The aim of our study was to investigate some early markers of hypertensive target organ damage in hypertensive children and adolescents, and to detect those showing most prominent clinical significance. We included 100 children with essential hypertension (EH) and 50 age-matched healthy control children, and evaluated left ventricular mass (LVM), intima-media thickness in the carotid arteries (IMT), pulse wave velocity (PWV), microalbuminuria, biochemical parameters and some adipokines. Statistically significant differences between the 2 groups were observed for HDL-cholesterol, LDL-cholesterol, triglycerides, insulin, uric acid, glucose, apolipoprotein A1, and total adiponectin...

OBJECTIVE: Transforming growth factor β1 (TGF-β1) is the major cytokine for stimulating endothelial cells (ECs) to transdifferentiate to mesenchymal cells (MCs) in the process known as endothelial-to-mesenchymal transition (EndMT). Recently, TGF-β1-induced EndMT has been implicated in the pathogenesis of atherosclerosis (AS). It has been identified that apolipoprotein A1 (ApoA-I) obstructs TGF-β1-induced endothelial dysfunction, providing a protective effect for ECs and also anti-AS activity...

BACKGROUND: The aim of this study was to analyse the mechanisms that underlie phenotypic quantitative trait loci (QTL) in overfed mule ducks by identifying co-localized proteomic QTL (pQTL). The QTL design consisted of three families of common ducks that were progeny-tested by using 294 male mule ducks. This population of common ducks was genotyped using a genetic map that included 334 genetic markers located across 28 APL chromosomes (APL for Anas platyrhynchos). Mule ducks were phenotyped for 49 traits related to growth, metabolism, overfeeding ability and meat and fatty liver quality, and 326 soluble fatty liver proteins were quantified...

BACKGROUND: Previous studies have demonstrated that hemoglobin-haptoglobin (Hb-Hp) complex plays a role in developing vascular complications in type 2 diabetes mellitus (T2DM). The complexes bind with Apolipoprotein A1 (ApoA1) of high-density lipoprotein (HDL), affecting the function of Lecithin:Cholesterol Acyltransferase (LCAT), and impairing the reverse cholesterol transport mechanism (RCT). This study investigated the influence of Hp phenotypes on serum levels of ApoA1 and LCAT in patients with T2DM...

We investigated the differences between the serum proteomic spectral characteristics of acute myeloid leukemia (AML) patients and those of healthy people. We collected peripheral blood serum samples from 62 AML patients and 15 healthy controls. After removing high-abundance proteins, low-abundance serum proteins were separated using two-dimensional gel electrophoresis to identify differences between AML patients and healthy people. We investigated the different protein dots by mass fingerprint analysis, and evaluated the results using the Masort retrieval program provided by the MSDB protein bank...

INTRODUCTION: Diabetes Mellitus (DM) is always a multifactorial metabolic disorder having a wide range of abnormalities in carbohydrate, lipid and protein metabolism. Dyslipidemia is a natural process of DM causing abnormal variations of different lipoproteins and it is one of the significant risk factors for Cardiovascular Disorder (CVD). There is a need to closely evaluate newer approaches in case of DM because even if dyslipidemia is treated, there is always a risk of CVDs in DM patients because of the hyperglycemia itself...

Anaphylaxis is a life-threatening hypersensitivity reaction. To identify biomarkers for the condition, we assessed serum levels of apolipoprotein (Apo)A and ApoE. We found a reduction of both lipoproteins in anaphylactic mice as well as in orally challenged food allergic patients. We then compared patients after acute anaphylaxis with several control groups (non-allergic, history of allergen-triggered anaphylaxis, acute cardiovascular/febrile reactions). In this unpaired setting, ApoE levels were unaltered, while ApoA1 was reduced in the anaphylactic group...

Premenopausal women are known to have less heart disease than their menopausal counterparts and men. However, there is a rising prevalence of coronary artery disease (CAD) in premenopausal females, which necessitates determination of risk factors that negate the effects of hormonal protection. There are few studies describing the prevalence of traditional and emerging risk factors in premenopausal women with CAD. Thus, our objective was to explore the prevalence of traditional and emerging risk factors and features of coronary lesions in premenopausal women with CAD in an Indian population...

BACKGROUND: High resolution melting (HRM) is a post-PCR technique for variant screening and genotyping based on the different melting points of DNA fragments. The advantages of this technique are that it is fast, simple, and efficient and has a high output, particularly for screening of a large number of samples. APOA1 encodes apolipoprotein A1 (apoA1) which is a major component of high density lipoprotein cholesterol (HDL-C). This study aimed to obtain an optimal quantitative polymerase chain reaction (qPCR)-HRM condition for screening of APOA1 variance...

Despite the recognized role of the ATP-binding Cassette Transporter A1 (ABCA1) in high-density lipoprotein (HDL) metabolism, our understanding of ABCA1 deficiency in human hepatocytes is limited. To define the functional effects of human hepatocyte ABCA1 deficiency, we generated induced pluripotent stem cell (iPSC)-derived hepatocyte-like cells (HLCs) from Tangier disease (TD) and matched control subjects. Control HLCs exhibited robust cholesterol efflux to apolipoprotein A-I (apoA-I) and formed nascent HDL particles...

The aim of the study was to assess correlative risk of progression of inflammatory periodontal lesions, the development of a systemic inflammatory reaction and cardiovascular diseases. The study involved 89 patients with chronic periodontal disease (CPD) of varying degrees. High cardiovascular disease risk was revealed in 8.8% of patients with moderate and 13.3% of patients with severe periodontal disease. It is proved that an additional factor contributing to the pathogenic relationship between periodontal inflammatory changes and the development of cardiovascular disease is systemic inflammatory response with increased hrC-reactive protein >3...

Apolipoprotein A-I (apoA-I) mimetic peptide exerts many anti-atherogenic properties. However, the underlying mechanisms related to the endothelial protective effects remain elusive. In this study, the apoA-I mimetic peptide, D-4F, was used. Proliferation assay, wound healing, and transwell migration experiments showed that D-4F improved the impaired endothelial proliferation and migration resulting from ox-LDL. Endothelial adhesion molecules expression and monocyte adhesion assay demonstrated that D-4F inhibited endothelial inflammation...

Low serum apolipoprotein (Apo) A1 concentrations and high serum ApoB concentrations may be better markers of the risk of cardiovascular disease than high-density lipoprotein (HDL) and low-density lipoprotein (LDL). However, the associations between modifiable lifestyle factors and Apo concentrations have not been investigated in detail. Therefore, this study investigated the associations between Apo concentrations and education, lifestyle factors and dietary intake (macronutrients and 34 food groups). These cross-sectional associations were examined among 24,984 individuals in a Swedish population-based cohort...
