2. Study of pandrug and heavy metal resistance among E. coli from anthropogenically influenced Delhi stretch of river Yamuna
Abstract Escalating burden of antibiotic resistance that has reached new heights present a grave concern to mankind. As the problem is no longer confined to clinics, we hereby report identification of a pandrug resistant Escherichia coli isolate from heavily polluted Delhi stretch of river Yamuna, India. E. coli MRC11 was found sensitive only to tobramycin a

3. Analysis for the presence of determinants involved in the transport of mercury across bacterial membrane from polluted water bodies of India
Abstract Mercury, which is ubiquitous and recalcitrant to biodegradation processes, threatens human health by escaping to the environment via various natural and anthropogenic activities. Non-biodegradability of mercury pollutants has necessitated the development and implementation of economic alternatives with promising potential to remove metals from the e

4. Vitamin E and Sodium Selenite Against Mercuric Chloride-Induced Lung Toxicity in the Rats
The aim of the present study was to elucidate the possible protective role of vitamin E and / or sodium selenite on mercuric chloride-induced oxidative stress and histopathological changes in the lung tissue of the rats. Adult male albino Wistar rats were exposed to mercuric chloride (1.0 mg/kg day) for four weeks. Treatment with mercuric chloride led to oxi

5. Protective Effects of Sodium Selenite and Vitamin E on Mercuric Chloride-Induced Cardiotoxicity in Male Rats
This study was designed to investigate the protective effects of sodium selenite and/or vitamin E against mercuric chloride-induced cardiotoxicity. Male Wistar rats (n=48, 310±10 g) were administered mercuric chloride (1.0 mg/kg bw), sodium selenite (0.25 mg/kg bw), vitamin E (100 mg/kg bw), sodium selenite plus mercuric chloride, vitamin E plus mercuric ch

6. Comparison of two methods for in vitro multiplication of Radopholus similis and Pratylenchus brachyurus in carrot cylinders
The use of in vitro mass multiplication of nematodes under axenic conditions allows intensification of studies on taxonomy, biology, epidemiology and control of these pathogens. In the present study, two methods were compared for in vitro multiplication of two species of plant-parasitic nematodes, Radopholus similis and Pratylenchus brachyurus in 20, 40 and

7. EFEITOS DO CLORETO DE MERCÚRIO E DO CLORETO DE ZINCO SOBRE PARÂMETROS RENAIS E HEPÁTICOS EM RATAS LACTANTES E NÃO-LACTANTES / EFFECTS OF MERCURY CHLORIDE AND ZINC CHLORIDE ON RENAL AND HEPATIC PARAMETERS IN LACTATING AND NON-LACTATING RATS
O objetivo deste estudo foi comparar os efeitos da exposição ao cloreto de mercúrio (HgCl2) sobre parâmetros renais e hepáticos em ratas adultas não-lactantes e ratas lactantes e seus filhotes, e avaliar o possível efeito preventivo do zinco (Zn), administrado na forma de cloreto de zinco (ZnCl2), sobre os efeitos nefro e hepatotóxicos causados pela

8. Mycoremediation of Congo red dye by filamentous fungi
Azo, anthroquinone and triphenylmethane dyes are the major classes of synthetic colourants, which are difficult to degrade and have received considerable attention. Congo red, a diazo dye, is considered as a xenobiotic compound, and is recalcitrant to biodegradative processes. Nevertheless, during the last few years it has been demonstrated that several fung

9. Peripheral markers of oxidative stress in chronic mercuric chloride intoxication
The present study was designed to evaluate the time course changes in peripheral markers of oxidative stress in a chronic HgCl2 intoxication model. Twenty male adult Wistar rats were treated subcutaneously daily for 30 days and divided into two groups of 10 animals each: Hg, which received HgCl2 (0.16 mg kg-1 day-1), and control, receiving the same volume of

10. Evaluation techniques coupled to mass spectrometry (ICP-MS) aimed at the fractionation and chemical speciation of mercury in blood and plasma / Avaliação de técnicas acopladas à espectrometria de massas com plasma (ICP-MS) visando o fracionamento e a especiação química de mercúrio em sangue e plasma
Mercury (Hg) is one of the most toxic environmental pollutants. It exists primarily in three forms: elemental mercury (Hg0), or metallic mercury, inorganic mercury (Hg-i), particularly mercuric chloride and organic mercury (Hg-o), mainly represented by methylmercury (MeHg) and ethylmercury (EtHg), and the organic forms of mercury are more toxic than the inor

11. MERCURY EFFECTS ON ENZYMES ALANINE AMINOTRANSFERASE, LACTATE DEHYDROGENASE AND GLUCOSE 6-PHOSPHATASE ACTIVITIES FROM YOUNG RATS / EFEITOS DO MERCÚRIO SOBRE A ATIVIDADE DAS ENZIMAS ALANINA AMINOTRANSFERASE, LACTATO DESIDROGENASE E GLICOSE 6-FOSFATASE DE RATOS JOVENS
O mercúrio é um elemento tóxico, podendo acumular-se em organismos vivos causando-lhes vários danos. Estudos têm demonstrado que esse metal é capaz de causar várias alterações fisiológicas e bioquímicas em ratos jovens, as quais são prevenidas pela pré-exposição ao zinco. Assim, este trabalho investigou os efeitos in vivo e in vitro do HgCl2 e

12. IN VITRO GERMINATION, ESTABLISHMENT, REGENERATION AND CALLI INDUCTION IN EXPLANTS OF AÇOITA-CAVALO (Luehea divaricata Mart. &Zucc.) / GERMINAÇÃO, ESTABELECIMENTO, REGENERAÇÃO E CALOGÊNESE IN VITRO EM EXPLANTES DE AÇOITA-CAVALO (Luehea divaricata Mart. &Zucc.)
O avanço da biotecnologia na área florestal tem favorecido as técnicas de propagação in vitro de espécies que apresentam dificuldades na reprodução via sementes. Luehea divaricata Mart. &Zucc (açoita-cavalo), integrante da família Malvaceae, é uma espécie florestal que sofreu, nas últimas décadas, grande redução das áreas ocupadas por popula
