Distribution of pancreatic B cell imaging agent (99m)Tc-DTPA-NGN2 in the body and animal experimental research on pancreatic B cell functional imaging.
Article in American journal of translational research, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo explore the feasibility of the application of (99m)Tc-DTPA-Nateglinide as a nuclear medicine imaging agent for evaluating pancreatic B cell function.
methods(1) Distribution of the experiment: Forty-two mice were selected and divided into seven groups. Each mice was injected with 3.7 MBq (100 μCi) of (99m)Tc-DTPA-NGN2 from the vena caudalis and was sacrificed by bloodletting at five minutes, 15 minutes, 30 minutes, one hour, two hours, four hours and six hours, respectively. Then, their tissues and organs such as the heart, liver, spleen, brain, kidneys, bones, small bowels, stomach and pancreas,and blood were collected, weighted, and their radioactivity was tested. Subsequently, the percentage injection dose rate (%ID/g) per gram of tissue was calculated. (2) Imaging experiment: Thirty-five mice were selected and divided into seven groups. Each was injected with 18.5 MBq (100 μCi) of (99m)Tc-DTPA-NGN2 from the vena caudalis and imaging were conducted at the same time as above. (3) Forty-eight Wistar rats were attained and randomly divided into four groups. The first group served as the healthy control group, while the second, third and fourth groups were diabetic model groups induced by intraperitoneally injecting STZ at different doses. Each group was injected with (99m)Tc-DTPA-Nateglinide from the vena caudalis, and radiological evaluations were conducted at 30 minutes, one hour, 1.5 hours and two hours, respectively. The data obtained were estimated using a correlation comparison with the levels of insulin and immunohistochemical count of beta cells.
resultsThe (99m)Tc-DTPA-Nateglinide demonstrated good imaging in the pancreases of mice and rats, and was positively correlated to the level of insulin and the number of pancreatic beta cells.
conclusionPancreatic beta cell imaging using (99m)Tc-DTPA-Nateglinide may be a method to evaluate pancreatic beta cell function.
