Callus cultures from root explants of Lathyrus sativus L. ‘Derek’ were tested for their morphogenic capacity. Primary explants (fragments of roots) were cultivated on three induction media. We obtained three lines of callus tissue among which we identified two non-embryogenic lines and one embryogenic line. Callus originally cultivated on modified MS medium supplemented with 0.05 mgL picloram, ...
An efficient and reproducible procedure was established for direct shoot regeneration of Solanum surattense Bum. using internodal explants. The shoot regeneration efficiency on Murashige and Skoog (MS) medium supplemented with 6benzylaminopurine (BAP) was superior in compared to 6furfurylaminopurine (Kn). The highest mean number of shoots per explant was recorded on MS medium containing 0.5 mgl...
Alzheimer's disease (AD) is a progressive neurodegenerative disorder that identified by the gradual decline in memory and cognitive function. It classified deposition of Aβ plaques, build-up intracellular neurofibrillary tangle neuron loss. Neurotrophic factors play critical role treatment disease. However, utilization such neurotrophins has encountered certain difficulties side effects. Novel ...
Radiometric and Heavy Metal Analysis of Leachates in Selected Open Dumpsites in Port Harcourt Region
Leachates from selected open dumpsites in Port Harcourt region were analysed for radiometrics and heavy metal parameters. For radiometrics, gamma ray spectroscope was used while Heavy parameters spectrophotometer. These compared among the of different study areas established international standard FEPA WHO/INIS used. Dumpsites leachates show mean potassium 40K(71.715± 0.3 Bq kgl-), Uranium 238U...
Several biotic and abiotic stresses adversely affect sugarcane crop. Amongst the stresses, salinity causes substantial losses to yield. Lack of conducive environment for flowering unstable genome are main constraints in crop improvement via conventional breeding. Therefore, genetic engineering using Oryza sativa L. H+-PPase gene (OVP1) confer salt tolerance is preferred alternative strategy. In...
Methanolic and aqueous leaf extracts of Chrysophyllum albidum (African star apple) Garcinia kola (bitter kola) were studied for in-vitro microbial activity using the disc diffusion technique. The methanolic showed antimicrobial against Escherichia coli, Staphylococcus aureus Candida albicans but no antibacterial Klebsiella pneumonia. extract inhibited growth pneumonia while coli. Both plant ant...
Satureja bachtiarica L, an important medicinal plant from Lamiaceae family is valuable because of its medical compounds. Optimization of in vitro culture through callogenesis is proposed to be an alternative for vegetative propagation. In present study, an efficient protocol has been developed for callus induction of S. bachtiarica using different explants and concentrations of plant growth reg...
the objective of this study was to investigate the propensity of permethrin (ptn) to induce oxidative stress and changes in enzyme activities in liver of rainbow trout and its possible attenuation by vitamin c. forty-eight fish were randomly assigned to 1 of 6 treatment groups and their livers were used for liver perfusion method: control (0 μgl-1 permethrin and 0 mgl-1 vitamin c), ptn-0.16 (0....
در این تحقیق سیتوکینین¬های مختلف بر سرعت ریزازدیادی اسطوخودوس بررسی شد. جداکشت های دو گره¬ای سترون شده از یک گیاه گلخانه¬ای یکساله در محیط کشت MS دارای هورمون¬های بنزیل آمینو پورین(BAP)،2-¬ ایزوپنتنیل آدنین (2ip) و کینتین (Kin) به تنهائی یا در ترکیب با یکدیگر کشت شد. نتایج حاصل نشان داد سرعت رشد ریز قلمه ها، تعداد گره¬ها و نو ساقه¬های حاصل از هر جدا کشت در محیط کشت به نوع و غلظت هورمون بستگی دا...
