Five BASIC programs to select random samples from populations or to randomize treatments are presented. Program 1 is used to obtain randomization of any number of treatments in an equal number of positions or test units for any number of replicates. Program 2 produces latin squares of any size for treatment randomization. Program 3 is used to obtain a specific number of randomly selected sample...
An experiment designed to examine food preferences of heterotrophic nanoflagellates (HNF) grazing on bacterioplankton was performed in the freshwater Rímov reservoir (Czech Republic). Water samples were size-fractionated to obtain < 5 microm filtrate containing bacteria and HNF. To manipulate resource availability, < 5 microm treatments were incubated in dialysis bags submerged in the barrels f...
The natural folate derivative, 5-methyltetrahydrofolate ([6S]-5-MTHF), could be an option for supplementation and fortification but its bioavailability remains unclear. This study compared the bioavailability of [6S]-5-MTHF with that of folic acid (FA) by measuring plasma folate responses after a single ingestion of equivalent doses of the two folate forms. In a double-blind, crossover study, 1...
Protein phosphorylation plays important roles in the mechanisms underlying serotonin (5-HT)-induced presynaptic facilitation of Aplysia sensory neurons. To study mechanisms involved in facilitation, we investigated the pattern of protein phosphorylation in sensory neurons as a function of different durations of 5-HT. Two minutes and 1.5 hr treatments with 5-HT altered the phosphorylation of 5 a...
