization for fibroids has, in a short time, achieved significant notice in the lay press and is being widely offered. Ravina and colleagues, first reported uterine fibroid shrinkage after embolization for the treatment of acute bleeding. Since then, his group has performed over 100 procedures with up to a 6-year follow-up. The cumulative clinical success rate for the treatment of abnormal uterine bleeding due to fibroids is reported to be approximately 85% and for treatment of pain or pressure symptoms, about 75%. Six-month follow-up sonography reveals an average reduction of fibroid size of approximately 40%. However, to date, no studies have compared patients who undergo embolization with a nontreatment cohort or with surgical intervention. (author)

    During the last French radiation oncology society annual congress, the therapeutic options for the management of brain metastases were presented. The indications and limits of surgery, stereotactic radiotherapy and whole brain radiotherapy, as well as their benefit in terms of overall survival, local control and improvement of the functional and neuro-cognitive status were discussed. The prognosis significance of the different phenotypes of breast cancer on the risk for BM as well as their roles in the treatment of brain metastases were also described. Surgery improves overall survival for patients with a single brain metastase and should be considered in the case of symptomatic lesions. The overall survival of patients treated with stereotactic radiotherapy do not differ from that of patients treated with surgery. These treatments should be mainly considered for patients with good performance status, one to three small brain metastases (< 3 cm) and limited extracranial disease. Whole brain radiotherapy is more and more discussed in adjuvant setting due to potential late neuro-cognitive toxicity. This toxicity could be improved with the development of techniques sparing the hippocampus. HER2+ and triple-negative breast cancer patients are at increased risk for brain metastases. Prognosis of these patients differs as the overall survival of HER2+ patients has improved with anti-HER2 therapies. The optimal combination of local and systemic therapies remain to be determined.

  13. Treating oil in a maritime environment

    International Nuclear Information System (INIS)

    Seebacher, G.

    2002-01-01

    Some details of the International Maritime Organisation's marine pollution regulations are discussed. In simple terms, under IMO regulations oily water must be processed through approved equipment and can be legally discharged if the oil content in the treated effluent is less than 15 ppm. These regulations also make it clear that it is not permitted to use emulsifiers to hide the oil in the effluent. To separate the free oil from water, gravity enhanced separators can be used effectively. With conventional means it is possible to remove free oil from an oily water mixture, to the less than 15 part per million oil content. Conventional IMO certified oil content meters accurately read free oil content in the 0-30 ppm region, to prevent formation of an oil film from treated oily water discharges. Some additional basic rules of thumb worthy of consideration when separating oil from oily water: in general, it is cheaper to prevent oil discharge of oil into the effluent stream than to remove it; emulsifier-enriched lubricating oils emulsify readily and are difficult to remove when present in suspended droplets; the larger the amount of contamination, the greater the difficulty of removing the oil; an ounce of prevention is worth a pound of cure

  14. Solar urticaria successfully treated with intravenous immunoglobulin.

    2012-02-01

    Idiopathic solar urticaria (SU) is a rare, debilitating photodermatosis, which may be difficult to treat. First-line treatment with antihistamines is effective in mild cases, but remission after phototherapeutic induction of tolerance is often short-lived. Other treatment options include plasma exchange, photopheresis and cyclosporin. We present two cases of severe, idiopathic SU, which were resistant to conventional treatment. Both patients achieved remission after administration of intravenous immunoglobulin (IVIg) and have remained in remission at 13 months and 4 years, respectively. There are only two case reports of successful treatment of solar urticaria with IVIg. In our experience IVIg given at a total dose of 2 g\\/kg over several 5-day courses about a month apart is an effective treatment option for severe idiopathic SU. It is also generally safe, even if certainly subject to significant theoretical risks, such as induction of viral infection or anaphylaxis.

    Full Text Available Childhood obesity is one of the most dangerous pathologies; it can lead to serious illness in the absence of medical support. In this article we give an overview of the use of videogames for reducing and normalizing the weight of overweight and obese children. We discuss the categorization of the existing games and their limits, and we outline the perspectives of psychopedagogical research in the domain of game design for treating obese and overweight children. The role of long-term motivation in the treatment of obesity is one of the crucial questions we discuss. We try to understand how videogames can help children and parents maintain motivation during weight-loss treatment. The role of parents is undeniable in ensuring the success of weight-loss programs for overweight or obese children. Perhaps videogames can be the instrument for families’ lifestyle changes.

    Hishikawa, Y.; Tanaka, S.; Miura, T.

    1985-01-01

    Five patients with early esophageal carcinoma were treated by 6-12 Gy of intracavitary irradiation following 50-60 Gy of external irradiation as a boost therapy. Surgery was not performed in these cases. None of the patients had local recurrence after radiation therapy, as demonstrated by esophagography and endoscopy. Three patients have been alive for 1-3 years 10 months. Esophageal ulceration induced by intracavitary irradiation has occurred in three of the five patients; however, intracavitary irradiation is still a beneficial treatment because of its efficacy in controlling local lesions and because radiation ulceration can eventually be cured. Intracavitary irradiation is recommended to follow external irradiation as a boost therapy for the treatment of early esophageal carcinoma

  18. The debate on treating subclinical hypothyroidism

    Science.gov (United States)

    Tng, Eng Loon

    2016-01-01

    Subclinical hypothyroidism (SCH) represents a mild or compensated form of primary hypothyroidism. The diagnosis of SCH is controversial, as its symptoms are non-specific and its biochemical diagnosis is arbitrary. The treatment of SCH was examined among non-pregnant adults, pregnant adults and children. In non-pregnant adults, treatment of SCH may prevent its progression to overt hypothyroidism, reduce the occurrence of coronary heart disease, and improve neuropsychiatric and musculoskeletal symptoms associated with hypothyroidism. These benefits are counteracted by cardiovascular, neuropsychiatric and musculoskeletal side effects. SCH is associated with adverse maternal and fetal outcomes that may improve with treatment. Treating SCH in children is safe and may improve growth. Importantly, the evidence in this field is largely from retrospective and prospective studies with design limitations, which precludes a conclusive recommendation for the treatment of SCH.

In order to develop this work, a continuous separation unit, characterized by the solvent extraction, carried out inward the ejector is used. Alamina 336 (a mixture of tri-octyl and tri-decyl amines) is used as extractant in this process. The splitting of the amine-water emulsion formed is carried out in a gravitational separation tank. The result showed that it is possible to reach an efficiency of about 95% for the uranium extraction, for metal concentration in the feed of 10 ppm and a Q fa /Q fo ratio around 500. Furthermore, an efficiency of about 50% is reached for metal concentration in the feed of 1 ppm and for aQ fa /Q fo ratio around 1000, when the liquid flow rate is equal 1200 L/h. (author)

    Radioactive liquid wastes generated at BWR plants are collected and treated as required. These days, however, generation of floor drain has deceased and HFF (Hollow Fiber Filter) has experienced a wide applicability to several kinds of liquid wastes. We should consider that the floor drain can be mixed and diluted with equipment drain and be purified by HFF. That enables some of the sumps and long priming pipes to be combined. From this point of view, we have developed a highly rationalized waste liquid system. We have evaluated the applicability of this system after an investigation into the generation and properties of floor drain and equipment drain at the latest BWR'S and an on-site test at a typical BWR.

    1992-01-01

    The purpose is to study the theory of electrocoagulation during water treatment. Mechanisms proposed in the literature are charge neutralization and dipole-dipole interaction. The electrokinetics of highly concentrated model clay and process clay suspensions, before and after electrocoagulation, are studied experimentally. The charge on treated and untreated dispersions and controls are measured using electrokinetic sonic amplitude and microelectrophoresis techniques. Scanning electron microscopy is used to determine release of aluminum ions onto latex and process clays. The qualitative experimental observations, electrokinetic data, and analysis of aluminum coated particles provide some information on the mechanisms of electrocoagulation, but further studies with dilute dispersions are needed to confirm the charge neutralization mechanism. 10 refs., 4 figs., 3 tabs.

    1978-01-01

    Psoralen-ultraviolet light (PUVA)-treated psoriatic lesions were studied for ultrastructural changes. In early stages of treatment, sunburn cells in the epidermis and bizarre giant cells in the dermis were more frequently observed. When clinical improvement was apparent, these changes had subsided. Dermal abnormality in long-term therapy consisted of a thick perivascular cost of amorphous substance. No abnormality was found in the epidermal keratinocytes in long-term therapy, except a clustering and giant cell formation of melanocytes, a heavy melanization of keratinocytes, and hyperkeratosis. Low-dose initiation and slow increment of both 8-methoxypsoralen and UVA is probably a reasonable regimen for benign dermatoses such as psoriasis because it will allow enough time for the skin to become more protected, while the therapeutic results are as satisfactory as in a high-dose schedule

    Currently available antidepressant medications are equally effective in treating HIV/AIDS patients and the general population. Furthermore, intervention studies have shown that psychotherapy reduces depressive symptoms and is well tolerated. Interpersonal psychotherapy is more successful than supportive psychotherapy in lessening depression, and patients experience improved functioning physically and emotionally. Untreated depression may be associated with reduced adherence to ART, immunosuppression, and more rapid HIV illness progression. In South Africa, HIV/AIDS patients may be at greater risk for psychiatric disorder given the potentially stressful living conditions including high rates of unemployment and poverty, poor and unstable housing, inadequate social services, and high rates of crime and domestic violence. A lack of data on depression in South Africa underscores the need for further research.

  4. Cytocompatibility of Plasma and Thermally Treated Biopolymers

    Full Text Available This paper is focused on the surface characterization of plasma and consequently thermally treated biocompatible polymers. PLLA (poly(L-lactide acid and PMP (poly-4-methyl-1-pentene are studied. The influence of Ar plasma treatment on the surface polarity of substrate measured immediately after treatment and during the polymer surface aging is studied. Surface roughness, morphology, wettability, and surface chemistry were determined. Plasma treatment leads to significant changes in PLLA surface morphology and chemistry, with the PMP being slightly affected. The higher resistance to plasma fluence results in smaller ablation of PMP than that of PLLA. The plasma treatment improves cell adhesion and proliferation on the PMP. Plasma treatment of PLLA influences mostly the homogeneity of adhered and proliferated VSMC.

  5. Silver deposition on chemically treated carbon monolith

    2009-01-01

    Full Text Available Carbon monolith was treated with HNO3, KOH and H2O2. Effects of these treatments on the surface functional groups and on the amount of silver deposited on the CM surface were studied by temperature programmed desorption (TPD and atomic absorption spectrometry (AAS. As a result of chemical treatment there was an increase in the amount of surface oxygen complexes. The increase in the amount of silver deposit is proportional to the amount of surface groups that produce CO under decomposition. However, the high amount of CO groups, decomposing above 600°C, induces the smaller Ag crystallite size. Therefore, the high temperature CO evolving oxides are, most likely, the initial centers for Ag deposition.

  6. Process and system for treating waste water

    Olesen, Douglas E.; Shuckrow, Alan J.

    1978-01-01

    A process of treating raw or primary waste water using a powdered, activated carbon/aerated biological treatment system is disclosed. Effluent turbidities less than 2 JTU (Jackson turbidity units), zero TOC (total organic carbon) and in the range of 10 mg/l COD (chemical oxygen demand) can be obtained. An influent stream of raw or primary waste water is contacted with an acidified, powdered, activated carbon/alum mixture. Lime is then added to the slurry to raise the pH to about 7.0. A polyelectrolyte flocculant is added to the slurry followed by a flocculation period -- then sedimentation and filtration. The separated solids (sludge) are aerated in a stabilization sludge basin and a portion thereof recycled to an aerated contact basin for mixing with the influent waste water stream prior to or after contact of the influent stream with the powdered, activated carbon/alum mixture.

