Chemical characterization and antioxidant potential of Arthrospira sp., Thalassiosira sp., and Raphidonema sp.

Microalgae are emerging as valuable sources of bioactive compounds. This study evaluates hexane extracts from Thalassiosira sp. and Raphidonema sp.

Association between lactate determined at emergency department arrival and the probability of inhospital mortality and intensive care admission in elderly patients.

Background And Importance: Elderly patients often have atypical clinical presentations. Lactate measurement on arrival at the Emergency Department (ED) could be useful to identify elderly patients with a bad prognosis.

Objective: The study aimed to investigate the relationship between serum lactate determined at ED arrival and the probability of inhospital mortality and intensive care (ICU) admission in elderly patients.

Unlocking the potential of fermented beetroot ketchup: Enhancing polyphenol recovery and gut microbiota interactions.

The study aimed to evaluate the effect of digestion and gut microbiota interactions on beetroot ketchup formulations, focusing on the release of polyphenols, bioaccessibility, and microbial interactions on gut microbiota with polyphenols. Tested ketchup samples were evaluated using the TNO Gastro-Intestinal Model 1 (TIM-1) simulated upper part of the gastrointestinal tract and the TNO Gastro-Intestinal Model 2 (TIM-2) simulated colon system. The results showed that fermentation of ketchup with Lactobacillus johnsonii K4, increased the release of bioactive compounds during digestion, with higher polyphenol recoveries observed in fermented samples.

Effectiveness and safety of the recombinant herpes zoster vaccine in different population groups: a systematic review and meta-analysis.

Varicella-zoster virus infections have increased globally, with complications such as postherpetic neuralgia and neurological sequelae. The recombinant vaccine against herpes zoster is proposed as a preventive strategy. This systematic review evaluates its effectiveness and safety in healthy and high-risk populations.

Exploring the Potential of Invasive Species : Microwave-Assisted Extraction Optimization and Bioactivity Profiling.

(SM) poses a serious environmental issue since it is a fast-expanding invasive species occupying key areas of the European shoreline, disrupting the autochthonous algae species, and disturbing the ecosystem. This problem has concerned the general population and the scientific community. Nevertheless, as macroalgae are recognized as a source of bioactive molecules, the abundance of SM presents an opportunity as a raw material.
