Abstract:
ABSTRACT Strains of Streptococcus mutans lacking DnaK or GroEL appear not to be isolable. To better distinguish the roles played by these chaperones/chaperonins in the physiology of S. mutans, we created a knockdown strategy to lower the levels of DnaK by over 95% in strain SM12 and the level of GroEL about 80% in strain SM13. Interestingly, GroEL levels were approximately twofold higher in SM12 than in the parent strain, but the levels of DnaK were not altered in the GroEL knockdown strain. Both SM12 and SM13 grew slower than the parent strain, had a strong tendency to aggregate in broth culture, and showed major changes in their proteomes. Compared with the wild-type strain, SM12 and SM13 had impaired biofilm-forming capacities when grown in the presence of glucose. The SM12 strain was impaired in its capacity to grow at 44°C or at pH 5.0 and was more susceptible to H2O2, whereas SM13 behaved like the wild-type strain under these conditions. Phenotypical reversions were noted for both mutants when cells were grown in continuous culture at a low pH, suggesting the occurrence of compensatory mutations. These results demonstrate that DnaK and GroEL differentially affect the expression of key virulence traits, including biofilm formation and acid tolerance, and support that these chaperones have evolved to accommodate unique roles in the context of this organism and its niche.

Abstract:
Marine actinomycetes are being explored to discover potential actinomycetes that produce antifungal compounds. In a previous study, marine actinomycetes isolates from the mangrove ecosystem were found to inhibit growth of the phytopathogenic fungi Colletotrichum siamense KA. In this study, the three of these isolates with the highest antagonistic activity—SM11, SM14, and SM15—were evaluated for their antifungal activity using antibiosis assay. The fermentation was performed in SCB:PDB medium (1:1) for 6, 9, and 12 days. The results showed that SM14 was the strongest potential isolate; it inhibited the growth of C. siamense KA on average up to 64.90% for 12 days on PDA filtrate medium. Molecular identification showed SM14 was closely related to Streptomyces sanyensis, but had differences in morphological and biochemical characteristics compared to SM11 or SM15. This indicated that the three isolates were different strains and may challenge further research on identifying and analyzing their antifungal compounds.

Abstract:
This paper reports the first direct molecular evidence that X chromosome loss during determination of male aphids (XO) is random. Clonal and sexual females, and males, of the species Sitobion near fragariae were screened using three polymorphic microsatellite loci. Two loci, Sm10 and Sm17, showed the same heterozygous genotypes in all three aphid morphs. The third, Sm11, was heterozygous for the same two alleles in clonal and sexual females, but of the 25 males screened 11 showed the ‘160’ allele and 14 showed the ‘156’ allele. This result indicates X-linkage of locus Sm11, with random loss of the X chromosome during the formation of male embryos. The possible implications of this result are discussed with respect to aphid sex determination, recombination and chromosome evolution.

Abstract:
Smooth muscle myosin heavy chain (SMHC) isoforms, SM1 and SM2, are the products of alternative splicing from a single gene (P. Babij and M. Periasamy. J. Mol. Biol. 210: 673-679, 1989). We have previously shown that this splicing occurs at the 3'-end of the mRNA, resulting in proteins that differ at the carboxyterminal (R. Nagai, M. Kuro-o, P. Babij, and M. Periasamy. J. Biol. Chem. 264: 9734-9737, 1989). In the present study we demonstrate that additional SMHC isoform diversity occurs in the globular head region by isolating and characterizing two distinct rat SMHC cDNA (SMHC-11 = SM1B and SMHC-5 = SM1A). Sequence comparison of the two clones reveals that they are completely identical in their coding regions, except at the region encoding the 25/50 kDa junction of the myosin head, where the SM1B isoform contains an additional seven amino acids. This divergent region is located adjacent to the Mg(2+)-ATPase site, and differences in this region may be of functional importance. Ribonuclease protection analysis demonstrates that the corresponding SM1B and SM1A mRNA messages are coexpressed in all smooth muscle tissues; however, the proportion of the two mRNA present differs significantly between tissues. The SM1A-type mRNA predominates in most smooth muscle tissues, with the exception of intestine and urinary bladder, which contain greater proportions of the SM1B message. The differential distribution of these two isoforms may provide important clues toward understanding differences in smooth muscle contractile properties.

