Isolation, characterization, and bioactivities of compounds from Fuscoporia torulosa mushroom.

Chromatographic purification of Fuscoporia torulosa extracts resulted in the isolation and characterization of a new steroid, 5α,8α-epidioxyergosta-6,22-dien-3β-il-palmitate (1) and 10 known compounds (2-11). The structures of compounds were elucidated by IR, NMR, MS analyses, and comparison with literature data. Cytotoxic activities against MCF-7 (breast cancer), PC-3 (prostate cancer), and 3T3 (nontumor) of the extracts and cytotoxic, antioxidant, cholinesterase, and tyrosinase inhibitory activities of all isolated compounds were evaluated.

Structural characterization and determination of biological activities for different polysaccharides extracted from tree mushroom species.

Chemical composition and structural characterization of polysaccharides of Fomes fomentarius (FF), Fuscoporia torulosa, Ganoderma adspersum, Ganoderma applanatum (GAP), Ganoderma lucidum, Phellinus igniarius, Pleurotus ostreatus (PO), and Porodaedalea pini (PP) tree mushrooms with antioxidant and anticholinesterase activities were determined in this research. Total carbohydrate contents of the polysaccharides were ranged between 65.06 ± 6.

Phenolic profiles, antioxidant, and anticholinesterase activities of three Gloeophyllum species with chemometric approach.

This study's aim was to determine the antioxidant and anticholinesterase activities of Gloeophyllum odoratum, Gloeophyllum sepiarium, and Gloeophyllum trabeum species with phenolic profiles. The major compound in G. odoratum (101.

Synthesis and characterization of electrospun PVA/Zn metal composite nanofibers for lipase immobilization with effective thermal, pH stabilities and reusability.

Polyvinyl alcohol (PVA)/Zn electrospun nanofibers that were a kind of polymer/ionic metal composite was successfully embedded in the hybrid fibers for the first time in the literature, due to chemical interactions between PVA and Zn. Also, the nanofibers were used as carriers for the first time in enzyme immobilization. The nanofibers were optimized and synthesized by electrospinning technique according to the operational parameters like as PVA concentration (%), Zn concentration (%), voltage (kV), needle tip-collector distance (cm) and injection speed (ml/h).

Chemical Profile, In Vitro Enzyme Inhibitory, and Antioxidant Properties of Stereum Species (Agaricomycetes) from Turkey.

Recently, mushroom species have been the focus of researchers' interest because of several bioactivities. The aim of this study was to investigate the chemical profile and biological activities of various extracts of two Stereum species (S. rugosum and S.

Natural calcium phosphates from fish bones and their potential biomedical applications.

The treatment and recovery of bio-wastes have raised considerable attention both from the environmental and economic point of view. Every year, a remarkable amount of fish processing by-products are generated and dumped as waste from all over the world. Fish bones can serve as a raw material for the production of high value-added compounds that can be used in various sectors including agrochemical, biomedical, food and pharmaceutical industries.

Serum indoleamine 2,3 dioxygenase and tryptophan and kynurenine ratio using the UPLC-MS/MS method, in patients undergoing peritoneal dialysis, hemodialysis, and kidney transplantation.

Background: The level and activity of indoleamine 2,3-dioxygenase (IDO) and the concentrations of L-tryptophan and its metabolite L-kynurenine were determined in association with various renal diseases. However, there have been no data regarding these parameters in patients on peritoneal dialysis compared to those undergoing hemodialysis or kidney transplantation.

Methods: This study investigated the level and activity of IDO and determined oxidative balance by calculating the total oxidant status (TOS), total antioxidant status (TAS), and oxidative stress index (OSI).
