Health systems responsiveness towards needs of pregnant women in Vietnam.

Background: Health systems that are responsive to maternal mental health recognise the importance of integrating mental health services into maternal care. Studies from Vietnam have reported particularly high rates of common perinatal mental health disorders (CPMDs) in both rural and urban areas of the country. Despite the increasing burden of maternal mental health conditions, there is currently no guidance on the screening for CPMDs within maternal care, both antenatal and postnatal.

HPTLC sequentially coupled to UV and SERS: A cost-effective tool for confirmative identification and quantitation of sildenafil in falsified herbal products.

The detection of falsified drugs usually requires multi-disciplinary analysis for confirmative identification. Among hyphenated techniques with high specificity detection, thin-layer chromatography coupled with surface-enhanced Raman spectroscopy (TLC-SERS) is an efficient choice, especially for herbal products with diversified matrix. In this study, HPTLC was coupled to two detection techniques: UV absorption and Raman scattering with silver colloid enhancement for the analysis of sildenafil adulterated in herbal products.

Visible-light-driven photodegradation of methylene blue and doxycycline hydrochloride by waste-based S-scheme heterojunction photocatalyst BiOI/PCN/tea waste biochar.

Herein, we have reported a photocatalytic BiOI, protonated g-CN heterojunction with directional charge transfer channels provided by tea waste biochar to achieve effective e/h pair isolation for the improved degradation of Methylene blue (MB) and Doxycycline hydrochloride (DCHCl). An S-scheme heterojunction was fabricated via the novel method that combined hydrothermal and ultrasonic dispersion, followed by an electrostatic self-assembly route. The as-fabricated BiOI/protonated g-CN/Tea waste biochar heterojunction formed a strong contact at the interface, as supported by the electron microscopic results.

Single versus Double Coffee-Ring Effect Patterns in Thin-Layer Chromatography Coupled with Surface-Enhanced Raman Spectroscopic Analysis of Anti-Diabetic Drugs Adulterated in Herbal Products.

In thin-layer chromatography coupled with surface-enhanced Raman spectroscopy (TLC-SERS), the coffee ring effect (CRE) describes the formation of a ring-shape spot (blank in the middle and darker on the edge) caused by the aggregation of silver nanoparticles (Ag NPs), alone (single CRE) or with the analytes (double CRE). In this work, the SCRE and DCRE were investigated in two anti-diabetic drugs, hydrophobic glibenclamide (GLB) and more hydrophilic metformin (MET). The SCRE occurred in GLB analysis, as opposed to the DCRE that occurred in MET.

Antimicrobial Activity and Sorption Behavior of AlO/Ag Nanocomposites Produced with the Water Oxidation of Bimetallic Al/Ag Nanoparticles.

The water oxidation of bimetallic Al/Ag nanoparticles has been shown to yield nanoscale structures whose morphology, phase composition and textural characteristics are determined by the synthesis conditions. Flower-like nanoscale structures with silver nanoparticles, with an average size of 17 nm, are formed in water at 60 °C. Under hydrothermal conditions at temperatures of 200 °C and a pressure of 16 MPa, boehmite nanoplatelets with silver nanoparticles, with an average size of 22 nm, are formed.

Isolation and genetic characterization of canine distemper virus in domestic dogs from central and northern provinces in Vietnam.

Canine distemper virus (CDV) is a pathogen causing fatal disease in a wide range of carnivores. Sequence analysis of CDV strains has been classified into several geographically-related lineages, and the evolution and emergence of these strains are not fully yet investigated. In this study, the complete H gene sequences of 15 CDV strains isolated on Vero DST cell culture from clinical samples of vaccinated domestic dogs in Vietnam were investigated.

In this study, a UV-curable acrylate epoxy nanocomposite coating has been prepared by incorporation of ZnO-Ag hybrid nanoparticles. For this purpose, firstly ZnO-Ag hybrid nanoparticles were fabricated by a seed-mediated growth method. Then, these ZnO-Ag hybrid nanoparticles (2 wt%) were added into the UV-curable acrylate resin matrices.

A Novel Valued Tolerance Rough Set and Decision Rules Method for Indoor Positioning Using WiFi Fingerprinting.

In recent years, due to the ubiquitous presence of WiFi access points in buildings, the WiFi fingerprinting method has become one of the most promising approaches for indoor positioning applications. However, the performance of this method is vulnerable to changes in indoor environments. To tackle this challenge, in this paper, we propose a novel WiFi fingerprinting method that uses the valued tolerance rough set theory-based classification method.

Tumor-induced Osteomalacia in a Boy with Maxillary Ossifying Fibroma.

Tumor-induced osteomalacia (TIO) is a rare, paraneoplastic disorder of hypophosphatemia associated with elevated tumor-produced fibroblast growth factor 23 (FGF23). Maxillofacial tumors are rarely involved in TIO, especially maxillary TIO in children. We present a 14-year-old boy with osteomalacia and high serum levels of FGF23, a hormone associated with decreased phosphate resorption, due to a maxillary tumor.

One-pot synthesis of S-scheme MoS/g-CN heterojunction as effective visible light photocatalyst.

Despite pioneering as the holy grail in photocatalysts, abundant reports have demonstrated that g-CN performs poor photocatalytic activity due to its high recombination rate of photo-induced charge carriers. Many efforts have been conducted to overcome this limitation in which the semiconductor-semiconductor coupling strategies toward heterojunction formation were considered as the easiest but the most effective method. Herein, a one-pot solid-state reaction of thiourea and sodium molybdate as precursors at different temperatures under N gas was applied for preparing composites of MoS/g-CN.

Polarization dependence of Cs 6S-6P-11S electromagnetically induced transparency at room temperature.

The effect of polarization on the ladder-type electromagnetically induced transparency (EIT) spectra of Cs atoms at room temperature for the transitions 6P-6P-11S is experimentally studied. The entire spectra with additional peaks arising from the Doppler effect are observed. As the relative angle between the probe's and coupling's plane of polarization arranges at 0, 45, and 90, the peak height ratio of 44'3" to 44'4" increases by more than 7 times with corresponding values of 0.

Developing cost-effective, highly active, and stable electrocatalysts for boosting electrochemical hydrogen evolution reaction (HER) in alkaline media is playing a critical role in meeting the demands of the hydrogen industry in the future. Herein, an efficient HER electrocatalyst based on flowerlike S-doped NiP mesoporous nanosheets (NSs) supported on nickel foam (S-NiP NSs/NF) was developed through an effective approach. The obtained S-NiP NSs/NF catalyst required low overpotential of only 87.

Objective: Estimating the genetic diversity and structures, both within and among chicken breeds, is critical for the identification and conservation of valuable genetic resources. In chickens, microsatellite (MS) marker polymorphisms have previously been widely used to evaluate these distinctions. Our objective was to analyze the genetic diversity and relationships among 22 chicken breeds in Asia based on allelic frequencies.

Synergistic Effect of NaCl Pretreatment and PVP on Browning Suppression and Callus Induction from Petal Explants of Pall. 'Festival Maxima'.

Browning is prevalent in tissue cultures of Pall. (herbaceous peony), and severely affects and restricts the growth and differentiation of the explants. In this study, dipping excised explants in a sodium chloride (NaCl) solution as a pretreatment, adding polyvinyl pyrrolidone (PVP) to the culture medium, storing planted explants at 4 °C for 24 h, and transferring planted explants to a new medium after 24 h were considered as browning-suppression methods in tissue cultures of herbaceous peony 'Festival Maxima'.
