MoSe-Layered Nanosheet Decorated SnO Hollow Nanofiber-Based Highly Sensitive and Selective Room Temperature HS Gas Sensor.

In this work, we successfully demonstrated a MoSe@SnO nanocomposite-based room temperature HS gas sensor. A sensing mechanism was proposed based on experimental results and density functional theory calculations. The FESEM micrographs of the heterostructure formed by hydrothermally grown MoSe-layered nanosheets and SnO-hollow nanofiber result in a high surface area for HS gas adsorption.

Fabrication of MnFeO nanoparticles embedded chitosan-diphenylureaformaldehyde resin for the removal of tetracycline from aqueous solution.

In this study, a magnetic composite was synthesized using chitosan, diphenylurea and formaldehyde with magnetic nanoparticles, (MnFeO) via condensation polymerization. The newly synthesized magnetic nanocomposite (CDF@MF) was characterized using several analytical techniques including Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD) and etc. To investigate the applicability of CDF@MF, it was employed as an adsorbent for rapidly removal of an antibiotic, namely, tetracycline (TC), from aqueous solution using several factors such as pH, the adsorbent dose, the initial concentration and the contact time.

N/S doped highly porous magnetic carbon aerogel derived from sugarcane bagasse cellulose for the removal of bisphenol‑A.

In this study, highly porous N/S doped magnetic carbon aerogel (N/S-MCA) was successfully fabricated using sugarcane bagasse based cellulose and used for the removal of bisphenol‑A (BPA) from aqueous solution. The fabricated N/S-MCA nanocomposite derived from cellulose was characterized by various analytical techniques and supports the formation of the N/S-MCA in good yield and high purity. The batch adsorption studies were used for the adsorption of BPA onto N/S-MCA.

Ultra-fast spill oil recovery using a mesoporous lignin based nanocomposite prepared from date palm pits (Phoenix dactylifera L.).

Oil spills present the enormous harm to the environment, and its potential remediation for environmental protection is import worldwide. Herein, we report an effective strategy inspired by the lignin based bio-waste date palm pits powder (Phoenix dactylifera L.), which was modified with magnetic FeO nanocrystals and used as a porous, hierarchical graphite carbon oil/solvent sorption magnetic materials.

Fabrication of highly porous N/S doped carbon embedded with ZnS as highly efficient photocatalyst for degradation of bisphenol.

In the present study, a novel nanocomposite has been successfully fabricated that contain nitrogen and sulphur doped porous carbon and ZnS nanoparticles. The fabricated nanocomposite has been used as a photocatalyst for the photocatalytic degradation of bisphenol-A (BPA) under visible light. The prepared nanocomposite was characterized using FT-IR, XRD, Raman, SEM, TEM, SAED, BET and XPS.

Fabrication of hybrid nanocomposite derived from chitosan as efficient electrode materials for supercapacitor.

A novel high-performance supercapacitor was fabricated using spinal (nickel ferrite) nanoparticles uniformly implanted into nitrogen-doped carbon matrix. The nanocomposite was fabricated with bimetallic polymer complexes for the first time. The fabricated nanocomposite was characterized using FTIR, TGA, Raman, XRD, BET, XPS, SEM and TEM technique.

Differentiation of steroid-producing cells and folliculogenesis in the developing ovary of the Nile tilapia Oreochromis niloticus.

Differentiation and development of steroid-producing cells (SPCs) and folliculogenesis during ovarian differentiation in the Nile tilapia Oreochromis niloticus were immunohistochemically and ultrastructurally examined. Clusters of immunopositive cells (IPCs) against antibodies (ABs) of cholesterol side-chain cleavage cytochrome P450 (P450scc), 3β-hydroxysteroid dehydrogenase (3βHSD), and cytochrome P450aromatase (P450arom) only appeared in the area near blood vessels in the fish ovaries at 50-60 days after hatching (dah). Ultrastructural results showed that differentiation and development of SPCs from undifferentiated to maturation occurred in the area near blood vessels, indicating that it would be the original site of SPCs.

Efficacy of exemestane, a new generation of aromatase inhibitor, on sex differentiation in a gonochoristic fish.

We report the first use of exemestane (EM), a steroidal aromatase inhibitor (AI) commercially known as aromasin, in studies of sex differentiation in fish. The effectiveness of EM was examined in two different age groups of the gonochoristic fish, Nile tilapia (Oreochromis niloticus). Untreated control fish (all female) showed normal ovarian differentiation through 120 days after hatching (dah), whereas fish treated with EM at 1000 and 2000 microg/g of feed from 9 dah through 35 dah, the critical period for sex differentiation, exhibited complete testicular differentiation; all stages of spermatogenic germ cells were evident and well developed efferent ducts were present.

Tissue-specific interactions of TNI isoforms with other TN subunits and tropomyosins in C. elegans: the role of the C- and N-terminal extensions.

The aim of this study is to investigate the function of the C-terminal extension of three troponin I isoforms, that are unique to the body wall muscles of Caenorhabditis elegans and to understand the molecular interactions within the TN complex between troponin I with troponin C/T, and tropomyosin. We constructed several expression vectors to generate recombinant proteins of three body wall and one pharyngeal troponin I isoforms in Escherichia coli. Protein overlay assays and Western blot analyses were performed using antibodies.

Tissue expression of four troponin I genes and their molecular interactions with two troponin C isoforms in Caenorhabditis elegans.

Gene duplication is a major genetic event that can produce multiple protein isoforms. Comparative sequence and functional analysis of related gene products can provide insights into protein family evolution. To characterize the Caenorhabditis elegans troponin I family, we analyzed gene structures, tissue expression patterns and RNAi phenotypes of four troponin I isoforms.
