本研究综合了杂草生态属性和谷物碳氮稳定同位素分析这两种识别农作物生长条件和耕种实践的方法,以评估植物考古研究在推断古代作物生产系统强度的潜力。法国上普罗旺斯(Haute Provence)现代有机农业以适应低肥力土壤的作物栽培为特色,采用轮作的方式,很少甚至几乎不施肥。在该地区60处农田样带的杂草样方调查显示,植物群落的变化主要与地理区域的差异相关。普罗旺斯的杂草生态属性数据和之前调查的西班牙西北部阿斯图里亚斯(Asturias)集中管理的斯皮尔特小麦明显有别。杂草生态数据表明,阿斯图里亚斯土壤肥力较高,人类对土地的干预更多。农作物氮稳定同位素值也表明,阿斯图里亚斯与上普罗旺斯存在强化型施肥和长期基本不施肥的栽培模式差异。我们将上普罗旺斯和阿斯图里亚斯的杂草生态属性和谷物同位素值所反映栽培强度的新模型应用到罗马尼亚的锡吉什瓦拉(Sighisoara)、土耳其的卡斯塔莫努(Kastamonu)这两个现代地区作物管理体制的测试中,成功地区分了锡吉什瓦拉的精耕细作和卡斯塔莫努的粗放生产模式。这一新模型在欧洲中部新石器时代植物考古中的应用表明,早期农业趋向于集约型生产,并可能已经有了施肥的实践,但研究结果也显示了新石器时代农业生产方式的多样化态势,为探索栽培强度提供了新路径。

The Tityus serrulatus scorpion is considered the most dangerous scorpion in Brazil and is responsible for several cases of human envenomation annually. In this study, we performed transcriptome profiling of the T. serrulatus venom gland. In addition to transcripts with housekeeping functions, such as those related to protein synthesis, energy supply and structural processes, transcripts from thirty-five families of venom peptides or proteins were identified. These transcripts included three new complete sequences of toxins and more than a dozen putative venom gland proteins/peptides. The venom gland transcriptome profile was verified by comparison with the previously determined proteomic profile. In conclusion, this transcriptome data provides novel insights into the putative mechanisms underlying the venomous character of T. serrulatus. The collected data of scorpion transcripts and proteins/peptides described herein may be an important resource for identifying candidate targets of molecular therapies and preventative measures.

Mammary tumors are very common in female dogs and its prognosis varies significantly according to the tumor invasion degree. Myoepithelial layer destruction is considered a differential diagnosis parameter of in situ from invasive lesions in human breast cancer. Aiming to evaluate the immunohistochemical expression of p63, a protein specifically expressed by myoepithelial cells of mammary gland, and its correlation with p53 expression, 10 adenomas and 20 carcinomas with and without metastasis of canine mammary gland were studied. There was no significant difference between adenomas and carcinomas for both proteins staining, however, the percentage and continuity of staining was lower in metastatic carcinomas. There was no correlation between p53 and p63 expression, but the higher values of p53 staining were found in carcinomas, according to previous studies. Results showed that p63 is specifically expressed also in myoepithelial cells of canine mammary gland. However, in order to ensure its use as a prognostic marker in canine mammary tumors, further studies involving a higher number of samples should be conducted.

Total spectrofluorimetry associated with Principal Component Analysis (PCA) was used to discriminate samples of vegetable oil and animal fat. In addition, a multivariate calibration model was developed that combines spectroflurimetry with Partial Least Squares (PLS) for prediction of concentration of animal fat in mixture with vegetable oil. The multivariate calibration model had an R2 value of 0.98098, which indicates the accuracy of the model. This method has potential application in the control of quality of raw material for production of biodiesel. The control of the concentration of animal fat is important because animal fat is more susceptible to oxidation than vegetable oil. Furthermore, high concentrations of animal fats may increase electricity costs for biodiesel production due to the high melting points of saturated fats that solidify at room temperature and cause the fouling and clogging of pipes.

Symptoms of Tar Spot Complex (TSC) in corn appear in the form of black spots surrounded by a chlorotic halo known as fish-eye. The crop with these symptoms was found at San Pablo Autopan, Estado de Mexico. The stromal region of foliar lesions was cut longitudinally, showing perithecia, asci and ascospores typical of Phyllachora maydis. The results were confirmed by PCR-ITS with ITS 1 and ITS4 initiators, cloned by pJET, before being sequenced and compared against NCBI’s data base. Phyllachora identity was confirmed. This is the first report where TSC pathogen has been detected under conditions that had not been previously reported, for instance, at 2600 meters above the sea level.

In this work, a modification of the sugarcane bagasse is performed, in order to obtain organic catalysts. The bagasse analysis is performed using X-ray diffraction (XRD) and Fourier Transformer Infrared Spectroscopy (FTIR), which indicated that characteristic peaks determined its chemical compounds. In addition, Scanning Electron Microscopy (SEM) is used to know the morphology. Finally, a discoloration test is conducted on an azo compound (methylene blue) in an aqueous medium, obtaining an efficiency of 98.6%.
