Current studies, particularly in Arabidopsis, have demonstrated that mutants deficient cytosolic ascorbate peroxidases (APXs) are susceptible to the oxidative damage induced by abiotic stress. In contrast, we demonstrate here rice double silenced for APXs (APx1/2s) up-regulated other peroxidases, making able cope with stress, such as salt, heat, high light and methyl viologen, similar non-transformed (NT) plants. The APx1/2s exhibited an altered redox homeostasis, indicated increased levels...
The physiological role of plant mitochondrial glutathione peroxidases is scarcely known. This study attempted to elucidate the a rice isoform (GPX1) in photosynthesis under normal growth and salinity conditions. GPX1 knockdown lines (GPX1s) were tested absence presence 100 mM NaCl for 6 d. Growth reduction GPX1s line non-stressful conditions, compared with non-transformed (NT) plants occurred parallel increased H2 O2 decreased GSH contents. These changes concurrently impairment, particularly...
Estudou-se o efeito da aplicação exógena de peróxido hidrogênio (H2O2) na aclimatação ao estresse salino com base nas alterações fotossintéticas, indicadores oxidativo e atividade enzimas antioxidativas em folhas plantas arroz. Utilizaram-se duas diferentes concentrações H2O2 (1 10 μM) para pré-tratamento, essas aplicadas solução nutritiva dois dias antes indução do (100 μM NaCl). A limitação fotossintética estomática resultante exposição NaCl foi amenizada quando as foram pré-tratadas 1...
In capitalist societies, only a single right can be fully exerted without constraints of any kind: the limitless accumulation wealth. Such imperative or prime axiom is ultimate cause raising waves inequalities observed today. this work we extended agent-based model proposed by Castro de Oliveira arXiv:1711.06164 to study effects non-uniform income redistribution policies and tax evasion on final steady-state wealth distribution economic agents. Our simulational results strongly support that...
The biochemical mechanisms underlying the involvement of cytosolic ascorbate peroxidases (cAPXs) in photosynthesis are still unknown. In this study, rice plants doubly silenced these genes (APX1/2) were exposed to moderate light (ML) and high (HL) assess role cAPXs photosynthetic efficiency. APX1/2 mutants that ML overexpressed seven five proteins involved photochemical activity photorespiration, respectively. These also increased pheophytin chlorophyll levels, but amount important for...
ABSTRACT The secretory immune response in humans infected with Giardia lamblia was studied by using saliva samples and an 8-kDa antigen capable of binding fatty acids. This not recognized from healthy individuals. may be useful diagnostic studies G. infection.
Integrative mechanisms involving photosynthetic and antioxidant protection regulated by light intensity during in vitro ex plantlets acclimatization are poorly understood. Tobacco grown under environments were exposed to different regimes evaluate the role of photosynthesis protection. In displayed a narrow capacity cope with as revealed low net CO2 assimilation (PN), decreased actual quantum efficiency photosystem II (ΦPSII) associated non-induction non-photochemical quenching (NPQ)....
The aim of this study was to test the hypothesis that salinity can affect indirectly nitrate acquisition by a negative modulation triggered glutamine accumulation. Cowpea plants were exposed mild NaCl concentration (50 mM) in order restrict growth and N-demand. After 21 d, pretreated control supplied with 0, 5 10 mM Ca(NO3)2 for 3 d absence NaCl. Salt showed great limitation NO3 -, indicated decline uptake rate, - accumulation, reductase activity protein content. restriction utilization...
We describe here a fatty acid–binding protein (FABP) isolated and purified from the parasitic protozoon Giardia lamblia. The has molecular mass of 8 kDa an isoelectric point 4.96. A Scatchard analysis data at equilibrium revealed dissociation constant 3.12 × 10−8 M when labeled oleic acid was displaced by 10-fold greater concentration unlabeled acid. Testosterone, sodium desoxycholate, taurocholate, metronidazol, α-tocopherol, together with butyric, arachidonic, palmitic, retinoic,...
A febre tifóide é uma infecção bacteriana grave e sistêmica, causada pela Salmonella typhi de distribuição global. transmissão ocorre ingestão alimentos ou água contaminados. doença comum em áreas com saneamento inadequado má higiene, afetando especialmente regiões baixo nível socioeconômico. Sem tratamento, pode ser fatal.
ABSTRACT The objective of this study was to evaluate the ecophysiological aspects and biomass production three soybean genotypes subjected soil flooding in vegetative and/or reproductive stages. design adopted completely randomized with 5 replications, a 3 x factorial arrangement, genotypes: PELBR 17-46, 15-7016, 75I77RSF IPRO; water treatment conditions: for 10 days period + period; only period, control treatment, where maintained at 70% field capacity.
