Non-immune hydrops fetalis: Two case reports
2021
BACKGROUND Fetal hydrops is a serious condition difficult to manage, often with a poor prognosis, and it is characterized by the collection of fluid in the extravascular compartments. Before 1968, the most frequent cause was the maternal-fetal Rh incompatibility. Today, 90% of the cases are non-immune hydrops fetalis. Multiple fetal anatomic and functional disorders can cause non-immune hydrops fetalis and the pathogenesis is incompletely understood. Etiology varies from viral infections to heart disease, chromosomal abnormalities, hematological and autoimmune causes. CASE SUMMARY A 38-year-old pregnant woman has neck lymphoadenomegaly, fever, cough, tonsillar plaques at 14 wk of amenorrhea…
�ber den Stoffwechsel von radioaktiv markiertem Xylit bei der Ratte
1964
Verfuttert man erstmalig an Ratten14C-Xylit, so werden rund 60% der Substanz mit einer Halbwertszeit von 400 min oxydiert und als14CO2 ausgeatmet. Fur die Resorption bei erstmaliger Gabe haben wir eine Halbwertszeit von 7±1 Std ermittelt. Gibt man im Anschlus an eine Gewohnung an Xylit ein markiertes Praparat so werden fast 70% der Aktivitat mit einer Halbwertszeit von 230 min oxydiert und die Umsatzgeschwindigkeit hat sich verdreifacht. Eine ahnliche Steigerung erfahrt die Umsatzgeschwindigkeit im experimentellen Diabetes. Bei parenteraler Verabreichung des Xylits liegt der oxydierte Anteil bei 50%, wahrend die im Harn ausgeschiedene Aktivitat hoher liegt als bei peroraler Gabe. Die bei pa…
Die Vertr�glichkeit von Xylit beim Diabetiker
1963
In Doppelbelastungsversuchen bekamen Diabetiker und Nichtdiabetiker zweimal in 30 min Abstand 5 oder 8,75 g Xylit intravenos. Blutzuckerspiegel und Xylitspiegel im Blut wurden in verschiedenen Zeitabstanden gepruft. Xylitausscheidung im Harn und Glucoseausscheidung wurden bestimmt. Auf die Xylitbelastungen erfolgte kein Blutzuckeranstieg. Zwischen Diabetikern und Nichtdiabetikern ergaben sich keine Unterschiede. In allen Fallen wurden die Xylitinjektionen gut vertragen.
Stoffwechseluntersuchungen bei intraven�ser Cholintherapie
1949
Wahrend der Blutzuckerspiegel bei Gesunden und Kranken mit einer leichten bis mittelschweren Hepatitis epidemica auf intravenose Zufuhr von Methionin keinerlei Veranderungen zeigt, wurde bei Fallen von schwerer Hepatitis mit beginnendem Coma hepaticum der Blutzucker deutlich gesenkt.
Pre-Exercise Blood Glucose Levels Determine the Amount of Orally Administered Carbohydrates during Physical Exercise in Individuals with Type 1 Diabe…
2019
The aim of the study was to assess the amount of orally administered carbohydrates needed to maintain euglycemia during moderate-intensity exercise in individuals with type 1 diabetes. Nine participants with type 1 diabetes (four women, age 32.1 ±
Genetic variations of leptin and leptin receptor are associated with body composition changes in response to physical training
2010
Leptin regulates body weight, metabolism, and tissue adaptations to environmental stressors. We examined the association of single nucleotide polymorphism (SNP) of leptin promoter G-2548A (rs7799039) and leptin receptor Gln223Arg (rs1137101) with body composition, plasma leptin levels, and peak oxygen uptake (VO(2)peak) in response to 8 weeks of physical training in 48 male military conscripts. AA homozygotes of leptin promoter SNP-2548 showed higher body fat and BMI values than G allele carriers. Acute exercise decreased leptin levels in G allele carriers, but increased in AA homozygotes. Physical training significantly decreased BMI values and also a tendency for decreased plasma leptin l…
Reproducibility and Validity of a Short Food Frequency Questionnaire for Dietary Assessment in Children Aged 7–9 Years in Spain
2019
The purpose of this study was to examine if the short semi-quantitative food frequency questionnaire (FFQ) is a reliable and valid tool to assess the diet of Spanish children aged 7&ndash
Retinal and choroidal vasculature changes associated with chronic kidney disease
2018
Retinal and choroidal microvascular changes can be related to renal impairment in hypertension and chronic kidney disease (CKD). The study examines the association between retinochoroidal parameters and renal impairment in hypertensive, non-diabetic patients. This is a cross-sectional study on Caucasian patients with systemic arterial hypertension with different levels of renal function. All subjects were studied by blood chemistry, urine examination, microalbuminuria and blood pressure. Complete eye examination was completed with swept source optical coherence tomography (SS-OCT) and optical coherence tomography angiography (OCTA) scans of macular region. Patients were divided in groups: L…
Obese Rats Exhibit High Levels of Fat Necrosis and Isoprostanes in Taurocholate-Induced Acute Pancreatitis
2012
BACKGROUND: Obesity is a prognostic factor for severity in acute pancreatitis in humans. Our aim was to assess the role of oxidative stress and abdominal fat in the increased severity of acute pancreatitis in obese rats. METHODOLOGY: Taurocholate-induced acute pancreatitis was performed in lean and obese Zucker rats. Levels of reduced glutathione, oxidized glutathione, L-cysteine, cystine, and S-adenosylmethionine were measured in pancreas as well as the activities of serine/threonine protein phosphatases PP1 and PP2A and tyrosin phosphatases. Isoprostane, malondialdehyde, triglyceride, and free fatty acid levels and lipase activity were measured in plasma and ascites. Lipase activity was m…
High Levels of Asymmetric Dimethylarginine Are Strongly Associated with Low HDL in Patients with Acute Myocardial Infarction
2013
International audience; Objectives: Low levels of high-density lipoprotein (HDL) cholesterol are associated with an increased risk of acute myocardial infarction possibly through impaired endothelial atheroprotection and decreased nitric oxide (NO) bioavailability. Asymmetric dimethylarginine (ADMA) mediates endothelial function by inhibiting nitric oxide synthase activity. In patients with acute myocardial infarction, we investigated the relationship between serum levels of HDL and ADMA. Approach and Results: Blood samples from 612 consecutive patients hospitalized for acute MI ,24 hours after symptom onset were taken on admission. Serum levels of ADMA, its stereoisomer, symmetric dimethyl…