    Skin diseases are numerous and a frequently occurring health problem affecting all ages from the neonates to the elderly and cause harm in number of ways. Maintaining healthy skin is important for a healthy body. Many people may develop skin diseases that affect the skin, including cancer, herpes and cellulitis. Some wild plants and their parts are frequently used to treat these diseases. The use of plants is as old as the mankind. Natural treatment is cheap and claimed to be safe. It is also suitable raw material for production of new synthetic agents. A review of some plants for the treatment of skin diseases is provided that summarizes the recent technical advancements that have taken place in this area during the past 17 years. PMID:24600196

    The main control algorithm of the Transient Reactor Test Facility (TREAT) Automatic Reactor Control System (ARCS) resides in Read Only Memory (ROM) and only experiment specific parameters are input via keyboard entry. Prior to executing an experiment, the software and hardware of the control computer is tested by a closed loop real-time simulation. Two computers with parallel processing are used for the reactor simulation and another computer is used for simulation of the control rod system. A monitor computer, used as a redundant diverse reactor protection channel, uses more conservative setpoints and reduces challenges to the Reactor Trip System (RTS). The RTS consists of triplicated hardwired channels with one out of three logic. The RTS is automatically tested by a digital Dedicated Microprocessor Tester (DMT) prior to the execution of an experiment. 6 refs., 5 figs., 1 tab

  9. The debate on treating subclinical hypothyroidism.

    Tng, Eng Loon

    2016-10-01

    Subclinical hypothyroidism (SCH) represents a mild or compensated form of primary hypothyroidism. The diagnosis of SCH is controversial, as its symptoms are non-specific and its biochemical diagnosis is arbitrary. The treatment of SCH was examined among non-pregnant adults, pregnant adults and children. In non-pregnant adults, treatment of SCH may prevent its progression to overt hypothyroidism, reduce the occurrence of coronary heart disease, and improve neuropsychiatric and musculoskeletal symptoms associated with hypothyroidism. These benefits are counteracted by cardiovascular, neuropsychiatric and musculoskeletal side effects. SCH is associated with adverse maternal and fetal outcomes that may improve with treatment. Treating SCH in children is safe and may improve growth. Importantly, the evidence in this field is largely from retrospective and prospective studies with design limitations, which precludes a conclusive recommendation for the treatment of SCH.

    Bostwick, J Michael; Bucci, Jeffrey A

    2008-02-01

    Malfunctioning of the brain's reward center is increasingly understood to underlie all addictive behavior. Composed of mesolimbic incentive salience circuitry, the reward center governs all behavior in which motivation has a central role, including acquiring food, nurturing young, and having sex. To the detriment of normal functioning, basic survival activities can pale in importance when challenged by the allure of addictive substances or behaviors. Dopamine is the neurotransmitter driving both normal and addictive behavior. Other neurotransmitters modulate the amount of dopamine released in response to a stimulus, with the salience determined by the intensity of the dopamine pulse. Opiates (either endogenous or exogenous) exemplify such modulators. Prescribed for treating alcoholism, naltrexone blocks opiates' capacity to augment dopamine release. This article reviews naltrexone's mechanism of action in the reward center and describes a novel use for naltrexone in suppressing a euphorically compulsive and interpersonally devastating addiction to Internet pornography.

    Plant roots are very important organs in terms of nutrient and water acquisition but they also serve as anchorages for the aboveground parts of the plants. The roots display extraordinary plasticity towards stress conditions as a result of integration of environmental cues into the developmental processes of the roots. Our aim was to investigate the root morphology of Arabidopsis thaliana plants exposed to a particular stress condition, excess Ni supply. We aimed to find out which cellular processes - cell division, elongation and differentiation are affected by Ni, thereby explaining the seen root phenotype. Our results reveal that a distinct sensitivity exists between roots of different order and interference with various cellular processes is responsible for the effects of Ni on roots. We also show that Ni-treated roots have several auxin-related phenotypes. (authors)

    2017-01-01

    Full Text Available Background: Dysmenorrhea has a high prevalence among women, especially in young women. Zinc has been proved to have a beneficial effect in treating pain. The aim of this study is to determine the effectiveness of zinc supplementation in treating dysmenorrhoeal pain. Method: This is an experimental study, using pre and post-test design. The study participants were medical staffs of H. Adam Malik Hospital and other satellite hospitals. This study was conducted on March 2016 to June 2016. Thirty seven patients with moderate to severe primary menstrual pain were given 30 mg of zinc per day (divided into two doses, 2 days prior to menstruation until its cessation, for two to three months. The pain was assessed with the visual analog scale (VAS. Results: The mean age of participants was 22.95±1.33 years old and the mean body weight, height, and body mass index were 55.54 ± 9.36 kg, 160.16 ± 5.46 cm, 22.02 ± 3.44 kg/m2, respectively. The mean pain score is higher prior to zinc supplementation (4.92 ± 1.80; moderate pain and the score decreased over three months of zinc supplementation, resulting in a mean score of 2.7 ± 2.03 (moderate pain. The differences were found to be statistically significant (p = 0.000. Conclusion: Dysmenorrhea is frequently found in young women. Two to three months of zinc supplementation during menstruation is proved to be useful in reducing the intensity of dysmenorrheal pain.

  14. Understanding and treating vaginismus: a multimodal approach.

    2014-12-01

    This clinical opinion was written to bring attention to the understanding and treatment of vaginismus, a condition that is often under diagnosed and therefore inadequately treated, yet affects millions of women worldwide. Despite its description more than a century ago, vaginismus is rarely taught in medical school, residency training, and medical meetings. The DSM 5 classification stresses that vaginismus is a penetration disorder in that any form of vaginal penetration such as tampons, finger, vaginal dilators, gynecological examinations, and intercourse is often painful or impossible. Compared with other sexual pain disorders such as vulvodynia and vestibulodynia, the treatment of vaginismus has the potential for a high rate of success. Stratifying the severity of vaginismus allows the clinician to choose among numerous treatment options and to better understand what the patient is experiencing. Vaginismus is both a physical and an emotional disorder. In the more severe cases of vaginismus women (and men) complain that attempted intercourse is like "hitting a wall" suggestive of spasm at the level of the introitus. The emotional fallout resulting from this needs to be addressed in any form of treatment applied. This article is based on lessons learned in the treatment of more than 250 patients and evaluation of more than 400 inquiries, and was written to make vaginismus more widely understood, to aid in the differential diagnosis of sexual pain, suggest a variety of effective treatments, and explain how Botox can be used as part of a multimodal treatment program to treat vaginismus. With greater awareness among clinicians it is hoped that medical schools, residency programs, and medical meetings will begin teaching the understanding and treatment of vaginismus.

    A single, open and non comparative study was conducted at Anwar Shah Trust for C.P. & Paralysis in collaboration with the Departments of Neurology and Neurosurgery, Children Hospital Lahore, Pakistan to evaluate the effects of ACULASER THERAPY in childern suffering from Cerebral Palsy (C.P.) and associated Neurological Disorders like epilepsy, cortical blindness, spasticity, hemiplegia, paraplegia, diplegia, quadriplegia, monoplegia, sensory-neural deafness and speech disorders. In all 250 childern were treated and the data was gathered during a period of 3 years from December 2003 till December 2006. These children were further classified according to the type of C.P. (spastic, athetoid, mixed) they suffered from and associated Neurological Disorders. This article shows results in C.P. childern who were treated with ACULASER THERAPY for minimum 6 weeks and more or had minimum of 15 treatment sessions and more. This article also shows that those childern who were given a break in the treatment for 1 month to 1 year did not show any reversal of the signs and symptoms. Analysis of the data showed that out of 171 children with Spasticity and Stiffness 147 showed marked improvement showing 87% success rate, out of 126 children with Epileptic fits, there was a significant reduction in the intensity, frequency and duration of Epileptic fits in 91 children showing 72% success rate, out of 48 children with Cortical Blindness 30 children showed improvement accounting for 63% efficacy rate, out of 105 children with Hearing Difficulties, 63 showed marked improvement accounting for 60% improvement rate, out of 190 children with Speech Disorders 122 showed improvement reflecting 64% improvement rate, out of 96 children with Hemiplegia 71 showed improvement in movement, tone and power accounting for 74% improvement rate, out of 76 children with Quadriplegia 52 showed improvement in gross and fine motor functions showing 69% success rate and out of 58 children with Paraplegia of

    Full Text Available Introduction. In addition to significant prevalence of generalized anxiety disorder (GAD and related consequences, it seems that this disorder has not been studied sufficiently in Serbia. Objective. The aim of this study was to investigate the understanding of psychopathology and the adequate treatment of patients with GAD by psychiatrists in Serbia. Methods. The study comprised 84 doctors - psychiatrists and neuropsychiatrists who were engaged in treatment of patients with GAD. Anonymous survey was used as the basic instrument, which collected information about the socio-demographic and professional data, experience in treating GAD and understanding psychopathology of GAD, as well as the first and the second choice therapy for patients with GAD. Results. The majority of psychiatrists (62.2% indicated the symptoms of distress/tension and slightly lower percent (36.6% designated the symptoms of worry/anxiety as the key symptoms of GAD when it was diagnosed. The results showed that almost all patients (96.5% had been treated with benzodiazepines before coming to psychiatrists. Most psychiatrists preferred the use of SSRI/SNRI antidepressants (76.2%, usually in combination with benzodiazepines (71.4% for the treatment of patients with GAD; however, if these doctors got GAD, the preference of benzodiazepine use would be significantly lesser (45.2% than for the treatment of their patients. Preference for the use of SSRI/SNRI antidepressants was significantly more frequent in physicians with completed residency. Conclusion. The understanding of psychopathology and treatment practice for patients with GAD in this sample of psychiatrists in Serbia is mostly consistent with the current trends for GAD treatment.

  17. Anabolic steroids for treating pressure ulcers.

    2017-06-20

    Pressure ulcers, also known as bed sores, pressure sores or decubitus ulcers develop as a result of a localised injury to the skin or underlying tissue, or both. The ulcers usually arise over a bony prominence, and are recognised as a common medical problem affecting people confined to a bed or wheelchair for long periods of time. Anabolic steroids are used as off-label drugs (drugs which are used without regulatory approval) and have been used as adjuvants to usual treatment with dressings, debridement, nutritional supplements, systemic antibiotics and antiseptics, which are considered to be supportive in healing of pressure ulcers. Anabolic steroids are considered because of their ability to stimulate protein synthesis and build muscle mass. Comprehensive evidence is required to facilitate decision making, regarding the benefits and harms of using anabolic steroids. To assess the effects of anabolic steroids for treating pressure ulcers. In March 2017 we searched the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL); Ovid MEDLINE (including In-Process & Other Non-Indexed Citations); Ovid Embase and EBSCO CINAHL Plus. We also searched clinical trials registries for ongoing and unpublished studies, and scanned reference lists of relevant included studies as well as reviews, meta-analyses and health technology reports to identify additional studies. There were no restrictions with respect to language, date of publication or study setting. Published or unpublished randomised controlled trials (RCTs) comparing the effects of anabolic steroids with alternative treatments or different types of anabolic steroids in the treatment of pressure ulcers. Two review authors independently carried out study selection, data extraction and risk of bias assessment. The review contains only one trial with a total of 212 participants, all with spinal cord injury and open pressure ulcers classed as stage III and IV. The participants were

    Despite great therapeutic advancements in psoriasis, four notable difficult-to-treat areas including the scalp, nails, intertriginous (including genitals), and palmoplantar regions, pose a challenge to both physicians and patients. Localized disease of these specific body regions inflicts a significant burden on patients' quality of life and requires an adequate selection of treatments. Areas covered: This manuscript discusses appropriate therapies and important treatment considerations for these difficult-to-treat areas based on the available clinical data from the literature. Expert opinion: Clinical trials assessing therapies for the difficult-to-treat areas have been inadequate. With the first biological clinical trial for genital psoriasis pending publication, it is with hope that other biological agents will be evaluated for region-specific psoriasis. A greater understanding of the genetic and immunologic aspects of regional psoriasis, as well as identification of unique biomarkers, will further guide management decisions. For example, the recent discovery of the IL-36 receptor gene for generalized pustular psoriasis may prove valuable for other forms of psoriasis. Ultimately, identification of the most beneficial treatments for each psoriasis subtype and difficult-to-treat area will provide patients with maximal quality of life.

