LaTiO nanosheets modified by Pt quantum dots for efficient NO removal avoiding NO secondary pollutant.

Two-dimensional LaTiO nanosheets with regular morphology and good dispersion were prepared by the hydrothermal method under a magnetic field. Zero-dimensional Pt quantum dots (Pt-QDs) were loaded on the LaTiO nanosheets. The electron-hole separation and carrier transfer in the Pt-loaded LaTiO nanosheets were significantly enhanced.

Direct observation of carrier migration in heterojunctions to discuss the p-n and direct Z-scheme heterojunctions.

Type II p-n heterojunction and direct Z-scheme heterojunction are identical staggered band alignments, but were reported ambiguously in many composite photocatalysts because their carriers migrate in opposite directions. In this research, metal oxides CuO, NiO and CoO-based heterojunctions with NaMgTiO(NMTO) were synthesized via a simple hydrothermal method. The CuO/NMTO heterojunction was demonstrated as a direct Z-scheme heterojunction, whereas the NiO/NMTO and CoO/NMTO heterojunctions showed type II p-n band alignment, distinguished by the direct observation of carrier migration under light illumination, and confirmed by the x-ray photoelectron spectroscopy, Mott-Schottky measurements, ultraviolet photoelectron spectra and capture experiments.

Development of novel KNiTiO nano bamboo leaves, microstructural characterization, double absorption, and photocatalytic removal of organic pollutant.

Novel KNiTiO (KNTO) nano bamboo leaves were prepared for the first time under a simple hydrothermal method with 3 M KOH at 320 °C over 80 min. Highly pure KNTO possessing layered structure was determined by X-ray diffraction (XRD) and high-resolution transmission electron microscope (HRTEM). Double absorption feature of KNTO semiconductor was revealed at band energies of 1.

The E3 Ubiquitin Ligase CRL4 Regulates Proliferation and Progression Through Meiosis in Chinese Mitten Crab Eriocheir sinensis.

The Cullin-RING E3s are multisubunit ubiquitin ligases composed of a scaffold protein known as Cullin, a RING finger protein that regulates diverse cellular pathways; however, their contribution to male gonad development, especially the spermatogenesis of the Chinese mitten crab (Eriocheir sinensis), is not well understood. We identified five evolutionarily conserved Cullins from the transcriptome and genome ofE. sinensis that are potentially involved in regulating male gonad development.

Profiling microRNAs in the testis during sexual maturation stages in Eriocheir sinensis.

MicroRNAs (miRNAs) have been implicated in several cellular processes of reproductive tissues through post-transcriptional regulation of protein coding genes. The presence of miRNAs, their expression patterns and processing machinery genes in different stages of testicular and ovarian cellular development have demonstrated the potential role of miRNAs in testicular and ovarian physiology. The Chinese mitten crab (Eriocheir sinensis) is one of the most important aquaculture species in China and has high commercial value as a food source.

ERK is involved in the process of acrosome reaction in vitro of the Chinese mitten crab, Eriocheir sinensis.

Mitogen-activated protein kinases (MAPKs), also termed extracellular signal-regulated kinases (ERKs), are cytoplasmic and nuclear serine/threonine kinases involved in signal transduction of several extracellular effectors. In mammals, ERKs participate in the regulation of spermatogenesis, mature spermatozoa motility, hyperactivation, and the acrosome reaction. To investigate ERK functions in Eriocheir sinensis reproduction, we successfully cloned the full-length ERK from the testis of E.

P38 participates in spermatogenesis and acrosome reaction prior to fertilization in Chinese mitten crab Eriocheir sinensis.

P38 mitogen-activated protein kinases (MAPKs) comprise a family of serine/threonine protein kinases that play important roles in cellular responses to inflammatory cytokines and environmental stresses. These kinases are involved in controlling cell division, differentiation and death in mammalian testes and therefore are critical to spermatogenesis. To explore their functions in male reproduction of Chinese mitten crabs, Eriocheir sinensis p38 (Es-p38) protein expression was determined in different tissues including testes at different developmental stages by Western blot.
