In this study, we applied a second round of random mutagenesis using ethyl methanesulfonate to further increase the lipid productivity of a Chlorella vulgaris mutant strain. We generated a mutant (UV715-EMS25) with a lipid content and biomass that were respectively 67% and 35% higher than those of the wild type (WT). The highest achieved lipid productivity in UV715-EMS25 was 91 mg L-1 day-1. Gas chromatography-mass spectrophotometric analysis revealed that the fatty acid methyl ester content of the mutant was 3...

The literature is reviewed regarding of a rare molecularly defined group of sarcomas with rearrangement of both CIC and BCOR genes, which were originally placed into the EWSR1wt Ewing-like category. Personal experience with three cases demonstrating difficulties of this issue is added. Both groups of lesions differ not only by age and topography, but also vary in both the prognostic and the predictive parameters. CIC-rearranged tumors are very aggressive and almost never occur in the skeleton; in contrary, the BCOR-rearranged ones are predominantly bone tumors in young males behaving even better than classical Ewing sarcoma...

Central nervous system high-grade neuroepithelial tumors with BCOR alteration (CNS HGNET-BCOR) are a recently reported rare entity, identified as a small fraction of tumors previously institutionally diagnosed as so-called CNS primitive neuroectodermal tumors. Their genetic characteristic is a somatic internal tandem duplication in the 3' end of BCOR (BCOR ITD), which has also been found in clear cell sarcomas of the kidney (CCSK) and soft tissue undifferentiated round cell sarcomas/primitive myxoid mesenchymal tumors of infancy (URCS/PMMTI), and these BCOR ITD-positive tumors have been reported to share similar pathological features...

An 82-year-old woman was diagnosed with cholecystitis with a right-sided round ligament. We planned a single-incision laparoscopic cholecystectomy. Based on the findings of fluorescent cholangiography, the running course of the common bile duct was confirmed before dissection of Calot's triangle, and the confluence between the cystic duct and the common bile duct was exposed after the dissection of Calot's triangle. The planned surgery was successful. The operative time and intraoperative blood loss were 157 min and 2 mL, respectively...

The emergence of van der Waals (vdW) heterostructures of 2D materials has opened new avenues for fundamental scientific research and technological applications. However, the current concepts and strategies of material engineering lack feasibilities to comprehensively regulate the as-obtained extrinsic physicochemical characters together with intrinsic properties and activities for optimal performances. A 3D mesoporous vdW heterostructure of graphene and nitrogen-doped MoS2 via a two-step sequential chemical vapor deposition method is constructed...

Background: Colorectal cancer (CRC) screening is the most efficient strategy to reduce disease-related mortality. Frequent aberrant DNA methylation is known to occur in selected genes and early during CRC development, which has emerged as a new epigenetic biomarker for early detection of CRC. Previously, we reported that we identified that CpG sites of SDC2 were aberrantly methylated in tumor tissues of most CRC patients through comprehensive methylation analysis and demonstrated a high potential of quantification of SDC2 methylation in blood for early detection of colorectal cancer...

Unacylated ghrelin, the predominant form of circulating ghrelin, protects myotubes from cell death, which is a known attribute of pressure ulcers. In this study, we investigated whether unacylated ghrelin protects skeletal muscle from pressure-induced deep tissue injury by abolishing necroptosis and apoptosis signaling and whether these effects were mediated by SIRT1 pathway. Fifteen adult Sprague Dawley rats were assigned to receive saline or unacylated ghrelin with or without EX527 (a SIRT1 inhibitor). Animals underwent two 6-h compression cycles with 100 mmHg static pressure applied over the mid-tibialis region of the right limb whereas the left uncompressed limb served as the intra-animal control...

Desmoplastic small round blue cell tumors (DSRCTs) originate from a cell with multilineage potential. A molecular hallmark of DSRCT is the EWS-WT1 reciprocal translocation. Ewing sarcoma and DSRCT are treated similarly due to similar oncogene activation pathways, and DSRCT has been represented in very limited numbers in sarcoma studies. Despite aggressive therapy, median survival ranges from 17 to 25 months, and 5-year survival rates remain around 15%, with higher survival reported among those undergoing removal of at least 90% of tumor in the absence of extraperitoneal metastasis...

PURPOSE: Lack of human resources is a major barrier to accessing pediatric surgical care globally. Our aim was to establish a model for pediatric surgical training of general surgery residents in a resource constrained region. MATERIALS/METHODS: A pediatric surgical program with a pediatric surgical rotation for general surgery residents in a tertiary hospital in Haiti in 2015 was established. We conducted twice daily patient rounds, ran an outpatient clinic, and provided emergent and elective pediatric surgical care, with tasks progressively given to residents until they could run clinic and perform the most common elective and emergent procedures...

Directed evolution has proven to be an invaluable tool for protein engineering; however, there is still a need for developing new approaches to continue to improve the efficiency and efficacy of these methods. Here, we demonstrate a new method for library design that applies a previously developed bioinformatic method, Statistical Coupling Analysis (SCA). SCA uses homologous enzymes to identify amino acid positions that are mutable, functionally important, and engage in synergistic interactions between amino acids...

The auditory system is thought to process complex sounds through overlapping bandpass filters. Frequency selectivity as estimated by auditory filters has been well quantified in humans and other mammalian species using behavioral and physiological methodologies, but little work has been done to examine frequency selectivity in nonhuman primates. In particular, knowledge of macaque frequency selectivity would help address the recent controversy over the sharpness of cochlear tuning in humans relative to other animal species...

Fuming Sang, Xin Li, Zhizhou Zhang, Jia Liu, Guofu Chen
In this work, a rapid, simple and sensitive colorimetric sensor for simultaneous (or respective) detection of Cr3+ and Pb2+ using tyrosine functionalized gold nanoparticles (AuNPsTyr) has been developed. Tyrosine, a natural and zwitterionic amino acid, could be as a reducing and capping agent to synthesise AuNPs and allow for the simultaneous and selective detection of Cr3+ and Pb2+. Upon the addition of Cr3+ or Pb2+ (a combination of them), the color of AuNPsTyr solution changes from red to blue grey and the characteristic surface plasmon resonance (SPR) band is red-shifted to 580nm due to the aggregation of AuNPs...

Importance: The nasal base view is often overlooked in rhinoplasty analysis and, unlike lateral and frontal views, lacks detailed quantitative analysis and descriptors. While shape-category analysis of the nasal base is well established, these descriptive methods remain subjective and do not facilitate quantitative analysis. Objective: To establish a simple and quantitative classification scheme using a multiple-parameter numerical model for analyzing and describing the shape of the nasal base...

The role of basal suppression of Sonic hedgehog (Shh) pathway and its interaction with Indian hedgehog (Ihh) signaling during limb/skeletal morphogenesis is not well understood. The orphan G-protein-coupled receptor, Gpr161 localizes to primary cilia, and functions as a negative regulator of Shh signaling by promoting Gli transcriptional repressor versus activator formation. Here, we show that forelimb buds are not formed in Gpr161 knockout mice embryos despite establishment of prospective limb fields. Limb-specific deletion of Gpr161 resulted in prematurely expanded Shh signaling and ectopic Shh-dependent patterning defects to cause polysyndactyly...
