GATA2 participates in protection against hypoxia-induced pulmonary vascular remodeling.

The vascular endothelium is vital for cardio-pulmonary homeostasis and, thus, plays a crucial role in preventing life-threatening lung diseases. The transcription factor GATA2 is essential for hematopoiesis and maintaining vascular integrity. Heterozygous mutations in GATA2 can lead to a primary immunodeficiency syndrome with pulmonary manifestations.

Comparative educational effectiveness of AI generated images and traditional lectures for diagnosing chalazion and sebaceous carcinoma.

Sebaceous carcinoma is difficult to distinguish from chalazion due to their rarity and clinicians' limited experience. This study investigated the potential of AI-generated image training to improve diagnostic skills for these eyelid tumors compared to traditional video lecture-based education. Students from Orthoptics, Optometry, and Vision Research (n = 55) were randomly assigned to either an AI-generated image training group or a traditional video lecture group.

Omega-3 fatty acids mitigate skin damage caused by ultraviolet-B radiation.

Mice fed a diet containing an adequate amount of ω-3 fatty acids (ω-3 Adq) or a deficient diet (ω-3 Def) were irradiated with ultraviolet-B (UV-B) and were measured daily changes in transepidermal water loss (TEWL). TEWL was significantly increased in ω-3 Def mice with repeated UV-B irradiation, but this increase was significantly reduced in ω-3 Adq mice. The epidermal layers revealed thickening of the spinous and basal layers induced by UV-B irradiation in both groups.

Endothelial GATA3 is involved in coagulofibrinolytic homeostasis during endotoxin sepsis.

Sepsis-induced acute lung injury represents a significant threat to human health and is frequently associated with pulmonary thrombosis due to dysregulation of the coagulofibrinolytic system. Plasmin, the major protease that degrades fibrin aggregates, is activated predominantly by tissue-plasminogen activator (tPA), whereas tPA is negatively regulated by plasminogen activator inhibitor (PAI-1). Under septic conditions, the imbalance between coagulation and fibrinolysis results in excessive microthrombosis.

Spatial and temporal tracking of multi-layered cells sheet using reporter gene imaging with human sodium iodide symporter: a preclinical study using a rat model of myocardial infarction.

Purpose: This study aimed to evaluate a novel technique for cell tracking by visualising the activity of the human sodium/iodide symporter (hNIS) after transplantation of hNIS-expressing multilayered cell sheets in a rat model of chronic myocardial infarction.

Methods: Triple-layered cell sheets were generated from mouse embryonic fibroblasts (MEFs) derived from mice overexpressing hNIS (hNIS-Tg). Myocardial infarction was induced by permanent ligation of the left anterior descending coronary artery in F344 athymic rats, and a triple-layered MEFs sheets were transplanted to the infarcted area two weeks after surgery.

Enfortumab Vedotin-Induced Febrile Neutropenia and Hyperglycemia Successfully Treated with Multidisciplinary Treatment Including Continuous Hemodialysis Filtration and Insulin Injection in a Patient with Chemo-Resistant Metastatic Urothelial Carcinoma: A Case Report.

Introduction: Enfortumab vedotin (EV) is an antibody-drug conjugate combining a monoclonal antibody targeting nectin-4 with a highly potent microtubule disrupting agent. EV is expected to be a candidate for the third-line treatment for urothelial carcinoma previously treated with platinum-based chemotherapy and PD-1/PD-L1 inhibitors. Very few cases of patients experienced hyperglycemia of unknown cause.

Ambient Mass Spectrometry and Machine Learning-Based Diagnosis System for Acute Coronary Syndrome.

The purpose of this study is to establish a novel diagnosis system in early acute coronary syndrome (ACS) using probe electrospray ionization-mass spectrometry (PESI-MS) and machine learning (ML) and to validate the diagnostic accuracy. A total of 32 serum samples derived from 16 ACS patients and 16 control patients were analyzed by PESI-MS. The acquired mass spectrum dataset was subsequently analyzed by partial least squares (PLS) regression to find the relationship between the two groups.

[I]CLINDE SPECT as a neuroinflammation imaging approach in a rat model of stroke.

Poststroke neuroinflammation exacerbates disease progression. [C]PK11195-positron emission tomography (PET) imaging has been used to visualize neuroinflammation; however, its short half-life of 20 min limits its clinical use. [I]CLINDE has a longer half-life (13h); therefore, [I]CLINDE-single-photon emission computed tomography (SPECT) imaging is potentially more practical than [C]PK11195-PET imaging in clinical settings.

Fabrication of polycrystalline phosphorus-doped diamond electrodes from red phosphorus.

Polycrystalline phosphorus-doped diamond was fabricated by the quartz-tube-type microwave plasma-assisted chemical vapor deposition method. Significantly, red phosphorus was used as a source of phosphorous, instead of PH. Phosphorus-doped diamond electrodes with hydrogen-terminated and oxygen-terminated surfaces were investigated for the redox reactions of K[Fe(CN)] and [Ru(NH)]Cl.

Mtc6/Ehg2 is a novel endoplasmic reticulum-resident glycoprotein essential for high-pressure tolerance.

Hydrostatic pressure is a common mechanical stressor that modulates metabolism and reduces cell viability. Eukaryotic cells have genetic programs to cope with hydrostatic pressure stress and maintain intracellular homeostasis. However, the mechanism underlying hydrostatic pressure tolerance remains largely unknown.

