Globally, cardiovascular diseases and chronic obstructive pulmonary disease (COPD) are the leading causes of the non-communicable disease burden. Overlapping symptoms such as breathing difficulty and fatigue, with a lack of awareness about COPD among physicians, are key reasons for under-diagnosis and resulting sub-optimal care relative to COPD. Much has been published in the past on the pathogenesis and implications of cardiovascular comorbidities in COPD. However, a comprehensive review of the prevalence and impact of COPD management in commonly encountered cardiac diseases is lacking. The purpose of this study was to summarize the current knowledge regarding the prevalence of COPD in heart failure, ischemic heart disease, and atrial fibrillation. We also discuss the real-life clinical presentation and practical implications of managing COPD in cardiac diseases. We searched PubMed, Scopus, EMBASE, and Google Scholar for studies published 1981-May 2020 reporting the prevalence of COPD in the three specified cardiac diseases. COPD has high prevalence in heart failure, atrial fibrillation, and ischemic heart disease. Despite this, COPD remains under-diagnosed and under-managed in the majority of patients with cardiac diseases. The clinical implications of the diagnosis of COPD in cardiac disease includes the recognition of hyperinflation (a treatable trait), implementation of acute exacerbations of COPD (AECOPD) prevention strategies, and reducing the risk of overuse of diuretics. The pharmacological agents for the management of COPD have shown a beneficial effect on cardiac functions and mortality. The appropriate management of COPD improves the cardiovascular outcomes by reducing hyperinflation and preventing AECOPD, thus reducing the risk of mortality, improving exercise tolerance, and quality of life.

It has now been well documented in a variety of models that T regulatory T cells (Treg cells) play a pivotal role in the maintenance of self-tolerance, T cell homeostasis, tumor, allergy, autoimmunity, allograft transplantation and control of microbial infection. Recently, Treg cell are isolated and can be expanded in vitro and in vivo, and their role is the subject of intensive investigation, particularly on the possible Treg cell therapy for various immune-mediated diseases. A growing body of evidence has demonstrated that Treg cells can prevent or even cure a wide range of diseases, including tumor, allergic and autoimmune diseases, transplant rejection, graft-versus-host disease. Currently, a large body of data in the literature has been emerging and provided evidence that clear understanding of Treg cell work will present definite opportunities for successful Treg cell immunotherapy for the treatment of a broad spectrum of diseases. In this Review, I briefly discuss the biology of Treg cells, and summarize efforts to exploit Treg cell therapy for autoimmune diseases. This article also explores recent observations on pharmaceutical agents that abrogate or enhance the function of Treg cells for manipulation of Treg cells for therapeutic purpose.

Forty-eight patients with significant left main coronary artery obstruction underwent coronary artery bypass graft between September,1989 and September,1993. They consisted of 29 males and 19 females with the mean age of 58 [range 33 - 78 . Seventeen patients[35% had stenosis in left main coronary artery only and twenty-nine[61% had associated lesions in other coronary artery systems as well.Two[4% had isolated left coronary ostial lesion. The operative mortality was 4.17% [2/48 which is comparable to the mortality of overall coronary artery bypass surgery cases during the same period[p >0.05 . Perioperative myocardial infarction was occurred in two patients[4.17% . And the infarction rates between the two groups also showed no difference[p >0.05 . The forty-six survivors showed significant improvement in exercise tolerance as well as symptomatology. We conclude that surgery for left main coronary artery disease can be done with no increased risk through careful anesthesia,surgery, and aggressive postoperative care in the critical period.

Kidney allograft transplantation is the most effective method of renal replacement for end stage renal disease patients. Still, it is another kind of 'disease', requiring immunosuppression to keep the allograft from rejection(allograft immune reaction). Immune system of the allograft recipient recognizes the graft as a 'pathogen (foreign or danger)', and the allograft-recognizing commanderin-chief of adaptive immune system, T cell, recruits all the components of immune system for attacking the graft. Proper activation and proliferation of T cell require signals from recognizing proper epitope(processed antigen by antigen presenting cell) via T cell receptor, costimulatory stimuli, and cytokines(IL-2). Thus, most of the immunosuppressive agents suppress the process of T cell activation and proliferation.

Serological surveillance programs in animal populations are becoming increasingly important to estimate prevalence of a specific disease and subsequently to document disease-free status in a region or a country. For these purposes, the programs need to be based on both theoretical and economical aspects from the designing phase. From Aujeszky's disease (AD)-eradication program point of view, group of animals (aggregates, herds) not individual animal is the more important sampling unit of concern. In this study the authors therefore attempted to compute an appropriate sample size tailored to a current surveillance program against AD, assuming that the goal of this program is either herd-level prevalence estimation or documentation of AD-freedom. For prevalence estimation, assuming a finite population with imperfect sensitivity (Se) and specificity (Sp) of ELISA kit for AD diagnosis, the number of herds present, expected herd prevalence, and desired accuracy for a certain level of confidence, sample size was estimated at herd-level in the first stage and individual animal-level in the second stage. A two-stage sampling design was used to calculate a sample size to indicate AD-freedom. In this instance, the computation was based on the possible detection of a predetermined prevalence at a certain herd-level Se and Sp. This study indicated that the sample size varied with predetermined confidence, tolerance, Se and Sp at herd- and animal-level, and within- and among-herd prevalence. In general, smaller sample size was required to estimate AD prevalence than to document of AD-freedom. Compared to individual-based samples, two-stage sampling strategy requires a larger sample size to show disease-freedom. Statistical considerations including herd-level test characteristics when designing surveillance program also are further discussed.

