Efeitos das vitaminas A e C em anastomoses intestinais de ratos tratados com corticosteróide

OBJETIVE: There is a need to clearly define the affect of A and C vitamines in the healing of intestinal anastomosis on individuals under corticosteroid treatment, and this is the objetive of this study. METHODS: Fifty Wistar rats weighing 247± 22g were randomly separated in five groups. They were observated in individual cages with water and standard food ad libitum. The anesthesia was done with sodium pentobarbital 20 mg/Kg, intraperitoneal. During seven days preoperative and seven days after surgery, the groups were submmited to the protocol: I-control; II-metilprednisolone IM; III- metilprednisolone + vitamine A; IV- metilprednisolone + vitamine C; V- metilprednisolone + Vit. A + Vit. C. An enterectomy (1cm) and anastomosis was done, using nylon 6-0. In the seventh postoperative day, the tensil strength of the anastomosis was measured and a representative sample of the healing tissue was fixed in formaline 10% to histopatologic study under hematoxilin-eosine Masson tricromic process. The data were analised by the t Student test, considering significance 0,05. RESULTS: The bursting pressure of anastomosis of the group I (control) had no difference when compared with V group (Vitamine A and C) ( p>0,05). The difference was statisticaly significant when the I and V groups were compared with the II, III and IV groups (p 0,05). The control group (I) had histopatologic score 142± 17, significantly shorter than group II - metilprednisolene - (95± 22). The difference was not significant when compared the control and the V group (Vitamin A and C), with the score (153± 15). CONCLUSION: the vitamin A and C, when used toghether, contributes to revert the deleterious effects of corticosteroid in the healing of intestinal anastomosis in rats.
Zur Relevanz manualtherapeutischer Untersuchungen von Patienten mit Beschleunigungsverletzungen der HWS1

Complaints which seldom can be associated to structural injuries often persist for many years after acceleration injuries. 2 case studies demonstrate the relevance of a differentiated manual therapeutic examination which aims to identify possible structural impairments and instability of the atlanto-occipital joint. The suspected instability was confirmed by functional MRT and the intraoperative diagnosis.
Adaptive Resource Allocation and Scheduling for Cognitive Radio MIMO-OFDMA Systems

In this paper, channel adaptive resource allocation and user scheduling problem for cognitive radio multiple-inputmultiple-output orthogonal frequency-division multiple access systems is investigated. Furthermore, stochastic approximation is employed to develop an on-line algorithm which is capable of adaptively learning the underlying channel distribution. The NP-hard combinatorial resource allocation and user scheduling problem is then solved through via the Lagrangian relaxation approach. Numerical results demonstrate the effectiveness of our proposed scheme.
Validity of Mechanical Power Output Measurement at Bench Press Exercise

Validity of Mechanical Power Output Measurement at Bench Press Exercise In sport training and rehabilitation practice, it is usual to use methods of mechanical muscle power output measurement, which are based mainly on indirect force measurement. The aim of this study was to verify the validity of indirect measurement for mechanical muscle power output with bench press exercise. As a criterion of validity, we selected a combination of kinematic and dynamic analyses. Ten men participated in this study. Average age of tested subjects was 28.0 ± 3.4 years. At mechanical power output measurement, these subjects lifted at maximum possible speed loads of 18, 26.5, 39.2 and 47.7 kg. Validity of mechanical power output measurement by means of a method using indirect force measurement was estimated using Spearmen's Correlation Coefficient. Factual significance of differences in average values of power output, force and velocity, measured by a method using indirect force measurement, in comparison to the selected criterion, was evaluated by means of effect of size. Power output measurement method using indirect force measurement showed lower values of force in relation to the criterion in the whole scope of selected loads. Velocity values in the whole scope of selected loads did not show any significant difference between the criterion and the verified method. The mechanical muscle power output measured by the method using indirect force measurement is lower in relation to the criterion, especially in the low scope of loads, where also validity rate was low (R = 0.5).
An Effective Cooperative Load Balancing Scheme for Heterogeneous Network

In this paper, we propose a cooperative load balancing scheme focusing on improving effective resource utilization and mitigate the co-channel interference across domains through fair resource allocation in heterogeneous network (Het-Net). We models the load balancing issue as an optimization problem for minimizing the effective resource utilization. Simulation results have demonstrated that the system effective resource utilization is significantly reduced through our proposed inter-domain load balancing scheme. It is also demonstrated that by incorporating the co-channel interference in the optimization process, the proposed scheme has great advantages in interference management of Het-Net.

