A right frontal and left cerebellar diaschisis, resulting from a right pontine infarction, is reported in a patient with complete left hemiplegia. Magnetic resonance imaging and CT scan supported the existence of the pontine infarction. The SPECT-HMPAO-99mTc showed a relative hypoactivity in the right frontal lobe and left cerebellar hemisphere.
The performance characteristics of 5 scintillation cameras were compared: Searle 19, Searle 37, Ohio Nuclear, Picker 2C and Toshiba GCA 202. Inherent characteristics including spatial resolution, field uniformity and distortion, energy resolution, count-rate capability and paralyzing time were measured. Extrinsic characteristics such as spatial resolution(More)
During the last six years, the search for a deficiency in alpha-1-antitrypsin (AAT) was carried out in 106 children aged from 5 months to 14 years, having the obstructive pulmonary syndrome. Nine deficiencies were in this manner detected and phenotyped. These are the observations of three of these children which are reported here. Their age ranged between 4(More)
Metaiodobenzylguanidine (MIBG) is a specific marker for neuroendocrine tumours, such as phaeochromocytoma, neuroblastoma, medullary thyroid cancer (MTC) and paraganglioma, but it suffers in some cases (especially in MTC) from a lack of sensitivity. Thallium is a well-known marker of cellularity with a great sensitivity and a lack of specificity. In order to(More)
OBJECTIVE To assess the value of hepatic flow scintigraphy for occult metastases. DESIGN Prospective study, 2 years of follow-up. SETTING AND STUDY PARTICIPANTS One hundred twenty-nine patients undergoing surgery for gastrointestinal cancer. INTERVENTION Preoperative hepatic flow scintigraphy (3mCi of technetium-99m). MAIN OUTCOME MEASURE(More)
Marine multicellular organisms in composition with their associated microbiota-representing metaorganisms-are confronted with constantly changing environmental conditions. In 2110, the seawater temperature is predicted to be increased by ~5°C, and the atmospheric carbon dioxide partial pressure (pCO2) is expected to reach approximately 1000 ppm. In order to(More)
A soluble form of Streptococcus pneumoniae PBP2x, a molecular target of penicillin and cephalosporin antibiotics, has been expressed and purified. IR difference spectra of PBP2x acylated with benzylpenicillin, cloxacillin, cephalothin and ceftriaxone have been measured. The difference spectra show two main features. The ester carbonyl vibration of the(More)
