METHODS: Sequential staining and high resolution imaging were used to study freshly prepared cryo-sections from 10 patients with histologically confirmed steatohepatitis using oil red O for fat droplet identification, H&E to identify ballooning, and anti-K18 to confirm cytoskeletal changes.ONCLUSIONS: These results indicate a relationship between cellular ballooning, fat droplet accumulation, and cytoskeletal injury in NASH. We speculate that injury to multiple, organelles including fat droplets and endoplasmic reticulum, contribute to this characteristic finding.
In Minnesota, the most commonly affected woody plants are roses (Rosa spp. ), willow (Salix spp. ), poplar (Populus spp. ) and fruit trees like apple (Malus spp. ), cherry, plum or apricot (Prunus spp. ). All of these plants are highly susceptible to crown gall.rown gall is caused by the bacterium, Agrobacterium tumefaciens. This pathogen is found on more than 600 different species of plants worldwide including many common vegetables, weeds, deciduous and evergreen trees and shrubs.
Gall wasps produce species-specific and generation-specific galls on several species of oaks. In some species, the adults and galls are similar in the first and third generations, while very different in the second and fourth generations.ackberry trees host several species of gall psyllids. They form 1/8- to 1/4-inch galls on the leaves and petioles. The insects overwinter as adults in bark crevices and other sheltered locations (including home siding and window frames). After mating in the spring, the females lay eggs on the undersides of leaves.
