Case Report: A novel hemizygous missense variant in a Vietnamese boy with pyruvate dehydrogenase E1-alpha deficiency.

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.

Enhanced catalytic reduction through in situ synthesized gold nanoparticles embedded in glucosamine/alginate nanocomposites.

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.

Evaluating potential of H'mong chicken bone marrow-derived mesenchymal stem cells at different ages for primordial germ cells' feeder layer.

Primordial germ cells (PGCs) have potential applications in genetic conservation, vaccination, tissue repair therapies, and genetic research. Chicken bone marrow-derived mesenchymal stem cells (cbMSCs) is a good candidate for co-culture with PGCs. However, there is no consensus on the optimal age of donors.

High photocatalytic efficiency of a ZnO nanoplate/FeO nanospindle hybrid using visible light for methylene blue degradation.

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.

sp. DC2 is an endophytic fungus that was isolated from the stem of (L.) G.

Detection and molecular characterization of virulent Newcastle disease virus (subgenotype VII.2) in broiler chickens in Northern Vietnam.

Background And Aim: Newcastle disease (ND) is a major viral disease of poultry worldwide. However, data on the molecular characterization of Newcastle disease virus (NDV) in Vietnam are limited. This study aimed to identify the molecular characteristics of NDV strains from the vaccinated chickens farmed in Northern Vietnam.

Draft genome sequencing of halotolerant bacterium sp. DM10 unravels plant growth-promoting potentials.

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.

Comparative analysis of microRNA expression profiles in shoot and root tissues of contrasting rice cultivars (Oryza sativa L.) with different salt stress tolerance.

Rice is the second-most important primary crop in the world and one of the most susceptible crops to salt stress. Soil salinization hinders seedling growth and decreases crop yield by inducing ionic and osmotic imbalances, photosynthesis disturbances, cell wall alterations, and gene expression inhibition. Plants have developed a range of defense mechanisms to adapt to salt stress.

Integrated Change Detection and Classification in Urban Areas Based on Airborne Laser Scanning Point Clouds.

This paper suggests a new approach for change detection (CD) in 3D point clouds. It combines classification and CD in one step using machine learning. The point cloud data of both epochs are merged for computing features of four types: features describing the point distribution, a feature relating to relative terrain elevation, features specific for the multi-target capability of laser scanning, and features combining the point clouds of both epochs to identify the change.
