C57BL/6J-Min/+mice (n = 56), heterozygous for a nonsense mutation in the Apc gene, were randomized at weaning to seven groups, including groups treated with piroxicam at 0, 50, 100, and 200 ppm in the AIN93G diet. After only 6 weeks of treatment, intestinal adenomas and aberrant crypt foci were counted, and serum levels of piroxicam and thromboxane B2 were(More)
Urinary bladder cancer (UBC) is a common disease worldwide with a higher incidence rate in developed countries. Organochlorine pesticides (OCPs), potent endocrine disrupters, are found to be associated with several cancers such as prostate, breast, bladder, etc. Glutathione S-transferase (GST) is a polymorphic supergene family involved in the detoxification(More)
Research and innovation in teaching and learning are prime topics for the Journal of Instructional Technology and Distance Learning (ISSN 1550-6908). The Journal was initiated in January 2004 to facilitate communication and collaboration among researchers, innovators, practitioners, and administrators of education and training involving innovative(More)
Sub-40 nm size ordered nanodroplet arrays of polystyrene are fabricated by a low dose selective electron beam exposure of an ultrathin polymer film followed by its intensified self organized dewetting under a mixture of water and polar organic solvents. The self organization speeds up patterning and reduces the feature size, both by more than 10 times.(More)
We present the Spitzer Extragalactic Representative Volume Survey (SERVS), an 18 deg 2 medium-deep survey at 3.6 and 4.5 µm with the post-cryogenic Spitzer Space Telescope to ≈ 2 µJy (AB = 23.1) depth of five highly observed astronomical fields (ELAIS-N1, ELAIS-S1, Lockman Hole, Chandra Deep Field South and XMM-LSS). SERVS is designed to enable the study of(More)
Paragangliomas are extra-adrenal tumours of the autonomic nervous system, which rarely present as primary retroperitoneal mass mimicking pancreatic malignancy (incidence 2-8 per million populations). Urinary Bladder Paraganglioma are also extremely rare (0.06% of all Bladder Tumour and 6% of Paragangliomas) with most being malignant and high grade tumours.(More)
Dewetting of ultrathin (< 100 nm) polymer fi lms and their self-organization on physicochemically patterned substrates has been extensively studied with a view to potential applications in soft-patterning. [ 1 ] However, despite their scientifi c and technological promise, there are two major limitations for self-assembled patterns: (1) The length scale of(More)
Tumor lysis syndrome is a potentially life threatening condition which is most commonly encountered in patients being treated with chemotherapy. We report a case of spontaneous tumor lysis syndrome that developed intraoperatively in a patient with undiagnosed Burkitt's lymphoma. Characteristic electrolyte disturbances and white emulsion like urine following(More)
A simple and novel method to fabricate and miniaturize surface and subsurface microstructures and micropatterns in glassy carbon is proposed and demonstrated. An aqueous resorcinol-formaldehyde (RF) sol is employed for micromolding of the master pattern to be replicated, followed by controlled drying and pyrolysis of the gel to reproduce an isotropically(More)
