Magnetic excitation in a new spin gap compound Cu$_2$Sc$_2$Ge$_4$O$_{13}$: Comparison to Cu$_2$Fe$_2$Ge$_4$O$_{13}$ [PDF]

open access: yes, 2006
The compound \CuScGeO is presented as a new member of the family of weakly coupled spin chain and dimer compounds \CuMGeO. Magnetic susceptibility, heat capacity, and neutron inelastic scattering measurements reveal that the compound has the same spin dimer component as \CuFeGeO.

Protective Effect of Prolactin against Methylmercury-Induced Mutagenicity and Cytotoxicity on Human Lymphocytes [PDF]

open access: yes, 2014
Mercury exhibits cytotoxic and mutagenic properties as a result of its effect on tubulin. This toxicity mechanism is related to the production of free radicals that can cause DNA damage.

Developments in Permafrost Science and Engineering in Response to Climate Warming in Circumpolar and High Mountain Regions, 2019–2024

open access: yesPermafrost and Periglacial Processes, Volume 36, Issue 2, Page 167-188, April/June 2025.
ABSTRACT Research in geocryology is currently principally concerned with the effects of climate change on permafrost terrain. The motivations for most of the research are (1) quantification of the anticipated net emissions of CO2 and CH4 from warming and thaw of near‐surface permafrost and (2) mitigation of effects on infrastructure of such warming and

Heavy metal intoxication [PDF]

open access: yes, 2016
Although some debate exists with regards to the subject, elements which are classified under ‘heavy metals’ have come to be those which pose a threat to humans in terms of toxicity.

Targeting signaling pathways in neurodegenerative diseases: Quercetin's cellular and molecular mechanisms for neuroprotection

open access: yesAnimal Models and Experimental Medicine, Volume 8, Issue 5, Page 798-818, May 2025.
Quercetin regulates signaling pathways in neurodegenerative diseases, including NF‐κB, sirtuins, and PI3K/Akt. Studies show quercetin improves symptoms and pathology in neurodegenerative models. The study aims to incorporate laboratory research into practical medical treatment, focusing on quercetin's neuroprotective effects and optimal dosage ...

Compound matrices in systems and control theory [PDF]

open access: yesarXiv, 2021
The multiplicative and additive compounds of a matrix play an important role in several fields of mathematics including geometry, multi-linear algebra, combinatorics, and the analysis of nonlinear time-varying dynamical systems. There is a growing interest in applications of these compounds, and their generalizations, in systems and control theory ...

Anthocyanin Extracts From 11 Superfruits Mitigate Oxidative Stress and Inflammatory Damage in HK‐2 Cells Induced by Cadmium Exposure

open access: yesFood Frontiers, Volume 6, Issue 3, Page 1558-1574, May 2025.
ABSTRACT Cadmium (Cd) pollution has emerged as an escalating threat to human health, with its induced kidney toxicity being closely linked to oxidative stress and inflammation. In this study, we extracted and analyzed primary anthocyanins from 11 superfruits using UPLC‐Triple‐TOF/MS and evaluated their antioxidant capacity through DPPH, ABTS, FRAP, and

Terrestrial organic matter biomarkers as tracers of Hg sources in lake sediments [PDF]

open access: yes, 2010
Terrestrial organic matter (TOM) plays a key role in mercury (Hg) dynamics between watersheds and lakes. In this study we attempts to determine the role of TOM source and quality and not only quantity, in the fate and transport of total Hg (T-Hg) to ...