저온은 식물 생장을 저해하는 주된 요인이며 병원균에 대한 감수성을 증가시킨다. 그러므로 식물체에서 스트레스 내성을 증대시키는 것은 불리한 환경 조건에서 살아남기 위한 중요한 전략이다. 본 실험의 목적은 고추 묘에서 저온 내성과 식물병 발생에 대한 외생 살리실산(SA)과 일산화질소(NO) 처리의 효과를 밝히는 것이다. 정식 후 23일 동안 고추 묘(Capsicum annuum L. '기대만발')는 온도 $20/25^{\circ}C$(낮/밤), 광주기 15시간, 광도 $145{\pm}5{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$의 정상적인 생육환경에서 자랐다. 1주일에 2번 계면활성제 0.1%를 포함한 SA와 NO 3mL을 고추 묘에 각각 분사해주었다. 처리 후 고추 묘는 암 상태에서 6시간 동안 $4^{\circ}C$ 저온에 노출시킨 후 정상적인 생육환경에서 2일 동안 회복시켜주었다. 저온 스트레스에 대한 식물 내성을 평가하기 위해 저온 처리 후 생육특성, 엽록소 형광 값, 세포막 투과성을 측정하였다. 총 페놀릭 농도와 항산화도는 실험하는 동안 측정하였다. 또한, 고추의 점무늬병과 풋마름병 발생 정도도 조사하였다. 저온 처리 전 후를 비교하여 대조구 고추묘에서는 저온에 의해 상대적으로 많은 수분을 손실하여 건물율이 높지만 SA와 NO 처리 된 고추 묘는 비슷한 건물율을 유지하였다. 저온 처리 후 대조구에 비해 SA와 NO 처리구의 전해질 유출 값은 더 낮았다. 저온 처리 동안 SA와 NO 처리구의 엽록소 형광값은 약 0.8 수준으로 유지하였지만 대조구는 빠르게 감소하였다. 화학적 처리 동안 SA 처리구의 총 페놀릭 농도와 항산화도는 NO 처리구보다 높았다. 또한 저온 처리 후 대조구와 NO 처리구의 총 페놀릭 농도는 증가하였다. 고추에서 풋마름병에 대한 저항성은 SA가 보다 효과적이었다. 본 실험의 결과는 SA와 NO의 외생처리는 고추 묘의 저온 내성을 증대시켰고 병 발생 정도를 감소시키는 데 효과적이었음을 보여준다.

Genetic improvement in potato can be carried out through several approaches, as sexual crosses, somatic hybridization, mutation and genetic engineering. Although the approach is different, but the goal is the same, to get a superior cultivar. Mutation and genetic engineering are very interesting methods for genetic improvement of potato plants. Mutation by gamma-ray irradiation have been performed to get some new potato cultivars which are more resistant to disease and have higher productivity. We have carried out a mutation of some potato cultivars and obtained some excellent clones to be potentially released as new superior cultivars. By the mutation method, we have released one potato cultivar for the French fries industry, and we registered one cultivar of potato for chips, and two cultivar for vegetable potatoes. Actually we are doing multi-location trial for three clones to be released as new cultivars. Through genetic engineering, several genes have been introduced into the potato plant, and we obtained several clones of transgenic potato plants. Transgenic potato plants containing FBPase gene encoding for fructose bisphosphatase, have a higher rate of photosynthesis and higher tuber productivity than non-transgenic plants. This result suggests that FBPase plays an important role in increasing the rate of photosynthesis and potato tuber productivity. Some transgenic potatoes containing the Hd3a gene are currently being evaluated for their productivity. Over expression of the Hd3a gene is expected to increase tuber productivity and induce flowering in potatoes. Transgenic potato plants containing MmPMA gene encoding for plasma membrane ATPse are more tolerant to low pH than non-transgenic plants, indicating that plasma membrane ATPase plays an important role in the potato plant tolerance to low pH stress. Transgenic potato plants containing c-lysozyme genes, are highly tolerant of bacterial wilt diseases caused by Ralstonia solanacearum and bacterial soft rot disease caused by Pectobacterium carotovorum. Expression of c-lyzozyme gene plays an important role in increasing the resistance of potato plants to bacterial diseases.
