1. Bioelectrical Impedance Analysis for Monitoring Fluid and Body Cell Mass Changes in Patients Undergoing Cardiopulmonary Bypass
Abstract Objective: To evaluate preoperative and postoperative body fluid distribution with a bioelectrical impedance analyzer in patients undergoing cardiopulmonary bypass. Methods: Fifteen adult patients undergoing cardiopulmonary bypass were included in this study. Total body fluid changes, basal metabolism rates, body fat masses, lean body masses, and

3. Extracellular diffusion quantified by magnetic resonance imaging during rat C6 glioma cell progression
Solution reflux and edema hamper the convection-enhanced delivery of the standard treatment for glioma. Therefore, a real-time magnetic resonance imaging (MRI) method was developed to monitor the dosing process, but a quantitative analysis of local diffusion and clearance parameters has not been assessed. The objective of this study was to compare diffusion

4. Fluid distribution kinetics during cardiopulmonary bypass
OBJECTIVE: The purpose of this study was to examine the isovolumetric distribution kinetics of crystalloid fluid during cardiopulmonary bypass. METHODS: Ten patients undergoing coronary artery bypass grafting participated in this prospective observational study. The blood hemoglobin and the serum albumin and sodium concentrations were measured repeatedly

5. Immobilization and therapeutic passive stretching generate thickening and increase the expression of laminin and dystrophin in skeletal muscle
Extracellular matrix and costamere proteins transmit the concentric, isometric, and eccentric forces produced by active muscle contraction. The expression of these proteins after application of passive tension stimuli to muscle remains unknown. This study investigated the expression of laminin and dystrophin in the soleus muscle of rats immobilized with the

6. Mapping and signaling of neural pathways involved in the regulation of hydromineral homeostasis
Several forebrain and brainstem neurochemical circuitries interact with peripheral neural and humoral signals to collaboratively maintain both the volume and osmolality of extracellular fluids. Although much progress has been made over the past decades in the understanding of complex mechanisms underlying neuroendocrine control of hydromineral homeostasis, s

7. GABA and glutamate transporters: new events and function in the vertebrate retina
The neural retina is a highly complex tissue composed of excitatory and inhibitory neurons and glial cells. Glutamate, the main excitatory neurotransmitter, mediates information transfer from photoreceptors, bipolar cells, and ganglion cells, whereas interneurons, mainly amacrine and horizontal cells, use γ-aminobutyric acid (GABA), the main inhibitory neur

8. Modelagem da Microestrutura de Tecidos Cardíacos
A few decades ago the cardiac tissue was believed to be an uniformly connected continumm. Currently, it is known that the cardiac cells are connected to each other via special protein channels called gap junctions, through which the ionic current flows between neighboring cells. The cardiac cells are arranged in distinct layers of muscle fibers surrounded by

9. Correlação da pressão coloidosmótica com a evolução clínica de cadelas com sepse submetidas a tratamento intensivo / Correlation of colloid osmotic pressure with clinical progress in female dogs with septicemia submitted to intensive therapy
Sepsis induces increased vascular permeability, translocation and albumin loss to extracellular space, resulting in hypoalbuminemia and lower plasma colloid osmotic pressure. This study correlate colloid osmotic pressure with the clinical progress of 41 female dogs presenting severe sepsis or sepsis shock due to pyometra, submitted to ovario-salpingo-hystere

10. Participação do L-NAME, da L-arginina e da N-acetilcisteína no enfisema pulmonar induzido por fumaça de cigarro em camundongos / The lung remodeling in mouse emphysema is independent of nitric oxide modulation
Nitric oxide (NO) represents one of the most important intra and extracellular mediators/messengers. It takes part in both biologic and pathologic processes. This study aimed to verify NO role in pulmonary emphysema induced by cigarette smoke (CS) in mice. So L-NAME (LN) (a NOinhibitor) and L-arginine (LA) (a substract for NO formatio

11. Immunolocalization of galectin-3 in mouse public symphysis during pregnancy and post-partum / Imunolocalização de galectina-3 na sinfise pubica de camundongos durante a prenhez e pos-parto
It is recognized that the pubic symphysis of some mammal species, including mice, undergoes structural transformations during pregnancy and post-partum. These transformations include the emerging of an interpubic ligament and softening of this tissue in the two last days of pregnancy. This ligament allows the pelvic bones separation, warranting fetus self pa

12. Estudo histológico do tecido conjuntivo areolar perifascial implantado em pregas vocais de coelhos / Histological study of implanted perifascial areolar tissue in rabbit´s vocal folds
Besides the great development of phonosurgery over the previous decades, vocal fold stiffness is a difficult disease that remains a therapeutic challenge. It may be either caused by cicatricial fibrosis or be associated with minor structural alterations of the vocal fold mucosa, mainly represented by deep sulcus vocalis. In both cases, there is loss and diso
