1. TP53 codon 72 polymorphism as a risk factor for cardiovascular disease in a Brazilian population
TP53, a tumor suppressor gene, has a critical role in cell cycle, apoptosis and cell senescence and participates in many crucial physiological and pathological processes. Identification of TP53 polymorphism in older people and age-related diseases may provide an understanding of its physiology and pathophysiological role as well as risk factors for complex d

2. Reajustes posturais em individuos neurologicamente normais e em portadores da Sindrome de Down na gangorra : efeito da manipulação sensorial / Postural adjustaments during balance on seesaw : the effect of sensorial stimulation
Introduction: The main of this study was investigates the sensory integration and function in neurological (CG) and Down syndrome (DS) subjects during balance on unstable seesaw. Methods: Eight individuals with DS and eight CG were studied. Six balancing conditions were collected combining 3 seesaw heights and two manipulations: Galvanic Vestibular Stimulati

3. Characteristics of the balance of rowers trunk in the seated position / Características do equilíbrio de tronco de remadores na posição sentada
The objective of this study was to evaluate the characteristics of the balance of rowers trunk, in the seated position. The research is characterized as descriptive exploratory, having 30 rowers of the male sex with age between 15 and 28 years old as participants. The data was collected using the Board of balance, developed by Soares (2004), constituted of a

5. Fractal dynamics in physiology: Alterations with disease and aging
According to classical concepts of physiologic control, healthy systems are self-regulated to reduce variability and maintain physiologic constancy. Contrary to the predictions of homeostasis, however, the output of a wide variety of systems, such as the normal human heartbeat, fluctuates in a complex manner, even under resting conditions. Scaling techniques

6. Pathogenicity and virulence: another view.
The concepts of pathogenicity and virulence have governed our perception of microbial harmfulness since the time of Pasteur and Koch. These concepts resulted in the recognition and identification of numerous etiological agents and provided natural and synthetic agents effective in therapy and prevention of diseases. However, Koch's postulates--the premier pr

7. Preferential exclusion of sucrose from recombinant interleukin-1 receptor antagonist: Role in restricted conformational mobility and compaction of native state
Understanding the mechanism for sucrose-induced protein stabilization is important in many diverse fields, ranging from biochemistry and environmental physiology to pharmaceutical science. Timasheff and Lee [Lee, J. C. & Timasheff, S. N. (1981) J. Biol. Chem. 256, 7193–7201] have established that thermodynamic stabilization of proteins by sucrose is due to

8. Delayed K+ clearance associated with aquaporin-4 mislocalization: Phenotypic defects in brains of α-syntrophin-null mice
Recovery from neuronal activation requires rapid clearance of potassium ions (K+) and restoration of osmotic equilibrium. The predominant water channel protein in brain, aquaporin-4 (AQP4), is concentrated in the astrocyte end-feet membranes adjacent to blood vessels in neocortex and cerebellum by association with α-syntrophin protein. Although AQP4 has bee

9. Biosorption of dichlorodiphenyltrichloroethane and hexachlorobenzene in groundwater and its implications for facilitated transport.
The potential for enhanced mobility of hydrophobic pollutants by cotransport with bacteria in saturated soils was evaluated from measurements of biosorption of 14C-labeled hexachlorobenzene and dichlorodiphenyltrichloroethane (DDT) to five strains of soil and sewage bacteria. The sorption process could be described by a linear partition equation and appeared

10. Calcium diffusion enhanced after cleavage of negatively charged components of brain extracellular matrix by chondroitinase ABC
The concentration of extracellular calcium plays a critical role in synaptic transmission and neuronal excitability as well as other physiological processes. The time course and extent of local fluctuations in the concentration of this ion largely depend on its effective diffusion coefficient (D*) and it has been speculated that fixed negative charges on cho

11. Agonist action of taurine on glycine receptors in rat supraoptic magnocellular neurones: possible role in osmoregulation.
1. To evaluate the implication of taurine in the physiology of supraoptic neurones, we (i) investigated the agonist properties of taurine on glycine and GABAA receptors of supraoptic magnocellular neurones acutely dissociated from adult rats, using whole-cell voltage clamp, (ii) studied the effects of taurine and strychnine in vivo by extracellular recording
