title: Morpho-anatomical effects of sodium azide and nitrous acid on Citrullus lanatus (Thunb.) Matsum. & Nakai (Cucurbitaceae) and Moringa oleifera Lam. (Moringaceae)

description: ABSTRACT Chemical mutagens (e.g. sodium azide and nitrous acid) are important tools in crop improvements because they produce resistance against pathogens in crops to improve their yield and quality traits. This study investigates the morphological and anatomical effects of sodium azide and nitrous acid on Citrullus lanatus and Moringa olefeira at various concentrations (1 mM, 2 mM, 3 mM and 4 mM) for 4 hours, and planted in plastic pots for 12 weeks observations. Results showed that sodium azide and nitrous acid have differential influenced on morphological features (stem height, leaf number and root length) in C. lanatus and M. olefeira respectively. Anatomical features (stomatal density, index and size) are more influenced by the sodium azide-treated plants in both plants than in the nitrous acid-treated plants. Both mutagens are more effective in the two plants than the control.

title: Effects of Low-Protein Diet on lipid and anthropometric profiles of patients with chronic kidney disease on conservative management

description: ABSTRACT Introduction: Chronic Kidney disease (CKD) patients have a high prevalence of cardiovascular mortality, and among the risk factors are dyslipidemia and obesity, common findings in the early stages of CKD. The aim of this study was to evaluate the effects of low protein diet (LPD) on the lipid and anthropometric profile in non-dialysis CKD patients. Methods: Forty CKD patients were studied (20 men, 62.7 ± 15.2 years, glomerular filtration rate (GFR) 26.16 ± 9.4 mL/min/1.73m2). LPD (0.6g/kg/d) was prescribed for six months and, biochemical and anthropometric parameters like body mass index (BMI), waist circumference and body fat mass (assessed by dual X-ray absorptiometry - DXA) were evaluated before and after six months with LPD. Results: After six months of nutritional intervention, patients presented reduction on BMI (from 28.1 ± 5.6 to 27.0 ± 5.3 Kg/m2, p = 0.001), total cholesterol (from 199.7 ± 57.1 to 176.0 ± 43.6mg/dL, p = 0.0001), LDL (from 116.2 ± 48.1 to 97.4 ± 39.1 mg/dL, p = 0,001) and uric acid (from 6.8 ± 1.4 to 6.2 ± 1.3 mg/dL, p = 0.004). In addition, GFR values were increased from 26.2 ± 9.5 to 28.9 ± 12.7mL/min (p = 0.02). The energy, proteins, cholesterol and fiber intake were reduced significantly. Conclusion: LPD prescribe to non-dialysis CKD patients for six months was able to improve some cardiovascular risk factors as overweight and plasma lipid profile, suggesting that LPD can be also an important tool for protection against cardiovascular diseases in these patients.

title: Preservative solutions on quality and biochemical aspects of calla lily flowers

description: ABSTRACT The knowledge of physiological and biochemical aspects occurring at the postharvest phase of flowers is critical to guide efficient conservation techniques for maintaining quality and longevity. Factors that cause deterioration of cut flowers after harvest are dehydration, low carbohydrate contents, the presence of microorganisms in vase solution or stem and late stage of development at harvest. Thus, the objective was to determine the effect of harvest stages of calla lily stems and storage solutions on water relations and contents of starch and sugars. Flower stems were harvested in the following opening stages of the spathe: early-stage (cartridge) and 1/3 open and were arranged in six storage solutions containing 1, 2, 4 and 6% glucose and the controls with water and solution with 5% sucrose. Results indicate that at early-stage and 1/3 open harvesting stages, the addition of glucose at concentrations of 4% and 6% stimulated flower opening. Calla lily flower stems maintained in water and in solution with 1% glucose had lower percentages of fresh weight loss and better maintenance of water balance, with a small reduction in the contents of starch and soluble sugars. The addition of sugars in the storage solution was efficient in opening early-harvested stems. Harvest the floral stems in initial stages allow the maintenance of the commercial quality for longer period, without pollen production. The use of water relations allowed the determination of the better sugar concentration for the conservation of open-harvest of floral stems.

title: New records of red seaweeds to the coast of Ceará State, northeastern Brazil

description: ABSTRACT A recent floristic survey of Rhodophyta from Ceará State, Brazil (02º46'30''-07º52'15''S and 37º14'54''-41º24'45''W), revealed the occurrence of 113 species distributed into 14 orders, 28 families and 63 genera. Of these, 18 species belonging to seven orders are new records; some of them poorly described and illustrated in the literature or cited only checklists. Therefore, aiming to expand the taxonomic knowledge about these poorly known species, we present detailed descriptions, illustrations, and comments on related taxa. The occurrence of Ceratodictyon scoparium is confirmed for the South Atlantic coast. The male gametophytes of Dohrniella antillarum var. brasiliensis and tetrasporophytes of Gracilariopsis silvana are illustrated for the first time. Ceramium fujianum is a new addition to northeastern Brazil. Among the new records, Callithamnion corymbosum, Ceramium clarionense, C. fujianum and C. scoparium showed a significant expansion of their geographic distribution along the Brazilian coast. Most of the newly recorded species are filamentous, small-sized or tufted algae, highlighting the need for new collections to detect the presence of these components.

