    Three prothrombin activators; ecarin, which was originally isolated from the venom of the saw-scaled viper Echis carinatus, trocarin from the rough-scaled snake Tropidechis carinatus, and oscutarin from the Taipan snake Oxyuranus scutellatus, were expressed in mammalian cells with the purpose to obtain recombinant prothrombin activators that could be used to convert prothrombin to thrombin. We have previously reported that recombinant ecarin can efficiently generate thrombin without the need ...

    We have produced data and developed analysis to build representations for the concentration of spores of nonproteolytic Clostridium botulinum in materials that are used during the manufacture of minimally processed chilled foods in the United Kingdom. Food materials are categorized into homogenous groups which include meat, fish, shellfish, cereals, fresh plant material, dairy liquid, dairy nonliquid, mushroom and fungi, and dried herbs and spices. Models are constructed in a Bayesian framework and represent a combination of information from a literature survey of spore loads from positive-control experiments that establish a detection limit and from dedicated microbiological tests for real food materials. The detection of nonproteolytic C. botulinum employed an optimized protocol that combines selective enrichment culture with multiplex PCR, and the majority of tests on food materials were negative. Posterior beliefs about spore loads center on a concentration range of 1 to 10 spores kg(-1). Posterior beliefs for larger spore loads were most significant for dried herbs and spices and were most sensitive to the detailed results from control experiments. Probability distributions for spore loads are represented in a convenient form that can be used for numerical analysis and risk assessments. Copyright © 2016 Barker et al.

    Dr. De Teresa and others reported that mean prothrombin time ratio of 12 patients on long-term anticoagulation with warfarin was significantly higher when they were also taking oral contraceptives (OCs). A study of prothrombin complex activity was recently conducted in female rats treated with an estrogen-progestogen combination (lynestrenol 5 mg; mestranol 0.3 mg/kg body weight) which resulted in a 100% infertility in this species. After 1 treatment for only 1 estral cycle, OC-treated rats had a significantly longer Normotest clotting time (37.7+ or-0.5 sec) than control rats (31.0+or-0.4); the difference was even more notable after 10 cycles. Although this finding has not been reported in women on OCs, it may be that the estrogen-induced "lability" of the prothrombin complex occurs in humans only in special conditions, such as anticoagulation. Alternatively, liver dysfunction occurring among women on OCs may be responsible for reduced metabolism of warfarin, contributing to the effectiveness of the anticoagulation. Further pharmacology studies should be done to clarify the interaction between OCs and oral anticoagulants.

    1996-01-01

    Seven strains of nonproteolytic Clostridium botulinum (types B, E, and F) were each inoculated into a range of anaerobic cooked puréed vegetables. After incubation at 10 degrees C for 15 to 60 days, all seven strains formed toxin in mushrooms, five did so in broccoli, four did so in cauliflower, three did so in asparagus, and one did so in kale. Growth kinetics of nonproteolytic C. botulinum type B in cooked mushrooms, cauliflower, and potatoes were determined at 16, 10, 8, and 5 degrees C. Growth and toxin production occurred in cooked cauliflower and mushrooms at all temperatures and in potatoes at 16 and 8 degrees C. The C. botulinum neurotoxin was detected within 3 to 5 days at 16 degrees C, 11 to 13 days at 10 degrees C, 10 to 34 days at 8 degrees C, and 17 to 20 days at 5 degrees C. PMID:8702303

    The highly potent botulinum neurotoxins are responsible for botulism, a severe neuroparalytic disease. Strains of nonproteolytic Clostridium botulinum form neurotoxins of types B, E, and F and are the main hazard associated with minimally heated refrigerated foods. Recent developments in quantitative microbiological risk assessment (QMRA) and food safety objectives (FSO) have made food safety more quantitative and include, as inputs, probability distributions for the contamination of food materials and foods. A new method that combines a selective enrichment culture with multiplex PCR has been developed and validated to enumerate specifically the spores of nonproteolytic C. botulinum. Key features of this new method include the following: (i) it is specific for nonproteolytic C. botulinum (and does not detect proteolytic C. botulinum), (ii) the detection limit has been determined for each food tested (using carefully structured control samples), and (iii) a low detection limit has been achieved by the use of selective enrichment and large test samples. The method has been used to enumerate spores of nonproteolytic C. botulinum in 637 samples of 19 food materials included in pasta-based minimally heated refrigerated foods and in 7 complete foods. A total of 32 samples (5 egg pastas and 27 scallops) contained spores of nonproteolytic C. botulinum type B or F. The majority of samples contained <100 spores/kg, but one sample of scallops contained 444 spores/kg. Nonproteolytic C. botulinum type E was not detected. Importantly, for QMRA and FSO, the construction of probability distributions will enable the frequency of packs containing particular levels of contamination to be determined.

    Fibrinogen and prothrombin have been suggested to become rate limiting in trauma associated coagulopathy. Administration of fibrinogen is now recommended, however, the importance of prothrombin to patient outcome is unknown. We have utilized two trauma patient databases (database 1 n = 358 and database 2 n = 331) to investigate the relationship of plasma prothrombin concentration on clinical outcome and coagulation status. Database 1 has been used to assess the relationship of plasma prothrombin to administered packed red blood cells (PRBC), clinical outcome and coagulation biomarkers (Prothrombin Time (PT), ROTEM EXTEM Coagulation Time (CT) and Maximum Clot Firmness (MCF)). ROC analyses have been performed to investigate the ability of admission coagulation biomarkers to predict low prothrombin concentration (database 1), massive transfusion and 24 h mortality (database 1 and 2). The importance of prothrombin was further investigated in vitro by PT and ROTEM assays in the presence of a prothrombin neutralizing monoclonal antibody and following step-wise dilution. Patients who survived the first 24 h had higher admission prothrombin levels compared to those who died (94 vs.67 IU/dL). Patients with lower transfusion requirements within the first 24 h (≤10 units of PRBCs) also had higher admission prothrombin levels compared to patients with massive transfusion demands (>10 units of PRBCs) (95 vs.62 IU/dL). Admission PT, in comparison to admission ROTEM EXTEM CT and MCF, was found to be a better predictor of prothrombin concentration <60 IU/dL (AUC 0.94 in database 1), of massive transfusion (AUC 0.92 and 0.81 in database 1 and 2 respectively) and 24 h mortality (AUC 0.90 and 0.78 in database 1 and 2, respectively). In vitro experiments supported a critical role for prothrombin in coagulation and demonstrated that PT and ROTEM EXTEM CT are sensitive methods to measure low prothrombin concentration. Our analyses suggest that prothrombin concentration

    The UniProt knowledgebase, UniProtKB, is the main product of the UniProt consortium. It consists of two sections, UniProtKB/Swiss-Prot, the manually curated section, and UniProtKB/TrEMBL, the computer translation of the EMBL/GenBank/DDBJ nucleotide sequence database. Taken together, these two sections cover all the proteins characterized or inferred from all publicly available nucleotide sequences. The Plant Proteome Annotation Program (PPAP) of UniProtKB/Swiss-Prot focuses on the manual annotation of plant-specific proteins and protein families. Our major effort is currently directed towards the two model plants Arabidopsis thaliana and Oryza sativa. In UniProtKB/Swiss-Prot, redundancy is minimized by merging all data from different sources in a single entry. The proposed protein sequence is frequently modified after comparison with ESTs, full length transcripts or homologous proteins from other species. The information present in manually curated entries allows the reconstruction of all described isoforms. The annotation also includes proteomics data such as PTM and protein identification MS experimental results. UniProtKB and the other products of the UniProt consortium are accessible online at www.uniprot.org.

    Women with antiphospholipid antibodies (aPL) such as lupus anticoagulant, anticardiolipin antibodies, and anti-β(2) glycoprotein-1 antibodies are at high risk of late pregnancy complications, such as severe pre-eclampsia, placental insufficiency, and fetal loss. It has been observed that aPL consists of a heterogeneous group of antibodies targeting several phospholipid-binding plasma proteins, including also anti-prothrombin (anti-PT), anti-protein S (anti-PS), and anti-protein C (anti-PC) antibodies. Their potential role in late pregnancy complications is not known. The aim of this work was to investigate the association between those autoantibodies and histories for adverse pregnancy outcome. Anti-PT, anti-PS, and anti-PC antibodies were evaluated in 163 patients with previous severe pre-eclampsia, fetal death, and/or placental abruption and in as many women with previous uneventful pregnancies, negative for aPL. The prevalence of anti-PT antibodies was higher in cases than in controls (OR, 95% CI: 10.92, 4.52-26.38). The highest prevalence was observed in subjects with fetal death. Anti-PT antibodies appear to be associated with adverse pregnancy outcome, irrespectively of aPL. © 2011 John Wiley & Sons A/S.

  20. Decreased prothrombin conversion and reduced thrombin inactivation explain rebalanced thrombin generation in liver cirrhosis.

    Directory of Open Access Journals (Sweden)

    Romy M W Kremers

    Full Text Available Impaired coagulation factor synthesis in cirrhosis causes a reduction of most pro- and anticoagulant factors. Cirrhosis patients show no clear bleeding or thrombotic phenotype, although they are at risk for both types of hemostatic event. Thrombin generation (TG is a global coagulation test and its outcome depends on underlying pro- and anticoagulant processes (prothrombin conversion and thrombin inactivation. We quantified the prothrombin conversion and thrombin inactivation during TG in 30 healthy subjects and 52 Child-Pugh (CP- A, 15 CP-B and 6 CP-C cirrhosis patients to test the hypothesis that coagulation is rebalanced in liver cirrhosis patients. Both prothrombin conversion and thrombin inactivation are reduced in cirrhosis patients. The effect on pro- and anticoagulant processes partially cancel each other out and as a result TG is comparable at 5 pM tissue factor between healthy subjects and patients. This supports the hypothesis of rebalanced hemostasis, as TG in cirrhosis patients remains within the normal range, despite large changes in prothrombin conversion and thrombin inactivation. Nevertheless, in silico analysis shows that normalization of either prothrombin conversion or thrombin inactivation to physiological levels, by for example the administration of prothrombin complex concentrates would cause an elevation of TG, whereas the normalization of both simultaneously maintains a balanced TG. Therefore, cirrhosis patients might require adapted hemostatic treatment.

    Low immunogenicity and high repopulation capacity are crucial determinants for the functional and structural performance of acellular cardiovascular implants. The present study evaluates a detergent-free, non-proteolytic, actin-disassembling regimen (BIO) for decellularization of heart valve and vessel grafts, particularly focusing on their bio-functionality. Rat aortic conduits (rAoC; n = 89) and porcine aortic valve samples (n = 106) are decellularized using detergents (group DET) or the BIO regimen. BIO decellularization results in effective elimination of cellular proteins and significantly improves removal of DNA as compared with group DET, while the extracellular matrix (ECM) structure as well as mechanical properties are preserved. The architecture of rAoC in group BIO allows for improved bio-functionalization with fibronectin (FN) in a standardized rat implantation model: BIO treatment significantly increases speed and amount of autologous medial cellular repopulation in vivo (p < 0.001) and decreases the formation of hyperplastic intima (p < 0.001) as compared with FN-coated DET-decellularized grafts. Moreover, there are no signs of infiltration with inflammatory cells. The present biological, detergent-free, non-proteolytic regimen balances effective decellularization and ECM preservation in cardiovascular grafts, and provides optimized bio-functionality. Additionally, this study implies that the actin-disassembling regimen may be a promising approach for bioengineering of acellular scaffolds from other muscular tissues, as for example myocardium or intestine.

    Antibodies to prothrombin are detected by directly coating prothrombin on irradiated ELISA plates (aPT) or by using the phosphatidylserine/prothrombin complex as antigen (aPS/PT). Although these antibodies have both been associated with antiphospholipid syndrome (APS) and a correlation between the two assays have been reported, it seems that aPT and aPS/PT belong to different populations of autoantibodies. It was our objective to systematically review the available evidence on aPT and aPS/PT antibodies and the risk of thrombosis in APS. Medline-reports published between 1988 and 2013 investigating aPT and aPS/PT as a risk factor for thrombosis were included. Whenever possible, antibody isotype(s) and site of thrombosis were analysed. This systematic review is based on available data from more than 7,000 patients and controls from 38 studies analysing aPT and 10 aPS/PT. Antibodies to prothrombin (both aPT and aPS/PT) increased the risk of thrombosis (odds ratio [OR] 2.3; 95% confidence interval [CI] 1.72-3.5). aPS/PT seemed to represent a stronger risk factor for thrombosis, both arterial and/or venous than aPT (OR 5.11; 95%CI 4.2-6.3 and OR 1.82; 95%CI 1.44-2.75, respectively). In conclusion, routine measurement of aPS/PT (but not aPT) might be useful in establishing the thrombotic risk of patients with previous thrombosis and/or systemic lupus erythematosus. Their inclusion as laboratory criteria for the APS should be indisputably further explored.

  5. Automatically extracting functionally equivalent proteins from SwissProt

    Directory of Open Access Journals (Sweden)

    Martin Andrew CR

    2008-10-01

    Full Text Available Abstract Background There is a frequent need to obtain sets of functionally equivalent homologous proteins (FEPs from different species. While it is usually the case that orthology implies functional equivalence, this is not always true; therefore datasets of orthologous proteins are not appropriate. The information relevant to extracting FEPs is contained in databanks such as UniProtKB/Swiss-Prot and a manual analysis of these data allow FEPs to be extracted on a one-off basis. However there has been no resource allowing the easy, automatic extraction of groups of FEPs – for example, all instances of protein C. We have developed FOSTA, an automatically generated database of FEPs annotated as having the same function in UniProtKB/Swiss-Prot which can be used for large-scale analysis. The method builds a candidate list of homologues and filters out functionally diverged proteins on the basis of functional annotations using a simple text mining approach. Results Large scale evaluation of our FEP extraction method is difficult as there is no gold-standard dataset against which the method can be benchmarked. However, a manual analysis of five protein families confirmed a high level of performance. A more extensive comparison with two manually verified functional equivalence datasets also demonstrated very good performance. Conclusion In summary, FOSTA provides an automated analysis of annotations in UniProtKB/Swiss-Prot to enable groups of proteins already annotated as functionally equivalent, to be extracted. Our results demonstrate that the vast majority of UniProtKB/Swiss-Prot functional annotations are of high quality, and that FOSTA can interpret annotations successfully. Where FOSTA is not successful, we are able to highlight inconsistencies in UniProtKB/Swiss-Prot annotation. Most of these would have presented equal difficulties for manual interpretation of annotations. We discuss limitations and possible future extensions to FOSTA, and

  10. Toxin production of non-proteolytic Cl. botulinum type B in radurized fish. Part of a coordinated programme on the wholesomeness of the process of food irradiation

    1981-02-01

    Toxin formation by proteolytic and nonproteolytic strains of C. botulinum type B in radurized raw fish and in radurized Pindang fish was investigated. In radurized Pindang fish samples, inoculation was done either before or after cooking. Radurization process with 2 and 3 kGy caused the extension of storage life of Rastrelliger sp., Euthynnus sp., and Scomberomorus sp. by factors of 2 and 2.5 at storage temperatures between 5 and 10 0 C. In general at 10.5 +- 0.3 0 C, no toxin was formed before the samples were spoiled both in irradiated and unirradiated samples. At 5.6 +- 0.5 0 C no toxin was formed until after the samples were spoiled. The earliest toxin formation in unirradiated Pindang samples stored at ambient temperature was detected after the samples were spoiled. In irradiated Pindang samples inoculated with C. botulinum spores after cooking and stored at ambient temperature the toxin formation was detected before the samples were spoiled. However, if the inoculation was done before the fish was processed into Pindang, the toxin was always detected after the samples were spoiled regardless of the irradiation dose, strain and inoculation level. As fish may be contaminated - if at all - with spores of C. botulinum in its raw state, processing of fish into Pindang and irradiation would not contribute to the health hazard concerning botulism even if the samples are stored at ambient temperature

    The effect of three different concentrations of sodium nitrite (0, 75, and 120 mg/kg) on growth and toxigenesis of group II (nonproteolytic) Clostridium botulinum type B was studied in Finnish wiener-type sausage, bologna-type sausage, and cooked ham. A low level of inoculum (2.0 log CFU/g) was used for wiener-type sausage and bologna-type sausage, and both low (2.0 log CFU/g) and high (4.0 log CFU/g) levels were used for cooked ham. The products were formulated and processed under simulated commercial conditions and stored at 8°C for 5 weeks. C. botulinum counts were determined in five replicate samples of each nitrite concentration at 1, 3, and 5 weeks after thermal processing. All samples were positive for C. botulinum type B. The highest C. botulinum counts were detected in nitrite-free products. Toxigenesis was observed in nitrite-free products during storage, but products containing either 75 or 120 mg/kg nitrite remained nontoxic during the 5-week study period, suggesting that spores surviving the heat treatment were unable to germinate and develop into a toxic culture in the presence of nitrite. The results suggest that the safety of processed meat products with respect to group II C. botulinum type B can be maintained even with a reduced concentration (75 mg/kg) of sodium nitrite.

    Antibodies to prothrombin in solid phase (aPT) and those to phosphatidiyserine-prothrombin complex (aPS/PT) have been suggested to strongly correlate with the presence of lupus anticoagulant (LA). As their clinical diagnostic value and true relationship with the LA remains elusive, we designed this study to evaluate the prevalence and significance of aPT and aPS/PT in a large cohort of patients with and without LA. Samples from 257 patients were included. aPT and aPS/PT were tested by ELISA. LA was tested as per the current criteria from the ISTH Subcommittee on LA-Phospholipid-dependent antibodies. aPS/PT and aPT were found in 51% and 32% of LA-positive (LA+ve) patients and in 22% and 28% of LA-negative (LA-ve) patients, respectively. Thrombosis, particularly venous thrombosis was associated with IgG aPT in the LA+ve group (p=0.0006) and in the LA-ve group (p=0.017). Antibodies to phosphatidylserine-prothrombin, either IgG and IgM were associated with thrombosis in general (p=0.0003) in particularly with venous thrombosis in the LA+ve group (paPS/PT were independent risk factors for thrombosis and pregnancy loss. In conclusion, aPS/PT, but not aPT, are more frequently found in patients with LA. Their association with thrombosis seems to be independent of the presence of LA.

    Factor VII (FVII) deficiency is one of the two congenital coagulation disorders that was not discovered by the description of a new bleeding patient whose clotting pattern did not fit the blood coagulation knowledge of the time (the other is factor XIII deficiency). The existence of an additional factor capable of accelerating the conversion of prothrombin into thrombin was suspected before 1951, the year in which the first family with FVII deficiency was discovered. As several investigators were involved in the discovery of FVII deficiency from both sides of the Atlantic, several different names were tentatively suggested to define this entity, namely stable factor (in contrast with labile factor or FV), cothromboplastin, proconvertin, serum prothrombin conversion accelerator, prothrombin acceleration, and autoprothrombin I. The last term was proposed by those who denied the existence of this new entity, which was instead considered to be a derivate of prothrombin activation, namely autoprothrombin. The description of several families, from all over the world, of the same defect, however clearly demonstrated the singularity of the condition. Factor VII was then proposed to define this protein. In subsequent years, several variants were described with peculiar reactivity toward tissue thromboplastins of different origin. Molecular biology techniques demonstrated several gene mutations, usually missense mutations, often involving exon 8 of the FVII gene. Later studies dealt with the relation of FVII with tissue factor and activated FVII (FVIIa). The evaluation of circulating FVIIa was made possible by the use of a truncated form of tissue factor, which is only sensitive to FVIIa present in the circulation. The development of FVII concentrates, both plasma derived and recombinant, has facilitated therapeutic management of FVII-deficient patients. The use of FVIIa concentrates was noted to be associated with the occasional occurrence of thrombotic events, mainly

In addition, the extrinsic coagulation pathway was monitored with the clotting activity of single...... factors II, VII, and X. No effect on the intrinsic coagulation pathway was observed. There was a significant and rapid decrease in prothrombin time. Coagulation factors II, VII and X, the three components of prothrombin time, decreased significantly to different degrees. We conclude that infusion of N...

    Protein complex-based feature selection (PCBFS) provides unparalleled reproducibility with high phenotypic relevance on proteomics data. Currently, there are five PCBFS paradigms, but not all representative methods have been implemented or made readily available. To allow general users to take advantage of these methods, we developed the R-package NetProt, which provides implementations of representative feature-selection methods. NetProt also provides methods for generating simulated differential data and generating pseudocomplexes for complex-based performance benchmarking. The NetProt open source R package is available for download from https://github.com/gohwils/NetProt/releases/ , and online documentation is available at http://rpubs.com/gohwils/204259 .

    Antiprothrombin antibodies can be measured by ELISA using either a prothrombin/phosphatidylserine complex (aPS/PT) or prothrombin alone (aPT) as antigen. We aimed to compare the clinical features of autoimmune patients with avidity of aPS/PT and determine the diagnostic efficiency of aPS/PT and aPT for assessing antiphospholipid syndrome (APS). aPS/PT were of low (n = 9), heterogeneous (n = 31) and high (n = 8) avidity out of 48 cases. None of the samples with low avidity were positive in aPT ELISA. Among patients with heterogeneous or high avidity aPS/PT, there was a significantly greater number of patients with APS as compared to patients with low avidity (38/39 vs. 7/9; p < 0.05). No SLE patients had high avidity antiprothrombin antibodies.

    We have recently reported that increased levels of urine prothrombin fragment 1+2 reflected radiologically verified deep vein thrombosis. In this study we evaluated whether urine prothrombin fragment 1+2 was associated with pulmonary embolism in non-selected patients. Patients with clinical suspected pulmonary embolism were interviewed on comorbidities and medications. Urine was collected from each patient before radiological examination and snap frozen until analysed on urine prothrombin fragment 1+2 with an ELISA kit. Imaging of the pulmonary arteries were conducted with contrast enhanced computer tomography. Pulmonary embolism was diagnosed in 44/197 patients. Non-significantly higher urine prothrombin fragment 1+2 levels were found in non-selected patients with pulmonary embolism vs. those without (p=0.324). Significantly higher urine prothrombin fragment 1+2 levels were found in the pulmonary embolism positive patients without comorbidities (n=13) compared to the control group (n=28) (p=0.009). The calculated sensitivity, specificity and negative predictive value using the lowest detectable urine prothrombin fragment 1+2 level was 82%, 34% and 87%, respectively. There was no significant urine prothrombin fragment 1+2 level difference in patients with and without pulmonary embolism. In non-comorbide pulmonary embolism positive patients the urine prothrombin fragment 1+2 levels were significantly higher compared to the control group. The negative predictive value found in this study indicates that uF1+2 has the potential to identify patients with a low risk of PE. Copyright © 2014 Elsevier Ltd. All rights reserved.

    To determine the frequency of prothrombin G20210A gene mutation in pregnant females with adverse thrombotic obstetric complication and to compare it with prothrombin G20210A gene's frequency in control population. Study Design: Case control study. Place and Duration of Study: Department of Haematology, Army Medical College Rawalpindi and Military Hospital Rawalpindi, from Nov 2013 to Oct 2014. Material and Methods: Sixty pregnant females were included in the study; 30 were cases with adverse thrombotic obstetric complication, while 30 were controls. Detailed history was obtained and 3 ml blood in EDTA tube was collected. DNA was extracted from whole blood and through RT-PCR, presence of prothrombin G20210A gene mutation was looked for in patients and controls. Data was analyzed using SPSS 21. Results: A total of 60 women-30 cases with thrombotic obstetric complications as 'cases' and 30 as 'controls'- were included in the study. Mean age of 'cases' was 28.70 +- 4.23 years while that of 'controls' was 27.33 +- 4.49 years. There was no statistically significant difference among the two groups (p=0.54). In case group only one of 30 (3.3%) patients had heterozygous F2 G20210A mutation while 29 (96.7%) patients had wild type allele. In control group, all the 30 (100%) subjects had wild type allele. The odds of finding the mutation in cases was 1:29 i.e. 0.03 as compared to zero in the control group. The difference was statistically insignificant (p=0.5). Conclusion: Our study shows that the frequency of F2 G20210A gene mutation in pregnant females having adverse thrombotic obstetric complications was not significantly different from its frequency in control population.

    Herein we describe a case of microangiopathic antiphospholipid syndrome (MAPS) due to anti-phosphatidylserine/prothrombin complex (aPS/PT) IgM antibody successfully treated with rituximab. A significant correlation was observed between the clinical course and the aPS/PT IgM antibody titer, which can rise earlier before the appearance of clinical symptoms. Rituximab can be safely and effectively used for MAPS. Although detection of only aPS/PT IgM antibody is rare, aPS/PT IgM antibody might be associated with the pathogenesis of MAPS and might be a useful marker of disease activity. © 2017 Japan Pediatric Society.

