Osseointegrated implants have specific nature distinguish them from natural teeth making them more susceptible to the efforts generated by mastication. The absence of periodontal ligament, which absorbs the masticatory forces and allows the movement of the teeth interfere with the reception of occlusal loads and therefore the predictability of implants. In the boneimplant interface did not occur the phenomena of dissipation of impact, even the movement induced. Thus, during planning and installation of implant prosthesis, the type and characteristics of occlusal pattern adopted should be established with criteria to be no grounds for future failures. In this regard we highlight the occlusal overload generated by several reasons like the presence of premature contacts, interference during motion excursive, deleterious habits and inappropriate extensions on cantilevers. Thus, the objective is to provide a review of the literature regarding the importance of occlusion in oral rehabilitation with implants. Factors to be considered in establishing a favorable occlusion, consistent with prostheses on implants will be described

In part I of this article, the factors related to the establishment of a favourable occlusion for the implant prosthodontics as well as its real importance in this kind of rehabilitation were showed up. However, it is known that the occlusal characteristics adopted in implant prosthodontics show specific patterns which must be different between each other in accordance to the type of prosthesis installed. The objective of the second part of this work is to present to the reader, by a literature review, those characteristics, justifying the reason because they must be associated to specific kind of prosthesis for favor the treatment established.

Cleft lip and palate (CLL) is a very common craniofacial anomaly. The cleft is usually corrected with surgery which may fail resulting in velopharyngeal dysfunction (VPD). The use of palatal prosthesis is an alternative treatment for correcting both, CLP and VPD. This study evaluated anxiety symptoms expectations of subjects of both genders, with velopharyngeal dysfunction, referred to palatal prosthesis program for VPD treatment. In this cross sectional and descriptive study 30 subjects with velopharyngeal dysfunction, aged 15 to 64 years old (mean age of 28) were interviewed at the Hospital for Rehabilitation of Craniofacial Anomalies (HRAC). All subjects referred to the palatal prosthesis program at HRAC in the year of 2005 were considered for participation in the study but only the first 30 candidates were included. A questionnaire addressing expectation elaborated by the researcher and the Beck Scale on anxiety were used. All subjects showed expectation regarding speech modification. Changes in professional and affective aspects of their lives after changes in speech were obtained with palatal prosthesis were the most reported expectations. Subjects’ age and gender influenced anxiety levels significantly which were minimum across subjects. High levels of expectation were more frequent than anxiety in the sample population.

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

As xilanases são enzimas que hidrolisam as ligações 1,4-β-xilosídicas da xilana e que possuem potencial biotecnológico em vários processos industriais, como na clarificação de sucos e vinhos, na fabricação de pães, na produção de biocombustíveis e no tratamento das polpas celulósicas. Além disso, os produtos de hidrólise da xilana, xilooligossacarídeos, podem ser utilizados como ingredientes prebióticos, ou seja, ingredientes nutricionais não digeríveis que estimulam seletivamente a proliferação e a atividade de bactérias benéficas do cólon. O uso de enzimas microbianas nas indústrias se dá devido às suas diversas vantagens sobre os métodos químicos e à facilidade de obtenção do microrganismo. Assim, os objetivos deste trabalho foram: produzir e caracterizar parcialmente a xilanase de Aspergillus sp isolado de pó de café utilizado, purificar parcialmente a enzima produzida e analisar os produtos de hidrólise da xilana. O Aspergillus sp mostrou-se bom produtor de xilanase quando o pó de sabugo de milho foi utilizado como fonte de carbono e a xilanase produzida apresentou melhor atividade específica quando o período de cultivo foi de 168 horas. Os processos de precipitação de proteínas e diálise promoveram o aumento da atividade específica do extrato. A xilanase de Aspergillus sp apresentou pH e temperatura de máxima atividade semelhantes aos de produzidas por Aspergillus niger isolados de outras fontes. A hidrólise da xilana produziu xilose e xilooligossacarídeos. Além da xilanase, o fungo revelou ser produtor de outras proteínas que podem ser estudadas em pesquisas futuras.
