The data presented in this article are related to the publication entitled "Iron oxide core oil-in-water nanoemulsion as tracer for atherosclerosis MPI and MRI imaging" (Prévot et al., 2017) [1]. Herein we describe the synthesis and the characteristics of the Superparamagnetic Iron Oxide Nanoparticles (SPION) loaded inside nanoemulsions (NEs). Focus was set on obtaining SPION with narrow size distribution and close to superparamagnetic limit (20 nm) in order to reach a reasonable magnetic signal. Nanoparticles (NPs) of three different sizes were obtained (7, 11 and 18 nm) and characterized using transmission electron microscopy (TEM), X-ray diffraction (XRD), vibrating sample magnetometer (VSM), diffuse reflectance infrared Fourier transform (DRIFT) and thermogravimetric analysis (TGA)...

INTRODUCTION: Damage control laparotomy (DCL) for trauma is thought to be associated with increased abdominal complications. The purpose of this study is to determine the effect of DCL on abdominal complications by comparing two groups of trauma patients: DCL patients who were prospectively adjudicated to potentially being closed at the primary laparotomy (potential DEF or pDEF) and those who underwent definitive laparotomy (DEF). METHODS: The pDEF group was matched to DEF patients according to mechanism of injury, abdominal injury severity, operating room transfusions, and performance of a colon resection...

The complement component 3 (C3) is a central component of complement system. All three pathways converge at formation of C3 convertases and share the terminal pathways of membrane attack complex (MAC) formation. In this study, three isoforms of C3 were discovered in Misgurnus anguillicaudatus, named "C3-1", "C3-2" and "C3-3", respectively. The full-length of C3-1 cDNA sequence was firstly identified and analyzed from dojo loach (Misgurnus anguillicaudatus). The Ma-C3-1 cDNA sequence comprised of 4509 bp encoding 1454 amino acids with a putative signal peptide of 20 amino acid residues...

Bovine mastitis, an inflammation of the udder, results in reduced milk production and poor milk quality. Mastitis is usually, but not always, a response to pathogen infection. High milk yield can produce oxidative stress in the mammary tissue. High milk yield is also known to be associated with bovine mastitis. Thus, in the current study, we hypothesised that oxidative stress increases inflammatory responses in bovine mammary cells. To examine the hypothesis, we produced cellular oxidative stress and investigated resulting inflammatory responses in bovine mammary alveolar cells (MAC-T)...

The functional performance of αI domain α7 helix in β2 integrin activation depends on the allostery of the α7 helix, which axially slides down; therefore, it is critical to elucidate what factors regulate the allostery. In this study, we determined that there were two conservative salt bridge interaction pairs that constrain both the upper and bottom ends of the α7 helix. Molecular Dynamics (MD) simulations for three β2 integrin members of LFA-1 (αL β2 ), Mac-1 (αM β2 ) and αx β2 indicated that the magnitude of the salt bridge interaction is related to the stability of the αI domain and the strength of the corresponding force-induced allostery...

We used circulating tumor cells (CTCs) as biomarkers to evaluate the efficacy of pre-irreversible electroporation (IRE) and post-IRE for unresectable pancreatic cancer (PC). Real-time qPCR was used to detect potential biomarker genes in CTCs, and magnetic-activated cell sorting (MACS) and fluorescence-activated cell sorting (FACS) were performed on 43 patients with PC who underwent IRE. Some patients experienced adverse reactions within 30 days of the operation, including arrhythmia (6.9%), intraoperative transient change of blood pressure (25...

Severe influenza virus infection can lead to life-threatening pathology through immune-mediated tissue damage. In various experimental models, this damage is dependent on T-cells. There is conflicting evidence regarding the role of neutrophils in influenza-mediated pathology. Neutrophils are often regarded as cells causing tissue damage, but in recent years it has become clear that a subset of human neutrophils is capable of suppressing T-cells, which is dependent on Mac-1 (CD11b/CD18). Therefore, we tested the hypothesis that immune suppression by neutrophils can reduce T-cell mediate pathology after influenza infection...

Background: Colorectal signet ring cell (SRC) carcinoma occurs rarely with a poor prognosis. The present study assessed the prognostic factors and predictive value of SRC ratio in colorectal mucinous adenocarcinoma (MAC) with SRCs (MAC-SRC). Patients and methods: A total of 95 consecutive colorectal MAC-SRC patients, confirmed pathologically from February 1987 to December 2015, were analyzed retrospectively in our institute. Clinical characteristics, pathological grade, TNM staging, and SRC ratio were assessed to identify the prognostic factors related to progression-free survival (PFS) and overall survival (OS)...

BACKGROUND AND PURPOSE: Following inflammatory stimuli neutrophils are recruited to sites of inflammation and exert effector functions that often have deleterious effects on tissue integrity, which can lead to organ failure. Btk is expressed in neutrophils, and constitutes a promising pharmacological target for neutrophil mediated tissue damage. Here we evaluate a selective reversible inhibitor of the Bruton's tyrosine kinase (PRN473) for its ability to dampen neutrophil influx via inhibition of adhesion receptor signaling pathways...

Red blood cell transfusions remain one of the cornerstones in supportive care of lower-risk patients with myelodysplastic syndromes. We hypothesized that patients develop oxidant mediated tissue injury through the formation of toxic iron species, caused either by red blood cell transfusions or by ineffective erythropoiesis. We analyzed serum samples from 100 lower-risk patients with myelodysplastic syndromes at six-month intervals for transferrin saturation, hepcidin-25, growth differentiation factor 15, soluble transferrin receptor, non-transferrin bound iron and labile plasma iron in order to evaluate temporal changes in iron metabolism and presence of potentially toxic iron species and their impact on survival...

Melaleuca alternifolia concentrate (MAC) is the refined essential oil of the Australian native plant Melaleuca alternifolia. MAC has been reported to suppress the production of pro-inflammatory cytokines in both murine RAW264.7 macrophages and human monocytes stimulated with lipopolysaccharide (LPS). However, the mechanisms involved in this effect remain unclear. This study aims to delineate the molecular mechanisms that drive the anti-inflammatory activity of MAC and its active component, terpinen-4-ol, in macrophages...

HIV-1 R5 viruses exploit CCR5 as a coreceptor to infect both T-cells and macrophages. R5 viruses that are transmitted or derived from immune tissue and peripheral blood are mainly inefficient at mediating infection of macrophages. In contrast, highly macrophage-tropic R5 viruses predominate in brain tissue and can be detected in cerebral spinal fluid, but are infrequent in immune tissue or blood even in late disease. These mac-tropic R5 variants carry envelope glycoproteins (Envs) adapted to exploit low levels of CD4 on macrophages to induce infection...

The human gut microbiota (GM) has been associated, to date, with various complex functions, essentials for the host health. Among these, it is certainly worth noting the degradation of the so-called microbiota-accessible carbohydrates (MACs), which the GM breaks down through specific enzymes, referred to as carbohydrate-active enzymes (CAZymes). This degradation constitutes the first step in the production of short-chain fatty acids (SCFAs), key microbial small molecules having multiple health-promoting effects for the host organism...
