Multiple reaction monitoring mass spectrometry (MRM-MS) analysis of lipid extracts from human carotid endarterectomy and carotid artery samples from young individuals consistently demonstrated the presence of bacterial serine dipeptide lipid classes including Lipid 654, an agonist for human and mouse Toll-like receptor 2, and Lipid 430, the deacylated product of Lipid 654. The relative levels of Lipid 654 and Lipid 430 were also determined in common oral and intestinal bacteria from the phylum Bacteroidetes, and human serum and brain samples from healthy adults...

PURPOSE: Bariatric surgery (BS) promotes carotid intima-media thickness (C-IMT) regression as early as 6 months post-surgery. To verify whether C-IMT regression occurs even earlier, we aimed at the effect of Roux-en-Y gastric bypass (RYGBP) and biliopancreatic diversion (BPD) on C-IMT 1-2 months and 12 months post-surgery. SUBJECTS/METHODS: Prospective trial. BS was performed on 109 patients either with (RYGBP = 42; BDP = 40) or without type 2 diabetes (RYGBP = 27)...

AIM: Limited joint mobility (LJM) of hand, which is one of a complication of diabetic hand, has a close association with diabetic microangiopathy. However, it remains to be elucidated about the relationships between LJM of hand and subclinical atherosclerosis in patients with type 2 diabetes. Therefore, we conducted a cross-sectional study to evaluate the relationships between LJM of hand and carotid intima-media thickness (IMT) and plaque score in patients with type 2 diabetes. METHODS: We evaluated the relationships between LJM of hand, and carotid IMT and plaque score, evaluated by carotid ultrasound examination, in 341 consecutive patients with type 2 diabetes...

Cervical carotid aneurysms are rare, and surgical treatment should be planned for each patient. The authors report 9 cases of cervical carotid aneurysm in 9 patients(mean age, 53.7 years;5 men)who were treated surgically between 2005 and 2014. The aneurysm was located in the internal carotid artery in 6 patients, the common carotid artery in 2 patients, and the carotid bifurcation in 1 patient. Four aneurysms were recurrences after a previous endovascular intervention(parent artery coil embolization, covered stent placement, or stent with coil embolization)...

Iatrogenic cervical internal carotid artery pseudoaneurysm is a rare and potentially lethal complication following tonsillectomy. It can be complicated by thromboembolism, mass effect and eventually may rupture leading to death. Various endovascular treatment options are available for the management of these pseudoaneurysms, including coil embolization, detachable balloon occlusion, or stent graft placement. Parent artery occlusion using detachable balloons can be a therapeutic option in a subset of patients...

BACKGROUND: Hemodialysis (HD) patients have increased risk of cardiovascular disease (CVD). Impaired stem cell health and adipocytokine metabolism may play important roles in the complex pathophysiological mechanisms of CVD in this patient population. We aimed to investigate the relationships between CD133+ cell counts, adipocytokines and parameters of endothelial dysfunction and atherosclerosis in HD patients. METHODS: In 58 chronic HD patients (male/female:28/30, mean age:58 ± 14 years), serum levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), leptin, adiponectin and resistin were measured by ELISA...

The authors describe, for the first time to their knowledge, a case of a congenital macrocystic lymphatic malformation of the orbit with associated venous stasis retinopathy that acutely normalized after drainage and sclerotherapy of the lesion. Prenatal ultrasound revealed prominence of the left orbital soft tissue, and at birth, the patient was noted to have unilateral proptosis, tortuous retinal vessels, and intraretinal hemorrhages in all 4 quadrants in the left eye. MRI demonstrated a primarily intraconal, multiloculated, T2-hyperintense mass consistent with a lymphatic malformation...

Trimucrin, a novel small-mass Arg-Gly-Asp (RGD)-containing disintegrin, has been demonstrated to possess anti-platelet and anti-inflammatory effect through blockade of platelet αIIbβ3 and phagocyte αvβ3 integrin. In this study, we found that the platelet-rich plasma prepared from trimucrin-treated rats platelet aggregation was diminished in response to adenosine diphosphate (ADP). We tried to determine whether trimucrin is cardioprotective in rats subjected to myocardial ischemia-reperfusion (I-R) injury...

Extracellular matrix (ECM) is a fundamental component of multicellular organisms. Alteration of its structure and/or molecular composition are associated with several pathologies, among the others with atherosclerosis. To determine how the overall ECM architecture of a tissue as complex as the atheroma may change under varying pathological conditions constitutes a great technical challenge. This entails removing cell components and solubilisation of fibrillar proteins in order to allow enzymatic digestion and mass spectrometry analyses...

A 55-year-old man presented with difficulty breathing, chest pain, and disturbance of consciousness, and was transferred to our hospital. Initial whole body CT revealed a diffuse subarachnoid hemorrhage(SAH)with severe pulmonary edema that was considered neurogenic in origin. He received controlled ventilation under sedation and conservative care for the SAH. One day after the onset of the SAH, his left pupil suddenly became dilated to 6mm, with no reaction to light. Head CT showed no new bleeding. Subsequent CT angiogram revealed a right internal carotid-posterior communicating artery aneurysm(IC-PC AN)with a posterior-lateral projection; however, no vessel abnormality was observed in the left anterior or posterior circulations...
