Anterior cruciate ligament (ACL) reconstruction surgery has significantly evolved in recent years. This has led to development of new technologies that facilitate the diagnosis of ACL injury and the application of state of the art methods for treatment. In particular, individualized anatomical ACL reconstruction aims to restore native ACL function. Treatment is tailored to each patient based on...

We analyze pattern formation in doubly resonant intracavity second-harmonic generation in the presence of competing nondegenerate parametric downconversion. We show that for positive cavity detuning of the fundamental frequency the threshold for parametric oscillation is lower than that of transverse, pattern forming instabilities. The parametric oscillation strongly modifies the pattern dynami...

we present here a 32-year-old male with advanced lately diagnosed, right sided retroperitoneal mass, which had been already treated due to progressive muco-cutaneous lesions clinically consistent with psoriasis, during recent four years. the advanced retroperitoneal mass resected surgically and reported as hyaline-vascular castleman disease with a dense focus of coarse calcification, on histopa...

Percutaneous pulmonary balloon valvuloplasty (PBV) remains the treatment of choice for pulmonary stenosis (PS). This procedure is effective, safe and gives excellent results. Pulmonary artery (PA) dissection is a rare complication of PBV. This report is a case of an asymptomatic 17-year-old male with a history of PBV due to severe PS dating back to fifteen years ago. During recent echocardiogra...

background: in most armies, clothes, equipment and weapons are designed according to the physical characteristics and anthropometric data of soldiers. objective: to study the anthropometric characteristics of iranian army force and their changes over recent years. methods: 12 635 iranian military personnel aged between 18 and 30 years with tenure of <10 years who were normally engaged in educat...

sperm cells are one of the most stellar and fas-cinating cells in all species. one of the most distinctive characteristic of these cells is their movement dynamics which can be observed through a light microscope. the first paper regarding sperm cell biology that appeared on pubmed was pres-ented by dr. w.f. whitney (1). there, he showed the staining properties of spermatozoa and it was publish...
