title: Evaluation of Collagen Fibers, MMP2, MMP9, 8-OHdG and Apoptosis in the Aorta of Ovariectomized LDL Knockout Mice Submitted to Aerobic Exercise

description: Abstract Background: In menopause, there is greater cellular exposure to oxidative stress, related to the decreased antioxidative effects of estrogen. These metabolic changes favor the progression of cardiovascular diseases, such as atherosclerosis. Abnormal function of the aorta - the most important artery - is associated with many cardiovascular diseases. Collagen, especially types I and III, is one of the most important aortic wall components and it can be affected by many factors, including menopause. The 8-OHdG is one of the main markers of DNA oxidative damage induced by reactive oxygen species (ROS). Objective: We aimed to investigate effects of moderate aerobic training on the ascending aorta of LDL-knockout (LDL-KO) and ovariectomized female mice. Methods: A total of 15 C57BL/6 mice and 15 LDL-KO mice were divided into experimental groups. The thickness and volume density of types I and III collagen fibers were performed by morphoquantitative analysis, whereas the MMP-2 and MMP-9 and 8-OHdG were detected by immunohistochemistry and apoptosis was detected by the TUNEL assay. The significance level for all tests was p &lt; 0.05. Results: Exercise causes an increase in the thickness of the aorta in LDL-KO groups, particularly accentuated in the ovariectomized groups. The type I collagen fibers showed an increase in volume density influenced by training in both Control groups and in the LDL-KO group. Type III collagen density decreased in both groups. The MMP-2 showed moderade immunostaining in the tunica media in LDL-KO groups, which did not occur in the control groups and the MMP-9 stained irregularly in all tissues. The marker 8-OhdG was stronger in the exercise training groups. Additionally, the ovariectomy, the exercise training and the LDL-KO treatments increased apoptosis. Conclusion: These results suggest that moderate-intensity aerobic exercise in ovariectomized mice associated to an increase in LDL rate possibly increases oxidative stress and apoptosis induction.

title: Time dilation, accelerated frames, and the twin paradox

description: Abstract Although the twin paradox is as old as the special theory of relativity itself, understanding of its resolution is often obscured by student's miscarried intuition. That is usually a result of an incomplete understanding of some predictions of the theory or of its range of validity. In this article, we present a didactic solution to the problem aiming at elucidating some understanding gaps. Discussing the precise content of the time dilation predicted by special relativity, we eliminate a first intuition that might suggest the existence of a paradox. Then we show why special relativity alone is enough to solve the problem without any need to invoke the general theory of relativity. We conclude this work presenting a solution to the twin paradox from the point of view of the stationary twin as well as from the traveling twin.

title: Transcultural adaptation to Portuguese of the Mind Excessively Wandering Scale (MEWS) for evaluation of thought activity

description: Abstract Introduction: The concept of mind wandering refers to periods during which attention and content of thoughts depart from the original idea or activity being performed. The phenomenon occurs commonly in the general population and the Mind Wandering Excessively Scale (MEWS) evaluates its frequency, intensity and related negative outcomes. Objective: To describe the cross-cultural adaptation of the MEWS. Methods: Cross-cultural adaptation of the original scale followed five consecutive steps: translation, backtranslation, appreciation of semantic equivalence and administration to a convenience sample to 20 adults with attention deficit hyperactivity disorder (ADHD) and 20 normal controls. Results: Results indicated a satisfactory equivalence between the original and translated versions. A synthesis version for Brazilian Portuguese is presented. Conclusions: MEWS provides information on thought activity, which is particularly important in ADHD cases. The Brazilian Portuguese version would be welcome to address specific treatment responses and obtain new outcome measures

title: Nutritional Evaluation of Soybean Hulls with or without β-Mannanase Supplement on Performance, Intestinal Morphometric and Carcass Yield of Broilers Chickens

