It is unknown whether intracranial atherosclerotic disease (ICAD), in addition to causing stenosis, also associates with abnormal arterial enlargement, a condition known as intracranial dolichoectasia (IDE). Across symptomatic ICAD patients, we aim to determine IDE prevalence and IDE impact on cerebral hemodynamics and recurrent cerebral ischemia.
We analyzed 98 participants (mean age 63.8
±
11.9 years, 56.1% men) of the prospective observational study MYRIAD. Participants were enrolled within 21 days of an ischemic stroke or transient ischemic attack caused by moderate-to-severe ICAD. Semi-automatic vessel segmentation was used to determine diameters, length, and tortuosity-index of proximal intracranial arteries. Either ectasia (increased diameter) or dolichosis (increased length or TI) defined IDE. We assessed IDE association with new infarcts during 12-month follow-up, and IDE correlation with cerebral hemodynamics determined by quantitative MR-angiography (QMRA), MR-perfusion weighted-iacross the stenotic artery, suggesting that IDE may originate as an adaptive mechanism in ICAD.
Direct binding of rumenic acid to the cardiac myosin-2 motor domain increases the release rate for orthophosphate and increases the Ca
responsiveness of cardiac muscle at low load. Physiological cellular concentrations of rumenic acid affect the ATP turnover rates of the super-relaxed and disordered relaxed states of β-cardiac myosin, leading to a net increase in myocardial metabolic load. In Ca
-activated trabeculae, rumenic acid exerts a direct inhibitory effect on the force-generating mechanism without affecting the number of force-generating motors. In the presence of saturating actin concentrations rumenic acid binds to the β-cardiac myosin-2 motor domain with an EC
of 200nM. Molecular docking studies provide information about the binding site, the mode of binding, and associated allosteric communication pathways. Free rumenic acid may exceed thresholds in cardiomyocytes above which contractile efficiency is reduced and interference with small molecule therapeutics, targeting cardiac myosin, occunduces a different mode of rumenic acid binding in the case of non-muscle myosin-2C and blocks binding to skeletal muscle and smooth muscle myosin-2 isoforms.Zona pellucida (ZP)-bound spermatozoa have normal morphology and motility and can enhance the ICSI outcomes. Selection of zona pellucida-bound spermatozoa is recently considered to find functional spermatozoa for ICSI. This study reviewed the efficacy of ZP-bound sperm selection on the ICSI outcomes includes fertilisation rate, embryo quality, embryo transfer rate and clinical pregnancy rate. The databases searched include PubMed, Scopus and Cochrane databases up to January 2019. All research reports with full text and in English language that addressing the relation between ZP-sperm selection and ICSI outcomes were included. Fifty studies were suitable after screening of the 845 identified articles. After exclusions, five of these studies were included. SQ22536 order Meta-analytic pooling of data indicated no association between the ICSI outcomes and ZP-bound sperm selection except a marginal effect on implantation rate. Eliminating one study indicated that ZP-bound sperm selection technique improves embryo quality, implantation rate and clinical pregnancy rate. This study revealed that ZP-bound sperm selection produces only a slight improvement in implantation rate. However, further studies with a large number of couples must be done to clarify the potential beneficial effect of ZP-bound spermatozoa on ICSI outcomes.
Young people with neurodisability experience lower levels of mental wellbeing and are at increased risk of mental illness compared with their non-disabled peers. Social participation is recognized as a protective factor against mental illness and a potential pathway to support better mental wellbeing in neurodisability.
This co-design study involved young people, parents and clinicians. First, possible interventions were identified through a rapid systematic evidence review. Any study designs were considered, which included people with a neurodisability aged 0-18 years, which evaluated a therapy intervention with social participation and mental health outcomes. Titles and abstracts were screened by two reviewers, from the included studies data were extracted and then presented using written summaries. Second, the summaries were discussed and prioritized in stakeholder groups with young people, parents and clinicians. Groups were audio recorded and framework analysis was used to identify and specify interventified core elements of social participation interventions that may improve mental health outcomes in young people with neurodisability, which should now be tested.
Maintaining a healthy living after the end of a lifestyle intervention is a challenge for persons with severe obesity. Measurable outcomes are often emphasised, but there is a need for understanding the process of lifestyle change and the long-term perspectives among persons with severe obesity.
To describe and deepen the understanding of how persons with severe obesity experience making and maintaining lifestyle changes in everyday life three years after lifestyle intervention.
The study used a hermeneutic phenomenological approach. A purposive sample of seven adults with BMI≥40 was recruited from a lifestyle intervention programme. Data were generated through individual follow-up interviews. The analysis was based on theoretical framework on dwelling and mobility. Ethical approvals were received from the Danish Data Protection Agency and the ethical principles of the Declaration of Helsinki were followed.
One overarching theme emerged 'The journey of ups and downs'. Three sub-themes were 'Living with and tackling the demands of life's hassles', 'Deliberating the fight for weight loss' and 'Needing a trusted person to feel met as a human being'.
Everyday life among persons with severe obesity is experienced as a dynamic process of shifting experiences of dwelling and mobility. Sustained lifestyle changes require ongoing adjustments of action, which healthcare providers can influence in ways that either support or obstruct. Collaboration and a humanised approach across disciplines and sectors are suggested to promote sustained healthy living.
