Retroperitoneal malignant peripheral nerve sheath tumor (MPNST), a rare type of neurogenic tumor, was diagnosed in a 14-year-old girl with a history of neurofibromatosis type 1 (NF1). Immunochemistry demonstrated spindle cells positive for S-100 protein. The patient had multiple tumor recurrences and she was evaluated with serial F-18 fluorodeoxyglucose(More)
Despite of all the extensive research work done on recently developed diaryl pyrimidine analogues, thiazolidinedione analogues and indolyl aryl sulfones as HIV-1 reverse transcriptase (RT) inhibitors, there still continues the never-ending problem of resistance. In the present study, we have designed novel β-carboline analogues as inhibitor of HIV-1 RT.(More)
Plants have evolved several mechanisms in order to cope with adverse environmental conditions. The transcription factors (TFs) belonging to the DREB1/CBF subfamily have been described as major regulators of the plant responses to different abiotic stresses. This study focused on the rice gene OsDREB1B, initially described as highly and specifically induced(More)
In the present study, a new series of β-carboline derivatives were synthesized and evaluated for inhibition activity against both HIV-1 and HIV-2 strains. Among these reported analogues, surprisingly (1-phenyl-9H-pyrido[3,4-b]indol-3-yl)(4-p-tolylpiperazin-1-yl)methanone (7b), (4-(2-methoxyphenyl)piperazin-1-yl)(1-phenyl-9H-pyrido[3,4-b]indol-3-yl)methanone(More)
-Ziegler-Nichols tuned PID controller’s performances usually are not acceptable for applications requiring precise control. In this paper an improved discrete auto-tuning PID scheme is developed for DC-DC converters where large load changes are expected or the need for fast response time. The algorithm developed in this paper is used for the tuning discrete(More)
Methyl alcohol poisoning is an uncommon but an extremely hazardous poisoning. It most commonly occurs via oral ingestion of illicit or adulterated liquors or as ethanol substitution. The clinical diagnosis is made in the presence of high index of suspicion of toxic alcohol ingestion, early visual symptoms, unexplained anion gap metabolic acidosis and(More)
Endomyocardial biopsies (EMB) from patients of dilated cardiomyopathy (DCM) and normal hearts were evaluated for infiltration by lymphomononuclear cells. Cryostat sections from cases of DCM were stained with antisera against leucocyte common antigen (LCA), Pan T lymphocytes and macrophages. Paraffin sections from patients of DCM and normal hearts were also(More)
F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) has been used extensively to stage, restage, and follow neoplastic disease. However, focal accumulation of FDG may cause false-positive results in certain physiologic conditions. In this report, a unique PET and computed tomography (CT) combination scan helped define physiologic accumulation(More)
OBJECTIVE To evaluate role of dose dense neo-adjuvant chemotherapy (NACT) prior to standard concurrent chemo-radiation (CCRT) in locally advanced cervical cancer. METHODS Between June 2010 and December 2011, 28 patients (median age - 51 years, range, 35 to 67 years) with locally advanced cervical cancer received NACT using paclitaxel (60 mg/m(2)) and(More)
Plant growth and crop production are highly reduced by adverse environmental conditions and rice is particularly sensitive to abiotic stresses. Plants have developed a number of different mechanisms to respond and try to adapt to abiotic stress. Plant response to stress such as drought, cold, and high salinity, implies rapid and coordinated changes at(More)
