Borja, M.S.,Oliveira, R.L.,Ribeiro, C.V.D.M.,Bagaldo, A.R.,Carvalho, G.G.P.,Silva, T.M.,Lima, L.S.,Barbosa, L.P. Asian Australasian Association of Animal Productio 2010 Animal Bioscience Vol.23 No.11
The objectives of this study were to determine the highest inclusion of licury (Syagrus coronate) cake in the diet of growing Boer goats without adverse effects on intake and digestibility and to determine its effects on ingestive behavior and physiological responses. Twenty entire, one year old 3/4 Boer goats, 18.1 kg (DS = 2.2) average body weight (BW), were allocated to dietary treatments in a completely randomized design. Each animal was confined in a $1.0\;m^2$ pen with a suspended floor and given ad libitum access to clean, fresh water. Diets were formulated to meet NRC (2007) requirements and the ingredients were: 50% of Tifton-85 (Cynodon sp.) hay, corn meal, soybean meal, mineral and vitamin premix, and licury cake. The treatments were: i) no addition of licury cake to the diet, ii) 15% (DM basis) addition of licury cake, iii) 30% licury cake and, iv) 45% licury cake. The experiment lasted for 17 days; the first 10 days were used to adapt the animals to the diets and facilities. The inclusion of licury cake increased the fiber concentration of the diets; however, there was no effect on either dry matter (DM) or organic matter (OM) intake. There was a linear increase (p<0.05) in the EE content of the diet as the addition of licury cake increased; however, EE intake did not differ (p>0.05) between treatments. The digestibility of non-fibrous carbohydrates (NFC) decreased with increasing inclusion of licury cake, as did NFC intake. The efficiency of ingestion of DM and NDF presented a negative quadratic effect with the inclusion of licury cake. Results from this study indicate that licury cake can be fed to goats at up to 45% of the diet without adverse effects on either intake or digestibility.

Ribeiro, R.D.X.,Oliveira, Ronaldo Lopes,Macome, F.M.,Bagaldo, A.R.,Silva, M.C.A.,Ribeiro, C.V.D.M.,Carvalho, G.G.P.,Lanna, D.P.D. Asian Australasian Association of Animal Productio 2011 Animal Bioscience Vol.24 No.10
This study aimed to establish the optimum level of palm kernel meal in the diet of Santa Ines lambs based on the sensorial characteristics and fatty acid profile of the meat. We used 32 lambs with a starting age of 4 to 6 months and mean weight of $22{\pm}2.75kg$, kept in individual stalls. The animals were fed with Tifton-85 hay and a concentrate mixed with 0.0, 6.5, 13.0 or 19.5% of palm kernel meal based on the dry mass of the complete diet. These levels formed the treatments. Confinement lasted 80 days and on the last day the animals were fasted and slaughtered. After slaughter, carcasses were weighed and sectioned longitudinally, along the median line, into two antimeres. Half-carcasses were then sliced between the 12th and 13th ribs to collect the loin (longissimus dorsi), which was used to determine the sensorial characteristics and fatty acid profile of the meat. For sensorial evaluation, samples of meat were given to 54 judges who evaluated the tenderness, juiciness, appearance, aroma and flavor of the meat using a hedonic scale. Fatty acids were determined by gas chromatography. The addition of palm kernel meal to the diet had no effect on the sensorial characteristics of meat juiciness, appearance, aroma or flavor. However, tenderness showed a quadratic relationship with the addition of the meal to the diet. The concentration of fatty acids C12:0, C14:0 and C16:0 increased with the addition of palm kernel meal, as did the sum of medium-chain fatty acids and the atherogenicity index. Up to of 19.5% of the diet of Santa Ines lambs can be made up of palm kernel meal without causing significant changes in sensorial characteristics. However, the fatty acid profile of the meat was altered.

