Melatonin alleviated chilling injury of cold-stored passion fruit by modulating cell membrane structure via acting on antioxidant ability and membrane lipid metabolism.

Fresh passion fruit is sensitive to chilling injury (CI) during storage at improper low temperature of 5 °C, which lowers the fruit quality and limits its shelf life. The present study aimed to determine the impacts of melatonin on CI development of passion fruit in relation to antioxidant ability and membrane lipid metabolism during refrigeration. In present study, passion fruit was treated with 0.

Comparative Analysis of the Benefits of Glutathione-Rich Yeast Hydrolysate and Astaxanthin on Growth Performance, Antioxidant Capacity and Lipid Metabolism in Pacific White Shrimp (Litopenaeus vannamei).

Antioxidants, both glutathione (GSH) and astaxanthin (AX), possess beneficial applications in animal growth and antioxidant properties. In this study, three experimental diets with isoproteic and isolipidic were formulated, the control diet (CON), the control diet added with 0.03% Carophyll Pink (contains 10% AX), the control diet added with 0.

Dietary Tryptophan Requirement of Juvenile Hybrid Grouper (♀ ♂).

A 10-week feeding study was conducted to examine the effects of dietary tryptophan (Trp) levels on the growth performance and protein metabolism of hybrid grouper (♀ × ♂) with the aim of determining the optimal Trp requirement. Six isonitrogenous and isolipidic experimental diets were formulated, containing varying levels of Trp (0.26%, 0.

Direct Knitting of Pincer Palladium Complexes into Hyper-crosslinked Polymers for Superior Catalytic Performance in Suzuki-Miyaura Reactions.

Using a direct knitting strategy, we successfully prepared a novel heterogeneous catalyst consisting of pyridine-bridged bis(imidazolium-2-ylidene) palladium complexes (CNC-Pd) embedded in a knitted network polymer. The resulting catalysts (HCP-CNC-Pd-d) exhibited high specific surface areas of 982 m2 g-1 with microporous and mesoporous structures. The large surface area enhances contact between the substrate and the catalytic center, while the strong chelation between CNC and the metal ion ensures the catalyst's durability.

Palladium(II)-Catalyzed Enantioselective Ring Opening of Oxabenzonorbornadienes via Domino Aminopalladation of Alkynylanilines.

We report herein a robust enantioselective ring opening coupling of oxabenzonorbornadienes via Pd(II)-catalyzed domino cyclization of alkynylanilines, which features the formation of three covalent bonds and two contiguous stereocenters with excellent enantio- and diastereoselectivity and a broad substrate scope. The good functional group tolerance of this domino desymmetrization strategy enables efficient late-stage transformation of natural product-derived alkynylanilines. The resulting indolated dihydronaphthols could serve as a valuable platform to streamline the diversity-oriented synthesis of other valuable enantioenriched tetrahydronaphthalene derivatives.
