Rapid eye movement sleep in males is characterized by penile erection along with EEG desynchronization, muscle atonia, ponto-geniculo-occipital waves, and rapid eye movements (REM). The central neural mechanisms regulating sleep related erections (SREs) are not known. Recently, the lateral preoptic area has been shown to contribute in sleep-related erectile mechanisms. The present study was con...

Cytokinesis in budding yeast is accomplished by the concerted action of actomyosin ring function and septum formation. The actomyosin ring is not essential for cell viability, but it is required for efficient cell division. Deletion of the actomyosin ring results in abnormal septum formation, and a delay in cytokinesis and cell separation. In contrast, septum formation is essential for cell via...

BACKGROUND Septate uterus is the most common uterine anomaly and a cause for miscarriage and infertility. Existing data suggested a better reproductive outcome of uterine septum following hysteroscopic septum resection. OBJECTIVE Current study was administered to share our experience in hystroscopic septum resection for reproductive outcome following hysteroscopic treatment of uterine septum ...

OBJECTIVES Surgical closure of some muscular ventricular septal defects has been proven to be difficult. In order to simplify the surgical technique we have used intraoperatively Rashkind double umbrella devices to occlude muscular ventricular septal defects. METHODS On the basis of haemodynamic and echocardiographic study five children aged 4, 6, 7, 14 and 41 months were considered suitable ...

In Mycobacterium tuberculosis the mechanism of septum formation and regulation of cell division remains undefined. In other bacterial species FtsZ polymerization and septum formation are influenced through protein interactions in addition to transcriptional regulation, and the combination of these provides tight regulation of this process. However, homologues of proteins known to affect FtsZ as...

BACKGROUND Abnormally large cavum septum pellucidum has been reported in posttraumatic stress disorder; however, the origin of this association is uncertain. METHODS We utilized magnetic resonance imaging to measure cavum septum pellucidum in pairs of identical twins discordant for combat exposure in Vietnam. RESULTS Presence of abnormal cavum septum pellucidum was significantly correlated ...

For the understanding of the developmental significance of various parts of the normal ventricular septum, 54 normal human embryos and 154 mature heart specimens showing different types of VSD’s and AV canal malformation were studied. The pars interventriculare of the septum membranaceum is derived primarily from the right superior and inferior tubercies of the AV cushions. The pars atrioventri...

abstract objective autosomal recessive spinal muscular atrophy (sma) is, after cystic fibrosis, the second most common fatal monogenic disorder and the second most common hereditary neuromuscular disease after duchenne dystrophy. the disease is characterized by degeneration of anterior horn cells leading to progressive paralysis with muscular atrophy. depending on the clinical type (werdnig- ho...

duchenne muscular dystrophy (dmd) and the milder allelic becker muscular dystrophy (bmd) are x-linked disorders. both dmd & bmd result from heterogenous mutation in the dystrophin gene and in about 65% of the cases one or more exons of the gene are deleted or duplicated. one third of cases arise from new mutation and the rest are familial. to analyze the prevalence of deletion in iranian patien...
