Resistance to human skin innate defenses is crucial for survival and carriage of Staphylococcus aureus, a common cutaneous pathogen and nasal colonizer. Free fatty acids extracted from human skin sebum possess potent antimicrobial activity against S. aureus. The mechanisms by which S. aureus overcomes this host defense during colonization remain unknown. Here, we show that S. aureus IsdA, a sur...

the objective of this study was to investigate the effects of summer savory essential oil (sseo) with cereals (based on barley or corn) on performance, rumen volatile fatty acid concentrations and some blood parameters of west azerbaijan native kids. in a randomized complete block design with a 3×2 factorial (0, 200 and 400 mg/d of sseo × barley or corn grain based diets) arrangement with 6 rep...

Fatty acid profiles and cholesterol content of whole-carcass ground tissue were compared from 26 transgenic (T) pigs expressing a bovine growth hormone gene (bGH) to 26 sibling control (C) pigs. All pigs were fed a common diet and were slaughtered at five different live weights: 14, 28, 48, 68, and 92 kg. The left side of each intact carcass was ground and tissue samples were analyzed for lipid...

Zooplankton are commonly frozen at sea In ecological studies when it is impractical to extract liplds lrnrnediately from live animals Analysis of lipids extracted from the copepod Calanus pacificus established that freezing has neghgible effects on copepod dry mass, total lipid content, or lipid composltion resulting only in shght changes in free fatty acids However, storage for 1 yr at -15°C r...

Maize shows wide differences in linoleic acid due both to total lipid content and to fatty acid profile. Therefore, diets containing the same high maize percentage (up to 55%) can differ in linoleic acid content and lead to subcutaneous fats of differing suitability for raw ham curing. Two trials were performed on heavy pigs; in the first, 60 pigs (body weight 48.7+/-5.1 kg) were fed three diet...

The objective of this study was to evaluate the inclusion vegetable oils in goat kid diets on performance, carcass traits, and meat composition, quality, fatty acid profile. Forty-eight Anglo Nubian kids were evaluated a completely randomized experimental design with four treatments, namely, control diet including 2.5% canola, sunflower, or soybean oils. animals slaughtered at 30 kg live weight...

A total of 74 pigs representing three commercially available crossbred types, Landrace (50%), Pietrain (50%) and Meishan (25%), were given food ad libitum over a 25to 115-kg growth period and serially slaughtered for physical and chemical analysis in five groups at 32, 42, 63, 82 and 114 kg live weight (W). Results are presented in the order of pig type as above. Pig types grew at similar overa...

OBJECTIVES A fatty liver is known to have impairment of microcirculation, which is worsened after ischemia reperfusion injury (IRI). This makes most fatty grafts unsuitable for transplantation, and in the absence of real time assessment of microcirculation this selection has been at best, random. The aim of this study was to demonstrate the utility of a contrast enhanced ultrasound model in qua...

Guanidinium-rich molecules, such as cell-penetrating peptides, efficiently enter living cells in a non-endocytic energy-independent manner and transport a wide range of cargos, including drugs and biomarkers. The mechanism by which these highly cationic molecules efficiently cross the hydrophobic barrier imposed by the plasma membrane remains a fundamental open question. Here, a combination of ...

Recent data suggest that omega-3 fatty acids may be effective in epilepsy, cardiovascular disorders, arthritis, and as mood stabilizers for bipolar disorder; however, the mechanism of action of these compounds is unknown. Based on earlier studies implicating omega-3 fatty acids as inhibitors of protein kinase C activity in intact cells, we hypothesized that omega-3 fatty acids may act through d...