    Direct oral anticoagulants (DOACs) pose a great challenge for physicians in life-threatening bleeding events. The aim of this study was to test the efficacy of reversing the DOAC rivaroxaban using four-factor PCC (prothrombin complex concentrate), a non-specific reversing agent. Patients with life-threatening bleeding events during rivaroxaban treatment were included and administered 25 U kg -1 of PCC. Blood samples were collected immediately prior to as well as after PCC treatment at predefined time intervals. The primary endpoint was defined as the difference in thrombin generation (TG) parameters ETP (endogenous thrombin potential) and C max (peak thrombin generation) prior to and ten minutes subsequent to PCC treatment. Thirteen patients, of whom the majority suffered from intra-cranial haemorrhage (ICH) or subdural haemorrhage (SDH), were included and administered PCC. The results show that the ETP (TG) significantly ( p  = 0.001) improved by 68% and C max (TG) by 54% (p = 0.001) during PCC treatment. In addition, the Quick value (prothrombin time: Quick PT ) significantly improved by 28% and the activated partial thromboplastin time (aPTT) was decreased by 7% ten minutes after PCC administration. C max was reduced at baseline, but not ETP, aPTT or Quick PT . Lag time until initiation (TG, t lag ), thromboelastometry clotting time (CT EXTEM ) and time to peak (TG, t max ) correlated best with measured rivaroxaban levels and were out of normal ranges at baseline, but did not improve after PCC administration. In 77% of the patients bleeding (ICH/SDH-progression) ceased following PCC administration. During the study three participants passed away due to other complications not related to PCC treatment. The possibility of thrombosis formation was also evaluated seven days after administering PCC and no thromboses were found. This study shows that use of PCC improved ETP, C max, Quick PT and aPTT. However, of these parameters, only C max was reduced at the

    The antiphospholipid antibodies present in antiphospholipid syndrome (APS) are directed at a number of phospholipid-binding proteins: β2 glycoprotein I (β2GPI), prothrombin, and so on. Antibodies directed at β2GPI are accepted as a classification criterion for APS, while the presence of antiprothrombin antibodies is not. In the present article, we investigated the possible role of antiphosphatidylserine/prothrombin antibodies (aPS/PT) as marker of APS on a cohort of 295 individuals with APS (95 primary APS and 45 secondary APS) and APS-related diseases. We found aPS/PT to be highly associated with venous thrombosis (immunoglobulin G [IgG] aPS/PT odds ratio [OR], 7.44; 95% confidence interval [CI], 3.97-13.92 and IgM aPS/PT OR, 2.54; 95% CI, 1.35-4.77) and obstetric abnormalities (IgG aPS/PT OR, 2.37; 95% CI, 1.04-5.43), but not with arterial thrombosis. A very high degree of concordance between the concentration of aPS/PT and lupus anticoagulant activity was demonstrated. Therefore, we support the inclusion of aPS/PT determination as second-level assay to confirm APS classification.

    2014-05-01

    Antiprothrombin antibodies have been proposed as potential new biomarkers for thrombosis and/or pregnancy morbidity in the setting of the antiphospholipid syndrome (APS). Antiprothrombin antibodies are commonly detected by ELISA, using prothrombin coated onto irradiated plates (aPT), or prothrombin in complex with phosphatidylserine (aPS/PT), as antigen. Although these antibodies can co-exist in the same patient, aPT and aPS/PT seem to belong to different populations of autoantibodies. Early research explored the role of antibodies to prothrombin as potential antigenic targets for the lupus anticoagulant (LA). To date their clinical significance is being investigated and their potential role in identifying patients at higher risk of developing thrombotic events or pregnancy morbidity is being probed.

    The Universal Protein Resource (UniProt) provides a central resource on protein sequences and functional annotation with three database components, each addressing a key need in protein bioinformatics. The UniProt Knowledgebase (UniProtKB), comprising the manually annotated UniProtKB/Swiss-Prot section and the automatically annotated UniProtKB/TrEMBL section, is the preeminent storehouse of protein annotation. The extensive cross-references, functional and feature annotations and literature-based evidence attribution enable scientists to analyse proteins and query across databases. The UniProt Reference Clusters (UniRef) speed similarity searches via sequence space compression by merging sequences that are 100% (UniRef100), 90% (UniRef90) or 50% (UniRef50) identical. Finally, the UniProt Archive (UniParc) stores all publicly available protein sequences, containing the history of sequence data with links to the source databases. UniProt databases continue to grow in size and in availability of information. Recent and upcoming changes to database contents, formats, controlled vocabularies and services are described. New download availability includes all major releases of UniProtKB, sequence collections by taxonomic division and complete proteomes. A bibliography mapping service has been added, and an ID mapping service will be available soon. UniProt databases can be accessed online at http://www.uniprot.org or downloaded at ftp://ftp.uniprot.org/pub/databases/.

We studied 34 prothrombin mutation heterozygous carriers and sex- and age-matched 34 non-carriers, all at least three months since the first VTE episode, before and during treatment with rivaroxaban. Clot permeability (K s ) and clot lysis time (CLT) with or without elimination of thrombin activatable fibrinolysis inhibitor (TAFI) were assessed at baseline, 2-6 hours (h) after and 20-25 h after intake of rivaroxaban (20 mg/day). At baseline, the prothrombin mutation group formed denser clots (K s -12 %, p=0.0006) and had impaired fibrinolysis (CLT +14 %, p=0.004, and CLT-TAFI +13 %, p=0.03) compared with the no mutation group and were similar to those observed in 15 healthy unrelated prothrombin mutation carriers. The G20210A prothrombin mutation was the independent predictor for K s and CLT before rivaroxaban intake. At 2-6 h after rivaroxaban intake, clot properties improved in both G20210A carriers and non-carriers (K s +38 %, and +37 %, CLT -25 % and -25 %, CLT-TAFI -20 % and -24 %, respectively, all pCLT +17 %, CLT-TAFI +13 %, all p<0.001). Rivaroxaban concentration correlated with fibrin clot properties. After 20-25 h since rivaroxaban intake most clot properties returned to baseline. Rivaroxaban-related differences in clot structure were confirmed by scanning electron microscopy images. In conclusion, rivaroxaban treatment, though improves fibrin clot properties, cannot abolish more prothrombotic fibrin clot phenotype observed in prothrombin mutation carriers following VTE.

  15. EST2Prot: Mapping EST sequences to proteins

    Directory of Open Access Journals (Sweden)

    Lin David M

    2006-03-01

    Full Text Available Abstract Background EST libraries are used in various biological studies, from microarray experiments to proteomic and genetic screens. These libraries usually contain many uncharacterized ESTs that are typically ignored since they cannot be mapped to known genes. Consequently, new discoveries are possibly overlooked. Results We describe a system (EST2Prot that uses multiple elements to map EST sequences to their corresponding protein products. EST2Prot uses UniGene clusters, substring analysis, information about protein coding regions in existing DNA sequences and protein database searches to detect protein products related to a query EST sequence. Gene Ontology terms, Swiss-Prot keywords, and protein similarity data are used to map the ESTs to functional descriptors. Conclusion EST2Prot extends and significantly enriches the popular UniGene mapping by utilizing multiple relations between known biological entities. It produces a mapping between ESTs and proteins in real-time through a simple web-interface. The system is part of the Biozon database and is accessible at http://biozon.org/tools/est/.

    2007-04-01

    Full Text Available Abstract Background Post-translational protein modification with ubiquitin, or ubiquitylation, is one of the hottest topics in a modern biology due to a dramatic impact on diverse metabolic pathways and involvement in pathogenesis of severe human diseases. A great number of eukaryotic proteins was found to be ubiquitylated. However, data about particular ubiquitylated proteins are rather disembodied. Description To fill a general need for collecting and systematizing experimental data concerning ubiquitylation we have developed a new resource, UbiProt Database, a knowledgebase of ubiquitylated proteins. The database contains retrievable information about overall characteristics of a particular protein, ubiquitylation features, related ubiquitylation and de-ubiquitylation machinery and literature references reflecting experimental evidence of ubiquitylation. UbiProt is available at http://ubiprot.org.ru for free. Conclusion UbiProt Database is a public resource offering comprehensive information on ubiquitylated proteins. The resource can serve as a general reference source both for researchers in ubiquitin field and those who deal with particular ubiquitylated proteins which are of their interest. Further development of the UbiProt Database is expected to be of common interest for research groups involved in studies of the ubiquitin system.

    A 25-year-old man presented with symptoms of syncope, cough, headache and hemoptysis. Cranial MR and venography showed thrombus formation in the right transverse sinus and superior sagittal sinus. Computed tomographic pulmonary angiography (CTPA) showed an embolic thrombus in the right pulmonary truncus and lung abscess. The patient was young, and there were no signs of lower extremity deep venous thrombosis or other major risk factors for pulmonary embolism (PE) including cardiac anomaly. The only risk factor we were able to identify was the presence of the prothrombin G20210A gene mutation. Anticoagulant treatment with oral warfarin (10 mg daily) and imipenem (4X500 mg) was started. The patient was hospitalized for antibiotic and anticoagulation therapies for three weeks and was discharged on lifelong treatment with warfarin (5 mg daily).

    In patients with hemophilia, prothrombin complex concentrates (PCCs) have been successfully used to bypass inhibitors to fctor VIII during bleeding episodes. The use of PCCS, including FEIBA (factor eight inhibitor bypassing activity), has been associated with thromboembolic complications. Myocardial infarction (MI) is a rare but serious complication, reported in 13 previous cases, six in the pediatric age group. In all four patients who died during the acute MI, autopsy revealed extensive myocardial hemorrhage. The hearts of three other patients examined at least 5 months after the acute MI showed no evidence of prior hemorrhage. Magnetic resonance (MR) imaging has been shown to be able to evaluate the sequelae of myocardial infarction in adults with coronary artery disease and in children with Kawasaki syndrome. We report the first case of the used of MR imaging in the evaluation of myocardial damage during the acute stage of a FEIBA-associated MI in a 10-year-old boy. (orig.)

    Anti-phosphatidylserine/prothrombin (aPS/PT) antibodies have begun to be considered potentional biomarkers for antiphospholipid syndrome (APS). This cohort study investigate the role of aPS/PT antibodies as a risk factor for severe APS by evaluating the association between those antibodies and clinical/laboratory profiles of APS. Plasma/serum samples from 197 APS patients, 100 healthy subjects and 106 patients with autoimmune diseases were collected. IgG/IgM aPS/PT antibodies were assayed using commercial ELISA kit. Prevalences of IgG and IgM aPS/PT (pantiphospholipid antibody patients than in double and single positivity ones (p<0.0001 for all). APS/PT antibodies were associated to severe thrombosis, severe pregnancy complications inducing prematurity, and vascular microangiopathy, all generally associated to high risk APS forms requiring strong therapy.

  1. Des-γ-Carboxy Prothrombin (DCP as a Potential Autologous Growth Factor for the Development of Hepatocellular Carcinoma

    Directory of Open Access Journals (Sweden)

    Yu-Sheng Zhang

    2014-08-01

    Full Text Available Des-γ-carboxy prothrombin (DCP is a prothrombin precursor produced in hepatocellular carcinoma (HCC. Because of deficiency of vitamin K or γ-glutamyl carboxylase in HCC cells, the 10 glutamic acid (Glu residues in prothrombin precursor did not completely carboxylate to γ-carboxylated glutamic acid (Gla residues, leaving some Glu residues remained in N-terminal domain. These prothrombin precursors with Glu residues are called DCPs. DCP displays insufficient coagulation activity. Since Liebman reported an elevated plasma DCP in patients with HCC, DCP has been used in the diagnosis of HCC. Recently, its biological malignant potential has been specified to describe DCP as an autologous growth factor to stimulate HCC growth and a paracrine factor to integrate HCC with vascular endothelial cells. DCP was found to stimulate HCC growth through activation of the DCP-Met-JAK1-STAT3 signaling pathway. DCP might increase HCC invasion and metastasis through activation of matrix metalloproteinase (MMPs and the ERK1/2 MAPK signaling pathway. DCP has also been found to play a crucial role in the formation of angiogenesis. DCP could increase the angiogenic factors released from HCC and vascular endothelial cells. These effects of DCP in angiogenesis might be related to activation of the DCP-KDR-PLC-γ-MAPK signaling pathway. In this article, we summarized recent studies on DCP in biological roles related to cancer progression and angiogenesis in HCC.

  2. Use of Prothrombin Complex Concentrate in Patients during Heart Transplantation after Implantation of a Left Ventricular Mechanical Support System

    Directory of Open Access Journals (Sweden)

    V. V. Lomivorotov

    2012-01-01

    Full Text Available Heart transplantation in patients after implantation of mechanical cardiac support devices entails an extremely high risk for perioperative bleeding. Recombinant activated coagulation factor VII is presently used to reduce the volume of bleeding in this patient group. There are parallel data on its administration-induced thromboembolic events in the literature. This paper describes a case of using a prothrombin complex concentrate in a patient during explantation of a left ventricular bypass system and subsequent orthotopic heart transplantation in the presence of significant hypocoagulation. At the end of a surgery, 1200 IU of the agent was used at a remaining bleeding rate of more than 1000 ml/hour. Within the first 24 hours after surgery, the rate of discharge drainage was less than 100 ml/hour. A control plain chest X-ray study revealed massive left-sided hydrothorax on day 2 postsurgery. The left pleural cavity was revised under thoracoscopic guidance and 1000 ml of blood clots were evacuated. Although the administration of prothrombin complex concentrate did not guard against re-intervention, its use seems a promising strategy in life-threatening bleedings in patients after explantation of mechanical cardiac support devices. Further multicenter investigations are required to determine the efficacy and safety of prothrom-bin complex concentration in cardiac surgery. Key words: Recombinant activated coagulation factor VII, prothrombin complex concentration, mechanical cardiac support device, orthotopic heart transplantation.

    Cerebral infarction is a rare neurological situation in young adults, usually caused by genetic factors. We report here a case of multiple cerebral infarctions with prothrombin G20210A mutation, hypogonadotropic hypogonadism, and generalized vitiligo as a first case report. A 17-year-old female adolescent was admitted to our clinic due to a change in mental status. The patient's neurological examination revealed loss of consciousness and the presence of tetraparesia. Generalized vitiligo was also detected. Magnetic resonance imaging (MRI) and diffusion-weighted investigations (DWIs) showed acute ischemic stroke in the bilateral cerebellum, pons and left occipital regions. Heterozygote prothrombin G20210A mutation was found upon genetic examination. She had never had a menstrual cycle. Laboratory data revealed that the level of luteinizing hormone (LH) was 0.5 mIU/mL (1.1-11.6) and follicle-stimulating hormone (FSH) was 1.7 mIU/mL (2.8-11.3). Therefore, she was diagnosed with hypogonadotropic hypogonadism. The causes of ischemic stroke are heterozygote prothrombin G20210A mutation, generalized vitiligo, and hypogonadotropic hypogonadism. After treatment, the patient's neurological deficit partially improved and she was discharged. In order to identify the etiology of ischemic stroke, we suggest physicians take into account heterozygote prothrombin G20210A mutation and endocrine abnormalities, especially hypogonadotropic hypogonadism and generalized vitiligo.

  7. More efficient reversal of dabigatran inhibition of coagulation by activated prothrombin complex concentrate or recombinant factor VIIa than by four-factor prothrombin complex concentrate.

    2015-03-01

    The number of patients on antithrombotic treatment due to atrial fibrillation and venous thromboembolism is increasing fast due to an aging population. A growing proportion will be treated with novel oral anticoagulants, the first in clinical use was the direct oral thrombin inhibitor dabigatran (Pradaxa®). A small percentage of the patients on dabigatran will experience serious bleeding or be in need of urgent surgery. The aim of this study was to test the effects of different hemostatic agents in potentially reversing the anticoagulant effects in vitro in blood or platelet-rich plasma (PRP) spiked with dabigatran. Whole blood or PRP was spiked with the active substance dabigatran, 200 μg/L. We measured clotting time being induced by 1.4 pmol/L tissue factor using the instrument ReoRox2™ and initial clot growth velocity from a tissue factor covered surface using the instrument Thrombodynamics Analyzer T-2™. Dabigatran prolonged clotting time 5-fold but reduced clot growth velocity only slightly. The reversing effects of prothrombin complex concentrates (PCC), activated PCC (APCC) and recombinant activated factor VII (rFVIIa) were then tested. APCC (1.8 U/mL) reduced the prolonged clotting time by 1/3, rFVIIa (2 μg/L) only slightly (n = 10-20). The reduction was not significant using Mann-Whitney test but significant using t-test with Bonferronis' correction for multiple comparisons, whereas PCC (0.56 U/mL) had no effect on clotting time. APCC doubled initial clot growth velocity, although even more in the absence of dabigatran. In conclusion, APCC and rFVIIa, but not PCC, seem to reverse, at least partially, some effects of dabigatran on coagulation parameters. Systematic evaluation of case reports, registries and, ultimately, randomized clinical trials are needed to elucidate potential benefit for patients. Copyright © 2014 Elsevier Ltd.

  8. Clinical factors influencing normalization of prothrombin time after stopping warfarin: a retrospective cohort study

    Directory of Open Access Journals (Sweden)

    2008-10-01

    Full Text Available Abstract Background Anticoagulation with warfarin should be stopped 4–6 days before invasive procedures to avoid bleeding complications. Despite this routine, some patients still have high International Normalized Ratio (INR values on the day of surgery and the procedure may be cancelled. We sought to identify easily available clinical characteristics that may influence the rate of normalization of prothrombin time when warfarin is stopped before surgery or invasive procedures. Methods Clinical data were collected retrospectively from consecutive cases from two cohorts, who stopped warfarin 6 days before surgery. An INR value of 1.6 or higher on the day of surgery or requirement for reversal with vitamin K the day before surgery were criteria for slow return (S to normal INR. Results Of 202 patients, 14 (7% were classified as S. Eight of the S-patients required reversal with vitamin K one day before surgery and in another case surgery was cancelled due to high INR. Baseline INR was the only variable significantly associated with classification as S in stepwise logistic regression analysis (p = 0.003. The odds ratio for being in the normal group was 0.27 (95% confidence interval 0.12–0.62 for each unit baseline INR increased. The positive predictive value of baseline INR with a cut off at > 3.0 was only 15% and for INR > 3.5 it was 33%. Conclusion Baseline INR, but not the size of the maintenance dose, is associated with the rate of normalization of prothrombin time after stopping warfarin, but it has limited utility as predictor in clinical practice. Whenever normal hemostasis is considered crucial for the safety, the INR should be checked again before the invasive procedure.

    We have compiled MultitaskProtDB, available online at http://wallace.uab.es/multitask, to provide a repository where the many multitasking proteins found in the literature can be stored. Multitasking or moonlighting is the capability of some proteins to execute two or more biological functions. Usually, multitasking proteins are experimentally revealed by serendipity. This ability of proteins to perform multitasking functions helps us to understand one of the ways used by cells to perform many complex functions with a limited number of genes. Even so, the study of this phenomenon is complex because, among other things, there is no database of moonlighting proteins. The existence of such a tool facilitates the collection and dissemination of these important data. This work reports the database, MultitaskProtDB, which is designed as a friendly user web page containing >288 multitasking proteins with their NCBI and UniProt accession numbers, canonical and additional biological functions, monomeric/oligomeric states, PDB codes when available and bibliographic references. This database also serves to gain insight into some characteristics of multitasking proteins such as frequencies of the different pairs of functions, phylogenetic conservation and so forth.

  16. Ontogenetic view on PIVKA-II in the development of prothrombin synthesis in infants

    Directory of Open Access Journals (Sweden)

    O. G. Ivanko

    2017-12-01

    Full Text Available The aim of the research was to study the content of PIVKA-II in the blood serum as an integrative measure of latent vitamin K deficiency in breastfed infants aged from the birth to 6 months of life. Materials and methods. 178 children aged from the birth to 6 months of life who were born without birth injuries in the term of 38–41 of weeks gestation with a weight 2800–4200 g were examined. The immunoenzyme assay for PIVKA-II study was performed with ANTIBODY RESEARCH kit PIVKA-II ELISA Kit (USA Results. Children who had not received postnatal prophylactic injection of vitamin K1 in dose of 1 mg intramuscularly in their majority (62 % had abnormally elevated serum PIVKA-II (>40 Au/ml at the first week of life. In 92 % of children who had received a prophylactic dose of vitamin K1 immediately after birth, PIVKA-II was in a normal limit. The normal concentrations of PIVKA-II were observed in children aged 2–6 months regardless of vitamin K prophylactics. The situation worsened dramatically in children who were treated with antibiotics because more than 50 % of these children have experienced high PIVKA-II values. Conclusions. Almost all the children in their first week of life whom for any reasons vitamin K1 was not prescribed have exhibited an elevation of PIVKA-II in blood serum. This indicates an inborn deficiency of vitamin K experienced by fetuses and newborns. Prophylactic injection of vitamin K1 to newborns normalizes the processes of prothrombin carboxylation and PIVKA-II concentrations are getting normal. Children, who did not receive vitamin K1 after the birth, during the first month of life spontaneously normalize the PIVKA-II concentrations. The improvement of prothrombin carboxylation is obviously connected with the colon microbiota development which can provide children with well absorbed vitamin K2 (menaquinone. In 55.5 % of breastfed children aged up to 6 months who had received antibiotics the PIVKA-II appeared elevated again

    2010-11-01

    Full Text Available Abstract Background Statistical bioinformatics is the study of biological data sets obtained by new micro-technologies by means of proper statistical methods. For a better understanding of environmental adaptations of proteins, orthologous sequences from different habitats may be explored and compared. The main goal of the DeltaProt Toolbox is to provide users with important functionality that is needed for comparative screening and studies of extremophile proteins and protein classes. Visualization of the data sets is also the focus of this article, since visualizations can play a key role in making the various relationships transparent. This application paper is intended to inform the reader of the existence, functionality, and applicability of the toolbox. Results We present the DeltaProt Toolbox, a software toolbox that may be useful in importing, analyzing and visualizing data from multiple alignments of proteins. The toolbox has been written in MATLAB™ to provide an easy and user-friendly platform, including a graphical user interface, while ensuring good numerical performance. Problems in genome biology may be easily stated thanks to a compact input format. The toolbox also offers the possibility of utilizing structural information from the SABLE or other structure predictors. Different sequence plots can then be viewed and compared in order to find their similarities and differences. Detailed statistics are also calculated during the procedure. Conclusions The DeltaProt package is open source and freely available for academic, non-commercial use. The latest version of DeltaProt can be obtained from http://services.cbu.uib.no/software/deltaprot/. The website also contains documentation, and the toolbox comes with real data sets that are intended for training in applying the models to carry out bioinformatical and statistical analyses of protein sequences. Equipped with the new algorithms proposed here, DeltaProt serves as an auxiliary

    Vascular access-related complications are a frequent cause of morbidity in haemodialysis patients and generate high costs. We present the case of an adult patient with end-stage renal disease and recurrent vascular access thrombosis associated with the prothrombin mutation G20210A and renal graft intolerance. The clinical expression of this heterozygous gene mutation may have been favoured by inflammatory state, frequent in dialysis patients. In this patient, the inflammatory response associated with the renal graft intolerance would have favored the development of recurrent vascular access thrombosis in a adult heterozygous for prothrombin mutation G20210A. In the case of early dysfunction of haemodialysis vascular access and after ruling out technical problems, it is convenient to carry out a screening for thrombophilia.

    2007-04-01

    Measurements of serum concentrations of des-gamma-carboxy-prothrombin (PIVKA-II) are widely used for diagnosing hepatocellular carcinoma (HCC). Recently, when we evaluated the correlation of PIVKA-II between two commercially available PIVKA-II immunoassay kits (Lumipulse f vs. Picolumi) to introduce it in our hospital, false high values of PIVKA-II were observed in Lumipulse assay. Four(4%) of 100 serum samples showed false high values, and all of them were obtained from patients less than 2 month after curative resection of HCC. Examining additional 7 patients with HCC resection, serum samples from the 5 patients had the same trend. To elucidate the non-specific reaction by Lumipulse assay which utilized alkaline phosphatase (ALP) enzymatic reaction, inhibition assays by various absorbents such as inactive ALP and IgM antibodies were performed. Excess of inactive ALP reduced the high values of PIVKA-II. Note that anti-bleeding sheets (fibrinogen combined drug), which included bovine thrombin, were directly attached on liver of all patients with HCC resection in this study. As the sheets also contaminate ALP and probably produce IgM antibodies to ALP, the IgM may cross-react with anti-PIVKA-II antibodies directly. Taken together, it was suggested that produced antibodies against ALP derived from anti-bleeding sheets led false high values of PIVKA-II in the patients with HCC resection.

    Antiphospholipid syndrome (APS) is an autoimmune disorder characterized by thrombosis and/or pregnancy-related morbidity accompanied by persistently positive antiphospholipid antibodies (aPL). Current laboratory criteria for APS classification recommend testing for lupus anticoagulant as well as IgG and IgM anticardiolipin, and beta-2 glycoprotein I (anti-β2GPI) antibodies. However, there appears to be a subset of patients with classical APS manifestations who test negative for the recommended criteria aPL tests. While acknowledging that such patients may have clinical features that are not of an autoimmune etiology, experts also speculate that these "seronegative" patients may test negative for relevant autoantibodies as a result of a lack of harmonization and/or standardization. Alternatively, they may have aPL that target other antigens involved in the pathogenesis of APS. In the latter, autoantibodies that recognize a phosphatidylserine/prothrombin (PS/PT) complex have been reported to be associated with APS and may have diagnostic relevance. This review highlights analytical and clinical attributes associated with PS/PT antibodies, taking into consideration the performance characteristics of criteria aPL tests in APS with specific recommendations for harmonization and standardization efforts. © 2016 Elsevier Inc.

    Mentorship has been identified as an influential factor in retaining new nursing faculty. A mentor-protégé program for novice faculty was implemented to promote development of the protégés in their role as nurse educators. A qualitative research study conducted to illuminate the meaning of experiences of mentors led to the emergence of four patterns: The Significance of the Mentor-Protégé Relationship, Communication as Important Between Mentor and Protégé, The Mentor-Protégé Program-Protégé's Perspectives, and The Mentoring Role as Expert Educator. The data from the study support the significance of providing mentorship to novice or new nurse educators. The data suggest that mentors benefit from participation in a mentor-protégé program as much as the protégés. Similar programs are needed in nursing if we are to mentor and encourage faculty to begin and remain in the role of educators to combat the future nurse educator shortage.

    Epithelial ovarian cancer (EOC) frequently metastasises to the omentum, a process that requires pro-angiogenic activation of human omental microvascular endothelial cells (HOMECs) by tumour-secreted factors. We have previously shown that ovarian cancer cells secrete a range of factors that induce pro-angiogenic responses e.g. migration, in HOMECs including the lysosomal protease cathepsin D (CathD). However, the cellular mechanism by which CathD induces these cellular responses is not understood. The aim of this study was to further examine the pro-angiogenic effects of CathD in HOMECs i.e. proliferation and migration, to investigate whether these effects are dependent on CathD catalytic activity and to delineate the intracellular signalling kinases activated by CathD. We report, for the first time, that CathD significantly increases HOMEC proliferation and migration via a non-proteolytic mechanism resulting in activation of ERK1/2 and AKT. These data suggest that EOC cancer secreted CathD acts as an extracellular ligand and may play an important pro-angiogenic, and thus pro-metastatic, role by activating the omental microvasculature during EOC metastasis to the omentum.

