25. Effect of exposure to sublethal concentrations of sodium cyanide on the carbohydrate metabolism of the Indian Major Carp Labeo rohita (Hamilton, 1822)
Experiments were designed to study in-vivo effects of sodium cyanide on biochemical endpoints in the freshwater fish Labeo rohita. Fish were exposed to two sublethal concentrations (0.106 and 0.064mg/L) for a period of 15 days. Levels of glycogen, pyruvate, lactate and the enzymatic activities of lactate dehydrogenase (LDH), succinate dehydrogenase (SDH), gl

26. Comparative effects of mature coconut water (Cocos nucifera) and glibenclamide on some biochemical parameters in alloxan induced diabetic rats
In the present study, comparative effects of mature coconut water (Cocos nucifera L., Arecaceae) and glibenclamide in alloxan induced diabetic rats were evaluated. Diabetes mellitus was induced in Sprague-Dawly rats using alloxan monohydrate (150 mg kg-1 body weight). Treatment with lyophilized form of mature coconut water and glibenclamide in diabetic rats

27. The effect of intermittent cryotherapy on the activities of citrate synthase and lactate dehydrogenase in regenerating skeletal muscle
This study examined the effect of three sessions of cryotherapy (three sessions of 30 minutes applied each 2 h) and muscle compression in the regenerating skeletal muscle of the rats. The middle belly of tibialis anterior muscle was injured by a frozen iron bar and received one of the following intervention: injury + cryotherapy (treated with cryotherapy); i

28. Phytomonas serpens: caracterização da piruvato/indolpiruvato descarboxilase e funcionalidade da auxina produzida. / Phytomonas serpens: characterization of the pyruvate/indolepyruvate decarboxylase and functionality of the auxin produced.
Um gene que codifica uma piruvato/indolpiruvato descarboxilase (PDC/IPDC) está presente no tripanossomatídeo de plantas Phytomonas serpens. A PDC atua na fermentação alcoólica, enquanto que a IPDC atua na biossíntese do fitormônio ácido indol-3-acético (AIA). Análises filogenéticas indicam que a PDC/IPDC de P. serpens é monofilética com IPDCs de

29. Hepatoprotective efficacy of Hypnea muciformis ethanolic extract on CCl4 induced toxicity in rats
The ethanolic extract of Hypnea muciformis (red algae) was tested for hepatoprotective activity against experimentally induced liver damage by Carbon tetrachloride (CCl4) in male albino rats. The levels of serum enzymatic and biochemical parameters such as serum glutamate oxaloacetate transaminase (SGOT), Serum glutamate pyruvate transaminase (SGPT), alkalin

30. Antidiabetic activity of Pseudarthria viscida aqueous root extract in neonatal streptozotocin-induced NIDDM rats
The antidiabetic activity of the aqueous root extract of Pseudarthria viscida (L.) Wight & Arn., Fabaceae, was investigated in normal and neonatal streptozotocin (n2-STZ)-induced non insulin-dependent diabetes mellitus (NIDDM) rats and compared with glibenclamide as a reference standard. Two different doses (250 and 500 mg/kg) of the extract were administere

31. Metabolic networks and bioenergetics of Aurantiochytrium sp. B-072 during storage lipid formation
Baffled shake flask cultivation of Aurantiochytrium sp. B-072 was carried out at in a glucose-monosodium glutamate mineral medium at different C/N-ratios (30-165) with glucose fixed at 90 g/L. With increasing C/N-ratio, a modest increase in lipid content (60 to 73 % w/w) was observed whereas fat-free biomass decreased but overall biomass showed little variat

32. Caracterização química dos géis produzidos pelas bactérias diazotróficas Rhizobium tropici e Mesorhizobium sp.
The exopolysaccharides with characteristics of gel produced by Rhizobium tropici (EPS RT) and Mesorhizobium sp (EPS MR) are acidic heteropolysaccharide composed mainly of glucose and galactose in a molar ratio of 4:1 and 5:1 respectively, with traces of mannose (~ 1%). Chemical analysis showed the presence of uronic acid, pyruvate and acetyl-substituents in

33. UDP-N-acetilglicosamina enolpiruvil transferase: determinação dos estados de protonação de resíduos de aminoácidos do sítio ativo pelo método PM6
UDP-N-acetylglucosamine-enolpyruvyl transferase (MurA) catalyzes the reaction between phosphoenol pyruvate and UDP-N-acetylglucosamine. We present a theoretical approach using the semiempirical PM6 method for defining protonation state of three active site residues, K22, H125, and K160. Prior comparison with neutron diffraction data showed that PM6 accuratel

34. Efeitos do etil-piruvato no tratamento da resposta inflamatória da lesão pulmonar na pancreatite aguda necrosante induzida em ratos. / Effects of ethyl-pyruvate in the inflammatory response of lung injury in experimental acute pancreatitis in rats.
INTRODUCTION: Severe acute pancreatitis (AP) is characterized by hemodynamic alterations and systemic inflammatory response leading to a high mortality rate. In AP the inappropriate activation of pancreatic enzymes plays an important role in pancreas autodigestion and in the inflammatory mechanisms responsible for the systemic response of the disease.

35. Efeito da adição de antioxidantes na qualidade do sêmen criopreservado de bovino / Effect of antioxidants on quality of bovine semen cryopreserved
Os antioxidantes têm como função neutralizar os efeitos dos radicais livres proporcionando uma melhor qualidade do sêmen fresco e criopreservado. O objetivo deste trabalho foi estudar o efeito da adição dos antioxidantes catalase, α-tocoferol e piruvato de sódio no sêmen bovino visando um controle das espécies reativas de oxigênio para melhora