A parallel algorithm for timing-driven global routing for standard cells

The timing-driven global routing problem is an extremely important and time consuming phase of any automated layout system. In this paper, by integrating high performance interconnection tree construction, wire-sizing, and switch-able segment channel optimization together, we propose an adaptive timing-driven global routing algorithm which minimizes the timing delay as well as circuit area. Our experiments on MCNC benchmarks show that our timing-driven global routing algorithm reduces the maximum path delays significantly from the global router TimberWolfSC. Based on this adaptive timing-driven global routing algorithm, a parallel algorithm on timing-driven global routing for standard cells is given. This algorithm has been implemented on an 8 processor IBM J-40 shared memory multi-processor by using the Message Passing Interface (MPI). Our experimental results show good speedup and circuit delay results for this parallel algorithm using MCNC benchmark circuits.
Public understanding of counsellors and counselling in Hong Kong

This paper describes the findings of a survey of public understanding of counselling in Hong Kong. The survey questions focused on experiences and preferences of counselling; perceived benefits and drawbacks of counselling; and accreditation and approachability of counsellors. The findings revealed that the majority of respondents did not know a counsellor, had not experienced counselling, and were not willing to do so. Half of the respondents were not willing to pay for a counselling session. This lack of appreciation also extended to other health and caring professions. The possible reasons for this finding are discussed. On a more positive note, respondents perceived numerous benefits of counselling, including personal assistance and support; problem solving; and helping to relieve emotional tension. Counsellors were regarded as approachable and effective. Most respondents reported that counsellors should be registered members of government-approved associations, and have undergraduate and professional training, which calls for more involvement of professional associations. Overall, our findings show that, whilst the public recognize the benefits of counselling and identify a need for it, there is limited understanding. This confirms the tough reality that the counselling profession in Hong Kong is still in an early stage of development and faces a number of challenges. The next step is to use our findings to identify opportunities and devise strategies to remedy some of these issues.
Performance and architectural features of segmented multiple bus system

The paper introduces a new class of bus-based systems called the Segmented Multiple Bus System (SMBS). The SMBS overcomes the architectural limitations of bus-based shared memory systems while maintaining their advantages in terms of high degree of fault tolerance, ease of expansion and ease of programming. In addition SMBSs are scalable; unlike conventional MBSs. Another interesting feature of the SMBS is that it supports wormhole routing which is traditionally used in direct network topologies. Using approximate mean value analysis, we evaluate performance in terms of processing efficiency and request response time. We show good scalability for the SMBS. The approach we adopt in developing the models is comprehensive in the sense that the models incorporate features of both direct and indirect networks. This makes our performance models easily adaptable to several other network topologies.
A Cell-Planning Model for HetNet with CRE and TDM-ICIC in LTE-Advanced

Heterogeneous Network (HetNet) in 3GPP is a technique to increase network capacity. In order to further increase network capacity, Cell Range Expansion (CRE) and Time Domain Multiplexing Inter-Cell Interference Coordination (TDM-ICIC) have been discussed for LTE-Advanced. Since the parameter values for CRE and TDM-ICIC have a huge effect on network capacity expansion, in this paper, a cell-planning model for the downlink in HetNet with CRE and TDM-ICIC is presented in order to find the minimum number of installed pico BSs under the constraint of covering all user data traffic. The constraint condition is formulated by using an overload indicator for the cases of between normal subframes and muted subframes, because different interference sources are considered for these subframes by adopting TDM-ICIC. The appropriate parameter values of not only CRE and TDM-ICIC but also the location, transmission power, and antenna tilt for each pico BS are determined. Cell planning is conducted for traffic distribution generated by reference to realistic traffic distribution by a greedy algorithm based on the proposed cell-planning model. The result shows that the solution algorithm finds a good approximate solution which covers all data traffic by installing one pico BS with CRE bias value = 8 dB and setting the muted subframe ratio = 0.2.
An approach for torus embedding

