Efficient charge transport has been observed in iodide-based room-temperature ionic liquids when doped with iodine. To investigate preferred pathways for the iodide (I(-))-to-triiodide (I3(-)) exchange reaction and to clarify the origin of this high ionic conductivity, we have conducted electronic structure calculations in the crystal state of 1-butyl-3-methylimidazolium iodide ([BMIM][I]). Energy barriers for the different stages of the iodine-swapping process, including the reorientation of the I(-)···I3(-) moiety, were determined from minimum energy paths as a function of a reaction coordinate...

The peroneus tertius muscle arises in the anterior compartment of the leg and demonstrates significant morphologic variation. Its function is not yet clearly delineated. We present the case of a 12-year-old patient with an isolated tear of the peroneus tertius tendon that resulted in lateral based ankle pain. After surgical reconstruction, the patient's pain resolved, and he was able to return to his normal activities.

INTRODUCTION: (68) Ga-PSMA positron emission tomography-computed tomography (PET/CT) is useful for both staging and assessment of biochemical relapse in men with prostate cancer. Renal excretion of (68) Ga-PSMA can lead to difficulties in scan interpretation, particularly in the pelvis. We evaluated if intravenous Frusemide at the time of (68) Ga-PSMA injection reduces excreted activity artefact and improves diagnostic certainty. METHODS: Sixty-two men with prostate cancer undergoing clinically indicated (68) Ga-PSMA PET/CT were prospectively included, 30 men receiving Frusemide at the time of radiotracer injection...

Objective: The dopamine hypothesis is one of the most influential theories of the neurobiological background of schizophrenia (SCZ). However, direct evidence for abnormal dopamine-related subcortical-cortical circuitry disconnectivity is still lacking. The aim of this study was therefore to test dopamine-related substantia nigra (SN)-based striato-thalamo-cortical resting-state functional connectivity (FC) in SCZ. Method: Based on our a priori hypothesis, we analyzed a large sample resting-state functional magnetic resonance imaging (fMRI) dataset from first-episode drug-naïve SCZ patients (n = 112) and healthy controls (n = 82) using the SN as the seed region for an investigation of striato-thalamo-cortical FC...

The Beaumont Behavioural Inventory (BBI) is a behavioural proxy report for the assessment of behavioural changes in ALS. This tool has been validated against the FrSBe, a non-ALS-specific behavioural assessment, and further comparison of the BBI against a disease-specific tool was considered. This study cross-validates the BBI against the ALS-FTD-Q. Sixty ALS patients, 8% also meeting criteria for FTD, were recruited. All patients were evaluated using the BBI and the ALS-FTD-Q, completed by a carer. Correlational analysis was performed to assess construct validity...

BACKGROUND: Neonatal central diabetes insipidus (NCDI) remains a therapeutic challenge, as extremely low doses of enteral desmopressin cannot be titrated with current preparations. The aim of this study was to describe the use of orally administered dilute desmopressin in NCDI. METHODS: Nasal desmopressin (100 μg/mL) was diluted in 0.9% saline to 10 μg/mL. Infants were treated with 1-5 μg and doses were titrated to a twice-daily regimen. The feed volume was 150 mL/kg/day and titrated according to weight gain...

PURPOSE: Port-A-Cath devices are frequently used for long-term venous access. We postulate that long-term use predisposes them to getting stuck and retained in a central vein at the time of removal. We aim to report the incidence and outcome of this complication. METHODS: Between January 2006 and July 2016, a retrospective review of all Port-A-Cath removals that were performed at our centre was conducted. At the time of removal, catheters that could not be removed from the vein were considered retained...

We report the direct chemoselective Brown-type oxidation of aryl organoboron systems containing two oxidizable boron groups. Basic biphasic reaction conditions enable selective formation and phase transfer of a boronic acid trihydroxyboronate in the presence of boronic acid pinacol (BPin) esters, while avoiding speciation equilibria. Spectroscopic investigations validate a base-promoted phase-selective discrimination of organoboron species. This phenomenon is general across a broad range of organoboron compounds and can also be used to invert conventional protecting group strategies, enabling chemoselective oxidation of BMIDA species over normally more reactive BPin substrates...

