Analysis of protein profile of tomato root infected with Fusarium oxysporum f. sp lycopersici.

Fusarium wilt caused by Fusarium oxysporum f. sp lycopersici (Fol) is one of the main diseases affecting tomatoes. The BHRS 2,3 genotype of tomato is, however, resistant to this disease. A proteomic approach was used to understand the defense mechanisms of this genotype using the tomato root, the first tissue that interacts with the fungus, as a target. Protein was extracted and separated by two-dimensional electrophoresis followed by staining with Coomassie brilliant blue. The proteins were identified by MALDI-TOF/TOF mass spectrometry. A total of 22 proteins were identified, 21 of which showed differential expression with 12 proteins being upregulated and nine being downregulated. Plants responded to the pathogen with increased expression of pathogenesis-related proteins. We noted the induction of proteins involved in hypersensitivity reaction and other defense mechanisms. The expression of proteins of primary metabolism related to energy production, however, decreased, as did the expression of two proteins related to defense against abiotic stress. These results demonstrate the presence of important mechanisms for defense against Fol in the tomato genotype BHRS 2,3.

Protein extraction method for the proteomic study of Zymomonas mobilis during production of ethanol and levans.

Zymomonas mobilis has aroused considerable interest owing to its rapid metabolism and efficiency in producing ethanol and by-products such as levans, sorbitol, and gluconic acid from simple sugars. We performed a proteomic analysis of Z. mobilis UFPEDA241 to provide a global profile of regulatory proteins. The choice of the methods of extraction and cell lysis are fundamental steps and of great importance for the detection and identification of intra- and extracellular proteins of a proteome. Strains were subjected to protein extraction methods using three different reagents: TRIzol, lysis buffer, and phenol. The optimum method was taken to be the one that produced the greatest quantity and quality of proteins in one dimension for further analysis in two dimensions during the production of ethanol and levans over 72 h. The results showed that the greatest amount of protein was obtained by the phenol method (1.44 ± 0.07 mg/mL), which was significantly different (P < 0.05) to the TRIzol (1.11 ± 0.01 mg/mL), and lysis buffer (0.93 ± 0.01 mg/mL) methods (both with P > 0.05). Fermentation at 20°C produced the highest level of levans, and using two-dimensional electrophoresis and mass spectrometry it was possible to identify 34 differentially expressed spots.

CYP2E1 RsaI and 96-bp insertion genetic polymorphisms associated with risk for colorectal cancer.

We investigated a possible association between alcoholism, cigarette smoking, obesity and CYP2E1 RsaI and 96-bp insertion genetic polymorphisms with risk for colorectal cancer (CRC). Patients with CRC (70 women and 61 men) were matched for gender and age to 206 healthy controls. The mean age of the two groups was 62 years. Meat intake, cigarette smoking and alcohol drinking were assessed using a specific frequency questionnaire. The body mass index was also calculated. DNA was extracted from peripheral blood; RsaI polymorphism genotypes were evaluated by PCR-RFLP and 96-bp insertion genetic polymorphisms were evaluated by specific primers. The distributions of CYP2E1 RsaI c1/c1, c1/c2 and c2/c2 genotypes were 90.2, 9.2 and 0.6%, respectively, in controls and 83.9, 13.7 and 2.4% in CRC cases. Allele c2 was associated with increased risk for CRC [odds ratio (OR) = 1.88, 95% confidence interval (95%CI) = 1.02-3.45]. The CYP2E1 RsaI c2/c2 genotype was associated with an increased risk for rectal cancer (OR = 3.23, 95%CI = 1.26-9.03). The 96-bp insertion was slightly more frequent in the CRC group (9.3 vs 11.4%, P = 0.19), especially in females (6.4 vs 11.5%, P = 0.34). Smoking, alcohol drinking or high intake of red meat and CYP2E1 polymorphisms were not associated with increased risk for CRC. The 96-bp insertion was marginally more frequent (P = 0.07) in undernourished CRC subjects. We concluded that the risk for CRC is higher among individuals with allele c2. The CYP2E1 RsaI c2/c2 genotype was associated with an increased risk for rectal cancer.

Intake, performance, and feeding behavior of Holstein and Holstein × Gyr heifers grazing intensively managed tropical grasses during the rainy season.

