Green Synthesis of Highly Fluorescent Carbon Dots from Bovine Serum Albumin for Linezolid Drug Delivery as Potential Wound Healing Biomaterial: Bio-Synergistic Approach, Antibacterial Activity, and In Vitro and Ex Vivo Evaluation.

A simple and green approach was developed to produce novel highly fluorescent bovine serum albumin carbon dots (BCDs) via facile one-step hydrothermal treatment, using bovine serum albumin as a precursor carbon source. Inherent blue photoluminescence of the synthesized BCDs provided a maximum photostability of 90.5 ± 1.

Contribution of glutathione peroxidase 1 (Pro200Leu) single nucleotide polymorphism and serum homocysteine levels in the risk of acute myocardial infarction in Egyptians.

Background: Oxidative stress is among the most common risk factors in the pathogenesis of acute myocardial infarction (AMI). Glutathione peroxidase 1 enzyme coded by the GPX1 gene plays an essential role in reducing oxidative stress. Previous studies correlated the GPX1 (Pro200Leu) single nucleotide polymorphism (SNP) with AMI incidence.

Megalin and cubilin are two receptors that mediate endocytosis of 25-hydroxyvitamin D (25(OH)D) for its final activation by hydroxylation. The aim of the present study was to evaluate the association of polymorphisms in megalin (rs2075252 and rs4668123) and cubilin (rs1801222 and rs12766939) with the circulating serum levels of 25(OH)D and with the early incidence of acute coronary syndrome (ACS) in Egyptians. The study included 328 subjects; 185 ACS patients aged between 27 and 60 years, and 143 healthy age-matched controls.

Contribution of and genetic variations to the incidence of acute coronary syndrome and to vitamin D serum level.

Cardiovascular diseases remain a major public health burden worldwide. It was reported that vitamin D protects the cardiovascular system through several mechanisms mainly by hindering atherosclerosis development. Genetic variations in vitamin D metabolic pathway were found to affect vitamin D levels.

Association of manganese superoxide dismutase Ala16Val polymorphism in the incidence of acute myocardial infarction in the Egyptians.

Oxidative stress has been implicated in various diseases including atherosclerosis; the most common pathologic process underlying acute myocardial infarction (AMI). The manganese superoxide dismutase (MnSOD) antioxidant enzyme affords the major defense against reactive oxygen species (ROS) within the mitochondria. MnSOD Alanine16Valine (A16V) single nucleotide polymorphism (SNP) has been shown to decrease MnSOD detoxification activity.

The Association of Fractalkine Receptor (T280M) Polymorphism in the Pathogenesis of Acute Coronary Syndrome in the Egyptian Population.

Background: Fractalkine (FKN) in its free and membrane bound-forms and its receptor CX3CR1are reported to have an atherosclerotic effect. The relationship of Single Nucleotide Polymorphisms (SNPs) in FKN and CX3CR1genes with the Coronary Artery Disease (CAD) risk showed conflicting results in different populations. The aim of this study was to investigate the influence of CX3CR1 threonine 280 methionine (T280M) polymorphism in the predisposition of Acute Coronary Syndrome (ACS) in Egyptians.

AGXT2 and DDAH-1 genetic variants are highly correlated with serum ADMA and SDMA levels and with incidence of coronary artery disease in Egyptians.

Dimethylarginine aminodehydrolase (DDAH1) and alanine glyoxylate aminotransferase2 (AGXT2) are two enzymes that contribute in asymmetric dimethylarginine (ADMA) and symmetric dimethylarginine (SDMA) metabolism. Hence they affect production and bioavailability of eNOS-derived nitric oxide (NO) and consequently healthy blood vessels. The major aims of the current study were to investigate the association of genetic variants of AGXT2 rs37369, AGXT2 rs16899974 and DDAH1 rs997251 SNPs with incidence of coronary artery disease (CAD) in Egyptians and to correlate these variants with the serum levels of ADMA and SDMA.

C(-260)T Polymorphism in CD14 Receptor Gene of Egyptians with Acute Myocardial Infarction.

Background: Despite the significance of the traditional risk factors, recently published studies have suggested that inflammatory processes and variations in the genetics of the inflammatory system may participate in the initiation of atherosclerosis and its complications.

Objective: To investigate the possible association between CD14 C(-260)T (rs2569190) gene polymorphism and the risk of acute myocardial infarction in the Egyptian population.

Methods: We enrolled 100 acute myocardial infarction patients in addition to 107 healthy controls.

Genetic Variants of CYP2R1 Are Key Regulators of Serum Vitamin D Levels and Incidence of Myocardial Infarction in Middle-Aged Egyptians.

Background: Myocardial Infarction (MI) is one of the leading causes of morbidity and mortality in Egypt and worldwide. Vitamin D deficiency has long been linked to incidence of cardiovascular diseases. Several factors were reported to contribute to serum vitamin D level including exposure to sunlight.

Association of Thrombospondin-1 (N700S) and Thrombospondin-4 (A387P) Gene Polymorphisms with the Incidence of Acute Myocardial Infarction in Egyptians.

Background: Thrombospondin (TSP) 1 and 4 are extracellular matrix glycoproteins that me- diate cell proliferation, platelet aggregation and inflammatory response. Conflicting data addressed the possible contribution of TSP-1 and TSP-4 gene polymorphisms to acute myocardial infarction (AMI).

Linking polymorphisms in genes coding for Cx and coronary artery disease (CAD) risk showed conflicting results in different populations.

The Role of Nitric Oxide from Neurological Disease to Cancer.

Until the beginning of the 1980s, nitric oxide (NO) was just a toxic molecule of a lengthy list of environmental pollutants such as cigarette smoke and smog. In fact, NO had a very bad reputation of being destroyer of ozone, suspected carcinogen and precursor of acid rain. However, by the early 1990s it was well recognized by the medical research community.
