Periventricular Microglial Cells Interact with Dividing Precursor Cells in the Nonhuman Primate and Rodent Prenatal Cerebral Cortex.

J Comp Neurol 2018 Dec 15. Epub 2018 Dec 15.

Department of Pediatrics, School of Medicine, UC Davis, Davis, CA.

Cortical proliferative zones have been studied for over 100 years, yet recent data has revealed that microglial cells constitute a sizeable proportion of ventricular zone cells during late stages of cortical neurogenesis. Microglia begin colonizing the forebrain after neural tube closure and during later stages of neurogenesis populate regions of the developing cortex that include the proliferative zones. We previously showed that microglia regulate the production of cortical cells by phagocytosing neural precursor cells (NPCs), but how microglia interact with NPCs remains poorly understood.

Duke University, Mechanical Engineering and Materials Science Dept., Durham, NC, USA.

Experiments with evaporation of capillary bridges between two glass spheres show that the bridge gorge radius decreases much faster than the contact radius, distorting the original constant mean curvature bridge shape. In addition, the Laplace pressure calculated from local principal curvatures exhibits high gradients along the bridge moving external surface, most commonly with a high suction near the triple phase contact and positive pressure near the gorge. The high suction results from a negative external curvature at contact. Read More

Structural Evidence for Product Stabilization by the Ribosomal mRNA Helicase.

RNA 2018 Dec 14. Epub 2018 Dec 14.

University of California Santa Cruz

Protein synthesis in all organisms proceeds by stepwise translocation of the ribosome along messenger RNAs (mRNAs), during which the helicase activity of the ribosome unwinds encountered structures in the mRNA. This activity is known to occur near the mRNA tunnel entrance, which is lined by ribosomal proteins uS3, uS4, and uS5. However, the mechanism(s) of mRNA unwinding by the ribosome and the possible role of these proteins in the helicase activity are not well understood. Read More

Compatibility of CO laser surgery and fluorescence detection in head and neck cancer cells.

Head Neck 2018 Dec 14. Epub 2018 Dec 14.

Department of Otorhinolaryngology and Head and Neck Surgery, Radboud University Medical Center, Nijmegen, The Netherlands.

Background: Surgical treatment of cancer requires tumor excision with emphasis on function preservation which is achieved in (early stage) laryngeal cancer by transoral carbon dioxide (CO ) laser surgery. Whereas conventional laser surgery is restricted by the surgeon's visual recognition of tumor tissue, new approaches based on fluorescence-guided surgery (FGS) improve the detection of the tumor and its margin. However, it is unclear whether fluorophores are compatible with high-power laser application or whether precision is compromised by laser-induced bleaching of the dye. Read More

Ultrahigh-Sensitive Broadband Photodetectors Based on Dielectric Shielded MoTe /Graphene/SnS p-g-n Junctions.

Adv Mater 2018 Dec 14:e1805656. Epub 2018 Dec 14.

Department of Physics, Southern University of Science and Technology, Shenzhen, 518055, China.

2D atomic sheets of transition metal dichalcogenides (TMDs) have a tremendous potential for next-generation optoelectronics since they can be stacked layer-by-layer to form van der Waals (vdW) heterostructures. This allows not only bypassing difficulties in heteroepitaxy of lattice-mismatched semiconductors of desired functionalities but also providing a scheme to design new optoelectronics that can surpass the fundamental limitations on their conventional semiconductor counterparts. Herein, a novel 2D h-BN/p-MoTe /graphene/n-SnS /h-BN p-g-n junction, fabricated by a layer-by-layer dry transfer, demonstrates high-sensitivity, broadband photodetection at room temperature.

Fruitful first experience with an 8K ultra-high-definition endoscope for laparoscopic colorectal surgery.

Asian J Endosc Surg 2018 Dec 13. Epub 2018 Dec 13.

Department of Gastrointestinal Surgery, St. Luke's International Hospital, Tokyo, Japan.

We performed laparoscopic surgery for three cases of colorectal cancer using an 8K ultra-high-definition endoscopic system, which offers 16-fold higher resolution than the current 2K high-definition endoscope. The weight of the camera has been successfully reduced to 370 g. To maximize the advantages of the 8K ultra-high-definition endoscope, surgery was performed by darkening the room and placing a large 85-in. Read More

Safe and easy technique for the laparoscopic application of Seprafilm® in gynecologic surgery.

Asian J Endosc Surg 2018 Dec 13. Epub 2018 Dec 13.

Department of Obstetrics and Gynecology, School of Medicine, Keio University, Tokyo, Japan.

Introduction: Laparoscopic surgery is a minimally invasive surgery, and the rate of postoperative adhesions is low. Although Seprafilm® helps to reduce adhesions, its application in the abdominal cavity during laparoscopic surgery is difficult because of its material. Therefore, we propose an easy method for applying this adhesion barrier. Read More
