shigellosis is one of the important gastrointestinal bacterial infections, particularly among children of developing countries such as iran. antibiotic susceptibility pattern and genetic typing for epidemiological purposes are of significant issues in shigella infectious control. the aim of this study was to investigate the antibiotic susceptibility and genetic relationship among shigella strai...
To characterize patient-derived xenografts (PDXs) for functional studies, we made whole-genome comparisons with originating breast cancers representative of the major intrinsic subtypes. Structural and copy number aberrations were found to be retained with high fidelity. However, at the single-nucleotide level, variable numbers of PDX-specific somatic events were documented, although they were ...
Multicellular organisms can be regenerated from totipotent differentiated somatic cell or nuclear founders [1-3]. Organisms regenerated from clonally related isogenic founders might a priori have been expected to be phenotypically invariant. However, clonal regenerant animals display variant phenotypes caused by defective epigenetic reprogramming of gene expression [2], and clonal regenerant pl...
The plant tissue culture procedures for asexual multiplication of Hancornia speciosa represent an important process facilitating the preservation selected genotypes this threatened species and large-scale production plantlets population reinforcement or other utilization. However, there is no research regarding somaclonal variation at molecular level. This study aimed to evaluate role in geneti...
Ranunculus wallichianus is a medicinally important plant and an endemic species to the Western Ghats of South India. An efficient reliable indirect regeneration protocol system for R. was developed from leaf explants in present investigation. Leaf were cultured on both full-strength half-strength MS (Murashige & Skoog) medium supplemented with different concentrations (0.5 mg L− 1 3.0 1) 2,4-D ...
Toxoplasma gondii is one of the most prevalent parasitic infections in world. Rh, NED and Me49 are of the most prevalent clonal types of the parasite isolated till now. Differences in pathogenicity and virulence of different types have been investigated in different studies. No controlled study was performed to compare the ability of different types to initiate humoral immune response. We inves...
