Molecular Investigations on Angiogenesis and Oxidative Stress in Roe Deer (Capreolus capreolus) Bucks' Testes Throughout the Reproductive Cycle

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Animals with seasonal reproductive cycles, as the Roe deer (Capreolus capreolus), have developed mechanisms to synchronize reproduction with the environmental cycle in order to optimize reproductive success through melatonin. Angiogenesis and oxidative stress are key processes in spermatogenesis, contributing to testicular remodeling and ...

Human Cyclophilins—An Emerging Class of Drug Targets

Medicinal Research Reviews, EarlyView.
ABSTRACT Cyclophilins are a family of enzymes with peptidyl‐prolyl isomerase activity found in all cells of all organisms. To date, 17 cyclophilin isoforms have been identified in the human body, participating in diverse biological processes. Consequently, cyclophilins have emerged as promising targets for drug development to address a wide array of ...

Prostate response to prolactin in sexually active male rats

Reproductive Biology and Endocrinology, 2006
Background The prostate is a key gland in the sexual physiology of male mammals. Its sensitivity to steroid hormones is widely known, but its response to prolactin is still poorly known. Previous studies have shown a correlation between sexual behaviour,

Mildly Higher Serum Prolactin Levels Are Directly Proportional to Cumulative Pregnancy Outcomes in in-vitro Fertilization/Intracytoplasmic Sperm Injection Cycles

Frontiers in Endocrinology, 2020
Hyperprolactinemia has long been considered detrimental to fertility due to irregularity of ovulation. Whether mild hyperprolactinemia should be corrected before initiating an in-vitro fertilization/intracytoplasmic sperm injection cycle (IVF/ICSI) has ...

Multiple eumenorrheic cycles are necessary to observe a significant increase in estrogen exposure and ovulation in exercising women with functional hypothalamic oligo/amenorrhea undergoing a nutritional intervention: Insights from the REFUEL study

PM&R, EarlyView.
Abstract Background Due to consequences of energy‐related oligo‐/amenorrhea (Oligo/Amen) among exercising females, recovery of menses (ROM) is a priority. ROM is inconsistently defined and rarely reported with reproductive hormone (estrogen, progesterone) data, making it difficult to know when females achieve adequate recovery. Objective The purpose of

Plasma Proteomics Analysis Identifying IGFBP2 as a Potential Diagnostic Biomarker for Laryngeal Squamous Cell Carcinoma

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective Currently, there are no blood biomarkers available for the early diagnosis of laryngeal squamous cell carcinoma (LSCC). The objective of this study was to search for potential plasma biomarkers for the diagnosis of LSCC. Methods Plasma samples were taken from patients with LSCC and healthy controls for proteomic analysis.

Determination of Prolactin in Canine Saliva: Is It Possible to Use a Commercial ELISA Kit?

Animals, 2019
Prolactin has been reported to be a remarkable index of stress response, both acute and chronic, in several species. The use of biological matrixes other than blood is receiving increasing interest in the study of hormones, due to the lower invasiveness ...

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

Andrology, 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 ...

Low testosterone in primary infertile men is associated with a history of maternal obesity during pregnancy: Findings from a cross‐sectional study

Andrology, EarlyView.
Abstract Background Maternal obesity increases offspring obesity risk, but limited data exist on its association with reproductive hormones in infertile males. Objectives To investigate the impact of maternal obesity during pregnancy on total testosterone levels in primary infertile men.
