A self-induced, non-traumatic testicular torsion is a rare entity that to our knowledge has not been reported in the literature. We report the case of a 28-year-old male who caused a self-induced testicular torsion during acts associated with cross dressing. Differential diagnosis of the acute scrotum in an adult should always include testicular torsion, as outcomes in this population are worse...

extract  in this study, position of fetus were examined in the different weeks of pregnancy and their association with fetus presentation in during labor. the study group included women who had normal condition. the aim of this study include:   1- to determine the distribution normal position of fetus before birth.   2- to determine the possibility of concurrent position of fetus in during preg...

An approximation technique is introduced that greatly facilitates the estimation of the Epidemic-Type Aftershock Sequence (ETAS) model introduced by Ogata (1988), which is widely used to describe earthquake catalogs. The proposed approximation greatly simplifies the integral term in the log-likelihood, the computation of which is by far the greatest hurdle in maximum likelihood estimation. The ...

We show how active transport of ions can be interpreted as an entropy facilitated process. In this interpretation, the pore geometry through which substrates are transported can give rise to a driving force. This gives a direct link between the geometry and the changes in Gibbs energy required. Quantifying the size of this effect for several proteins we find that the entropic contribution from ...

We describe here a transposon-based DNA sequencing strategy that allows the introduction of sequencing priming sites throughout a target sequence by bacterial mating. A miniplasmid was designed to select against transposon insertions into the vector. Sites of transposon insertion are mapped by the polymerase chain reaction with bacterial overnight cultures providing the templates. A small set o...

Identification of fetal chromosomal aneuploidy is a predominant reason for pregnant women to undergo prenatal testing, most of which are invasive and carry a risk for fetal loss. The presence of fetal DNA in maternal circulation has offered an opportunity for non-invasive prenatal detection [1]. However, this fetal DNA exists only as a minor fraction among the co-existing background of maternal...

Background. Excimer laser coronary angioplasty has been reported to be a promising treatment for complex coronary artery disease. The purpose of this study was to define the predictors of acute success and restenosis after this experimental intervention. Methods and Resuls. A cohort of 200 consecutive patients had a minimum of 6 months of follow-up evaluation after treatment of 215 coronary ste...

We introduce a class of facilitated asymmetric exclusion processes in which particles are pushed by neighbors from behind. For the simplest version in which a particle can hop to its vacant right neighbor only if its left neighbor is occupied, we determine the steady-state current and the distribution of cluster sizes on a ring. We show that an initial density downstep develops into a rarefacti...
