The effect of fungal elicitors and calcium-channel modulators on the anthocyanin production in callus cultures of Daucus carota was studied. It was found that the addition of fungal elicitors resulted in higher anthocyanin accumulation on the 3rd day of culture, but they resulted in lower levels of anthocyanin on the 21st day. Fungal elicitor treatment also affected growth of the cultures, as e...
in the present work, a simple and sensitive method was developed for determination of morphine and heroin using gold nanoparticles as resonance rayleigh scattering (rrs) and colorimetric technique’s probe. synthesized gold nanoparticles by sodium citrate reduction method have a negative charge layer on their surfaces because of self-assembled citrate anions on their surface. binding of morphin...
Withania somnifera, commonly known as Ashwagandha an important medicinal plant largely used in Ayurvedic and indigenous medicine for over 3,000 years. Being a medicinal plant, dried powder, crude extract as well as purified metabolies of the plant has shown promising therapeutic properties. Withanolides are the principal metabolites, responsible for the medicinal properties of the plant. Availa...
conclusions our underlying hypothesis is that recapitulating the three-dimensional early embryonic structure, in order to reproduce better in vitro the three-dimensional morphogenetic-like re-arrangements, would improve cells differentiation, when in vivo transplanted; moreover, it could be used as a simplified cancer disease model and reliable drug evaluation method as well. results the proces...
adaptation of the lord of the rings is considered by many to be among the greatest, most successful and at the same time most popular of the above mentioned trend so far. it is my intention to look at the success and popularity of this epic fantasy in the light of the 9/11 attacks and the war on terror context of g. w. bush’s aura. in so doing i aim at bringing into the light the determining fa...
postcolonial feminism, also dubbed as third world feminism, is an innovative approach, demonstrating the way women of colonized countries suffer from both native patriarchies and imperial ideology. also due to this double-colonization, postcolonial feminists contend that third world women are subjected to both colonial domination of empire and male domination of patriarchy. while western femini...
Background: Listeria monocytogenes may be the cause of meningitis and sepsis. It is transmitted via food products. Precise detection of this organism would undoubtedly play a significant role in prevention of this infection. Materials and methods: Polymerase chain reaction method was developed for detection of Listeria monocytogenes in milk samples after enrichment culture. It consists of cult...
The experiments were purposed to investigate the effect of chitosan and yeast extract on Stemona alkaloid production in Stemona sp. culture. Both elicitors enhanced Stemona alkaloid production over the control. Treatment with chitosan at a concentration of 25 mg/L for 1 week resulted in the highest production of Stemona alkaloids. It was found that 1', 2'-didehydrostemofoline and stemofoline pr...
Over the years it has been an important goal to optimize the treatment of subfertility in order to obtain a better pregnancy rate and baby-take-home rate, usually combined with the goal of decreasing the rate of multiplet pregnancies. This implies optimizing the development of embryos through improved in vitro culture methods. And it also implies optimizing the methods of selection of embryos f...
objective: mycoplasma salivarium (m. salivarium) isone of the most common contaminants present in cell culture laboratories that cause undesirable effects on cell cultures. thus, the identification and rapid diagnosis in controlling and prevention of this contaminant are important. the aim of this study is the detection of mycoplasma salivarium contamination in cell culture using polymerase cha...
