Discovery of CO tolerance genes associated with virulence in the fungal pathogen Cryptococcus neoformans.

Cryptococcus neoformans is a ubiquitous soil fungus and airborne pathogen that causes over 180,000 deaths each year. Cryptococcus must adapt to host CO levels to cause disease, but the genetic basis for this adaptation is unknown. We utilized quantitative trait loci mapping with 374 progeny from a cross between a CO-tolerant clinical isolate and a CO-sensitive environmental isolate to identify genetic regions regulating CO tolerance.

Escaping the benthos with Coral Reef Arks: effects on coral translocation and fish biomass.

Anthropogenic stressors like overfishing, land based runoff, and increasing temperatures cause the degradation of coral reefs, leading to the loss of corals and other calcifiers, increases in competitive fleshy algae, and increases in microbial pathogen abundance and hypoxia. To test the hypothesis that corals would be healthier by moving them off the benthos, a common garden experiment was conducted in which corals were translocated to midwater geodesic spheres (hereafter called Coral Reef Arks or Arks). Coral fragments translocated to the Arks survived significantly longer than equivalent coral fragments translocated to Control sites (.

Impact of C-reactive Protein on Anticoagulation Monitoring in Extracorporeal Membrane Oxygenation.

Objective: To evaluate the impact of inflammation on anticoagulation monitoring for patients supported with extracorporeal membrane oxygenation (ECMO).

Design: Prospective single-center cohort study.

Setting: University-affiliated tertiary care academic medical center.

Effects of CO in fungi.

Carbon dioxide supplies carbon for photosynthetic species and is a major product of respiration for all life forms. Inside the human body where CO is a by-product of the tricarboxylic acid cycle, its level reaches 5% or higher. In the ambient atmosphere, ∼.

Aspartyl peptidase May1 induces host inflammatory response by altering cell wall composition in the fungal pathogen .

Unlabelled: causes cryptococcal meningoencephalitis, a disease that kills more than 180,000 people annually. Contributing to its success as a fungal pathogen is its cell wall surrounded by a capsule. When the cryptococcal cell wall is compromised, exposed pathogen-associated molecular pattern molecules (PAMPs) could trigger host recognition and initiate attack against this fungus.