    2011-12-07

    Systemic hypotension is a relatively common complication of preterm birth and is associated with periventricular haemorrhage, periventricular white matter injury and adverse neurodevelopmental outcome. Corticosteroid treatment has been used as an alternative or an adjunct to conventional treatment with volume expansion and vasopressor/inotropic therapy. To determine the effectiveness and safety of corticosteroids used either as primary treatment of hypotension or for the treatment of refractory hypotension in preterm infants. Randomized or quasi-randomised controlled trials were identified by searching the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 2, 2011), MEDLINE (1996 to Jan 2011), EMBASE (1974 to Jan 2011), CINAHL (1981 to 2011), reference lists of published papers and abstracts from the Pediatric Academic Societies and the European Society for Pediatric Research meetings published in Pediatric Research (1995 to 2011). We included all randomised or quasi-randomised controlled trials investigating the effect of corticosteroid therapy in the treatment of hypotension in preterm infants (babies with hypotension resistant to inotropes/pressors and volume therapy. We included studies comparing oral/intravenous corticosteroids with placebo, other drugs used for providing cardiovascular support or no therapy in this review. Methodological quality of eligible studies was assessed according to the methods used for minimising selection bias, performance bias, attrition bias and detection bias. Studies that evaluated corticosteroids (1) as primary treatment for hypotension or (2) for refractory hypotension unresponsive to prior use of inotropes/pressors and volume therapy, were analysed using separate comparisons. Data were analysed using the standard methods of the Neonatal Review Group using Rev Man 5.1.2. Treatment effect was analysed using relative risk, risk reduction, number needed to treat for categorical outcomes and

  2. Carbon dioxide removal in gas treating processes

    International Nuclear Information System (INIS)

    Lidal, H.

    1992-06-01

    The main contribution of this work is the development of a simple and reliable modelling technique on carbon dioxide removal describing the vapor-liquid equilibria of CO 2 in aqueous alkanolamine solutions. By making use of measured pH data, the author has circumvented the problem of estimating interaction parameters, activity coefficients, and equilibrium constants in the prediction of vapor-liquid equilibria. The applicability of the model is best demonstrated on the tertiary amine system using MDEA. For this system, the VLE is accurately represented for temperatures in the range 25 to 140 o C, for CO 2 loadings from 0.001 to 1 mol/mol, and for amine molarities usually encountered in acid gas treating processes. The absorption of CO 2 into solutions containing the sterically hindered amine AMP, is also well described by the model. The equilibrium of CO 2 in mixed solvents containing a glycol (TEG,DEG) and an alkonolamine (MEA,DEA) has been measured at temperatures encountered in the absorption units. An equilibrium model has been developed for the CO 2 /TEG/MEA system for estimation of CO 2 partial pressures, covering loadings and temperatures for both absorption and desorption conditions. An important spin-off of the work described is that two new experimental set-ups have been designed and built. 154 refs., 38 figs., 22 tabs

    Tricuspid valve (TV) disease has been relatively neglected, despite the known association between severe tricuspid regurgitation (TR) and mortality. Few patients undergo isolated tricuspid surgery, which remains associated with high in-hospital mortality rates, particularly in patients with prior left-sided valve surgery. Patients with severe TR are often managed medically for years before TV repair or replacement. Current guidelines recommend TV repair in the presence of a dilated tricuspid annulus at the time of a left-sided valve surgical intervention, even if regurgitation is mild. This proposed algorithm aims to prevent the inevitable progression to severe TR and the need for a second surgical intervention. Recently, novel transcatheter treatment options were developed for treating patients with severe TR and right heart failure with prohibitive surgical risk. Here we describe currently available transcatheter treatment options for severe TR implanted at different levels: the junction between vena cavae and right atrium; the tricuspid annulus; or between TV leaflets, improving coaptation.

  4. Do we over treat mild hypertension?

    Science.gov (United States)

    Zanchetti, Alberto

    2015-06-01

    The important question whether 'mild' hypertension should or should not be treated by drugs is difficult to answer, because the only randomized controlled trials (RCTs) investigating this question were conducted when the definition of 'mild' hypertension was based on diastolic blood pressure only, whereas the present definition of grade 1 hypertension includes both systolic and diastolic values (SBP/DBP), and the concept of 'mild' hypertension also includes that of low-moderate cardiovascular risk (hypertension only on the basis of expert opinion. However, recent meta-analyses have provided some support to drug treatment intervention in low-moderate risk grade 1 hypertensives and have shown that, when treatment is deferred until organ damage or cardiovascular disease occur, absolute residual risk (events occurring despite treatment) markedly increases. Although evidence favoring therapeutic intervention in mild hypertension is nowadays stronger than expert opinion, meta-analyses are not substitutes for specific RCTs, and the wide BP spans defining grade 1 hypertension as well as the span defining low-moderate risk leave a wide space for individualized or personalized decisions.

    2015-06-01

    Full Text Available Purpose: We report a case of a foveal macroaneurysm with long-standing macular edema in a rare location, successfully treated with intravitreal ranibizumab. Methods: We report the case of a 52-year-old man with left eye long-term visual loss due to macular edema caused by a retinal macroaneurysm, localized about 400 μm from the center of the fovea, and its response to 6 monthly ranibizumab intravitreal injections. His best-corrected visual acuity and morphological data evaluated by optical coherence tomography and fluorescein angiography are presented. Results: His best-corrected visual acuity improved from 1/10 to 3/10 after the 3rd injection, and from 1/10 to 4/10 after the 6th one. The central retinal thickness was evaluated by optical coherence tomography and improved from 310 to 233 μm, with the resolution of both the associated serous detachments and the cystoid macular edema; an almost complete reabsorption of the hard exudates at the end of the treatment was also observed. The macroaneurysm lumen almost obliterated after the 3rd injection and completely collapsed at the end of treatment. Conclusions: Intravitreal ranibizumab may be effective in the treatment of long-standing macular edema associated with foveal macroaneurysms. To the best of our knowledge, this is the first report of a retinal macroaneurysm located so close to the foveal avascular zone.

  6. Adapting craniosacral therapy to treat horses

    2017-01-01

    Full Text Available Craniosacral therapy is an acknowledged therapeutic method used for treating humans. It derives from osteopathy, being a manual technique which uses a very gentle touch. It consists in balancing the fluctuation of cerebrospinal fluid by applying appropriate holds that make it possible for the patientŐs organism to release tensions which have formed in tissues. The aim of the present work was to depict the possibility to adapt the method of craniosacral therapy used in humans to the therapy of horses. Thirteen therapeutic holds proposed for the treatment of horses were described and interpreted graphically on the basis of therapy of 62 horses with different disorders. A total of 241 craniosacral therapy treatments were performed. The adaptation of presented craniosacral therapy holds to equine therapy was developed by the first author on the basis of relevant holds used in the biodynamic craniosacral therapy in humans and in own therapeutic practice. The effects of own practice and data available in literature suggest that craniosacral therapy seems to be an effective method of improving the state of health of horses suffering from different complaints that may cause major difficulties in sport, breeding or private use of the animals. The use of thermography made it possible to record the effects of therapy and some processes accompanying it, which had been impossible before.

    2017-08-03

    The 2016 revision of the World Health Organization (WHO) classification for lymphoma has included a new category of lymphoma, separate from diffuse large B-cell lymphoma, termed high-grade B-cell lymphoma with translocations involving myc and bcl-2 or bcl-6 . These lymphomas, which occur in hit lymphomas (or triple-hit lymphomas if all 3 rearrangements are present). It is important to differentiate these lymphomas from the larger group of double-expressor lymphomas, which have increased expression of MYC and BCL-2 and/or BCL-6 by immunohistochemistry, by using variable cutoff percentages to define positivity. Patients with double-hit lymphomas have a poor prognosis when treated with standard chemoimmunotherapy and have increased risk of central nervous system involvement and progression. Double-hit lymphomas may arise as a consequence of the transformation of the underlying indolent lymphoma. There are no published prospective trials in double-hit lymphoma, however retrospective studies strongly suggest that aggressive induction regimens may confer a superior outcome. In this article, I review my approach to the evaluation and treatment of double-hit lymphoma, with an eye toward future clinical trials incorporating rational targeted agents into the therapeutic armamentarium. © 2017 by The American Society of Hematology.

    The aim of the study is to determine environmentally friendlier construction materials for constructed wetland facilities treating wastewater. This is done by computing the environmental footprint of the facility based on the methodology of life cycle assessment (LCA). This methodology reveals the dominant aggravating processes during the construction of a constructed wetland (CW) and can help to create alternative environmentally friendlier solutions. This methodology was applied for the determination of the overall environmental profile of a hybrid CW facility. The LCA was applied first to the facility as originally designed, where reinforced concrete was used in some components. Then, alternative construction materials to reinforced concrete were used, such as earth covered with high density polyethylene (HDPE) or clay, and LCA was applied again. Earth structures were found to have reduced environmental impact compared to concrete ones, and clay was found environmentally friendlier compared to HDPE. Furthermore, estimation of the construction costs of the three scenarios indicate that the last scenario is also the least expensive.

  9. How I treat CLL up front.

    2010-01-14

    Although chronic lymphocytic leukemia (CLL) remains incurable, over the past decade there have been major advances in understanding the pathophysiology of CLL and in the treatment of this disease. This has led to greatly increased response rates and durations of response but not yet improved survival. Advances in the use of prognostic factors that identify patients at high risk for progression have led us to the question whether there is still a role for a "watch and wait" approach in asymptomatic high-risk patients or whether they should be treated earlier in their disease course. Questions remain, including, what is the optimal first-line treatment and its timing and is there any role of maintenance therapy or stem cell transplantation in this disease? CLL is a disease of the elderly and not all patients are eligible for aggressive up-front chemoimmunotherapy regimens, so what is the optimal treatment approach for more frail elderly patients? It is highly likely that our treatment approaches will continue to evolve as the results of ongoing clinical trials are released and that further improvements in the outcome of this disease will result from identification of therapies that target the underlying pathophysiology of CLL.

  10. Carbon dioxide removal in gas treating processes

    Energy Technology Data Exchange (ETDEWEB)

    Lidal, H

    1992-06-01

    The main contribution of this work is the development of a simple and reliable modelling technique on carbon dioxide removal describing the vapor-liquid equilibria of CO{sub 2} in aqueous alkanolamine solutions. By making use of measured pH data, the author has circumvented the problem of estimating interaction parameters, activity coefficients, and equilibrium constants in the prediction of vapor-liquid equilibria. The applicability of the model is best demonstrated on the tertiary amine system using MDEA. For this system, the VLE is accurately represented for temperatures in the range 25 to 140{sup o}C, for CO{sub 2} loadings from 0.001 to 1 mol/mol, and for amine molarities usually encountered in acid gas treating processes. The absorption of CO{sub 2} into solutions containing the sterically hindered amine AMP, is also well described by the model. The equilibrium of CO{sub 2} in mixed solvents containing a glycol (TEG,DEG) and an alkonolamine (MEA,DEA) has been measured at temperatures encountered in the absorption units. An equilibrium model has been developed for the CO{sub 2}/TEG/MEA system for estimation of CO{sub 2} partial pressures, covering loadings and temperatures for both absorption and desorption conditions. An important spin-off of the work described is that two new experimental set-ups have been designed and built. 154 refs., 38 figs., 22 tabs.

