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...
A group G is said to be of type FPoo if the ZG-module Z admits a projective resolution (Pi) of finite type (i.e., with each Pi finitely generated). If G is finitely presented, this is equivalent by Wall [5, 6] to the existence of an Eilenberg-Mac Lane complex K(G, 1) of finite type (i.e., with finitely many cells in every dimension). Up to now, all known torsion-free groups of type FPoo have ha...
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...
OBJECTIVE To investigate the relationship between objective and subjective torsion in patients with cyclovertical strabismus and determine whether objective torsion differs according to which eye is fixing. DESIGN A prospective evaluation of tests of objective and subjective torsion. PARTICIPANTS Thirty-six patients with various types of cyclovertical strabismus. METHODS Subjective torsio...
It is well-entrenched folklore that torsion gravity theories predict observationally negligible torsion in the solar system, since torsion (if it exists) couples only to the intrinsic spin of elementary particles, not to rotational angular momentum. We argue that this assumption has a logical loophole which can and should be tested experimentally. We give an explicit counterexample where a rota...
Dong, Sheng-Jing, Paul S. Hees, Wen-Mei Huang, Sam A. Buffer, Jr., James L. Weiss, and Edward P. Shapiro. Independent effects of preload, afterload, and contractility on left ventricular torsion. Am. J. Physiol. 277 (Heart Circ. Physiol. 46): H1053–H1060, 1999.—Shortening of oblique left ventricular (LV) fibers results in torsion. A unique relationship between volume and torsion is therefore ex...
background & aim: ovarian torsion is one of the most common causes of emergency surgery in gynecology, with a tendency to occur in postmenopausal women. the aim of this study was to provide information concerning the clinical presentations, surgical management, pathological findings and risk of malignancy in postmenopausal women with ovarian torsion. methods:in this cross-sectional study, the r...
in the category of mordell curves (e_d:y^2=x^3+d) with nontrivial torsion groups we find curves of the generic rank two as quadratic twists of (e_1), and of the generic rank at least two and at least three as cubic twists of (e_1). previous work, in the category of mordell curves with trivial torsion groups, has found infinitely many elliptic curves with rank at least seven as sextic tw...
Background: Management of acute abdomen usually does not necessitate accurate pre-operative diagnosis but the surgeon should make a decision about the need for emergent laparotomy. This fact is somehow different for localized peritonitis (e.g. acute appendicitis) in which the clinical presentation directs straightly to the diagnosis. However, acute appendicitis has lots of differential diagnose...
Isolated torsion of fallopian tube is an unusual event during pregnancy. Predisposing factors for torsion are hydrosalpinx, prior tubal operation, ovarian and paraovarian masses, although there maybe no obvious cause. Patient present with lower quadrant pain and diagnosis is usually made during operation for acute abdomen and salpingectomy is almost always necessary. In this report, a 24-week ...
