Regulation of testicular LH receptors by homologous hormone: studies on receptor occupancy and receptor loss

, 1977
A method is described which makes use of 4M MgCl2 to dissociate the testicular luteinizing hormone-receptor complex without altering either the binding capacity or binding affinity of the receptor.

Intermediate Resistive State in Wafer‐Scale Vertical MoS2 Memristors Through Lateral Silver Filament Growth for Artificial Synapse Applications

Advanced Functional Materials, EarlyView.
In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

Fish FSH receptors bind LH: how to make the human FSH receptor to be more fishy?

, 2005
In mammals, the interactions between glycoprotein hormones and their cognate receptors are highly specific; unintended cross-reactivity under normal physiological conditions has not been observed.

Exploring an Alternative to mRNA Vaccine Cold Chain Storage: MRNA‐Lipid Nanoparticle Stability When Dried in a Polymer Matrix

Advanced Functional Materials, EarlyView.
The nanostructure, size, and function of mRNA‐loaded lipid nanoparticles are evaluated before drying, within polymer microneedles, and after rehydration. The results reveal the polymer and LNP loadings required to recover nanostructure and preserve the delivery performance in dry‐state formulations.

Expression of Relaxin Family Peptide Receptors 1 and 3 in the Ovarian Follicle of Japanese Quail

The Journal of Poultry Science
In our previous studies, we demonstrated that the primary source of relaxin 3 (RLN3) in Japanese quail is ovarian granulosa cells. Although several relaxin family peptide (RXFP) receptors have been sequenced, the intricacies of these receptors in avian ...

Calcitonin Directly Inhibits Luteinizing Hormone-Stimulated Progesterone Production in Granulosa Cells of the Largest Follicle of Hen

The Journal of Poultry Science, 2010
The present study was performed to demonstrate the presence of receptors for avian calcitonin (cCT) in ovarian granulosa cells of the largest follicle of laying hens and to determine the effect of cCT on LH-stimulated P4 production.

Immunohistochemical demonstration of LH/CG receptors in non-neoplastic human adrenal cortex and adrenocortical tumors

, 2019
Introduction. Numerous data indicate that luteinizing hormone and/or chorionic gonadotropin (LH/CG) exert direct actions on the adrenal cortex and are involved in the adrenal pathology.

Long‐Range Coordination Environment Modulates Single‐Atom Local States and Systemic Impact on CO2 Photoconversion

Advanced Functional Materials, EarlyView.
Terminal groups on Cu porphyrins modulate the electronic states of single‐atom Cu centers through a long‐range electronic effect, without altering the Cu coordination geometry. Meanwhile, a multi‐descriptor framework is established that incorporates porphyrin regulation, hybrid catalyst properties, and CO2 photoreduction capabilities.

Theca Cell INSL3 and Steroids Together Orchestrate the Growing Bovine Antral Follicle

Frontiers in Physiology, 2017
Insulin-like peptide 3 (INSL3) and its specific receptor RXFP2 are both expressed by theca interna cells of the growing antral follicle where they form an essential regulatory element in the production of the steroid precursor androstenedione.
