Gonadotropins in the Russian Sturgeon: Their Role in Steroid Secretion and the Effect of Hormonal Treatment on Their Secretion. [PDF]

, 2016
In the reproduction process of male and female fish, pituitary derived gonadotropins (GTHs) play a key role. To be able to specifically investigate certain functions of Luteinizing (LH) and Follicle stimulating hormone (FSH) in Russian sturgeon ...

Purification and characterization of human chorionic gonadotropin

FEBS Letters, 1971
Several investigators [2-71 have previously attempted to purify human chorionic gonadotropin (HCG). These methods proved to be either too time consuming, not reproducible, or limited to small quantities. In addition, these purified products are difficult to compare because of differences in the methodology of biological and physico-chemical ...

Atomic Force Microscopy Reveals Differences In Mechanical Properties Linked To Cortical Structure In Mouse And Human Oocytes

Small, EarlyView.
Using Atomic Force Microscopy, the link between oocyte mechanical properties and actin cortex organization is investigated. In mouse oocytes, a thin actin cortex results in stiffer oocytes, while a thicker cortex leads to softer ones. Maternal age affects oocyte mechanics by altering cortex structure.

Human Chorionic Gonadotropin Influences Systemic Autoimmune Responses

Frontiers in Endocrinology, 2018
Immunopathological outcomes in Systemic Lupus Erythematosus (SLE; or lupus) are believed to be autoantibody-mediated. Conditions which promote a Th2 skew (such as pregnancy) should encourage antibody production, worsening antibody-mediated diseases while

Mean surface shape of a human placenta [PDF]

arXiv, 2008
The chorionic plate (or "fetal surface") of the human placenta is drawn as round, with the umbilical cord inserted roughly at the center, but variability of this shape is common. The average shape of the chorionic plate has never been established. The goal of this work is to measure the average shape in a birth cohort.

Human amniotic fluid glycoproteins expressing sialyl Lewis carbohydrate antigens stimulate progesterone production in human trophoblasts in vitro [PDF]

, 2004
Background: Progesterone is thought to mediate immune modulator effects by regulating uterine responsiveness. The aim of the study was to clarify the effect of transferrin and glycodelin A (former name PP14) as sialyl Lewis X-expressing glycoproteins on ...

ENT‐1‐Targeted Polymersomes to Enhance the Efficacy of Methotrexate in Choriocarcinoma Treatment

Small Science, EarlyView.
ENT‐1‐targeted stimuli‐responsive polymersomes enhance the delivery and release of MTX, as demonstrated in choriocarcinoma tumors mouse model. These targeted nanocarriers improve tumor uptake and efficiently release the drug within the tumor, highlighting their potential for enhanced chemotherapy in choriocarcinoma treatment.

Abnormality of the placental vasculature affects placental thickness [PDF]

arXiv, 2011
Our empirical modeling suggests that deformation of placental vascular growth is associated with abnormal placental chorionic surface shape. Altered chorionic surface shape is associated with lowered placental functional efficiency. We hypothesize that placentas with deformed chorionic surface vascular trees and reduced functional efficiency also have ...

Some of the oxidation-reduction properties of the chorionic gonadotropic hormone [PDF]

, 1941
Gurin, Bachman, and Wilson (1-3) have recently made important contributions to our knowledge of the chemical nature of the gonadotropic hormone of pregnancy urine.
