Twelve-week-old male rats of reproductive age ( = 24) were randomly divided into three groups, the (i) control group, (ii) BEP group, and (iii) BEP+ glutathione group.

Culturing, Freezing, Processing, and Imaging of Entire Organoids and Spheroids While Still in a Hydrogel.

Organoids and spheroids, three-dimensional growing structures in cell culture labs, are becoming increasingly recognized as superior models compared to two-dimensional culture models, since they mimic the human body better and have advantages over animal studies. However, these studies commonly face problems with reproducibility and consistency. During the long experimental processes - with transfers of organoids and spheroids between different cell culture vessels, pipetting, and centrifuging - these susceptible and fragile 3D growing structures are often damaged or lost.

Giant pulmonary pseudoaneurysm following balloon dilatation of the pulmonary artery to relieve pulmonary band.

Pulmonary artery pseudoaneurysms are uncommon. They may occur secondary to trauma, infectious diseases, vasculitis syndromes, neoplasms, congenital diseases, and pulmonary hypertension. Due to increasing number of cardiac interventions, iatrogenic complications are among the major causes of pulmonary artery pseudoaneurysms.

Patent ductus arteriosus ligation under high-frequency oscillatory ventilation in two critically ill pre-mature newborns.

Information on the use of high-frequency oscillatory ventilation in neonatal surgeries is very rare. In this report, we discuss two pre-term infants who had to receive high-frequency oscillatory ventilation as a rescue treatment due to severe pre-maturity. These two cases underwent successful bedside patent ductus arteriosus ligation under high-frequency oscillatory ventilation, and this shows us that patent ductus arteriosus ligation can be performed successfully in neonates even under high-frequency oscillatory ventilation.