    2001-01-01

    To evaluate prognostic factors affecting surgically treated osteoradionecrosis (ORN) of the mandible, 13 patients with mandibular bone necrosis caused by irradiation for head and neck cancer were examined chlinicopathologically. The subjects were included 12 men and 1 woman, with a mean age of 65.3 years at surgery. The mean total dose of irradiation was 61.6 Gy. The clinical stage according to Epstein et al. (1987) was IIB in 1 patient, IIIA in 4, and IIIB in 8. The mandible was resected 10 mm or more from the lesion. Delayed healing was found in two patients, and three had recurrence of necrosis of the remaining bone. Patients whose mandibular periosteum had been resected previously who received mandibular reconstruction had a poor outcome. Pathological changes, such as stenosis of the inferior alveolar artery, fibrosis of bone marrow, and low osteocyte density in cortical bone, were found in all resected mandibles. Among them, mandibles lacking sequestra and bone remodeling had poor viability. Therefore, the periosteal blood supply should be conserved and surgical interventions, particularly heat, must be minimized to avoid recurrence of ORN. (author)

    Adenocystic carcinoma most commonly develops in the major salivary glands, on the other hand it is rare for adenocystic carcinoma to develop in the larynx. We report a case of adenocystic carcinoma in the larynx. A 54-year-old male was hospitalized with symptoms of hoarseness and dyspnea on exertion. He presented a tumor that developed at the base of the right arytenoid, and covered over the glottis. It was confirmed to be adenocystic carcinoma (solid type) by biopsy. Positron emission tomography (PET)-CT also revealed a left cervical lymph node metastasis and multiple pulmonary metastases (T1N2cM1). He was treated with proton therapy to the larynx to prevent airway obstruction by growth of the tumor and to preserve the larynx because he had uncontrollable pulmonary metastasis. Although the tumor vanished after the treatment, one month later he had halitosis, dyspnea and bilateral vocal cord palsy. Despite administration of an antibacterial drug and steroid, there was no improvement to the narrowness of the glottis. A tracheotomy was therefore performed three months after the proton therapy. PET-CT, which was performed after the tracheotomy, suggested growth of the residual tumor or laryngeal radionecrosis. This study confirmed that proton therapy is effective for adenocystic carcinoma in the larynx. However, proton therapy also was found to cause laryngeal radionecrosis. These results indicate the importance of evaluating the side effects of radiation therapy and providing that information to the patient. (author)

    2004-06-01

    To review the etiology, treatment, and preventive strategies of hyperuricemia and gout in kidney transplant recipients. Primary literature was obtained via Medline (1966-June 2003). Studies evaluating treatment and prevention of hyperuricemia and gout in kidney transplantation were considered for evaluation. English-language studies were selected for inclusion. Approximately 14,000 kidney transplantations were performed in the United States in 2003, and of those transplant recipients, nearly 13% will experience a new onset of gout. The prevalence of hyperuricemia is even greater. There are several mechanisms by which hyperuricemia and gout develop in kidney transplant recipients. Medication-induced hyperuricemia and renal dysfunction are 2 of the more common mechanisms. Prophylactic and treatment options include allopurinol, colchicine, corticosteroids, and, if absolutely necessary, nonsteroidal antiinflammatory drugs. It is generally recommended to decide whether the risks of prophylactic therapy and treatment outweigh the benefits. Often, the risk of adverse events associated with agents to treat these ailments tends to outweigh the benefits; therefore, treatment is usually reserved for symptomatic episodes of acute gout. Practitioners must also decide if changes in immunosuppressive regimens may be of benefit on a patient-by-patient basis.

    The objective of this audit was to evaluate the impact of brief educational intervention on prompt recognition and treatment of pain in the emergency department. The audit was performed on all patients in the emergency department with pain presenting over a 24-h period on three occasions: preintervention, 1-week postintervention and at 4 months. In 151 patients, pain severity scores were mild (24%), moderate (42%), severe (16%) and unknown (18%). Pain score documentation at triage improved from 72 to 94% during the audit (P = 0.01). There was no significant difference in the number of patients treated within 20 min for severe pain (P = 0.076) and within 60 min for moderate pain (P = 0.796) between audits. The likelihood of receiving analgesia within 20 min increased with the patients\\' pain category (relative risk: 1.8 95% confidence interval: 1.4-2.3). Documentation of pain assessment and the use of pain scores at triage improved after a brief educational intervention but there was no measurable impact on treatment times.

  15. Method of treating radioactive sludge waste

    1989-01-01

    For removing water content from sludge wastes, filtration or steam condensation may be considered, but none of them can sufficiently reduce the water content since filtration may cause clogging and steam treatment has a limit in the condensation. In view of the above, radioactive sludge wastes are dehydrated by an electroosmotic process in a vessel and then dehydrated solid contents are solidified in the vessel. Since the sludge wastes are mainly composed o fion exchange resins and iron oxides deposited to the resins, when a DC voltage is applied to the sludges containing such solid contents, a force tending to premeate them through the fine pores in the filter is exerted to water. As a result, only water is removed while the solids are being held on the filters. Since the moving direction of water is different depending on the property of the sludges, the polarity of the electrodes may be changed depending on the nature of the sludges. Thus, volume reduction can be improved and treating conditions can be controlled easily by a simple device. (N.H.)

    Full Text Available A case of a canine oral eosinophilic granuloma in a 14-year-old female crossbred is described. The dog was presented with a history of ptyalism, halitosis, local pain, decreased appetite, and blood staining noted on food and water bowls. Clinical, hematologic, and biochemical examinations, abdominal ultrasonography, and 3-view chest radiographs were performed, and no metastases were found. Histopathologic examination of two 6 mm punch biopsies from the oral lesion revealed the presence of eosinophilic granulomatous lesions in the submucosa. After treatment with corticosteroids and wide spectrum antibiotics no significant changes in clinical signs and lesion size were observed. Electrochemotherapy (ECT, a novel tumor treatment routinely used for cutaneous and subcutaneous tumors in human patients in the European Union since 2006, was used to treat the eosinophilic granuloma. The procedure was performed under general anesthesia, followed by intravenous administration of bleomycin. Six weeks after treatment a complete response with disappearance of the mass and improvement of clinical signs were observed.

    To increase the heat and salt resistance of a wash fluid, monoethanolamine processed waste of licorice production - grist in a volume of 5-8% by weight, is introduced into it as the disperse phase. The processing of the grist is conducted for 1-2 hours at 20-100/sup 0/C and the volume of the monoethanolamine is 0.05-0.1% by weight. The properties of the washing fluids treated by the grist with the introduction of 20% CaC1/sub 2/ into them were not deteriorated, while complete coagulation was achieved with its introduction into washing fluids on the basis of KMTs. Grist washing liquids do not deteriorate their own properties to a temperature of 200/sup 0/C, do not cause equipment corrosion, are inert to swelling clay rocks and with the introduction of KMTs at a temperature above 130-140/sup 0/C cause insignificant destruction of the reagent which is accompanied by a change in the color of the solutions and a drop in the degree of polymerization and viscosity.

    Before extraction and synthetic chemistry were invented, musculoskeletal complaints were treated with preparations from medicinal plants. They were either administered orally or topically. In contrast to the oral medicinal plant products, topicals act in part as counterirritants or are toxic when given orally. To update the previous Cochrane review of herbal therapy for osteoarthritis from 2000 by evaluating the evidence on effectiveness for topical medicinal plant products. Databases for mainstream and complementary medicine were searched using terms to include all forms of arthritis combined with medicinal plant products. We searched electronic databases (Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, AMED, CINAHL, ISI Web of Science, World Health Organization Clinical Trials Registry Platform) to February 2013, unrestricted by language. We also searched the reference lists from retrieved trials. Randomised controlled trials of herbal interventions used topically, compared with inert (placebo) or active controls, in people with osteoarthritis were included. Two review authors independently selected trials for inclusion, assessed the risk of bias of included studies and extracted data. Seven studies (six different medicinal plant interventions; 785 participants) were included. Single studies (five studies) and non-comparable studies (two studies) precluded pooling of results.Moderate evidence from a single study of 174 people with hand osteoarthritis indicated that treatment with Arnica extract gel probably results in similar benefits as treatment with ibuprofen (non-steroidal anti-inflammatory drug) with a similar number of adverse events. Mean pain in the ibuprofen group was 44.2 points on a 100 point scale; treatment with Arnica gel reduced the pain by 4 points after three weeks: mean difference (MD) -3.8 points (95% confidence intervals (CI) -10.1 to 2.5), absolute reduction 4% (10% reduction to 3% increase). Hand function was 7

    Caffeine, a methilxantine drug is a component of coffee, tea, stimulants and other drinks. Caffeine inhibits phosphodiesterase leading to intracellular accumulation of cyclic AMP, blocks adenosine receptors, and increases the release of Ca 2+ . We have studied the possible effect of caffeine in DNA plasmid treated or not with stannous chloride (SnCl 2 ). Previous evaluations of the effect of caffeine on the labeling of red blood cells and plasma proteins with technetium-99m have showed a decrease of % ATI in the insoluble fraction of plasma proteins. Samples of DNA were treated with SnCl 2 (0 and 200μg/ml) in 0.8% agarose. SnCl 2 has induced break on DNA and caffeine has not showed effect on the DNA. This indicates that caffeine does not eliminate the oxidant action of SnCl 2 and does not promote break in isolated DNA plasmid. (author)

    When deprived of nutrients, spore forming bacilli produce endospores which are remarkably resistant to chemical sterilization. Little is known about the morphology and response fo these spores following exposure to sporocidal agents. Light microscopy does not provide sufficient resolution for studying the rupture of the spore coat and fate of intracellular material. Transmission and scanning electron microscopy offer superior resolution but require specimen preparation methods that induce physiologic as well as morphologic changes in the spores, thereby making accurate interpretation of micrographs difficult. To eliminate the possible artifacts induced by chemical fixation, dehydration, embeddment, staining and sectioning, treated and non-sporocide-treated endospores of B. thuringiensis and B. subtilis were imaged by x-ray contact microscopy using monochromatic x-rays. 6 refs., 2 figs

    The purpose of this study was to report the MRI findings that can be encountered in successfully treated bacterial septic arthritis. The study included 12 patients (8 male and 4 female; mean age 38 years, range 9-85) with 13 proven cases of bacterial septic arthritis. The joints involved were hip (n = 3), knee (n = 3), shoulder (n = 2), sacroiliac (n = 2), ankle (n = 1), wrist (n = 1), and elbow (n = 1). MRI examinations following surgical debridement and at initiation of antibiotic therapy and after successful treatment were compared for changes in effusion, synovium, bone, and periarticular soft tissues. Imaging findings were correlated with microbiological and clinical findings. Joint effusions were present in all joints at baseline and regressed significantly at follow-up MRI (p = 0.001). Abscesses were present in 5 cases (38 %), and their sizes decreased significantly at follow-up (p = 0.001). Synovial enhancement and thickening were observed in all joints at both baseline and follow-up MRI. Myositis/cellulitis was present in 10 cases (77 %) at baseline and in 8 cases (62 %) at follow-up MRI. Bone marrow edema was present in 10 joints (77 %) at baseline and persisted in 8 joints (62 %). Bone erosions were found in 8 joints (62 %) and persisted at follow-up MRI in all cases. The sizes of joint effusions and abscesses appear to be the factors with the most potential for monitoring therapy for septic arthritis, since both decreased significantly following successful treatment. Synovial thickening and enhancement, periarticular myositis/cellulitis, and bone marrow edema can persist even after resolution of the infection. (orig.)

