Restricted intake and lipid inclusion in Santa Inês ewe lambs diet: age, weight and progesterone concentration at first ovulation.

Abstract: The age at first ovulation is influenced by several factors, and nutrition has an essential role on it. Lipids provide essential fatty acids that are positively associated to reproductive aspects. The aims of this study were to evaluate the effects of lipid inclusion and restricted intake on age and weight at the first ovulation and the serum progesterone (P4) concentration at the sixth day after first ovulation. Thirty-five Santa Inês ewe lambs with initial body weight (BW) of 21.5 ± 0.3 kg and age of 91.6 ± 1.4 days were used. Animals were blocked according to initial BW and distributed to one of four treatments: animals receiving diet without lipid inclusion (3.5% ether extract ? EE), ad libitum intake (WLI-ALI, control group, n = 9); diet without lipid inclusion and restricted intake (WLI-RI, n = 9); lipid inclusion diet, represented by toasted and broken soybean (9.8% EE), ad libitum intake (LIP-ALI, n = 8); and lipid inclusion diet and restricted intake (LIP-RI, n = 9). Ewe lambs subjected to restricted intake had 84% of the diet offered to those in ad libitum treatments. The individual daily dry matter intake (DMI) and EE intake (EEI) were measured and the animals were weekly weighted until 35 kg BW. For P4 analysis, blood samples were collected once a week after the animals reached 25 kg BW and twice a week after 30 kg until 35 kg BW. Ovulation was estimated to occur on the sixth day before P4 ?1 ng/mL. DMI, EEI, average daily weight gain until first ovulation (DWG), weight and age at first ovulation, serum P4 concentration and days in experiment until first ovulation were analyzed by GLM PROC of the SAS software (version 9.3). Ovulation occurred in 60% (21/35) of the ewe lambs (5; 5; 6; 5 from WLI-ALI; WLI-RI; LIP-ALI; and LIP-RI, respectively). DMI of ewe lambs from WLI-ALI group was greater (P 0.05) among WLI-ALI, WLI-RI, LIP-ALI, and LIP-RI treatments, respectively. The first ovulation in Santa Inês ewe lambs occurs at 30 kg BW. The restricted intake imposed in this study did not delay the age at fist ovulation. The greater lipid intake did not favor reproductive parameters. Serum P4 did not increase with the soybean inclusion in the diet. [Restrição alimentar e suplementação lipídica: idade, peso e concentração de progesterona até a primeira ovulação]. Resumo: A idade da primeira ovulação é influenciada por vários fatores e a nutrição tem um papel essencial. Lipídios fornecem ácidos graxos essenciais que estão associados de forma positiva aos aspectos reprodutivos. Os objetivos deste estudo foram avaliar os efeitos da inclusão lipídica e da restrição do consumo na idade e peso a primeira ovulação e na concentração sérica de progesterona (P4) no sexto dia após a primeira ovulação. Foram utilizadas trinta e cinco cordeiras Santa Inês com peso corporal (PC) inicial de 21,5±0,3 kg e idade de 91,6±1,4 dias. Os animais foram blocados de acordo com o PC inicial e distribuído a um dos quatro tratamentos: animais que receberam dieta sem inclusão de lipídeos (3,5% de extrato etéreo - EE), consumo ad libitum (SEM-ALI, grupo controle, n=9); dieta sem inclusão de lipídeos e restrição do consumo (SEMRE, n=9); dieta com inclusão lipídica, representada pela soja tostada e quebrada (9,8% EE), consumo ad libitum (LIP-ALI, n=8); e dieta com inclusão lipídica e restrição do consumo (LIP-RE, n=9). Cordeiras submetidas a restrição do consumo tiveram 84% da dieta oferecida em comparação aos tratamentos ad libitum. O consumo individual diário de matéria seca (CMS) e de EE (CEE) foram mensurados e os animais foram pesados semanalmente até 35 kg de PC. Para a análise de P4, amostras de sangue foram coletadas uma vez por semana depois que os animais atingiram 25 kg de PC e duas vezes por semana após 30 kg até 35 kg de PC. Estimou-se que a ovulação ocorreu no sexto dia que antecedeu P4?1 ng/mL. CMS, CEE, ganho de peso médio diário até a primeira ovulação (GPD), peso e idade da primeira ovulação, a concentração sérica de P4 e dias em experimento até a primeira ovulação foram analisados pelo PROC GLM do software SAS (versão 9.3). A ovulação ocorreu em 60% (21/35) das cordeiras (5; 5; 6; 5 do SEM-ALI; SEM-RE; LIP-ALI e LIP-RE, respectivamente). CMS de cordeiras do grupo SEM-ALI foi maior (P0,05) entre os tratamentos SEM-ALI, SEM-RE, LIP-ALI e LIP-RE, respectivamente. A primeira ovulação em borregas Santa Inês ocorreu com 30 kg de PC. A restrição do consumo imposta neste estudo não retardou a idade a primeira ovulação. A maior ingestão de lipídios não favoreceu os parâmetros reprodutivos. A P4 sérica não aumentou com a inclusão de soja na dieta.Proceedings of the 30th Annual Meeting of the Brazilian Embryo Technology Society (SBTE); Foz do Iguaçu, PR, Brazil, August 25th to 27th, 2016, and 32nd Meeting of the European Embryo Transfer Association (AETE); Barcelona, Spain, September 9th and 10th, 2016

