INTRODUCTION: Few, if any, radiotracers are available for the in vivo imaging of reactive oxygen species (ROS) in the central nervous system. ROS play a critical role in normal cell processes such as signaling and homeostasis but overproduction of ROS is implicated in several disorders. We describe here the radiosynthesis and initial ex vivo and in vivo evaluation of [(11)C]hydromethidine ([(11)C]HM) as a radiotracer to image ROS using positron emission tomography (PET). METHODS: [(11)C]HM and its deuterated isotopologue [(11)C](4) were produced using [(11)C]methyl triflate in a one-pot, two-step reaction and purified by high performance liquid chromatography...

OBJECTIVE: Needle-related procedures are the most common sources of pain for children in the hospital setting. The most used topical anesthetic, eutectic mixture of local anesthetic (EMLA) cream, may cause transient vasoconstriction. It has been postulated that this vasoconstriction may decrease vein visualization. The application of heat gel pack after removal of EMLA cream in the site of venipuncture counteracts the vasoconstriction, improving vein visualization. We assessed using a prospective randomized controlled trial whether the application of heat gel pack increases the needle procedure success rate...

PURPOSE OF REVIEW: Catheter-directed therapy in deep vein thrombosis (DVT) is a beneficial adjunct treatment when anticoagulation alone does not provide an adequate therapeutic response. This review aims to deliver an up-to-date discussion behind the rationale, safety profile, and clinical outcomes in endovascular management of DVT. RECENT FINDINGS: Early studies have shown that the use of catheter-directed thrombolysis (CDT) to be successful in rapid thrombus removal, carry a lower incidence of postthrombotic syndrome (PTS), and improved quality of life...

Pancreatic allograft thrombosis (PAT) remains the leading cause of non-immunological graft failure. Herein we propose a new CT grading system of PAT to identify risk factors for allograft loss and outline a management algorithm by retrospective review of consecutive pancreatic transplants between 2009-2014. Triple-phase CT scans were graded independently by two radiologists as; Grade 0 - no thrombosis, Grade 1 - peripheral thrombosis, Grade 2 - intermediate non-occlusive thrombosis and Grade 3 - central occlusive thrombosis...

Iridium (Ir) holds great promise for ethanol oxidation reaction (EOR), while its practical applications suffer from the limited shape-controlled synthesis due to its low-energy barrier for nucleation. To overcome this limitation, the preparation of a new class of ultrathin vein-like Ir-tin nanowires (IrSn NWs) with abundant oxidized Sn is reported. By tuning the ratio of Ir to Sn, the optimized Ir67 Sn33 /C exhibits the highest mass density of 95.6 mA mg(-1) Ir for EOR at low potential (0.04 V), which is 4...

Interventional treatment of venous insufficiency has been revolutionized by endovascular techniques. Some of these techniques, and particularly thermal ablation (endovenous laser, radiofrequency) are now recommended as first-line therapy in the latest international guidelines. This is because of less post-operative pain, a shorter leave from employment and similar or lower recurrence rate. Endovenous techniques allow safer and more efficient treatment of certain particular conditions : small saphenous vein, ulcers, and recurrent varicose veins...

Jugular catheterization is a common procedure used under experimental conditions. However, there is considerable variation in the reported techniques, particularly for grower pigs (>40 kg and <60 kg) when larger volumes of blood per sample (>10 mL) are required. This paper provides a complete methodology including the use of current equipment and anaesthetic regimen for grower pigs. This surgical jugular catheterization method was carried out in 30 large white grower pigs. Firstly, the pigs were habituated to human handling for at least two weeks prior to surgery...

Paroxysmal nocturnal haemoglobinuria is a non-malignant stem cell disorder due to acquired somatic mutations in cell surface anchored proteins CD55 and CD59. Both have a compliment inhibitory role and their deficiency leads to intravascular haemolysis. This paper reports a challenging case of a 25 years old male who presented with generalized weakness, exertional dyspnoea and episodic early morning haematuria. Recently, he started developing progressive abdominal distention and dull generalized abdominal pain...

BACKGROUND: Minimally invasive surgery has been validated to be a new standard in living donor hepatectomy for adult-to-pediatric transplantation with less morbidity [1]. Laparoscopic donor hepatectomy can reduce the major concerns about pain and morbidity associated with open surgery and a slow return to daily activities of donors [2]. Herein, we present one case of totally laparoscopic living donor left hepatectomy including the middle hepatic vein (MHV). DONOR AND METHOD: A 37-year-old mother volunteered to donate to her 3-year-old son with biliary atresia (PELD score 7)...

Arterial thrombosis is the main instigating factor of heart attacks and strokes, which result in over 14 million deaths worldwide every year. The mechanism of thrombosis involves factors from the blood and the vessel wall, and it also relies strongly on 3D vessel geometry and local blood flow patterns. Microfluidic chip-based vascular models allow controlled in vitro studies of the interaction between vessel wall and blood in thrombosis, but until now, they could not fully recapitulate the 3D geometry and blood flow patterns of real-life healthy or diseased arteries...

Once incision and drainage of fascial space abscess is performed, irrigation of deep spaces with saline and antibiotic solution should be done daily for effective elimination or reduction of infection. Various advocated aids for irrigation into deeper areas are: small pediatric nasogastric feeding tubes, French catheter, polyethylene irrigation tubes and scalp vein infusion set. All these aids have major inherent disadvantages like, they tend to kink inside the deep spaces limiting the reach of irrigating solution into deeper spaces, are not readily available in dental departments and have to be discarded after every use...

Angiogenesis, new vessel formation from pre-existing vessels, is a highly conserved event through vertebrates. However, the system for tuning angiogenesis by species-intrinsic factors is totally unknown. miR-1224 is a member of mammal-specific mirtrons, which were identified as non-canonical microRNAs. We found that the expression of miR-1224 was upregulated in capillary-like tube-forming human umbilical vein endothelial cells on Matrigel. Enforced expression of miR-1224 stimulated tube formation, whereas repression of endogenous miR-1224 inhibited formation...
