Recent updates and challenges on the regulation of precision medicine: The United States in perspective.

The rapid progress in "omics", such as genomics, metabolomics, microbiomics, has paved the path for precision medicine and revolutionized the development of drugs and devices promising to meet unmet medical needs. The aim of the present study was to investigate the current regulatory framework established by the United States Food and Drug Administration (USFDA) and to identify challenges and concerns through study of related literatures in the PubMed database. We found that efforts were made to facilitate the implementation of precision medicine through organizational reform, publication of guidance documents, and continuous post-market surveillance.

A century of oil and gas exploration in Albania: assessment of Naturally Occurring Radioactive Materials (NORMs).

The Naturally Occurring Radioactive Materials (NORMs) that are potentially generated from oil and gas extractions in Albania have been disposed of without regulations for many decades, and therefore, an extensive survey in one of the most productive regions (Vlora-Elbasan) was performed. A total of 52 gamma ray spectrometry measurements of soil, oil-sand, sludge, produced water and crude oil samples were performed. We discovered that relatively low activity concentrations of (226)Ra, (228)Ra, (228)Th and (40)K, with concentrations of 23±2Bq/kg, 23±2Bq/kg, 24±3Bq/kg and 549±12Bq/kg, respectively, came from the oil-sands produced by the hydrocarbon extraction of the molasses formations.

First characterisation of natural radioactivity in building materials manufactured in Albania.

This study focuses on the radiological characterisation of building materials manufactured in Albania by using a high-resolution gamma-ray spectrometer. The average activity concentrations of (40)K, (226)Ra and (232)Th were, respectively, 644.1±64.

A new FSA approach for in situ γ ray spectroscopy.

An increasing demand of environmental radioactivity monitoring comes both from the scientific community and from the society. This requires accurate, reliable and fast response preferably from portable radiation detectors. Thanks to recent improvements in the technology, γ spectroscopy with sodium iodide scintillators has been proved to be an excellent tool for in-situ measurements for the identification and quantitative determination of γ ray emitting radioisotopes, reducing time and costs.

Radiology turf wars and antitrust law.

Nonradiologist health care providers have enjoyed the privilege of film interpretation without the assistance of radiologists. However, encroachment on the radiologist's turf of radiological image interpretation by nonradiologist physicians and radiographer technicians is reminiscent of recent antitrust battles between anesthesiologists and nurse anesthetists. Numerous antitrust issues are relevant to radiology; however, the scope of this article is limited to antitrust issues most relevant to radiology turf battles.
