Curcumin protects against manganese-induced neurotoxicity in rat by regulating oxidative stress-related gene expression via H3K27 acetylation

open access: yesEcotoxicology and Environmental Safety, 2022
Long-term manganese exposure causes a neurodegenerative disorder referred to as manganese poisoning, but the mechanism remains unclear and no specific treatment is available.

Severity scoring of manganese health effects for categorical regression [PDF]

open access: yes, 2016
Characterizing the U-shaped exposure response relationship for manganese (Mn) is necessary for estimating the risk of adverse health from Mn toxicity due to excess or deficiency. Categorical regression has emerged as a powerful tool for exposure-response

Coordination-driven magnetic-to-nonmagnetic transition in manganese doped silicon clusters [PDF]

open access: yesPhys. Rev. B 88, 115425 (2013), 2013
The interaction of a single manganese impurity with silicon is analyzed in a combined experimental and theoretical study of the electronic, magnetic, and structural properties of manganese-doped silicon clusters. The structural transition from exohedral to endohedral doping coincides with a quenching of high-spin states.

Poison Attack and Defense on Deep Source Code Processing Models [PDF]

open access: yesarXiv, 2022
In the software engineering community, deep learning (DL) has recently been applied to many source code processing tasks. Due to the poor interpretability of DL models, their security vulnerabilities require scrutiny. Recently, researchers have identified an emergent security threat, namely poison attack. The attackers aim to inject insidious backdoors

A Proposal to Measure the Quasiparticle Poisoning Time of Majorana Bound States [PDF]

open access: yesPhys. Rev. B 89, 140505 (2014), 2013
We propose a method of measuring the fermion parity lifetime of Majorana fermion modes due to quasiparticle poisoning. We model quasiparticle poisoning by coupling the Majorana modes to electron reservoirs, explicitly breaking parity conservation in the system. This poisoning broadens and shortens the resonance peak associated with Majorana modes. In a

Manganese toxicity with ephedrone abuse manifesting as parkinsonism: a case report

open access: yesJournal of Medical Case Reports, 2012
Introduction Neurologic consequences of manganese toxicity have been recognized since 1837. A new form of presumed manganese poisoning has been reported in drug-addicted persons from Eastern Europe and the Baltic states who have intravenously injected ...

Beneficial effect of Mentha spicata essential oil on lead and manganese induced nephrotoxicity and oxidative damage in rat kidney

open access: yesNotulae Scientia Biologicae, 2020
Our work focused on the impact of chronic lead acetate and manganese chloride poisoning on renal function in Wistar rats. It also tested the efficacy of the essential oil extracted from (Mentha spicata) spearmint in reversing these effects by treating ...

Accumulative Poisoning Attacks on Real-time Data [PDF]

open access: yesarXiv, 2021
Collecting training data from untrusted sources exposes machine learning services to poisoning adversaries, who maliciously manipulate training data to degrade the model accuracy. When trained on offline datasets, poisoning adversaries have to inject the poisoned data in advance before training, and the order of feeding these poisoned batches into the ...

Advances in study of relationships between gene polymorphisms and manganese poisoning

open access: yes环境与职业医学
Occupational manganese poisoning is one of the most important occupational diseases in China, and it can cause different degrees of damage to various organs of the body, among which neurotoxicity is particularly obvious.

Manganese nanoclusters and nanowires on GaAs surfaces [PDF]

open access: yes, 2002
We have computed the local magnetic moments of manganese and neighboring arsenic for various cluster configurations on the (001) surface of GaAs bulk crystal using a cluster of 512 atoms. We obtained for manganese a substantial local magnetic moment of 3.66 Bohr magnetons for all cases considered.
