Torsion of the gallbladder with gangrene is a rare condition which is generally due to an abnormal anatomical variation of the organ i.e., loss of fixation of the organ to the inferior margin of the liver and the presence of a long meso cyst. The case considered is a seven year old boy who presented with acute abdominal pain. He underwent laparotomy 36 hours after having sustained blunt ab...

Tibial torsion, twisting of the tibia about its longitudinal axis, varies during development and early childhood. Knowledge of the normal range of tibial torsion at various ages and its accurate clinical measurement is important in the assessment of the extent of a torsional deformity. To evaluate tibial torsion a reliable technique for its measurement in vivo is therefore required. The aim of ...

The motion of a conducting electron in a quantum dot with one or several dislocations in the underlying crystal lattice is considered in the continuum picture, where dislocations are represented by torsion of space. The possible effects of torsion are investigated on the levels of classical motion, nonrelativistic quantum motion, and spin-torsion coupling terms derivable in the non-relativistic...

background: proanthocyanidin is a potent bioactive antioxidant naturally occurring in grape seed and acts as reactive oxygen species (ros) scavenger. the aim of this study was to investigate the effects of proanthocyanidinin in experimental ovarian torsion injury.   methods : twenty four rats were randomly divided into three groups (n=8). group 1: the laparotomy group, group 2: ovarian torsion ...

omental torsion is caused by the rotation of the greater omentum on its axis which may lead to tissue infarction and necrosis. it is a rare cause of acute abdomen. signs, symptoms and paraclinical data are not specific. the patients usually undergo laparotomy for acute abdomen of poorly defined origin. high index of suspicious is required for the diagnosis of this entity. the diagnosis is usual...

We generalize to higher algebraic $K$-theory an identity (originally due Milnor) that relates the Reidemeister torsion of infinite cyclic cover its Lefschetz zeta function. Our involves a invariant, endomorphism torsion, parametrized family endomorphisms as well function such family. also exhibit several examples families having non-trivial torsion.

BACKGROUND To determine if asymmetric ovarian edema on non-contrast MRI can be used to distinguish torsed from non-torsed stimulated ovaries in pregnant women. METHODS In this retrospective study, our radiology database was searched for women who were pregnant and who had undergone ovarian stimulation and underwent MRI abdomen/pelvis from 1/2000-12/2012. At our institution, ultrasound is typi...

The trace anomaly induced dynamics of the conformal factor is investigated in four-dimensional quantum gravity with torsion. The constraints for the coupling constants of torsion matter interaction are obtained in the infrared stable fixed point of the effective scalar theory. ⋆ On leave from Pedagogical Institute, 634041 Tomsk, Russia In a recent paper [1] the trace anomaly induced dynamics of...
