BACKGROUND AND AIMS: Several studies have confirmed the presence of bacterial DNA in atherosclerotic plaques, but its contribution to plaque stability and vulnerability is unclear. In this study, we investigated whether the bacterial plaque-profile differed between patients that were asymptomatic or symptomatic and whether there were local differences in the microbial composition within the plaque. METHODS: Plaques were removed by endarterectomy from asymptomatic and symptomatic patients and divided into three different regions known to show different histological vulnerability: A, upstream of the maximum stenosis; B, site for maximum stenosis; C, downstream of the maximum stenosis...

INTRODUCTION: Paroxysmal nocturnal hemoglobinuria (PNH) is a disease characterized by the susceptibility of blood cells to attack by the complement system, inducing extracellular vesicle (EV) production. Thromboembolism is the leading cause of death in this condition. Eculizumab, a humanized monoclonal antibody which inhibits the C5 protein of the complement, reduces the thrombotic risk in PNH. MATERIALS AND METHOD: We conducted a pilot, prospective, open-label, longitudinal clinical study with six PNH patients treated with eculizumab...

It has been shown that Granulocyte colony-stimulating factor (G-CSF) has a higher expression in malignant tumors, and anti-G-CSF therapy considerably decreases tumor growth, tumor vascularization and metastasis. Thus, blocking the signaling pathway of G-CSF could be beneficial in cancer therapy. This study is aimed at designing and producing a monoclonal nanobody that could act as an antagonist of G-CSF receptor. Nanobodies are the antigen binding fragments of camelid single-chain antibodies, also known as VHH...

Hypoxia was identified as a mediator of lung fibrosis in patients with chronic obstructive asthma (COA). Overexpression of a disintegrin and metalloproteinase 17 (ADAM 17) and connective tissue growth factor (CTGF) leads to development of tissue fibrosis. However, the signaling pathway in hypoxia-induced ADAM 17 expression remains poorly defined. In this study, we investigated the roles that ribosomal S-6 kinase 1 (RSK1)/CCAAT/enhancer-binding protein β (C/EBPβ)-dependent ADAM 17 expression plays in hypoxia-induced CTGF expression in human lung fibroblasts...

Angiogenesis has been proven to play an important role in the progression of hepatocellular carcinoma (HCC). However, the molecular mechanism underlying HCC angiogenesis is not well understood. In this study, Prospero-related homeobox 1 (PROX1) was identified as a novel pro-angiogenic factor in HCC cell lines and tissues. A strong positive correlation was found between the levels of PROX1 and microvessel density in HCC tissues. Knockdown of PROX1 expression in HCC cells significantly inhibited the in vitro capillary tube formation by human vascular endothelial cells and in vivo angiogenesis of HCC, while overexpression of PROX1 in HCC cells induced the opposite effects...

BACKGROUND: Placental Growth Factor (PGF) is important for wound-healing and vascular collaterogenesis. PGF deficiency is associated with preeclampsia, a hypertensive disease of human pregnancy. Offspring born to preeclamptic mothers display cognitive impairments and brain vascular and neurostructural deviations. Low PGF production during development may contribute to alterations in offspring cerebrovascular beds. Retina is a readily accessible part of the central nervous system with a well-described pattern of vascular development in mice...

Titanium dioxide nanoparticles (TiO2 NPs) have been extensively used in industry, medicine, and daily life, and have shown potential toxic effects for animals or humans. We noted that the effects of TiO2 NPs on the immune system and its mechanism of action in animals or humans have not been elucidated. Thus, mice were exposed to the TiO2 NPs (0, 1.25, 2.5, or 5 mg kg(-1) body weight) for 9 consecutive months. Exposure to TiO2 NPs was accumulated in the thymus, leading to a decrease in body weight and increases in the weight of the thymus or thymus indices...

Vibrio spp. are natural inhabitants of marine and estuarine environments. Vibrio cholerae, Vibrio parahaemolyticus, and Vibrio vulnificus are the major infectious agents for humans. Their densities are affected by environmental factors such as water temperature and salinity. The detailed contribution of each factor still remains to be elucidated. Here we conducted multi-coastal study in a 21-month period to examine relationships between environmental factors and V. cholerae, V. parahaemolyticus and V. vulnificus densities in sea surface water in eight coastal sites of four prefectures in Japan...

