Background: Acetabular Retroversion (AR) is a hip disorder and one of the causes of pain in this area. Evaluationof positive Cross Over Sign (COS) on AP X-Rays of the hip is currently the best method of diagnosis of AR. Severalstudies have measured co-existence of Ischial Spine Sign (ISS) in patients with AR. In this study we evaluated thediagnostic value of ISS in confirmation of AR and compar...

Background: To determine whether random-start controlled ovarian stimulation (COS), in which a stimulation is performed regardless to day of patient’s menstrual cycle, has similar outcomes in comparison to conventional early follicular phase-start COS for cryopreservation of fertilized oocytes in cancer patients. Materials and Methods: This prospective study was performed at two infertility cen...

The generation of mature and vascularized human pluripotent stem cell-derived cardiac organoids (hPSC-COs) is necessary to ensure the validity drug screening disease modeling. This study investigates effects cellular aggregate (CA) stemness self-organization on hPSC-COs elucidates mechanisms underlying organoid (CO) maturation vascularization. COs derived from 2-day-old CAs with high (H-COs) 5-...

Abstract. Sulfate geoengineering (SG) methods based on lower stratospheric tropical injection of sulfur dioxide (SO2) have been widely discussed in recent years, focusing the direct and indirect effects they would climate system. Here a potential alternative method is discussed, where emissions are located at surface or troposphere form carbonyl sulfide (COS) gas. There two time-dependent chemi...