    Objective: The objective of this study was to evaluate the effectiveness of 3-factor prothrombin complex concentrate (3F-PCC) compared to 4-factor PCC (4F-PCC) in warfarin-associated bleeding. Methods: This multicenter, retrospective, cohort study analyzed data from patients admitted between May 2011 and October 2014 who received PCC for warfarin-associated bleeding. The primary outcome was the rate of international normalized ratio (INR) normalization, defined as an INR ≤1.3, after administration of 3F-PCC compared to 4F-PCC. Other variables of interest included the incidence of additional reversal agents, new thromboembolic events, and mortality. Results: A total of 134 patients were included in the analysis. The average dose of PCC administered was 24.6 ± 9.3 units/kg versus 36.3 ± 12.8 units/kg in the 3F-PCC and 4F-PCC groups, respectively, P < 0.001. Baseline INR in the 3F-PCC and 4F-PCC groups was 3.61 ± 2.3 and 6.87 ± 2.3, respectively P < 0.001. 4F-PCC had a higher rate of INR normalization at first INR check post-PCC administration compared to 3F-PCC (84.2% vs. 51.9%, P = 0.0001). Thromboembolic events, intensive care unit and hospital length of stay, and mortality were similar among both groups. Conclusion: The use of 4F-PCC leads to a more significant reduction in INR compared to 3F-PCC though no difference in mortality or length of stay was observed. Thromboembolism rates were similar among both groups. PMID:29619338

    Among the diagnostic assays for anti-phospholipid syndrome (APS), lupus anticoagulant (LA) is the strongest predictor of thrombosis; however, it presents several limitations as interference with anticoagulant therapy and poor inter-laboratory agreement. Two-thirds of LA activity is apparently due to antibodies against prothrombin (PT), usually detectable by ELISA. Binding of PT to phosphatidylserine (PS) has been shown to enhance solid-phase anti-PT assay sensitivity. To determine the prevalence of antibodies against PS/PT (aPS/PT) in APS, we tested the semiquantitative QUANTA Lite(®) aPS/PT ELISA in a cohort of 80 APS patients. The prevalence of aPS/PT was 81.3%, rising to 87.6% when considering LA-positive subjects only. We observed a strong correlation between aPS/PT and LA (p = 0.006). To note, APS patients with thrombotic manifestations displayed significantly higher IgG aPS/PT titers compared to 20 aPL asymptomatic carriers (p = 0.012). To rule out a possible cross-reactivity of anti-β2 glycoprotein I antibodies (aβ2GPI) with PS/PT complex, we tested two monoclonal aβ2GPI antibodies and an affinity-purified (AP) polyclonal aβ2GPI IgG obtained from the serum of a patient reacting against both β2GPI and PS/PT. The two monoclonal antibodies did not show any reactivity against PS/PT complex, similarly the AP IgGs did not react toward PS/PT antigen while preserved their aβ2GPI activity. Our findings suggest that aPS/PT are a definite antibody population in APS. Moreover, the good correlation between aPS/PT ELISA and LA may support its use as a surrogate test for LA, particularly useful to overcome the technical limitations of the functional assay.

    RaftProt (http://lipid-raft-database.di.uq.edu.au/) is a database of mammalian lipid raft-associated proteins as reported in high-throughput mass spectrometry studies. Lipid rafts are specialized membrane microdomains enriched in cholesterol and sphingolipids thought to act as dynamic signalling and sorting platforms. Given their fundamental roles in cellular regulation, there is a plethora of information on the size, composition and regulation of these membrane microdomains, including a large number of proteomics studies. To facilitate the mining and analysis of published lipid raft proteomics studies, we have developed a searchable database RaftProt. In addition to browsing the studies, performing basic queries by protein and gene names, searching experiments by cell, tissue and organisms; we have implemented several advanced features to facilitate data mining. To address the issue of potential bias due to biochemical preparation procedures used, we have captured the lipid raft preparation methods and implemented advanced search option for methodology and sample treatment conditions, such as cholesterol depletion. Furthermore, we have identified a list of high confidence proteins, and enabled searching only from this list of likely bona fide lipid raft proteins. Given the apparent biological importance of lipid raft and their associated proteins, this database would constitute a key resource for the scientific community. © The Author(s) 2014.

    Full Text Available DNA-binding proteins are crucial for various cellular processes, such as recognition of specific nucleotide, regulation of transcription, and regulation of gene expression. Developing an effective model for identifying DNA-binding proteins is an urgent research problem. Up to now, many methods have been proposed, but most of them focus on only one classifier and cannot make full use of the large number of negative samples to improve predicting performance. This study proposed a predictor called enDNA-Prot for DNA-binding protein identification by employing the ensemble learning technique. Experiential results showed that enDNA-Prot was comparable with DNA-Prot and outperformed DNAbinder and iDNA-Prot with performance improvement in the range of 3.97–9.52% in ACC and 0.08–0.19 in MCC. Furthermore, when the benchmark dataset was expanded with negative samples, the performance of enDNA-Prot outperformed the three existing methods by 2.83–16.63% in terms of ACC and 0.02–0.16 in terms of MCC. It indicated that enDNA-Prot is an effective method for DNA-binding protein identification and expanding training dataset with negative samples can improve its performance. For the convenience of the vast majority of experimental scientists, we developed a user-friendly web-server for enDNA-Prot which is freely accessible to the public.

    SWISS-PROT is a curated protein sequence database which strives to provide a high level of annotation, a minimal level of redundancy and high level of integration with other databases. Ongoing genome sequencing projects have dramatically increased the number of protein sequences to be incorporated into SWISS-PROT. Since we do not want to dilute the quality standards of SWISS-PROT by incorporating sequences without proper sequence analysis and annotation, we cannot speed up the incorporation of new incoming data indefinitely. However, as we also want to make the sequences available as fast as possible, we introduced TREMBL (TRanslation of EMBL nucleotide sequence database), a supplement to SWISS-PROT. TREMBL consists of computer-annotated entries in SWISS-PROT format derived from the translation of all coding sequences (CDS) in the EMBL nucleotide sequence database, except for CDS already included in SWISS-PROT. While TREMBL is already of immense value, its computer-generated annotation does not match the quality of SWISS-PROTs. The main difference is in the protein functional information attached to sequences. With this in mind, we are dedicating substantial effort to develop and apply computer methods to enhance the functional information attached to TREMBL entries.

    The clinical manifestations of scrub typhus, murine typhus and acute Q fever in the elderly are not clear. We conducted a retrospective study to identify the characteristics of the elderly aged ≥65 years with a comparison group aged 18-64 years among patients with scrub typhus, murine typhus, or acute Q fever who were serologically confirmed at three hospitals in Taiwan during 2002-2011. Among 441 cases, including 187 cases of scrub typhus, 166 acute Q fever, and 88 murine typhus, 68 (15.4%) cases were elderly patients. The elderly had a higher severe complication rate (10.3% vs. 3.5%, p = 0.022), but did not have a significantly higher mortality rate (1.47% vs. 0.54%, p = 0.396). Compared with those without severe complications, we found the elderly (p = 0.022), dyspnea (p = 0.006), less relative bradycardia (p = 0.004), less febrile illness (p = 0.004), prolonged prothrombin time (PT) (p = 0.002), higher levels of initial C-reactive protein (p = 0.039), blood leukocyte counts (p = 0.01), and lower platelet counts (p = 0.012) are significantly associated with severe complications. Only prolonged prothrombin time was associated with severe complications in multivariate analysis (p = 0.018, CI 95% 0.01-0.66). Among clinical symptoms and laboratory data, multivariate analysis revealed chills was less frequently occurred in the elderly (p = 0.012, 95% confidence interval [CI]: 1.33-9.99). The elderly cases with scrub typhus, murine typhus, or acute Q fever would be more likely to have severe complications, for which prothrombin time prolongation is an important predictor for severe complications.

  3. UniProtKB amid the turmoil of plant proteomics research

    Directory of Open Access Journals (Sweden)

    Michel eSchneider

    2012-12-01

    Full Text Available The UniProt knowledgebase (UniProtKB provides a single, centralized, authoritative resource for protein sequences and functional information. The majority of its records is based on automatic translation of coding sequences (CDS provided by submitters at the time of initial deposition to the nucleotide sequence databases (INSDC. More and more frequently, only the raw sequence of a complete genome is deposited to the nucleotide sequence databases and the gene model predictions and annotations are kept in separate, specialized model organism databases (MODs. In order to be able to provide the complete proteome of model organisms, UniProtKB had to implement pipelines for import of protein sequences from Ensembl and EnsemblGenomes.A single genome can be the target of several unrelated sequencing projects and the final assembly and gene model predictions may diverge quite significantly. In addition, several cultivars of the same species are often sequenced -1001 Arabidopsis cultivars are currently under way- and the resulting proteomes are far from being identical. Therefore, one challenge for UniProtKB is to store and organize these data in a convenient way and to clearly defined reference proteomes that should be made available to users. Manual annotation is one of the landmarks of the Swiss-Prot section of UniProtKB. Besides adding functional annotation, curators are checking, and often correcting, gene model predictions. For plants, this task is limited to Arabidopsis thaliana and Oryza sativa subsp japonica. Proteomics data providing experimental evidences confirming the existence of proteins or identifying sequence features such as post translational modifications are also imported into UniProtKB records and the knowledgebase is cross-referenced to numerous proteomics resources.

    2010-06-03

    The role of mentorship in protégé performance is a matter of importance to academic, business and governmental organizations. Although the benefits of mentorship for protégés, mentors and their organizations are apparent, the extent to which protégés mimic their mentors' career choices and acquire their mentorship skills is unclear. The importance of a science, technology, engineering and mathematics workforce to economic growth and the role of effective mentorship in maintaining a 'healthy' such workforce demand the study of the role of mentorship in academia. Here we investigate one aspect of mentor emulation by studying mentorship fecundity-the number of protégés a mentor trains-using data from the Mathematics Genealogy Project, which tracks the mentorship record of thousands of mathematicians over several centuries. We demonstrate that fecundity among academic mathematicians is correlated with other measures of academic success. We also find that the average fecundity of mentors remains stable over 60 years of recorded mentorship. We further discover three significant correlations in mentorship fecundity. First, mentors with low mentorship fecundities train protégés that go on to have mentorship fecundities 37% higher than expected. Second, in the first third of their careers, mentors with high fecundities train protégés that go on to have fecundities 29% higher than expected. Finally, in the last third of their careers, mentors with high fecundities train protégés that go on to have fecundities 31% lower than expected.

    Increased levels of urine prothrombin fragment 1 + 2 was recently reported to be associated with imaging-verified venous thromboembolism. In this study we evaluated the relationship between plasma D-dimer and plasma and urine prothrombin fragment 1 + 2 in patients with suspected venous thromboembolism. Urine and blood samples were collected from patients with suspected pulmonary embolism or deep vein thrombosis. The samples were analysed with commercially available ELISA kits. The diagnosis of venous thromboembolism was verified with contrast-enhanced computer tomography of the pulmonary arteries or lower extremity deep vein compression ultrasound and venography as appropriate. Venous thromboembolism was diagnosed in 150 of 720 patients. Significantly higher levels of plasma D-dimer and prothrombin fragment 1 + 2 in plasma and urine were found in those with imaging-confirmed venous thromboembolism versus those without (P fragment 1 + 2 in plasma. Further development of ELISA analyses for urine testing of prothrombin fragment 1 + 2 may improve its diagnostic accuracy.

The purpose of this study was to assess whether the value of prothrombin time (PT, activated partial thromboplastin time (aPTT, fibrinogen, and D-dimer levels can be used as predictors of decompensated DIC in sepsis patients. This study was conducted at the Laboratory of Clinical Pathology Rumah Sakit Hasan Sadikin Bandung since September 2008 to June 2010. Subjects were patients with sepsis caused by pneumonia. PT and aPTT values, fibrinogen, and D-dimer levels was recorded from all sepsis patients then patients were observed until diagnosed decompensated or non-decompensated DIC, then the value of PT, aPTT, fibrinogen and D-dimer levels in the group of decompensated DIC and non-decompensated DIC were analysed. This study used cohort design. Subjects were 39 sepsis patients (58% with outcome decompensated DIC and 28 sepsis patients (42% with outcome non-decompensated DIC. From the hemostasis parameter test out, it was found that PT, aPTT, and fibrinogen were the predictor of decompensated DIC in patients with sepsis with relative risk 240.500, 7.157, and 6.421; respectively. Conclusions, prothrombin time, aPTT, fibrinogen are the test to know coagulation activation. Hemostasis parameter to predict decompensated DIC in sepsis patients are the shorten PT, aPTT, and the increased fibrinogen

    Full Text Available Physicians usually do not suspect pulmonary thromboembolism in younger patients except in those who have thrombophilia. In those latter patients some special conditions such as trauma or surgery may provoke the disease. In some adult persons, thrombophilia may still remain unrecognized, until appearance of additional conditions influence development of thrombosis. A 55-year-old Caucasian female, non-smoker, experienced sudden chest pain and hemoptysis without chest trauma. History taking revealed type 2 diabetes mellitus and hypothyroidism. She was overweight with body mass index 29.0. The review of the family history revealed that her father and mother died of brain infarction, while her 22-year-old son and 24-year-old daughter were healthy. Due to suspicion for thrombosis, multi-slice computerized tomography thorax scan was done and pulmonary embolism was diagnosed. Although without clear risk factor for thrombosis in our patient, we performed laboratory investigation for congenital thrombophilia. Genetic analysis showed double heterozygous for factor V Leiden and prothrombin 20210 G>A mutations. Congenital thrombophilia was risk factor for thrombosis in our patient but haemostatic imbalance was not previously clinically recognized. She had two pregnancies without complications. Appearance of other associative factors such as endocrine disorders - hypothyroidism and metabolic syndrome with diabetes type 2, and overweigh were additional potential triggers for clinical manifestation of pulmonary thromboembolism in her adult age. Her children underwent genetic analysis, too. The son was also double heterozygous for factor V Leiden and prothrombin 20210 G>A mutations, while daughter was heterozygous for factor V Leiden, and none had clinical signs of thrombosis.

    Full Text Available SWISS-PROT is a curated, non-redundant protein sequence database which provides a high level of annotation and is integrated with a large number of other biological databases. It is supplemented by TrEMBL, a computer-annotated database which contains translations of all coding sequences in the EMBL Nucleotide Sequence Database which are not yet in SWISS-PROT. Each fully curated SWISS-PROT entry contains as much up-to-date information as possible from a variety of sources and the high quality of the annotation in SWISS-PROT provides the basis for the procedure which is used to automatically annotate the TrEMBL database. The large amounts of different data types found in both databases are stored in a highly structured and uniform manner and this structured organisation means that SWISS-PROT and TrEMBL together provide a comprehensive resource with data that are readily accessible for users and easily retrievable by computer programs.

    Abstract There is a continuous interest in increasing proteins stability to enhance their usability in numerous biomedical and biotechnological applications. A number of in silico tools for the prediction of the effect of mutations on protein stability have been developed recently. However, only single-point mutations with a small effect on protein stability are typically predicted with the existing tools and have to be followed by laborious protein expression, purification, and characterization. Here, we present FireProt, a web server for the automated design of multiple-point thermostable mutant proteins that combines structural and evolutionary information in its calculation core. FireProt utilizes sixteen tools and three protein engineering strategies for making reliable protein designs. The server is complemented with interactive, easy-to-use interface that allows users to directly analyze and optionally modify designed thermostable mutants. FireProt is freely available at http://loschmidt.chemi.muni.cz/fireprot. PMID:28449074

    Idiopathic cerebral-vein thrombosis can cause serious neurologic disability. We evaluated risk factors for this disorder, including genetic risk factors (mutations in the genes encoding factor V and prothrombin) and nongenetic risk factors (such as the use of oral contraceptive agents). We compared the prevalence of these risk factors in 40 patients with cerebral-vein thrombosis, 80 patients with deep-vein thrombosis of the lower extremities, and 120 healthy controls. The G1691A mutation in the factor V gene and the G20210A prothrombin-gene mutation, which are established genetic risk factors for venous thrombosis, were studied. We also assessed the use of oral contraceptives and other risk factors for thrombosis. The prevalence of the prothrombin-gene mutation was higher in patients with cerebral-vein thrombosis (20 percent) than in healthy controls (3 percent; odds ratio, 10.2; 95 percent confidence interval, 2.3 to 31.0) and was similar to that in patients with deep-vein thrombosis (18 percent). Similar results were obtained for the mutation in the factor V gene. The use of oral contraceptives was more frequent among women with cerebral-vein thrombosis (96 percent) than among controls (32 percent; odds ratio, 22.1; 95 percent confidence interval, 5.9 to 84.2) and among those with deep-vein thrombosis (61 percent; odds ratio, 4.4; 95 percent confidence interval, 1.1 to 17.8). For women who were taking oral contraceptives and who also had the prothrombin-gene mutation (seven patients with cerebral-vein thrombosis but only one control), the odds ratio for cerebral-vein thrombosis rose to 149.3 (95 percent confidence interval, 31.0 to 711.0). Mutations in the prothrombin gene and the factor V gene are associated with cerebral-vein thrombosis. The use of oral contraceptives is also strongly and independently associated with the disorder. The presence of both the prothrombin-gene mutation and oral-contraceptive use raises the risk of cerebral-vein thrombosis further.

  1. A novel prothrombin time method to measure all non-vitamin K-dependent oral anticoagulants (NOACs)

    Lindahl, Tomas L.; Arbring, Kerstin; Wallstedt, Maria; Rånby, Mats

    2017-01-01

    Background There is a clinical need for point-of-care (POC) methods for non-vitamin K-dependent oral anticoagulants (NOACs). We modified a routine POC procedure: Zafena’s Simple Simon™ PT-INR, a room-temperature, wet-chemistry prothrombin time method of the Owren-type. Methods To either increase or decrease NOAC interference, two assay variants were devised by replacing the standard 10 µL end-to-end capillary used to add the citrated plasma sample to 200 µL of prothrombin time (PT) reagent by either a 20 µL or a 5 µL capillary. All assay variants were calibrated to show correct PT results in plasma samples from healthy and warfarin-treated persons. Results For plasmas spiked with dabigatran, apixaban, or rivaroxaban, the 20 µL variant showed markedly higher PT results than the 5 µL. The effects were even more pronounced at room temperature than at +37 °C. In plasmas from patients treated with NOACs (n = 30 for each) there was a strong correlation between the PT results and the concentration of NOACs as determined by the central hospital laboratory. For the 20 µL variant the PT response of linear correlation coefficient averaged 0.90. The PT range was INR 1.1–2.1 for dabigatran and apixaban, and INR 1.1–5.0 for rivaroxaban. Using an INR ratio between the 20 µL and 5 µL variants (PTr20/5) made the NOAC assay more robust and independent of the patient sample INR value in the absence of NOAC. Detection limits were 80 µg/L for apixaban, 60 µg/L for dabigatran, and 20 µg/L for rivaroxaban. Conclusions A wet-chemistry POC PT procedure was modified to measure the concentrations of three NOACs using a single reagent. PMID:28891412

    The coagulopathy of trauma is generally confirmed by prothrombin time (PT) > or =16 seconds or an international normalized ratio > or =1.5. However, the utility of these values as a screening test is unknown. We examined different coagulation tests to determine the best predictor of coagulopathic bleeding and mortality in a small animal hemorrhage model. Coagulopathy was induced in male New Zealand White rabbits by warfarin (W; 2 mg/kg for 2 days; n = 7), or hemodilution and hypothermia (HH; 50% blood exchange with Hextend, 34.5 +/- 0.3 degrees C; n = 7). Normal (N) rabbits without pretreatment served as the control (n = 7). Blood samples collected after coagulopathy induction and analyzed by prothrombin time (PT), activated partial thromboplastin time (aPTT), and thromboelastography (TEG) tests. Liver bleeding time (BT) was also measured before injury. An uncontrolled hemorrhage was created by a longitudinal splenic incision and the abdomen was closed. Rabbits were resuscitated with Hextend solution (25 mL/kg) to return blood pressure to baseline and monitored for 2 hours or until death at which time blood loss was measured. Warfarin-induced coagulopathy increased BT, PT, and aPTT. TEG showed increased reaction (R) and clot formation (K) times and marked decrease in clotting rate (alpha angle and Vmax). Hemodilution hypothermia coagulopathy increased only BT and aPTT, and decreased the clotting rate (alpha angle and Vmax) and strength of the clot. After injury, blood losses were higher in coagulopathic rabbits (W = 54.6 +/- 4.2 and HH = 51.1 +/- 8.9 mL/kg) than in normal rabbits (30.6 +/- 12.4 mL/kg) and resulted in 86%, 100%, and 0% death, respectively. BT and Vmax consistently predicted coagulopathic bleeding and death in all animals. Although satisfactory in warfarin-induced coagulopathy, PT was not a valid screening test for dilutional and hypothermic coagulopathy. BT and TEG measurements of blood clotting rate are better indicators of coagulopathic bleeding

    To compare outcomes following inactive prothrombin complex concentrate (PCC) or recombinant activated factor VII (rFVIIa) administration during cardiac surgery. Retrospective propensity-matched analysis. Academic tertiary-care center. Patients undergoing cardiac surgery requiring cardiopulmonary bypass who received either rFVIIa or the inactive 3-factor PCC. Outcomes following intraoperative administration of rFVIIa (263) or factor IX complex (72) as rescue therapy to treat bleeding. In the 24 hours after surgery, propensity-matched patients receiving PCC versus rFVIIa had significantly less chest tube outputs (median difference -464 mL, 95% confidence interval [CI] -819 mL to -110 mL), fresh frozen plasma transfusion rates (17% v 38%, p = 0.028), and platelet transfusion rates (26% v 49%, p = 0.027). There were no significant differences between propensity-matched groups in postoperative stroke, deep venous thrombosis, pulmonary embolism, myocardial infarction, or intracardiac thrombus. Postoperative dialysis was significantly less likely in patients administered PCC versus rFVIIa following propensity matching (odds ratio = 0.3, 95% CI 0.1-0.7). No significant difference in 30-day mortality in patients receiving PCC versus rFVIIa was present following propensity matching. Use of rFVIIa versus inactive PCCs was significantly associated with renal failure requiring dialysis and increased postoperative bleeding and transfusions. Copyright © 2018 Elsevier Inc.

    Antiphospholipid syndrome is an autoimmune disorder characterized by the occurrence of venous and arterial thrombosis, as well as morbidity in pregnancy, in the presence of anti-phospholipid antibodies. The diagnosis of antiphospholipid syndrome is usually established based on clinical and laboratory findings by strictly following the 2006 Sapporo classification. However, the diagnosis remains challenging owing to the ongoing debates on the serological criteria. We report a case we describe as forme fruste antiphospholipid syndrome in which these criteria were not fulfilled. Purpura appeared repeatedly in a female infant starting from the age of 6 months and following episodes of upper respiratory infections and vaccinations. The levels of anti-cardiolipin IgG antibodies and anti-phosphatidylserine/prothrombin complex antibodies were elevated in accordance with these events. Histopathological evaluation revealed multiple small vessel thrombi in the dermis and adipose tissue. After 2 weeks of treatment with aspirin and heparin, the cutaneous symptoms subsided. Infection has long been associated with antiphospholipid syndrome, and anti-phosphatidylserine/prothrombin antibodies are considered a new marker for the diagnosis of antiphospholipid syndrome. Forme fruste antiphospholipid syndrome should be considered even if the antiphospholipid syndrome diagnostic criteria are not completely fulfilled, especially in the presence of elevated levels of anti-phosphatidylserine/prothrombin antibodies and known preceding infections.

  5. EFFECT OF METHANOLIC SEED EXTRACT OF PERSEA AMERICANA(AVOCADO PEAR ON PROTHROMBIN TIME AND ACTIVATED PARTIAL THROMBOPLASTIN TIME IN MICE

    Directory of Open Access Journals (Sweden)

    2016-11-01

    Full Text Available Twenty (20 adult albino mice were used in the study to determine the effect of methanolic seed extract of Persea Americana on prothrombin time (PT and activated partial thromboplastin time (APTT test. The mice were obtained and kept for 2 weeks to acclimatize. They were weighed and divided into 5 groups. Group A served as control without the extract. Groups B to E were orally administered with graded doses of 200mg, 400 mg, 800 mg and 1600mg/kg body weight per mice daily for 28 days. Blood samples were collected through the median canthus into ti-sodium citrate anticoagulant containers for the analysis of PT and APTT, using standard operative procedure. The analysis was carried out at the Haematology Laboratory of University of Nigeria Teaching Hospital (UNTH Enugu. The results showed a prolonged APTT time at all the doses of the extract when compared with the control (P and lt;0.05. The prothrombin time at the dosage of 200mg/kg did not differ when compared with the control (P and gt;0.05. The increase in PT and APTT was dose dependent. This result pattern suggests that the extract causes prolonged prothrombin time and APTT at various concentrations possibly due to its high potassium content. The extract can be recommended in anticoagulant therapy since it prolongs PT and APTT.

    2010-04-01

    Full Text Available Abstract Introduction Hereditary causes of visceral thrombosis or thrombosis should be sought among young patients. We present a case of a young man presenting with multiple hepatic infarctions resulting in portal hypertension due to homozygosity of the prothrombin gene mutation not previously described in literature. Case presentation A 42-year-old Caucasian man with a previous history of idiopathic deep vein thrombosis 11 years earlier presented with vague abdominal pains and mildly abnormal liver function tests. An ultrasound and computed tomography scan showed evidence of hepatic infarction and portal hypertension (splenic varices. A thrombophilia screen confirmed a homozygous mutation for the prothrombin gene mutation, with mildly reduced levels of anti-thrombin III (AT III. Subsequent testing of his father and brother revealed heterozygosity for the same gene mutation. Conclusion Hepatic infarction is unusual due to the rich dual arterial and venous blood supply to the liver. In the absence of an arterial or haemodynamic insult causing hepatic infarction, a thrombophilia should be considered. To our knowledge, this is the first reported case of a hepatic infarction due to homozygosity of the prothrombin gene mutation. It is unclear whether homozygotes have a higher risk of thrombosis than heterozygotes. In someone presenting with a first thrombosis with this mutation, the case for life-long anticoagulation is unclear, but it may be necessary to prevent a second and more severe second thrombotic event, as occurred in this case.