We propose a new approach to embed a given torus G into another given torus H. The approach is applicable to tori of arbitrary dimension and size. We also analyze the costs of embedding in terms of load, dilation and congestion. In the case that G and H are rings, the load is optimal and the congestion is one. In the case that G and H are multi-dimensional square tori, the embedding costs are as follows: the load is asymptotically optimal; the dilation (congestion) is one if the torus G has equal or greater (less, respectively) number of nodes than that of H. In addition, we show that the approach induces efficient simulation of parallel algorithms.
Antihypertensive and antioxidant potential of vanillic acid, a phenolic compound in l-NAME-induced hypertensive rats: A dose-dependence study

Abstract We investigated the antihypertensive and antioxidant potential of vanillic acid (VA) in Nω-Nitro-l-arginine methyl ester hydrochloride (l-NAME) – treated adult male albino Wistar rats. Treatment of rats with l-NAME (40 mg/kg Bw for 30 days) caused a sustained increase in systolic- (SBP) and diastolic blood pressure (DBP) and significantly decreased the concentration of nitrite/nitrate (NOx) in plasma as compared with that in the control. Rats treated with VA restored SBP and DBP to normal level and preserve the plasma NO metabolites concentration. Moreover, VA reduced lipid peroxidation products (thiobarbituric acid reactive substances, lipid hydroperoxides, conjugated dienes) and significantly restored enzymatic antioxidants (superoxide dismutase, catalase, and glutathione peroxidase), non-enzymatic antioxidants (vitamin C, vitamin E, and reduced glutathione) in the plasma. To assess the toxicity if any of VA treatment, hepatic and renal function markers were measured. Our results showed that the effect at a dose of 50 mg/kg Bw of VA was more pronounced than that of the other two doses, 25 and 100 mg/kg Bw. These results were supported by histopathology studies. We conclude that VA possesses an antihypertensive and antioxidant activity in l-NAME-induced hypertensive rats.
An architecture for solving boolean satisfiability using runtime configurable hardware

An architecture is proposed for a forward checking tree search which is used for solving satisfiability problems. In this design, the FPGA on-chip RAM feature is used to achieve a large improvement in density over a straightforward implementation using configurable logic blocks, enabling much larger problems to be solved. In addition, the boolean function to be satisfied is runtime configurable. A prototype implementation of the design operated successfully at 10 MHz for a 50 variable, 80 clause 3-SAT problem.
An experimental model of contact dermatitis: Evaluation of the oxidative profile of Wistar rats treated with free and nanoencapsulated clobetasol

Abstract Objective An experimental animal model of contact dermatitis (CD) was used to investigate the effects of free and nanoencapsulated clobetasol propionate on the skin and on the oxidative profile of liver tissue. Methods Female Wistar rats were divided into six groups, each containing eight rats. The first group, control (C), was sensitized with solid vaseline. Group 2, (CD), was sensitized with 5% NiSO4. Groups 3 and 4 were sensitized with 5% NiSO4 and treated with free (FC) and nanoencapsulated (NC) clobetasol (0.42 mg/g), respectively, daily for 5 days. Group 5 was treated with nanoencapsulated clobetasol (0.42 mg/g) on days 1, 3, and 5 (C135) and group 6 received a hydrogel containing empty nanoparticles (NP) daily for 5 days. Thiobarbituric acid reactive substances (TBARS), carbonyl levels, non-protein sulfhydryl groups (NPSH) and catalase activity were measured in liver homogenates. Results A significant increase was observed in the levels of TBARS, NPSH, and catalase activity for the groups CD and NP. Discussion Our results suggest that both NiSO4 sensitization and NP administration induced oxidation of cellular lipids and activated the antioxidant enzyme catalase to protect from this damage. These results also indicated that daily treatment with the free and nanoencapsulated clobetasol, as well as treatment with the nanoencapsulated clobetasol every other day, were able to prevent these redox alterations and protect against histological damage.
P14.67: Ultrasound estimation of fetal weight in prolonged pregnancy

