Facilitated Intravascular Ultrasound-Guided Balloon-Assisted Re-Entry Technique for Complex Lower-Extremity Chronic Total Occlusions: The FIBRE Technique.

Purpose: To examine the efficacy and safety of the facilitated intravascular ultrasound (IVUS)-guided balloon assisted-re-entry (FIBRE) technique in the treatment of complex, chronic total occlusion (CTO) peripheral arterial lesions.

Methods: A retrospective analysis of 150 patients undergoing peripheral intervention for lower extremity CTO was performed from 2014 to 2017 at two institutions. From the selected population, 10 patients with complex CTOs were identified using the FIBRE technique.

Hypochloraemia and 30 day readmission rate in patients with acute decompensated heart failure.

Aims: Despite recent advances in guideline-directed therapy, rehospitalization rates for acute decompensated heart failure (ADHF) remain high. Recently published studies demonstrated the emerging role of hypochloraemia as a predictor of poor outcomes in patients with ADHF. This study sought to determine the correlation between low serum chloride and 30 day hospital readmission in patients with ADHF.

The utility of S100B level in detecting mild traumatic brain injury in intoxicated patients.

Background: S100B is a serum protein known to elevate in patients with brain injury, but it is unknown whether it can predict intracranial pathology in intoxicated patients following mild traumatic brain injury (MTBI). We performed a systematic review and meta-analysis of the English language literature to address this question.

Main Outcomes And Results: Four prospective cohort trials of serum S100B levels on acutely intoxicated patients with MTBI were included in this meta-analysis.

AGEP overlap induced by hydroxychloroquine: a case report and literature review.

Acute Generalized Exanthematous Pustulosis (AGEP) is a rare drug reaction manifesting as pustular lesions with surrounding erythema following exposure. The disease is often self-limited and treatment is supportive. It may present in an atypical variant with vesicles that desquamate into erosions, which classifies the disease as an AGEP/SJS Overlap.

Closed-Eye Visualizations in the Setting of Hyponatremia.

Purpose: To report a case of closed-eye visualizations and to clarify the different types of hallucinations and their etiologies.

Methods: Retrospective case report of a patient with closed-eye visualizations secondary to hyponatremia. Clinical findings, physical exam, laboratory assessment, treatment, and disease course from the patient's hospitalization were used in creating this report.

Effects of prophylactic anticholinergic medications to decrease extrapyramidal side effects in patients taking acute antiemetic drugs: a systematic review and meta-analysis.

Objectives: To determine the effectiveness of prophylactic anticholinergic medications in reducing extrapyramidal symptoms in patients taking acute antiemetics with a dopamine D2 receptor antagonist effect.

Methods: Systematic searches of all published studies through March 2017 were identified from PubMed, Cochrane library, Embase, Web of Science and Scopus. Only randomised controlled trials of patients receiving dopamine D2 antagonist antiemetic therapy for acute migraine in which an anticholinergic or placebo was compared were included.

A ferritin-based label for cellular electron cryotomography.

Electron cryotomography provides nanometer resolution structural detail of thin biological specimens in a near-native state. Currently, its application is limited by the lack of a specific label for the identification of molecules. Our aim was to develop such a label, analogous to GFP used in fluorescence microscopy.

Structural analysis of the ParR/parC plasmid partition complex.

Accurate DNA partition at cell division is vital to all living organisms. In bacteria, this process can involve partition loci, which are found on both chromosomes and plasmids. The initial step in Escherichia coli plasmid R1 partition involves the formation of a partition complex between the DNA-binding protein ParR and its cognate centromere site parC on the DNA.

Concatenated metallothionein as a clonable gold label for electron microscopy.

Localization of proteins in cells or complexes using electron microscopy has mainly relied upon the use of heavy metal clusters, which can be difficult to direct to sites of interest. For this reason, we would like to develop a clonable tag analogous to the clonable fluorescent tags common to light microscopy. Instead of fluorescing, such a tag would initiate formation of a heavy metal cluster.

Double-stranded DNA translocation: structure and mechanism of hexameric FtsK.

FtsK is a DNA translocase that coordinates chromosome segregation and cell division in bacteria. In addition to its role as activator of XerCD site-specific recombination, FtsK can translocate double-stranded DNA (dsDNA) rapidly and directionally and reverse direction. We present crystal structures of the FtsK motor domain monomer, showing that it has a RecA-like core, the FtsK hexamer, and also showing that it is a ring with a large central annulus and a dodecamer consisting of two hexamers, head to head.

Gold nanocluster formation using metallothionein: mass spectrometry and electron microscopy.

Clonable contrasting agents for light microscopy, such as green fluorescent protein, have revolutionized biology, but few such agents have been developed for transmission electron microscopy (TEM). As an attempt to develop a novel clonable contrasting agent for TEM, we have evaluated metallothionein, a small metal-binding protein, reacted with aurothiomalate, an anti-arthritic gold compound. Electro spray ionization and matrix-assisted laser desorption/ionization (MALDI) mass spectrometry measurements show a distribution of gold atoms bound to individual metallothionein molecules.
