Acyclic Nucleoside Phosphonates As Potential Inhibitors Of Plasmodium Falciparum Egress

Chemistry – A European Journal, EarlyView.
Exploration of the chemistry of acyclic nucleoside phosphonates allowed us to study structural diversity from the hit compound; biological evaluation and molecular docking were performed to decipher key interactions with the putative target. Abstract The emergence of drug‐resistant Plasmodium strains requires the development of novel antimalarial ...

Brain network and energy imbalance in Parkinson’s disease: linking ATP reduction and α-synuclein pathology

Frontiers in Molecular Neuroscience
Parkinson’s disease (PD) involves the disruption of brain energy homeostasis. This encompasses broad-impact factors such as mitochondrial dysfunction, impaired glycolysis, and other metabolic disturbances, like disruptions in the pentose phosphate ...

Nucleotides: Structure and Properties [PDF]

, 2005
Nucleotides consist of a nitrogen-containing base, a five-carbon sugar, and one or more phosphate groups. Cells contain many types of nucleotides, which play a central role in a wide variety of cellular processes, including metabolic regulation and the ...

Identification of Candidate Blood Biomarkers of Recombinant Human Erythropoietin Administration Using Targeted Polar Metabolomics by HILIC‐MS/MS

Drug Testing and Analysis, EarlyView.
Using targeted HILIC‐MS/MS metabolomics, inosine and hypoxanthine were identified as potential biomarkers of EPO administration. Their consistent and sensitive plasma responses highlight their promise for inclusion in the Athlete Biological Passport (ABP), warranting further investigation to enhance anti‐doping detection strategies. ABSTRACT Increasing

Fatty Acid Oxidation and Meiotic Resumption in Mouse Oocytes [PDF]

, 2009
We have examined the potential role of fatty acid oxidation (FAO) in AMP-activated protein kinase (AMPK)-induced meiotic maturation. Etomoxir and malonyl CoA, two inhibitors of carnitine palmitoyl transferase-1 (CPT1), and thus FAO, blocked meiotic ...

Interpretation of in vitro concentration‐response data for risk assessment and regulatory decision‐making: Report from the 2022 IWGT quantitative analysis expert working group meeting

Environmental and Molecular Mutagenesis, EarlyView.
Abstract Quantitative risk assessments of chemicals are routinely performed using in vivo data from rodents; however, there is growing recognition that non‐animal approaches can be human‐relevant alternatives. There is an urgent need to build confidence in non‐animal alternatives given the international support to reduce the use of animals in toxicity ...

6-thioguanine treatment in inflammatory bowel disease: A critical appraisal by a European 6-TG working party [PDF]

, 2006
Recently, the suggestion to use 6-thioguanine (6-TG) as an alternative thiopurine in patients with inflammatory bowel disease (IBD) has been discarded due to reports about possible (hepato) toxicity. During meetings arranged in Vienna and Prague in 2004,

Severity of effect considerations regarding the use of mutation as a toxicological endpoint for risk assessment: A report from the 8th International Workshop on Genotoxicity Testing (IWGT)

Environmental and Molecular Mutagenesis, EarlyView.
Abstract Exposure levels without appreciable human health risk may be determined by dividing a point of departure on a dose–response curve (e.g., benchmark dose) by a composite adjustment factor (AF). An “effect severity” AF (ESAF) is employed in some regulatory contexts.

A combinatorial approach of Proteomics and Systems Biology in unravelling the mechanisms of acute kidney injury (AKI): involvement of NMDA receptor GRIN1 in murine AKI [PDF]

, 2013
BACKGROUND: Acute kidney injury (AKI) is a frequent condition in hospitalised patients undergoing major surgery or the critically ill and is associated with increased mortality.
