title: QUALITY OF ACEROLA (Malpighia emarginata) TREATED WITH GIBBERELIC ACID AND STORED UNDER REFRIGERATION

description: ABSTRACT The goal of this study was study the postharvest quality of acerola clone BRS 236 (Malpighia emarginata D.C.) which was harvested at physiological maturity and submitted to four treatments under immersion during 5 minutes at 25 °C, which are: control (water), 60 mg L-1; 120 mg L-1 and 180 mg L-1. After treatment the fruits were packed in polystyrene trays and placed with polyethylene film and then stored at 10 ± 2 °C and 85 ± 5% RH for 12 days. Were analyzed in three days intervals (0, 3, 6, 9 and 12 days): skin color, firmness, pH, titratable acidity, soluble solids, SS/TA ratio, vitamin C and yellow flavonoids. Vitamin C, anthocyanins and yellow flavonoids were not influenced by treatments with GA3 at the end of 12-day of cold storage at 10 ºC. The exogenous application of 120 mg L-1 of GA3 resulted in retention of red color and content of anthocyanins of acerola fruits BRS 236 clone 12-day storage at 10 °C.

title: The therapeutic challenge of giant splenic artery aneurysm: a case repport

description: ABSTRACT Giant splenic artery aneurysm is a rare condition that represents an eminent life threatening for the patient, requiring, therefore, urgent surgical correction. A 61-year-old woman, former smoker, hypertensive, hypercholesterolemic and multipara sought our service because of a large tumor in the mesogastrium, which was an abdominal ultrasound finding. Despite the size of the tumor, the patient was asymptomatic. The angiotomography and the magnetic resonance image of the abdomen were suggestive of giant splenic artery aneurysm with more than 10cm in diameter that was confirmed by an angiography. She underwent surgery, open splenectomy, and partial aneurysmectomy. The approach of the celiac artery, which was ligated, was only possible with medialvisceral rotation because there was no possibility to view it through the anterior access. The histopathological test of aneurysmatic wall revealed atheroma plaques in the intima. The patient progressed without complications and she was discharged cured. In general, giant splenic artery aneurysms are symptomatic, however, as in the case we report, it may be asymptomatic and found in abdominal imaging exam. Although less invasive Interventional methods exist, such as laparoscopy and endovascular techniques, they were considered inappropriate in this case. Conventional open surgery should be the therapy of choice for a giant splenic artery aneurysm.

title: RATE-PRESSURE PRODUCT AND VARIATION OF HEART RATE AFTER ISOKINETIC EFFORT IN ADULTS AND ELDERLY

description: ABSTRACT Introduction: Aging predisposes to multisystem changes, for example, in the cardiovascular and musculoskeletal systems. The practice of physical exercise is an important therapeutic resource to delay losses of organic functions. However, there is little knowledge about cardiovascular responses during and after isokinetic exercise in the elderly. Objective: The objective of this study is to analyze the responses of heart rate, blood pressure, and rate-pressure product in individuals of different age groups submitted to isokinetic muscular effort. Method: The study consisted of 60 volunteers distributed into three age groups - G1: 30-45 years, G2: 45-60 years, and G3: 60-75 years - submitted to bilateral flexion-extension knee test in isokinetic dynamometer with angular velocity of 60°/second to verify hemodynamic responses. Data were analyzed using the Bioestat® 5.3 software, by the Kruskal-Wallis test followed by Dunn’s test for independent samples and Friedman’s test for dependent samples, as well as comparing the Kaplan-Meier curves by means of log-rank test, considering P≤0.05. Results: The elderly group (G3) presented higher values of systolic blood pressure, rate-pressure product, and time to return to baseline heart rate compared to the younger group (G1). Conclusion: The 60-75 year old group had higher myocardial oxygen consumption during and after the exercise, as well as longer time to return to baseline HR compared with younger patients.

title: TRANSITION POINTS OF HEART RATE AT RACE WALKING

description: ABSTRACT Introduction: Heart rate provides useful information for race walking training. Objective: The objective of study was to analyze the behavior of heart rate (HR) and inflection points (HRIP) and deflection points (HRDP) in a progressive test of race walking (PTRW) before and after 20 training sessions. Methods: Participants were 13 young athletes (12.46 ± 1.61 years, 44.29 ± 10.25 kg, 157.93 ± 12.03 cm, 24.39 ± 7.60 F%). The PTRW was held at an official athletics track before and after training. The HR data and load were plotted every minute to identify the HRIP and HRDP. Results: The HR showed sigmoid behavior with the identification of transition points (TP), being in the pre-training: a) eight subjects HRIP (5.31 km·h-1; 125 bpm)and HRDP (7.63 km·h-1; 169 bpm); b) one subject only HRIP (7.00 km·h-1; 149 bpm); c) one subject only HRDP (8,00 km·h-1; 170 bpm); d) three subjects had no TP observed, and post-training: a) 12 subjects HRIP (5.46 km·h-1; 125 bpm) and HRDP (7.75 km·h-1; 168 bpm); b) one subject HRDP (7.50 km·h-1; 184 bpm). The HRIP was found to be significantly lower than the HRDP in pre-training (p&lt;0.001) and post-training (p&lt;0.001). When we compared HRIP and HRDP in the pre- and post-training we found no significant difference either in relation to the load (p=0.87 and p=0.61) or HR (p=0.60 and p=0.99). Conclusion: It is concluded that the HR has curvilinear relation with the load, and that it is possible to detect its transition points during PTRW.

