Power management has become popular in mobile computing as well as in server farms. Although a lot of work has been done to manage the energy consumption on uniproces-sor real-time systems, there is less work done on their multi-computer counterparts. For a set of real-time tasks with precedence constraints executing on a distributed system, we propose new(More)
BACKGROUND To evaluate serum VEGF-A levels in squamous cell carcinoma of head and neck (SCCHN) patients and relationships with response to therapy. MATERIALS AND METHODS Serum VEGF-A levels in patients (n=72) treated with radiotherapy (RT) or radio-chemotherapy (RCT) and controls (n=40) were measured by ELISA. RESULTS Serum VEGF-A levels of the SCCHN(More)
Cancer stem cells (CSCs) are responsible for aggressive tumor growth, metastasis and therapy resistance. In this study, we evaluated the effects of Shikonin (Shk) on breast cancer and found its anti-CSC potential. Shk treatment decreased the expression of various epithelial to mesenchymal transition (EMT) and CSC associated markers. Kinase profiling array(More)
The Amplatzer septal occluder (ASO) is used for transcatheter closure of atrial septal defects (ASDs). This study aimed to determine the factors influencing successful closure with the ASO. A retrospective analysis of 69 patients who underwent transcatheter ASD occlusion between 2003 and 2007 was performed. The ASO was successfully implanted during 67 (97%)(More)
Proteasomes are multicatalytic protease complexes in the cell, involved in the non-lysosomal recycling of intra-cellular proteins. Proteasomes play a critical role in regulation of cell division in both normal as well as cancer cells. In cancer cells this homeostatic function is deregulated leading to the hyperactivation of the proteasomes. Proteasome(More)
Riboflavin (RF) or vitamin B2 is known to have neuroprotective effects. In the present study, we report the attenuation of the neuroprotective effects of RF under UV-B irradiation. Preconditioning of UV-B irradiated riboflavin (UV-B-RF) showed attenuated neuroprotective effects compared to that of RF in SH-SY5Y neuroblostoma cell line and primary cortical(More)
The natural polyphenolic alkanone (6)-gingerol (6G) has established anti-inflammatory and antitumoral properties. However, its precise mechanism of action in myeloid leukemia cells is unclear. In this study, we investigated the effects of 6G on myeloid leukemia cells in vitro and in vivo. The results of this study showed that 6G inhibited proliferation of(More)
The Morita-Baylis-Hillman (MBH) type reaction of a variety of aromatic and heteroaromatic conjugated nitroalkenes with formaldehyde in the presence of stoichiometric amounts of imidazole and catalytic amounts (10 mol %) of anthranilic acid at room temperature provided the corresponding hydroxymethylated derivatives in moderate to good yield. The parent(More)
In microelectronics design, power consumption, speed of operation, are crucial constraints. Propagation delay of circuit component has an impact on such factors. Pipelining and parallel processing strategies are utilized for desirable propagation delays and hence for clock and throughput variation respectively. To some extent variation in propagation delay(More)
The synthesis and SAR studies of 10 new chemical entities (NCEs) that have shown BMP-2 stimulation and osteoblast differentiation are reported. Among these, 2-((1-(benzyl(2-hydroxy-2-phenylethyl)amino)-1-oxo-3-phenylpropan-2-yl)carbamoyl)benzoic acid (11) was the most effective while its analogue 13 also showed good activity in inducing osteoblast BMP-2(More)
