Interpretation of correlations between coagulation factors FV, FVIII and vWF in normal and type 2 diabetes mellitus patients     

Dayer MR  Mard-Soltani M  Dayer MS  Alavi SM 《Pakistan journal of biological sciences: PJBS》2011,14(9):552-557

Increased risk of vascular diseases in hypercoagulable states is assumed to be the major cause for prevalence of vascular problems in type 2 diabetes mellitus patient. The present study was undertaken to explore the basis underlying the correlation between the aforesaid three coagulation factors with reference to the relevant mechanistic findings using statistical calculation. Our findings showed that the correlation between each pairs of coagulation factors, FV, FVIII and vWF could be easily interpreted using previously characterized interactions between these factors. Also, given the sequence similarities between FV and FVIII as well as the results of this study, it was indicated, for the first time, that FV may bind to vWF in the same way as FVIII binds. This finding seems to be of great importance to be evaluated through experimental techniques.  相似文献

Traumatic Brain Injury Has Not Prominent Effects on Cardiopulmonary Indices of Rat after 24 Hours: Hemodynamic,Histopathology, and Biochemical Evidence     

Hamid Najafipour  Ali Siahposht Khachaki  Mohammad Khaksari  Beydolah Shahouzehi  Siyavash Joukar  Hamid Reza Poursalehi 《Iranian Biomedical Journal》2014,18(4):225-231

Background: Accidents are the second reason for mortality and morbidity in Iran. Among them, brain injuries are the most important damage. Clarification of the effects of brain injuries on different body systems will help physicians to prioritize their treatment strategies. In this study, the effect of pure brain trauma on the cardiovascular system and lungs 24 hours post trauma was assessed. Methods: Male Wistar rats (n = 32) were divided into sham control and traumatic brain injury (TBI) groups. In TBI animals, under deep anesthesia, a blow to the head was induced by the fall of a 450 g weight from 2 m height. Twenty four hours later, heart electrocardiogram and functional indices, cardiac troponin I, IL-6, TNF-, IL-Iβ in tissue and serum, and the histopathology of heart and lung were assessed. Results: The results showed that none of the functional, biochemical, inflammatory, and histopathology indices was statistically different between the two groups at 24 hours post TBI. Indices of impulse conduction velocity in atrium (P wave duration and P-R interval) were significantly longer in the TBI group. Conclusion: Overall, no important functional and histopathologic disturbances were found in heart and lung of TBI group after 24 hours. If the data is reproduced in human studies, the medical team could allocate their priority to treatment of brain disorders of the victim in the first 24 hours of pure TBI and postpone extensive assessment of heart and lung health indices to later time, thus reducing patient and health system expenditures.

Preparation and properties of crosslinkable waterborne polyurethanes containing aminoplast     

Ji Yun Kwon  Mohammad Mizanur Rahman  Han Do Kim 《Fibers and Polymers》2006,7(2):95-104

In order to improve the water swelling, thermal/mechanical and adhesion properties of waterborne polyurethane (WBPU), a series of the crosslinkable WBPUs containing hydrophilic ionic component, dimethylol propionic acid (20 mole%), were prepared by in-situ polymerization using a cross-linker hexakis (methoxymethyl) melamine (HMMM). Effects of the HMMM content (2, 4, and 6 wt%) and curing temperature on these properties of the crosslinked WBPUs samples were investigated. All properties were found to increase with increasing HMMM content. It was found that the optimum curing temperature of the WBPU films and adhesives was near 120°C, which was not dependent on the HMMM content.  相似文献

Anthelmintic and antimicrobial activity of methanolic and aqueous extracts of Euphorbia helioscopia L.     

Bashir A. Lone  Suhaib A. Bandh  Mohammad Zahoor Chishti  Fayaz Ahmad Bhat  Hidayatullah Tak  Humeera Nisa 《Tropical animal health and production》2013,45(3):743-749

The aim of this study was to evaluate the anthelmintic and antimicrobial efficacy of Euphorbia helioscopia crude extracts. A worm motility inhibition assay and egg hatch assay were used for in vitro study, and a faecal egg count reduction assay was used for in vivo study. The in vitro study revealed anthelmintic effects of crude methanolic extracts of E. helioscopia on live Haemonchus contortus worms as evident from their paralysis and/or death at 8 h after exposure. Different concentrations (12.5 mg?ml^?1, 25 mg?ml^?1 and 50 mg?ml^?1) of aqueous and methanolic extracts were used against H. contortus which exhibited dose-dependent anthelmintic effects on H. contortus. Different extracts of E. helioscopia on percent inhibitory egg hatching was very low as compared to levamisole. The antimicrobial activity of extracts ranging from 100 to 500 mg?ml^?1 screened by disc diffusion method against four selected bacterial (Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas multocida and Escherichia coli) and two fungal strains (Aspergillus flavus and Candida albicans) was also dose dependent with the extract showing more inhibitory effects against S. aureus and E. coli and a minimum inhibitory effect against A. flavus. It is concluded that the entire plant of E. helioscopia possesses significant anthelmintic and antimicrobial activity and could be a potential alternative for treating cases of helminth infections in ruminants.  相似文献   

