A novel plasmid‐based experimental system in Saccharomyces cerevisiae that enables the introduction of 10 different plasmids into cells

open access: yesFEBS Open Bio, Volume 14, Issue 12, Page 1955-1971, December 2024.
We developed the Saccharomyces cerevisiae strains termed Δ10 that exhibit auxotrophic behavior for 10 different nutrients and the plasmids with auxotrophic markers for use in Δ10 strains. Δ10 strains were able to maintain 10 types of plasmids by auxotrophic selection.

Analytical Review on Persian Poppy (Papaver bracteatum Lindl.) as a Native and Economical Medicinal Plant

open access: yesJournal of Medicinal Plants, 2013
Persian poppy or great scarlet poppy (Papaver bracteatum Lindl.) is proposed as a new source of raw material for codeine production and addiction treatment. This species as a native plant is growing in North and West of Iran.

Structural analysis of a ligand‐triggered intermolecular disulfide switch in a major latex protein from opium poppy

open access: yesActa Crystallographica Section D, Volume 80, Issue 9, Page 675-685, September 2024.
Crystal structures of two cysteine‐to‐serine mutants of PR10‐10 help to reveal how a ligand‐induced conformational change is coupled to the formation of intermolecular disulfide bonds in plant pathogenesis‐related family 10 proteins involved in the biosynthesis of benzylisoquinoline alkaloids.Several proteins from plant pathogenesis‐related family 10 ...

Strangers in a foreign land: ‘Yeastizing’ plant enzymes

open access: yesMicrobial Biotechnology, Volume 17, Issue 9, September 2024.
Many plant secondary metabolic enzymes need to be re‐engineered for optimal performance in yeast platforms due to poor adaptation to the foreign cellular environment. We highlight the challenges in ‘yeastizing’ plant enzymes and propose a data‐driven framework for learning the yeastizing rules from natural protein sequence variations.

Pediatric poisoning management: How clinical practice can benefit from forensic approach

open access: yesJournal of Forensic Sciences, Volume 69, Issue 4, Page 1501-1507, July 2024.
Abstract Pediatric population represents the most vulnerable and at risk for unintentional poisoning, with children younger than 6 years old accounting for nearly half of poison exposures. Poisoning is a time‐dependent emergency. The need to reach a scientific agreement on diagnostic protocol and treatment seems to be crucial to reduce morbidity and ...

Opium Price Shocks and Prescription Opioids in the USA*

open access: yesOxford Bulletin of Economics and Statistics, Volume 86, Issue 3, Page 449-484, June 2024.
Abstract We investigate the effect of international opium price shocks on the per capita dispensation of prescription opioids in the USA. Using quarterly county‐level data for 2002q4–2016q4, three main results emerge. First, reductions in opium prices significantly increase the quantity of opioids prescribed, and more so in counties with a larger pre ...

Synthesis, biological evaluation, and utility of fluorescent ligands targeting the μ-opioid receptor [PDF]

open access: yes, 2015
Fluorescently labeled ligands are useful pharmacological research tools for studying receptor localization, trafficking, and signaling processes via fluorescence imaging. They are also employed in fluorescent binding assays. This study is centered on the