    About 5000 (25%) of the ~20400 human protein-coding genes currently lack any experimental evidence at the protein level. For many others, there is only little information relative to their abundance, distribution, subcellular localization, interactions, or cellular functions. The aim of the HUPO Human Proteome Project (HPP, www.thehpp.org ) is to collect this information for every human protein. HPP is based on three major pillars: mass spectrometry (MS), antibody/affinity capture reagents (Ab), and bioinformatics-driven knowledge base (KB). To meet this objective, the Chromosome-Centric Human Proteome Project (C-HPP) proposes to build this catalog chromosome-by-chromosome ( www.c-hpp.org ) by focusing primarily on proteins that currently lack MS evidence or Ab detection. These are termed "missing proteins" by the HPP consortium. The lack of observation of a protein can be due to various factors including incorrect and incomplete gene annotation, low or restricted expression, or instability. neXtProt ( www.nextprot.org ) is a new web-based knowledge platform specific for human proteins that aims to complement UniProtKB/Swiss-Prot ( www.uniprot.org ) with detailed information obtained from carefully selected high-throughput experiments on genomic variation, post-translational modifications, as well as protein expression in tissues and cells. This article describes how neXtProt contributes to prioritize C-HPP efforts and integrates C-HPP results with other research efforts to create a complete human proteome catalog.

    The UniProt consortium was formed in 2002 by groups from the Swiss Institute of Bioinformatics (SIB), the European Bioinformatics Institute (EBI) and the Protein Information Resource (PIR) at Georgetown University, and soon afterwards the website http://www.uniprot.org was set up as a central entry point to UniProt resources. Requests to this address were redirected to one of the three organisations' websites. While these sites shared a set of static pages with general information about UniProt, their pages for searching and viewing data were different. To provide users with a consistent view and to cut the cost of maintaining three separate sites, the consortium decided to develop a common website for UniProt. Following several years of intense development and a year of public beta testing, the http://www.uniprot.org domain was switched to the newly developed site described in this paper in July 2008. The UniProt consortium is the main provider of protein sequence and annotation data for much of the life sciences community. The http://www.uniprot.org website is the primary access point to this data and to documentation and basic tools for the data. These tools include full text and field-based text search, similarity search, multiple sequence alignment, batch retrieval and database identifier mapping. This paper discusses the design and implementation of the new website, which was released in July 2008, and shows how it improves data access for users with different levels of experience, as well as to machines for programmatic access.http://www.uniprot.org/ is open for both academic and commercial use. The site was built with open source tools and libraries. Feedback is very welcome and should be sent to help@uniprot.org. The new UniProt website makes accessing and understanding UniProt easier than ever. The two main lessons learned are that getting the basics right for such a data provider website has huge benefits, but is not trivial and easy to underestimate

    The rapid reversal of the effects of vitamin K antagonists is often required in cases of emergency surgery and life-threatening bleeding, or during bleeding associated with high morbidity and mortality such as intracranial haemorrhage. Increasingly, four-factor prothrombin complex concentrates (PCCs) containing high and well-balanced concentrations of vitamin K-dependent coagulation factors are recommended for emergency oral anticoagulation reversal. Both the safety and efficacy of such products are currently in focus, and their administration is now expanding into the critical care setting for the treatment of life-threatening bleeding and coagulopathy resulting either perioperatively or in cases of acute trauma. After 15 yr of clinical use, findings of a pharmacovigilance report (February 1996-March 2012) relating to the four-factor PCC Beriplex P/N (CSL Behring, Marburg, Germany) were analysed and are presented here. Furthermore, a review of the literature with regard to the efficacy and safety of four-factor PCCs was performed. Since receiving marketing authorization (February 21, 1996), ~647 250 standard applications of Beriplex P/N have taken place. During this time, 21 thromboembolic events judged to be possibly related to Beriplex P/N administration have been reported, while no incidences of viral transmission or heparin-induced thrombocytopenia were documented. The low risk of thromboembolic events reported during the observation period (one in ~31 000) is in line with the incidence observed with other four-factor PCCs. In general, four-factor PCCs have proven to be well tolerated and highly effective in the rapid reversal of vitamin K antagonists.

    In vivo animal data have shown prothrombin complex concentrate (PCC) to be effective in preventing bleeding induced by excessive plasma levels of the direct thrombin inhibitor dabigatran. This animal model study was designed to determine the risk of thrombosis associated with administration of a PCC (Beriplex P/N) to reverse dabigatran-induced bleeding. Anesthetized rabbits were treated with initial 0, 75, 200 or 450 μg kg(-1) dabigatran boluses followed by continuous infusions to maintain elevated plasma dabigatran levels. At 15 min after the start of dabigatran administration, PCC doses of 0, 50 or 300 IU kg(-1) were administered. Thereafter, coagulation in an arteriovenous (AV) shunt was evaluated and histopathologic examination for thrombotic changes performed. Venous thrombosis was also assessed in a modified Wessler model. At the suprapharmacologic dose of 300 IU kg(-1), PCC increased thrombus weight during AV shunting, but this effect could be prevented by dabigatran at all tested doses. AV shunt occlusion after PCC administration was delayed by 75 μg kg(-1) dabigatran and abolished by progressively higher dabigatran doses. High-dose treatment with 300 IU kg(-1) PCC resulted in histologically evident low-grade pulmonary thrombi; however, that effect could be blocked by dabigatran in a dose-dependent manner (p=0.034). In rabbits treated with high-dose PCC, dabigatran inhibited thrombus formation during venous stasis. PCC effectively reversed dabigatran-induced bleeding. In this animal study, thrombosis after PCC administration could be prevented in the presence of dabigatran. PCC reversed dabigatran-induced excessive bleeding while retaining protective anticoagulatory activity of dabigatran. Copyright © 2014. Published by Elsevier Ltd.

    Plasminogen-activator inhibitor (PAI)-1 is an important inhibitor of the plasminogen/plasmin system. PAI-1 levels are influenced by the 4G/5G polymorphism in the PAI-1 promoter. We investigated the relationship between the PAI-1 polymorphism and VTE recurrence, and its possible modification by factor V Leiden (FVL) and prothrombin (PTM) mutations. Patients (n=1,069) from the Malmö Thrombophilia Study were followed from discontinuation of anticoagulant treatment until diagnosis of VTE recurrence or the end of the study (maximum follow-up 9.8 years). One hundred twenty-seven patients (11.9 %) had VTE recurrence. PAI-1 was genotyped by TaqMan PCR. Cox regression analysis adjusted for age, sex and acquired risk factors of VTE showed no evidence of an association between PAI-1 genotype and risk of VTE recurrence in the study population as a whole. However, by including an interaction term in the analysis we showed that FVL but not PTM modified the effect of PAI-1 genotype: patients with the 4G allele plus FVL had a higher risk of VTE recurrence [hazard ratio (HR) =2.3, 95 % confidence interval (CI) =1.5-3.3] compared to patients with the 4G allele but no FVL (reference group) or FVL irrespective of PAI-1 genotype (HR=1.8, 95 % CI=1.3-2.5). Compared to reference group, 5G allele irrespective of FVL was associated with lower risk of VTE recurrence only when compared with 4G allele together with FVL. In conclusion, FVL has a modifying effect on PAI-1 polymorphism in relation to risk of VTE recurrence. The role of PAI-1 polymorphism as a risk factor of recurrent VTE may be FVL dependent.

    Although the prothrombin G20210A mutation has been implicated as a risk factor for venous thrombosis, its role in arterial ischemic stroke is unclear, particularly among young adults. To address this issue, we examined the association between prothrombin G20210A and ischemic stroke in a white case-control population and additionally performed a meta-analysis. From the population-based Genetics of Early Onset Stroke (GEOS) study, we identified 397 individuals of European ancestry aged 15 to 49 years with first-ever ischemic stroke and 426 matched controls. Logistic regression was used to calculate odds ratios (ORs) in the entire population and for subgroups stratified by sex, age, oral contraceptive use, migraine, and smoking status. A meta-analysis of 17 case-control studies (n=2305 cases ischemic stroke did not achieve statistical significance (OR=2.5; 95% confidence interval [CI]=0.9-6.5; P=0.07). However, among adults aged 15 to 42 years (younger than median age), cases were significantly more likely than controls to have the mutation (OR=5.9; 95% CI=1.2-28.1; P=0.03), whereas adults aged 42 to 49 years were not (OR=1.4; 95% CI=0.4-5.1; P=0.94). In our meta-analysis, the mutation was associated with significantly increased stroke risk in adults ≤55 years (OR=1.4; 95% CI=1.1-1.9; P=0.02), with significance increasing with addition of the GEOS results (OR=1.5; 95% CI=1.1-2.0; P=0.005). The prothrombin G20210A mutation is associated with ischemic stroke in young adults and may have an even stronger association among those with earlier onset strokes. Our finding of a stronger association in the younger young adult population requires replication.

A total of 105 children were included in this cross-sectional study. Patients were divided into two groups. The study group consisted of 55 infants with a history of ROP and the control group comprised 50 healthy infants with term birth. All subjects were screened for the presence of certain mutations (FVL, Prothrombin G20210A, MTHFR C677T and MTHFR A1298C) by Real-Time PCR at 1 year of age. The mean gestational age (GA) and birth weight (BW) of the study group were, 28.65 ± 2.85 weeks and 1171 ± 385.74 g, respectively. There were no significant differences of genotype and allele frequency of Prothrombin G20210A, MTHFR A1298C and MTHFR C677T between the study and control groups (p > 0.05). Eight children (14.5 %) had heterozygous and one child (1.8%) had homozygous FVL mutation in the study group. One child (2%) in the control group had heterozygous FVL mutation. There was statistically significant differences of FVL allele and genotype frequencies between the groups (p < 0.05). The prevalence of FVL polymorphism (16.3 %) was higher in ROP patients than control subjects in this Turkish cohort. We suggest a possible association of FVL mutation with ROP at the end of the study.

    Prothrombin time (PT) is clinically important and is used to monitor oral anticoagulant therapy. To obtain PT results in international normalized ratio (INR), the current standardization procedure is complex and involves reference reagents. The PT of diluted plasma samples can be determined with a combined thromboplastin (the Owren-type procedure), but not necessarily with a plain thromboplastin (the Quick-type procedure). Owren-type PT procedures can therefore, as an alternative to the INR calibration, be calibrated with diluted normal plasma to give PT results in percent of normal PT activity (PT%). The present study explored if a plasma-based calibration of an Owren-type PT procedure can be used to obtain results in INR. The approach was to establish a relationship between PT% and INR by multi-center analysis of 365 samples from healthy individuals and patients on warfarin treatment. INR values were obtained by manual Quick-type reference procedure and PT% values by various automated Owren-type procedures. A relationship INR = (1/PT% + 0.018)/0.028 was found. A calibration procedure, based on the relationship, was investigated. Calibrators were the median PT of 21 normal plasma at dilutions representing 100%, 50%, 25%, 12.5% and 6.25% of normal PT activity. These were assigned INR values of 1.00, 1.36, 2.07, 3.05 and 6.36. Calibration of various Owren-type assays was repeatedly performed by 5 expert laboratories during 3 consecutive years. The INR values of certain lyophilised or frozen control plasmas were determined. The frozen control plasmas had externally assigned INR values according to WHO guide-lines. Within the laboratory, CV was typically below 3%. No appreciable difference among the results of the different laboratories or the three assay occasions was found. Externally assigned and INR values were essentially identical to those found. These and other results indicated that the calibration procedure was reproducible, precise and accurate. Thus, an

    Objectives Antibodies to phosphatidylserine/prothrombin complex (aPS/PT) detectable in sera of some patients with antiphospholipid syndrome (APS) have been shown to correlate with thrombosis. However, associations of aPS/PT antibodies with APS related disorders remain unclear. Aim To evaluate whether there are any associations between aPS/PT antibodies and Raynaud phenomenon, migraine and/or valvular lesions in primary thrombotic APS (PAPS). Methods We enrolled 67 consecutive patients (56 women) with thrombotic PAPS (VTE in 80.6%), aged 46.2 ± 13.5 years. The exclusion criteria were: acute coronary syndromes or stroke within preceding 6 months, cancer, severe comorbidities and pregnancy. The IgG and IgM aPS/PT antibodies were determined by ELISA with the cut-off of 30 units. We recorded Raynaud phenomenon, migraine and valvular lesions. Results Positive IgM or/and IgG aPS/PT antibodies were observed in 29 patients (43.3%), with a higher prevalence of IgM antibodies ( n = 27, 40.3%) compared with IgG isotype ( n = 12, 17.9%, p = 0.014). aPS/PT antibodies were observed most commonly in patients with triple aPL ( n = 12, 85.7%) compared with those with double ( n = 5, 35.7%) or single aPL antibodies (n = 12, 30.8%, p = 0.03), with no association with demographics, the ANA titre, the type of thrombotic events or medications. Raynaud phenomenon, migraine and valvular lesions were observed in 15% ( n = 10), 30% ( n = 20) and 18% ( n = 12) of the patients, respectively. Raynaud phenomenon and migraine, but not valvular lesions, were markedly more frequent in PAPS patients presenting with positive aPS/PT antibodies ( n = 10, 34.5% vs. n = 0, 0%; p = 0.0001). Conclusions In PAPS patients aPS/PT antibodies are related to the occurrence of both Raynaud phenomenon and migraine.

    Increasing evidence has highlighted the role of non-criteria antiphospholipid antibodies (aPLs) as important supplements to the current criteria aPLs for the diagnosis of antiphospholipid syndrome (APS). In this retrospective study, we evaluated the clinical relevance of antibodies to phosphatidylserine/prothrombin (aPS/PT) in Chinese patients with APS. A total of 441 subjects were tested, including 101 patients with primary APS (PAPS), 140 patients with secondary APS (SAPS), 161 disease controls (DCs) and 39 healthy controls (HCs). Serum IgG/IgM aPS/PT was determined by ELISA. The levels of IgG/IgM aPS/PT were significantly increased in patients with APS compared with DCs and HCs. IgG and IgM aPS/PT were present in 29.7% and 54.5% of PAPS, and 42.1% and 53.6% of SAPS, respectively. For diagnosis of APS, IgG aCL exhibited the highest positive likelihood ratio (LR+) of 21.60, followed by LA (13.84), IgG aβ2GP1 (9.19) and IgG aPS/PT (8.49). aPS/PT was detected in 13.3% of seronegative PAPS patients and 31.3% of seronegative SAPS patients. LA exhibited the highest OR of 3.64 in identifying patients with thrombosis, followed by IgG aCL (OR, 2.63), IgG aPS/PT (OR, 2.55) and IgG aβ2GP1 (OR, 2.33). LA and IgG aCL were correlated with both arterial and venous thrombosis, whereas IgG aPS/PT and IgG aβ2GP1 correlated with venous or arterial thrombosis, respectively. Our findings suggest that the inclusion of IgG/IgM aPS/PT may enhance the diagnostic performance for APS, especially in those in whom APS is highly suspected, but conventional aPLs are repeatedly negative. In addition, IgG aPS/PT may contribute to identify patients at risk of thrombosis.

    Full Text Available Life-threatening bleeding in anticoagulation with Warfarin is an emergency challenging issue. Several approaches are available to treat bleeding in either over-anticoagulation or propeanticoagulation, including vitamin K, fresh frozen plasma and prothrombin complex concentrates (PCC administration. In coexisting trauma-induced bleeding and anticoagulation, reversal of anticoagulation must be a rapid and highly effective procedure. Furthermore the appropriate treatment must be directly available in each shock rooms to guarantee the rapid management of the emergency. PCC require a simple storage, rapid accessibility, fast administration procedures and high effectiveness. Here we report the utility of PCC in management of a craniofacial trauma in proper-anticoagulation.

    Atomistic molecular dynamics simulation is a promising technique to investigate the energetics and dynamics in the protein-surface adsorption process which is of high relevance to modern biotechnological applications. To increase the chance of success in simulating the adsorption process, favorable orientations of the protein at the surface must be determined. Here, we present ProtPOS which is a lightweight and easy-to-use python package that can predict low-energy protein orientations on a surface of interest. It combines a fast conformational sampling algorithm with the energy calculation of GROMACS. The advantage of ProtPOS is it allows users to select any force fields suitable for the system at hand and provide structural output readily available for further simulation studies. ProtPOS is freely available for academic and non-profit uses at http://cbbio.cis.umac.mo/software/protpos Supplementary data are available at Bioinformatics online. shirleysiu@umac.mo. © The Author 2016.

    There is great interest in increasing proteins' stability to enhance their utility as biocatalysts, therapeutics, diagnostics and nanomaterials. Directed evolution is a powerful, but experimentally strenuous approach. Computational methods offer attractive alternatives. However, due to the limited reliability of predictions and potentially antagonistic effects of substitutions, only single-point mutations are usually predicted in silico, experimentally verified and then recombined in multiple-point mutants. Thus, substantial screening is still required. Here we present FireProt, a robust computational strategy for predicting highly stable multiple-point mutants that combines energy- and evolution-based approaches with smart filtering to identify additive stabilizing mutations. FireProt's reliability and applicability was demonstrated by validating its predictions against 656 mutations from the ProTherm database. We demonstrate that thermostability of the model enzymes haloalkane dehalogenase DhaA and γ-hexachlorocyclohexane dehydrochlorinase LinA can be substantially increased (ΔTm = 24°C and 21°C) by constructing and characterizing only a handful of multiple-point mutants. FireProt can be applied to any protein for which a tertiary structure and homologous sequences are available, and will facilitate the rapid development of robust proteins for biomedical and biotechnological applications.

    To define the characteristics of effective mentor-protégé relationships in a Clinical Research Training Program (CRTP) and to assess the agreement among mentors and protégés regarding those attributes. The authors administered an anonymous survey to protégés who completed the Albert Einstein College of Medicine's CRTP during its first seven years (2000-2006) and their mentors. Statements included aspects of mentoring thought to be important within the program, such as availability (Statement 1) and oversight of the thesis process (Statements 2-4). Additional statements were related both to career development (e.g., looking out for the best interests of the scholar and assisting in negotiations for a faculty position after program completion [Statements 5 and 6]) and to the expectation that the mentor would continue to be a resource for the protégé in years to come (Statement 7). The authors assessed overall agreement among mentors and protégés, using matched pair analysis. Overall response was 70.7% (133/188), with fewer matched pairs (n = 50, 50%). Seventy-five percent of respondents agreed strongly or somewhat with all statements. Analysis indicated significant agreement with Statements 2, 4, 6, and 7. Median scores from protégés did not differ whether their mentor responded (paired) or not (unpaired); however, mentor-protégé pairs had significantly greater agreement with Statements 3-7 than unpaired mentors and protégés (P Mentors and protégés seemed to agree that mentors within a CRTP demonstrated effective mentor attributes, including fostering a long-term relationship with the protégé.

    Pseutarin C is a group C prothrombin activator from the venom of the eastern brown snake Pseudonaja textilis. It is a multi-subunit protein complex consisting of catalytic and nonenzymatic subunits similar to coagulation factor Xa and factor Va, respectively. Here we describe the complete sequence of the nonenzymatic subunit. Based on the partial amino acid sequence of the nonenzymatic subunit, degenerate primers were designed. Using a "walking" strategy based on sequentially designed primers, we determined the complete cDNA sequence of the nonenzymatic subunit. The cDNA encodes a protein of 1461 amino acid residues, which includes a 30-residue signal peptide, a mature protein of 1430 amino acid residues, and a stop codon. cDNA blot analysis showed a single transcript of approximately 4.6 kb. The deduced amino acid sequence shows approximately 50% identity to mammalian factor V and by homology has a similar domain structure consisting of domains A1-A2-B-A3-C1-C2. Interestingly, the B domain of pseutarin C is shorter than that of mammalian factor V (FV). Although most of the proteolytic activation sites are conserved, 2 of 3 proteolytic sites cleaved by activated protein C are mutated, and thus activated protein C is not able to inactivate this procoagulant toxin. The predicted posttranslational modifications, including disulfide bonds, N-glycosylation, phosphorylation, and sulfation, in pseutarin C are significantly different compared with bovine factor V. Thus, our data demonstrate that the nonenzymatic subunit of group C prothrombin activators is structurally similar to mammalian FV.

    Background and Purpose Although the prothrombin G20210A mutation has been implicated as a risk factor for venous thrombosis, its role in arterial ischemic stroke is unclear, particularly among young-adults. To address this issue, we examined the association between prothrombin G20210A and ischemic stroke in a Caucasian case-control population and additionally performed a meta-analysis Methods From the population-based Genetics of Early Onset Stroke (GEOS) study we identified 397 individuals of European ancestry aged 15-49 years with first-ever ischemic stroke and 426 matched-controls. Logistic regression was used to calculate odds ratios in the entire population and for subgroups stratified by gender, age, oral contraceptive use, migraine and smoking status. A meta-analysis of 17 case-control studies (n=2305 cases ischemic stroke did not achieve statistical significance (OR=2.5,95%CI=0.9-6.5,p=0.07). However, among adults aged 15-42 (younger than median age), cases were significantly more likely than controls to have the mutation (OR=5.9,95%CI=1.2-28.1,p=0.03), whereas adults ages 42-49 were not (OR=1.4,95%CI=0.4-5.1,p=0.94). In our meta-analysis, the mutation was associated with significantly increased stroke risk in adults ischemic stroke in young-adults and may have an even stronger association among those with earlier onset strokes. Our finding of a stronger association in the younger-young adult population requires replication. PMID:24619398

    The widening gap between known proteins and their functions has encouraged the development of methods to automatically infer annotations. Automatic functional annotation of proteins is expected to meet the conflicting requirements of maximizing annotation coverage, while minimizing erroneous functional assignments. This trade-off imposes a great challenge in designing intelligent systems to tackle the problem of automatic protein annotation. In this work, we present a system that utilizes rule mining techniques to predict metabolic pathways in prokaryotes. The resulting knowledge represents predictive models that assign pathway involvement to UniProtKB entries. We carried out an evaluation study of our system performance using cross-validation technique. We found that it achieved very promising results in pathway identification with an F1-measure of 0.982 and an AUC of 0.987. Our prediction models were then successfully applied to 6.2 million UniProtKB/TrEMBL reference proteome entries of prokaryotes. As a result, 663,724 entries were covered, where 436,510 of them lacked any previous pathway annotations.

  11. Teachable Agents and the Protégé Effect: Increasing the Effort Towards Learning

    2009-08-01

    Betty's Brain is a computer-based learning environment that capitalizes on the social aspects of learning. In Betty's Brain, students instruct a character called a Teachable Agent (TA) which can reason based on how it is taught. Two studies demonstrate the protégé effect: students make greater effort to learn for their TAs than they do for themselves. The first study involved 8th-grade students learning biology. Although all students worked with the same Betty's Brain software, students in the TA condition believed they were teaching their TAs, while in another condition, they believed they were learning for themselves. TA students spent more time on learning activities (e.g., reading) and also learned more. These beneficial effects were most pronounced for lower achieving children. The second study used a verbal protocol with 5th-grade students to determine the possible causes of the protégé effect. As before, students learned either for their TAs or for themselves. Like study 1, students in the TA condition spent more time on learning activities. These children treated their TAs socially by attributing mental states and responsibility to them. They were also more likely to acknowledge errors by displaying negative affect and making attributions for the causes of failures. Perhaps having a TA invokes a sense of responsibility that motivates learning, provides an environment in which knowledge can be improved through revision, and protects students' egos from the psychological ramifications of failure.

    The analysis of high-throughput mass spectrometry-based proteomics data must address the specific challenges of this technology. To this end, the comprehensive proteomics workflow offered by the de.NBI service center BioInfra.Prot provides indispensable components for the computational and statistical analysis of this kind of data. These components include tools and methods for spectrum identification and protein inference, protein quantification, expression analysis as well as data standardization and data publication. All particular methods of the workflow which address these tasks are state-of-the-art or cutting edge. As has been shown in previous publications, each of these methods is adequate to solve its specific task and gives competitive results. However, the methods included in the workflow are continuously reviewed, updated and improved to adapt to new scientific developments. All of these particular components and methods are available as stand-alone BioInfra.Prot services or as a complete workflow. Since BioInfra.Prot provides manifold fast communication channels to get access to all components of the workflow (e.g., via the BioInfra.Prot ticket system: bioinfraprot@rub.de) users can easily benefit from this service and get support by experts.

    The increasing incidence of hepatocellular carcinoma (HCC) in Western countries requests reliable tumour markers for preclinical diagnosis. We evaluated the diagnostic accuracy of des-gamma-carboxy prothrombin (DCP), in comparison with alpha-fetoprotein (AFP) in a French cohort using a new analyser. One hundred and sixty-two patients with virus-related cirrhosis (46 HCC patients and 116 controls) were recruited in this retrospective proof-of-concept study. DCP was measured on new Lumipulse ® G600 analyzer and AFP on usual Cobas e602 analyzer in serum samples that were collected at the time of HCC diagnosis for HCC patients or during follow-up for controls. DCP and AFP levels were higher in HCC patients. The area under receiver operating characteristic curve was larger for DCP than for AFP (0.89 vs 0.77, P=.03). At the cut-off value of 128 mAU/mL, sensitivity and specificity for DCP were 74% and 92%. At the cut-off value of 20 μg/L, sensitivity and specificity for AFP were 63% and 82%. NRI >0 for the association of "AFP+DCP" were 101%, P<.0001, and 23%, P=.03, compared to "AFP" or "DCP" alone, respectively. We conclude that DCP outperformed AFP for the detection of HCC. © 2016 John Wiley & Sons Ltd.