Introduction: When performing fetal biometry measurements, the examiner occasionally has the impression that the sonographic estimation is less accurate due to technical limitations. Our objective was to evaluate the possible association between the examiners assessment of the measurement accuracy and the actual error between fetal weight estimation and actual birth weight. Methods: 186 women, within 10 days of delivery, were examined prospectively using fetal biometric measurements. Fetal weight estimates were calculated using Hadlock’s formula employing FL, AC and BPD. The sonographers were asked to give a subjective score to each measurement; one point if the quality of the measurement was technically good, two points if the measurement was of medium quality and three points if the measurement was of poor quality. The difference between the corrected sonographic fetal weight estimation and the actual birth weight was analyzed with respect to the scoring given by the examiner. Results: As shown in tables 1–3 for none of the three measured parameters did the perceived measurement accuracy predict the actual error in predicting birth weight.
The oxidative stress index increases among patients with hyperemesis gravidarum but not in normal pregnancies

Abstract Objective The etiology and pathogenesis of hyperemesis gravidarum (HG) is still undetermined and has been suggested to involve oxidative stress. We aimed to evaluate the status of oxidative stress in HG by measuring the levels of total oxidant status (TOS), total antioxidant status (TAS), and by calculating the oxidative stress index (OSI). Methods In a case–control trial, fasting morning blood samples of patients with HG (n = 41) and healthy pregnant women (n = 39) were collected for analysis of serum TOS and TAS values as well as for calculation of OSI according to the formula: OSI = TOS / TAS × 100. Results Serum TOS and TAS levels were similar in both groups. However, serum TAS levels were lower among HG patients compared to controls, which resulted in an increase in OSI (P = 0.025). Discussion The present study supports the role of systemic oxidative stress, reflected by an imbalance between the TOS and TAS, in patients with HG. Our findings distinguish the mechanism underlying oxidative stress to result from reduction of antioxidants rather than an increase in oxidants.
Peripheral mononuclear leukocyte DNA damage, plasma prolidase activity, and oxidative status in patients with benign prostatic hyperplasia

Abstract Objectives Prolidase plays a major role in collagen turnover, matrix remodeling, and cell growth. Benign prostatic hyperplasia (BPH) may be associated with an increased extracellular matrix deposition. Therefore, the present study was designed to investigate the plasma prolidase activity, oxidative status, and peripheral mononuclear leukocyte DNA damage in patients with BPH. Patients and methods Twenty-six male patients with BPH and 24 healthy male subjects were included in this study. Blood samples were collected from antecubital vein after an overnight fasting period, and the plasma was separated. Plasma prolidase activity, total antioxidant capacity (TAC), total oxidant status (TOS), and oxidative stress index (OSI) were determined. The peripheral lymphocyte oxidative DNA damage was determined using an alkaline single cell gel electrophoresis assay (comet assay). Results The plasma prolidase activity, TOS levels, OSI values, and peripheral mononuclear leukocyte DNA damage were significantly higher (P < 0.001), while the TAC levels were significantly lower (P < 0.001) in patients with BPH than controls. In BPH patients, the prolidase activity was significantly associated with TAC levels (r = −0.366, P < 0.05), TOS levels (r = 0.573, P < 0.001), and OSI (r = 0.618, P < 0.001) and peripheral mononuclear leukocyte DNA damage (r = 0.461, P < 0.001). Conclusions Our results showed that BPH might be associated with an increased oxidative stress, and also an increased plasma prolidase activity. Increased prolidase activity might play an important role in the etiopathogenesis and/or progression of BPH.
Ecallantide (DX-88), a plasma kallikrein inhibitor for the treatment of hereditary angioedema and the prevention of blood loss in on-pump cardiothoracic surgery

Background: Plasma kallikrein plays a major role in the contact (kallikrein–kinin) cascade producing bradykinin. Bradykinin is a vasodilator, which increases vascular permeability, activates inflammation and produces pain. Plasma kallikrein is also crosslinked to the coagulation system and the complement cascade. Objective: Ecallantide (DX-88) is a potent and specific inhibitor of plasma kallikrein. Ecallantide is a recombinantly produced and engineered small protein based on the first Kunitz domain of human tissue factor pathway inhibitor. It was identified through phage display technology. Methods: The search terms ‘ecallantide’, ‘DX-88’ and ‘hereditary angioedema’ were entered into Pubmed/Medline, ClinicalTrials and Google. Results/conclusion: At present, the drug is being studied for two major indications. First, the results for the treatment of hereditary angioedema are promising. Second, a prospective randomised multi-centre trial for the reduction of blood loss during on-pump cardiothoracic surgery will be terminated in October 2008.
