Atomic Layer Deposition of TiO on Si Window Enables ATR-SEIRAS Measurements in Strong Alkaline Electrolytes.

The Si window is the most widely used internal reflection element (IRE) for electrochemical attenuated total reflection surface-enhanced infrared absorption spectroscopy (ATR-SEIRAS), yet local chemical etching on Si by concentrated OH anions bottlenecks the reliable application of this method in strong alkaline electrolytes. In this report, atomic layer deposition of a 25 nm nonconductive TiO barrier layer on the reflecting plane of a Si prism is demonstrated to address this challenge. ATR-SEIRAS measurement on a Au film electrode with the Si/TiO composite IRE in 1 M NaOH reveals reversible global spectral features without spectral distortion at 1000-1300 cm, in stark contrast to those obtained with a bare Si window.

Virtual sketching-based dental anatomy module improves learners' abilities to use computer-aided design to create dental restorations and prostheses.

A 1.1 Mb duplication CNV on chromosome 17 contributes to skeletal muscle development in Boer goats.

The Boer goat is one of the top meat breeds in modern animal husbandry and has attracted widespread attention for its unique growth performance. However, the genetic basis of muscle development in the Boer goat remains obscure. In this study, we identified specific structural variants in the Boer goat based on genome-wide selection signals and analyzed the basis of the molecular heredity of related candidate genes in muscle development.

A Catechol-Meter Based on Conventional Personal Glucose Meter for Portable Detection of Tyrosinase and Sodium Benzoate.

In this study, the personal glucose meter (PGM) was first used as a fast and user-friendly meter for analyzing catechol (CA) based on the reduction of the mediator K[Fe(CN)] to K[Fe(CN)] in the glucose test strip. Then, an easy, low-cost, and convenient PGM-based method for detecting tyrosinase (TYR) activity and sodium benzoate (SBA) was developed on the basis of the TYR-catalyzed reaction. In this method, CA is oxidized to form -benzoquinone by TYR, thereby reducing the residual amount of CA and the PGM readout.

A Paper-Based Analytical Device Integrated with Smartphone: Fluorescent and Colorimetric Dual-Mode Detection of β-Glucosidase Activity.

In this work, indoxyl-glucoside was used as the substrate to develop a cost-effective, paper-based analytical device for the fluorescent and colorimetric dual-mode detection of β-glucosidase activity through a smartphone. The β-glucosidase can hydrolyze the colorless substrate indoxyl-glucoside to release indoxyl, which will be self-oxidized to generate green products in the presence of oxygen. Meanwhile, the green products emit bright blue-green fluorescence under ultraviolet-visible light irradiation at 365 nm.

Multicolor colorimetric assay for copper ion detection based on the etching of gold nanorods.

An effective, selective, and multicolor colorimetric assay for Cu detection based on the regulation of peroxidase-like nanozyme-mediated etching of gold nanorods (Au NRs) is proposed. Cu-creatinine complex is selected as the nanozyme that exhibits excellent peroxidase-like activity even in the case of low concentration of Cu, which can catalyze 3,3,5,5-tetramethylbenzidine (TMB) to produce oxidized TMB (TMB) in the presence of hydrogen peroxide, and TMB is oxidized to generate TMB after adding H, and the TMB can etch Au NRs. The determination of Cu is achieved based on the blue shift of the longitudinal localized surface plasmon resonance peak of Au NRs.

Aspiration as the first-choice procedure for airway management in an infant with large epiglottic cysts: A case report.

Background: Epiglottic cysts is a rare but potentially lethal supraglottic airway pathology in infants due to the high risk of cannot intubation or cannot ventilation. Awake fiberoptic intubation appeared to be the safest technique, but it is very challenging in infants with large epiglottic cysts. Even it has the risk of airway loss.

Myocarditis complicated by massive right ventricular thrombus and extensive pulmonary embolism: A case report.

An intracardiac thrombus may develop as a consequence of myocarditis, and in rare cases, a dominantly right ventricular thrombus develops, which may impair cardiac function and even cause life-threatening cardiovascular events. We report a 24-year-old man presented with recurrent episodes of palpitation and precordial discomfort after catching a cold 2 months ago. Transthoracic echocardiography (TTE) and computed tomography pulmonary angiogram (CTPA) revealed a mass attached to the apex of the right ventricle and extensive bilateral pulmonary artery emboli.

Electrolyte-Layer-Tunable ATR-SEIRAS for Simultaneous Detection of Adsorbed and Dissolved Species in Electrochemistry.

A balanced detection of both adsorbates and dissolved species is very important for the clarification of the electrochemical reaction mechanism yet remains a major challenge for different modes of electrochemical infrared (IR) spectroscopy. Among others, conventional attenuated total reflection-surface-enhanced IR absorption spectroscopy (ATR-SEIRAS) is far less sensitive to low-concentration solution species than to surface species. We report herein an electrochemical wide-frequency ATR-SEIRAS with a novel thin-layer flow cell design, fulfilling the simultaneous detection of the variations of surface and solution species.

Geographical contrasts of Y-chromosomal haplogroups from wild and domestic goats reveal ancient migrations and recent introgressions.

By their paternal transmission, Y-chromosomal haplotypes are sensitive markers of population history and male-mediated introgression. Previous studies identified biallelic single-nucleotide variants in the SRY, ZFY and DDX3Y genes, which in domestic goats identified four major Y-chromosomal haplotypes, Y1A, Y1B, Y2A and Y2B, with a marked geographical partitioning. Here, we extracted goat Y-chromosomal variants from whole-genome sequences of 386 domestic goats (75 breeds) and seven wild goat species, which were generated by the VarGoats goat genome project.

Monocytic MDSC mobilization promotes tumor recurrence after liver transplantation via CXCL10/TLR4/MMP14 signaling.

Tumor recurrence is the major obstacle for pushing the envelope of liver transplantation for hepatocellular carcinoma (HCC) patients. The inflammatory cascades activated by acute liver graft injury promote tumor recurrence. We aimed to explore the role and mechanism of myeloid-derived suppressor cell (MDSC) mobilization induced by liver graft injury on tumor recurrence.

Successful experience in dealing with tooth aspiration after extubation: a case report.

There is a high incidence of tooth injury or loss due to endotracheal intubation or extubation. Tooth injury may be costly or even life threatening. In particular, tooth aspiration may cause airway obstruction, aspiration pneumonitis, or lung collapse, but tooth aspiration after tracheal extubation is rarely reported and easily overlooked.
