The composition of commercially available human embryo culture media.

Study Question: What is the composition of currently available commercial human embryo culture media provided by seven suppliers, for each stage of human preimplantation embryo development?

Summary Answer: While common trends existed across brands, distinct differences in composition underlined the absence of a clear standard for human embryo culture medium formulation.

What Is Known Already: The reluctance of manufacturers to fully disclose the composition of their human embryo culture media generates uncertainty regarding the culture conditions that are used for human preimplantation embryo culture. The critical role of the embryo culture environment is well-recognized, with proven effects on IVF success rates and child outcomes, such as birth weight.

Systematic review and meta-analysis of efficacy and safety of continuous positive airways pressure versus high flow oxygen cannula in acute bronchiolitis.

Introduction: There are a trend towards increasing use of High-Flow Nasal Cannula (HFNC), outside of paediatric intensive care unit. Give this trend is necessary to update the actual evidence and to assess available published literature to determinate the efficacy of HFNC over Continuous Positive Air Pressure (CPAP) as treatment for children with severe bronchiolitis.

Methods: We searched MEDLINE, EMBASE, LILACS, and COCHRANE Central, and gray literature in clinical trials databases ( www.

Preclinical evaluation of collagen type I scaffolds, including gelatin-collagen microparticles and loaded with a hydroglycolic Calendula officinalis extract in a lagomorph model of full-thickness skin wound.

Previously, we have developed collagen type I scaffolds including microparticles of gelatin-collagen type I (SGC) that are able to control the release of a hydroglycolic extract of the Calendula officinalis flower. The main goal of the present work was to carry out the preclinical evaluation of SGC alone or loaded with the C. officinalis extract (SGC-E) in a lagomorph model of full-thickness skin wound.

Identification and polymorphism of Plasmodium vivax RBP-1 peptides which bind specifically to reticulocytes.

Plasmodium vivax merozoite preferentially invades reticulocytes probably using PvRBP-1 as ligand. One hundred and ninety-five, 15-mer peptides has been synthesised from PvRBP-1 sequence; tested in reticulocyte- or erythrocyte-binding assays. Twenty-five peptides (K(d)=76-380 nM) specifically defined four reticulocyte-binding regions.

Desiccation resistance in two species of Drosophila.

Three populations of Drosophila pseudoobscura, each one represented by 12 isofemale lines, and one laboratory strain of D. melanogaster were tested for desiccation resistance at two time periods. Except in the case of one population of D.
