The catabolic pathway of N-acetylglucosamine (GlcNAc) in Candida albicans is an important facet of its pathogenicity. One of the pathway genes, encoding glucosamine-6-phosphate deaminase (NAG1) is transcriptionally regulated by GlcNAc. Sequence analysis of a 4-kb genomic clone containing NAG1 indicates that this gene is part of a cluster containing two(More)
OBJECTIVE To highlight the demographic profile, various methods of self inflicted burn, and to probe into the problem by knowing various precipitating factors that may lead to self inflicted burn in our part of the country. PATIENTS AND METHODS This is a study of 154 cases of self-inflicted burns treated at the Burn Emergency Unit of Liaquat University of(More)
Fig. 10. Comparison of the voltage acceleration for the 1.5, 2.2, and 5.2 nm gate oxides from conventional-wafer-level-test conditions towards ESD breakdown times. Fig. 11. Comparison of TDB distribution for samples with and without a short-term electrical prestress. The prestress was chosen to consume a significant fraction of the effective lifetime and(More)
—This paper shows that base doping profiles obtained using any iterative scheme for reducing the base transit time in bipolar transistors for a given neutral base width must take into account the heavy doping effects implicitly. Comparing our results with those reported earlier, we demonstrate that if the heavy doping effects are not implicitly included in(More)
For nanoscale CMOS applications, strained-silicon devices have been receiving considerable attention owing to their potential for achieving higher performance and compatibility with conventional silicon processing. In this work, an analytical model for the output current characteristics (I-V) of nanoscale bulk strained-Si/SiGe MOSFETs, suitable for analog(More)
PURPOSE Vascular endothelial growth factor (VEGF)-A is an important mediator of angiogenesis in almost all solid tumors. The aim of this study was to evaluate the effect of VEGF-A expression on tumor growth, perfusion, and chemotherapeutic efficacy in orthotopic 9L gliosarcomas. EXPERIMENTAL DESIGN Stable 9L cell lines underexpressing and overexpressing(More)
Pleomorphic adenoma is the single most common salivary gland tumour. It has a diverse histological presentation because of varying proportions of different epithelial and mesenchymal elements, and presents clinically and radiologically in various ways as it occurs at many different sites in the head and neck region. The choice of imaging is influenced by(More)
The present study compares energetics of wetting behavior of crystalline and amorphous forms of a poorly water soluble drug, celecoxib (CLB) and attempts to correlate it to their surface molecular environment. Wettability and surface free energy were determined using sessile drop contact angle technique and water vapor sorption energetics was measured by(More)
PURPOSE To investigate the alterations in water-fat (W-F) ratio of the normal breast tissue of female volunteers as a function of the histological phases of the menstrual cycle. METHODS Image-guided volume localized in vivo proton ((1)H) magnetic resonance spectroscopy (MRS) at 1.5 T was carried out in the para-areolar region and the upper and lower(More)
To survey the occurrence of nodulated legumes in the arid and semi-arid areas of Western Rajasthan and to characterize their associated symbiotic bacteria. Herbaceous annual species were excavated whole, while tree species were studied as seedlings in the field or as trap plants in pot experiments. Nodules were examined by microscopy to confirm their(More)
