Background: The concomitant presence of intestinal parasite infections (IP) and tuberculosis (TB) has relevance. M. tuberculosis immune response is associated with type 1 T helper cell (Th1) while IP is associated with type Th2 cell. However, there are several contradictory reports on cytokine production under coinfection and this could be in association to the mycobacterial antigens used in the studies. Aim: To get insight into the effects of different M. tuberculosis-specific antigens (ESAT-6/CFP-10 and 38 kDa/CFP-10) in generating of appropriate cytokines on peripheral blood mononuclear cells of IPTB co infected patients. Method: ELISA assessed IFN-γ and other 16 cytokines production and plasm IgE. In 18 months, we documented demographic, economic, clinical characteristics and IP frequency in individuals from Brazil. Results: An overall 10/35 (28.5%) were IPTB co infected and 40/76 (52.6%;p = 0.024) asymptomatic intestinal parasite infected community controls (IPCC). Endo-limax nana (40%) and Entamoeba coli (22%), were the most nonpathogenic protozoan identified and Entamoeba histolytica, Giardia intestinalis, Ascaris lumbricoides and Strongyloides stercoralis were the pathogenic species (40%). IgE was higher in IPCC (p = 0.036). Cytokine profiles were significantly biased toward a Th2 type IL-5 (p = 0.001) and IL-13 (p = 0.033), pro-inflammatory GM-CSF (p = 0.019) and borderline lower IL-1β in IPTB, all associated with ESAT-6/CFP-10, while IL-7 was borderline lower, but 38 kDa/CFP-10 associated;as well as IL-8 higher (p dent IPTB coinfection did not exert a significant inhibitory effect in IFN-γ production in response to either of the two antigens, but the partial discrepancy in Th1/Th2 response, is associated with the antigen priming cells.

This study was conducted to evaluate the physiological quality of forage seeds after passage through the gastrointestinal tract of cattle, as well as the emergence of seedlings derived from these seeds. Three Fabaceae species were used: tropical kudzu, leucaena and calopo. One hundred grams of seeds of each species were offered, separately, to five bovines. After the start of the dispersion, the faeces of the animals were collected every 6 hours, in a total of 72 hours, being taken to the greenhouse immediately after each collection. The study evaluated the total number of seedlings in the stool, the lengths of roots and aerial parts, as well as the natural and dry seedling weight thirty days after the disposal of the faeces in the greenhouse. The experimental design consisted of randomized blocks, with twelve treatments (sampling periods) and five replications (cattle). The best performance for the total number of seedlings in the faeces of cattle was observed in the kudzu species. The length of the root, length of the aerial part and dry matter seedling weight was observed in the leucaena species, followed by kudzu. The calopo showed low results for all variables due to the high degradation of the seeds.

Respiratory Muscle Strength Evaluation in Healthy Adult and Elderly Women—Respiratory Muscle Strength Assessment in Adult and Elderly

引用

Health 2018年第8期10卷 1031-1036页

作者： Maria Clara de souza Pereira Gama Maciel Cássio daniel Araújo da Silva Fernanda Figueiroa Sanchez Jamilly Reboucas demosthenes Marques Pablo Costa Cortez Camila Miriam Suemi Sato Barros do Amaral Naylla Morais de souza Roberta Lins Goncalves Federal University of Amazonas-UFAM ManausBrazil

Measurement of respiratory muscle strength is performed through static measurements of maximal respiratory pressures and is an important tool for determining the existence and prognosis of neuromuscular and pulmonary disorders, such as weakness or fatigue of this musculature. Objectives: To evaluate and compare respiratory muscle strength among healthy adult and elderly women. Methods: A total of 163 healthy women were recruited through convenience sampling at the family centers of the city of Manaus (AM, Brazil), divided into two groups: adult women (age 20 - 59 years) and elderly women (over 60 years of age). The evaluation was performed by Manovacuometry, in order to measure the maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP). For statistical analysis we used the Student’s T test, considering significant p value ≤ 0.05. Results: The final sample consisted of 116 adult women and 47 elderly women. The mean age in the group of women between 20 - 59 years was 44.5 ± 12 and the elderly group was 65 ± 6.6. MIP values in adult women were significantly higher when compared to the elderly (−108 ± 5.3 cmH2O × −79.5 ± 4 cmH2O, p = 0.0014, respectively). The same behavior was observed in the evaluation of MEP (87.1 ± 2.9 cmH2O in adults and 69.8 ± 3.5 cmH2O in the elderly;p = 0.0008). Conclusion: The results indicate that inspiratory and expiratory muscle strength is lower in older women, suggesting that the aging process tends to interfere with those muscles, resulting in altered respiratory system function.

