Changes in chemical composition and biological activity of essential oil from Thomson navel orange ( L. Osbeck) peel under freezing, convective, vacuum, and microwave drying methods.

Thomson navel orange peel is a by-product of citrus processing, which contains high levels of bioactive compounds advantageous to human health, nevertheless due to its high moisture content it is exceedingly perishable. Drying is among the most common preservation methods, which could prolong the plants shelf-life via reducing their moisture value. Taking this into account, depending on their type and conditions, drying techniques could degrade plant heat-sensitive metabolites and lead to quality decline.

Midterm Follow-up Results of Transcatheter Interatrial Septal Defect Closure.

Objectives: We studied immediate and midterm results of transcatheter closure of atrial septal defects (ASDs) using the Amplatzer septal device closure.

Methods: The study included one hundred and thirty-seven patients (31 men, 106 women; mean age 8 ± 7.3 years; range 1-65 years) who underwent transcatheter closure of secundum ASD between October 2014 and October 2016 in our center.
