A fraction of the low-density lipoprotein (LDL) internalized by cells via receptor-mediated endocytosis follows a short-circuit pathway, termed "retro-endocytosis," that results in the rapid exocytosis of ligand. Results from the current study suggest that retro-endocytosis of LDL in human fibroblasts is caused by resurfacing of endocytotic vesicles that contain both free and receptor-bound lig...

BACKGROUND Obstructive sleep apnoea (OSA) is one of the most common public health problems in adults. Patients with OSA are prone for excessive adipose tissue deposition in the neck, which in turn, increases the upper airway narrowing. Of the imaging modalities available for assessing the upper airway, magnetic resonance imaging (MRI) is found to be useful technique for defining soft tissue abn...

and palpable tumour at the site. Many were the opinions given as to the condition but all proved wrong. On opening the abdomen the peritoneum appeared healthy in every way and the ascending colon was resting on a boggy swelling occupying the peritoneal attachment of the colon which extended upwards and inwards to the middle line. An area to the outer side of the colon was packed off and an open...

introduction: to examine the long-term effects of normal saline and a synthetic tissue fluid (phosphate buffered saline, pbs) on mineral trioxide aggregate (mta). materials and methods: root-ends of twelve extracted human teeth were resected; root-end cavities were prepared and filled with mta. samples were randomly divided into two groups of six each. teeth in group i were placed in normal sal...

introduction: fibrolipoma, a subtype of lipoma is painless, well-circumscribed, slow-growing, submucosal benign adipocyte tumour. it is uncommon in the oral cavity and oropharyngeal region, with rare incidence in the retropharynx even rarest in pediatric age group.   case report: a very unusual case of fibrolipoma is presented in a pediatric patient, who had a huge retropharyngeal fibrolipoma a...

Applications often need to analyze past states to predict trends and support audits. Adding efficient and nondisruptive support for consistent past-state analysis requires after-the-fact modification of the data store, a significant challenge for today’s systems. This paper describes Retro, a new system for supporting consistent past state analysis in Berkeley DB. The key novelty of Retro is an...