Holstein × Gyr and Holstein are the primary dairy breeds used in tropical systems, but when rearing under pasture, feed intake, behavior, and performance might differ between them. This study aimed to evaluate the voluntary intake, nutrient digestibility, performance, and ingestive behavior of Holstein and Holstein × Gyr (½ Holstein × ½ Gyr) heifers managed in a rotational system of Guinea grass (Panicum maximum Jacq. cv. Mombaça). The experiment was conducted during the summer season throughout four periods of 21 d. Two 8-heifers (four Holstein and four Holstein × Gyr) groups, averaging 258.6 ±â€¯24.79 kg and 157.1 ±â€¯24.99 kg BW, were used. Each group grazed a separate set of 16 paddocks, and all heifers received a concentrate supplement daily. Heifers were weighed at the beginning and end of the experiment. Fecal, forage and concentrate samples were evaluated for their DM, CP, crude fat, ash, NDF, and indigestible NDF. Feeding behavior was evaluated through 24 h of live observation for 48 h of each experimental period. Grazing, ruminating, resting, and intake of concentrate times were recorded, and rumination criteria, bout criteria, mealtime, meal frequency, and meal duration were calculated. There was no difference in total dry matter intake (DMI), but forage DMI of Holstein × Gyr was 11.70 % greater than the Holstein heifers. The Holstein × Gyr heifers had greater NDF intake and feed efficiency tended to show greater CP and NDF digestibilities, consequently, they had greater average daily gain (ADG). Holstein grazed less than Holstein × Gyr heifers in the afternoon. Ruminating time was 18.43 % lower for Holstein than Holstein × Gyr heifers, and rumination criteria (i.e. longest non-feeding interval within a rumination event) were greater for Holstein heifers. Holstein heifers presented more prolonged rumination bouts and resting time than Holstein × Gyr heifers. Holstein × Gyr can ingest and ruminate greater amounts of fibrous material, and Holstein heifers needed to spend more time ruminating the cud. Overall, even though the behavior was not markedly different between breeds, rearing young Holstein heifers in tropical pasture conditions is less suitable than Holstein-Gyr because of their lower ADG. Therefore, this management condition seems appropriate for Holstein × Gyr but inappropriate for Holstein dairy heifers.

Teratogenic Effect of Usnic Acid from Cladonia substellata Vainio during Organogenesis.

Studies about toxicological potential of usnic acid are limited. This way, the vast majority of data available in the literature are related only to biological activities. This is the first study that aimed to evaluate the oral toxicity of usnic acid during the period of organogenesis. Females rats were distributed in the control groups, treated I and II, at doses of 15 and 25 mg/kg, administered by gavage during the 6° to 15° days of pregnancy. After 20 days the fetuses were removed and analyzed. A reduction in weight gain during pregnancy, increased resorption, reduction in the number of viable fetuses, and their body weight were observed. Morphological changes in the litter were visualized as exposure of the eye and atrophy of the limbs at the dose of 25 mg/kg. Histological analysis of the liver of the fetus showed reduction in the number of megakaryocytes between experimental groups and increase in the number of hepatocytes in a dose of 25 mg/kg. The experimental model used in this study reveals teratogenic effect of usnic acid in the period of organogenesis. Since this achievement, the importance of evaluating the toxic effects of natural substances is imperative, in order to elucidate the care in their indication as drug.

Estimation of dissociation constants (pKa's) of oximes from proton chemical shifts in dimethyl sulfoxide solution.

In connection with structure-activity studies of insecticidal methyl carbamoyloxime acetylcholinesterase inhibitors, a straight-forward approach to estimating pKa values of a series of precursor oximes and thiohydroximates has been developed. The pKa values of oximes correlate well with the proton chemical shifts of the oximino proton (delta OH) in dilute dimethyl sulfoxide-d6 solution. The relationship pKa = 29.10 - 1.63 delta OH was developed from delta OH and pKa data for 20 compounds available either from the literature or derived experimentally from half-neutralization potentials (delta HNP). Using this relationship, pKa values of more than 200 hydroximino compounds were calculated. The relationship has been extended to also include phenols: pKa = 28.15 - 1.55 delta OH - 3.96I(phenol), where I(phenol) is an indicator variable indicating application of the equation to either a phenol [I(phenol) = 1] or an oxime [I(phenol) = 0].

