Genetic Variation and the Electrocardiograph

phylogeography and genetic diversity of the lesser mouse- eared bat (myotis blythii) in iran

in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...

The beginnings and development of the electrocardiograph.

In 1791, Galvani, in Italy, first showed electromotor activity in the leg muscle of the frog (1). Action potentials of skeletal muscle were later found by several physiologists in the 19th century and in the 1870s, electromotor phenomena were found in heart muscle using exposed animal hearts. Lippman in Paris, in 1872, invented the capillary electrometer which could demonstrate cardiac electric...

Genetic Variation in MMP-1 Promoter Region and

Magnetic tape recording electrocardiograph.

R ECORDING the electrocardiogram for prolonged intervals presents difficulties from the standpoint of economy and convenience. One 200 foot roll of paper for a direct writing instrument is used in 40 minutes of continuous recording at 25 mm. per second, and reviewing this long electrocardiographic record is a cumbersome procedure. A convenient method of recording electrocardiograms and fied ele...

assessment of the genetic variation and drought tolerance among genotypes

this experiment was conducted to evaluate the drought tolerance of cultivated (carthamus tinctorius l.) and wild safflower (c. oxyacanthus bieb) populations at research farm of college of agriculture, isfahan university of technology located at lavark-najafabad in 2008. a randomized complete block design with 3 replications was used in each of irrigation levels after 80, 130 and 180 mm evaporat...
