We consider axial torsion fields which appear in higher derivative quantum gravity. It is shown, in general, that the torsion field possesses states with two spins, one and zero, with different masses. The first-order formulation of torsion fields is performed. Projection operators extracting pure spin and mass states are given. We obtain the Lagrangian in the framework of the first order forma...

Testicular torsion is one of the main causes of acute scrotum and may result in permanent damage of the testicular tissue. Color Doppler imaging has been frequently used in the diagnosis of testicular torsion and posttreatment follow-up period of the disease. There are some studies reporting the value and usefulness of diffusion-weighted imaging in the diagnosis of testicular torsion. However, ...

PURPOSE The hypothesis of association between testicular torsion and hyperactive cremasteric reflex, worsened by cold weather, has not been proved. Thirteen studies in the literature evaluated this issue, with inconclusive results. The aim of the present study was to evaluate the seasonality of testicular torsion in a large subset of patients surgically treated in Brazil, and additionally to es...

OBJECTIVE To determine if left ventricular torsion, as measured by magnetic resonance tissue tagging, is afterload dependent in a canine isolated heart model in which neurohumoral responses are absent, and preload is constant. METHODS In ten isolated, blood perfused, ejecting, canine hearts, three afterloads were studied, while keeping preload constant: low afterload, high afterload (stroke v...

Concept of ventricular torsion has long history and valuable concepts were established for ventricular torsion contributing to left ventricular (LV) diastolic relaxation and early diastolic filling to generate rapid " suction " power during diastole. However, ventricular torsion had been recognized as only interesting research tools for clinicians because of hard to assess the ventricular torsi...

We presented a case of penile torsion due to previous hypospadias surgery. A patient applied to our clinic for treatment of hypospadias fistula and accompanying penile torsion. Patient’s urethral fistula was repaired first and penile torsion was corrected in the second stage due to multiple fistula tracts. Proximal based flip flap technique was used for closure of the fistula and simple deglovi...

Torsion appears in a natural way in modern formulations of the gravitational theories. In this work we study several aspects of the interplay between the Standard Model and a classical gravitational background with torsion. In particular we consider the problem of the gauge and gravitational anomalies, B and L anomalies, the effective action for the torsion and the propagation of electromagneti...

A retrospective study of 46 patients who presented with proved testicular torsion over five years at two Dublin hospitals showed that in 40 cases torsion had occurred when the temperature was under 2 degrees C; the incidence of torsion was higher during the cold months of the year. Both of these findings were statistically significant. These and other results suggest that the ambient temperatur...

The acute scrotum syndrome is a medical-surgical emergency and the recognition of this condition by both healthcare professionals and the general population may result into the patients' coming in earlier for medical examination and into the preservation of the gonad in case of torsion. The purpose of this retrospective analytical research is to point out specific epidemiological aspects in ped...