Abstract:
Two Schistosoma mansoni cDNA clones 30S and 1H were identified by immunoscreening of sporocyst lambdagt11 library and by random sequencing of clones from lambdaZap libraries, respectively. Clone 30S was one of 30 clones identified by an antibody raised against tegument of 3-h schistosomules. The clone was found to encode an 81 amino-acid protein fragment. It was expressed in Escherichia coli as a fusion protein of calculated molecular mass of about 35 kDa with C-terminus of Schistosoma japonicum glutathione-S-transferase (Sj26; about 26 kDa). The recombinant fusion protein was specifically recognized by serum of rabbits immunized with irradiated cercariae. Clone 1H is one of 76 expressed sequence tags derived from an adult worm library. It encodes the complete sequence of a tegumental membrane protein, Sm13. The 104 amino-acid open reading frame encodes a protein with a calculated molecular mass of about 11.9 kDa. Clone 1H was expressed in E. coli as an insoluble fusion protein with Sj26 of about 40 kDa. In Western blots, the fusion protein was recognized by serum from rabbits vaccinated with irradiated cercariae but not by preimmune rabbit sera. The cloning, characterization and expression of those proteins are therefore potentially usefull for vaccine development.

p53 is a transcription factor with tumour suppressor properties, which is able to induce mitochondrial apoptosis independently of its transcriptional activity. Analogues of the spiro[imidazo[1,5-c] thiazole-3,3′-indoline] -2′,5,7(6H,7aH) -trione, previously synthesized from my research group, as p53 modulators were synthesized during my PhD, aiming to explore new structural requirements at the thiazolidine domain to increase the antiproliferative activity and improve p53 modulation.

Abstract:
As proteínas ligadoras de ácidos graxos (Fatty Acid Binding Proteins, FABPs) de parasitos têm um papel importante no processo de infecção por estes organismos. Por este motivo, estas proteínas são antígenos candidatos para vacina contra a infecção por Schistosoma mansoni e Fasciola hepatica. No presente trabalho foram caracterizadas FABPs de F. hepatica e comparadas com a proteína Sm14 de S. mansoni, a FABP de parasito melhor caracterizada, mediante análise de sequências e estruturas modeladas. Também foram clonadas, expressas e purificadas as FABPs tipo 1 e tipo 3 de F. hepatica. Os resultados do presente estudo indicam que a FABP tipo 3 de F. hepatica é relacionada estrutural, imunológica e funcionalmente com a Sm14, um candidato vacinal amplamente estudado. Devido à importância da Sm14 como alvo para o desenvolvimento de vacina para a esquistossomose, as características apresentadas pela FhFABP3 de F. hepatica apontam esta proteína como um candidato importante também para o desenvolvimento de uma vacina contra a fasciolose
Parasites fatty acid binding proteins (FABPs) have an important role in infection process by these organisms. For this reason, these proteins are candidates as vaccine antigens against Schistosoma mansoni and Fasciola hepatica infection. In the present study, FABPs from F. hepatica were characterized and compared with Sm14 protein from S. mansoni, the best characterized parasite FABP, by sequence analysis and modeled structure. Type 1 and type 3 FABPs from F. hepatica were also cloned, expressed and purified. The results of this study indicated that type 3 FABP from F. hepatica is structural, immunological and functionally related with Sm14, a vaccine candidate widely studied. Due to the importance of Sm14 as a target for vaccine development for schistosomiasis, the characteristics presented by the FhFABP3 from F. hepatica suggest this protein as a candidate also important for the development of a vaccine against fasciolosis

