diabetes mellitus is one of the most common diseases affecting the endocrine system. the prevalence of diabetes mellitus will be increasing in the human population. it is a metabolic disease characterized by chronic escalation of blood glucose and disrupted metabolism of carbohydrates, fats and proteins. this was an experimental study conducted on 40 male wistar rats. this study was carried out...

Our approach is a departure from the procedures usually employed in the following important respects: (1) We recognize the typ ica l ly overlooked d is t inc t ion between lines and edges; f inding l ines offers s igni f icant simpl i f icat ions not available when searching for edges. (2) The perceptual pr imit ive we extract from the image to Indicate the local presence of l inear structure i...

BACKGROUND The blood urea nitrogen to creatinine ratio (BCR) has been used since the early 1940s to help clinicians differentiate between prerenal acute kidney injury (PR AKI) and intrinsic AKI (I AKI). This ratio is simple to use and often put forward as a reliable diagnostic tool even though little scientific evidence supports this. The aim of this study was to determine whether BCR is a reli...

HIV-1 protease (PR) is a viral enzyme vital to the production of infectious virions. It is initially synthesized as part of the Gag-Pol polyprotein precursor in the infected cell. The free mature PR is liberated as a result of precursor autoprocessing upon virion release. We previously described a model system to examine autoprocessing in transfected mammalian cells. Here, we report that a cova...

Solid-state (13)C nuclear magnetic resonance (NMR) spectra of the following intact plant tissues were recorded by the crosspolarization magic-angle spinning technique: celery (Apium graveolens L.) collenchyma; carob bean (Ceratonia siliqua L.), fenugreek (Trigonella foenum-graecum L.), and nasturtium (Tropaeolum majus L.) endosperm; and lupin (Lupinus polyphyllus Lindl.) seed cotyledons. All th...

A convenient method of preparing two- and three-coordinate Ni(I) complexes of the form L-NiI-X (L = P t Bu3, P i Pr3, DPPE, NHC; X = -N(SiMe3)(2,6- i Pr-C6H3), -O(2,6- t Bu2-4-Me-C6H2)) is reported. Protonation of the easily prepared anionic Ni(I) bis(amido) complex K{Ni[N(SiMe3)(2,6- i Pr-C6H3)]2} in the presence of an appropriate L-type ligand results in loss of HN(SiMe3)(2,6- i Pr-C6H3) and ...

We study a q-analog Qr(n, q) of the partition algebra Pr(n). The algebra Qr(n, q) arises as the centralizer algebra of the finite general linear group GLn(Fq) acting on a vector space IR q coming from r-iterations of Harish-Chandra restriction and induction. For n ≥ 2r, we show that Qr(n, q) has the same semisimple matrix structure as Pr(n). We compute the dimension dn,r(q) = dim(IR r q ) to be...

To delineate segments of the genome of the human protozoan parasite Leishmania major necessary for replication and expression, we developed a vector (pR-NEO) which can be reproducibly introduced into L. major. This DNA was derived from a 30-kilobase extrachromosomal amplified DNA bearing the dihydrofolate reductase-thymidylate synthase gene, with the coding region for neomycin phosphotransferas...
