in recent years, several plant species have been used as bioindicators, and several tests have been developed to evaluate the toxicity of the environmental contaminants. in this study, the root length and dna band pattern of root tips in maize (zea mays l.) seedlings were exposed at different concentration of cadmium pollutant (40 and 80 mg l−1). the results indicated that the root length of ma...

the genetic diversity of 89 flue-cured tobacco varieties was examined using 12 issr primers. these cultivarswere evaluated at the guilan tobacco research center, rasht, iran, using a 7×7 simple lattice design with two replications, and 12 morphological traits. the total number of pcr amplified products was 143 bands ranging from 450 to 3000 bp, of which 108 bands (74.28%) were polymorphic. prim...

Amniotic Band Syndrome is a sporadic congenital disorder that may result in constriction bands, amputation and multiple craniofacial, visceral and body wall defects. Its incidence is estimated at approximately 1:5000 to 1:10,000 pregnancies. Band formation most frequently affects the distal segments, including the hand. We report a case of constriction amniotic bands involving the trunk.

copper is most toxic metal in marine organisms. characterization of protein occurring in the metabolically active tissues of muscle (mu), hepatopancreas (hp) and gills (gl) of the spiny lobster, panulirus homarus homarus on exposure to two sub-lethal doses (9.55 and 19.1 µg/l) of copper were studied for 28 days of exposure (doe). the electrophoretic pattern of muscle, hepatopancreas and gill pr...