Abstract:
SMC1 and SMC3 form a high-affinity heterodimer, which provides an open backbone of the cohesin ring, to be closed by a kleisin protein. RNAi mediated knock-down of either one heterodimer partner, SMC1 or SMC3, is expected to cause very similar if not identical phenotypes. However, we observed highly distinct, protein-specific phenotypes. Upon knock-down of human SMC1, much of SMC3 remains stable, accumulates in the cytoplasm and does not associate with other cohesin proteins. Most of the excess nuclear SMC3 is highly mobile and not or only weakly chromosome-associated. In contrast, human SMC3 knock-down rendered SMC1 instable without cytoplasmic accumulation. As observed by differential protein extraction and in FRAP experiments the remaining SMC1 or SMC3 proteins in the respective SMC1 or SMC3 knock-down experiments constituted a cohesin pool, which is associated with chromatin with highest affinity, likely the least expendable. Expression of bovine EGFP-SMC1 or mouse EGFP-SMC3 in human cells under conditions of human SMC1 or SMC3 knock-down rescued the respective phenotypes, but in untreated cells over-expressed exogenous SMC proteins mis-localized. Paucity of either one of the SMC proteins causes RAD21 degradation. These results argue for great caution in interpreting SMC1 and SMC3 RNAi or over-expression experiments. Under challenged conditions these two proteins unexpectedly behave differently, which may have biological consequences for regulation of cohesin-associated functions and for human cohesin pathologies.

Abstract:
Modeling systems in liquid is imperative to chemistry, as many reactions take place in liquid, and nearly all of biochemistry is in the liquid state. Solvation Model 12 (SM12) is the newest Generalized Born Approximation iteration of a series of solvation models from Minnesota, it shows great promise for accurate, description of solutions. Shown is the full implementation of SM12 in to the pure Slater Type Orbital code, the Amsterdam Density Functional (ADF) package in particular. The model performs as well as its Gaussian Type Orbital counterpart. The model has been extended to account for periodic boundary conditions, as presented by the ADF-BAND code. The extension to infinite boundaries creates interesting edge effects that need to be taken into consideration, and are accounted for through cut off approximations and a screening function to ensure the potential is well-behaved.

