Caregiver-assisted coping skills training for patients with COPD: background, design, and methodological issues for the INSPIRE-II study

Chronic Obstructive Pulmonary Disease (COPD) is a progressive illness characterized by airflow obstruction and dyspnea that afflicts over 12 million people and represents a leading cause of death in the United States. Not surprisingly, COPD is often associated with emotional distress and reduced psychosocial adjustment, which can negatively impact physical functioning and impair quality of life. However, the psychosocial consequences of COPD remain largely untreated. A previous randomized trial from our research team demonstrated that coping skills training (CST) can improve pulmonary-specific quality of life among pulmonary patients awaiting lung transplant (the INSPIRE study). To date, however, no studies have examined the effects of a caregiver-assisted CST intervention in patients with COPD with less severe disease

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

Biotinylation of Membrane Proteins for Binder Selections

The selective immobilization of proteins represents an essential step in the selection of binding proteins such as antibodies. The immobilization strategy determines how the target protein is presented to the binders and thereby directly affects the experimental outcome. This poses specific challenges for membrane proteins due to their inherent lack of stability and limited exposed hydrophilic surfaces. Here we detail methodologies for the selective immobilization of membrane proteins based on the strong biotin-avidin interaction and with a specific focus on its application for the selection of nanobodies and sybodies. We discuss the challenges in generating and benefits of obtaining an equimolar biotin to target-protein ratio
