GIS-based support for the complex botanical studies at the Molnieboi Spur, Altai [PDF]
arXiv, 2015 The Molnieboi Spur is located at the northwestern margin of the Katun Range, the high-mountain part of the Altai Mountains. Unique geological and geophysical characteristics of the Molnieboi Spur made it an attractive target for complex botanical studies including botanical, soil, geological, geochemical, geophysical, radiation, and soil gas surveys ...

Chromosomal Gains and Losses in Uveal Melanomas Detected by Comparative Genomic Hybridization [PDF]
, 1994 Eleven uveal melanomas were analyzed using comparative genomic hybridization (CGH). The most abundant genetic changes were loss of chromosome 3, overrepresentation of 6p, loss of 6q, and multiplication of 8q.

Extended Growth Curves for the Wolf‐Hirschhorn Syndrome (4p‐)
American Journal of Medical Genetics Part A, EarlyView.ABSTRACT Wolf‐Hirschhorn syndrome (WHS) is a rare, highly variable contiguous gene deletion syndrome caused by deletions of the distal portion of the short arm of chromosome 4. Individuals with this disorder have prenatal onset of poor growth of all dimensions, along with neurological manifestations, developmental disability, and distinctive facial ...

Development and characterization of Brassica juncea fruticulosa introgression lines exhibiting resistance to mustard aphid [PDF]
, 2017 Background: Mustard aphid is a major pest of Brassica oilseeds. No source for aphid resistance is presently available in Brassica juncea . A wild crucifer, Brassica fruticulosa is known to be resistant to mustard aphid. An artificially synthesized amphiploid, AD-4 (B. fruticulosa x B. rapa var. brown sarson) was developed for use as a bridge species to

Painting of human chromosomes with probes generated from hybrid cell lines by PCR with Alu and L1 primers [PDF]
, 1990 Specific amplification of human sequences of up to several kb length has recently been accomplished in man-hamster and man-mouse somatic hybrid cell DNA by IRS-PCR (interspersed repetitive sequence — polymerase chain reaction).

Cohesins: Crossroad Between Cornelia de Lange Spectrum and Cancer Predisposition
American Journal of Medical Genetics Part A, EarlyView.ABSTRACT The cohesin complex plays crucial roles in DNA repair, chromatid separation, and gene transcription regulation. Pathogenic variants in cohesins or dysfunctional transcriptional regulators lead to cohesinopathies, a broader group of disorders including Cornelia de Lange Spectrum (CdLSp), for which the prevalence of cancer cases remains unclear.

Chromosomal Aberrations in 224 Couples with Recurrent Pregnancy Loss
Journal of Human Reproductive Sciences, 2020 Background: Recurrent pregnancy loss (RPL) is a major reproductive health issue, affecting 2%–5% of couples. Genetic factors, mainly chromosomal abnormalities, are the most common cause of early miscarriage accounting for 50%–60% of first trimester ...

American Journal of Medical Genetics Part A, EarlyView.ABSTRACT Genitopatellar syndrome (GPS) and Say‐Barber‐Biesecker‐Young‐Simpson Syndrome (SBBYSS) are clinically distinct neurodevelopmental disorders caused by monoallelic pathogenic variants in KAT6B. In some cases, GPS and SBBYSS features can overlap, determining an intermediate phenotype.
