REVIEW
Patricia Iozzo, Elena Sanguinetti
Early nutrition and growth in the initial years of life are important determinants of later body weight and metabolic health in humans, and the current epidemic of obesity involving children requires a better understanding of causal and protective mechanisms and components in infant foods. This review focuses on recent evidence implicating feeding modes (e.g., breast milk and formula milk) and dietary transitions toward complementary foods in the progression of microbiota maturation in children. The literature exploring body weight outcomes of microbiota changes induced by diet in early life is limited...

Data from a set of different studies on the infectivity and pathogenicity of Campylobacter jejuni were analyzed with a multilevel model, allowing for effects of host species (nonhuman primates and humans) and different strains of the pathogen. All challenge studies involved high doses of the pathogen, resulting in all exposed subjects to become infected. In only one study a dose response effect (increasing trend with dose) for infection was observed. High susceptibility to infection with C. jejuni was found in a joint analysis of outbreaks and challenge studies...

INTRODUCTION: Donor milk is the second best alternative for a newborn after the mother's own milk, especially when the baby is a premature or a sick child since this milk has the advantage of protecting against necrotizing enterocolitis. There are currently 13 milk banks in Spain, however this is not sufficient to supply all Spanish neonatal units with donor milk. In order to bring donor milk to the babies in Neonatal Unit of the Regional University Hospital of Malaga, a Satellite Centre (CS) was created in 2012, depending on the Milk Bank of Virgen de las Nieves Hospital in Granada...

C-C motif chemokine ligand 2 (CCL2) is a small chemokine which belongs to the CC-type chemokine family, and has chemoattractant activity for recruitment of monocytes to sites of inflammation. Overexpressed CCL2 binding to its receptor C-C chemokine receptor 2 increases the risk of breast cancer in humans, but its effects on proliferation of bovine mammary epithelial cells is not known. Maintaining a high level of proliferative activity in bovine mammary epithelial cells during lactation is important for improving milk yield and can benefit the dairy industry economically...

Increased production of long-chain unsaturated fatty acids (LCUFA) can have a positive effect on the nutritional value of ruminant milk for human consumption. In nonruminant species, fatty acid elongase 5 (ELOVL5) is a key enzyme for endogenous synthesis of long-chain unsaturated fatty acids. However, whether ELOVL5 protein plays a role (if any) in ruminant mammary tissue remains unclear. In the present study, we assessed the mRNA abundance of ELOVL5 at 3 stages of lactation in goat mammary tissue. Results revealed that ELOVL5 had the lowest expression at peak lactation compared with the nonlactating and late-lactating periods...

BACKGROUND: An exclusive human milk diet (EHM) fortified with human milk-based fortifier decreases necrotizing enterocolitis (NEC) compared to maternal milk supplemented with preterm formula and bovine fortifier (PTF). Growth has been less with EHM and also maternal milk supplemented with donor human milk and bovine fortifier (HMBF). The objective was to evaluate the effect of a standardized feeding protocol on the growth of infants ≤1250 g birth weight supported with EHM and HMBF. The effect on the incidence of NEC was also evaluated...

Although the tuberculin test represents the main in vivo diagnostic method used in the control and eradication of bovine tuberculosis, few studies have focused on the identification of mycobacteria in the milk from cows positive to the tuberculin test. The aim of this study was to identify Mycobacterium species in milk samples from cows positive to the comparative intradermal test. Milk samples from 142 cows positive to the comparative intradermal test carried out in 4,766 animals were aseptically collected, cultivated on Lowenstein-Jensen and Stonebrink media and incubated for up to 90 days...

REVIEW
Raffaelina Mercogliano, Serena Santonicola
Bisphenol A (BPA), widely used as additive in food packaging, is an environmental and food contaminant that shows a weak estrogenic activity in general population and toxicity in the infant population. A temporary tolerable daily intake (t-TDI) of 4 μg/kg bw/day and a migration limit of 0.6 mg/kg in food from plastic materials, intended to come in contact with food, were fixed. Dietary milk is important in the human diet. The review investigated the contamination levels in human milk and along the dairy supply chain...

