1. Is handgrip strength normalized to body weight a useful tool to identify dynapenia and functional incapacity in post-menopausal women?
ABSTRACT Objective To investigate whether handgrip strength normalized to body weight could be a useful clinical tool to identify dynapenia and assess functional capacity in post-menopausal women. Method A total of 136 postmenopausal women were recruited. Body composition (Dual Energy X-ray Absorptiometry [DEXA], Bio-electrical Impedence Analysis [BIA]), g

2. Estudo eletroquÃmico da adsorÃÃo de molÃculas organosulfuradas sobre superfÃcie de ouro. / Electrochemical study of the adsorÃÃo of moleculas organosulfuradas on gold surface.
Modified gold surface with organosulfur species, 1,4-dithiane (1,4-dt) and 4- mercaptopyridine (pyS), was studied in this work. The study was carried out using the following electrochemical techniques: linear polarization with rotate disk electrode, cyclic voltammetry, differential pulse voltammetry, electrohydrodynamic impedance and electrochemical impedanc

3. Measurement of tissue impedence in conjunction with computed tomography-guided stereotaxic biopsies.
Twenty-two patients undergoing CT-guided stereotaxic biopsies had intraoperative monopolar and bipolar impedance monitoring along the trajectory of the biopsy. Patterns of tissue impedance were retrospectively correlated with CT scans demonstrating decreased impedance generally corresponding to low density regions and increased impedance to the enhancing les

4. Synovial fluids facilitate small solute diffusivity.
The diffusivity of water, fucose, proline, lysine, glutamic acid, glucose and sucrose was determined in a variety of inflammatory human synovial fluids. In view of the constituents of pathological synovial fluids one would predict impedence to solute movement. In several fluid diffusivity was enhanced relative to translational diffusion in water. In most flu

5. Diffusion of injected macromolecules within the cytoplasm of living cells.
The diffusion of macromolecules introduced into the cytoplasm of human fibroblasts by erythrocyte-mediated microinjection was measured by the fluorescence recovery after photobleaching technique. The apparent diffusion coefficients for fluorescein-labeled IgG and fluorescein-labeled bovine serum albumin were approximately 10(-8) cm2/sec at 22 degrees C, cons

6. Afterload reduction: a comparison of captopril and nifedipine in dilated cardiomyopathy.
Nifedipine and captopril are potent vasodilators and may be expected to help left ventricular failure by reducing afterload. Nifedipine (20 mg three times a day) and captopril (50 mg three times a day) were added to an optimal regimen of digitalis and diuretics in a double blind crossover trial in 18 cases of dilated cardiomyopathy.

7. Cotton induced bronchoconstriction detected by a forced random noise oscillator.
Lung function responses to inhaled cotton dust were evaluated in a group of 58 healthy subjects by spirometry (MEFV curves) and forced random noise impedance parameters. Twenty-one of these subjects were also examined by body plethysmography to assess changes in airway resistance (Raw). For the study group as a whole, alterations in lung mechanical function

8. Role of aortic input impedance in the decreased cardiovascular response to exercise with aging in dogs.
The diminished cardiac output response to exercise with advancing age may be attributable to intrinsic inability of the old ventricle to respond appropriately and/or to an additional loading imposed upon the ventricle by the aged vascular system. The steady (resistance) and pulsatile (characteristic impedance) load components together comprise the vascular l
