Factors Associated with the Prevalence of Breastfeeding Periods in a Cohort of Spanish Primiparous Pregnant Women.

Aims: To assess factors associated with the prevalence of breastfeeding in a cohort of Spanish primiparous pregnant women to whom a health education program was applied.

Methods: Prospective, descriptive, and inferential cohort analysis with data obtained from the beginning of pregnancy to the child's year. Prevalence of breastfeeding was classified into periods or categories: (1) "non-breastfeeding"; (2) "breastfeeding until 6 months"; (3) "breastfeeding up to 12 months".

Investigating How Lysophosphatidylcholine and Lysophosphatidylethanolamine Enhance the Membrane Permeabilization Efficacy of Host Defense Peptide Piscidin 1.

Lysophospholipids (LPLs) and host defense peptides (HDPs) are naturally occurring membrane-active agents that disrupt key membrane properties, including the hydrocarbon thickness, intrinsic curvature, and molecular packing. Although the membrane activity of these agents has been widely examined separately, their combined effects are largely unexplored. Here, we use experimental and computational tools to investigate how lysophosphatidylcholine (LPC) and lysophosphatidylethanolamine (LPE), an LPL of lower positive spontaneous curvature, influence the membrane activity of piscidin 1 (P1), an α-helical HDP from fish.

Nutritional composition and technological properties determining the quality of different cuts of organic and conventional Turkey meat.

The aim of this study was to evaluate the nutritional composition and technological properties of meat from turkeys produced under organic conditions and compare them with those of turkeys produced under conventional conditions. Twenty carcasses of female B.U.

CHARMM at 45: Enhancements in Accessibility, Functionality, and Speed.

Since its inception nearly a half century ago, CHARMM has been playing a central role in computational biochemistry and biophysics. Commensurate with the developments in experimental research and advances in computer hardware, the range of methods and applicability of CHARMM have also grown. This review summarizes major developments that occurred after 2009 when the last review of CHARMM was published.

Simulating asymmetric membranes using P2 periodic boundary conditions.

Molecular dynamics (MD) simulations of symmetric lipid bilayers are now well established, while those of asymmetric ones are considerably less developed. This disjunction arises in part because the surface tensions of leaflets in asymmetric bilayers can differ (unlike those of symmetric ones), and there is no simple way to determine them without assumptions. This chapter describes the use of P2 periodic boundary conditions (PBC), which allow lipids to switch leaflets, to generate asymmetric bilayers under the assumption of equal chemical potentials of lipids in opposing leaflets.
