Confinement of reactive chemical species uniquely affects chemical reactivity by restricting the physical space available and by restricting access to interactions with the solvent. In Nature, for example, confined protein binding pockets govern processes following photoisomerization reactions and the isomerizations themselves. Here we describe the first example of a dihydroazulene/vinylheptafulvene (DHA/VHF) photo-switch functioning in water, and we show how its switching behavior is strongly influenced by supramolecular interactions with a series of cucurbit[n]uril (CB) host molecules...

Gram-negative isolates (n = 84) from 71% of free-ranging Eastern box turtles (Terrapene carolina carolina) in Illinois and Tennessee, United States, demonstrated resistance to at least one antibiotic while 30% of isolates demonstrated resistance to two or more antibiotics. Resistance was observed against cefoxitin, amoxicillin-clavulanic acid, cefazolin, ampicillin, ticarcillin, cefovecin, and ceftiofur. Gram-positive bacteria were isolated from 49 turtles, and all were observed to be resistant to two or more antibiotics...

Fibrinolytic dysregulation is an important mechanism in traumatic coagulopathy. It is an incompletely understood process that consists of a spectrum ranging from excessive breakdown (hyperfibrinolysis) and the shutdown of fibrinolysis. Both hyperfibrinolysis and shutdown are associated with excess mortality and post-traumatic organ failure. The pathophysiology appears to relate to endothelial injury and hypoperfusion, with several molecular markers identified in playing a role. Although there are no universally accepted diagnostic tests, viscoelastic studies appear to offer the greatest potential for timely identification of patients presenting with fibrinolytic dysregulation...

Martin Krøyer Rasmussen
Primary hepatocytes are widely used in the study of dynamic events like regulation of gene expression, as they are superior to most cell-lines. However, the culturing of the hepatocytes often results in loss of phenotype, e.g. the expression of the cytochrome p450s (CYP). The present study investigated the impact of serum in the culture medium of porcine primary hepatocytes (PPH) on markers of dedifferentiation as well as the impact on CYP induction. The effects were studied in both freshly isolated primary hepatocytes as well as cryopreserved...

BACKGROUND: While there are guidelines for the use of intravenous immunoglobulins in children with Guillain-Barre syndrome and myasthenia gravis based on high-level evidence studies, data is fewer for the majority of neurologic disorders in this age group. Neuronal antibodies are detected in children with seizures of autoimmune etiology. Intravenous immunoglobulins with their broad immunomodulatory mechanism of action could be ideally effective in different forms of immune-dysregulated intractable epilepsies such as autoimmune epilepsy and autoimmune Rasmussen encephalitis...

BACKGROUND AND PURPOSE: Phosphodiesterase 1 (PDE1), a subfamily of cyclic nucleotide phosphodiesterases consisting of three isoforms, PDE1A, PDE1B, and PDE1C, has been implicated in regulation of vascular tone. The PDE1 isoform(s) responsible for tone regulation is unknown. This study used isoform-preferring PDE1 inhibitors, Lu AF58027, Lu AF64196, Lu AF66896, and Lu AF67897, to investigate the relative contribution of PDE1 isoforms to regulation of vascular tone. EXPERIMENTAL APPROACH: In rat mesenteric arteries, expression and localisation of Pde1 isoforms were determined by qPCR and in situ hybridisation, and physiological impact of PDE1 inhibition were evaluated by isometric tension recordings...

Secukinumab (anti-IL17A) is effective as treatment for moderate to severe plaque psoriasis, but real-life data on effectiveness and safety lack. We aimed to present real-life data of all Danish patients treated with secukinumab (n = 69). At baseline, before initiation of treatment with secukinumab 300 mg (47.8%) or off-label treatment with secukinumab 150 mg (52.2%), the median PASI score was 7.1. A total of 66.7% (34/51) and 52.9% (27/51) of patients still on secukinumab at week 12 achieved a PASI (Psoriasis Area and Severity Index)-50 and PASI-75 of 66...

Anti-neutrophil cytoplasmic antibodies (ANCAs) are valuable laboratory markers used for the diagnosis of well-defined types of small-vessel vasculitis, including granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA). According to the 1999 international consensus on ANCA testing, indirect immunofluorescence (IIF) should be used to screen for ANCAs, and samples containing ANCAs should then be tested by immunoassays for proteinase 3 (PR3)-ANCAs and myeloperoxidase (MPO)-ANCAs. The distinction between PR3-ANCAs and MPO-ANCAs has important clinical and pathogenic implications...

BACKGROUND: Patients experiencing disuse atrophy report acute loss of skeletal muscle mass which subsequently leads to loss of strength and physical capacity. In such patients, especially the elderly, complete recovery remains a challenge even with improved nutrition and resistance exercise. This study aimed to explore the clinical potential of bimagrumab, a human monoclonal antibody targeting the activin type II receptor, for the recovery of skeletal muscle volume from disuse atrophy using an experimental model of lower extremity immobilization...

PURPOSE: Historically, the process of positioning a patient prior to imaging verification used a set of permanent patient marks, or tattoos, placed subcutaneously. After aligning to these tattoos, plan specific shifts are applied and the position is verified with imaging, such as cone-beam computed tomography (CBCT). Due to a variety of factors, these marks may deviate from the desired position or it may be hard to align the patient to these marks. Surface-based imaging systems are an alternative method of verifying initial positioning with the entire skin surface instead of tattoos...

Contrasting Greenland and Antarctic temperatures during the last glacial period (115,000 to 11,650 years ago) are thought to have been driven by imbalances in the rates of formation of North Atlantic and Antarctic Deep Water (the 'bipolar seesaw'). Here we exploit a bidecadally resolved (14)C data set obtained from New Zealand kauri (Agathis australis) to undertake high-precision alignment of key climate data sets spanning iceberg-rafted debris event Heinrich 3 and Greenland Interstadial (GI) 5.1 in the North Atlantic (~30,400 to 28,400 years ago)...

BACKGROUND: Glycated hemoglobin (HbA1c) is used to diagnose type 2 diabetes (T2D) and assess glycemic control in patients with diabetes. Previous genome-wide association studies (GWAS) have identified 18 HbA1c-associated genetic variants. These variants proved to be classifiable by their likely biological action as erythrocytic (also associated with erythrocyte traits) or glycemic (associated with other glucose-related traits). In this study, we tested the hypotheses that, in a very large scale GWAS, we would identify more genetic variants associated with HbA1c and that HbA1c variants implicated in erythrocytic biology would affect the diagnostic accuracy of HbA1c...

Markers of target-organ damage and 24-hour ambulatory blood pressure (BP) measurement improve cardiovascular risk stratification. The prevalence of target-organ damage and raised BP increases with aging. The study aim was to evaluate the impact of age and target-organ damage on the prognostic value of ambulatory BP. Markers of target-organ damage and ambulatory BP were measured in 1408 healthy people aged 41 or 51 (middle-aged group), and 61 or 71 (older group) years. The primary outcome was cardiovascular events after 16 years of follow-up, with data obtained from national registries...
