News at a glance: Muscular dystrophy therapy, lab-grown chicken, and humans ’ toll on wildlife
BIOMEDICINE Muscular dystrophy therapy approved The U.S. Food and Drug Administration has approved the first gene therapy for Duchenne muscular dystrophy (DMD), a genetic disease that cripples boys and usually results in death by age 30. The treatment from Sarepta Therapeutics introduces a short version of the gene for dystrophin, a crucial muscle protein, which is mutated in patients with DMD. A one-time intravenous infusion of a virus delivers the functioning “microdystrophin” gene into patients’ muscle cells. The 22 June approval is only for boys 4 to 5 years old, a group that appeared likely to ben...

Study unravels antibiotic resistance in MRSA ‘superbug’ infections
FINDINGSResearchers applied a new approach pioneered at UCLA to predict whichmethicillin-resistant Staphylococcus aureus, or MRSA,infections willfail to respond toantibiotic treatment. By focusing on epigenetics — changes to gene expression that can’t be detected by standard DNA sequencing — the study examined how the immune system recognizes dangerous superbugs and works with antibiotics to clear them.BACKGROUNDThe Staphylococcus aureus bacterium can  live harmlessly on a person’s skin and in their nose, occasionally causing mild infections that can be treated with standard antibiotics. When itentersthe bloodstre...

What Are Potential Complications of Tattooing?
Discussion “Tattooing of skin via deposition of pigment particles and ink ingredients in the dermis changes normal skin into abnormal skin. Fortunately, this often causes no harm and no disease, although with important exceptions.” Tattoos can be inadvertent from road dirt, gunpowder, pencil graphite etc., but most are desired. Tattoos are common in many cultures and over time..They have been increasing in popularity in the United States over the past few years particularly with a younger, wider and more diverse population. Newsweek reported an 18-country study in 2018 which showed 46% of Americans have a tat...

Expanding Research Capacity in Sub-Saharan Africa Through Informatics, Bioinformatics, and Data Science Training Programs in Mali
Conclusion Bioinformatics and data science training programs in developing countries necessitate incremental and collaborative strategies for their feasible and sustainable development. The progress described here covered decades of collaborative efforts centered on training and research on computationally intensive topics. These efforts laid the groundwork and platforms conducive for hosting a bioinformatics and data science training program in Mali. Training programs are perhaps best facilitated through Africa’s university systems as they are perhaps best positioned to maintain core resources during lapses in sho...

Perceptions of Severe Asthma and Asthma-COPD Overlap Syndrome Among Specialists: A Questionnaire Survey.
CONCLUSIONS: Specialists had diverse perceptions and clinical practices regarding severe asthma and ACOS patients. This heterogeneity must be considered in future studies and strategy development for severe asthma and ACOS. PMID: 29676069 [PubMed]

Maternal Exposure of BALB/c Mice to Indoor NO2 and Allergic Asthma Syndrome in Offspring at Adulthood with Evaluation of DNA Methylation Associated Th2 Polarization
Conclusions: Maternal exposure to indoor environmental NO2 causes allergic asthma-related consequences in offspring absent any subsequent lung provocation and potentiates the symptoms of allergic asthma in adult offspring following postnatal allergic sensitization and challenge; this response is associated with the Th2-based immune response and DNA methylation of the IL4 gene. https://doi.org/10.1289/EHP685 Received: 19 June 2016 Revised: 07 June 2017 Accepted: 19 June 2017 Published: 13 September 2017 Address correspondence to N.
