CATECHOLAMINE SECRETION AND PLOIDY IN PHAEOCHROMOCYTOMA

open access: yesInternational Journal of Clinical Practice, 2000
SUMMARYThe aim was to evaluate 24 hr urine catecholamine, HMMA and HVA excretion in relation to ploidy in phaeochromocytoma. Data from five diploid and nine tetraploid tumours showed a significant reduction in urine noradrenaline (p=0.02) and HMMA (p=0.03) in diploid tumours but no difference in adrenaline, dopamine and HVA excretion using the Mann ...

Impacts of Inorganic Arsenic Exposure on Genetic Stability of Human Mesenchymal Stromal Cells

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Human mesenchymal stem/stromal cells (hMSCs) can differentiate into mesoderm‐type cells, making them suitable candidates for tissue repair therapies. However, their relatively low frequency in adult tissue necessitates ex vivo expansion prior to regenerative medicine applications, and therefore, long‐term hMSC genetic stability during ...

The impact of one-decade ecological disturbance on genetic changes : a study on the brine shrimp Artemia urmiana from Urmia Lake, Iran [PDF]

open access: yes, 2019
Urmia Lake, the largest natural habitat of the brine shrimp Artemia urmiana, has progressively desiccated over the last two decades, resulting in a loss of 80% of its surface area and producing thousands of hectares of arid salty land.

De Novo Whole Genome Assemblies of Unusual Case‐Making Caddisflies (Trichoptera) Highlight Genomic Convergence in the Composition of the Major Silk Gene (h‐fibroin)

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
The major silk gene, h‐fibroin, was annotated in high‐quality genomes of two unusual case‐making Trichoptera. H‐Fibroin of Limnocentropus insolitus shows a similar amino acid composition to other case‐making species, while the amino acid composition of h‐fibroin of Phryganopsyche brunnea resembles that of retreat‐making species.

Genome size variation and polyploidy incidence in the alpine flora from Spain

open access: yesAnales del Jardín Botánico de Madrid, 2013
The interest to study genome evolution, in particular genome size variation and polyploid incidence, has increased in recent years. Still, only a few studies have been focused at a community level.

A comparative study of the physiological responses of chronically stressed diploid and triploid Atlantic salmon (Salmo salar) [PDF]

open access: yes, 2022
Rømt oppdrettslaks (Salmo salar) regnes for å være en av de største truslene som påføres ville populasjoner av Atlantisk laks grunnet introgressiv hybridisering. Dette kan unngås ved å indusere sterilitet i oppdrettslaksen, noe som er mulig i kommersiell

Variance of ploidy in Candida albicans [PDF]

open access: yesJournal of Bacteriology, 1982
Determination of ploidy was performed on isolates of Candida albicans from clinical sources by measuring nuclear DNA content with fluorescent microscope photometry. By this criterion and UV irradiation survival experiments, haploid, diploid, and tetraploid strains were identified in this organism.

Protein Post‐Translational Modification‐Mediated Control of Type I Interferon Cascade Signaling

open access: yesMedicine Bulletin, EarlyView.
ABSTRACT Type I interferons (IFN‐Is) constitute the primary defense mechanism against pathogenic infections in the human body. The antiviral signaling mediated by IFN‐I is integral to the host immune response. Nevertheless, an imbalance in IFN‐I function can perturb the organism’s homeostasis. Consequently, it is imperative for the body to meticulously

Disentangling relationships in Euphorbia agraria s.l. (Euphorbiaceae) in south‐east Europe: One or two species?

open access: yesTAXON, EarlyView.
Abstract We explored the diversification of the south‐eastern and eastern European Euphorbia agraria s.l. applying molecular (amplified fragment length polymorphism [AFLP] fingerprinting and sequencing of the nuclear ribosomal internal transcribed spacer [ITS]), cytogenetic (relative genome size [RGS] estimations) and morphometric methods.
