The role of acetolactate as a precursor in valine biosynthesis was first indicated by the isotopic studies of Strassman et al. (18) and was subsequently supported by work on valine-less mutants of Escherichia coli (21,22) and Neurospora crassa (24). The direct conversion of acetolactate to a number of valine precursors, and to valine itself, has since been demonstrated in cell-free extracts of ...

We present LODPeas: a system for browsing entities that are found to share many things in common in an RDF dataset. The system first offers standard keyword search to locate a focus entity. Once a focus entity has been found, other entities that share a lot in common with it are displayed in a graph-based visualisation. The degree to which two entities have a lot in common—their level of concur...

Parallel evolutionary algorithms (PEAs) have been studied for reducing the execution time of by utilizing parallel computing. An asynchronous PEA (APEA) is a scheme PEAs that increases computational efficiency generating new solution immediately after evaluation completes without idling computing nodes. However, because APEA gives more search opportunities to solutions with shorter times, bias ...

Indoleacetic acid (IAA) oxidase has been reported to be involved in plant growth because of its alleged role in the control of endogenous IAA levels. This purported role was reevaluated in terms of the properties and subcellular location of the enzyme in etiolated pea (Pisum sativum L. var. Alaska) epicotyls.The enzymic properties of IAA oxidase in the floating pea epicotyl segments are similar...

Two-hundred and seventeen subjects underwent transvaginal ultrasound -17 (8%) had unilateral polycystic ovary (PCO). Twelve percent of subjects with unilateral scan-pea had oligomenorrhea, 24% were amenorrheic, 23% were hirsute and 29% had acne. Biochemical parameters were compared between subjects with unilateral scan- PCO and those with bilateral scan- PCO (n=200) as well as a group of s...
