Musculoskeletal ultrasound has seen a considerable surge in usage in recent years. Its advantages are manifold. Given adequate training of the examiner, it is very cost-effective; there is no ionizing radiation to contend with; the scanners are normally highly portable; and it enables certain interventional procedures to be performed with great accuracy (therapeutic injections of local anesthetics and/or corticosteroids into areas of complex anatomy, e.g., the shoulder).
With the latest release of their definitive full-text resource for synthetic organic chemistry, Science of Synthesis (SOS), Thieme has added a total of 1,378 printed pages of new content. SOS 4.9 includes knowledge updates on the synthesis of pyrazoles and enol ethers as well as on the application of the Mannich reaction in synthesis. The new Reference Library volume focuses on catalytic oxidation in organic synthesis.
Ever since the International Human Genome Project achieved its extraordinary goal of sequencing and mapping the entire human genome, represented by approximately 3 billion base pairs, with its far-reaching implications for understanding the causes of human genetic disorders and their diagnosis, progress in the field has not slowed down.
Lung cancer is the leading cause of cancer-related death among men and women in the U.S. and worldwide. For many decades, lung cancer was the sole cancer among the deadly four without an evidence-based screening method for decreasing mortality. This changed in November 2011, when findings from the National Lung Cancer Screening Trial showed low-dose lung CT screening was more efficacious in reducing deaths in high-risk individuals than conventional radiography. As such, an ever-increasing number of health organizations now recommend this screening protocol.
