title: Caries lesion remineralization with fluoride toothpastes and chlorhexidine - effects of application timing and toothpaste surfactant

description: Abstract Habitual toothbrushing with fluoridated toothpaste followed by rinsing with antibacterial mouthwashes is a method to maintain good oral hygiene and to diminish the occurrence and severity of dental caries and periodontal disease. However, our understanding of how antimicrobial agents in mouthwashes affect fluoride-mediated caries lesion remineralization is still poor. Objective: The objectives of this in vitro study were a) to determine the effects of the waiting period of chlorhexidine (CHX) rinsing after fluoride toothpaste use and b) to further determine the effect of the type of toothpaste surfactant [sodium dodecyl sulfate (SDS) or cocamidopropyl betaine (CAPB)] on caries lesion remineralization associated with CHX rinsing. Material and Methods: Caries lesions were formed in bovine enamel specimens and assigned to 10 treatment groups (n=18) based on Vickers surface microhardness (VHN). Lesions were then pH-cycled for 10 days with daily regimen comprised of twice daily toothpaste slurry treatments (1150 ppm fluoride, with SDS or CAPB), followed by CHX solution treatments [0, 15, 30 or 60 minutes following slurry treatment or no CHX treatment (negative control)]. VHN was measured again and the extent of lesion remineralization calculated (∆VHN). Results: ∆VHN with SDS-toothpaste was significantly lower than with CAPB-toothpaste, indicating more remineralization for the CAPB-toothpaste. ∆VHN with 0-minute waiting time was significantly lower than with 30-minute waiting time and with negative control. Conclusions: The absence of CHX as an adjunct to fluoride toothpastes led to greater remineralization of enamel lesions compared with the immediate use of CHX treatment for both SDS- and CAPB-toothpastes. CAPB-toothpastes indicated significantly greater remineralization than SDS-toothpastes, and can be suggested for patients at high risk of caries. A 30-minute waiting time for CHX treatment is recommended after brushing.

title: Correlations between production and economic variables in dairy cows on a tropical pasture

description: ABSTRACT. The objective of this study was to evaluate correlations between production and economic variables of lactating cows on a tropical pasture. The experiment involved ten – Holstein × ¼ Dairy Gyr cows in the middle third of lactation at an average age of 70 ± 4.6 months and an average body weight of 400 ± 55.2 kg. Cows were supplemented with a concentrate feed with different supplement compositions aiming to promote alterations in the animal performance and economic responses. Data were analyzed statistically by Pearson correlations at the 0.95 probability level. No correlations were observed for fat and total solids with economic variables (p &gt; 0.05). Milk yield was positively correlated with (p &lt; 0.05), but had no correlation with FC or MRR (p &gt; 0.05). There were no correlations for milk yield with RC, FC, or MRR (p &gt; 0.05). Positive correlations were observed for fat corrected milk yield with GRSM and RMSC (p &lt; 0.05). Fat production (kg day‒1) was positively correlated with GRSM and RMSC (p &lt; 0.05). The gross revenue from the sale of milk and the revenue minus feed costs showed to be highly associated with production variables.

title: ‘Watercolour drawings’ - reflections on historical painted manuscripts techniques and materials identification.

description: ABSTRACT This paper aims to foment the terminological and conceptual discussion involved in the identification of techniques and materials applied to manuscripts, drawings and paintings, particularly produced during scientific expeditions in the 18th and the 19th centuries; it also analyzes other images from that time, regardless of their artistic status. The methodological approach is established on interdisciplinary interests of Social History, Art History, and Conservation Science. Specification of the inks used on paper, their application and preparation methods, as well as the distinction of the optical effects resulting from the different process, could avoid the widespread generalizations in the use of the expression “watercolor drawing”. Social and historical circumstances related to the production of the visual material could also help identifying the material qualities of graphic documents, and distinguishing among graffiti, china ink and watercolor drawings, and between body color and watercolor paintings. It is important to acknowledge that the use of materials and techniques was a painter’s social and historical choice made from many possibilities.

title: NEW ALKYL PHENOLS AND FATTY ACID PROFILE FROM OILS OF PULPED Spondias mombin L. SEED WASTES

description: Spondias mombin L. is a Brazilian tree belonging to the family Anacardiaceae and popularly known as “cajá”, the genus is well known by the various exotic fruit species such as “siriguela” (S. purpurea), “umbu” (S. tuberosa) and “umbu-cajá” (S. bahiensis). It presents commercial importance to the locals especially due the small juice fruit industries and the seeds are often discarded as waste after pulping. Despite the regional importance, even today there is little information on the chemical composition of these fruits. Thus, the dichloromethane extract of the waste seeds of S. mombin was subjected to different chromatographic fractionation allowing the isolation of a main triglyceride identified as 1,3-dioleoyl-2-linoleoyl glycerol, two new alkyl phenols named 1-hydroxyl-3-[(Z)-10’-octadecenyl]-benzene and 1-hydroxyl-3-[(Z)-10’-docosenyl] benzene, and a mixture of phytosteroids. The seed’s fatty acid profile and the cytotoxicity of the oils and isolated compounds were also determinated employing BST. The alkenylphenol mixture present some toxicity (CL50 215,4 µg mL-1) in this test.

