The attenuation of doxorubicin-induced testicular toxicity with improved testicular histoarchitecture of mice by the bioactive compounds in Solanum anomalum leaves: Experimental and computational studies [PDF]

open access: yesToxicology Reports
Doxorubicin, as an antibiotic causes toxicity in human tissues through the generation of oxidant species; however, Solanum anomalum (Solanaceae) is ethnopharmacologically and scientifically reported to possess antidotal activities.

Solvent effect on the morphology of the bee: structure observed by atomic force microscopy on bitumen sample [PDF]

open access: yesMaterials Research, 2014
The objective of this work was to characterize the asphaltic cement penetration grade 30/45 (CAP 30/45) based on the morphology of nanostructures called "bee" structure observed and its modification when the binder was diluted in heptanes or toluene. The

Über 1-Aza-bicyclo-heptane

open access: yesCHIMIA, 1976
A simple way to synthesize 7-phenyl-1-aza-bicyclo[2,2,1]heptanes out of 4-benzoyl-pyridines is described. The corresponding 3- benzoyl-pyridines did not yield the expected 7-phenyl-1-azabicyclo [3,1,1] heptanes.
