A Multiepitope‐Based Lateral Flow Assay for Leprosy Antibodies

Analysis &Sensing, EarlyView.
An innovative lateral flow assay for leprosy diagnosis is based on gold nanoparticles and synthetic Mycobacterium leprae epitopes conjugated to keyhole limpet hemocyanin protein to enhance antibody detection. This strategy provides a rapid, accurate, and low‐cost approach for resource‐limited settings, enabling the early detection of infection. Leprosy

Mapping molluscan endocrinology: a systematic and critical appraisal

Biological Reviews, EarlyView.
ABSTRACT Historically, a vertebrate‐centric paradigm has framed our interpretation of molluscan endocrinology, with considerable research focusing on vertebrate‐type steroid hormones (e.g. oestrogens, testosterone). However, contradictory evidence on the occurrence of vertebrate‐type steroid hormones in molluscan tissues, and a lack of the specific ...

Role of pituitary adenylate cyclase‐activating polypeptide in modulating hypothalamic‐pituitary system

Reproductive Medicine and Biology, 2018
Background Pituitary adenylate cyclase‐activating polypeptide (PACAP) is a multifunctional peptide that is isolated and identified from the ovine hypothalamus, whose effects and mechanisms have been elucidated in numerous studies.

Pubertal Development in Girls with Beta Thalassaemia and Assessment of the Adequacy of Chelation Therapy: A Quasi-experimental Study [PDF]

Journal of Clinical and Diagnostic Research
Introduction: Beta thalassaemia is the most prevalent hereditary autosomal disorder, significantly impacting endocrine function during pubertal development. The pathology is rooted in the excessive deposition of iron in vital organs.

Molecular Mechanisms of Gonadotropin-Releasing Hormone Signaling: Integrating Cyclic Nucleotides into the Network

Frontiers in Endocrinology, 2013
Gonadotropin-releasing hormone (GnRH) is the primary regulator of mammalian reproductive function in both males and females. It acts via G-protein coupled receptors on gonadotropes to stimulate synthesis and secretion of the gonadotropin hormones ...

The mitochondrial DNA copy number and ovary‐related reproductive disorders: A bidirectional two‐sample Mendelian randomization study

International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 112-120, April 2025.
Abstract Objective In the present study, a bidirectional two‐sample Mendelian randomization approach was utilized to explore potential causal relationships between mitochondrial DNA copy number (mtDNA‐CN) and ovary‐related reproductive disorders (ORRDs), including ovarian dysfunction, ovarian cyst, polycystic ovary syndrome (PCOS), premature ovarian ...

Neuroendocrine regulation of gonadotropin secretion in seasonally breeding birds

Frontiers in Neuroscience, 2013
Seasonally breeding birds detect environmental signals, such as light, temperature, food availability, and presence of mates to time reproduction. Hypothalamic neurons integrate external and internal signals, and regulate reproduction by releasing ...

A review of the impact of micro‐ and nanoplastics on female reproduction: What we know and gaps in knowledge

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Micro‐and nanoplastics (MNPs) are breakdown products of plastics, and humans are exposed to these particles through air, water, food, and soil. There is a growing concern that human exposure to MNPs negatively impacts health. In this review we will discuss the potential health impact of MNPs on ovarian function and the hypothalamic–pituitary ...

Discovery of Potent Kisspeptin Antagonists Delineate Physiological Mechanisms of Gonadotropin Regulation

Journal of Neuroscience, 2009
Neurons that produce gonadotropin-releasing hormone (GnRH) are the final common pathway by which the brain regulates reproduction. GnRH neurons are regulated by an afferent network of kisspeptin-producing neurons. Kisspeptin binds to its cognate receptor
