Influência do desenho do implante na micromovimentação de implantes imediatos com carga imediata: análise multivariada em elementos finitos

The purpose of this paper was to evaluate the influence of different implant designs on the micromovements of immediately placed implants. CT-based finite element models comprising an upper central incisor socket and four commercially available internal connection implant designs (SIN SW®, 3i Certain®, Nobel ReplaceTM, and RN synOcta® ITI Standard) of comparable diameter and length were constructed. 50, 100 and 200N magnitude loads were applied over the implant. ANOVA at 95% level of significance was used to evaluate bone to implant relative displacement (micromovements). The implant design (68,80%) greatly influences the micromovement of immediately placed implants. However, the loading magnitude (68,80%) is the most important factor regarding the implant stability in this protocol.

Retorno à atividade reprodutiva de touro angus após fimose traumática com obliteração parcial da luz prepucial: relato de caso

The main disturbs affecting the genital segment of bulls are balanitis, phimosis and preputial injuries, abscesses or prolapses, resulting in decreased libido or mating ability. One case of traumatic phimosis with partial obliteration of preputial lumen is reported in Aberdeen Angus bull. During anamnesis, it was reported that the animal was unable to expose the penis and presented increased penile and preputial volume of unknown etiology after being submitted to a libido test. During clinical examination, a firm preputial mass of 15 cm in diameter was observed in the middle third of the prepuce and stenosis of preputial lumen was detected approximately 17 cm from the preputial orifice. Reconstructive surgery was the chosen therapy, with amputation of the affected foreskin portion. A skin segment of about 12 cm and affected mucosal portion were removed. Postoperative therapy consisted of dressing with chlorhexidine digluconate based ointment, povidone iodine and topical insect repellent (cypermethrin and carbamyl), systemic antibiotic therapy with benzathine penicillin (30,000 IU / kg, repeated after 48 hours) and anti-inflammatory therapy with flunixin meglumine (2 , 0 mg / kg SID) for three days. After twenty days, semen was collected by massage of the accessory glands. The ejaculate volume was 3 mL, with 200x106 spermatozoa / mL, white color, "suis generis" odor, 88% of motile sperm, 64% of progressively motile sperm and 82% of rapid sperm. Thus, the chosen surgical treatment was effective to correct the pathology and reintroduce the animal into reproductive activity

Orquiepididimite causada por Corynebacterium sp e Proteus mirabilis em cordeiro da raça Lacaune: relato de caso

Orchiepididymitis is the inflammation of both, testis and epididymis and may be caused by microbial agents such as Brucella ovis. Thus, the aim of the present report is to present a case of orchiepididymitis in a Lacaune ram with unilateral testicular enlargement. Ultrasonography of the testis revealed the presence of a circular hypoechogenic structure adjacent to the testicular parenchyma. Corynebacterium sp was isolated from the surgically removed testis. Two months after removal of the affected testis, the animal returned to the Veterinary Hospital due to an enlargement of the remaining testis. A new ultrasonographic exam revealed the presence of abscesses in the testicular parenchyma and periorchitis. After orchiectomy, Proteus mirabilis was isolated from the material.

MATHEMATICAL ANALYSIS OF MAXIMUM POWER GENERATED BY PHOTOVOLTAIC SYSTEMS AND FITTING CURVES FOR STANDARD TEST CONDITIONS

The rural electrification is characterized by geographical dispersion of the population, low consumption, high investment by consumers and high cost. Moreover, solar radiation constitutes an inexhaustible source of energy and in its conversion into electricity photovoltaic panels are used. In this study, equations were adjusted to field conditions presented by the manufacturer for current and power of small photovoltaic systems. The mathematical analysis was performed on the photovoltaic rural system I- 100 from ISOFOTON, with power 300 Wp, located at the Experimental Farm Lageado of FCA/UNESP. For the development of such equations, the circuitry of photovoltaic cells has been studied to apply iterative numerical methods for the determination of electrical parameters and possible errors in the appropriate equations in the literature to reality. Therefore, a simulation of a photovoltaic panel was proposed through mathematical equations that were adjusted according to the data of local radiation. The results have presented equations that provide real answers to the user and may assist in the design of these systems, once calculated that the maximum power limit ensures a supply of energy generated. This real sizing helps establishing the possible applications of solar energy to the rural producer and informing the real possibilities of generating electricity from the sun.

Production of human factor VIII-FL in 293T cells using the bicistronic MGMT(P140K)-retroviral vector

Hemophilia A is the most common X-linked bleeding disorder; it is caused by deficiency of coagulation factor VIII (FVIII). Replacement therapy with rFVIII produced from human cell line is a major goal for treating hemophilia patients. We prepared a full-length recombinant FVIII (FVIII-FL), using the pMFG-P140K retroviral vector. The IRES DNA fragment was cloned upstream to the P140K gene, providing a 9.34-kb bicistronic vector. FVIII-FL cDNA was then cloned upstream to IRES, resulting in a 16.6-kb construct. In parallel, an eGFP control vector was generated, resulting in a 10.1-kb construct. The 293T cells were transfected with these constructs, generating the 293T-FVIII-FL/P140K and 293T-eGFP/P140K cell lines. In 293T-FVIII-FL/P140K cells, FVIII and P140K mRNAs levels were 4,410 (+/- 931.7)- and 295,400 (+/- 75,769)-fold higher than in virgin cells. In 293T-eGFP/P140K cells, the eGFP and P140K mRNAs levels were 1,501,000 (+/- 493,700)- and 308,000 (+/- 139,300)-fold higher than in virgin cells. The amount of FVIII-FL was 0.2 IU/mL and 45 ng/mL FVIII cells or 4.4 IU/mu g protein. These data demonstrate the efficacy of the bicistronic retroviral vector expressing FVIII-FL and MGMT(P140K), showing that it could be used for producing the FVIII-FL protein in a human cell line.

A biomecânica e a produção do conhecimento em fisioterapia: levantamento baseado nos anais do congresso brasileiro de biomecânica

O aumento gradual da participação da comunidade acadêmica da Fisioterapia nas edições do Congresso Brasileiro de Biomecânica (CBB) é notório. Os Anais do CBB passaram a ser importantes veículos para a divulgação científica em Fisioterapia no Brasil; porém, a caracterização dessa produção ainda não foi feita. O objetivo do presente estudo foi realizar um levantamento bibliográfico dos estudos em Fisioterapia publicados nas edições dos Anais do CBB, desde a primeira edição em 1992 (Anais do IV CBB) até a edição publicada em 2009 (Anais do XIII CBB), a fim de identificar quais especialidades da Fisioterapia têm aplicado o conhecimento em Biomecânica no contexto clínico e/ou científico, além de caracterizar o tipo de pesquisa que se tem desenvolvido. Seis revisores independentes levantaram os estudos pertencentes à área da Fisioterapia e coletaram informações de maneira padronizada através de questionários. Os resultados evidenciaram um grande crescimento da participação das diferentes áreas da Fisioterapia ao longo das dez edições do CBB. Embora os dados sejam positivos em relação à ampliação das pesquisas em Biomecânica, verificou-se uma carência da utilização dos recursos biomecânicos para avaliar efeitos de intervenções em pacientes. Dessa forma, recomenda-se que mais estudos sejam conduzidos em contextos clínicos e com acompanhamento longitudinal, de modo a ampliar a aplicação prática das ferramentas biomecânicas no campo da intervenção, bem como aperfeiçoar a avaliação em Fisioterapia.
