The aim of this study was to evaluate the visible loss of sugar cane and the damage to the knuckles, using the John Deere 3520 harvester on three different travel speeds (3.0;4.0 and 5.0 km·h-1), in DIC with five repetitions in Campos dos Goytacazes, Rio de Janeiro/Brazil. Each treatment was composed by six lines of harvested cane stumps, with a length of 290 m each. In these six lines, the remains of sugar cane left in the field were collected by placing the sampling frame in two central lines every 50 m, and separating 40 m of edge. The sampling area was surrounded by 2 m wide and 10 m long, totaling 20 m2. To calculate the damage to stumps, a visual methodology by [1], was used, which classifies the damage grade, ranging from 1 to 4. Fifty stumps were assessed randomly for each speed, in a sampling area of 1800 m2. The data were submitted to ANOVA and Tukey test at 5%, in order to compare the effect of different speeds on the losses and damages. There was no significant difference regarding the loss or damage by comparing the different speeds. Therefore, it is more advantageous to use the speed of 5.0 km·h-1, harvesting more in less time and causing the same level of damage.

Cryofrequence is the combination of cryotherapy with radiofrequency, which promotes a “thermal shock” to the tissue, working simultaneously to skin flaccidity and localized adiposity. The efficacy of dermatological and hypodermic cryofrequency treatment was evaluated. This study reports the case of a 45-year-old woman with complaints of flaccidity and fat located in the infra-umbilical region in the preoperative period of abdominoplasty. The evaluation was performed before and after treatment through evaluation protocols, ultrasound examinations and histological findings through optic microscopy, microfocal and immunohistochemical analysis. The treatment was performed in 4 sessions, with a weekly application, using the BHS 156 FULL®—BODY HEALTH BRASIL®apparatus, the parameters were temperature of -10°C, power in 70%, duration of 8 minutes. After the surgical procedure, parts of treated and untreated abdominal tissues were removed for evaluation. In the tests performed, significant destruction of adipocytes was detected, with consequent reduction of fat and greater expression of caspase-3 in the treated tissue, being constated the macrophage increase by CD68 expression. There was improvement in flaccidity, evidenced by the significant increase in the number of fibroblasts and inflammatory cells positive for Ki67, bringing more quantity and better quality to the collagen.

Cellulose nanocrystals (NCC) and cellulose nanofibrils (CNF) were obtained by a single step process, with synergy between 64% sulfuric acid hydrolysis and high shear from ultra-turrax stirring, which is an advantageous process for disintegrating cellulose microcrystalline and also may improve the hydrolysis process. The surface modification on the cellulose was performed by the sol-gel process, in which the sulfate groups from hydrolysis were replaced by nanoparticles of zinc oxide, which led to the increase of up to 54°C Tonset, according to thermogravimetric analysis (TGA) results. The morphology and crystallinity degree were characterized by Helium Ion Microscopy (HIM), atomic force microscopy (AFM) and X-ray diffraction. In addition, the ZnO band was observed in Fourier transform infrared spectroscopy, furthermore, the change in the zeta potential confirmed the cellulose modification. The changes in the values of proton spin-spin relaxation time for the systems showing the confined hydrogen in the rigid domains, confirmed the results observed with the aforementioned techniques, for both cellulose after hydrolysis and ZnO modified cellulose, suggesting that ZnO disrupted crystal formation in cellulose.

The upland rice is grown in most Brazilian states. However, in many of them the yield obtained is low. The choice of cultivar more suited to a particular environment can contribute to increased productivity of this crop. This research aimed to evaluate the performance of a hybrid cultivar of upland rice (Ecco) and five conventional cultivars (BRS Monarca, BRS Primavera, AN Cambará, BRS Sertaneja and BRS MG Curinga) in two environments (Vilhena and Cerejeiras). The tests were conducted in the agricultural year 2010/2011. We evaluated the following characteristics: tillering, panicle number per unit area, number of filled grains per panicle sterile, mass of grains per panicle, 1000 grain weight, grain yield (kg·ha-1) and whole grain yield. There was no cultivar x environment interaction for all traits. Greater tillering, higher panicle number per area, higher productivity and yield of whole grains in the municipality of Cerejeiras were observed, while the highest number of sterile grains per panicle was obtained in Vilhena. The hybrid Ecco highlighted in relation to all other cultivars is in relation to tillering, panicle number per area and grain yield. The municipality of Cerejeiras is the most suitable for the cultivation of upland rice.

The objective of this study is to identify and collect information on local agriculture products and identify local potential agriculture and livestock that can attract foreign investments. Used Stratified Random Sampling and data was collected from both primary and secondary data (both quantitative and qualitative data. The data analyzed used qualitative and quantitative analysis. The supply chain analysis was carried out to develop a description of the value chain to identify potential high-value market areas and current and potential products in the domestic and export markets. The results of the study revealed that most farmers in the research location grow different types of crops and livestock. In particular for Aileu and Ainaro where most of the areas are up-land, therefore, horticulture crops (mustard, cabbage, carrots, and tomato) and coffee are dominated in these areas. For Manufahi, some parts are lowland areas, where most crops grown are maize, cassava, and paddy rice. The study reveals that local potential agriculture products and livestock in the municipalities of Aileu, Ainaro, and Manufahi are vegetable, coffee, maize, and paddy rice, banana, shallot, tangerine, cabbage, carrot, cattle, mung-bean, and banana. To accelerate economic growth, in these municipalities, there is a need to modernize agricultural production, requiring markets for both inputs supply and for the sale of output products. Opportunities to increase the productivity of these products are feasible and this can be done through the use of high-variety seeds and better farm management, and the government and private sector can play an important role in improving productivity as this will have a further implication in improving food security.

