2 We discuss the theoretical basis for the search of the possible experimental manifestations of the torsion field at low energies. First, the quantum field theory in an external gravitational field with torsion is reviewed. The renormalizability requires the nonminimal interaction of tor-sion with spinor and scalar (Higgs) fields. The Pauli-like equation contains new torsion-dependent terms wh...

Aim The aim of the present study was to assess the protective effects of magnesium sulfate (MgSO4) on ischemia/reperfusion (I/R) induced ovarian damage in a rat ovarian torsion model. Methods Forty-two female Sprague Dawley rats were included in the study. They were divided into six groups as Group 1, sham; Group 2, bilateral ovarian torsion; Group 3, bilateral ovarian torsion-detorsion; Grou...

BACKGROUND The usefulness of T2*-weighted (T2*W) imaging for the detection of adnexal torsion has yet to be determined. PURPOSE To assess the usefulness of T2*W imaging for detecting and differentiating adnexal torsion. MATERIAL AND METHODS Eight patients with eight ovaries with torsion and 44 patients with 72 ovaries without torsion were included in this study. All patients underwent 1.5-T...

A torsion theory is called differential (higher differential) if a derivation (higher derivation) can be extended from any module to the module of quotients corresponding to the torsion theory. We study conditions equivalent to higher differentiability of a torsion theory. It is known that the Lambek, Goldie and any perfect torsion theories are differential. We show that these classes of torsio...

the omentum and the stranding continued inferiorly into left inguinal hernia sac (Fig. 2). The diagnosis of omental torsion with hernia was confirmed on laparotomy. Omental torsion usually occurs on the right side because of greater mobility of the right omentum. A left-sided omental torsion is rare and is difficult to diagnose clinically. Torsion may be primary, or secondary to underlying caus...

A language is torsion (resp. bounded torsion, aperiodic, bounded aperiodic) if its syntactic monoid is torsion (resp. bounded torsion, aperiodic, bounded aperiodic). We generalize the regular language theorems of Kleene, Sch utzenberger and Straubing to describe the classes of torsion, bounded torsion, aperiodic and bounded aperiodic languages. These descriptions involve taking limits of sequen...

We express the Burghelea-Haller complex Ray-Singer torsion in terms of the square of the refined analytic torsion and the η-invariant. As an application we obtain new results about the Burghelea-Haller torsion. In particular, we prove a weak version of the Burghelea-Haller conjecture relating their torsion with the square of the Turaev combinatorial torsion.

background: the aim of this study was to determine oxidative stress (os) parameters after testicular torsion/detorsion in adult rats. materials and methods: in this experimental study, male adult wistar rats were divided into four groups, each consisting of seven animals: group i-one hour right testicular torsion with subsequent orchiectomy, group ii-one hour right testicular torsion followed b...

OBJECTIVE Penile torsion is a counterclockwise rotational anomaly of the penile shaft or glans. We aimed to evaluate the outcomes of penile degloving and dorsal dartos flap rotation used for the repair of isolated penil torsion. MATERIAL AND METHODS During evaluation of the patients admitted to our polyclinic for circumcision between January 2013-December 2014, 5 cases of isolated penile tors...
