Topic: Apocrine


  
  Berlinian Hypothesis Hermetic Diagnostics, Inc.   (Site not responding. Last check: 2007-10-20)
Apocrine sweat glands are located in the axilla (armpit), perigenital, perianal, and perimammary areas of the body.
Being concentrated in apocrine sweat means that the measured chemical concentration (nanograms/ml) of PSA in apocrine sweat is higher than the measured chemical concentration in the blood from which the apocrine sweat was made.
Apocrine sweat from control individuals would be separated by the same chromatography method and a subtraction of results would be done which would then identify the suspected biomarker protein from the cancer patients.

 Journal of Drugs in Dermatology: Bilateral facial apocrine chromhidrosis
Apocrine chromhidrosis was first described by Yonge in 1709 (1) and later attributed to lipofuscin pigments by Shelley and Hurley in 1954 (2).
Apocrine chromhidrosis usually manifests in puberty when these glands become functionally active and is unrelated to dietary, systemic, or metabolic alterations, gender, occupation, or geographical predisposition (1,2).
Under the microscope, the number of apocrine glands is variable and yellow-brown lipofuscin granules may be observed in the apical area of secretory cells with H and E stain.

 [No title]
The comparably large apocrine glands are found in limited areas, most notably the underarms and ano-genital skin, where they secrete (in remarkably small quantities) their sweat into the hair follicle.
Apocrine bromhidrosis never occurs before puberty, because the particular glands involved are not active in the pre-pubescent individual.
Apocrine sweat is the only natural product of the body which, when decomposed with bacteria, gives rise to the classic apocrine odor.

 Sebaceous Glands and the AAT
However, their claims that aquatic mammals lose their apocrine glands and sweat-cool via eccrine glands, and that human sebaceous glands are a waterproofing adaptation, are all contradicted by the facts.
The answer undoubtedly lies in her oft-stated belief that apocrine glands disappear in aquatic species (this is a cornerstone of her version of the aquatic ape hypothesis).
Apocrine glands discharge their contents and these must be replenished before they're used again, while eccrine glands can go on and on.

Limiting perspiration in localized areas associated with apocrine sweat is desirable from a social perspective.
Apocrine sweat is associated with odor because of the action of bacteria on components of the sweat.

 Apocrine carcinoma of the skin   (Site not responding. Last check: 2007-10-20)
Apocrine carcinomas of the skin are rare and incompletely studied neoplasms.
The most reliable histopathologic criteria for identifying apocrine skin carcinoma appear to be decapitation secretion, periodic acid-Schiff-positive diastase-resistant material in the cells or lumen, and immunoreactivity with gross cystic disease fluid protein 15.
Apocrine differentiation in skin tumors does not indicate an exclusive origin from the apocrine sweat glands; these neoplasms usually have an indolent clinical course.

 Body Odor Support
Eccrine glands are distributed over the entire skin surface and primarily are involved in thermoregulation via sweat production.In contrast, apocrine glands have a limited distribution, involving the axilla, genital skin, and breasts; apocrine elements also commonly are found in the periorbital and periauricular areas.
Apocrine glands have no thermoregulatory role but are responsible for characteristic pheromonic odor.
Excessive eccrine secretion may favor the spread of apocrine sweat and contribute further to bromhidrosis or, conversely, may cause a decrease in odor because the eccrine sweat dilutes the apocrine sweat.

 apocrine   (Site not responding. Last check: 2007-10-20)
A pungent, musky scent produced by dense concentrations of apocrine glands in the underarms, and by lesser concentrations in the face, scalp, ears, eyelids, genital area, and navel.
Usage: Many consider apocrine odor offensive (e.g., as a sign of poor grooming), and use deodorants to mask its smell.
Odorless until digested by bacteria, millions of possible smell combinations suggest that apocrine odor may be used to announce our personal identity, presence, and sexual moods.

 WSAVA 2001 - ADENOCARCINOMA OF APOCRINE GLANDS IN THE ANAL SAC IN A FEMALE DOG: A CASE REPORT
Adenocarcinomas of apocrine glands in the anal sac are even more uncommon in females, affecting specially bitches older than 9 years.
This report describes a case of adenocarcinoma of apocrine glands from the anal sac in a Cocker Spaniel bitch of 9 years old, brought to the Veterinary Hospital of the Methodist University of São Paulo due to the presence of a perianal bulk and symptoms such as polyuria and polydipsia.
By clinical examination, it was observed a tumor mass of approximately 10 cm of diameter in the left size of the perianal region, showing firm consistence, regular surface, local adherence and discreet sensibility.

 Location of gene for ear wax could increase understanding of apocrine-gland development
Ear wax is produced by the ceruminous apocrine gland (other apocrine glands being located in the breast and armpit).
Dry ear wax is associated with less-developed apocrine glands—therefore a gene coding for earwax could control development of apocrine glands and the nature of their secretory products.
From this, the investigators were able to identify the gene coding for ear wax as being located on the same area of chromosome 16 as the gene responsible for paroxysmal kinesigenic choreoathetosis.

Apocrine change or differentiation is characterized by cells that are larger than usual and have abundant, granular eosinophilic cytoplasm, distinct cell borders, and luminal apical blebbing.
Many researchers do not recognize apocrine carcinoma as a distinct clinicopathologic entity as most studies have found no significant differences in natural history and prognosis relative to regular infiltrating ductal carcinoma.
For the time being, therapy for apocrine carcinoma is identical to that for infiltrating ductal carcinoma (6).

The secretory coil of the ovine apocrine gland is composed predominantly of two cell types, secretory cells lining the lumen and myoepithelial cells adjacent to the basement membrane.
The glands synthesize a number of hormones and growth factor, but analysis of the functions of these molecules may be hampered by the mixing of apocrine and sebaceous secretions in the pilary canal.
