INTRODUCTION: Sleepiness and cardiovascular disease share common molecular pathways; thus, genetic risk factors for sleepiness may also predict cardiovascular disease risk. This study explored the associations between subjective sleepiness and single-nucleotide polymorphisms (SNPs) in candidate genes within oxidative stress, inflammatory, and neuronal pathways, which may contribute to sleepiness and downstream cardiovascular disease risk: Cytochrome B-245, Alpha Polypeptide (CYBA), Cytochrome B-245, Beta Polypeptide (CYBB), Neutrophil Cytosolic Factor (NCF2), Tumor Necrosis Factor-Alpha (TNFA), and Phosphodiesterase 4D (PDE4D)...

A catecholamine neurotransmitter, dopamine (DA), is suggested to be linked to the pathology of dementia; however, the involvement of DA and its structural analogues in the pathogenesis of Alzheimer's disease (AD), the most common form of dementia, composed of multiple pathogenic factors has not been clear. Herein, we report that DA and its rationally designed structural derivatives (1-6) based on DA's oxidative transformation are able to modulate multiple pathological elements found in AD [ i.e., metal ions, metal-free amyloid-β (Aβ), metal-bound Aβ (metal-Aβ), and reactive oxygen species (ROS)], with demonstration of detailed molecular-level mechanisms...

The opportunistic fungal pathogen Candida albicans frequently causes diseases such as oropharyngeal candidiasis (OPC) in immunocompromised individuals. Although it is well appreciated that the cytokine IL-17 is crucial for protective immunity against OPC, the cellular source and the regulation of this cytokine during infection are still a matter of debate. Here, we directly visualized IL-17 production in the infected tongue of experimentally infected mice, thereby demonstrating that this key cytokine is expressed by three complementary subsets of CD90+ leukocytes: RAG-dependent αβ and γδ T cells, as well as RAG-independent ILCs...

OBJECTIVE: Vascular remodeling associated with increased extracellular matrix (ECM) may precede hypertension. Procollagen type III N-terminal propeptide (PIIINP) and collagen type I carboxy-terminal telopeptide (ICTP) reflect collagen turnover and are important in ECM remodeling. PIIINP and ICTP are increased in cardiovascular diseases (CVD). We hypothesized that PIIINP and ICTP among normotensives predict incident hypertension. METHODS: We included 1252 Multi-Ethnic Study of Atherosclerosis participants with mean age 58...

Neutrophil-to-lymphocyte ratio (NLR) has been shown to be prognostic in several solid malignancies. There are limited data regarding its value during novel therapies in patients with melanoma. The aim of the study was to assess the practical utility of this ratio in patients with BRAF-mutant melanoma treated with a combination of BRAF and MEK inhibitors (BRAFi/MEKi). We included 215 patients with inoperable or metastatic melanoma who underwent BRAFi/MEKi treatment between October 2015 and June 2017. Baseline NLR and other complete blood count-derived inflammatory markers were tested for association with overall survival and progression-free survival in univariate and multivariate models...

BACKGROUND: Literature data on hepcidin (H) level - the main regulator of systemic iron homeostasis in patients with chronic heart failure (CHF) - are contradictory. Relationships of H with markers of inflammation elevated level of which is characteristic of CHF are insufficiently studied. The latter problem remains practically unexplored in elderly and very old patients with CHF. AIM: to study the role of H in formation of anemia of chronic disease (ACD) and iron deficiency anemia (IDA) in elderly and very old patients with CHF...

Biologic aging results in a chronic inflammatory condition, termed inflammaging, which establishes a risk for such age-related diseases as neurocardiovascular diseases; therefore, it is of great importance to develop rejuvenation strategies that are able to attenuate inflammaging as a means of intervention for age-related diseases. A promising rejuvenation factor that is present in young blood has been found that can make aged neurons younger; however, the component in the young blood and its mechanism of action are poorly elucidated...

