Bee pollen, known as a ‘life-giving dust’, is product of honeybees using flower pollen grains and combining them with their saliva secretions. Thus, could be an indicator the bee botanical source. Identification sources highly crucial process for evaluation its health benefits, chemical composition directly related to pharmacological activity. In this study, profiles, contents phenolic marker c...
Background: The use of medicinal plants is an option for livestock farmers who are not allowed to use allopathic drugs under certified organic programs or cannot afford to use allopathic drugs for minor health problems of livestock. Methods: In 2003 we conducted semi-structured interviews with 60 participants obtained using a purposive sample. Medicinal plants are used to treat a range of condi...
Applications of gibberellic acid to the mature form of Hedera helix induce morphological reversions to the juvenile form of growth. The juvenile forms produced are stable with time and differ dramatically from the mature in phenotype. DNA-RNA hybridization techniques have been used to study the RNA populations of juvenile, mature and gibberellic acid-treated mature apices. Hybridization competi...
Circular polarization spectroscopy has proven to be an indispensable tool in photosynthesis research and (bio)-molecular research in general. Oxygenic photosystems typically display an asymmetric Cotton effect around the chlorophyll absorbance maximum with a signal ≤ 1%. In vegetation, these signals are the direct result of the chirality of the supramolecular aggregates. The circular polarizati...
