We consider several mechanisms that possibly affect the evolution of disk galaxies in clusters using analytical models based on a hierarchical clustering scenario. We especially focus on the evolution of disk galaxies in subclusters located around a main cluster. We show that ram-pressure stripping cannot be always ignored in subclusters, although their masses are much smaller than that of the ...

Background: Penile strangulation by various metallic and non-metallic objects poses real challenge to the physicians in the Emergency Department. The removal of the offending objects requires imaginative mind, innovative thought process, improvised skill and resources often outside the department and even outside the hospital. Cases have been reported from across the globe and among various age...

In 19 patients with closed-loop intestinal obstruction, including 16 patients with strangulating obstruction, the findings at examination with computed tomography (CT) were retrospectively correlated with the surgical and pathologic findings and evaluated by two radiologists. Signs of closed-loop obstruction, present in 15 patients, were associated with the configuration of the incarcerated loo...

Purpose: Femoral hernia is a kind of ventral hernia that surgeons commonly encounter, second in frequency only to inguinal hernia. Femoral hernias often require emergency surgery because of incarceration or strangulation of the intestine. In addition, intestinal resection may need to be considered based on intestinal viability. Definitive preoperative diagnosis and strategic planning for surger...
