Highly efficient and thermally stable cyan-emitting ZnS/ZnO phosphors for full-visible-spectrum LED lighting.

Near-ultraviolet (NUV)-pumped white light-emitting-diodes (WLEDs) often suffer from poor color rendering in the 480-520 nm range, highlighting the need for an efficient cyan phosphor with strong absorption at 370-420 nm. This study presents the successful synthesis of cyan-emitting ZnS/ZnO phosphors using a high-energy planetary ball milling method followed by post-annealing. The fabricated phosphors, with particle sizes ranging from 1 to 3 μm, exhibit strong cyan emission with CIE chromaticity coordinates of (0.

Identifying fecal microbiota signatures of colorectal cancer in a Vietnamese cohort.

Background: Colorectal cancer (CRC) is among the top three causes of global cancer mortality. In Vietnam, CRC is the third leading cause of death in women and the fourth cause of cancer mortality in men. A large number of metagenomic studies have reported the relationship between altered composition and function of the gut microbiota with CRC, but this relationship in low- and middle-income countries including Vietnam (with an estimated population of 100.

An appropriate DNA input for bisulfite conversion reveals LINE-1 and Alu hypermethylation in tissues and circulating cell-free DNA from cancers.

The autonomous and active Long-Interspersed Element-1 (LINE-1, L1) and the non-autonomous Alu retrotransposon elements, contributing to 30% of the human genome, are the most abundant repeated sequences. With more than 90% of their sequences being methylated in normal cells, these elements undeniably contribute to the global DNA methylation level and constitute a major part of circulating-cell-free DNA (cfDNA). So far, the hypomethylation status of LINE-1 and Alu in cellular and extracellular DNA has long been considered a prevailing hallmark of ageing-related diseases and cancer.

Hypermethylation at 45S rDNA promoter in cancers.

The ribosomal genes (rDNA genes) encode 47S rRNA which accounts for up to 80% of all cellular RNA. At any given time, no more than 50% of rDNA genes are actively transcribed, and the other half is silent by forming heterochromatin structures through DNA methylation. In cancer cells, upregulation of ribosome biogenesis has been recognized as a hallmark feature, thus, the reduced methylation of rDNA promoter has been thought to support conformational changes of chromatin accessibility and the subsequent increase in rDNA transcription.

Research Design And Methods: At 19 sites, adults with type 1 diabetes were randomly assigned to TI plus insulin degludec (N = 62) or usual care (UC) with continuation of prestudy insulin delivery method (N = 61) for 17 weeks.

Results: Prestudy, AID was used by 48% and MDI by 45%.

From SMILES to Enhanced Molecular Property Prediction: A Unified Multimodal Framework with Predicted 3D Conformers and Contrastive Learning Techniques.

We present a novel molecular property prediction framework that requires only the SMILES format as input but is designed to be multimodal by incorporating predicted 3D conformer representations. Our model captures comprehensive molecular features by leveraging both the sequential character structure of SMILES and the three-dimensional spatial structure of conformers. The framework employs contrastive learning techniques, utilizing InfoNCE loss to align SMILES and conformer embeddings, along with task-specific loss functions, such as ConR for regression and SupCon for classification.

However, a significant outbreak of quartan malaria caused by occurred in Khanh Vinh District, Khanh Hoa Province, Vietnam in 2023 and the outbreak persists. In this report, we present the epidemiological and clinical characteristics of this unprecedented outbreak of quartan malaria in Vietnam.

Dataset on Vietnamese students' impulse buying behavior on TikTok shop.

This article aims to provide a dataset on the factors affecting the online impulse buying behavior of university and college students in Vietnam. The examined factors include scarcity (SC), serendipity information (SI), trust (TR), hedonic motivation (HM), shopping lifestyle (SL), and product presentation (PP). In particular, the survey focuses on impulse shopping behavior on TikTok Shop, a rapidly growing e-commerce platform that is increasingly popular among Generation Z in Vietnam and other Asian countries.

Creeping Fat-Derived Free Fatty Acids Induce Hyperplasia of Intestinal Muscularis Propria Muscle Cells: A Novel Link Between Fat and Intestinal Stricture Formation in Crohn's Disease.

Background & Aims: In Crohn's disease, wrapping of mesenteric fat around the bowel wall, so-called "creeping fat," is highly associated with strictures. The strongest contributor to luminal narrowing in strictures is a thickening of the human intestinal muscularis propria (MP). We investigated creeping fat-derived factors and their effect on mechanisms of human intestinal MP smooth muscle cell (HIMC) hyperplasia.

Case report: A rare case of multifocal, combined lymphatic-venous malformation.

Vascular malformations, including lymphatic-venous malformations (LVMs), are complex and can lead to significant morbidity. This case report details the management of a rare multifocal, combined LVM in a 3-month-old male, misdiagnosed as a right inguinal hernia prenatally. Postnatal imaging revealed multiloculated cystic masses extending from the mons pubis to the right groin, scrotum, and thigh.

Angiotensin-Converting Enzyme Inhibitor Washout Period Prior to Angiotensin Receptor/Neprilysin Inhibitor Initiation in the Inpatient Setting.

Background: The 2022 AHA-ACC HFSA Guideline for Management of Heart Failure recommend initiating an angiotensin receptor/neprilysin inhibitor (ARNI) in patients with heart failure with reduced ejection fraction (HFrEF) who can tolerate an angiotensin-converting enzyme inhibitor (ACEi). The manufacturer recommends initiating a 36-hour washout period when switching from ACEi to ARNI due to an increased risk of adverse effects, including angioedema. This study investigated the adherence to the washout period when transitioning from ACEi to ARNI at a community hospital.

Named entity recognition of pharmacokinetic parameters in the scientific literature.

The development of accurate predictions for a new drug's absorption, distribution, metabolism, and excretion profiles in the early stages of drug development is crucial due to high candidate failure rates. The absence of comprehensive, standardised, and updated pharmacokinetic (PK) repositories limits pre-clinical predictions and often requires searching through the scientific literature for PK parameter estimates from similar compounds. While text mining offers promising advancements in automatic PK parameter extraction, accurate Named Entity Recognition (NER) of PK terms remains a bottleneck due to limited resources.

Exploring single-mode VCSEL wavelength tuning for low-cost 3D optical coherence tomography and OCT angiography.

Low-cost optical coherence tomography has recently emerged as a growing field due to the increased need for general availability of OCT devices outside of the clinics. One of the main obstacles in creating low-cost SS-OCT systems is the price of the laser. In this work, we study the influence of different tuning parameters (e.
