Activity of acid hydrolases in skeletal muscle of untrained, trained and detrained mice of different ages.
1978
The activities of p-nitrophenylphosphatase, beta-glucuronidase and beta-N-acetylglucosaminidase from crude skeletal muscle homogenates of 4 and 7 months old mice were assayed after short-term intensive and long-term moderate training and after terminated training. In the older untrained mice the activity of the hydrolases was higher than in the younger mice. The level increased with training and this increase was far more pronounced in the older animals. Cessation of training for 7 and 21 days decreased this activity in the older animals but it was again increased 42 days later and close to the level observed in the trained mice. In young mice 3 days' terminated training increased the activ…
Steroid activities comparison of natural and food wrap compounds in human breast cancer cell lines
2004
Abstract In this study, we tested and compared the endocrine disruption activities of compounds in materials used to package foods (bisphenol A, bisphenol F, and bisphenol A diglycidylether BADGE) with natural molecules (genistein, apigenin, kaempferol, and tangeretin) in the human breast cancer cell lines MCF-7 (ER + ) and MDA-MB453 (AR + ; GR + ). Octylphenol was also chosen as a xenoestrogen reference. Two compounds had no estrogenic activity: BADGE and tangeretin. Genistein was the most active compound in the E-Screen assay with MCF-7, followed by octylphenol, bisphenol F, bisphenol A and apigenin, with kaempferol the least potent. All estrogenic compounds competed with 17β-estradiol fo…

2013
Objectives To capture an accurate contemporary description of the practice of pulmonary metastasectomy for colorectal carcinoma in one national healthcare system. Design A national registry set up in Spain by Grupo Espanol de Cirugia Metastasis Pulmonares de Carcinoma Colo-Rectal (GECMP-CCR). Setting 32 Spanish thoracic units. Participants All patients with one or more histologically proven lung metastasis removed by surgery between March 2008 and February 2010. Interventions Pulmonary metastasectomy for one or more pulmonary nodules proven to be metastatic colorectal carcinoma. Primary and secondary outcome measures The age and sex of the patients having this surgery were recorded with the…
Complement activation by oxidatively modified low-density lipoproteins
1999
Background Oxidatively modified low-density lipoproteins (LDLs) have been implicated in the pathogenesis of atherosclerosis and are found in human vascular lesions. There is increasing evidence that complement activation may also play a role in atherogenesis. Activated complement proteins have been demonstrated to be present in early atherosclerotic lesions, and lipids isolated from lesions have been shown to activate complement, hence their designation as lesion complement activator (LCA). The question now arose whether oxidized LDLs would also activate complement. Material and methods The complement-activating capacity of a lesion complement activator preparation and of minimally as well …
Reference values for mean overnight saturation in sleep apnoea – the European Sleep Apnoea Database (ESADA)
2020
Introduction: Normative values for mean overnight oxygen saturation during sleep in apnoea patients stratified for age, BMI, and sleep apnoea severity are lacking. Aim: To establish reference intervals for overnight mean saturation in a large sleep apnoea patient cohort. Methods: Mean overnight oxygen saturation was analysed in adult patients (n=23,220) from the European Sleep Apnoea Database (ESADA, 30 sleep centres, 18 European countries). Data were classified according to age, gender, BMI ( Results: Mean overnight saturation was 93.0% (95% confidence interval (CI) 92.9 to 93.1%). Age influenced the adjusted mean nocturnal saturation (93.6%, 93.2%, 92.9%, 92.5%, 92.2% and 91.9% for those …
Potential involvement of fas and its ligand in the pathogenesis of Hashimoto's thyroiditis
1997
The mechanisms responsible for thyrocyte destruction in Hashimoto's thyroiditis (HT) are poorly understood. Thyrocytes from HT glands, but not from nonautoimmune thyroids, expressed Fas. Interleukin-1β (IL-1β), abundantly produced in HT glands, induced Fas expression in normal thyrocytes, and cross-linking of Fas resulted in massive thyrocyte apoptosis. The ligand for Fas (FasL) was shown to be constitutively expressed both in normal and HT thyrocytes and was able to kill Fas-sensitive targets. Exposure to IL-1β induced thyrocyte apoptosis, which was prevented by antibodies that block Fas, suggesting that IL-1β-induced Fas expression serves as a limiting factor for thyrocyte destruction. Th…
Therapy with non-invasive ventilation in patients with obstructive sleep apnoea: effects on atherogenic lipoprotein phenotype.
2009
Patients with obstructive sleep apnoea are at increased risk of atherosclerotic morbidity and mortality. Abnormalities in lipid metabolism that occur in response to chronic intermittent hypoxia in patients with sleep-disordered breathing may increase the cardiovascular risk in an already susceptible population. Atherogenic lipoprotein phenotype and small, dense LDL have an independent predictive role for future cardio- and cerebro-vascular events in patients with the metabolic syndrome. Therefore, testing the hypothesis that therapy of obstructive sleep apnoea may reduce atherogenic lipoprotein phenotype might have significant clinical implications. We suggest that abolition of obstructive …
Translocation (10;11;22)(p14;q24;q12) Characterized by Fluorescence in Situ Hybridization in a Case of Ewing's Tumor
2001
It is well recognized that the identification by classic cytogenetics of t(11;22)(q24;q12) is a useful aid in the accurate diagnosis of Ewing's sarcoma and related tumors. This translocation induces the EWS/FLI-1 fusion transcript, which can be detected by reverse transcription-polymerase chain reaction. Recent studies have also used fluorescence in situ hybridization (FISH) to demonstrate the translocation. The authors coupled classic cytogenetics and FISH on tumor cells from the original specimen, the local recurrence, and the pulmonary metastasis as well as from the xenografted tumors in a case of extraosseous Ewing's sarcoma. FISH analysis not only confirmed the cytogenetic results but …
The neuro-B cell link of peptidergic innervation in the Bursa Fabricii
1991
The Bursa Fabricii, restricted to birds, specifically provides the microenvironment for B-cell maturation. The presence of nerve fibers containing immunopotent neuropeptides in immune organs opens interesting perspectives on the understanding of neuroimmune communication. As an organ for the development of only B-lymphocytes is not known in mammals, the contribution of a peptidergic innervation to the microenvironment of B-cells is not known. Therefore, we studied the peptidergic innervation of the Bursa Fabricii as an organ of B-cell maturation. Four different neuropeptides were found in nerve fibers of the Bursa Fabricii: tachykinins (TK), vasoactive intestinal peptide (VIP), galanin (GAL…
Fresh cell therapy followed by fatal coma
1986
A 60-year-old woman received a 3-day course of nine injections of “fresh” cells from fetal lamb ovary, placenta, brain (hypothalamus) and liver. There were no immediate complications, but a few days later she developed headache, fever and hemiparesis. She subsequently fell into a coma and died 3 weeks after her fresh cell therapy and 2 weeks after the onset of her clinical symptoms. Autopsy revealed perivenous leucoencephalopathy with a probably steroid-treatment-induced paucity of perivascular inflammation. Fresh cell therapy, clinical symptomatology and morphological findings suggest, though do not prove, that this patient's monophasic and probably immune-mediated disease is a rare and fa…
