thegametemembrane adhesion process that serves as a docking step prior to fusion may involves the sperm inner acrosomal membrane, which is only exposed at the time of the acrosome reaction (10,152). Another possible mechanism involves theautocrine effectsdue to release of acrosomal hormones or ...
Hormonal changes: When teens go through puberty, they see an increase in androgen hormones that enlarge sebaceous glands and cause them to produce more sebum. Hormonal changes linked to acne can also occur later in life. They are especially common in women and may be linked ...
根据第二段In the lab,the researchers first take cells from the leaves of a young plant.These cells are cultured in liquid medium for two days,then moved to another medium which contains nutrients and two different hormones.By adjusting the hormone levels,the researchers can tun...

Hormone-receptor positive breast cancers are so-called because the cancer cells have receptors for the hormones progesterone or estrogen. Molecules of estrogen fit these receptors like a lock and key, feeding the cancer and helping it grow. Aromatase inhibitors work by blocking the production of ...
hormones peptide tyrosine tyrosine (PYY) and glucagon-like peptide (GLP)-1. Studies in rabbits and rats have shown that SFCAs increase the production of PYY and GLP-1 (7,8). A recent study using human volunteers showed that the SCFA propionate, when delivered to the colon, increased the ...
Furthermore, the regulation of brain integrity and function must not be seen in isolation but as strongly dependent on feedback information (in the form of hormones, nutrients, metabolites and, of course, sensory neuron signalling) of the body periphery. In addition, mainly physico-mechanical ...
GCs act by binding to intracellular receptors of the target cell (glucocorticoid receptors; GRs). Genomic mechanisms derive from glucocorticoids binding to glucocorticoid receptors in the cytoplasm and the translocation of the GC/GR complex into the nucleus. In the nucleus, the GC/GR complex ...
In addition, the PS-NPs applied in the present study were synthesized without adding DEHP, which is a well-known endocrine disruptor that can alter reproductive hormones. Thus, caution should be taken when extrapolating this finding to plastic particles in a realistic environment, and further ...
