Sustained Release of HIF-2α Inhibitors Using Biodegradable Porous Silicon Carriers for Enhanced Immunogenic Cell Death of Malignant Merkel Cell Carcinoma.

Merkel cell carcinoma (MCC) is a rare but aggressive neuroendocrine skin cancer with limited treatment options, often associated with Merkel cell polyomavirus (MCPyV) and marked by hypoxic tumor microenvironments that promote resistance to therapies. Belzutifan, an FDA-approved hypoxia-inducible factor-2α (HIF-2α) inhibitor, has shown promise in inhibiting tumor growth; however, its clinical efficacy is hindered by its low solubility, rapid clearance, and limited bioavailability. In this study, we present a strategy using porous silicon (pSi) microparticles and nanoparticles as carriers for the sustained delivery of benzoate to MCC cells.

Systematic ocular phenotyping of 8,707 knockout mouse lines identifies genes associated with abnormal corneal phenotypes.

Purpose: Corneal dysmorphologies (CDs) are typically classified as either regressive degenerative corneal dystrophies (CDtrs) or defective growth and differentiation-driven corneal dysplasias (CDyps). Both eye disorders have multifactorial etiologies. While previous work has elucidated many aspects of CDs, such as presenting symptoms, epidemiology, and pathophysiology, the genetic mechanisms remain incompletely understood.

Mouse models for metabolic health research: molecular mechanism of exercise effects on health improvement through adipose tissue remodelling.

Exercise provides health benefits to multiple metabolic tissues through complex biological pathways and interactions between organs. However, investigating these complex mechanisms in humans is still limited, making mouse models extremely useful for exploring exercise-induced changes in whole-body metabolism and health. In this review, we focus on gaining a broader understanding of the metabolic phenotypes and molecular mechanisms induced by exercise in mouse models.

In this retrospective study, 68 patients were included, with 34 receiving isotonic saline injections and 34 undergoing Extracorporeal Shock Wave Therapy (ESWT) as a control.

Adenylate kinase 5 deficiency impairs epididymal white adipose tissue homeostasis and decreases fat mass.

Importance: The brain and adipose tissue interact metabolically, and if there is a problem with the energy metabolism of the brain, it cannot maintain the energy balance with the adipose tissue. Therefore, when adenylate kinase 5 (), which regulates energy metabolism in the brain, is knocked out, problems with lipid metabolism may occur.

Objective: We aimed to elucidate the metabolic function and phenotype of , a gene with an unknown function in metabolism.

Wheeze and Crackle Discrimination Algorithm in Pneumonia Respiratory Signals.

A new pneumonia detection method is proposed to provide both pneumonia detection in respiratory sound signals and wheeze and crackle discrimination when pneumonia episodes are detected. In the proposed method, two-step hierarchy, classifying pneumonia in the first step and discriminating wheezing and crackling in the second step, is considered; the conventional pneumonia detection method is modified to improve pneumonia detection performance, while wheezing and crackling discrimination functionality is added to facilitate the application of appropriate remedies for each case. We used resampling techniques to address the imbalance in the ICBHI pneumonia dataset.

Characteristic visual phenotypes in Korean wild mice (KWM/Hym).

Background: In the last few decades, numerous efforts have been made to develop a better mouse model to overcome the current limitations of laboratory inbred mouse models such as have a weaker and simpler immune status. As part of these efforts, in Korea, the Hallym university medical genetics research team has been developing a new inbred strain of Korean wild mouse KWM/Hym. It was suggested that this strain, which is derived from wild mice, might be useful for genetic research and may become a valuable tool for overcoming some limitations seen in inbred mice that are currently used in the laboratory.

Cobalt-Based ZIF Composite Membranes: In Situ Defect Engineering for Enhanced Water Stability and Gas Separation.

Porous coordination polymers with excellent molecular sieving ability, high dispersibility, and good compatibility with engineered polymer matrices hold promise for various industrial applications, such as gas separation and battery separators. Here, an in situ defect engineering approach is proposed for highly processable cobalt (Co)-based zeolitic imidazolate frameworks (ZIFs) with enhanced molecular sieving ability and water stability. By varying alkylamine (AA) modulators, the pore structures and textural properties of ZIFs can be fine-tuned.

Efficacy of combining aspirin with hydroxychloroquine in pregnancies at high risk for pre-eclampsia: a prospective, multicentre, open-label, single-arm clinical trial, investigator-initiated study (HUGS study).

Introduction: The use of hydroxychloroquine (HCQ) during pregnancies complicated by systemic lupus erythematosus or refractory antiphospholipid antibody syndrome has demonstrated a significant ability to prevent pre-eclampsia (PE). As such, the potential for the administration of HCQ to prevent PE in other high-risk pregnancies is an important clinical research agenda among maternal and fetal medicine specialists. Mechanistically, the anti-inflammatory and immunomodulatory effects of HCQ can offer vascular protection and inhibit the placental dysfunction-associated thrombotic changes underlying the pathophysiology of PE, fetal growth restriction (FGR) and fetal death in utero (FDIU).

Self-Assembled Peptide-Derived Proteolysis-Targeting Chimera (PROTAC) Nanoparticles for Tumor-Targeted and Durable PD-L1 Degradation in Cancer Immunotherapy.

Proteolysis-targeting chimeras (PROTACs) are a promising technique for the specific and durable degradation of cancer-related proteins via the ubiquitin-proteasome system in cancer treatment. However, the therapeutic efficacy of PROTACs is restricted due to their hydrophobicity, poor cell permeability and insufficient tumor-targeting ability. Herein, we develop the self-assembled peptide-derived PROTAC nanoparticles (PT-NPs) for precise and durable programmed death-ligand 1 (PD-L1) degradation in targeted tumors.

Elimination of olfactory sensory neurons by zinc sulfate inoculation prevents SARS-CoV-2 infection of the brain in K18-hACE2 transgenic mice.

Lactate utilization in Lace1 knockout mice promotes browning of inguinal white adipose tissue.

Recent studies have focused on identifying novel genes involved in the browning process of inguinal white adipose tissue (iWAT). In this context, we propose that the mitochondrial ATPase gene lactation elevated 1 (Lace1) utilizes lactate to regulate the browning capacity of iWAT, specifically in response to challenge with CL-316,243 (CL), a beta3-adrenergic receptor (β3-AR) agonist. The mice were injected with CL over a span of 3 days and exposed to cold temperatures (4-6 °C) for 1 week.

MicBall800-coated metal clip as a novel fluorescent marker for image-guided laparoscopic surgery.

Accurate tumor localization is crucial for the success of minimally invasive surgery, as it minimizes the resection of normal tissues surrounding tumors. Traditional methods for marking gastrointestinal (GI) tumors, such as ink tattooing, intraoperative gastroscopy or colonoscopy, and placement of metal clips, have major drawbacks in their application in laparoscopic surgery. Therefore, the development of safe and easy-to-operate marking methods for accurate and real-time detection of GI tumors during laparoscopic surgery remains an ongoing challenge.