Cenostigma macrophyllum Tul. var. acuminata Teles Freire (Leguminosae–Caesalpinioideae) is a medicinal plant traditionally used for treatment of gastric ulcer. This study evaluated the ulcer-healing activity of the hydroalcoholic fraction of C. macrophyllum Tul. var. acuminata Teles Freire leaves (Cm-FHA) and the tea of the leaves of C. macrophyllum (Cm-tea), as well as the possible action of Cm-FHA, through in vitro models. Leaves of C. macrophyllum were dried and powdered to obtain the Cm-FHA. Subsequently, the Cm-FHA was characterized phytochemically and biologically. Besides, Cm-tea was prepared. The gastric healing effects of Cm-tea and Cm-FHA were analyzed using the model of acetic acid-induced gastric ulcer in rats. The human gastric adenocarcinoma (AGS) cell line was employed as an in vitro model. Cm-tea promoted a protective effect against gastric ulcers induced by absolute ethanol. Cm-FHA or Cm-tea (100 mg/kg/7 days) exhibited a significant healing effect on ulcers induced by acetic acid. In the histological analysis, gastric mucosa treated with Cm-FHA or Cm-tea advanced restoration of the mucosal epithelium. In vitro, lower concentrations of Cm-FHA stimulated cell proliferation in the BrdU assay and cell migration. Cm-tea and Cm-FHA present a significant gastric healing effect in in vivo and in vitro models.

This study was conducted to evaluate the influence of category (heifers, primiparous or multiparous cows) on pregnancy rates in a large scaleresynchronization ovulation program. Nelore heifers (n = 903), primiparous lactating cows (n = 338) and multiparous lactating cows (n =1,223) were synchronized using a conventional protocol of estradiol/P4-based fixed-time artificial insemination (FTAI). Thirty days afterultrasonography, females who failed the first FTAI were resynchronized with the same hormonal protocol prior to a second FTAI. Thepregnancy status of each cohort was evaluated by ultrasonography 30 days after each FTAI. The average conception rate after the first FTAIand resynchronization was 80.5%. Heifers had a higher conception rate (85%) than primiparous (76%) or multiparous cows (78%; p = 0.0001). The conception rate after the first FTAI was similar among heifers (57%), primiparous cows (51%) and multiparous cows (56%; p = 0.193). After the second FTAI, heifers exhibited a higher conception rate (66%) than primiparous or multiparous cows (51%; p = 0.0001). These resultsdemonstrate the feasibility of resynchronization in large beef herds for providing consistent pregnancy rates in a short period of time. We alsodemonstrated that ovulation resynchronization 30 days after FTAI is particularly effective for heifers, providing a conception rate of up to66%.

Patrícia C. Sousa,Fernando T. Pinho,Manuel A. Alves,Mónica S.N. Oliveira 한국유변학회 2016 Korea-Australia rheology journal Vol.28 No.1
Significant progress has been made over the years on the topic of hemorheology, not only in terms of the development of more accurate and sophisticated techniques, but also in terms of understanding the phenomena associated with blood components, their interactions and impact upon blood properties. The rheological properties of blood are strongly dependent on the interactions and mechanical properties of red blood cells, and a variation of these properties can bring further insight into the human health state and can be an important parameter in clinical diagnosis. In this article, we provide both a reference for hemorheological research and a resource regarding the fundamental concepts in hemorheology. This review is aimed at those starting in the field of hemodynamics, where blood rheology plays a significant role, but also at those in search of the most up-to-date findings (both qualitative and quantitative) in hemorheological measurements and novel techniques used in this context, including technical advances under more extreme conditions such as in large amplitude oscillatory shear flow or under extensional flow, which impose large deformations comparable to those found in the microcirculatory system and in diseased vessels. Given the impressive rate of increase in the available knowledge on blood flow, this review is also intended to identify areas where current knowledge is still incomplete, and which have the potential for new, exciting and useful research. We also discuss the most important parameters that can lead to an alteration of blood rheology, and which as a consequence can have a significant impact on the normal physiological behavior of blood.

