BACKGROUND: In atherosclerosis, monocytes are essential and secrete pro-inflammatory cytokines in response to modified low-density lipoprotein (LDL). Human CD14(++)CD16(-), CD14(++)CD16(+) and CD14(+)CD16(++) monocytes produce different cytokines. The objective of this research was to determine the number of monocyte subsets positives to cytokines in response to native (nLDL) and minimally modified LDL (mmLDL). METHODS: Human monocytes from healthy individuals were purified by negative selection and were stimulated with nLDL, mmLDL or LPS...

BACKGROUND: During previous studies, microRNA-224 (miR-224) was frequently investigated and discovered to be of vital significance to prognosis of patients with various cancers. However, its accurate prognostic value has not been estimated worldwide. Herein, we performed meta-analysis to assess its potential predictive value in a variety of human tumors. METHODS: Qualified researches were identified up to March 1, 2017 through performing online searches in PubMed, EMBASE, Web of Science and Cochrane Database of Systematic Reviews...

BACKGROUND AND AIMS: Preeclampsia is a disorder of pregnancy and is associated with inflammation and altered angiogenesis. The present study examines the effect of micronutrient and omega-3 fatty acid supplementation (individual, as well as combined) on genes involved in inflammation and angiogenesis, as well as global DNA methylation levels in a pregnancy induced hypertension (PIH) rat model. METHODS: Pregnant Wistar rats were randomly assigned to six dietary groups: control, PIH (Pregnancy induced hypertension) Induced; PIH Induced with micronutrient supplements with vitamin B12 (PIHB), folate (PIHF), omega-3 fatty acid (PIHO), and combined supplementation (PIHC) (micronutrients and omega-3 fatty acids)...

BACKGROUND: Little is known about the potential relationship of obesity, adipose tissue and novel adipokines with cardiometabolic risk factors in end-stage renal disease. Zinc-α2-glycoprotein (ZAG) and adipose triglyceride lipase (ATGL) are novel adipokines with proposed desirable effects on inflammation, and lipid and glucose metabolism. The aim of this study was to investigate serum concentrations of ZAG and ATGL, and the relationship of these adipokines with cardiovascular risk factors in normal weight (NW) and obese (OB) patients undergoing hemodialysis...

BACKGROUND AND AIMS: Kidney injury molecule-1 (KIM-1) was identified the most highly upregulated protein in chronic kidney diseases and prolonged KIM-1 expression may be maladaptive. The present study was aimed to investigate urinary, renal and plasma KIM-1 levels and to analyze association between KIM-1 levels with clinical and pathological indexes in adult Henoch-Schönlein purpura (HSP) patients. METHODS: Twenty healthy individuals, 20 HSP patients without nephritis and 35 HSP patients with nephritis were recruited...

Ariana Vargas-Castillo, Rebeca Fuentes-Romero, Leonardo A Rodriguez-Lopez, Nimbe Torres, Armando R Tovar
Obesity is characterized by an excess of white adipose tissue (WAT). Recent evidence has demonstrated that WAT can change its phenotype to a brown-like adipose tissue known as beige/brite adipose tissue. This transition is characterized by an increase in thermogenic capacity mediated by uncoupling protein 1 (UCP1). This browning process is a potential new target for treating obesity. The aim of this review is to integrate the different mechanisms by which beige/brite adipocytes are formed and to describe the physiological, pharmacological and nutritional inducers that can promote browning...

INTRODUCTION: Results from studies investigating relationship between serum lipids and risk of development and progression of diabetic retinopathy (DR) in patients with type 1 diabetes (T1DM) are not consistent. The objective of this study was to explore the relationship between serum lipids and risk of development and progression of nonproliferative diabetic retinopathy (NPDR) in T1DM with normal renal function and with no therapeutic intervention that might influence on retinopathy and serum lipids status...

