Determination of Androgen Bioactivity by an In Vitro Assay During Pubertal Transition in Healthy Boys

Clinical Endocrinology, EarlyView.
ABSTRACT Objective To describe the bioactivity of circulating androgens during pubertal transition as determined by an in vitro bioassay assessing androgen receptor (AR) activation, and to compare these findings with circulating concentrations of total testosterone (total T) measured by LC‐MS/MS.

Delayed Bone Maturation and Extended Growth Phase as Distinctive Features of 17α‐Hydroxylase/17,20‐Lyase Deficiency: A Retro‐Prospective Study of a Large Patient Cohort

Clinical Endocrinology, EarlyView.
ABSTRACT Introduction Worldwide, combined 17‐hydroxylase/17,20‐lyase deficiency (CYP17D) is a rare form of congenital adrenal hyperplasia, but it is the second most prevalent type in Brazil. An absence of sexual differentiation and hypergonadotropic hypogonadism arise from a reduction in the usual pattern of sex steroid formation in the adrenals and ...

Society for Endocrinology Clinical Practice Guideline for the Evaluation of Androgen Excess in Women

Clinical Endocrinology, EarlyView.
ABSTRACT Context Androgen excess is common in women and refers to clinical or biochemical evidence of elevated androgenic steroids such as testosterone. It is associated with underlying polycystic ovary syndrome in the majority of cases. However severe androgen excess is less common and may indicate the presence of underlying adrenal or ovarian ...

The Impact of Metformin on Plasma Prolactin Levels in Antipsychotics‐Treated Men With Hyperprolactinemia and Early‐Onset Androgenic Alopecia

Clinical Endocrinology, EarlyView.
ABSTRACT Objective Metformin decreases elevated levels of pituitary hormones. Little is known about the association between the reproductive axis and hormonal effects of this drug. The purpose of our study was to investigate whether activity of the hypothalamic‐pituitary‐gonadal axis determines metformin action on prolactin levels in men with prolactin

Combining Procalcitonin and Calcitonin for the Diagnosis of Medullary Thyroid Cancer: A Two‐Step Approach

Clinical Endocrinology, EarlyView.
ABSTRACT Objective Calcitonin (CT) represents the most important biochemical marker of medullary thyroid cancer (MTC), but has certain limits. Procalcitonin (ProCT) has been recognized as an alternative or additional marker for MTC. The aim of the study is to evaluate prospectively the role of ProCT combined with CT in the identification of MTC ...

Multi‐Omics Reveal the Metabolic Changes in Cumulus Cells During Aging

Cell Proliferation, EarlyView.
Fatty acid β‐oxidation was elevated in cumulus cells from older mice. Tryptophan metabolism in aged cumulus cells was active. Supplementing with 5‐HT could mitigate aging damage in oocytes. ABSTRACT Maternal age has been reported to impair oocyte quality.

Decoding the Molecular Landscape of Prepubertal Oocyte Maturation: GTPBP4 as a Key Driver of In Vitro Developmental Competence

Cell Proliferation, EarlyView.
Transcriptional and translational characteristics during goat oocyte maturation and identification of key factors, including GTPBP4, for prepubertal goat oocyte maturation. ABSTRACT The intricate mechanisms driving oocyte maturation remain only partially understood, especially within the domains of domestic animal reproduction and translational ...
