Progress in psychiatric treatment has led to important improvements in the quality of life of patients with severe mental illness (SMI). Nevertheless, the life expectancy of patients with SMI remains two decades shorter than that of the general population, and the most prevalent cause of death is cardiovascular disease. Given that the delivery of somatic care to a population of individuals with mental illness is specific, we developed a screening and intervention programme aimed at this vulnerable population.

Comparative Study of Water and Milk Kefir Grains as Biopolymeric Adsorbents for Copper(II) and Arsenic(V) Removal from Aqueous Solutions.

Polymers (Basel)

November 2024

Institute of Laboratory Research on Geomaterials, Faculty of Natural Sciences, Comenius University in Bratislava, Mlynská dolina, Ilkovičova 6, 842 15 Bratislava, Slovakia.

This study investigates the biosorption capabilities of kefir grains, a polysaccharide-based byproduct of the fermentation process, for removing copper(II) and arsenic(V) from contaminated water. Unlike traditional heavy-metal removal methods, which are typically expensive and involve environmentally harmful chemicals, biopolymeric materials such as kefir grains provide a sustainable and cost-effective alternative for adsorbing hazardous inorganic pollutants from aqueous solutions. Our experimental results revealed significant differences in the sorption capacities of two types of kefir grains.

Spaced Hybrid TiO/Au Nanotube Arrays with Tailored Optical Properties for Surface-Enhanced Raman Scattering.

ACS Omega

December 2024

Czech Advanced Technology and Research Institute (CATRIN), Regional Centre of Advanced Technologies and Materials Department, Palacký University Olomouc, Šlechtitelů 27, Olomouc 78371, Czech Republic.

Controlling the overall geometry of plasmonic materials allows for tailoring their optical response and the effects that can be exploited to enhance the performance of a wide range of devices. This study demonstrates a simple method to control the size and distribution of gold (Au) nanoparticles grown on the surface of spaced titanium dioxide (TiO) nanotubes by varying the deposition time of magnetron sputtering. While shorter depositions led to small and well-separated Au nanoparticles, longer depositions promoted the formation of quasi-continuous layers with small interparticle gaps.

Phys Rev Lett

November 2024

Fermi National Accelerator Laboratory, Batavia, Illinois 60510, USA.

This Letter reports a search for charge-parity (CP) symmetry violating nonstandard interactions (NSI) of neutrinos with matter using the NOvA Experiment, and examines their effects on the determination of the standard oscillation parameters. Data from ν_{μ}(ν[over ¯]_{μ})→ν_{μ}(ν[over ¯]_{μ}) and ν_{μ}(ν[over ¯]_{μ})→ν_{e}(ν[over ¯]_{e}) oscillation channels are used to measure the effect of the NSI parameters ϵ_{eμ} and ϵ_{eτ}. With 90% CL the magnitudes of the NSI couplings are constrained to be |ϵ_{eμ}|≲0.

Article Synopsis
  • - The study investigates the effectiveness of a new ECG technique called CineECG, which visualizes heart electrical activity, in improving cardiac resynchronization therapy (CRT) for patients who don't respond well to standard treatments.
  • - Researchers analyzed CineECG data from 15 patients with heart conditions under different pacing settings and found that specific movement directions in the heart's electrical signals correlate with better immediate heart performance (measured as dP/dt max).
  • - The results indicate that the direction of the ST-T segment during repolarization can predict a significant improvement in heart function during CRT, suggesting that CineECG could help optimize treatment plans for patients.
