Globally, approximately 1 in 15 men of reproductive age are infertile, yet the precise mechanisms underlying their gamete failure are unknown. Although a semen-analysis is performed to determine fertilizing potential, the diagnostic suitability of this analysis has been questioned in several reports, as many men, classified as "infertile" according to their semen analysis, subsequently turn out to be fertile. Herein, we have used a quantitative (phospho)-proteomic analysis, using enrichment on titanium dioxide followed by ion-trap mass spectrometry (LC-MS/MS), to compare the semen of infertile versus fertile males...

Random conical tilt (RCT) and orthogonal tilt reconstruction (OTR) are two remarkable methods for reconstructing the three-dimensional structure of macromolecules at low resolution. These techniques use two images at two different sample tilts. One of the most demanding steps in these methods at the image processing level is to identify corresponding particles on both micrographs, and manual or semiautomatic matching methods are usually used. Here we present an approach to solve this bottleneck with a fully automatic method for assigning particle tilt pairs...

BACKGROUND: To humanize yeast N-glycosylation pathways, genes involved in yeast specific hyper-mannosylation must be disrupted followed by the introduction of genes catalyzing the synthesis, transport, and addition of human sugars. However, deletion of these genes, for instance, OCH1, which initiates hyper-mannosylation, could cause severe defects in cell growth, morphogenesis and response to environmental challenges. RESULTS: In this study, overexpression of RHO1, which encodes the Rho1p small GTPase, is confirmed to partially recover the growth defect of Saccharomyces cerevisiae Δalg3Δoch1 double mutant strain...

Importance: Cutaneous surgery is performed by otolaryngologists, plastic surgeons, oculoplastic surgeons, dermatologic surgeons, and some primary care physicians. Practice gaps exist among cutaneous surgeons, as do differences in how different physicians approach preoperative, intraoperative, and postoperative decision-making. Objective: To present the newest and best evidence to close common practice gaps in cutaneous surgery. Evidence Review: We performed a detailed search of peer-reviewed publications that were identified through a search of PubMed/MEDLINE (January 1, 2000, through June 30, 2016) using the literature search terms "cutaneous surgery," "Mohs micrographic surgery," "plastic surgery," in combination with "safety," "cost," "anesthesia," "anti-coagulation," "bleeding," "pain," "analgesia," "anxiety," or "infection," among others...

This article presents the complementary data regarding compatibilization of chitosan/κ-carrageenan polyelectrolyte complex for synthesizing of a soft film using ascorbic acid. It includes the thermal-theory for estimating the degradation of κ-carrageenan, as reflected in alteration of the structural properties of the blend. The data has been provided to demonstrate that the blend solution based on chitosan, a polycation, and κ-carrageenan, a polyanion polymer, produces an incompatible polyelectrolyte composite, susceptible to coaservative phase separation...

BACKGROUND: Basal cell carcinoma (BCC) is the most common malignancy in the United States. Most BCCs occur on cutaneous surfaces, but rare cases on the mucosal lip have also been documented. Because only a small number of mucosal BCC (mBCC) cases have been reported, data on their clinical characteristics and management are limited. OBJECTIVE: To perform an updated literature review of the management of mBCCs on the lip. METHODS: A comprehensive literature review was conducted through a search of the PubMed database with the key phrases "mucosal basal cell carcinoma," "basal cell carcinoma mucosa," and "basal cell carcinoma lip mucosa...

Pleomorphic dermal sarcoma (PDS) is a rare mesenchymal neoplasm sharing histopathological features with atypical fibroxanthoma (AFX), but has additional features of deep invasion of the superficial subcutis, tumor necrosis and vascular/perineural invasion. It is not well documented in the literature because of its rarity, and its clinical course has been debated due to the lack of homogenous criteria. We describe here the case of a 91-year-old female with a 6-month history of a solitary, asymptomatic, well-defined, 3...

BACKGROUND: The patient and observer scar assessment scale (POSAS) recently emerged as a promising method, reflecting both observer's and patient's opinions in evaluating scar. This tool was shown to be consistent and reliable in burn scar assessment, but it has not been tested in the setting of skin graft scar in skin cancer patients. OBJECTIVE: To evaluate facial skin graft scar applied to POSAS and to compare with objective scar assessment tools. METHODS: Twenty three patients, who diagnosed with facial cutaneous malignancy and transplanted skin after Mohs micrographic surgery, were recruited...

Dermatologists frequently create cutaneous defects that heal by second intention, yet there is no universal protocol for wound care in this setting. Several ointments commonly used for wound healing are not cost effective as they contain known contact allergens, contribute to antimicrobial resistance, and do not enhance the healing process. Recent studies indicate that Bensal HP, a commercially available ointment used for a variety of dermatologic conditions, may be useful for wound healing; although clinical data is currently limited...

Red light emitting cubic Zr0.99Eu0.01O2:Li(+) (0-9 mol%) nanoparticles are synthesized by a low temperature, self-propagating solution combustion method using oxalyl di-hydrazide (ODH) as fuel. In this study, we report systematic investigation of the effect of lithium ion (Li(+)) concentration on the structural properties and the photoluminescence of zirconia. With increasing lithium concentration, the crystallinity of the samples increases and the lattice strain decreases. The higher crystallinity is likely due to charge compensation achieved by replacing one Zr(4+) ion by a Eu(3+) and a Li(+) ion...

Basal cell carcinoma (BCC) typically occurs in sun-exposed sites. Only 16 individuals with umbilical BCC have been described in the literature, and the characteristics of patients with umbilical BCC are summarized. PubMed was used to search the following terms: abdomen, basal cell carcinoma, basal cell nevus syndrome, and umbilicus. Papers with these terms and references cited within these papers were reviewed. BCC of the umbilicus has been reported in five men and 11 women; one man had two tumors. Two patients had basal cell nevus syndrome (BCNS)...

The concept that the B-cell Receptor (BCR) initiates a driver pathway in lymphoma-leukemia has been clinically validated. Previously described unique BCR Ig-class-specific sequences (proximal domains (PDs)), are not expressed in serum Ig (sIg). As a consequence of sequence and structural differences in the membrane IgM (mIgM) µ-Constant Domain 4, additional epitopes distinguish mIgM from sIgM. mAbs generated to linear and conformational epitopes, restricted to mIgM and not reacting with sIgM, were generated despite the relative hydrophobicity of the PDm sequence...

Sugarcane bagasse (B), a low cost agricultural waste, was modified via esterification and coating with polyacrylonitrile (PAN) and evaluated as a hydrophobic sorbent for diesel oil removal from artificial seawater. Esterification was carried out using stearic acid (SA) and CaO, the reaction conditions including B:SA mass ratio, CaO concentration, reaction time and temperature were optimized. Additional hydrophobicity was achieved by coating the esterified bagasse (EB) with a hydrophobic polymer (PAN). The advantages of hydrophobicity were clearly addressed by reduction of water absorption capacity (WAC) and increased oil adsorption capacity (OAC)...

Collagen, one of the most biocompatible materials in nature, is widely used in wound healing and organ repair. However, the limited mechanical strength and biological effectiveness of collagen restrain its application as a hemostasis and filling material in medicine. To overcome these limitations, ultraporous collagen/oxidized regenerated cellulose (Col/ORC) composites were prepared. The results showed that the Col-0.25%ORC composite had optimal wettability, porosity, and water absorption. An MTT assay proved that the Col and Col/ORC composites possessed no cytotoxicity in living cells...
