Hyperlipidemia represents a major global health concern, closely linked to cardiovascular disease (CVD) and metabolic syndrome. Effective regulation of blood lipid and cholesterol (CHO) is essential for preventing and managing this condition. Korean red ginseng (KRG), a traditional medicinal plant, exhibits diverse pharmacological properties, including antihyperlipidemic, immune-enhancing, anti-fatigue, and antistress effects.

Background: Metabolic syndrome (MetS) is a complex health concern and the incidence of MetS is rising, even among the general population, necessitating effective identification and management strategies. This study aimed to determine if a predictive model using variables from fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) and machine learning (ML) could enhance the prediction of MetS.

Methods: We retrospectively reviewed the medical records of 1,250 adults who underwent FDG PET/CT for cancer screening between 2014 and 2020.

IgG-based therapeutic antibodies are increasingly adopted for diverse human diseases, such as cancer and autoimmune disorders displaying remarkable therapeutic performance. A key factor in their success lies in the extended half-life of IgG molecules, which is regulated by the pH-dependent interaction between IgG and neonatal Fc receptor (FcRn). This interaction prevents lysosomal degradation of IgG.

Protein phosphatase 2A-B56 (PP2A-B56) is a key regulator of mitosis, playing an essential role in maintaining chromosomal stability and ensuring the fidelity of cell division. As a component of the PP2A holoenzyme, the B56 regulatory subunit confers substrate specificity, primarily through interactions with the conserved LxxIxE motif on target proteins. This review highlights the molecular mechanisms by which PP2A-B56 regulates key processes in cell division, including chromosome cohesion and condensation, kinetochore-microtubule attachment, spindle assembly checkpoint silencing, and activation of the anaphase-promoting complex/cyclosome.

Osteoarthritis (OAI) and osteoarthrosis (OAO) are subsets of degenerative joint diseases affecting the temporomandibular joint (TMJ), distinguished by the presence of joint pain. However, clinical diagnosis based on pain alone is challenging. This study aimed to differentiate OAI from OAO using imaging modalities, including single-photon emission computed tomography (SPECT-CT) and magnetic resonance imaging (MRI).

This study explores Malaysian parents' perspectives on speech-language pathology (SLP) telepractice services during the COVID-19 lockdown. SLP services for families living in rural areas of Malaysia can be challenging, due to travel issues associated with distance, transportation costs, scheduling conflicts, and for patients with restricted physical mobility. To investigate the efficacy of SLP services in Malaysia during the COVID-19 lockdown, 70 parents' preferences and perspectives were explored via a survey of demographics, service engagement, and views on telepractice.

This study aims to investigate the modulatory effects of focused ultrasound (FUS) on neuronal activity at the single-cell level, using whole-cell patch clamp recordings in hippocampal slices.A self-focused acoustic transducer (SFAT) was designed and fabricated on a 127m-thick translucent lead zirconate titanate substrate to allow infrared light transmission for visualizing neurons during patch clamp experiments. The SFAT operates at 18.

Healthier soils are often assumed to retain function better under climate stress. However, links between common soil health indicators and soil functional resilience to stress are elusive. Our goal was to link soil health status with stress response by quantifying the multifunctional carbon (C) and nitrogen (N) cycling response of soils under different management (forest, conventional, or organic) to drought or combined drought and heat stress.

The limitations of traditional von Neumann architectures have driven interest in organic mixed ionic-electronic conductors (OMIECs) for integrating memory and computation. Organic electrochemical synaptic transistors (OESTs) are particularly promising for emulating biological synaptic behaviors because they offer low power consumption, flexibility, and scalability. One-shot integrable electropolymerization (OSIEP) has emerged as a promising approach for fabricating OESTs owing to its simplicity and integrative capabilities.

Differences exist between Infectious Diseases Society of America guidance and European Society of Clinical Microbiology and Infectious Diseases guidelines on treating pneumonia caused by carbapenem-resistant (CRAB). This study compared the outcomes of colistin-based and high-dose ampicillin/sulbactam-based combination therapies in patients with CRAB nosocomial pneumonia. A retrospective cohort study was conducted at a university-affiliated hospital in South Korea.

Etoposide, an anticancer drug that inhibits topoisomerase II, is commonly used in combination chemotherapy. However, the impact of O-GlcNAcylation regulation on etoposide's anticancer effects has rarely been investigated. This study evaluated the effect of etoposide on cellular O-GlcNAcylation and whether modulating this process enhances etoposide-induced apoptosis.

Abscisic acid (ABA) is a key phytohormone that regulates multiple biological processes in plants, including seed germination, seedling growth, and abiotic stress response. ABA enhances drought tolerance by promoting stomatal closure, thereby improving crop productivity under unfavorable stress conditions. Extensive research efforts have focused on understanding ABA signaling more clearly for its potential application in agriculture.

Background: Berberine has therapeutic potential in central nervous system disorders, however, few studies have investigated the effect of berberine on axonal regeneration in PNS injury models. Thus, this study aims to assess the effects of berberine on axonal regeneration in a peroneal nerve transection rat model.

Methods: Sprague-Dawley rats were divided into two groups: group B, berberine (20 mg/kg) intraperitoneal injection after peroneal nerve transection; and group C, normal saline injection as a control.

Until now, Hippo pathway-mediated nucleocytoplasmic translocation has been considered the primary mechanism by which yes-associated protein (YAP) and transcriptional co-activator with PDZ-binding motif (TAZ) transcriptional coactivators regulate cell proliferation and differentiation via transcriptional enhanced associate domain (TEAD)-mediated target gene expression. In this study, however, we found that TAZ, but not YAP, is associated with the Golgi apparatus in macrophages activated via Toll-like receptor ligands during the resolution phase of inflammation. Golgi-associated TAZ enhanced vesicle trafficking and secretion of proinflammatory cytokines in M1 macrophage independent of the Hippo pathway.

Electron-transporting transparent conducting oxides (TCOs) are a commercial reality, however, hole-transporting counterparts are far more challenging because of limited material design. Here, we propose a strategy for enhancing the hole conductivity without deteriorating the band gap () and workfunction () by Cu incorporation in a strongly correlated NiWO insulator. The optimal Cu-doped NiWO (CuNiWO) exhibits a resistivity reduction of ∼10 times NiWO as well as band-like charge transport with the hole mobility approaching 7 cm V s at 200 K, a deep of 5.