In this paper, we describe the antinociceptive activity, molecular modeling and in silico ADMET screening of a series of sulphonyl-hydrazone and sulphonamide imidobenzene derivatives. Among these compounds, the sulphonyl-hydrazones 9 and 11 showed the most potent analgesic activity (ID50 = 5.1 and 6.8 μmol/kg, respectively). Interestingly, all derivatives evaluated in this study have a better analgesic profile than the control drugs, acetyl salicylic acid and acetaminophen. Derivative 9 was the most promising compound; with a level of activity that was 24 times higher than the control drugs. Our SAR study showed a relationship among the distribution of the frontier orbital HOMO coefficients, HOMO-LUMO energy gap of these molecules and their reactivity. The best analgesic compounds (including 6, 9, 10, 11 and 12) fulfilled the Lipinski “rule-of-five”, which is theoretically important for good drug absorption and permeation.

Chitin synthase (CHS) is a glucosyltransferase that converts UDP-N-acetylglucosamine into chitin, one of the main components of fungal cell wall. Class III chitin synthases act directly in the formation of the cell wall. They catalyze the conversion of the immediate precursor of chitin and are responsible for the majority of chitin synthesis in fungi. As such, they are highly specific molecular targets for drugs that can inhibit the growth and development of fungal pathogens. In this work, we have identified and characterized a chitin synthase gene of Moniliophthora perniciosa (Mopchs) by primer walking. The complete gene sequence is 3,443 bp, interrupted by 13 small introns, and comprises a cDNA with an ORF with 2,739 bp, whose terminal region was experimentally determined, encoding a protein with 913 aa that harbors all the motifs and domains typically found in class III chitin synthases. This is the first report on the characterization of a chitin synthase gene, its mature transcription product, and its putative protein in basidioma and secondary mycelium stages of M. perniciosa, a basidiomycotan fungus that causes witches’ broom disease of cacao.

The use of herbal products and/or their derivatives as an alternative or complementary medicine becomes globally popular. To date, various biological activities have been reported in Morinda citrifolia Linn, especially antioxidants, antimicrobial, anti-infammatory and antitumor efects. This study aimed to investigate the genotoxicity and DNA repair capacity of the aqueous fruit extract of M. citrifolia (AEMC). Additionally, we checked the mutagenic capacity of AEMC by the comet assay and micronucleus tests in rats. For this, rats (n=10; 5 males and 5 females) were divided into fve groups as: negative control (distilled water); positive control (25 mg/kg of cyclophosphamide, i.p.); and three groups for AEMC (2.5, 5 and 10 mg/kg, i.p.). The results suggest that, the AEMC induced genotoxicity in white blood cells, but a DNA repair capacity was also observed after 72 h of AEMC exposure. AEMC also showed cytotoxicity and mutagenicity in liver and kidney cells of rats at 5 and 10 mg/kg doses. In conclusion, AEMC exhibited a dose-dependent cytotoxicity, genotoxicity and mutagenicity along with a time-dependent DNA repair capacity in rats. Further studies are necessary regarding the safe use of this medicinal plant for human consumption.

Chrysobalanus icaco L. is a medicinal plant present in the Brazilian coastline and known for its hypoglicemic and antioxidant properties. Here, we assessed the beneficial metabolic effects of the aqueous extract of C. icaco (AECI) leaves in diet-induced obese mice. Swiss mice were fed standard chow (SC used as controls) or high-fat diet (HFD) to induce obesity. After 10 weeks, mice on each diet were divided into two groups with one group used as control while the other group treated with AECI for 4 weeks resulting in four groups of mice: SC; SC treated with AECI (SC + AECI); HFD; and HFD treated with AECI (HFD + AECI). AECI was administered drinking water at about 200 mg/kg. AECI was able to normalize insulin (13,682 ± 1090 vs. 9828 ± 485 AU, P < .05) and fasting blood glucose (192.8 ± 14.2 vs. 132.3 ± 6.4 mg/dL, P < .05) and inhibit weight gain (39 ± 5.7%) and fat storage in liver (72.60 ± 3.83%, P < .0001), despite the high-fat intake. These findings reinforce the use of AECI in hyperglycemia and highlight the potential extract’s effect in preventing weight gain and fat accumulation in liver of diet-induced obese mice.
