MitoAKAPs (mitochondrial A kinase anchoring proteins), encoded by the Akap1 gene, regulate multiple cellular processes governing mitochondrial homeostasis and cell viability. Although mitochondrial alterations have been associated to endothelial dysfunction, the role of mitoAKAPs in the vasculature is currently unknown. To test this, postischemic neovascularization, vascular function, and arterial blood pressure were analyzed in Akap1 knockout mice (Akap1-/- ) and their wild-type (wt) littermates. Primary cultures of aortic endothelial cells (ECs) were also obtained from Akap1-/- and wt mice, and ECs migration, proliferation, survival, and capillary-like network formation were analyzed under different experimental conditions...

Ultrafast compound Doppler imaging based on plane-wave excitation (UCDI) can be used to evaluate cardiovascular diseases using high frame rates. In particular, it provides a fully quantifiable flow analysis over a large region of interest with high spatio-temporal resolution. However, the pulse-repetition frequency (PRF) in the UCDI method is limited for high-velocity flow imaging since it leverages between the number of plane-wave angles (<i>N</i>) and acquisition time. In this paper, we present high PRF ultrafast sliding compound Doppler imaging method (HUSDI) to improve quantitative flow analysis...

BACKGROUND: Aortoiliac occlusive disease, which is also referred to as Leriche syndrome, is a chronic atherosclerotic occlusive disease that occurs at the level of the aortic bifurcation. It is often thought to present with a triad of clinical symptoms: (1) intermittent lower extremity vascular claudication, (2) impotence, and (3) weak/absent femoral pulses. CASE PRESENTATION: We report a case of a 47-year-old Caucasian woman who presented with an acute inferior ST-elevation myocardial infarction...

Patients with critical limb ischemia necessitate immediate intervention to restore blood flow to the affected limb. Endovascular procedures are currently preferred for these patients. We describe the case of an 80-year-old female patient who presented to our department with ischemic rest pain and ulceration of the left limb. The patient had history of left femoral popliteal bypass surgery, femoral thromboendarterectomy and patch angioplasty of the same limb 2 years ago. Doppler sonography and magnetic resonance angiography revealed an occlusion of the left superficial femoral artery (SFA) and popliteal artery and of all three infra-popliteal arteries...

OBJECTIVES: Cardiogenic shock constitutes the final common pathway of cardiac dysfunction associated with tissue hypoperfusion and organ failure. Besides treatment of the underlying cause, temporary mechanical circulatory support serves as a supportive measure. Extracorporeal membrane oxygenation can effectively prevent hypoxemia and end-organ dysfunction, but knowledge about patient selection, risks, and complications remains sparse. DATA SOURCES: Clinical observation...

The current guidelines following an acute coronary syndrome recommend dual anti-platelet therapy (aspirin plus a P2Y12 antagonist) alongside lifestyle modifications, including more regular physical activity. It is currently unknown if regular exercise affects the pharmacology of dual anti-platelet therapy. AIM: To explore how exercise-induced improvements in vascular and platelet function affect the efficacy of dual anti-platelet therapy, in a cross-sectional study of men with different physical activity level (training status)...

OBJECTIVE: Peripheral arterial disease can cause not only ischemia but also skeletal muscle damage. It has been known that macrophages (MPs) play an important role in coordinating muscle repair; however, phenotype transition of monocyte-MP in ischemic muscle has not been well defined. Hence, the purpose of this study was to examine the temporal recruitment of MPs and to explore their therapeutic effect on ischemic muscle regeneration. METHODS: Unilateral femoral artery excision was performed on C57BL/6 mice...

OBJECTIVE: Cardiopulmonary bypass (CPB) and deep hypothermic circulatory arrest (DHCA) are commonly used in cardiac surgery. However, the mortality and morbidity are still high in practice. Developing novel protective stategies and elucidating the underlying mechanisms for the pathophysiological consequences of DHCA have been hampered because of the absence of a satisfactory recovery animal model. The aim of this study was to establish a novel and safe DHCA model without blood priming in rats to study the pathophysiology of potential complications...

OBJECTIVE: Recent studies demonstrate that microRNAs show promising potential, including angiogenesis, in therapeutic intervention. MicroRNA-126 (miR-126) is reported to regulate angiogenesis by blocking Sprouty-related EVH1 domain-containing protein 1 (SPRED1), an endogenous inhibitor of vascular endothelial cell growth factor. In this study, we investigated the angiogenic effects of the sustained release of miR-126 loaded with poly lactic-co-glycolic acid (PLGA) nanoparticles (NPs) in a murine hindlimb ischemia model...

Blacks have the highest prevalence of hypertension, putting them at greater risk of cardiovascular disease and death. Previous studies have reported that, relative to whites, healthy black men have augmented pressor responses to sympathoexcitatory stressors. Although important, these studies do not inform about the resting state and the influence of spontaneous changes in resting muscle sympathetic nerve activity (MSNA). Likewise, little is known about the transduction of MSNA into a vascular response at rest on a beat-to-beat basis...

Successful raising of a distally based anterolateral thigh (dALT) flap mainly depends on a well-developed lateral circumflex femoral artery (LCFA) descending branch and an intact vascular connection between the descending branch and the vascular network of the knee. However, in some clinical scenarios, the descending branch is hypoplastic or the vascular connection of the knee is compromised. We present six cases of using dALT flaps in soft tissue defect reconstruction of the knee with either of the above-mentioned conditions...

Femoro-femoral cardiopulmonary bypass (CPB) followed by deep hypothermic circulatory arrest is one of the modalities used for ascending aortic pseudoaneurysm repair to achieve cardiac unloading and to avoid severe hemorrhage due to the risk of rupture during the sternal entry. However, due to the limited size of the cannulas, it can be challenging to achieve total cardiopulmonary support. Therefore, despite the achievement of total cardiopulmonary support, the heart may still be able to eject antegrade blood flow that meets the retrograde blood flow from the arterial side of the CPB...

During supramaximal exercise, exacerbated at exhaustion and in hypoxia, the circulatory system is challenged to facilitate oxygen delivery to working tissues through cerebral autoregulation which influences fatigue development and muscle performance. The aim of the study was to evaluate the effects of different levels of normobaric hypoxia on the changes in peripheral and cerebral oxygenation and performance during repeated sprints to exhaustion. Eleven recreationally active participants (six men and five women; 26...
