Objectives : Asthma is a chronic inflammatory disorder in which the airway smooth muscle undergoes exaggerated constriction and is abnormally responsive to external stimuli and clinically manifests dyspnea, cough, and wheezing. Recently in Korea, the number of asthma patients has tended to increase as air pollution increases and new allergens appear. This study aimed to identify the therapeutic effects of Sochongryong-tang, which has been used on asthmatic patients in Oriental Medicine for a long time. Methods : We studied 10 asthmatic patients who had visited the Division of Respiratory System, Department of Internal Medicine of Kyunghee Oriental Medical Center from February 1, 2001 to June 30, 2001, which examined the patients by the pulmonary function test (PFT) and Quality of Life Questionnaire for adult Korean Asthmatics (QLQAKA) before and after taking Sochongryong-tang for two weeks. The data was analyzed using paired t-test. Results : After treatment with Sochongryong-tang for two weeks, FEV 1.0 showed a significant increase of 14.2%, FVC a significant increase of 9.3% and PEFR a significant increase of 16.2% in results of patients examined asthmatic by PFT. In the results of QLQAKA, the mean of scores increased significantly over 0.5 points in total score, symptom domain, emotion domain, and environmental domain. Conclusions : This study shows that Sochongryong-tang has the effect of improvements of pulmonary function and quality of life in asthmatic patients.

An approach to achieving the ambitious goal of cost effectively extending the safe operation life of energy pipeline to 100 years is the application of health monitoring and life prediction tools that are able to provide both long-term remnant pipeline life prediction and in-situ pipeline condition monitoring. A critical step is the enhancement of technological capabilities that are required for understanding and quantifying the effects of key factors influencing buried steel pipeline corrosion and environmentally assisted materials degradation, and the development of condition monitoring technologies that are able to provide in-situ monitoring and site-specific warning of pipeline damage. This paper provides an overview of our current research aimed at developing new sensors and electrochemical cells for monitoring, categorising and quantifying the level and nature of external pipeline and coating damages under the combined effects of various inter-related variables and processes such as localised corrosion, coating cracking and disbondment, cathodic shielding, transit loss of cathodic protection.

This study utilized data (a sample of 18,553 people born in 1958 in England, Scotland, and Wales) from the National Child Development Study of 1968 and 1991 to explore the influence of familial difficulties on the internalizing behavioral patterns during the early adolescent period and late life outcomes periods. In this paper, internalizing behavioral problems include 'depression', 'anxiety', 'hostility to adults', 'hostility to children', and 'withdrawal'. Late outcomes were analyzed in two different variables and one marital management domain: 'unemployment', 'seen doctors about emotional problems', 'divorce or separation; never lived as a couple; arguments end in violent behavior' The results indicate that young adolescents who had experienced familial difficulties also have internalizing behavioral problems giving them emotional and behavioral instability. The findings also show that familial difficulties during childhood positively contribute to late life outcomes such as unemployment, emotional problems, and marital management. This study suggests that in order to effectively respond to the needs of children and adolescents who have experienced various familial difficulties, counselors and educators must guide parents.

Purpose: Hope has been identified as a protective factor that contributes to achieving a better quality to life, especially in patients with chronic disease. The purpose of this review was to synthesize current knowledge about the relationship between hope and quality of life among adolescents living with chronic illnesses. Methods: We searched major English-language databases (PsycINFO, PubMed, and CINAHL) for studies from January 1, 2002 to July 12, 2019. Studies were included if they provided data on hope and its relationship with quality of life among adolescents with chronic diseases. Results: In total, five articles were selected from the 336 studies that were retrieved. All five studies reported a positive correlation between hope and quality of life, such that people with a higher level of hope had a better quality of life. Hope was found to have direct and indirect effects on quality of life in adolescents with chronic diseases. Conclusion: Healthcare professionals should make more efforts to enhance hope in adolescents with chronic diseases in order to improve their quality of life. Future studies exploring how hope develops in adolescents with chronic diseases and the long-term impact of hope on quality of life are necessary.

Although the evolution of Arabidopsis thaliana and humans diverged approximately 1.6 billion years ago, recent studies have demonstrated that protein function and cellular processes involved in disease response remain remarkably conserved. Particularly, γ-secretase, a multisubunit protein complex that participates in intramembrane proteolysis (RIP) regulation, is also known to mediate the cleavage of more than 80 substrates including the amyloid precursor protein (APP) and the Notch receptor. Although the genes (PS1/2, APH-1, PEN-2, and NCT) coding for the γ-secretase complex components are present in plant genomes, their function remains largely uncharacterized. Given that the deposition of 42 amino acid long amyloid-β peptides (hAβ₄₂) is thought to be one of the main causes of Alzheimer's disease, we aimed to examine the physiological effects of hAβ₄₂ peptides on plants. Interestingly, we found that Arabidopsis protoplast death increased after 24 h of exposure to 3 or 5 µM hAβ₄₂ peptides. Furthermore, transgenic Arabidopsis plants overexpressing the hAβ₄₂ gene exhibited changes in primary root length and silique phyllotaxy. Taken together, our results demonstrate that hAβ₄₂ peptides, a metazoan protein, significantly affect Arabidopsis protoplast viability and plant morphology.

Acetaminophen [Paracetamol, N-acetyl-para-aminophenol (APAP)] is a common over-the-counter analgesic agent as nonsteroidal anti-inflammatory drugs (NSAIDs). The high doses or the long-term treatment of acetaminophen via usual gavage feeding resulted in damage of testicles that presented recoverable impairment, as well as liver and kidney. The influence of acetaminophen was examined in male golden hamsters treated with acetaminophen-containing diet feeding. They were divided into 5 groups and subjected to this experiment for 4 weeks: animals housed in long photoperiod (LP) as LP control, animals housed in short photoperiod (SP) for 4 weeks as SP control (SP4), and groups of animals treated with low, middle, and high concentrations of acetaminophen (Low, Middle, High groups). Also animals housed in SP for 8 weeks were included (SP8) to contrast testicular activities, if necessary. As results, spermatozoa filled the seminiferous tubules of the testicles of animals in LP control and SP4 groups. The aspects were seen in the animals taken diets of low and middle doses of acetaminophen. The animals who fed high dose of acetaminophen showed large or small testicles. The large testicles displayed all germ cells at the steps of spermatogenesis. The small testicles presented no sperm as the animals housed in SP for 8 weeks. Thus these results indicate that acetaminophen invokes the antigonadal effects and accelerates the regressing process of the testicles in the animals compared to the animals exposed to SP.
