Neuronal fatty acid-binding protein enhances autophagy and suppresses amyloid-β pathology in a Drosophila model of Alzheimer's disease.

Fatty acid-binding proteins (FABPs) are small cytoplasmic proteins involved in intracellular lipid transport and bind free fatty acids, cholesterol, and retinoids. FABP3, the major neuronal FABP in the adult brain, is upregulated in the CSF of patients with Alzheimer's disease (AD). However, the precise role of neuronal FABPs in AD pathogenesis remains unclear.

The role of glial and neuronal Eph/ephrin signaling in Drosophila mushroom body development and sleep and circadian behavior.

The Eph receptor, a prototypically large receptor protein tyrosine kinase, interacts with ephrin ligands, forming a bidirectional signaling system that impacts diverse brain functions. Eph receptors and ephrins mediate forward and reverse signaling, affecting neurogenesis, axon guidance, and synaptic signaling. While mammalian studies have emphasized their roles in neurogenesis and synaptic plasticity, the Drosophila counterparts are less studied, especially in glial cells, despite structural similarities.

Investigating the Potential of Perovskite Nanocrystal-Doped Liquid Scintillator: A Feasibility Study.

Liquid scintillators are extensively employed as targets in neutrino experiments and in medical radiography. Perovskite nanocrystals are recognized for their tunable emission spectra and high photoluminescence quantum yields. In this study, we investigated the feasibility of using perovskites as an alternative to fluor, a substance that shifts the wavelengths.

Feasibility Study on the Discrimination of Fluor Concentration in the Liquid Scintillator Using PMT Waveform and Short-Pass Filter.

Neutrinos are difficult to detect because they weakly interact with matter, making their properties least known. The response of the neutrino detector depends on the optical properties of the liquid scintillator (LS). Monitoring any characteristic changes in the LS helps to understand the temporal variation of detector response.

Neuroprotective effects of linear ubiquitin E3 ligase against aging-induced DNA damage and amyloid β neurotoxicity in the brain of Drosophila melanogaster.

E3 ubiquitin ligase, HOIL1-interacting protein (HOIP), forms the linear ubiquitin chain assembly complex (LUBAC) with HOIL and SHANK-associated RH domain interactor and catalyzes linear ubiquitination, directly linking the N- and C-termini of ubiquitin. Recently, several studies have implicated linear ubiquitination in aging and Alzheimer disease (AD). However, little is currently known about the roles of HOIP in brain aging and AD pathology.

Nationwide population-based incidence of cancer among patients with HIV/AIDS in South Korea.

Cancers are the leading cause of death among people living with HIV/AIDS (PLWHA); however, nationwide studies on cancer incidence are limited. We aimed to determine the trends in the incidence rates of AIDS-defining cancers (ADCs) and non-AIDS-defining cancers (NADCs) among Korean PLWHA. Data from the National Health Insurance Sharing Service from 2004 to 2017 were collected.

Prognostic Impact of Peripheral Blood T-Cell Subsets at the Time of Diagnosis on Survival in Patients with Diffuse Large B-Cell Lymphoma.

Introduction: The effects of lymphocyte subtypes, including helper (Th), natural killer (NK), and regulatory (Treg) cells, and other T-cell subtypes on treatment outcomes in diffuse large B-cell lymphoma (DLBCL) patients are not clearly established.

Methods: Among 151 consecutive patients diagnosed with DLBCL, we collected peripheral blood samples at diagnosis from 91 patients who received at least 1 cycle of R-CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone plus rituximab) chemotherapy and analyzed lymphocyte subsets by flow cytometry.

Results: DLBCL patients had a higher proportion of CD4+CD25+ Treg (p < 0.

Thyroid cancer after hysterectomy and oophorectomy: a nationwide cohort study.

Objective: Little is known about the role of estrogen in thyroid cancer development. We aimed to evaluate the association between hysterectomy or bilateral salpingo-oophorectomy (BSO) and the risk of subsequent thyroid cancer.

Design: A nationwide cohort study.

Association between Serum Free Thyroxine and Anemia in Euthyroid Adults: A Nationwide Study.

Background: Studies on the relationship between thyroid function and anemia in the euthyroid range are scarce. We aimed to evaluate the association between anemia and serum free thyroxine (fT4) and thyrotropin (TSH) in euthyroid adults.

Methods: Data on 5,352 participants aged ≥19 years were obtained from the Korea National Health and Nutrition Examination Survey VI (2013 to 2015).

The Relationship between Thyroid Function and Different Obesity Phenotypes in Korean Euthyroid Adults.

Background: Thyroid disease and metabolic syndrome are both associated with cardiovascular disease. The aim of this study was to investigate the correlation between thyroid hormones and obesity sub-phenotypes using nationwide data from Korea, a country known to be iodine replete.

Methods: This study was based on data obtained from the sixth Korea National Health and Nutrition Examination Survey, administered from 2013 to 2015.

A study on the prevention of salmonella infection by using the aggregation characteristics of lactic Acid bacteria.

Salmonella is one of the major pathogenic bacteria that cause food poisoning. This study investigated whether heat-killed as well as live Lactobacillus protects host animal against Salmonella infection. Live and heat-killed Lactobacillusacidophilus was administered orally to Sprague-Dawley rats for 2 weeks before the rats were inoculated with Salmonella.

Surface EMG during the Push-up plus Exercise on a Stable Support or Swiss Ball: Scapular Stabilizer Muscle Exercise.

[Purpose] Scapular stabilizer strengthening exercise is crucial for shoulder rehabilitation. The purpose of this study was to compare two types of push-up plus exercises, on a stable and unstable bases of support, using surface electromyography (EMG), to suggest an effective shoulder rehabilitation program. [Subjects and Methods] Ten healthy men volunteered for this study.

Trichostatin A promotes the development of bovine somatic cell nuclear transfer embryos.

We studied the effects of trichostatin A (TSA), a histone deacetylase inhibitor, on the development of bovine somatic cell nuclear transfer (SCNT) embryos by investigating (1) the optimal concentration and treatment time of TSA for development of bovine SCNT embryos, (2) the status of histone acetylation in TSA-treated and control SCNT embryos and (3) the expression of histone acetylation- and deacetylation-related genes in TSA-treated and control SCNT embryos. We observed that 50 nM TSA-treatment for 20 h following fusion resulted in more efficient in vitro development of bovine SCNT embryos to the blastocyst stage. In regard to histone H4K5 acetylation, half of the control SCNT embryos faintly displayed histone H4K5 signals 30 min after electrofusion, while most of the TSA-treated SCNT embryos displayed histone H4K5 signals within 30 min after electrofusion.

Production of recombinant human von Willebrand factor in the milk of transgenic pigs.

Von Willebrand factor (vWF), a large multimeric glycoprotein present in blood plasma, is a blood protein of the coagulation system. It is defective in von Willebrand disease and is involved in a large number of other diseases, including thrombotic thrombocytopenic purpura-hemolytic uremic syndrome and heyde's syndrome. We have developed a line of transgenic swine harboring recombinant human von Willebrand factor (rhvWF) cDNA through microinjection of fertilized one-cell pig zygotes.

Recombinant human erythropoietin produced in milk of transgenic pigs.

We have developed a line of transgenic swine harboring recombinant human erythropoietin through microinjection into fertilized one cell pig zygotes. Milk from generations F1 and F2 transgenic females was analyzed, and hEPO was detected in milk from all lactating females at concentrations of approximately 877.9+/-92.