    When oral rehydration is not feasible, enteral rehydration via the nasogastric route has been the ESPGHAN recommended method of rehydration since 2008, rather than intravenous rehydration (IVR), for children with acute gastroenteritis. However, these recommendations are rarely followed in France. Since 2011, in case of failure of oral rehydration, enteral rehydration has been used as a first-line therapy in the Children's Emergency Department at the Grenoble-Alpes University Hospital. The aims of the study were to compare the length of the hospital stay, the duration of initial rehydration, and the incidence of complications and failure with the use of enteral nasogastric versus intravenous rehydration. This study compared two cohorts of children (rehydration via the oral route. The first group (winter 2010-2011) was managed according to the previous protocol (intravenous rehydration). The second group (winter 2011-2012) was managed according the new protocol (nasogastric tube rehydration [NGR]). The rest of the gastroenteritis management was identical in both groups. A total of 132 children were included, 65 were treated with nasogastric tube rehydration (NGR) and 67 with intravenous rehydration. There was a significant reduction in the duration of hospitalization in the post-emergency unit in the NGR group: 23.6h vs 40.1h (Prehydration was also significantly reduced (10.5h vs 22.0h). There was no significant difference regarding serious adverse events. However, the NGR group presented more mild adverse events (22 vs 7, Prehydration reduces the duration of rehydration and the length of the hospital stay without increasing the incidence of serious adverse events for dehydrated children hospitalized for acute gastroenteritis.

    The purpose of this study was to compare the use of an intravitreal injection of infliximab and of dexamethasone combined with vancomycin to treat experimental endophthalmitis induced by Staphylococcus epidermidis. The study was conducted between March 25 and April 13, 2012. Twenty-five six-month-old healthy rabbits were used, each weighing 2.5-3 kg. The rabbits were randomized into five groups with five animals per group. Endophthalmitis was induced by 0.1 mL (103 colony-forming units) S. epidermidis in all groups. In group 1, injection was not implemented after the occurrence of endophthalmitis. In groups 2, 3, and 4, the following intravitreal injections were given 24 h after the occurrence of endophthalmitis: group 2, 0.1 mg/0.1 mL vancomycin; group 3, 1 mg/0.1 mL vancomycin and 1 mg/0.1 mL dexamethasone; and group 4, 1 mg/0.1 mL vancomycin and 2 mg/0.1 mL infliximab. Group 5 was the control/uninfected group. The rabbits were clinically assessed each day for seven days. On day 9, a histopathologic evaluation was performed after enucleation. After a clinical evaluation, no statistically significant difference was found between the vancomycin+infliximab and vancomycin+dexamethasone groups (p>0.05). The difference was significant when both groups were compared with the vancomycin group (p0.05). An intravitreal injection of infliximab and of dexamethasone combined with vancomycin have similar clinical and histopathologic effects. To supplement the antibiotic treatment of endophthalmitis, infliximab in a safe dose range can be used as an alternative to dexamethasone to suppress inflammation and prevent ocular damage.

    Recently published studies show that the prevalence of polyneuropathy (PNP) is higher in patients with Parkinson's disease (PD) than in age-matched controls. Its pathogenesis, however is a matter of controversy. The major hypothesis is the toxicity of high concentrations of homocysteine (Hcy) possibly related to levodopa (LD) therapy. The aim of the present study was to determine the prevalence of PNP, independent of other etiologies, and to determine the relationship to demographic and clinical factors in LD-treated Parkinson's patients. A total of 102 patients (51 patients with PD and 51 sex- and age-matched healthy controls) were enrolled in the study. The presence of any risk factors for PNP, ascertained from the history and laboratory tests, was an exclusion criterion. The Toronto Clinical Scoring System (TCSS) was used for clinical assessment of PNP. The objective assessment was based on electroneurography (ENG) studies in which motor nerves (peroneal and tibial nerves) as well as sensory nerves (sural and superficial peroneal nerves) were bilaterally examined. The severity of the disease was determined using the UPDRS scale (Unified Parkinson's Disease Rating Scale) and the Hoehn-Yahr (H-Y) scale. In the PD group, the clinical and neurophysiological indicators of PNP, manifested as a symmetrical and predominantly sensory axonal neuropathy, were more frequent then in the control group and observed in 43.1% vs. 13.7% and 15.7% vs. 2% of subjects respectively. The presence of PNP correlated with age and the severity of PD. Patients with PD and PNP had a higher level of Hcy as compared to PD patients without PNP, however the difference was not statistically significant. The frequency of PNP in PD patients is higher than in controls. The characteristics and discrepancy between the number of patients with clinical and ENG detected PNP may suggest the small fiber neuropathy (SFN) as the dominant form of neuropathy in PD patients.

    Pressure ulcers, also known as pressure injuries and bed sores, are localised areas of injury to the skin or underlying tissues, or both. Dressings made from a variety of materials, including foam, are used to treat pressure ulcers. An evidence-based overview of dressings for pressure ulcers is needed to enable informed decision-making on dressing use. This review is part of a suite of Cochrane Reviews investigating the use of dressings in the treatment of pressure ulcers. Each review will focus on a particular dressing type. To assess the clinical and cost effectiveness of foam wound dressings for healing pressure ulcers in people with an existing pressure ulcer in any care setting. In February 2017 we searched: the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL); Ovid MEDLINE (including In-Process & Other Non-Indexed Citations); Ovid Embase; EBSCO CINAHL Plus and the NHS Economic Evaluation Database (NHS EED). We also searched clinical trials registries for ongoing and unpublished studies, and scanned reference lists of relevant included studies as well as reviews, meta-analyses and health technology reports to identify additional studies. There were no restrictions with respect to language, date of publication or study setting. Published or unpublished randomised controlled trials (RCTs) and cluster-RCTs, that compared the clinical and cost effectiveness of foam wound dressings for healing pressure ulcers (Category/Stage II or above). Two review authors independently performed study selection, risk of bias and data extraction. A third reviewer resolved discrepancies between the review authors. We included nine trials with a total of 483 participants, all of whom were adults (59 years or older) with an existing pressure ulcer Category/Stage II or above. All trials had two arms, which compared foam dressings with other dressings for treating pressure ulcers.The certainty of evidence ranged from low to very low due

    Tobacco smoking is the leading cause of preventable deaths worldwide, but many smokers are simply unable to quit. Psychosocial and pharmaceutical treatments have shown modest results on smoking cessation rates, but there is an urgent need to develop treatments with greater efficacy. Brain stimulation methods are gaining increasing interest as possible addiction therapeutics. The purpose of this paper is to review the studies that have evaluated brain stimulation techniques on tobacco addiction, and discuss future directions for research in this novel area of addiction interventions. Electronic and manual literature searches identified fifteen studies that administered repetitive transcranial magnetic stimulation (rTMS), cranial electrostimulation (CES), transcranial direct current stimulation (tDCS) or deep brain stimulation (DBS). rTMS was found to be the most well studied method with respect to tobacco addiction. Results indicate that rTMS and tDCS targeted to the dorsolateral prefrontal cortex (DLPFC) were the most efficacious in reducing tobacco cravings, an effect that may be mediated through the brain reward system involved in tobacco addiction. While rTMS was shown to reduce consumption of cigarettes, as yet no brain stimulation technique has been shown to significantly increase abstinence rates. It is possible that the therapeutic effects of rTMS and tDCS may be improved by optimization of stimulation parameters and increasing the duration of treatment. Although further studies are needed to confirm the ability of brain stimulation methods to treat tobacco addiction, this review indicates that rTMS and tDCS both represent potentially novel treatment modalities.

    At least one third of patients with active epilepsy suffer from significant impairment of their emotional well-being. A targeted examination for possible depression (irrespective of any social, financial or personal burdens) can identify patients who may benefit from medical attention and therapeutic support. Reliable screening instruments such as the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E) are suitable for the timely identification of patients needing help. Neurologists should be capable of managing mild to moderate comorbid depression but referral to mental health specialists is mandatory in severe and difficult-to-treat depression, or if the patient is acutely suicidal. In terms of the therapeutic approach, it is essential first to optimize seizure control and minimize unwanted antiepileptic drug-related side effects. Psychotherapy for depression in epilepsy (including online self-treatment programs) is underutilized although it has proven effective in ten well-controlled trials. In contrast, the effectiveness of antidepressant drugs for depression in epilepsy is unknown. However, if modern antidepressants are used (e.g. SSRI, SNRI, NaSSA), concerns about an aggravation of seizures and or problematic interactions with antiepileptic drugs seem unwarranted. Epilepsy-related stress ("burden of epilepsy") explains depression in many patients but acute and temporary seizure-related states of depression or suicidality have also been reported. Limbic encephalitits may cause isolated mood alteration without any recognizable psychoetiological background indicating a possible role of neuroinflammation. This review will argue that, overall, a bio-psycho-social model best captures the currently available evidence relating to the etiology and treatment of depression as a comorbidity of epilepsy.

    The purpose of this study was to report the MRI findings that can be encountered in successfully treated bacterial septic arthritis. The study included 12 patients (8 male and 4 female; mean age 38 years, range 9-85) with 13 proven cases of bacterial septic arthritis. The joints involved were hip (n = 3), knee (n = 3), shoulder (n = 2), sacroiliac (n = 2), ankle (n = 1), wrist (n = 1), and elbow (n = 1). MRI examinations following surgical debridement and at initiation of antibiotic therapy and after successful treatment were compared for changes in effusion, synovium, bone, and periarticular soft tissues. Imaging findings were correlated with microbiological and clinical findings. Joint effusions were present in all joints at baseline and regressed significantly at follow-up MRI (p = 0.001). Abscesses were present in 5 cases (38 %), and their sizes decreased significantly at follow-up (p = 0.001). Synovial enhancement and thickening were observed in all joints at both baseline and follow-up MRI. Myositis/cellulitis was present in 10 cases (77 %) at baseline and in 8 cases (62 %) at follow-up MRI. Bone marrow edema was present in 10 joints (77 %) at baseline and persisted in 8 joints (62 %). Bone erosions were found in 8 joints (62 %) and persisted at follow-up MRI in all cases. The sizes of joint effusions and abscesses appear to be the factors with the most potential for monitoring therapy for septic arthritis, since both decreased significantly following successful treatment. Synovial thickening and enhancement, periarticular myositis/cellulitis, and bone marrow edema can persist even after resolution of the infection. (orig.)

