Nowadays, the fast and sensitive high-performance liquid chromatographic (HPLC) analysis of derivatized amino acids is a good alternative to the ion-exchange chromatography (IEC) method for plasma amino acids. However, several precautions have to be taken in order to obtain reliable data on the concentration of amino acids in physiological fluids. These include the collection, centrifugation, s...

The aim of this work was the preparation and characterization of a pro-prodrug able to simultaneously transport silybin, a drug possessing various pharmacological effects, and trans-ferulic acid, a known antioxidant. More specifically, l-phenylalanine-N-(4-hydroxy-3-methoxy-phenyl) prop-2-en-O-(2R,3R)-3,5,7-trihydroxy-2-((2R,3R)-3-(4-hydroxy-3-methoxyphenyl)-2-(hydroxymethyl)-2,3-dihydro-benzo-...

Short amino acid sequence patterns, called motifs, play an important role in molecular biology research. While a number of tools for locating motifs in sequence databases have been developed, no existing tool performs fast enough to allow interactive searching of entire databases. Interactive searching enables biologists to explore the effects of changes to a motif on the set of sequences match...

INTRODUCTION Maturity-onset diabetes of the young (MODY) is a heterogenous group of disorders characterized by an early onset of insulin-independent diabetes mellitus, an autosomal dominant mode of inheritance and a primary defect in beta-cell. There are six subtypes of MODY. MODY2 and MODY3 are the most frequent. CASE OUTLINE We present a nine-year-old boy with intermittent hyperglycaemia. A...

Studies on cold acclimation of insects including s ilkworms have shown significant variations in the levels of various biomolecules to cope with thermal shock. The present study has been carried out on cold-stressed larvae of Daba Trivoltine (TV) of tasar silkworm, Antheraea mylitta Drury to analyze the mortality rate, variations in the biomolecules and excretory products at varied durations. T...

We have sequenced a DNA fragment containing the Escherichia coli thrA-thrB junction, the complete thrB gene and the thrB-thrC junction. The intergenic sequence thrA and thrB is only one base pair. The coding region for homoserine kinase is 927 base pairs long. It is followed by 114 base pair segment in an open reading frame predicting that thrC begins just after non-sense codon of thrB. The pre...

Prostate cancer (PCa) is the most frequently diagnosed cancer and the third highest cause of cancer-related deaths in men in the U.S. The development of chemotherapeutic agents that can bind PCa tumor cells with high specificity is critical in order to increase treatment effectiveness. Integrin receptors and their corresponding ligands have different expression patterns in PCa cells. They have ...
