Abstract
Bifidobacterium infantis NLS super strain (B. infantis NLS-SS) was previously shown to alleviate gastrointestinal symptoms in newly diagnosed coeliac disease (CD) patients consuming gluten. A high proportion of patients following a gluten-free diet experiences symptoms despite dietary compliance. The role of B. infantis in persistently symptomatic CD patients has not been explored. The aim of the study was to evaluate the effect of B. infantis NLS-SS on persistent gastrointestinal symptoms in patients with CD following a long-term GFD. We conducted a randomised, cross-over, double-blind, placebo-controlled trial in symptomatic adult CD patients on a GFD for at least two years. After one-week run-in, patients were randomised to B. infantis NLS-SS or placebo for 3 weeks with cross-over after a 2-week wash-out period. We estimated changes (Δ) in celiac symptom index (CSI) before and after treatment. Stool samples were collected for faecal microbiota analysis (16S rRNA sequencing). Gluten immunogenic peptide (GIP) excretion in stool and urine samples was measured at each study period. Eighteen patients were enrolled; six patients were excluded due violations in protocol. For patients with the highest clinical burden, CD symptoms were lower in probiotic than in placebo treatment (P=0.046). B. infantis and placebo treated groups had different microbiota profiles as assessed by beta diversity clustering. In probiotic treated groups, we observed an increase in abundance of B. infantis. Treatment with B. infantis was associated with decreased abundance of Ruminococcus sp. and Bifidobacterium adolescentis. GIP excretion in stools and urine was similar at each treatment period. There were no differences in adverse effects between the two groups. B. infantis NLS-SS improves specific CD symptoms in a subset of highly symptomatic treated patients (GFD). This is associated with a shift in stool microbiota profile. Larger studies are needed to confirm these findings. ClinicalTrials.gov: NCT03271138.

Abstract
O objetivo da pesquisa foi comparar o efeito da Epigalocatequina-3-galato (EGCG), na forma pura e microencapsulada, incorporado ao sistema adesivo convencional e aplicado como pré-tratamento dentinário, na resistência de união à dentina. Primeiramente, realizou-se o grau de conversão (%GC) pelo Espectrofotômetro FT-IR e ensaio de liberação dos adesivos para avaliar o desempenho das micropartículas poliméricas carregadas com EGCG. Em seguida, 45 terceiros molares humanos foram divididos em 5 grupos (n9) de acordo com a solução de pré-tratamento e sistema adesivo utilizado e foram submetidos ao teste de microtração em uma máquina de ensaios universais. Não houve diferença estatística significante entre as médias do grau de conversão. (p>0,05). Em relação ao ensaio de liberação, o grupo PLGA50:50/EGCG a 1,0% apresentou melhores resultados, alcançando a maior liberação em termos quantitativos. Nenhuma diferença estatisticamente significante foi encontrada entre as médias dos valores de resistência de união (p>0,05). A incorporação das micropartículas poliméricas carregadas com EGCG não interferiu no grau de conversão dos adesivos. O sistema adesivo com micropartículas carregadas com EGCG incorporado em sua composição foi capaz de liberar EGCG. Porém, o EGCG não teve efeito estatisticamente significante quando incorporado ao sistema adesivo convencional ou aplicado como pré-tratamento da dentina, de forma pura e microencapsulada, na resistência de união imediata porém, pode aumentar a durabilidade da interface de união ao longo do tempo.Palavras-chave: Adesivos. Polímeros. Catequina. Metaloproteinases da Matriz.

Abstract
Nesse contexto, o objetivo dessa revisão de literatura foi investigar agentes naturais por apresentarem baixa toxicidade além de serem recursos sustentáveis, viáveis para uso odontológico, que se apresentam como potenciais agentes biomodificadores. Para isso, foram selecionados artigos publicados entre os anos 2000 e 2017 na língua inglesa, usando as base de dados PubMed, Bireme e Scielo com. Foi possível constatar na literatura que agentes como as proantocianidinas (PACs), epigalocatequina-3-galato (EGCG) entre outras catequinas, resveratrol, cardol, cardanol, PA oligoméricas, genipina, hesperidina e outros polifenóis são benéficos na inativação de metaloproteinases de matriz (MMPs) e na biomodificação do colágeno podendo ser aplicados clinicamente como pré- tratamento dentinário ou incorporados ao adesivo.Palavras-chave: Crosslink.

Abstract
O objetivo desta revisão de literatura foi investigar os critérios de classificação de lesões cariosas associados ao diagnóstico precoce e à técnica minimamente invasiva. Para isso, foram selecionados artigos publicados no período de 2000 a 2017, na língua inglesa, com base de dados em PUBMED e utilizando os seguintes descritores: Dental Caries, DMF index, Health services epidemiology. Dos 27 artigos encontrados foram selecionados 17 artigos que se adequavam à pesquisa. O diagnóstico precoce e correto das lesões cariosas são a chave do sucesso de tratamentos minimamente invasivos na Odontologia, apesar de que, antes de qualquer tratamento preventivo ou restaurador, há a necessidade de calibração sobre a avaliação das lesões dentárias em questão.Palavras-chave: Dental Caries.

Abstract
The vanilloid receptor represents a promising target for drug development. Building on our previous strategies which have generated potent agonists for VR1, we now describe a series of novel N-(3-acyloxy-2-benzylpropyl)-N'-dihydroxytetrahydrobenzazepine and tetrahydroisoquinoline thiourea analogues, several of which are potent VR1 antagonists. We report here the rationale for the design, the synthesis, and the in vitro characterization of activity in assays for [(3)H]resiniferatoxin binding and (45)Ca influx using heterologously expressed rat VR1.

Abstract
OBJECTIVE To characterize the initial manifestations and course of muscle infarction in diabetes, a rarely diagnosed condition. METHODS We describe two patients with this disorder and review the clinical characteristics of previously reported cases. RESULTS Usually, the initial complaint in patients with muscle infarction in diabetes is swelling of the thigh or calf that has evolved over days to months. Biopsy of the muscle is often necessary for diagnosis and reveals extensive muscle necrosis. Although the pathogenesis is unknown, hypercoagulability may have a role. Bilateral involvement and recurrent disease are common. Treatment is supportive; our patients required narcotics for alleviation of pain. CONCLUSION Muscle infarction in diabetes may mimic thrombophlebitis, soft tissue infection, or a neoplasm. Medical evaluation may be directed toward these entities, and the diagnosis of a diabetes-associated disorder may be completely overlooked. The presence of atraumatic swelling of an extremity in a patient with diabetes should suggest diabetes-related muscle infarction.
