Ashok Kumar,V.M.S. Sriwastwa,S. Lata,R.K. Tiwari
Pakistan Journal of Biological Sciences , 2012,
Abstract: It is known that humidity enhances the growth of mites in carpets, mattresses and other household items. The association between exposure to house dust and diseases such as asthma, chronic rhinitis and atopic dermatitis has been shown in many individuals. Large quantities of carpet dyes are used in carpet industry located in Eastern Uttar Pradesh India. Nearly 90% of the carpets are manufactured in Eastern Uttar Pradesh and remaining 10% is produced in Kashmir and other places of India. Therefore, this area is important in huge dyeing and washing industry in which nearly 760 metric tons of dyes and dye supporting chemicals as well as washing chemicals are used per year. Present study has been conducted to see the adverse health effects of carpet dye black T supra which is being greatly used in carpet industry. In the present study, Gram mixed with 20 mg kg-1 of b.wt. day-1 sub-lethal dose of Black T Supra carpet dye was fed to Rattus norvegicus for three months and the symptoms of dermatitis in the form of hair fall in patches on surface of body started from fifth week onward. The area of patches of hair fall increased between 6-12th weeks. In controls, such effect was not observed. In addition, a little increase in body weight, cataract in eyes and desperate walking in experimental animals were observed after fifth week of feeding Black T Supra dye. In some cases, the correlation between exposure to carpet dye black T supra and symptoms is obvious.

Abstract: it is an article of integrative literature review on trends or patterns of evaluation in nursing undergraduate courses that highlights and discusses the different methodologies adopted in latin america. as methodological framework, the six steps of ganong methodology were adopted, indicated for a integrative literature review. a national, international and active literature review search was conducted in scielo, lilacs, medline, abed, bdenf homeoindex, paho. the descriptors selected for the literature search were education, nursing education, educational evaluation, educational technology and nursing. eighty articles published from 2004 to 2008 were found, 30 of then were excluded, including duplicate productions, letters, editorials, abstracts and products unrelated to the scope of the study, remaining 50 articles for analysis. data evaluation indicated different educational concepts adopted in teaching and learning evaluation. there are, for example the ones guided by the concepts of banking education that alienate, imprison and reproduce the distorted and erroneous ideological positions of that trend. in critical school design there is a predominance of open, critical and reflective evaluation methods consistent with the progressive, constructivist and sociointeractionist theoretical framework guided by the brazilian national curriculum guidelines (pcn), which impels the curriculum to a search for completeness and for the notion of dialogic competence raised from the combination of attributes (cognitive, attitude and skills) that guide the teaching processes.

Revista da Associa??o Médica Brasileira , 2001,
Abstract: A desnutri o está freqüentemente relacionada com doen as cr nicas. O diagnóstico precoce realizado por técnicas práticas e simples favorece o tratamento, minimizando as complica es. OBJETIVO: avaliar a situa o nutricional de crian as e adolescentes com insuficiência renal cr nica (IRC) utilizando parametros antropométricos. MéTODOS: Foram avaliadas 41 crian as e adolescentes com IRC ("clearance" de creatinina abaixo de 50 ml/min/1,73m2) acompanhadas no Ambulatório de Nefrologia Pediátrica do HC-Unicamp, de janeiro de 1995 a novembro de 1996, pelas medidas do perímetro braquial (PB) e da prega cutanea tricipital (PCT), com as quais calculou-se a área de gordura braquial (AGB) e área muscular braquial (AMB) e os respectivos escores z. Estas medidas foram realizadas pelo menos duas vezes, com intervalo de 0,21 a 1,3 anos (0,88 ± 0,04). RESULTADOS: Os escores z obtidos tanto para PB, como para PCT, AGB e AMB apresentaram valores muito baixos, sendo que, na evolu o, apenas o escore z de AMB apresentou melhora estatisticamente significativa (p= 0,03 teste de Wilcoxon). Quando selecionados quanto ao tratamento de substitui o renal, apenas os transplantados renais apresentaram melhora estatisticamente significativa para o escore z de PB (p= 0,02 teste de Wilcoxon). CONCLUS O: Estes dados mostram uma situa o nutricional comprometida tanto em rela o à reserva de gordura, quanto de músculo, com melhora no acompanhamento apenas em rela o à área muscular.

