Background: Both Helicobacter pylori (H. pylori) cagA, vacA, iceA genotype and host IL-1B/IL-1RN polymorphisms play a role in determining the clinical consequences of H. pylori infection. This study aimed to investigate whether there might be any combinations of H. pylori cagA, vacA, iceA genotype and host IL-1B/IL-1RN polymorphisms that are particularly associated with the occurrence of gastric carcinoma in Korean patients. Methods: This study population was comprised of 239 patients with H. pylori infection: 122 with gastric carcinoma and 117 with gastritis only. DNA was isolated from gastric biopsy sample and H. pylori cagA, vacA and iceA genotype were determined by PCR. IL-1B-511 polymorphisms were genotyped by PCR-RFLP and IL-1RN polymorphisms were analyzed with variable number of tandom repeat after PCR. Results: H. pylori cagA, vacA, and iceA genotype were not associated with an increased risk for gastric carcinoma. IL-1B-511*T carriers and IL-1RN*2 carriers did not show increased risk for gastric carcinoma. On combination of bacterial/host genotypes, cagA+/IL-1B-511*T carriers and cagA+/IL-1RN*2 carriers, vacA s1/IL-1B-511*T carriers, vacA s1/IL-1RN*2 carriers, vacA m1/IL-1B-511*T carriers, vacA m1/IL-1RN*2 carriers, iceA1/IL-1B-511*T carriers, iceA1/IL-1RN*2 carriers showed no increased risk of gastric carcinoma. Conclusions: Combined H. pylori cagA, vacA, iceA genotype and host IL-1B/IL-1RN polymorphisms shows no increased risk of gastric carcinoma. Therefore, it seems other endogenous or exogenous factors may play more important role in the development of gastric carcinoma in Korean.(Korean J Med 71:24-37, 2006)

To date, velamentous insertion of umbilical cord has not been a topic of interest. It has regarded as a phenomenon without clinical significance rather than a disease. Furthermore, antenatal diagnosis of velamentous insertion has been thought as an impossible task. Recently, some investigators raised the clinical importance of velamentous insertion of umbilical cord, especially in multiple gestation. Below we report on a case of velamentous insertion of umbilical cord in discordant twins conceived by in vitro fertilization. The aim of this report is to emphasis the clinical significance of velamentous insertion of umbilical cord in twin gestation. The velamentous insertion of umbilical cord can cause twin-twin transfusion syndrome (TTTS) and pseudo TTTS. Besides, the possible correlation between the high incidence of velamentous insertion of umbilical cord and discordancy in twin pregnancy obtained by in vitro fertilization is also discussed in this report in conjunction with the case.

본 장치는 내, 외부 마찰패드간의 마찰을 통해 지진력을 상쇄시키는 것으로 몰드변압기의 좌, 우측외곽에 설치되어 약축 방향의 과다변위를 제어하는 역할을 한다. 실험은 본 장치의 성능을 검증하기 위한 선행연구로 반복가력 실험을 수행하였다. This device offsets the seismic force through friction between the internal and external friction pads and is installed on the left and right external sides of the mold transformer to control excessive displacement in the weak axis direction. The experiment was conducted to verify the performance of this device as a previous study

목적 : 사람의 초기 임신 과정에서 phosphodiesterase type IV inhibitor인 rolipram이 탈락막내 IL-12를 억제하고 이에 따라 Th-1 계열의 cytokine이 감소하고 Th-2 cytokine이 증가하는지를 규명하는 것이 목적이다. 연구 방법 : 임신 12주 이전에 계류 유산으로 진단받은 10명과 정상임신에서 임신 중절 수술을 시행받은 10명에서 자궁 소파술을 통하여 탈락막 조직을 획득한 후 조직을 rolipram으로 Objective : To assess the capability of phosphodiesterase type IV inhibitor (rolipram) to suppress IL-12 in human decidua and the subsequent changes of Th-2 cytokine (IL-10) and Th-1 cytokine (TNF-α).

초속경 라텍스개질 콘크리트(VES-LMC)는 공용중 교량바닥판 콘크리트 긴급 덧씌우기를 목적으로 개발되었 으며, 콘크리트타설 후 3시간 만에 교통개방이 가능하도록 작업성, 내구성 및 강도특성을 만족하도록 특성화된 콘크 리트이다. VES-LMC 배합은 고유의 급속경화 특성으로 인해 콘크리트 타설 초기에 높은 수화열을 수반하고, 상대적 으로 낮은 물시멘트비로 인해 자기수축에 민감하게 반응할 수 있다. 본 논문에서는 간이수화열과 초기수축 실험을 수행하여 동일슬럼프 조건과 서로 다른 슬럼프 조건에서 라텍스함량 변화가 VES-LMC의 자기수축에 미치는 영향을 평가하였다. 실험결과는 다음과 같다. 라텍스는 콘크리트 내구성 향상에만 기여할 뿐 수화열에 미치는 영향이 매우 작게 나타났다. 서로 다른 슬럼프 조건 에서 자기수축은 라텍스함량 증가에 따라 증가하였고, 증가추세는 로그함수의 형태로 나타났다. 그러나 동일 슬럼프 조건에서 라텍스함량 변화는 두 가지 실험변수가 동시에 변화하므로 자기수축 특성에 미치는 상관성이 작게 나타났다. Very-early strength latex-modified concrete (VES-LMC) was developed for the purpose of fast-track overlay of a concrete bridge deck under heavy traffic, concentrated on the workability, durability, and strength gain so that it can be opened to the traffic only three hours after its placement. The mixture of VES-LMC might accompany very high heat of hydration at early-age because of its inherent rapid hardening property and could have susceptibility to autogenous shrinkage because of its relatively low water-cement ratio. This study evaluated the effect of the latex-cement ratio(L/C) both of the constant and variable slumps on the autogenous shrinkage of VES-LMC by carrying out simple temperature rise test and early-age shrinkage experiment. Test results are as follows: The latex contributes on the enhancement of the concrete durability but has little effect on its hydration and the accompanied heat of hydration in VES-LMC. Autogenous shrinkage increased with the increase in latex-cement ratio at variable slumps and its pattern followed regularly a logarithmic increase. However, the influence of water-cement ratio and latex-cement ratios for the test specimens at constant slump on early-age autogenous shrinkage property was found to be minor due to the simultaneous effect of the two experimental variables.

This paper is wrapped around the heating wire, such as water and sewage pipes in plumbing and fire protection water pipes and winter apartments and buildings for frost protection system to prevent freezing. Characteristics of the frost protection system is a system that generates heat by supplying current to the heating wire wound around the pipe. In this paper, we will effectively control the current supplied to the heating coil and to design a system.
