Odontosyllis undecimdonta is a marine syllid polychaete that produces bright internal and exuded bioluminescence. Despite over fifty years of biochemical investigation into Odontosyllis bioluminescence, the light-emitting small molecule substrate and catalyzing luciferase protein have remained a mystery. Here we describe the discovery of a bioluminescent protein fraction from O. undecimdonta, the identification of the luciferase using peptide and RNA sequencing, and the in vitro reconstruction of the bioluminescence reaction using highly purified O...

BACKGROUND: Some of the temporal variations and clock-like rhythms that govern several different health-related behaviors can be traced in near real-time with the help of search engine data. This is especially useful when studying phenomena where little or no traditional data exist. One specific area where traditional data are incomplete is the study of diurnal mood variations, or daily changes in individuals' overall mood state in relation to depression-like symptoms. OBJECTIVE: The objective of this exploratory study was to analyze diurnal variations for interest in depression on the Web to discover hourly patterns of depression interest and help seeking...

PURPOSE: Reconstruction of the anterior cruciate ligament (ACL) is the most frequently performed reconstructive surgery in the knee. Biomechanical studies have shown that double bundle (DB) reconstruction is better than single bundle (SB) reconstruction with regard to rotational stability. It is postulated that resection of ACL fibres that remain in continuity may be counterproductive for the knee as these fibres have the capacity to produce collagen. In this study, we aimed to evaluate the efficacy among selective bundle, DB and SB ACL reconstructions over a 2-year post-operative follow-up period...

There is no consensus regarding the treatment method and outcome of posterior cruciate ligament (PCL) injury. We hypothesized that although the outcome of PCL reconstruction was favorable in terms of knee stability, the outcome was unsatisfactory in terms of patient-based assessments. The purpose of this study is to evaluate the treatment outcomes of knees that underwent reconstruction for PCL injury by subjective and objective assessments, and to analyze the correlation between various assessments. Twenty-three patients who underwent PCL reconstruction were studied...

The anterior cruciate ligament reconstruction (ACLR) has become a very common surgical procedure. One of the main success indicators of the surgical procedure is the return to preinjury sporting level. In recent years, reconstructive techniques have been geared toward less morbidity and optimized ligaments process to speed up the recovery of sports activity. This study compares clinical and imaging data, to evaluate the timing of return to sport, of two populations undergoing ACLR using two different techniques: ACLR with hamstring maintaining tibial insertion (MHG) and an all-inside technique with complete hamstring detachment (DHG)...

Fingerprint Recognition System is widely deployed in variety of application domain, ranging from forensic to mobile phones. Its widespread deployment in various applications were person authentication are required, has caused concern that a leaked fingerprint template may be used to reconstruct the original fingerprint and the reconstructed fingerprint can be used to circumvent all the applications the person is enrolled. In this paper, a non-invertible fingerprint template that stores only the relative geometric information about the minutiae points is proposed...

Due to advances in neoadjuvant therapies and preoperative imaging modalities, joint-sparing resections have become appealing in bone tumor surgery. However, the intercalary reconstruction of metadiaphyseal bone defects of the femur and the tibia after juxta-articular tumor resection remains challenging. Both biological and prosthetic reconstructions have been used for joint-sparing resections, but little is known about the long-term outcome of these procedures. The authors reviewed a consecutive series of 64 patients treated with joint-sparing intercalary resection and reconstruction with bone grafts...

There have been many innovations in the field of ACL-reconstruction over the years, including the FlipCutter® and TightRope® system (both from Arthrex Inc.). The FlipCutter® is a combined guide pin and reamer that allows minimally invasive socket-creation from the inside out, especially in difficult-to-reach areas. The TightRope® is a further development of the well-known Endobutton™ (Smith & Nephew plc) that consists of a four-point knotless locking system. Its main advantage is its adjustability, which makes it possible to fill the entire bone socket with the graft without any empty space...

PURPOSE: Permanent breast seed implantation (PBSI) is a promising radiotherapy technique for early-stage breast cancer, completed in a single visit by permanently implanting 103 Pd seeds using needles inserted through a template and guided by 2D ultrasound (US). However, operator dependence has been highlighted as a limitation of this procedure. Consequently, we propose and have developed an intraoperative guidance system using 3D US and an instrumented mechanical arm to provide intraoperative 3D imaging and needle template tracking...

In inhomogeneous media, there is often a large systematic difference in the dose between the conventional Clarkson algorithm (C-Clarkson) for independent calculation verification and the superposition-based algorithms of treatment planning systems (TPSs). These treatment site-dependent differences increase the complexity of the radiotherapy planning secondary check. We developed a simple and effective method of heterogeneity correction integrated with the Clarkson algorithm (L-Clarkson) to account for the effects of heterogeneity in the lateral dimension, and performed a multi-institutional study to evaluate the effectiveness of the method...

Cancer is the second most common cause of death in our population just after cardiovascular diseases, since each third individual will become affected by it during their lifetime. Breast cancer is the most common malignancy in women. The lifetime cumulative risk of breast cancer in women under the age of 75 is around 8 % according to Czech statistics. In 70-75 % of all individuals sporadic breast carcinomas are found, with 5-10 % of all women suffer from the hereditary breast and ovarian cancer (HBOC) syndrome...

Hereditary pancreatitis (HP) is a progressive disease that can manifest in childhood with debilitating, relapsing pain. A total pancreatectomy and islet autotransplant (TPIAT) is a surgical option to relieve chronic pain while preserving the available beta-cell mass. The clinical course of HP is fraught with pancreatitis-related sequelae that can both necessitate and complicate a TPIAT. We describe a child with HP who developed a pancreatic pseudocyst-portal vein (PV) fistula. Active hemorrhage of the perforated PV into the pseudocyst and PV thrombosis complicated the planned TPIAT procedure and, preoperatively, required urgent image-guided stenting...

Anastomotic intraluminal bleeding is a well-known complication after total gastrectomy. Nevertheless, few data are published on acute bleeding obstruction pancreatitis (BOP) due to a bleeding from the jejunojejunostomy (JJ). In this paper we describe our experience. A total of 140 gastrectomies for EGJ cancer were performed in our Institute from January 2012 to January 2017. All reconstructions were performed with a Roux-en-Y anastomosis: a mechanical end-to-side esophago-jejunostomy and a mechanical end-to-side JJ...