Abstract:
A esquistossomose é uma das mais relevantes doenças induzidas por helmintos, acometendo cerca de 207 milhões de pessoas em todo o mundo. O Praziquantel e o Oxamniquine são os fármacos empregados no tratamento, mas além de não impedirem re-infecções, não atuam nos estágios imaturos do verme. Portanto, o desenvolvimento de uma estratégia de vacinação eficaz representa um componente essencial para o controle e erradicação desta doença. Neste sentido, tivemos como objetivo estudar a resposta imunológica induzida pela imunização com a vacina DNA-Sm14 em associação com a DNA-Hsp65 utilizando protocolos de imunização prime-boost, sendo eles heterólogo ou homólogo. A utilização das vacinas em prime-boost heterólogo não alterou a produção de IgG2a, mas diminuiu a produção de IFN- e IL-10 dos animais quando comparados aos que receberam apenas DNA-Sm14. Após infecção, a estratégia prime-boost heterólogo não foi eficaz em reduzir a carga parasitária dos animais, enquanto a vacinação com DNA-Sm14 reduziu parcialmente o número de vermes. Na vacinação prime-boost homóloga utilizando as duas vacinas, observamos que a modificação da estratégia também não alterou a produção de IgG2a, mas reduziu a produção de IFN- pelas células recuperadas do espaço bronco-alveolar, quando comparada com os animais que receberam DNA-Sm14. Após infecção, a imunização com DNA-Sm14/DNA-Hsp65 não alterou a carga parasitária dos animais, mas sistemicamente reduziu o número de eosinófilos. Quando avaliado o perfil de células de memória dos animais vacinados, verificamos aumento do número de células T CD8+ e menor número de células T CD4+ no baço dos animais imunizados com as duas vacinas simultaneamente. Em suma, a utilização das vacinas DNA-Sm14 e DNA-Hsp65 nas estratégias prime-boost heterólogo ou homólogo não foi capaz de gerar proteção contra infecção experimental por S. mansoni, e sugerimos que em parte, a diminuição de IFN-, IL-10, aumento da razão IgG1/IgG2a e a estimulação de células T CD8+ ao invés de CD4+, podem ter contribuído para baixa eficácia dos protocolos vacinais testados.
Schistosomiasis is one of the most important diseases due to helminthes, affecting approximately 207 million people worldwide. The treatment is based on Praziquantel and Oxamniquine drugs, however these drugs do not avoid reinfections and are inefficient against worm immature stages. Therefore, the development of an efficient vaccination strategy is an essential component in the control of this disease. The aim of this work was to study the immune response induced by immunization with DNA-Sm14 vaccine in combination with DNA-Hsp65 using prime-boost protocols, which were heterologous or homologous. The heterologous prime-boost vaccination did not modify IgG2a production, but decreased IFN- and IL-10 production compared to animals that received only DNA-Sm14. After infection, this prime-boost strategy was not effective in reducing the worm burden of animals, while vaccination with DNA-Sm14 induced partial reduction. Using both vaccines in the homologous prime-boost model, we found that the modification of the strategy did not alter IgG2a production, although reduced IFN- production by cells recovered from the broncho-alveolar space compared to DNA-Sm14 immunized mice. After infection, immunization with DNA-Sm14/DNA-Hsp65 didnt modify the animals parasitic burden, however systemically, reduced eosinophils number. When the profile of memory cells in vaccinated animals was evaluated, we verified increased numbers of CD8+ T cells and lower numbers of CD4+ T cells in the spleen of animals immunized with both vaccines simultaneously. In conclusion, the vaccines DNA-Sm14 and DNA-Hsp65 in both strategies, prime-boost heterologous or homologous, were not able to generate protection against experimental infection with S. mansoni, and we propose that, partly, the decrease of IFN-, IL-10 levels, increase of IgG1/IgG2a ratio and the stimulation of CD8+ T cells rather than CD4+, may have contributed to the low efficacy of the vaccination protocols tested.

