In the present investigation, the influence of retrieval condition on medullary damage in kidneys was assessed. The isolated perfused pig kidney was used to assess initial renal function from multiorgan donors or single organ donors after cold flush and 24 h cold storage preservation with two preservation solutions: Euro-Collins and University of Wisconsin solutions. Kidneys flushed with cold heparinized saline and immediately perfused were used as a control group. Kidneys were perfused for 90 min at 37.5 degrees C and renal perfusion flow rate, glomerular filtration rate, tubular reabsorption of Na+ and lactate dehydrogenase and N-acetyl-beta-D-glucosaminidase excretion were determined. Ischaemia reperfusion impairment was also determined by 1H NMR (proton nuclear magnetic resonance) spectroscopy. Renal function was significantly decreased in experimental groups when compared to the control group, but there was no significant difference between experimental groups after 24 h cold storage. The release of lactate dehydrogenase in the effluent and the urinary excretion of N-acetyl-beta-D-glucosaminidase were not significantly different after 24 h cold storage. The most relevant resonances determined by 1H NMR spectroscopy were citrate, trimethylamine-N-oxide, lactate, acetate and amino acids. Excretion of these markers was significantly different when compared to biochemical markers. A resonance P (Peak) detected particularly in Euro-Collins solution multiorgan donors after 24 h cold storage was identified and well correlated to renal dysfunction. N-acetyl-beta-D-glucosaminidase spectroscopy, which is a non-invasive and non-destructive technique, is more efficient to assess renal damage than conventional histology and biochemical analysis. 相似文献

Foods have always been considered by man as a means of ensuring his physiological needs, allowing the growth, development and preservation of the body and its tissues (nutritional value of food). To this can be added the feelings of satisfaction and well-being that food gives to its consumer, thus constituting an element that is fundamental for our physiological and mental balance (the sensorial value of food).Nevertheless, recent scientific studies have shown that over and above the ensuring of nutritional needs, eating habits can also adjust certain functions of the human organism and thus play a beneficial or harmful role on one's health (the functional value of food).The whole concept of nutrition has been enriched by the notion that eating is not only a survival reflex (satisfaction derived through eating and the avoidance of harmful effects due to eating deficiencies or excesses): eating aims to improve one's health and well-being and to reduce the risk of developing various pathologies. These new data open interesting new horizons in today's context where health is increasingly expensive and people are increasingly concerned to improve their quality of live. 相似文献

Background
We conducted a monocentric retrospective study of patients with myelodysplastic syndromes (MDS) and autoimmune or inflammatory disorders (AIMs) and a literature review. We analyzed the association with subgroups of the WHO 2016 MDS classification and patient's survival in a case control study. Risk factors associated with survival were analyzed by uni- and multivariate analysis.Results
From all MDS patients 11% presented with AIMs. These were heterogeneous and the most frequent where polyarthritis (25%) and autoimmune cytopenias (17%). No difference for frequency and type of AIMs was observed for the WHO 2016 MDS subgroups (p?=?.3). In the case control study WHO classification, karyotype abnormalities, IPSS-R and IPSS were similar in both groups. The overall survival from MDS diagnosis was better in the group with AIMs [10.3?±?0.6 (IC95% 6.2–12.9) versus 4.8?±?1.1?years (IC95% 4.2–8.7), p?=?.04]. The better survival was restricted to MDS with low or intermediate-1 IPSS [11.1?±?1.5 (IC95% 9.9-NR) versus 8.7?±?1.3?years (IC95% 4.8–10.3), p?=?.006]. The better survival was only observed when AIMs diagnosis was timely associated or appeared after MDS diagnosis (p?=?.04). Factors associated with a better overall survival and survival without AML were steroid dependence [respectively HR?=?0.042, p?=?.003, (IC95% 0.005–0.33) and HR?=?0.07, p?=?.002, (IC95% 0.013–0.39)], a diagnosis of AIMs and MDS timely associated [respectively HR?=?0.05, p?=?.009, (IC95% 0.006–0.478) and HR?=?0.1, p?=?.008, (IC95% 0.018–0.54)] or a diagnosis of AIMs after MDS [respectively HR?=?0.024, p?=?.009, (IC95% 0.001–0.39) and HR?=?0.04, p?=?.008, (IC95% 0.003–0.43)].Conclusion
Autoimmune and inflammatory diseases associated to MDS are heterogeneous. AIMs diagnosed after or concomitantly to MDS seems associated with a better survival. Prospective studies are necessary to demonstrate that autoimmunity is associated to a better control of the MDS clone. 相似文献6.

Dendritic cells (DC) are a group of potent antigen-presenting cells (APC) specialized for initiating T cell immune responses. They originate from the bone marrow and upon stimulation with bacterial products, cytokines or CD40 ligation they acquire the ability to migrate to the secondary lymphoid organs. In vitro DC can be generated from human CD34(+) bone marrow cells and CD14(+) peripheral blood monocytes after culture with different cytokine combinations. Since most leukemic cells and tumors in general are devoid of APC capacities, various strategies have been used to increase their recognition and confer the capacity of antigen presentation on them. Because of our interest in the design of vaccine immunotherapy protocols for the adjuvant treatment of patients with lymphoid malignancies (LM), we chose to explore the capacity of human acute lymphoblastic leukemia, chronic lymphocytic leukemia and plasma cell leukemia to differentiate into cells with APC and DC features. Our results among a sample of 10 patients demonstrate that such approach is feasible. Leukemic cells could be induced in the presence of IL-4 and CD40L to exhibit a DC morphology with a phenotype of mature DC-like cells. They could also induce a potent proliferative response in naive CD4(+) T cells. In addition, they expressed chemokine receptor CCR7 and CD62L, and could drive T cells towards a T(h)1 response with secretion of IFN-gamma. Our strategy leading to increased LM cell immunogenicity may have potential clinical applications and LM appear to be attracting candidates for adjuvant vaccination and adoptive immunotherapy. 相似文献

The classification of hypertrophic cardiomyopathies remains a thorny nosological problem. Within this extensive diagnostic group, it is felt that the very special sub-group of "Japanese" apical hypertrophic forms must be subject to the strictest possible criteria in order to avoid improper use. The case reported here of biventricular apical hypertrophic cardiomyopathy in a 60-year-old woman with a family history of HCM, in whom the clinical, ECG and above all angiographic features were typically those of AHCM but where the existence of an intraventricular gradient was found during challenge manoeuvres emphasises this classification problem. Pseudo-AHCM in a context of OCM or pseudo-OCM in a context of AHCM? The discussion is not merely of nosological interest in view of the recently documented clear prognostic differences between these two conditions. Main series from the literature are reviewed. 相似文献
