Ultrastructure Organization of Human Trabeculae Assessed by 3D sSAXS and Relation to Bone Microarchitecture. [PDF]

PLoS ONE, 2016
Although the organization of bone ultrastructure, i.e. the orientation and arrangement of the mineralized collagen fibrils, has been in the focus of research for many years for cortical bone, and many models on the osteonal arrangement have been proposed,

Lamina Cell Shape and Cell Wall Thickness Are Useful Indicators for Metal Tolerance—An Example in Bryophytes

Plants, 2021
Bryophytes are widely used to monitor air quality. Due to the lack of a cuticle, their cells can be compared to the roots of crop plants. This study aimed to test a hypothetical relation between metal tolerance and cell shape in biomonitoring mosses ...

Oxidative stress mediated by gyrophoric acid from the lichen Umbilicaria hirsuta affected apoptosis and stress/survival pathways in HeLa cells

BMC Complementary and Alternative Medicine, 2019
Background Lichens produce a huge diversity of bioactive compounds with several biological effects. Gyrophoric acid (GA) is found in high concentrations in the common lichen Umbilicaria hirsuta, however evidence for biological activity was limited to ...

Diethylcarbamazine Reduces Chronic Inflammation and Fibrosis in Carbon Tetrachloride- (CCl4-) Induced Liver Injury in Mice

Mediators of Inflammation, 2014
This study investigated the anti-inflammatory effects of DEC on the CCl4-induced hepatotoxicity in C57BL/6 mice. Chronic inflammation was induced by i.p. administration of CCl4 0.5 μL/g of body weight through two injections a week for 6 weeks. DEC (50 mg/

Inner ear tissue preservation by rapid freezing: Improving fixation by high-pressure freezing and hybrid methods. [PDF]

, 2014
In the preservation of tissues in as 'close to life' state as possible, rapid freeze fixation has many benefits over conventional chemical fixation. One technique by which rapid freeze-fixation can be achieved, high pressure freezing (HPF), has been ...

Elastin calcification during the initial stage of vascular calcification in kl/kl mice is suppressed by the calcimimetic upacicalcet

Scientific Reports
We performed ultrastructural analyses of the aortae of klotho-deficient (kl/kl) mice to characterize the early stages of medial calcification and to evaluate the inhibitory effects of the calcimimetic upacicalcet.
