Purification and cultivation of human pituitary growth hormone secreting cells [PDF]

open access: yes
A multiphase study was conducted to examine the properties of growth hormone cells. Topics investigated included: (1) to determine if growth hormone (GH) cells contained within the rat pituitary gland can be separated from the other hormone producing ...

Spatial and temporal patterns of distribution of the gap junction protein connexin43 during mouse gastrulation and organogenesis [PDF]

open access: yes, 1992
Connexin43 (Cx43) is a member of the family of channel-forming proteins that make up the gap junction and are believed to provide pathways for cell-cell exchange of developmental signals.

Atavistic Genetic Expression Dissociation (AGED) During Aging: Meta‐Phylostratigraphic Evidence of Cellular and Tissue‐Level Phylogenetic Dissociation

open access: yesAging Cell, EarlyView.
Aging represents an atavistic over‐representation of differential expression in the most ancient genes and under‐representation in the evolutionary youngest genes for two multi‐tissue aging databases, and tissues covering skin, ovarian, immune, senescent and mesenchymal‐senescent cells. However, some tissues like brain and mesenchymal stem cells do not

Functional heterogeneity among cell types in the normal pituitary gland and in human and rat pituitary tumors. [PDF]

open access: yes, 1989
Hormone secretion by the anterior pituitary gland is under control of hypothalamic regulatory factorsjhormones (see chapter I.l) and peripheral hormones.

Testicular histopathology and its association with germ cell numbers, serum concentrations of reproductive hormones, and semen quality

open access: yesAndrology, EarlyView.
Abstract Background It is well‐established that spermatogenesis, semen quality, and reproductive hormones are interlinked. It is, however, less well‐described how various specific testicular histopathologies are linked to reproductive hormones and semen quality.

Kisspeptin as a test of hypothalamic dysfunction in pubertal and reproductive disorders

open access: yesAndrology, EarlyView.
Abstract The hypothalamic–pituitary–gonadal axis is regulated by the gonadotropin‐releasing hormone pulse generator in the hypothalamus. This is comprised of neurons that secrete kisspeptin in a pulsatile manner to stimulate the release of GnRH, and, in turn, downstream gonadotropins from the pituitary gland, and subsequently sex steroids and ...

Periodontitis and metabolic diseases (diabetes and obesity): Tackling multimorbidity

open access: yesPeriodontology 2000, EarlyView., 2023
Abstract Noncommunicable diseases (NCDs) are multifactorial, long‐term, chronic conditions that represent a burden to health‐care systems worldwide as they can only be controlled rather than cured; hence, they require long‐term care. With the exponential increase in NCDs, the occurrence of individuals presenting with more than one chronic disease is ...

Corticotroph Tumour Type Influences Clinical Behaviour in Patients With Nonfunctioning Pituitary Neuroendocrine Tumours. [PDF]

open access: yesEndocrinol Diabetes Metab
Harbouring a silent corticotroph tumour (SCT) compared to a silent gonadotroph tumour, being older at surgery and having a larger preoperative tumour were found to increase the likelihood of having postoperative pituitary failure in logistic regression analysis (n = 77).

The use of deidentified organ donor testes for research

open access: yesAndrology, EarlyView.
Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...
