IVU examines the urinary tract following the introduction of water-soluble non-ionic radio-opaque contrast media. Typically the median cubital vein is punctured with a 19 gauge needle and the warmed (18–20oC)contrast media is injected in one bolus. The contrast medium is excreted by the kidneys, rendering the urine opaque to X-rays and allowing visualisation of the renal parenchyma together with the calyces, renal pelvis, ureters and bladder. Abdominal preparation is normally necessary, but is abandoned if the examination is carried out as an emergency procedure. The examination is normally carried out using conventional over-couch radiography equipment capable of performing tomography. Use of abdominal compression is employed in many centres to delay drainage and promote filling of the renal pelvis/calyceal system.

An 18G access needle for routine IV access or 21G micro-puncture needle can be used to gain initial access in the ante-cubital fossa. The superficial median cubital vein is frequentlypalpable and can be found coursing in the lateral to medialdirection as it drains cranially. Once vessel puncture is madeand blood flow is confirmed, a 0.014-in nitinol wire can beused to insert a micropuncture sheath that allows a 0.035-inwire for exchanging to a larger sheath size (i.e., up to 8-Fr).
The Pericardium (PC)

It occasionally divides into intermediate median cephalic and basilic veins, which drain into their respective veins. The median cubital vein often receives this median vein of the forearm, otherwise known as the median antebrachial vein.

Participants were required to attend the laboratory a total of three times. The first was a screening visit to ensure eligibility, the second and third were study visits. On all study day visits, participants arrived in the laboratory at 8 am and confirmed that they had fasted for 12 h prior and were in good health. An inlaying cannula was then inserted into the participants left median cubital vein by a qualified phlebotomist. Fifteen millilitres of blood were then drawn from the cannula using a 5 ml vacutainer containing EDTA and a 10 ml vacutainer containing LH. Depending upon randomised treatment allocation, the participant then consumed either “Blackadder” juice or the matched control. Drinks were presented to participants chilled in a sealed opaque bottle and they were given 5 min to consume the drink through a straw. A further 15 ml of blood was then removed via the cannula; at; 15, 30, 4560, 100, 120, 150, 180 and 240 min post consumption. Participants were then free to leave. Participants were required to attend a 24 h follow up visit where 15 ml of blood was obtained via venepuncture. Diet was controlled (nil by mouth other than water) during the 4 h period after consumption of the treatments. There was no standardisation of food intake across visits during 4–24 h. Participants were however asked to consume no purple coloured berries. A graphical representation of the study design can be seen in Fig. 1.

Whole human blood was withdrawn via the median cubital vein of volunteers. A 4-ml sample of blood was placed in a heparin-coated anticoagulation tube (Kangjian Medical Apparatus, Jiangsu, China), while 50 ml of blood was mixed with a solution of citrate phosphate dextrose adenine (CPDA-1; Sigma Aldrich, St Louis, MO, USA). All samples were stored at 4 °C. Bovine whole blood was withdrawn via the carotid vein of cattle (Beijing Created Biotechnology, Beijing, China), mixed with CPDA-1, and stored at 4 °C. Next, human haemoglobin (hHb) and bovine haemoglobin (bHb) were purified from whole blood mixed with CPDA-1 by anion-exchange chromatography, as previously described [28–30]. Haemoglobin solutions were prepared at a concentration of 5 g/dL. After filtration through a 0.22-mm polyether sulphone filter, solutions were stored at −80 °C.

Sixteen healthy female and male donors aged between 21 and 40 years participated in this study. Heparinized blood samples were taken from median cubital vein according to a standard clinical procedure. Peripheral blood mononuclear cells (PBMC) were isolated using Ficoll-Paque (Ficoll-Paque™ PREMIUM, 1.077 ± 0.001 g/mL, GE Healthcare, USA) gradient centrifugation. CD14-positive cells were isolated from PBMC by magnetic column separation (MS columns, Miltenyi Biotec, Bergisch Gladbach, Germany) using CD14 MicroBeads (CD14 Micro Beads human, Miltenyi Biotec), according to the manufacturer’s instruction. Purity and viability of isolated CD14-positive cells were assessed by staining with peridinin chlorophyll (PerCP)-labeled anti-CD14 antibody (Ab), (eBioscience, San Diego, CA) and a membrane impermeable dye propidium iodide (PI) (eBioscience).
