Reconstructing suspended sediment concentrations in the Mekong River Basin via semi-supervised-based deep neural networks.

The Mekong River Basin (MRB) is crucial for the livelihoods of over 60 million people across six Southeast Asian countries. Understanding long-term sediment changes is crucial for management and contingency plans, but the sediment concentration data in the MRB are extremely sporadic, making analysis challenging. This study focuses on reconstructing long-term suspended sediment concentration (SSC) data using a novel semi-supervised machine learning (ML) model.

Theoretical Analysis of Superior Photodegradation of Methylene Blue by Cerium Oxide/Reduced Graphene Oxide vs. Graphene.

Density functional theory and a semi-empirical quantum chemical approach were used to evaluate the photocatalytic efficiency of ceria (CeO) combined with reduced graphene oxide (rGO) and graphene (GP) for degrading methylene blue (MB). Two main aspects were examined: the adsorption ability of rGO and GP for MB, and the separation of photogenerated electrons and holes in CeO/rGO and CeO/GP. Our results, based on calculations of the adsorption energy, population analysis, bond strength index, and reduced density gradient, show favorable energetics for MB adsorption on both rGO and GP surfaces.

New Cytotoxic Sesquiterpene Lactones from the Leaves of Tithonia Diversifolia and their Apoptosis Effect Evaluation in KB Cancer Cells.

From the leaves of Tithonia diversifolia, nine sesquiterpenoids (1-9), including two new ones (tagitinin J (1) and tagitinin K (2)) were isolated and structurally determined. Their chemical structures were elucidated by extensive analyses of the HRESIMS and NMR spectral data, as well as comparison with the literature. All of the isolated compounds (except compounds 7-9) significantly exhibited cytotoxic activity against four human cancer cell lines (KB, HepG2, A549 and MCF7), with IC values ranging from 0.

Robust interaction of ZnO and TiO nanoparticles with layered graphitic carbon nitride for enhanced photocatalytic oxidative desulfurization of fuel oil: mechanism, performance and stability.

Sulfur compounds in fuel such as thiophene, benzothiophene and dibenzothiophene are the primary source of SO emissions, leading to environmental pollution and acid rain. In this study, we synthesized a layered oxygen-doped graphitic carbon nitride (OCN) structure and integrated ZnO and TiO nanoparticles onto the OCN surface through a microwave-assisted sol-gel method. The X-ray photoelectron spectroscopy (XPS) and density functional theory (DFT) results confirmed a robust interaction between the ZnO and TiO nanoparticles and the oxygen-doped g-CN (OCN) surface, as indicated by the formation of C-N-Ti and C-O-Ti bonds.

Graphitic carbon nitride supported silver nanoparticles (AgNPs/g-CN): synthesis and photocatalytic behavior in the degradation of 2,4-dichlorophenoxyacetic acid.

Graphitic carbon nitride supported silver nanoparticles (AgNPs/g-CN) with 1%, 3%, and 5% AgNPs were successfully synthesized by an "" method with ultrasound of a mixture of AgNP solution and g-CN.

Comprehensive Study on the Adsorption and Degradation of Dichlorodiphenyltrichloroethane on Bifunctional Adsorption-Photocatalysis Material TiO/MCM-41 Using Quantum Chemical Methods.

The adsorption and degradation capacities of dichlorodiphenyltrichloroethane (DDT) on a photocatalyst composed of TiO supported on the mesoporous material MCM-41 (TiO/MCM-41) were investigated using density functional theory and real-time density functional theory methods. The van der Waals interactions within the PBE functional were adjusted by using the Grimme approach. The adsorption of DDT was evaluated through analyses involving adsorption energy, Hirshfeld atomic charges, Wiberg bond orders, molecular electrostatic potential, noncovalent interaction analysis, and bond path analysis.

Computational, optical and feasibility studies of organic luminescence TMB-PPT blend for photovoltaic application.

For enhanced applications of solar cells, organic luminescence materials like long persistent luminescence (LPL) present one of the promising avenues for light enhancement. Currently, most existing luminescent materials are based on an inorganic system that requires rare elements such as europium and dysprosium, with a very high processing temperature. Adopting organic luminescence materials that are free from rare elements is necessary, considering the low-temperature fabrication and low material cost.

Developmental transcriptomes predict adult social behaviours in the socially flexible sweat bee, Lasioglossum baleicum.

Natural variation can provide important insights into the genetic and environmental factors that shape social behaviour and its evolution. The sweat bee, Lasioglossum baleicum, is a socially flexible bee capable of producing both solitary and eusocial nests. We demonstrate that within a single nesting aggregation, soil temperatures are a strong predictor of the social structure of nests.

Health staff perceptions of patient safety and associated factors in hospitals in Vietnam.

Introduction: Patient safety is a global challenge of preventing and mitigating medical errors which might harm patients during their course of treatment and care. This study was employed to contribute to the existing literature aimed to assess patient safety culture among health staff and to determine predictors of health staff perceptions of patient safety in hospitals in Vietnam.

Methods: A cross-sectional study was conducted in three hospitals of Vietnam with a total of 763 participants.

Development of Anti-OSCAR Antibodies for the Treatment of Osteoarthritis.

Osteoarthritis (OA) is the most common joint disease that causes local inflammation and pain, significantly reducing the quality of life and normal social activities of patients. Currently, there are no disease-modifying OA drugs (DMOADs) available, and treatment relies on pain relief agents or arthroplasty. To address this significant unmet medical need, we aimed to develop monoclonal antibodies that can block the osteoclast-associated receptor (OSCAR).

Construction of Rabbit Immune Antibody Libraries.

Rabbits have distinct advantages over mice as a source of target-specific antibodies. They produce higher affinity antibodies than mice and may elicit strong immune response against antigens or epitopes that are poorly immunogenic or tolerated in mice. However, a great majority of currently available monoclonal antibodies are of murine origin because of the wider availability of murine fusion partner cell lines and well-established tools and protocols for fusion and cloning of mouse hybridoma.

Antimicrobial, Cytotoxic, and -Glucosidase Inhibitory Activities of Ethanol Extract and Chemical Constituents Isolated from Propolis-In Vitro and Molecular Docking Studies.

The chemical investigation of propolis collected in Binh Dinh province, Vietnam, led to the isolation of nine compounds, including four sesquiterpenes: spathulenol (), 1H,5H-aromandendrane-4,10-diol (), 1,6-dihydroxy-4(15)-eudesmene (), and 1H,5H-aromandendrane-4,10-diol (); three triterpenes: acetyl oleanolic acid (), 3-hydroxytirucalla-8,24-dien-21-oic acid (), and ursolic acid (); and two xanthones: cochinchinone A () and -mangostin (). Sesquiterpens - and triterpene were isolated for the first time from stingless bee propolis. Plants in the and genus were suggested as resin sources of the propolis sample.

Group size rather than social status influences personal immune efficacy in a socially polymorphic bee.

The evolution of group living is associated with increased pressure from parasites and pathogens. This can be offset by greater investment in personal immune defences and/or the development of cooperative immune defences (social immunity). An enduring question in evolutionary biology is whether social-immune benefits arose in response to an increased need in more complex societies, or arose early in group living and helped facilitate the evolution of more complex societies.

Statin Use and Incidence of Parkinson's Disease in Women from the French E3N Cohort Study.

Background: Statins represent candidates for drug repurposing in Parkinson's disease (PD). Few studies examined the role of reverse causation, statin subgroups, and dose-response relations based on time-varying exposures.

Objectives: We examined whether statin use is associated with PD incidence while attempting to overcome the limitations described previously, especially reverse causation.
