BACKGROUND The present study aimed to evaluate the efficacy of the hyaluronic acid (HA) binding assay in the selection of motile spermatozoa with normal morphology at high magnification (8400x). METHODS A total of 16592 prepared spermatozoa were selected and classified into two groups: Group I, spermatozoa which presented their head attached to an HA substance (HA-bound sperm), and Group II, ...
Hyaluronan (HA) has many functions in the extracellular milieu of normal and diseased tissues. Disease-associated HA accumulation has been shown to predict a worsened prognosis in cancer patients, with tumors having a high-extracellular HA content (HA-high) being more aggressive than their HA-low counterparts. HA-high tumor aggressiveness is derived from the specialized biomechanical and molecu...
Lipid raft microdomains are enriched in sphingomyelin and cholesterol and function as platforms for signal transduction and as the site of budding of several enveloped viruses, including influenza virus. The influenza virus hemagglutinin (HA) glycoprotein, which mediates both viral-cell attachment and membrane fusion, associates intrinsically with lipid rafts. Residues in the HA transmembrane (...
