Atherosclerotic narrowing (stenosis) of the internal carotid artery accounts for about 10-15% of ischaemic strokes. Carotid endarterectomy (CEA) reduces the risk of stroke in patients with symptomatic stenosis and - to a lesser degree - with asymptomatic carotid stenosis. Endovascular treatment including balloon angioplasty and carotid artery stenting (CAS)(More)
Some level of trust must be established before any collaboration or interaction can take place. Since trust and privacy are closely intertwined, a mere possibility of a privacy violation reduces trust among interacting entities. This impedes sharing and dissemination of sensitive data. Affected interactions range from simple transactions to the most complex(More)
During periods of congestion, TCP flows back off and adjust the sending rate. This behavior makes TCP a conservative protocol and helps to avoid congestion collapse. Flows, like UDP, do not respond to congestion and keep sending packets. This causes other TCP flows sharing the same link to back off. Un-responsive flows waste resources by taking their shares(More)
Respiratory sensations of eight patients with mitral stenosis in response to i.v. lobeline and 6-min walk before percutaneous mitral valvulotomy (PMV) were 'being short of breath', pressure in chest, tracheo-bronchial irritation, a desire to cough, persistent dry cough, chest pain and were qualitatively similar amongst 75% (P=0.005) of the patients. A week(More)
OBJECTIVE To study the temporal relationship of smoking with electrophysiological changes. DESIGN Prospective observational study. SETTING Tertiary cardiac center. PARTICIPANTS Male smokers with atypical chest pain were screened with a treadmill exercise test (TMT). A total of 31 such patients aged 49.8±10.5 years, in whom TMT was either negative or(More)
BACKGROUND & OBJECTIVES Intraosseous (IO) access is an alternative to difficult intravenous (iv) access during emergency clinical situations. Existing IO solutions are expensive, require power supply and trained manpower; limiting their use in resource constrained settings. To address these limitations, a novel IO device has been developed. The objectives(More)
BACKGROUND & OBJECTIVES Skin is an established tissue source for cell based therapy. The hair follicle has been introduced later as a tissue source for cell based therapy. The ease of tissue harvest and multipotent nature of the resident stem cells in skin and hair follicle has promoted basic and clinical research in this area. This study was conducted to(More)
