Nutritional status is associated with cognition and grip strength among older adults: A 10-y longitudinal study in Ghana and South Africa

Objectives The current study examined the association between nutritional status and changes in cognition and grip strength among older Ghanaian and South African adults over time using three waves of data from the WHO Study on global AGEing and adult health (SAGE). Methods In total, 6113 and 3623 records of adults aged 60+ y were assessed from Ghanaian and South African datasets, respectively. These were extracted from three waves of the SAGE, conducted between 2007 and 2019. The six-item Mi...

Electron-phonon coupling and mobility modeling in organic semiconductors: Method and application to two tetracene polymorphs

We have developed a first-principles method to calculate the electron-phonon coupling for specific modes and q points in the Brillouin zone for crystalline organic semiconductors. Using the obtained coupling strengths, we propose an approach to compute the temperature-dependent mobilities of electrons and holes. To validate our treatment of the electronic structures and vibrational properties, we calculate the Raman spectra in the lattice-phonon region and compare them with experimental data....

Promoting the remediation of contaminated soils using biochar in combination with bioaugmentation and phytoremediation techniques

Pollutants in soils are detrimental to ecosystems and agricultural production and may also be a pressing threat to human health. In this context, biochar could be used as part of nature-based solutions to remediate polluted areas. In this work, a series of innovative biochar-based strategies were tested in a soil contaminated by hydrocarbons C > 12 and copper (Cu) to investigate their effectiveness in soil decontamination and revegetation potential. Specifically, biochar was applied to soi...

Eco-Physiological and Productive Response of Deficit Irrigated Potatoes

A comprehensive study on both the eco-physiological and productive response of potatoes to dynamic deficit irrigation is lacking. Therefore, the aim was to study, over two growing seasons and on two potato cultivars—Arinda and Timate, the effects of five irrigation regimes (I0–dry control, I1—irrigated control, I2—supply 100% of the maximum evapotranspiration—ETm from tuber initiation up to 50% of tuber growth and 0% ETm from 50% to the end of tuber growth, I3—supply 100% of ETm from tuber in...

Nanoplastics drive toxicity under co-exposure with perfluorooctanesulfonic acid in human intestinal cells

Per- and polyfluoroalkyl substances and nanoplastics frequently co-occur in environmental matrices, yet the effects of co-exposure on cellular responses upon ingestion are poorly understood. Here, we exposed human intestinal Caco-2 cells to perfluorooctanesulfonic acid, nanoplastics, and their combination. Cell painting-based phenomics was used to map phenotypic alterations across subcellular structures, and untargeted metabolomics using ultra-high-performance liquid chromatography coupl...
