Reversing Signs of Parkinsonism in a Cell Model Using Mitochondria-Targeted Organoiridium Catalysis.

We report the application of organoiridium complexes as catalytic agents for the detoxification of biogenic reactive aldehyde species (RASP), which are implicated in the pathogenesis of neurodegenerative disorders. We show that Ir complexes functionalized with phosphonium cations localize selectively in the mitochondria and have better cellular retention compared to that of their parent Ir species. In a cell model for Parkinsonism, the mitochondria-targeted iridium catalysts exhibited superior cell protecting abilities and longer-lasting effects (up to 6 d) than conventional RASP scavengers, which failed to be effective beyond 24 h.

Cellular Attachment Assays to Dissect Molecular Drivers of Epidermal Cell Function.

Cell attachment is the process by which cells interact with their environment, including neighboring cells and the extracellular matrix (ECM). Attachment plays a critical role in maintaining skin integrity, promoting wound healing, and facilitating cellular communication in epidermal cells, such as keratinocytes. However, the many different factors that can influence this mechanism make it challenging to recapitulate in cellular models.

Early Childhood Exposures to Fluorides and Cognitive Neurodevelopment: A Population-Based Longitudinal Study.

It is important to maintain confidence in the risk and benefit balance of major caries-preventive programs using fluoride. The ongoing debate about potential effects of early-life exposures to fluoride on cognitive neurodevelopment requires high-quality scientific evidence. This study aimed to investigate the potential effects of fluoride exposure on cognitive neurodevelopment assessed with the Wechsler Adult Intelligence Scale 4th edition (WAIS-IV) in an Australian population-based sample.

Is the repeat worth it? Optimizing syndromic panel pathogen detection protocols.

Objective: The aim of the study was to compare the cost and clinical impact of repeating BioFire FilmArray gastrointestinal (GI) and respiratory (RP) panel assays with 3 vs 4 pathogen targets positive.

Method: We analyzed 12,027 GI and RP panels to evaluate our retesting policy, which retested panels with 3 or more detected pathogens (3-pathogen protocol) compared with the manufacturer's 4-pathogen (4-pathogen protocol) recommendation. We compared the retesting results, calculated the cost implications, and reviewed the clinical impact on antibiotic prescriptions and patient outcomes.

Long-term changes in soil biological activity and other properties of raised beds in Longan orchards.

Introduction: The Longan fruit tree of the Vietnam Mekong Delta is grown in raised beds to improve water drainage during the rainy season and can live as long as 100 years.

Objective: This research explores the extent to which the soil microorganisms as well as soil physical and chemical properties of these raised beds degrade over a period of 60 years under traditional management practices.

Materials And Methods: Raised bed topsoil samples at depths of 0-20 cm were obtained from four different Longan orchards raised bed age groups: group 1) 15-25 years (L1-L5); group 2) 26-37 years (L6-L10); group 3) 38-45 years (L11-L15); and group 4) 46-60 years.