Abstract: we have tested the hypothesis that restless leg syndrome (rls) is related to quality of sleep, fatigue and clinical disability in multiple sclerosis (ms). the diagnosis of rls used the four minimum criteria defined by the international restless legs syndrome study group. fatigue was assessed by the fatigue severity scale (fss >27), quality of sleep by the pittsburgh sleep quality index (psqi >6), excessive daytime sleepiness by the epworth sleepiness scale (ess >10) and clinical disability by the expanded disability status scale (edss). forty-four patients (32 women) aged 14 to 64 years (43 ± 14) with disease from 0.4 to 23 years (6.7 ± 5.9) were evaluated. thirty-five were classified as relapsing-remitting, 5 as primary progressive and 4 as secondary progressive. edss varied from 0 to 8.0 (3.6 ± 2.0). rls was detected in 12 cases (27%). patients with rls presented greater disability (p = 0.01), poorer sleep (p = 0.02) and greater levels of fatigue (p = 0.03). impaired sleep was present in 23 (52%) and excessive daytime sleepiness in 3 cases (6.8%). fatigue was present in 32 subjects (73%) and was associated with clinical disability (p = 0.000) and sleep quality (p = 0.002). age, gender, disease duration, ms pattern, excessive daytime sleepiness and the presence of upper motor neuron signs were not associated with the presence of rls. fatigue was best explained by clinical disability and poor sleep quality. awareness of rls among health care professionals may contribute to improvement in ms management.

Abstract: disturbed sleep is common in chronic obstructive pulmonary disease (copd). conventional hypnotics worsen nocturnal hypoxemia and, in severe cases, can lead to respiratory failure. exogenous melatonin has somnogenic properties in normal subjects and can improve sleep in several clinical conditions. this randomized, double-blind, placebo-controlled study was carried out to determine the effects of melatonin on sleep in copd. thirty consecutive patients with moderate to very severe copd were initially recruited for the study. none of the participants had a history of disease exacerbation 4 weeks prior to the study, obstructive sleep apnea, mental disorders, current use of oral steroids, methylxanthines or hypnotic-sedative medication, nocturnal oxygen therapy, and shift work. patients received 3 mg melatonin (n = 12) or placebo (n = 13), orally in a single dose, 1 h before bedtime for 21 consecutive days. sleep quality was assessed by the pittsburgh sleep quality index (psqi) and daytime sleepiness was measured by the epworth sleepiness scale. pulmonary function and functional exercise level were assessed by spirometry and the 6-min walk test, respectively. twenty-five patients completed the study protocol and were included in the final analysis. melatonin treatment significantly improved global psqi scores (p = 0.012), particularly sleep latency (p = 0.008) and sleep duration (p = 0.046). no differences in daytime sleepiness, lung function and functional exercise level were observed. we conclude that melatonin can improve sleep in copd. further long-term studies involving larger number of patients are needed before melatonin can be safely recommended for the management of sleep disturbances in these patients.

Abstract: Statistics based optimization methodology such as Box-Behnken Design was employed to study the effect and interaction among three influencing variables such as dye concentration (mg/L), pH and incubation time (hours) towards Acid Orange 10 dye uptake by casuarina charcoal. The range of variables in the study was determined from preliminary studies using One Factor At a Time (OFAT) approach. A17 trial Box-Behnken design generated using Design Expert 8.0 and optimized conditions were predicted. The optimal operating condition found to be; dye concentration of 30 mg/L, pH 7 and six hours of incubation at room temperature at static conditions yielded an experimental sorption uptake of 70.24mg/g. The predicted sorption uptake 71.59mg/g was in agreement with the experimental sorption with a error of 1.89%. We conclude that, the sorption uptake using locally available casuarina charcoal can be employed as a cheap alternative in removal of azo dyes using response surface methodology
