An investigation into the effect of clinical ultrasound exposure on adherent microbubbles is described. A flow phantom was constructed in which targeted microbubbles were attached using biotin-streptavidin linkages. Microbubbles were insonated by broadband imaging pulses (centred at 2.25 MHz) over a range of pressures (peak negative pressure (PNP) = 60-375 kPa). Individual adherent bubbles were...

the present research aimed to study the growth and reproductive parameters of common kilka clupeonella caspia in southern caspian sea in 2010. after measuring the length and weight of 3774 samples, they were dissected, sex determined and female gonads were weighed. sexual maturity classification was carried out based on six stages. age was determined using sagitta otoliths. length-weight relati...

BACKGROUND The IUCD, primarily in the form of copper IUD is used by more than 150 million women around the world, making it the most widely used reversible method of contraception. The objective of this study is to do double blind clinical trial to compare the side effects of Copper-T and Cu 375 IUCD in women using contraceptive method and had used no contraception before.

This study was designed to assess the immune status of the Korean population against varicella-zoster virus (VZV) through a seroepidemiologic study. Residual blood samples were collected from diagnostic laboratories throughout Korea. Samples were collected in October 2009 to March 2010 from persons 0-79 yr of age and were tested by ELISA (Enzygnost®; Dade Behring, Schwalbach, Germany). Total se...

Health risk appraisal (HRA) is a tool for determining health risk factors and motivating individuals to maintain a healthy lifestyle. We performed this study to describe the HRA algorithm and evaluate the accuracy of an HRA program for 10-yr mortality prediction in Korean men. We used data derived from periodic health examinations of 116,927 male public officials and school personnel aged 20 or...

RATIONALE One of the limitations associated with lung transplantation is the lack of available organs. OBJECTIVE To determine whether a lung donor-management protocol could increase the number of lungs for transplantation without affecting the survival rates of the recipients. METHODS We implemented the San Antonio Lung Transplant protocol for managing potential lung donors according to mod...

DNA ploidy of melanocytic skin tumors from 87 patients (53 primary melanomas, 34 nevi) was determined by flow cytometry from routinely prepared paraffin blocks. Ploidy data correlated strongly with conventional morphological parameters. Only 1 of 34 nevi, but 13 of 53 melanomas were aneuploid. Among the melanomas, none of 21 levels I-III melanomas was aneuploid, but 13 of 32 levels IV and V mel...

this study investigated whether age and gender influenced blood pressure recovery after exhaustive exercise in non-athletic males and females. 60 healthy (blood pressure was especially considered) men and women with no drug and supplement consumption participated in this study and were divided into six groups: 20-30 yr (10 males), 20-30 yr (10 females), 30-40 yr (10 males), 30-40 yr (10 females...

Increased cardiovascular morbidity and mortality were reported in GH deficiency (GHD), and GH replacement can ameliorate cardiac abnormalities of adult GHD patients. To test the potential progression of untreated GHD on the cardiovascular risk and cardiac function, cardiovascular risk factors, cardiac size, and performance were prospectively evaluated in 15 GHD patients (age, 18-56 yr) who were...
