Lactobacillus casei is a useful organism for microbiologists and biochemists because it can be used in certain microbiological asays. Extensive investigations have been conducted and considerable information has been obtained concerning the nutritional requirements of this homolactic organism by measuring its growth response to various substances. On the other hand, investigations with washed c...

In rabbit platelets, the metabolically active ATP pool equilibrates with the releasable ATP pool within 1 day. The studies showing this have now been extended to human platelets. Human platelets labeled with 14C-adenosine or 14C-adenine were incubated for up to 10 hr in vitro at 37 degrees C. After 10 hr, about 12% of the total platelet 14C-ATP and 14C-ADP had become releasable with thrombin (4...

BACKGROUND Few studies have investigated live house dust mite and mite allergen removal from clothing and bedding by washing machines. No studies have investigated the transfer of mites from infested to uninfested clothing and bedding during washing. OBJECTIVE The purpose of this study was to wash different types of clothing and bedding in residential washing machines to determine the live De...

Excised apical segments of corn root (Zea mays) (5-15 mm from the root cap), some with and some without the root tips (0-5 mm) attached, were washed for varying time periods up to 4 hours in 0.5 mm CaSO(4). After washing, tips were removed from those segments washed with tips attached, and then all segments and tips were analyzed for K(+) content. The root tips (0-5 mm) initially contained abou...

ITNs are widely promoted as means of preventing manvector contact in the control of malaria. Development of Long Lasting Insecticidal Nets (LLINs) avoids the need for re-treatment which was a major operational problem faced by net owners. There are, however several factors which affect the efficacy of ITNs. Washing is one among the factors affecting the efficacy of ITNs by reducing the lethal c...

introduction: during spermiogendsis, sperm chromatin histones are replaced by protamine. after fertilization, the sprem nucleus is decondenced by glutathione (gsh). in this survey, we study the effect of various concentrations of gsh on human in vitro sperm decondensation. material and methods: after preparation and analysis of semen samples, sperm pellet was washed by ham's f-10 medium twice a...
