Phenotypes Associated with 16p11.2 Copy Number Gains and Losses at a Single Institution.

Chromosome 16p11.2 is one of the susceptible sites for recurrent copy number variations (CNVs) due to flanking near-identical segmental duplications. Five segmental duplications, named breakpoints 1 to 5 (BP1-BP5), have been defined as recombination hotspots within 16p11.

Radiographic assessment of sarcopenia in the trauma setting: a systematic review.

Background: Compared with similarly injured patients of a younger age, elderly patients have worse outcomes from acute injury. One factor adversely affecting outcomes is sarcopenia, which has been assessed in healthy elderly populations through established clinical and radiological criteria. However, in the acute care setting, no such criteria have been established.

Human brain metastatic stroma attracts breast cancer cells via chemokines CXCL16 and CXCL12.

The tumor microenvironment is composed of heterogeneous populations of cells, including cancer, immune, and stromal cells. Progression of tumor growth and initiation of metastasis is critically dependent on the reciprocal interactions between cancer cells and stroma. Through RNA-Seq and protein analyses, we found that cancer-associated fibroblasts derived from human breast cancer brain metastasis express significantly higher levels of chemokines CXCL12 and CXCL16 than fibroblasts from primary breast tumors or normal breast.

Pyrobaculum igneiluti sp. nov., a novel anaerobic hyperthermophilic archaeon that reduces thiosulfate and ferric iron.

A novel anaerobic, hyperthermophilic archaeon was isolated from a mud volcano in the Salton Sea geothermal system in southern California, USA. The isolate, named strain 521T, grew optimally at 90 °C, at pH 5.5-7.

Bayesian clinical trials in action.

Although the frequentist paradigm has been the predominant approach to clinical trial design since the 1940s, it has several notable limitations. Advancements in computational algorithms and computer hardware have greatly enhanced the alternative Bayesian paradigm. Compared with its frequentist counterpart, the Bayesian framework has several unique advantages, and its incorporation into clinical trial design is occurring more frequently.

Vandetanib for the treatment of lung cancer.

Introduction: VEGF and EGFR are validated pathways for targeted therapy in non-small cell lung cancer (NSCLC). Once considered to be separate targets, VEGF and EGFR are now shown to have interconnected downstream pathways, potentiating the effectiveness of their dual signaling inhibition in cancer therapy. Molecules such as vandetanib that inhibit VEGFR and EGFR have also been reported to inhibit other receptors, including RET and additional kinases, and may be beneficial in treating patients with solid tumors.
