Unveiling the potential of a whey protein- and leucine-enriched multi-nutrient formula high in vitamin D3: A scoping review on its role in enhancing body composition, strength, and... by Daniel A. Traylor, Everson A. Nunes, Matthew Lees, Mitchell J. Plucinski, Megan Vondrasek, Stuart M. Phillips

“…The present study undertakes a scoping review of research on whey protein- and leucine-enriched multi-nutrient formulas high in vitamin D3 in older adults with sarcopenia to highlight the impact of feeding and feeding with exercise on body composition, strength, and physical function. Design: Online databases identified studies published from 2005-2023, for which we selected 11 English-language studies that experimented with a whey protein—and leucine-enriched multi-nutrient formula(e) high in vitamin D3 on measures of sarcopenia as the primary outcome variables in older adults diagnosed as sarcopenic. …”

Optimization of variables for cadmium and copper removal using magnetic nanocomposite by Chou-Yi Hsu, Mohammed Ahmed Mustafa, Ghadir Kamil Ghadir, Pooja Bansal, Harpreet Kaur, Amjed Qasim Mohammed, Alzahraa S. Abdulwahid, Ahmed Remthan Hussein, Sahira Qasim Namaha, Ahmed Ali Ami, Usama Kadem Radi, Laith H. Alzubaidi, Ali Kazemi

“…Abstract This study aims to investigate cadmium and copper ultrasound-assisted removal efficiency on a laboratory scale using a cobalt ferrite/activated carbon (COF/AC) composite as an adsorbent. For this purpose, the effect of four independent variables (i.e., composite amount, pH, heavy metal concentrations, and ultrasound radiation time) on the performance of the cadmium and copper removal was investigated. …”

Association of climate variability modes with concurrent droughts and heatwaves in India by Ruhhee Tabbussum, Rajarshi Das Bhowmik, Pradeep Mujumdar

“…This study explores this association by demonstrating how concurrent droughts and heatwaves (CDHW) in India are temporally and spatially connected to multiple global teleconnections (referred to as climate variability modes). Composite and wavelet coherence analyses are implemented for the univariate evaluation of droughts and heatwaves—measured using the standardized precipitation index (SPI) and the standardized heat index (SHI), respectively—in relation to the climate variability modes. …”