[Information level about drugs prescribed to ambulatory patients in a university hospital]. / Nível de informação a respeito de medicamentos prescritos a pacientes ambulatoriais de hospital universitário.

Lack of information on medication is one of the main reasons why some 30-50% of patients fail to take their medicines as prescribed. To assess patient knowledge about prescribed drugs, outpatients from an internal medicine clinic in a teaching hospital were interviewed after medical consultation. Patients were asked to identify the name, indication, dosage, administration schedule, duration of treatment, side effects, and precautions. Patients' answers were compared to medical prescription or patients' medical records. Two hundred and sixty-four patients were interviewed, of whom 34% displayed satisfactory knowledge. In 31% of cases the drug name stated was incorrect, while in 19% the reported indication differed from that on the medical records. Dosage and administration schedules stated by patients disagreed with physician's instructions in 19% and 31% of cases, respectively. The results suggest that the majority of outpatients have sufficient knowledge for the safe use of prescribed drugs, under an ideal outpatient setting.

Sistema de grupos sanguíneos AB em felídeos neotropicais e compatibilidade com gatos domésticos / AB blood group system in neotropical felids and compatibility with domestic cats

O principal sistema de grupos sanguíneos reconhecido para gatos é o AB. Os felinos apresentam anticorpos naturais contra o antígeno do tipo sanguíneo a que não pertencem, o que torna os testes de compatibilidade e as tipagens sanguíneas importantes na prevenção de reações transfusionais. O objetivo deste estudo foi realizar a tipagem sanguínea de oito gatos-mouriscos (Puma yagouaroundi), oito jaguatiricas (Leopardus pardalis), sete gatos-palheiros (Leopardus colocolo), sete gatos domésticos (Felis catus) da raça Persa e oito gatos domésticos sem raça definida (SRD), bem como realizar testes de compatibilidade entre os tipos sanguíneos iguais das diferentes espécies, para avaliar a possibilidade de transfusões interespecíficas. A técnica empregada para a tipagem foi a hemaglutinação em tubos de ensaio. A ocorrência do tipo sanguíneo tipo A foi de 100% entre as jaguatiricas, os gatos-palheiros e os gatos Persas e de 85,72% entre os gatos SRD. A ocorrência do tipo B foi de 100% nos gatos-mouriscos e de 14,28% nos gatos SRD. Considerando os testes de compatibilidade sanguínea, 87,5% (n=4) das jaguatiricas foram incompatíveis com os gatos domésticos, 100% (n= 6) dos gatos-palheiros foram compatíveis com os gatos domésticos e 100% (n= 4) dos gatos-mouriscos foram incompatíveis com os gatos domésticos do tipo B.(AU)

The blood group system recognized for cats is AB. Antibodies against other blood types occur naturally in cats, which makes the compatibility tests and blood typing important for preventing transfusion reactions. Wild felids need blood transfusions in cases of diseases and when run over on highways. The aim of this study was to perform blood typing of eight jaguarundies (Puma yagouaroundi), eight ocelots (Leopardus pardalis), seven pampas cats (Leopardus colocolo), seven domestic cats (Felis catus) of Persian breed and eight non-pedigree domestic cats (Felis catus), and test compatibility among the different species with the same blood types, to evaluate the possibility of performing interspecific blood transfusions. We conducted the study from August to December. We used haemagglutination in test tubes for typing. The occurrence of blood type A was 100% among ocelots, pampas cats and domestic cats of Persian breed, while non-pedigree domestic cats showed 85.72%. The occurrence of type B was 100% for jaguarundis and 14.28% for non-pedigree domestic cats. Regarding blood compatibility tests, 87.5% (n= 4) of the ocelots were incompatible with domestic cats; 100% (n=6) of the pampas cats were compatible with domestic cats, while 100% (n=4) of the jaguarundis were incompatible with type B domestic cats.(AU)

Hematimetria manual e automática em jaguatiricas (Leopardus pardalis - Linnaeus, 1758) / Manual and automated blood cells count in ocelots (Leopardus pardalis - Linnaeus, 1758)

