Características de população de profissionais do sexo e sua associação com presença de doença sexualmente transmissível

Este estudo teve como objetivo descrever a população de profissionais do sexo, considerando características sociodemográficas, antecedentes gineco-obstétricos e comportamentais, e verificar a associação com a presença de doença sexualmente transmissível. Trata-se de estudo epidemiológico e transversal, realizado com 102 mulheres profissionais do sexo. Os dados foram obtidos por meio de entrevista e exames padrão-ouro para diagnóstico das doenças de interesse. A média de idade das mulheres foi de 26,1 anos, sendo que a maioria tinha nove ou mais anos de aprovação escolar, era solteira e teve coitarca antes dos 15 anos. A prática de sexo oral nos parceiros foi citada por 90,2% das mulheres, 99% delas relataram fazer uso de preservativo no trabalho, apenas 26,3% com parceiros fixos e 42,2% usavam drogas ilícitas. Não houve associação entre fatores sociodemográficos, antecedentes gineco-obstétricos e fatores comportamentais com presença de doença sexualmente transmissível e isso pode ser decorrente da escolaridade e do fato da população estudada possuir características muito semelhantes, dificultando o aparecimento de tais associações.

Orbital Implants Insertion to Improve Ocular Prostheses Motility

The objectives of this study were, through a literature review, to point the differences between orbital implants and their advantages and disadvantages, to evaluate prosthesis motility after orbital implants are inserted, and to point the implant wrapping current risks. Sixty-seven articles were reviewed. Enucleation implants can be autoplastics or alloplastics and porous (including natural and synthetic hydroxyapatite [HA]) or nonporous (silicone). Hydroxyapatite is the most related in the literature, but it has disadvantages, too, that is, all orbital implants must be wrapped. Exposure of the porous orbital implant can be repaired using different materials, which include homologous tissue, as well as autogenous graft, xenograft, and synthetic material mesh. The most used materials are HA and porous polyethylene orbital implant. The HA implant is expensive and possibly subject corals to damage, different from porous polyethylene orbital implants. Porous implants show the best prosthesis motility and a minimum rate of implants extrusion. Implant wraps can facilitate smoother entry of the implant into the orbit and allow reattachment of extraocular muscles. They also serve as a barrier between the overlying soft tissue and the rough surface of the implant, protecting implants from exposure or erosion.

Influence of Ridge Inclination and Implant Localization on the Association of Mandibular Kennedy Class I Removable Partial Denture

The aim of this study was to evaluate the tendency of displacement of the supporting structures of the distal extension removable partial denture (DERPD) associated to the implant with different inclinations of alveolar ridge and implant localizations through a two-dimensional finite-element method. Sixteen mandibular models were fabricated, presenting horizontal, distally descending, distally ascending, or descending-ascending ridges. All models presented the left canine and were rehabilitated with conventional DERPD or implant-retained prosthesis with the ERA system. The models were obtained by the AutoCAD software and transferred to the finite-element software ANSYS 9.0 for analysis. A force of 50 N was applied on the cusp tips of the teeth, with 5 points of loading of 10 N. The results were visualized by displacement maps. For all ridge inclinations, the assembly of the DERPD with distal plate retained by an anterior implant exhibited the lowest requisition of the supporting structures. The highest tendency of displacement occurred in the model with distally ascending ridge with incisal rest. It was concluded that the association of the implant decreased the displacement of the DERPD, and the anterior positioning of the implant associated to the DERPD with the distal plate preserved the supporting structures for all ridges.

Effect of light-curing units on microleakage under dental composite resins

The aim of this study was to determine the effect of two light-curing units (QTH and LED) on microleakage of Class II composite resin restorations with dentin cavosurface margins. Twenty extracted mandibular first premolars, free of caries and fractures were prepared two vertical slot cavities in the occluso-mesial and -destal surfaces (2 mm buccal-lingually, 2 mm proximal-axially and cervical limit in enamel) and divided into 4 equal groups (n = 8): GI and GII: packable posterior composite light-activated with LED and QTH, respectively; GIII and GIV: micro-hybrid composite resin light-activated with LED and QTH, respectively. The composite resins were applied following the manufacturer's instructions. After 24 h of water storage specimens were subjected to thermocycling for a total of 500 cycles at 5 and 55A degrees C and the teeth were then sealed with impermeable material. Teeth were immersed in 0.5% Basic fuchsin during 24 h at room temperature, and zero to three levels of penetration score were attributed. The Mann-Whitney and Kruskal-Wallis tests showed significant statistically similar (P > 0.05) from GI to GII and GIII to GIV, which the GII (2.750) had the highest mean scores and the GIII and GIV (0.875) had lowest mean scores. The use of different light-curing units has no influence on marginal integrity of Class II composite resin restorations and the proprieties of composite resins are important to reduce the microleakage.

