BACKGROUND: Limited attention has been given to the effects of classroom acoustics at the college level. Many studies have reported that nonnative speakers of English are more likely to be affected by poor room acoustics than native speakers. An important question is how classroom acoustics affect speech perception of nonnative college students. PURPOSE: The combined effect of noise and reverberation on the speech recognition performance of college students who differ in age of English acquisition was evaluated under conditions simulating classrooms with reverberation times (RTs) close to ANSI recommended RTs...

Redox-responsive linkages dispersed in the backbones of the synthetic polymers, while young in the current spectrum of the biomedical application, are rapidly extending into their niche. In the present work, triblock copolymer PEG-PLA-PEG synthesized and characterized by (1)H -NMR and SEC can self-assemble into redox-responsive micelles in aqueous media with nanosized 33nm and 47nm. And the copolymers PEG2000-PLA3000-PEG2000 and PEG2000-PLA5000-PEG2000 present lower CMC with 0.034 and 0.022mg/mL, and higher DLC of 4...

The aim of this study was to assess the function of the utricle and horizontal semicircular canals in patients with type 2 diabetes mellitus receiving primary health care, with/without a history of falls. 101 patients with type 2 diabetes mellitus, 34 to 84 years old (26 with and 75 without a history of falls) and 51 healthy volunteers (40-83 years old) accepted to participate. They denied having a history of dizziness, vertigo, unsteadiness, hearing loss or neurological disorders. None of them were seeking care due to sensory or balance decline...

INTRODUCTION: Dysphonia significantly damages quality of life and employment opportunities. One of the common causes of hoarseness is glottic insufficiency, namely the lack of full adherence of the vocal cords during speech and swallowing. Correction is achieved by vocal cord medialization. OBJECTIVES: To examine the effect of vocal cord injection with carboxymethyl cellulose and hydroxyapatite under local anesthesia in the office, on the voice objectively, assessment by staff and patient satisfaction...

Hepatectomy needing simultaneous reconstruction of the hepatic artery and the portal vein in the operation for cholangiocarcinoma is a challenging procedure. We experienced three cases of left hepatectomy with simultaneous reconstructions of the right hepatic artery (RHA) and the right portal vein (RPV) in all of which the surgical procedures were performed in the same manner. At the initial step of the procedure, we confirmed that the RHA and the RPV at the porta hepatis as well as the proper hepatic artery and the main portal vein (MPV) proximal to the cancer involvement could be controlled by tapes, which meant the cancer could be resected by means of vascular reconstructions...

The title hydrated mol-ecular salt, C4H12N(+)·C4H5O6(-)·H2O, was prepared by deprotonation of enanti-opure l-tartaric acid with racemic sec-butyl-amine in water. Only one enanti-omer was observed crystallographically, resulting from the combination of (S)-sec-butyl-amine with l-tartaric acid. The sec-butyl-ammonium moiety is disordered over two conformations related by rotation around the CH-CH2 bond; the refined occupancy ratio is 0.68 (1):0.32 (1). In the crystal, mol-ecules are linked through a network of O-H⋯O and N-H⋯O hydrogen-bonding inter-actions, between the ammonium H atoms, the tartrate hy-droxy H atoms, and the inter-stitial water, forming a three-dimensional supra-molecular structure...

Appropriate characterization of soluble aggregates is an important aspect of biologics development and manufacturing, and sedimentation velocity analytical ultracentrifugation (SV-AUC) is often used an orthogonal technique to size-exclusion chromatography (SEC) for this purpose. Precise quantification of low levels of soluble aggregates by SV-AUC can be adversely impacted by improper cell alignment. This report describes the development of an optical system capable of quantifying cell alignment that affords a substantial improvement compared to historical approaches...