Corneal Copper Deposition Secondary to Monoclonal Gammopathy in a Patient With Chronic Lymphocytic Leukemia: A Case Report.

Hypercupremia-induced corneal copper deposition secondary to monoclonal gammopathy is rare and shows a characteristic corneal opacity quite different from other causes of hypercupremia, such as Wilson's disease. This report describes a case of corneal copper deposition in a patient with monoclonal gammopathy associated with chronic lymphocytic leukemia. An 84-year-old man with slowly progressive corneal opacity was referred to our hospital.

Perturbed collagen metabolism underlies lymphatic recanalization failure in Gata2 heterozygous deficient mice.

Lymphedema has become a global health issue following the growing number of cancer surgeries. Curative or supportive therapeutics have long been awaited for this refractory condition. Transcription factor GATA2 is crucial in lymphatic development and maintenance, as GATA2 haploinsufficient disease often manifests as lymphedema.

Exogenous l-fucose attenuates neuroinflammation induced by lipopolysaccharide.

α1,6-Fucosyltransferase (Fut8) catalyzes the transfer of fucose to the innermost GlcNAc residue of N-glycan to form core fucosylation. Our previous studies showed that lipopolysaccharide (LPS) treatment highly induced neuroinflammation in Fut8 homozygous KO (Fut8) or heterozygous KO (Fut8) mice, compared with the WT (Fut8) mice. To understand the underlying mechanism, we utilized a sensitive inflammation-monitoring mouse system that contains the human interleukin-6 (hIL6) bacterial artificial chromosome transgene modified with luciferase (Luc) reporter cassette.

Effects of Varied Omega-3 Fatty Acid Supplementation on Postpartum Mental Health and the Association between Prenatal Erythrocyte Omega-3 Fatty Acid Levels and Postpartum Mental Health.

We investigated the postpartum mental health of women who had consumed perilla oil or fish oil containing various omega-3 fatty acids for 12 weeks starting in mid-pregnancy. The association between fatty acids in maternal erythrocytes and mental health risk factors was also examined. Healthy Japanese primiparas in mid-pregnancy (gestational weeks 18-25) were randomly divided into two groups and consumed approximately 2.

Association between dietary carbohydrate intake and risk of type 2 diabetes: a systematic review and meta-analysis of cohort studies.

Background: Previous meta-analyses have assessed the relationship between carbohydrate intake and type 2 diabetes (T2D) risk; however, they included few studies of Asian populations who have a higher carbohydrate intake and lower insulin secretory capacity than non-Asians. Since the publication of the previous meta-analyses, three further studies of Asian populations have been conducted. Based on this background, the present study aimed to perform an updated systematically examine observational studies concerning the link between dietary carbohydrate intake and T2D risk.

A Machine Learning-Based Model to Predict In-Hospital Mortality of Lung Cancer Patients: A Population-Based Study of 523,959 Cases.

Stratify new lung cancer patients based on the risk of in-hospital mortality rate after diagnosis. 522,941 lung cancer cases with available data on the Surveillance, Epidemiology, and End Results (SEER) were analyzed for the predicted probability based on six fundamental variables including age, gender, tumor size, T, N, and AJCC stages. The patients were randomly assigned to the training ( = 115,145) and validation datasets ( = 13,017).

Fatty acid desaturase 2 determines the lipidomic landscape and steroidogenic function of the adrenal gland.

Corticosteroids regulate vital processes, including stress responses, systemic metabolism, and blood pressure. Here, we show that corticosteroid synthesis is related to the polyunsaturated fatty acid (PUFA) content of mitochondrial phospholipids in adrenocortical cells. Inhibition of the rate-limiting enzyme of PUFA synthesis, fatty acid desaturase 2 (FADS2), leads to perturbations in the mitochondrial lipidome and diminishes steroidogenesis.

Meningitis with septic shock resulting from odontogenic infection misdiagnosed as closed-lock in temporomandibular disorder: A case report and literature review.

Rationale: Infections that spread to the pterygomandibular muscle can be misdiagnosed as temporomandibular disorder (TMD) because of the resulting difficulty in opening the mouth. Importantly, infection of the pterygomandibular space can extend to the skull base in the early stages, and a delay in therapeutic intervention can lead to severe complications.

Patient Concerns: A 77-year-old Japanese man with trismus after pulpectomy was referred to our department.

[Perforin gene mutation in middle-age onset hemophagocytic lymphohistiocytosis].

A 54-year-old woman was referred to our hospital for pancytopenia and liver dysfunction, and with no personal or family history of hemophagocytic lymphohistiocytosis (HLH). Although the etiology was unknown, she was diagnosed with HLH. She experienced exacerbation of HLH even after initiating systemic chemotherapy with etoposide, dexamethasone, and cyclosporine.

Anxiety-like behaviors in artificially reared mice is reduced by contact with foster mothers.

Experimental systems using animal models are important for nutritional and pharmacological research on newborns and infants. Accordingly, artificial nursing systems for rodents based exclusively on formula are critical to studying nutrient requirements, chemical safety, and immune system development in newborns and infants while eliminating the influence of mother's milk. Such systems can also be used to study the influence of rearing environment-related factors, including physical contact between newborns and mothers or caregivers.
