Rhodiola crenulata inhibits the tumorigenic properties of invasive mammary epithelial cells with stem cell characteristics
Rhodiola is a high altitude perennial plant that is widespread in Eastern Europe and Asia. The root of the Rhodiola plant has been used for many years in eastern traditional medicine and it is well known for cardio-protective and central nervous system enhancement effects. It is considered a plant-derived “adaptogen” which is capable of maintaining a physiological homeostasis upon...

Antibacterial and anti-inflammatory effects of honeybee (Apis mellifera) venom against acne-inducing bacteria
Acne vulgaris is a chronic inflammatory disorder of the sebaceous follicles.Propionibacterium acnes plays a critical role in the development of these inflammatory lesions. The present study was conducted to evaluate the antimicrobial property of honeybee (Apis mellifera L.) venom (BV) against the etiologic agents of acne vulgaris. Incubation of the skin bacteria P. acnes, clindamycin-resistant P....

Molecular cloning and characterization of the secoisolariciresinol dehydrogenase gene Involved in podophyllotoxin biosynthetic pathway from Tibet Dysosma
Secoisolariciresinol dehydrogenase catalyzes the conversion of secoisolariciresinol into matairesinol that is a central precursor of antiviral and anti-tumor podophyllotoxin. The full - length cDNA encoding secoisolariciresinol dehydrogenase (designated as DtSD) was cloned and characterized from Tibet Dysosma, Dysosma tsayuensis Ying. The full-length DtSD cDNA was 994 bps containing an 837-bp open reading...

Possible nitric oxide modulation in protective effects of withaferin A against stress induced neurobehavioural changes
The involvement of nitric oxide (NO) in stress-induced neurobehavioral changes in rats was evaluated using the elevated plus maze and open field tests. Restraint stress (1 h) reduced both the number of entries and time spent in open arms, with both expressed vehicle- controls and these changes were reversed with diazepam (1 mg/kg) and withaferin A(10 - 50 mg/Kg, i.p), N-nitro-L -arginine methyl ester ( L-NAME) (50...

Larvicidal activities of ethanol extract of Allium sativum (garlic bulb) against the filarial vector, Culex quinquefasciatus
Vector control is facing a threat due to the emergence of resistance to synthetic insecticides. Insecticides of botanical origin may serve as suitable alternative biocontrol techniques in the future. Garlic bulbs are common and widely distributed in many parts of Nigeria with medicinal properties, but the larvicidal activity of this plant has not been reported so far. Ethanol extract of Allium...
