Delineation of the Genetic Architecture and Clinical Polymorphism of 3q29 Duplication Syndrome: A Review of the Literature and a Report of Two Novel Patients With Single-Gene BDH1 Duplications.

Background: Chromosome 3q29 duplication syndrome is a rare chromosomal disorder with a frequency of 1:5000 in patients with a neurodevelopmental phenotype. The syndrome is characterized by phenotypic polymorphism and reduced penetrance.

Methods: Patients were investigated by performing a cytogenetic analysis of GTG-banded metaphases, aCGH with the SurePrint G3 Human CGH Microarray 8×60K, qPCR, FISH, and WES.

Evolution of dispersal in river networks.

Evolution of dispersal is a fascinating topic at the intersection of ecology and evolutionary dynamics that has generated many challenging problems in the analysis of reaction-diffusion equations. Early results indicated that lower random diffusion rates are generally beneficial. However, in riverine environments with downstream drift, high diffusion may be optimal, depending on downstream boundary conditions.

Aberrant methylation of placental development genes in chorionic villi of spontaneous abortions with trisomy 16.

In humans, aneuploidy is incompatible with the birth of healthy children and mainly leads to the death of embryos in the early stages of development in the first trimester of pregnancy. Trisomy 16 is the most common aneuploidy among spontaneous abortions of the first trimester of pregnancy. However, the mechanisms leading to the death of embryos with trisomy 16 remain insufficiently investigated.

Morphological and molecular analysis of rose cultivars from the Grandiflora and Kordesii garden groups.

The breeding of remontant rose cultivars that are resistant to diseases and adverse conditions, with high decorative value and continuous flowering is the most important task during work with the gene pool of garden roses. Currently, intercultivar hybridization within a single garden group has largely outlived its usefulness. It is necessary to breed for highly decorative forms or cultivars that have outstanding resistance, morphological characters and patterns of seasonal rhythms, and use these plants as parental forms in further breeding.

The role of iNOS inhibition in the mechanism of the cardioprotective effect of new GABA and glutamic acid derivatives in the model of acute alcoholic myocardial injury in rats.

The cardioprotective effects of new derivatives of glutamic acid (glufimet) and GABA (mefargin) were studied in rats exposed to acute alcohol intoxication (AAI) under conditions of selective blockade of inducible NO-synthase (iNOS). AAI induced a pronounced decrease in the contractile function of the myocardium during exercise tests (load by volume, test for adrenoreactivity, isometric exercise), caused mitochondrial dysfunction and increased processes of lipid peroxidation (LPO) in heart cells. A decrease in NO production during iNOS inhibition and AAI improved the respiratory function of mitochondria, a decreased the level of LPO products, and increased mitochondrial superoxide dismutase activity of heart cells.
