Les données de consommation en acides gras polyinsaturés (AGPI) de la femme allaitante sont rares bien qu’essentielles pour évaluer le niveau d’apport en acides gras du nourrisson et éventuellement orienter la mère vers une alimentation adaptée voire vers une supplémentation en acides gras essentiels. Les données INCA 2 concernant les femmes allaitantes ont été combinées aux données de composition nutritionnelle des aliments de la base de données Ciqual 2013 pour évaluer leurs apports en acides gras.

Abstract:

Différentes raisons nous ont amenés à consacrer ce numéro spécial de la revue Productions Animales aux matières grasses dans l’alimentation animale. L’équilibre lipides/protéines des produits animaux représente, depuis des décennies, un critère essentiel de leur qualité. L’objectif général des actions de sélection et des pratiques alimentaires a été de réduire le niveau d’engraissement des carcasses. Ces actions étaient confortées par le fait que des animaux plus maigres sont de meilleurs transformateurs des aliments. Dans le cas du lait, les objectifs étaient et sont différents dans la mesure

Depuis quelques années, les travaux sur l’utilisation de l’alimentation comme aide au contrôle des coccidioses ont été repris par plusieurs équipes après avoir été abandonnés avec l’introduction et le développement des anticoccidiens. L’alimentation peut intervenir aussi bien par ses constituants que par son mode de présentation, soit directement sur le développement parasitaire soit en renforçant les défenses de l’hôte ou en aidant à la guérison. Des produits naturels à action médicinale peuvent aussi avoir des effets bénéfiques.Ainsi, les acides gras n-3 ou l’artémisine agissent directement

Beer also contains bitter hop compounds, which are toxic to Gram-positive and Gram-negative bacteria, and contribute to preventing the spoilage of this beverage.

The oil was obtained by cold pressing and physicochemical properties were determined; the fatty acid profile was determined by Gas chromatography. The mean oil yield from pressing was 16%, the refractive index of chia seed oil at 25 °C ranged from 1.4811 to 1.4832, specific gravity ranged from 0.9616 to 0.9629, acidity index and free fatty acids content ranged from 0.0345-0.0808 mg KOH/g oil, and 0.1736-0.4061%, respectively. The matter in volatiles ranged from 0.047-0.086%. The saponif

Abstract:

The cell walls of Gram-positive bacteria contain a variety of glycopolymers (CWGPs), a significant proportion of which are covalently linked to the peptidoglycan (PGN) scaffolding structure. Prominent CWGPs include wall teichoic acids of Staphylococcus aureus, streptococcal capsules, mycobacterial arabinogalactan, and rhamnose-containing polysaccharides of lactic acid bacteria. CWGPs serve important roles in bacterial cellular functions, morphology, and virulence. Despite evident differences in composition, structure and underlaying biosynthesis pathways, the final ligation step of CWGPs to th

Abstract:

Bacterial resistance to antibiotics threatens the ability to treat life-threatening bloodstream infections. Oligonucleotides (ONs) composed of nucleic acid mimics (NAMs) able to inhibit essential genes can become an alternative to traditional antibiotics, as long as they are safely transported in human serum upon intravenous administration and they are carried across the multilayered bacterial envelopes, impermeable to ONs. In this study, fusogenic liposomes were considered to transport the ONs and promote their internalization in clinically relevant bacteria. Locked nucleic acids and 2′-OMeth

Abstract:

Antibiotic resistance is a growing public health concern. Because only a few novel classes of antibiotics have been developed in the last 40 years, such as the class of oxazolidinones, new antibacterial strategies are urgently needed (Coates, A.R. et al., 2011). Nucleic acid-based antibiotics are a new type of antimicrobials. However, free nucleic acids cannot spontaneously cross the bacterial cell wall and membrane; consequently, their intracellular delivery into bacteria needs to be assisted. Here, we introduce an original lipopolyplex system named liposome polymer nucleic acid (LPN), capabl

This study aims at investigating the chemical composition, antimicrobial and antioxidant activity of some extracted essential and fixed oils from leaves of Eucalyptus microtheca plant grown in Iraq. Analysis of the isolated oils has been achieved by gas chromatography coupled with mass spectrometry gas chromatography–mass spectrometry (GC-MS) Technology. The study reveals existence of sixteen compounds. Camphene (20.60%), 4-carene (18.53%), 1,8-cineole (11.96%), terpin-4-ol (8.70%) and p-cymene (8.39%) were the highest components in these essential oils. While nine compounds were obtained as f

Abstract:

The inability of humans to synthesize essential amino acids (EAA) necessitates the need to increase the levels of these nutrient molecules in certain foods in which they are deficient. Maize ogi is a typical food product for both infants and adults in Africa, but with poor EAA content. This study therefore sought to assess the possibility of increasing the EAA content in maize ogi by processing it with cheese whey instead of water. Maize ogi and whey-fortified ogi were prepared by the usual procedure of grain soaking, milling, and drying. Samples from both treatments were subjected to proximat

Abstract:

The Toxoplasma gondii protein GRA2 is secreted into the parasite-containing vacuole where it is rapidly and specifically targeted to a network of membranous tubules that connect with the vacuolar membrane. To examine the molecular basis of this association, we expressed an HA9 epitope-tagged form of GRA2 by stable transformation of Toxoplasma. GRA2-HA9 was correctly packaged inside the dense granules, secreted into the PV and targeted to the network, as shown by immunoelectron microscopy, immunofluorescence and cell fractionation.

Abstract:

ABSTRACT To identify the Toll-like receptor 2 ligand critically involved in infections with gram-positive bacteria, lipoprotein lipase (LPL) or hydrogen peroxide (H2O2) is often used to selectively inactivate lipoproteins, and hydrofluoric acid (HF) or platelet-activating factor-acetylhydrolase (PAF-AH) is used to selectively inactivate lipoteichoic acid (LTA). However, the specificities of these chemical reactions are unknown. We investigated the reaction specificities by using two synthetic lipoproteins (Pam3CSK4 and FSL-1) and LTAs from pneumococci and staphylococci. Changes in the structur