    Gonorrhoea is a sexually transmitted infection that is caused by Neisseria gonorrhoeae, and is a major public health challenge today. N gonorrhoeae can be transmitted from the mother's genital tract to the newborn during birth, and can cause gonococcal ophthalmia neonatorum as well as systemic neonatal infections. It can also cause endometritis and pelvic sepsis in the mother. This review updates and replaces an earlier Cochrane Review on antibiotics for treating this infectious condition. To assess the clinical effectiveness and harms of antibiotics for treating gonorrhoea in pregnant women. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 May 2017), LILACS database (1982 to April 5, 2017), the WHO International Clinical Trials Registry Platform (ICTRP; April 5, 2017), ClinicalTrials.gov (April 5, 2017), the ISRCTN Registry (April 5, 2017), and Epistemonikos (April 5, 2017). We also searched reference lists of all retrieved articles. We included randomised controlled trials (RCTs) comparing the use of antibiotics for treating gonorrhoea in pregnancy. The antibiotics could have been used alone or in combination, were administered parenterally, orally, or both, and were compared with another antibiotic.We included RCTs regardless of their publication status (published, unpublished, published as an article, an abstract, or a letter), language, or country. We applied no limits on the length of follow-up.We excluded RCTs using a cluster- or cross-over design, or quasi-RCTs. Three review authors independently assessed trials for inclusion and risk of bias, extracted data, and checked them for accuracy. We included two RCTs, that randomised 514 pregnant women (347 women analysed) at a mean gestational age of 22 weeks. Both trials were conducted in the outpatient department of the same two hospitals in the USA between 1993 and 2001, and had a follow-up of 14 days. One of the trials was sponsored by a drug company. We considered both trials to

    Background In developing countries, diarrhoea causes around 500,000 child deaths annually. Zinc supplementation during acute diarrhoea is currently recommended by the World Health Organization (WHO) and the United Nations Children's Fund (UNICEF). Objectives To evaluate oral zinc supplementation for treating children with acute or persistent diarrhoea. Search methods We searched the Cochrane Infectious Diseases Group Specialized Register, CENTRAL (the Cochrane Library 2016, Issue 5), MEDLINE, Embase, LILACS, CINAHL, mRCT, and reference lists up to 30 September 2016. We also contacted researchers. Selection criteria Randomized controlled trials (RCTs) that compared oral zinc supplementation with placebo in children aged one month to five years with acute or persistent diarrhoea, including dysentery. Data collection and analysis Both review authors assessed trial eligibility and risk of bias, extracted and analysed data, and drafted the review. The primary outcomes were diarrhoea duration and severity. We summarized dichotomous outcomes using risk ratios (RR) and continuous outcomes using mean differences (MD) with 95% confidence intervals (CI). Where appropriate, we combined data in meta-analyses (using either a fixed-effect or random-effects model) and assessed heterogeneity. We assessed the certainty of the evidence using the GRADE approach. Main results Thirty-three trials that included 10,841 children met our inclusion criteria. Most included trials were conducted in Asian countries that were at high risk of zinc deficiency. Acute diarrhoea There is currently not enough evidence from well-conducted RCTs to be able to say whether zinc supplementation during acute diarrhoea reduces death or number of children hospitalized (very low certainty evidence). In children older than six months of age, zinc supplementation may shorten the average duration of diarrhoea by around half a day (MD −11.46 hours, 95% CI −19.72 to −3.19; 2581 children, 9 trials, low

  17. Medical Devices Assess, Treat Balance Disorders

    You may have heard the phrase as difficult as walking and chewing gum as a joking way of referring to something that is not difficult at all. Just walking, however, is not all that simple physiologically speaking. Even standing upright is an undertaking requiring the complex cooperation of multiple motor and sensory systems including vision, the inner ear, somatosensation (sensation from the skin), and proprioception (the sense of the body s parts in relation to each other). The compromised performance of any of these elements can lead to a balance disorder, which in some form affects nearly half of Americans at least once in their lifetimes, from the elderly, to those with neurological or vestibular (inner ear) dysfunction, to athletes with musculoskeletal injuries, to astronauts returning from space. Readjusting to Earth s gravity has a significant impact on an astronaut s ability to balance, a result of the brain switching to a different "model" for interpreting sensory input in normal gravity versus weightlessness. While acclimating, astronauts can experience headaches, motion sickness, and problems with perception. To help ease the transition and study the effects of weightlessness on the body, NASA has conducted many investigations into post-flight balance control, realizing this research can help treat patients with balance disorders on Earth as well. In the 1960s, the NASA-sponsored Man Vehicle Laboratory at the Massachusetts Institute of Technology (MIT) studied the effects of prolonged space flight on astronauts. The lab s work intrigued MIT doctoral candidate Lewis Nashner, who began conducting NASA-funded research on human movement and balance under the supervision of Dr. Larry Young in the MIT Department of Aeronautics and Astronautics. In 1982, Nashner s work resulted in a noninvasive clinical technique for assessing the cooperative systems that allow the body to balance, commonly referred to as computerized dynamic posturography (CDP). CDP employs a

    In human medicine, psychiatric side effects among patients on corticosteroid therapy are widely reported, but this appears to have been largely overlooked in the animal literature despite glucocorticoids being widely used in veterinary medicine. Therefore the aim of the current study was to identify possible psycho-behavioural changes in dogs treated with corticosteroids. Two different methodologies were used. Firstly, dog owners were asked to fill a 12 item questionnaire aimed at further validating the initial results of a previous survey relating to changes seen when their dog was receiving corticosteroid treatment. In a second study, a population of dogs undertook behavioural tests aimed at objectively identifying changes when receiving corticosteroid therapy. In the first study, a sample of owners whose dogs were receiving treatment for dermatological, orthopaedic or other conditions evaluated their dogs' behaviour on and off therapy, using a seven point scale. The survey was completed by 44 dog owners with dogs receiving treatment with a range of corticosteroid preparations (mainly prednisolone and methylprednisolone) and 54 dog owners with dogs receiving treatment with other drugs, mainly antibiotics and non-steroidal anti-inflammatory drugs. Dogs under corticosteroid treatment were reported to be significantly less playful, more nervous/restless, more fearful/less confident, more aggressive in the presence of food, more prone to barking, more prone to startle, more prone to reacting aggressively when disturbed, and more prone to avoiding people or unusual situations. In the second study, eleven “treatment” dogs were tested both before and during corticosteroid treatment with either methyl-prednisolone or prednisolone to assess their sensitivity to a potentially aversive sound stimulus. Eleven control dogs were also tested at the same time intervals in the same environment. Dogs were exposed to a brief dog growl while they explored bowls containing food

    This study analyzed the relationship in orthodontically treated adults between upper central incisor displacement measured on lateral cephalograms and apical root resorption measured on anterior periapical x-ray films. A multiple linear regression examined incisor displacements in four directions (retraction, advancement, intrusion, and extrusion) as independent variables, attempting to account for observed differences in the dependent variable, resorption. Mean apical resorption was 1.36 mm (sd +/- 1.46, n = 73). Mean horizontal displacement of the apex was -0.83 mm (sd +/- 1.74, n = 67); mean vertical displacement was 0.19 mm (sd +/- 1.48, n = 67). The regression coefficients for the intercept and for retraction were highly significant; those for extrusion, intrusion, and advancement were not. At the 95% confidence level, an average of 0.99 mm (se = +/- 0.34) of resorption was implied in the absence of root displacement and an average of 0.49 mm (se = +/- 0.14) of resorption was implied per millimeter of retraction. R2 for all four directional displacement variables (DDVs) taken together was only 0.20, which implied that only a relatively small portion of the observed apical resorption could be accounted for by tooth displacement alone. In a secondary set of univariate analyses, the associations between apical resorption and each of 14 additional treatment-related variables were examined. Only Gender, Elapsed Time, and Total Apical Displacement displayed statistically significant associations with apical resorption. Additional multiple regressions were then performed in which the data for each of these three statistically significant variables were considered separately, with the data for the four directional displacement variables. The addition of information on Elapsed Time or Total Apical Displacement did not explain a significant additional portion of the variability in apical resorption. On the other hand, the addition of information on Gender to the

    In 2010, the American Diabetes Association (ADA) proposed that individuals with fasting glucose level of 100-125 mg/dL (5.6-6.9 mmol/L) or glucose level of 140-199 mg/dL (7.8-11.0 mmol/L) 2 hours after a 75-g oral glucose tolerance test or hemoglobin A(1c) 5.7%-6.4% be classified as prediabetic, indicating increased risk for the emergence of diabetes mellitus. At the same time, the ADA formulated guidelines for the use of metformin for the treatment of prediabetes. To determine the prevalence of prediabetes in a cohort of psychiatrically ill adults receiving antipsychotics and to compare the clinical and metabolic features of prediabetic patients with those of patients with normal glucose tolerance and those with diabetes mellitus. The 2010 ADA criteria were applied to a large, consecutive, single-site European cohort of 783 adult psychiatric inpatients (mean age: 37.6 years) without a history of diabetes who were receiving antipsychotics. All patients in this cross-sectional study underwent measurement of body mass index (BMI), waist circumference, oral glucose tolerance test, and fasting insulin and lipids from November 2003 through July 2007. 413 patients (52.8%) had normal glucose tolerance, 290 (37.0%) had prediabetes, and 80 (10.2%) had diabetes mellitus. The fasting glucose and/or hemoglobin A(1c) criteria were met by 89.7% of prediabetic patients. A statistically significant intergroup gradient from normal glucose tolerance to prediabetes and from prediabetes to diabetes mellitus was observed for waist circumference, triglycerides, fasting insulin levels, and frequency of metabolic syndrome (P = .02 to P prediabetic patients (6.6%) met the 2010 ADA criteria for treatment with metformin. Prediabetes is highly prevalent in adults treated with antipsychotic drugs and correlates with markers of increased intraabdominal adiposity, enhanced lipolysis, and insulin resistance. Criteria for using metformin to prevent the emergence of diabetes mellitus may need to be

    The dynamic modulus G(*) of a viscoelastic medium is often measured by following the trajectory of a small bead subject to Brownian motion in a method called "passive microbead rheology." This equivalence between the positional autocorrelation function of the tracer bead and G(*) is assumed via the generalized Stokes-Einstein relation (GSER). However, inertia of both bead and medium are neglected in the GSER so that the analysis based on the GSER is not valid at high frequency where inertia is important. In this paper we show how to treat both contributions to inertia properly in one-bead passive microrheological analysis. A Maxwell fluid is studied as the simplest example of a viscoelastic fluid to resolve some apparent paradoxes of eliminating inertia. In the original GSER, the mean-square displacement (MSD) of the tracer bead does not satisfy the correct initial condition. If bead inertia is considered, the proper initial condition is realized, thereby indicating an importance of including inertia, but the MSD oscillates at a time regime smaller than the relaxation time of the fluid. This behavior is rather different from the original result of the GSER and what is observed. What is more, the discrepancy from the GSER result becomes worse with decreasing bead mass, and there is an anomalous gap between the MSD derived by naïvely taking the zero-mass limit in the equation of motion and the MSD for finite bead mass as indicated by McKinley et al. [J. Rheol. 53, 1487 (2009)]. In this paper we show what is necessary to take the zero-mass limit of the bead safely and correctly without causing either the inertial oscillation or the anomalous gap, while obtaining the proper initial condition. The presence of a very small purely viscous element can be used to eliminate bead inertia safely once included in the GSER. We also show that if the medium contains relaxation times outside the window where the single-mode Maxwell behavior is observed, the oscillation can be

    Artemisinin derivatives may have advantages over quinoline drugs for treating severe malaria since they are fast acting and effective against quinine resistant malaria parasites. The objective of this review was to assess the effects of artemisinin drugs for severe and complicated falciparum malaria in adults and children. We searched the Cochrane Infectious Diseases Group trials register, Cochrane Controlled Trials Register, Medline, Embase, Science Citation Index, Lilacs, African Index Medicus, conference abstracts and reference lists of articles. We contacted organisations, researchers in the field and drug companies. Randomised and pseudo-randomised trials comparing artemisinin drugs (rectal, intramuscular or intravenous) with standard treatment, or comparisons between artemisinin derivatives in adults or children with severe or complicated falciparum malaria. Eligibility, trial quality assessment and data extraction were done independently by two reviewers. Study authors were contacted for additional information. Twenty three trials are included, allocation concealment was adequate in nine. Sixteen trials compared artemisinin drugs with quinine in 2653 patients. Artemisinin drugs were associated with better survival (mortality odds ratio 0.61, 95% confidence interval 0.46 to 0.82, random effects model). In trials where concealment of allocation was adequate (2261 patients), this was barely statistically significant (odds ratio 0.72, 95% CI 0.54 to 0.96, random effects model). In 1939 patients with cerebral malaria, mortality was also lower with artemisinin drugs overall (odds ratio 0.63, 95% CI 0.44 to 0.88, random effects model). The difference was not significant however when only trials reporting adequate concealment of allocation were analysed (odds ratio 0.78, 95% CI 0.55 to 1.10, random effects model) based on 1607 patients. No difference in neurological sequelae was shown. Compared with quinine, artemisinin drugs showed faster parasite clearance from

