The use of supplements, such as porcine follicular fluid (pFF), fetal bovine serum and human serum albumin are widely used during in vitro maturation (IVM) in different species but these supplements contain undefined components that cause technical difficulties in standardization and influence the efficiency of IVM. Knockout serum replacement (KSR) is a synthetic protein source, without any undefined growth factors or differentiation-promoting factors. Therefore, it is feasible to use KSR as a defined component for avoiding effects of unknown molecules in an IVM system...

The present work demonstrates an extremely proficient and robust study of efficient interfacial charge transfer through plasmonic Ag decorated Bi2O3 hierarchical photoanodes for the photoelectrochemical treatment of chlorinated phenols. Unique 2D flake-like Bi2O3 hierarchical nanostructures were grown onto a fluorine-doped tin oxide (FTO) substrate by a simple chemical bath deposition method using triethanolamine as complexing agent. The formation of Bi2O3 on FTO was governed by the decomposition of a nucleated bismuth-hydroxyl complex (Bi2O1-x(OH)x) and modification to the electrode was carried out by the deposition of Ag via a chemical reduction method using hydrazine hydrate...

This study developed a high-strength molded fiber material (HMFM) using pulp fibers, which could be a good substitute for plastic and solid wood materials. The surface composition, microstructure and thermal properties of HMFM were investigated by XPS, SEM and DSC, respectively. The SEM observations showed that the obvious adhesive substances and agglomeration appeared among fibers, and the inter-fiber contact area and binding tightness increased after the light-delignification. The XPS examination showed that the oxygen-rich composition on the outer surface of HMFM were reduced, and the outer surface coverage of lignin increased from 70...

Hydrogen sulfide (H2S) plays important roles in the pathogenesis of periodontitis. Oral pathogens typically produce H2S from L-cysteine in addition to pyruvate and NH4+ However, fn1055 from Fusobacterium nucleatum subsp. nucleatum ATCC 25586 encodes a pyridoxal 5'-phosphate (PLP)-dependent enzyme that catalyzes the production of H2S and L-serine from L-cysteine and H2O, an unusual cysteine (hydroxyl) lyase reaction (β-replacement reaction). To reveal the reaction mechanism, the crystal structure of substrate-free Fn1055 was determined...

The strategy of applying fluorine NMR to characterize ligand binding to a membrane protein prepared with mixtures of tryptophans substituted with F at different positions on the indole ring was tested. The ¹⁹F NMR behavior of 4-, 5-, 6-, and 7-fluorotryptophan were directly compared as a function of both micellar environment and fragment size for two overlapping apelin receptor (AR/APJ) segments - one with a single transmembrane (TM) helix and two tryptophan residues, the other with three TM helices and two additional tryptophan residues...

BACKGROUND: Papaverine remains a popular agent to treat intraoperative microsurgical vasospasm. However, the recent shortage has forced surgeons to trial antispasmodic agents unproven in microsurgery, but commonly used in other areas. During this shortage we have trialed topical nitroglycerin to break intraoperative vasospasm. This study aims to analyze the outcomes of this medication on flap complications compared with papaverine. METHODS: All consecutive free flaps performed for breast reconstruction at a single institution were reviewed...

The native chemical ligation (NCL) is an invaluable tool in the total chemical synthesis of proteins. Ligation auxiliaries overcome the requirement for cysteine. However, the reported auxiliaries remained limited to glycine-containing ligation sites and the acidic conditions applied for cleavage of the typically applied N-benzyl-type linkages promote side reactions. With the aim to improve upon both ligation and cleavage, we systematically investigated alternative ligation scaffolds that challenge the N-benzyl dogma...

Background: The presence of different missense mutations in sheep breeds have shown that the bone morphogenetic protein receptor 1B (BMPR1B), bone morphogenetic protein 15 (BMP15) and growth differentiation factor 9 (GDF9) genes play a vital role in ovulation rate and prolificacy in ewes. Therefore, the present study aims to investigate BMPR1B, BMP15 and GDF9 gene mutations in prolific ewes of Iranian fat-tailed Lori-Bakhtiari sheep. MATERIALS AND METHODS: In the present experimental study, genomic DNA was extracted from whole blood of 10 prolific Lori-Bakhtiari ewes with at least two twinning records in the first four parities to identify point mutations of the BMPR1B, BMP15 and GDF9 genes, using DNA sequencing...

It is well-documented that feedforward cardiovascular responses occur at the onset of exercise, but it is unclear if such responses are associated with other types of movements. In this study, we tested the hypothesis that feedforward cardiovascular responses occur when a passive (imposed) 60° head-up tilt is anticipated, such that changes in heart rate and carotid artery blood flow (CBF) commence prior to the onset of the rotation. A light cue preceded head-up tilts by 10 sec, and heart rate and CBF were determined for 5-sec time periods prior to and during tilts...

Bioorthogonal prodrug activation/decaging strategies need to be selective, rapid and release the drug from the masking group upon activation. The rates of the 1,3-dipolar cycloaddition between a trans-cyclooctene (TCO) and a series of fluorine-substituted azido-PABC self-immolative spacers caging two model drugs, and subsequent release from the 1,2,3-triazoline are reported. As the number of fluorine substituents on the PABC linker increases from one to four, the rate of cycloaddition increases by almost one-order of magnitude...

Many viroids and RNA viruses have genomes that exhibit secondary structure, with paired nucleotides forming stems and loops. Such structures violate a key assumption of most methods of phylogenetic reconstruction, that sequence change is independent among sites. However, phylogenetic analyses of these transmissible agents rarely use evolutionary models that account for RNA secondary structure. Here we assess the effect of using RNA-specific nucleotide substitution models on the phylogenetic inference of viroids and RNA viruses...

Due to the high prevalence of incontinence among skilled nursing facility (SNF) residents, incontinence-associated derma- titis (IAD) is a common occurrence. In addition, facility staff may mistakenly identify IAD as a pressure injury. A prospective, descriptive, multicenter study was conducted in 3 Connecticut facilities to evaluate the effect of substituting a disposable, high- uid capacity underpad for nonpermeable disposable and reusable containment products on the rate of IADs. Residents with and without IAD but with high IAD risk scores who were bed- or chairbound or ambulatory and used disposable nonpermeable briefs and underpads or reusable, laundered containment products when in bed longer than 2 hours were randomly enrolled and observed for a 4-week period...
