Human breast cancer cells (MCF-7, maintained in long-term culture) contain separate estrogen receptors specific for either 17/î-estradiol or estrone. Utilizing optimum conditions for the protamine sulfate assay, it has been possible to demonstrate both receptors in the 0.6 M KCI extract of nuclei and in the cytosol. Similarly, in the exchange assay, high-affinity lowcapacity binding sites for ...

Increased stool losses of water, solute, and organic acids after the ingestion of milk during acute diarrhea of infancy have been related to impaired absorption of carbohydrate (1). We have observed that the osmolality of diarrheal stool water is usually high during periods of milk intake. Furthermore, we have demonstrated that carbohydrate comprises most of the solute content of the stool wate...

This rise was driven largely by a dramatic increase in cases involving " youth‐produced " sexual images – pictures taken by minors, usually of themselves, which met legal definitions of child pornography. In most of these cases, an adult offender who solicited images from a minor was the person arrested. Reflecting this trend, there were also in‐ creases in the proportion of adolescent victims ...

Causes of death in pediatric systemic lupus erythematosus Sirs, Pediatric systemic lupus erythematosus (pSLE) remains a severe disease although its prognosis has improved with time. Use of new therapies may result in modifying the causes of mortality. Death was mostly due to renal insufficiency and infections (1-4) during the 1980-1990 decade, while no death was recorded in the sole study enrol...

in this paper, a numerical solution of an inverse non-dimensional heat conduction problem by spline method will be considered. the given heat conduction equation, the boundary condition, and the initial condition are presented in a dimensionless form. a set of temperature measurements at a single sensor location inside the heat conduction body is required. the result show that the proposed meth...

we introduce and discuss the homotopy perturbation method, the adomian decomposition method and the variational iteration method for solving the stefan problem with kinetics. then, we give an example of the stefan problem with  kinetics and solve it by these methods.

in this paper, a boussinesq equation is solved by using the adomian's decomposition method, modified adomian's decomposition method and homotopy analysis method. the approximate solution of this equation is calculated in the form of series which its components are computed by applying a recursive relation. the existence and uniqueness of the solution and the convergence of the propose...

in a strapdown magnetic compass, heading angle is estimated using the earth's magnetic field measured by three-axis magnetometers (tam). however, due to several inevitable errors in the magnetic system, such as sensitivity errors, non-orthogonal and misalignment errors, hard iron and soft iron errors, measurement noises and local magnetic fields, there are large error between the magnetometers'...

in this research three-dimensional free vibration analysis of functionally graded circular plate with various boundary conditions is achieved. a semi-analytical method, which makes use of the state space method and the one-dimensional differential quadrature method, is used to obtain the vibration frequencies and dynamic responses of circular plates. numerical results are given to demonstrate t...
