Ya Nan Chu, Hai Bo Zhang, Ze Feng Qin, Jing Ping Gai
As a kind of globally widely distributed soil microorganism, arbuscular mycorrhizal (AM) fungi form the symbiosis with the majority of land plants, which is important for plant nutrition and ecosystem functioning. Few vascular species are considered to be nonmycorrhizal, especially those within the families Amaranthaceae, Chenopodiaceae, Carophyllaceae and Brassicaceae. At present, the interactions between these non-host plants and AM fungi are few and scattered, lacking systematic summary. In this paper, the type of non-host plants, the reason of low mycotrophy, and the effect of AM network formed by neighbor plants on AM fungi colonization on the non-host, and the possible interaction between AM fungi and non-host, as well as the material exchange between plants and AM fungi and their possible ecological functions were reviewed in order to give some new ideas on the function of the nonmycorrhizal plants in the fragile ecosystems...

Since the publication of the 2009 SCAI Expert Consensus Document on Length of Stay Following percutaneous coronary intervention (PCI), advances in vascular access techniques, stent technology, and antiplatelet pharmacology have facilitated changes in discharge patterns following PCI. Additional clinical studies have demonstrated the safety of early and same day discharge in selected patients with uncomplicated PCI, while reimbursement policies have discouraged unnecessary hospitalization. This consensus update: (1) clarifies clinical and reimbursement definitions of discharge strategies, (2) reviews the technological advances and literature supporting reduced hospitalization duration and risk assessment, and (3) describes changes to the consensus recommendations on length of stay following PCI (Supporting Information Table S1)...

FoxO1 has emerged as an important regulator of angiogenesis. Recent work published in this Journal shows that FoxO1 regulates VEGF expression in keratinocytes and is required for angiogenesis in wound healing. Since FoxO1 also regulates CD36 transcription, and endothelial cell differentiation and vascular maturation, this transcription factor may be essential for the formation of functional vascular networks via coupling the regulation of CD36 in vascular endothelial cells under physiological and pathological conditions...

BACKGROUND: Population-based screening and intervention for abdominal aortic aneurysm, peripheral artery disease and hypertension was recently reported to reduce the relative risk of mortality among Danish men by 7 per cent. The aim of this study was to investigate the cost-effectiveness of vascular screening versus usual care (ad hoc primary care-based risk assessment) from a national health service perspective. METHODS: A cost-effectiveness evaluation was conducted alongside an RCT involving all men from a region in Denmark (50 156) who were allocated to screening (25 078) or no screening (25 078) and followed for up to 5 years...

Ivana Gadjanski
In order to engineer biomimetic osteochondral (OC) construct, it is necessary to address both the cartilage and bone phase of the construct, as well as the interface between them, in effect mimicking the developmental processes when generating hierarchical scaffolds that show gradual changes of physical and mechanical properties, ideally complemented with the biochemical gradients. There are several components whose characteristics need to be taken into account in such biomimetic approach, including cells, scaffolds, bioreactors as well as various developmental processes such as mesenchymal condensation and vascularization, that need to be stimulated through the use of growth factors, mechanical stimulation, purinergic signaling, low oxygen conditioning, and immunomodulation...

Significant reductions in blood flow and umbilical diameters were reported in pregnancies affected by intrauterine growth restriction (IUGR) from placental insufficiency. However, it is not known if IUGR umbilical blood vessels experience different hemodynamic wall shear stresses (WSS) compared to normal umbilical vessels. As WSS is known to influence vasoactivity and vascular growth and remodeling, which can regulate flow rates, it is important to study this parameter. In this study, we aim to characterize umbilical vascular WSS environment in normal and IUGR pregnancies, and evaluate correlation between WSS and vascular diameter, and gestational age...

Anti-angiogenesis therapy is an established therapeutic strategy for cancer. The endogenous angiogenic inhibitor angiostatin contains the first 3-4 kringle domains of plasminogen and inhibits both angiogenesis and vascular permeability. We present here a 10-residue peptide, Angio-3, derived from plasminogen kringle 3, which retains the functions of angiostatin in inhibiting both angiogenesis and vascular permeability. NMR studies indicate that Angio-3 holds a solution structure similar to the corresponding region of kringle 3...

As an important site for the production, storage and release of key regulators for vascular function, the vascular adventitia is thought to be a damage sensing tissue in the vascular wall under certain conditions. The adventitial cells are usually the first ones to respond to vascular stress or injury, and consequently affect the structure and function of blood vessel wall. Growing lines of evidence have shown that the vascular adventitia exhibits the earliest and most prominent changes in vascular remodeling due to hypoxia and related pulmonary hypertension and atherosclerosis...

Conventionally rendered optical coherence tomography (OCT) images of the posterior segment contain shadows which influence the visualization of deep structures such as the choroid. The purpose of this study was to determine whether OCT shadow compensation (SC) alters the appearance of the choroid and the apparent choroidal vascularity index (CVI), an OCT-derived estimated ratio of luminal to total choroidal volume. All scans were shadow compensated using a previously published algorithm, binarized using a novel validated algorithm and extracted binarized choroid to estimate CVI...

REVIEW
Ariel A Williams, Hannah M Carl, Scott D Lifchez
Scleroderma is a rare autoimmune connective tissue disorder that often affects the hands. Manifestations in the hands include calcium deposits within the soft tissues that cause pain and may ulcerate through the skin, digital ischemia resulting in chronic wounds and digital gangrene, and joint contracture. Because of the underlying disease, patients with scleroderma have poorly vascularized tissue and a deficient soft tissue envelope, which make surgery particularly challenging. However, when undertaken with care, surgical intervention is often the best option for addressing the disabling hand conditions that so often accompany this disease...

We report spontaneous hemodynamic activity termed "Spontaneous BOLD Waves" (SBWs) detected by BOLD fMRI in Sprague-Dawley rats under medetomidine anesthesia. These SBWs, which lasted several minutes, were observed in cortex, thalamus and hippocampus. The SBWs' correlates were undetectable in electrophysiological recordings, suggesting an exclusive gliovascular phenomenon dissociated from neuronal activity. SBWs were insensitive to the NMDA receptors antagonist MK-801 but were inhibited by the α1-adrenoceptor blocker prazosin...
