A pyruvate dehydrogenase complex deficiency causes a reduction in adenosine triphosphate production and energy insufficiency, leading to neurological disorders. An abnormal E1-alpha protein originating from the gene with pathogenic variants is unable to communicate with E1-beta for the formation of the E1 enzyme, decreasing pyruvate dehydrogenase complex activity. In this study, we report a Vietnamese boy with lethargy, severe metabolic acidosis, increased serum lactate, hyperalaninemia, lactic acidosis, and globus pallidus lesions.

Precise tuning of ligands and a comprehensive understanding of their roles and functionalities are crucial for the design of nanoparticles (NPs) with tailored properties. In this study, we present the synthesis of copper NPs with precise control over their shape and crystallinity, relying on the remarkable versatility of oleylamine (OLA) as both a solvent and a ligand. By adjusting the temperature, OLA enables the formation of cubic NPs under rapid heating, reflecting kinetic control, and octahedral NPs with slow heating, indicating thermodynamic control.

Water pollution from dyes in wastewater is a critical global issue, as these stable organic dyes resist biodegradation, posing serious threats to aquatic ecosystems. To address this situation, advanced photocatalysts have been developed. Here, NiFeO/g-CN was synthesized for the photocatalytic degradation of Rhodamine B (RhB) dye in the presence of HO and visible light.

This study introduces a highly efficient and straightforward method for synthesizing gold nanoparticles (AuNPs) within a glucosamine/alginate (GluN/Alg) nanocomposite via an ionotropic gelation mechanism in aqueous environment. The resulting nanocomposite, AuNPs@GluN/Alg, underwent thorough characterization using UV-vis, EDX, FTIR, SEM, TEM, SAED, and XRD analyses. The spherical AuNPs exhibited uniform size with an average diameter of 10.

Article Synopsis
  • Traditional ways of making nanoparticles can be harmful to the environment, but using plant extracts is a safer and greener method for creating CoFeO nanoparticles.
  • These plant-based nanoparticles are very small, have special shapes, and can help fight germs and cancer in medical treatments.
  • They can also clean polluted water by removing harmful substances, but there are still some challenges to make this process work better on a larger scale.

Omental torsion is a medical condition characterized by the twisting of the omentum along its longitudinal axis, which leads to compromised blood flow. This condition is rarely diagnosed before surgery and can present symptoms similar to other causes of acute surgical abdomen. This report details a case of primary omental torsion initially suspected to be acute appendicitis.

HLA-B*58:01 and HLA-B*57 are protective alleles against HIV-1 subtype B or C infection whereas these HLA alleles have not been reported as protective in HIV-1 subtype AE infection. Although HLA-B*58:01-restricted and HLA-B*57-restricted HIV-1-specific CD8+ T cells have been thoroughly analyzed in subtype B or C infection, they have only been partially analyzed in subtype AE infection. We identified six HLA-B*58:01-restricted subtype AE epitopes in Vietnamese individuals infected with subtype AE.

In this work, ZnO nanoplates and FeO nanospindles were successfully fabricated a simple hydrothermal method using inorganic salts as precursors. The ZnO/FeO hybrid was fabricated using a mechanical mixture of two different ZnO : FeO weight ratios to investigate the effect of weight ratio on catalytic properties. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images showed that ZnO nanoplates (NPls) are about 20 nm thick with lateral dimensions of 100 × 200 nm, and FeO nanospindles (NSs) are about 500 nm long and 50 nm wide.

Article Synopsis
  • Vietnam's rising meat demand raises concerns about hepatitis E virus (HEV) reservoirs, particularly in pigs and wild boars, prompting this study to investigate HEV's presence in these animals.
  • Samples from 415 pigs and 102 wild boars were tested, revealing a 10% positivity rate overall, with wild boars showing a higher rate (25%) compared to domestic pigs (7%), and southern Vietnam having more cases than central Vietnam.
  • The study identified HEV-3a as the most common genotype, and the findings highlight the importance of wild boars as zoonotic reservoirs for HEV, suggesting a need for further research on its impact on human health.

Research suggests that many international students experience intimate partner violence (IPV) or sexual violence (SV) whilst attending tertiary institutions. Yet, little is known about how they engage in help-seeking and what types of support they need following IPV/SV. In this paper, we present findings from a qualitative analysis of 30 in-depth interviews with international student women who experienced SV/IPV while studying in Australia.

While durian shell is often discharged into landfills, this waste can be a potential and zero-cost raw material to synthesize carbon-based adsorbents with purposes of saving costs and minimizing environmental contamination. Indole (IDO) is one of serious organic pollutants that influence aquatic species and human health; hence, the necessity for IDO removal is worth considering. Here, we synthesized a magnetic composite, denoted as MFOAC, based on activated carbon (AC) derived from durian shell waste incorporated with MnFeO (MFO) to adsorb IDO in water.

Toxic organic dyes-containing wastewater treatment by adsorption and photocatalytic techniques is widely applied, but adsorbents and photocatalysts are often synthesized through chemical methods, leading to secondary pollution by released chemicals. Here, we report a benign method using Tecoma stans floral extract to produce MgFeO/ZnO (MGFOZ) nanoparticles for adsorption and photocatalytic degradation of coomassie brilliant blue (CBB) dye. Green MGFOZ owned a surface area of 9.

In this study, strain DM10 was isolated from mangrove roots and characterized as a halotolerant plant growth-promoting bacterium. Strain DM10 exhibited the ability to solubilize phosphate, produce siderophore, show 1-aminocyclopropane-1-carboxylic acid deaminase activity, and hydrolyze starch. The rice plants subjected to a treatment of NaCl (200 mM) and inoculated with strain DM10 showed an improvement in the shoot length, root length, and dried weight, when compared to those exposed solely to saline treatment.
