William Montagna’s research while affiliated with Mount Sinai Hospital and other places

... Montagna, with a Ph.D in Zoology, was affiliated to the Brown University of Rhode Island in 1950s, and later at the Oregon Regional Primate Research Center. [22][23][24][25] Table 1 summarizes the histological data generated by Montagna and his colleagues on the Montgomery glands in adolescent girls and women. The merit in these studies [22][23][24] was, that the surgical specimens were collected few hours after accidental deaths of subjects, and can be assumed to be of normal configuration. ...

... If possible, patients' ability to perspirate was investigated by quantification of pilocarpine-induced sweating on the forearms (in an area of 57 mm 2 ) using the Wescor 3700 device (Wescor, Logan, United States) and determination of palmar sweat duct densities via reflectance confocal laser-scanning microscopy with the VivaScope 1,500 (Caliber Imaging & Diagnostics, New York, United States), both as described before (Burger et al., 2014). The total number of sweat ducts is determined early in life, which means that the sweat gland density decreases with an increasing skin surface (adults have about 300-500/cm 2 , while newborns normally show more than 1,000/ cm 2 ; Montagna and Parakkal, 1974). ...

... Sebaceous glands are not a type of sweat gland but worth mentioning here since their secretions can impact the composition of sweat collected at the skin surface [25]. Sebaceous glands, first described by Eichorn in 1826 [26], are associated with hair follicles and present over much of the body surface but particularly the scalp, forehead, face, and anogenital area [26,27]. They are absent on the palms of hands and soles of the feet [26]. ...

... The lack of consensus and sparse information on breast tissue material and mechanical properties may have contributed to the variability seen in the experimental methodologies, demographics, and specimens [14,15]. Breast tissue is located internally, whereas skin is the first layer, which is located externally [7,[16][17][18]. Breast stability and behavior are dependent on its internal mechanical properties and applied external forces. ...

... In addition, a selective modulation of the regional cortical excitability, an enlargement of the receptive fields, and the effects of cortical deafferentation could be taken into account in an attempt to explain a C-LEP generator preservation or reorganization44454647 . Moreover, we could speculate about a strong C-LEP network stability in reason of an older phylogenetic origin [48], and a functional switch to a fixed " in-parallel " or " in-series " processing of nociceptive inputs [49]. The main limitations in our study are to be considered the small number of EEG channels we employed (since we were not able to use a full-EEG cap), and the non-homogeneous gender and age matching of our sample. ...

... Normal development and function of the sebaceous gland also appears to be very important for correct hair development and cycling. The hair follicle is considered as a miniorgan living in the context of the ''pilo-sebaceous'' unit, which is composed of hair follicle, sebaceous gland, and pilo-erector muscle (Montagna and Parakkal, 1974 ). Abnormal sebaceous gland function within this context has been clearly associated with hair loss in several animal models for alopecia (Gates and Karasek, 1965; Gates et al., 1969; Williams and Stenn, 1994; Stenn, 2001; Porter et al., 2002). ...

... The apocrine gland is a second type of sweat gland, which was first recognized by Krause in 1844 and later named by Schiefferdecker in 1922 [20,21]. Apocrine sweat glands are located primarily in the axilla, breasts, face, scalp, and the perineum [21,22]. ...
