Rapid mapping of chromosomal breakpoints: from blood to BAC in 20 days [PDF]

open access: yes, 2009
Structural chromosome aberrations and associated segmental or chromosomal aneusomies are major causes of reproductive failure in humans. Despite the fact that carriers of reciprocal balanced translocation often have no other clinical symptoms or ...

CircTP53/USP10/p53 signaling Axis as a Novel Regulator of Progression and Prognosis of Head and Neck Squamous Cell Carcinoma

open access: yesAdvanced Science, EarlyView.
The study identifies a novel circular RNA derived from the TP53 gene (circTP53), which is upregulated in HNSCC and correlates with poor patient prognosis. It demonstrates that circTP53 promotes HNSCC progression by interacting with USP10, stabilizing both proteins, enhancing deubiquitination of p53, and thereby influencing tumor growth, with its ...

Giemsa-based chromosome staining and comparative fluorescent banding pattern in five valuable Indian plant species

open access: yesCaryologia
This study presents repeatable enzymatic maceration and air drying (EMA)-based chromosome preparation methods in five valuable Indian plant species namely Allium cepa, Allium sativum, Nigella sativa, Trigonella foenum-graecum, and Aloe vera.

Evidence for TTAGG telomere repeats and rRNA gene clusters in leafhoppers of the genus Alebra (Hemiptera: Auchenorrhyncha: Cicadellidae)

open access: yesEuropean Journal of Entomology, 2015
The leafhopper genus Alebra Fieber, 1872 comprises a complex of morphologically similar species. The chromosome complements (karyotypes) of five Alebra species, i.e. A. albostriella, A. coryli, A. viridis, A. wahlbergi and a new, yet undescribed species,

Interchromatidal central ridge and transversal symmetry in early metaphasic human chromosome one [PDF]

open access: yesarXiv, 2008
The topographic structure of Giemsa banded (G-banded) early metaphase human chromosomes adsorbed on glass was analyzed by atomic force microscope using amplitude modulation mode [AM-AFM]. Longitudinal height measurements for early metaphasic human chromosomes showed a central ridge that was further characterized by transversal height measurements.

Clonal karyotype evolution involving ring chromosome 1 with myelodysplastic syndrome subtype RAEB-t progressing into acute leukemia [PDF]

open access: yes, 2006
s Karyotypic evolution is a well-known phenomenon in patients with malignant hernatological disorders during disease progression. We describe a 50-year-old male patient who had originally presented with pancytopenia in October 1992.

Manipulation of Oxygen Tension in Damaged Regions via Hypoxia‐Induced IPN Hydrogel Microspheres for Intervertebral Disc Regeneration

open access: yesAdvanced Science, EarlyView.
A novel interpenetrating network hydrogel microsphere (NSC‐Exos@HIMS) is developed to manipulate oxygen tension in damaged regions and recruit endogenous stem cells. In vitro and in vivo results show that NSC‐Exos@HIMS maintains the hypoxia microenvironment for up to 5 days, which triggers nucleus pulposus cell‐like differentiation and enhanced ECM ...

Comparative cytogenetics of some marsupial species (Didelphimorphia, Didelphidae) from the Amazon basin

open access: yesComparative Cytogenetics, 2017
We investigated the karyotype of 18 didelphid species captured at 13 localities in the Brazilian Amazon, after conventional staining, C-banding, Ag-NOR and fluorescent in situ hybridization (FISH) using the 18S rDNA probe.

Karyotype evolution in progress: A new diploid number in Belostoma candidulum (Heteroptera: Belostomatidae) from Argentina leading to new insights into its ecology and evolution [PDF]

open access: yes, 2014
A novel chromosome complement (2n = 14 = 12 + XY/XX; male/female sex chromosomes), male meiosis behaviour, heterochromatin characterization, and frequency and distribution of chiasmata are described for the first time in specimens from a natural ...

Accounting for ALA Natural Mutations Enhances the Efficiency of Graphene Oxide Nanopriming in Bar‐Modified Arabidopsis

open access: yesAdvanced Science, EarlyView.
Nanopriming enhances plant resilience to environmental challenges; however, its effectiveness across diverse genetic backgrounds, including genetic modifications and natural variations, remains uncertain. These findings demonstrate that nanopriming improves efficacy when natural genetic variations are considered, particularly in genetically modified ...
