Enhancing Water Electrolysis through Interfacial Design of Nickel Foam.

Water electrolysis recognizes nickel foam (NF) as an effective current collector due to its excellent conductivity. However, recent studies highlighted NF's effect on the efficacy of various electrocatalytic reactions, primarily due to the presence of electroactive chemical species at its interface. In contrast, numerous reports suggested that NF has a negligible impact on overall electrocatalytic activity.

Cbl-b inhibition improves manufacturing efficiency and antitumoral efficacy of anti-CD19 CAR-T cells.

Chimeric antigen receptor T (CAR-T) cells represent a promising approach for cancer immunotherapy, yet their efficacy is hindered by immunosuppressive signals in the tumor microenvironment.

Numerous studies have explored the genetic and molecular mechanisms regulating VW resistance in cotton, but the role and mechanism of strigolactone (SL) is still elusive. We investigated the function of SL in cotton's immune response to V.

Mechanism for Adsorption, Dissociation, and Diffusion of Hydrogen in High-Entropy Alloy AlCrTiNiV: First-Principles Calculation.

To investigate hydrogen behaviors in the high-entropy alloy AlCrTiNiV, density functional theory and transition state theory were used to explore the molecular H2 absorption and dissociation and the atomic H adsorption, diffusion, and penetration progress. The H2 molecule, where the H-H band is parallel to the surface layer, is more inclined to absorb on the top site of the Ti atom site of first atomic layer on the AlCrTiNiV surface, then diffuse into the hollow sites, through the bridge site, after dissociating into two H atoms. Atomic H is more likely to be absorbed on the hollow site.

Hydrogen peroxide serves as pivotal fountainhead for aerosol aqueous sulfate formation from a global perspective.

Traditional atmospheric chemistry posits that sulfur dioxide (SO) can be oxidized to sulfate (SO) through aqueous-phase reactions in clouds and gas-phase oxidation. Despite adequate knowledge of traditional mechanisms, several studies have highlighted the potential for SO oxidation within aerosol water. Given the widespread presence of tropospheric aerosols, SO production through aqueous-phase oxidation in aerosol water could have a pervasive global impact.

Spatial multi-omics at subcellular resolution via high-throughput in situ pairwise sequencing.

Technology for spatial multi-omics aids the discovery of new insights into cellular functions and disease mechanisms. Here we report the development and applicability of multi-omics in situ pairwise sequencing (MiP-seq), a method for the simultaneous detection of DNAs, RNAs, proteins and biomolecules at subcellular resolution. Compared with other in situ sequencing methods, MiP-seq enhances decoding capacity and reduces sequencing and imaging costs while maintaining the efficacy of detection of gene mutations, allele-specific expression and RNA modifications.

Single-Cell Transcriptional Profile Construction of Rat Pituitary Glands before and after Sexual Maturation and Identification of Novel Marker in Gonadotropes.

The mammalian pituitary gland drives highly conserved physiological processes such as somatic cell growth, pubertal transformation, fertility, and metabolism by secreting a variety of hormones. Recently, single-cell transcriptomics techniques have been used in pituitary gland research. However, more studies have focused on adult pituitary gland tissues from different species or different sexes, and no research has yet resolved cellular differences in pituitary gland tissue before and after sexual maturation.

The Role of the Gene in Porcine Muscle Development and Its Molecular Regulatory Mechanisms.

Muscle growth stands as a pivotal economic trait within pig production, governed by a complex interplay of multiple genes, each playing a role in its quantitative manifestation. Understanding the intricate regulatory mechanisms of porcine muscle development is crucial for enhancing both pork yield and quality. This study used the GSE99749 dataset downloaded from the GEO database, conducting a detailed analysis of the RNA-seq results from the longissimus dorsi muscle (LD) of Tibetan pigs (TP), Wujin pigs (WJ) and large white pigs (LW) at 60 days of gestation, representing diverse body sizes and growth rates.

GnRH-driven FTO-mediated RNA mA modification promotes gonadotropin synthesis and secretion.

Background: Gonadotropin precisely controls mammalian reproductive activities. Systematic analysis of the mechanisms by which epigenetic modifications regulate the synthesis and secretion of gonadotropin can be useful for more precise regulation of the animal reproductive process. Previous studies have identified many differential mA modifications in the GnRH-treated adenohypophysis.

Upregulated lncRNA PRNT promotes progression and oxaliplatin resistance of colorectal cancer cells by regulating HIPK2 transcription.

Background: Colorectal cancer (CRC) is the third most common cancer and a significant cause of cancer-related mortality globally. Resistance to chemotherapy, especially during CRC treatment, leads to reduced effectiveness of drugs and poor patient outcomes. Long noncoding RNAs (lncRNAs) have been implicated in various pathophysiological processes of tumor cells, including chemotherapy resistance, yet the roles of many lncRNAs in CRC remain unclear.

Specifically targeting antimicrobial peptides for inhibition of Candidatus Liberibacter asiaticus.

Aims: Huanglongbing (citrus greening) is a plant disease putatively caused by the unculturable Gram-negative bacterium Candidatus Liberibacter asiaticus (CLas), and it has caused severe damage to citrus plantations worldwide. There are no definitive treatments for this disease, and conventional disease control techniques have shown limited efficacy. This work presents an in silico evaluation of using specifically targeting anti-microbial peptides (STAMPs) consisting of a targeting segment and an antimicrobial segment to inhibit citrus greening by inhibiting the BamA protein of CLas, which is an outer membrane protein crucial for bacterial viability.

Identification of Fungicide Combinations for Overcoming and Fungicide Resistance.

Fungal diseases, including downy mildew (caused by ) and gray mold (caused by ), significantly impact the marketable yield of grapes produced worldwide. Cytochrome b of the mitochondrial respiratory chain of these two fungi is a key target for Quinone outside inhibitor (QoI)-based fungicide development. Since the mode of action (MOA) of QoI fungicides is restricted to a single site, the extensive usage of these fungicides has resulted in fungicide resistance.

However, circRNAs have not been systematically identified in breast cancer (BC) as crucial regulators in multitudinous biological processes. This study is conducted to explore novel circRNAs in BC and the corresponding mechanisms of their action.

Human leukocyte antigen-G 14 bp insertion/deletion polymorphism contributes to preeclampsia risk in Asian population: A systematic review and meta‑analysis.

Preeclampsia remains enigmatic and responsible for vast maternal and fetal morbidity and mortality worldwide. Our objective was to assess the strength of the effect of the 14 bp deletion/insertion polymorphism in exon 8 of the 3'UTR region of the human leukocyte antigen-G (HLA-G) gene on preeclampsia risk across different populations. A systematic review by a meta-analysis was performed to summarize the scattered epidemiologic evidence, which remains inconclusive and controversial.
