Sporulation environment drives phenotypic variation in the pathogen Aspergillus fumigatus.

Aspergillus fumigatus causes more than 300,000 life-threatening infections annually and is widespread across varied environments with a single colony producing thousands of conidia, genetically identical dormant spores. Conidia are easily wind-dispersed to new environments where they can germinate and, if inhaled by susceptible hosts, cause disease. Using high-throughput single-cell analysis via flow cytometry we analyzed conidia produced and germinated in nine environmentally and medically relevant conditions (complete medium, minimal medium, high temperature, excess copper, excess iron, limited iron, excess salt, excess reactive oxygen species, and limited zinc).

Vaccine-Induced Protection in Two Murine Models of Invasive Pulmonary Aspergillosis.

Life-threatening, invasive fungal infections (IFIs) cause over 1.5 million deaths worldwide and are a major public health concern with high mortality rates even with medical treatment. Infections with the opportunistic fungal pathogen, are among the most common.

Management of SARS-CoV-2 pneumonia.

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection has rapidly spread throughout the world since December 2019 to become a global public health emergency for the elevated deaths and hospitalizations in Intensive Care Units. The severity spectrum of SARS-CoV-2 pneumonia ranges from mild to severe clinical conditions. The clinical course of SARS-CoV-2 disease is correlated with multiple factors including host characteristics (genetics, immune status, age, and general health), viral load and, above all, the host distribution of the airways and lungs of the viral receptor cells.

COVID-19 and coagulative axis: review of emerging aspects in a novel disease.

Latest evidences from literature suggest that SARS-CoV-2 disease 2019 (COVID-19) is commonly complicated with coagulopathy and that disseminated intravascular coagulation is present in the majority of deceased patients. Particularly, conventional coagulation parameters appear to be significantly altered in patients with poor prognosis. A wide-ranging cross- talk between coagulative haemostasis and inflammation, as well as the activation of coagulation cascade during viral infections, are well established.

African Americans' knowledge of and attitudes toward coronary artery bypass surgery as a treatment option.

The objective of this study was to determine if African Americans possess knowledge of cardiac bypass surgery as a treatment option, and their willingness to undergo the procedure if it were recommended by a cardiologist. Primary data were collected over a 2-week period. The study setting was a primary care clinic located in an urban area.
