Folate binding activity of high affinity was identified in the particulate fractions of rat kidney homogenates. This binding activity cofractionated with alkaline phosphatase and maltase, two brush border membranes markers. With an enriched preparation of brush border membranes, freed of endogenous folate by acid treatment, the binding of [3H]olate was found to be saturable (Kb = 4.2 X 10(-11)M...

The temporal-spatial coincidence of saline deposits with rifting and alkaline magmatism has now become a commonly accepted fact. The congruency of these three phenomena implies logically, their trilateral genetic interrelation. The conventional concept for the formation of saline deposits, i.e an "evaporation process" can not be properly applied to giant saline deposits. The proposed "Volc...

The action of distilled water in producing anesthesia (loss of response to electrical stimulation) in Nitella is hastened by the addition of acid and alkali and retarded by the addition of calcium. The loss of irritability is fully reversible.

Alterations for acid and alkaline phosphatase levels and their pattern of splenic and lymph node activity in normal and virus-induced lymphoblastic leukemia were studied. Enzyme levels were examined by using both cytochemical and biochemical procedures. The GC leukemia virus, a ribonucleic acid murine virus antigenically related to the Rauscher-Moloney viruses, was used to stimulate acid and al...

background: in the present investigation radiation and cadmium induced biochemical changes in the kidney of swiss albino mice have been studied. materials and methods: for this purpose, adult male swiss albino mice (6-8 weeks old) were divided into four groups. group i (sham-irradiated), group ii (treated with cdcl2 solution 20 ppm), group iii (irradiated with 1.25, 2.5 and 5.0 gy gamma rays), ...

Lignocellulosic bioethanol is an important renewable fuel for transportation purpose. Commercial production of lignocellulosic bioethanol mainly depends on cost of cellulase production, efficient pretreatment and enzymatic hydrolysis process. In the present study cellulase production from Aspergillus niger under submerged fermentation (SmF) was optimized using coconut water as natural medium. M...

Some of the limitations a cost-effective alkaline surfactant flooding method include chemical precipitation and other formation damage issue which has greatly affected application especially in high salinity reservoirs. This study ascertains chelating attributes Ethylene-diamine-tetracetic Acid-(EDTA/NaOH), investigates ability EDTA/NaOH an anionic to improve oil recovery heavy sandstone format...

FENN, WALLACE O.,TERENCE A. ROGERSANDELEONORE A. OHR. Muscle etectrdytes in acid and alkaline solutions. Am. J. Physiol. 194(2): 373-378. [email protected] frog muscles were equilibrated in solutions of varying pH and were then analyzed for potassium, sodium and sometimes chloride, phosphate, or bicarbonate. It was found that acid applied outside the muscle causes in most cases an increased loss of...

The occurrence of both acid and alkaline ribonuclease activities in liver and kidney was reported in 1954 by Roth (1) and by de Lamirande et al. (2). Since then, investigators have used various methods to purify the intracellular ribonuclease activities (3-8). In our studies, comparatively mild procedures were used for the nuclease preparations (5)) with the hope that the nuclease activities as...
