Aims: To assess the cytotoxicity, thrombolytic, anthelmintic and antioxidant activity of mehanol extract Litsea monopetala (Family: Lauraceae) leaves in laboratory using vitro methods.Methods: Cytotoxicity test was done by brine shrimp lethality bioassay where concentration 400, 200, 100, 50, 25, 12.5, 6.25, 3.125, 1.5625, 0.78125 (µg/ml). In thrombolytic performed clot lysis method 2.5, 5, 10...

in many reservoirs, after water flooding, a large volume of oil is still left behind. hot water injection is the most basic type of thermal recovery which increase recovery by improved sweep efficiency and thermal expansion of crude.in the present work, the effects of injection rate and the temperature of the injected water were surveyed by using core flooding apparatus. water flooding was perf...

OBJECTIVE This randomized crossover double-blind placebo-controlled study aimed to assess the efficacy of nateglinide (A-4166), a novel phenylalanine-derived insulin secretagogue, in type 2 diabetic subjects while fasting and 5 min before a standard meal. RESEARCH DESIGN AND METHODS A single dose of nateglinide (60, 120, or 180 mg) or placebo was given to eight diet-treated overnight-fasted t...

We have assessed the effects of intraplantar local anaesthetics (bupivacaine and lignocaine) on carrageenan-induced oedema, mechanical allodynia and spinal c-fos protein expression. Mechanical allodynia was evaluated using the vocalization threshold to paw pressure (VTPP) every 30 min until 60, 180 or 240 min after administration of carrageenan. Peripheral oedema, mechanical allodynia and spina...

Dacotah switchgrass was pretreated with sulfuric acid concentrations of 0.5, 1.0, and 2.0 wt.% at 140, 160, and 180 °C and with 1 and 3 wt.% sulfur dioxide at 180 °C over a range of times. Sulfur dioxide loadings of 0%, 1%, 3%, 5%, and 10%wt.% of dry biomass were also tested at 180 °C for 10 min. Sugar yields were tracked for pretreatment and subsequent enzymatic hydrolysis to identify conditio...

Groman, Neal B. (University of Washington, Seattle). Factors in lysis and lysis inhibition by lambda bacteriophage. J. Bacteriol. 90:1563-1568. 1965.-Induced Escherichia coli strain K-12(lambda112) exhibited lysis inhibition at 37 C but lysed at 44 C when incubated in LB medium lacking NaCl [LB - (NaCl)]. In LB medium containing NaCl, the temperatures for lysis and lysis inhibition were reverse...

The first step of bacteriophage (phage) infection is the attachment of the phage virion onto a susceptible host cell. This adsorption process is usually described by mass-action kinetics, which implicitly assume an equal influence of host density and adsorption rate on the adsorption process. Therefore, an environment with high host density can be considered as equivalent to a phage endowed wit...

When peripheral blood lymphocytes and human red cells coated with IgG were incubated in vitro in culture medium, antibody-dependent lymphocyte-mediated lysis was observed. This lysis was markedly inhibited by the addition of purified monoclonal IgG1 (1000 microgram/ml) to the culture medium. In contrast, lysis by lymphocytes of sensitized red cells in the presence of undiluted human serum was e...

We examined the effect of rate of temperature rise on the thermosensitivity of a murine lymphoblastic leukemia. L1210 cells suspended in RPMI 1630 medium:5% fetal bovine serum at pH 7.4 were heated from 37 degrees C-42 degrees C, or 44 degrees C over variable times (immediately, 30, 60, 120, 180 min) in a circulating water bath controlled by an electronic temperature programmer. Survival of the...
