In order to evaluate the milk yield, milk quality, and health of dairy cows fed a high-concentrate (HC) diet, eight lactating Holstein dairy cattle were randomly assigned to HC or low-concentrate (LC) diet groups and fed for 50 days, and the auto-control studying before and after treatment with the two diets was used. During the experiment, plasma and milk samples were collected and measured. With regard to milk component, HC feeding led to higher milk production (P < 0.05), but significantly lower milk protein percentage (P < 0...

Reverse pseudohyperkalemia is a term used to describe in vitro, falsely elevated potassium concentrations in plasma specimens that occur in association with extreme leukocytosis and are commonly associated with hematologic malignant neoplasms. Tumor lysis syndrome is an in vivo lysis of tumor cells that leads to elevated levels of potassium, uric acid, phosphate, and lactate dehydrogenase, as well as decreased calcium concentrations. Herein, we report a case of a 66-year-old Caucasian man with stage IV mantle-cell lymphoma who has elevated levels of potassium, uric acid, and phosphorus, as well as a white blood cell (WBC) count greater than 100,000 cells per mm3...

This experiment was to evaluate the effect of dietary resveratrol (Res) supplementation (0, 400 mg/kg) on growth performance, meat quality, and muscle anaerobic glycolysis and antioxidant capacity of transported broilers. A total of 360 21-day-old male Cobb broilers was randomly allotted to 2 dietary treatments (Res-free group and Res group) with 12 replicates of 15 birds each. On the morning of d 42, after a 9-hour fast, 24 birds (2 birds of each replicate) were selected from the Res-free group and then equally placed into 2 crates, and the other 12 birds (one bird of each replicate) were selected from the Res group and then placed into the other crate...

Decades of genetic selection have generated 2 different, highly specialized types of chickens in which 1 type, known as the layer-type chicken, expresses high laying performance while the other type, known as the broiler-type chicken, is dedicated to the production of fast-growing birds. Selected lines for the latter type often express disorders in their reproductive performance including early sexual maturation and accelerated, non-reversible seasonal decline of their semen production and mating behavior. The aim of the present study was to characterize some metabolic markers of the Sertoli cell populations...

A single missense mutation at position 159 of coenzyme Q9 (COQ9) (G→A; rs109301586) has been associated with genetic variation in fertility in Holstein cattle, with the A allele associated with higher fertility. COQ9 is involved in the synthesis of coenzyme COQ10, a component of the electron transport system of the mitochondria. Here we tested whether reproductive phenotype is associated with the mutation and evaluated functional consequences for cellular oxygen metabolism, body weight changes, and ovarian function...

HIF-1α overexpression is associated with radio-resistance of various cancers. A radioresistant human melanoma cell model MDA-MB-435R (435R) was established by us previously. Compared with the parental cells MDA-MB‑435 (435S), an elevated level of HIF-1α expression in 435R cells was demonstrated in our recent experiments. Therefore, in the current study, we sought to determine whether selective HIF-1α inhibitors could radiosensitize the 435R cells to X-ray, and to identify the potential mechanisms. Our data demonstrated that inhibition of HIF-1α with 2-methoxyestradiol (2-MeOE2) significantly enhanced radiosensitivity of 435R cells...

BACKGROUND: The 2011 Surgeon General's Call to Action to Support Breastfeeding highlights a need for optimizing lactation-based education for all health professionals; however, few schools of nursing and medicine offer lactation-based curriculum. In an effort to address these gaps in education and care, the director of the lactation program at a large urban children's hospital developed and instituted the annual regional Human Milk Assembly (HMA), a half-day collaborative meeting of the hospital's regional and referral hospitals' neonatal intensive care unit (NICU) nursing staff, to address lactation-based educational and training needs of all participating institutions...

Background Many smokers have recently turned to electronic cigarettes (e-cigarettes) because they have been marketed as a cheaper and safer smokeless alternative to traditional cigarettes, and a possible smoking cessation tool. Even though the safety of these electronic devices is still not fully known, there is evidence of their cytotoxicity on cells which belong to the oral cavity. In a previous paper the increase of reactive oxygen production and Bax expression, followed by the occurrence of apoptosis, were demonstrated in human gingival fibroblasts...

Biological pigments or biochromes are ubiquitous in animals, plants, and simpler organisms such as fungi and bacteria. They serve a wide spectrum of functions from photosynthesis, camouflage, mimicry, photo protection from the environment to attracting mates. The human female nipple areola complex (NAC) is a highly-pigmented area. Currently, the prevailing theory as to the evolution of the pigmented human NAC is based on infant recognition of breast feeding latching zone; however, due to the protruding shape of the nipple and surrounding breast, the authors of this letter believe that the evolutionary advantage of the pigmented NAC has a direct physiological function, namely the initiation of involution at the end of the infant lactation period...

Centrally acting prolactin has been shown to have anti-stress effects by modulating the activity of the hypothalamic-pituitary-adrenal axis. We tested the hypothesis that prolactin directly targets hypothalamic corticotropin-releasing hormone (CRH) neurons. In situ hybridisation confirmed expression of mRNA encoding the long, but not the short, isoform of the prolactin receptor (PRLR) within the paraventricular nucleus (PVN) of the virgin rat; however, only 6% of CRH neurons expressed long-form Prlr mRNA. Examination of the functional response of CRH neurons to intracerebroventricular prolactin (500 ng) showed that these neurons did not respond with activation of phosphorylated signal transducer and activator of transcription 5 (pSTAT5), a marker of long-form PRLR activation...