The Sm2O3-doped calcium borotellurite glasses studied in this research were synthesized by melt-quenching method, characterized according to their structural, thermal, spectroscopic and optical properties and analyzed as a function of TeO2 concentration. The analysis of the properties was performed by the following characterizations: X-ray diffraction, volumetric density, Raman spectroscopy, Fourier transform infrared spectroscopy (FTIR), optical absorption spectroscopy, differential thermal analysis (DTA), specific heat, refractive index, photoluminescence and lifetime decay. In addition, molar volume, optical band gap, electronic polarizability, number of ions per cubic centimeter, interionic distance, chromaticity, DE/DM ratio and orange/red ratio values were also evaluated. The results have showed that the increase of TeO2 concentration increased the volumetric density (~41%). The X-Ray spectra confirmed the amorphous nature of the samples. The Raman and FTIR results indicated the presence of the following structures: TeO3, TeO3+1, TeO4, BO3 and BO4. Moreover, the increase of nonbridging oxygen was confirmed. The increase of the TeO2 concentration decreased the specific heat and the glass transition temperature of the samples. The refractive index increased, due to an increase of density and electronic polarizability. The insertion of the doping agent was confirmed by the optical absorption spectra, which presented peaks characteristic of Sm3+ ions (most intense peak at ~402 nm). The emission intensity of the Sm3+ ions decreased (~2.2%) with the increase of TeO2 concentration. The chromaticity of the samples analyzed by CIE diagram showed small variation at x and y positions. However, under visual inspection, the variation of the emitted color was not observed. The emission intensity as a function of temperature, showed a decrease for all samples. The lifetime for the emission at ~598 nm also presented a reduction with the increase of TeO2 content, due to the increase of NBOs. Therefore, the synthesized materials present good properties, and finds their applications as potential candidate for optical devices, such as solid state lasers, Light-emitting diodes (LEDs), among others.
Os vidros cálcio boroteluretos dopados com Sm2O3 estudados neste trabalho foram sintetizados pelo método de fusão/resfriamento e caracterizados quanto às suas propriedades estruturais, térmicas, espectroscópicas e ópticas. Essas propriedades foram analisadas em função da concentração de TeO2. A análise das propriedades foi feita por meio das seguintes caracterizações: densidade volumétrica (método de Arquimedes), difração de raios-X, espectroscopia Raman, espectroscopia no infravermelho via transformada de Fourier (FTIR), espectroscopia de absorção óptica, análise térmica diferencial (DTA), calor específico, índice de refração, fotoluminescência e tempo de vida, além do cálculo dos valores de energia de band gap óptico, polarizabilidade eletrônica, número de íons por centímetro cúbico, distância interiônica, cromaticidade, razão dipolo elétrico/dipolo magnético (DE/DM) e razão laranja/vermelho. A densidade e o volume molar tiveram um aumento simultâneo devido ao aumento da massa molar do vidro. Os espectros de difratometria de raios-X mostraram que todas as amostras são amorfas e sem a presença de cristalitos. A temperatura de transição vítrea e o calor específico das amostras diminuíram com o aumento da concentração de TeO2. Os resultados de Raman e FTIR mostraram a presença das estruturas TeO3, TeO3+1, TeO4, BO3 e BO4.O índice de refração também teve um aumento, devido ao aumento da densidade e da polarizabilidade eletrônica. Por meio dos espectros de absorção óptica foi comprovada a inserção do dopante nas amostras, pois apresentam picos de absorção característicos do Sm3+, sendo o pico mais intenso em ~402 nm. A intensidade de emissão teve uma redução (~2,2%) com o aumento de TeO2. O tempo de vida para a emissão em ~598 nm também teve uma redução com o aumento da concentração de TeO2, devido ao aumento de oxigênios não-ligados (NBOs). A cromaticidade das amostras analisadas pelo diagrama CIE, mostrou uma pequena variação nas posições x e y, no entanto, sob inspeção visual não houve variação da cor emitida. Os resultados mostraram que o material sintetizado apresenta boas propriedades, com potencial para ser aplicado em dispositivos fotônicos, como lasers de estado sólido, lasers emissores de luz (LEDs), dentre outros.