    Postpartum haemorrhage (PPH) - heaving bleeding within the first 24 hours after giving birth - is one of the main causes of death of women after childbirth. Antifibrinolytics, primarily tranexamic acid (TXA), have been shown to reduce bleeding in surgery and safely reduces mortality in trauma patients with bleeding without increasing the risk of adverse events.An earlier Cochrane review on treatments for primary PPH covered all the various available treatments - that review has now been split by types of treatment. This new review concentrates only on the use of antifibrinolytic drugs for treating primary PPH. To determine the effectiveness and safety of antifibrinolytic drugs for treating primary PPH. We searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) (28 May 2017) and reference lists of retrieved studies. Randomised controlled trials (RCTs), including cluster-randomised trials of antifibrinolytic drugs (aprotinin, TXA, epsilon-aminocaproic acid (EACA) and aminomethylbenzoic acid, administered by whatever route) for primary PPH in women.Participants in the trials were women after birth following a pregnancy of at least 24 weeks' gestation with a diagnosis of PPH, regardless of mode of birth (vaginal or caesarean section) or other aspects of third stage management.We have not included quasi-randomised trials, or cross-over studies. Studies reported as abstracts have not been included if there was insufficient information to allow assessment of risk of bias.In this review we only identified studies looking at TXA. Two review authors independently extracted data from each study using an agreed form. We entered data into Review Manager software and checked for accuracy.For key review outcomes, we rated the quality of the evidence as 'high', 'moderate', 'low' or 'very low' according to the GRADE approach. Three trials (20,412 women) met our inclusion criteria. Two trials

    Pressure ulcers are common in clinical practice and pose a significant health problem worldwide. Apart from causing suffering to patients, they also result in longer hospital stays and increase the cost of health care. A variety of methods are used for treating pressure ulcers, including pressure relief, patient repositioning, biophysical strategies, nutritional supplementation, debridement, topical negative pressure, and local treatments including dressings, ointments and creams such as bacitracin, silver sulphadiazine, neomycin, and phenytoin. Phenytoin is a drug more commonly used in the treatment of epilepsy, but may play an important role in accelerating ulcer healing. To assess the effects of topical phenytoin on the rate of healing of pressure ulcers of any grade, in any care setting. In September 2016, we searched the following electronic databases to identify relevant randomized clinical trials: the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL; the Cochrane Library); Ovid MEDLINE; Ovid Embase; and EBSCO CINAHL Plus. We handsearched conference proceedings from the European Pressure Ulcer Advisory Panel, European Wound Management Association and the Tissue Viability Society for all available years. We searched the references of the retrieved trials to identify further relevant trials. We also searched clinical trials registries to identify ongoing and unpublished studies. There were no restrictions with respect to language, date of publication or study setting. We included all randomized controlled trials (RCTs) addressing the effects (both benefits and harms) of topical phenytoin on the healing of pressure ulcers of any grade compared with placebo or alternative treatments or no therapy, irrespective of blinding, language, and publication status. Two review authors independently selected studies, extracted information on participants, interventions, methods and results and assessed risk of bias using

    The limited medication for major depressive disorder (MDD) against an ever-rising disease burden presents an urgent need for therapeutic innovations. During recent years, studies looking at the systems regulation of mental health and disease have shown a remarkably powerful control of MDD by systemic signals. Meanwhile, the identification of a host of targets outside the brain opens the way to treat MDD by targeting systemic signals. We examine these emerging findings and consider the implications for current thinking regarding MDD pathogenesis and treatment. We highlight the opportunities and challenges of a periphery-targeting strategy and propose its incorporation into a holistic approach. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available We describe an original protocol Treating Depression Downhill (TDD that was designed as a specific therapy for depression. Evolutionary theories of depression served as a basis for its development. We discuss the rationale for using evolutionary theory and describe the structure and integrative nature of TDD. We then present an observation on TDD’s application to group therapy of active duty military personnel. In the described sample, TDD demonstrated effectiveness and specificity for depression, differentiating it from anxiety and personality disorders.

    Poor voice quality due to functional dysphonia can lead to a reduced quality of life. In occupations where voice use is substantial it can lead to a loss of employment. To evaluate the effectiveness of interventions to treat functional dysphonia in adults. We searched MEDLINE (PubMed, 1950 to 2006), EMBASE (1974 to 2006), CENTRAL (The Cochrane Library, Issue 2 2006), CINAHL (1983 to 2006), PsychINFO (1967 to 2006), Science Citation Index (1986 to 2006) and the Occupational Health databases OSH-ROM (to 2006). The date of the last search was 5(th) April 2006. Randomised controlled trials (RCTs) of interventions evaluating the effectiveness of treatments targeted at adults with functional dysphonia. For work-directed interventions interrupted time series and prospective cohort studies were also eligible. Two authors independently extracted data and assessed trial quality. Meta-analysis was performed where appropriate. We identified six randomised controlled trials including a total of 163 participants in intervention groups and 141 controls. One trial was high quality. Interventions were grouped into 1) Direct voice therapy 2) Indirect voice therapy 3) Combination of direct and indirect voice therapy and 4) Other treatments: pharmacological treatment and vocal hygiene instructions given by phoniatrist. No studies were found evaluating direct voice therapy on its own. One study did not show indirect voice therapy on its own to be effective when compared to no intervention. There is evidence from three studies for the effectiveness of a combination of direct and indirect voice therapy on self-reported vocal functioning (SMD -1.07; 95% CI -1.94 to -0.19), on observer-rated vocal functioning (WMD -13.00; 95% CI -17.92 to -8.08) and on instrumental assessment of vocal functioning (WMD -1.20; 95% CI -2.37 to -0.03) when compared to no intervention. The results of one study also show that the remedial effect remains significant for at least 14 weeks on self-reported vocal

Specific patient categories A trial of 300 intravenous drug users in the USA evaluated direct observation with no observation in TB prophylaxis to prevent active disease and showed little difference in treatment completion (RR 1.00, 95% CI 0.88 to 1.13; one trial, 300 participants, low quality evidence). Authors' conclusions From the existing trials, DOT did not provide a solution to poor adherence in TB treatment. Given the large resource and cost implications of DOT, policy makers might want to reconsider strategies that depend on direct observation. Other options might take into account financial and logistical barriers to care; approaches that motivate patients and staff; and defaulter follow-up. PLAIN LANGUAGE SUMMARY Directly observing people with TB take their drugs to help them complete their treatment This Cochrane Review summarises trials evaluating the effects of directly observed therapy (DOT) for treating people with tuberculosis (TB) or people on prophylaxis to prevent active disease compared to self-administered treatment. After searching for relevant trials up to 13 January 2015, we included 11 randomized controlled trials, enrolling 5662 people with TB, and conducted between 1995 and 2008. What is DOT and how might it improve treatment outcomes for people with TB DOT is one strategy to ensure that patients with TB take all their medication. An 'observer' acceptable to the patient and the health system observes the patient taking every dose of their medication, and records this for the health system to monitor. The World Health Organization currently recommends that people with TB are treated for at least six months to achieve cure. These long durations of treatment can be difficult for patients to complete, especially once they are well and need to return to work. Failure to complete treatment can lead to relapse and even death in individuals, and also has important public health consequences, such as increased TB transmission and the

    Lung cancer in pregnancy is a rare situation; however, it is increasingly reported in the past two decades. The association might be more encountered in the coming years due to the rising trends of cigarette smoking among young women and tendency to delay pregnancy to later in life. We performed a literature search without any date or language restriction and identified 44 cases diagnosed and/or treated for lung cancer during the course of pregnancy. Patients had poor post-partum outcome with less than one-forth alive at 1 year following delivery. There was a high incidence of metastases to the products of conception reaching 26%. Eight patients were treated with systemic therapies during the course of gestation with normal fetal outcome and no evidence of fetal or placental metastases. Counseling of these patients is very important. Apart from the clinical conflict they pose, some ethical aspects should be taken in consideration. The poor maternal prognosis should be discussed and the patient's autonomy should be respected to decide whether she wants to keep the pregnancy or not.

    Inadvertent postoperative hypothermia (a drop in core body temperature to below 36°C) occurs as an effect of surgery when anaesthetic drugs and exposure of the skin for long periods of time during surgery result in interference with normal temperature regulation. Once hypothermia has occurred, it is important that patients are rewarmed promptly to minimise potential complications. Several different interventions are available for rewarming patients. To estimate the effectiveness of treating inadvertent perioperative hypothermia through postoperative interventions to decrease heat loss and apply passive and active warming systems in adult patients who have undergone surgery. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (2014, Issue 2), MEDLINE (Ovid SP) (1956 to 21 February 2014), EMBASE (Ovid SP) (1982 to 21 February 2014), the Institute for Scientific Information (ISI) Web of Science (1950 to 21 February 2014) and the Cumulative Index to Nursing and Allied Health Literature (CINAHL), EBSCO host (1980 to 21 February 2014), as well as reference lists of articles. We also searched www.controlled-trials.com and www.clincialtrials.gov. Randomized controlled trials of postoperative warming interventions aiming to reverse hypothermia compared with control or with each other. Three review authors identified studies for inclusion in this review. One review author extracted data and completed risk of bias assessments; two review authors checked the details. Meta-analysis was conducted when appropriate by using standard methodological procedures as expected by The Cochrane Collaboration. We included 11 trials with 699 participants. Ten trials provided data for analysis. Trials varied in the numbers and types of participants included and in the types of surgery performed. Most trials were at high or unclear risk of bias because of inappropriate or unclear randomization procedures, and because blinding of assessors and participants generally was

Para a avaliação antibacteriana in vitro, foram utilizados cinco patógenos bacterianos incluindo espécies gram-positivas e espécies gram-negativas mediante o uso do método de difusão em ágar. Para a avaliação da atividade cicatrizante, foram utilizados 40 ratos da linhagem Wistar, divididos em dois grupos: o grupo I, composto por 20 ratos com feridas cutâneas, tratados com aplicação tópica do creme base com 10% de óleo de buriti, e o grupo II, controle, com o mesmo número de animais que receberam a aplicação tópica do creme base. A aplicação do produto foi realizada em feridas padronizadas, circulares de 1cm de diâmetro na região dorsolombar. As avaliações clínica, morfométrica e histopatológica das feridas foram realizadas no 3°, 7°, 14° e 21° dias. Em relação à avaliação da atividade antibacteriana, os resultados mostraram que houve inibição do crescimento bacteriano em quatro dos cinco patógenos testados. Em relação à área da ferida, foi observada redução significativa da área no 14o dia e maior percentual de contração das feridas do grupo tratado em relação ao controle. No décimo quarto dia, as feridas tratadas com o óleo do buriti apresentavam aumento significativo na contagem de fibroblastos e fibras colágenas, além de completo processo de reepitelização, enquanto o grupo controle necessitava de mais tempo para resolução do processo cicatricial.The aim of this study was to evaluate the in vitro antimicrobial activity and wound healing effect of buriti oil (M. flexuosa in rats.

    The aims of this study are to describe non-healing in the treated vertebral body after percutaneous vertebroplasty and analyze the influence of vacuum cleft, location, and severity of collapse on the development of nonunion cement. Of 208 patients (266 treated vertebral bodies) who were treated with percutaneous vertebroplasty from September 2002 to May 2006, 23 patients (41 treated levels) with residual or recurrent pain underwent follow-up magnetic resonance imaging (MRI) study. Retrospective chart review with analysis of preoperative and postoperative MRIs were performed in these 23 patients. In the 41 treated vertebral bodies, 22 of 41 bodies had vacuum cleft found in the preoperative MRI study. Eight of the 22 treated vertebral bodies with preoperative vacuum clefts were found to have fluid between the interface of cement and the residual bone in the collapsed vertebral bodies on follow-up MRI. The adjacent discs of these treated vertebral bodies were upward/downward displaced. The endplate of the adjacent vertebral body exhibited fibrotic change. Treated bodies with vacuum clefts and level A location (T9, T11, T12, and L1) had higher probability of developing nonunion of the cement with statistical significance. The probability of nonunion cement in severe collapsed bodies might be higher than that of union cement in mild collapsed ones, but was not statistically significant. Fluid sign in the treated body represents unhealed bone-cement interface. The location of the treated vertebral body and existence of vacuum cleft in the treated bodies may be important factors influencing the nonunion of cement. (orig.)

