microalgal growth curve, after the exponential phase, shows a stationary phase where algalbiomass production is inhibited and remains constant by some factors such as nutrientdepletion and intrinsic behavior. the present study is concerned with evaluating effects ofthe culture medium condition and intrinsic behavior on biomass production by dunaliellatertiolecta. to this end, effect of ph, nutr...

introduction based on previous researches, dental pulp stem cells (dpscs) are easily accessible with limited morbidity after collection. their embryonic origin, from neural crests, explains their multipotency. dpscs are primarily derived from the pulp tissues of the teeth.objective: this study was undertaken to isolate, culture, and characterize two different third molar and first premolar huma...

Background: Plumbagin is as an important bioactive secondary metabolite found in the roots of Plumbago spp. The only one species, Plumbago europaea L., grows wild in Iran. The therapeutic use of plumbagin is limited due to its insufficient supply from the natural sources as the plants grow slowly and take several years to produce quality roots. O...

objective(s) studies have shown that morphine, in addition to its analgesic properties, has several effects on cell proliferation and apoptosis. there is also evidence that opioid receptors are present on chondrocytes. our main objective in the present study was to investigate the effects of morphine on rat femur growth cartilage. materials and methods this research was carried out on 18 4-week...

Ovarian cancer is one of the major causes of death in women. Parabens are a class of chemicals widely used as preservatives in cosmetic and pharmaceutical products, they mimic estrogens, which are known to play a role in the development of different cancers in women. The Aim of this study was to investigate the proliferative effects of Methyl Paraben (MP) and Propyl Paraben (PP) on human ovaria...

A fundamental observation in the social and behavioral sciences is that people change over time, but not necessarily in the same way or at the same rate. For example, verbal ability increases steadily throughout the elementary school years, but it does not increase at the same rate for all students. There are individual differences in the rate and direction of change in many contexts, and these...
