Frap
Definition:
(v. t.) To draw together; to bind with a view to secure and strengthen, as a vessel by passing cables around it; to tighten; as a tackle by drawing the lines together.
(v. t.) To brace by drawing together, as the cords of a drum.
Example Sentences:
(1) Single cells in pairs or clusters of touching cells in each exposure group were examined with FRAP.
(2) Analysis of lumbar sensory ganglia revealed that small type-B neurons immunoreactive for adenosine deaminase were also immunoreactive for somatostatin but not substance P. In addition, adenosine deaminase-positive neurons lacked histochemical reaction-product for FRAP and exhibited the lowest activity of 5'-nucleotidase.

(5) Peripheral nerve section or local capsaicin application produces depletion of substance P and an enzymatic marker, fluoride-resistant acid phosphatase (FRAP), from circumscribed regions of the terminal areas in the spinal cord.
(6) In addition, the presence of fluoride resistant acid phosphatase (FRAP)-enzyme activity (-EA) in retrogradely Fast blue-labeled saphenous and gastrocnemius nerves was investigated by subsequent enzyme cytochemical analysis.
(7) By fluorescence recovery after photobleaching (FRAP), we obtained the mean diffusion coefficients in a dilute, aqueous reference phase (Do), the mean diffusion coefficients in the model matrices (D), and the mean hydrodynamic radii (RH) for selected tracer fractions.
(8) It appears that the lack of coexistence of adenosine deaminase with either FRAP or 5'-nucleotidase cannot be attributed simply to a coexistence of the two latter enzymes since some 5'-nucleotidase-positive neurons lacking FRAP were also devoid of adenosine deaminase-immunoreactivity.
(9) After complete transection of the brachial plexus, partial depletion of FRAP was seen in the lower cervical and upper thoracic cord; the degree of FRAP disappearance was striking in segments C5, C6 and C7, and slight between segments C5 and C6.
(10) These studies illustrate significant lectin-reactive cell surface carbohydrate expression by non-peptidergic, FRAP(+) sensory ganglion cells in the rat, and provide a means for visualizing the extensive, non-peptidergic, small sensory ganglion cell subpopulations, probably including a substantial proportion of nociceptive and unmyelinated peripheral axons.
(11) Alternative interpretations of the expression of acid phosphatase activity in a select class of small sensory ganglion cells are suggested, including several possible non-synaptic roles of FRAP in the peripheral nervous system.

(18) One week after axotomy of the sural nerve, FRAP is depleted from its terminals and a gap appears in the normal FRAP staining pattern in the lumbar enlargement of the spinal cord.
(19) The SP-LI, ENK-LI and FRAP were all weakened in dorsal horn of spinal cord 1h after capsaicin treatment.
(20) Various histochemical markers that colocalize with FRAP in dorsal root ganglion (DRG) and spinal cord were examined, and a plant lectin, Griffonia simplicifolia I-B4, has been identified that not only selectively labels FRAP(+) sensory ganglion cells and central terminals in spinal cord, but also differentially stains a large number of thin axons in testicular and corneal whole mounts.
