Long-term testosterone replacement therapy is mainly monitored by trough levels of serum testosterone (S-T), while urinary testosterone (U-T) is used by forensic toxicology to evaluate testosterone doping. Testosterone in saliva (Sal-T) may provide additional information and simplify the sample collection. We aimed to investigate the relationships between testosterone measured in saliva, serum and urine during standard treatment with 1,000 mg testosterone undecanoate (TU) every 12th week during 1 year. This was an observational study...

Residual viremia is common during antiretroviral therapy (ART), and could be caused by ongoing low-level virus replication or by release of viral particles from infected cells. ART Intensification should impact ongoing viral propagation but not virion release. Eighteen acutely infected men were enrolled in a randomized controlled trial, and followed for a median of 107 weeks. Participants started ART with (n=9) or without (n=9) intensification with maraviroc (MVC) within 90 days of infection. Levels of HIV DNA and cell-free RNA were quantified by droplet digital PCR...

OBJECTIVE: To assess the diagnostic performance of three high-sensitive assays in a cohort of TgAb-negative and TgAb-positive differentiated thyroid cancer (DTC) patients. DESIGN: Retrospective study on prospectively selected DTC patients. METHODS: Serum samples from 154 DTC patients were obtained 6-12 months after radioiodine ablation and tested by Beckman, Roche, BRAHMS Tg and TgAb assays, respectively. Receiver operating characteristics curves for Tg were plotted using outcome over time as benchmark and assay-specific Tg thresholds were obtained for TgAb-negative and TgAb-positive patients...

BACKGROUND: Bevacizumab is approved for the treatment of patients with progressive glioblastoma on the basis of uncontrolled data. Data from a phase 2 trial suggested that the addition of bevacizumab to lomustine might improve overall survival as compared with monotherapies. We sought to determine whether the combination would result in longer overall survival than lomustine alone among patients at first progression of glioblastoma. METHODS: We randomly assigned patients with progression after chemoradiation in a 2:1 ratio to receive lomustine plus bevacizumab (combination group, 288 patients) or lomustine alone (monotherapy group, 149 patients)...

BACKGROUND: Local anaesthetics (LA) reduce neuronal excitability by inhibiting voltage-gated Na+ channels. When applied at high concentrations in the direct vicinity of nerves, LAs can also induce relevant irritation and neurotoxicity via mechanisms involving an increase of intracellular Ca2+. In the present study we explored the role of the Ca2+-permeable ion channels TRPA1 and TRPV1 for lidocaine-induced Ca2+-influx, neuropeptide release and neurotoxicity in mouse sensory neurons. METHODS: Cultured dorsal root ganglion (DRG) neurons from wildtype and mutant mice lacking TRPV1, TRPA1 or both channels were explored by means of calcium imaging, whole-cell patch clamp recordings and trypan blue staining for cell death...

FFQ, food diaries and 24 h recall methods represent the most commonly used dietary assessment tools in human studies on nutrition and health, but food intake biomarkers are assumed to provide a more objective reflection of intake. Unfortunately, very few of these biomarkers are sufficiently validated. This review provides an overview of food intake biomarker research and highlights present research efforts of the Joint Programming Initiative 'A Healthy Diet for a Healthy Life' (JPI-HDHL) Food Biomarkers Alliance (FoodBAll)...

Elastocapillarity describes the deformations of soft materials by surface tensions and is involved in a broad range of applications, from microelectromechanical devices to cell patterning on soft surfaces. Although the vast majority of elastocapillarity experiments are performed on soft gels, because of their tunable mechanical properties, the theoretical interpretation of these data has been so far undertaken solely within the framework of linear elasticity, neglecting the porous nature of gels. We investigate in this work the deformation of a thick poroelastic layer with surface tension subjected to an arbitrary distribution of time-dependent axisymmetric surface forces...

Compelling data in the literature from the recent years leave no doubt about the pluridimensional nature of G protein-coupled receptor function and the fact that some ligands can couple with different efficacies to the multiple pathways that a receptor can signal through, a phenomenon most commonly known as functional selectivity or biased agonism. Nowadays, transduction coefficients (log(τ/KA)), based on the Black and Leff operational model of agonism, are widely used to calculate bias. Nevertheless, combining both affinity and efficacy in a single parameter can result in compounds showing a defined calculated bias of one pathway over other though displaying varying experimental bias preferences...

BACKGROUND: Chronic rhinosinusitis (CRS) is a prevalent and disabling condition of the nose and sinuses. The natural history of CRS symptoms in a general population sample has not been previously studied. OBJECTIVE: In a general population-based sample from Pennsylvania, we used 2 questionnaires mailed 6 months apart to estimate the prevalence of, and identify predictors for, stability or change in symptoms over time. METHODS: We mailed the baseline and 6-month follow-up questionnaires to 23,700 primary care patients and 7,801 baseline responders, respectively...

This paper introduces the relational triangulation framework as a functional contextual expansion of the established Relational Frame Theory (Hayes, Barnes-Holmes, & Roche, 2001) account of perspective-taking. Initial support for the new framework is provided through data collected with a novel relational triangulation perspective-taking protocol configured in the present study to show contextual influence over deriving true belief in others following the direct training of a "seeing leads to knowing" repertoire (Leslie & Frith, 1988)...

BACKGROUND: Acute metabolic acidosis is rarely associated with a reduced or negative anion gap (AG), but several case reports have described such an abnormality occurring in the setting of acute salicylate intoxication. The underlying cause of this phenomenon is unclear. METHODS: In this retrospective cohort study, we reviewed our institutional database to identify all patients admitted for salicylate intoxication at Mayo Clinic (Rochester, MN, USA) from January 2010 through December 2012...

BACKGROUND: Whether the route of early feeding affects outcomes of patients with severe critical illnesses is controversial. We hypothesised that outcomes were better with early first-line enteral nutrition than with early first-line parenteral nutrition. METHODS: In this randomised, controlled, multicentre, open-label, parallel-group study (NUTRIREA-2 trial) done at 44 French intensive-care units (ICUs), adults (18 years or older) receiving invasive mechanical ventilation and vasopressor support for shock were randomly assigned (1:1) to either parenteral nutrition or enteral nutrition, both targeting normocaloric goals (20-25 kcal/kg per day), within 24 h after intubation...

Compound exocytosis is considered the most massive mode of exocytosis, during which the membranes of secretory granules (SGs) fuse with each other to form a channel through which the entire contents of their granules is released. The underlying mechanisms of compound exocytosis remain largely unresolved. Here we show that the small GTPase Rab5, a known regulator of endocytosis, is pivotal for compound exocytosis in mast cells. Silencing of Rab5 shifts receptor-triggered secretion from a compound to a full exocytosis mode, in which SGs individually fuse with the plasma membrane...

This study aimed to identify and qualify grasp-types used by patients with stroke and determine the clinical parameters that could explain the use of each grasp. Thirty-eight patients with chronic stroke-related hemiparesis and a range of motor and functional capacities (17 females and 21 males, aged 25-78), and 10 healthy subjects were included. Four objects were used (tissue packet, teaspoon, bottle and tennis ball). Participants were instructed to "grasp the object as if you are going to use it". Three trials were video-recorded for each object...