Prevalence, molecular diagnosis and treatment of Mycoplasma conjunctivae isolated from infectious keratoconjunctivitis affected Lohi sheep maintained at Livestock Experiment Station, Bahadurnagar, Okara, Pakistan

Mycoplasma conjunctivae are etiological agents of infectious keratoconjunctivitis (IKC), commonly known as pink-eye in domestic sheep, goats and other wild animals in many parts of the world. A few young Lohi lambs maintained at Livestock Experiment Station (LES), Bahadurnagar, Okara, Pakistan showed clinical signs and symptoms of conjunctivitis, keratitis, severe lacrimation and varying degree of blindness. During January to March, 2011, a total of 36 ocular swabs were collected from IKC affected animals and were processed for isolation, identification, and characterization of M. conjunctivae. Sixteen (44.44 %) out of 36 samples showed turbidity in PPLO broth. Twelve (75 %) out of 16 broth samples showed colony growth on PPLO agar. All 16 (44.44 %) out of 36 turbid broth samples, 12 (75 %) out of 16 cultured on agar plate samples, and 21 (59 %) out of 36 sheep ocular direct swab samples were found positive for M. conjunctivae through polymerase chain reaction test by using M. conjunctivae-specific primer pair McoF1 and McoR1 and detecting a 750 base pair fragment on agarose gel. Topical application of 0.5 % sterile solution of gentamycin (100 mg/ml) (Gentafar 10 %, FARVET, Netherlands) proved suitable for the treatment of IKC in Lohi lambs as all clinical signs of IKC disappeared after 5 days of treatment with this antibiotic. This is the first report about the prevalence, molecular diagnosis, and treatment of M. conjunctivae in Lohi sheep affected with infectious keratoconjunctivitis at LES, Bahadurnagar, Okara, Pakistan.  相似文献   

The population structure of Salmonella enterica Enteritidis in Iran analyzed by multiple-locus variable-number tandem repeat analysis

Salmonella enterica Enteritidis is the most frequent etiological agent of salmonellosis in humans and poultry. To understand the genetic diversity of S. Enteritidis in Iran, we examined 69 chicken isolates from 18 broiler farms and six non-epidemic human isolates from six geographically distant provinces by multi-locus variable-number tandem repeat analysis (MLVA). Among SE2, SE3, SE5, SE7, SE8, SENTR4, and SENTR7, only SE5 with four and SENTR7 with two alleles, respectively, proved variable giving estimates of locus genetic diversity of 0.58 and 0. In all, six closely related MLVA profiles were identified among which three were commonly represented by human and chicken isolates. This population homogeneity contrasts with the high diversity at these loci reported elsewhere and is likely a consequence of a single clone of S. Enteritidis distributed across Iran.  相似文献   

Interactive Effect of GA3, N and P Ameliorate Growth,Seed and Fibre Yield by Enhancing Photosynthetic Capacity and Carbonic Anhydrase Activity of Linseed: A Dual Purpose Crop     

Mohammad N. Khan  Firoz Mohammad 《农业科学学报》2013,12(7):1183-1194

Linseed (Linum usitatissimum L.) is an important dual-purpose, industrial crop. Its seeds are used for the extraction of oil and stem for fibres. However, the production of linseed is not going parallel with the increasing demand of its products. The present work was carried out with an aim to find out whether exogenous application of gibberellic acid (GA₃) with or without graded levels of nitrogen (N) and phosphorus (P) could improve the performance of three linseed genotypes Parvati, Shekhar and Shubhra together with minimizing the costly fertilizer input and losses. Four combinations of N and P, viz., 0 mg N+0 mg P kg^?1 soil (N₀P₀), N_13.4P_4.46, N_26.8P_8.94 and N_40.2P_13.4 were constituted. Half dose of each combination was applied basally at the time of sowing and remaining half dose was given at 40 d after sowing (DAS) as foliar spray along with 10^?6 mol L^?1 GA₃. Prior to sowing, the seeds of each linseed genotype were grouped in to two, one group of seeds was soaked in 0 mol L^?1 GA₃ (control) and the other group was soaked in 10^?6 M GA₃ solution, each for 8 hours. Treatments were comprised of (i) 0 mol L^?1 GA₃+N₀P₀ (T₀, control), (ii) 10^?6 mol L^?1 GA₃ + N₁₃₄P₄₄₆ (T₁), (iii) 10^?6 mol L^?1 GA₃+N_26.8P_8.94 (T₂) and (iv) 10^?6 mol L^?1 GA₃+N_40.2P_13.4 (T₃). The crop performance was assessed in terms of growth, physiological and biochemical parameters at 60 and 75 DAS and yield attributes at harvest (175 DAS). The results showed a parallel increase in most of the parameters with increasing levels of N and P. However, application of 10^?6 mol L^?1 GA₃ in association with N_26.8P_8.94 proved best, it enhanced seed yield, oil yield and fibre yield by 83.3, 97.3 and 78.7%, respectively accompanied with increase in net photosynthetic rate, carbonic anhydrase activity and dry matter accumulation. Among the genotypes tested, Shubhra performed best, while Parvati the least for most of the parameters studied. Thus, combined application of 10^?6 mol L^?1 GA₃ plus N_26.8P_8.94 proved best and can be recommended to exploit the linseed as a dual-purpose crop for good yield of seed and fibre.  相似文献
