Objective-This study aimed to determine the protective effects of benidipine on testicular injury after testis torsion/detorsion in ratsDesign-Experimental study Animals-Fifteen male Sprague-Dawly rats weighing 200-220g Procedure-Rats were randomly divided into 3 groups: sham (healthy group with sham operation, n=5), IRC group (control group in which I/R injury was performed by tors...

background: during the detorsion of a torsioned ovary, oxidant agents are released and melatonin as an antioxidant can reduce ischemia. we studied the histopathological changes after using melatonin on experimental torsioned ovary in cat. objective: the aim of this experimental study was to investigate the effects of melatonin on histopathological changes in torsion – detorsion injury in cat ov...

We propose a refinement of the Ray-Singer torsion, which can be viewed as an analytic counterpart of the refined combinatorial torsion introduced by Turaev. Given a closed, oriented manifold of odd dimension with fundamental group Γ, the refined torsion is a complex valued, holomorphic function defined for representations of Γ which are close to the space of unitary representations. When the re...

We consider spacetime with torsion in a Randall-Sundrum scenario where torsion, identified with the rank-2 Kalb-Ramond field, exists in the bulk together with gravity. While the interactions of both graviton and torsion in the bulk are controlled by the Planck mass, an additional exponential suppression comes for the torsion zero-mode on the visible brane. This may serve as a natural explanatio...

Neonatal testicular torsion, also known as perinatal testicular torsion is a subject of debate among surgeons. Neonatal testicular torsion either intrauterine or postnatal results into extravaginal torsion which is a different entity than intravaginal type but has the same devastating consequences if not diagnosed and managed well in time. Testicular torsion results into acute ischemia with its...

relative to a hereditary torsion theory $tau$ we introduce a dimension for a module $m$, called {em $tau$-rank of} $m$, which coincides with the reduced rank of $m$ whenever $tau$ is the goldie torsion theory. it is shown that the $tau$-rank of $m$ is measured by the length of certain decompositions of the $tau$-injective hull of $m$. moreover, some relations between the $tau$-rank of $m$ and c...

testicular scintigraphy has been well validated in the evaluation of patients with suspected testicular torsion and provides an accurate evaluation of testicular perfusion at the lime of imaging. however, the presence of normal or increased perfusion to the testis does not definitively exclude the necessity for surgical intervention. a case of intermittent testicular torsion, with a review of t...

OBJECTIVES To evaluate the effectiveness of urethral mobilisation for correcting moderate and severe penile torsion associated with distal hypospadias. PATIENTS AND METHODS Nineteen patients with distal hypospadias and congenital moderate and severe penile torsion were treated surgically. The hypospadias was at the distal shaft, coronal and glanular in seven, eight and four patients, respecti...

An electrostatic torsion micromirror is designed using the optimized spring-shaped torsion beams and U-shaped groove supporters. The main advantages of this design will be a reduction in the pull-in voltage for low-voltage applications and the function as a switch of the instability mode by adjusting the effective bending stiffness of the torsion beam. In this design, a theoretical model is dev...

OBJECTIVE To analyze the morphology of epididymis and tunica vaginalis as well as their anatomical anomalies in patients with testicular torsion. MATERIALS AND METHODS We studied 25 patients (50 testes) aged between 12 and 23 years (mean 15.6). Torsion length ranged from 2 hours to 2 days (mean 8 hours). Epididymal anatomy was classified in 6 groups: Type I--epididymis united to the testis by...
