Evaluation of mortality and 17 physical endpoints at 120 hpf. Zebrafish embryos were exposed to six concentrations of TCDD (0, 0.0625, 0.125, 0.25, 0.5, 1.0ng/mL) at the shield stage as described in the "Waterborne Exposure" section of the "Methods." The animals were loaded into round-bottom 96-well plates, with one embryo in 100 [micro]L embryo media per well.
The first 5-HT-IR neuron appeared in the blastula stage (16 hpf).
When compared with other Saccostrea species, the timing of developmental stages during embryogenesis varies, although development to the D-stage for the four species is completed within 16-24 hpf (Table 1).
However, recurrence has been reported in a smooth muscle tumor of somatic deep soft tissue with a mitotic activity of 1 mitosis per 50 HPF .
Eosinophils were counted according to a standardized protocol, and results were normalized for the HPF areas of the microscopes used.
Mortalities were primarily observed at the earliest observation following 8 h of exposure (11 hpf) and mortality did not increase substantially post exposure to 35 hpf.
Malignant PT is characterized by marked stromal cellularity and nuclear pleomorphism, stromal overgrowth, and more than 10 mitoses per 10 HPF (Figure, E).
Figure 11 shows comparison of HPF and LPF in detection of tumor using watershed.
HPF is nationally known for our trusted and effective programs that put families on the path to sustainable homeownership and financial empowerment.
Compared with the control group, the exposure of the embryos to the Ag nanospheres or Ag nanoplates significantly increased the mortality of the embryos at both the 24 hours post fertilization (24 hpf) stage and the 48 hours post fertilization (48 hpf) stage.
Microscopic hematuria is defined as 3 red blood cells (RBC)/high power field (HPF) on microscopic examination of the centrifuged urine specimen, in 2 of 3 freshly voided, clean catch, mid-stream urine samples.[sup.1]
Blood vessels in the fibrous tissue capsule were quantified by counting numbers of vessels per high power field (HPF) with the assistance of the digital analysis software using a semi-automated method [3, 5].
