Cobalt oxyhydroxide (CoOOH) nanosheets are efficient fluorescence quenchers due to their specific optical properties and high surface area. The combination of CoOOH nanosheets and carbon dots (CDs) has not been used in any aptasensor based on fluorescence quenching so far. An aptamer based fluorometric assay is introduced that is making use of fluorescent CDs conjugated to the aptamer against methamphetamine (MTA), and of CoOOH nanosheets which reduce the fluorescence of the CDs as a quencher. The results revealed that the conjugated CDs with aptamers were able to enclose the CoOOH nanosheets...

RATIONALE: Tumor necrosis factor (TNF-α) participates in the pathophysiology of Behcet's disease (BD) and myelodysplastic syndrome (MDS). Infliximab is recommaned for the most severe type of BD, however, there is little evidence for its effectiveness in BD associated MDS. PATIENT CONCERNS: A 46-year-old female, initially diagnosed with intestinal BD and leukopenia was later diagnosed as MDS. Treatement with infliximab and other immunoregulators lead to life-threatening pneumonia...

Wilms' tumor 1 (WT1) is constantly expressed in leukemic cells of acute leukemia and myelodysplastic syndrome (MDS). A T-cell receptor (TCR) that specifically reacts with WT1 peptide in the context of HLA-A*24:02 has been identified. We conducted a first-in-human trial of TCR-gene transduced T-cell (TCR-T-cell) transfer in patients with refractory acute myeloblastic leukemia (AML) and high-risk MDS to investigate the safety and cell kinetics of the T cells. The WT1-specific TCR-gene was transduced to T cells using a retroviral vector encoding small interfering RNAs for endogenous TCR genes...

PURPOSE: Most adolescent and young adult (AYA)-aged childhood cancer survivors develop physical and/or psychosocial sequelae; however, many do not receive long-term follow-up (LTF) critical for screening, prevention, and treatment of late effects. To develop a health services research agenda to optimize care models, we conducted qualitative research with LTF providers examining existing models, and successes and challenges in maintaining survivors' connections to care across their transition to adulthood...

The mutation of short tandem repeat (STR) loci is affected by several factors, such as sex, age, and DNA architectures. Previous studies have shown a different profile of mutation rates at autosomal STR loci among populations. It is important to provide population data and reveal underlying factors influencing the evaluation of STR mutation rates. In this study, we performed a comprehensive analysis on the mutation of 19 autosomal STR loci through 124,773 parent-child allelic transfers from 5846 paternity testing cases...

Perturbations in CREB binding protein (CREBBP) are associated with hematopoietic malignancies, including myelodysplastic syndrome (MDS). Mice hemizygous for Crebbp develop myelodysplasia with proliferative features, reminiscent of human MDS/myeloproliferative neoplasm-unclassifiable (MDS/MPN-U), and a proportion goes on to develop acute myeloid leukemia (AML). We have also shown that the Crebbp+/- non-hematopoietic bone marrow microenvironment induces excessive myeloproliferation of wild-type cells. We now report that transplantation of unfractionated Crebbp+/- bone marrow into wild-type recipients resulted in either early-onset AML or late-onset MDS and MDS/MPN-U...

Mauricio A Escobar, Carolynn J Morris
BACKGROUND: The American College of Surgeons Committee on Trauma (ACS-COT) view over- and undertriage rates based on trauma team activation (TTA) criteria as surrogate markers for quality trauma patient care. Undertriage occurs when classifying patients as not needing a TTA when they do. Over-triage occurs when a TTA is unnecessarily activated. ACS-COT recommends undertriage <5% and overtriage 25-35%. We sought to improve the under-triage and over-triage rates at our Level II Pediatric Trauma Center by updating our outdated trauma team activation criteria in an evidence-based fashion to better identify severely injured children and improving adherance to following established trauma team activation criteria...

The widespread use of silver nanoparticles (AgNPs) would likely result in their discharge into wastewater and inevitable release in densely populated coastal areas. It is known that AgNPs can cause harmful effects to marine fauna, but how they affect development stages is still an open question. In order to understand in details how polymer-coated AgNPs (PAAm-AgNPs) (from 0.19 to 4.64mM as Ag) can affect critical stages of marine invertebrate development, metamorphic larvae and juveniles of sea urchins were used as biological models...

Solvent plays a key role in diverse physico-chemical and biological processes. Therefore, understanding solute-solvent interactions at the molecular level of detail is of utmost importance. A comprehensive solvatochromic analysis of benzophenone (Bzp) was carried out in various solvents using Raman and electronic spectroscopy, in conjunction with Density Functional Theory (DFT) calculations of supramolecular solute-solvent clusters generated using classical Molecular Dynamics Simulations (c-MDSs). The >C=O stretching frequency undergoes a bathochromic shift with solvent polarity...

Exosomes/microvesicles (MVs) provide a mechanism of intercellular communication. Our hypothesis was that mesenchymal stromal cells (MSC) from myelodysplastic syndrome (MDS) patients could modify CD34+ cells properties by MVs. They were isolated from MSC from MDS patients and healthy donors (HD). MVs from 30 low-risk MDS patients and 27 HD were purified by ExoQuick-TC™ or ultracentrifugation and identified by transmission electron microscopy, flow cytometry (FC) and western blot for CD63. Incorporation of MVs into CD34+ cells was analyzed by FC, and confocal and fluorescence microscopy...

INTRODUCTION: Education, being a process of knowledge transfer always has advances which are generally on par with the discovery of newer technologies. Currently, most of the education process has shifted away from the conventional black board towards the usage of more student friendly technologies. This leads us to the aim of this study, which is to analyse the impact of video based learning on the performance of dental post graduate students in their biostatistics course. MATERIALS AND METHODS: A new video based discussion method was followed to teach biostatistics to MDS postgraduate students in 2013 (test group, n=44)...
