Molecular bases of insect odorant receptor function: specificity and evolution

open access: yesBiological Reviews, EarlyView.
ABSTRACT Insect odorant receptors (ORs) are a class of chemoreceptors that insects use to detect volatile cues in their environment. In recent years, major advances in the field of structural biology have made it possible to obtain the first structures of insect ORs.

A family of chemoreceptors in Tribolium castaneum (Tenebrionidae: Coleoptera). [PDF]

open access: yesPLoS ONE, 2007
Chemoperception in invertebrates is mediated by a family of G-protein-coupled receptors (GPCR). To date nothing is known about the molecular mechanisms of chemoperception in coleopteran species.

Modeling Supports Combinatorial Effects Between Pharmacological and Non‐Pharmacological Interventions to Prevent Opioid‐Induced Cardiac Arrest

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Few studies have quantified the effects of non‐pharmacological interventions (e.g., rescue breathing) in the setting of community opioid overdose. We extended a previously validated model for opioid antagonists by incorporating the mechanism of rescue breathing, and quantified combinatorial effects between rescue breathing and various formulations of ...

Identification of Cbp1, a c-di-GMP Binding Chemoreceptor in Azorhizobium caulinodans ORS571 Involved in Chemotaxis and Nodulation of the Host Plant

open access: yesFrontiers in Microbiology, 2019
Cbp1, a chemoreceptor containing a PilZ domain was identified in Azorhizobium caulinodans ORS571, a nitrogen-fixing free-living soil bacterium that induces nodule formation in both the roots and stems of the host legume Sesbania rostrata.

A Case for Hydrogen Sulfide Metabolism as an Oxygen Sensing Mechanism

open access: yesAntioxidants, 2021
The ability to detect oxygen availability is a ubiquitous attribute of aerobic organisms. However, the mechanism(s) that transduce oxygen concentration or availability into appropriate physiological responses is less clear and often controversial.

Ketogenic diet for infantile epileptic spasms

open access: yesEpilepsia Open, EarlyView.
Abstract Approximately half of all cases of Infantile Epileptic Spasms Syndrome (IESS) do not respond to vigabatrin and hormonal therapies. There is no clear consensus as to the second‐line therapy for IESS. Ketogenic diet (KD) has emerged as an effective treatment for certain drug‐resistant epilepsies and in many cases of IESS.

Signalling mechanisms of long term facilitation of breathing with intermittent hypoxia. [PDF]

open access: yes, 2013
Intermittent hypoxia causes long-term facilitation (LTF) of respiratory motor nerve activity and ventilation, which manifests as a persistent increase over the normoxic baseline for an hour or more after the acute hypoxic ventilatory response.

The Gluopsins: Opsins without the Retinal Binding Lysine

open access: yesCells, 2022
Opsins allow us to see. They are G-protein-coupled receptors and bind as ligand retinal, which is bound covalently to a lysine in the seventh transmembrane domain. This makes opsins light-sensitive.

Ecotoxicological Evaluation of the Antimicrobial Butylparaben in Edaphic Organisms Using Multiple Biomarkers

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Butylparaben (BuP) recurrently contaminates soils worldwide, mainly by incorporating sewage sludge into cultivated areas, using wastewater in irrigation, and leaching contaminated soils. However, there are few studies on the ecotoxicological effects of this paraben on edaphic organisms.
