Osteochondral (OC) lesions are characterized by defects in two different zones, the cartilage region and subchondral bone region. These lesions are frequently associated with mechanical instability, as well as osteoarthritic degenerative changes in the knee. The lack of spontaneous healing and the drawbacks of the current treatments have increased the attention from the scientific community to this issue. Different tissue engineering approaches have been attempted using different polymers and different scaffolds’ processing. However, the current conventional techniques do not allow the full control over scaffold fabrication, and in this type of approaches, the tuning ability is the key to success in tissue regeneration. In this sense, the researchers have placed their efforts in the development of solid free-form (SFF) techniques. These techniques allow tuning different properties at the micro–macro scale, creating scaffolds with appropriate features for OC tissue engineering. In this review, it is discussed the current SFF techniques used in OC tissue engineering and presented their promising results and current challenges.

CONTEXT: Adenocarcinoma already comprises half the cases of lung cancer. Its insidious clinical evolution contributes to the fact that, in absolute numbers, lung tumor is the cancer with the highest mortality in the world. When still in situ, the adenocarcinoma is even quieter, making its typical presentation on the computerized tomography of an irregular semisolid nodule smaller than 3.0 cm. It is often diagnosed in a finding of examination in an asymptomatic patient. The prevalence of in situ adenocarcinoma (ISA) is less than 5% of pulmonary malignancies and its radiological presentation with a diffuse mosaic paving pattern is even more unusual, mimicking other conditions more frequent to this finding. CASE REPORT: We describe the case of a 44-year-old male patient with a history of chronic smoking admitted to the emergency room at a referral hospital in S?o Paulo on 12/16/2016 with a complaint of progressive dyspnea associated with dry cough for 3 months, intermittent fever and weight loss of 8 kg in 2 months. A chest X-ray and computed tomography showed discrete focal points of peribroncovascular consolidation, predominantly central, areas with frosted glass attenuation associated with smooth thickening of the interlobular septa, sometimes interspersed with areas of preserved parenchyma, giving an aspect of “crazing paving” with diffuse distribution by the pulmonary parenchyma. The patient underwent a biopsy with the anatomicopathological diagnosis of primary Adenocarcinoma in situ of the lung. CONCLUSION: We emphasize that the “crazing paving” of adenocarcinoma in situ pulmonary should be considered and known by the radiologist, because although isolated it is a rare condition, its early distrust in cases of atypical evolution of the most common injuries can avoid a diagnosis in phases more advanced and higher mortality.

The objective of this work was to verify the responses in agronomic and physiological characters of lettuce seedlings when submitted to different doses of humic acids and the presence or absence of inoculation of the bacterium Azospirillum brasilense. The experiment was carried out at the Protected Cultivation Station and Biological Control Teacher Mário César Lopes, belonging to the Experimental Stations Nucleus of the State University of the West of Paraná. The experimental design was a randomized block design, in a 5 × 2 factorial scheme, with four repetitions, totaling 40 plots. The first factor consisted of five solutions containing humic acid (100%, 75%, 50%, 25% and 0%) and the second factor was the presence or absence of the diazotrophic bacterium Azospirillum brasilense obtained by commercial product. Germination tests were carried out in addition to the determination of agronomic characters such as the number of fully expanded leaves, plant height, stem diameter, main root length, shoot dry mass, root dry mass, total dry mass, and Dickson quality index. The association of diazotrophic bacteria and humic acids did not influence the emergency rate, mean emergence time, mean speed of emergency, emergence speed index, plant height, and root length of lettuce seedlings. The dilutions of humic acids, regardless of inoculation with bacteria diazotrophic favored the development of the number of leaves, stem diameter and Dickson quality index. Inoculation of lettuce seeds with diazotrophic bacteria associated with the addition of humic acids, favored the development of the dry mass of root and total dry matter.