Prey choice by facultative predator larvae of Chrysomya albiceps (Diptera: Calliphoridae)

In this study we investigated predation rates on third instar larvae of Chrysomya putoria and C. megacephala by third instar larvae of C. albiceps in a two-choice situation. The highest predation rate occurred on C. putoria larvae and this result is compared to previous experiments, in which C. macellaria larvae were present. Our results suggest that, when C. macellaria is absent C. albiceps larvae attack more C. putoria than C. megacephala larvae. Prey choice decisions and its implications for introduced and native blowflies are discussed.

Topological charge screening and pseudoscalar glueballs

Topological charge screening in the QCD vacuum is found to provide crucial nonperturbative contributions to the short-distance expansion of the pseudoscalar (0-+) glueball correlator. The screening contributions enter the Wilson coefficients and are an indispensable complement to the direct instanton contributions. They restore consistency with the anomalous axial Ward identity and remedy several flaws in the 0-+ glueball sum rules caused by direct instantons in the absence of screening (lack of resonance signals, violation of the positivity bound and of the underlying low-energy theorem). The impact of the finite width of the instanton size distribution and the (gauge-invariant) renormalization of the instanton contributions are also discussed. New predictions for the 0-+ glueball mass and decay constant are presented.

Protein, methionine+cystine and lysine levels for Japanese quails during the production phase

An experiment was conducted at Faculdade de Medicina Veterinária e Zootecnia/Unesp - Botucatu for 168 days to evaluate the effects of protein, Met + Cys and lysine diet levels on egg production and egg quality of laying Japanese quails. Quails with 42 days of age were reared in a completely randomized design. There were 1,944 quails distributed in four replicates of 27 birds per pen, according to a factorial 3x3x2 with three crude protein levels (16, 18 and 20% CP), three Met + Cys levels (0.700; 0.875 and 1.050%) and two lysine levels (1.100 and 1.375%). Birds fed diets with 18 and 20% CP had higher feed intake and egg production than those fed diets with 16% CP. There was significant interaction (p<0.05) between protein and Met + Cys levels on egg weight. There was no effects (p>0.05) of the protein level on feed conversion per dozen eggs; however, improved feed conversion per egg mass was seen for birds fed diets with 20% CP compared to those fed diets with 16% and 18% CP. Protein and lipid percentage in the yolk increased when dietary protein level increased from 16 to 18%. Increasing Met + Cys from 0.700% to 0.875% reduced yolk protein percentage. Higher lipid percentage in the yolk was seen in eggs from quails fed diets with 1.050% Met + Cys, whereas 1.375% lysine in the diet of resulted in decreased egg production and egg mass, besides poorer feed conversion per dozen eggs and per egg mass.

Correlação linear e espacial entre o rendimento de grãos do feijoeiro e a resistência mecânica à penetração em um Latossolo Vermelho distrófico

A resistência mecânica à penetração apresentada pelo solo exerce grande influência sobre o desenvolvimento vegetal, uma vez que o crescimento das raízes, assim como o rendimento das culturas, varia de forma inversamente proporcional ao seu valor. No ano agrícola de 2001/2002, na Fazenda Experimental de Ensino e Pesquisa da Faculdade de Engenharia/UNESP - Campus de Ilha Solteira, foram analisados o rendimento de grãos do feijoeiro (PG) e a resistência mecânica à penetração (R), de um Latossolo Vermelho distrófico. O objetivo foi apurar diretrizes relacionadas com o aumento da produtividade agrícola em questão, estudando a correlação linear e a espacial entre a PG e a R. Foi instalada uma rede geoestatística para a coleta dos dados do solo e da planta, estabelecida com espaçamentos de 5 x 5 m e 2,5 x 2,5 m, que continham 120 pontos amostrais distribuídos numa área de 1.875 m². A correlação linear entre a PG e a R foi praticamente nula, uma vez que, dependendo das profundidades estudadas do solo, apresentou coeficientes de correlação (r) menores do que 0,20. A análise geoestatística apresentou boa estrutura de dependência espacial, tanto para a PG quanto para a R, quando analisadas isoladamente. Entretanto, a análise espacial conjunta de tais atributos apresentou-se inconsistente. Assim, com o aumento da resistência mecânica à penetração, em determinada região do solo ocorreu ora aumento, ora diminuição do rendimento de grãos do feijoeiro.