New segregates from the Neotropical genus Stryphnodendron (Leguminosae, Caesalpinioideae, mimosoid clade)

Non-monophyly is a prominent issue in mimosoid legumes, even in some of the less speciose genera such as the neotropical genus Stryphnodendron. This genus includes 35 species occurring from Nicaragua to Southern Brazil mostly in humid forests and savannas. Previous taxonomic studies of Stryphnodendron have highlighted morphologically distinct groups within the genus, recognized by differences on leaves (number of pinnae and size of leaflets), inflorescences (a simple or compound thyrse), and fruit types (legume, nucoid legume or follicle). Recent phylogenetic analyses have confirmed the non-monophyly of Stryphnodendron, supporting the recognition of three independent and morphologically well-delimited genera. Here we re-circumscribe Stryphnodendron and propose the two new genera Gwilymia and Naiadendron. In addition, we also provide an updated taxonomic account of the closely related genus Microlobius, including the proposal of a lectotype for the single species in the genus

Quality of life as a prognostic marker in pulmonary arterial hypertension

Background: Improvement in quality of life together with better survival are the ultimate goals in the treatment of pulmonary arterial hypertension (PAH) patients. the objective of this study was to evaluate the health-related quality of life (HRQL) of pulmonary arterial hypertension (PAH) patients with the SF-36 generic questionnaire and to identify the prognostic implication of this assessment.Methods: Fifty-four consecutive newly diagnosed PAH patients (WHO classification group I) in a single PAH reference center were included. Patients were evaluated at baseline for clinical and hemodynamic parameters, and they subsequently received first-line therapy with either an endothelin receptor antagonist or a phosphodiesterase-5 inhibitor. After 16 weeks of specific PAH therapy, all patients were re-evaluated using a 6MWT and a SF 36 questionnaire, and then they were followed up for at least 36 months.Results: After treatment, the patients demonstrated an improved 6MWT (414 +/- 124 m vs. 440 +/- 113 m, p = 0.001). Specific PAH therapy also improved the HRQL scores.Patients with a baseline Physical Component Score (PCS) higher than 32 had a better survival rate than those who had a score under 32 (p = 0.04). Similarly, patients with a PCS of at least a 38 after the 16 week therapy period had a better survival rate when compared with those who did not achieve this value (p = 0.016). Unlike the absolute PCS values, the post-treatment PCS variability was unable to predict better survival rates (p = 0.58).Conclusions: Our findings suggest that HRQL is associated with prognosis in PAH. Furthermore, achieving pre-determined PCS scores might represent a specific goal to be reached in treatment-to-target strategies.Univ São Paulo, Sch Med, Pulm Dept, Inst Heart, BR-05403000 São Paulo, BrazilUniversidade Federal de São Paulo, Rheumatol Dept, São Paulo, BrazilUniversidade Federal de São Paulo, Rheumatol Dept, São Paulo, BrazilWeb of Scienc

