title: Evaluation of the combination of poly (Lactic-Co-Glycolic Acid) and polyisoprene (Cellprene®) materials: histological study in rats

description: Abstract Introduction The bone quantity and quality in implant dentistry is a highly relevant factor when it aims the use of implants and rehabilitation in patients. However, this availability is compromised in most cases, with the need to research new biomaterials, membranes and substances for more favorable regeneration. Objective: The aim of this study was to evaluate the response of bone neoformation in critical defects in rat calvaries using polymeric blend fiber scaffolds from Poly (Lactic-Co-Glycolic Acid) and Polyisoprene (Cellprene®). The project was approved by the Animal Experimentation Ethics Committee. Material and method In this study 36 rats (Rattus Norvegicus), variation albinus, Holtzman, adults were used. The animals had trichotomy in the region of the skull and the confection of bilateral circular bone defects with a diameter of 5 mm. The animals were divided into 3 groups: Group GC - defect without biomaterial placement, Group GCol - collagen scaffolds (Bio-Gide, from Geistlich Pharma Ag - Biomaterials), Group GPoli - polymeric blend fiber scaffolds from Poly (Lactic-Co-Glycolic Acid)-Polyisoprene. Each group was evaluated in 4 experimental periods (7, 15, 30 and 60 days). After these periods the animals were sacrificed and the pieces underwent routine laboratory procedures and paraffin embedding. Semi-serial sections were obtained and stained by hematoxylin and eosin technique for histometric and histological analysis. Histometric analysis was performed to evaluate the composition of repaired bone tissue (% Bone). The data obtained were statistically analyzed with a significance level of 95%. Result It was found that the GCol group presented greater defect filling in the 30 and 60 days periods compared to the GC and GPoli groups. Conclusion Polymer blend fiber scaffolds from Poly (Lactic-Co-Glycolic Acid) and Polyisoprene (Cellprene®) did not have advantages when used in critical defects.

title: Endodontic sealers and post-endodontic waiting time affect the bond strength of the fiber posts

description: Abstract Introduction The resistance adhesive of a fiber post can be affected by several factors, such as the endodontic sealer and post-endodontic waiting time. Objective The aim of this study was to evaluate the effect of different endodontic sealers and two different post-endodontic waiting times on the bond strength of fiber posts. Material and method Seventy-two bovine teeth were endodontically treated and filled using three endodontic sealers: eugenol-based, epoxy resin-based, or mineral trioxide aggregate-based. The specimens were stored at 37°C for 24 hours or for 30 months. After the respective storage times, the root canals were prepared for luting fiber posts using RelyX U200. Push-out tests and analysis of failures were performed. The push-out data were analyzed by two-way analysis of variance to compare the effects of the endodontic sealer and with the t-test to compare the effects of post-endodontic waiting time. Result The AH Plus sealer yielded the highest bond strength values at 30 months post-endodontics (11.26 Mpa) (p &lt; 0.05), however no had difference with Endofill sealer at the same time. Endofill and MTA Fillapex sealers did not differ significantly in their effects, irrespective of the post-endodontic waiting time. Conclusion In conclusion, the endodontic sealer used and post-endodontic waiting time affect the adhesive resistance of fiber posts. The adhesion increases significantly when the fiber post is cemented 30 months after the root canal filling, while the adhesion is reduced when cementing immediately after root canal treatment, in particular for eugenol-based endodontic sealers.

title: Stewardship-oriented Culture and Family Firm Performance: A Study on the Moderating Effects in an Emerging Economy

description: Abstract Prior literature has provided inconclusive evidence on the effects of family involvement in management (FIM) on family business (FB) performance. However, so far in the literature, there have been very few attempts to investigate FIM and family essence simultaneously as antecedents of FB performance. Therefore, we address this gap by studying how a stewardship-oriented culture (being a feature of FB essence) moderates the relationship between FIM and FB performance. We test our hypotheses with the Structural Equation Modeling technique using survey data in combination with archival data on a sample of 69 medium and large private Brazilian FBs. We find that a stewardship-oriented culture makes the relationship between a family CEO and FB performance weaker and observe that a stewardship has no moderating effect on the relationship between FIM and FB performance. These findings contradict prior literature on the beneficial role of stewardship in family-managed FB. Only in case of a nonfamily CEO, a stewardship-oriented culture positively moderates the relationship with FB performance. In addition, our study reveals a U-shaped nonlinear relationship between the level of FIM and FB performance, which is consistent with recent literature on the existence of faultlines derived from heterogeneous TMT and the impact on firm outcome.

title: Performance and sanitary aspects of female dairy calves fed on a diet with or without homeopathic medicines

description: The objective of this study was to evaluate the development of the body, the dry matter intake (DMI), feed conversion (FC) and some sanitary aspects of 12 female dairy calves which were fed with or without the use of homeopathic medicines, from birth to 120 days of age. Newborn crossbred heifers (3/4 Holstein x 1/4 Gyr) with live weight of 35.71 kg were distributed in a completely randomized design, with six replicates per treatment. During weaning (0 - 56 days old), the treatments consisted of milk, being 2 liters in the morning and 2 liters in the afternoon, with or without the addition of homeopathic medicines (5 g/animal/day FACTORS PRO(r), STRESS(r) and C&MC(r)) and concentrate ad libitum. In the postweaning period (57 - 120 days old), the animals received the same concentrate, added or not with the same homeopathic medicines limiting the intake in 3 kg/animal/day. The addition of homeopathic medicines to the diet did not affect (p &gt; 0.05) body development, DMI or FC in dairy calves. A reduction in allopathic drugs to control diarrhea and tick infestation was observed in animals that received homeopathic products. It was concluded that the use of homeopathic medicines did not affect body development, and reduced the number of animals treated with allopathic medicines.