title: ECONOMIC INJURY LEVEL OF CITRUS BLACK-FLY IN COMMERCIAL ‘PERA-RIO’ ORANGE AREA

description: ABSTRACT Citrus black-fly (Aleurocanthus woglumi) has become an important pest in many citrus-producing regions in Brazil, causing direct and indirect damage to plants. Due to the lack of studies on the economic injury level (EIL) for this insect, control efficiency can be impaired. The objective of this research was to determine the EIL and the influence on the productivity of orange trees colonized by A. woglumi nymphs in an orchard located in the municipality of Capitao-Poço, Pará, using statistical analysis and damage prediction models through multivariate statistics. Population levels varied along the experiment. Infestation by A. woglumi nymphs negatively influenced orange production in Capitao-Poço with the highest population densities of the pest associated to lower plant productivity. The level of A. woglumi infestation on orange trees resulting in economic losses was, on average, 47.63% of infested plants, ranging from 22.75 to 89.92% and EIL is expressed by equation Y = 97.39 – 8.43x.

title: Spatial risk of tuberculosis mortality and social vulnerability in Northeast Brazil

description: Abstract INTRODUCTION: Tuberculosis (TB) is the most common infectious disease in the world. We aimed to analyze the spatial risk of tuberculosis mortality and to verify associations in high-risk areas with social vulnerability. METHODS: This was an ecological study. The scan statistic was used to detect areas at risk, and the Bivariate Moran Index was used to verify relationships between variables. RESULTS: High-risk areas of tuberculosis mortality were statistically significantly associated with domain 2 of the Social Vulnerability Index (I=0.010; p=0.001). CONCLUSIONS: This study provides evidence regarding areas with high risk and that vulnerability is a determinant of TB mortality.

title: BTEX removal by fungi in continuous flow aerobic reactor

description: ABSTRACT The removal of benzene, toluene, ethylbenzene and xylene (BTEX) compounds by Aspergillus niger AN 400 was studied in a continuous flow reactor which was operated at hydraulic retention time (HRT) of 12 hours evaluate the efficiency of the system in the bioremediation of water polluted with gasoline in the presence (Step 1) and absence (Step 2) of 0.5 g.L-1 glucose. In the first step it was also studied the influence of the addition of nutrients in the influent on the efficiency of the process. The addition of nutrients was beneficial to the process and, with the removal of glucose, the efficiency was maintained due to the use of ethanol - which is a Brazilian gasoline constituent (25%) - and was used as co-substrate. Both ethanol and glucose are more easily assimilated carbon and energy sources for fungi and were used as co-substrate in the degradation of BTEX. Thus, in Step 2, when only ethanol was in the biomedia, averages percentage of 88% for benzene, 90% in toluene, 90% ethylbenzene and 91% for meta, para and ortho-xylene (m, p and o-xylene) were reached, with the formation of phenolic by-products in between. The fungal population in the middle prevailed throughout the operation of the reactor.

title: CORRELATION AMONG DAMAGES CAUSED BY YELLOW BEETLE, CLIMATOLOGICAL ELEMENTS AND PRODUCTION OF GUAVA ACCESSES GROWN IN ORGANIC SYSTEM

description: ABSTRACT The objective of this research was evaluate the damage caused by the yellow beetle on 85 guava accessions and correlations of the damage with the climatological elements and the production of fruit in an orchard of guava conducted in organic system. Ten leaves by access were analyzed containing the injury of insect attack. Each leaf had its foliar area measured by leaf area meter and, after obtaining the total area, the leaf was covered with duct tape, and measure again. The averages were compared by Scott-Knott test at 5% probability. The 15 accessions with highest average damage had the data submitted to the correlation with the minimum and maximum temperature, precipitation and relative humidity. The production was obtained by the number of fruits/plant. The damages are negatively correlated with the mean relative humidity of 7:00h (local time) in the period of 14 days prior to the assessments, and negatively affect production. The accessions Saito, L4P16, Monte Alto Comum 1 and L5P19 are promising in organic agriculture, for presenting good production and minor damage to insect attack, when compared to others.

title: Lipophilicity Study of 1-(Benzofuran-2-yl)ethan-1-one Oxime and its Substituted O-Benzyl Ethers

description: Heterocyclic oxime ethers play a significant role in organisms due to their biological activity. Lipophilicity is an important parameter that may affect biological activity of the compounds 1-(benzofuran-2-yl)ethan-1-one oxime and its nine biologically active ethers. The relationship between the structure and lipophilicity parameters (log kw values) of the ten compounds is here described. Reversed phase high performance liquid chromatography (RP-HPLC) method was used having methanol, 2-propanol and acetonitrile as organic modifiers of the mobile phases. Both experimental (log kw) and calculated (log P) parameters showed to be strongly positively correlated. The weakest correlation with all the data was for the log kw methanol. For all of analyzed compounds, log kw values are smaller than 5 (except for analyses carried out in methanol), and this result corresponds to the Lipinski’s rule in the range of lipophilicity. Therefore, in the case of their use as drugs, they will be probably active after oral application.
