Machine learning potentials (MLPs) offer efficient and accurate material simulations, but constructing the reference ab initio database remains a significant challenge, particularly for catalyst-adsorbate systems. Training an MLP with a small data set can lead to overfitting, thus limiting its practical applications. This study explores the feasibility of developing computationally cost-effective and accurate MLPs for catalyst-adsorbate systems with a limited number of ab initio references by leveraging a transfer learning strategy from subsets of a comprehensive public database.

A 55-year-old woman with non-small cell lung carcinoma complained of epigastric pain, bloating, anorexia and postprandial nausea and vomiting over a five-year period. An upper gastrointestinal pan-glucosamine contrast examination revealed a distinctive large, hook-shaped, ptotic gastric lumen with normal motility. The contrast agent demonstrated an abnormal round-trip flow anterior to the spine at the duodenal level, with pooling and gradual passage through this region in strands after prolonged retention.

Multidrug-resistant pathogens pose a major threat to human health, necessitating the identification of new drug targets and lead compounds that are not susceptible to cross-resistance. This study demonstrates that novel reverse thia analogs of the phosphonohydroxamic acid antibiotic fosmidomycin inhibit 1-deoxy-d-xylulose 5-phosphate reductoisomerase (DXR), an essential enzyme for , , and that is absent in humans. Some novel analogs with large α-phenyl substituents exhibited strong inhibition across these three DXR orthologues, surpassing the inhibitory activity of fosmidomycin.

We proposed a novel ligand for the interaction with human serum albumin (HSA) to extend the blood half-life of small molecular weight therapeutics. The ligand features an alkyl chain and an activated disulfide to allow binding to the hydrophobic pockets of HSA and the formation of disulfide to Cys34 of HSA, thereby minimizing the initial renal clearance. The dual nature of the ligand-HSA bonding was expected to give the ligand long blood retention.

Inhibiting phosphofructokinase-1 (PFK1) is a promising approach for treating lactic acidosis and mitochondrial dysfunction by activating oxidative phosphorylation. Tryptolinamide (TLAM) has been shown as a PFK1 inhibitor, but its complex stereochemistry, with 16 possible isomers complicates further development. We conducted an asymmetric synthesis, determined the absolute configurations, and evaluated the PFK1 inhibitory activity of the TLAM isomers.

Introduction: Tau protein plays a pivotal role in the pathogenesis of Alzheimer's disease (AD) and in regulating neuronal excitability. Among tau-coding microtubule associated protein tau () gene mutations, the A152T mutation is reported to increase the risk of AD and neuronal excitability in mouse models.
Methods: To investigate the effects of gene expression and its mutations on neuronal activity in human neurons, we employed genome editing technology to introduce the A152T or P301S mutations into induced pluripotent stem cells (iPSCs).

Measuring whole-brain distributed functional activity is an important unmet need in neuroscience, requiring high temporal resolution and cellular specificity across large volumes. Functional optoacoustic neuro-tomography (FONT) with genetically encoded calcium ion indicators is a promising approach towards this goal. However, it has not yet been applied in the near-infrared (NIR) range that provides deep penetration and low vascular background optimal for neuroimaging.

Treatment with an inhibitor of glucose use via glucose transporters (GLUT) has been shown to attenuate experimental abdominal aortic aneurysm (AAA) development in mice. Vascular smooth muscle cell (VSMC) signaling seems to be essential for angiotensin II (Ang II)-induced AAA in mice. Accordingly, we have tested a hypothesis that VSMC silencing of the major GLUT, GLUT1, prevents AAA development and rupture in mice treated with Ang II plus β-aminopropionitrile.

In this study, we explore the potential of the difluoro(trifluoromethoxy)methyl group, CF-O-CF, an underexplored but promising structural analog of the trifluoromethoxy group (OCF). This moiety offers unique electronic properties and enhanced chemical stability due to its multiple C-F bonds, along with the added advantage of C-O bond cleavage, making it an attractive option in fluorine chemistry. We have succeeded in synthesizing difluoro(trifluoromethoxy)methyl compounds radical amino- and hydroxy-trifluoromethoxylations of β,β-difluorostyrenes.

Despite the evident demand and promising potential of disulfide-functionalized amino acids and peptides in linker chemistry and peptide drug discovery, those disulfurated specifically at the α-position constitute a unique yet rather highly underexplored chemical space. In this study, we have developed a method for preparing -linked amino acid/peptide derivatives through a base-catalyzed disulfuration reaction of azlactones, followed by the ring-opening functionalization. The disulfuration reaction proceeds under mild conditions, yielding disulfurated azlactones in excellent yields across a variety of -dithiophthalimides and diverse azlactones derived from various amino acids and peptides.

Recent discussions in epidemiology have emphasised the need to estimate the heterogeneous effects of risk factors across the distribution of health outcomes for better aetiological understanding of the determinants of population health. We propose using quantile regression-based decomposition to expand the empirical discussion on population health intervention strategies for health equity by incorporating population homogeneity/heterogeneity in the risk-outcome association. We theorised that the 'proportionate universalism' approach presumes population homogeneity in the risk-outcome association with varying risk intensities, which decomposition analysis shows as the 'covariates part' between groups.

Type I interferons (IFNs) are immunostimulatory molecules that can activate the innate and adaptive immune systems. In cases of immune dysfunction, prolonged activation of the type I IFN pathway has been correlated with kidney tissue damage in a wide range of kidney disorders, such as lupus nephritis (LN) and focal segmental glomerulosclerosis (FSGS). Genetic mutations, such as risk variants in conjunction with elevated type I IFN expression, are also associated with higher rates of chronic kidney disease in patients with LN and collapsing FSGS.
