This study was performed to evaluate breast muscle development in chicken genotypes divergently selected for muscularity. In the first experiment, 2 commercial broiler lines (a high breast yield, HBY, and a normal breast yield broiler strain-cross, NBY) and a Leghorn line were grown up to 35 d to evaluate BW, breast weight, and breast yield. At 7 and 21 d of age, pectoralis muscle was used to e...

Abstract Strong epidemiological data exists implicating anthropometric risk factors in breast cancer aetiology. In premenopausal women the risk of breast cancer increases with increased height, yet decreases with increasing weight and BMI. Although the evidence is not strong, a counter-intuitive positive relationship between central adiposity and premenopausal breast cancer risk is emerging. In...

this study was carried out to investigate the direct and indirect responses to selection for four-week body weight (4 week body (wk bw)) and four-week breast weight (4 week breast weight (wk brw)) and to determine the genetic contribution of reminder founders to the last generation. a total number of 351 birds were equally allocated to three lines, including two selected lines (s1 and s2 for bw...

breast cancer affects iranian women at least one decade younger than their counterparts in othercountries and the incidence of breast fibroadenoma is growing in the last two decades in tehran. thisstudy aimed to compare the ahr levels in premenopausal breast cancer and breast fibroadnemo withappropriate normal groups. possible associations of ahr with lifestyle and reproductive risk factorsand ...

background: osteopenia is common problem in premature infants. low-birth weight babies do not receive adequate amounts of calcium and phosphorus through breast feeding. this study examines the effect of calcium and phosphorus supplements on osteopenia in premature infants. methods: this clinical trial included 42 premature infants hospitalized at razi hspital in kermanshah. all the babies had a...

Numerous studies have found that increased body size (weight or body mass index) is a risk factor for breast cancer development, recurrence, and death. The detrimental relationship between body size and breast cancer recurrence may be more pronounced among women with estrogen receptor (ER)/progesterone receptor (PR)-negative breast cancer. Considering the limited availability of treatments, and...

in this study, the effect of maternal additive genetic and environment on body weight at 6 weeks (bwt6w), breast width (hbrs), carcass weight (carcwt), breast weight (brswt), blood hematocrit value (hem), residual feed intake (rfi), daily feed intake (dfi) and average daily gain (adg) were investigated in a commercial broiler dam line. with and without maternal effects, six different animal mod...

There is growing scientific evidence linking excess body weight to breast cancer risk. However, there is no common consensus on this relation due partly to methodologies used, populations studied and the cancer subtype. We report here a summary of the present state of knowledge on the role of overweight and obesity in pathogenesis of breast cancer and possible mechanisms through which excess bo...

BACKGROUND Adjuvant chemotherapy improves outcome of patients with early breast cancer. However, chemotherapy may be associated with long term toxicities. In this retrospective cohort study, the objectives were to determine body weight, body mass index (BMI), blood pressure and fasting lipids levels of young premenopausal Chinese breast cancer patients after adjuvant chemotherapy. Potential fac...

OBJECTIVE The goal of this study was to examine the associations of maternal weight status before, during, and after pregnancy with breast milk C-reactive protein (CRP) and interleukin 6 (IL-6), two bioactive markers of inflammation, measured at 1 and 3 months post partum. METHODS Participants were 134 exclusively breastfeeding mother-infant dyads taking part in the Mothers and Infants Linked...
