Reduced mitochondrial complex II activity enhances cell death via intracellular reactive oxygen species in STHdhQ111 striatal neurons with mutant huntingtin

open access: yesJournal of Pharmacological Sciences, 2021
Huntington's disease (HD) is an inherited neurodegenerative disorder caused by CAG repeat expansion in the huntingtin (HTT) gene. Here, we examined the effects of antioxidants on 3-nitropropionic acid (3-NP; a mitochondrial complex II inhibitor)-induced ...

Identification of cyclin D1 as a major modulator of 3-nitropropionic acid-induced striatal neurodegeneration

open access: yesNeurobiology of Disease, 2022
Mitochondria dysfunction occurs in the aging brain as well as in several neurodegenerative disorders and predisposes neuronal cells to enhanced sensitivity to neurotoxins.

Inhibition of Brain GTP Cyclohydrolase I Attenuates 3-Nitropropionic Acid-Induced Striatal Toxicity: Involvement of Mas Receptor/PI3k/Akt/CREB/ BDNF Axis

open access: yesFrontiers in Pharmacology, 2021
GTP cyclohydrolase I (GTPCH I) is the rate-limiting enzyme for tetrahydrobiopterin (BH4) biosynthesis; the latter is an essential factor for iNOS activation that contributes neuronal loss in Huntington’s disease (HD).

ANTIOXIDANTS AND ANTI-INFLAMMATION POTENTIALOF AMARANTHUS VIRIDIS LINN AGAINST 3-NP-INDUCED HUNTINGTONS DISEASE IN RATS

open access: yesInternational Journal of Advanced Research, 2022
Huntingtons disease (HD) is an autosomal dominant neurodegenerative disease. Accordingly, 3-nitropropionic acid (3-NP) has been found to effectively produce HD-like symptoms. Amaranthus viridis Linn (HAEAV), popularly known in Chauraiya in Hindi, may act as a neuroprotective agent in vitro andin vivo.

Optical waveguide amplifiers based on NaYF_4: Er^3+, Yb^3+ NPs-PMMA covalent-linking nanocomposites

open access: yesOptical Materials Express, 2015
NaYF4: Er3+, Yb3+ nanoparticles (NPs) were synthesized by using a high temperature thermal decomposition approach. Under a 980 nm laser excitation, intense emission at 1.53 μm from NaYF4: Er3+,Yb3+ NPs was obtained. NaYF4: Er3+, Yb3+ NPs-PMMA covalent-linking nanocomposite was prepared by copolymerization of the oleic acid-modified NaYF4: Er3+, Yb3 ...

Delayed Onset and Reduced Cognitive Deficits through Pre-Conditioning with 3-Nitropropionic Acid is Dependent on Sex and CAG Repeat Length in the R6/2 Mouse Model of Huntington's Disease. [PDF]

open access: yes, 2016
BACKGROUND: Impairments in energy metabolism are implicated in Huntington's disease (HD) pathogenesis. Reduced levels of the mitochondrial enzyme succinate dehydrogenase (SDH), the main element of complex II, are observed post mortem in the brains of HD ...

A Quality Improvement Initiative to Standardize Pneumocystis jirovecii Pneumonia Prophylaxis in Pediatric Patients With Solid Tumors

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric patients with extracranial solid tumors (ST) receiving chemotherapy are at an increased risk for Pneumocystis jirovecii pneumonia (PJP). However, evidence guiding prophylaxis practices in this population is limited. A PJP‐related fatality at our institution highlighted inconsistent prescribing approaches and concerns about

RSM-BBD Optimization of Fenton-Like Degradation of 4-Nitrophenol Using Magnetite Impregnated Kaolin

open access: yesAir, Soil and Water Research, 2020
In this work, we have reported a low-cost and environmentally friendly Fe 3 O 4 -modified activated kaolin (AK-Fe 3 O 4 ) composite for efficient Fenton-like degradation of 4-nitrophenol (4-NP) and optimization of the degradation variables. The AK-Fe 3 O

Role of aquaporin-3 in hyperosmolarity-induced apoptosis of rat nucleus pulposus cells in vitro

open access: yesDi-san junyi daxue xuebao, 2020
Objective To investigate the role of aquaporin-3 (AQP-3) in hyperosmolarity-induced apoptosis of cultured rat nucleus pulposus (NP) cells. Methods Rat NP cells were cultured under different osmotic pressures (330 and 550 mOsm/kg), and the proliferation ...
