The cell-type continuous electromagnetic radiation system is a demonstration device capable of generating high-power millimeter electromagnetic waves of a specific wavelength and observing their effects on living *** irradiates a biological sample placed in a 30×30×50 cm^(3)cell with electromagnetic waves in the 3.15-mm-wavelength region(with an output of≥1 W)and analyzes the temperature change of the sample.A vacuum electronic device-based coupled-cavity backward-wave oscillator converts the electron energy of the electron beam into radiofrequency(RF)energy and radiates it to the target through an antenna,increasing the temperature through the absorption of RF energy in the *** system causes pain and ultimately reduces combat power.A cell-type continuous electromagnetic radiation system consisting of four parts—an electromagnetic-wave generator,a highvoltage power supply,a test cell,and a system controller—generates an RF signal of≥1 W in a continuous waveform at a 95-GHz center frequency,as well as a chemical solution with a dielectric constant similar to that of the skin of a living *** increase of 5°C lasting approximately 10 s was confirmed through an experiment.

目前．韩国正在考虑把地下水用作空间供热和制冷的热源。本项研究评价了韩国266个国家地下水监测站的地下水温度数据。地下水温度的空间分布主要受地理纬度、气温和局部地形高程的影响。地下水温度的分布模式与环境空气温度的分布模式非常类似。地下水温度的年变化可以分为4种主要模式：P型（周期变化）代表地下水温度的年周期变化，大多数浅层地下水的温度变化都属于P型（62．5％）；F型指地下水的温度几乎没有任何变化，深水井的地下水的温度变化大多数属于F型（47．9％）。从表面上看，地下水水位的深浅似乎与地下水温度的变化模式有关。例如．温度变化属于P型或者WP型的地下水的水位最浅。而温度变化属于F型的地下水的水位最深。76．6％的浅水井地下水温度的年变化范嗣小于8℃，而97．1的深水井地下水温度的年变化范围小于8℃。通常，在最冷的月份（11月-月）地下水的温度最高，而在3—6月份（仅在最热的月份（7月—8月）之前）地下水的温度最低。研究发现．地下水温度和环境气温之间的相位差，与地下水温度的变化范同之间存在单纯的指数关系。这表明，气温的传播主要是通过介质传导完成的。鉴于地下水温度的稳定性，为了有效地设计和维护热泵系统。利用温度变化属于F型的基岩含水层地下水是最适宜的。为了更好地利用地下水热泵系统．对场地水文地质条件和潜在的环境变化进行详细勘查是必需的。

Plants are continuously exposed to numerous biotic stresses throughout their *** arms race-driven coevolution with pathogens,plants have developed sophisticated immune systems,including pathogen-associated molecular pattern(PAMP)-triggered immunity(PTI)and effector-triggered immunity(ETI).PTI is initiated by the binding of danger signals to extracellular membrane-localized receptors calledpattern recognition receptors(PRRs).PTI triggers responses,including reactive oxygen species(ROS)bursts and the expression of defenseassociated ***,pathogens adapted to PTl secrete virulence proteins,effectors,to aid colonization,and ETl is then triggered by the recognition of these effectors by resistance proteins with a nucleotide-binding domain leucinerich repeat receptor(NLR).To circumvent this immune response,pathogens secrete various effectors into the host intracellular region and induce effector-triggered susceptibility(Zhou and Zhang.,2020).Currently,research on plant immunity has been primarily focused on plasma membrane and cytoplasmlocalized proteins,including oligomeric NLRs,resistosomes,and the secretion mechanisms of cytoplasmic effectors.

Inverse relationship between bioavailable testosterone and subclinical coronary artery calcification in non-obese Korean men

Asian Journal of Andrology 2012年第4期14卷 612-615页

作者： Byoung-jin Park Jae-yong Shim yong-Jae lee Jung-Hyun lee Hye-Ree lee Department of Family Medicine Yonsei University College of Medicine Seou1135-720 Korea Department of Health Promotion Center Gangnam Severance Hospita Yonsei University College of Medicine Seou1135-720 Korea

Although low testosterone levels in men have been associated with high risk for cardiovascular disease, little is known about the association between male sex hormones and subclinical coronary disease in men with apparently low cardiometabolic risk. This study was performed to investigate the association between male sex hormones and subclinical coronary artery calcification measured as coronary calcium score in non-obese Korean men. We examined the relationship of total testosterone, sex hormone-binding globulin, bioavai lable testosterone and free testosterone with coronary calcium score in 291 non-obese Korean men （mean age： 52.8--- 9.3 years） not having a history of cardiovascular disease. Using multiple linear regression, we evaluated associations between log （sex hormone） levels and log （coronary calcium score） after adjusting for confounding variables in 105 men with some degree of coronary calcification defined as coronary calcium score ~〉 1. In multiple linear regression analysis, bioavailable testosterone was inversely associated with coronary calcium score （P=0.046） after adjusting for age, body mass index, smoking status, alcohol consumption, regular exercise, mean blood pressure, resting heart rate, C-reactive protein, fasting plasma glucose, total cholesterol, triglyceride, high-density lipoprotein （HDL） cholesterol, hypertension medication and hyperlipidernia medication, whereas total testosterone, sex hormone-binding globulin and free testosterone were not （P=0.674, P=O. 121 and P=O. 102, respectively）. Our findings indicate that bioavailable testosterone is inversely associated with the degree of subclinical coronary artery calcification in non-obese men.

Chronic liver inflammation:Clinical implications beyond alcoholic liver disease

引用

World Journal of Gastroenterology 2014年第9期20卷 2168-2175页

作者： Byoung-jin Park yong-Jae lee Hye-Ree lee Department of Family Medicine CHA University School of Medicine Seoul 135-720 South Korea Department of Family Medicine Yonsei University College of Medicine Seoul 135-720 South Korea

Chronic alcohol exposure can lead to alcoholic liver disease, including hepatitis, cirrhosis and hepatocellular carcinoma, and chronic inflammation can simultaneously cause systemic medical illness. Recent evidence suggests that alcoholic liver disease is a predictor for liver-related diseases, cardiovascular disease, immunologic disease, and bone disease. Chronic inflammation in alcoholic liver disease is mediated by a direct inflammatory cascade from the alcohol detoxification process and an indirect inflammatory cascade in response to gut microflora-derived lipopolysaccharides (LPS). The pathophysiology of alcoholic liver disease and its related systemic illness is characterized by oxidative stress, activation of the immune cascade, and gut-liver interactions. Integrative therapeutic strategies for alcoholic liver disease include abstaining from alcohol consumption; general anti-inflammatories such as glucocorticoid, pentoxifylline, and tumour necrosis factor-α antagonist; antioxidants such as N- acetylcysteine; gut microflora and LPS modulators such as rifaximin and/or probiotics. This review focuses on the impact of chronic liver inflammation on systemic health problems and several potential therapeutic targets.
