Protein folding prediction even in its simplest planar HP-model has been shown to be NPcomplete, but it is still a mathematical challenge to find the hidden secret(s) of the nature to resolve the famous Levinthal’s paradox i.e., “How can a protein choose in less than a millisecond an astronomical number of possible configurations?” [1],[2]. In fact several research works have been done to find ...

Current ruminant feeding systems depend on knowledge of the composition of feeds and the rate and extent of degradation of feed organic matter (OM) and crude protein (CP) in the rumen. The effect of storage and preparation of samples on in vitro gas production and fermentation characteristics of two common forage species, namely alfalfa and ryegrass werestudied. Samples were prepared as fresh (...

Background: Akathisia is a common adverse effect of antipsychotic drugs and is characterized by subjective feelings of restlessness. First-line treatment usually consists of propranolol, a beta adrenergic antagonist. However, propranolol does not seem to be efficacious in up to 70% of patients. This study was aimed to evaluate the effect of vitamin B6 versus propranolol on antipsychotic-induced...

Incorporation of [3H]orotic acid into low-molecular-weight nRNA of rat liver, fractionated on polyacrylamide gels, increased 6-12h after partial hepatectomy and 6h after gamma-irridation at 2000 R. The incorporation of orotic acid was particularly increased into the 4.5S, 5S and approx. 10S nRNA fractions. If the irradiation was given after 6h of regeneration and RNA was isolated from the nucle...

We describe an efficient one-pot regio- and stereoselective method for synthesizing diverse 1-hydroxy-12H-6,12-methanodibenzo[d,g][1,3]dioxocines and 3-hydroxy-12H-6,12-methanodibenzo[d,g][1,3]dioxocines using ethylenediammonium diacetate (EDDA) or p-toluenesulfonic acid (PTSA) catalyzed reactions between various resorcinols and a number of 2-hydroxychalcones. These reactions involve a catalyst...

The RPCH and beta-actin cDNAs from the crayfish Cherax quadricarinatus were amplified, cloned and sequenced. The primary structure sequences of these cDNAs were compared to other members of the AKH/RPCH family. Fluctuations in the amount of the C. quadricarinatus RPCH and beta-actin mRNAs, as cDNAs, were quantified every 3h by RT-PCR. Single cosinor analysis supports the notion of beta-actin an...
