OBJECTIVE: Video-assisted thoracoscopic surgery (VATS) has become the standard treatment method for primary spontaneous pneumothorax. Concerns about lesser pain and better cosmesis led to the evolution of uniportal access. This study prospectively compared the results of the uniportal, two-port, and three-port thoracoscopic surgery. MATERIAL AND METHODS: One hundred and thirty-five patients were randomized into three groups according to the port numbers. The groups were compared regarding the operation time, hospital stay, amount of drainage, area of pleurectomy, complications, recurrences, and pain scores...

Single-incision approach in robotic gynecology is a relatively new concept. The role of single-port systems in robotic hysterectomy, their advantages and disadvantages, as well as the technical challenges, are still under investigation. A systematic review was performed by searching in PubMed and Scopus databases. In 810 out of 1225 patients, hysterectomy was performed for non-neoplastic disease. Single-Site ® was the most common port system. Duration of the procedure and relative blood loss ranged from 60 to 311 min and 7 to 750 ml, respectively...

Tunneled central venous catheters with ports are increasingly used for therapeutic apheresis procedures. Vortex ports have been used as access for therapeutic apheresis procedures, but are not ideal for therapeutic plasma exchange (TPE) procedures due to lower flow rates. We performed an in vitro experiment to compare flow characteristics of the single-lumen Vortex port (AngioDynamics) with the single-lumen TidalPort (Norfolk Medical). We used expired red blood cell units and adjusted the hematocrit to 40% with normal saline in a 2-L bag...

Ionizing radiation (IR)-induced damage confers functional and conformational changes to nuclear chromatin associated with DNA single and double strand breaks. This leads to the activation of complex DNA repair machineries that aim to preserve the integrity of the DNA molecule. Since hetero- and euchromatin are differentially accessible to DNA repair pathways, local chromatin re-arrangements and structural changes are among the consequences of an activated DNA damage response. Using super-resolution localization microscopy (SRLM), we investigated the X-ray-induced repositioning of γ-H2AX and histone H3K9me3 heterochromatin marks in the nuclei of HeLa cells...

There are numerous surgical approaches for the treatment of pericardial effusions but no clear consensus of best management. We present a 44-year-old woman with metastatic breast cancer presenting with a new 2-cm pericardial effusion on ultrasound. In light of the patient's palliative condition and the urgent need for chemotherapy, careful consideration was made for her surgical drainage of the pericardial effusion. Because of the patient's medical comorbidities, a general anesthetic was deemed not to be in the patient's best interest...

Topological insulators are phases of matter characterized by topological edge states that propagate in a unidirectional manner that is robust to imperfections and disorder. These attributes make topological insulator systems ideal candidates for enabling applications in quantum computation and spintronics. Here, we propose a fundamentally new concept that exploits topological effects in a unique way: the topological insulator laser. These are lasers whose lasing mode exhibits topologically-protected transport without magnetic fields...
