OBJECTIVE: We report on the preliminary evaluation of a well-designed program, Living with Lymphedema. This longitudinal cohort study assessed patients' quality of life using questionnaires. Our main objective was to evaluate the satisfaction of the patients and their adherence to the program. This was done using a specific questionnaire of satisfaction as well as by noting patients' adherence to the program (number of patients attending all three consultations). The secondary objective was to assess the effect of the program on the patient's quality of life...

In clinical pathology, stent interposition is used to treat vascular disease but can lead to restenosis. Drug-eluting stents (DES) are most commonly used to suppress restenosis but can also have side effects. Therefore, we investigated the anti-proliferative effect and its possible target in vitro and in vivo. We found that Alpinia officinarum Hance (AO) extract efficiently inhibited VSMC proliferation by arresting the transition from the G0/G1 to the S phase via the up-regulation of p27(KIP1) expression. Galangin (GA) was determined to be a significant component of this extract, with the same anti-proliferative activity as the raw extract...

Gardenia fruit has been used in traditional Chinese medicine for thousands of years. A previous study by the present authors indicated that the ethanol extract of gardenia fruits (EEG) primarily contains eight constituents. In the present study, the potential effects of EEG on unilateral ureteral obstruction (UUO)-induced renal interstitial fibrosis were observed in rats. A total of 30 rats were randomly divided into three groups (n=10 each): Sham group, UUO group, and EEG group, which were administered with EEG (200 mg/kg/day) or the same volume of distilled water as a vehicle...

Anaphylaxis is a systemic, life threatening disorder triggered by mediators released by mast cells and basophils activated via allergic (IgE-mediated) or non-allergic (non-IgE-mediated) mechanisms. It is a rapidly evolving, multisystem process involving the integumentary, pulmonary, gastrointestinal and cardiovascular systems. Anaphylaxis and angioedema are serious disorders that can lead to fatal airway obstruction and culminate in cardiorespiratory arrest resulting in hypoxemia and/or shock. Often, these disorders can be appropriately managed in an outpatient setting...

A major hurdle in the field of tissue engineering and regenerative medicine remains the design and construction of larger (> 1 cm(3)) in vitro tissues for biological studies and transplantation. While there has been success in creating three-dimensional (3D) capillary networks, relatively large arteries (diameter >3-5 mm), and more recently small arteries (diameter 500 μm-1 mm), there has been no success in the creation of a living dynamic blood vessel network comprising of arterioles (diameter 40-300 μm), capillaries, and venules...

Robotic technology has been utilized in cardiovascular medicine for over a decade, and over that period, its use has been expanded to percutaneous coronary and peripheral vascular interventions. The safety and feasibility of robotically assisted percutaneous cardiovascular interventions has been demonstrated in studies including simple to complex coronary lesions, and both iliac and femoropopliteal lesions. These reports have shown that robotically assisted PCI significantly reduces operator exposure to harmful ionizing radiation without a detrimental effect on procedural success or clinical efficacy...

Peripheral artery disease (PAD) is an ischemic disease characterized by reduced blood flow to the legs, feet, and hands. Human mesenchymal stem cells (MSCs) are an attractive cell source to treat PAD in regenerative medicine. However, in clinical applications, the use of adult stem cells has several limitations, such as low cell viability and low therapeutic efficiency. In the present study, we described an innovative method of culturing three-dimensional stem cell clusters (AngioclusterTM, AC), demonstrated the potential for ACs to differentiate into vascular cells, and assessed the synergistic effects of ACs and angiopoietin-1 (Ang-1) on angiogenesis in ischemic animal models...

In this study, we engineered mesenchymal stem cells (MSCs) to over-express basic fibroblast growth factor (bFGF) and evaluated its effects on fracture healing. Adipose-derived mouse MSCs were transduced to express bFGF and green fluorescence protein (ADSC(bFGF) -GFP). Closed-femoral fractures were performed with osterix-mCherry reporter mice of both sexes. The mice received 3 × 10(5) ADSCs transfected with control vector or bFGF via intramuscular injection within or around the fracture sites. Mice were euthanized at days 7, 14, and 35 to monitor MSC engraftment, osteogenic differentiation, callus formation, and bone strength...

PURPOSE: Endothelial nitric oxide synthase (eNOS) plays a central role in regulating vascular tone, blood flow, and microvascular permeability. Endothelial dysfunction, including eNOS dysfunction, is an early biomarker of vascular disease. This study aimed to show that myocardial T1 mapping during nitric oxide synthase (NOS) inhibition could assess coronary microvascular eNOS function. METHODS: Wild-type mice, eNOS(-/-) mice, and wild-type mice fed a high-fat diet underwent T1 mapping at baseline and for 20 min after injection of N(G) -nitro-L-arginine methyl ester (LNAME), a NOS inhibitor...

REVIEW
Nicholas T Kruse, Barry W Scheuermann
Stretching is commonly prescribed with the intended purpose of increasing range of motion, enhancing muscular coordination, and preventing prolonged immobilization induced by aging or a sedentary lifestyle. Emerging evidence suggests that acute or long-term stretching exercise may modulate a variety of cardiovascular responses. Specifically, at the onset of stretch, the mechanical deformation of the vascular bed coupled with stimulation of group III muscle afferent fibers initiates a cascade of events resulting in both peripheral vasodilation and a heart rate-driven increase in cardiac output, blood pressure, and muscle blood flow...

Salicornia europaea L. (SE) has been used as folk medicine for the treatment of various diseases such as obesity, diabetes, and cancer. However, its effects on atherosclerotic events in vascular smooth muscle cells (VSMCs) remain unknown. The present study explored the effects of the ethyl acetate fraction of desalted SE hot water extract (SEWEAF) on atherosclerotic responses (especially migration and proliferation) in VSMCs and vascular neointima formation. Treatment with the SEWEAF significantly suppressed the platelet-derived growth factor (PDGF)-BB-induced VSMC migration and proliferation as well the phosphorylation of mitogen-activated protein kinases (MAPKs) such as the p38 MAPK and extracellular signal-regulated kinase (ERK) 1/2...

Directing angiogenic differentiation of mesenchymal stem cells (MSCs) still remains challenging for successful tissue engineering. Without blood vessel formation, stem cell-based approaches are unable to fully regenerate damaged tissues due to limited support for cell viability and desired tissue/organ functionality. Herein, we report in situ cross-linkable gelatin-hydroxyphenyl propionic acid (GH) hydrogels that can induce pro-angiogenic profiles of MSCs via purely material-driven effects. This hydrogel directed endothelial differentiation of mouse and human patient-derived MSCs through integrin-mediated interactions at the cell-material interface, thereby promoting perfusable blood vessel formation in vitro and in vivo...

Angiogenesis, or the generation of new blood vessels from pre-existent ones is a critical process for tumor growth and progression. Hence, the development of angiogenesis inhibitors with therapeutic potential has been a central focus for researchers. Most angiogenesis inhibitors target the Vascular Endothelial Growth Factor (VEGF) pathway, however a number of tyrosine kinase inhibitors (TKIs), immunomodulatory drugs (IMiDs) and inhibitors of the mammalian Target-Of-Rapamycin (mTOR) pathway also display antiangiogenic activity...

Traumatic injury or surgical excision of diseased bone tissue usually require the reconstruction of large bone defects unable to heal spontaneously, especially in older individuals. This is a big challenge requiring the development of biomaterials mimicking the bone structure and capable of inducing the right commitment of cells seeded within the scaffold. In particular, given their properties and large availability, the human adipose-derived stem cells are considered as the better candidate for autologous cell transplantation...
