Craniosynostosis is a disorder characterized by premature closure of cranial sutures, resulting in restricted skull growth perpendicular to the affected suture and compensatory growth in other directions. Over 180 syndromes have been classified under craniosynostosis, of which eight are associated with mutations in the fibroblast growth factor receptor 2 (FGFR2) gene: isolated coronal synostosis, Pfeiffer syndrome, Crouzon syndrome, Apert syndrome, Beare–Stevens syndrome, Jackson–Weiss syndrome, Crouzon syndrome wi [...]

Rauvolfia tetraphylla L. (1753) is an important medicinal species of Apocynaceae, widely used for its rich indole alkaloids and related bioactive compounds. We report the first complete chloroplast genome of R. tetraphylla. The genome exhibits a typical circular quadripartite structure of 155,667 bp, with an overall GC content of 37.8%. The genome comprises a large single-copy (LSC) region of 86,332 bp, a small single-copy (SSC) region of 17,853 bp, and a pair of inverted repeat (IR) regions of 25,741 bp each. A to [...]

The article reveals the variability of the genome of cattle of the local small-numbered domestic Brown Carpathian breed using cytogenetic and molecular genetic polylocus markers, and justifies the need to integrate local breeds into the modern system of agricultural production in accordance with FAO requirements. The work aimed to study the genetic uniqueness of cows of the brown Carpathian breed using cytogenetic and molecular genetic markers. The karyotype of the animals corresponded to the species norm and was 2 [...]

Non-invasive prenatal testing (NIPT) is now standard in prenatal care in many countries, even though it was introduced only about 15 years ago. Due to its rapid adoption into decades-old prenatal care plans, gynecologists, obstetricians, and the general public still struggle to understand the possibilities, benefits, and limitations of NIPT. The biggest challenge facing NIPT is that comprehensive training for healthcare professionals and independent, unbiased information for pregnant women and their families about [...]

Genetically conditioned variation in pollen has been demonstrated to have a substantial influence on reproductive mechanisms and population dynamics. The present study evaluated the genetic variability of 28 pollen samples of Corylus avellana L. using iPBS (Inter Primer Binding Sites Polymorphism) markers 1882 and 2152. The collection of biological material was undertaken at various locations across five European countries, with the objective of capturing a broad spectrum of environmental conditions. The genetic re [...]

Salinity poses a danger to food security; hence, it is necessary to create crop types that can withstand salt to meet the growing demand for food. The goal of the current study was to examine the morphological and biochemical responses of wheat (Triticum aestivum L.) genotypes under salt stress. Salt tolerance in ten wheat cultivars and five selected F1 hybrids was assessed at the germination and seedling stage. Genotypes were assessed for seven traits under control (0 mM NaCl) and salinity stress (150, 200, and 25 [...]

Diabetes mellitus (DM) is a metabolic disorder resulting from aberrations in insulin secretion or action. Diabetes mellitus still presents as a global health challenge. Conventional diabetes treatment may result in unwanted side effects and/or poor compliance. More personalized and curative approaches to the treatment of DM are required. The review explores recent developments in the fields of genetic and molecular underpinnings of DM, focusing on the revolutionary potential of cell- and Clustered Regularly Intersp [...]

Diabetes mellitus (DM) is widely spread among populations. About 3 of 10 people show the symptoms of this disease. Many factors may cause this illness in both types (type 1 and type 2 DM), mainly attributed to insufficient insulin production in type 1 DM or developing insulin resistance in type 2 DM. Genes that control specific biochemical pathways involving glucose metabolism can interfere with the manifestation of this disease when they undergo genetic changes like KRAS. Investigating the role of KRAS in DM. Abou [...]

Male infertility is a growing concern worldwide, with almost half of infertility cases being male, and the trend is rising in China as a result of multifaceted genetics-environment interaction. Important breakthroughs have been made in identifying mutations in annotated protein-coding genes associated with male infertility. However, a significant part of the human genome, namely non-coding DNA, has not yet been explored. Recent breakthroughs in the realm of high-throughput genomic technologies have unveiled the ind [...]

Advances in antiretroviral therapy (ART) have normalized the life expectancy of people living with HIV (PLWH) but have been linked to a premature presentation of age-related comorbidities, including cancer. Telomere length (TL) is a marker of cellular aging and was investigated in blood leukocytes from 78 PLWH on ART, compared with 163 HIV-uninfected controls. The PLWH group was stratified into three subgroups: HIV-only (n = 57), HIV with AIDS-defining cancer (ADC, n = 9), and HIV with NADC (n = 12). Quantitative p [...]
