Modifications of proteoglycans, subendothelial retention of low-density lipoproteins (LDL) and their subsequent oxidation initiate the development of atherosclerosis. Therefore, detection of lipoprotein entrapment in the arterial wall is an important feature for the analysis of the mechanisms of atherosclerosis. The administration of fluorescent-labeled LDL in vivo is a breakthrough way to asse...

OBJECTIVE Reconstructive surgery for pelvic organ prolapse is plagued with high failure rates possibly due to impaired healing or regeneration of the vaginal wall. Here, we tested the hypothesis that postoperative administration of local estrogen, direct injection of mesenchymal stem cells (MSCs), or both lead to improved wound healing of the injured vagina in a menopausal rat model. METHODS ...

BACKGROUND Real-time myocardial contrast echocardiography permits the detection of myocardial perfusion abnormalities during stress echocardiography, which may improve the accuracy of the test in detecting coronary artery stenoses. We hypothesized that this technique could be used after a bolus injection of the selective A2A receptor agonist regadenoson to rapidly and safely detect coronary art...

purpose: to evaluate the effect of botulinum toxin-a as an alternate to surgery in acute complete sixth nerve palsy and to shorten the recovery period. methods: thirty patients with acute complete sixth nerve palsy received 1-10 units of botulinum toxin-a (dysport) injection in the medial rectus muscle within one month from the onset of palsy. toxin was injected directly into the muscle belly u...

the aim of this study was to investigate the effects of in ovo injections of albumin, ami-no acid and dextrose into the amnion on the hatchability, growth performance and slaughter yield of ross 308 broiler chicks. fertile eggs (n=360) were assigned to 6 treatment groups (4 replicates of 15 eggs each) including: non-injected eggs (control), and eggs injected with 0.7 ml distilled water (sham), ...

UNLABELLED We prospectively investigated the ideal imaging time to measure vascular uptake after injection of (18)F-FDG. METHODS A total of 17 patients with atherosclerotic abdominal aortic aneurysm underwent dynamic abdominal PET/CT using 2-min frames between 45 and 53, 57 and 65, 115 and 123, and 175 and 183 min after injection of (18)F-FDG. For each period of dynamic imaging, vessel wall a...

Introduction: Myocardial perfusion imaging (MPI) is an important imaging modality in managing patients with cardiovascular disease. MPI has a significant role in diagnosis and management of cardiovascular disease; however it is subjected to different artifacts. Combining pharmacologic stress with submaximal exercise reduces side effects, improves image quality, and enhances the...

â  the ampulla of vater is commonly located in the posteromeâ­dial wall of the second portion of the duodenum. at times, the ampulla of vater may be found at uncommon sites such as the third and fourth portions of the duodenum, the duodenal bulb and the stomach. we found the ampulla of vater in the pyloric channel in a 44 year old patient who had undergone surgery for acute cholecystitis. an in...

The aim of this paper is to clarify some physical-mechanical aspects involved in the carbon dioxide angiography procedure (CO₂ angiography), with a particular attention to a possible damage of the vascular wall. CO₂ angiography is widely used on patients with iodine intolerance. The injection of a gaseous element, in most cases manually performed, requires a long training period. Automatic syst...
