Effect of crown-to-implant ratio on peri-implant stress: a finite element analysis

The aim of this study was to evaluate stress distribution in the fixation screws and bone tissue around implants in single-implant supported prostheses with crowns of different heights (10,12.5, 15 mm crown-to-implant ratio 1:1, 1.25:1, 1.5:1, respectively). It was designed using three 3-Dmodels. Each model was developed with a mandibular segment of bone block including an internal hexagon implant supporting a screw-retained, single metalceramic crown. The crown height was set at 10, 12.5, and 15 mm with crown-to-implant ratio of 1:1, 1.25:1, 1.5:1, respectively. The applied forces were 200 N (axial) and 100 N (oblique). The increase of crown height showed differences with the oblique load in some situations. By von Mises'criterion, a high stress area was concentrated at the implant/fixation screw and abutment/implant interfaces at crown-to-implant ratio of 1:1, 1.25:1, 1.5:1, respectively. Using the maxiinum principal criteria, the buccal regions showed higher traction stress intensity, whereas the distal regions showed the largest compressive stress in all models. The increase of C/I ratio must be carefully evaluated by the dentist since the increase of this C/I ratio is proportional to the increase of average stress for both screw fixation (C/I 1:1 to 1:1.25 ratio = 30.1% and C/I 1:1 to 1 :1.5 ratio = 46.3%) and bone tissue (C/I 1:1 to 1:1.25 ratio = 30% and C/I 1:1 to 1:1.5 ratio = 51.5%).

Measurement of differential cross sections for the production of a pair of isolated photons in pp collisions at root s=7TeV

A measurement of differential cross sections for the production of a pair of isolated photons in proton-proton collisions at root s = 7 TeV is presented. The data sample corresponds to an integrated luminosity of 5.0 fb(-1) collected with the CMS detector. A data-driven isolation template method is used to extract the prompt diphoton yield. The measured cross section for two isolated photons, with transverse energy above 40 and 25 GeV respectively, in the pseudorapidity range vertical bar eta vertical bar < 2.5, vertical bar eta vertical bar (sic) [1.44, 1.57] and with an angular separation Delta R > 0.45, is 17.2 +/-0.2 (stat) +/-1.9 (syst) +/- 0.4 (lumi) pb. Differential cross sections are measured as a function of the diphoton invariant mass, the diphoton transverse momentum, the azimuthal angle difference between the two photons, and the cosine of the polar angle in the Collins-Soper reference frame of the diphoton system. The results are compared to theoretical predictions at leading, next-to-leading, and next-to-next-to-leading order in quantum chromodynamics.

Avaliação da biocompatibilidade de dois adesivos dentinários pelo estudo das reações teciduais em conjuntivo de ratos

The biocompatibility of two dentin adhesives (Scotchbond MultiPurpose- 3M and Optibond Multi-Use - Kerr) was evaluated in rats subcutaneous connective tissue implants. Polyethylene tubes filled with the adhesives were surgically implanted into the dorsal subcutaneous tissues of rats. The tubes were left implanted for periods of 14, 30, 60 and 84 days, following wich the animais were killed and the implants, together with the surrounding tissue, were excised. The specimens were then fixed in 10 per cent formalin, sectioned serially and stained with hematoxylin and eosin and then, examined by light microscopy. After 14 and 30 days the tubes were surrounded by a mild to moderate inflammatory infiltration. After 60 and 84 days microscopic examination revealed the formation of a connective tissue capsule around each tube. The microscopic examination of the biopsy specimens allowed to conclude that: a) both dentin adhesives are considered biologically acceptable when placed in contact with rats subcutaneous connective tissue; b) in the observation period of 30 days there were moderate tissue reaction to the Optibond Multi-Use -light cure- (Kerr); c) after 60 and 84 days the use of both dentine adhesives did not interfere in the healing of the surrounding connective tissue

Efeito da modificação atmosférica em goiabas var. Paluma na redução de danos mecânicos em pós-colheita

