1. Brazilian dentists' perception of dentin hypersensitivity management
Abstract: The aim of this study was to investigate how Brazilian dentists perceive and manage dentin hypersensitivity (DH) in their clinical routine. A 13-item questionnaire-based survey was developed and sent electronically to a convenience sample of dentists. The questionnaire assessed the personal and dental practice characteristics of the sample, the occ

2. Effects of Syzygium aromaticum, Cinnamomum zeylanicum, and Salvia triloba extracts on proliferation and differentiation of dental pulp stem cells
Abstract Hypersensitivity, local irritative and cytotoxic effects are known for the chemical components of Syzygium aromaticum and Cinnamomum zeylanicum contained in dental materials. However, there is no intimate data in dentistry using the whole extracts of these plants and introducing new ones. Salvia triloba is a well-known anti-inflammatory plant that c

3. Gestation and breastfeeding in schistosomotic mothers differently modulate the immune response of adult offspring to postnatal Schistosoma mansoni infection
Schistosoma mansoni antigens in the early life alter homologous and heterologous immunity during postnatal infections. We evaluate the immunity to parasite antigens and ovalbumin (OA) in adult mice born/suckled by schistosomotic mothers. Newborns were divided into: born (BIM), suckled (SIM) or born/suckled (BSIM) in schistosomotic mothers, and animals from n

4. Immunological response to re-infections with clones of the Colombian strain of Trypanosoma cruzi with different degrees of virulence: influence on pathological features during chronic infection in mice
Re-infections with Trypanosoma cruzi are an aggravating factor for Chagas disease morbidity. The Colombian strain of T. cruzirepresents multiclonal populations formed by clonally propagating organisms with different tropisms and degrees of virulence. In the present study, the influence of successive inoculations with clones of the Colombian strain, exhibitin

5. Effect of lipoarabinomannan from Mycobacterium avium subsp avium in Freund’s incomplete adjuvant on the immune response of cattle
The aim of the present study was to determine whether lipoarabinomannan (LAM), in combination with Freund’s incomplete adjuvant (FIA), was able to improve cell-mediated and antibody-mediated immune responses against ovalbumin (OVA) in cattle. Twenty-three calves were assigned to four treatment groups, which were subcutaneously immunized with either OVA plu

6. An experimental protocol for the establishment of dogs with long-term cellular immune reactions to Leishmania antigens
Domestic dogs are considered to be the main reservoirs of zoonotic visceral leishmaniasis. In this work, we evaluated a protocol to induce Leishmania infantum/Leishmania chagasi-specific cellular and humoral immune responses in dogs, which consisted of two injections of Leishmania promastigote lysate followed by a subcutaneous inoculation of viable promastig

7. Effect of vitamin E levels on the cell-mediated immunity of broilers vaccinated against coccidiosis
Studies on the relationships between animal nutrition and immunity have sought reliable methodologies to measure responses. Cell-mediated immune response is similarly studied in humans. The cutaneous basophil hypersensitivity test (CBH) is one of the methods to measure that response and consists in the infiltration of inflammatory cells, particularly of lymp

8. Bioactivity guided isolation and characterization of the phytoconstituents from the Tridax procumbens
Tridax procumbens L., Asteraceae, has been extensively used in Ayurvedic system of medicine for various ailments. Previous studies on the extracts of T. procumbens revealed remarkable immunomodulatory activity of TPEIF (T. procumbens ethanol insoluble fraction) extract. The dried methanol extract of T. procumbens was dissolved in distilled water, and then fr

9. In silico identification of coffee genome expressed sequences potentially associated with resistance to diseases.
Sequences potentially associated with coffee resistance to diseases were identified by in silico analyses using the database of the Brazilian Coffee Genome Project (BCGP). Keywords corresponding to plant resistance mechanisms to pathogens identified in the literature were used as baits for data mining. Expressed sequence tags (ESTs) related to each of these

11. Obtenção e caracterização de frações purificadas de saponinas de chenopodium quinoa e avaliação da formação de complexos do tipo iscom : atividades biológicas das frações e dos complexos formados
Chenopodium quinoa (quinoa) seeds are a rich protein source and well-known for their high saponin content. Chemically, quinoa saponins are triterpene glycosides being phytolaccagenic, hederagenin, oleanolic and serjanic acids the most common aglycones found in seeds. Its immunoadjuvant properties have been examined and the results obtained were conflicting.
