Hypothetical axions provide a compelling explanation for dark matter and could be emitted from the hot solar interior. The CERN Axion Solar Telescope has been searching for solar axions via their back conversion to x-ray photons in a 9-T 10-m long magnet directed toward the Sun. We report on an extended run with the International Axion Observatory pathfinder detector, doubling the previous exposure time.

The objective of the present contribution was to design and characterize resveratrol (RSV) and tocopherol (TOC) loaded quinoa protein (QP) nanocomplexes, their antioxidant and antiradical functionality were also evaluated. QP intrinsic fluorescence spectra showed a quenching effect exerted by RSV and TOC, demonstrating protein-bioactive compounds interactions. Stern-Volmer and Scatchard models application confirmed the static quenching effect and allowed to obtain parameters that described the QP-RSV or QP-TOC complexation process.

Article Synopsis
  • Hip osteoarthritis (HOA) is a common joint disease, and recent research is exploring bone-marrow derived stem cell (BM-MSC) therapy as a possible treatment option.
  • A scoping review was conducted to examine the preparation, dosage, and effectiveness of BM-MSC therapy in treating HOA, using guidelines and a comprehensive literature search.
  • The review found that while BM-MSC therapy seems beneficial in reducing pain and improving function in HOA patients, the studies utilized "low-dose" injections, making it difficult to establish a clear relationship between dose and clinical outcomes.

Objective: Our objective was to assess trends in three sexually transmitted infections (STIs) - gonorrhoea, chlamydia and syphilis - in Spain, by age group and sex from 2016 to 2022.

Study Design: Retrospective observational study.

Methods: Data from epidemiological surveillance system were used to calculate the incidence rate for each STIs by age group and sex.

Nanocomplexes, which possess immense potential to function as nanovehicles, can link diverse ligand compounds. The objective of the present study was to design and characterize resveratrol (RSV)- and tocopherol (TOC)-loaded 11S quinoa seed protein nanocomplexes. Firstly, molecular docking was performed to describe the probable binding sites between protein and ligands, and binding energies of -5.
