Non-cases were considered as reports containing other adverse reaction terms than lupus-like syndrome cheap chloroquine 250mg without prescription medications diabetic neuropathy, including other autoimmune drug reactions order chloroquine 250 mg fast delivery treatment definition math. Definition of Exposure Exposure to statins was defned as reports in which the reporter suspected that a prescribed statin was a causal factor in the development of lupus-like syndrome. Statistical Analysis Characteristics of the cases and non-cases were analysed, using Student’s t test or Chi-square test. Means and standard deviations or percentages were obtained for continuous and categorical variables, respectively. Covariates that acted as confounders were included in the model if each of them induced a change of crude β estimates of the exposure-outcome association of at least 10% 26. All tests were 2-sided with a rejection of the null hypothesis at a p value of less than 0. The distribution of baseline characteristics for the cases of lupus-like syndrome and non-cases is shown in Table 3. The use of anti- arrhythmic drugs, antihypertensive agents and non-steroidal anti-infammatory drugs was more frequently reported in cases of lupus-like syndrome than in non-cases. Table 4 shows the characteristics of 106 cases of lupus-like syndrome with reported statins as suspected drug. Most of these cases were reported in the early 1990s and originated from the United States of America. Lovastatin and simvastatin were more often reported as the suspected drug for the occurrence of lupus-like syndrome than other types of statins. The range of time to onset of lupus-like syndrome after starting statins was 1 day to 15. Of the 106 reported cases, 14 listed recovery of lupus-like syndrome, while 17 listed no recovery of lupus-like syndrome. Of these 45 cases where statins were withdrawn, 35 listed that lupus-like syndrome abated, while 6 listed no effect. Of the specifc 35 cases who reported that lupus-like syndrome abated on withdrawal of statins, 7 cases reported recovery, whereas 2 cases reported no recovery. Seven cases reported a rechallenge with statins of which four resulted in the recurrence of lupus-like syndrome. Our fndings were relatively insensitive to variations in the defnition of lupus- like syndrome and the inclusion of reports that listed concomitant use of statins. Several published case reports support the notion that statins could facilitate the development of lupus-like syndrome. The cases in our study and the patients described in the published case reports were, on average, 50 years of age and predominantly female. Based on the case reports in the medical literature, the course of lupus-like syndrome varies from case to case. Clinical improvement was seen in some patients within weeks after discontinuation of statins, while other cases showed clinical improvements only after treatment with immunosuppressive therapy. In several case reports of lupus-like syndrome in the literature, the auto-antibodies remained positive months after withdrawal of statins despite clinical improvements. Hence, the true underlying mechanism of statin-induced lupus-like syndrome is unclear, although in vitro and animal studies demonstrated that statins may exacerbate or trigger cellular apoptosis 27,28 and induce a shift in the T helper (Th) 1/Th2 balance leading to B-cell reactivity and production of pathogenic auto-antibodies 29,30. Recent studies have suggested that Treg cells can be unstable in the periphery and may promote autoimmunity 31,32. To control for possible time trends of reporting, we matched the non-cases for the calendar year of reporting. Since lupus-like syndrome and cardiovascular risk factors such as hyperlipidaemia often coexist 38,39, and the diagnosis of lupus-like syndrome is often diffcult to assess, lupus-like syndrome may already be present before the start of statin therapy. Data on the medical history of the patient are not available in the reports, making it impossible to control for protopathic bias. We did not have explicit information on the criteria set for making a distinction between these diseases, and for diagnosing lupus-like syndrome in our study population.

