Redescription of A. Adam, 1861 (Truncatelloidea, Stenothyridae), with the first complete mitochondrial genome in the family Stenothyridae.

In this study, belonging to the truncatelloid family Stenothyridae is redescribed using morphological characters from the shell, operculum, and radula. The species is distinguished from other species in the group by its shell without spotted spiral lines and by its dome-shaped, mostly smooth, protoconch with some pits. Together with the morphological description, the complete mitogenome for the species is provided, which fill a knowledge gap in Stenothyridae.

Three-dimensionally ordered macro-mesoporous CoMo bulk catalysts with superior performance in hydrodesulfurization of thiophene.

The introduction of surfactants during the fabrication of hydrodesulfurization catalysts could not only tune the microstructure but also promote the dispersion of active components. In this work, CoMo bulk catalysts with the hierarchical structure of three-dimensionally ordered macro-mesopores were successfully fabricated by using a colloidal crystal template with the addition of PEG 400 and/or F127 surfactants. The obtained samples were characterized by various techniques, and the possible mechanism of the structure formation was also discussed.

The Thunnini, or tuna, comprise many species with very different commercial values. The principal raw tuna product on the market is sashimi, for which the species used is difficult to identify through conventional morphological analysis. The present study amplified the cytochrome gene () of 4 major tuna species used for preparing sashimi-yellowfin tuna (), southern bluefin tuna (), bigeye tuna (), and Atlantic bluefin tuna ()-and 4 species commonly mislabeled as components of tuna sashimi-albacore tuna (), skipjack tuna (), striped marlin (), and swordfish ().

Polymeric nanoparticles based on carboxymethyl chitosan in combination with painless microneedle therapy systems for enhancing transdermal insulin delivery.

Biodegradable nanoparticles (NPs) have been frequently used as insulin transdermal delivery vehicles due to their grand bioavailability, better encapsulation, controlled release and less toxic properties. However, the skin's barrier properties prevent insulin-loaded NP permeation at useful levels. Nowadays, microneedles have been spotlighted as novel transdermal delivery systems due to their advantages such as painlessness, efficient penetration and no hazardous residues.

Effect of different cooking methods on sensory quality assessment and in vitro digestibility of sturgeon steak.

Sous vide can keep the nutritional properties and improve taste of food compared with other conventional methods. In addition, this method may reduce the risk of recontamination after cooking and during storage. The purpose of this paper was to study the effects of four cooking methods (steaming, microwaving, baking, and frying) on the sensory and digestibility on sturgeon steak pretreated by sous vide during the cold storage (0-25 days).

Polysaccharides derived from for the removal of silver nanoparticle-humic acid contaminants by a coagulation-ultrafiltration process.

Silver nanoparticles (AgNPs) pose serious health risks to humans as the adsorption between AgNPs and humic acid (HA) makes it difficult to remove them from surface water. To solve this problem, polysaccharides extracted from a marine alga, (denoted as Ep), were used to eliminate the AgNP-HA composite contaminant a coagulation-ultrafiltration (C-UF) process. The structure of Ep, AgNP-HA removal mechanism and membrane fouling were analyzed.

TRPV1 is a ligand-gated ion channel and plays an important role in detecting noxious heat and pain with an unknown mechanism. RhTx from Chinese red-headed centipede activates the TRPV1 channel through the heat activation pathway by binding to the outer pore region, and causes extreme pain. Here, we synthesized RhTx and its retro-isomer RL-RhTx.

Corrosion inhibition of mild steel by the hydrolysate of an imidazoline-based inhibitor in CO-saturated solution.

The synthesized imidazoline phosphate quaternary ammonium salt has low stability, which is spontaneously and rapidly hydrolyzed to the long-chain fatty acid amide (LFA). The hydrolysate (LFA) has been found to be an efficient inhibitor for Q235 steel against CO corrosion, which yields a maximum value above 90% at a concentration of 1000 mg L. The LFA inhibitor acts as an anodic type inhibitor and its inhibition mechanism is a "negative catalysis effect".

Fabrication of a low-cost adsorbent supported zero-valent iron by using red mud for removing Pb(ii) and Cr(vi) from aqueous solutions.

In this study, a granular red mud supported zero-valent iron (ZVI@GRM) was successfully prepared and was used to remove Pb(ii) and Cr(vi) from aqueous solution. Zero-valent iron (ZVI) was synthesized by direct reduction of iron oxide in red mud by maize straw as a reductant at 900 °C in an anoxic atmosphere. The technical characterization (SEM, EDS, XRD, FTIR and BET) revealed that ZVI@GRM was loaded with zero-valent iron and contained different size pores.

Dual-doped hierarchical porous carbon derived from biomass for advanced supercapacitors and lithium ion batteries.

Appraisal of Cu(ii) adsorption by graphene oxide and its modelling artificial neural network.

Graphene oxide (GO), as an emerging material, exhibits extraordinary performance in terms of water treatment. Adsorption is a process that is influenced by multiple factors and is difficult to simulate by traditional statistical models. Artificial neural networks (ANNs) can establish highly accurate nonlinear functional relationships between multiple variables; hence, we constructed a three-layered ANN model to predict the removal performance of Cu(ii) metal ions by the prepared GO.

Effects of three products from Antarctic krill on the nitrogen balance, growth, and antioxidation status of rats.

A few studies conducted over the past few decades have demonstrated the health benefits of a diet rich in marine products, but limited studies have investigated the effects of different krill products on the nitrogen balance and their potential health benefits. In our study, after a 14-day acclimation period, 50 female Sprague-Dawley rats were randomly assigned to five groups, each of which was fed a different diet, for 28 days. We then evaluated the effect of krill protein complex (KPC), krill powder, and defatted krill powder on the nitrogen balance, growth, and antioxidant activity through analyses of MDA, CAT, GSH-Px, and T-SOD.

Fe/Ni particles were prepared by reducing ferric chloride with sodium borohydride and supported on the produced porous material. Various techniques including X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy analysis (SEM) were employed to characterize the crystal phase, surface area, surface morphology and functional groups.

The genetic structure will illuminate potential mechanisms for population dynamics and sustainability, which are critical for preservation of biodiversity and for decision-making in management and restoration.

[Research progress on Chinese herbal medicine fermentation and profile of active substances derived].

Chinese herbal medicines( CHMs) are a class of preparations made from natural plants that pose health beneficial properties as well as illness prevention functions. Thanks to a panel of salutary features,such as comprehensive immunological enhancement and inhibition of pathogenic bacteria,negligible side-effects,inappreciable drug-resistance,CHMs have been taken as one of the costeffective candidates for antibiotics substitutions. Through probiotics fermentation,the enzymatic hydrolysis of matrixes of CHMs enables easier release of the active ingredient as well as endows less toxicity of the preparations derived.