Vinasse is the main residue generated during alcohol, sugar and blue rum production by fermentation process. This residue is effluent that could cause serious environmental pollution due to high organic load when is not treated adequately. The aim of this work consists of evaluating the efficiency and application of heterogeneous photocatalysis with TiO2, followed by a biological treatment (activated sludge system) to reduce organic load in the referred effluent. Complete factorial designs indicated the best experimental conditions subsequent to photacatalytic and biological treatments providing a reduction of non-purgeable organic carbon (NPOC) as a variable response. After the photocatalytic process, the sample from the best experiment condition was treated by a biological process in order to verify the degradation efficiency of the effluent organic matter studied according to the hybrid system (Advanced Oxidation Process—Acti- vated Sludge System). This system, which presented more efficiency, had a photochemical treatment of 180 minutes carried out in aerated solutions, pH 9 and effluent in natura, while the biological treatment was performed at pH 8 and sludge concentration of 5 gL–1. The reduction of biochemical oxygen demand (BOD) was >80%.

To evaluate the inclusion of common beans in the diet of cattle in feedlot on characteristics of productive performance, nutrient digestibility and ruminal fermentation parameters, 15 bulls crossed were used in a completely randomized design. The animals were confined for 64 days, and 21 days of adaptation. We evaluated the inclusion common beans at levels of 0%, 13% and 26%. All diets were isocaloric and isonitrogenous with a 45:55 forage: concentrate ratio. The addition of beans in the diet did not affect animal performance, dry matter intake and feed efficiency. Inclusion bean changed the nutrient digestibility of DM, CP, EE, TC and OM, where the best digestibility was observed with the inclusion 13% and the lowest concentration of ruminal NH3-N. The general behavior of ruminal pH in relation to levels of inclusion of beans was 6.2. The inclusion of up to 13% of beans in the diet of feedlot cattle did not alter the apparent digestibility, ruminal and animal performance.

In carbon global cycle, the relationship between the terrestrial ecosystem and the atmosphere where there are, among others, gases that contribute to the greenhouse effect, has become object of relevant scientific interest. The content of organic matter in soil, expressed by its supplies as well as the organic matter degree of stability, are factors that can prevent the soil from acting as a drain and at the same time contribute for it to become a source of those gases. The variations in the way land is used in Brazil are factors responsible for the increase in emission of greenhouse effect gases. Based on these facts, this study was aimed to evaluate the CO2 and CH4 efflux using a gas retention chamber, and to associate these emissions to the organic carbon content in the soil. Two different areas were selected for the study, one in Tijuca Forest National Park, in a forest area, and the other at the Rio de Janeiro Federal Rural University campus. In the latter, the area was stratified in three sub areas according to the vegetation, use and water saturation degree. Samplings were performed during 8 months between 2013 and 2014.

The present study was carried out to evaluate the survival rate of four tropical legume seeds submitted to different periods of ruminal incubation simulated by in vitro and in situ fermentation. The species studied were butterfly pea, stylosanthes, archer and perennial soybean. Four Holstein dairy cows fistulated in rumen were used in the in situ stage. A completely randomized design was used, in a 4 × 6 factorial arrangement (four species, six treatment periods) in the in vitro stage, with four repetitions. A completely randomized block design, arranged in a 4 × 6 factorial scheme (four species × six incubation periods), was used in the in situ stage, with four repetitions. The seeds (50 units of only one species at each repetition) were placed in erlenmeyer flask (250 mL) and were put in a 10 × 15 cm nylon bag in the in vitro stage. The times of incubation were: 6, 12, 24, 48, 96 and 144 hours and the time zero was estimated in the laboratory. The results demonstrate that, when submitted to ruminal incubation, due to their hard and impermeable teguments, legume seeds presented high resistance potential, and, thus, greater chances of germinating after passage through the gastrointestinal tract of bovines, when defecated in pastures. However, stylosanthes are not recommended for insertion in bovine feeding for this purpose, because they do not resist ruminal digestion.
