Tumor-induced osteomalacia (also known as oncogenic osteomalacia) is a rare disorder characterized by phosphaturia, hypophosphatemia, and osteomalacia mimicking the clinical phenotype of either X-linked or autosomal dominant hereditary hypophosphatemic rickets. Tumor-induced osteomalacia develops because of tumors that are predominantly of benign mesenchymal origin but that may occasionally be malignant. Surgical removal of the tumor relieves all symptoms. Hemangiopericytoma is the most dominant histologic entity in tumor-induced osteomalacia.
PNETs are aggressive embryologic tumors with a poor prognosis and are divided in central and peripheral types. Although peripheral PNETs spread early to bones, lymph nodes, lung and liver, a leptomeningeal spread, as in this case, is extremely rare.

A new program was launched on Radiolopolis: "Dare To Share!". Dare To Share! is a project, which allows sharing cases between researchers and colleagues. Users may find interesting or needed cases/images for different kind of projects (studies, books, publications, presentations etc.) while assuring the owner's credentials/copyright of the case. Direct contact between the searcher and the owner of the case provides also a good opportunity to get to know new, potential partners for future projects.
More infos about the Dare To Share! program can be found here.
Viruses are infectious agents that can cause epidemics and pandemics. The understanding of virus formation, evolution, stability, and interaction with host cells is of great importance to the scientific community and public health. Typically, a virus complex in association with its aquatic environment poses a fabulous challenge to theoretical description and prediction. In this work, we propose a differential geometry-based multiscale paradigm to model complex biomolecule systems. In our approach, the differential geometry theory of surfaces and geometric measure theory are employed as a natural means to couple the macroscopic continuum domain of the fluid mechanical description of the aquatic environment from the microscopic discrete domain of the atomistic description of the biomolecule....

Over the past decade, teleradiology has become a well-established practice in Europe. But without homogenous EU legislation, experts are concerned about possible clinical risks. Radiologists and an EU representative compared advantages and warned of legal and medical risks during a joint session of the European Society of Radiology and European Commission held Saturday, March 6.

The West Virginia House Health and Human Resources Committee on Friday held a public hearing in consideration of a bill (SB 597) that would require doctors to offer women seeking abortions the opportunity to view an ultrasound image of the fetus if an ultrasound is considered the standard of care, the AP/Charleston Daily Mail reports...

New research published in today's issue of the Archives of Internal Medicine (Vol. 170, No. 5), by an investigator at The Cancer Institute of New Jersey (CINJ) and colleagues at Memorial Sloan-Kettering Cancer Center in New York, shows that the type of specialist that men with localized prostate cancer see can influence the form of therapy they ultimately receive...

To improve the assessment of magnetic field exposures for occupational health studies, the Multiwave® System III (MW3) was developed to capture personal exposures to the three-dimensional magnetic field vector B(t) in the 0-3000 Hz band. To process hundreds of full-shift MW3 measurements from epidemiologic studies, new computer programs were developed to calculate the magnetic field's physical properties and its interaction with biological systems through various mechanisms (magnetic induction, radical pair interactions, ion resonance, etc.). For automated calculations in the frequency domain, the software uses new algorithms that remove artifacts in the magnetic field's Fourier transform due to electronic noise and the person's motion through perturbations in the geomagnetic field from s...
Lipids form the structural and functional basis of biological membranes, and methods for studying their self-organization in well-defined nano- and micro-scale model systems can provide insights into biology. Using lipids as an ink for dip-pen nanolithography (lipid DPN) permits the rapid nanostructuring of multicomponent model lipid membrane systems, but this technique has so far been limited to air. Here we demonstrate that lipid DPN can be carried out under water with single tips or parallel arrays. Using the same tip for deposition and imaging in aqueous solution permits imaging of self-spreading lipid bilayer spots in situ and quantification of the nanoscale spreading kinetics in real time by means of lateral-force microscopy. Furthermore, using fluorophore-labeled phospholipids, we d...
