Dehalogenative deuteration of alkyl and aryl bromides by thiyl radical catalysis under visible-light irradiation.

Herein, we report a mild and practical method for the deuteration of alkyl and aryl bromides by a thiyl radical catalyst and halogen-atom transfer (XAT) using disulfides and silanes under visible-light irradiation. In this study, various organic bromides such as 1°, 2°, and 3°-alkyl bromides and aryl bromides were converted to deuterated products in good to excellent yields and D-incorporation.

Particulate matter 10 induces oxidative stress and apoptosis in rhesus macaques skin fibroblast.

Background: Particulate matter (PM) is a major air pollutant that affects human health worldwide. PM can pass through the skin barrier, thus causing skin diseases such as heat rash, allergic reaction, infection, or inflammation. However, only a few studies have been conducted on the cytotoxic effects of PM exposure on large-scale animals.

Association of Blood Pressure With Cardio-Renal Events and Mortality in Type 2 DM: A National Health Insurance Database.

Context: The relationship of blood pressure (BP) with cardio-renal events and all-cause mortality in type 2 diabetes mellitus (T2DM) is still controversial.

Objective: To investigate the optimal BP target in Korean individuals with T2DM.

Methods: Using the Korean National Health Insurance System database, data of individuals with T2DM who underwent regular health checks from January 1, 2007, to December 31, 2007, were extracted (N = 1 800 073).

Association between the Diabetes Drug Cost and Cardiovascular Events and Death in Korea: A National Health Insurance Service Database Analysis.

Backgruound: This study aimed to investigate the long-term effects of diabetes drug costs on cardiovascular (CV) events and death.

Methods: This retrospective observational study used data from 2009 to 2018 from the National Health Insurance in Korea. Among the patients with type 2 diabetes, those taking antidiabetic drugs and who did not have CV events until 2009 were included.

IL-6 and IL-10 Levels, Rather Than Viral Load and Neutralizing Antibody Titers, Determine the Fate of Patients With Severe Fever With Thrombocytopenia Syndrome Virus Infection in South Korea.

Severe fever with thrombocytopenia syndrome (SFTS) is a new tick-borne viral disease, and most SFTS virus (SFTSV) infections occur bites from the tick ; however, SFTSV transmission can also occur through close contact with an infected patient. SFTS is characterized by acute high fever, thrombocytopenia, leukopenia, elevated serum hepatic enzyme levels, gastrointestinal symptoms, and multiorgan failure and has a 16.2 to 30% mortality rate.

Anti-inflammatory effect of bee venom in phthalic anhydride-induced atopic dermatitis animal model.

Globally, many people have been affected with atopic dermatitis (AD), a chronic inflammatory skin disease. AD is associated with multiple factors such as genetic, inflammatory, and immune factors. Bee venom (BV) is now widely used for the treatment of several inflammatory diseases.

The effect of using games in teaching conservation.

Games are an increasingly popular approach for conservation teaching. However, we know little about the effectiveness of the games on students' experiences and knowledge acquisition. Many current games are supplemental games (SG) that have no meaningful interaction with the subject matter.

A quasi-solid-state rechargeable lithium-oxygen battery based on a gel polymer electrolyte with an ionic liquid.

A quasi-solid-state lithium-oxygen battery constructed using a gel polymer electrolyte with an ionic liquid is proposed. The battery architecture incorporates a design feature that can be easily scaled up in size for use in large systems. The feasibility study demonstrates that the battery operates successfully for repeated discharge-charge cycles.

Sequential treatment of HPV E6 and E7-expressing TC-1 cells with bortezomib and celecoxib promotes apoptosis through p-p38 MAPK-mediated downregulation of cyclin D1 and CDK2.

Interruption of the cell cycle is accompanied by changes in several related molecules that result in the activation of apoptosis. The present study was performed to verify the apoptotic effects of sequential treatment with bortezomib and celecoxib in TC-1 cells expressing the human papillomavirus (HPV) E6 and E7 proteins. In TC-1 cells sequentially treated with bortezomib and celecoxib, apoptosis was induced through decreased expression of signal transducer and activator of transcription-3 (STAT3), cyclin D1 and cyclin-dependent kinase (CDK) 2, which are major regulators of the G0/G1 cell cycle checkpoint.

Promoting Li2O2 oxidation by an La(1.7)Ca(0.3)Ni(0.75)Cu(0.25)O4 layered perovskite in lithium-oxygen batteries.

We demonstrate for the first time that La(1.7)Ca(0.3)Ni(0.

Cancer cells containing nanoscale chemotherapeutic drugs generate antiovarian cancer-specific CD4+ T cells in peritoneal space.

Owing to the poor prognosis of patients with ovarian cancer, new treatment strategies immediately need to be developed. Although several immunotherapeutic approaches have been examined for the treatment of advanced stage ovarian cancer, their implementation in clinical practice remains low. We previously showed doxorubicin-treated murine ovarian cancer cells [murine ovarian surface epithelial cells (MOSECs)] are able to deliver drug to adjacent cells in vivo to eradicate tumor cells.
