Beta-HCG Secretion by a Pulmonary Choriocarcinoma in a Male Patient

Case Reports in Oncological Medicine
Background. Paraneoplastic secretion of beta-subunit of human chorionic gonadotropin (β-HCG) in pulmonary carcinoma is rare. Case Presentation. A 65-year-old man presented with bilateral gynaecomastia with abnormally high levels of β-hCG and elevated ...

Nanomaterial‐Based Optical Biosensors for SARS‐CoV‐2 Detection: A Retrospective of the Pandemic

Advanced Sensor Research, Volume 4, Issue 9, September 2025.
This review discusses nanomaterial‐based optical biosensors developed for or adapted to the detection of severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2). It concludes by providing a perspective on how lessons learned during the coronavirus disease of 2019 (COVID‐19) pandemic may be applied for future research on nanomaterial‐based ...

Mutations of gonadotropins and gonadotropin receptors: elucidating the physiology and pathophysiology of pituitary-gonadal function [PDF]

, 2000
The recent unraveling of structures of genes for the gonadotropin subunits and gonadotropin receptors has provided reproductive endocrinologists with new tools to study normal and pathological functions of the hypothalamic ...

Revisiting the expression and function of follicle-stimulation hormone receptor in human umbilical vein endothelial cells [PDF]

, 2016
Expression of follicle-stimulation hormone receptor (FSHR) is confined to gonads and at low levels to some extragonadal tissues like human umbilical vein endothelial cells (HUVEC). FSH-FSHR signaling was shown to promote HUVEC angiogenesis and thereafter

Ectopic Pregnancy In Previously Infertile Women Subsequent Pregnancy Outcome After Laparoscopic Management [PDF]

Al Ameen Journal of Medical Sciences, 2009
Ectopic tubal pregnancy (ETP) is a major event in a woman's reproductive life particularly if it happens after treatment of infertility. It complicates infertility treatment and must be recognized early to simplify the treatment strategy, which must ...

Changes in the gene expression profiles of the brains of male European eels (Anguilla anguilla) during sexual maturation [PDF]

, 2014
Background: The vertebrate brain plays a critical role in the regulation of sexual maturation and reproduction by integrating environmental information with developmental and endocrine status. The European eel Anguilla anguilla is an important species in

METASTATIC TUMOR OF SPERMATIC CORD WITH ELEVATION OF SERUM HUMAN CHORIONIC GONADOTROPIN ^|^beta;-SUBUNIT

The Japanese Journal of Urology, 2005
A 62-year-old man was presented with a firm mass in right scrotum. Serum LDH and AFP were within normal range, but hCG-beta was elevated (2.3 ng/ml). Under the diagnosis of right testicular tumor, he underwent right radical orchiectomy. The specimen was a spermatic cord tumor with poorly differentiated adenocarcinoma.

Peripheral and central mechanisms involved in hormonal control of male and female reproduction [PDF]

, 2016
Reproduction involves the integration of hormonal signals acting across multiple systems togenerate a synchronized physiological output. A critical component of reproduction is the luteinizinghormone (LH) surge, which is mediated by estradiol (E2) and ...

Human Chorionic Gonadotropin .BETA.-Subunit Affects the Folding and Glycosylation of .ALPHA.-Cys Mutants.

Endocrine Journal, 2000
Human chorionic gonadotropin (hCG) is a member of a family of heterodimeric glycoprotein hormones that contain a common alpha-subunit but differ in their hormone-specific beta-subunits. Both subunits have five and six disulfide bonds, respectively, which consist of cystine knot structure.
