Background: Several endometriosis classification systems have been proposed and published but the search for a universal language that communicates the complexity, laterality and severity of this disease continues. The authors introduce the Visual-Numeric Endometriosis Scoring System. VNESS is a novel system for describing surgical findings in each compartment of the pelvis in a way that is simple to use, visually intuitive and mirrors a laparoscopic image of the pelvis.

This then raises the possibility that the SCR may be having unintended consequences on glenohumeral kinematics. The purpose of this study was to quantify the glenohumeral joint kinematics following Fascia Lata SCR (FL-SCR).

Background: The restriction of active internal rotation (IR) after reverse shoulder arthroplasty (RSA) poses a challenging problem for reconstructive shoulder surgeons, particularly in patients suffering from massive rotator cuff tears (mRCT) with subscapularis (SSC) deficiency. This study aims to evaluate the biomechanical effectiveness of different tendon transfer techniques following medialized glenoid and lateralized humerus RSA in improving internal rotation (IR) strength.
Methods: Eight cadaveric shoulder specimens were evaluated using a custom shoulder testing system designed to simulate loading conditions typical of mRCT with SSC insufficiency.
Quantum-dot (QD) light-emitting diodes (QLEDs) are garnering significant attention owing to their superb optoelectrical properties, but the overinjection of electrons compared to holes into the emissive layer (EML) is still a critical obstacle to be resolved. Current approaches, such as inserting a charge-balancing interlayer and mixing p-type organic additives into the EML, face issues of process complexity and poor miscibility. In this work, we demonstrate efficient InP QLEDs by simply embedding NiO nanoparticles (NPs) into the EML which forms a homogeneous QD-metal oxide hybrid EML.

Silicon (Si) anodes have long been recognized to significantly improve the energy density and fast-charging capability of lithium-ion batteries (LIBs). However, the implementation of these anodes in commercial LIB cells has progressed incrementally due to the immense volume change of Si across its full state-of-charge (SOC) range. Here, we report an anode-tailored full-cell design (ATFD), which incorporates micrometer-sized silicon (μ-Si) alone, for operation over a limited, prespecified SOC range identified as 30-70%.
