Credit: Gabriel Chamie Universal HIV testing with linkage to treatment and prevention may be a promising approach to accelerate reductions in new infections in generalized epidemic settings, according to a study published February 9th, 2021 in the open-access journal PLOS Medicine by Catherine Koss of the University of California, San Francisco, and colleagues. Despite major gains in HIV testing and treatment, in 2019 there were 1.7 million new HIV infections, of which nearly 60% occurred in sub-Saharan Africa. Daily oral pre-exposure prophylaxis (PrEP) with tenofovir disoproxil fumarate/emt...

2 fertilization effects on vegetation photosynthesis,” there was a small error in the histogram in Fig. 1B in the main text and in fig. S9B in the supplementary materials caused by a data-processing bug (the x axis started from 0.2, not from zero as labeled), and the calculation of standard deviation (SD) was not fully explained in the figure caption (the caption did not state that the SD was calculated from the data within the range of the y axis). Figure 1B, fig. S9B, and their captions have been corrected accordingly. In the original figure, the authors chose the β range of −10 to 5...

The resulting excessive... view more  Credit: National Institutes for Quantum and Radiological Science and Technology. Oxygen is essential for human life, but within the body, certain biological environmental conditions can transform oxygen into aggressively reactive molecules called reactive oxygen species (ROS), which can damage DNA, RNA, and proteins. Normally, the body relies on molecules ca...

In the supplementary materials file for the Research Article “[Identification of Integrator-PP2A complex (INTAC), an RNA polymerase II phosphatase][1],” Western blotting with PP2A-C antibody in fig. S7C (third row) was mistakenly placed during manuscript preparation by the authors. The corrected fig. S7C has been updated in the corrected version of the supplementary materials file. The conclusion of fig. S7C is that INTS11 shRNAs efficiently reduce the protein levels of INTS11 but not INTS8 or PP2A-C. Therefore, this correction does not affect any of the conclusions drawn in the paper. [1...
