After drying, the L. lactis that had adapted to acid or osmotic stresses did not differ statistically in terms of cell viability loss compared to the control samples tested (~0.38 log cycles). However, the cells that had adapted to oxidative conditions demonstrated a cell viability loss of only 0.01 log cycles. After 45 d of storage at temperatures of 4 and 25 °C, the final L. lactis sample populations were shown to be higher (112.5%) when they had been submitted to sublethal conditions of oxidative stress. When the cell samples were exposed to acid stress conditions, they exhibited a viability loss (0.82 log cycles) that was statistically different from the control sample (0.58 log cycles) after 45 d. Osmotic stress conditions did not demonstrate any influence over cell survival rates. Thus, submitting cells to oxidative stress conditions prior to storage has been shown to be a potential strategy for producing dehydrated cultures of L. lactis strains that are less sensitive to oxygen exposure.Iron overload is associated with an increased risk of atrial and ventricular arrhythmias. Data regarding the relationship between electrocardiographic parameters of atrial depolarisation and ventricular repolarisation with cardiac T2* MRI are scarce. Therefore, we aimed to investigate these electrocardiographic parameters and their relationship with cardiac T2* value in patients with β-thalassemia major. In this prospective study, 52 patients with β-thalassemia major and 52 age- and gender-matched healthy patients were included. Electrocardiographic measurements of QT, T peak to end interval, and P wave intervals were performed by one cardiologist who was blind to patients' data. All patients underw