Frontotemporal dementia is associated with considerable clinical, genetic and pathological heterogeneity. The objective of this study is to characterise the imaging signatures of the main FTD phenotypes along the ALS-FTD spectrum. A total of 100 participants underwent comprehensive multimodal neuroimaging, genetic testing and neuropsychological evaluation. Seven patients with behavioural variant FTD (bvFTD), 11 patients with non-fluent-variant primary progressive aphasia (nfvPPA), two patients with sematic-variant primary progressive aphasia(svPPA), 10 patients with amyotrophic lateral sclerosis and FTD carrying the C9orf72 hexanucleotide repeat (C9 + ALS-FTD), 10 patients with ALS-FTD without hexanucleotide repeats (C9-ALS-FTD), 20 ALS patients without behavioural or cognitive deficits (ALSnci) and 40 healthy controls (HC) were included in a prospective quantitative neuroimaging study...

The protoplast retracts during apoptosis-like programmed cell death (AL-PCD) and, if this retraction is an active component of AL-PCD, it should be used as a defining feature for this type of programmed cell death. We used an array of pharmacological and genetic tools to test if the rates of protoplast retraction in cells undergoing AL-PCD can be modulated. Disturbing calcium flux signalling, ATP synthesis and mitochondrial permeability transition all inhibited protoplast retraction and often also the execution of the death programme...

A 2-year-old girl presented to the emergency department with a 3-day history of a painful stiff neck after getting a kick to her head from her older brother. Her general practitioner had recently started her on oral antibiotics for otitis media. Plain film imaging of her cervical spine on admission revealed anterior subluxation of C2 on C3 suggestive of bifacetal dislocation. Subsequent CT imaging confirmed malalignment of the upper cervical spine. The patient was admitted and worked up with MRI of the cervical spine which unexpectedly revealed a large 4×2 cm retropharyngeal abscess extending from C1 to C4...

Advanced biliary tract cancer (BTC) has a poor prognosis and limited treatment options. The PI3K/Akt/mTOR signaling pathway is hyperactivated in a subset of BTCs and clinical activity to the mTOR inhibitor everolimus has been observed in some BTC patients. The goal of this study was to identify biomarkers predictive of everolimus response. Twenty BTC cell lines were assessed for everolimus sensitivity with a spectrum of growth inhibitory responses observed. Molecular biomarkers of sensitivity and resistance were identified by interrogation of the activation status of the Ras/MAPK and PI3K/Akt/mTOR pathways...

Nuclear-receptors are often overexpressed in tumours and can thereby be used as targets when designing novel selective chemotherapeutic agents. To date, many conjugates incorporating an estrogen receptor (ER) ligand have been synthesised in order to direct chemical agents to tissue sites containing ERs. A series of ER ligand conjugates were synthesised incorporating an antagonistic ER ligand scaffold based on endoxifen, covalently-bound via an amide linkage to a variety of combretastatin-based analogues, which may act as antimitotic agents...

INTRODUCTION: Autonomous motivation (motivation to engage in a behavior because of personal choice, interest, or value) is often associated with health behaviors. The present study contributes to research on motivation and eating behaviors by examining (1) how autonomous motivation is correlated within parent-adolescent dyads and (2) whether parent- and adolescent-reported autonomous motivation predicts the parent-adolescent correlation in fruit and vegetable (FV) intake frequency. METHODS: Data were drawn from the Family Life, Activity, Sun, Health, and Eating (FLASHE) Study, a cross-sectional U...

A 76-year-old man presented to the emergency department complaining of acute urinary retention (AUR) and severe constipation. His recent medical history included 4 days of treatment in the community for gluteal herpes zoster with famciclovir. A transurethral catheter was passed and the patient completed a full course of famciclovir with resolution of constipation. The patient's catheter was successfully removed 3 weeks after his presentation. We report on the clinical presentation and management of an unusual case of AUR and constipation caused by a zoster viral infection of the S2-S4 dermatome...
