25. Maternal administration of cannabidiol promotes an anti-inflammatory effect on the intestinal wall in a gastroschisis rat model
Gastroschisis (GS) is an abdominal wall defect that results in histological and morphological changes leading to intestinal motility perturbation and impaired absorption of nutrients. Due to its anti-inflammatory, antioxidant, and neuroprotective effects, cannabidiol (CBD) has been used as a therapeutic agent in many diseases. Our aim was to test the effect

26. Synthesis and Expansion of Bicyclic Enol Ether: A Probable Precursor for the Synthesis of Macrolide (±)-Pyrenophorin
A convenient procedure for the synthesis and expansion of bicyclic rings has been developed for the production of probable precursors of non-racemic pyrenophorin, an antibiotic dilactone. The major highlight for this new synthetic methodology came from the use of a readily available reagent of easy manipulation, 9-oxabicyclo[3.3.1]nonane-2,6-diol, for the pr

27. Preservative effects of rosemary extract (Rosmarinus officinalis L.) on quality and storage stability of chicken meat patties
Abstract The effect of different level of rosemary extract (RE) (Rosmarinus officinalis Linn.) cultivated in Jordan, and other preservative on quality and stability of ground chicken meat was investigated. Treatments, were involved 1) Control (No additive), 2) 300 ppm (RE), 3) 350 ppm RE, 4) 300 ppm L-Ascorbic acid (E-300), 5) 200 ppm Sodium nitrite (E-250),

28. Effect of direct adding oregano essential oil (Origanum syriacum L.) on quality and stability of chicken meat patties
Abstract Evaluate of Origanum syriacum L. essential oil grown in Jordan, and other comparable antioxidant on TBARS, total carbonyl, color values, and sensory attributes of raw chicken meat was investigated. Six treatments were prepared: (1) control (no additive); (2) 100 ppm oregano essential oil (OE); (3) 150 ppm OE; (4) 300 ppm L-ascorbic acid (E-300); (5)

29. Methylene Violet 3 RAX Dye as a New Reagent for the Determination of Nitrite in Cured Meats and Vegetables
In this contribution we propose, for the first time, the use of Methylene Violet 3 RAX dye for the detection and determination of nitrite in cured meats and vegetables. Quantification is based on the decrease in absorbance of the dye, which is proportional to the nitrite concentration. The proposed method presents linear response (r > 0.99) in the range from

30. Determination of phenolic profile by HPLC-ESI-MS/MS and anti-inflammatory activity of crude hydroalcoholic extract and ethyl acetate fraction from leaves of Eugenia brasiliensis
ABSTRACT Eugenia brasiliensis Lam., Myrtaceae, is used in folk medicine for anti-inflammatory diseases such as arthritis and rheumatism. This study investigated the anti-inflammatory activity and phenolic profile of the crude hydroalcoholic extract and ethyl acetate fraction from E. brasiliensis leaves. Crude hydroalcoholic extract and the ethyl acetate frac

31. Mitochondria-rich cells changes induced by nitrite exposure in tambaqui (Colossoma macropomum Cuvier, 1818)
ABSTRACT The gill mitochondria-rich cells of the juvenile Amazonian fish Colossoma macropomum were analyzed using light and scanning and transmission electron microscopy after 96 h exposure to 0.04 and 0.2 mM nitrite. Although the number of mitochondria-rich cells decreased significantly in the lamellar epithelium, no decrease was found in the interlamellar

32. Aerobic Swim Training Restores Aortic Endothelial Function by Decreasing Superoxide Levels in Spontaneously Hypertensive Rats
OBJECTIVE: We aimed to determine whether aerobic training decreases superoxide levels, increases nitric oxide levels, and improves endothelium-dependent vasodilation in the aortas of spontaneously hypertensive rats. METHODS: Spontaneously hypertensive rats (SHR) and Wistar Kyoto rats (WKY) were distributed into 2 groups: sedentary (SHRsd and WKYsd, n=10 ea

33. STABILITY OF PARTIAL NITRITATION OF POULTRY SLAUGHTERHOUSE WASTEWATER IN A SEQUENTIAL BATCH REACTOR
ABSTRACT The aim of this study was to monitor the stabilization of a sequential batch reactor (SBR) regarding the partial nitritation of poultry slaughterhouse wastewater, aiming at preparing it for a reactor with bacteria that promote anaerobic ammonia oxidation (anammox). A cylindrical reactor with a useful volume of 3.5 L, mechanical agitation (50 rpm), a

34. Oxidative Stress in Human Aorta of Patients with Advanced Aortoiliac Occlusive Disease
Abstract Introduction: Oxidative stress seems to be a role in the atherosclerosis process, but research in human beings is scarce. Objective: To evaluate the role of oxidative stress on human aortas of patients submitted to surgical treatment for advanced aortoiliac occlusive disease. Methods: Twenty-six patients were divided into three groups: control gr

35. Association of swine wastewater and mineral fertilization on black oat production
ABSTRACT Swine wastewater (SW) has high organic load, becoming an important source of macro and micronutrients to plants, promoting the improvement of soil quality and development in various cultures. However, when done without agronomic and environmental criteria, it can cause soil problems, nutrient leaching, water resource damage and plant toxicity. The o

36. Oxidative stress in carotid arteries of patients submitted to carotid endarterectomy. The role of aging process
ABSTRACT PURPOSE: To evaluated the role of oxidative stress on aging process in patients submitted to carotid endarterectomy. METHODS: Twenty patients were divided into two groups: older group (≥ 70 years old); and the younger group (< 70 years old). We evaluated the reactive oxygen species (ROS) concentration, nicotinamide adenine dinucleotide phospha
