Transcriptional fidelity depends on accurate promoter selection and initiation from the correct sites. In yeast, H3K36me3-mediated recruitment of the Rpd3S HDAC complex to gene bodies suppresses spurious transcription initiation. Here we describe an equivalent pathway in metazoans. PWWP2A/B is an H3K36me3 reader that forms a stable complex with HDAC1/2. We used CAGE-seq to profile all transcription initiation sites in wild-type mESCs and cells lacking PWWP2A/B. Oxaliplatin price Loss of PWWP2A/B enhances spurious initiation from intragenic sites present in wild-type mESCs, and this effect is associated with increased levels of initiating Pol-II and histone acetylation. Spurious initiation events in Pwwp2a/b DKO mESCs do not overlap in genomic location or chromatin features with spurious sites that arise in Dnmt3b KO mESCs, previously reported to function in the suppression of intragenic transcriptional initiation, suggesting these pathways function cooperatively in maintaining the fidelity of transcription initiation in metazoans.In contrast to enormous progresses in electrode active materials, little attention has been paid to electrode sheets despite their crucial influence on practical battery performances. Here, as a facile strategy to address this issue, we demonstrate nanofibrous conductive electrode binders based on deoxyribonucleic acid (DNA)-wrapped single-walled carbon nanotubes (SWCNT) (denoted as DNA@SWCNT). DNA@SWCNT binder allows the removal of conventional polymeric binders and carbon powder additives in electrodes. As a proof of concept, high-capacity overlithiated layered oxide (OLO) is chosen as a model electrode active material. Driven by nanofibrous structure and DNA-mediated chemical functionalities, the DNA@SWCNT binder enables improvements in the redox reaction kinetics, adhesion with metallic foil current collectors, and chelation of heavy metal ions dissolved from OLO. The resulting OLO cathode exhibits a fast charging capability (relative capacity ratio after 15 min [versus 10 h] of charging = 83%), long cyclability (capacity retention = 98% after 700 cycles), and thermal stability.Aureochromes represent a unique type of blue light photoreceptors that possess a blue light sensing flavin-binding LOV-domain and a DNA-binding bZIP domain, thus being light-driven transcription factors. The diatom Phaeodactylum tricornutum, a member of the essential marine primary producers, possesses four aureochromes (PtAUREO1a, 1b, 1c, 2). Here we show a dramatic change in the global gene expression pattern of P. tricornutum wild-type cells after a shift from red to blue light. About 75% of the genes show significantly changed transcript levels already after 10 and 60 min of blue light exposure, which includes genes of major transcription factors as well as other photoreceptors. Very surprisingly, this light-induced regulation of gene expression is almost completely inhibited in independent PtAureo1a knockout lines. Such a massive and fast transcriptional change depending on one single photoreceptor is so far unprecedented. We conclude that PtAUREO1a plays a key role in diatoms upon blue light exposure.Glia, the helper cells of the brain, are essential in maintaining neural resilience across time and varying challenges By reacting to changes in neuronal health glia carefully balance repair or disposal of injured neurons. Malfunction of these interactions is implicated in many neurodegenerative diseases. We present a reductionist model that mimics repair-or-dispose decisions to generate a hypothesis for the cause of disease onset. The model assumes four tissue states healthy and challenged tissue, primed tissue at risk of acute damage propagation, and chronic neurodegeneration. We discuss analogies to progression stages observed in the most common neurodegenerative conditions and to experimental observations of cellular signaling pathways of glia-neuron crosstalk. The model suggests that the onset of neurodegeneration can result as a compromise between two conflicting goals short-term resilience to stressors versus long-term prevention of tissue damage.
To assess the impact of MRI findings on management of symptomatic patients following RFA of OO.
Retrospective review of 43 patients with RFA for OO between June 2010 and June 2017 was performed. Patient, nidus and ablation data were reviewed. Pre- and 6-8 weeks post-procedural MRI (n=32) were compared for coverage of nidus by ablation zone, bone marrow edema, nidus hyperintensity and other findings. Baseline pain levels and analgesic use were compared with post-procedural follow-up visit at 6-8 weeks. Three groups of clinical and MRI outcomes of complete (CR), partial (PR) and no response (NR) were defined. A weighted-kappa statistic was used to assess for agreement.
Clinical responses were CR in 34/43 (79.1%, 95%CI 64.0-90.0%), PR in 8/43 (18.6%) and NR in 1/43 (2.3%) patients. All 19/32 patients with MRI CR experienced clinical CR. One patient with MRI NR had clinical NR. All 7/32 patients with clinical PR had MRI PR. All 4/43 complications were in MRI PR or NR groups. Substantial agreement was observed between MRI and clinical outcomes (kappa0.69, 95%CI0.45-0.95). MRI helped determine etiologies in all symptomatic patients and their management (n=8).
MRI is recommended for symptomatic patients after ablation.

Infection by SARS-CoV-2 (COVID-19) can range from asymptomatic to life-threatening multi-system disease. Heart involvement most commonly occurs during severe COVID-19 infection. Myocardial injury, based on elevated levels of myocardial enzymes, has been noted in up to 30% of patients with COVID-19 infection and could be a marker for worse prognosis. A few cases of possible myocarditis due to SARS-CoV-2 have been described, providing variable degree of evidence of direct myocardial involvement. We reviewed in detail those cases in comparison to relevant literature on SARS and MERS and attempted to draw initial conclusions in regard to clinical presentation, treatment and prognosis.