  15. Biologically Pre-Treated Habitation Waste Water as a Sustainable Green Urine Pre-Treat Solution

    The ability to recover water from urine and flush water is a critical process to allow long term sustainable human habitation in space or bases on the moon or mars. Organic N present as urea or similar compounds can hydrolyze producing free ammonia. This reaction results in an increase in the pH converting ammonium to ammonia which is volatile and not removed by distillation. The increase in pH will also cause precipitation reactions to occur. In order to prevent this, urine on ISS is combined with a pretreat solution. While use of a pretreatment solution has been successful, there are numerous draw backs including: storage and use of highly hazardous solutions, limitations on water recovery (less than 85%), and production of brine with pore dewatering characteristics. We evaluated the use of biologically treated habitation wastewaters (ISS and early planetary base) to replace the current pretreat solution. We evaluated both amended and un-amended bioreactor effluent. For the amended effluent, we evaluated "green" pretreat chemicals including citric acid and citric acid amended with benzoic acid. We used a mock urine/air separator modeled after the urine collection assembly on ISS. The urine/air separator was challenged continually for >6 months. Depending on the test point, the separator was challenged daily with donated urine and flushed with amended or un-amended reactor effluent. We monitored the pH of the urine, flush solution and residual pH in the urine/air separator after each urine event. We also evaluated solids production and biological growth. Our results support the use of both un-amended and amended bioreactor effluent to maintain the operability of the urine /air separator. The ability to use bioreactor effluent could decrease consumable cost, reduce hazards associated with current pre-treat chemicals, allow other membrane based desalination processes to be utilized, and improve brine characteristics.

    The role the human immunodeficiency virus (HIV) and antiretroviral treatment on endothelial activation, and the subsequent relationship with cardiovascular disease, is not well understood. We investigated endothelial activation, inflammatory and cardiometabolic profiles, and measures of vascular structure and function of 66 antiretroviral treated (ART), 78 never-treated (no-ART) HIV infected and 165 HIV free Africans. Blood samples were obtained for biochemical analysis and blood pressure, pulse wave velocity (PWV) and carotid intima-media thickness (IMT) measurements were performed. The HIV infection duration was at least five years and the treatment 2.86±0.13 years. The intracellular adhesion molecule (ICAM) and vascular cell adhesion molecule (VCAM) levels were elevated in the HIV infected groups compared to the controls. The odds of higher adhesion molecule levels were increased when HIV infected (especially in the no-ART group); OR no-ART vs. no-HIV: ICAM 3.92 (2.2-7.0); VCAM 16.2 (7.5-35). ICAM and VCAM associated with HIV status and interleukin-6 (IL-6) in the total group (all pART: β=-0.28, p=0.01; ART: β=-0.22, p=0.07) and TC (no-ART: β=-0.36, pART: β=-0.27, p=0.03). The ART group had an unfavourable lipid profile compared to the no-ART group. The inflammatory markers (C-reactive protein (CRP) and IL-6), PWV and IMT did not differ between the three groups. HIV infected Africans showed endothelial activation when compared to HIV free controls. The endothelial activation was not accompanied by increased inflammation (as measured with CRP and IL-6), arterial stiffness or sub-clinical atherosclerosis. Copyright © 2015 Elsevier Ireland Ltd.

    1980-01-01

    Six hundred and thirteen consecutive patients with Hodgkin's disease (HD), with a follow-up of two to ten years, were reviewed with the aim of establishing the type and frequency of second malignancies. Acute non-lymphoid leukemia developed in 2 of 152 patients treated by chemotherapy (CHT), and in 5 of 344 patients treated by CHT and radiotherapy (RT). Leukemia developed 12 to 83 months after diagnosis of HD, was always preceded by a preleukemic phase (3 to 25 months), and was always fatal (after 1 to 12 months). The karyotype of leukemic cells was studied in 4 of 7 patients and was always abnormal. Solid tumors developed in 1 of 152 patients treated by CHT, and in 4 of 344 patients treated by CHT and RT. The tumors appeared 10 to 63 months after diagnosis of HD and killed all 5 patients after 10 to 16 months. For patients treated by CHT, the actuarial frequency of leukemia and other tumors seven years after diagnosis of HD was 2.0% and 1.26%, respectively. For patients treated by CHT and RT, the figures were 2.04% and 2.26%, respectively. Second malignancies were not recorded among 117 patients treated by RT alone. These data are consistent with a relationship of acute leukemia to therapy for HD

    Conventional wet treatment, desizing, scouring and bleaching, for grey cotton fabric involves the use of high water, chemical and energy consumption which may not be considered as a clean process. This study aims to investigate the efficiency of the atmospheric pressure plasma (APP) treatment on treating grey cotton fabric when compared with the conventional wet treatment. Grey cotton fabrics were treated with different combinations of plasma parameters with helium and oxygen gases and also through conventional desizing, scouring and bleaching processes in order to obtain comparable results. The results obtained from wicking and water drop tests showed that wettability of grey cotton fabrics was greatly improved after plasma treatment and yielded better results than conventional desizing and scouring. The weight reduction of plasma treated grey cotton fabrics revealed that plasma treatment can help remove sizing materials and impurities. Chemical and morphological changes in plasma treated samples were analysed by FTIR and SEM, respectively. Finally, dyeability of the plasma treated and conventional wet treated grey cotton fabrics was compared and the results showed that similar dyeing results were obtained. This can prove that plasma treatment would be another choice for treating grey cotton fabrics. Copyright © 2013 Elsevier Ltd. All rights reserved.

    2017-02-08

    To examine the extent to which the theory of planned behavior (TPB) predicts academic clinicians' intent to treat pediatric obesity. A multi-disciplinary panel iteratively devised a Likert scale survey based on the constructs of the TPB applied to a set of pediatric obesity themes. A cross-sectional electronic survey was then administered to academic clinicians at tertiary care centers across Canada from January to April 2012. Descriptive statistics were used to summarize demographic and item agreement data. A hierarchical linear regression analysis controlling for demographic variables was conducted to examine the extent to which the TPB subscales predicted intent to treat pediatric obesity. A total of 198 physicians, surgeons, and allied health professionals across Canada (British Columbia, Alberta, Manitoba, Saskatchewan, Nova Scotia, Ontario and Quebec) completed the survey. On step 1, demographic factors accounted for 7.4% of the variance in intent scores. Together in step 2, demographic variables and TPB subscales predicted 56.9% of the variance in a measure of the intent to treat pediatric obesity. Perceived behavioral control, that is, confidence in one's ability to manage pediatric obesity, and subjective norms, congruent with one's context of practice, were the most significant predictors of the intent to treat pediatric obesity. Attitudes and barriers did not predict the intent to treat pediatric obesity in this context. Enhancing self-confidence in the ability to treat pediatric obesity and the existence of supportive treatment environments are important to increase clinician's intent to treat pediatric obesity.

    Dr C. Autious has just returned from the most prestigious vascular surgery meeting in America. At the meeting, one of the most prominent complex aneurysm surgeons arose to discuss a paper concerning a procedure he had developed and popularized over the last decade. Dr L. Uminous stunned the audience with his declaration that he no longer recommends that his namesake procedure be performed. Instead, he proclaimed that a new, radically different procedure be adopted immediately. He showed slides detailing the novel proposal but did not give data concerning results obtained. The recommended procedure is technically possible but seems to require a different skill set. Dr Autious has a patient scheduled for elective surgery that he had planned to use the Uminous procedure to treat. What should he do? A. Do the recommended procedure as best you can. B. Refer the patient to Dr Uminous. C. Offer the recommended procedure with full disclosure. D. Give full disclosure and let the patient decide which procedure to use. E. Put the procedure on hold until more information becomes available. Copyright © 2015 Society for Vascular Surgery. Published by Elsevier Inc. All rights reserved.

    Full Text Available Clinical success of endodontically treated posterior teeth is determined by the postendodontic restoration. Several options have been proposed to restore endodontically treated teeth. Endocrowns represent a conservative and esthetic restorative alternative to full coverage crowns. The preparation consists of a circular equigingival butt-joint margin and central retention cavity into the entire pulp chamber constructing both the crown and the core as a single unit. The case reports discussed here are moderately damaged endodontically treated molars restored using all ceramic endocrowns fabricated using two different systems, namely, CAD/CAM and pressed ceramic.

    1968-04-09

    A method of well stimulation consists of introducing a fluid medium into the well separate from the treating fluid. A volume is created within the medium of pressure less than that of the medium adjacent to the formation to be treated. This is performed by substantially instantaneously collapsing the created volume, which creates at least one rarefactional wave pulse. This is followed by a compressional wave pulse. The treating fluid is injected into the fluid medium in time sequence with the compressional wave pulse. The rarefactional and compressional pulses are conducted to the formation. (14 claims)

    2018-03-01

    This research examined the phytoestrogen potential of Calliandra calothyrsus leaf extract in prepubertal female rat (Rattus norvegicus). Sixty weaned female rats (21 days old) were divided into five groups i.e. control (K), negative control which was given 0.5% Na CMC suspension (KN) and treatment groups which were given with C. calothyrsus ethanolic leaf extract doses 25 mg/kg bw (P1), 50 mg/kg bw (P2) and 75 mg/kg bw (P3). The treatment suspension was administered 0.5 mL/rat/day by gavage for 28 days, started at the age of 21st days old. The rats were sacrificed and the blood samples were collected from 4 rats / group at the age of 28th, 42nd and 56th days old, each. The concentration of estrogen hormone levels were measured from blood serum by ELISA kit and were read at 450 nm wavelength with an ELISA Spectrophotometer. Data was analyzed statistically by General Linear Model with 95% of confidence. The result showed that rat’s body weight decreased significantly with the higher doses and the longer the treatment of C. calothyrsus leaf extract due to the anti-nutritive activity of calliandra tannins. The estrogen hormone level was significantly increased at the highest dose. The highest estrogen levels were found in the group of female rats which were given the exctract of 75 mg/kg bw until the age of 42nd days. This results showed that there was a phytoestrogen potential in the C. calothyrsus leaf extract.

    In order to resolve some key LMFBR safety issues, ANL personnel are modifying the TREAT reactor to handle much larger experiments. As a result of these modifications, the upgraded Treat reactor will not always operate in a self-limited mode. During certain experiments in the upgraded TREAT reactor, it is possible that the fuel could be damaged by overheating if, once the computer systems fail, the reactor scram system (RSS) fails on demand. To help ensure that the upgraded TREAT reactor is shut down when required, ANL personnel have designed a triply redundant RSS for the facility. The RSS is designed to meet three reliability goals: (1) a loss of capability failure probability of 10 -9 /demand (independent failures only); (2) an inadvertent shutdown probability of 10 -3 /experiment; and (3) protection agaist any known potential common cause failures. According to ANL's reliability analysis of the RSS, this system substantially meets these goals

    Esophageal stent fractures occur quite rarely. A 61-year-old male patient was previously treated for rupture of benign stenosis, occurring after dilatation, by implanting an esophageal stent. However, a year after implantation, the patient suffered from dysphagia caused by the broken esophageal stent. He was treated with the interventional radiology technique, whereby a second implantation of the esophageal stent was carried out quite successfully.
