Venomics Profiling of Thamnodynastes strigatus Unveils Matrix Metalloproteinases and Other Novel Proteins Recruited to the Toxin Arsenal of Rear-Fanged Snakes

Rear-fanged and aglyphous snakes are usually considered not dangerous to humans because of their limited capacity of injecting venom. Therefore, only a few studies have been dedicated to characterizing the venom of the largest parcel of snake fauna. Here, we investigated the venom proteome of the rear-fanged snake Thamnodynastes strigatus, in combination with a transcriptomic evaluation of the venom gland. About 60% of all transcripts code for putative venom components. A striking finding is that the most abundant type of transcript (similar to 47%) and also the major protein type in the venom correspond to a new kind of matrix metalloproteinase (MMP) that is unrelated to the classical snake venom metalloproteinases found in all snake families. These enzymes were recently suggested as possible venom components, and we show here that they are proteolytically active and probably recruited to venom from a MMP-9 ancestor. Other unusual proteins were suggested to be venom components: a protein related to lactadherin and an EGF repeat-containing transcript. Despite these unusual molecules, seven toxin classes commonly found in typical venomous snakes are also present in the venom. These results support the evidence that the arsenals of these snakes are very diverse and harbor new types of biologically important molecules.Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPq)Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPq)Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP)Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP)Fundacao de Amparo a Pesquisa do Estado de Rio de Janeiro (FAPERJ)Fundacao de Amparo a Pesquisa do Estado do Rio de Janeiro (FAPERJ)Fundacao Oswaldo Cruz/PDTISFundacao Oswaldo Cruz/PDTISInstituto Nacional de Ciencia e Tecnologia em Toxinologia (INCTTox)Instituto Nacional de Ciencia e Tecnologia em Toxinologia (INCTTox

Effectiveness of imaging-guided intra-articular injection: a comparison study between fluoroscopy and ultrasound

OBJECTIVE: Compare the effectiveness of ultrasound and fluoroscopy to guide intra-articular injections (IAI) in selected cases. MATERIAL AND METHODS: A prospective study in our outpatient clinics at the Rheumatology Division at Universidade Federal de São Paulo (UNIFESP), Brazil, was conducted to compare the short-term (4 weeks) effectiveness of ultrasound and fluoroscopy-guided IAI in patients with rheumatic diseases. Inclusion criteria were: adults with refractory synovitis undergoing IAI with glucocorticoid. All patients had IAI performed with triamcinolone hexacetonide (20mg/ml) with varying doses according to the joint injected. RESULTS: A total of 71 rheumatic patients were evaluated (52 women, 44 whites). Mean age was 51.9 ± 13 years and 47 of them (66.2%) were on regular DMARD use. Analysis of the whole sample (71 patients) and hip sub-analysis (23 patients) showed that significant improvement was observed for both groups in terms of pain (P < 0.001). Global analysis also demonstrated better outcomes for patients in the FCG in terms of joint flexion (P < 0.001) and percentage change in joint flexion as compared to the USG. Likert scale score analyses demonstrated better results for the patients in the USG as compared to the FCG at the end of the study (P < 0.05). No statistically significant difference between groups was observed for any other study variable. DISCUSSION AND CONCLUSION: Imaging-guided IAI improves regional pain in patients with various types of synovitis in the short term. For the vast majority of variables, no significant difference in terms of effectiveness was observed between fluoroscopy and ultrasoundguided IAI.OBJETIVOS: Comparar a curto prazo (04 semanas) a efetividade das infiltrações intra-articulares (IIA) guiadas por fluoroscopia (FC) e ultrassom (US) em pacientes com enfermidades reumáticas. MATERIAL E MÉTODOS: Foi realizado um estudo controlado e prospectivo em pacientes portadores de doenças reumáticas captados dos ambulatórios da Disciplina de Reumatologia da Universidade Federal de São Paulo (UNIFESP), Brasil. Critério de inclusão: adultos com indicação de IIA com corticosteróide por sinovite refratária. Todos os pacientes forma infiltrados com hexacetonide triancinolona (20 mg/mL) com doses variáveis, de acordo com a articulação estudada. RESULTADOS: Foram avaliados 71 pacientes (52 mulheres; 44 brancos), portadores de enfermidades reumáticas variadas. A média de idade era 51,9 ± 13 anos e 47 deles (66,2%) faziam uso de drogas modificadora do curso da doença (DMARD). Na análise global da amostra (71 pacientes) e na subanálise coxofemoral (23 pacientes), observou-se melhora estatística (p < 0,001) em ambos os grupos quanto à EVA de dor. Na análise global observou-se aumento significativo da flexão articular (p < 0,001) e um Δ de flexão maior a favor do grupo guiado por FC. A avaliação de melhora segundo Likert Scale mostrou diferença significativa (p < 0,05) entre os grupos na avaliação global, nas proporções inalterado e melhor, a favor do grupo guiado por US. Não foi observada diferença estatisticamente significante entre os grupos para qualquer outra variável. CONCLUSÃO: A IIA guiada por imagem melhorou a dor regional, a curto prazo, relacionada à sinovite de vários tipos de articulações. Para a grande maioria das variáveis avaliadas não houve diferença entre a efetividade da IIA guiada por US ou FC

Evaluation of ent-Kaurenoic Acid Derivatives for their Anticariogenic Activity

Ent-kaur-16(17)-en-19-oic acid (kaurenoic acid, KA) is a tetracyclic diterpene prototype for natural anticaries agents. Six KA derivatives were prepared and their antimicrobial activity against the main microorganisms involved in the caries process evaluated. The sodium salt of KA (KA-Na) was the most active, displaying very promising MIC values for most pathogens. Time-kill assays against the primary causative agent of caries (Streptococcus mutans) indicated that KA and KA-Na only inhibited growth in the first 12 h, suggesting a bacteriostatic effect. After this period (12-24 h), their bactericidal effect was clearly noted. KA and KA-Na showed no synergy when combined with the gold standard anticariogenic (chlorhexidine dihydrochloride, CHD) in the checkerboard assays against S. mutans.Fundacao de Amparo a Pesquisa de Sao Paulo (FAPESP)[2009/05550-3
