Rank protein immunolabeling during bone-implant interface healing process

The purpose of this paper was to evaluate the expression of RANK protein during bone-healing process around machined surface implants. Twenty male Wistar rats, 90 days old, after having had a 2 mm diameter and 6 mm long implant inserted in their right tibias, were evaluated at 7, 14, 21, and 42 days after healing. After obtaining the histological samples, slides were subjected to RANK immunostaining reaction. Results were quantitatively evaluated. Results. Immunolabeling analysis showed expressions of RANK in osteoclast and osteoblast lineage cells. The statistical analysis showed an increase in the expression of RANK in osteoblasts at 7 postoperative days and a gradual decrease during the chronology of the healing process demonstrated by mild cellular activity in the final stage (P < .05). Conclusion. RANK immunolabeling was observed especially in osteoclast and osteoblast cells in primary bone during the initial periods of bone-healing/implant interface.

Error Upper Bounds for a Computational Method for Nonlinear Boundary and Initial-Value Problems

This work develops a computational approach for boundary and initial-value problems by using operational matrices, in order to run an evolutive process in a Hilbert space. Besides, upper bounds for errors in the solutions and in their derivatives can be estimated providing accuracy measures.

Influence of the initial condition in equilibrium last-passage percolation models

In this paper we consider an equilibrium last-passage percolation model on an environment given by a compound two-dimensional Poisson process. We prove an L-2-formula relating the initial measure with the last-passage percolation time. This formula turns out to be a useful tool to analyze the fluctuations of the last-passage times along non-characteristic directions.

An initial proposal for PDP of smes developing hospital furniture

A large percentage of the industrial SMEs has an organizational structure for product development too far from the adequate practices and models, elaborated by renowned authors with expertise in the theme of product development. On the other hand, the authors state that SMEs obtain considerable advantages by adopting a model of product development process (PDP) management. Healt is one of the most innovative sectors in the world, and countries like Brazil and Colombia are transitioning from a system that cares for contagious infecttions diseases where the drug product is the main form of treatment - to a system that cares for chronic degenerative conditions - where the equipment, including hospital furniture, has more relevance to the treatment. This change is offering better opportunities of specialized markets to hospital furniture SMEs that adopt an adquate PDF model. The present study proposes a first outline of a model of PDP management for industrial metal-mechanical SMEs that develop and manufacture hospital furniture, from a review of models proposed for great mechanical area.

Enteric coated mucoadhesive micropellets in rotary agglomeration process for wet spheronization

In this work a generally applicable method for the preparation of mucoadhesive micropellets of 250 to 600µm diameter is presented using rotor processing without the use of electrolytes. The mucoadhesive micropellets were developed to combine the advantages of mucoadhesion and microparticles. It was possible to produce mucoadhesive micropellets based on different mucoadhesive polymers Na-CMC, Na-alginate and chitosan. These micropellets are characterized by a lower friability (6 to 17%) when compared to industrial produced cellulose pellets (Cellets®) (41.5%). They show great tapped density and can be manufactured at high yields. The most influencing variables of the process are the water content at the of the end spraying period, determined by the liquid binder amount, the spraying rate, the inlet air temperature, the airflow and the humidity of the inlet air and the addition of the liquid binder, determined by the spraying rate, the rotor speed and the type of rotor disc. In a subsequent step a fluidized bed coating process was developed. It was possible to manifest a stable process in the Hüttlin Mycrolab® in contrast to the Mini-Glatt® apparatus. To reach enteric resistance, a 70% coating for Na-CMC micropellets, an 85% for chitosan micropellets and a 140% for Na-alginate micropellets, based on the amount of the starting micropellets, was necessary. Comparative dissolution experiments of the mucoadhesive micropellets were performed using the paddle apparatus with and without a sieve inlay, the basket apparatus, the reciprocating cylinder and flow-through cell. The paddle apparatus and the modified flow-through cell method turned out to be successful methods for the dissolution of mucoadhesive micropellets. All dissolution profiles showed an initial burst release followed by a slow release due to diffusion control. Depending on the method, the dissolution profiles changed from immediate release to slow release. The dissolution rate in the paddle apparatus was mainly influenced by the agitation rate whereas the flow-through cell pattern was mainly influenced by the particle size. Also, the logP and the HLB values of different emulsifiers were correlated to transfer HLB values of excipients into logP values and logP values of API´s into HLB values. These experiments did not show promising results. Finally, it was shown that manufacture of mucoadhesive micropellets is successful resulting in product being characterized by enteric resistency combined with high yields and convincing morphology.

Measurement of the e + e - pi + pi - pi + pi - cross section using initial state radiation at BABAR

One of the most precisely measured quantities in particle physics is the magnetic moment of the muon, which describes its coupling to an external magnetic field. It is expressed in form of the anomalous magnetic moment of the muon a_mu=(g_mu-2)/2 and has been determined experimentally with a precision of 0.5 parts per million. The current direct measurement and the theoretical prediction of the standard model differ by more than 3.5 standard deviations. Concerning theory, the contribution of the QED and weak interaction to a_mu can be calculated with very high precision in a perturbative approach.rnAt low energies, however, perturbation theory cannot be used to determine the hadronic contribution a^had_mu. On the other hand, a^had_mu may be derived via a dispersion relation from the sum of measured cross sections of exclusive hadronic reactions. Decreasing the experimental uncertainty on these hadronic cross sections is of utmost importance for an improved standard model prediction of a_mu.rnrnIn addition to traditional energy scan experiments, the method of Initial State Radiation (ISR) is used to measure hadronic cross sections. This approach allows experiments at colliders running at a fixed centre-of-mass energy to access smaller effective energies by studying events which contain a high-energetic photon emitted from the initial electron or positron. Using the technique of ISR, the energy range from threshold up to 4.5GeV can be accessed at Babar.rnrnThe cross section e+e- -> pi+pi- contributes with approximately 70% to the hadronic part of the anomalous magnetic moment of the muon a_mu^had. This important channel has been measured with a precision of better than 1%. Therefore, the leading contribution to the uncertainty of a_mu^had at present stems from the invariant mass region between 1GeV and 2GeV. In this energy range, the channels e+e- -> pi+pi-pi+pi- and e+e- -> pi+pi-pi0pi0 dominate the inclusive hadronic cross section. The measurement of the process e+e- -> pi+pi-pi+pi- will be presented in this thesis. This channel has been previously measured by Babar based on 25% of the total dataset. The new analysis includes a more detailed study of the background contamination from other ISR and non-radiative background reactions. In addition, sophisticated studies of the track reconstruction as well as the photon efficiency difference between the data and the simulation of the Babar detector are performed. With these auxiliary studies, a reduction of the systematic uncertainty from 5.0% to 2.4% in the peak region was achieved.rnrnThe pi+pi-pi+pi- final state has a rich internal structure. Hints are seen for the intermediate states rho(770)^0 f_2(1270), rho(770)^0 f_0(980), as well as a_1(1260)pi. In addition, the branching ratios BR(jpsi -> pi+pi-pi+pi-) and BR(psitwos -> jpsi pi+pi-) are extracted.rn
