Patients with sickle cell disease exhibits numerous kidney structural and functional abnormalities, changes that are seen along the entire length of the nephron. Changes are most marked in patients with homozygous sickle cell anemia, but are also seen in those with compound heterozygous states and the sickle cell trait. The renal features of sickle cell disease include some of the most common reasons for referral to nephrologists, such as hematuria, proteinuria, tubular disturbances and chronic kidney disease...

The advent of new signal processing methods, such as non-linear analysis techniques, represents a new perspective which adds further value to brain signals' analysis. Particularly, Lempel-Ziv's Complexity (LZC) has proven to be useful in exploring the complexity of the brain electromagnetic activity. However, an important problem is the lack of knowledge about the physiological determinants of these measures. Although a correlation between complexity and connectivity has been proposed, this hypothesis was never tested in vivo...

The authors report nine patients with systemic lupus erythematosus associated with anti-topoisomerase I antibodies (ELISA test) without features of systemic sclerosis. These antibodies were correlated with the disease activity and might be a marker of the severity of the closely related to difusse proliferative glomerulonephritis.

The effects of quenched disorder with long-range spatial correlations on the transport properties of an overdamped periodic ratchet are investigated. The modified Fourier-filtering method is applied to generate the long-range correlated spatial disorder with statistical properties eta(x)eta(x') approximately /x'-x/(-gamma), where gamma is the correlation exponent. Small amounts of this kind of quenched disorder are introduced in the equation of overdamped motion of a continuous time system, and the first two moments C1(t)=<x(t)> and C2(t)=<(x(t)-<x(t)>)(2) are calculated...

This article reports on methabenzthiazuron [1-(1,3-benzothiazol-2-yl)-1,3-dimethylurea] (MBT) adsorption process on six agricultural allophanic and nonallophanic soils. The effect of amendment with exogenous organic matter was also studied. Adsorption kinetic fits an hyperbolic model. MBT adsorption reached an apparent equilibrium within 2 h and followed a second-order reaction. The maximum adsorbed amounts for natural soils ranged from 32 to 145 microg g(-1). Rate constants were considered relatively low (0...

Difusse uterine myohipertrophy (DUMH) is a condition characterized by the presence of homogeneous and diffuse uterine enlargement in the absence of myoendometrial cause of bleeding. Today there is insufficient data to conclude that DUMH is a distinct clinicopathological entity. It is characterized by: 1) Uterine weight of more that 200 g, 2) a myometrial thickness of more that 2.0 cm and 3) the absence of any endomyometrial cause of bleeding. In DUMH the increased thickness of the myometrium is due to hypertrophy of the muscle cells with no increase in fibroconnective intersticial tissue and the bleeding secondary to increase endometrial area and abnormal myometrium contraction...

Previous studies showed that the in situ absorption of baclofen in rat jejunum was inhibited by beta-alanine, a nonessential amino acid, and therefore mediated, at least in part, by some beta-amino acid carrier. In this paper a similar study was undertaken using taurine, a sulfonic beta-amino acid, in order to evaluate its effect and to establish a general inhibition model. To achieve this goal, remaining concentrations of inhibitor were also measured and incorporated into the model. Previously, kinetic absorption in situ parameters for taurine in free solution were obtained: Vm = 27...

The contribution of the stomach and the small intestine to the in vivo absorption of fluoride from disodium and calcium monofluorophosphates was studied in comparison with that observed when sodium fluoride is given to rats. In vitro experiments with ligated duodena were also carried out. Fasted rats were given orally 50 micrograms of fluoride in pH 6.3 buffered disodium monofluorophosphate solutions with and without 50 mM added calcium. The same amount of fluoride was administered in the form of an aqueous sodium fluoride solution...

A 48 year old male scleroderma patient with typical impairment of respiratory function, including low vital capacity, low static lung compliance and low diffusing capacity for carbon monoxide, was treated with cyclofenil for one year. Assessment of lung function after 3, 6 and 12 months treatment showed marked improvement of vital capacity, increased physical working capacity, less hypoxia at maximum work, increase of static lung compliance and decreases of maximal transpulmonary pressure. Closing capacity decreased, and an increase in difussing capacity for carbon monoxide was seen...

The transport of L-proline, L-lysine and L-glutamate in rat red blood cells has been studied. L-proline and L-lysine uptake were Na(+)-independent. When the concentration dependence was studied both showed a non-saturable uptake assimilable to a difussion-like process, with high Kd values (0.718 and 0.191 min-1 for L-proline and L-lysine respectively). Rat red blood cells showed high impermeability to L-glutamate. No sodium dependence was observed and the Kd value was low (0.067 min-1). Our results show firstly, that rat red blood cells do not have amino acid transport systems for anionic and cationic amino acids and secondly that erythrocytes show no sodium-dependent L-proline transport, and that these cells are very permeable to this amino acid...

We have realized a statistic study about "Karyometric Index" in the hair cells of the Corti organ of the albino Wistar rat [correction of guinea pig] in thirty of these animals; after in vivo fixation. The Karyometric Index variations are a good indicator of the cellular basic functional activity. Therefore we tried to clarify if the their cells are or not resembling to other cellular types with the functional circadian circles as well as if they present it or not in their basic functionalism, as they are also included in the "Endocrine Difusse System" and the "Paraneuron" concepts...

The translational diffusion of the amphiphilic molecules in a number of lyotropic liquid crystalline phases has been measured with the pulsed NMR pulsed magnetic field gradient method. The amphiphiles studied were soaps, monoglycerids and lecithins. Measurements were performed both for oriented lamellar and for cubic phases. The order of magnitude of the diffusion coefficients was found to be the same as in neat liquids of analogous compounds. It was also found that the difussion coefficient depend markedly on the amphiphile end group in a way that parallels the area per polar head group as determined in X-ray studies...