description: ABSTRACT The objective was to evaluate the performance, intestinal morphology and carcass yield of broilers fed corn-soybean meal (SBM) diet or corn-SBM-soybean hull (SH) with or without b-mannanase supplementation. Thousand four hundred and forty Cobb Slow-male- chicks were housed design following a factorial scheme 2 x 2 (corn-SBM diet and corn-SBM-SH diet vs with and without b-mannanase), composing 4 treatments and 9 replicates each treatment, with 40 birds each replicate. At 21 days, corn-SBM diet supplemented with b-mannanase resulted in better (p&lt;0.05) feed conversion. At 42 days, the weight gain (p&lt;0.05) and feed intake (p&lt;0.05) of the birds fed diets containing SH was 2.6% and 2.9% higher than that of birds fed corn-SBM diets, respectively, independent of b-mannanase supplementation. Birds supplemented with b-mannanase had a lower length of villi (p&lt;0.05) and absorption area (p&lt;0.05) of jejunum mucosa, and higher (p&lt;0.05) relative liver weight. Diets with SH and without addition of b-mannanase resulted in higher relative liver weight (p&lt;0.05) and lower percentage of fat in the carcass. It was not found statistical differences (p&gt;0.05) in the quality of the poultry litter with the inclusion of the enzyme in the diet. The use of b-mannanase in diets with higher concentration of fiber improves the feed conversion of broilers from 1 to 21 days and can be an important nutritional and economic strategy in situations of unavailability of raw material of better quality. Corn-SBM-SH diet resulted in greater weight gain at 42 days than corn-SBM diet.

title: Neurosyphilis and classical music: the great composers and “The Great Imitator”

description: ABSTRACT Throughout history, neurosyphilis has victimized many people, including classical composers, with a wide range of clinical presentations. Methods: Six articles with descriptions of composers with possible neurosyphilis were reviewed. Results: Neurosyphilis is a possible diagnosis for composers like Beethoven, whose progressive hearing loss influenced his career, culminating in complete deafness. In his autopsy, cochlear nerve atrophy and cochlear inflammation were described. Donizetti developed behavioral changes, as well as headaches, general paresis and seizures. Both Schumann and Wolf suffered from personality changes, persecutory delusions and general paresis. Joplin and Delius also had symptoms attributed to syphilis. Autopsy findings confirmed the diagnosis of Smetana, who developed dementia, deafness and auditory hallucinations with rapid progression. His tinnitus was musically represented in his first String Quartet. Conclusion: Neurosyphilis victimized several notorious composers. It can be argued that neurosyphilis was a major source of inspiration as well, being responsible for the genesis of musical masterpieces.

title: The Effects of Using Garlic Extract for Quail Hatching Egg Disinfection on Hatching Results and Performance

description: ABSTRACT This experiment was carried out to determine the effects of using garlic extract (Allium sativum) as an alternative to formaldehyde for the disinfection of hatching eggs on hatching traits and growth performance of quails. Four treatments, with 240 hatching eggs each, were evaluated: egg immersion in two different levels (2.5% and 5.0%) of garlic extract (garlic-1, garlic-2), formaldehyde fumigation (positive control), and eggs not submitted to disinfection (negative control). Mid-term and late embryomortality, pipped egg, and culled chick rates were not influenced by the (p&gt;0.05). The highest (p&lt;0.05) early embryo mortality rate was detected in the formaldehyde treatment (9.99%), and the lowest in garlic-2 treatment (2.68%). Hatchability of fertile eggs was the lowest in the formaldehyde group (83.78%), followed by the control (85.20%), garlic-1 (87.11%) and garlic-2 (88.72%) groups, respectively. The highest final body weight (5 weeks of age) was obtained in the garlic-2 group (304.1 g), followed by the control (294.13 g), formaldehyde (290.56 g), and garlic-1 (288.44 g), respectively, and the differences were statistically significant (p&lt;0.05). Feed intake and feed conversion ratio were not influenced by the treatments (p&gt;0.05). The results obtained for hatching traits and live performance parameters indicated that the immersion of eggs in garlic extract may be used as an alternative to formaldehyde fumigation for the disinfection of hatching quail eggs.

title: Zootechnical and economical evaluation of the creation of marine shrimp (Litopenaeusvannamei) in different management strategies and densities

description: ABSTRACT The objective of this study was to evaluate the zootechnical and economic viability of shrimp farming with three different management strategies and different densities, 92, 14 and 8 shrimp.m-2 for treatments M1, M2 and M3, respectively, with a maximum cultivation time of 79 days. Survival was reduced in all treatments, probably influenced by the disease of the White Spot and the high salinity of the water of the nurseries, causing reduction in the production and raising the Apparent Food Conversion Factor-FCAA in M1 and M2. The Profitability and Profitability Indices were significantly lower in the M1 treatment when compared to M2 and M3. The cultivation with high initial population (M1) caused economic and zootechnical losses due to high FCAAs, reduced individual biomass and high total operational costs-TOC, making this treatment unfeasible. The internal rates of return for M2 and M3 were attractive, generating profit and a positive balance for the net present value. Monoculture of shrimp with small populations and submitted to Mancha Branca (M2 and M3), managed to guarantee the return of invested capital. This return only occurred due to the high prices practiced in 2016, otherwise, lower prices per kilo of shrimp would make the activity economically unfeasible.

