Dehydroepiandrosterone (DHEA), a C19 steroid synthesized predominantly by the adrenal cortex, and its sulfated precursor (DHEAS) has antiglucocorticoid and immunoprotective properties. DHEA is important in modulating inflammatory responses; therefore, we hypothesized that DHEA concentrations might be altered in bovine postpartum metritis. DHEA, DHEAS, the cortisol/DHEA-ratio (C/D-ratio) and the DHEAS/DHEA ratio were determined in cows with and without clinical metritis subcategorized by the blood leukocyte numbers...

Based on continuous anaerobic co-digestion of cow manure with available carbon slowly released corn straw, the effect of adding available carbon quickly released fruit and vegetable waste (FVW) was explored, meanwhile microbial community variation was studied in this study. When the FVW added was 5% and 1%, the methane production of the cow manure and corn straw was improved, and the start-up process was shortened. With higher proportion of FVW to 5%, the performance was superior with a mean methane yield increase of 22...

OBJECTIVE Although intracranial vessel remodeling has been observed in moyamoya disease, concerns remain regarding the effect of bypass surgery on hemodynamic changes within the internal carotid artery (ICA). The authors aimed to quantify the surgical effect of bypass surgery on bilateral ICAs in moyamoya disease and to estimate pressure drop (PD) along the length of the ICA to predict surgical outcomes. METHODS Records of patients who underwent bypass surgery for treatment of moyamoya disease and in whom flow rates were obtained pre- and postsurgery by quantitative MR angiography were retrospectively reviewed...

Food protein-induced enterocolitis syndrome (FPIES) is a non-IgE-mediated gastrointestinal food hypersensitivity usually due to cow's milk or soy. Recent researches show that fish is one of the most important triggers of FPIES in the Mediterranean countries. Due to the risk of multiple-food-FPIES, avoiding foods in the same category or that often occur together may be reasonable. The aim of this study was to evaluate the evolution and follow-up of FPIES related to fish over a period of 20 years. We describe the clinical features of our population, discuss different approaches to oral food challenges and analyse the possibility of introducing the culprit fish or other non-related fish in order to avoid unnecessary restricted diets...

Salmonella enterica subsp. enterica serovar Kentucky (S. Kentucky) is frequently isolated from dairy cows in the United States, but is an infrequent cause of human salmonellosis. To investigate the genomic features of S Kentucky strains isolated from a single dairy farm, the genomes of eight isolates were sequenced and added to the public domain.

REVIEW

Concerns about bedsharing as a risk for sudden infant death syndrome and other forms of sleep-associated infant death have gained prominence as a public health issue. Cardboard "baby boxes" are increasingly promoted to prevent infant death through separate sleep, despite no proof of efficacy. However, baby boxes disrupt "breastsleeping" (breastfeeding with co-sleeping) and may undermine breastfeeding. Recommendations enforcing separate sleep are based on 20th century Euro-American social norms for solitary infant sleep and scheduled feedings via bottles of cow's milk-based formula, in contrast to breastsleeping, an evolutionary adaptation facilitating the survival of mammalian infants for millennia...

BACKGROUND: Uncertain symptoms often emerge during an oral food challenge (OFC) and Open-OFCs with those uncertain mild symptoms are ordinarily regarded as positive. Double-blind placebo-controlled food challenges should be conducted in order to determine these associations. Nevertheless, studies regarding the diagnosis of uncertain food allergy symptoms are lacking. We examined the diagnostic decision for a food allergy based on uncertain symptoms during an Open-OFC. METHODS: We conducted an Open-OFC between August 2005 and April 2012 with 2271 cases who suspected as allergic to hen's eggs, cow's milk, or wheat...

To clarify the mechanisms underlying the development of displaced abomasum (DA), we repositioned DA in 12 cows by rolling and observed the course of redisplacement using X-ray fluoroscopy. Displacement of the abomasum was observed to follow three patterns: displacement to the left side of the abdominal cavity through the gap formed at the reticulum, atrium of the rumen and ventral sac of the rumen (n=7); displacement to the left side after cranial movement along the diaphragm (n=3); displacement to the right side after cranial movement along the diaphragm (n=2)...

The Mongolian gerbil has been a useful laboratory animal in many research fields, especially in ischemia studies. However, due to the variation of the circle of Willis (COW), the ischemic model is unstable and various. To solve this problem, we newly established an inbred strain of gerbils, restricting breeding and keeping to F23. The data on the breeding and growth of the animals are described in the present study. The genetic characteristics of F4 to F20 detected by microsatellite DNA and biochemical markers are also shown here...

BACKGROUND: Cow's milk protein allergy is the main allergic problem during the first year of life, possibly owing to immune and gastrointestinal systems poor maturation. To prevent allergic reactions, the content and type of proteins in infant formulas resemble those of breast milk. We believe that reactions are due rather to the amount than to the type of protein. OBJECTIVE: To design a new formula with cow's milk that provides the infant with the main nutrients at an affordable cost and with lower risk for the development of allergies...

