The failing heart is characterized by changes in gene expression. However, the regulatory regions of the genome that drive these gene expression changes have not been well defined in human hearts.
To define genome-wide enhancer and promoter use in heart failure, cap analysis of gene expression sequencing was applied to 3 healthy and 4 failed human hearts to identify promoter and enhancer regions used in left ventricles. Healthy hearts were derived from donors unused for transplantation and failed hearts were obtained as discarded tissue after transplantation.
Cap analysis of gene expression sequencing identified a combined potential for ≈23 000 promoters and ≈5000 enhancers active in human left ventricles. Of these, 17 000 promoters and 1800 enhancers had additional support for their regulatory function. Comparing promoter usage between healthy and failed hearts highlighted promoter shifts which altered aminoterminal protein sequences. Enhancer usage between healthy and failed hearts identified a majority of differentially used heart failure enhancers were intronic and primarily localized within the first intron, revealing this position as a common feature associated with tissue-specific gene expression changes in the heart.
This data set defines the dynamic genomic regulatory landscape underlying heart failure and serves as an important resource for understanding genetic contributions to cardiac dysfunction. Additionally, regulatory changes contributing to heart failure are attractive therapeutic targets for controlling ventricular remodeling and clinical progression.

The introduction of the corneal intrastromal titan ring by Krumeich intended to reduce the incidence of both complications. We present two patients with keratoconus who referred to our department after a PKP combined with the implantation of an intrastromal ring. The first patient suffered from bulbar pain and headaches. The second patient suffered from postoperative high myopia, irregular astigmatism and was contact lens intolerant. In the first patient we recognized anterior movement of the ring inside the stroma and decided to remove it. The second patient was found to have extreme bulging of the transplant. We removed the ring and sequentially performed a repeat-PKP. In both patients the implantation of the ring failed to decrease the postoperative astigmatism and caused symptoms that affected the patients' everyday life. RU.521 mw Therefore, we recommend not to use this titan ring.A new polyhydroxysteroid glycoside, regulusoside D (1), and a new polyhydroxylated steroid, (24S)-cholestane-3β,5,6β,8,15α,24-hexol (2), together with seven known compounds were purified from the starfish Pentaceraster regulus collected near Con Co Islands, Vietnam. The structure elucidation was confirmed by extensive analysis of their NMR and HR-QTOF mass experiments. Among isolated compounds, regulusoside D (1), (24S)-cholestane-3β,5,6β,8,15α,24-hexol (2), granulatoside A (4), 5α-cholestane-3β,6β,7α,15α,16β,26-hexol (6), 5α-cholestane-3β,6β,7α,8β,15α,16β,26-heptol (7) and 5α-cholestane-3β,6α,8,15α,16β,26-hexol (8) exhibited strong inhibitory effects on LPS-induced NO production in RAW264.7 cells with IC50 values of 9.13 ± 1.17, 9.19 ± 0.77, 8.63 ± 3.31, 12.61 ± 0.51, 14.83 ± 3.02 and 10.98 ± 1.22 µM, respectively.
The transition of new nurses into practice has been identified as challenging, and new nurses report having intentions to leave (ITL) jobs. Concerns of ITL are worrisome for the nursing profession, especially when faced with the need to replace an aging nursing workforce and to maintain quality patient care.
Guided by components of Meleis etal.'s mid-range transition theory, the purpose of this study was to test a theoretical model linking transition and ITL, as well as the personal, community and societal conditions of transition.
A predictive, non-experimental design using cross-sectional data was employed. Ontario registered nurses, who had graduated within two years, were randomly selected to complete a mailed questionnaire in 2015 (
 = 217). Structural equation modeling was undertaken to test the model.
The new nurses reported a relatively positive transition; yet, 44% of the respondents indicated leaving their first job, and 1% departed the nursing profession. A revised model of the constructs showed a more adequate fit with the data, but overall, the hypothesized model was not supported and methodological validity of tools questioned. From the modeling, lower role stress led to a positive transition.
Given organizational and governmental investments in orientation and transition programs, challenges in measuring transition and ITL requires additional research. Our findings highlight the value of organizations supporting new nurses by reducing role stress through reasonable workloads and expectations, which in turn contributes to a positive transition.

To review the efficacy, safety, and cost of 3 newly approved agents-ubrogepant, lasmiditan, and rimegepant-representing 2 therapeutic classes, calcitonin gene-related peptide (CGRP) receptor antagonist and serotonin 1F (5-HT
) agonists, for the acute treatment of migraine with or without aura.
The Institute of Health US National Library of Medicine Clinical Trials, PubMed, and Cochrane databases were queried. Abstracts, journal articles, and other relevant sources published or present were reviewed. Search terms included the following

Relevant English-language articles from June 30, 2010, to August 31, 2020, were evaluated and included in the narrative.
CGRP receptor antagonists, ubrogepant and rimegepant, achieved 2-hour pain freedom and freedom from the most bothersome migraine symptom (MBS) at 2 hours. Both agents were well tolerated, with adverse effects similar to placebo. Lasmiditan, a 5-HT
receptor antagonist, also improved 2-hour pain freedom and freedom from the MBS at 2 hours. Lasmiditan is associated with dizziness, paresthesia, somnolence, nausea, fatigue, and lethargy.
