The antiphagocytic capsule of Bacillus anthracis is a major virulence factor. We hypothesized that it may also mediate virulence through inhibition of the host's immune responses. During an infection, the capsule exists attached to the bacterial surface but also free in the host tissues. We sought to examine the impact of free capsule by assessing its effects on human monocytes and immature den...
OBJECTIVES The purpose of this study was to compare the thickness of the hip capsule in patients with surgical hip disease, either with cam-femoroacetabular impingement (FAI) or non-FAI hip pathology, with that of asymptomatic control hips. METHODS A total of 56 hips in 55 patients underwent a 3Tesla MRI of the hip. These included 40 patients with 41 hips with arthroscopically proven hip dise...
OBJECTIVES To evaluate the effectiveness of capsule endoscopy in the management of patients with obscure gastrointestinal bleeding. METHODS A prospective descriptive study was conducted at surgical unit IV, Civil Hospital Karachi over a period of 2 years from December 2007 to November 2009. Twenty eight consecutive patients presenting with obscure gastrointestinal bleeding were included in th...
The properties of purified capsular polysaccharide from the cyanobacterium Microcystis flos-aquae C3-40 were examined by capillary viscometry. Capsule suspensions exhibited similar viscosities between pH 6 and 10 but were more viscous at pH <=4 than at pH 6 to 11. At pH 7, a biphasic effect of metal ion concentration on capsule viscosity was observed: (i) capsule viscosity increased with increa...
