Organelles of the secretory pathway involved in the secretion of exoenzymes. An exoenzyme, or extracellular enzyme, is an enzyme that is secreted by a cell and functions outside that cell. Exoenzymes are produced by both prokaryotic and eukaryotic cells and have been shown to be a crucial component of many biological processes.
Exoenzymes also aid digestion in the guts of ruminants, [6] termites, [7] humans and herbivores. By hydrolyzing plant cell wall polymers, microbes release energy that has the potential to be used by humans as biofuel. [8] Other human uses include waste water treatment, [9] composting [10] and bioethanol production. [11]
Hair is a protein filament that grows from follicles found in the dermis.Hair is one of the defining characteristics of mammals.The human body, apart from areas of glabrous skin, is covered in follicles which produce thick terminal and fine vellus hair.
[citation needed] Fungal folliculitis is a rare hair follicle infection induced overwhelmingly by Trichophyton, which can be spread zoonotically. [ 6 ] [ 7 ] The fungi can easily spread to other areas of the body as well and to the host's home environs (socks, shoes, clothes, showers, bathtubs, counters, floors, carpets, etc.).
Your hair growth cycle involves three different phases, and each hair follicle is at a different point in the cycle at any given time. These phases include the anagen phase (or growth phase), the ...
More specifically, the topically treated mice demonstrated a 50% reduction in gray hair—80% of untreated mice's hair turned gray while only 40% of treated mice's did—and a 25 to 30% reduction ...
Almost complete sequences of Mycobacterium leprae from medieval skeletons with osteological lesions suggestive of leprosy from different Europe geographic origins were obtained using DNA capture techniques and high-throughput sequencing. Ancient sequences were compared with those of modern strains from biopsies of leprosy patients representing ...
Hair growth on the forehead is suppressed in a bilateral pair of periorbital fields. Without a widow's peak, these fields join in the middle of the forehead so as to give a hairline that runs straight across. A widow's peak results when the point of intersection on the forehead of the upper perimeters of these fields is lower than usual.
