nigella sativa (ns) (ranunculaceae family) is generally utilized as a therapeutic plant all over the world. the seeds of the plant have a long history of use in different frameworks of medicines and food. in islamic literature, it is considered as one of the greatest forms of therapeutics. it has been widely used to treat nervous system diseases such as memory impairment, epilepsy, neurotoxicit...

Bioactive glass-ceramic is used as a replacement material for bone tissue due to its compatibility, bioactivity, and the ability form crystallized hydroxyapatite layer, which similar in composition structure inorganic component of mineral phase. In this paper, bioglass-ceramic was toughened using zirconia improve mechanical behaviour (i.e. crack opening dsplacement fracture toughness). The toug...

bioactive glasses are silicate-based and can form a strong chemical bond with the tissues. these biomaterials are highly biocompatible and can form a hydroxyapatite layer when implanted in the body or soaked in the simulated body fluid. due to several disadvantages, conventional glass processing method including melting of glass components, is replaced by sol-gel method with a large number of b...

HIGHLIGHTS • Extruded corn snacks (ECS) were developed with red dog flour (RDF), rich in ash, protein, dietary fiberand bioactive component. The best-optimized snack wasdetermined a 20% RDF ratio. addition of the increased nutritional and functional properties ECS. Extrusion greatly reduced phytic acid content ECS containing RDF.

objective(s):the current study was aimed to determine the bioactive constituents and biological effects of the crataegus monogyna ethanolic extracts from bark, leaves and berries on hypercholesterolemia. materials and methods: oleanolic acid, ursolic acid, quercetin and lupeol concentrations were quantified by hplc. total phenol content and radical scavenging activity of extracts were also meas...

traumatic brain injury (tbi) is a common reason of brain tissue loss as a result of tumors, accidents, and surgeries. renewal of the brain parenchyma is restricted by many reasons such as inimical substances produced as the result of trauma and also inflammatory responses. a strong cascade of inflammatory responses begins as a result of tbi which include recalling peripheral leukocytes into the...

traumatic brain injury (tbi) is physical damage to the brain structure which has a high global rate of mortality and morbidity. tbi can cause intense inflammatory response due to accumulation of leukocytes in cerebral matrix and activation of microglia. microglia can differentiate into m1 macrophages or m2 macrophages following the changes in biochemical properties of brain tissue. m1 sub type ...

bioactive materials including glass and glass-ceramics are nowadays used as medical implants for orthopedic applications. in this study several samples of glass-ceramics have been prepared using both heat treatment and sol-gel processes. the structure and bioactivity of these samples based on their interaction with simulated body fluid (sbf) have been determined. in-vitor, using the raman spect...

In this work, the template, monomer, and cross-linker with the ratio of 1:8:40 were used to synthesize Molecularly Imprinted Polymers (MIPs) for extraction of the bioactive chemical compounds from some traditional herbs as a sorbent material. Quercetin, Methacrylic Acid (MAA), Trimethylolpropanetrimethacrylate (TRIM) and Tetrahydrofuran (THF) were used as a template, funct...
