Background: Ankle fractures are among the most common types of fractures in the orthopaedic field, and the Lauge-Hansen classification is commonly used to categorize rotational ankle fractures. This study evaluated and compared the clinical and radiological outcomes of surgically treated supination external rotation (SER) and pronation external rotation (PER) injuries of grades III or IV.
Methods: We retrospectively reviewed and enrolled 104 patients who underwent open reduction and internal fixation for SER or PER injuries classified as Grades III or IV between January 2016 and December 2021, all performed at a single center.

A facultative anaerobic, Gram-stain-negative, non-motile, rod-shaped bacterial strain AGMB14963 was isolated from the feces of a dairy cow. A 16S rRNA gene sequence-based phylogenetic analysis revealed that strain AGMB14963 belongs to the genus Gallibacterium, with Gallibacterium salpingitidis F150 being the closest species (95.8% 16S rRNA gene sequence similarity).

Developing a portable yet affordable method for the discrimination of chemical substances with good sensitivity and selectivity is essential for on-site visual detection of unknown substances. Herein, we propose an optofluidic paper-based analytical device (PAD) that consists of a macromolecule-driven flow (MDF) gate and photonic crystal (PhC) coding units, enabling portable and scalable detection and discrimination of various organic chemical, mimicking the olfactory system. The MDF gate is designed for precise flow control of liquid analytes, which depends on intermolecular interactions between the polymer at the MDF gate and the liquid analytes.

Background: The phase 3 open-label KEYNOTE-426 study demonstrated that first-line pembrolizumab plus axitinib improved overall survival (OS) and progression-free survival (PFS) versus sunitinib for metastatic renal cell carcinoma (mRCC) in a global population. This subgroup analysis investigated the efficacy and safety of pembrolizumab-axitinib versus sunitinib in patients enrolled in KEYNOTE-426 in East Asia (Japan, South Korea, and Taiwan).
Methods: Adults with clear cell mRCC were randomly assigned 1:1 to receive intravenous pembrolizumab 200 mg every 3 weeks with oral axitinib 5 mg twice daily or oral sunitinib 50 mg once daily (4 weeks on/2 weeks off).

Copper-tantalate, CuTaO (CTO), shows significant promise as an efficient photocathode for multi-carbon compounds (C) production through photoelectrochemical (PEC) CO reduction, owing to its suitable energy bands and catalytic surface. However, synthesizing CTO poses a significant challenge due to its metastable nature and thermal instability. In this study, this challenge is addressed by employing a flux-mediated synthesis technique using a sodium-based flux to create sodium-doped CTO (Na-CTO) thin films, providing enhanced nucleation and stabilization for the CTO phase.

Understanding the reversible transformation between two isomeric states of organic molecules under external stimulation is essential for advancing single-molecule device development. Photochromic diarylethene (DAE) derivatives are promising candidates for single molecular switching elements. This study investigates the single-molecule reactions of the closed-form isomer of a DAE derivative on Cu(111) using scanning tunneling microscopy (STM).

ETV2/ER71, an ETS (E-twenty six) transcription factor, is critical for hematopoiesis and vascular development. However, research about the molecular mechanisms behind ETV2-mediated gene transcription is limited. Herein, we demonstrate that ETV2 and KDM4A, an H3K9 demethylase, regulate hematopoietic and endothelial genes.

Hypercholesterolemia is a risk factor of coronary heart disease and cholesterol-lowering probiotics are seen as alternative to drugs for the management of this condition. In the present study, we evaluated the cholesterol-lowering activity of KS6I1 in high-cholesterol diet-induced hypercholesterolemic mice. The mice were fed with high-cholesterol diet (HCD) and were divided into three groups: HCD group, KS6I1 group (fed with HCD + 200 μl of 10 CFU/ml KS6I1), and L.

Combination therapy with checkpoint inhibitors blocks inhibitory immune cell signaling and improves clinical responses to anticancer treatments. However, continued development of innovative and controllable delivery systems for immune-stimulating agents is necessary to optimize clinical responses. Herein, we engineered to deliver recombinant granulocyte macrophage colony stimulating factor (GM-CSF) in a controllable manner for combination treatment with a programmed death-ligand 1 (PD-L1) inhibitor.

Background: Interleukin-6 (IL-6) plays a central role in sepsis-induced cytokine storm involving immune hyperactivation and early neutrophil activation. Programmed death protein-1 (PD-1) is associated with sepsis-induced immunosuppression and lymphocyte apoptosis. However, the effects of simultaneous blockade of IL-6 and PD-1 in a murine sepsis model are not well understood.

The issue of whether a salient stimulus in the visual field captures attention in a stimulus-driven manner has been debated for several decades. The attentional window account proposed to resolve this issue by claiming that a salient stimulus captures attention and interferes with target processing only when an attentional window is set wide enough to encompass both the target and the salient distractor. By contrast, when a small attentional window is serially shifted among individual stimuli to find a target, no capture is found.

Proton pump inhibitors (PPIs), metabolized by cytochrome P450 (P450) enzymes, are widely used to inhibit gastric acid secretion. This study investigated CYP116B46, a self-sufficient monooxygenase with a reductase domain, to elucidate its interaction with ilaprazole, a PPI. Binding assays and docking simulations indicate that CYP116B46 serves as a suitable model for studying PPI metabolism.

Spermatozoa must undergo a complex maturation process within the female genital tract known as capacitation. This process entails the phosphorylation or dephosphorylation of various proteins, and multiple signaling pathways are recognized to play a role. The present study aims to identify alterations in the expression of proteins related to the phosphatidylinositol-3 kinase (PI3K)/protein kinase B (AKT) signaling pathway and assess sperm functions during capacitation.
