A Small-Particle Aerosol Model of Ebolavirus Zaire Infection in Ferrets.
Viruses
November 2024
Viral Immunology Branch, Virology Division, U.S. Army Medical Research Institute of Infectious Diseases, Frederick, MD 21702, USA.
The Ebola virus (EBOV) causes severe disease in humans, and animal models are needed to evaluate the efficacy of vaccines and therapeutics. While non-human primate (NHP) and rodent EBOV infection models have been well characterized, there is a growing need for an intermediate model. Here, we provide the first report of a small-particle aerosol (AE) EBOV ferret model and disease progression compared with the intramuscular (IM) EBOV ferret model.

Background/objectives: Amyloid peptides, whose accumulation in the brain as senile plaques is associated with the onset of Alzheimer's disease, are also found in cerebral vessels and in circulation. In the bloodstream, amyloid peptides promote platelet adhesion, activation, oxidative stress, and thrombosis, contributing to the cardiovascular complications observed in Alzheimer's disease patients. Natural compounds, such as curcumin, are known to modulate platelet activation induced by the hemostatic stimuli thrombin and convulxin.

Dysregulated cellular metabolism is known to be associated with drug resistance in cancer treatment. In this study, we investigated the impact of cellular adaptation to lactic acidosis on intracellular energy metabolism and sensitivity to docetaxel in prostate carcinoma (PC) cells. The effects of curcumin and the role of hexokinase 2 (HK2) in this process were also examined.

Department of Environmental Engineering, University of Warmia and Mazury in Olsztyn, Warszawska St. 117a, 10-957 Olsztyn, Poland.
This study aimed to investigate the effect of aminating waste newsprint paper with different aminating agents (ammonia/ammonia water, ethylenediamine, and diethylenetriamine) for the sorption efficiency of Reactive Black 5 (RB5) and Reactive Yellow 84 (RY84) dyes. To increase the amination efficiency, the paper material was pre-activated with epichlorohydrin. The scope of this study included the characterization of the sorbents tested (FTIR, elemental analysis, BET surface area, porosity, and pH), determination of the influence of pH on dye sorption efficiency, sorption kinetics, and the maximum sorption capacity of the dyes.

By combining molecular dynamics (MD) simulations and density functional theory (DFT), the influence of dye structure on the optical modulation properties of negative-mode guest-host liquid crystal (GHLC) systems was systematically investigated. Firstly, the reliability of the simulation method was validated by comparing the performance parameters of the GHLC system obtained from simulations with those from experimental results. Subsequently, a series of guest dye molecules, along with their mixtures with negative dielectric anisotropy mesogens, were designed and analyzed.