The genetic engineering approach enables us to reduce the dependence on the natural resource for phytochemical production by pro- viding an alternative to extraction from plants [109] buy chloroquine 250 mg visa medications held for dialysis. Immature embryos selected from the seeds of superior trees under appropriate culture conditions can produce a mass of embryogenic tissues from which several thousands of somatic em- bryos can be obtained purchase chloroquine 250 mg fast delivery kapous treatment. Somatic embryogenesis and Agrobacterium-mediated genetic transformation have also been used to incorporate additional useful traits of herbicide and/or pest tolerance in tropical trees of Azadirachta excelsa [104]. The authors have attempted to develop methods for somatic embryogen- esis and gene transfer in Azadirachta excelsa. Methods for in vitro propagation of neem have been discussed by Joshi and Thegane [110]. There have been reports on in vitro regeneration of Azadi- rachta indica plantlets from various explants like axillary bud [111], immature embryos/seedlings [64, 69, 76], leaves [63, 66], cotyledons and hypocotyls [65], stem tissue [112], anther [40] and through direct and indirect somatic embryo- genesis and organogenesis [113, 114]. Further, somatic embryos have also been initiated with mature seeds of neem (Azadirachta indica A. In undifferentiated callus or suspension cultures, these accumulation sites are missing. This is probably the reason for low yields of such compounds reached in these plant cell cultures. The addition of an artifcial site for the accumulation of secondary metabolites has been shown to be an effective tool for increased productivity in plant cell cultures. If the formation of a product is subject to feedback inhibition or intracellular degradation, the removal and sequestering of the product in an artifcial com- partment may increase metabolite production [84]. For them, a two- stage process can prove to be benefcial for enhanced metabolite production. In general, cell immobilisation provides a continuous process operation, reuse of biocata- lysts, separation of growth and production phases, and a simplifed separation of biocatalysts from the culture medium, which allows product-oriented op- timisation of the medium and reduction of cultivation periods [116]. It has Chapter 12 In Vitro Azadirachtin Production 249 been observed that immobilisation either through gel entrapment or surface adsorption enhances productivity and prolongs the viability of cultured cells [84]. As far as application of this strategy for enhanced azadirachtin produc- tion is concerned, there are no reports available to date. Systematic studies are needed in order to exploit this technique for increased azadirachtin production from plant cell/tissue cultures. Due to the pres- ence of acid-sensitive groups like tertiary hydroxyls, a ketone group and a di- hydrofuran ring azadirachtin is highly unstable under acidic conditions, while the presence of four ester groups makes it equally unstable in alkaline condi- tions. In addition to these chemical factors, various physical parameters such as temperature, light and humidity are known to affect the molecule, which leads to its rapid decomposition. It has also been reported that interaction between various solvent molecules with active functional groups of azadirachtin could result in chemical changes in the molecule. The stability of azadirachtin has been studied extensively under various storage conditions. Studies on increasing the half-life of azadirachtin using chemicals, fatty acids, oils, surfactants and organic solvents have been reported in the literature [47, 118, 119]. This is due to the lack of sophisticated technology for the commercial production of plant tissue culture products and the consequent ex- pense of available production methods. The development of large-scale cultiva- tion processes is complicated because of several specifc characteristics of plant cells. Bioreactors are considered to be the key step towards the commercial pro- duction of secondary metabolites by plant cell technology. They offer optimal conditions for large-scale, plant-derived metabolite production for commercial manufacture [124, 125]. On-line measurement of process parameters such as temperature, pH, dissolved oxygen, carbon dioxide and other gases is possible during bioreactor operations. Hence, effcient control of parameters that affect growth and product synthesis can be achieved using the signals from the sen- sors mentioned above and various control strategies in the bioreactors. Srivastava the advantages, transfer from shake fask to pilot plant-scale bioreactor level is a problem because of the slow growth of plant cell/tissue, low shear resistance, and tendency towards cell/tissue aggregation. The choice and design of a biore- actor is therefore determined by factors like shear environment, oxygen trans- fer capacity, mixing mechanism, foaming, maintenance of aseptic conditions for long fermentation periods and capital investment.

Liver and Lung Transplantation Center, Ospedali Riuniti, Bergamo, Italy Introduction: Split liver transplantation has been adopted as an alternative to expand the organ donor pool. Material and Methods: Between October 1997 and October 2007 we performed a total of 372 liver transplants in 330. Among the 312 children who received a primary isolated liver transplant, 249 were transplanted with a split liver graft. Both ideal donors and donors beyond the ideal criteria for splitting have been used as well. The donors of a split liver graft were significantly older than those of a whole graft (mean ± sd 27,2 ± 15,9 vs 14,8 ± 19,5 p=0,0001). Biliary complications occurred in 30% of the recipients of a split liver graft and 3% of the recipients of a whole size graft (p < 0,0001). Among the recipients of a split graft 1 and 5 years patient / graft survival was 91%/84% and 87%/80% respectively. The recipients of a whole size graft had a 1 and 5 years patient / graft survival of 84%/78% and 83%/74%. The overall split liver grafts reached even better results of a whole liver graft in terms survival rates of graft at 1, 5, and 10 years were 87. Thus, the use of split grafts should be strongly and the survival rates of patient were 91.