The crystallizable fragment (Fc) of the immunoglobulin class G (IgG) is an attractive scaffold for the design of novel therapeutics. Upon engineering the C-terminal loops in the CH3 domains, Fcabs (Fc domain with antigen-binding sites) can be designed. We present the first crystal structures of Fcabs, i.e., of the HER2-binding clone H10-03-6 having the AB and EF loop engineered and the stabilized version STAB19 derived by directed evolution. Comparison with the crystal structure of the Fc wild-type protein reveals conservation of the overall domain structures but significant differences in EF-loop conformations...

A non-invasive, auricular percutaneous electrical nerve field stimulation (PENFS) has been suggested to modulate central pain pathways. We investigated the effects of BRIDGE® device on the responses of amygdala and lumbar spinal neurons and the development of post-colitis hyperalgesia. Male Sprague-Dawley rats received intracolonic trinitrobenzene sulfonic acid (TNBS) and PENFS on the same day. Control rats had sham devices. The visceromotor response (VMR) to colon distension and paw withdrawal threshold (PWT) was recorded after 7 days...

BACKGROUND: Cyclodextrin glucanotransferases (CGTases) catalyze the synthesis of cyclodextrins, cyclic oligosaccharides composed of glucose monomers that find applications in the pharmaceutical, food, and cosmetic industries. An economic application of these industrially important enzymes requires their efficient production and recovery. In this study, the effect of Sec-type signal peptides on the recombinant expression of a CGTase derived from Bacillus sp. G825-6 was investigated in Escherichia coli BL21(DE3) using a codon-adapted gene...

A total of 120 samples including 40 freshwaterfish(Oncorhynchus mykiss), 40 seawater fish (Sparus aurata) and 40 ground beef samples were examined for the presence of Staphylococcus aureus. The isolates were identified using biochemical tests and a PCR for the species-specific fragment (Sa442) and thermonuclease gene (nucA). The presence of staphylococcal enterotoxin genes (sea, seb, sec, sed and see), toxin genes (eta, etb, tsst), methicillin resistance gene (mecA) and some phenotypic virulence factors was also tested...

Coating fertilizer particles with thin films is a possibility to control the fertilizer release rates. It is observed that novel urea crosslinked starch-lignin composite thin films, prepared by solution casting, swell on coming into contact with water due to increase in volume by water uptake diffusion. The effect of lignin content, varied from 0% to 20% in steps of 5% and three different temperatures (25°C, 35°C and 45°C) on swelling of the film was investigated. By gravimetric analysis, the equilibrium water uptake and diffusion coefficient decrease with lignin content indicating that the addition of lignin increases the hydrophobicity of the films...

RATIONALE: Mecasermin is used to treat elevated blood sugar as well as growth hormone-resistant Laron-type dwarfism. Mecasermin isolated from inclusion bodies in extracts of E.coli must be refolded to acquire sufficient activity. However, there is no rapid analytical method for monitoring refolding during the purification process. METHODS: We prepared mecasermin drug product, in-process samples during the oxidation of mecasermin, forced-reduced mecasermin, and aerially oxidized mecasermin after forced reduction...

Polysaccharide TEMPO-oxidation was monitored using automatic continuous online monitoring of polymerization reactions (ACOMP). The products of oxidation, obtained at different pHs (9, 7 and 5) and different concentrations of catalyst TEMPO, were evaluated by Automatic Continuous Mixing (ACM) and Size Exclusion Chromatography (SEC). The degree of oxidation was higher at pH 9 and polysaccharide degradation was observed under different pH conditions, but was much higher without catalyst TEMPO. The rate constant (k) was dependent on reaction pH and TEMPO concentration...

Assessment of hepatic functional reserve is important to enable the selection of appropriate treatment methods and safe hepatic resection in hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC). In the present study, an evaluation was made of the clinical value of combining the Child-Pugh score (CPS) with the standardized future liver remnant (sFLR) measurement to predict postoperative liver dysfunction (PLD). A total of 61 HBV-related HCC patients undergoing liver volumetry prior to hepatectomy were enrolled in the study...
