Hypoglycemia induced by long-acting somatostatin analogues in a patient with nonfunctional neuroendocrine tumor

Somatostatin and its long-acting analogues are effective in symptom control in patients with functional neuroendocrine tumors; they are also able to control tumor growth. Somatostatin analogues are safe and generally well tolerated. In some cases they may cause serious complications

Effect of overweight and obesity on the left ventricular systolic and diastolic functions in patients with acute myocardial infarction

Purpose: The purpose of this study was to evaluate whether a association exits among overweight and obesity and left ventricular systolic and diastolic functions in patients admitted with first ST-elevation myocardial infarction (STEMI). Methods: The present study was performed on 451 consecutive patients diagnosed with first STEMI (376 men, 75 women; mean age 56.1±10.8 years). The patients were classified into three groups based on their body mass index (BMI) as normal weight (BMI 30 kg/m2). Echocardiographic features were evaluated and compared among the three groups. Results: Mitral annulus E velocities were higher in obese individuals than normal weight group (p 0.05). Conclusion: These results suggest that while obesity has no adverse effect on the left ventricular systolic function, it has unfavorable consequences on the left ventricular diastolic function in the patients with first STEMI. In contrast, no unfavorable effects of overweight on the left ventricular systolic and diastolic function were detected

Electronic Structure of FePc and Interface Properties on Ag 111 and Au 100

The electronic structure of iron phthalocyanine FePc and interface properties on Ag 111 and Au 100 are investigated by photoexcited electron spectroscopies photoemission XPS and UPS and X ray absorption spectroscopy XAS or NEXAFS . Valence band structures with Fe character were identified using resonant photoemission. The strength and nature of the interaction at the interface depend clearly on the substrate. A strong interaction of the central metal atom of the phthalocyanine occurs on Ag 111 , whereas no significant changes of the electronic situation were found for FePc on Au 100 . Resonant photoemission data show that for FePc on Ag 111 the formed interface states close to the Fermi level are determined by the interaction between Fe 3d states and substrate related states. On the other hand, also the nitrogen atom of FePc is involved in the interactio

Reversible P3HT/oxygen charge transfer complex identification in thin films exposed to direct contact with water

Combined systems of semiconducting polymers and aqueous electrolytes are emerging as a new frontier of organic electronics, with many promising applications in neuroscience, biomedicine, and photoelectrochemical cells. A detailed characterization of the effect of direct, prolonged contact with water in working conditions, typically upon visible light illumination, is thus urgently needed. Here, we report a comprehensive study of processes occurring in thin films of regioregular poly(3-hexylthiophene) (rr-P3HT), the election material for such applications, exposed to different environmental conditions. We demonstrate that the contact with saline solutions is not worse than contact with open air: in both situations the reversible formation of a charge transfer complex between polymer and molecular oxygen is the main phenomenon, enhanced by visible light illumination. Experimental data and theoretical modeling provide an insightful picture of the complex formation, as a precursor of photoactivated doping, and first unambiguously identify its spectral signature by means of vibrational spectroscopy techniques. In perspective, this work validates use of semiconducting polymers in contact with electrolytes and paves the way to new, rapidly emerging trends in organic electronics