    Aim To investigate association of factor V Leiden, prothrombin G20210A, MTHFR C677T and PAI-1 4G/5G polymorphisms with recurrent pregnancy loss in Bosnian women. Methods A total of 60 women with two or more consecutive miscarriages before 20 weeks of gestation with the same partners and without history of known causes or recurrent pregnancy loss were included. A control group included 80 healthy women who had one or more successful pregnancies without history of any complication which could be associated with miscarriages. Genotyping of factor V Leiden, prothrombin G20210A, MTHFR C677T and PAI-1 4G/5G polymorphisms were performed by polymerase chain reaction/restriction fragments length polymorphism method (PCR/RFLP). Results Both factor V Leiden and MTHFR C677T polymorphisms were significantly associated with recurrent pregnancy loss (RPL) in Bosnian women while prothrombin G20210A and PAI-1 4G/5G polymorphisms did not show strongly significant association. Conclusion The presence of thrombophilic polymorphisms may predispose women to recurrent pregnancy loss. Future investigation should be addressed in order to find when carriers of those mutations, polymorphisms should be treated with anticoagulant therapy.

    For many years, an area of research in higher education has been emerging around the development and implementation of fair and effective peer evaluation programs. Recently, a new body of knowledge has developed regarding the development and implementation of fair and effective peer evaluation programs resulting in formative and summative evaluations. The purpose of this article is to describe the development, implementation, and evaluation of a peer review of teaching (PRoT) program for nursing faculty, initiated at one small comprehensive university in the northeastern United States. Pairs of nursing faculty evaluated each other's teaching, syllabi, and course materials after collaborating in a pre-evaluation conference to discuss goals of the classroom visit. Qualitative data gathered in post project focus groups revealed that faculty found their modified PRoT process to be a mutually beneficial experience that was more useful, flexible and collegial, and less stressful than their previous evaluation process.

    Full Text Available Semantic web is a technology that allows us to build a knowledge base or ontology for the information of the web page can be understood by computers. One software for building ontology-based semantic web is a protégé. Protege allows developers to develop an ontology with an expression of logic description. Protégé provides a plugin such as DL-Query and SPARQL-Query to display information that involve expression of class, property and individual in the ontology. The problem that then arises is DL-plugin Query only able to process the rules that involve expression of class to any object property, despite being equipped with the function of reasoning. while the SPARQL-Query plugin does not have reasoning abilities such as DL-Query plugin although the SPARQL-Query plugin can query memperoses rules involving class, property and individual. This research resulted in a new plugin using SPARQL-DL with input natural language as a protégé not provide a plugin with input natural language to see results from the combined expression-expression contained in the ontology that allows developers to view information ontology language that is easier to understand without having think of SPARQL query structure is complicated.

    The exponential growth of protein structural and sequence databases is enabling multifaceted approaches to understanding the long sought sequence-structure-function relationship. Advances in computation now make it possible to apply well-established data mining and pattern recognition techniques to these data to learn models that effectively relate structure and function. However, extracting meaningful numerical descriptors of protein sequence and structure is a key issue that requires an efficient and widely available solution. We here introduce ProtDCal, a new computational software suite capable of generating tens of thousands of features considering both sequence-based and 3D-structural descriptors. We demonstrate, by means of principle component analysis and Shannon entropy tests, how ProtDCal's sequence-based descriptors provide new and more relevant information not encoded by currently available servers for sequence-based protein feature generation. The wide diversity of the 3D-structure-based features generated by ProtDCal is shown to provide additional complementary information and effectively completes its general protein encoding capability. As demonstration of the utility of ProtDCal's features, prediction models of N-linked glycosylation sites are trained and evaluated. Classification performance compares favourably with that of contemporary predictors of N-linked glycosylation sites, in spite of not using domain-specific features as input information. ProtDCal provides a friendly and cross-platform graphical user interface, developed in the Java programming language and is freely available at: http://bioinf.sce.carleton.ca/ProtDCal/ . ProtDCal introduces local and group-based encoding which enhances the diversity of the information captured by the computed features. Furthermore, we have shown that adding structure-based descriptors contributes non-redundant additional information to the features-based characterization of polypeptide systems. This

Diversos aspectos funcionais associam-se a estes fatores representados pela oclusão, dimensão vertical, retenção, estabilidade dinâmica e estática além de aspectos qualitativos relacionados às condições encontradas no desdentado. Foram levados em consideração o período de edentulismo, número e tempo de uso das próteses, uso contínuo, conservação, presença de placa e higiene bucal. Os fatores foram avaliados, visando esclarecer a possível relação dos aspectos funcionais e protéticos com a EP. Exame clínico foi realizado em 116 pacientes de ambos os sexos, desdentados bimaxilares, que utilizavam as duas próteses muco-suportadas, portadores ou não de estomatite protética (EP. Os resultados indicaram que a maioria dos pacientes examinados tinha EP frente ao menor número de pacientes sem EP, havendo nos dois grupos equivalência nos resultados da avaliação clínica e protética. Os fatores funcionais e qualitativos das próteses, avaliados isoladamente, não puderam ser considerados responsáveis pela ocorrência dessa patologia, constatando-se que um único fator protético não demonstrou, de per si, ser responsável pela presença da EP, embora possa ser um facilitador para o seu desenvolvimento.

    Although policy providers have outlined minimal metadata guidelines and naming conventions, ontologies of today still display inter- and intra-ontology heterogeneities in class labelling schemes and metadata completeness. This fact is at least partially due to missing or inappropriate tools. Software support can ease this situation and contribute to overall ontology consistency and quality by helping to enforce such conventions. We provide a plugin for the Protégé Ontology editor to allow for easy checks on compliance towards ontology naming conventions and metadata completeness, as well as curation in case of found violations. In a requirement analysis, derived from a prior standardization approach carried out within the OBO Foundry, we investigate the needed capabilities for software tools to check, curate and maintain class naming conventions. A Protégé tab plugin was implemented accordingly using the Protégé 4.1 libraries. The plugin was tested on six different ontologies. Based on these test results, the plugin could be refined, also by the integration of new functionalities. The new Protégé plugin, OntoCheck, allows for ontology tests to be carried out on OWL ontologies. In particular the OntoCheck plugin helps to clean up an ontology with regard to lexical heterogeneity, i.e. enforcing naming conventions and metadata completeness, meeting most of the requirements outlined for such a tool. Found test violations can be corrected to foster consistency in entity naming and meta-annotation within an artefact. Once specified, check constraints like name patterns can be stored and exchanged for later re-use. Here we describe a first version of the software, illustrate its capabilities and use within running ontology development efforts and briefly outline improvements resulting from its application. Further, we discuss OntoChecks capabilities in the context of related tools and highlight potential future expansions. The OntoCheck plugin facilitates

    Prior studies suggest patient self-testing (PST) of prothrombin time (PT) can improve the quality of anticoagulation (AC) and reduce complications (e.g., bleeding and thromboembolic events). "The Home INR Study" (THINRS) compared AC management with frequent PST using a home monitoring device to high-quality AC management (HQACM) with clinic-based monitoring on major health outcomes. A key clinical and policy question is whether and which patients can successfully use such devices. We report the results of Part 1 of THINRS in which patients and caregivers were evaluated for their ability to perform PST. Study-eligible patients (n = 3643) were trained to use the home monitoring device and evaluated after 2-4 weeks for PST competency. Information about demographics, medical history, warfarin use, medications, plus measures of numeracy, literacy, cognition, dexterity, and satisfaction with AC were collected. Approximately 80% (2931 of 3643) of patients trained on PST demonstrated competency; of these, 8% (238) required caregiver assistance. Testers who were not competent to perform PST had higher numbers of practice attempts, higher cuvette wastage, and were less able to perform a fingerstick or obtain blood for the cuvette in a timely fashion. Factors associated with failure to pass PST training included increased age, previous stroke history, poor cognition, and poor manual dexterity. A majority of patients were able to perform PST. Successful home monitoring of PT with a PST device required adequate levels of cognition and manual dexterity. Training a caregiver modestly increased the proportion of patients who can perform PST.

    Congenital factor VII deficiency is a rare bleeding disorder with high phenotypic variability. It is critical that children with congenital Factor VII deficiency be identified early when high-risk surgery is planned. Cranial vault surgery is common for children with craniosynostosis, and these surgeries are associated with significant morbidity mostly secondary to the risk of massive blood loss. A two-month old infant who presented for elective craniosynostosis repair was noted to have an elevated prothrombin time (PT) with a normal activated partial thromboplastin time (aPTT) on preoperative labs. The infant had no clinical history or reported family history of bleeding disorders, therefore a multidisciplinary decision was made to repeat the labs under general anesthesia and await the results prior to incision. The results confirmed the abnormal PT and the case was canceled. Hematologic workup during admission revealed factor VII deficiency. The patient underwent an uneventful endoscopic strip craniectomy with perioperative administration of recombinant Factor VIIa. Important considerations for perioperative laboratory evaluation and management in children with factor VII deficiency are discussed. Anesthetic and surgical management of the child with factor VII deficiency necessitates meticulous planning to prevent life threatening bleeding during the perioperative period. A thorough history and physical examination with a high clinical suspicion are vital in preventing hemorrhage during surgeries in children with coagulopathies. Abnormal preoperative lab values should always be confirmed and addressed before proceeding with high-risk surgery. A multidisciplinary discussion is essential to optimize the risk-benefit ratio during the perioperative period. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

    A hallmark feature of antiphospholipid syndrome (APS) is the presence of a wide spectrum of antiphospholipid antibodies. In this study, we evaluated the clinical relevance of antibodies to prothrombin (PT) (aPT) and thrombin (aThr) in Chinese patients with APS. A total of 229 subjects were tested, including 86 patients with APS [35 patients with primary APS (PAPS), 51 patients with APS associated with other diseases (APSAOD)], 104 patients with non-APS diseases (disease controls), and 39 healthy controls. Serum IgG/IgM/IgA aPT and aThr were determined by ELISA. The levels of both IgG/IgM/IgA aPT and IgG/IgM/IgA aThr were significantly increased in patients with PAPS and APSAOD compared with patients with non-APS thrombosis and non-APS PRM, and HC. Both IgG aPT and IgG aThr exhibited promising diagnostic potentials for APS with sensitivities and specificities of 16.3 and 95.8% (IgG aPT), and 19.8 and 99.3% (IgG aThr), respectively. Importantly, both IgG aPT (OR 4.06; 95% CI 1.49-11.05) and IgG aThr (OR 4.49; 95% CI 1.62-12.45) were significantly correlated with arterial, but not venous, thrombotic events. Our findings highlighted that IgG aPT and IgG aThr could serve as promising biomarkers to identify patients at risk of arterial thrombosis in China.

    Reversal of therapeutic anticoagulation prior to emergency neurosurgical procedures is required in the setting of intracranial hemorrhage. Multifactor prothrombin complex concentrate (PCC) promises rapid efficacy but may increase the probability of thrombotic complications compared to fresh frozen plasma (FFP). To compare the rate of thrombotic complications in patients treated with PCC or FFP to reverse therapeutic anticoagulation prior to emergency neurosurgical procedures in the setting of intracranial hemorrhage at a level I trauma center. Sixty-three consecutive patients on warfarin therapy presenting with intracranial hemorrhage who received anticoagulation reversal prior to emergency neurosurgical procedures were retrospectively identified between 2007 and 2016. They were divided into 2 cohorts based on reversal agent, either PCC (n = 28) or FFP (n = 35). The thrombotic complications rates within 72 h of reversal were compared using the χ 2 test. A multivariate propensity score matching analysis was used to limit the threat to interval validity from selection bias arising from differences in demographics, laboratory values, history, and clinical status. Thrombotic complications were uncommon in this neurosurgical population, occurring in 1.59% (1/63) of treated patients. There was no significant difference in the thrombotic complication rate between groups, 3.57% (1/28; PCC group) vs 0% (0/35; FFP group). Propensity score matching analysis validated this finding after controlling for any selection bias. In this limited sample, thrombotic complication rates were similar between use of PCC and FFP for anticoagulation reversal in the management of intracranial hemorrhage prior to emergency neurosurgical procedures.

    2013-05-11

    Ambiguity in texts is a well-known problem: words can carry several meanings, and hence, can be read and interpreted differently. This is also true in the biological literature; names of biological concepts, such as genes and proteins, might be ambiguous, referring in some cases to more than one gene or one protein, or in others, to both genes and proteins at the same time. Public biological databases give a very useful insight about genes and proteins information, including their names. In this study, we made a thorough analysis of the nomenclatures of genes and proteins in two data sources and for six different species. We developed an automated process that parses, extracts, processes and stores information available in two major biological databases: Entrez Gene and UniProtKB. We analysed gene and protein synonyms, their types, frequencies, and the ambiguities within a species, in between data sources and cross-species. We found that at least 40% of the cross-species ambiguities are caused by names that are already ambiguous within the species. Our study shows that from the six species we analysed (Homo Sapiens, Mus Musculus, Arabidopsis Thaliana, Oryza Sativa, Bacillus Subtilis and Pseudomonas Fluorescens), rice (Oriza Sativa) has the best naming model in Entrez Gene database, with low ambiguities between data sources and cross-species.

    To investigate parameters associated with hematoma enlargement in non-vitamin K antagonist oral anticoagulant (NOAC)-related intracerebral hemorrhage (ICH). This retrospective cohort study includes individual patient data for 190 patients with NOAC-associated ICH over a 5-year period (2011-2015) at 19 departments of neurology across Germany. Primary outcome was the association of prothrombin complex concentrate (PCC) administration with hematoma enlargement. Subanalyses were calculated for blood pressure management and its association with the primary outcome. Secondary outcomes include associations with in-hospital mortality and functional outcome at 3 months assessed using the modified Rankin Scale. The study population for analysis of primary and secondary outcomes consisted of 146 NOAC-ICH patients with available follow-up imaging. Hematoma enlargement occurred in 49/146 (33.6%) patients with NOAC-related ICH. Parameters associated with hematoma enlargement were blood pressure ≥ 160mmHg within 4 hours and-in the case of factor Xa inhibitor ICH-anti-Xa levels on admission. PCC administration prior to follow-up imaging was not significantly associated with a reduced rate of hematoma enlargement either in overall NOAC-related ICH or in patients with factor Xa inhibitor intake (NOAC: risk ratio [RR] = 1.150, 95% confidence interval [CI] = 0.632-2.090; factor Xa inhibitor: RR = 1.057, 95% CI = 0.565-1.977), regardless of PCC dosage given or time interval until imaging or treatment. Systolic blood pressure levels < 160mmHg within 4 hours after admission were significantly associated with a reduction in the proportion of patients with hematoma enlargement (RR = 0.598, 95% CI = 0.365-0.978). PCC administration had no effect on mortality and functional outcome either at discharge or at 3 months. In contrast to blood pressure control, PCC administration was not associated with a reduced rate of hematoma enlargement in NOAC-related ICH

    The aim of the study was to determine the prevalence and clinical associations of antiphosphatidylserine/prothrombin antibodies (aPS/PT) with thrombosis and pregnancy loss in Chinese patients with antiphospholipid syndrome (APS) and seronegative APS (SNAPS). One hundred and eighty six Chinese patients with APS (67 primary, 119 secondary), 48 with SNAPS, 176 disease controls (79 systemic lupus erythematosus [SLE], 29 Sjogren's syndrome [SS], 30 ankylosing spondylitis [AS], 38 rheumatoid arthritis [RA]) and 90 healthy donors were examined. IgG and IgM aPS/PT, IgG/IgM/IgA anticardiolipin (aCL) and IgG/IgM/IgA anti-β2-glycoprotein I (anti-β2GPI) antibodies were tested by ELISA. One hundred and sixty (86.0%) of APS patients were positive for at least one aPS/PT isotype. One hundred and thirty five (72.6%) were positive for IgG aPS/PT, 124/186 (66.7%) positive for IgM aPS/PT and 99 (53.2%) positive for both. Approximately half of the SNAPS patients were positive for IgG and/or IgM aPS/PT. Highly significant associations between IgG aPS/PT and venous thrombotic events (odds ratio [OR]=6.72) and IgG/IgM aPS/PT and pregnancy loss (OR=9.44) were found. Levels of IgM aPS/PT were significantly different in APS patients with thrombotic manifestations and those with fetal loss (p=0.014). The association between IgG/IgM aPS/PT and lupus anticoagulant (LAC) was highly significant (pAPS was 101.6. Notably, 91.95% (80/87) of LAC-positive specimens were positive for IgG and/or IgM aPS/PT, suggesting aPS/PT is an effective option when LAC testing is not available. Anti-PS/PT antibody assays demonstrated high diagnostic performance for Chinese patients with APS, detected some APS patients negative for criteria markers and may serve as potential risk predictors for venous thrombosis and obstetric complications.

    Full Text Available ObjectiveTo investigate the correlation between HBsAg, prothrombin time activity (PTA, and indocyanine green retention rate at 15 minutes (ICG R15 in patients with HBeAg-positive chronic HBV infection. MethodsA total of 92 patients with HBeAg-positive chronic HBV infection who were admitted to The First Hospital of Lanzhou University from December 2015 to April 2016 were enrolled and divided into chronic hepatitis B (CHB group (24 patients, compensated liver cirrhosis group (38 patients, and decompensated liver cirrhosis group (30 patients. Serum HBsAg quantitation, PTA test, and liver reserve function test (ICG R15 were performed for all patients. The chi-square test was used for comparison of categorical data between groups, an analysis of variance was used for comparison of continuous data between multiple groups, and a Pearson correlation analysis was also performed. ResultsThere were significant differences between the three groups in serum HBsAg quantitation (3.82±0.43 log10IU/ml vs 2.88±0.36 log10IU/ml vs 2.60±0.27 log10IU/ml, F=25.19, P<0.001, ICG R15 (7.51%±3.10% vs 9.57%±8.18% vs 24.13%±14.28%, F=24.00, P=0.001, and PTA (8100%±1762% vs 83.08%±9.64% vs 62.32%±16.90%, F=13.42, P=0.009. The correlation analysis showed that PTA was negatively correlated with ICG R15 in all three groups (r=-0.948, -0.602, and -0.735, all P<0.01. In the compensated liver cirrhosis group and decompensated liver cirrhosis group, HBsAg was positively correlated with PTA (r=0.410 and 0.473, both P<0.05 and negatively correlated with ICG R15 (r=-0.427 and -0.768, P<0.01. ConclusionIn HBeAg positive patients, there are certain correlations between HBsAg, PTA, and ICG R15, which, to a certain degree, reflects the liver reserve function in patients with chronic HBV infection.

    Full Text Available Uma das dificuldades na difusão de tecnologias de construção não convencionais é a ausência de informações técnicas sobre os sistemas construtivos existentes. Exemplos de construção eco-eficiente, em pequena escala, feita com blocos de terra crua, desenvolvidos pelo Prof. Roberto Mattone, do Politecnico di Torino, Itália, podem ser encontrados no Brasil, Itália e Argentina. Estes blocos feitos com prensa manual apresentam intertravamentos entre si que melhoram a resistência e a rigidez da alvenaria. Testes em protótipos construídos com eles são necessários para atender as exigências técnicas e se obter credibilidade nas agências governamentais financiadoras. Este artigo apresenta resultados referentes a avaliação de desempenho estrutural de alvenaria (protótipo construído em escala real feita com blocos de terra crua estabilizada, mecânicamente por prensagem e químicamente por adição de cimento Portland. As avaliações de cargas de ocupação e impactos na alvenaria foram realizadas através de ensaios de impactos de corpo mole e de corpo duro, solicitações transmitidas por fechamentos bruscos de porta e solicitações de cargas provenientes de peças suspensas. A partir dos resultados pode-se afirmar que o protótipo apresentou desempenho satisfatório em relação à segurança estrutural. Destaca-se que os blocos avaliados tem grande potencial para reduzir o impacto ambiental das edificações.

    Millions of life scientists across the world rely on bioinformatics data resources for their research projects. Data resources can be very expensive, especially those with a high added value as the expert-curated knowledgebases. Despite the increasing need for such highly accurate and reliable sources of scientific information, most of them do not have secured funding over the near future and often depend on short-term grants that are much shorter than their planning horizon. Additionally, they are often evaluated as research projects rather than as research infrastructure components. In this work, twelve funding models for data resources are described and applied on the case study of the Universal Protein Resource (UniProt), a key resource for protein sequences and functional information knowledge. We show that most of the models present inconsistencies with open access or equity policies, and that while some models do not allow to cover the total costs, they could potentially be used as a complementary income source. We propose the Infrastructure Model as a sustainable and equitable model for all core data resources in the life sciences. With this model, funding agencies would set aside a fixed percentage of their research grant volumes, which would subsequently be redistributed to core data resources according to well-defined selection criteria. This model, compatible with the principles of open science, is in agreement with several international initiatives such as the Human Frontiers Science Program Organisation (HFSPO) and the OECD Global Science Forum (GSF) project. Here, we have estimated that less than 1% of the total amount dedicated to research grants in the life sciences would be sufficient to cover the costs of the core data resources worldwide, including both knowledgebases and deposition databases.

    2017-01-01

    Full Text Available This article discusses the careers of Lucius Septimius Petronianus and Tiberius Claudius Proculus Cornelianus, who successively held the post of procurator of the mining districts situated in the valley of the lower Drina river during the second half of the 2nd century A.D. It aims to point out a connection between both procurators and Gnaeus Iulius Verus, a famous senator and general originating from the Roman colony of Aequum, in Dalmatia and one of Marcus Aurelius’ amici in the early years of the latter’s reign. The presence of the protégés of Gnaeus Iulius Verus in the richest mining region of Illyricum is indicative of two things: the emperor’s willingness to entrust these mines to the protégés of his closest associate at a time when this region was under constant threat from barbarian attacks, and also the possible intention of Gnaeus Iulius Verus to protect his own investment in mining.

  9. Deletion of Notch1 converts pro-T cells to dendritic cells and promotes thymic B cells by cell-extrinsic and cell-intrinsic mechanisms.

    Notch1 signaling is required for T cell development and has been implicated in fate decisions in the thymus. We showed that Notch1 deletion in progenitor T cells (pro-T cells) revealed their latent developmental potential toward becoming conventional and plasmacytoid dendritic cells. In addition, Notch1 deletion in pro-T cells resulted in large numbers of thymic B cells, previously explained by T-to-B cell fate conversion. Single-cell genotyping showed, however, that the majority of these thymic B cells arose from Notch1-sufficient cells by a cell-extrinsic pathway. Fate switching nevertheless exists for a subset of thymic B cells originating from Notch1-deleted pro-T cells. Chimeric mice lacking the Notch ligand delta-like 4 (Dll4) in thymus epithelium revealed an essential role for Dll4 in T cell development. Thus, Notch1-Dll4 signaling fortifies T cell commitment by suppressing non-T cell lineage potential in pro-T cells, and normal Notch1-driven T cell development repels excessive B cells in the thymus.

    Knowledge of protein function is important for biological, medical and therapeutic studies, but many proteins are still unknown in function. There is a need for more improved functional prediction methods. Our SVM-Prot web-server employed a machine learning method for predicting protein functional families from protein sequences irrespective of similarity, which complemented those similarity-based and other methods in predicting diverse classes of proteins including the distantly-related proteins and homologous proteins of different functions. Since its publication in 2003, we made major improvements to SVM-Prot with (1) expanded coverage from 54 to 192 functional families, (2) more diverse protein descriptors protein representation, (3) improved predictive performances due to the use of more enriched training datasets and more variety of protein descriptors, (4) newly integrated BLAST analysis option for assessing proteins in the SVM-Prot predicted functional families that were similar in sequence to a query protein, and (5) newly added batch submission option for supporting the classification of multiple proteins. Moreover, 2 more machine learning approaches, K nearest neighbor and probabilistic neural networks, were added for facilitating collective assessment of protein functions by multiple methods.

    T-cell lymphopenia following BM transplantation or diseases such as AIDS result in immunodeficiency. Novel approaches to ameliorate this situation are urgently required. Herein, we describe a novel stromal cell free culture system in which Lineage(-) Sca1(+)c-kit(+) BM hematopoietic progenitors very efficiently differentiate into pro-T cells. This culture system consists of plate-bound Delta-like 4 Notch ligand and the cytokines SCF and IL-7. The pro-T cells developing in these cultures express CD25, CD117, and partially CD44; express cytoplasmic CD3ε; and have their TCRβ locus partially D-J rearranged. They could be expanded for over 3 months and used to reconstitute the T-cell compartments of sublethally irradiated T-cell-deficient CD3ε(-/-) mice or lethally irradiated WT mice. Pro-T cells generated in this system could partially correct the T-cell lymphopenia of pre-Tα(-/-) mice. However, reconstituted CD3ε(-/-) mice suffered from a wasting disease that was prevented by co-injection of purified CD4(+) CD25(high) WT Treg cells. In a T-cell-sufficient or T-lymphopenic setting, the development of disease was not observed. Thus, this in vitro culture system represents a powerful tool to generate large numbers of pro-T cells for transplantation and possibly with clinical applications. © 2014 WILEY-VCH Verlag GmbH & Co.

