.The fig leaf roller or Fig-tree Skeletoniser, Choreutis nemorana (Lep.: Choreutidae), is a destructive pest of fig trees found in some fig-growing areas of Iran. The larvae feed on the upper level of leaves, near the main vein. In this study, digestive carbohydrases including α-glucosidase, β-glucosidase, α-galactosidase, β-galactosidase and proteinases including trypsin, chymotrypsin and elastase were investigated. The results showed that the carbohydrases were present in the alimentary tracts of the pest. Optimum pH for α-glucosidase and β-glucosidase activity was at pH 6.0 and 7.0, respectively. Maximum activity of α-galactosidase and β-galactosidase occurred at pH 6.0. Total proteolitic activity against the substrate azocasein was optimally occurred at pH 10.0. The greatest activity of trypsin, chymotrypsin and elastase was determined at pH 10.0, 11.0 and 11.0, respectively. Zymogram analyses using nitrocellulose membrane revealed two trypsin isoforms in which one of them was completely inhibited by Soybean Kunitz inhibitor and the other was notably inhibited. 相似文献

Due to pluripotency of induced pluripotent stem (iPS) cells, and the lack of immunological incompatibility and ethical issues, iPS cells have been considered as an invaluable cell source for future cell replacement therapy. This study was aimed first at establishment of novel iPS cells, ECiPS, which directly reprogrammed from human Eye Conjunctiva-derived Mesenchymal Stem Cells (EC-MSCs); second, comparing the inductive effects of Wnt3a/Activin A biomolecules to IDE1 small molecule in derivation of definitive endoderm (DE) from the ECiPS cells. To that end, first, the EC-MSCs were transduced by SOKM-expressing lentiviruses and characterized for endogenous expression of embryonic markers Then the established ECiPS cells were induced to DE formation by Wnt3a/Activin A or IDE1. Quantification of GSC, Sox17 and Foxa2 expression, as DE-specific markers, in both mRNA and protein levels revealed that induction of ECiPS cells by either Wnt3a/Activin A or IDE1 could enhance the expression level of the genes; however the levels of increase were higher in Wnt3a/Activin A induced ECiPS-EBs than IDE1 induced cells. Furthermore, the flow cytometry analyses showed no synergistic effect between Activin A and Wnt3a to derive DE-like cells from ECiPS cells. The comparative findings suggest that although both Wnt3a/Activin A signaling and IDE1 molecule could be used for differentiation of iPS into DE cells, the DE-inducing effect of Wnt3a/Activin A was statistically higher than IDE1. 相似文献

Background
Experimental evidence suggests that heat shock proteins (HSP) and asymmetric dimethylarginine (ADMA) are induced in the state of chronic inflammation and stress conditions. They are both inhibitors of nitric oxide synthase (NOS). The aim of this study was to evaluate the correlation between ADMA and HSP70, in patients with type 2 diabetes with respect to serum levels of C reactive protein (CRP).Methods
We quantified serum HSP70, ADMA and CRP in 80 newly-diagnosed patients with type 2 diabetes plus 80 age-, sex and BMI-matched healthy controls. The patients and controls were also stratified into groups of high and low CRP levels (cut-point: 2.5 mg/ml).Results
Patients with type 2 diabetes had significantly higher serum HSP70 (0.52 [0.51–0.66] vs. 0.27 [0.26–0.36], p < 0.001), ADMA (0.86 [0.81–0.92] vs. 0.72 [0.71–0.85], p < 0.05) and CRP (2.9 [1.7–3.4] vs. 1.6[1.2–2.3], p < 0.05) compared with healthy controls. Serum HSP70 and ADMA levels were significantly correlated in patients with high CRP levels (r = 0.89, p < 0.01), whereas there were no correlation in patients with low CRP (r = − 0.37, p = 0.07) and controls. This correlation was significant (r = 0.77, p < 0.001) in patients with high CRP and also in patients with low CRP levels (r = − 0.51, p < 0.05), after multiple adjustments for LDL and HDL levels.Discussion
We showed that, in a state of high inflammation; serum levels of ADMA parallel the HSP70 levels. However in low inflammation, they are negatively correlated. The duality in HSP70 and ADMA correlation may be related to the duality of NOS function in low and high CRP levels. 相似文献9.

HSV-1 infection of the cornea leads to a potentially blinding immunoinflammatory lesion of the cornea, termed herpetic stromal keratitis. It has also been shown that one of the factors limiting inflammation of the cornea is the presence of Fas ligand (FasL) on corneal epithelium and endothelium. In this study, the role played by FasL expression in the cornea following acute infection with HSV-1 was determined. Both BALB/c and C57BL/6 (B6) mice with HSV-1 infection were compared with their lpr and gld counterparts. Results indicated that mice bearing mutations in the Fas Ag (lpr) displayed the most severe disease, whereas the FasL-defective gld mouse displayed an intermediate phenotype. It was further demonstrated that increased disease was due to lack of Fas expression on bone marrow-derived cells. Of interest, although virus persisted slightly longer in the corneas of mice bearing lpr and gld mutations, the persistence of infectious virus in the trigeminal ganglia was the same for all strains infected. Further, B6 mice bearing lpr and gld mutations were also more resistant to virus-induced mortality than were wild-type B6 mice. Thus, neither disease nor mortality correlated with viral replication in these mice. Collectively, the findings indicate that the presence of FasL on the cornea restricts the entry of Fas(+) bone marrow-derived inflammatory cells and thus reduces the severity of HSK. 相似文献

3, 5, 6-Trichloro-2-pyridinol (TCP) is a stable metabolite of two major pesticides, Chlopyrifos insecticide and Triclopyr herbicide, which are widely used in the world. The potential health hazard associated with TCP is identified due to its high affinity to the DNA molecule. Therefore, in this study, the interaction of native calf thymus DNA with TCP has been investigated using spectrophotometric, circular dichroism (CD), spectrofluorometric, viscometric and voltametric techniques. It was found that TCP molecules could interact with DNA via a groove-binding mode, as evidenced by hyperchromism, with no red shift in the UV absorption band of TCP, no changes in K(b) values in the presence of salt, no significant changes in the specific viscosity and CD spectra of DNA, and a decrease in peak currents with no shift in the voltamogram. In addition, TCP is able to release Hoechst 33258, a strong groove binder, in the DNA solutions. The results are indicative of the groove-binding mode of TCP to DNA. 相似文献
