Biomarcadores vem sendo utilizados para monitorar o uso do álcool e, atualmente, os mais sensíveis e específicos são enzimas hepáticas, por exemplo, gama glutamiltransferase (GGT), alanina aminotransferase (ALT), aspartato aminotransferase (AST) e fosfatase alcalina (ALP). Verificar, a partir da experimentação animal, as alterações provocadas pelo uso de álcool e pela prática de atividade física nas enzimas hep...
OBJECTIVE: To test whether swimming training benefits femoral neck strength in young diabetic rats under insulin therapy. METHODS: A total of 60 male Wistar rats (age: 40 days) were divided equally into the following six groups: control sedentary, control exercise, diabetic sedentary, diabetic exercise, diabetic sedentary plus insulin and diabetic exercise plus insulin. Diabetes was induced with a unique intrap...
The cardiovascular system plays a direct role in the maintenance of body temperature. Whether passive heating alters cardiovascular autonomic modulation in conscious rats is still unknown. This study investigated the effects of passive heating on systolic blood pressure variability (SBPV) and heart rate variability (HRV) in conscious rats and the involvement of the renin-angiotensin system in the passive heatin...
A lesão medular resulta em déficits neurológicos graves, a maioria irreversíveis. A terapia celular representa uma estratégia para o tratamento, especialmente com a utilização de células-tronco, com resultados satisfatórios em vários modelos experimentais. O objetivo do estudo foi comparar o tratamento de lesões da medula espinal (SCI), com e sem o uso de células-tronco mesenquimais (MSC), para investigar se as...
O conhecimento das características das glândulas salivares labiais vem se tornando importante à medida que aquelas vêm sendo empregadas, na medicina veterinária, como transplante autógeno para promover lubrificação da superfície ocular. As glândulas salivares labiais, juntamente com a mucosa oral, foram removidas de 10 cadáveres de cães adultos, como peça única, no lábio inferior esquerdo, da região anatômica d...
We tested the effects of early mesenchymal stem cell (MSC) therapy associated with endurance exercise on the structural and functional cardiac remodeling of rats with myocardial infarctation (MI). Male Wistar rats (40 days old) were divided into 6 groups: control and exercise sham; control and exercise MI; and control and exercise MI MSC. MI was surgically induced and bone marrow-derived MSCs were immediately i...
Cardiomyocytes have small potential for renovation and proliferation in vivo. Consequently, the heart muscle has limited capacity of self-renewal. Mesenchymal stem cells (MSC) therapy, as well as MSC differentiated into cardiomyocytes, has been used in the attempt to minimize the effects of ischemic-hypoxic lesions and those affecting the electrical conduction system of the heart. The present study compared thr...
