Halophilic bacteria grow over a wide range of salt concentrations. In this study we aimed to isolate and screen out the halophilic bacteria and to determine their activity for production of the bioactive compounds. A total of 50 water, sediments and soil samples were collected from Maharlu salt lake in southern region of Fars-Iran and subjected for isolation of the bioactive compound producing ...

The seeds of Psoralea corylifolia L. (P. corylifolia), also known as "Bo-Gol-Zhee" in Korea, are used in a traditional herbal medicine for treating various skin diseases. In the present study, we performed quantitative analyses of the seven standard components of P. corylifolia: psoralen, angelicin, neobavaisoflavone, psoralidin, isobavachalcone, bavachinin, and bakuchiol, using high-performanc...

Bone regeneration is a process of vital importance since fractures of long bones and large joints have a highly deleterious impact on both, individuals and society. Numerous attempts have been undertaken to alleviate this severe medical and social problem by development of novel bioactive materials, among which bioactive glass is the most attractive because of its osteoconductive and osteostimu...

Rauwolfia species (Apocynaceae) are medicinal plants well known worldwide due to its potent bioactive monoterpene indole alkaloids (MIAs) such as reserpine, ajmalicine, ajmaline, serpentine and yohimbine. Reserpine, ajmalicine and ajmaline are powerful antihypertensive, tranquilizing agents used in hypertension. Yohimbine is an aphrodisiac used in dietary supplements. As there is no report on t...

The plant Cecropia pachystachya Trécul is widely used in Brazilian ethnomedicine to treat hypertension, asthma, and diabetes. Arginase is an enzyme with levels that are elevated in these disorders, and it is central to Leishmania polyamine biosynthesis. The aims of this study were to evaluate antileishmanial activity and inhibition of the arginase enzyme by C. pachystachya extracts, and to stud...

Nutrition influences sleep. Drinking a glass of warm milk in the evening has been a long term tradition in several cultures. Although most of these reports are anecdotal, several milk components have been associated with sleep, such as tryptophan, bioactive peptides and magnesium. The widest researched dairy component in relation to sleep is tryptophan. Tryptophan is the precursor of serotonin....

Ligustilide is the most abundant bioactive ingredient in Rhizoma Chuanxiong, a Chinese medicinal herb commonly used for the treatment of cardiovascular ailments. The present study reported, for the first time, the pharmacokinetics of ligustilide, administered in its pure form and in an herbal extract, in rats. After i.v. administration of pure ligustilide, it was distributed extensively (V(d), ...

CuO, Fe2O3, MnO2 and ZnO substituted 45S5 bioactive glasses were prepared. Glass derived Bioactive Glass ceramics were obtained through controlled crystallization of bioactive glasses. The formed crystalline phases in bioactive glass ceramics were identified using X ray diffraction (XRD) analysis. Density and ultrasonic wave velocities of bioactive glasses and glass ceramics were measured and u...

Haemanthus coccineus extracts (HCE) have traditionally been used to treat a variety of diseases, like febrile colds or asthma. Since new therapeutic options against inflammatory processes are still urgently needed, we aimed to pharmacologically characterise the anti-inflammatory potential of HCEin vitro and in vivo and to identify the underlying bioactive component(s). The action of HCE on oede...

background: the greater surface of bioactive glass nanoparticles presents an incomparable and promising feature similar to the biological apatite. nanoparticles improve cellular adhesion, enhance osteoblast proliferation and differentiation, and increase biomineralization for periodontal regeneration and dental implants. considering the fact that interaction between periodontal cells and bone g...
