Flooding is common in rainfed lowland areas of the world. Several physiological and biochemical plant processes were affected by the flooding, which causes deprivation of O2 in the root zone. Hence, a study was undertaken with four rice varieties, viz., Sita, IR64, FR-13A and Bharani, grown in simulated tanks and subjected to submergence stress. The effect(More)
INTRODUCTION To compare the outcomes of tubeless day care PNL using hemostatic seal in the access tract versus standard PNL. MATERIAL AND METHODS It was a prospective randomized controlled study. Cases were randomized to either the day care group with hemostatic seal (DCS) or the control group where patients were admitted and a nephrostomy tube was placed(More)
Necrotizing soft tissue infections (NSTIs) are fulminant infections of any layer of the soft tissue compartment associated with widespread necrosis and systemic toxicity. Delay in diagnosing and treating these infections increases the risk of mortality. Early and aggressive surgical debridement with support for the failing organs significantly improves the(More)
The retroperitoneum is a closed space harbouring vital organs including the great vessels, kidneys and adrenal glands, ureters, and the ascending and descending colon. Surgical management of retroperitoneal pathologies may need multiorgan resection in order to achieve complete surgical resection while preservation of surrounding organs should be attempted,(More)
Pheochromocytomas located outside the adrenal glands are called paragangliomas. A pelvic location is rare, the most common location for a paraganglioma being the retroperitoneal space. Paragangliomas arise from neural crest cells. Pelvic pheochromocytomas may mimic urinary bladder pheochromocytomas on imaging studies. Patients may present with hypertensive(More)
Fourteen rice genotypes comprising of landraces, high yielding varieties (HYVs) carrying Sub1 allele as well as without Sub1 allele contrasting in their tolerance to submergence stress were evaluated for plant survival, growth and yield response under submergence stress during kharif season of 2011 and 2012. Decline in yield was observed almost in all the(More)
A field experiment was conducted under reproductive stage drought stress condition with the objective to determine the effect of water deficit stress on yield and yield attributes of 75 rice genotypes. The effect of drought stress on various physiological and biochemical traits associated with drought tolerance was also studies at reproductive stage in(More)
Genitourinary echinococcosis is an uncommon cyclo-zoonotic disease. It is caused by Echinococcus species. Kidneys are the common target organs in the genitourinary tract. Clinical presentation is usually non-specific. Pre-operative diagnosis requires a high index of suspicion. It should be considered in differential diagnosis of cystic mass of genitourinary(More)
Both CO2 and temperature caused significant changes in crop productivity. An experiment was conducted wherein wheat was grown inside open top chambers (OTCs) in order to determine the effects of elevated atmospheric carbon dioxide (CO2) and temperature on physiology and yield attributes of wheat genotype Halna. Halna was grown with two levels of carbon(More)
Ureteric injuries, although uncommon, are a potential complication in pelvic and gynaecological surgeries and can have serious implications. The risk is mainly related to the complexity of the surgical procedure and the presence of eventual periureteric pathology. Ureteric injury during appendectomy is rare. The ureter may be damaged by laceration, being(More)