Cation channels of sperm (CatSper) are sperm-specific calcium channels with identified roles in the regulation of sperm function in humans, mice, and horses. We sought to employ a comparative genomics approach to identify conserved CATSPER genes in the bovine genome, and profile their expression in reproductive tissue. We hypothesized that CATSPER proteins expressed in bull testicular tissue mediates sperm hyperactivation and their rheotactic response in the reproductive tract of the cow. Bioinformatic analysis identified all four known CATSPER genes (CATSPER 1-4) in the bovine genome, and profiling by quantitative real-time polymerase chain reaction identified site-specific variation in messenger ribonucleic acid (mRNA) expression for all four genes along the reproductive tract of the bull...

STUDY QUESTION: Is the rate and nature of chromosome instability (CIN) similar between bovine in vivo-derived and in vitro-cultured cleavage-stage embryos? SUMMARY ANSWER: There is a major difference regarding chromosome stability of in vivo-derived and in vitro-cultured embryos, as CIN is significantly lower in in vivo-derived cleavage-stage embryos compared to in vitro-cultured embryos. WHAT IS KNOWN ALREADY: CIN is common during in vitro embryogenesis and is associated with early embryonic loss in humans, but the stability of in vivo-conceived cleavage-stage embryos remains largely unknown...

BACKGROUND: For the first time, differential attraction of pathogen vectors to vertebrate animals is investigated for novel repellents which when applied to preferred host animals turn them into non-hosts thereby providing a new paradigm for innovative vector control. For effectively controlling tsetse flies (Glossina spp.), vectors of African trypanosomosis, causing nagana, repellents more powerful than plant derived, from a non-host animal the waterbuck, Kobus ellipsiprymnus defassa, have recently been identified...

Methionine is the limiting amino acid for milk protein synthesis in dairy cows. The effect of methionine availability on milk protein synthesis is dependent on its active transport into cells through amino acid transporters. L-type amino acid transporter 1 (LAT1), which induces the transport of neutral amino acids, is highly expressed in lactating mammary gland. However, the effect of methionine on LAT1 expression and the mechanism governing this process in dairy cow mammary gland are poorly understood. In this study, we show that treatment of dairy cow mammary epithelial cells with increasing concentrations of methionine for 24 h resulted in increased expression of LAT1 and its associated protein 4F2 heavy chain (4F2hc)...

Rotaviruses C (RVCs) have been detected in pigs, humans, cows, ferrets and dogs. Despite their zoonotic impact and pathogenicity, the genetic characterization of RVCs is incomplete, unlike rotaviruses A (RVAs), whose genetics are well studied. Several studies reported partial and complete genomic sequences for multiple porcine and canine RVCs. We aimed to establish a complete genome-based genotyping system for RVCs, by analysing complete genome data from 22 porcine RVCs identified in Japan from 2002 to 2010, along with those from multiple human, bovine, porcine, canine and ferret RVCs reported in several previous studies...

The present study aimed to investigate the serum metabolomic profiles in genetically modified cows carrying and expressing human lactalbumin α (LALBA) and non‑LALBA cows, and identify altered metabolic characteristics following the genetic modification. Serum biochemistry indexes were measured according to protocols recommended by International Federation of Clinical Chemistry. The metabolomic profiles were determined using the serum samples collected from LALBA (n=6) and non‑LALBA cows (n=6). Welch's two‑sample t‑test was used to identify the metabolites that significantly differed between the LALBA and non‑LALBA groups (fold‑change ≠ 1 and P<0...

Despite the well-known importance of an adequate colostral immunoglobulin (Ig) transfer to calf health and survival, failed transfer of passive immunity (FTPI) remains a widespread problem in dairy farming. The aim of this study was to investigate the management factors associated with FTPI in newborn calves, evaluating particularly the combined effect of delivery time, amount and quality of the first colostrum meal. The study was conducted from March to August 2014 on 21 Italian dairy farms. Farmers were asked as first to answer a farm-level questionnaire on calf management...

Selection in native local breeds needs great carefulness due to the small population size and the risk of inbreeding. Furthermore, most breeds are dual-purpose, and milk and beef attitudes are antagonistic. For preservation purposes functional traits need to be considered. Focusing on the small local Rendena cattle, this study aimed to analyse the genetic correlations among milk, beef and udder health traits and the response to selection predicted under different scenarios. The study considered milk, fat and protein yields (MY), factor scores for udder volume (UV), conformation (UC) and muscularity obtained from type traits scored on primiparous cows, and performance test traits (PT) measured on young bulls at test station: average daily gain, in vivo SEUROP fleshiness, in vivo dressing percentage...

Prions are infectious proteins that cause fatal neurodegenerative disorders including Creutzfeldt-Jacob and bovine spongiform encephalopathy (mad cow) diseases. The yeast [PSI+] prion is formed by the translation-termination factor Sup35, is the best-studied prion, and provides a useful model system for studying such diseases. However, despite recent progress in the understanding of prion diseases, the cellular defense mechanism against prions has not been elucidated. Here, we report that proteolytic cleavage of Sup35 suppresses spontaneous de novo generation of the [PSI+] prion...