    2004-12-01

    The Swiss-Prot protein knowledgebase provides manually annotated entries for all species, but concentrates on the annotation of entries from model organisms to ensure the presence of high quality annotation of representative members of all protein families. A specific Plant Protein Annotation Program (PPAP) was started to cope with the increasing amount of data produced by the complete sequencing of plant genomes. Its main goal is the annotation of proteins from the model plant organism Arabidopsis thaliana. In addition to bibliographic references, experimental results, computed features and sometimes even contradictory conclusions, direct links to specialized databases connect amino acid sequences with the current knowledge in plant sciences. As protein families and groups of plant-specific proteins are regularly reviewed to keep up with current scientific findings, we hope that the wealth of information of Arabidopsis origin accumulated in our knowledgebase, and the numerous software tools provided on the Expert Protein Analysis System (ExPASy) web site might help to identify and reveal the function of proteins originating from other plants. Recently, a single, centralized, authoritative resource for protein sequences and functional information, UniProt, was created by joining the information contained in Swiss-Prot, Translation of the EMBL nucleotide sequence (TrEMBL), and the Protein Information Resource-Protein Sequence Database (PIR-PSD). A rising problem is that an increasing number of nucleotide sequences are not being submitted to the public databases, and thus the proteins inferred from such sequences will have difficulties finding their way to the Swiss-Prot or TrEMBL databases.

    fomentar la realización de actividades deportivas sin o de bajo impacto. Respecto a los antiinflamatorios no esteroidales, no hay evidencia específica sobre la eficacia de estos en la literatura, pero ayudan de forma fiable a aliviar el dolor agudo asociado con la artrosis y en cierta medida con la inflamación. La suplementación con Glucosamina y Condroitín Sulfato tendría un efecto sobre la matriz extracelular y producción de ácido hialurónico, sin ser respaldado aún clínicamente en la literatura. Otra alternativa en el manejo es la infiltración con corticosteroides con un rol en tratamiento de los síntomas, pero no están exentos de riesgo. Su uso rutinario puede causar daños a los tejidos blandos alrededor de la articulación. Inyecciones de ácido hialurónico intra articulares se cree que ayudan por sus propiedades físicas y por su actividad antiinflamatoria, anabólica y efecto analgésico, con estudios que respaldan su uso. Alternativas como fisioterapia, centradas en medidas anti inflamatorias locales, fortalecimiento muscular, programas de reeducación de la marcha y ejercicios de movilización articular, modificación de calzado y uso de ortesis, pueden proporcionar alivio del dolor, mejora de la calidad de vida y posponer la cirugía en los pacientes afectados por artrosis de tobillo avanzada. Alternativas quirúrgicas no protésicas, como la artroplastia por distracción, preservar la superficie articular original y movimiento del tobillo. Los candidatos ideales son aquellos pacientes menores de 45 años que tienen artrosis postraumática moderada a severa del tobillo con una superficie articular relativamente congruente, dolor y movilidad articular bien conservada.

    Infections caused by human parasites (HPs) affect the poorest 500 million people worldwide but chemotherapy has become expensive, toxic, and/or less effective due to drug resistance. On the other hand, many 3D structures in Protein Data Bank (PDB) remain without function annotation. We need theoretical models to quickly predict biologically relevant Parasite Self Proteins (PSP), which are expressed differentially in a given parasite and are dissimilar to proteins expressed in other parasites and have a high probability to become new vaccines (unique sequence) or drug targets (unique 3D structure). We present herein a model for PSPs in eight different HPs (Ascaris, Entamoeba, Fasciola, Giardia, Leishmania, Plasmodium, Trypanosoma, and Toxoplasma) with 90% accuracy for 15 341 training and validation cases. The model combines protein residue networks, Markov Chain Models (MCM) and Artificial Neural Networks (ANN). The input parameters are the spectral moments of the Markov transition matrix for electrostatic interactions associated with the protein residue complex network calculated with the MARCH-INSIDE software. We implemented this model in a new web-server called MISS-Prot (MARCH-INSIDE Scores for Self-Proteins). MISS-Prot was programmed using PHP/HTML/Python and MARCH-INSIDE routines and is freely available at: . This server is easy to use by non-experts in Bioinformatics who can carry out automatic online upload and prediction with 3D structures deposited at PDB (mode 1). We can also study outcomes of Peptide Mass Fingerprinting (PMFs) and MS/MS for query proteins with unknown 3D structures (mode 2). We illustrated the use of MISS-Prot in experimental and/or theoretical studies of peptides from Fasciola hepatica cathepsin proteases or present on 10 Anisakis simplex allergens (Ani s 1 to Ani s 10). In doing so, we combined electrophoresis (1DE), MALDI-TOF Mass Spectroscopy, and MASCOT to seek sequences, Molecular Mechanics + Molecular Dynamics (MM/MD) to

    Previous data have shown that the 20210G>A polymorphism of the Factor II gene is related to an increased prothrombin level, which may in turn lead to a procoagulant state. The heterogeneous and multifactorial character of arterial ischemic stroke often results in contradictory reports describing the association between the 20210G>A polymorphism and arterial ischemic stroke in different populations. We performed a meta-analysis of available data addressing the relation between the FII 20210G>A polymorphism and arterial ischemic stroke, both in young adults and children. We searched PubMed using appropriate keywords. The inclusion criteria for the study were as follows: case-control study, study population consisting of children, study population consisting of young adults, arterial ischemic stroke confirmed by magnetic resonance imaging or computed tomography, and English language. The exclusion criteria included lack of genotype or allele frequencies, study design other than a case-control study, outcome definition other than arterial ischemic stroke, and previously overlapped patient groups. Finally, 30 case-control studies (14 in children and 16 in young adults) were included. Statistical analyses were conducted using R software. Heterogeneity between the studies was evaluated using the Dersimonian and Laird's Q test. In the case of significant between-studies heterogeneity, the pooled odds ratio was estimated with a random-effects model, otherwise a fixed-effects model was used. The pooled analysis showed that carriers of 20210A allele (GA+AA genotypes) of the prothrombin gene are more common in arterial ischemic stroke patients, both in children and young adults, than in control subjects (P = 0.006; odds ratio, 1.83; 95% confidence interval, 1.19 to 2.80 and P = 0.001; odds ratio, 1.69; 95% confidence interval, 1.25 to 2.28, respectively). The results of the present meta-analysis have proven that the FII 20210G>A polymorphism is associated with arterial

    The purpose of this study was to assess the typical microbiological quality of the most famous Portuguese traditional cheese, Serra da Estrela, and to assess its ripening time and geographical dependence. Ninety-six experimental cheeses manufactured from sixteen batches of milk on eight dairy farms scattered over the Appellation d' Origine Protégée (AOP) region were qualitatively and quantitatively evaluated microbiologically at various ripening times. Viable counts were performed after inoculation on appropriate selective media for aerobic mesophiles and proteolytic and lipolytic microflora, as well as lactococci, lactobacilli, species of Enterobacteriaceae, lactic streptococci, staphylococci, and yeasts. Members of the Enterobacteriaceae and lactic acid bacteria were the predominant microbial groups on all dairy farms throughout maturation; the latter are probably the microbial group responsible for most proteolytic and lipolytic breakdown in Serra da Estrela cheese. The microbial groups whose numbers were most affected by dairy-to-dairy variation were species of Enterobacteriaceae staphylococci, and enterococci, which are the most critical groups in terms of health hazards. It is therefore suggested that tighter control should be implemented at the level of choice of raw materials, in milk-handling practices, and in general throughout the manufacturing process in attempts to standardize production and consistently reduce microbiological risks (even though the distinctiveness of a few final organoleptic characteristics may somehow be reduced.

    Coagulation laboratories are faced on daily basis with requests for additional testing in already analyzed fresh plasma samples. This prompted us to examine whether plasma samples stored at room temperature (RT), and 4°C for 24 hours can be accepted for additional prothrombin time (PT), activated partial thromboplastin time (aPTT), fibrinogen (Fbg), antithrombin (AT), and D-dimer testing. We measured PT, aPTT, Fbg in 50 and AT in 30 plasma samples with normal and pathological values, within 4 hours of blood collection (baseline results) and after 24-hours storage at RT (primary tubes), and 4°C (aliquots). D-dimer stability was investigated in 20 samples stored in primary tubes at 4°C. No statistically significant difference between baseline results and results in samples stored at RT and 4°C was observed for PT (P=.938), aPTT (P=.186), Fbg (P=.962), AT (P=.713), and D-dimers (P=.169). The highest median percentage changes were found for aPTT, being more pronounced for samples stored at 4°C (13.0%) than at RT (8.7%). Plasma samples stored both at RT and 4°C for 24 hours are acceptable for additional PT, Fbg, and AT testing. Plasma samples stored 24 hours in primary tubes at 4°C are suitable for D-dimer testing. © 2017 John Wiley & Sons Ltd.

    The prothrombin time (PT) assay of factor II+VII+X activity is an important predictor of liver damage in paracetamol poisoned patients. It complicates interpretation of results that the antidote, acetylcysteine (NAC) depresses this activity. The aim was to investigate if NAC influences the accuracy of the plasma PT assay. The accuracy of Nycotest PT was studied using plasma added NAC in vitro and plasma from subjects infused with NAC. The latter results were compared with those obtained by analysis of PT by CoaguChek S. Therapeutic NAC concentrations added to plasma in vitro decreased factor II+VII+X activity at 37 degrees C in a time-dependent manner. This effect was quenched at temperatures depression of factor II+VII+X activity in plasma from subjects infused with NAC during the first 3h of infusion indicating that it contained reactive NAC. The risk that this NAC interfered with the accuracy of the PT assay was considered minimal with samples stored below 24 degrees C. This was supported by similarity of results obtained by analysis of appropriately stored plasma and simultaneously drawn blood by CoaguChek S. Residual reactive NAC does not interfere with the accuracy of the PT assay of plasma stored below 24 degrees C, but NAC-induced loss in activity at 37 degrees C may be partly recovered during subsequent storage below 24 degrees C.

Metodologia: Após exame clínico de 93 pacientes, 47 foram selecionados para exame micológico e desta amostra foram selecionados trinta pacientes: 15 com diagnóstico positivo e 15 com diagnóstico negativo de candidose foram avaliados para contagem de S. mutans, determinação de fluxo salivar e capacidade tampão. Higiene bucal e da prótese, tempo de confecção, tipo de lesão e dados salivares foram relacionados com características clínicas e laboratoriais de Candida. Resultados: As lesões frequentes foram dos tipos I (43,5% e II (53,5%. A quantidade de S. mutans foi seis vezes maior em pacientes com candidose e foi associada com baixo fluxo salivar e higiene oral deficiente. Após a terapia, a redução de S. mutans foi verificada particularmente em pacientes com fluxo salivar normal. Os valores variaram de 0,01 a 3,88 UFC/ml x 104. Conclusão: Os dados sugerem que os Streptococcus colaboram com Candida spp na etiopatogenia da estomatite protética. O uso de agentes antimicrobianos orais pode propiciar efeito benéfico para pacientes com estomatite protética submetidos à terapia antifúngica e que apresentam higiene oral deficiente e parâmetros salivares desfavoráveis

    Full Text Available Millions of life scientists across the world rely on bioinformatics data resources for their research projects. Data resources can be very expensive, especially those with a high added value as the expert-curated knowledgebases. Despite the increasing need for such highly accurate and reliable sources of scientific information, most of them do not have secured funding over the near future and often depend on short-term grants that are much shorter than their planning horizon. Additionally, they are often evaluated as research projects rather than as research infrastructure components. In this work, twelve funding models for data resources are described and applied on the case study of the Universal Protein Resource (UniProt, a key resource for protein sequences and functional information knowledge. We show that most of the models present inconsistencies with open access or equity policies, and that while some models do not allow to cover the total costs, they could potentially be used as a complementary income source. We propose the Infrastructure Model as a sustainable and equitable model for all core data resources in the life sciences. With this model, funding agencies would set aside a fixed percentage of their research grant volumes, which would subsequently be redistributed to core data resources according to well-defined selection criteria. This model, compatible with the principles of open science, is in agreement with several international initiatives such as the Human Frontiers Science Program Organisation (HFSPO and the OECD Global Science Forum (GSF project. Here, we have estimated that less than 1% of the total amount dedicated to research grants in the life sciences would be sufficient to cover the costs of the core data resources worldwide, including both knowledgebases and deposition databases.

    Introduction The aim of this study was to assess pneumatic tube system (PTS) alteration on platelet function by the light transmission aggregometry (LTA) and whole blood aggregometry (WBA) method, and on the results of platelet count, prothrombin time (PT), activated partial thromboplastin time (APTT), and fibrinogen. Materials and methods Venous blood was collected into six 4.5 mL VACUETTE® 9NC coagulation sodium citrate 3.8% tubes (Greiner Bio-One International GmbH, Kremsmünster, Austria) from 49 intensive care unit (ICU) patients on dual anti-platelet therapy and immediately hand carried to the central laboratory. Blood samples were divided into 2 Groups: Group 1 samples (N = 49) underwent PTS (4 m/s) transport from the central laboratory to the distant laboratory and back to the central laboratory, whereas Group 2 samples (N = 49) were excluded from PTS forces. In both groups, LTA and WBA stimulated with collagen, adenosine-5’-diphosphate (ADP), arachidonic acid (AA) and thrombin-receptor-activated-peptide 6 (TRAP-6) as well as platelet count, PT, APTT, and fibrinogen were performed. Results No statistically significant differences were observed between blood samples with (Group 1) and without (Group 2) PTS transport (P values from 0.064 – 0.968). The AA-induced LTA (bias: 68.57%) exceeded the bias acceptance limit of ≤ 25%. Conclusions Blood sample transportation with computer controlled PTS in our hospital had no statistically significant effects on platelet aggregation determined in patients with anti-platelet therapy. Although AA induced LTA showed a significant bias, the diagnostic accuracy was not influenced. PMID:28392742

    Full Text Available The creep behaviour of high temperature proton conducting perovskites SrCe0.9Y0.1O3-δ and Sr3Ca1.18Nb1.82O9-δ fabricated by laser fusion has been studied. Their microstructure has been studied both in the as-received and crept samples by means of Scanning Electron Microscopy (SEM and Electron BackScattering Diffraction (EBSD, to correlate plastic behaviour with the evolution of the microstructure. The materials show a cellular structure consisting of elongated grains embedded in an amorphous phase and a strong bi-axial crystallographic texture. Deformation tests at constant stress (creep tests have been performed both in Ar atmosphere and in air. Rigid grain rotation has been observed in the crept samples by EBSD. The amorphous phase flows outside the sample during creep. Plastic behaviour of these materials is independent of the environmental atmosphere and is consistent with a mechanism of viscous flow of the amorphous phase controlled by diffusion.

    2014-07-01

    Full Text Available Au cours des 30 dernières années, l’aquaculture mondiale n’a cessé de croître pour répondre à la demande croissante de poisson pour la consommation humaine qui ne peut plus être satisfaite par les seules captures de pêche. En conséquence, la demande de matières premières pour les aliments aquacoles augmente, tandis que le volume disponible de farine de poisson, ingrédient traditionnellement majoritaire dans ces aliments, reste stable. Cela a conduit à une substitution des ressources marines par des produits végétaux comme ingrédients pour les aliments pour poissons. La proportion de farine de poisson dans les aliments piscicoles a été réduite d’un tiers et est remplacée par une combinaison de sources protéiques végétales qui fournissent les acides aminés indispensables en quantité suffisante pour répondre aux besoins des poissons. Une large gamme de produits végétaux a été prospectée pour remplacer la farine de poisson. Sur la base de leur composition et de leur disponibilité sur le marché, les produits végétaux les plus utilisés en Europe sont des graines d’oléagineux (soja, colza, tournesol sous forme de tourteaux ou de concentrés protéiques, des protéagineux (lupin, féverole, pois, des céréales (maïs, blé ou des extraits de protéines obtenus à partir de céréales, comme par exemple les glutens. Néanmoins, les études ayant porté sur des taux de substitution très élevés (peu ou pas de farine de poisson ont mis en évidence des verrous physiologiques bien que les régimes contenaient tous les nutriments nécessaires : une baisse de la consommation alimentaire, de l’efficacité alimentaire et du taux de croissance des poissons, ainsi que des modifications métaboliques. Les travaux de recherche doivent être poursuivis afin d’améliorer l’efficacité nutritionnelle des produits végétaux via une réduction de leurs facteurs antinutritionnels et des toxines qu’ils contiennent

    2002-03-01

    Full Text Available Racional - A gastrectomia traz conseqüências nutricionais inevitáveis mas atenuáveis, dependendo da dietoterapia pós-operatória. Embora observada, essa desnutrição protéico-energética é pouco dimensionada, provavelmente, pela falta de consenso metodológico. Objetivo - Avaliar o grau de desnutrição protéico-energética do paciente gastrectomizado, utilizando-se de indicadores isolados ou combinados. Pacientes e Métodos - Foram estudados 71 pacientes com gastrectomia parcial (n = 53 ou total (n =18 em pós-operatório de 6 a 24 meses e 24-60 meses. Os dados dietéticos, composição corporal e bioquímicos foram analisados de acordo com o tipo de gastrectomia e tempo pós-operatório. Resultados - A cirurgia foi conseqüência de complicações de úlcera péptica (68% ou a câncer gástrico (32%. A perda de peso foi referida por 70% dos pacientes, sendo maior no grupo gastrectomia total (16 ± 5 kg do que no grupo gastrectomia parcial (10 ± 6 kg. Em geral, os pacientes apresentaram déficit antropométrico, albuminemia normal e baixa ingestão calórica, sugerindo deficiência energética crônica. A redução de hemoglobina, hematócrito e ferro ocorreu em maior intensidade e mais precocemente no grupo gastrectomia total. Assim, quando se associou hemoglobina aos indicadores albumina, linfócitos circunferência do braço e prega cutânea subescapular, a prevalência de desnutrição protéico-energética foi maior e em maior intensidade do que na ausência da hemoglobina. Conclusão - A gastrectomia resultou em desnutrição protéico-energética do tipo marasmática, acompanhada de anemia, mais intensa e precoce na gastrectomia total e gradativa na gastrectomia parcial, assemelhando-se à gastrectomia total no pós-operatório tardio.Background - Gastrectomy leads to nutritional consequences that although expected, are not usually measured due to methodological limitations. Aim - To assess the protein-energy deficiency degrees

    Directory of Open Access Journals (Sweden)

    Lourenço, Simone Vessecchi

    2007-01-01

    Full Text Available Os implantes osseointegrados e as próteses implanto-suportadas têm sido utilizados na substituição de dentes perdidos. Com a descoberta da Osseointegração o índice de sucesso em Implantodontia aumentou acarretando no desenvolvimento de vários sistemas e marcas de implantes. Entretanto, toda essa evolução na Implantodontia, não permitiu aos Cirurgiões Dentistas que eximisse o tratamento de complicações cirúrgicas e protéticas. Com o intuito de confirmar o alto número de complicações que ocorrem durante o tratamento com implantes, assim como o surgimento de constrangimentos entre profissionais e pacientes e o descuido de informar o paciente da ocorrência das complicações, foi realizado esse estudo. Os resultados informaram que 100% dos entrevistados já tiveram alguma complicação durante o tratamento e de 1810 complicações citadas pela amostra as complicações cirúrgicas que mais ocorreram foram edema e equimose (898. De acordo com o resultado somente 42% da amostra utilizavam documento escrito informando ao paciente que poderiam ocorrer complicações. Observou-se que 59 dentistas já tiveram algum constrangimento com o paciente e 13 (22,03% destes dentistas tiveram constrangimento relacionado a ocorrência das complicações cirúrgicas e protéticas. Ressalta-se a necessidade de informar aos pacientes antes da realização do tratamento da ocorrência das complicações e solucioná-las quando ocorram evitando assim as lides judiciais

    Full Text Available Os fatores de coagulação são parte integrante da hemostasia normal, e tanto as coagulopatias hereditárias como adquiridas que envolvem este sistema são de grande importância veterinária, geralmente evidenciadas por manifestações clínicas, tais como, petéquias, equimoses, hematomas e sangramentos tardios. O presente trabalho teve por objetivo a determinação dos valores de referência do tempo de protrombina (TP e tempo de tromboplastina parcial ativada (TTPa, por métodos manuais. Para tanto, utilizou-se "kits" para dosagens humanas, devido à inexistência de produtos similares de uso específico veterinário. Foram utilizados 40 cães clinicamente sadios, sem raça definida, machos ou fêmeas, de diferentes idades. As amostras sanguíneas foram de 2,5ml cada, colhidas por venopunção cefálica e acondicionadas em tubos de centrífuga contendo 0,25ml de citrato de sódio a 3,8%. O plasma foi imediatamente separado por centrifugação e as determinações de TP e TTPa foram realizadas utilizando-se "kits" comerciais "HemoStat Thromboplastin-SIª" e "HemoStat aPTT-El b", respectivamente. Os resultados obtidos foram de 6,87 ± 1,4 segundos para o TP com valores mínimo e máximo de 4,07 e 9,67, respectivamente, e de 15,10 ± 1,6 segundos para TTPa com valores mínimo e máximo de 11,9 e 18,3, respectivamente. Conclui-se, que os valores obtidos neste trabalho podem ser utilizados como referência. Os reagentes utilizados para plasma humano podem ser empregados para o plasma de cães.The coagulation factors are part of normal hemostasis, and both hereditary and acquired coagulopathies that involve this system have an important role in veterinary medicine, generally evidenced by clinical signs such as: petechias, ecchymosis, hematomas and late hemorrhagies.

    Full Text Available Foi proposto recentemente que a solubilidade protéica in vitro com pepsina na concentração de 0,0002% é melhor que em concentrações maiores, para melhor classificar a qualidade protéica de farinhas de origem animal (FOA. Entretanto, nessa concentração, desconhece-se qual é o intervalo que melhor exprime a qualidade por meio da solubilidade protéica das FOA. Este trabalho foi conduzido com o objetivo de identificar os valores da solubilidade protéica de farinhas de subprodutos do abate de aves (FSA, utilizadas como modelo experimental. As fontes protéicas foram duas FSA e caseína (considerada padrão com 100% de solubilidade protéica. Todas as farinhas foram autoclavadas a 120ºC, durante 0, 10, 20, 40 e 80 minutos. As concentrações utilizadas da pepsina em solução de HCl 0,0744N foram de 0,0002 e 0,02%. O delineamento experimental foi o de blocos casualizados em esquema fatorial 3 (fontes x 5 (temperaturas x 2 (concentrações, com quatro repetições para a enzima na concentração de 0,0002% e duas repetições para a concentração de 0,02%. Foram determinados os valores de solubilidade protéica in vitro em solução ácido/pepsina e energia metabolizável in vivo das FSA. Os resultados indicaram que, na concentração de pepsina de 0,0002%, os valores de boa qualidade das FSA estão acima de 55%. Da mesma forma, solubilidades próximas a 84% podem ser consideradas boas, mas decaem em solubilidade e são consideradas ruins se tiverem em torno de 67% de solubilidade protéica em pepsina a 0,02%.It was recently proposed that the in vitro protein solubility is better to classify animal by-product meals (ABP using pepsin concentration of .0002% than with higher concentrations. However on this concentration no reference value exists to express ABP quality based on protein solubility. The objective of this study was to obtain protein solubility values for poultry by-product meals (PBP, as model to ABP. Two PBP and casein

    Full Text Available O feijão é cultivado e consumido mundialmente e é a leguminosa mais consumida na América Latina. O baixo valor biológico das proteínas do feijão pode ser resultante, dentre outros, da presença de fatores antinutricionais presentes no tegumento do grão. Este trabalho visou avaliar, através de ensaios biológicos, o efeito da retirada do tegumento e das antocianinas e outros polifenóis do feijão-preto, na qualidade de suas proteínas. Foram analisados o quociente de eficiência protéica, o quociente de eficiência líquida protéica e a utilização líquida da proteína, e digestibilidade. Os resultados obtidos mostraram que a eliminação parcial do tegumento dos grãos cozidos e secagem em estufa diminuíram significativamente o valor do quociente de eficiência protéica comparativamente ao do grão integral cozido e secado nas mesmas condições. A extração, com etanol acidificado, de 27,5% dos polifenóis não influiu significativamente no valor protéico do feijão-preto. Concluiu-se que a retirada do tegumento e a extração parcial de polifenóis do feijão não elevaram a sua qualidade protéica.Bean seeds (Phaseolus vulgaris, L. are cultivated and consumed all over the world and are a staple food in most countries of South America. The low biological value of bean proteins may be due to, among others, the effect of antinutritional factors on the tegument. The objective of this work was to evaluate, through biological assays, the effect of removal of black bean tegument, anthocyanins and other polyphenols on protein quality. The protein efficiency ratio, the protein liquid efficiency ratio, the protein liquid utilization and the digestibility were analyzed. The results indicated that removal of the tegument of cooked beans reduced their protein value (PER when compared to whole cooked beans. The ethanolic extraction of 27.5% of polyphenols did not increase the protein quality of beans. It was concluded that removal of the

    Full Text Available Protein-calorie malnutrition (PCM is usually found in children, the elderly, patients suffering from neoplasia or chronic disease, patients undergoing chemotherapy, or even patients under parenteral nutrition. PCM presents a wide spectrum of signs and symptoms that are a result of not only the cause(s that led to malnutrition, but also of the different degrees of protein or carbohydrate deficiency. Here we present data obtained from observational and experimental epidemiological studies that suggest that malnourished individuals frequently present a greater susceptibility to infection with high morbidity and mortality indices. Data both found in literature and obtained by our group evidence that malnutrition modifies the organism's defence processes, impairing lympho-haematopoietic organs and modifying immune response. The haematological alterations in malnutrition, such as leucopoenia and hypoplasia, are described, with an emphasis on the results in experimental protein malnutrition obtained by our group. In particular, the structural and ultra-structural alterations of bone marrow, spleen and thymus; functional alterations such as the reduction of cell migration and spreading, phagocytosis, bactericidal and fungicidal activity as well as alterations in the production of reactive oxygen species are discussed. The implications of modifications of the haemopoietic environment in malnutrition states are still obscure, however, they seem to be responsible for inefficient haemopoiesis, especially inefficient myelopoiesis, and they seem to be irreversible over the short-term.Desnutrição protéico-calórica (DPC é geralmente encontrada em crianças, idosos, pacientes com neoplasias ou doenças crônicas, pacientes submetidos à quimioterapia ou à nutrição parenteral.

