  • Differential scanning calorimetry(DSC) was used as a screening technique for assessing the compatibility of some drugs with excipients. On the basis of DSC results, interaction of ibuprofen with PVP K40 was found and eutectic formations with PEG 6000 or magnesium stearate were demonstrated. Fenoprofen Ca was found to interact with PEG 6000. Naproxen showed interactions with PEG 6000, PVP K40, PVPP and Mg stearate. Interactions of tiaprofenic acid with PVP K40 or PVPP were found and eutectic formations with PEG 6000 or Mg stearate were observed. Bisoprolol hemifumarate, metoprolol tartrate and penbutolol sulfate were found to interact with lactose.

  • Headache is one of the most common reasons for neurological consultation. Headache as many causes and symptoms. Therefore, screening method using questionaire is helpful in diagnosis of headache. This paper is to propose a medical diagnostic method to grasp patient's diseases using the relations between symptoms and diseases. For this purpose, we develop an interview chart assigned IF(intuitionistic fuzzy) grade with the relation among symptoms and three labels of headache. The method can be used to classify patient's tone of diseases with certain degrees of belief and its concerned symptoms.

  • Enlargement of organs or other solid tissues usually presents as an abdominal mass. Often, abdominal masses in children are found by an unsuspected parent or by a physician during a routine examination. Most masses have no specific signs or symptoms. Abdominal masses in children require immediate attention. History and physical examination may provide clues to the diagnosis. Ultrasound examination is the most useful screening test in most cases and may identify the organ involved and clarify whether the mass is solid or cystic. CT may be necessary to make a more precise diagnosis, especially solid masses. MRI is occasionally is helpful for specific abnormalities.

  • This paper introduces new diagnostic criteria and differential diagnosis of orthostatic dizziness to help clinicians to diagnose hemodynamic orthostatic dizziness. Clinicians need to be able to discriminate hemodynamic orthostatic dizziness from other types of dizziness that are induced or aggravated when standing or walking. Measurements of the orthostatic blood pressure and heart rate are important when screening hemodynamic orthostatic dizziness. Detailed history-taking, a physical examination, and laboratory tests are essential for finding the cause of hemodynamic orthostatic dizziness. The differential diagnosis of hemodynamic orthostatic dizziness is crucial because it can be caused by various autonomic neuropathies.

  • The signaling components of high affinity IgE receptor (Fc RI) were searched by yeast-hybrid screening of the cDNA library constructed from RBL-2H3 cells. The cytoplasmic part of the Fc RI- chain was found to specifically interact with PLC 2, and further comparatives studies were conducted focusing on the differential regulation of two PLC- isoforms through Fc RI. The inhibitors of Src, Syk, and protein kinase C similarly affected the tyrosine phosporylations of PLC 1 and PLC 2 but the inhibitors of PI3-kinase and p42/44 ERK effectively inhibited the activation of PLC 1 but not PLC 2.

  • Regular high-strength carbon steel is currently the most commonly used pipe material for onshore and offshore pipelines. The corrosion of offshore pipelines is a major problem as they age. The collapse of these structures as a result of corrosion may have a heavy cost is lives and assets. Therefore, their monitoring and screening is a high priority for maintenance, which may ensure the integrity and safety of a structure. Monitoring risers and subsea pipelines effectively can be accomplished using eddy current inspection to detect the average remaining wall thickness of corroded low-alloy carbon steel pipelines through corrosion scaling, paint, coating, and concrete. A test specimen for simulating the offshore pipeline is prepared as a standard specimen for an analysis and experiment with differential bobbin eddy current sensors. Using encircling coils, the signals for the defect in the simulated specimen are analyzed and evaluated in experiments. Differential bobbin eddy current sensors can diagnose the defects in a specimen, and experiments have been carried out using the developed bobbin eddy current sensor. As a result, the most optimum coil parameters were selected for designing differential bobbin eddy current sensors.

  • Oral ulcerative and/or vesicular diseases have similar characteristics of clinical phenotypes. Detailed and careful history taking is the cornerstone of the diagnosis of oral mucosal disease. Moreover, complete screening of review of system for patient is important. Through this article, the simple ulcerative, recurrent ulcerative, acute multiple ulcer, chronic multiple ulcerative diseases will be discussed. Clinicians have to keep in mind its differential diagnosis and management.