title: Learning Based on Primary Health Care Cases in Brazilian Medical Schools

description: ABSTRACT This study aimed to assess community placement of studentsfrom Brazilian Medical Schools and the schools'integration of basic content intothe clinical curriculum through actual experience of clinical situations in primary health care. A structured questionnaire containing 26 pre-tested items was sent out initially by e-mail to the coordinators of160 medical courses recognized by the Ministry of Education (MEC) with at least one class of recent graduates. The selected schools and coordinators were identified from a list of ABEM (Brazilian Association of Medical Education) member institutions from May to October 2013. The questionnaires were answered by 108 coordinators in three different methods: by e-mail, by telephone interviewand in hard copy (face-to-face meetings) after signing the Informed Consent Form (TCLE). Data were tabulated and analyzed by descriptive statistics, with percentage distribution of the categorical variables, using thestatistical software packageEpi-InfoTM, version 7.1.4. 88% of thecoorindators reported that their school is striving to achieve curricular integration between basic, clinical and human sciences; 58.3% of them present integration through the problematization of clinical cases in primary care and 43.5% considerthe content to be partially integrated. All respondent schools follow the National Curriculum Guidelines of 2001 and 38.9% received inductive policy governmental aid. For 63.9% of the respondents,the curriculum is guided by the most prevalent health problems and 75.9% consider that the objectives are relevant to the population. A total of 86.1% foresee work withincross-functional teams and 56.5% of the schools integrate family physicians with other medical specialties. For 71.3%, activities in the local community increase social responsibility and 37% believe it may improve the distribution of future professionals. According to the coordinators, most medical schoolsare implementing basic and clinical curricular integration and 67.6% expressed the view that the strategies used for curricular integration at their medical schools are successful.

title: The social life of ‘Colchas’ and other Indo-Portuguese assets: Uses and value beyond trade (XVI-XVIII centuries)

description: ABSTRACT The aesthetic value of textiles, ceramics and furniture from Asia became a popular study subject in specific historiographical circles, especially in essays and monographic studies developed by art history specialists, often included in exhibition catalogues and other journals related to museum collections, artistic heritage, or restoration and conservation of private collections. However, despite the growing interest they arouse in certain historiographical circles, Asian objects are still seldom analyzed in their exact historical and social framework, i.e., as pieces with a functional use and a patrimonial value, as well as social and economic assets to display and preserve the individual memory and the memory of old and current Portuguese households. The prospect that will be highlighted in this article is the idea of an “India through the gates”, which includes the material infrastructures of both the daily life and the accumulation of assets inside 17th and 18th century households, particularly considering the Indian Colchas. Given the chronic shortage of textiles in the country, this prospect may represent the most intensive and wide ranged trading activity with the main textile export centers from central Europe to Portugal, in the 15th century, as a natural step in the pursue of Asian textiles. From a formal and plastic point of view, these textiles provided more sophisticated aesthetic solutions, especially after the arrival of the Portuguese in India and the strengthening of a transcultural and transcontinental network with multiple economic and cultural connections, throughout the 17th and 18th centuries.

title: Financial stress in the Brazilian economy during an inflation targeting regime

description: Abstract Financial crises that have occurred in recent decades brought new challenges for policymakers in developed and developing countries in order to include issues related to financial stability. This paper aimed to build a Financial Stress Index (FSI) to identify and characterize episodes of financial stress that affected the Brazilian economy during an inflation targeting regime. Five episodes of stress with a duration of greater or equal to three months were identified. Four of them were associated with crises that impacted the Brazilian economy: the economic confidence crisis (2002); crisis of subprime (2008); crisis in the euro zone (2011) and the political and economic crisis (2014). The instability in the foreign exchange and stock market enhanced the impact of major episodes of financial stresses on the Brazilian economy. Results showed that the F.S.I. can be a useful tool for the Brazilian Central Bank to identify such episodes which generate financial stress in the economy.

title: TECHNICAL VARIATION IN AFFIXING HAMSTRING GRAFTS TO THE TIBIA IN ACL RECONSTRUCTION

description: ABSTRACT Purpose: To present a technical variation in tibial fixation of quadruple hamstring grafts during anatomic reconstruction of the anterior cruciate ligament (ACL). The secondary purpose was to decrease the costs associated with this procedure. Methods: Twenty patients who underwent ACL reconstruction were selected. A tibial tunnel was constructed using standard techniques, and a femoral tunnel was anatomically created using the outside-in technique. The hamstring autograft was passed (with its bend) into the tibial tunnel and affixed to the tibia using the suspensory technique and a simple staple. Femoral fixation was performed using a titanium interference screw. The patients underwent postoperative evaluations at 0, 3, 6 and 12 months using the subjective International Knee Documentation Committee (IKDC) form and Lysholm knee scores. Results: The IKDC and Lysholm score results improved over time (p&lt;0.001) without major complications. The cost of the procedure could be reduced by using lower-cost hardware (staples). Conclusion: The proposed technique for anatomic ACL reconstruction using inverted hamstring grafts with their bend in the tibial tunnel, suspension-type fixation using a staple demonstrated good to excellent results after 1 year of follow up, with lower aggregate costs. Level of Evidence IV; Case series.
