We report studies of the structure and packing of Langmuir monolayers LMs of polypeptide poly -4n-hexadecyloxy benzyl ,L-glutamate C16–O–PBLG on the surface of water. The molecule is a ‘‘hairy rod’’ and consists of side attachments of hexadecyloxy chains –O–C16 to the rigid rod-like core made up of -helical poly -benzyl L-glutamate PBLG . Measurements include surface pressure versus area/monome...

We explore the control of a nonholonomic robot subject to additional constraints on the state variables. In our problem, the user specifies the path of a subset of the state variables (the task freedoms xP ), i.e. a curve xP (s) where s ∈ [0, 1] is a parametrization that the user chooses. We control the trajectory of the task freedoms by specifying a bilateral time-scaling s(t) which assigns a ...

BACKGROUND Pichia stipitis xylose reductase (Ps-XR) has been used to design Saccharomyces cerevisiae strains that are able to ferment xylose. One example is the industrial S. cerevisiae xylose-consuming strain TMB3400, which was constructed by expression of P. stipitis xylose reductase and xylitol dehydrogenase and overexpression of endogenous xylulose kinase in the industrial S. cerevisiae str...

Oral naltrexone reduces heavy drinking, but is less consistent as an abstinence promoter, whereas once-monthly extended-release naltrexone (XR-NTX) also maintains abstinence. The present study sought to determine if alcohol cue reactivity is attenuated by XR-NTX. Twenty-eight detoxified alcohol-dependent adult male and female volunteers received a single i.m. injection of either XR-NTX or place...

High costs and low production efficiency are a serious constraint to bio-based xylitol production. For industrial-scale production of xylitol, a plasmid-free Escherichia coli for arabitol-free xylitol production from corncob hemicellulosic hydrolysate has been constructed. Instead of being plasmid and inducer dependent, this strain relied on multiple-copy integration of xylose reductase (XR) ge...

DESCRIPTION GLUCOPHAGE (metformin hydrochloride) Tablets and GLUCOPHAGE XR (metformin hydrochloride) Extended-Release Tablets are oral antihyperglycemic drugs used in the management of type 2 diabetes. Metformin hydrochloride (N,N-dimethylimidodicarbonimidic diamide hydrochloride) is not chemically or pharmacologically related to any other classes of oral antihyperglycemic agents. The structura...

t cells have been identified as key players in the pathogenesis of type 1 diabetes. however, the exact role of t-cell subpopulations in this pathway is presently unknown. the purpose of this study was to assess the expression pattern of two lineage-specifying transcription factors gata - 3 and t - bet , which are important in t helper type 1 (th1) and th2 cell development , respectively. gene e...
