The study of pathologically normal breast epithelium of BRCA mutation carriers may yield insights into the early natural history of breast tumorigenesis. Hormone receptor expression was assessed in 24 cases of invasive breast cancer associated with a mutation in BRCA1 (n = 15) or BRCA2 (n = 9) and in 39 sporadic cases matched for patient age and tumor hormone receptor status. Expression of prog...

BACKGROUND Reliable stability and yield of RNA from breast cancer tissues are important for biobanking, clinical trials, and diagnostic testing. METHODS Aliquots of fresh primary tumor tissue from 17 surgically resected invasive breast cancers were placed into RNAlater at room temperature after tumor removal (baseline) and up to 3 hours thereafter or were snap frozen at baseline and 40 minute...

OBJECTIVE To determine the effect of the strength of applied vacuum on the flow rate and yield of breastmilk using an electric breast pump. STUDY DESIGN Twenty-one breastfeeding mothers and two expressing mothers expressed their breastmilk for 15 minutes using an electric breast pump set at their own maximum comfortable vacuum, and at one to three softer vacuums. Milk yield and flow rate were...

The effects of caponization on growth, body measurements, carcass traits, meat quality, and the mRNA expression of three genes related to lipid metabolism in Guang-xi Yellow roosters were evaluated. Thirty roosters (25 days) of similar weight were randomly divided equally into the experimental (capons, n = 15) and control (intact males, n = 15) groups. Caponization was conducted at 28 days of a...

Much effort has been devoted to the synthesis of gold nanoparticles with different shapes, including the zero-dimensional nanospheres, one dimensional nanorods, and two-dimensional nanoplates. Compared to zero or one dimensional nanostructures, the synthesis of two-dimensional nanostructures in high yield has always been more involved, often requiring complex and timeconsuming steps such as mor...

Consumer awareness of the health benefits of n-3 fatty acids is growing and is driving consumer demand for enriched food products. Enrichment of meat with n-3 fatty acids is an opportunity for the broiler production sector to add value to their product, but enrichment can increase the cost of production. A study was conducted to determine an optimal production strategy for n-3 enrichment of bro...

An experiment was performed to evaluate the effects of dietary metabolizable energy (ME) and lysine on carcass characteristics and meat quality in Arbor Acres (AA) broilers from 1 to 56 days of age. A total of 2,970 1-d-old male broiler chicks were randomly allocated to nine dietary treatments (three ME levels in combination with three lysine levels), and dietary ME and lysine concentrations we...

Dense breast tissue increases the risk of breast cancer [1,2] and can mask breast cancer, thereby resulting in false-negative mammography examinations [3]. Recently, legislation has been passed in many states of the United States that requires direct notification to women of their breast density on screening mammography, and information on supplementary screening tools such as ultrasononography...

OBJECTIVE To assess the safety, cosmetic effects, and clinical efficacy of breast-conserving surgery combined with intraoperative radiation therapy for the treatment of Chinese patients with breast cancer. METHODS Breast-conserving surgery combined with intraoperative radiation therapy was performed in 64 breast cancer patients. The postoperative short-term efficacy, safety, and cosmetic effe...

In a screening service for breast cancer the results of routine repeat tests of women will contribute more than the results of their initial tests. A comparison of first and subsequent screens in a group of high risk women suggests that the sensitivity of screening declines between first and subsequent visits, whereas its specificity improves. Despite improved specificity, the ratio of benign b...
