Influence of Autophagy Induction after Hormone Treatment on Oocytes Maturation of Porcine

Journal of Animal Reproduction and Biotechnology, 2018
Here, we evaluated the mode of programmed cell death during porcine oocyte maturation by comparing the two major pathways associated with programmed cell death, apoptosis (type I), and autophagy (type II).

Control of Polarization and Polar Helicity in BiFeO3 by Epitaxial Strain and Interfacial Chemistry

Advanced Functional Materials, EarlyView.
In BiFeO3 thin films, the interplay of interfacial chemistry, electrostatics, and epitaxial strain is engineered to stabilize homohelicity in polarization textures at the domain scale. The synergistic use of a Bi2O2‐terminated Aurivillius buffer layer and a highly anisotropic compressive epitaxial strain offers new routes to control the polar‐texture ...

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.

Synthesis and biological properties of [Leu-6]-LH-RH and [D-leu-6,desGly-NH 210]-LH-RH ethylamide [PDF]

, 1974
[Leu 6,desGly-NH 2 10]-LH-RH ethylamide and [Leu 6]-LH-RH, two analogs of LH-RH, were prepared by the solid phase method. LH- and FSH-releasing activity of these peptides was assayed against LH-RH by subcutaneous administration in immature male rats ...

Mechanism of LH Release with Synthetic LH-RH

Folia Endocrinologica Japonica, 1976
In a 2-part study 15 female baboons were injected with 100 mcg luteinizing hormone-releasing hormone (LH-RH) sc in the early follicular and early luteal phases to examine the mechanism of LH release. Assays of blood samples after the luteal-phase injection showed a peak plasma level of LH-RH at 4 minutes with a sharp then slow decline.

Swelling‐Programmed Topographical Guidance for Dynamic Spheroid Self‐Assembly via a Mechanochemical Hydrogel Niche

Advanced Functional Materials, EarlyView.
A swelling‐programmed micropatterned hydrogel guides adherent cells through a controlled transition from cell–matrix anchoring to cadherin‐mediated cell–cell compaction, enabling rapid assembly of high‐viability spheroids with defined size and morphology.

X‐Functionality–Driven Photocatalytic Hydrogen Evolution in 2D 4‐X‐PEA2SnI4 Perovskites

Advanced Functional Materials, EarlyView.
We report a water‐based synthesis of 2D 4‐X‐PEA2SnI4 perovskite microcrystals with prominent photocatalytic (PC) activity for H2 production. The synergy between organic functionalization and HI‐derived iodide scavenges holes suppress octahedral distortion, and favor electron accumulation, enabling a PC H2 evolution ∼20 µmol·g−1 and long‐term stability ...

LH‐RH Agonists and Antagonists [PDF]

, 1980
Large doses of stimulatory analogues of luteinizing hormone‐releasing hormone (LH‐RH) caused paradoxical anti‐fertility effects. These effects are being utilized for the possible development of contraceptive methods. Several inhibitory analogues of LH‐RH
