Rapid assessment of fern spore quality using microscale electrical conductivity testing

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Ex situ spore banks are essential for fern conservation and research, yet traditional germination tests for assessing spore quality are time consuming and labor intensive. We explored whether electrical conductivity (EC), a rapid proxy for seed vigor, could offer an efficient alternative for evaluating fern spore quality. Methods Using

Puccinellia maritima, Spartina maritime, and Spartina patens Halophytic Grasses: Characterization of Polyphenolic and Chlorophyll Profiles and Evaluation of Their Biological Activities

open access: yesMolecules, 2019
Halophytic grasses have been recently targeted as possible sources of nutraceutical and medicinal compounds. Nonetheless, few studies have been conducted on the phytochemistry and biological activities of metabolites produced by these plants. Among these,

Biochar‐based fertilizers improve nutrient use efficiency in sunflower grown on a subtropical tidal soil

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Improving fertilizer use efficiency is essential for reducing environmental pollution, sustaining agricultural production, and maximizing the economic profitability of crop production systems. This study tested the hypothesis that the formulation strategy of biochar‐based fertilizers, rather than nutrient addition alone, is associated with ...

First‐in‐human, phase I, randomized, safety, pharmacokinetic, food‐effect and pharmacodynamic study of a tyrosine kinase 2/Janus kinase 1 inhibitor, SDC‐1801

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aim The purpose of this study is to evaluate safety, tolerability, pharmacokinetics (PK), food‐effect (FE) and pharmacodynamics (PD) of an oral tyrosine kinase‐2 (TYK2)/Janus kinase‐1 (JAK1) inhibitor, SDC‐1801, in healthy adult participants. Methods This first‐in‐human study randomized 95 male and female participants.