Aparelhos de automação, cujo uso está estabelecido na hematologia dos animais domésticos, ainda não são empregados rotineiramente em felídeos selvagens. Esse estudo objetivou avaliar a técnica automatizada na contagem de células sanguíneas de jaguatiricas (Leopardus pardalis), comparando-a com a técnica manual. Foram coletadas amostras sanguíneas de oito jaguatiricas, que se submeteram à contagem de eritrócitos, leucócitos, plaquetas e à determinação do volume globular pelo método manual padrão e por meio do aparelho BC - 2800 VET® com a configuração para gatos domésticos. Os resultados foram avaliados por meio do teste t para dados pareados, e as técnicas submetidas à análise de correlação de Pearson. A técnica automatizada demonstrou resultados estatisticamente semelhantes para eritrócitos e leucócitos. Apenas para volume globular houve diferença significativa entre as técnicas manual e automatizada, mas a correlação foi alta. Apesar de não haver diferença significativa entre as técnicas para plaquetas, a correlação foi baixa. Conclui-se que o aparelho BC - 2800 VET® com a configuração para gatos domésticos é uma técnica confiável na realização do eritrograma e do leucograma para jaguatiricas. Para a determinação do parâmetro volume globular, o aparelho pode ser utilizado, desde que se faça a correção. Para a contagem de plaquetas, a técnica manual é recomendada.(AU)

Automated equipment, whose use is established in hematology of domestic animals, is not yet routinely used in blood cells count of wildlife, due to lack of studies that validate its use. The purpose of this study was to evaluate the automated technique for blood cells count of ocelots (Leopardus pardalis), comparing it with the manual technique. Blood samples were collected from eight ocelots, which were submitted to counting of erythrocytes, leukocytes, platelets and packed cell volume by the standard manual method and by the device VET ® 2800 BC with the configuration for domestic cats. The results were evaluated using the t test for paired data and the techniques submitted to Pearson correlation. The automated technique showed statistically similar results to erythrocytes and leukocytes. Significant difference was found only for packed cell volume between the manual and automated techniques, but the correlation was high. Although there was no significant difference between the techniques for platelets, the correlation was low. We concluded that the 2800 BC VET ® device with the configuration for domestic cats is a reliable technique in performing the erythrocyte and leukocyte counts for ocelots. The device may be used to determine packed cell volume, provided the correction is made. The manual technique is recommended for the platelet count.(AU)

Effects of ethanol on the osteogenesis around porous hydroxyapatite implants.

Alcohol consumption compromises bone tissue, and thus may either impair or stop the fixation and maintenance of osseointegrated implants. To evaluate the effects of 5% and 15% ethanol on bone neoformation around porous hydroxiapatite implants. Fifteen rats were separated into 3 groups of 5 animals each: control (CT); 5% alcohol (A); and 15% alcohol (AA). After four weeks of ethanol consumption, the rats received porous hydroxiapatite implants into surgically made cavities in the femur. After surgery, the animals continued to consume ethanol until day 90 of the experiment, when they were euthanised and their femurs removed for histological processing. Bone tissue was found around the ceramic specimens of all the animals. The largest volume of neoformed bone around ceramic specimens occurred in the CT group, and the smallest in the AA group, followed by the A group. It was concluded that ethanol consumption produced a negative effect on osteogenesis around hydroxyapatite implants. Even small doses, such as the 5% ethanol dilution can interfere with bone repair.

The objective of this work is to show an alternative technique for maxillary complete rehabilitation with implant-supported denture with ceramic zirconia infrastructure.

