Approximately 25% of smokers are believed to be susceptible to developing the disease, suggesting that there are at present unknown genetic, epigenetic and/or environmental factors which underlie an individual's risk for developing the disease. COPD is a multifactorial disease and susceptibility is therefore likely to be determined by the expression of a number of allelic variants that leave an individual less capable of handling the damaging effects of chronic smoking. It is proposed herein that intrinsic aerobic (exercise) capacity is the primary trait which determines an individual's risk for developing this disease. This polygenetic characteristic comprises an individual's ability to metabolize oxygen and detoxify its reactive species. Pathways regulating these processes are damaged by smoking; thus individuals with low...","PeriodicalId":89424,"journal":{"name":"Journal of organ dysfunction","volume":"16 1","pages":"218-223"},"PeriodicalIF":0.0,"publicationDate":"2009-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78962185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Material and methods. In this prospective observational pilot study we measured EA in 40 patients undergoing OLT or MVT during the perioperative period. As a control, the EAA was performed on 10 healthy adult volunteers. We analyzed the relationships between EA and graft function, episodes of rejection, infection and outcome. Results.

Transforming growth factor (TGF)-β is a key factor in these alterations either directly, by stimulating synthesis of extracellular matrix components and/or impairing turnover of extracellular matrix, or indirectly, through other profibrogenic factors such as connective tissue growth factor. TGF-β is important for the proliferation of renal interstitial fibroblasts and the epithelial–mesenchymal transition, through which tubular cells acquire fibroblastic properties. In addition, TGF-β can modulate the immune response in inflammatory renal diseases. Many humoral factors induce TGF-β expression in the kidney, chief among them being various members of the renin–angiotensin–aldosterone system. Proof of the concept that TGF-β is the main mediator of renal fibrosis stems originally from experimental and clinical observations in diabetic nephropathy, and more recently...","PeriodicalId":89424,"journal":{"name":"Journal of organ dysfunction","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2009-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86870067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the mechanisms of the pathogenesis of COPD have not been completely elucidated to date. Transforming growth factor (TGF)-β is a pleiotropic, multifunctional cytokine participating in cell differentiation, apoptosis, survival and proliferation. TGF-β is involved in many diseases, including carcinogenesis and fibrosis. Although the most important risk factor for COPD is cigarette smoking, only 10–15% of all smokers develop the disease. This finding raises suspicion that some host or genetic factors may be involved in the pathogenesis of the disease. Thus, special attention has recently been focused on the role in COPD of TGF-β, which is active in inflammation of the airways and particularly in lung remodeling. TGF-β induces chemotaxis of mast cells and macrophages, regulates cell apoptosis and influences the protease/antiprotease balance inhibiting matrix metalloproteinase-9.

Leukotrienes play an important role in the innate defense system, in the antimicrobial defense system, and in intercellular signaling. Under pathophysiological conditions, overproduction of LTB4 was noted in multiple cells. It is known that 5-LO and its production of LTB4 are involved in the maintenance of normal host defense, initiation of inflammation, migration of leukocytes, development of endothelial barrier dysfunction, hyperresponsiveness of smooth muscle cells, stimulation of mucus secretion, reduction of mucociliary clearance, and tissue remodeling.

An association between alcohol exposure and traumatic injury has been recognized in many studies. The gut is the major reservoir of bacteria within the body but, under healthy conditions, it maintains a barrier which prevents these bacteria from crossing the intestinal lumen. The findings reviewed herein indicate that this barrier is lost in conditions such as major trauma and alcohol exposure. Furthermore, studies also indicate that alcohol intoxication at the time of injury causes a further deterioration in intestinal barrier function as determined by intestinal permeability and bacterial translocation. A precise mechanism for impaired barrier function following alcohol exposure, either alone or in combination with major trauma or burn injury, remains unknown. However, the findings discussed in this article indicate that this could result from: (i) an increase in bacterial growth; (ii) a decrea...","PeriodicalId":89424,"journal":{"name":"Journal of organ dysfunction","volume":"30 1","pages":"171-181"},"PeriodicalIF":0.0,"publicationDate":"2009-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88639501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

TGF-β family members also play an important role in cell-cycle regulation. Through induction of cyclin-dependent kinase inhibitors, TGF-β promotes a hypertrophic response of renal tubular epithelial cells and glomerular mesangial cells. This TGF-β-driven hypertrophic response, which occurs in diabetic nephropathy, may have deleterious effects on the kidney. In contrast, many human cancers are associated with loss of the growth inhibitory effects of TGF-β. TGF-β may promote or inhibit inflammation, an outcome which appears to depend on the cell type(s) involved and on potential interactions with other signaling pathways that regulate inflammatory responses.

Although, initially, aspects of this response are likely to be advantageous, the relentless loss of lean tissue and protein-wasting soon become functionally important, leading to increases in morbidity and mortality. Because standard nutritional support does little to limit protein-wasting in patients with MODS, investigators have sought to develop alternative treatment strategies. Amongst the many factors implicated in the adverse effects of prolonged catabolism, the role of the hypothalamic–anterior–pituitary axis has stimulated considerable research and debate. In view of the well-documented anabolic properties of growth hormone, the efficacy of treatment with recombinant human growth hormone (rhGH) has been extensively investigated in the critically ill.