Approximately 30% of patients with ulcerative colitis require a colectomy during their disease course. This substantially reduces colorectal cancer risk, although it is still possible to develop colorectal neoplasia in the remaining rectum. Although clear and well-accepted surveillance guidelines exist for patients with inflammatory bowel disease with an intact colon, specific surveillance recommendations following colectomy are less clear. Here, we aim to summarize the prevalence, incidence, and risk factors for developing colorectal cancer in patients with inflammatory bowel disease who underwent subtotal colectomy with a permanent end ileostomy and rectal stump, or with ileorectal anastomosis...

Tuberculosis is chronic respiratory infectious disease and is caused by the infection of Mycobacterium tuberculosis (M.tb). Macrophages play an important role in host immune response against M.tb infection, which is regulated by various factors, including microRNAs (miRNAs). The present study aimed to examine the in vitro functional role of miR-1178 in mycobacterial survival and inflammatory responses induced by M.tb infection in human macrophages. Our results showed that M.tb infection increased the expression of miR-1178 in human macrophages (HTP-1 and U937 cells) in a concentration- and time-dependent manner...

Placement of dental implants initiates inflammatory foreign body response, in which macrophages play a central role and affect the subsequent tissue healing process such as bone formation. The purpose of this study was to fabricate phosphatidylserine (PS)-containing supported lipid bilayers (SLBs) on a titanium surface to regulate the polarization of macrophages, a critical factor that affects following tissue healing and regeneration. The fluorescent recovery after photobleaching (FRAP) images showed that the percentage of PS had a critical influence on the fluidity, and 20% PS had the highest fluidity...

Oxidative stress and inflammation are critically implicated in ambient fine particulate matter (mean diameter < 2.5 μm; PM2.5 )-induced lung injury. Autophagy, playing a crucial role in various physiopathological conditions, modulates cellular homeostasis and stress adaptation. Resveratrol is a phytoalexin that exerts potent antioxidant effects on cardiopulmonary diseases. To date, the mechanisms by which resveratrol protects against PM2.5 remain to be elucidated. In the present study, we investigated the effect of resveratrol on PM2...

Sepsis is a severe and progressive disease characterized by systemic inflammatory response syndrome (SIRS). CD40 serves as a vital link between immune response and inflammation. This study was designed to investigate the potential association between a functional single-nucleotide polymorphism (SNP) of CD40 (rs1883832) and susceptibility to sepsis. We first performed a case-control study to explore the relationship between the CD40 rs1883832 polymorphism and sepsis. CD40 mRNA expression and protein expression were determined by real-time PCR and western blotting, respectively, in peripheral blood mononuclear cells (PBMCs) from sepsis patients and healthy controls...

Formaldehyde (FA) is a familiar indoor air pollutant found in everything from cosmetics to clothing, but its impact on the middle ear is unknown. This study investigated whether FA causes cytotoxicity, inflammation, or induction of apoptosis in human middle ear epithelial cells (HMEECs). Cell viability was investigated using the trypan blue assay and a cell counting kit (CCK-8) in HMEECs treated with FA for 4 or 24 h. The expression of genes encoding the inflammatory cytokine tumor necrosis factor alpha (TNF- α ) and mucin (MUC5AC) was analyzed using RT-PCR...

Bone marrow-derived mesenchymal stem cells (MSCs) have therapeutic effects in experimental models of lung injury. Hypoxia-inducible factor-1 alpha (HIF-1α) is a transcriptional regulator that influences cellular metabolism, energetics, and survival under hypoxic conditions. The current study investigated the effects of stabilizing HIF-1α on the therapeutic capacity of MSCs in an experimental mouse model of bacterial pneumonia. HIF-1α stabilization was achieved by the small molecule prolyl-hydroxlase inhibitor, AKB-4924 (Aerpio Therapeutics, Inc...

The blood-brain barrier (BBB), an interface between the systemic circulation and the nervous system, can be a target of cytokines in inflammatory conditions. Pro-inflammatory cytokines tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) induce damage in brain endothelial cells and BBB dysfunction which contribute to neuronal injury. The neuroprotective effects of α-melanocyte stimulating hormone (α-MSH) were investigated in experimental models, but there are no data related to the BBB. Based on our recent study, in which α-MSH reduced barrier dysfunction in human intestinal epithelial cells induced by TNF-α and IL-1β, we hypothesized a protective effect of α-MSH on brain endothelial cells...