Assessment of the quality of compounded fluconazole capsules marketed in the region of Araraquara (SP, Brazil) / Avaliação da qualidade de cápsulas de fluconazol manipuladas comercializadas na região de Araraquara (SP, Brasil)

O controle de qualidade de fármacos desempenha um papel importante na saúde pública ao garantir segurança e eficácia de medicamentos. No sistema de saúde pública,as farmácias magistrais também são importantes. Elas fornecem medicamentos personalizados como produtos dermatológicos e doses específicas para crianças.Infelizmente, muitos casos de produtos magistrais fabricados fora do padrão mínimo de qualidade têm sido relatados no Brasil. Neste trabalho, a qualidade das cápsulas magistrais de fluconazol 150 mg foi avaliada e os resultados foram comparados com os valores recomendados pela Farmacopeia Brasileira. Os resultados sugerem que é possível manipular produtos que satisfaçam as especificações farmacopeicas, mas estes ainda mostram que há farmácias magistrais onde o controle de qualidade é deficiente ou inexistente. O fluconazol é um fármaco importante no tratamento de infecções fúngicas. Seu uso como forma farmacêutica manipulada sem elevados padrões de qualidade é fortemente relacionado com a falha terapêutica e intoxicações, assim como o surgimento de microorganismos resistentes. Portanto, a necessidade de melhoria dos processos nas farmácias magistrais se torna mais enfático. Existem métodos validados que podem ser utilizados com sucesso para a análise de rotina de controle de qualidade e que podem ser implementados por qualquer farmácia de manipulação...

The quality control of drugs has an important role in public health, in ensuring the efficacy and safety of medicines. In the public health system, compounding pharmacies play a vital part. They provide medicines tailored to the individual patient, for example dermatological products and specific doses for children. Unfortunately, many cases of compounded products falling below the minimum quality standard have been reported in Brazil. In this study, the quality of compounded 150 mg fluconazole capsules was assessed and the results were compared with values stipulated in the Brazilian pharmacopoeia. The results suggest that, while it is certainly possible to prepare products meeting pharmacopoeial specifications, there are pharmacies where the quality control is deficient or nonexistent. Fluconazole is an important drug in combatting fungal infections. The use of fluconazole in dosage forms manufactured without high standards of quality control is strongly linked to treatment failure and cases of intoxication, as well as the emergence of resistant microorganisms. This highlights the urgent need for process improvement in compounding pharmacies. There are validated methods that can be successfully employed for routine quality control analysis that can be implemented by any compounding pharmacy...

A comparative genomics strategy for targeted discovery of single-nucleotide polymorphisms and conserved-noncoding sequences in orphan crops.

Completed genome sequences provide templates for the design of genome analysis tools in orphan species lacking sequence information. To demonstrate this principle, we designed 384 PCR primer pairs to conserved exonic regions flanking introns, using Sorghum/Pennisetum expressed sequence tag alignments to the Oryza genome. Conserved-intron scanning primers (CISPs) amplified single-copy loci at 37% to 80% success rates in taxa that sample much of the approximately 50-million years of Poaceae divergence. While the conserved nature of exons fostered cross-taxon amplification, the lesser evolutionary constraints on introns enhanced single-nucleotide polymorphism detection. For example, in eight rice (Oryza sativa) genotypes, polymorphism averaged 12.1 per kb in introns but only 3.6 per kb in exons. Curiously, among 124 CISPs evaluated across Oryza, Sorghum, Pennisetum, Cynodon, Eragrostis, Zea, Triticum, and Hordeum, 23 (18.5%) seemed to be subject to rigid intron size constraints that were independent of per-nucleotide DNA sequence variation. Furthermore, we identified 487 conserved-noncoding sequence motifs in 129 CISP loci. A large CISP set (6,062 primer pairs, amplifying introns from 1,676 genes) designed using an automated pipeline showed generally higher abundance in recombinogenic than in nonrecombinogenic regions of the rice genome, thus providing relatively even distribution along genetic maps. CISPs are an effective means to explore poorly characterized genomes for both DNA polymorphism and noncoding sequence conservation on a genome-wide or candidate gene basis, and also provide anchor points for comparative genomics across a diverse range of species.

Thiodicarb.

Dimethyl N,N'-[thiobis(methyliminocarbonyloxy)] bis-(ethanimidothiolate), C10H18N4O4S3, is an example of a sulfenylated biscarbamate insecticide. The molecule has an approximate twofold axis through the central S atom which joins the two methyliminocarbonyloxyethanimidothiolate units. One of the two arms is planar in the crystal. Semi-empirical geometry optimization for an isolated molecule favors a model with both arms planar and, thus, crystal packing may be responsible for the observed non-planarity in one arm. Bond lengths and angles have similar values to those of the 'monomeric' carbamate insecticide methomyl.
