PURPOSE We report updated outcomes of single- versus multifraction stereotactic body radiation therapy (SBRT) for unresectable pancreatic adenocarcinoma. METHODS AND MATERIALS We included 167 patients with unresectable pancreatic adenocarcinoma treated at our institution from 2002 to 2013, with 1-fraction (45.5% of patient) or 5-fraction (54.5% of patients) SBRT. The majority of patients (87....
The profile of the survival curves, at different heating temperatures, of B. coagulans STCC 4522 sporulated at 52(deg)C has been studied, focusing on the early moments of treatment. A highly heat-sensitive spore subpopulation that includes more than 90% of the total spore population has been found. This heat-sensitive spore fraction was inactivated after 2 s of treatment at 111(deg)C. Its heat ...
OBJECTIVE To assess the effect of the oscillatory breathing on the variability of RR intervals (VRR) and on prognostic significance after one year follow-up in subjects with left ventricular global systolic dysfunction. METHODS We studied 76 subjects, whose age ranged from 40 to 80 years, paired for age and gender, divided into two groups: group I - 34 healthy subjects; group II - 42 subjects...
BACKGROUND Dilated cardiomyopathy is an important cause of morbidity and mortality among patients with congestive heart failure. Hemodynamic and prognostic characterization are critical in guiding selection of medical and surgical therapies. METHODS AND RESULTS A cohort of 102 patients with the clinical diagnosis of dilated cardiomyopathy who underwent echocardiographic examination between 19...
Introduction Due to the neurocognitive side effects of whole brain radiation therapy (WBRT), stereotactic radiosurgery (SRS) is being used with increasing frequency. The use of SRS is expanding for patients with multiple (>4) brain metastases (BM). This study summarizes our institutional experience with single-fraction, linear-accelerator-based SRS for multiple BM. Methods and materials All p...
Previous in vivo studies have shown that beta-alanine is incorporated specifically into the dipeptide L-carnosine (beta-alanyl-L-histidine). In the present study, we administered beta-[3H]alanine to the nasal cavity of hamsters and used biochemical analyses to identify the radioactively labeled compounds in the olfactory epithelium and olfactory bulb and autoradiography to demonstrate the local...
