Yield-limiting nutrient response of lowbush blueberry grown in recent and ancient alluvial soils of the Mekong Delta.

Background: Blueberries are ornamental plants grown in pots in many yards in the Mekong Delta (MD) region. In this region, the recent alluvial (RA) soil is fertile and ancient alluvial (AA) soil is considered degraded because it only has around a quarter of the nutrient content of the RA soil. Both soils have a high clay content, so organic matter is needed to improve their physical condition.

Tube-like Gold Clusters M@Au (M = W, Mo; = 0, ±1): Structure, Electronic Property, and Optical Nonlinearity.

Density functional theory (DFT) calculations are carried out to determine the geometries and electronic and nonlinear optical (NLO) properties of the doubly doped gold clusters in three charge states M @ Au with M = W, Mo and = 0, ±1. At their lowest-lying equilibrium structures, the impurities that are vertically encapsulated inside a cylindrical gold framework, significantly enhance the stability and modify properties of the host. The presence of M units results in the formation of a tube-like ground state, which is identified for the first time for gold clusters.

A systematic study of TMO (TM = V, Cr, Mn, and Fe; = 3 and 6) clusters embedded in a PtS monolayer.

Doping-based magnetism engineering is an effective approach to synthesize new multifunctional two-dimensional (2D) materials from their non-magnetic counterparts. In this work, doping with TMO clusters (TM = V, Cr, Mn, and Fe; = 3 and 6) is proposed to induce feature-rich electronic and magnetic properties in a PtS monolayer. The pristine monolayer is a non-magnetic semiconductor with an indirect energy gap of 1.

Effects of Organic Substrate Amendments on Selected Organic Fractions and Biochemical Parameters under Different Soils.

The application of organic substrates can affect soil respiration, dehydrogenase (DH-ase) activity, dissolved organic carbon (DOC), and humic acid (HA) fractions. This study aimed to evaluate the effects of five organic substrates in the organic fractions of degraded alluvial soil, acid sulfate soil, and sandy soils and the physicochemical properties of the soil. Soil samples were amended at a rate of 5 tons ha with (1) water hyacinth compost, (2) sugarcane filter cake compost, (3) biogas sludge-rice straw compost, (4) vermicompost, and (5) sludge.

Safety evaluation of seeds: a metabolomic profiling and network toxicology approach.

Sacha Inchi () seeds and oil have been integrated into daily diets. However, scientific reports have raised concerns regarding potential health risks associated with saponins and alkaloids in this seeds. This study employed a combination analysis using proton-NMR, GC-MS, LC-QTOF, and GNPS molecular networking to evaluate the chemical composition of these seeds.

Genotype-driven therapeutics in DEE and metabolic epilepsy: navigating treatment efficacy and drug resistance.

Neonatal intensive care unit (NICU), particularly in treating developmental and epileptic encephalopathy (DEE) and metabolic epilepsy (ME), requires a deep understanding of their complex etiologies and treatment responses. After excluding treatable cases such as infectious or autoimmune encephalitis, our focus shifted to a more challenging subgroup of 59 patients for in-depth genetic analysis using exome sequencing (ES). The ES analysis identified 40 genetic abnormalities, significantly including de novo variants.

Optimization of Vitamin B1, B2, and B6 Absorption in Nang Tay Dum Floating Rice Grains.

As reported by the FAO, in 2022, approximately 735 million people experienced undernourishment, underscoring the critical need for effective strategies to address micronutrient deficiencies. Among these strategies, the mass fortification of staple foods, particularly rice-a dietary staple for half of the global population-has emerged as one of the most effective approaches. Conventional milling processes diminish the nutritional content of rice, necessitating the development of fortification methods to enhance its nutrient profile.

Left ventricular thrombus in patient with nonischemic cardiomyopathy: A case report.

Left ventricular thrombus (LVT) is a severe consequence that typically follows acute myocardial infarction (MI) and can occur in nonischemic cardiomyopathies. In patients who have experienced an ST-segment elevation acute myocardial infarction (STEMI), LVT is seen up to 15% of the time; for patients without an ischemic cardiomyopathy, it is only 2% to 36% of the time. According to Virchow's triad, the cornerstone of LVT formation includes endothelial injury, blood stasis, and hypercoagulability.
