Literacy in Lockdown: Learning and Teaching During COVID-19 School Closures.

Across the globe, students have been away from schools and their teachers, but literacy learning has continued. In many countries, students' literacy proficiency is often measured via high-stakes assessment tests. However, such tests do not make visible students' literacy lives away from formal learning settings, so students are positioned as task responders, rather than as agentive readers and writers.

Management of aortic valve bypass surgery.

The 3 leading causes of aortic stenosis (AS) in adults are calcific degeneration of a normal trileaflet aortic valve (AV), calcific degeneration of a congenital bicuspid AV, and rheumatic AS. Therapeutic options in patients with severe AS include aortic valve replacement (AVR), transcatheter aortic valve implantation (TAVI), or aortic valve bypass (AVB). An AVB involves the placement of a valved conduit between the apex of the left ventricle and the descending thoracic aorta.

My hearing disability is no barrier to work.

I applaud the recent correspondence urging deaf students not to give up their studies (letters September 13). There are many hard of hearing and deaf nurses, doctors, physiotherapists, radiologists and audiologists in the NHS. I am profoundly deaf and work on an acute medical/respiratory ward.

Dynamic and differential changes in myocardial and plasma endothelin in patients undergoing cardiopulmonary bypass.

Objective: The bioactive peptide endothelin modulates left ventricular function by changing afterload, coronary vascular tone, and myocardial contractility. However, whether increased plasma endothelin levels observed in patients during and after coronary revascularization and cardiopulmonary bypass reflect actual myocardial interstitial levels are unknown.

Methods: A microdialysis probe (outer diameter: 0.

A prospective, randomized study of endothelin and postoperative recovery in off-pump versus conventional coronary artery bypass surgery.

Objective: The objectives are 2-fold: (1). to serially determine endothelin (ET) levels in arterial vascular compartments in patients undergoing coronary artery bypass surgery using either cardiopulmonary bypass or off-pump techniques, and (2). to define potential relationships between endothelial levels and specific perioperative parameters of patient recovery.

The Antimicrobial Activity of Phenolic Compounds Against Listeria monocytogenes and Their Effectiveness in a Model Milk System.

The minimum inhibitory concentration (MIC) of several phenolic compounds against eight strains of Listeria monocytogenes in tryptose phosphate agar (TPA) was determined. Based upon concentration, the most effective compound was the phenolic antioxidant tertiary butylhydroquinone (TBHQ) which had a MIC of 64 μg/ml. Among the FDA approved food antimicrobials, the most effective was propyl paraben with a MIC of 512 μg/ml.