  • Background: To determine the frequency of primary circulating prostate cells (CPC) detection according to age and serum PSA levels in a cohort of men undergoing screening for prostate cancer and to determine the diagnostic yield in those men complying with the criteria for prostate biopsy. Materials and Methods: A prospective study was carried out to analyze all men evaluated in a hospital prostate cancer screening program. Primary CPCs were obtained by differential gel centrifugation and detected using standard immunocytochemistry using anti-PSA, positive samples undergoing a second process with anti-P504S. A malignant primary CPC was defined as PSA+ P504S+, and a test positive if 1 cell/4ml was detected. The frequency of primary CPC detection was compared with age and serum PSA levels. Men with a PSA >4.0ng/ml and/or abnormal rectal examination underwent 12 core prostate biopsy, and the results were registered as cancer/no-cancer and compared with the presence/absence of primary CPCs to calculate the diagnostic yield. Results: A total of 1,117 men participated; there was an association of primary CPC detection with increasing age and increasing serum PSA. Some 559 men underwent initial prostate biopsy of whom 207/559 (37.0%) were positive for primary CPCs and 183/559 (32.0%) had prostate cancer detected. The diagnostic yield of primary CPCs had a sensitivity of 88.5%, a specificity of 88.0%, and positive and negative predictive values of 78.3% and 94.9%, respectively. Conclusions: The use of primary CPCs for testing is recommended, since its high negative predictive value could be used to avoid prostate biopsy in men with an elevated PSA and/or abnormal DRE. Men positive for primary CPCs should undergo prostate biopsy. It is a test that could be implemented in the routine immunocytochemical laboratory.

  • Differential screening을 통해 Moriguchi등 (1998)이 분리한 유전자와 상동성을 나타내는 CitMT45 유전자의 cDNA를 분리하였다. 본 실험에서 분리한 cDNA는 Moriguchi등 (1998)이 분리한 cDNA에 비해 긴 3' UTR을 가지고 있었다. 잎과 과피, 과육에서 CitMT45 유전자의 발현분석을 northern blot을 통해 수행한 결과, 발달단계에 따라 증가하는 비슷한 앙상을 관찰할 수 있었으나, 과육, 과피, 잎의 순으로 그 발현 양이 많았다. 이들의 발현조절에 대한 정보를 얻기 위해 게놈 DNA를 분리한 결과, CitMT45 게놈 구조는 3개의 exon과 2개의 intron으로 구성되어 있었고, primer extension 분석을 통해 CitMT45 유전자의 발현은 3개의 부위에서 개시되고 있음을 알 수 있었다. 전사개시부위의 5'upstream 지역에서 TATA box와 CCAAT box뿐만 아니라, 금속이온과 온도변화에 의한 조절에 중요한 부위로 알려진 cis-element를 발견하였다.

  • 해녀콩(Canavalia lineata) 뿌리혹으로부터 만들어진 cDNA library를 뿌리의 총 RNA, leghemoglobin 및 uricasell cDNA를 competitor로 사용하여 차등 혼성화반응으로 후기 뿌리혹에서 발현되며 Cno이, Cne2, Cne3, Clb2로 명명된 4개의 cDNA 클론을 얻었다. Cnod1은 벼의 cysteine proteinase를 암호화하는 유전자와 유사한데 1450nt의 전사체외 혼성화 반응을 보였으며 뿌리혹에서만 발현되고 뿌리혹 발달 후기에서 가장 높은 발현을 보였다. Cne2는 벼의 Expressed Sequence Tag의 한 종류와 유사하고 900 nt의 전사체와 혼성화 반응을 보였으며 뿌리혹에서 주로 발현되었다. Cne2는 접종 후 13일째 발현이 증폭된 후 일정하게 유지되었다. Cne2는 완두의 tonoplast 막 내재 단백질 TRG31을 암호화하는 유전자와 유사하며 뿌리에서 가장 많이 발현되었다. Cne3는 1700 nt와 1400 nt의 전사체와 혼성화반응을 보였으며 뿌리혹의 성장, 발달과 일치하는 발현 양상을 보였다. Clb2는 800 nt의 전사체와 혼성화반응을 보였으며 접종 후 8일째부터 발현이 시작되어 13일째 증폭되고 그 이후 일정한 수준을 유지하였다.
