Evaluation of biocomposite putty with strontium and zinc co-doped 45S5 bioactive glass and sodium hyaluronate.

The application of powder or granule formed bioactive glasses in the defect area with the help of a liquid carrier to fill the defects is a subject of interest and is still open to development. In this study, it was aimed to prepare biocomposites of bioactive glasses incorporating different co-dopants with a carrier biopolymer and to create a fluidic material (Sr and Zn co-doped 45S5 bioactive glassessodium hyaluronate). All biocomposite samples were pseudoplastic fluid type, which may be suitable for defect filling and had excellent bioactivity behaviors confirmed by FTIR, SEM-EDS and XRD.

GC/MS Analysis of Alkaloids in Baker and Determination of Its Anticholinesterase Activity.

Objectives: Amaryllidaceae alkaloids are well known for their wide range of pharmacological activities. Galanthamine, an Amaryllidaceae alkaloid, is an effective, selective, reversible, and competitive cholinesterase inhibitor marketed under different commercial names in several countries for the treatment of Alzheimer's disease. The aim of this work was to study the alkaloid profiles of the aerial parts and bulbs of both flowering and fruiting periods of Baker (Amaryllidaceae), as well as analyzing their inhibitory activities on both acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) for the first time.

Characterization of phenolic profile by LC-ESI-MS/MS and enzyme inhibitory activities of two wild edible garlic: Allium nigrum L. and Allium subhirsutum L.

In our study, Allium nigrum L. and Allium subhirsutum L. were investigated in terms of phenolic profile, acetylcholinesterase (AChE), butyrylcholinesterase (BuChE), and tyrosinase inhibitory potentials.
