Fibrotic and inflammatory characteristics of epidural fat adjacent to the ossification area in patients with ossification of the ligament flavum

open access: yesJOR SPINE, Volume 5, Issue 4, December 2022., 2022
We observed the histological and inflammatory characteristics of epidural fat (EF) adjacent to the ossification area in patients with ossification of the thoracic ligament flavum (TOLF) and provide a preliminary basis for investigating the impact of EF on OLF. Morphologically, EF exhibits no significant differences between the TOLF and non‐TOLF groups,

A New Aerosol‐Based Photobioreactor for the Cultivation of Cyanobacteria on Luffa

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Cyanobacteria are promising organisms for sustainable biotechnology due to their ability to grow photoautotrophically and their wide range of products. Many cyanobacteria grow in the form of biofilms, which is why the development of photobioreactors (PBR) for the cultivation of cyanobacteria in the form of biofilms is of great interest ...
