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 the projects Smartblades and 2 a full-scale 20 m rotor blade for NREL CART3 wind turbine was designed, built tested. The intended to have strong bending–torsion coupling. By means of experiments, proof technology in question supposed be provided. experimental work accompanied by simulations. aim paper describe publish reference finite element model blade. validation procedure is presented, a...

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...

INTRODUCTION The mechanical characterization of soft biological tissues is essential to a number of medical applications, such as surgery planning, surgical training deploying virtual reality based simulators, or diagnosis. Quantitative data sets are available on the in-vivo mechanical properties of soft tissues in animal organs, but very limited data are available on the behavior of soft tissu...

In this paper, a new three-axis electromagnetically actuated micromirror structure has been proposed and fabricated. It is electromagnetically actuated at low voltage using an external magnetic field. The main purpose of this work was to obtain a three-axis actuated micromirror in a mechanically robust structure with large static angular and vertical displacement at low actuation voltage for fi...

We report computation results obtained from extensive coarse-grained molecular-dynamics simulations of amorphous ensembles of polymer chains at constant density. In our polymer model, we use bending and torsion potentials acting along the polymer backbone to control the chain stiffness. The static and dynamic properties of the polymer bulk have been analyzed over a large temperature interval in...