Integration of miRNA and mRNA expression profles reveals microRNA-regulated networks during muscle wasting in cardiac cachexia

Cardiac cachexia (CC) is a common complication of heart failure (HF) associated with muscle wasting and poor patient prognosis. Although different mechanisms have been proposed to explain muscle wasting during CC, its pathogenesis is still not understood. Here, we described an integrative analysis between miRNA and mRNA expression profiles of muscle wasting during CC. Global gene expression profiling identified 1,281 genes and 19 miRNAs differentially expressed in muscle wasting during CC. Several of these deregulated genes are known or putative targets of the altered miRNAs, including miR-29a-3p, miR-29b-3p, miR-210-5p, miR-214, and miR-489. Gene ontology analysis on integrative mRNA/miRNA expression profiling data revealed miRNA interactions affecting genes that regulate extra-cellular matrix (ECM) organization, proteasome protein degradation, citric acid cycle and respiratory electron transport. We further identified 11 miRNAs, including miR-29a-3p and miR-29b-3p, which target 21 transcripts encoding the collagen proteins related to ECM organization. Integrative miRNA and mRNA global expression data allowed us to identify miRNA target genes involved in skeletal muscle wasting in CC. Our functional experiments in C2C12 cells confirmed that miR-29b down-regulates collagen genes and contributes to muscle cell atrophy. Collectively, our results suggest that key ECM-associated miRNAs and their target genes may contribute to CC in HF

Effect of live Eimeria vaccination or salinomycin on growth and immune status in broiler chickens receiving in-feed inclusion of gelatin and vitamin E

This experiment determined if 2% of gelatin, to improve the levels of proline and glycine in the diet, and 70 mg/kg of vitamin E supplementation would relieve the impaired performance of male Cobb broilers vaccinated for coccidiosis. Half of the chicks were vaccinated via water (live oocysts), while the other half received medication (salinomycin) in the feed until 35 d of age. The effects of coccidiosis vaccine on performance and mRNA levels of genes involved in mucin synthesis, cytokines, trefoil family factor-2 (TFF2), and metabolic processes (CD36) in the jejunum of broilers were measured. Vaccination negatively affected performance in the first 21 d; however, the inclusion of gelatin and vitamin E reduced this negative response. Additionally, supplementation with these nutrients led to an improvement in broilers receiving the coccidiostat (P < 0.05). From 21 to 35 d, birds treated with gelatin and coccidiosis vaccine experienced better body weight gain than birds without gelatin and vitamin E (P < 0.05). Vaccinated chickens had decreased body weight and decreased anti-inflammatory cytokine expression. Fur- thermore, they had increased inflammatory cytokine expression, mucin 2 expression, and TFF2 compared to salinomycin-fed broilers (P < 0.05). Transcripts for IL- 1B, IFN-y, MUC2, TFF2 were decreased while mRNAs for IL-4 and IL-10 increased in salinomycin-fed broilers compared to vaccinated broilers (P < 0.05). In conclusion, broilers vaccinated against coccidiosis increase their pro-inflammatory immune status and mucin expression compared to broilers receiving salinomycin. These events may contribute to lower performance in vaccinated broiler chicks. Moreover, vitamin E and gelatin can minimize the vaccine’s negative immune effects and promote better performance

Vesicular stomatitis virus chimeras expressing the oropouche virus glycoproteins elicit protective immune responses in mice

Oropouche virus (OROV) infection of humans is associated with a debilitating febrile illness that can progress to meningitis or encephalitis. First isolated from a forest worker in Trinidad and Tobago in 1955, the arbovirus OROV has since been detected throughout the Amazon basin with an estimated 500,000 human infections over 60 years. Like other members of the famil
