Genetic Engineering and Biotechnology of Growth Hormones

In its modern conception, biotechnology is the use of genetic engineering techniques to manipulate microorganisms, plants, and animals in order to produce commercial products and processes that benefit man. These techniques, which are the backbone of the biotechnological revolution that began in the mid 1970s, have permitted the isolation and manipulation of specific genes and the development o...

genetic variation and genetic gain from selection in bread wheat

genetic variation is necessary factor for continued breeding and increasing genetic gain from selection in crop plants. to evaluate genetic variation and genetic gain from selection in bread wheat, 45 genotypes consisting of 9 cultivars and their 36 crosses were grown in a randomized complete block design with three replications in research farm of isfahan university of technology. the phenotyp...

Genetic Variation and Atherosclerosis

A family history of atherosclerosis is independently associated with an increased incidence of cardiovascular events. The genetic factors underlying the importance of inheritance in atherosclerosis are starting to be understood. Genetic variation, such as mutations or common polymorphisms has been shown to be involved in modulation of a range of risk factors, such as plasma lipoprotein levels, ...

Seasonal variation in calcitropic hormones and bone accrual in puberty.

The production of 25-hydroxycholecalciferol (25(OH)D) in the liver is dependent on vitamin D obtained from the diet and from exposure to UV light. UV rays stimulate the conversion of provitamin D in the skin to vitamin D, making it available to the liver for hydroxylation to 25(OH)D. The circulating concentrations of 25(OH)D are considered to be reflective of the individual’s total vitamin D ex...
