nT4X and nT4M: Novel Time Non-reversible Mixture Amino Acid Substitution Models.

One of the most important and difficult challenges in the research of molecular evolution is modeling the process of amino acid substitutions. Although single-matrix models, such as the LG model, are popular, their capability to properly capture the heterogeneity of the substitution process across sites is still questioned. Several mixture models with multiple matrices have been introduced and shown to offer advantages over single-matrix models.

Atmospheric pressure spatial atomic layer deposition of p-type CuO thin films from copper(II) acetylacetonate and ozone for UV detection.

Cupric oxide (CuO) is a promising p-type semiconducting oxide used in many critical fields, such as energy conversion and storage, and gas sensors, which is attributed to its unique optoelectrical properties and cost-effectiveness.

Contamination of retail market meat with extended-spectrum beta-lactamase genes in Vietnam.

The contamination of retail meat with antibiotic-resistant bacteria poses a substantial public health risk because of the potential spread of these bacteria within communities. The contamination of retail meat with extended-spectrum beta-lactamase (ESBL)-producing bacteria was investigated in four cities in Vietnam using real-time PCR, employing ESBL marker genes. This method provides a more comprehensive assessment of ESBL-producing bacterial contamination in meat samples than culture-based methods because it directly detects resistance genes from the extracted sample DNA.

Agingassociated challenges to persons living with HIV/AIDS in Vietnam: integrated perspectives from multiple stakeholders.

This study examined the aging-associated health and care needs among the HIV population in Vietnam, integrating perspectives from healthcare professionals, PLWH, and their caregivers. Qualitative data were collected through five focus group interviews involving ten PLWH, nine caregivers, and eight healthcare providers in Hanoi, Vietnam, in March 2023. Thematic analyses uncovered recurring patterns and themes across the three participant groups.

Presence of EGF ligand restricts the binding ability of EgB4 nanobody to EGFR extracellular domain.

EgB4 is a nanobody that could facilitate the development of drug-nanobody conjugates or drug delivery in cancer treatment due to its specific binding ability to the EGFR transmembrane protein. More significantly, EgB4 does not hamper the EGFR function and associates with EGFR in both the presence and absence of an EGF ligand. However, the difference in EgB4-EGFR interaction with and without EGF ligand is not clear.

Revealing a novel GI-19 lineage infectious bronchitis virus sub-genotype with multiple recombinations in South Korea using whole-genome sequencing.

Infectious bronchitis (IB), caused by the infectious bronchitis virus (IBV), is a highly contagious chicken disease, causing economic losses worldwide. New IBV strains and variants continue to emerge despite using inactivated and live-attenuated vaccines to prevent or control IB. In this study, the S1 genes of 46 IBV strains, isolated from commercial chicken flocks between 2003 and 2024 in Korea were sequenced and genetically characterized.

Burden and Risk Factors of Stroke in Vietnam from 1990 to 2021 - A Systematic Analysis from Global Burden Disease 2021.

Relating production and perception in two Raglai dialects at different stages of registrogenesis.

This paper explores the perception of two diachronically related and mutually intelligible phonological oppositions, the onset voicing contrast of Northern Raglai and the register contrast of Southern Raglai. It is the continuation of a previous acoustic study that revealed that Northern Raglai onset stops maintain a voicing distinction accompanied by weak formant and voice quality modulations on following vowels, while Southern Raglai has transphonologized this voicing contrast into a register contrast marked by vowel and voice quality distinctions. Our findings indicate that the two dialects partially differ in their use of identification cues, Northern Raglai listeners using both voicing and F1 as major cues while Southern Raglai listeners largely focus on F1.

Investigating polychlorinated alkanes in technical chlorinated paraffin mixtures and polymer products available in Vietnam.

Chlorinated paraffins (CPs) are chemical additives mostly composed of polychlorinated alkanes (PCAs) which may impact on the environment and human health; however, little is known about their presence in Southeast Asia. To fill this knowledge gap, we assessed 74 PCA homolog groups commonly referred to as short-chain (SCCPs: PCAs-C), medium-chain (MCCPs: PCAs-C), and long-chain CPs (LCCPs: PCAs-C) in technical CP mixtures (n = 4) and polymer samples (n = 49), including recycled plastics, collected in Vietnam in 2023. The contents of measured PCA homolog groups in technical CP mixtures were 86,000-930,000 mg/kg for PCAs-C; 85,000-990,000 mg/kg for PCAs-C; and 23,000-180,000 mg/kg for PCAs-C.
