On the Hardness of Problems Involving Negator Relationships in an Artificial Hormone System [PDF]
arXiv, 2020 The Artificial Hormone System (AHS) is a self-organizing middleware to allocate tasks in a distributed system. We extended it by so-called negator hormones to enable conditional task structures. However, this extension increases the computational complexity of seemingly simple decision problems in the system: In [1] and [2], we defined the problems ...

Human Luteinizing Hormone and Chorionic Gonadotropin Display Biased Agonism at the LH and LH/CG Receptors [PDF]
Scientific Reports, 7(940) (2017), 2018 Human luteinizing hormone (LH) and chorionic gonadotropin (hCG) have been considered biologically equivalent because of their structural similarities and their binding to the same receptor; the LH/CGR. However, accumulating evidence suggest that LH/CGR differentially responds to the two hormones triggering differential intracellular signaling and ...

PACAP induces FSHβ gene expression via EPAC. [PDF]
, 2019 Gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), are heterodimers of a common α subunit and unique β subunits. Regulation of their levels, primarily by GnRH, is critical for reproductive function.

Development of Gonadotropin-Releasing Hormone Secretion and Pituitary Response
Journal of Neuroscience, 2014 Acquisition of a mature pattern of gonadotropin-releasing hormone (GnRH) secretion from the CNS is a hallmark of the pubertal process. Little is known about GnRH release during sexual maturation, but it is assumed to be minimal before later stages of ...

Biology and Management of Male‐Bodied Athletes in Elite Female Sports
Drug Testing and Analysis, EarlyView.Graphical representation of the relationships of transgender and XY DSDF as male‐bodied athletes along the binary dimensions of biological sex. ABSTRACT The physical advantages in elite power sports that allow men to surpass women are derived from the experience of male puberty.

Different clinical courses of central precocious girls according to their age at presentation and treatment [PDF]
Annals of Pediatric Endocrinology & Metabolism, 2013 PurposeThe progressivity of central precocious puberty (CPP) seems to depend on the age at presentation. We evaluated the clinical courses of CPP girls according to their age at initiation of treatment.MethodsOne hundred thirty five girls with CPP ...

Expression of three GnRH receptors in specific tissues in male and female sea lampreys Petromyzon marinus at three distinct life stages [PDF]
, 2013 Two recently cloned gonadotropin-releasing hormone (GnRH) receptors (lamprey GnRH-R-2 and lamprey GnRH-R-3) along with lamprey (l) GnRH-R-1 were shown to share similar structural features and amino acid motifs common to other vertebrate receptors.
