High accuracy of genome-enabled prediction of belowground and physiological traits in barley seedlings.

In plants, the study of belowground traits is gaining momentum due to their importance on yield formation and the uptake of water and nutrients. In several cereal crops, seminal root number and seminal root angle are proxy traits of the root system architecture at the mature stages, which in turn contributes to modulating the uptake of water and nutrients. Along with seminal root number and seminal root angle, experimental evidence indicates that the transpiration rate response to evaporative demand or vapor pressure deficit is a key physiological trait that might be targeted to cope with drought tolerance as the reduction of the water flux to leaves for limiting transpiration rate at high levels of vapor pressure deficit allows to better manage soil moisture.

Management of a complicated redo giant dissecting aortic aneurysm.

Giant aortic aneurysm is defined as an aneurysm of the aorta of greater than 10 cm in diameter. This rare condition is associated with a high risk of morbidity and mortality and it may lead to fatal complications such as rupture and/or dissection if not managed with proper surgical planning and expertise. Other than atherosclerosis, the main causes of giant ascending aortic aneurysms include Marfan and Ehlers-Danhlos syndromes.
