The study found that participants who received ART immediately had better outcomes and were protected from disease progression not only during treatment but also after treatment was stopped.
A new study found that adding inhaled dry powder mannitol to standard therapy for cystic fibrosis improved lung function over 52 weeks. The treatment showed a significant improvement in forced expiratory volume in one second (FEV1) and fewer pulmonary exacerbations compared to the control group.
Researchers at the University of Bristol used musical features and machine learning algorithms to predict song hits in the UK singles chart. They found that danceability increased in popularity from the late 1970s and that slower styles, such as ballads, were more likely to become hits in the 1980s.
A comprehensive study found that maternal use of inhaled glucocorticoids for asthma during pregnancy is not associated with most diseases in childhood, but may increase the risk of endocrine and metabolic disorders. The study followed 65,085 mother-child pairs from early pregnancy to childhood.
Two Ontario research facilities, The Centre for Applied Genomics and StemCore Laboratories, have been awarded $10,000 each to develop leading-edge technologies in Next Generation Sequencing (NGS) methods.