Qingquan Ma, Shengdi Hu, Makoto Bannai, Guoyao Wu
Milk is an important food for mammalian neonates, but its insufficient production is a nutritional problem for humans and other animals. Recent studies indicate that dietary supplementation with L-arginine (Arg) increases milk production in mammals, including sows, rabbits, and cows. However, the underlying molecular mechanisms remain largely unknown. The present study was conducted with porcine mammary epithelial cells (PMECs) to test the hypothesis that Arg enhances milk protein synthesis via activation of the mechanistic target of rapamycin (mTOR) cell signaling...

The consumption of bovine milk and meat is considered a risk factor for colon- and breast cancer formation, and milk consumption has also been implicated in an increased risk for developing Multiple Sclerosis (MS). A number of highly related virus-like DNAs have been recently isolated from bovine milk and sera and from a brain sample of a MS patient. As a genetic activity of these Acinetobacter-related bovine milk and meat factors (BMMFs) is unknown in eukaryotes, we analyzed their expression and replication potential in human HEK293TT cells...

REVIEW
J D Voss, M S Goodson, J C Leon
We propose the idea of "phenotype diffusion," which is a rapid convergence of an observed trait in some human and animal populations. The words phenotype and diffusion both imply observations independent of mechanism as phenotypes are observed traits with multiple possible genetic mechanisms and diffusion is an observed state of being widely distributed. Recognizing shared changes in phenotype in multiple species does not by itself reveal a particular mechanism such as a shared exposure, shared adaptive need, particular stochastic process or a transmission pathway...

The full potential of microfluidic techniques as rapid and accurate methods for the detection of disease-causing agents and foodborne pathogens is critically limited by the complex sample preparation process, which commonly comprises the enrichment of bacterial cells to detectable levels. In this manuscript, we describe a microfluidic device which integrates H-filter desalination with positive dielectrophoresis (pDEP) for direct enrichment of bacterial cells from physiological samples of high conductivity and viscosity, such as cow's milk and whole human blood...

OBJECTIVE: To investigate the role of donor human milk in the prevention of nosocomial infection in very low birth weight infants. MeETHODS: A total of 105 hospitalized preterm infants with a very low birth weight were enrolled. They were classified into mother's own milk feeding group, donor human milk feeding group, and preterm formula feeding group, with 35 infants in each group. The three groups were compared in terms of incidence rates of nosocomial infection, necrotizing enterocolitis, and feeding intolerance, time to full enteral feeding, and early growth indices...

Brominated flame retardants (BFRs) are a large group of widely used chemicals, which have been produced and used since 1970s. As a consequence of substantial and long-term usage, BFRs have been found to be ubiquitous in humans, wildlife, and abiotic matrices around the world. Although several reports have reviewed BFRs contamination in general, none have focused specifically on foods and human milk, and the corresponding dietary exposure. Foods (including human milk) have long been recognized as a major pathway of BFRs intake for non-occupationally exposed persons...

Hydroxyl radical (.OH) is highly reactive, and therefore very short-lived. Finding new means to accurately detect .OH, and testing the ability of known .OH scavengers to neutralize them in human biological fluids would leverage our ability to more effectively counter oxidative (.OH) stress-mediated damage in human diseases. To achieve this, we pursued the evaluation of secondary products resulting from .OH attack, using a detection system based on Fenton reaction-mediated D-phenylalanine (D-Phe) hydroxylation...

Arsenic is ubiquitous and has a potentially adverse impact on human health. We compared the distribution of concentrations of urinary inorganic arsenic plus methylated forms (uc(iAs+MMA+DMA)) in four Italian areas with other international studies, and we assessed the relationship between uc(iAs+MMA+DMA) and various exposure factors. We conducted a human biomonitoring study on 271 subjects (132 men) aged 20-44, randomly sampled and stratified by area, gender, and age. Data on environmental and occupational exposure and dietary habits were collected through a questionnaire...