title: Caprine Arthritis Encephalitis virus is detected in oocytes and uterine fluid by nested PCR and nested RT-PCR

description: Caprine arthritis-encephalitis (CAE) is an infectious disease caused by the caprine arthritis-encephalitis virus (CAEV), belonging to the lentivirus genus. The presence of the virus has been observed in the nervous system, respiratory tract and mammary gland, and also in the male and female genital tract. The objective of this study is to identify the virus in oocyte and uterine fluid of infected goats by molecular diagnostic techniques, in order to assess the possibility of CAEV transmission with reproduction. Thirteen infected goats were selected and submitted to euthanasia for the collection of the reproductive system, aspiration of the uterine fluid and dissection of ovaries for oocyte collection. In order to identify the CAEV in the collected material, in the protovirus and free forms, it was submitted to the nRT-PCR and nPCR techniques, respectively. As a result, it was observed that 53.8% of oocytes were positive to nRT-PCR, while only 9.1% were positive to nPCR. The nRT-PCR also identified the virus in the uterine fluid of 46.1% of the tested females. Even though the 13 goats had CAEV, 30.8% presented negative results in nPCR and nRT-PCR in all of the analyzed samples (oocyte and uterine fluid). This work concludes that nRT-PCR and nPCR can be used in the diagnosis of CAE for the analysis with oocytes and uterine fluid, and that the presence of CAEV in these materials points out to the risk of CAEV transmission through reproductive technologies used in females.

title: Aeromonas hydrophila in tilapia (Oreochromis niloticus) after the intake of aflatoxins

description: The objectives of this study were to assess the effect of the intake of aflatoxin on the development of tilapia and to evaluate the impact of inoculation with Aeromonas hydrophila on performance parameters, so these two individual tests were performed. One hundred and twenty fingerlings aged 35 days old, with mean weight of 1.55 ± 0.005 g and mean length of 5 cm were used in each test, distributed in 20 tanks. Each experimental unit consisted of a 60 L tank with six fingerlings. In the first experiment, increasing levels of aflatoxin (0.350, 0.757, 1.177 mg.kg feed-1) were used as treatments and, for the control group, a diet without aflatoxin was used in a completely randomized design with four treatments and five replicates. In the second experiment, a control group of Nile tilapia fingerlings was used and received a diet without aflatoxin, inoculated with saline solution (group 1) and Aeromonas hydrophila (group 2), as well as groups of animals fed on diets containing 0.350 mg.kg feed-1of aflatoxin (group 3), 0.757 mg.kg feed-1of aflatoxin (group 4) and 1.177 mg.kg feed-1of aflatoxin (group 5), and these groups were inoculated with Aeromonas hydrophila. The survival rate and the total length of fingerlings were influenced by the treatments (p &lt; 0.05). The synergistic action of aflatoxins and Aeromonas hydrophila was effective and caused the death of experimental fish, thus affecting feed conversion and length.

title: Effect of aqueous plant extracts on the fruit fly Ceratitis capitata (Wiedemann) (Diptera: Tephritidae)

description: The aim of this study was to evaluate the effect of vegetable extracts to control Ceratitis capitata. The treatments were aqueous extracts prepared with fresh and dry vegetables at a 20% w/v (weight plant/water volume) rate of chinaberry leaf, twig and fruit, rue leaf, garlic, and ginger. For the immature phase evaluation, each repetition consisted of a plaque with 20 larvae or 20 pupae, which were dipped in 1 mL of extract for 30 seconds. For the extract prepared with chinaberry dry fruits, concentrations of 0, 5, 10, 15, 10, and 25% w/v were evaluated. Analyses were made after five days by counting the number of dead larvae or pupae and the number of deformed adults. For the adult phase, only the extracts prepared with dried vegetables were assessed. Each repetition included a plastic jar containing a red plum fruit and a cotton roller soaked with 5 mL of extract. For each plastic container, three females and two males of C. capitatawere transferred. After two days, the assessment of adult mortality and fruit withdrawal, which were individualized, were carried out. After seven days, the amount of larvae developed in each fruit was counted. It was found that all extracts reduced the number of viable insects, especially the chinaberry one, which also had an effect on the adult phase. In the studied conditions, no extract had effects on the fertility of C. capitata females.

title: Biology and morphology of the shoot fly (Diptera: Lonchaeidae)

description: The aim of this study was to determine biological and morphological patterns of the male shoot fly, Neosilba perezi(Diptera: Lonchaeidae). Under laboratory conditions, the incubation period of eggs took two days, on average (viability of eggs: 55.5%). Bred on an artificial diet, based on cassava flour, the mean time of development of the newly hatched larvae to pupa formation occurred in 15 days, and the average pupal period took 23 days. Finally, the biological cycle, from egg to adult, lasted approximately 40 days. The eggs are white colored, have an elliptical form and are about 960 ± 5.30 µm long and 290 ± 1.30 µm large in the central region; the vermiform larvae, third instar, are milky white and are ± 10 mm long (3rd instar).
