Comparison of urinary prolactin and serum/urine prolactin ratio in hyperprolactinemic and macroprolactinemic patients [PDF]

BMC Endocrine Disorders
Background Biologically, the monomeric form of prolactin is the most active. In measurement methods, all forms of prolactin are included in the assay; therefore, the presence of macroprolactin, causes a false increase in prolactin and misdiagnosis of ...

Abnormal prolactin secretion is associated with changes in metabolic health biomarkers in acyclic female African elephants (Loxodonta africana)

Theriogenology Wild, 2023
Circulating prolactin aberrations (chronically high or low concentrations) have been shown to have strong associations with ovarian dysfunction in African female elephants.

A long-lasting prolactin stimulates galactopoiesis in mice [PDF]

iScience
Summary: Prolactin is the main hormonal driver of mammalian lactation. To sustain milk production, basal prolactin levels must remain elevated compared to nonpregnant states.

Prolactin at moderately increased levels confers a neuroprotective effect in non-secreting pituitary macroadenomas.

PLoS ONE, 2022
ContextProlactin, a hormone synthesized by the anterior pituitary gland demonstrates promise as a neuroprotective agent, however, its role in humans and in vivo during injury is not fully understood.ObjectiveTo investigate whether elevated levels of ...

Utility of Cannulated Prolactin to Exclude Stress Hyperprolactinemia in Patients with Persistent Mild Hyperprolactinemia

Clinical Medicine Insights: Endocrinology and Diabetes, 2021
Background: Stress-induced hyperprolactinemia can be difficult to differentiate from true hyperprolactinema and may result in patients having unnecessary investigations and imaging.

Cortisol levels are positively associated with pup-feeding rates in male meerkats [PDF]

, 2006
In societies of cooperative vertebrates, individual differences in contributions to offspring care are commonly substantial. Recent attempts to explain the causes of this variation have focused on correlations between contributions to care and the ...

Gender-specific reference intervals for serum prolactin concentrations before and after precipitation by polyethylene glycol

Proceedings of Singapore Healthcare, 2022
Prolactin, a hormone secreted by the anterior pituitary, exists in three major forms in circulation. The macroprolactin form is biologically inactive but contributes to elevated serum prolactin concentrations.

Metode pembuatan antiprolaktin pada hewan coba kambing lokal sebagai penghambat proses rontok bulu pada ayam arab petelur

Journal of Biological Researches, 2012
Anti-prolactin has a specific activity against prolactin. It neutralizes prolactin action in circulation. The effect of such neutralization is the inhibition of feather fall off process, so that hens may be able to produce eggs again. Anti-prolactin can
