    Objetivou-se avaliar a importancia dos efeitos de linhagem citoplasmatica sobre as caracteristicas peso corporal (PCORP), peso de velo sujo (PVS) e diametro da fibra da la (DIAM), respectivamente em 707 e 703 femeas e 350 machos da raca Merino com um ano de idade. Linhagens citoplasmaticas (LCT) foram definidas como as primeiras 41 femeas do pedigree registradas no Brasil, na decada de 30. Informacoes de pedigree incluiram 30640 animais e, em media, 10 geracoes. As avaliacoes foram feitas usando-se metolologia da Maxima Verossimillanca Restrita, sob modelo animal. Para cada caracteristica foram feitas analises com tres modelos (modelo com efeito direto; modelo com efeitos direto e de LCT; e modelo com efeitos direto, materno e de LCT). Os modelos matematicos foram comparados, sequencialmente, do mais simples para o mais complexo pelo teste da razao das verossimilhancas. Nao houve diferencas (P>0,05) entre os modelos onde se inclui e aqueles onde se omitiu o efeito de LCT, indicando nao serem importantes os efeitos citoplasmaticos para as caracteristicas estudadas. Para PCORP, os resultados indicaram haver confundimento parcial entre efeito genetico aditivo materno e feito de LCT. A importancia relativa dos componentes devido ao efeito genetico aditivo materno foi maior para a caracteristica PCORP (26,1;26,3 e 37,1%), seguido dos para PVS (19,5 para os tres modelos) e DA (16,3 para os tres modelos).Resumo expandid

    Administration of hCG on the seventh day after initiation of estrus may circumvent negative effects of cervical relaxation protocol in sheep: Preliminary results.

    Cervical relaxation with association of estradiol benzoate, cloprostenol and oxytocin allows a cervical transposition and embryo collection in sheep by the non-surgical method (Fonseca et al., Theriogenology, 86: 144-151, 2016). However, in recipients, the use of this protocol becomes impracticable due to the use of cloprostenol, which is a luteolytic agent. Sheep are known to form accessory luteal bodies after hCG administration seven days after the onset of estrus (Castro et al., Anim. Reprod., 12: 148, 2015). Therefore, the objective of this study was to develop a cervical relaxation protocol in embryo recipient ewes without compromising future gestation. The data were presented in a descriptive way. Thirteen ewes were observed in estrus out of 24 females submitted to the synchronization protocol. The pregnancy rate were 75.0% (3/4) in G1, 0.0% in G2 (0/5) and 50.0% in G3 (2/4). Preliminary results suggest that the association of estradiol benzoate and oxytocin may compromise the onset of pregnancy and that the use of hCG at the end of the protocol in D7 can circumvent partially these negative effects, allowing the establishment of pregnancy

    Comparative study on myelotoxic and antineoplastic action of Synadenium umbellatum, Vitis vinifera and Resveratrol

    Cancer is one of the pathologies that most challenge medicine, not only because of the complexity of its development, but also because of the difficulty of treatment that is not always effective. Due to the significant toxicity and adverse effects profile presented by the main chemotherapeutic agents used to treat neoplasm, there is a constant interest in the search for new drugs that may be a more effective alternative. Therefore, the search for new compounds of plant origin becomes an interesting tool for the discovery of drugs with antitumor activity. Synadenium umbellatum is a plant native to tropical Africa known as “cola-nota”, “hazel”, “cancerous”, “miraculous”, among others. The plant is used by the Brazilian population as having anti-inflammatory, analgesic, antineoplastic properties, among others. However, the literature is lacking on reports of the toxicity of Synadenium umbellatum macerate. Resveratrol is a polyphenolic compound found in different plant species, mainly in grape species (Vitis) and their seeds. Vitis vinifera is a species of grape easily found in several regions, also containing a high concentrations of phenolic compounds, including resveratrol in its fruits, leaves and seeds. Therefore, this study was aimed to evaluate the myelotoxicity of macerate, extract and resveratrol and their antitumor activity in Balb/c mice with Ehrlich tumor. The hematological evaluation was obtained by flow cytometry and the tumors were measured using a pachymeter and the tumor masses by means of weighing. No statistically significant difference was observed between results from the control group and the treatment groups. It was concluded that macerate, crude extract and resveratrol did not demonstrate a myelotoxic effect and did not cause a decrease in tumor mass1928086sem informaçã

    Quality of life on hemodialysis and inflammation: a descriptive analysis

    Chronic kidney disease (CKD) is highly prevalent worldwide. Patients with CKD on hemodialysis are more likely to present behavioral changes and worse quality of life as a result of their routine and complications. They also have higher levels of cytokines. The aim of this study is to assess the relationship between the inflammatory profile and quality of life measured by KDOQL-SF36 in hemodialysis outpatients. Patients older than 21 years of age and on routine hemodialysis for at least 6 months with treatment on a regular weekly basis were included and their anthropometric parameters and serum inflammatory markers were evaluated. Thirty patients consented to participate. Homocysteine (Hcy) levels were correlated with worse glomerular filtration rate (GFRP=0.003) and creatinine (P=0.002). IL-6 was not correlated with worse nutritional status taking into account body mass index (BMIkg/m(2)P=0.83). On the other hand, TNF-alpha was positively correlated with albumin (P=0.008), nutritional status by BMI (P=0.04), and nutritional status by arm circumference area (P=0.04). IL-6 was correlated with activity limitation (P=0.02) and Hcy with work status (P=0.04). Hcy was correlated with nutritional status and inflammatory markers. In this population, the majority of the sections in KDOQL-SF36 were not correlated with cytokines levels.Fac Med ABC, Dept Clin Med, Santo Andre, SP, BrazilFac Med ABC, Lab Anal Clin, Santo Andre, SP, BrazilFac Med ABC, Lab Epidemiol & Anal Dados, Santo Andre, SP, BrazilUniv Fed Sao Paulo, Dept Ciencias Farmaceut, Diadema, SP, BrazilUniv Fed Sao Paulo, Dept Ciencias Farmaceut, Diadema, SP, BrazilWeb of Scienc
