PEO-b-PCL grafted niosomes: the cooperativilty of amphiphilic components and their properties in vitro and in vivo

In this study, we designed and developed systems composed of non-ionic surfactants i.e. Tween 80, Span 80 and cholesterol with and without poly(ethylene oxide)-b-poly(ε-caprolactone) (PEO-b-PCL) block copolymer, using different molar ratios of the above components. The nanosystems were formed by the thin-film hydration method with purified water as dispersion medium. Several physicochemical techniques were utilized in order to study the physicochemical and morphological characteristics of the prepared assemblies. The results showed that the presence of the block copolymer alters significantly the size and morphology of neat surfactant/cholesterol niosomes. The ageing studies also revealed that the stability is strongly dependent on the nature and the molar ratios of the components. Moreover, neither of the studied nanosystems exhibited elevated signs of cellular toxicity in vitro nor acute systemic toxicity in vivo short-term experiments. This investigation covers a new field of drug delivery platforms those of niosomes composed by different biomaterials i.e. surfactants and block copolymers.Graphical abstract

We describe the compositional complexity of HDL particles beyond their cholesterol cargo and focus on their role in lipid transport. We discuss the evidence regarding novel HDL functions, including effects on glucose metabolism, and speculate on the implications for type 2 diabetes. HDL cholesterol is an imperfect biomarker of a highly complex and multifunctional lipid transport system, and we should now consider how new HDL markers more causally linked to cardiovascular complications could be adapted for clinical use. In the absence of a superior alternative, HDL cholesterol generally has value as a component of primary c...

The objective of this study was to determine the effects of date vinegar made from date pulp and pits on the serum lipid profile and inflammatory biomarkers of mildly hypercholesterolemic adults. Seventy-six subjects with mildly raised total cholesterol and LDL cholesterol were enrolled. Participants ingested 30 mL of either date vinegar or placebo daily together with their normal diets. Plasma lipids, inflammatory biomarkers, carotenoids, potassium, folic acid, urea and creatinine were measured at baseline after 4 weeks and after treatment. These results suggest that the date vinegar improved several serum lipid pr...

Authors: Kotlęga D, Gołąb-Janowska M, Meller A, Bajer-Czajkowska A, Zembroń-Łacny A, Nowacki P, Banach M Abstract Introduction: Statins are widely used in stroke patients. The AHA/ASA guidelines recommend aggressive statin therapy in atherosclerotic stroke patients. Their beneficial effects are due to both their hypolipemic and pleiotropic properties. The aim of this study was to establish potential benefits from statin use in ischemic stroke patients with the diagnosis of atrial fibrillation (AF). Material and methods: Ischemic stroke patients with AF were enrolled in the study. Group I, the statin group ...

This study assessed blood parameters of lipid metabolism and markers of oxidative stress in patients with psoriasis and PSA. Material and methods: The study included 93 patients with psoriasis (31 patients with PSA and psoriasis, 62 patients with psoriasis vulgaris), and 60 healthy, age-matched controls. Serum concentrations of the glucose and the following lipid metabolism parameters were measured: triglycerides (TG), total cholesterol (TC), low-density lipoproteins (LDL), very low-density lipoproteins (VLDL), high-density lipoproteins (HDL), and apolipoproteins A and B (ApoA, ApoB). Oxidative status was determined as...

Authors: Wrzosek M, Sawicka A, Wrzosek M, Piątkiewicz P, Tałałaj M, Nowicka G Abstract Introduction: Interaction between obesity and genetic factors involved in the regulatory pathways of glucose homeostasis may play a significant role in diabetes development in the obese. The aim of this study was to investigate the associations between the TCF7L2 rs7903146 polymorphism, adiponectin levels, age at onset of obesity and the occurrence of type 2 diabetes (T2D) in a sample of obese Polish adults. Material and methods: A total of 474 unrelated obese subjects were included in this study. Real-time PCR was used to...

Congestive heart failure caused by silent ischemia and silent myocardial infarction : Diagnostic challenge in type 2 diabetes. Herz. 2019 Mar 21;: Authors: Valensi P, Meune C Abstract In asymptomatic patients with type 2 diabetes (T2D), the prevalence of silent myocardial infarction on routine electrocardiograms is about 4% while for silent myocardial ischemia it is 20-30%. Some studies showed that silent myocardial infarction is associated with an increased risk of incident heart failure (HF), whereas no prospective study has ever reported such a risk in patients with silent myocardial ...
