Triclosan (TCS), one of the important bactericides, is widely used in personal care products, and its chronic exposure leads to severe toxic effects on the growth and development of blood vessels in zebrafish (Danio rerio). Herein, we screened out three differentially expressed miRNAs (miR-181a-5p, miR-132-3p and miR-128-3p) by sequencing and qRT-PCR analyses of 4-96-hpf TCS-exposed zebrafish, among which miR-181a-5p was found to regulate many signaling pathways involved in fatty acid biosynthesis and phosphatidylimositol signaling systems...

Recently, exosomes have been emerged as promising drug delivery carriers, while certain tissues are intrinsically resistant to exosomes. Therapeutically improving the drug delivery efficiency in these tissues/organs would certainly broaden the potential application of exosomes in future. Ultrasound-targeted microbubble destruction (UTMD) is a promising technique for non-invasive, targeted drug delivery. In this study, we explore the possibility that UTMD assists exosome delivery in these intrinsically resistant tissues...

INTRODUCTION: Klippel-Trenaunay syndrome (KTS) and related overgrowth syndromes are rare conditions that often present to academic pediatric units and multidisciplinary vascular anomaly clinics. These conditions are commonly associated with abnormalities of the superficial and deep venous structures and carry an increased risk of venous thromboembolism. METHODS: A retrospective chart review was completed of all patients treated at Johns Hopkins All Children's Hospital with endovenous laser therapy (EVLT) for management of dilated embryonic veins in the setting of limb overgrowth...

Acute liver injury is a critical syndrome ascribed to prevalent death of hepatocyte and imperatively requires a liver transplantation. Such methodology is certainly hampered due to deficit of healthy donors. In this regard, stem cells-based regenerative therapies are attractive in repairing injured tissues and organs for medical applications. However, it is crucial to understand the migration, engraftment and regeneration capabilities of transplanted stem cells in the living animal models. For the first time, we demonstrate rapid labeling of umbilical cord-derived mesenchymal stem cells (MSCs) with near-infrared (NIR) fluorescent CuInS2-ZnS nanocrystals (CIZS-NCs) to develop an innovative nano-bioconjugates (MSCs-CIZS-NBCs) that exhibit 98% labeling efficiency...

Sclerotherapy continues to be the treatment of choice for varicose veins in the legs. However, isolated treatment using microfoam or lasers requires a high number of sessions to eliminate them. In 2013, we published results about the efficacy and safety 3 years after the combined treatment with microfoam injections and subsequent application of Nd:YAG laser. The aim of this paper is to clinically evaluate the treatment of varices in a control visit after 5 years, when polidocanol microfoam is used and is immediately irradiated in the tissue with 1064-nm Nd:YAG laser beam...

Microglia represent resident immune cells of the central nervous system (CNS), which have been shown to be involved in the pathophysiology of practically every neuropathology. As microglia were described to participate in the formation of the astroglial glia limitans around CNS vessels, they are part of the neurovascular unit (NVU). Since the NVU is a highly specialized structure, being functionally and morphologically adapted to differing demands in the arterial, capillary, and venous segments, the present study was aimed to systematically investigate the microglial contribution to the glia limitans along the vascular tree...

INTRODUCTION: Endovenous ablations are the new standard procedures for treatment of great saphenous vein reflux including endovenous laser ablation (EVLA), radio frequency ablation (RFA), endovenous steam ablation (EVSA), mechanochemical ablation (MOCA), cyanoacrylate injection and ultrasound-guided foam sclerotherapy (UGFS). EVLA and RFA have demonstrated similar anatomical success for short-term outcome, but results are controversial for longer term (≥5 years). Additional evidences from randomised controlled trials have been published...

A 43-year-old lady presented with painful, loss of vision in the right eye 2 weeks after cataract surgery. This is on a background of previous central retinal vein occlusion in the right eye and bilateral diabetic retinopathy. Her past medical history included mixed connective tissue disease for which she is on systemic immunosuppressants. Ocular examination revealed significant corneal oedema, a shallow anterior chamber with an intraocular pressure of 45 mmHg. Intraocular pressure lowering medications were administered and repeat examination identified a fine fibrinous membrane attached to the pupillary margin with a substantial third space that had formed between the posterior edge of the membrane and the anterior lens surface...

Residues of harmful chemicals in fruit and vegetables pose risks to human health. Ordinary laser-induced breakdown spectroscopy (LIBS) techniques are unsatisfactory for detecting harmful chemicals in fruit and vegetables. In this study, we applied metal nanoparticles to fruit and vegetables samples to improve the ability of LIBS to detect trace pesticide and heavy metal residues in the samples. The nanoparticle-enhanced LIBS technique gave pesticide residue detection limits for fruit and vegetables two orders of magnitude lower than achieved using standard LIBS and heavy metal detection limits markedly better than achieved using standard LIBS...

OBJECTIVES: Exosomes, as important players in intercellular communication due to their ability to transfer certain molecules to target cells, are believed to take similar effects in promoting bone regeneration with their derived stem cells. Studies have suggested that umbilical cord mesenchymal stem cells (uMSCs) could promote angiogenesis. This study investigated whether exosomes derived from uMSCs (uMSC-Exos) could enhance fracture healing as primary factors by promoting angiogenesis...

Central retinal vein occlusion (CRVO) is an intractable disease that causes visual acuity loss with retinal ischemia, hemorrhage, and edema. In this study, we developed an experimental CRVO model in mice and evaluated the therapeutic potential of the pleiotropic peptide adrenomedullin (ADM) and its receptor activity-modifying protein 2 (RAMP2). The CRVO model, which had phenotypes resembling those seen in the clinic, was produced by combining i.p. injection of Rose bengal, a photoactivator dye enhancing thrombus formation, with laser photocoagulation...
