Pulse-modulated follow-up in a separate institutional programme
The reported finding
Original abstract: male whole-brain Evans-blue content rose from 0.08±0.01 mg% control to 0.13±0.03 at 900 MHz and 0.26±0.05 at 1800 MHz (both p<0.01). Female response reported at 900 MHz, but not 1800 MHz. The abstract does not define the ± measure.
Reading it carefully
Original abstract only; not an independent programme from RF-030 or replication of dark-neuron pathology. Absorbed-dose details remain unverified.
Inside the study
Exposure conditions
Pulse-modulated 900 and 1800 MHz, 20 min. Absorbed dose, pulse parameters and temperature measurement not verified; no low-dose or nonthermal claim adopted.
Design & controls
Six groups of young adult male/female Wistar albino rats; injected Evans-blue, quantitative whole-brain assay; group n/masking to verify.
Related research & shared cohorts
Gazi University programme; journal year 2016, online year 2015.
The protection question raised
Do frequency, pulse format and sex modify barrier responses? Unverified absorbed-dose and temperature details prevent this abstract-level record from establishing the adequacy of an exposure limit.
