OBJECTIVE Studies have suggested that insulin resistance plays a role in cognitive impairment in individuals with type 2 diabetes. We aimed to determine whether an improvement in insulin resistance could explain cognitive performance variations over 36 weeks in older individuals with mild cognitive impairment (MCI) and type 2 diabetes.

AIMS We designed this study in order to determine the effect of insulin on cardiac function in overweight and obese subjects during exercise. METHODS AND RESULTS The cardiac function of 62 normal glucose tolerant subjects, aged 30-40 and divided into normal weight (group 1, n=22, BMI 20-24.9 kg/m(2)), overweight (group 2, n=20, BMI 25-29.9 kg/m(2)), and(More)
BACKGROUND To quantitatively evaluate radiation-induced impaired oesophageal transit with oesophageal transit scintigraphy and to assess the relationships between acute oesophagitis symptoms and dysmotility. METHODS Between January 1996 and November 1998, 11 patients affected by non-small-cell carcinoma of the lung not directly involving the oesophagus,(More)
Adenocarcinoma arising from a mediastinal cyst was detected by exercise technetium-99m hexakis-2-methoxyisobuty-lisonitrile (99m)Tc-MIBI scintigraphy in a 65-year-old woman with known coronary disease. This guided further investigations and resection of the tumor which stained positive for P-glycoprotein. Three years earlier, myocardial scintigraphy was(More)
OBJECTIVE To evaluate the usefulness of (99m)Tc-2-Methoxy-Isobutyl-Isonitrile Single Photon Emission Computed Tomography (MIBI-SPECT) for assessing anterior mediastinal mass, and distinguishing the grade of malignancy of thymic epithelial tumors to offer guidance for decision making. METHODS From January 2006 to November 2009, 31 consecutive patients with(More)
Selective deep lobe parotidectomy is a demanding technique, but it preserves healthy glandular tissue, improves cosmetic results and minimises the incidence of Frey's syndrome. We have evaluated postoperative function of the superficial lobe of the parotid after selective resection of the deep lobe. Fourteen patients who each had a mass involving the deep(More)
After esophagectomy, the stomach is usually used to restore digestive continuity. To prevent postoperative delayed gastric emptying, most authors perform a gastric drainage procedure or transpose a tubulized stomach. The aim of our work is to evaluate the emptying of a transposed whole stomach without performing a pyloromyotomy or a pyloroplasty. From 1996(More)
We propose a new method based on the differential absorption lidar technique for multipollutant detection. A broadband laser is sent into the atmosphere in a wavelength range in which several pollutants absorb. The backscattered light is analyzed by a Fourier-transform spectrometer with time resolution. This mode of detection provides both spatial and high(More)
BACKGROUND To demonstrate the diagnostic accuracy of an integrated approach of blind trans-bronchial needle aspiration (TBNA) and (99m)Tc-2-methoxy-isobutyl-isonitrile single photon emission computed tomography ((99m)Tc-MIBI-SPECT) in diagnosing mediastinal lymph adenopathy. METHODS Sixty one consecutive patients with mediastinal lymph adenopathy(More)
