Binning microbial genomes using deep learning

By |2018-12-12T20:59:43+00:00December 12th, 2018|

Abstract Identification and reconstruction of microbial species from metagenomics wide genome sequencing data is an important and challenging task. Current existing approaches rely on gene or contig co-abundance information across multiple samples and k-mer composition information in the sequences. Here we use recent advances in deep learning to develop an algorithm that uses variational autoencoders [...]

What’s holding pharma back from the next antibiotic breakthrough?

By |2018-12-12T19:35:33+00:00December 12th, 2018|

By PETER BAK DECEMBER 10, 2018 In the five years since the alarm sounded about so-called superbugs, the world has continued to grapple with the staggering health and economic impacts of antibiotic resistance and mounting resistance to antibiotics of last resort. In the U.S. alone, antibiotic resistance adds $20 billion to $35 billion in direct health care costs each year, along with [...]

Life in Deep Earth Totals 15 to 23 Billion Tonnes of Carbon—Hundreds of Times More than Humans

By |2018-12-12T19:21:43+00:00December 12th, 2018|

Barely living "zombie" bacteria and other forms of life constitute an immense amount of carbon deep within Earth's subsurface—245 to 385 times greater than the carbon mass of all humans on the surface, according to scientists nearing the end of a 10-year international collaboration to reveal Earth's innermost secrets. 10 DECEMBER 2018 Contacts Terry Collins, [...]

Breast cancer risk after childbirth may persist more than 20 years

By |2018-12-12T18:32:10+00:00December 12th, 2018|

The increased risk for breast cancer after giving birth can last for around 24 years, according to findings published in Annals of Internal Medicine. “Parity is widely recognized as protective for breast cancer, but breast cancer risk may be increased shortly after childbirth,” Hazel B. Nichols, PhD, assistant professor in the department of epidemiology at the University of North Carolina [...]

Chronic obstructive pulmonary disease mortality, a competing risk analysis

By |2018-12-12T18:11:31+00:00December 12th, 2018|

Abstract Background Current risk factors for Chronic Obstructive Pulmonary Disease mortality focus only on overall and respiratory death. We investigated whether risk factors for each specific cause of mortality are different depending on the outcome under consideration. Methods This retrospective cohort study included patients with a clinical diagnosis of COPD, older than 40, greater than [...]

Severe bronchiolitis profiles and risk of recurrent wheeze by age 3 years

By |2018-12-12T18:02:49+00:00December 12th, 2018|

Background A better understanding of bronchiolitis heterogeneity might help clarify its relationship with the development of recurrent wheezing and asthma. Objectives We sought to identify severe bronchiolitis profiles using a clustering approach and to investigate for the first time their association with allergy/inflammatory biomarkers, nasopharyngeal microbiota, and development of recurrent wheezing by age 3 years. Methods [...]

COPD increases cardiac mortality in patients presenting with ventricular tachyarrhythmias and aborted cardiac arrest

By |2018-12-12T17:52:41+00:00December 12th, 2018|

Highlights COPD increases mortality in patients with ventricular tachyarrhythmias and SCA. COPD was associated with the primary endpoint of long-term all-cause mortality. Results showed consistency in multivariable regression and propensity score matching. COPD was associated with secondary endpoints such as cardiac death at 24 h. Abstract Objectives The study sought to assess the prognostic impact of [...]

Ebola spreads to major Congo city as vaccines a concern
