The vaquejada race is a sport with animals which has the greatest socio-economic impact in Brazil and is responsible for generating an intense cultural and economic movement. However, this activity has been the subject of questions about well-being involving the environmental and mental comfort conditions offered to equine and cattle interactions. It is necessary to perform technical evaluations of the cattle involved on the basis of scientific study to better understand the processes of sport and, with this, promote their evolution on good welfare practices in the 21st century. Therefore, to test the hypothesis that the use of the official rules of the vaquejada where cattle use a protective harness on the tail protects the cattle’s tail from injuries in this region that compromise health. Before, during and after races, a study was developed that aimed to perform a general and radiological clinical evaluation in the proximal coccygeal region in cattle that ran in a modern cattle stall. Forty male bovines were evaluated (average: 2 year-old and 420 kg). Oxen were subjected to clinical and radiological examination before and after racing with official rules. Results of the clinical and radiological evaluations performed by veterinarians, did not observe clinical occurrences before and after the races in the 40 cattle evaluated. The increase in heart and respiratory rates was a reflection of temporary management stressors, as the animals returned to the feeding/rumination/interaction pattern after running in the rest pen. The radiographic findings in the tail, represented by the reduction of the intervertebral space and areas of subcutaneous radiolucency, suggest technical artifacts derived from

Advances in Bioscience and Biotechnology 2017年第10期8卷 343-360页

作者： Juliana Ferrari ferreira Secato brunno ferreira dos Santos Alexandre Nunes Ponezi Elias Basile Tambourgi School of Chemical Engineering (FEQ) Department of Chemical Systems Engineering (DESQ) University of Campinas Campinas Brazil Department of Chemical and Materials Engineering (DEQM) Pontifical Catholic University of Rio de Janeiro Rio de Janeiro Brazil Research Center for Chemistry Biology and Agriculture (CPQBA) University of Campinas Campinas Brazil

Bacillus subtilis was investigated as production of biosurfactant using a combination based on waste of candy industry and glycerol from biodiesel production process as only substrate. The experimental design chosen for optimization by response surface methodology was a central composite rotatable design (CCRD) and dry weight (DW) and crude biosurfactant (CB) concentrations were selected as responses in analysis. Two techniques were implemented response surface methodology (RSM) and artificial neural network (ANN). First challenge of study was to assess the effects of the interactions between variables and reach optimum values. With the CCRD results, RSM and ANN models were developed, optimizing the production of biosurfactant. The correlation coefficients (R2) of RSM models explained 88% for DW and 73% for CB of the interactions among substrate concentrations, while ANN models explained 99% for DW and 98% for CB, demonstrating that developed ANN models were more accurate and consistent in predicting optimized conditions than RSM model. The maximum DW and CB produced in the optimum conditions were 25.60 ± 5.0 g/L and 668 ± 40 mg/L, respectively. The crude biosurfactant also showed applications in cases of oil spreading in water due to clear zone produced in Petri dishes assays.

Only Spondylodiscitis? A Clinical Case of Multiple Septic Embolization

引用

Case Reports in Clinical Medicine 2016年第10期5卷 353-357页

作者： Rita aguiar Manuel ferreira Gomes Elisabete Bento Guerreiro Tiago Marques Carla Santos Department of Immunoallergology Hospital de Santa Maria Centro Hospitalar Lisboa Norte Lisbon Portugal Department of Internal Medicine Hospital de Santa Maria Centro Hospitalar Lisboa Norte Lisbon Portugal Department of Infectious Diseases Hospital de Santa Maria Centro Hospitalar Lisboa Norte Lisbon Portugal

Background: Spondylodiscitis and spinal epidural abscesses are rare pathologic entities, but increasing in incidence. Group G beta hemolytic Streptococcus has been recently described associated with human infections. They often present clinically in a non-specific fashion, a fact which can lead to diagnostic delay, with serious consequences for the patient. Case Report: An 80-year-old man was admitted to the hospital with complaints of fever for three days, dysuria, hematuria, and back pain. Both septic embolizations and spondylodiscitis due to Group G beta hemolytic Streptococcus were detected. The patient was successfully treated with intravenous penicillin G for eight weeks, followed by oral amoxicillin for five months. Discussion: In all patients with spondylodiscitis, infective endocarditis should be considered, particularly in patients with heart valve disease history, since spondylodiscitis may be the presenting sign of an infective endocarditis. A high level of suspicion is therefore necessary in order correctly diagnose such entities as quickly as possible. The present case illustrates the pathogenic potential of group G streptococci in spondylodiscitis and native valve endocarditis.

