Neuropeptides play a pivotal role in the control of metabolic homeostasis. We aimed to evaluate the release of neuropeptides involved in the control of energy homeostasis in relation to metabolic status in aging humans. The study group consisted of 183 women: 75 centenarians (above 100 yrs old), 26 elderly women (below 70 yrs), 45 younger women (mean 26 yrs) and 37 obese women (mean 41.6 yrs). Fasting...
In recent years an increasing interest in biological plant protection methods is being observed. The reason for developing biological control methods is the occurrence of resistance of pests to chemical pesticides, which induces the ecological danger for natural environment. In view of current achievements and development perspectives for biopesticides usage in plant protection the results regarding...
The tissue culture of Ch. cinerariaefolium was maintained on the different media. Addition of carbendazim (500 mg/dm3) and ascorbinic acid (1000 mg/dm3) strongly stimulated Pyrethrins biosynthesis. Differentiation of calluss culture on medium with gibberelic acid GA3 remarkably increased yield of Pyrethrins. The cell suspension culture was initiated from callus. Addition of Pyrethrins biosynthesis...
Tissue culture of leaf explants of Chrysanihemum cinerariaefolium Vis. was established on 6 solid media (RT and MS with various conbinations of hormones) to determine the most favourable medium content. Obtained callus culture were transferred onto regenerating media.Differentiation of tissue was the best on MS + kinetin 2 mg/dm3 + NAA 0,02 mg/dm3 + GA 10 mg/dm3. Regeneration of Ch.cinerariaefolium...
Callus tissue culture of Solanum laciniatum Ait. which is a source of diosgenin used in pharmaceutic industry was initiated from leaves and shoots explants on KD solid medium with various combinations of phytohormones. Culture was maintained at 25°C, light intensity 1700 lux and photoperiod 16 h. Obtained callus was treated with plant growth regulators to induce tissue differentiation. Regenerated...
Tissue cultures of Tagetes erecta Linn. were initiated from leaves and flowers on MS and RT media with various cytokinins and auxins combinations Cultures were maintaned at 25°C, light intensity 3000 lux and photo-period 16 h. Obtained callus tissue was transferred on regeneration medium (MS plus various combinations of growth regulators) for differentiation. The best organogenesis was observed on...
