<h3>Abstract</h3> Nuclei within cells are constantly subjected to compressive, tensile and shear forces, which regulate nucleoskeletal cytoskeletal remodeling, activate signaling pathways direct cell-fate decisions. Multiple rheological methods have been adapted for characterizing the response applied forces of isolated nuclei intact cells. However, <i>in vitro</i> measurements fail capture viscoelastic modulation nuclear stress-strain relationships by physiological tethering surrounding...

Summary Loss of microbial diversity is considered a major threat because its importance for ecosystem functions, but there lack conclusive evidence that itself reduced under anthropogenic stress, and about the consequences loss. Heavy metals are one largest, widespread pollutant types globally, these represent significant environmental stressor terrestrial communities. Using combined metagenomics functional assays, we show compositional response communities to long‐term heavy metal stress...

To quantify the hospital burden and health economic impact of idiopathic intracranial hypertension.Hospital Episode Statistics (HES) national data was extracted between 1st January 2002 31st December 2016. All those within England with a diagnosis hypertension were included. Those secondary causes raised pressure such as tumours, hydrocephalus cerebral venous sinus thrombosis excluded.A total 23,182 new IIH cases diagnosed. Fifty-two percent resided in most socially deprived areas (quintiles...

<h3>Importance</h3> Idiopathic intracranial hypertension (IIH) causes headaches, vision loss, and reduced quality of life. Sustained weight loss among patients with IIH is necessary to modify the disease prevent relapse. <h3>Objective</h3> To compare effectiveness bariatric surgery that a community management (CWM) intervention for treatment active IIH. <h3>Design, Setting, Participants</h3> This 5-year randomized clinical trial (Idiopathic Intracranial Hypertension Weight Trial) enrolled...

Abstract Therapeutics to reduce intracranial pressure are an unmet need. Preclinical data have demonstrated a novel strategy lower using glucagon-like peptide-1 (GLP-1) receptor signalling. Here, we translate these findings into patients by conducting randomized, placebo-controlled, double-blind trial assess the effect of exenatide, GLP-1 agonist, on in idiopathic hypertension. Telemetric catheters enabled long-term monitoring. The enrolled adult women with active hypertension (intracranial...

Idiopathic Intracranial Hypertension (IIH) is characterized by an elevation of intracranial pressure (ICP no identifiable cause. The aetiology remains largely unknown, however observations made in a number recent clinical studies are increasing the understanding disease and now provide basis for evidence-based treatment strategies. Embase, CDSR, CENTRAL, DARE MEDLINE databases were searched up to 1st June 2018. We analyzed randomized controlled trials systematic reviews that investigate IIH....

Idiopathic intracranial hypertension (IIH) is a condition of unknown etiology, characterized by elevated pressure frequently manifesting with chronic headaches and visual loss. Similar to polycystic ovary syndrome (PCOS), IIH predominantly affects obese women reproductive age. In this study, we comprehensively examined the systemic cerebrospinal fluid (CSF) androgen metabolome in comparison sex-, BMI-, age-matched control groups either simple obesity or PCOS (i.e., excess). Women showed...
