The purpose of this study was to investigate the associations between regional cerebral blood flow (rCBF) and cognitive function in patients having a local stroke within the thalamus or putamen. The Mini-Mental State Examination(MMSE)and the Kohs Block Design Test(KBDT) were used to evaluate cognitive function. Brain single-photon emission computed tomography (SPECT)was performed with Tc-ethyl ...

To investigate over time changes in striatal dopamine transporter (DAT), we performed two sequential N-omega-fluoropropyl-2beta-carbomethoxy-3beta-(4-iodophenyl) tropane single photon computed tomography (SPECT) scans in 20 subjects with essential tremor (ET), in 13 with Parkinson disease (PD) and in 23 healthy controls (HC, one scan only). We also performed an [(99m)Tc]ethyl cysteinate dimer b...

Natriuretic peptide receptor (NPR) A is composed of an extracellular domain (ECD) with a ligand binding site, a single transmembrane region, a kinase homology domain, and a guanylyl cyclase domain. The natural agonists atrial and brain natriuretic peptides (ANP, BNP) bind and activate NPRA, leading to cyclic GMP production, which is responsible for their role in cardiovascular homeostasis. Prev...

Native mass spectrometry (MS) and top-down electron-capture dissociation (ECD) combine as a powerful approach for characterizing large proteins and protein assemblies. Here, we report their use to study an antibody Fab (Fab-1)-VEGF complex in its near-native state. Native ESI with analysis by FTICR mass spectrometry confirms that VEGF is a dimer in solution and that its complex with Fab-1 has a...

episode, she experienced hemidystonia o of the face and extremities, accompan motor seizures with secondary genera seizures were uncontrolled with oral anti-ep treatment for the last month and she was a hospital. On physical examination, mild faci atrophy of the left side of the body and were noticed. Laboratory data were unremark To the Editor: Dyke-Davidoff-Masson syndrom was first described ...

UNLABELLED 99mTc-ethylcysteinate dimer (99mTc-ECD) SPECT imaging reportedly fails to show reflow hyperemia in patients with subacute stroke. This study attempts to determine the clinical usefulness of dynamic 99mTc-ECD SPECT in evaluating regional blood flow in subacute cerebral infarction and the kinetic behavior of 99mTc-ECD in infarct areas. METHODS 133Xe and consecutive dynamic and static...

A 24-year-old man with a cerebral infarct within the left middle cerebral artery (MCA) territory was enrolled in a study to assess the safety of autologous bone marrow mononuclear cell (BMMC) transplantation in patients with ischemic stroke (NCT00473057). His National Institutes of Health Stroke Scale score was 7. Computed tomography (Figure 1A) and technetium-99m ethyl cysteinate dimer (Tc ECD...

S-Adenosylmethionine synthetase from Escherichia coli is rapidly inactivated by N-ethylmaleimide. In the presence of excess N-ethylmaleimide inactivation follows pseudo first-order kinetics, and loss of enzyme activity correlates with the incorporation of 2 eq of N-[ethyl-2-3H]maleimide/subunit. Preincubation of the enzyme with methionine and the ATP analog adenylylimidodiphosphate reduced the ...

BACKGROUND AND PURPOSE Diabetes mellitus increases the risk of ischemic stroke. The aim of this study was to investigate the correlation between fasting plasma glucose (FPG) and changes in regional cerebral perfusion (CP) in subjects with DM. METHODS CP was assessed in 24 subjects (mean age 44+/-2.5 years) with type 1 diabetes mellitus by single photon emission computed tomography. RESULTS ...