Eftrenonacog alfa (Alprolix™) is a recombinant fusion protein comprising human factor IX (FIX) covalently linked to the constant region (Fc) domain of human IgG1 (i.e. rFIXFc). The presence of the Fc domain extends the terminal half-life (t½) of rFIXFc, permitting prolonged treatment intervals. rFIXFc is available for intravenous use for the prophylaxis and treatment of bleeding in patients with haemophilia B. In two multinational, phase III studies in previously treated children, adolescents and adults with severe haemophilia B, rFIXFc prophylaxis resulted in low median annualized bleeding rates (ABRs), and was associated with reductions in median weekly factor consumption and dosing frequency compared with pre-study FIX regimens...

G-CSF is a growth factor that has known neuroprotective effects in a variety of experimental brain injury models. As both antigen-presenting microglia and reactive T cells are key components in the development and progression of EAE, the aim of this study is to investigate the neuroprotective effects of recombinant human G-CSF, as administered in microglia-mediated reactive T cell assay in vitro. Our results indicate that G-CSF treatment has no apparent effect for the resting un-activated microglia. G-CSF pre-protection of microglia increased protective cytokine IL-4 production and effectively inhibited the productions of NO and other inflammatory mediators (IFN-γ, TNF-α, IL-1β, IL-17, and chemokine MCP-1) after LPS stimulation...

Inhibition of acetylcholinesterase (AChE) with organophosphorus compounds has a detrimental effect on human life. Oxime K203 seems to be one of the promising reactivators for tabun-inhibited AChE than (K027, K127, and K628). These reactivators differ only in the linker units between the two pyridinium rings. The conformational analyses performed with quantum chemical RHF/6-31G* level for K027, K127, K203 and K628 showed that the minimum energy conformers have different orientations of the active and peripheral pyridinium rings for these reactivator molecules...

Humans make moral judgments every day, and research demonstrates that these evaluations are based on a host of related event features (e.g., harm, legality). In order to acquire systematic data on how moral judgments are made, our assessments need to be expanded to include real-life, ecologically valid stimuli that take into account the numerous event features that are known to influence moral judgment. To facilitate this, Knutson et al. (in Social Cognitive and Affective Neuroscience, 5(4), 378-384, 2010) developed vignettes based on real-life episodic memories rated concurrently on key moral features; however, the method is time intensive (~1...

OBJECTIVE: Human α1-acid glycoprotein has genetic variants, the F1, S, and A variants, which can be separated isoelectrophoretically. These variants show differences in their affinity of binding to several drugs. In this study, we investigated the factors determining drug binding to these α1-acid glycoprotein genetic variants using disopyramide, warfarin, and tamsulosin as marker compounds. METHODS: Binding of the marker drugs to human α1-acid glycoprotein was determined by ultra-filtration in the presence or absence of various other drugs...

PURPOSE: T-regulatory cells (Tregs) are a sub-population of lymphocytes that act to suppress aberrant immune responses. We investigated changes in the numbers of naïve and terminally differentiated Tregs in the peripheral blood to establish their role in the immuno-suppressive response to prolonged exercise. METHODS: Blood was drawn from seventeen experienced runners (age 40 ± 12 years; height 1.75 ± 0.08 m; mass 71.4 ± 10.8 kg) before, ~1 h after (POST-1h), and on the day following the marathon (POST-1d)...

Insulin-like Growth Factor 1 (IGF-1) is associated with cardiovascular disease, itself a risk factor for hearing impairment, and, in animal studies, molecular evidence suggests a role for IGF-1 in hearing function. However, the link between IGF-1 and the occurrence of hearing impairment is untested in population-based studies of humans. A total of 4390 participants aged ≥50 y (mean [SD] age 64.2 [8.0] years at baseline, 55% women) from the English Longitudinal Study of Ageing provided serum levels of IGF-1 in 2008 and again in 2012...

In vivo electroporation (EP) is used to enhance the uptake of nucleic acids and its association with DNA vaccination greatly stimulates immune responses to vaccine antigens delivered through the skin. However, the effect of EP on cutaneous cell behavior, the dynamics of immune cell recruitment and local inflammatory factors, have not been fully described. Here, we show that intradermal DNA vaccination combined with EP extends antigen expression to the epidermis and the subcutaneous skin muscle in non-human primates...