BACKGROUND AND AIMS: High mobility group box 1 (HMGB1) plays an important role as a pro-inflammatory cytokine that regulates inflammation in various diseases. We hypothesized that hemin might reduce HMGB1 release through the induction of HO-1 in UVB-induced HaCaTs. METHODS: The effects of hemin on the release of HMGB1 in UVB exposure were evaluated. The mechanisms were investigated using various signal inhibitors and small interfering RNA techniques. RESULTS: Treatment with hemin inhibited reactive oxygen species (ROS) in UVB-induced HaCaTs in a dose-dependent manner...

OBJECTIVE: Ghrelin, a gastric hormone with pleiotropic effects modulates vascular function and may influence atherosclerosis. Plasma ghrelin is reduced in the metabolic syndrome (MS), which is also characterized by early atherosclerosis. Ghrelin circulates in acylated (AG) and desacylated (DAG) forms. Their relative impact and that of gender on subclinical atherosclerosis in MS is unknown. AIM OF THE STUDY: To investigate potential associations of total, AG and DAG with carotid atherosclerosis and with gender in the MS...

BACKGROUND AND AIMS: No study has assessed the association between echocardiographic epicardial fat thickness (EFT) and computed tomography (CT)-based epicardial fat volume (EFV) and coronary artery calcification. The aim of this study is to evaluate the association between EFT and EFV and coronary artery calcification. METHODS: Among the 2,299 individuals enrolled in the CArdiometabolic risk, Epicardial fat, and Subclinical Atherosclerosis Registry (CAESAR) study, 2,276 (1,851 men; mean age 45 ± 8...

BACKGROUND: Considering results among previous studies regarding the relationship of red blood cell distribution width (RDW) and all-cause mortality in chronic kidney disease (CKD) patients, we aimed to perform a comprehensive meta-analysis to evaluate the potential association between RDW and all-cause mortality in CKD patients. METHODS: We conducted a systematic literature using electronic databases (PubMed, Ovid, Embase and Web of Science) to identify the studies reporting the association between RDW and all-cause mortality in CKD patients...

BACKGROUND AND AIMS: Age-related macular degeneration (AMD) is the worldwide leading cause of blindness among the elderly, especially in developed countries. The possible association between apolipoprotein E (ApoE) polymorphism (ε2, ε3, ε4) and AMD has been extensively investigated with conflicting results, especially when specifying different clinical phenotypes of AMD. Herein, we conducted a meta-analysis by integrating several recent large-sample studies to verify the effect of ApoE polymorphisms on AMD subtypes...

BACKGROUND AND AIMS: A host of studies investigated the associations between tumor necrosis factor alpha inducible protein 3 (TNFAIP3) gene rs2230926 and rs5029937 polymorphisms and rheumatoid arthritis (RA) susceptibility, but with conflicting findings. Therefore, we explored whether TNFAIP3 gene rs2230926 and rs5029937 polymorphisms are associated with RA by meta-analysis. MATERIAL AND METHODS: We performed out a comprehensive literature search of PubMed, Elsevier, Embase, and CNKI databases to identify relevant studies...

BACKGROUND: NF-κB is a transcription factor involved in cancer stem cells maintenance of many tumors. Little is known about the specific stem-associated upstream regulators of this pathway in ovarian cancer. The Aim of the study was to analyze the role of the canonical and non-canonical NF-κB pathways in stem cells of ovarian cancer cell lines. METHODS: Stem cells were isolated using sorting cytometry. Western blot and RT-PCR were used to quantify protein and messenger RNA levels...

In our continued efforts to search for potent and novel VEGFR-2 inhibitors as antitumor agents, we have identified a series of ureas and amides bearing a oxazolopyrimidine scaffold. AIM OF THE STUDY: To discover more potent VEGFR-2 inhibitors with stronger binding affinity and better physical and chemical properties. METHODS: 23 pyrimidinylacetamide-based ureas were designed and synthesized...

Spinocerebellar ataxia type 2 (SCA2) is part of a group of at least nine dominantly inherited disorders characterized by progressive degeneration of specific neuronal populations and a shared mutational mechanism involving the expansion of a CAG repeat tract in coding regions of novel genes. Efforts have been made to identify biomarkers of disease progression, which would allow timely preventive therapeutic interventions. In the present study was assessed the influence of several genome instability biomarkers on SCA2 clinical severity...
