background : as recently some reported is investigated about relation between cold weather and testicular torsion (tt), so we decided to evaluate this hypothesis risk factor for testicular torsion in our children’s hospital. objectives : the aim of this study is to evaluate the relation between cold weather and testicular torsion in children. methods: from january 2011 todecember 2015 totally h...

abstract   background: tibial torsion is one of the torsion density which rotating in the longitudes axis of the leg. to measure this deformity, different methods such as radiographic or clinical methods were presented and introduced. methods: in this quasi-experimental study, 30 male athletes were selected randomly. their tibial torsion angle was measured using ct scan, lavand, lokomso, foot p...

the testicular torsion which is typically seen in prepuberty is very rare in the early neonatal period; prenatal diagnosis is difficult. herein, we report a five day-old male neonate with swelling and erythema of the right scrotum.  following doppler ultrasound suggestive of testicular torsion, surgical exploration was undertaken. there was gangrene of the right testis with discoloration and ne...

anandamide is an endogenous ligand for cannabinoid receptors and has endothelial protective effect against ischemic preconditioning. the purpose of this study was to investigate the effects of cannabinoids on reperfusion injury due to testicular torsion-detorsion (t/d). a total of 36 adult male sprague-dawley rats were divided into 6 groups. testicular ischemia was achieved by twisting the righ...

isolated fallopian tube torsion is rare and often difficult to diagnose. definitive diagnosis is always made at laparoscopic or via laparotomy exploration performed for suspected ovarian torsion. early diagnosis and conservative laparoscopic treatment especially in a reproductive age woman is warranted as a means of preserving fallopian tube integrity and maintaining fertility. here, we describ...

in this study, the effective parameters on the inelastic response of asymmetric buildings is evaluated for an ensemble of real iranian earthquake records by considering soil-structure interaction. then, the design eccentricity obtained from the inelastic dynamic soil-structure analysis is compared with the design eccentricity of seisimic codes of iran, atc-3, new zeland, canada, mexico, austral...

near-fault ground motions have caused very much damage in the vicinity of seismic sources during recent earthquakes. it is well known that under specific circumstances, intensive ground shakings near fault ruptures may be characterized by short-duration impulsive motions. this pulse-type motion is generally particular to the forward direction, where the fault rupture propagates towards the site...

Torsion theories are here extended to categories equipped with an ideal of 'null morphisms', or equivalently a full subcategory of 'null objects'. Instances of this extension include closure operators viewed as generalised torsion theories in a 'category of pairs', and factorization systems viewed as torsion theories in a category of morphisms. The first point has essentially been treated in [15].

wandering spleen, defined as a spleen without its usual peritoneal attachments, is a rare entity. we report a 34-year-old woman with acute abdomen due to torsion of the long vascular pedicle of a wandering spleen, displaced in the abdominal cavity, and infarction of the spleen. wandering spleen was diagnosed by ultrasound and computed tomography (ct) scan, and was managed by splenectomy in this...
