Location of Tandem Repeats on Wheat Chromosome 5B and the Breakpoint on the 5BS Arm in Wheat Translocation T7BS.7BL-5BS Using Single-Copy FISH Analysis

Plants, 2022
Wheat (Triticum aestivum L.) is rich in tandem repeats, and this is helpful in studying its karyotypic evolution. Some tandem repeats have not been assembled into the wheat genome sequence.

Median inverse problem and approximating the number of $k$-median inverses of a permutation

, 2011
We introduce the "Median Inverse Problem" for metric spaces. In particular, having a permutation $\pi$ in the symmetric group $S_n$ (endowed with the breakpoint distance), we study the set of all $k$-subsets $\{x_1,...,x_k\}\subset S_n$ for which $\pi ...

Microhomology-mediated mechanisms underlie non-recurrent disease-causing microdeletions of the FOXL2 gene or its regulatory domain [PDF]

, 2013
Genomic disorders are often caused by recurrent copy number variations (CNVs), with nonallelic homologous recombination (NAHR) as the underlying mechanism.

Case report: Identification of a novel triplication of alpha-globin gene by the third-generation sequencing: pedigree analysis and genetic diagnosis

Hematology, 2023
Background Thalassemia, a common autosomal hereditary blood disorder worldwide, mainly contains α- and β-thalassemia. The α-globin gene triplicates allele is harmless for carriers, but aggravates the phenotype of β-thalassemia.

Lazy Probabilistic Model Checking without Determinisation [PDF]

, 2015
The bottleneck in the quantitative analysis of Markov chains and Markov decision processes against specifications given in LTL or as some form of nondeterministic B\"uchi automata is the inclusion of a determinisation step of the automaton under ...

Relative growth of the semi-terrestrial crab Pachygrapsus marmoratus: an information-theory approach

Scientia Marina, 2007
The patterns of allometric growth of the grapsid crab Pachygrapsus marmoratus were investigated with an information-theoretic approach. This approach is beneficial, more robust, and may reveal more information than the classical approaches (e.g ...

Norovirus Recombination in ORF1/ORF2 Overlap

Emerging Infectious Diseases, 2005
Norovirus (NoV) genogroups I and II (GI and GII) are now recognized as the predominant worldwide cause of outbreaks of acute gastroenteritis in humans. Three recombinant NoV GII isolates were identified and characterized, 2 of which are unrelated to any ...

Case Report: A prenatal case with sex discordance between non-invasive prenatal testing and fetal genetic testings due to maternal rare chromosome karyotype

Frontiers in Genetics
BackgroundNon-invasive prenatal testing (NIPT), which made use of cell-free DNA (cffDNA) in maternal blood, was currently being applied all over the world for the detection of common chromosome abnormalities.

On pairwise distances and median score of three genomes under DCJ [PDF]

, 2012
In comparative genomics, the rearrangement distance between two genomes (equal the minimal number of genome rearrangements required to transform them into a single genome) is often used for measuring their evolutionary remoteness.

Breakpoints for intravenously used cephalosporins in Enterobacteriaceae—EUCAST and CLSI breakpoints [PDF]

Clinical Microbiology and Infection, 2008
It has long been acknowledged that the cephalosporin breakpoints used in most European countries and the USA fail to detect many or most extended spectrum beta-lactamases (ESBLs) in Enterobacteriaceae and that all ESBLs are clinically significant. Therefore, microbiological laboratories have undertaken not only regular cephalosporin susceptibility ...
