All patients were screened with transesophageal echocardiography before the operation. All patients underwent intracardiac echocardiography study and attempted closure.\n\nResults Ten patients (7.1%) underwent an attempt at transcatheter closure in the presence of hypertrophy of the rims (eight patients)
or lipomatosis (two patients). All patients were aged more than 50 years and has multiple recurrent stroke events (nine patients) or need for a posterior cerebral surgical procedure (one patient) making closure mandatory. After intracardiac echocardiography study and measurements, two 25 mm Amplatzer and eight 25 mm Premere Occlusion System devices have been implanted successfully. On mean follow-up of 36.6 +/- 14.8 months, two patients had a small residual shunt: no recurrence of stroke or aortic erosion or device thrombosis was observed ALK inhibitor during this ATM/ATR inhibitor clinical trial period.\n\nConclusion Transcatheter PFO closure in the presence of hypertrophy or lipomatosis of fossa ovalis rims is not contraindicated per se: careful evaluation of rim thickness with intracardiac echocardiography and selection of soft and asymmetrically opening devices may allow for a safe and effective PFO closure, at least in patients with no severe atrial septal aneurysm.

tissue fixation and processing is as old as 100 years and find more still remains the gold standard against which all new technologies and methods need to be assessed. Tissue processing is one of the important steps for obtaining good thin sections without artifacts. Though conventional tissue-processing methods are most commonly followed, they are well-known as very laborious and tedious procedures. Microwaves a form of electromagnetic wave-induced heat, when applied in histotechnology, reproducibly yields histolologic material of similar or superior quality to that provided by conventional processing methods, making it more popular in the recent years. A laboratory microwave offers features like
maximum output of 2000-3000 watts, an in-built source of adjustable temperature probe, facility for ventilation of hazardous fumes, but is expensive. Considering the usefulness of microwave in histotechnology, i.e., reducing the time required for the diagnosis, replacing the conventional equipments of laboratories by microwave-guided ones is a remarkable and an acceptable change.”
“Saimiri sciureus is one of the smallest Cebidae native of Amazon region and also found at the biological reserve of northeast Atlantic forest. It is an omnivore animal, with diversified diet that directly influences the lingual mucosa, which includes certain types of papillae with different organization levels. The present study attempted to describe the morphological and ultrastructure aspects of the dorsal surface of the S. sciureus. Five tongues of de S.
