(approximately 600--1000 μmol m s) and O2 uptake in darkness were measured in needles of control, irrigated and irrigated-fertilized trees of Norway spruce (Picea abies (L.) Karst.). Measurements were made at 20 °C and at high CO2 concentrations. The results suggest that, at given times of the year, a major part of the variation in gross photosynthesis of current-year and one-year-old needles a...
OBJECTIVES To determine the effects of intraocular pressure (IOP) and needle diameter on the amount of reflux after intravitreous bevacizumab injection. METHODS Prospective randomized interventional study. Twelve New Zealand white rabbits weighing approximately 2.5 to 3.5 kg each were randomized 1:1 to group 1 or group 2. Bevacizumab stained with trypan blue was used for intravitreous injecti...
OBJECTIVES This study was carried out to determine whether or not pine needles can be used as passive samplers of atmospheric polycyclic aromatic hydrocarbons (PAHs) using the correlation between accumulated PAH concentrations in air (Ca, ng/m(3)) and those deposited on pine needles (Cp, ng/g dry). METHODS PAHs in ambient air was collected using low volume PUF sampler and pine needles was gat...
INTEGRATION OF Ag2Ga NANONEEDLES ON BATCH FABRICATED MICRO-GRIPPERS FOR MATERIAL PROPERTY MEASUREMENT PengXu March 22, 2011 In this thesis self-assembled growth of Ag2Ga nano-needles on batch fabricated micro-grippers are reported. The room temperature growth of Ag2Ga nano-needles have been recently developed as stylus for Atomic Force Microscopy (AFM). Integration of such nano-needles onto bat...
Results From October 2014 to January 2015, we included 28 participants. Fifteen (54%) were female, average age was 67 (SD 14) yrs. and average BMI was 30 kg/m2 (SD 8). Household monthly income was less than R$ 1.000 (US$ 317) for 68% of the participants. Median time of insulin therapy was 10 yrs. (range 6 to 20 yrs.); 23 (74%) selfadministered insulin injections. Twenty-seven (96%) participants...
Purified populations of human monocytes (greater than 99% monocytic) contain a subpopulation of cells (8-20%) that will surround themselves with a radial array of needles within 15 s after exposure to plasma. The needles are composed of fibrin as demonstrated by gel electrophoresis of isolated needles and by their reaction with a monoclonal antibody, UC45, that is specific for the alpha chain o...
Unselected, disposable acupuncture needles from various manufacturers and retail suppliers were taken from a pool of donated and bought samples. Three needles of each type were prepared for electron-microscopy. The needle tips were inspected at two magnifications (x39.37 and x612.5): 52 electron-micrographs were taken of 31 individual needles from 11 different types. No needle-tip looked perfec...
For routine EUS-guided sampling of solid masses and lymph nodes (LNs) ESGE recommends 25G or 22G needles (high quality evidence, strong recommendation); fine needle aspiration (FNA) and fine needle biopsy (FNB) needles are equally recommended (high quality evidence, strong recommendation).When the primary aim of sampling is to obtain a core tissue specimen, ESGE suggests using 19G FNA or FNB ne...