Background: A healthy normal skin is essential for a person’s physical and mental well being. It is an important aspect of their sexual attractiveness, a sense of well being and a sense of self confidence. Vitiligo is an acquired depigmentation disorder of skin affecting 1% - 4% of the world population. Neither life threatening nor symptomatic (except that depigmented patches burn easily when exposed to the sun) the effects of vitiligo can be cosmetically and psychologically devastating. Because the disease is still not understood, there is a plethora of different treatments approaches, but they are largely unsatisfactory from patient’s perspective. Objective: To report the outcomes from oral use of an infusion of leaves of Solanum paniculatum L., Jacaranda brasiliensis and Sonchus oleraceus for treatment of vitiligo. Ethical issues: Study approved by the Research Ethics Committee of Hospital Federal dos Servidores do Estado do Rio de Janeiro (CAAE: 32143314.9.0000.5252). All participants confirmed the condition of volunteer by signing the Informed Consent Form. Methods: From October 2014 to October 2015 twelve subjects consumed daily four glasses (800 ml) of proposed phytotherapeutic preparation. Results: All subjects were highly satisfied about their outcomes. Total depigmentation was considered as a positive outcome because it is cosmetically acceptable. Total depigmentation was observed in presence of 80% or more of depigmenteted patches. Conclusions: The phytotherapeutic preparation proposed is effective on treatment of depigmenteted patches in vitiligo.

BACKGROUND： Fibrolamellar hepatocellular carcinoma （FLHCC） is a rare disease with an indolent behavior. Its prognosis is better than that of patients with hepatocellular carcinoma. The authors present their experience with resection of FLHCC. METHODS： Twenty-one patients with FLHCC were treated at our institution between 1990 and 2012. Of these patients, 14 were subjected to resection of the tumor. Patient demographics, medical history, results of imaging studies and laboratory tests, surgical data, and pathologic findings were evaluated. RESULTS： The median age of the patients at the diagnosis of the tumor was 20 years and 14 patients were female. None of the patients had tumor-associated chronic liver disease or cirrhosis. The mean tumor size was 12.8 cm （range 6-19） and 18 patients had a single liver nodule. Fourteen patients were subjected to hepatectomy and six of them had lymph node metastases resected. Pathologic evaluation revealed that 5 （35.7%） patients had major vascular invasion. Tumor recurrence was seen in 8 patients （66.7%）, during a follow-up. The median survival time for patients who were subjected to resection was 36 months. The 5-year overall survival rate and disease free survival rate were 28.0% and 8.5%, respectively. Univariate analysis showed that vascular invasion was the only variable associated with the disease free survival ***： Despite an aggressive treatment, patients with FLHCC presented unexpected low survival rates. It seems that an underestimated malignant behavior is attributed to this disease, and that the forms of adjuvant treatment should be urgently evaluated.

The cementoblastoma is a very rare odontogenic neoplasm characterised by the formation of cementum-like tissue in connection with the root of a tooth. An 18-year-old boy was referred to the Clinic of Oral Pathology of the School of Dentistry, Universidade Federal de Minas Gerais, Brazil, complaining of an irradiating, itching pain from the region of the lower right first molar. He reported that the symptoms began three months prior, with a gradual increase in intensity during this period. The pain episodes were of short duration, with characteristics of toothache originating from the pulp. Upon intra-oral clinical examination, an open bite and slight increase in volume at the buccal alveolar region of the lower right first molar was observed. He also reported palpation and percussion pain symptoms in this region. Electrical, heat and cold pulp vitality tests were performed, and the tooth was vital. Periapical and panoramic radiographs showed radiolucent images with diffuse, poorly defined borders at the mesial root periapex extending to the interradicular region suggesting an inflammatory periapical lesion. In this early presentation, the three-dimensional image was fundamental to the final diagnosis of cementoblastoma.

To evaluate the therapeutic effects of bone marrow-derived CD11b+CD14+ monocytes in a murine model of chronic liver *** liver damage was induced in C57BL/6 mice by administration of carbon tetrachloride and ethanol for 6 mo. Bone marrow-derived monocytes isolated by immunomagnetic separation were used for therapy. The cell transplantation effects were evaluated by morphometry, biochemical assessment, immunohistochemistry and enzyme-linked immunosorbent ***11b+CD14+ monocyte therapy significantly reduced liver fibrosis and increased hepatic glutathione levels. Levels of pro-inflammatory cytokines, including tumor necrosis factor-α, interleukin (IL)-6 and IL-1β, in addition to pro-fibrotic factors, such as IL-13, transforming growth factor-β1 and tissue inhibitor of metalloproteinase-1 also decreased, while IL-10 and matrix metalloproteinase-9 increased in the monocyte-treated group. CD11b+CD14+ monocyte transplantation caused significant changes in the hepatic expression of α-smooth muscle actin and *** therapy is capable of bringing about improvement of liver fibrosis by reducing oxidative stress and inflammation, as well as increasing anti-fibrogenic factors.