Background: Oxidative stress and inflammation are related to the pathophysiology of diabetes mellitus (DM), being involved in the development of micro-and macrovascular complications. Physical activity is beneficial for DM patients, but little is known about the relationship between redox and inflammation biomarkers and the level of physical activity in these patients. Based on this, this research aims to evaluate the effects of physical activity level on redox stress parameters and inflammatory markers in T2DM patients. Methods: Eighty-four patients with T2DM were divided according to their physical activity level: group A (n = 48), sedentary;group B (n = 11) active (3 times a week, 150 min) and group C (n = 25), highly active (5 times a week, 150 - 300 mins, at least). Anthropometric and biochemical parameters, superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities, as well as GSH, sRAGE and ICAM-1 levels were assessed. Results: Glycated haemoglobin, total cholesterol, and LDL-cholesterol levels were lower in the highly active group in comparison to other groups. Plasma SOD activity was higher in group C compared to Group A, while ICAM-1 levels were significantly higher in group B when compared to other groups. Conclusion: Our results suggest that the practice of physical activity is beneficial to T2DM patients, especially at high volume and frequency.

The aim of the study is to assess the factors that influence the sustainability of agricultural development. The study was carried out in the municipality of Bobonaro for about four months, from July to October 2021. Slovin’s method was used to determine the sample size, with a desired percentage of 10% of the total population. Thus, 154 producers were interviewed as respondents and key persons in the area of agriculture. The variables interviewed are the main factors of agricultural productivity and the factors that affect sustainable agricultural development. The results of the descriptive statistical analysis of the data showed that about 94.87% of the respondents’ productive area is in operation, with an average of 1.84 ha per respondent and the abandoned area around 0.11 ha per respondent. The average value of rice production is 2.38 ton per ha and corn 1.07 ton per ha. About 87% of producers raised the main types of animals such as cattle, pigs, goats with an average density of 2 to 5 animals per establishment. About 61% of producers have access to the market at a normal price for agricultural products. The factors that hinder less successful agricultural development, such as: those of nature with the greatest impact are climate changes, which influence changes in cultivation sessions and in the characteristics of productive soils, availability of water for irrigation and animal feed. On the socioeconomic side, it includes the willingness or interest of young people who want to work as farmers, less investment and the impact of the Covid-19 pandemic. It is concluded that natural and socioeconomic impacts can reduce agricultural productivity, so that this will be a major challenge for the development of the agricultural sector in the future.

Plants are a rich source of antibiotics, but screening all the existing plant species for biological activity using current methods can be time and resource consuming. The present study is to investigate whether powdered plant materials would perform as well as plant extracts in the screening of plants with antimicrobial activity. In the new method proposed (STAMP), we compared in vitro antimicrobial activity of powdered plant materials from 12 species against bacteria and fungi. We confirmed these results with their corresponding aqueous (wet) and hydro-alcoholic extracts and one species testing the antimicrobial activity of two isolated compounds. Compared with hydro-alcoholic extracts, screening using the powdered plant materials correctly identified the majority of the species with antimicrobial activity against Candida albicans (sensitivity 91%, specificity 86%), C. parapsilosis (sensitivity 100%, specificity 67%), and Staphylococcus aureus (sensitivity 64%, specificity 86%). For bacteria, the method performed better in a pH of 9.0. The antimicrobial activity of two compounds isolated from one species (maytenin and netzahualcoyone) confirmed the results. In conclusion, the use of powdered plant materials for screening plants with antimicrobial properties is a cheap, widely available, technically easy, time sparing, reproducible, and sensitive method and can significantly shorten the time and money spent during drug development.

Species of the genus Erythrina are frequently used as ornamental plants and in projects to restore degraded areas. Also, extracts from its shoots and stems are popularly used as a herbal medicine with validated activity on the central nervous system. The objective of this study was to evaluate E. mulungu and E. velutina seed germination and seedling development potential aiming commercial scale production of those species. Seeds stored for one or twelve months at 10°C ± 2°C were sown in sand, soil or Plantmax? substrates and evaluated for germination and seedling development. Subsequently, seedlings sprouted in Plantmax? were transferred to polyethylene bags and kept in greenhouse, under direct sunlight for plant development (plant height, stem diameter and root length pivoting) evaluations. Four-month-old plantlets were transplanted to the field and after a period of one year the collar diameter and shoot height (of each plant were measured. Seed germination rates of both species grown in soil and in Plantmax? were significantly high (over 80%). Storing seeds for 1 month did not inhibit germination. However, seeds stored for twelve months had germination reduced by more than a quarter. The development of plants in greenhouse and in the field was satisfactory, indicating the viability of producing E. mulungu and E. velutina on a commercial scale, in order to meet the expanding market demand for herbal medicines.
