  1. Stem Cell Cloning

    [ November 18, 2014 ]

    Last year, scientists succeeded in cloning human embryonic stem cells (hESC) that may aid in developing replacement tissue to treat serious and fatal diseases and even create cloned babies in the future. Stem cells are biological cells that have the ability to develop into many different types of specialized cells during early life and growth. In addition, they serve as an internal repair system in certain tissues, infinitely dividing as long as the organism is still alive. When a stem cell divides, each new cell has the potential to either remain a stem cell or become another type of cell with a more specialized function, such as a neuron, a red blood cell, or a brain cell. In some organs, such ...

  2. Effect of nontuberculous mycobacteria on lung function in patients with cystic fibrosis

    [ November 18, 2014 ]

    There has been much debate about whether to treat airway colonization with nontuberculous mycobacteria (NTM) in patients with cystic fibrosis (CF). The rationale for therapy is based upon an association between NTM colonization and severity of CF. However, while patients with CF are at an increased risk of colonization with NTM, it is unknown if NTM contributes to decreasing lung function. This study retrospectively evaluated whether NTM colonization in adult patients with CF is associated with impairment of lung function. In addition, the effect of cystic fibrosis related diabetes (CFRD), and gastro-esophageal reflux disease (GERD) on NTM colonization was evaluated. Data from adult CF patients enrolled in the Gunnar Esiason Adult Cystic Fibrosis Lung Program at Columbia UniversityMedical Center in ...

  3. Genome Sequencing

    [ May 23, 2014 ]

    In response to recent advances in genome sequencing, over 700,000 Americans have had their genomes sequenced. This technology allows people who have or will later develop life-threatening illnesses to receive the best treatment possible. Many people remain skeptical of this test even though it provides a multitude of health benefits and is increasingly affordable. Despite advances in technology and decreases in the cost, many are still hesitant to have their genome sequenced. This reluctance stems from an omission in the Genetic Information Nondiscrimination Act (GINA), a law created in 2008 that protects individuals’ right to conceal genetic information from employers and health insurers. The law omitted the right to confidentiality from life, disability, and long-term healthcare providers. This is an omission ...
