Oxygen and glucose deprivation induces major dysfunction in the somatosensory cortex of the newborn rat
2005
The mechanisms and functional consequences of ischemia-induced injury during perinatal development are poorly understood. Subplate neurons (SPn) play a central role in early cortical development and a pathophysiological impairment of these neurons may have long-term detrimental effects on cortical function. The acute and long-term consequences of combined oxygen and glucose deprivation (OGD) were investigated in SPn and compared with OGD-induced dysfunction of immature layer V pyramidal cortical neurons (PCn) in somatosensory cortical slices from postnatal day (P)0-4 rats. OGD for 50 min followed by a 10-24-h period of normal oxygenation and glucose supply in vitro or in culture led to pron…
Beurteilung der entzündlichen Aktivität des M. Crohn mit der Hydro-MRT∗
2000
PURPOSE: To assess the value of hydro-MRI in the assessment of the activity of Crohn's disease. MATERIALS AND METHODS: After an oral bowel opacification using 1000 ml of a 2.5% mannitol solution, axial and coronal breath-hold sequences (T2W HASTE +/- FS, contrast-enhanced T1W FLASH FS) were acquired in 63 patients with Crohn's disease at 1.0 T. The enhancement of the bowel wall was correlated with other MRI findings, with the Crohn's disease activity index (CDAI), and the C-reactive protein (CRP). RESULTS: In Crohn's disease, contrast enhancement of the affected bowel wall is markedly increased in comparison with the normal bowel wall (+80 +/- 23% vs. +43 +/- 11%; p = 8 x 10(-11)). Positive…
Hepatic Sinusoidal Dilatation: A Review of Causes With Imaging-Pathologic Correlation.
2016
Hepatic sinusoids are vascular conduits connecting the portal triad with the central vein. Multiple conditions can lead to sinusoidal dilatation and congestion with resultant stasis of blood within the lumen. The altered hemodynamics associated with hepatic sinusoidal dilatation generally result in heterogeneous enhancement of the hepatic parenchyma on contrast-enhanced computed tomography and magnetic resonance imaging, a pattern often described as “mosaic” enhancement. In this article, we review the causes of hepatic sinusoidal dilatation and the imaging manifestations on contrast-enhanced computed tomography and magnetic resonance.
Correlation of skeletal muscle blood oxygenation level-dependent MRI and skin laser doppler flowmetry in patients with systemic sclerosis
2013
Purpose To investigate the origin of skeletal muscle BOLD MRI alterations in patients with systemic sclerosis (SSc) by correlating BOLD MRI T2* signal of calf muscles with microcirculatory blood flow of calf skin measured by laser Doppler flowmetry (LDF). Materials and Methods BOLD MRI (3T) and LDF measurements were performed in 12 consecutive SSc patients (6 women, 6 men; mean age 54.0 ± 10.0 years) and 12 healthy volunteers (4 men, 8 women; mean age 44.7 ± 13.1 years). For both modalities, the same cuff compression paradigm at mid-thigh level was used. LDF datasets were acquired using a PeriScan PIM II Imager (Perimed AB, Stockholm, Sweden) at the upper calf corresponding to the level of …

987 Emipediology and Morbidity of Late Preterm Neonates in Correlation with Maternal Risk Factors in Hessen, Germany
2012
Short and long term morbidity in late preterm neonates (LP) and their correlation to maternal risk factors are relevant as shown in multiple studies in North America and European countries. Epidemiological studies showed an increase in LP birth over time. Corresponding data for Germany have not yet been published. Our goal was to evaluate the epidemiology of LP over a 7 year period and the correlation to potential maternal risk factors in Hessen, Germany. Data was collected from the perinatal und neonatal quality assurance in Hessen form 2001 to 2007. For some calculations the two data sets were merged. Overall the data sets of 360.000 births and 44.000 neonatal hospitalizations were availa…
Eine vergleichende Untersuchung zum Reizdarmsyndrom bei konsekutiven Patienten zweier internistischer Ambulanzen
2001
OBJECTIVES We investigated the nature of illness behavior and the meaning of emotional deficiencies during childhood in patients with irritable bowel diseases (IBS). DATA A consecutive study in two tertiary referral centers was conducted with 48 patients suffering from irritable bowel diseases (IBS) and 91 patients with inflammatory bowel disease (IBD). METHODS The diagnosis of IBS was made by following the Manning criteria, a positive diagnosis of IBD was established through physical, endoscopic and radiologic examinations and was confirmed histologically. Psychological data were obtained by structured psychiatric interviews and psychological self-report measures (GBB). RESULTS We found th…
Long-term prediction of birth weight
1993
On the basis of the hypothesis that undisturbed individual growth in fetal life keeps a constant proportional difference with the standard population 50th percentile, birth weight can be predicted with a single sonographic exploration after the 16th week of pregnancy. Data on 135 singleton pregnancies with accurate dates and delivery at term were used. Sonography was performed between the 17th and 36th weeks of pregnancy, in every case at least 4 weeks before delivery. The observed measurements of BPD, FL, and AC were used for the prediction of their values on the day of delivery, applying the Hadlock equation for the estimation of birth weight. The mean error of birth weight predictions wa…
Antipsychotic drugs antagonize human serotonin type 3 receptor currents in a noncompetitive manner
2004
The serotonin type 3 (5-HT(3)) receptor is the only ligand-gated ion channel receptor for serotonin (5-HT). 5-HT(3) receptors play an important role in modulating the inhibitory action of dopamine in mesocorticolimbic brain regions. Neuroleptic drugs are commonly thought to exert their psychopharmacological action mainly through dopamine and serotonin type 2 (5-HT(2)) receptors. Except for clozapine, a direct pharmacological interaction of neuroleptics with 5-HT(3) receptors has not yet been described. Using the concentration-clamp technique, we investigated the effects of flupentixol, various phenothiazines, haloperidol, clozapine and risperidone on Na(+)-inward currents through 5-HT(3) re…
Impact of a social media exercise service on individuals and employees
2016
Summary Study aim: The purpose of the present study was to investigate the impact of a social media exercise platform (HeiaHeia, Helsinki, Finland) on the level of physical activity, physical fitness, wellbeing and body weight of the service users. Material and methods: The subject group consisted of 2862 individuals who voluntarily participated in a web survey. Their age, gender, body mass index, physical fitness level and activity information were self-reported. Results: Most of the service users (78.1%) exercised more than three times a week. About 75% of the users reported that they were in good or excellent physical fitness, while about 50% were overweight. More than half (64.6%) of th…
