Cardiac gene expression and systemic cytokine profile are complementary in a murine model of post-ischemic heart failure
Provedor de dados: 56
Autores: Lachtermacher,S.; Esporcatte,B.L.B.; Montalvão,F.; Costa,P.C.; Rodrigues,D.C.; Belem,L.; Rabischoffisky,A.; Faria Neto,H.C.C.; Vasconcellos,R.; Iacobas,S.; Iacobas,D.A.; Dohmann,H.F.R.; Spray,D.C.; Goldenberg,R.C.S.; Campos-de-Carvalho,A.C.
After myocardial infarction (MI), activation of the immune system and inflammatory mechanisms, among others, can lead to ventricular remodeling and heart failure (HF). The interaction between these systemic alterations and corresponding changes in the heart has not been extensively examined in the setting of chronic ischemia. The main purpose of this study was to investigate alterations in cardiac gene and systemic cytokine profile in mice with post-ischemic HF. Plasma was tested for IgM and IgG anti-heart reactive repertoire and inflammatory cytokines. Heart samples were assayed for gene expression by analyzing hybridization to AECOM 32k mouse microarrays. Ischemic HF significantly increased the levels of total serum IgM (by 5.2-fold) and total IgG (by...

Human umbilical cord blood cells in infarcted rats
Provedor de dados: 56

Therapy with bone marrow-derived cells has been used in ischemic patients with reported success. The aim of this study was to determine the therapeutic efficacy of fresh and frozen human umbilical cord blood cells (hUCB) in Wistar rats submitted to permanent occlusion of the left coronary artery. Three hours after myocardial infarction, 2 x 10(7) hUCB cells or vehicle were administered by intramyocardial injection. The animals were divided into five groups: control (N = 10), sham operated (N = 10), infarcted that received vehicle (N = 9), infarcted treated with cryopreserved hUCB (N = 7), and infarcted treated with fresh hUCB (N = 5). Cardiac function was evaluated by electrocardiogram (ECG) and echocardiogram (ECHO) before cell therapy, and by ECG, ECHO,...

An ultrasound and histomorphological analysis of experimental liver cirrhosis in rats
Provedor de dados: 56
Autores: Dias,J.V.; Paredes,B.D.; Mesquita,L.F.Q.; Carvalho,A.B.; Kozlowski,E.O.; Lessa,A.S.; Takiya,C.M.; Resende,C.M.C.; Coelho,H.S.M.; Campos-de-Carvalho,A.C.; Rezende,G.F.M.; Goldenberg,R.C.S.
We investigated whether liver injury by dual exposure to ethanol and carbon tetrachloride (EtOH + CCl4) for 15 weeks would persist after hepatotoxic agents were removed (EtOH + CCl4/8wR). After 15 weeks of hepatic injury with ethanol (5.5%, m/v) and carbon tetrachloride (0.05, mL/kg, ip), 5 of 11 female Wistar rats were sacrificed. The other 6 rats were maintained for an additional 8 weeks without hepatotoxic agents. Ultrasonography showed increased liver echogenicity and dilation of portal vein caliber in both groups (EtOH + CCl4: 0.22 ± 0.01 cm, P &lt; 0.001; EtOH + CCl4/8wR: 0.21 ± 0.02 cm, P &lt; 0.01) vs control (0.16 ± 0.02 cm). Histopathology showed regenerative nodules in both experimental groups. Histomorphometry revealed increased fibrosis...
