Membrane progesterone receptor γ (paqr5b) is essential for the formation of neurons in the zebrafish olfactory rosette.

Paqr5b is a gene encoding membrane progesterone receptor γ (mPRγ), which is one of five mPR subtypes. Paqr5b belongs to the progestin and adipoQ receptor (PAQR) family, which consists of 11 genes. To elucidate the physiological functions of the mPR subtypes, we established gene knockout (KO) zebrafish strains by genetically editing seven paqr genes and analyzed their phenotypes.

The quaternary compound copper manganese tin sulfide CuMnSnS is a potential absorber semiconductor material for fabricating thin film solar cells (TFSC) thanks to their promising optoelectronic parameters. This article numerically investigated the performance of CuMnSnS (CMTS)-based TFSC without and with tin sulphide (SnS) back surface field (BSF) thin-film layer.

Performance Enhancement of an MoS-Based Heterojunction Solar Cell with an InTe Back Surface Field: A Numerical Simulation Approach.

Researchers are currently showing interest in molybdenum disulfide (MoS)-based solar cells due to their remarkable semiconducting characteristics. The incompatibility of the band structures at the BSF/absorber and absorber/buffer interfaces, as well as carrier recombination at the rear and front metal contacts, prevents the expected result from being achieved. The main purpose of this work is to enhance the performance of the newly proposed Al/ITO/TiO/MoS/InTe/Ni solar cell and investigate the impacts of the InTe BSF and TiO buffer layer on the performance parameters of open-circuit voltage ( ), short-circuit current density ( ), fill factor (FF), and power conversion efficiency (PCE).

Concurrent investigation of antimony chalcogenide (SbSe and SbS)-based solar cells with a potential WS electron transport layer.

Antimony (Sb) chalcogenides such as antimony selenide (SbSe) and antimony sulfide (SbS) have distinct properties to be used as absorber semiconductors for harnessing solar energy including high absorption coefficient, tunable bandgap, low toxicity, phase stability.

The adverse effects on reproductive factors, such as gonadal activity, fertility, hatching rate and malformation of embryo caused by the dietary administration on initial generation (F0) male and female zebrafish were continued until third filial (F3) generation. In this study, we examined how much amount of BPA contained in the diet was taken up by the zebrafish.

An agonist for membrane progestin receptor (mPR) induces oocyte maturation and ovulation in zebrafish in vivo.

The maturation and ovulation of fish oocytes are well-characterized biological processes induced by progestins via coordination of nongenomic actions and genomic actions.

By this in vivo assay, the potencies of chemicals in inducing or preventing oocyte maturation and ovulation can be evaluated.

Two-Step Mechanism of Cyclin B Degradation Initiated by Proteolytic Cleavage with the 26 S Proteasome in Fish.

To complete meiosis II, cyclin B is degraded in a short period by the inactivation of M-phase promoting factor (MPF). Previously, we showed that the destruction of cyclin B was initiated by the ubiquitin-independent proteolytic activity of the 26 S proteasome through an initial cut in the N-terminus of cyclin (at K57 in the case of goldfish cyclin B). We hypothesized that this cut allows cyclin to be ubiquitinated for further destruction by the ubiquitin-dependent proteolytic pathway, which leads to MPF inactivation.