title: White matter volume is decreased in bipolar disorder at early and late stages

description: Abstract Introduction: Bipolar disorder (BD) is a debilitating mood condition that affects approximately 1.3% of people worldwide, although some studies report up to 3.9% lifetime prevalence and 4-6% in adults when broad diagnostic criteria are applied. Objective: To compare differences in total white matter (WM), corpus callosum (CC) and total gray matter (GM) volumes in patients with type I BD at early and late stages compared with controls. Methods: Fifty-five subjects were enrolled in this study protocol. The double case-control design included 14 patients with BD at early stage; 15 patients at late stage; and their respective matched controls (14 and 12 subjects). Results: CC and total WM volumes were significantly smaller in patients with BD at early and late stages vs. controls. There was no difference for total GM volume in the early stage group, but in patients at late stage total GM volume was significantly smaller than in controls. The total GM volume reduction in patients at late stage is in agreement with the neuroprogression theory of BD. The reduction of WM volumes in total WM and in the CC at early and late stages supports the possibility that an early demyelination process could occur underlying the clinical manifestation of BD. Conclusion: Our findings may direct to the investigation of WM abnormalities in populations at high risk to develop BD, perhaps as early biomarkers before the overt syndrome.

title: Effect of Dietary Lysine Regimens on Growth Performance and Meat Composition in Aseel Chicken

description: ABSTRACT A study was designed with the objective, to evaluate the effect of dietary lysine (Lys) regimens on growth performance and meat composition of Aseel chicken. In total, 540 day old chicks, 180 from each variety, were randomly assigned to 9 experimental groups in a 3 (Varieties: Mianwali (MW), Peshawari (PW), and Lakha (LK)) × 3 (Lys regimens: L1, L2 and L3:1.35, 1.30 and 1.25%) factorial arrangement under randomized complete block design (RCBD) with sex as block. Each experimental group was replicated 6 times with 10 birds in each with average weight of 29 gram. Feed intake (FI), weight gain (WG) and feed:gain ratio (F:G) parameters of growth performance and Dry Matter (DM), Ash, Crude Protein (CP) and Ether Extract (EE) parameters of meat composition were evaluated. The results indicated better (p=0.0006) WG and (p=0.0006) F:G was observed in MW verities. Among different Lys regimens, higher and medium level in the diet improved WG (p

title: LOSS OF WATER AND NUTRIENTS IN DIFFERENT SOIL TILLAGE SYSTEMS SUBJECTED TO NATURAL RAINFALL IN THE STATE OF MATO GROSSO, BRAZIL

description: ABSTRACT The aim of this study was to evaluate the loss of water and nutrients by laminar runoff in different soil tillage systems subjected to natural rainfall. Five experimental plots were established for the cultivation of cotton in the city of Campo Verde - MT, with the following treatments: CTDP = conventional soil tillage and planting of the cotton in the direction of the slope; CTCP = conventional tillage and contour planting; CP = tillage of soil with a disk harrow and a leveling harrow, followed by contour planting; CoP = tillage by two passes of a leveling harrow followed by contour planting; MTCP = minimum tillage with contour planting. The losses of water by laminar runoff in were determined by the stored volume and samples were taken to quantify nutrient losses in water (nitrite, nitrate, phosphate and potassium). The losses of water by runoff were highest for the CTDP; intermediate for the treatments CTCP, CoP and MTCP, and lowest for the CP. Potassium (K) was the nutrient that had the highest concentrations and losses in water: the highest values were found in the CTDP and CTCP tillage systems, whereas the lowest were observed for the CP, CoP, and MTCP treatments. The concentrations and the losses by water erosion of phosphate (PO43-), nitrite (NO2–), and nitrate (NO3–) were low in all of the soil tillage systems compared to the losses of K in this study.
