pamfit: A new R package for spatially resolved analysis of Imaging PAM photosynthesis–irradiance light curve parameters

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Imaging Pulse Amplitude Modulation (PAM) fluorometry allows spatially resolved measurements of Photosystem II (PSII) fluorescence kinetics through time without disturbing study organisms or their environments. In particular, the use of photosynthesis–irradiance curves (P–I curves) provides detailed information on PSII quantum efficiency ...

Exploring Thermal and Mechanical Strains During Laying Down Process in Fused Filament Fabrication

open access: yesMacromolecular Materials and Engineering, EarlyView.
This study analyzes strain evolution and thermal behavior during FFF of PLA using strain gauges and infrared imaging. Microstrain levels depend on printing conditions, with adhesion‐induced compression during cooling and peak strains in early layers. Microtomography shows minimal porosity, while thermal imaging reveals rapid heat penetration, strong ...

Emerging Therapeutic Strategies in Anti‐Aging Medicine: A Comprehensive Review

open access: yesMedicine Bulletin, EarlyView.
ABSTRACT Aging is orchestrated by interconnected hallmarks such as genomic instability, mitochondrial dysfunction, cellular senescence, and disrupted intercellular communication, which collectively drive chronic disease progression. Recent advances have expanded therapeutic opportunities to include pharmacological agents, gene and epigenome editing ...

Effect on Dyskinesia of the Early Combination of Amantadine to Levodopa‐Therapy in Parkinson's Disease: A Randomized, Placebo‐Controlled Study (PREMANDYSK)

open access: yesMovement Disorders, EarlyView.
Abstract Objective Investigate the efficacy of immediate‐release (IR) amantadine in reducing the risk of peak‐dose dyskinesia in early Parkinson's disease (PD) as add‐on to levodopa. Background While the use of amantadine to manage dyskinesia in PD is well supported by controlled clinical trials, data on its efficacy in patients without motor ...