title: Evaluation of short-term prognostic factors of ranibizumab in patients with dabetic macular edema

description: Abstract Purpose: Study the prognostic factors for short-term visual improvement in pacients treated with ranibizumab (IVR) for diabetic macular edema (DME). Methods: cross-sectional descriptive study in which 41 eletronic medical records of patients who attended in a private medical clinic in Belo Horizonte - Minas Gerais in a period of August / 2016 to May / 2017. It was verified general data and previous history of patients who received consecutive monthly IVR for DME, analyzing sex, age and presence of previous treatment as possible prognostic factors determining the changes in visual acuity measured by the Snellen table after the monthly procedure. Results: In the total sample, 51.2% were female subjects. The mean age was 64.20 ± 7.54 years. Age, previous treatment and gender were not correlated with better visual acuity in any time. Conclusion: The major strategy of DME treatment nowadays is intravitreal injections, which have proved to be an effetive way of visual acuity improvement. However, many patients do not exhibit the expected outcome or are refractory to treatment. Aiming to predict the treatment efficacy in short term - also to provide the patient a reasonable expectation about the outcome - based on prognostic factors, new clinical studies are necessary since there are so few that approach this subject - such an important treatment of a very prevalent disease.

title: AORTIC POST-RESISTANCE EXERCISE HYPOTENSION IN PATIENTS WITH PERIPHERAL ARTERY DISEASE

description: ABSTRACT Introduction: A single session of resistance training decreases brachial blood pressure (BP) in patients with peripheral artery disease (PAD). However, it is not known whether similar responses occur in aortic BP, which is a better predictor of cardiovascular risk. Objective: This study aimed to analyze the effects of a single session of resistance training on aortic BP in PAD patients. Methods: This randomized, crossover, controlled trial involved 16 patients. All of them performed a session of resistance training (R - 3 x 10 reps in eight exercises, 5-7 on the OMNI Scale) and a control session (C - resting for 50 min). Before and after each session, aortic BP was assessed by applanation tonometry technique. Results: There was an increase in systolic (P&lt;0.002) and mean (P&lt;0.001) aortic BP in both sessions; however, higher increases were observed in C session (P&lt;0.001). Additionally, diastolic aortic BP only increased after C session (P=0.004). The hypotensive effect of the exercise on systolic, diastolic, and mean aortic BP were -12±2, -6±2, and -7±2 mmHg, respectively. Conclusion: A single session of resistance training promoted a hypotensive effect on aortic BP of patients with PAD, indicating an acute reduction in cardiovascular risk in this population. Level of Evidence I; Therapeutic studies - Investigating the results of treatment.

title: Characterization and chromosomal mapping of the DgmarMITE transposon in populations of Dichotomius (Luederwaldtinia) sericeus species complex (Coleoptera: Scarabaeidae)

description: Abstract Transposable elements are dispersed repetitive DNA sequences that can move within the genome and are related to genome and chromosome evolution, adaptation, and speciation. The aim of this study was to characterize and determine the chromosomal location and accumulation of a Mariner-like element in populations of four phylogenetically related species of the Dichotomius (Luederwaldtinia) sericeus complex. Mapping of the isolated element was performed by fluorescent in situ hybridization in different populations of analyzed species. Characterization of the isolated element revealed a degenerated transposon, named DgmarMITE. This transposon is 496-bp-long, AT rich (57%), and contains 24 bp terminal inverted repeats. In situ mapping revealed presence of this element only in two out of four species analyzed. DgmarMITE sites were located in heterochromatic and euchromatic regions and varied in location and number on the karyotypes of Dichotomius (L.) gilletti and D. (L.) guaribensis across different populations. These results demonstrate differential accumulation of the DgmarMITE in genomes of these species, which is probably due to the occurrence of ectopic recombination and cross-mobilization of the element mediated by the transposase of closely related or unrelated transposable elements.

title: RELATIONSHIP BETWEEN PHYSICAL ACTIVITY, PHYSICAL FITNESS AND CARDIOVASCULAR RISK: STUDY IN MUZAMBINHO, MINAS GERAIS

description: ABSTRACT Introduction: The negative relationship between physical activity, physical fitness, and cardiovascular risk is well established in populations with low levels of physical activity. Objective: The present study investigated this relationship in adults from Muzambinho, Minas Gerais, a population with a high rate of physically active individuals. Methods: Two hundred and thirty-seven individuals (132 women), mostly young adults (44.3% between 20 and 39 years) were assessed. Cardiovascular risk predictors (body mass index, waist circumference, fasting blood glucose, fasting cholesterol, and systolic and diastolic blood pressure), physical activity (total weekly volume of total physical activity) and physical fitness (aerobic fitness and relative hand strength) were measured. Results: More than 90% of the individuals were classified as active (they practiced physical activity for more than 150 min/week). Linear regression identified a negative association of relative hand strength and aerobic fitness to body mass index and waist circumference, as well as a positive association of relative hand strength with diastolic blood pressure. The indicators of physical activity and physical fitness showed no association with global cardiovascular risk. Conclusion: In this population, the inverse relationship between physical activity, physical fitness and cardiovascular risk was limited to physical fitness and obesity indicators, suggesting that in populations with high rates of physically active individuals, the increase in physical fitness, but not in physical activity, can help reduce obesity. Level of Evidence II; Lesser quality RCT.
