This study aimed to investigate the effects of mild salinity stress on some physiological traits and metabolic profiles rice during seedling stage. Three cultivars differing in response, ‘KDML105’ (salt-sensitive, local Thai jasmine rice), ‘IR29’ (salt-sensitive ‘Pokkali’ (salt-tolerant were subjected by flood-irrigated with 40 mM NaCl. Salinity significantly reduces growth biomass sensitive cu...

Plant survival during flooding relies on ethanolic fermentation for energy production. The available literature indicates that the first enzyme of the ethanolic fermentation pathway, pyruvate decarboxylase (PDC), is expressed at very low levels and is likely to be rate-limiting during oxygen deprivation. The authors expressed high levels of bacterial PDC in tobacco to study the modulation of PD...

In order to describe the relative predominance of lactate oxidation and fermentation under conditions of biological sulfate reduction, kinetic constants ( max and Ks) were determined. Chemostat cultures under various conditions were employed. The kinetics of sulfate reduction and lactate utilization were investigated at residence times 1 to 5 d and feed sulfate concentrations of 1.0 to 10.0 g l...

BACKGROUND Like other bacteria, Escherichia coli must carefully regulate the intracellular concentration of sodium ion (Na+). During the bacterial production of any organic acid, cations like Na+ invariably accumulate during a process which must maintain a near neutral pH. In this study, the E. coli nhaA gene encoding the Na+/H+ antiporter membrane protein and the nhaR gene encoding the NhaA re...

We have investigated the effects of exogenous addition of lactate and of the stimulation of endogenous production of lactate on protein synthesis in the anterogradely perfused rat heart. In the absence of exogenous lactate, hearts release lactate into the perfusate. At lactate concentrations of 0.2 mM and greater, the heart takes up lactate. The best fit for lactate uptake plotted against exoge...

We explored the photoreforming of rice and corn starch with simultaneous hydrogen production over a Cd0.7Zn0.3S-based photocatalyst under visible light irradiation. The was characterized by UV–vis diffuse reflectance spectroscopy, X-ray diffraction, photoelectron spectroscopy. influence pretreatment conditions, such as hydrolysis temperature alkaline concentration, on reaction rate studied. max...

The beneficial effects of high-fat, low-carbohydrate (HFLC) diets on glucose metabolismhave been questioned and its liver metabolism are not totally clear. This workaimed to evaluate the HFLC diet under different energy conditions glucosehomeostasis, fatty development hepatic gluconeogenesis using isolated perfusedrat liver. (79% fat, 19% protein, 2% carbohydrates in Kcal%) wasadministered rats...

We measured indices of energy metabolism in tissue samples taken from the interventricular septum and left ventricular free wall of open-chest dogs under control conditions and after a 20-second period of no coronary inflow. The heart was paced at 150 beats/min, and arterial pressure was controlled by aortic constriction. Each tissue sample was divided into three transmural regions and analyzed...

introduction drought stress is one of the most important abiotic stresses all around the world. the aim of breeding studies and breeding for resistance to drought is that breeders seek to identify varieties and genetic resources to drought resistant and comparison of drought resistance among the varieties and the introduction of superior varieties to farmers. drought or imbalance between supply...

Many factors impact the fluctuating rates of glucose flux and clearance in one’s daily life (meal size and composition, gastric emptying rate, physical activity, etc.). With this constantly changing need for circulating insulin abundance, it is challenging for the treatment strategy to be entirely successful in individuals with type 1 diabetes (T1D), and transient periods of hypoglycemia occur....
