Water Uptake of Airborne Cells of Measured with a Hygroscopicity Tandem Differential Mobility Analyzer.
Environ Sci Technol
October 2024
Department of Chemistry, Aarhus University, Aarhus 8000, Denmark.
Article Synopsis
- Airborne microorganisms can influence cloud formation and disease spread, and their ability to survive is affected by water availability in the atmosphere.
- Researchers studied the hygroscopic properties (water-attracting ability) of a plant pathogen that aids in cloud formation using a specialized analyzer.
- The study found that while pure cells absorbed little water and had a growth factor of 1.09 at high humidity, cells mixed with salt showed significantly greater hydration, with a growth factor of 1.74, indicating the crucial role of salt in water uptake.
Analyzing Global Cancer Control: Progress of National Cancer Control Programs through Composite Indicators and Regression Modeling.
J Med Phys
June 2024
Centre for Cosmology, Astrophysics and Space Science, GLA University, Mathura, Uttar Pradesh, India.
Aim: Cancer is a significant public health concern, and National Cancer Control Programs (NCCPs) are crucial for reducing its burden. However, assessing the progress of NCCPs is challenging due to the complexity of cancer control outcomes and the various factors that influence them. Composite indicators can provide a comprehensive and accurate assessment of NCCP progress.

Comput Biol Med
September 2024
Center for Mechanical Technology & Automation (TEMA), Department of Mechanical Engineering, University of Aveiro, Aveiro, Portugal; Intelligent Systems Associate Laboratory (LASI), Guimarães, Portugal.
Problem: Therapeutic planning strategies have been developed to enhance the effectiveness of cancer drugs. Nevertheless, their performance is highly limited by the inefficient biological representativeness of predictive tumor growth models, which hinders their translation to clinical practice.
Objective: This study proposes a disruptive approach to oncology based on nature-inspired control using realistic Black Hole physical laws, in which tumor masses are trapped to experience attraction dynamics on their path to complete remission or to become a chronic disease.
Phenotyping COVID-19 respiratory failure in spontaneously breathing patients with AI on lung CT-scan.
Crit Care
August 2024
Department of Anesthesiology, Critical Care, and Pain Medicine, Massachusetts General Hospital, Harvard Medical School, Boston, USA.
Article Synopsis
- Automated analysis of lung CT scans can help classify different subphenotypes of acute respiratory illness in COVID-19 patients by combining CT features with clinical and lab data.
- A study of 559 spontaneously breathing COVID-19 patients identified two subphenotypes: one with older patients, higher inflammation, more severe hypoxemia, and a higher mortality rate, while the other had distinct lung imaging features and lower mortality.
- The findings emphasize the potential of using machine learning and lung-CT imaging to improve the understanding and treatment of respiratory failure in COVID-19 patients.
Effects of temperature, chloride and perchlorate salt concentration on the metabolic activity of Deinococcus radiodurans.
Extremophiles
July 2024
Center for ExoLife Sciences, (CELS), Niels Bohr Institute, University of Copenhagen, Øster Voldgade 5-7, 1350, Copenhagen, Denmark.
The extremophile bacterium Deinococcus radiodurans is characterized by its ability to survive and sustain its activity at high levels of radiation and is considered an organism that might survive in extraterrestrial environments. In the present work, we studied the combined effects of temperature and chlorine-containing salts, with focus on perchlorate salts which have been detected at high concentrations in Martian regolith, on D. radiodurans activity (CO production rates) and viability after incubation in liquid cultures for up to 30 days.
