Abstract
According to the interaction of nanoparticles with biological systems, enthusiasm for nanotechnology in biomedical applications has been developed in the past decades. Fe2O3 nanoparticles, as the most stable iron oxide, have special merits that make them useful widely for detecting diseases, therapy, drug delivery, and monitoring the therapeutic process. This review presents the fabrication methods of Fe2O3-based materials and their photocatalytic and magnetic properties. Then, we highlight the application of Fe2O3-based nanoparticles in diagnosis and imaging, different therapy methods, and finally, stimulus-responsive systems, such as pH-responsive, magnetic-responsive, redox-responsive, and enzyme-responsive, with an emphasis on cancer treatment. In addition, the potential of Fe2O3 to combine diagnosis and therapy within a single particle called theranostic agent will be discussed.

Abstract
Nanotechnology could offer a new complementary strategy for the treatment of vascular diseases including coronary, carotid, or peripheral arterial disease due to narrowing or blockage of the artery caused by atherosclerosis. These arterial diseases manifest correspondingly as angina and myocardial infarction, stroke, and intermittent claudication of leg muscles during exercise. The pathogenesis of atherosclerosis involves biological events at the cellular and molecular level, thus targeting these using nanomaterials precisely and effectively could result in a better outcome. Nanotechnology can mitigate the pathological events by enhancing the therapeutic efficacy of the therapeutic agent by delivering it at the point of a lesion in a controlled and efficacious manner. Further, combining therapeutics with imaging will enhance the theranostic ability in atherosclerosis. Additionally, nanoparticles can provide a range of delivery systems for genes, proteins, cells, and drugs, which individually or in combination can address various problems within the arteries. Imaging studies combined with nanoparticles helps in evaluating the disease progression as well as the response to the treatment because imaging and diagnostic agents can be delivered precisely to the targeted destinations via nanocarriers. This review focuses on the use of nanotechnology in theranostics of coronary artery and peripheral arterial disease.

Abstract
The aims of this study are to prepare quaternized xylan-Fe2O3 (QX-Fe2O3) core/shell nanocomposites and explore their potential application in the biomedical fields. γ-Fe2O3 nanoparticles synthesized by a facile solvothermal process are coated with QX via reverse microemulsion method and further modified by polylysine (PLL) and folic acid (FA) to prepare PLL-QX-Fe2O3 and FA-QX-Fe2O3 nanoparticles. An obvious strong absorption of γ-Fe2O3 at 580 cm-1 in the spectra of QX-Fe2O3 is observed, the Fe element content of QX-Fe2O3 is 30-75 μg/mL and the saturation magnetization of QX-Fe2O3 nanoparticles is 1.49 emu/g. The γ-Fe2O3 and QX-Fe2O3 nanoparticles are of regular sphericity with diameter of 50-100 nm and 60-150 nm, respectively. The highest zeta potential of QX-Fe2O3 nanoparticles is -41 mV, and the PLL-QX-Fe2O3 nanoparticles have a positive potential with a maximum value of 45.2 mV. In addition, FA-QX-Fe2O3 showed excellent performance in T2-weighted Magnetic Resonance (MR) imaging with an r2 value of 190 mM-1S-1. Each nanocomposite has its own inherent properties, which contributes to its versatile utilization and application potential.

Abstract
PURPOSE OF REVIEW This review aims to discuss the existing evidence on the link between atherosclerosis and periodontitis by particularly presenting new findings that link the pathology and therapy of these diseases. Acute vascular ischemic events that can lead to stroke or myocardial infarction are initiated by inflammatory processes leading to rupture or erosion of plaques susceptible to thrombosis ("high risk" or "vulnerable"). These are highly inflamed plaques residing in the media and adventitia that may not be detected by angiography measurments of luminal narrowing. Statistically significant excess risk for atherosclerotic cardiovascular disease has been reported in persons with periodontitis independent of established risk factors. We hypothesized that the systemic pathologic links also represent potential therapeutic links. RECENT FINDINGS We recently demonstrated that periodontal inflammation promotes atherosclerotic plaque inflammation and destabilization. As discrete pathological regions, these plaques with a high susceptibility to rupture can be imaged and differentiated from lower risk plaques. In cholesterol-fed rabbits with periodontal disease, circulating inflammatory mediators were also significantly elevated thereby contributing to "vulnerable blood," a systemic characteristic of high risk for cardiovascular events. New studies show that certain lipid mediators, including lipoxins and resolvins, are potent in preventing and possibly treating a number of inflammation-associated diseases, including periodontitis and vascular inflammation. The concept of the vulnerable patient and the pro-resolving approach open new terrain for discovery of paradigm-changing therapies for the prevention and treatment of two of the most common diseases of man. Importantly, lipoxins and resolvins are natural receptor agonists that do not exhibit the same pro-atherogenic side effects attributed to anti-inflammatory medications (e.g., NSAIDs) but rather coordinate resolution of inflammation and a return to homeostasis.

Synthesis of europium-doped VSOP, customized enhancer solution and improved microscopy fluorescence methodology for unambiguous histological detection. J Nanobiotechnology 2017; 15:71. [PMID: 29017510 PMCID: PMC5634840 DOI: 10.1186/s12951-017-0301-6] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2017] [Accepted: 09/23/2017] [Indexed: 12/03/2022] Open
Abstract
Background Intrinsic iron in biological tissues frequently precludes unambiguous the identification of iron oxide nanoparticles when iron-based detection methods are used. Here we report the full methodology for synthesizing very small iron oxide nanoparticles (VSOP) doped with europium (Eu) in their iron oxide core (Eu-VSOP) and their unambiguous qualitative and quantitative detection by fluorescence. Methods and results The resulting Eu-VSOP contained 0.7 to 2.7% Eu relative to iron, which was sufficient for fluorescent detection while not altering other important particle parameters such as size, surface charge, or relaxivity. A customized enhancer solution with high buffer capacity and nearly neutral pH was developed to provide an antenna system that allowed fluorescent detection of Eu-VSOP in cells and histologic tissue slices as well as in solutions even under acidic conditions as frequently obtained from dissolved organic material. This enhancer solution allowed detection of Eu-VSOP using a standard fluorescence spectrophotometer and a fluorescence microscope equipped with a custom filter set with an excitation wavelength (λex) of 338 nm and an emission wavelength (λem) of 616 nm. Conclusion The fluorescent detection of Eu-doped very small iron oxide nanoparticles (Eu-VSOP) provides a straightforward tool to unambiguously characterize VSOP biodistribution and toxicology at tissue, and cellular levels, providing a sensitive analytical tool to detect Eu-doped IONP in dissolved organ tissue and biological fluids with fluorescence instruments.
