During the last decade, advancement of nanotechnology has revolutionized various fields such as electronics, optics, materials science as well as architecture, and medicine. However, their health and environmental impact is not fully understood. TiO2 and ZnO nanoparticles (NPs), which are abundantly used for commercial purposes, pose a great risk to(More)
INTRODUCTION The primary aim of this study was to evaluate the ability of radiologists to accurately estimate pneumothorax and pulmonary haemorrhage during percutaneous co-axial cutting needle CT-guided lung biopsy. METHODOLOGY Patients undergoing cutting needle lung biopsy during the study period were identified; the path taken by the cutting needle(More)
Bacteriorhodopsin functions as a light-driven proton pump in the purple membrane of Halobacterium salinarium. A variety of studies have established that a proton is transferred over an approximately 10 A distance from Asp 96 to the retinylidene Schiff base during the M --> N transition of the bR photocycle. In order to further explore the mechanism of this(More)
BACKGROUND Despite association between H. pylori and gastric neoplasm (GN) from the developed world, studies from India, where infection is more common and acquired early, are scant and contradictory. METHODS Two hundred and seventy-nine patients with GN from two northern and one eastern Indian centers during the period 1997-2005, 101 non-ulcer dyspepsia(More)
OBJECTIVE To evaluate the diagnostic efficacy of abdominal fat pad aspiration cytology as a screening procedure for systemic amyloidosis and to assess the clinical usefulness of semiquantitative grading criteria of fat pad amyloid deposits. STUDY DESIGN Aspiration cytology samples from 297 cases of abdominal fat pad were retrospectively analyzed for(More)
The 1 mm long Caenorhabditis elegans is one of the prime research tools to study different human neurodegenerative diseases. We have considered the case in which increase in the surrounding temperature of this multicellular model leads to abnormal bursts of neuronal cells that can be linked to seizure or convulsion. The induction of such seizure/convulsion(More)
BACKGROUND The etiology of malabsorption syndrome (MAS) may differ in different geographical regions. Limited data are available on the etiological spectrum of MAS among Indian adults. METHODS Ninety-nine consecutive adult patients with MAS (urine d-xylose <1 g/5 g/5 h with or without increased fecal fat (> or =7 g/24 h) were evaluated for cause of MAS(More)
INTRODUCTION No foolproof preoperative diagnostic indicators of parathyroid carcinoma (PC) exist in absence of nonskeletal metastases. Palpable parathyroid tumor, advanced skeletal and renal manifestations, and very high serum calcium and parathyroid hormone levels are considered strong predictors. Most of these features are common in Indian primary(More)
In modern times, there has been a major increase in the use of plants or herbal constituents for the prevention of age-related disorders. 4-Hydroxy-E-globularinin (4-HEG) is an iridoid and a major component of Premna integrifolia. This investigation represents a breakthrough in geriatrics by showing the longevity-promoting activity of 4-HEG in the animal(More)
Beta-caryophyllene (BCP) is a natural bicyclic sesquiterpene and is a FDA approved food additive, found as an active ingredient in essential oils of numerous edible plants. It possesses a wide range of biological activities including anti-oxidant, anti-inflammatory, anti-cancerous and local anesthetic actions. We used the well established Caenorhabditis(More)
