Alterations in platelet secretion differentially affect thrombosis and hemostasis.
Abstract We genetically manipulated the major platelet vesicle-associated membrane proteins (VAMP2, VAMP3, and VAMP8) to create mice with varying degrees of disrupted platelet secretion. As previously shown, loss of VAMP8 reduced granule secretion, and this defect was exacerbated by further deletion of VAMP2 and VAMP3. VAMP2Δ3Δ8-/- platelets also had reduced VAMP7. Loss of VAMP2 and VAMP3 (VAMP2Δ3Δ) had a minimal impact on secretion when VAMP7 and VAMP8 were present. Integrin αIIbβ3 activation and aggregation were not affected, although spreading was reduced in VAMP2Δ3&Delt...

Immune checkpoint inhibitors as a bridge to allogeneic transplantation with posttransplant cyclophosphamide.
Abstract Published reports suggest that immune checkpoint inhibitors (ICIs) before allogeneic blood or marrow transplantation (alloBMT) may increase the incidence of graft-versus-host disease (GvHD), immune-related adverse events, and nonrelapse mortality (NRM); this led to the US Food and Drug Administration issuing a "Warning and Precaution" regarding the potential for life-threatening immune-mediated complications associated with alloBMT after nivolumab and pembrolizumab. We retrospectively reviewed the outcomes of 14 consecutive patients who received ICIs as their final salvage therapy before T-cell-...

Systematic Identification of Non-coding RNAs.
Abstract Non-coding RNAs (ncRNAs) are biologically significant in variable ways. They modulate gene expression at the levels of transcription and post-transcription. MiRNAs and lncRNAs are two major classes of non-coding RNAs and have been extensively characterized. They are implicated in various biological processes and diseases. Thus, identification of miRNAs and lncRNAs are fundamental to further understand their roles and dissect their mechanisms. Here, we overviewed pipelines of identifying miRNAs and lncRNAs based on next-generation sequencing technologies. We applied the pipelines to identify miRNAs in mult...

Profiling DNA Methylation Patterns of Non-coding RNAs (ncRNAs) in Human Disease.
Abstract Although non-coding RNAs (ncRNAs) are commonly considered modulators in human disease, revealing the methylation pattern of ncRNA is still a challenging task. In this chapter, we (1) introduced a strategy of constructing DNA methylation profiles for ncRNAs by reannotating data of DNA methylation arrays; (2) identified methylation patterns of ncRNAs in cancers by classifying ncRNAs into two categories and three subcategories, according to their promoter methylation patterns in tumors; (3) identified lncRNAs with promoter methylation patterns that were associated with cancer status, subtype, or prognosis fo...

Computationally Modeling ncRNA-ncRNA Crosstalk.
Abstract Our understanding of complex gene regulatory networks have been improved by the discovery of ncRNA-ncRNA crosstalk in normal and disease-specific physiological conditions. Previous studies have proposed numerous approaches for constructing ncRNA-ncRNA networks via ncRNA-mRNA regulation, functional information, or phenomics alone, or by combining heterogeneous data. Furthermore, it has been shown that ncRNA-ncRNA crosstalk can be rewired in different tissues or specific diseases. Therefore, it is necessary to integrate transcriptome data to construct context-specific ncRNA-ncRNA networks. In this chapter, ...

Investigation of Confounding Factors in Measuring Tissue Saturation with NIRS Spatially Resolved Spectroscopy.
Abstract Performing absolute measurements of tissue saturation of the brain with near-infrared spectroscopy (NIRS) is a clinically desirable brain monitoring tool. Tissue oxygenation index (TOI) is an indicator of absolute tissue mixed arterial and venous oxygen saturation, and can be calculated using a NIRS technique called spatially resolved spectroscopy (SRS). SRS instruments measure the change of light attenuation with distance by using multiple light source-detector distances at two or more wavelengths. The aim of the study is to use broadband NIRS SRS data to investigate the effects on the calculation of TOI...

A New Method Based on Virtual Fluence Detectors and Software Toolbox for Handheld Spectral Optoacoustic Tomography.
jos S Abstract A minimal setup for optoacoustic (OA) imaging requires an ultrasound probe and a pulsed laser. Such a system is capable of imaging small blood vessels and is sensitive to variations in their oxygen saturation. However, absolute oxygenation values cannot be obtained without a proper correction for the varying light fluence resulting from the optical attenuation in the surrounding tissue. Other techniques, such as near-infrared optical tomography (NIROT) can be employed to assist OA imaging for fluence compensation. In this paper, we propose using blood vessels as virtual fluence detectors (VD), which...

NGSPanPipe: A Pipeline for Pan-genome Identification in Microbial Strains from Experimental Reads.
Abstract Recent advancements in sequencing technologies have decreased both time span and cost for sequencing the whole bacterial genome. High-throughput Next-Generation Sequencing (NGS) technology has led to the generation of enormous data concerning microbial populations publically available across various repositories. As a consequence, it has become possible to study and compare the genomes of different bacterial strains within a species or genus in terms of evolution, ecology and diversity. Studying the pan-genome provides insights into deciphering microevolution, global composition and diversity in virulence...

Characterization and Antimicrobial Property of Some Heavy Metals Containing Ayurvedic Drugs.
Abstract Ayurvedic medicines are often used in different formulations, the heavy metals, which are generally referred to as being toxic. In this work, we report on the physicochemical characterization and biological activity of some typical Ayurvedic drugs available in the market that contain arsenic, mercury and lead with the emphasis on their antibacterial performance. Among the formulations studied, some of the drugs with 'amorphous' texture (and higher solubility) were found quite active against some bacterial strains whereas the formulations possessing crystalline texture (and low solubility) were found pract...

Health Perception and Adherence with Blood Pressure Control among Rural Chinese Adults with Hypertension.
CONCLUSION: These findings suggest: (a) healthcare providers should focus on educating rural hypertensive adults about healthful diets and behaviors to manage hypertension, especially for those with high household income; (b) knowledge-based health education alone is not adequate; (c) illness perception may not be directly associated with blood pressure and; (d) the Chinese Illness-Perception Questionnaire-Revised and the Inventory of Adherence to Self-management require validation and potential revision for use with rural Chinese populations.

The characteristics of vessel lining cells in normal spleens and their role in the pathobiology of myelofibrosis.
Abstract The CD34-CD8α+, sinusoid lining, littoral cells (LCs), and CD34+CD8α-, splenic vascular endothelial cells (SVECs) represent 2 distinct cellular types that line the vessels within normal spleens and those of patients with myelofibrosis (MF). To further understand the respective roles of LCs and SVECs, each was purified from normal and MF spleens, cultured, and characterized. Gene expression profiling indicated that LCs were a specialized type of SVEC. LCs possessed a distinct gene expression profile associated with cytoskeleton regulation, cellular interactions, endocytosis, and iron transport....

Epidemiology of AL amyloidosis: a real-world study using US claims data.
This study aimed to provide an up-to-date estimate of prevalence and incidence of AL amyloidosis in the United States. Using claims databases from years 2007 to 2015, adults ≥18 years old with AL amyloidosis were included if they had (1) at least 1 inpatient or 2 outpatient claims consistent with AL amyloidosis and (2) received 1 AL-specific treatment. Prevalence was calculated as the number of AL patients divided by the number of enrollees on June 30th of each calendar year. Incidence was calculated as the number of patients with AL who were disease-free and enrolled with a health plan for 1 year prior, divided by the ...
