Effects of chronic alcohol consumption on enzyme activities and active methionine absorption in the small intestine of pregnant rats.
1996
The present study evaluates the effect of chronic alcohol intake on the intestinal transport of methionine during pregnancy. For this purpose, we have used an in vitro technique that allows measurement of the unidirectional influx of the amino acids across the brush-border membrane of the rat mid-jejunum, and the basolateral membrane enzyme Na+, K+-ATPase was also evaluated in the duodenum and jejunum. For chronic alcohol treatment, the rats were fed a liquid diet containing ethanol (36% of calories) or an isocaloric diet-(pair-fed control) for 5 weeks before and during pregnancy. Animals were killed at 21 days of gestation. Results from the kinetic analysis revealed that chronic ethanol tr…
Pharmacological treatment of sexual offenders in German outpatient treatment centers
2018
In Germany, depending on a sexual offender's culpability and the severity of the offence, he/she can be placed either in the forensic-psychiatric or the correctional system. Numbers related to the pharmacological treatment of sexual offenders for the correctional system are missing so far. In sexual offenders, the pharmacological treatment of paraphilic disorders is of special importance. The present study aimed at assessing the prevalence of pharmacological sexual offender treatment in German outpatient treatment centers supervising mainly clients from the correctional sector. An online questionnaire was sent to 112 outpatient treatment centers and 21 provided data relevant for the present…
Intracellular acidosis in murine fibrosarcomas coincides with ATP depletion, hypoxia, and high levels of lactate and total Pi
1994
Bioenergetic and metabolic status of murine FSaII tumours were evaluated using 31P MRS, acid extracts ('global' techniques) and quantitative bioluminescence ('microregional' assay). Data obtained from s.c. tumours of varying sizes (44-600 mm3) have been correlated with the oxygenation status evaluated using O2-sensitive needle electrodes. beta-NTP/Pi and phosphocreatine (PCr)/Pi ratios derived from 31P MRS were positively correlated to the median tissue pO2 values. pH declined during growth with intracellular acidosis being evident in tumours > 350 mm3. Whereas lactic acid formation greatly contributed to this decline in small- and medium-sized tumours, ATP hydrolysis and slowing down of th…
Hemodynamic effects of dobutamine in children with cardiovascular failure.
1982
The effect of dobutamine, a synthetic catecholamine, was studied in 12 patients aged one day to 14 years with low cardiac output syndromes. After initial stabilization of the patients dobutamine was administered by continuous infusion in a dosage of 7.5 or 10 μg/kg/min. Heart rate, cardiac output (using thermodilution technique and/or pulse contour method), mean systemic and mean pulmonary artery pressures were determined before and after the dobutamine infusion. Systemic and pulmonary vascular resistances, cardiac index and stroke volume index were calculated. Cardiac output and cardiac index increased significantly in every patient, whereas the heart rate changed only slightly, suggesting…
Elite athletes get pregnant, have healthy babies and return to sport early postpartum
2019
ObjectivesTo enhance knowledge on pregnancy and return to sport in the postpartum period in elite female athletes.Methods34 Norwegian elite athletes (33.1 years) and 34 active controls (31.5 years) were asked about training and competitive history, pregnancy-related issues, injuries, body dissatisfaction (BD), drive for thinness (DT), eating disorders (ED) and practical experiences, through a questionnaire and interview. Independent samples T-tests or χ² tests for between-group differences and paired-samples T-tests and repeated measures analysis of variance for within group differences were used.ResultsNo group differences in fertility problems, miscarriage, preterm birth or low birth weig…
Chronic consumption of an inositol-enriched beverage ameliorates endothelial dysfunction and oxidative stress in type 2 diabetes
2015
The anti-diabetic properties of an inositol-enriched beverage (IEB) on the endothelial function and redox status in diabetic subjects were assessed. This was a 12-week, double-blind randomized controlled trial employing thirty-eight diabetic subjects that were divided into two intervention groups: one receiving an IEB and the other a sucrose-enriched beverage. Subjects consuming IEB exhibited a significant decrease in triacylglycerol (8.82%) and HbA1c (4.53%) levels. Continuous glucose monitoring revealed a significant net reduction of 2.51 and 7.11% during postprandial and overnight fasting periods after consumption of IEB, respectively. Moreover, IEB improved endothelial function by reduc…
Postprandial metabolism: from research to clinical practice.
2013
Over the last decade, the importance of postprandial metabolism has increased, given that it is the physiological state of humans in modern society. Moreover, postprandial lipemia is considered as a key player in the development of the most important cardiometabolic diseases. In this regard, postprandial lipemia has become more important, since it has been demonstrated that nonfasting triglycerides (TGs) are independent predictors of the risk of cardio vascular disease (CVD) [1,2]. Interestingly, the postprandial phase has been associated with increased inflammation and oxidation, which influences vascular function through a permanent endothelial aggression by atherogenic lipoprotein. TGs a…
Effect of propylene glycol on pre- and post-partum performance by dairy ewes
2005
This study was carried out in order to determine the effects, after feeding propylene glycol to Valle del Belice ewes 30 days prepartum and 30 days postpartum, on metabolic profiles, body-condition score, milk yield, milk composition, milk clotting ability and the performance of suckling lambs. Ewes were blocked by parity, body-condition score and previous milk production, and assigned randomly to either a control diet or a diet containing propylene glycol fed at the rate of 80 g/ewe/day (low PG) or 160 g/ewe/day (high PG). Feeding propylene glycol prepartum decreased the concentration of BHBA and NEFA and increased the concentration of glucose in the ewes’ plasma. Milk yield from ewes fed …
Clinical and genetic characteristics of 21 Spanish patients with biallelic pathogenic SPG7 mutations.
2021
Spastic paraplegia type 7 (SPG7) is one of the most common hereditary spastic paraplegias. SPG7 mutations most often lead to spastic paraparesis (HSP) and/or hereditary cerebellar ataxia (HCA), frequently with mixed phenotypes. We sought to clinically and genetically characterize a Spanish cohort of SPG7 patients. Patients were recruited from our HCA and HSP cohorts. We identified twenty-one patients with biallelic pathogenic SPG7 mutations. Mean age at onset was 37.4 years (SD ± 14.3). The most frequent phenotype was spastic ataxia (57%), followed by pure spastic paraplegia (19%) and complex phenotypes (19%). Isolated patients presented with focal or multifocal dystonia, subclinical myopat…
Focal elevation of liver microsomal epoxide hydrolase in early preneoplastic stages and its behaviour in the further course of hepatocarcinogenesis.
1981
Abstract Treatment of rats with N-nitrosomorpholine (NNM) for 7 weeks led to a focal increase in liver microsomal epoxide hydrolase (EH) as early as 2 weeks after withdrawal of the carcinogen. This treatment also leads to hyperplastic nodules and liver tumors, but much later. At the same early time point, ATPase activity was decreased in the same islands. Most of these areas already had increased γ-glutamyltranspeptidase activity. The increase in EH at this early time point was more distinct than the decrease in ATPase which has thus far been considered a suitable marker of the earliest stages in hepatocarcinogenesis. The focal increase in EH was also observed in all benign hepatomas, but n…
