5-Hydroxymethylcytosine (5hmC) is a modified form of cytosine, which has recently been found in mammalian cells and tissues. 5hmC is derived from 5-methylcytosine (5mC) by Ten-eleven translocation (TET) family protein-mediated oxidation and may regulate gene expression. Numerous affinity-based profiling methods have been developed to help understand the exact function of 5hmC in the genome. However, these methods have a relatively low resolution (~100 bp) without quantitative information of the modification percentage on each site...

BACKGROUND: Robot-assisted retrohepatic inferior vena cava (IVC) thrombectomy (RA-R-IVCTE) has been reported only for limited series. OBJECTIVE: To describe in detail the techniques for RA-R-IVCTE with regard to the relationship of a proximal thrombus to either the first porta hepatis (FPH) or second porta hepatis (SPH). DESIGN, SETTING, AND PARTICIPANTS: From May 2013 to July 2016, 22 patients with R-IVC tumor thrombi were admitted to our hospital...

OBJECTIVES: The standard treatment for FIGO stage 1B1 cervical cancer is radical hysterectomy (RH) [1]. Indocyanine-green (ICG) is a drug injected within the cervical stroma to detect the sentinel lymph node (SLN) in cervical cancer [2,3]. ICG travels through the lymphatic channels in the lateral parametrium, which results enhanced with green, before reaching the SLNs. This could help identifying the surgical landmarks. The aim of this video is to propose a new approach to perform parametrial dissection as part of RH under the guidance of ICG...

The development and advancement of next generation sequencing have not only sped up the process of identifying rare variants, but have also enabled scientists to explore all variants in a single individual. The Pakistani population has a high ratio of first degree consanguinity, which is why it is a rich source for various kinds of genetic disorders. Due to the heterogeneous composition of Pakistani population, the likelihood of genetic heterogeneity for each disorder is high. Therefore, the compilation and organization of such vast genetic data is necessary to facilitate access for analysis and interpretation to researchers and medical geneticists...

Multiple collections of semen during the reproductive period of the common carp Cyprinus carpio L. were used to analyse changes in semen quality. Semen collection was performed on June 1 (first collection), 12 (second collection), and 19 (third collection) from individual males (n=11) by gentle abdominal massage. Semen quantity (semen volume and sperm count), quality (sperm motility and sperm viability), as well as seminal plasma parameters (pH of seminal plasma and seminal plasma osmotic pressure) and its enzymatic activity, e...

The brilliant cresyl blue (BCB) test is used in both basic biological research and assisted reproduction to identify oocytes likely to be developmentally competent. However, the underlying molecular mechanism targeted by the BCB test is still unclear. To explore this question, we first confirmed that BCB-positive porcine oocytes had higher rates of meiotic maturation, better rates of cleavage and development into blastocysts, and lower death rates. Subsequent single-cell transcriptome sequencing on porcine germinal vesicle (GV)-stage oocytes identified 155 genes that were significantly differentially expressed between BCB-negative and BCB-positive oocytes...

We present a case of prenatal diagnosis of a mediastinal cyst by ultrasound, confirmed during infancy through computed tomography (CT) and magnetic resonance imaging (MRI). A 6-month-old male infant was admitted to the hospital. A mid-mediastinal cyst was detected through a province-wide fetal ultrasonography screening program. During the infancy stage, the CT scan and the MRI confirmed the finding of a mediastinal cyst. Based on the findings on prenatal ultrasonography and postnatal imaging studies (CT, MRI), a benign mediastinal cyst was suspected...

We present here a 47-year old male patient who had a typical carcinoid tumor located at the orifice of right lower lobe bronchus underwent uniportal thoracoscopic lower lobectomy following bronchoscopic removal of the endobronchial tumor. Tumor was seen by bronchoscopy to protrude out from the lower lobe into the intermediary bronchus obstructing the lower lobe completely and the middle lob partially. However, the origin of the endobronchial tumor was in the distal part of the lower lobe bronchus. In this case, open surgery could be an alternative to save the middle lobe by incising the lower lobe bronchus to pull out the endobronchial tumor first during thoracotomy...

Diego Gonzalez-Rivas and his colleagues performed the first case for pulmonary major resection by the uniportal approach in 2010. In the following years, more and more expert surgeons developed the uniportal approach and even applied it to very complex cases. Many centers have showed that uniportal video-assisted thoracic surgery (VATS) lobectomy is a safe and feasible technique. The patient presented here is a complex case: The lingular segmental artery was invaded seriously by the tumor and it was difficult to divide it freely, and the pulmonary artery plasty was needed...

γ-Hydroxybutyric acid (GHB) is an endogenous compound with a historical use, both in licit and illicit terms. Importantly, the post-mortem behavior of GHB has been studied due to the possibility of using this compound as a biomarker for estimating the post-mortem interval (PMI). However, the post-mortem behavior of the recently discovered glucuronated GHB metabolite (GHB-GLUC) has not been studied. Nevertheless, GHB-GLUC may also have potential both to assist in PMI determination and also to increase the window of detection of GHB consumption...

Hydrogen gas production from solar water splitting provides a renewable energy cycle to address the grand global energy challenge, however, its dynamics and fundamental mechanism remain elusive. We directly explore by first principles the ultrafast electron-nuclear quantum dynamics on the timescale of ~100 femtoseconds during water photosplitting on plasmonic cluster embedded in liquid water. Water molecule splitting is assisted by rapid proton transport in liquid water in a Grotthuss-like mechanism. We identify that plasmon-induced field enhancement effect dominates water splitting, while charge transfer from gold to anti-bonding orbital of water molecule also plays an important role...

Sulfur-containing Anemarrhenae Rhizoma decoction pieces were prepared by using sulfur-fumigating procedure. The difference components before and after sulfur fumigation in Anemarrhenae Rhizoma were analyzed and on-line identified by UPLC-Q-TOF-MSE combined with UNIFI informatics platform, principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA) respectively. As a result, 16 major differences components were identified, and among them, 9 components were mainly from sulfur-fumigated samples...

BACKGROUND: Single-site laparoscopy is increasingly popular for straightforward operations like appendectomy. Due to limited triangulation and maneuverability, single-site cholecystectomy is riskier and more difficult. Robotics offer to make it easier and safer. METHODS: Twenty children and adolescents underwent robotic-assisted single-site cholecystectomy at a large academic children's hospital. Patients were not randomized; patients were offered the option of robotic-assisted single-site (SSR) or standard four-incision laparoscopic (LAP) cholecystectomy...

OBJECTIVES: Substantial development assistance and research funding are invested in health research capacity strengthening (HRCS) interventions in low-income and middle-income countries, yet the effectiveness, impact and value for money of these investments are not well understood. A major constraint to evidence-informed HRCS intervention has been the disparate nature of the research effort to date. This review aims to map and critically analyse the existing HRCS effort to better understand the level, type, cohesion and conceptual sophistication of the current evidence base...