The search for therapeutic agents that will provide the ground for man and an improvement in their quality of life is ceaseless. The nerol (cis-2,6-dimethyl-2,6-octadien-8-ol) is a monoterpene which can be found in various medicinal plants as Lippia spp and Melissa officinalis L. The objective of this study was to analyze the acute effect of nerol in the central nervous system (CNS) by performing behavioral tests in mice (open field, elevated plus-maze, light/dark and rota rod tests). We used male albino mice (Mus musculus), Swiss variety, adult with 2 month-old. The animals were divided into five groups (n = 8) for each experimental protocol, and they were administered intraperitoneally (i.p.), respectively, Tween 80 0.05% dissolved in saline solution 0.9%, nerol (30, 60 or 90 mg/kg) or diazepam (2 mg/kg). In the open field test, all groups treated with nerol showed a significant decrease in motor activity (number of crossings, rearings and groomings) when compared with vehicle group. In the elevated plus-maze test, nerol groups significantly increased the number of entries and time of permanence in the open arms when compared with vehicle group. In the light-dark test, nerol groups showed a significant increase the time of permanence in the room clear when compared with vehicle group. In the rota rod test, the groups treated with nerol didn’t show modification in time spent and number of falls in the revolving bar when compared with vehicle group. These results indicate a possible anxiolytic effect of nerol in mice.

Pyoderma gangrenosum is a rare ulcerative cutaneous disorder commonly associated with systemic diseases such as inflammatory bowel diseases. This paper reports a case of pyoderma gangrenosum affecting the mouth and the skin associated with ulcerative colitis. A Medline search in English literature from 1961 to 2012 revealed only 11 documented cases of pyoderma gangrenosum with oral involvement. Previous reported cases of oral cavity involvement have shown that the most common sites of manifestation are the tongue, palate, and tonsillar fauces. This case emphasizes the importance of including inflammatory bowel diseases and their manifestations in the differential diagnosis of ulcerative lesions in the oral cavity.

This study aimed to analyze the economic feasibility of canola production (Brassica napus var oleifera) for the region Campos Gerais-PR. We interviewed eight producers, and used information from four of them for economic analysis of agricultural crops in 2012, 2013 and 2014. The variables analyzed were: grain production cost, economical analysis (hurdle rate, net present value, internal rate of return, payback, lucratively index, profitability index and sensitivity analysis) and vegetable oil production costs. We compared the performance of canola, wheat (Triticum aestivum)—as the main crop in the autumn/winter—and soybean (Glycine max)—by liquidity in the world market. It was concluded that although the economic analysis indicates superior results of canola production compared to the wheat crop and vegetable oil production is more attractive financially than soybean, but the culture of canola is still insignificant in the region of Campos Gerais (PR). The producers interviewed pointed to limit the expansion of culture financing the limited farming, production technology in consolidation, the need for machine adjustments and canola be host of the white mold disease (Sclerotinia sclerotiorun).

Virulence Factors and Biofilm Formation in Vancomycin Resistant Enterococcus faecalis and Enterococcus faecium Isolates in Brazil

引用

Advances in Microbiology 2023年第6期13卷 299-314页

作者： Bárbara de Azevedo Ramos Marília Manta Manta Sivoneide Maria da Silva Rafael Artur Queiroz Cavalcanti de Sá Natália Lira de souza henrique Douglas Melo Coutinho Márcia Vanusa da Silva Túlio Diego da Silva Maria Tereza dos Santos Correia Maria Betânia Melo de Oliveira Universidade Federal de Pernambuco Pernambuco Brazil Universidade Regional do Cariri Ceará Brazil Instituto de Tecnologia de Pernambuco Pernambuco Brazil

In this work, we evaluated biofilm formation of Vancomycin Resistant of E. faecalis and E. faecium (VRE) in different culture media and adhesion substrate, as well as cellular hydrophobicity and presence of virulence genes. For this, 35 isolates were collected from a public hospital in Recife, Pernambuco, Brazil and identified by the Matrix-Assisted Laser desorption Ionization - Time-of-flight - Mass Spectrometry (MALDI-TOF-MS) technique. Biofilm formation was analyzed by the Crystal Violet (CV) method and fluorescence microscopy, cellular hydrophobicity by hydrocarbon interaction and the presence of gelE, esp and asa1 genes by Polymerase Chain Reaction (PCR). 12 isolates were identified as E. faecalis and 23 as E. faecium. Most were obtained in Coronary Units (40.0%) and Intensive Care Unit (31.4%). E. faecium isolates were more resistant to the antibiotics tested than E. faecalis;however, E. faecalis stood out as a biofilm producer. Regarding the presence and gene frequency, it was observed that gelE (54.3%) and esp (54.3%) were the most prevalent, followed by asa1 (22.9%). When comparing the gene frequency, it was observed that gelE and esp were predominant (48.6% for both species), while asa1 was more frequent in E. faecalis (20.0%). The data presented here are worrying, because they reveal the virulence potential of isolates VRE, which contributes to the dissemination and persistence of these pathogens in the hospital environment.

Gas irradiation in research nuclear reactors is an important way to produce radionuclides. Although some nuclear reactors centers offer this type of service, there are few publications about capsules to irradiation of gaseous samples. This paper describes a method to fabricate and evaluate aluminum capsules to irradiate gaseous samples in nuclear reactor. A semi-circular slotted die from a hydraulic presshead was modified to seal aluminum tubes. The aluminum capsules were subjected to leak detection tests, which demonstrated the accordance with standard ISO 9978.
