...a species is also clinically associated with human respiratory disorders such as allergy, asthma, and chronic sinusitis. Spores, which are often termed conidia in some fungi, are an essential part of the developmental cycle of A. brassicicola and arise from the branching filaments or hyphae that make up the fun...

New study: Preterm birth causes one-third of all infant deaths

...s of infant death and combined conditions, such as respiratory distress syndrome, which frequently occur in premature babies. This new method doubled the percentage of infant deaths caused by premature birth to 34.3 percent. More than 95 percent of those deaths were of infants who were born at less than 32 wee...

"A normal baby will wake up, turn its head, and start breathing faster when carbon dioxide levels rise," explains Kinney. But in babies who die from SIDS, defects in the ser...

Penn study on lung-infecting bacterial enzyme suggests new approach to cystic fibrosis treatment

To make matters worse, the products of the lipid breakdown are also known to trigger inflammation and cell death. Together, these facts c...

New research shows that flu is a trigger of heart attacks
