Reactive oxygen and nitrogen species (RONS) may infringe on the passing of pristine genetic information by inducing DNA inter- and intra-strand crosslinks, protein-DNA crosslinks, and chemical alterations to the sugar or base moieties of DNA. 8-Oxo-7,8-dihydroguanine (8-oxoG) is one of the most prevalent DNA lesions formed by RONS and is repaired through the base excision repair (BER) pathway involving the DNA repair glycosylases OGG1 and MUTYH in eukaryotes. MUTYH removes adenine (A) from 8-oxoG:A mispairs, thus mitigating the potential of G:C to T:A transversion mutations from occurring in the genome...

OBJECTIVE: Our objective was to safely reduce the number of peripherally inserted central catheters (PICCs) inserted in infants with umbilical venous catheter using quality improvement methods. STUDY DESIGN: In a tertiary neonatal intensive care unit, a questionnaire designed to prompt critical thinking around the decision to place a PICC, along with an updated standardized feeding guideline was introduced. PICC insertion in 86 infants with umbilical venous catheter (pre intervention) with birth weight 1000-1500 g were compared with 115 infants (post intervention) using Fisher's exact test...

We mark the 50th anniversary of the International Committee on Taxonomy of Viruses (ICTV) by presenting a brief history of the organization since its foundation, showing how it has adapted to advancements in our knowledge of virus diversity and the methods used to characterize it. We also outline recent developments, supported by a grant from the Wellcome Trust (UK), that are facilitating substantial changes in the operations of the ICTV and promoting dialogue with the virology community. These developments will generate improved online resources, including a freely available and regularly updated ICTV Virus Taxonomy Report...

OBJECTIVE: To demonstrate that progress has been made in unifying brain death determination guidelines in the last decade by directly comparing the policies of the US News and World Report's top 50 ranked neurologic institutions from 2006 and 2015. METHODS: We solicited official hospital guidelines in 2015 from these top 50 institutions, generated summary statistics of their criteria as benchmarked against the American Academy of Neurology Practice Parameters (AANPP) and the comparison 2006 cohort in 5 key categories, and statistically compared the 2 cohorts' compliance with the AANPP...

This paper is based upon the "8th Charles Lieber's Satellite Symposium" organized by Manuela G. Neuman at the Research Society on Alcoholism Annual Meeting, onJune 25, 2016 at New Orleans, Louisiana, USA. The integrative symposium investigated different aspects of alcohol-induced liver disease (ALD) as well as non-alcohol-induced liver disease (NAFLD) and possible repair. We revealedthe basic aspects of alcohol metabolism that may be responsible for the development of liver diseaseas well as the factors that determine the amount, frequency and which type of alcohol misuse leads to liver and gastrointestinal diseases...

REVIEW
Angela J Marolf
Recent advances in diagnostic imaging of the hepatobiliary system include MRI, computed tomography (CT), contrast-enhanced ultrasound, and ultrasound elastography. With the advent of multislice CT scanners, sedated examinations in veterinary patients are feasible, increasing the utility of this imaging modality. CT and MRI provide additional information for dogs and cats with hepatobiliary diseases due to lack of superimposition of structures, operator dependence, and through intravenous contrast administration...

Because of their biocompatibility, biodegradability, and unique bioactive properties, polysaccharides have been recognized and directly applied as excellent candidates for various biomedical applications. In order to introduce more functionalities onto polysaccharides, various modification methods were applied to improve the physical-chemical and biochemical properties. Grafting polysaccharides with functional polymers with limited reaction sites maximizes the structural integrity. To the best of our knowledge, great efforts have been made by scientists across the world, including our research group, to explore different strategies for the synthesis and design of controllable polymer-grafted polysaccharides...

The pursuit of small molecule mGlu5 NAMs as treatments for a variety of psychiatric and neurodegenerative disorders has developed into a mature field. In addition to extensive preclinical studies, multiple compounds have advanced into clinical trials with the most advanced studies occurring in patients with FXS, PD-LID, and MDD. Areas covered: This review begins with an update of the clinical activity with mGlu5 NAMs, and then moves into a summary of patent applications filed since 2013. The summaries are organized into three separate sections: (1) inventions centered on improvements to existing clinical compounds; (2) new small molecules that maintain the prototypical disubstituted alkyne chemotype found in many mGlu5 NAM compounds; and (3) new small molecules that are not from a disubstituted alkyne chemotype...

AIMS: Adult congenital heart disease (ACHD) predisposes to infective endocarditis (IE). Surgical advancements have changed the ACHD population, whereas associated prosthetic material may constitute additional IE targets. We aimed to prospectively determine contemporary incidence, risk factors, and predictors of IE in a nationwide ACHD cohort, focusing on the presence of prosthetics. METHODS AND RESULTS: We identified 14 224 patients prospectively followed in the CONCOR ACHD registry (50...

BACKGROUND: The Lithiumeter was developed as a visual and practical guide for determining lithium levels in the management of bipolar disorder (BD). It appears to have been well received, as evidenced by its increasing popularity amongst doctors as a deskside clinical aide, and adoption and reproduction of the schematic in clinical guidelines and texts. However, since its publication 5 years ago, key basic neuroscience and clinical research developments pertaining to lithium have significantly advanced our understanding, necessitating further refinement of guidance concerning the practicalities of lithium therapy...

For centuries, honey has been utilized for wound healing purposes. In recent times, this specific topic has become a field of interest, possibly due to the advent of antibiotic resistance in microbial pathogens. With constant technological advancement, the information regarding honey's mechanisms of action on wound healing has accumulated at a rapid pace. Similarly, clinical studies comparing honey with traditional wound care therapies are steadily emerging. As a follow-up to a previous review published in the journal in 2011, the current review article outlines publications regarding honey and wound healing that have been published between June 2010 and August 2016...

The anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) are a group of disorders characterized by necrotizing inflammation of the small to medium vessels in association with autoantibodies against the cytoplasmic region of the neutrophil. Included in this definition are granulomatosis with polyangiitis (GPA, formerly known as Wegener's granulomatosis), microscopic polyangiitis (MPA) and eosinophilic granulomatosis with polyangiitis (formerly known as Churg-Strauss syndrome). AAV are chronic, often relapsing diseases that can be organ or life threatening...

REVIEW
Farman Ullah Dawar, Junjie Wu, Lijuan Zhao, Muhammad Nasir Khan Khattak, Jie Mei, Li Lin
Cyclophilin A (CypA), a well-recognized receptor for anti-inflammatory drug cyclosporine A (CsA) is a ubiquitous and multifunctional protein. Beside the diverse intracellular functions, CypA is secreted against inflammatory stimuli, where it activates and attracts leukocytes via CD147 to the stimulus site. Interestingly, it synergizes with other factors to induce leukocyte migration in different animals. However, the silencing and inhibition of CypA or CD147 inhibits leukocytes chemotaxis and inflammation. This review focuses on the advances made in understanding the mechanism of CypA-dependent leukocytes chemotaxis and hence, recognition of this factor as a possible therapeutic target in inflammatory diseases...

PURPOSE: Dual-energy CT (DECT) enhances tissue characterization because of its basis material decomposition capability. In addition to conventional two-material decomposition from DECT measurements, multi-material decomposition (MMD) is required in many clinical applications. To solve the ill-posed problem of reconstructing multiple-material images from dual-energy measurements, additional constraints are incorporated into the formulation, including volume and mass conservation and the assumptions that at most three materials in each pixel and various material types among pixels...
