Dextrans synthesised by three Leuconostoc mesenteroides strains, isolated from mammalian milks, were studied and compared with dextrans produced by Lc. mesenteroides and Lactobacillus sakei strains isolated from meat products. Size exclusion chromatography coupled with multiangle laser light scattering detection analysis demonstrated that the dextrans have molecular masses between 1.74×10(8)Da and 4.41×10(8)Da. Rheological analysis of aqueous solutions of the polymer revealed that all had a pseudoplastic behaviour under shear conditions and a random, and flexible, coil structure...

TBBPA and HBCDs are the two classes of flame retardants that are still allowed for use by the European Commission. In May 2013, HBCDs were listed as Persistent Organic Pollutants under the Stockholm Convention, and they were banned with an exemption on EPS/XPS for cavity wall insulation. This study describes the development and optimisation of a rapid LC-ESI-MS/MS method using isotopic dilution quantification including a simplified extraction step using a mixture of solvents and sulphuric acid hydrolysis followed by the one-shot analysis of TBBPA and each of the α-, β- and γ-HBCD diastereoisomers...

Despite numerous health benefits for babies and mothers, many women do not either initiate or continue breastfeeding for the recommended duration, and increasing breastfeeding is a national priority. It is important to understand media messages on the topic, given that breastfeeding is influenced by many environmental factors and that perceived norms, social support, and perceptions of difficulties predict breastfeeding. The current study analyzes how media covers (1) breastfeeding in general, (2) public breastfeeding, and (3) extended breastfeeding (past 1 year)...

Streptomyces sp. are bacteria recognized as the producers of more than half of the known bioactive compounds. Developing appropriate preservation methods for industrial strains of Streptomyces is necessary, as continuous subculture could have significant negative effects on their characteristics, including their potential to produce secondary metabolites. The effects of two common preservation methods on a bioactive metabolite producer, Streptomyces zagrosensis UTMC 1154, were studied. In the cryopreservation method, glycerol and dimethyl sulfoxide (DMSO) were evaluated as cryoprotectants...

During the last years, phospholipids (PLs) have attracted great attention because of their crucial roles in providing nutritional values, technological and medical applications. There are considerable proofs that PLs have unique nutritional benefits on human health, such as reducing cholesterol absorption, improving liver functions, and decreasing the risk of cardiovascular diseases. PLs are the main structural lipid components of cell and organelle membranes in all living organisms, and therefore, they occur in all organisms and the derived food products...

Vegetable milks are considered as functional foods due to their physiological benefits. Although the consumption of these products has significantly increased, they have received little attention in legislation, as regard to contaminants. However, they may contain mycotoxins resulting from the use of contaminated raw materials. In this work, ultra-high performance liquid chromatography tandem mass spectrometry has been proposed for the determination of the most relevant Fusarium toxins (fumonisin B1 and B2, HT-2 and T-2 toxins, zearalenone, deoxynivalenol and fusarenon-X) in different functional beverages based on cereals, legumes and seeds...

The genetic markers in inflammatory responses during mastitis afford a reasonable way for improving milk production in the Egyptian buffalo breed. Among them is the interleukin 8 Receptor Gene (IL8RB) (CXCR2); a chemokine receptor gene augments the neutrophil migration during infection. To understand its role better during mastitis in Egyptian buffalos, twenty-five dairy animals representing the normal, sub-clinically, clinically and chronically affected buffalos were randomly selected from different districts...

The proteolytic system of Lactobacillus plays an essential role in bacterial growth, contributes to the flavor development of fermented products, and can release bioactive health-beneficial peptides during milk fermentation. In this work, a genomic analysis of all genes involved in the proteolytic system of L. delbrueckii subsp. lactis CRL 581 was performed. Genes encoding the cell envelope-associated proteinase, two peptide transport systems, and sixteen peptidases were identified. The influence of the peptide supply on the transcription of 23 genes involved in the proteolytic system of L...

In a previous genome-wide association study (GWAS) on milk production traits in a Chinese Holstein population, we revealed that GPIHBP1 is a novel promising candidate gene for milk fat content traits. In this study, we performed over-expression and RNAi experiments on GPIHBP1 in bovine primary mammary epithelial cells. The results showed that the expression of several important milk fat-related genes (LPL, CD36, VLDLR, ACACA and FASN) increased or decreased when the expression of GPIHBP1 was up- or down-regulated...

Comprehensive explanation about milk oversupply is not available in the current literature because few studies have been done on this topic. In traditional Persian medicine, milk oversupply and its management have been described. The aim of this study was to investigate milk oversupply from the perspective of medieval Persian practitioners. In this study, some main medical resources of traditional Persian medicine such as Al-Havi and the Canon of Medicine were studied to extract valuable information about milk oversupply...

Human milk contains essential micronutrients for growth and development during early life. Environmental pollutants, such as potentially toxic metals, can also be transferred to the infant through human milk. These elements have been well-studied, but changing diets and environments and advances in laboratory technology require re-examining these elements in a variety of settings. The aim of this study was to characterize the concentrations of essential and toxic metals in human milk from four diverse populations...

Caprine brucellosis is a chronic infectious disease caused by the gram-negative cocci-bacillus Brucella melitensis. Middle- to late-term abortion, stillbirths, and the delivery of weak offspring are the characteristic clinical signs of the disease that is associated with an extensive negative impact in a flock's productivity. B. melitensis is also the most virulent Brucella species for humans, responsible for a severely debilitating and disabling illness that results in high morbidity with intermittent fever, chills, sweats, weakness, myalgia, abortion, osteoarticular complications, endocarditis, depression, anorexia, and low mortality...

Sow immunity plays an important role in preventing viral infection and disease in newborn piglets. Vertical transmission of porcine circovirus type 2 (PCV2) may perpetuate porcine circovirus associated disease (PCVAD) in newborn and growing pigs. Hence, the immunological effects of maternal immunoglobulin transfer of PCV2-specific antibodies on PCV2 viremia and immune response in piglets in commercial swine herds were evaluated. Sow vaccination has been shown to reduce viral shedding and viremia, and increases the neutralizing antibody (NA) titers...

One of the most critical junctures for community support of breastfeeding is the mother's return to work. When breastfeeding workers have access to both time and space for expressing breast milk, they are more likely to breastfeed for the recommended term, yet many mothers still struggle to access these simple accommodations in their workplace. Healthcare providers can and should aid nursing mothers in accessing these accommodations. One tangible way to offer support for continued breastfeeding upon return to work is to provide notes for lactation accommodation in the workplace...

There is conflicting evidence on the protective role of breastfeeding in relation to the development of allergic sensitisation and allergic disease. Studies vary in methodology and definition of outcomes, which lead to considerable heterogeneity. Human milk composition varies both within and between individuals, which may partially explain conflicting data. It is known that human milk composition is very complex and contains variable levels of immune active molecules, oligosaccharides, metabolites, vitamins and other nutrients and microbial content...

Animal-friendly, economical, resource-saving milk production provides the basis for sustained consumer acceptance. Bovine mastitis plays a decisive role in the dairy industry-disturbing animal health and welfare and causing considerable economic losses on the other hand. Currently, antimicrobial treatment is indispensable to keep bovine udder health, animal welfare and economic aspects in balance. On the contrary, emergence and spread of antimicrobial resistance (AMR) is an urgent matter of particular public interest, and as a consequence, antimicrobial usage (AMU) in production livestock is a critically discussed subject...
