A PERTURBATION CELL ATLAS OF HUMAN INDUCED PLURIPOTENT STEM CELLS.

Towards comprehensively investigating the genotype-phenotype relationships governing the human pluripotent stem cell state, we generated an expressed genome-scale CRISPRi Perturbation Cell Atlas in KOLF2.1J human induced pluripotent stem cells (hiPSCs) mapping transcriptional and fitness phenotypes associated with 11,739 targeted genes. Using the transcriptional phenotypes, we created a minimum distortion embedding map of the pluripotent state, demonstrating rich recapitulation of protein complexes, such as strong co-clustering of MRPL, BAF, SAGA, and Ragulator family members.

A systematic review and meta-analysis of attentional bias toward food in individuals with overweight and obesity.

Attentional bias to food stimuli may contribute to the etiology and/or maintenance of overweight and obesity. We conducted a literature review and meta-analysis per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to identify the effect size associated with attentional bias to palatable food in persons with overweight/obesity across the age spectrum. Included studies measured attentional bias to food stimuli using two reaction-time tasks (dot-probe, emotional Stroop), eye-tracking methodology, and/or event-related potentials.

Using outcomes data to justify instituting new technology: a single institution's experience.

Background: The PILLAR II trial demonstrated PINPOINT is safe, feasible to use with no reported adverse events and resulted in no anastomotic leaks in patients who had a change in surgical plan based on PINPOINT's intraoperative assessment of tissue perfusion during colorectal resection. Whether the cost savings associated with this reduction in anastomotic complications can offset the cost of investing in PINPOINT is unknown.

Methods: We performed a retrospective analysis of all patients (N = 347) undergoing colectomy with primary anastomosis from January 2015 to April 2016.

A precise measurement of the magnetic field in the corona of the black hole binary V404 Cygni.

Observations of binary stars containing an accreting black hole or neutron star often show x-ray emission extending to high energies (>10 kilo--electron volts), which is ascribed to an accretion disk corona of energetic particles akin to those seen in the solar corona. Despite their ubiquity, the physical conditions in accretion disk coronae remain poorly constrained. Using simultaneous infrared, optical, x-ray, and radio observations of the Galactic black hole system V404 Cygni, showing a rapid synchrotron cooling event in its 2015 outburst, we present a precise 461 ± 12 gauss magnetic field measurement in the corona.