In the postharvest management, the fruits can be exposed to injuries that depreciated the quality and the shelf life. Thus, it was evaluated the modified atmosphere effects on guavas var. Paluma subjected to different mechanical damages. Once harvested, the fruits were selected, sanitized and submitted to the treatments T1 (control) - without injuries or packaging in bags of low density polyethylene (LDPE); T2 - without injuries + LDPE bags; T3 - damage by fall of 1 m + LDPE bags; T4 - damage by compression of 9 N + LDPE bags; T5 - damage by fall of 1 m + damage by compression of 9 N + LDPE bags and T6 - damage by fall of 1 m + damage by compression of 9 N without LDPE bags. The treatments were kept in cold storage at 10 ± 1 o C and 94 ± 2% de R.H. The analysis of CO2/ethylene production, enzymatic activity, total and soluble pectins, pulp firmness, titratable acidity (TA), soluble solids (SS), reducing sugars and ascorbic acid were performed every 10 days of refrigeration, and an additional day outside cold storage (22 ± 1o C and 75 ± 3% R.H.) for 30 days. Guavas packed in LDPE bags, not subject to mechanical damage, presented the best quality standards. The fruits suffered only one kind of damage, when packaged, presented satisfactory pattern compared to the fruits without package and not exposed to any mechanical damages. Applying the two kinds of damages, the LDPE packaging was not adequate to decrease the metabolic rate of these fruits, making them unfit for marketing.

Prediction of apparent protein digestibility of ingredients and diets by in vitro pH-stat degree of protein hydrolysis with species-specific enzymes for juvenile Pacific white shrimp Litopenaeus vannamei

Aquafeed production faces global issues related to availability of feed ingredients. Feed manufacturers require greater flexibility in order to develop nutritional and cost-effective formulations that take into account nutrient content and availability of ingredients. The search for appropriate ingredients requires detailed screening of their potential nutritional value and variability at the industrial level. In vitro digestion of feedstuffs by enzymes extracted from the target species has been correlated with apparent protein digestibility (APD) in fish and shrimp species. The present study verified the relationship between APD and in vitro degree of protein hydrolysis (DH) with Litopenaeus vannamei hepatopancreas enzymes in several different ingredients (n = 26): blood meals, casein, corn gluten meal, crab meal, distiller`s dried grains with solubles, feather meal, fish meals, gelatin, krill meals, poultry by-product meal, soybean meals, squid meals and wheat gluten. The relationship between APD and DH was further verified in diets formulated with these ingredients at 30% inclusion into a reference diet. APD was determined in vivo (30.1 +/- 0.5 degrees C, 32.2 +/- 0.4%.) with juvenile L vannamei (9 to 12 g) after placement of test ingredients into a reference diet (35 g kg(-1) CP: 8.03 g kg(-1) lipid; 2.01 kcal g(-1)) with chromic oxide as the inert marker. In vitro DH was assessed in ingredients and diets with standardized hepatopancreas enzymes extracted from pond-reared shrimp. The DH of ingredients was determined under different assay conditions to check for the most suitable in vitro protocol for APD prediction: different batches of enzyme extracts (HPf5 or HPf6), temperatures (25 or 30 degrees C) and enzyme activity (azocasein): crude protein ratios (4 U: 80 mg CP or 4 U: 40 mg CP). DH was not affected by ingredient proximate composition. APD was significantly correlated to DH in regressions considering either ingredients or diets. The relationships between APD and DH of the ingredients could be suitably adjusted to a Rational Function (y = (a + bx)/(1 + cx + dx2), n = 26. Best in vitro APD predictions were obtained at 25 degrees C, 4 U: 80 mg CP both for ingredients (R(2) = 0.86: P = 0.001) and test diets (R(2) = 0.96; P = 0.007). The regression model including all 26 ingredients generated higher prediction residuals (i.e., predicted APD - determined APD) for corn gluten meal, feather meal. poultry by-product meal and krill flour. The remaining test ingredients presented mean prediction residuals of 3.5 points. A model including only ingredients with APD>80% showed higher prediction precision (R(2) = 0.98: P = 0.000004; n = 20) with average residual of 1.8 points. Predictive models including only ingredients from the same origin (e.g., marine-based, R(2) = 0.98; P = 0.033) also displayed low residuals. Since in vitro techniques have been usually validated through regressions against in vivo APD, the DH predictive capacity may depend on the consistency of the in vivo methodology. Regressions between APD and DH suggested a close relationship between peptide bond breakage by hepatopancreas digestive proteases and the apparent nitrogen assimilation in shrimp, and this may be a useful tool to provide rapid nutritional information.
