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.

As an emerging two-dimensional (2D) Group-VA material, bismuth selenide (BiSe) exhibits favorable electrical and optical properties. Here, three distinct morphologies of BiSe were obtained from bulk BiSe through electrochemical intercalation exfoliation. And the morphologies of these nanostructures can be tuned by adjusting solvent polarity during exfoliation.

Objective: For patients with contraindications to hormone therapy, the absence of effective treatments for ovarian dysfunction post chemotherapy represents a critical issue requiring resolution. Local administration of mitochondria may enhance ovarian function in premature ovarian insufficiency (POI) by ameliorating diminished mitochondrial activity. Nevertheless, there is a paucity of literature on the efficacy of mitochondrial transplantation through intravenous injection, a less invasive and more convenient method than local injection, for the improvement of ovarian function in POI following chemotherapy.

Topical transdermal drug delivery for psoriasis remains a challenge because of the poor solubility of hydrophobic drugs and the limited penetration of the stratum corneum. In this study, a near-infrared (NIR) light-responsive thermosensitive hydrogel (PDLLA-PEG-PDLLA, PLEL)-based drug reservoir is developed that directly incorporated gold nanorods (GNRs) and methotrexate (MTX) in the sol state at low temperature, which is referred to as PLEL@GNR+MTX. The in vitro anti-psoriasis experiment indicated that, GNRs, as photothermal cores of composite hydrogel, not only triggered keratinocyte apoptosis but also promoted MTX release in a synergistic manner.

Bilayer graphene ribbons (GRs) hold great promise for the fabrication of next-generation nanodevices, thanks to unparalleled electronic properties, especially the tunable bandgap in association with twist angle, ribbon width, edge structure, and interlayer coupling. A common challenge in manufacturing bilayer GRs via templated chemical vapor deposition (CVD) approach is uncontrollable dewetting of micro- and nano-scaled patterned metal substrates. Herein, a confined CVD synthetic strategy of bilayer GR arrays is proposed, by utilizing the bifunctional Ni as a buffered adhesion layer to regulate the anisotropic dewetting of metal film in the V-groove and as a carbon-dissolution regulated metal to initiate the bilayer nucleation.

Chiral Aldehyde/Palladium Catalysis Enables Asymmetric Branched-Selective Ring-Opening Functionalization of Methylenecyclopropanes with Amino Acid Esters.

J Am Chem Soc

January 2025

Key Laboratory of Applied Chemistry of Chongqing Municipality and Chongqing Key Laboratory of Soft-Matter Material Chemistry and Function Manufacturing, School of Chemistry and Chemical Engineering, Southwest University, Chongqing 400715, China.

Achieving catalytic asymmetric functionalization of methylenecyclopropanes (MCPs) by selective C-C bond cleavage is a notable challenge due to the intricate reaction partners involved. In this work, we report that chiral aldehyde/palladium combined catalysis enables the asymmetric functionalization of MCPs with NH-unprotected amino acid esters. This reaction proceeds through a regiospecific branched ring-opening mechanism, resulting in optically active α,α-disubstituted α-amino acid esters bearing nonconjugated terminal alkene units.

Background: Alzheimer's disease (AD), the leading cause of dementia, is characterized by cognitive decline and the accumulation of amyloid-β (Aβ). It affects millions, with numbers expected to double by 2050. SMOC2, implicated in inflammation and fibrosis, may play a role in AD pathogenesis, particularly in microglial cell function, offering a potential therapeutic target.

The digital infrastructure has profoundly changed people's daily lives and health outcomes. However, the causal effect of digital infrastructure on cognitive health remains unclear. The study employs the "Broadband China" policy as a reliable proxy for digital infrastructure, using the China Health and Retirement Longitudinal Study (CHARLS) five waves panel data from 2011 to 2020 and a staggered difference-in-differences (DID) method to investigate the causal impact of digital infrastructure construction on the cognitive health in Chinese older adults.

Social anxiety undermines prosocial behaviors when required effort.

Int J Clin Health Psychol

December 2024

Research Center of Mental Health Education, Faculty of Psychology, Southwest University, Chongqing, 400715, China.

Social anxiety impairs interpersonal relationships, which rely heavily on prosocial behaviors essential for healthy social interactions. The influence of social anxiety on the dynamics of helping others, through stages of prosocial choice stimulus presentation and effort, is not well understood. This study combines two experiments that integrate effort-based decision-making tasks with electroencephalography to distinguish between the choice stimulus presentation and effort phases of prosocial behavior.

Visual semantic decoding aims to extract perceived semantic information from the visual responses of the human brain and convert it into interpretable semantic labels. Although significant progress has been made in semantic decoding across individual visual cortices, studies on the semantic decoding of the ventral and dorsal cortical visual pathways remain limited. This study proposed a graph neural network (GNN)-based semantic decoding model on a natural scene dataset (NSD) to investigate the decoding differences between the dorsal and ventral pathways in process various parts of speech, including verbs, nouns, and adjectives.

Osteoporosis is the most common systemic skeletal disorder, particularly associated with aging and postmenopausal women. With the growing knowledge about the gut-bone axis, the therapeutic strategies for osteoporosis have been shifted toward regulating gut microbiota to promote positive bone metabolism. Although GG (LGG) is widely reported to positively regulate bone metabolism by restoring the dysbiotic microbiome, oral administration is associated with sensitivity to gastric fluid and low bioavailability.

Background: Patients with non-small cell lung cancer (NSCLC) are prone to developing brain metastases (BMs), particularly those with epidermal growth factor receptor (EGFR) mutations. In clinical practice, treatment-naïve EGFR-mutant NSCLC patients with asymptomatic BMs tend to choose EGFR-tyrosine kinase inhibitors (TKIs) as first-line therapy and defer intracranial radiotherapy (RT). However, the effectiveness of upfront intracranial RT remains unclear.

To investigate the efficacy and mechanisms of fractional CO2 laser treatment for Vaginal Relaxation Syndrome (VRS) combined with recurrent bacterial vaginitis. Patients with VRS and recurrent bacterial vaginitis were randomly assigned to an intervention group (n = 60) receiving fractional CO2 laser therapy in addition to metronidazole, or a control group (n = 60) receiving metronidazole alone. Post-treatment assessments included vaginal relaxation, vaginal health index (VHI) scores, lactobacilli distribution, vaginal pH, recurrence rates, and the correlation between lactobacilli distribution and VHI.