Abstract:
Background. China is regulating the import, export, sale, and use of encryption technology in China. If any foreign company wants to develop or release a product in China, they need to report their use of any encryption technology to the Office of State Commercial Cryptography Administration (OSCCA) to gain approval. SM2, SM3, and SM4 are cryptographic standards published by OSCCA and are authorized to be used in China. To comply with Chinese cryptography laws organizations and companies may have to replace standard cryptographic algorithms in their systems with Chinese cryptographic algorithms, such as SM2, SM3, and SM4. It is important to know beforehand how the replacement of algorithms will impact performance to determine future system costs. Objectives. Perform a theoretical study and performance comparison of the standard cryptographic algorithms and Chinese Cryptographic algorithms. The standard cryptographic algorithms studied are RSA, ECDSA, SHA-256, and AES-128, and the Chinese cryptographic algorithms studied are SM2, SM3, and SM4. Methods. A literature analysis was conducted to gain knowledge and collect information about the selected cryptographic algorithms in order to make a theoretical comparison of the algorithms. An experiment was conducted to get measurements of how the algorithms perform and to be able to rate them. Results. The literature analysis provides a comparison that identifies design similarities and differences between the algorithms. The controlled experiment provides measurements of the metrics of the algorithms mentioned in objectives. Conclusions. The conclusions are that the digital signature algorithms SM2 and ECDSA have similar design and also similar performance. SM2 and RSA have fundamentally different designs, and SM2 performs better than RSA when generating keys and signatures. When verifying signatures, RSA shows comparable performance in some cases and worse performance in other cases. Hash algorithms SM3 and SHA-256 have many design similarities, but SHA-256 performs slightly better than SM3. AES-128 and SM4 have many similarities but also a few differences. In the controlled experiment, AES-128 outperforms SM4 with a significant margin.
Bakgrund. Kina reglerar import, export, försäljning och användning av krypteringsteknologi i Kina. Om ett utländskt företag vill utveckla eller släppa en produkt i Kina måste de rapportera sin användning av krypteringsteknologi till Office of State Commercial Cryptography Administration (OSCCA) för godkännande. SM2, SM3 och SM4 är kryptografiska standarder som lagligt får används i Kina. Organisationer och företag kan behöva byta ut krypteringsalgoritmerna i sina system till kinesiska krypteringsalgoritmer för att uppfylla kraven för de kinesiska lagarna. Det är därför viktigt att i förväg veta hur ersättningen av algoritmer kommer att påverka prestandan för att utvärdera framtida kostnader för systemet. Syfte. Genomföra en teoretisk studie och prestanda jämförelse av standard krypteringsalgoritmer och kinesiska krypteringsalgoritmer. De standard krypteringsalgoritmerna är RSA, ECDSA, SHA-256 och AES-128. De kinesiska krypteringsalgoritmerna är SM2, SM3 och SM4. Metod. En litteraturanalys har genomförts för att få en bättre förståelse av de valda algoritmerna. Ett experiment har genomförts för att samla mätvärden av de bestämda parametrarna och för att sedan kunna ranka mätvärdena. Resultat. Litteraturanalysen gav en jämförelse som identifierar likheter och skillnader mellan algoritmerna. Det kontrollerade experimentet gav mätvärden av parametrarna för algoritmerna nämnda i syftet. Slutsatser. Slutsatserna är att de digitala signatur-algoritmerna SM2 och ECDSA har liknade design och också liknade prestanda. SM2 och RSA har fundamentala skillnader i deras design, och SM2 har bättre prestanda vid nyckelgenerering samt signaturgenerering. Vid verifiering av signaturer så visar RSA likvärdig prestanda i vissa fall och sämre prestanda i andra fall. Hashfunktionerna SM3 och SHA-256 har också många likheter i sin design, men SHA-256 presterar lite bättre än SM3. AES-128 och SM3 har många design likheter men också några skillnader. I det kontrollerade experimentet så presterar AES-128 bättre än SM4 med stor marginal.

Abstract:
Abstract This paper reports the results of high-pressure combustion rig testing carried out to assess the fuel flexibility of the standard Siemens Energy SGT-300-2S dry low emission (DLE) combustion system operated at engine conditions across a wide range of engine loads and ambient conditions. Variations of the fuel heating value, with Wobbe Index (WI) of 23 MJ/Sm3, 25 MJ/Sm3, 27.5 MJ/Sm3, 30 MJ/Sm3 and 45 MJ/Sm3 (UK natural gas) at standard conditions1, were achieved in a mixing plant by blending natural gas with CO2 as diluent. Emissions, fuel pressure, combustion dynamics, and flashback monitoring via measurement of burner and combustor can metal temperatures were the main parameters used to assess the effect of fuel flexibility on combustor performance. Test results show that NOx emissions decrease as the fuel heating value is reduced due to lower adiabatic flame temperatures for the MCV (Medium Calorific Value) fuels. CO emissions performance was found to be unaffected. However, decreasing fuel heating value leads to a requirement to increase the fuel supply pressure as a consequence of higher volumetric fuel flow rate to achieve the heat input requirements of the gas turbine. Combustion dynamics characteristics were found to be similar for the different fuel compositions. The impact of fuel heating value change on turbine nozzle guide vanes and blades was also investigated by measuring the combustion hot gas temperature profile at the exit of transition duct. The results show that there is no significant change in turbine entry temperature profile in terms of maximum temperature and pattern factors. The successful development program has expanded the capability of the SGT-300-2S standard production DLE combustor to operate with a range of fuels covering a WI range of 25 MJ/Sm3 to 49 MJ/Sm3. The test results obtained on the SGT-300-2S combustion system provide significant experience for industrial gas turbine burner design for fuel flexibility.
