Breast cancer is diagnosed in over one million women worldwide every year. Until breast cancer can be prevented, early detection offers the best chance for cure. Mammographic screening is an effective method for early detection in average-risk women. However, the sensitivity of mammography is decreased in women at high risk for breast cancer. Because of its high sensitivity, multiple investigat...

The purpose of this study was to develop an efficient way to synthesize (99m)Tc-O-[3-(1,4,8,11-tetraazabicyclohexadecane)-propyl]-tyrosine ((99m)Tc-N4-Tyrosine), a novel amino acid-based radiotracer, and evaluate its potential in breast cancer gamma imaging. Precursor N4-Tyrosine was synthesized using a 5-step procedure, and its total synthesis yield was 38%. It was successfully labeled with (9...

There has been renewed interest about what the optimal duration of postpartum amenorrhea (PPA) so that women should know in advance to use contraceptives and prevent unwanted births. The main objective of the present study (using National Family Health Survey (NFHS)-3 data) is to ascertain the duration of breast-feeding which will yield optimal contraceptive effect, that is, after how many mont...

We evaluated the effectiveness of metallic shields that were used for reduction of the breast dose in thoracic computed tomography(CT). For the evaluation, we measured breast surface dose and image standard deviation(SD)in the lung area. The metallic shields were made from bismuth, zinc, copper, and iron. The bismuth shield has been marketed and used for dose reduction. The other three metallic...

Abstract The objective of this work was to compare the zootechnical performance Dorper x Santa Inês crossbred lambs finished in grazing systems on Megathyrsus maximus Aruana cultivar pasture, with and without shading, a feedlot. Twenty-four non-castrated were used completely randomized experimental design, three following treatments eight replicates each: 'Aruana' pasture shading + supplement; ...

Adverse effects of psychotropic medication on breast-fed infants have not been studied in controlled and systematic research. Existing information comes from small case series and single case reports. These limited data confirm that psychotropics are excreted into breast milk and that the infant is exposed to them. In recent decades sufficient data have accumulated to allow psychiatrists to pre...

Atmospheric ammonia is a common problem in poultry industry. High concentrations of aerial ammonia cause great harm to broilers' health and production. For the consideration of human health, the limit exposure concentration of ammonia in houses is set at 25 ppm. Previous reports have shown that 25 ppm is still detrimental to livestock, especially the gastrointestinal tract and respiratory tract...

Breast ultrasound is an important complement to the clinical/mammographic investigation of breast lesions. This operator-dependent method entails real-time image detection and analysis and requires extensive training and experience in identifying and differentiating between benign and malignant lesions (1-4). Lesion contour and shape are considered to be the main features that allow differentia...

BACKGROUND Evidence from randomized controlled trials (RCTs) has shown a significant survival advantage of trastuzumab. Although extant work in developed countries examined economic evaluation of trastuzumab in adjuvant treatment for early breast cancer based on the 1-year treatment, there is uncertainty about cost-effectiveness of trastuzumab in the Adjuvant Treatment of early breast cancer in...

Selection for breast muscle yield and BW in commercial broilers has resulted in genotypes far different from broilers processed in the past. When comparative studies with commercial lines are conducted, it is often difficult to differentiate between carcass effects resulting from direct genetic selection vs. correlated effects that partially reflect genetic changes in BW. The objective of the p...