    Full Text Available During pathogenic infection, hundreds of proteins that play vital roles in the Verticillium dahliae-host interaction are secreted. In this study, an integrated proteomic analysis of secreted V. dahliae proteins was performed, and a conserved secretory protein, designated VdCP1, was identified as a member of the SnodProt1 phytotoxin family. An expression analysis of the vdcp1 gene revealed that the transcript is present in every condition studied and displays elevated expression throughout the infection process. To investigate the natural role of VdCP1 in V. dahliae, two vdcp1 knockout mutants and their complementation strains were generated. Bioassays of these mutants revealed no obvious phenotypic differences from the wild-type (WT in terms of mycelial growth, conidial production or mycelial/spore morphology. However, compared with the WT, the vdcp1 knockout mutants displayed attenuated pathogenicity in cotton plants. Furthermore, treating plants with purified recombinant VdCP1 protein expressed in Pichia pastoris induced the accumulation of reactive oxygen species (ROS, expression of several defense-related genes, leakage of ion electrolytes, enhancement of defense-related enzyme activity and production of salicylic acid. Moreover, VdCP1 conferred resistance to Botrytis cinerea and Pseudomonas syringae pv. tabaci in tobacco and to V. dahliae in cotton. Further research revealed that VdCP1 possesses chitin-binding properties and that the growth of vdcp1 knockout mutants was more affected by treatments with chitinase, indicating that VdCP1 could protect V. dahliae cell wall from enzymatic degradation, which suggests an effector role of VdCP1 in infecting hosts.

    Full Text Available O sistema de condicionamento de ar adsortivo evaporativo funciona com a desumidificação do ar externo, forçando-o a passar através de um adsorvente, onde parte do vapor de água é retido e o ar quase seco é umidificado através de resfriadores evaporativos para redução de sua temperatura. O desumidificador adsortivo utilizou cerca de 4,4 kg de sílica-gel com diâmetro de 2 a 5 mm sobre telas metálicas garantindo maior rigidez à estrutura, melhor distribuição da sílica e circulação do ar. A sílica-gel foi regenerada através de aquecedor elétrico com fluxo de ar forçado por um período de 4 horas. O climatizador comercial tipo resfriador evaporativo foi testado com fibras evaporativas sintéticas e naturais. Os resultados mostraram que dependendo do painel evaporativo ocorre uma maior perda de carga no escoamento, provocando a diminuição da velocidade e comprometendo o rendimento do equipamento. O sistema completo foi testado, verificandose que o desumidificador reduziu a razão de umidade do fluxo de ar, mas o aumento da temperatura do ar associado ao calor de adsorção comprometeu o rendimento do protótipo. Portanto, para obter conforto térmico com o condicionador adsortivo evaporativo será necessário resfriar o ar após o desumidificador com a circulação da água do climatizador.

    Full Text Available Sendo a cibercultura a cultura dominante da nossa sociedade pós-massiva, é razoável supor que seus elementos influenciem os produtos desta cultura, mesmo os não-massivos, como a publicidade de moda veiculada em revistas. Partindo desta premissa, este trabalho busca verificar a presença de aspectos da cibercultura em anúncios de marcas de vestuário feminino veiculados na revista Elle, especialmente as concepções de corpo protético e remodelado. A análise revela a presença destas concepções nos anúncios, ainda que algumas sejam mais sutis, devido à necessidade de aceitação dos anúncios e dos produtos pelas consumidoras. Considering cyberculture as dominant in our post-massive society, it is reasonable to assume that its elements influence the products of this culture, even the non-massive ones, like fashion ads in women's magazines. Starting from this premise, this paper seeks to verify the presence of aspects of cyberculture in women's clothing branding ads in Elle magazine, especially the concepts of prosthetic and remolded bodies. The analysis reveals the presence of these conceptions in ads, although some of them are more subtle, due to the need for acceptance of ads and products by consumers. The work is especially based on the cyberculture concepts of André Lemos (2008 and aspects of the post-human body of Lucia Santaella (2003 and Cristiane Mesquita (2004.

    Full Text Available The aerial parts of cassava, constituted by leaves, stalk sand stems, are considered as agro-industrial waste, so, they are thrown away during roots crop. This material has content of protein, vitamin and mineral; therefore, it can be used as a dietary supplement for food industries. Thus, alternatives have come to extract protein from leaves and remove toxic agent sand anti-nutrients that make part of their composition. In this context, this study aimed at evaluating yield, mineral composition and functional properties of protein concentrates from leaves and aerial part of cassava. During the extraction of proteins, the following tested methods were:(1 isoelectric precipitation; (2 natural fermentation for five days; (3 fermentation for 48 hours and (4 fermentation for 48 hours, followed by pH adjustment. A 2 x 4 factorial design was used, the studied factors were the products (leaves and shoots and the method of protein extraction (four methods, with three replications. From the results, it was observed that Method1 provided the highest yields of protein concentrate and protein extraction for cassava leaves, however, there was no significant difference among the extraction methods for the aerial part of cassava. The values of Fe, Mn and Zn increased in protein concentrates obtained both in leaves and the aerial part of cassava, especially for Method 3. The capacities of absorbing water and oil from protein concentrates were considered high for the four studied methods, thus, indicating a good application in food products.As partes aéreas da mandioca, representadas pelas folhas, hastes e caules, constituem-se como resíduos agroindustriais por serem desperdiçadas na colheita das raízes.

    In a population-based case-control study (PROtEuS), we examined the association between prostate cancer (PCa) and (1) benign prostatic hypertrophy (BPH) history at any time prior to PCa diagnosis, (2) BPH-history reported at least 1 year prior to interview/diagnosis (index date) and (3) exposure to BPH-medications. Cases were 1933 men with incident prostate cancer diagnosed across Montreal French hospitals between 2005 and 2009. Population controls were 1994 men from the same age distribution and residential area. In-person interviews collected socio-demographic characteristics and medical history, e.g., BPH diagnosis, duration and treatment, as well as on PCa screening. Logistic regression analyses tested overall and grade-specific associations, including subgroup analyses with frequent PSA testing. A BPH-history was associated with an increased risk of PCa (OR 1.37 [95 % CI 1.16-2.61]), more pronounced for low-grade PCa (Gleason ≤6: OR 1.54 [1.26-1.87]; Gleason ≥7: OR 1.05 [0.86-1.27]). The association was not significant when BPH-history diagnosis was more than 1 year prior to index date, except for low-grade PCa (OR 1.29 [1.05-1.60]). Exposure to 5α reductase inhibitors (5α-RI) resulted in a decreased risk of overall PCa (OR 0.62 [0.42-0.92]), particularly for intermediate- to high-grade PCa (Gleason ≤6: OR 0.70 [0.43-1.14]; Gleason ≥7: OR 0.43 [0.26-0.72]). Adjusting for PSA testing frequency or restricting analyses to frequently screened subjects did not affect these results. BPH-history was associated with an increased PCa risk, which disappeared, when BPH-history did not include BPH diagnosis within the previous year. Our results also suggest that 5α-RI exposure exerts a protective effect on intermediate and high-grade PCa.

    Full Text Available High temperature protonic conductors (HTPC were successfully fabricated by melt growth using the laser heated floating zone method (SrCe0.9Y0.1O3-δ, SrCe0.8Y0.2O3-δ, SrZr0.9Y0.1O3-δ, SrZr0.8Y0.2O3-δ, Sr3(Ca1.18Nb1.82O9-δ and SrTi0.95Sc0.05O3-δ. Microstructural characterization was performed by scanning and transmission electron microscopy (SEM, TEM. The materials have a cellular microstructure, with cell width ranging between 10-50 μm and intercellular regions up to 1 μm thick. The diffraction analysis indicates that the cells are crystalline, and the intercellular regions are amorphous. TEM reveals that the cells present multiple planar defects, separating rotated regions with of same crystallographic structure. The high temperature mechanical properties were studied by compression tests performed under constant strain rate and constant load. Remarkable high temperature strengths of 500 MPa at 700 oC, 400 MPa at 1100 oC and 370 MPa at 1300 oC were measured, being the plastic deformation evident at 1100 ºC and 1300 ºC. The best mechanical behavior was obtained for the systems Sr3(Ca1.18Nb1.82O9-δ and SrZr0.9Y0.1O3-δ. The strengths and creep resistance of these systems are better than the ones of polycrystalline HTPC ceramics of similar structure and composition.

Forty extracted premolars (80 root canals of dogs were used. The root canals were cleaned, shaped and filled by the lateral condensation technique using Sealer 26TM. The post space was created removing two thirds of the filling material within the root canal. The canals were randomly divided in three groups, which were treated as follows: Group A received the ScotchbondTM Multi-Purpose adhesive system; for Group B the cyanoacrylate adhesive, Super BonderTM, was employed; and no adhesive was applied into the post space for Group C (control group. A glass ionomer provisional restoration was placed allowing the sealer to set for 72 hours. Then the restoration was removed and the root canal was exposed to the oral environment for 45 days. The dogs were then killed and their jaws were removed. The post spaces were filled with India ink and the teeth were restored for 96 hours. Afterwards, the teeth were extracted and the roots were sectioned at the furcation for allocation to their specific groups. The teeth were turned transparent and the quantitative analysis of leakage was performed using light microscopy. The results showed no significant differences between groups, rejecting the initial hypothesis. Leakage occurred in a great extent in all specimens. Therefore, sealing post spaces with the adhesives used in this study was not an effective method to prevent microleakage.Esse estudo in vivo analisou a capacidade de selamento do canal protético com dois adesivos, o Super Bonder® (Henkel Loctite Adesivos Ltda., Itapevi, SP e o Scotchbond® Multi-Purpose (3M Dental Products, St. Paul, MN, EUA, testando a

Tetraethylorthosilicate (TEOS, methyl triethoxysilane (MTES, titanium tetrachloride (TiCl4 and phosphorus trichloride (PCl3 have used as precursors and cetyl trimethylammonium bromide (CTAB as porous generator agent. Films were deposited by immersion technique controlling the relative humidity at 40 and 20-70% and treated at 400 to 500° C for 15, 30, 45 and 60 min. The variation of the refractive index and thickness have studied as a function of temperature and sintering time as well as the pore volume and density of the coatings by spectroscopic ellipsometry. Moreover, the hydrophobic/hydrophilic character of the coatings has been studied by Transform Infrared Spectroscopy (FTIR and by contact angle measurements, following the loss of methyl groups with the temperature and sintering time. The results show that these parameters are crucial to obtain coatings with high porosity and low contact angle, important to obtain high proton conductivity conditions. The sintering conditions were fixed to 400°C / 60 min. Conductivity measurements at four points show high proton conductivity, 0,16 and 0,85 S/cm, up and down ramp, respectively, at 80°C and 80 % of humidity. These coatings are good candidates for PEMFC membranes, if they are deposited onto electrodes.El artículo describe la preparación de recubrimientos mesoporosos de SiO2-TiO2-P2O5 por el método sol-gel combinado con el método EISA para su aplicación como membranas en pilas de intercambio protónico.

    Full Text Available Este estudo tem por objetivo investigar a relação existente entre a desnutrição energético-protéica e a cárie dentária precoce na primeira infância. Trata-se de uma comunicação, para a qual foi realizada uma revisão da literatura, a partir de análise documental de produção bibliográfica, baseada em levantamentos de periódicos e consultas a livros. Verificou-se que a cárie precoce na infância é altamente prevalente nas comunidades de baixa renda, nas quais a desnutrição é um fator comum e de grande relevância. Estudos mostram que crianças desnutridas tendem a apresentar defeitos estruturais no esmalte do dente, como também estão predispostas a um maior risco à cárie dentária. Portanto, uma deficiência energético-protéica durante a fase de desenvolvimento dentário (odontogênese tem demonstrado uma maior suscetibilidade à cárie dentária, atraso na cronologia de erupção e defeitos estruturais do esmalte (hipoplasia de esmalte, hipofunção das glândulas salivares e mudança na composição da saliva. Estes fatores podem ser os mecanismos pelos quais a desnutrição associa-se à cárie. Em conclusão, os estudos sugerem que a deficiência energético-protéica durante a odontogênese gera atraso na cronologia de erupção e defeitos estruturais no esmalte (hipoplasia, além de poder afetar as glândulas salivares, aumentando o risco de ocorrência da doença cárie.

    Full Text Available A desnutrição protéico-energética constitui problema comum aos pacientes com insuficiência renal crônica, influenciando diretamente na sua morbi-mortalidade. A acidose metabólica tem papel no catabolismo protéico, ativando a via proteolítica proteasoma-ubiquitina, dependente de adenosina trifosfato, e conjuntamente com glicocorticóides induz uma maior atividade na desidrogenase que degrada os aminoácidos de cadeia ramificada. Esta revisão teve como objetivo descrever o mecanismo pelo qual a acidose metabólica nos pacientes com insuficiência renal crônica promove o catabolismo protéico, favorecendo assim a desnutrição, bem como avaliar os efeitos do uso de bicarbonato de sódio na correção da acidose e conseqüentemente redução do catabolismo protéico. Pesquisas mostram melhora da acidose pelo uso de bicarbonato de sódio e conseqüente redução do catabolismo protéico na insuficiência renal crônica, podendo ser esta uma conduta promissora na atenuação da desnutrição nestes pacientes.Protein-Energy Malnutrition is common among patients with chronic kidney failure, thus increasing morbidity and mortality. Several studies have shown that metabolic acidosis is a major cause of muscle protein breakdown, and recently it was attributed to ATP-dependent ubiquitin-proteasome proteolytic pathway. Acidosis, plus glucocorticoids, also respond to increasing branched-chain amino acids oxidation. In this review, the impact of metabolic acidosis on protein and amino acid metabolism is examined in order to understand its effect on lean body mass and the nutritional status of patients with chronic kidney failure. The study also observes whether or not sodium bicarbonate supplementation is beneficial to chronic kidney failure patients. In summary, there is a preliminary evidence suggesting that the correction of acidosis using sodium bicarbonate reduces protein degradation in chronic kidney failure patients, thus emerging as a

    Full Text Available Cachaça is the denomination of a typical and exclusive Brazilian spirit produced from the distillation of fermented sugarcane juice must. The objective of this study was to evaluate the effect of adding yeast extract to the sugarcane juice used for sugarcane liquor production, because for the artisanal process no studies are available on nitrogen addition nor beverage quality, involving nitrogen complementation. Results of previous studies in the laboratory scale showed that sugarcane juice complementation with proteic nitrogen can be a beneficial practice for yeast multiplication and cellular growth, and also for the improvement of fermentation yield and liquor productivity. In this pilot scale study, using recycled yeast, the addition of proteic nitrogen influenced positively the cell viability, confirmed the yeast recycling operation, and also reduced the fermentation time. The proteic nitrogen addition did not affect the sensory acceptance of the distillate, and did not change the contents of volatile compounds, indicating that assimilable forms of proteic nitrogen can be helpfull to improve the alcoholic fermentation for cachaça production.Cachaça é a denominação de uma típica e exclusiva bebida destilada brasileira produzida a partir da destilação do caldo fermentado da cana-de-açúcar. O objetivo deste estudo foi avaliar a adição de extrato de levedura no mosto de caldo de cana para a produção de cachaça, pois em processo artesanal não há estudos específicos sobre as características fermentativas da levedura assim como sobre a qualidade da bebida, envolvendo a complementação nitrogenada e em específico a aplicação de nitrogênio protéico. Os resultados obtidos em trabalhos anteriores, conduzidos em laboratório, indicaram que nas destilarias artesanais de aguardente a complementação protéica do mosto pode constituir uma prática benéfica para a multiplicação e crescimento celular do fermento e conseq

    As proteínas são moléculas essenciais aos organismos animais, devendo, portanto, estar presentes na alimentação em quantidades adequadas. Além do aspecto quantitativo deve-se considerar o aspecto qualitativo, isto é, seu valor nutricional, que dependerá da composição, digestibilidade, biodisponibilidade de aminoácidos essenciais, ausência de toxicidade e de fatores antinutricionais. O objetivo do presente estudo foi determinar a digestibilidade in vivo e a qualidade nutricional de proteínas de pães de sal obtidos com farinhas mistas de trigo e linhaça integral nas proporções de 90:10 e 85:15. Os melhores resultados para ganho de peso, coefi ciente de efi cácia alimentar, coefi ciente de efi cácia protéica e razão protéica líquida foram obtidos quando maior teor de farinha de trigo foi substituído pela farinha integral de linhaça na formulação dos pães. A lisina foi o primeiro aminoácido limitante em todos os produtos elaborados. A substituição parcial da farinha de trigo pela farinha de linhaça não melhorou a qualidade protéica dos pães estudados.

    Full Text Available Contrary to internal combustion engines, proton-exchange membrane fuel cells (PEMFC used in transportation operate with zero emissions of environmental pollutants. The increase of the operation temperature in PEMFC above 100°C is a great concern for the application of this type of cells in electric vehicles. Hybrid organic-inorganic membranes with nanosized interfaces can combine the main properties of their components to meet this objective. Styrene-methacrylate-silica membranes doped with phosphotungstic acid (PWA were prepared through acid catalyzed sol-gel process and free-radical copolymerization. Additionally, sulfonation processes of aromatic rings to produce attached SO3H groups were applied to increase the proton conductivity. The effect of sulfonation degree and PWA doping on the membrane properties such as chemical and thermal stability, water uptake, ion exchange capacity, and proton conductivity were investigated. The measurement of conductivity shows a general increase with rising temperatures and with the increasing of SO3H groups density, reaching a maximum value of 3.2 10-3 S/cm at 130ºC and 100%HR.

    Comparadas con los motores de combustión interna, las pilas de combustible de intercambio de protones (PEMFC son capaces de operar sin emisiones de agentes contaminantes. El aumento de la temperatura de operación de la pila de combustible por encima de 100ºC es uno de los grandes objetivos en este campo ya que facilitaría el desarrollo comercial de los vehículos eléctricos impulsados por pilas de combustible. Las membranas híbridas orgánico-inorgánicas nanoestructuradas combinan las propiedades necesarias para este tipo de aplicación. Se obtuvieron membranas híbridas dopadas con ácido fosfowolfrámico (PWA por copolimerización radicálica a partir de alquilalcóxidos y monómeros de estireno y metacrilato, y por reacción sol-gel vía catálisis ácida.

    Full Text Available PURPOSE: To investigate the facial symmetry of rats submitted to experimental mandibular condyle fracture and with protein undernutrition (8% of protein by means of cephalometric measurements. METHODS: Forty-five adult Wistar rats were distributed in three groups: fracture group, submitted to condylar fracture with no changes in diet; undernourished fracture group, submitted to hypoproteic diet and condylar fracture; undernourished group, kept until the end of experiment, without condylar fracture. Displaced fractures of the right condyle were induced under general anesthesia. The specimens were submitted to axial radiographic incidence, and cephalometric mensurations were made using a computer system. The values obtained were subjected to statistical analyses among the groups and between the sides in each group. RESULTS: There was significative decrease of the values of serum proteins and albumin in the undernourished fracture group. There was deviation of the median line of the mandible relative to the median line of the maxilla, significative to undernutrition fracture group, as well as asymmetry of the maxilla and mandible, in special in the final period of experiment. CONCLUSION: The mandibular condyle fracture in rats with proteic undernutrition induced an asymmetry of the mandible, also leading to consequences in the maxilla.OBJETIVO: Investigar a simetria facial de ratos submetidos à fratura experimental de côndilo mandibular e com desnutrição protéica (8% de proteína por meio de mensurações cefalométricas.

    Full Text Available A perfilometria é uma técnica amplamente utilizada na construção de mapas e gráficos de relevos aplicados a uma vasta área do conhecimento. Frente às necessidades de suprir a demanda da indústria e da área de desenvolvimento de protótipos quanto a técnicas não invasivas na investigação da superfície de materiais em geral, o presente trabalho buscou propor uma metodologia de calibração aplicada à técnica de moiré para investigações perfilométricas em protótipos mecânicos buscando baixos custos e flexibilidade. A técnica de moiré consiste na comparação de dois retículos periódicos, onde um segue o comportamento da superfície do objeto (retículo modelo - Rm e outro não está deformado, seguindo o comportamento de um plano de referência, (retículo de referência - Rr. A luz que passa entre os retículos se sobrepõe formando padrões de moiré ou franjas de moiré que se comportam como ondas senoidais. Nos ensaios de calibração, usou-se um cone de relevo conhecido para a determinação de uma constante de correção de mapas gerados digitalmente. Os ensaios realizados aplicaram a metodologia para a determinação do perfil de um mouse de computador e para a determinação da deformação de uma chapa metálica. A metodologia proposta para a calibração da técnica de moiré mostrouse capaz de realizar os mapeamentos, com resolução máxima na ordem de centésimos de milímetros, podendo então ser usada em aplicações com níveis de precisão inferiores a essa ordem.Profilometry is a measurement technique widely used in map and relief graphic construction, being applied to vast areas of knowledge.

    Full Text Available Au cours des trente dernières années, les différentes expérimentations menées en matière de protection de la faune sauvage au Brésil ont conduit à l’élaboration d’aires protégées habitées, jugées plus acceptables et justes sur le plan social. Or, depuis la création de ces espaces, de nombreuses voix ont remis en cause le bien-fondé de ce genre de réserve, considérant que la cohabitation avec la faune sauvage pouvait potentiellement avoir des effets négatifs dans les domaines environnementaux et sociaux. Cet article s’intéresse à l’état des conflits entre humains et faune sauvage dans une communauté appartenant à la réserve de développement durable de Tupé, à la périphérie de Manaus. Il observe notamment la façon dont les conflits sont perçus et résolus afin de montrer la diversité des représentations quant aux espèces problématiques ainsi que les enjeux sociaux et environnementaux qui reposent sur leur protection.  During the last thirty years, few different experiments on protection of wild fauna in Brazil have led to the development of inhabited protected areas, seen as socially more acceptable and fairer. However, since their creation, the validity of this kind of protected areas has been questioned, considering that the coexistence between men and wild fauna may have negative effects for environment as well as local communities. This paper focuses on human/wildlife conflicts in a rural community in the sustainable development reserve of Tupé, located in the periphery of Manaus city. It mainly observes how conflicts are perceived and resolved and it shows how diverse are the representations regarding problematic species, as well as environmental and social issues related to their protection.

    Full Text Available Le tourisme est souvent présenté comme l’un des instruments d’un développement durable, même s’il connaît une expansion difficilement maîtrisable, au détriment du patrimoine environnemental, insulaire et littoral en particulier, comme dans les DOM-TOM.Le tourisme a des impacts, culturels et sociaux notamment, sur l’environnement. Les ressources du patrimoine alimentent de leur côté la demande et l’offre touristiques. Un tourisme assis sur une gestion ad hoc des ressources du patrimoine constitue un facteur puissant de durabilité du développement local. La soumission de l’activité touristique aux exigences de protection, de conservation et de gestion reproductible de la biodiversité et du patrimoine naturel, dans les aires protégées de la Caraïbe française en particulier, génère des approches, des stratégies et des comportements nouveaux. La démarche écotouristique appelle une gestion participative et intégrée des ressources et des espaces, et constitue un défi pour les opérateurs du tourisme comme pour les acteurs de l’environnement, et une opportunité de "réappropriation" de leur milieu de vie par les populations locales. Il faut alors en clarifier le concept et les implications ; puis en analyser les objectifs et les enjeux dans une perspective de développement durable.Tourism often appears as one a tool for a sustainable development, even if it is not easy to control, in the détriment of island and costal environment heritage, as in French overseas regions.

If based on an appropriate management of those resources, it may be a strong incentive for local sustainable development.

A fim de confirmar ou não, a possível ação fungicida destas proteínas a partir de extratos de sementes de leguminosas arbóreas, o objetivo deste estudo foi detectar inibidores de tripsina em sementes de Caesalpinia ferrea (CfTI e Swartzia polyphylla (SpTI e testar os extratos contra os fungos fitopatogênicos Colletotrichum guaranicola, Corynespora cassiicola, Fusarium oxysporum e Sclerotium rolfsii, avaliando o crescimento micelial e a esporulação. Para tanto, amostras do material biológico vegetal, sementes finamente pulverizadas, foram submetidas à extração em NaCl 150 mM. Os extratos protéicos foram parcialmente purificados em coluna Sephadex G-100, submetidos à detecção dos inibidores e SDS-PAGE (12,5% e, utilizados nos bioensaios contra os fungos. O perfil eletroforético revelou uma única banda em CfTI e oito bandas em SpTI. Os extratos de C. ferrea e S. polyphylla exibiram efeito na diminuição da esporulação dos fungos testados, mas S. rolfsii foi inibido apenas por C. ferrea. Quanto ao crescimento micelial, os dois extratos tiveram efeito sobre F. oxysporum e S. rolfsii, ao passo que C. guaranicola foi inibido apenas por S. polyphylla, e C. cassiicola por C. ferrea. Concluiu-se que sementes de C. ferrea e S. polyphylla apresentam inibidores de tripsina. Além disso, os resultados sugerem que estas espécies de leguminosas arbóreas são promissoras no que concerne à prospecção de fungicidas naturais, uma vez que os extratos diminuíram o crescimento micelial e a esporulação de C. guaranicola, C. cassiicola, F. oxysporum e S. rolfsii.

    Full Text Available Introducción Conjuntamente al aumento de los reemplazos totales de rodilla (RTR realizados anualmente se ha incrementado el número de infecciones posteriores a esta  cirugía. Está demostrado en la bibliografía mundial que las revisiones en dos tiempos logran mayores porcentajes de curación que las efectuadas en un solo tiempo. El objetivo del presente trabajo es mostrar nuestros resultados en revisiones de RTR infectadas, tratadas en 2 tiempos, con la utilización de espaciadores estáticos. Material y Método Entre 1997 y 2010 se efectuaron en nuestro centro 153 revisiones de RTR de los cuales 33 (21% fueron a causa de una infección peri protésica crónica, tratada en 2 tiempos con el uso de un espaciador estático de cemento con ATB. La serie se conformó de 33 rodillas en 32 pacientes, con un promedio de edad de 69 años y un seguimiento de 3,5 años. Resultados De las 33 rodillas se obtuvo la curación en 30 (91%. Veintiocho rodillas fueron reimplantadas exitosamente,  2 rodillas con curación de la infección no fueron reimplantadas por distintos motivos y permanecieron con el espaciador en forma definitiva y en 3 hubo persistencia de la infección. De las 28 reimplantadas todas evolucionaron favorablemente, logrando una movilidad de 90° a los 3,15 meses POP en promedio. Conclusión Con la utilización de espaciadores estáticos de rodilla obtuvimos un porcentaje de curación similar a los publicados con el uso de espaciadores articulados. La ventaja de los primeros es su fácil fabricación y colocación, otorgándole a la articulación una adecuada estabilidad con un bajo costo económico.

