ABSTRACT Melicope lunu-ankenda is commonly used in traditional medicine. The conventional propagation method for this species is inefficient due to low propagation rate and its lengthy period to maturity. In addition, insufficient planting materials often pose a problem for the plantation sector. The tissue culture technique is best alternative to overcome the problems. The callus induction and direct shoot regeneration...

ABSTRACT Acaricide resistance is a major problem that hinders the control of the cattle tick Rhipicephalu s (Boophilus) microplus in Mexico. Permethrin (P), cypermethrin (C) and zeta-cypermethrin (Z) have been used to control R. (B.) microplus , and tick populations have developed resistance to these acaricides. The aim of the present study was to evaluate the effectiveness of a mixture containing P, C, or Z mixed with plant extracts through in vitro laboratory bioassays, using susceptible and triple resistant (San Alfonso) R. microplus strains. Untreated controls received only water. Resul...

ABSTRACT All the evidences point out to the fact that the incidence, mortality and number of persons living with cancer are on the rise and, thus, this will impose a significant burden on health care resources. The considerable number of deaths from cancer necessitates the need to developing novel alternative cures that are efficient, safe, cheap and easy to use. In the search for new therapies for tumors, naturally-derived compounds have been considered as a good source of novel anticancer drugs. The challenge here is to find products that are pharmacologically active against tumor cells with suitable toxicity profile and least damage to normal cells. Curcumin is a spice widely used in many countries...

ABSTRACT Plant cell, tissue and organ culture is a set of techniques designed for the growth and multiplication of cells and tissues using organic nutrients in an aseptic and controlled physical environment. The exact conditions required to initiate and sustain plant cells in culture, or to regenerate intact plants from cultured cells, are different for each plant species. Tissue culture practices have shown that three factors namely explant choice, medium composition and control of the physical environment, are important in successful cultures. When completely defined plant culture media did not give the desired results, employing natural orga...
