Aims And Objectives: To evaluate the efficacy of treatment following coronectomy on mandibular third molars with inferior alveolar nerve (IAN) involvement.

Methods: A cross-sectional descriptive analysis was done on the mandibular third molars of 37 people (≥ 18 years old, 28 males, and 9 females) who needed a coronectomy and had a confirmed diagnosis of IAN in groups I, II, and III according to the classification of Q. Luo 2018, as found by CBCT.

Primary closure compared with T-tube drainage following laparoscopic common bile duct exploration among elderly patients with hepatolithiasis and/or choledocholithiasis: a comparative study using a propensity score matching.

Background: Laparoscopic common bile duct exploration (LCBDE) is commonly used for hepatolithiasis and/or choledocholithiasis, but the ideal method for common bile duct closure remains uncertain, especially for elderly patients (≥65 years). This study compared outcomes of primary closure versus T-tube drainage following LCBDE in elderly patients.

Methods: Data from elderly patients undergoing LCBDE for hepatolithiasis and/or choledocholithiasis between May 2016 and December 2020 at two Vietnamese hospitals were analyzed.

Gold nanotube self-assemblage from tubular W@Au cluster.

Context: While the pure Au cluster tends to exist in a 3D cage shape, the doubly doped W@Au is found to prefer a tubular form containing three five-membered Au rings stabilized by the W dimer vertically placed inside a tube-like Au framework. Formation of self-assembled nanotubes containing five-membered Au rings from the tube-like W@Au cluster is also feasible, and such a tubular structure constitutes an ideal building block for generating gold-assembled nanotubes, providing us with a useful approach for designing some novel tailor-made materials with interesting optoelectronic properties.

Methods: Density functional theory (DFT) calculations using the TPSS functional and the cc-pVDZ-PP basis set are employed to determine some noticeable effects of the doping of the W dimer on the structure, stability, and optical properties of pure Au16 gold clusters.

Value of transabdominal ultrasonography for diagnosing functional constipation in children: a systematic review and meta-analysis.

Transabdominal ultrasonography is increasingly used as a novel modality for detecting pediatric functional constipation (FC). This systematic review and meta-analysis aimed to assess the diagnostic parameters of FC including rectal diameter (RD) and anterior rectal wall thickness. A systematic search was conducted of the Ovid MEDLINE, EMBASE, Scopus, and PubMed databases through September 29, 2023, to identify studies comparing RD and anterior wall thickness using transabdominal ultrasonography in children with versus without FC.

Antibiotic resistance genes, colistin-resistant Escherichia coli, and physicochemicals in health care wastewater in Vinh Long General Hospital, Vietnam.

This study collected ten treated wastewater samples from Vinh Long General Hospital to determine their physicochemical characteristics and antibiotic properties. All treated wastewater samples collected during the monitoring periods complied with national regulations. In addition, these samples did not contain bacteria such as Salmonella, Shigella, and Vibrio cholerae.

Enhanced Anti-inflammatory Effects of Diclofenac Delivered Orally via Polyvinylpyrrolidone K30/Silk Fibroin Nanoparticles in a Murine Model of Carrageenan-Induced Paw Edema.

Diclofenac has a relatively low oral bioavailability (50-60 %) and is quickly metabolized with a half-life of less than 1 h. Therefore, the oral therapeutic effect of diclofenac is not optimal. This research developed polyvinylpyrrolidone K30-functionalized silk fibroin nanoparticles as an effective delivery system for diclofenac (FNPs-PVP-DC).

Evaluating the effectiveness of an autogenous vaccine to prevent motile Aeromonas septicaemia in striped catfish (Pangasianodon hypophthalmus) formulated by using DNA fingerprints for bacterial inclusion.

Many Aeromonas species are infecting striped catfish in the Mekong Delta in Vietnam. This study aimed to evaluate the effectiveness of autogenous vaccines developed by analysing the genetic diversity through DNA fingerprint analysis. A total of 38 Aeromonas strains isolated from 2017 to 2022 were analysed for phenotypic differences using the repetitive element sequence PCR (rep-PCR) with the (GTG) single-primer.

Facile Synthesis of 1,2-Disubstituted Benzimidazoles as Potent Cytotoxic Agents.

Benzimidazoles have a broad spectrum of biological and pharmacological properties, including anticancer activity. This study reports the facile synthesis and cytotoxic evaluation of twenty-eight 1,2-disubstituted benzimidazoles (6a-β), based on condensation reactions between N-benzyl o-phenylenediamine and benzylamine. The reactions were solvent-free, with the use of NaSO as an inexpensive and environmentally friendly oxidizing agent, and progressed rapidly.

Ovarian traits, spawning pattern and season, length at first maturity, and batch fecundity of (Bleeker, 1852) caught from the Vietnamese Mekong Delta.

has a wide range of distribution, from brackish to freshwater water, ranging from India to the Philippines and Fiji, including the Vietnamese Mekong Delta (VMD), where it lives mainly in the coastal regions and plays a vital role in food supply. Our preliminary observation showed that its population tended to decline, but little is known about this species. This study, therefore, was conducted to provide data on the ovarian structure, spawning pattern and season, length at first maturity, and batch fecundity of this fish.

Inhibitory effects of -cinnamoyltyramine on growth of invasive weeds and weedy rice.

-cinnamoyltyramine (NTCT) has been identified from an allelopathic Vietnamese rice accession OM 5930. This study employed bioassays to analyze NTCT's effects on shoot and root growth of multiple test and weed species. NTCT demonstrated potent inhibitory effects on cress, lettuce, canola, palmer amaranth, timothy, barnyardgrass, red sprangletop, and weedy rice, with increasing concentrations leading to substantial reductions in growth in all species.

A solvent-free and catalyst-free reaction of -aminobenzophenone with aryl isothiocyanates: expedient access to congested 4-phenyl-4-hydroxyquinazolin-2-thione derivatives.

An efficient method to construct 4-phenyl-4-hydroxyquinazolin-2-thiones 3 solvent-free and catalyst-free addition of -aminobenzophenone 1 with aryl isothiocyanates 2 under thermal conditions has been developed, providing new congested 4-phenyl-4-hydroxyquinazolin-2-thiones 3 in practically quantitative yields simple purification by filtration/recrystallization. Extension of these conditions to -aminoacetophenone 4 in place of -aminobenzophenone 1 led to 4-methylenequinazoline-thione 5 as a result of a subsequent dehydration reaction.
