mastitis is one of the most serious and costly diseases affecting dairy cattle production. in the present study, effects of a lactoferrin gene polymorphism (intron 6) on milk somatic cell count (scc) and subclinical mastitis was investigated in 121 holstein dairy cattle. two alleles of a and b and two genotypes of aa and ab were found in an ecori recognized single nucleotide polymorphism in int...
abstract somatic embryogenesis is a new approach to in vitro plant propagation. this technique is based on stem cell obtain and its differentiation to a complete plant. this is affected by components of media culture. so, the effects of ms, b5 and nl media on carrot petiole somatic embryogenesis investigated via histological experiment. to do this, carrot petioles (with 1 cm dimension) cultured...
Synthetic seeds can use as tool for applied biotechnology methods for improve the quality and increase the production of sunflower. Shoot tips excised from in vitro proliferated shoots were encapsulated in calcium alginate beads. The best gel complexation was achieved using 3% sodium alginate and 100 mM CaCl2.2H2O. Maximum percentage response for conversion of encapsulated shoot tips into plant...
Abstract: Background: Acromegaly is due to excess of growth hormone production and imbalance of cell growth which leads to somatic manifestations and organ dysfunction. With increasing life span an increasing incidence of colorectal, breast, and blood cancers is seen. In this paper we report a 57 year old male with acromegaly he had developed a swelling in the right breast for the last 2 yea...
Genetic improvement of garlic through conventional breeding is very difficult due to sterile nature of its flower. Hence, an alternative system is desirable to induce genetic variation. Tissue culture could be a good opportunities and somatic embryogenesis is one of the potential techniques of tissue culture for in vitro regeneration of garlic plant. The successes and production of somatic embr...
The mechanisms that control the growth rate of internal tissues during postembryonic development are poorly understood. In insects, the growth rate of imaginal disks varies with nutrition and keeps pace with variation in somatic growth. We describe here a mechanism by which the growth of wing imaginal disks is controlled. When wing imaginal disks of the butterfly Precis coenia are removed from ...
PIK3CA-Related Overgrowth Spectrum (PROS) refers to rare syndromes, which are characterized by malformations and excessive tissue growth caused somatic mutations in the PIK3CA gene occurring during embryogenesis. This article discusses pathogenesis, clinical picture, diagnosis treatment of these syndromes. Some illustrations used this copied from other resources, rights authors respected not vi...
