A microfibril is a very fine fibril, or fiber-like strand, consisting of glycoproteins and cellulose. It is usually, but not always, used as a general term in describing the structure of protein fiber, e.g. hair and sperm tail.
Cellulose chains are observed to align in overlapping parallel arrays, with the similar polarity forming a cellulose microfibril. In plants, these cellulose microfibrils arrange themselves into layers, formally known as lamellae, and are stabilized in the cell wall by surface, long cross-linking glycan molecules. Glycan molecules increase the ...
A diagram of the structure of a myofibril (consisting of many myofilaments in parallel, and sarcomeres in series) Sliding filament model of muscle contraction. The myosin heads form cross bridges with the actin myofilaments; this is where they carry out a 'rowing' action along the actin. When the muscle fibre is relaxed (before contraction ...
Blood culture bottle: Sodium polyanethol sulfonate (anticoagulant) and growth media for microorganisms: Usually drawn first for minimal risk of contamination. [1] Two bottles are typically collected in one blood draw; one for aerobic organisms and one for anaerobic organisms. [2] Blue ("light blue") Sodium citrate (weak calcium chelator ...
CFU-GEMM is a colony forming unit that generates myeloid cells.CFU-GEMM cells are the oligopotential progenitor cells [1] [2] for myeloid cells; they are thus also called common myeloid progenitor cells or myeloid stem cells.
Hemoglobin is an iron-containing protein that gives red blood cells their color and facilitates transportation of oxygen from the lungs to tissues and carbon dioxide from tissues to the lungs to be exhaled. [3] Red blood cells are the most abundant cell in the blood, accounting for about 40-45% of its volume.
Grey's Anatomy stars Jessica Capshaw and Camilla Luddington, co-hosts of iHeartRadio'sCall It What It Is podcast, get to handpick the guests that come on their show so they don't have rude ...
CFU-E is a stage of erythroid development between the BFU-E stage and the pro-erythroblast stage. CFU-E colony assay is designed to detect how many colony-forming-units of erythroid lineage there are in a hematopoietic tissue (bone marrow, spleen, or fetal liver), which may be reflective of the organism’s demand for oxygen delivery to the tissues or a hematopoietic disorder.
