Study of SNP 775C>T polymorphism within the bovine ITGB2 gene in Polish Black-and-White cattle and in local breeds of cattle

open access: yesCzech Journal of Animal Science, 2007
The present study addresses the characteristics of the frequency and segregation of alleles determining the SNP 775C>T polymorphism within the bovine ITGB2 gene in the Black-and-White cattle population as well as in two endemic breeds of Polish Red ...

A new familial form of a late-onset, persistent hyperinsulinemic hypoglycemia of infancy caused by a novel mutation in KCNJ11. [PDF]

open access: yes, 2017
The ATP-sensitive potassium channel (KATP) functions as a metabo-electric transducer in regulating insulin secretion from pancreatic β-cells. The pancreatic KATP channel is composed of a pore-forming inwardly-rectifying potassium channel, Kir6.2, and a ...

Purely competitive evolutionary dynamics for games [PDF]

open access: yes, 2012
We introduce and analyze a purely competitive dynamics for the evolution of an infinite population subject to a 3-strategy game. We argue that this dynamics represents a characterization of how certain systems, both natural and artificial, are governed ...

Production of α1,3-galactosyltransferase-deficient pigs [PDF]

open access: yes, 2003
The enzyme α1,3-galactosyltransferase (α1,3GT or GGTA1) synthesizes α1,3galactose (α1,3Gal) epitopes (Galα1,3Galβ1,4GlcNAc-R), which are the major xenoantigens causing hyperacute rejection in pig-to-human xenotransplantation.

Detection of A2143G, A2142C, and A2142G Point Mutations with Real-Time PCR in Stool Specimens from Children Infected with Helicobacter pylori

open access: yesDiagnostics, 2022
Reports have indicated an increasing prevalence of clarithromycin resistance in children relative to adults. Thus, it is important to investigate primary clarithromycin resistance before therapy to avoid treatment failure.

Point Mutation Rate of Bacteriophage ΦX174 [PDF]

open access: yesGenetics, 2009
Abstract The point mutation rate of phage ΦX174 was determined using the fluctuation test. After identifying the genetic changes associated with the selected phenotype, we obtained an estimate of 1.0 × 10−6 substitutions per base per round of copying, which is consistent with Drake's rule (0.003 mutations per genome per round of copying ...

Effects of Somatic Mutations Are Associated with SNP in the Progression of Individual Acute Myeloid Leukemia Patient: The Two-Hit Theory Explains Inherited Predisposition to Pathogenesis [PDF]

open access: yesGenomics & Informatics, 2013
This study evaluated the effects of somatic mutations and single nucleotide polymorphisms (SNPs) on disease progression and tried to verify the two-hit theory in cancer pathogenesis.

Hot-Spot-Specific Probe (HSSP) for Rapid and Accurate Detection of KRAS Mutations in Colorectal Cancer

open access: yesBiosensors, 2022
Detection of oncogene mutations has significance for early diagnosis, customized treatment, treatment progression, and drug resistance monitoring. Here, we introduce a rapid, sensitive, and specific mutation detection assay based on the hot-spot-specific

Evolution of genome size in asexual populations

open access: yes, 2015
Genome sizes have evolved to vary widely, from 250 bases in viroids to 670 billion bases in amoeba. This remarkable variation in genome size is the outcome of complex interactions between various evolutionary factors such as point mutation rate ...
