Resistance training protects the hippocampus and precuneus against atrophy and benefits white matter integrity in older adults with mild cognitive impairment.

Mild cognitive impairment (MCI) refers to cognitive alterations with preservation of functionality. Individuals with this diagnosis have a higher risk of developing dementia. Non-pharmacological interventions, such as physical exercise, are beneficial for the cognition of this population.

Unlocking the epigenetic code: new insights into triple-negative breast cancer.

Triple-negative breast cancer (TNBC) is a highly aggressive and clinically challenging subtype of breast cancer, lacking the expression of estrogen receptor (ER), progesterone receptor (PR), and HER2/neu. The absence of these receptors limits therapeutic options necessitating the exploration of novel treatment strategies. Epigenetic modifications, which include DNA methylation, histone modifications, and microRNA (miRNA) regulation, play a pivotal role in TNBC pathogenesis and represent promising therapeutic targets.

Biodiversity and Antifungal Activities of Amazonian Actinomycetes Isolated from Rhizospheres of Plants.

Background: Actinobacteria are major producers of antibacterial and antifungal metabolites and are growing their search for substances of biotechnological interest, especially for use in agriculture, among other applications. The Amazon is potentially rich in actinobacteria; however, almost no research studies exist. Thus, we present a study of the occurrence and antifungal potential of actinobacteria from the rhizosphere of , a native South American plant and one that is economically useful in the whole of the Amazon.

Biosurfactant Production using URM 1150 and its Application in the Bioremediation of Coast Environments Impacted by Oil Spills.

Background: This study aimed to produce, characterize, and apply a biosurfactant as a bioremediation tool for oil-contaminated coastal environments.

Methods: The biosurfactant was produced in a medium containing 5.0% corn steep liquor and 1.

Total coliforms, E. coli, Enterococcus spp., and Staphylococcus spp. removal in vertical tubular photobioreactor with and without support medium.

Unsafe water has severe implications for human health. Among sanitary wastewater treatment technologies, those that treat effluent in the most natural way possible (avoiding chemicals) need to be employed to minimize environmental damage upon release. Microalgae-based systems are one of the more economical and sustainable methods.
