Biogenic Ag < sub > 2 < /sub > O nanoparticles with "Hoja Santa" (Piper auritum) extract: characterization and biological capabilities
Biometals. 2024 Feb 26. doi: 10.1007/s10534-024-00589-y. Online ahead of print.ABSTRACTThe 'sacred leaf' or "Hoja Santa" (Piper auritum Kunth) has a great value for Mexican culture and has gained popularity worldwide for its excellent properties from culinary to remedies. To contribute to its heritage, in this project we proposed the green synthesis of silver oxide nanoparticles (Ag2O NPs) using an extract of "Hoja Santa" (Piper auritum) as a reducing and stabilizing agent. The synthesized Ag2O NPs were characterized by UV-Visible spectroscopy (plasmon located at 405 nm), X-ray diffraction (XRD) (particle size diameter of ...

Exploring the chemical and pharmacological variability of Lepidium meyenii: a comprehensive review of the effects of maca
Maca (Lepidium meyenii), a biennial herbaceous plant indigenous to the Andes Mountains, has a rich history of traditional use for its purported health benefits. Maca’s chemical composition varies due to ecotypes, growth conditions, and post-harvest processing, contributing to its intricate phytochemical profile, including, macamides, macaenes, and glucosinolates, among other components. This review provides an in-depth revision and analysis of Maca’s diverse bioactive metabolites, focusing on the pharmacological properties registered in pre-clinical and clinical studies. Maca is generally safe, with rare adverse effect...

Prevalence and quality of life of 11 –15-year-old adolescent young carers in France: a school-based study
AbstractOur study aimed to establish the prevalence of adolescent young carers (AYCs) among 11 –15-year-old French adolescents and explore the impacts of caring on these youths through a comprehensive evaluation of their quality of life. A total of 1983 middle school pupils (mean age = 12.89; 56.23% females) completed self-reported questionnaires evaluating their sociodemographic charac teristics, illness/disability in their family, caring activities (MACA-YC18), quality of life (KIDSCREEN-52), perceived health, and academic performance. Descriptive analyses, Chi-square tests of independence, Student’st-tests, and ...

Macamide, a component of maca (Lepidium meyenii Walp) lipophilic extract, enhances myogenic differentiation via AKT/p38 signaling and attenuates dexamethasone-induced muscle atrophy
In this study, maca roots of various colors (yellow, red, or black) were extracted using different polar solvents (PE, HEX, or BuOH) to compare their effects on muscle differentiation. Among them, the red maca lipophilic extract, which showed the most effectiveness, was chosen for further investigation. Our results show that RMLE enhances muscle differentiation by inducing MyoD-E2A heterodimerization through the activation of the AKT/p38 pathway. Additionally, RMLE attenuated dexamethasone-induced muscle atrophy by inhibiting nuclear translocation of FoxO3a and expression of E3-ligase (MAFbx and MURF1) in vitro and in vivo...

Anti-migratory and cytotoxic effect of indole derivative in C6 glioma cells
Toxicol In Vitro. 2024 Feb 1;96:105786. doi: 10.1016/j.tiv.2024.105786. Online ahead of print.ABSTRACTGliomas are among the most common primary malignant brain tumors. Despite advances in cancer treatment, survival is very low, so the discovery of new therapeutic agents is essential. In this context, indole is an important source for the development of new bioactive molecules. A pharmacological screening of ten indole derivatives was carried out to evaluate the cytotoxic capacity against three tumor cell lines. After pharmacological screening, three compounds were selected, based on their high capacity to reduce cell proli...

Motor and process skills of people with parkinson's disease compared to healthy older adults. A cross-sectional study
CONCLUSION: PD leads to a greater deterioration in motor and process skills compared to healthy older adults. As disease stages advance according to the HY scale, performance in motor and process skills deteriorates significantly between moderate and advanced PD stages. According to the AMPS scale, PD patients show no impairment of processing skills up to HY IV, but motor impairment at HY stages II, III and IV.PMID:38223946 | DOI:10.33588/rn.7802.2023231 (Source: Revista de Neurologia)