    Full Text Available Os autores estudaram a influência da nutrição protéica na consolidação de fraturas em 40 ratos Lewis divididos em 4 grupos de 10. Durante 6 semanas os grupos 1, 2 e 3 receberam respectivamente dietas com 0, 19% e 36% de proteínas. O grupo 4 recebeu dieta sem proteínas durante as 2 primeiras semanas e com 36% de proteínas nas 4 semanas seguintes. Foram realizadas fraturas nas tíbias esquerdas ao final de 2 semanas e após 4 semanas das fraturas os animais foram sacrificados para estudo dos calos ósseos. Para a avaliação dos resultados foram utilizadas medidas clínicas, bioquímicas, radiográficas, densitométricas, e histomorfométricas. Concluiu-se que a dieta hiperprotéica alterou a consolidação óssea produzindo um calo maior e mais resistente, mas não alterou a qualidade em concentração de cálcio e em porcentagem a quantidade de tecido ósseo.The authors investigated the influence of a protein diet on fracture healing in 40 Lewis rats divided into four groups of ten. During 6 weeks, Groups 1, 2 and 3 were fed diets containing, respectively, 0.19% and 36% protein. Group 4 was fed a proteinless diet during the first two weeks and a 36%-protein diet during the next 4 weeks. At two weeks, fractures were performed in the left tibias; all animals were killed 4 weeks later so that the bone calluses could be investigated. Clinical, biochemical, radiographic, densitometry and histomorphometry measurements were performed to evaluate the findings. The conclusion was that the hyperprotein diet altered bone healing by producing a larger, more resistant callus, although it did not change quality as regards calcium levels and the percentage amount of bone tissue.

    Full Text Available It is still controversial whether intestinal parasitic infections can influence the nutritional status of children. The relationship between protein-energy malnutrition, vitamin A and parasitic infections was evaluated in 124 children. The food intake estimated by recall method was generally low and poor. Seventy five percent of the children were infected with intestinal parasites. The mean±SD weight-for-age and height-for-age Z-score were skewed one standard deviation to the left, when compared to normal standards. An association was found between protein-energy malnutrition and Giardia lamblia, but not with Ascaris lumbricoides or Hymenolepis nana infection. Only Giardia-infected children had a decreased weight-for-age and weight-for-height Z-score. Hypovitaminosis A was a major nutritional problem, but no relationship between this deficiency and parasitic infection was found. Our data indicate that low and poor food intake were the major cause of protein-energy malnutrition among the children, and except for Giardia, this was not influenced by parasitic infections.É controverso se parasitismo intestinal interfere no estado nutricional. A relação entre desnutrição energético-protéica, vitamina A e parasitoses intestinais foi avaliada em 124 crianças.

    Full Text Available The objective of this work was to investigate heterosis and its components in 16 white grain maize populations presenting high quality protein. These populations were divided according to grain type in order to establish different heterosis groups. The crosses were carried out according to a partial diallel cross design among flint and dent populations. Seven agronomic traits were evaluated in three environments while four leaf diseases and incidence of corn stunt were evaluated in one. Least square procedure was applied to the normal equation X'Xbeta = X'Y, to estimate the model effects and their respective sum of squares. Among the heterosis components, in diallel analysis, significance for average heterosis in grain yield, number of days to female flowering and to all evaluated diseases was detected. Specific heterosis was significant for days to female flowering and resistance to Puccinia polysora. Results concerned to grain yield trait indicate that populations with superior performance in dent group, no matter what flint population group is used in crosses, tend to generate superior intervarietal hybrids. In decreasing order of preference, the dent type populations CMS 476, ZQP/B 103 and ZQP/B 101 and the flint type CMS 461, CMS 460, ZQP/B 104 and ZQP/B 102 are recommended to form composites.O objetivo deste trabalho foi investigar a heterose e seus componentes em 16 populações de milho de grãos brancos, de alta qualidade protéica.

    Full Text Available It is important to understand how changes in the product formulation can modify its characteristics. Thus, the objective of this study was to investigate the effect of whey protein concentrate (WPC on the texture of fat-free dairy desserts. The correlation between instrumental and sensory measurements was also investigated. Four formulations were prepared with different WPC concentrations (0, 1.5, 3.0, and 4.5 wt. (% and were evaluated using the texture profile analysis (TPA and rheology. Thickness was evaluated by nine trained panelists. Formulations containing WPC showed higher firmness, elasticity, chewiness, and gumminess and clearly differed from the control as indicated by principal component analysis (PCA. Flow behavior was characterized as time-dependent and pseudoplastic. Formulation with 4.5% WPC at 10 °C showed the highest thixotropic behavior. Experimental data were fitted to Herschel-Bulkley model. The addition of WPC contributed to the texture of the fat-free dairy dessert. The yield stress, apparent viscosity, and perceived thickness in the dairy desserts increased with WPC concentration. The presence of WPC promotes the formation of a stronger gel structure as a result of protein-protein interactions. The correlation between instrumental parameters and thickness provided practical results for food industries.É importante entender como as mudanças na formulação de um alimento podem afetar suas características.

    Full Text Available The objective of this work was to evaluate the levels of sodium monensin on lactating cows and their effects on productive performance and milk protein fraction composition. It was used 12 Holstein cows, distributed in four balanced 3 × 3 Latin squares, and fed three diets: one control without monensin, and two diets with monensin at the levels of 24 or 48 mg/kg DM added to the concentrate. Milk production was daily measured throughout the entire experimental period. The samples used for analysis of milk composition were collected on two alternated days from the two daily milking. Non-protein nitrogen, total nitrogen and non-casein nitrogen contents were directly evaluated in the milk, and casein, whey protein and true protein contents were indirectly determined. The use of monensin in the rations reduced dry matter and nutrient intake, especially when diet with 48 mg/kg of dry matter was given. The ration with 24 mg/kg of DM increased milk production, with or without correction, and also fat and lactose yield, and it improved productive efficiency. The levels of monensin in the ratios did not influence contents of milk crude protein, non-protein nitrogen, non-casein nitrogen, true protein, casein, casein/true protein ratio, whey protein, and of all those fractions expressed as percentage of crude protein. The utilization of monensin in the ratio at the dose of 24 mg/kg of DM influences positively the productive performance of lactating cows, and it does not influence the composition of milk protein fractions.Objetivou-se avaliar níveis de monensina sódica para vacas em lactação e seus efeitos no desempenho produtivo e na composição da fração protéica do leite.

    We present the case of an 18-year-old man, previously healthy, who presented with acute quadriplegia and respiratory failure. Physical examination was compatible with a high cervical anterior spinal cord lesion. We plan to evaluate the cause of such a neurological presentation in a healthy young man. American University Medical Center, Beirut, Lebanon. The patient underwent routine blood hematological and chemistry work-up, hypercoagulable profile studies, genetic profile for thrombophelias, radiographic studies of the brain and cervical cord, cerebrospinal analysis and extensive electrophyisological studies. Magnetic resonance imaging and magnetic resonance angiogram of the brain, carotid and intracranial vessels were normal. Cerebral angiography was normal. Magnetic resonance imaging of the cervical cord revealed lesion of the anterior segment of the cervical cord between C2 and C5 levels. Hypercoagulable profile studies were normal. Electrophysiological studies confirmed an isolated lesion of the descending cortico-spinal tracts. DNA analysis revealed the presence of a G20210A mutation-causing hyperprothrombinemia. We conclude that a G20210A mutation causing-hyperprothrombinemia can cause anterior spinal artery thrombosis and anterior spinal cord infarction with the resultant neurological deficits in otherwise healthy patients.

    Full Text Available Para melhorar a alimentação do pacu (Piaracatus mesopotamicus, é necessário conhecer o nível de aproveitamento dos ingredientes utilizados em suas dietas. Neste trabalho, inicialmente, foram analisados quatro métodos de coleta de fezes, em função da precisão e da versatilidade (dissecação, extrusão, Guelph e Guelph modificado, e o tempo entre as coletas de fezes nos sistemas de Guelph, por intermédio do coeficiente de digestibilidade da proteína bruta de uma dieta-referência para o pacu. Não houve diferença entre os métodos de coleta de fezes; já os intervalos de tempo das coletas apresentaram diferenças, podendo interferir nos resultados de digestibilidade da proteína. Em uma segunda etapa, para determinação dos coeficientes de digestibilidade da proteína e da energia de cinco concentrados protéicos de origem animal, cinco de origem vegetal e quatro energéticos, foram utilizadas rações elaboradas com 69,5% de uma dieta-referência, 30% do ingrediente teste e 0,5% de Cr2O3, utilizando o método de extrusão manual para a coleta de fezes. Os valores de digestibilidade da proteína da maioria dos alimentos apresentaram-se altos e não variaram estatisticamente, de 93,89 a 75,73% para o farelo de trigo e a farinha de penas, respectivamente. Entretanto, a farinha de sangue e a levedura apresentaram valores de digestibilidade da fração protéica significativamente inferiores (57,72 e 68,86%, respectivamente.

We did not find differences between all the tested standing modifications (except for the natural bipedal standing position in sways and COP velocity movements. With a prolonged period of waiting for a prosthesis fitting we can observe an enlarged asymmetry of body weight distribution between the legs and also a higher range of COP sway and velocity. CONCLUSIONS: In all measurements in patients with a transtibial amputation, our results show a greater loading on the sound limb compared to the prosthetic one. Faster prosthesis fitting decreases asymmetry from body weight distribution between both of the legs. The basic goal of achieving full value life in patients after lower limb amputation is a tendency towards early prosthesis fitting.

    Full Text Available The coat protein (CP gene of the potato virus Y strain "o" (PVY O was introduced into potato, cultivar Achat, via Agrobacterium tumefaciens-mediated transformation. Sixty three putative transgenic lines were challenged against the Brazilian strains PVY-OBR and PVY-NBR. An extremely resistant phenotype, against the two strains, was observed in one line, denominated 1P. No symptoms or positive ELISA results were observed in 16 challenged plants from this line. Another clone, named as 63P, showed a lower level of resistance. Southern blot analysis showed five copies of the CP gene in the extremely resistant line and at least three copies in the other resistant line. The stability of the integrated transgenes in the extreme resistant line was examined during several in vitro multiplications over a period of three years, with no modification in the Southern pattern was observed. The stability of the transgenes, the absence of primary infections and the relatively broad spectrum of resistance suggest that the extremely resistant line obtained in this work can be useful for agricultural purposes.O gene da capa protéica (CP do Potato virus Y estirpe "o", foi introduzido em batata cultivar Achat, via Agrobacterium tumefaciens.

    Full Text Available Cet article analyse les interactions socioculturelles d’acteurs multiples ayant des intérêts divergents en regard de la reconnaissance d’un espace naturel à titre d’aire protégée, plus particulièrement le Parc marin du Saguenay–Saint-Laurent (PMSSL, situé au Québec à l’embouchure de la rivière Saguenay. Compris dans le sens d’espace socialisé et investi de valeurs parfois contradictoires, ce territoire constitue le cas empirique sur lequel repose l’analyse des logiques d’acteurs. La perspective ici mise de l’avant repose à la fois sur une décision de l’État de créer et de mettre en valeur une aire marine ainsi que sur la participation active des collectivités territoriales dans la gestion du patrimoine environnemental et culturel lié à leur identité propre. Si la participation des communautés locales apparaît comme un élément essentiel et démocratique dans la reconnaissance d’un espace naturel protégé, il apparaît tout aussi capital de bien saisir la logique qui sous-tend les actions de l’État et du milieu. Les résultats empiriques montrent deux logiques d’action distinctes à l’œuvre, une logique classique de planification et implantation stratégique de l’état réservant une espace de participation programmée pour la communauté et une logique stratégique communautaire à caractère émergent, de portée moins englobante mais adaptable aux nouvelles réalités et contraintes gouvernementales. Les résultats peuvent être représentés sous forme d’un processus de gouvernance à l’œuvre, un caractérisé par une participation de base, mais un qui suggère qu’un processus plus hautement démocratique nécessiterait un plus haut degré de vigilance dans la perspective communautaire, suffisante pour produire une meilleure symétrie de pouvoir démocratique entre l’État.This paper analyzes the socio-cultural dynamic between multiple stakeholders with divergent interests

    Full Text Available OBJETIVO: duas marcas comerciais de resinas acrílicas ativadas quimicamente (RAAQ, uma de uso ortodôntico (Orto Cril® e outra de uso protético (Jet®, polimerizadas em presença e ausência de pressão, foram analisadas em relação ao conteúdo de monômero (MMA residual liberado em solução, em diferentes intervalos de tempo (0,083; 0,25; 1; 1,25; 2,17; 5; 9; 14 e 21 dias. METODOLOGIA: a espectroscopia de absorção no ultravioleta foi utilizada na análise de soluções aquosas de MMA, com concentrações conhecidas, visando a determinação de uma curva de calibração. Soluções aquosas contendo corpos-de-prova, confeccionados com as citadas RAAQ, foram também submetidas à análise por espectroscopia de absorção no ultravioleta. RESULTADOS E CONCLUSÕES: os resultados foram comparados aos dados da curva de calibração, visando estabelecer a concentração de MMA residual das amostras. Eles permitiram concluir que o nível de MMA residual liberado em solução foi mais elevado durante as primeiras 24 horas, havendo uma tendência à estabilização a partir desse período e que a resina acrílica de uso ortodôntico apresentou níveis mais elevados de MMA em solução do que a de uso protético, em ambas as condições de polimerização empregadas, com presença e ausência de pressão. Além disso, a presença de pressão, durante a polimerização das duas resinas, elevou a concentração de MMA em solução, não havendo, entretanto, efeito da interação entre as marcas das resinas e a presença e ausência de pressão na concentração de MMA em solução, medida ao longo do tempo. Porém, todas as três variáveis (tempo, resina e pressão foram significantes.AIM: Two comercial brands of auto polymerizing acrylic resins (one for orthodontics use, Orto Cril®, and the other for prosthetics use, Jet® were analyzed concerning the amount of methyl methacrilate (MMA monomer dissolved in solution, processed under and not under

Neste trabalho, uma massa alimentícia fresca funcional foi desenvolvida pela incorporação de Isolado Protéico de Soja (IPS e polidextrose, utilizando páprica como corante. O consumo de IPS pode contribuir para a diminuição dos níveis de colesterol, enquanto a polidextrose, funcionando como fibra, pode promover a redução de risco de câncer de cólon. A otimização da formulação foi realizada utilizando-se um delineamento fatorial completo 23, considerando como variáveis independentes os teores de: i IPS; ii polidextrose; e iii páprica. Os efeitos destas variáveis na qualidade da massa alimentícia foram avaliados em função das características físico-químicas (cor e teste de cozimento, textura instrumental e propriedades sensoriais. Na avaliação dos parâmetros físicos, observou-se que a cor instrumental da massa crua foi influenciada apenas pelo teor de páprica; já o tempo de cozimento (2,5 minutos, o aumento de massa (1,40 a 1,64% e a perda de sólidos (3,80 a 5,56% não foram influenciados pelos ingredientes utilizados; e a elasticidade (parâmetro da textura instrumental foi reduzida com o aumento do teor de polidextrose. Na avaliação sensorial da massa crua, o aumento na porcentagem de IPS e a redução na porcentagem de polidextrose afetaram positivamente a aceitação global e a intenção de compra; e os aumentos nas porcentagens de IPS e de páprica aumentaram a aceitação da cor. Na avaliação sensorial da massa cozida, observou-se que o IPS teve influência positiva sobre a textura, enquanto que a polidextrose e a páprica afetaram negativamente este parâmetro. Entretanto, na avaliação da intenção de compra da massa cozida, não houve influência dos ingredientes adicionados. Os percentuais ideais de adição de polidextrose, isolado protéico de soja e p

    Full Text Available Inibidores de tripsina representam uma estratégia de controle de insetos e, por isso, a identificação e caracterização desses inibidores são etapas muito importantes para que novas formas de controle de pragas sejam desenvolvidas. Os inibidores de tripsina atuam na digestão primária de proteínas e comprometem o processo digestivo por completo, reduzindo a disponibilidade de aminoácidos ao inseto. A incorporação de inibidores de tripsina na dieta de insetos-praga é uma forma de controle cuja eficácia foi verificada por diferentes autores. Este projeto foi conduzido a fim de se observar a eficiência de extratos de folhas de mamona na inibição "in vitro" de proteinases do tipo tripsina do bicho-mineiro do cafeeiro. Após testes realizados com os extratos de folhas de mamona não-fervidos e fervidos com e sem a adição de β-mercaptoetanol 0,2% (v/v e mediante precipitações com acetona, verificou-se que o inibidor é uma molécula termoresistente e não-protéica. Desta forma, iniciou-se um processo de purificação da molécula inibidora por meio de cromatografia de adsorção com posterior análise em espectrômetro de massas. Os resultados dos testes de inibição indicaram a presença de um inibidor de tripsina eficaz contra o bicho-mineiro do cafeeiro nos extratos de folhas de mamona capaz de inibir 2,48 + 0,15 UTI, o que representa aproximadamente 40% de inibição. Em testes realizados com tripsina bovina observou-se que o extrato de folhas de mamona não apresenta poder de inibição sobre essa enzima.Trypsin inhibitors stand for a strategy of insect control and, therefore, the identification and characterization of these inhibitors are very important steps for new forms of pest control to be developed. Trypsin inhibitors act in the primary digestion of proteins and endanger the digestive process wholly, reducing the availability of aminoacids to the insect.

Utilizou-se 3000 larvas distribuídas em 15 grupos, estocadas em condições controladas de cultivo, em um sistema de criação com reutilização de água, termoregulada. As rações testadas eram isoprotéicas com 35% de PB (proteína bruta e níveis energéticos variando entre 3075 e 3286kcal ED/kg, formuladas com fontes de origem animal, vegetal e pó de levedura Saccharomyces cerevisae. Agranulometria dos alimentos testados foi de 100 a 200mi, 200 a 400mi e 400 a 600mi para as três semanas experimentais, respectivamente. A distribuição do alimento foi feita a vontade entre 8 e 20 horas. No final deste experimento o tratamento T1, contendo figado bovino e levedura, resultou na maior taxa de sobrevivencia (61% apresentando diferença altamente significativa em relação aos demais tratamentos. Os tratamentos 2 (soja, levedura, 3 (soja, figado bovino, 4 (soja, milho e 5 (soja, carne, milho não diferiram significativamente entre si, apresentando baixas taxas de sobrevivência (1,17 a 10,19%. OT1 apresentou o maior comprimento total aos 21 dias, com media individual de 16,46mm, diferindo significativamente dos demais tratamentos. Nestas condições conclui-se que o pó de levedura juntamente com o fígado bovino em rações, proporcionou o melhor desempenho de larvas de jundiá Rhamdia quelen.The experiment was carried out to evaluate the survival and growth of catfish larvae Rhamdia quelen with different sources of protein during the first three weeks of life. Five treatments, with three replications, were tested.

Na necropsia, os girinos não apresentaram externamente nenhuma alteração aparente, no entanto, o fígado dos animais, em todos os níveis de proteína bruta, apresentou-se de cor palha e manchado. Na análise histopatológica, observaram-se fígados com rarefação e degeneração celular protéica, intestinos com colite e achatamento das microvilosidades; baço com hiperplasia linfocitária; coração sem nenhuma alteração; rins com glomerulonefrite e áreas de tubulonefroses; gastrite mononuclear e hiperplasia e hipertrofia dos linfonodos regionais. Em todos os órgãos, verificou-se depósito de hemossiderina. Essas lesões sugerem quadro degenerativo nutricional, com desenvolvimento de processos inflamatórios, se difundindo para todos os órgãos. Os resultados sugerem que os animais foram alimentados com rações com proteínas de baixo valor biológico, portanto, de má qualidade, o que comprometeu a sanidade e o desempenho dos animais. Estudos complementares são necessários para compreensão do comportamento bioquímico de rãs-touro na fase de girino visando à nutrição adequada desses animais.Necropsy and histological examination were made on bullfrog (Rana catesbeiana tadpoles fed commercial rations with 32, 36, 45 or 55% crude protein (CP to establish the relationship between dietary crude protein and health of the animal.

O hidrolisado de IPS foi produzido em sistema descontínuo, 5% de substrato, relação enzima/substrato 1/20, 6 h, 37°C, sob agitação. A plasteína foi produzida com 40% de substrato em solução aquosa, pH 7, 24 h a 37°C, sob repouso. Na caracterização química, foi verificada a distribuição dos pesos moleculares por meio de eletroforese (SDS-PAGE e cromatografia de exclusão molecular (CEM. A SDS-PAGE não permitiu a visualização das bandas tanto no hidrolisado quanto na plasteína. Na CEM o hidrolisado apresentou 5 frações de PM na faixa de 5,4 a 66,2 kDa e a plasteína com 2 frações de PM na faixa de 9,6 e 58,7 kDa. O escore químico de aminoácidos essenciais confirmou a presença dos aminoácidos sulfurados como limitantes, sendo obtidos os valores de 93,2 e 96,4% para o hidrolisado e plasteína, respectivamente. A modificação enzimática através da reação de síntese de plasteína mostrou ser um processo viável na produção de matéria-prima para formulações alimentares de uso em nutrição clínica e em outros sistemas, sendo necessária a suplementação de metionina quando utilizada como fonte exclusiva de proteína.The objective of this research was to characterize chemically the plastein produced from a pancreatic hydrolysate of soy protein isolate (SPI.

    Full Text Available O consumo de sobremesas lácteas tem apresentado importante crescimento nesta última década, justificado pelo progresso tecnológico em ingredientes e processos. Neste trabalho efetuou-se a caracterização físico-química e sensorial de sobremesas lácteas achocolatadas cremosas, nas quais o concentrado protéico de soro - CPS (3,0; 2,0 e 1,0% foi usado com o leite em pó integral (5,0; 6,0 e 7,0%, carragena (0,05; 0,15 e 0,25%, goma guar (0,25; 0,15 e 0,05%, chocolate em pó (2,8%, açúcar (11,5% e sorbato de potássio (0,08%. Os resultados mostram que é viável utilizar o CPS em substituição ao leite em pó, oferecendo um produto com menores teores de gordura e de sólidos totais, e maior teor de proteínas. O produto apresentou melhor qualidade nutricional, além da redução calórica, favorecendo seu consumo por pessoas preocupadas com a saúde. A sobremesa elaborada com 1,00% de CPS, 7,00% de leite em pó, 0,05% de carragena e 0,25% de goma guar foi considerada a melhor pelos provadores, com aceitabilidade acima do valor 4 (bom.The consumption of dairy desserts has boomed in the last few decades, due to the technological progress in the development of ingredients and processes. In this study the physicochemical and sensory characterization of creamy chocolate dairy desserts were carried out. Whey powder concentrate - WPC (3.0; 2.0 and 1.0% was used with whole milk powder (5.0; 6.0 and 7.0%, carrageenan (0.05; 0.15 and 0.25%, guar gum (0.25; 0.15 and 0.05%, cocoa powder (2.8%, sugar (11.5% and potassium sorbate (0.08%, according to the trial. The results showed that it is possible to use WPC, replacing whole milk powder, and therefore creating a product with low fat and total solids, and high protein content. The final product presented better nutritional quality, besides reduced caloric value, which favors the consumption by people concerned with health. The experimental dairy dessert prepared with 1.00% WPC, 7.00% whole milk

    Full Text Available O matrinxã (Brycon cephalus - Gunther, 1869, é uma espécie de peixe nativa da bacia Amazônica que tem despertado grande interesse entre pesquisadores e piscicultores de todo o Brasil. A crescente demanda pelo cultivo desta espécie em ambiente controlado se deve, principalmente, à sua pronta adaptação ao cativeiro e à aceitação de alimentos artificiais, tanto de origem vegetal quanto animal, ao lado do seu elevado valor comercial. Contudo, para ser um empreendimento comercial bem sucedido, o alimento a ser fornecido a esta espécie deve atender a suas necessidades em proteína e permitir elevados ganhos de peso em períodos curtos. O experimento foi conduzido na estação de aqüicultura da Embrapa Amazônia Ocidental. Foram testados cinco níveis de proteína bruta (16, 19, 22, 25 e 28% em dietas isocalóricas (EB = 390 kcal/100g em um delineamento experimental inteiramente casualizado com três repetições para cada tratamento. Os resultados obtidos após 210 dias de estudo mostraram que a dieta contendo 28 % de proteína bruta promoveu o maior ganho de peso, melhor conversão alimentar e mais alto crescimento corporal entre os níveis testados, indicando que este nível protéico atendeu satisfatoriamente às necessidades de proteína para esta espécie, nas condições deste experimento.Matrinxã (Brycon cephalus - Gunther, 1869 a native fish species from the Amazon basin, has been causing a great deal of interest among researchers and fish culturists all over Brazil. The rising demand for the culture of this species in controlled environment is mainly due, to its ready adaptation to captivity, the acceptance of manufactured feed made with either animal or plant ingredients, along with its high commercial value. However, for a successful commercial enterprise, feed must meet protein requirements of the fish to allow high weight gain in a short period. The experiment was carried out at Embrapa Amazônia Ocidental aquaculture

    Resultats anteriors mostraven que rates amb obesitat nutricional ("dieta de cafeteria") tenien un perfil metabòlic d'estalvi de nitrogen, mentre que pel model d'obesitat genètica (Zucker (fa/fa)) es suggeria un malbaratament de nitrogen. Es mostra una reducció en la taxa de recanvi d'alanina per l'animal sencer en el model d'obesitat nutricional, i un increment en el model d'obesitat genètica. La fracció anabòlica de la taxa és la responsable d'aquestes alteracions, suggerint perturbacions en...
