The electrochemical reduction of CO to formic acid or formate represents one of the most economically promising route for CO utilization. While substantial advances in catalyst design and electrolyzer engineering have been achieved in recent years, critical uncertainties remain regarding the reaction pathway and the often-debated role of alkali metal cations. Resolving these discrepancies requires precise kinetic analysis under well-defined conditions.

Global warming and eutrophication have synergistically intensified cyanobacterial blooms, with Microcystis posing significant ecological and health risks due to microcystin (MC) production. This study investigated how temperature gradients (10 °C, 25 °C, 35 °C, 40 °C) modulate physiological, morphological, and molecular adaptive strategies in M. aeruginosa, focusing on metabolic trade-offs between morphological plasticity and toxin production.

Renal ischemia-reperfusion injury (RIRI), a major contributor to acute kidney injury (AKI) and delayed graft function (DGF), is closely associated with dysregulation of metal ion homeostasis. Although copper and iron metabolism exhibit interconnected regulatory pathways, the temporal dynamics and functional interplay of these metal ions in RIRI pathogenesis remain poorly understood. Our study demonstrates that cuproptosis and ferroptosis, two distinct forms of cell death induced by metal ion overload, occur simultaneously within 6 h after reperfusion.

However, their robustness can be seriously degraded when fine-tuning them in real-world scenarios. This paper investigates fine-tuning stereo matching and optical flow estimation networks without compromising their robustness to unseen domains.

Exercise alleviates high fat diet (HFD)-induced glycolipid metabolism disorders, but the mechanisms are not discovered totally. Low androgen/androgen receptor (AR) levels are associated with glycolipid metabolism disorders in males, and androgen/AR modulate glycolipid metabolism-related regulators such as peroxisome proliferator-activated receptor gamma coactivator 1 alpha (PGC1-α), Forkhead box O1 (FoxO1), phosphoenolpyruvate carboxy kinase (PEPCK) and stearyl-coenzyme A desaturase 1 (SCD1). In the present study, we blockaded androgen (by castration) and inhibited or activated AR activity (by AR antagonist flutamide and agonist S4, respectively) to clarify androgen/AR's roles in exercise-induced alleviation of glycolipid metabolism disorders in male high fat diet (HFD) feeding mice and the underlying mechanisms.

Metal organic framework (MOF)-based mixed-matrix membranes (MMMs), which embed MOF particles in polymer matrices, combine the advantages of polymeric and inorganic membranes. Multiple previous studies have used the Maxwell model together with molecular simulations and machine learning (ML) to predict the performance of MOF/polymer MMMs. However, the assumption of rigid MOF frameworks in molecular simulations limited the accuracy of the data used in the predictions, particularly in predicting molecular diffusivities.

Few-shot class-incremental learning (FSCIL) aims to learn from a sequence of incremental data sessions with a limited number of samples in each class. The main issues it encounters are the risk of forgetting previously learned data when introducing new data classes, as well as not being able to adapt the old model to new data due to limited training samples. Existing state-of-the-art solutions normally utilize pre-trained models with fixed backbone parameters to avoid forgetting old knowledge.

To clarify the roles and mechanisms of adipokine chemerin in exercise-induced bone improvements in type 2 diabetes mellitus (DM) mice and mice fed on high fat diet (HFD). DM mice were established by HFD + streptozotocin injection, exogenous chemerin was supplemented prior to running, and found that exogenous chemerin reversed 6-week exercise-induced improvements in cancellous bone parameters in DM mice. While adipose-specific chemerin knockout improved microstructure and mass of cancellous bone in HFD mice and further increased exercise-induced bone improvements, accompanied with promoted osteogenesis and inhibited osteoclasis represented as the changes of RANKL, M-CSF, Runx2, Osterix, OPG, ALP and CTSK.

The brain of patients with Parkinson's disease (PD) was characterized by increased phosphorylation and oligomerization of α-synuclein (α-syn) and altered activity of enzymes regulating α-syn phosphorylation and oligomerization. Whether increased α-syn phosphorylation and oligomerization as well as related enzyme changes can be detected in the plasma of PD patients remains unclear. Here, we showed that human α-syn proteins incubated in PD plasma formed more oligomerized α-syn (O-α-syn) and phosphorylated α-syn (pS-α-syn) than those in healthy control (HC) plasma.

Background And Objectives: In the current global health landscape, there is an increasing demand for rapid and accurate assessment of mental states. Traditional assessment methods typically rely on face-to-face interactions, which are not only time-consuming but also highly subjective. Addressing this issue, this study aims to develop a client-server-based, non-contact multimodal emotion and behavior recognition system to enhance the efficiency and accuracy of mental state assessments.

The Trans Golgi Network (TGN)/endosomal system is a sorting center for cargo brought via the anterograde secretory pathway and the endocytic pathway that internalizes material from the plasma membrane. As many of the cargo that transit this central trafficking hub are components of key homeostatic signaling pathways, TGN/endosomes define a critical signaling hub for cellular growth control. A particularly interesting yet incompletely understood aspect of regulation of TGN/endosome function is control of this system by two families of lipid exchange/lipid transfer proteins.

In the present study, the mechanism, origin of chemoselectivity, and substituent effects of the phosphine-catalyzed ring-opening reaction of cyclopropyl ketone have been investigated using the DFT method. Multiple pathways, including the formation of hydrofluorenone, the Cloke-Wilson product, and cyclopenta-fused product, were studied and compared. The computational results show that the pathway for the formation of hydrofluorenone is the most favorable one, which involves four processes: nucleophilic substitution to open the three-membered ring, an intramolecular Michael addition for the formation of an enolate intermediate, an intramolecular [1,5]-proton transfer to give ylide, and an intramolecular Wittig reaction to deliver the final product.

HO photosynthesis represents an appealing approach for sustainable and decentralized HO production. Unfortunately, current reactions are mostly carried out in laboratory-scale single-phase batch reactors, which have a limited HO production rate (<100 μmol h) and cannot operate in an uninterrupted manner. Herein, we propose continuous HO photosynthesis and extraction in a biphasic fluid system.
