Sequestration, a condition where a section of bone becomes necrotic due to a loss of vascularity or thrombosis, can be a challenging complication of osteomyelitis. This review explores the pathophysiology of sequestration, highlighting the role of the periosteum in forming involucrum and creeping substitution which facilitate revascularization and bone formation. The authors also discuss the induced membrane technique, a two-stage surgical procedure for cases of failed healing of sequestration. Future directions include the potential use of prophylactic anticoagulation and novel drugs targeting immunocoagulopathy, as well as the development of advanced imaging techniques and single-stage surgical procedures.

Background: Mammalian metallothioneins (MTs) play a crucial role in maintaining Zn(II) and Cu(I) homeostasis, as well as regulating the cellular redox potential. They are involved in cancer resistance to cisplatin-related drugs and the sequestration of toxic metal ions. To investigate their participation in specific physiological and pathological processes, it is imperative to develop an analytical method for measuring changes in protein concentration both in vitro and in vivo.

The cost effectiveness of mitigating climate change through afforestation needs to be evaluated for regions with a fragile environment and vulnerable ecosystems. This study develops an integrated geographic-economic-ecological framework to evaluate the cost-effectiveness of afforestation for carbon sequestration in Northwest China. It employs a spatial model of natural factors and a bioeconomic optimization model to identify marginal lands suitable for afforestation.

Terrestrial ecosystem carbon sinks are a natural deposit that absorbs carbon from the atmosphere. A stable land carbon sink facilitates more reliable predictions of carbon sequestration under changing climate conditions. In contrast, a highly variable land carbon sink will introduce significant uncertainty into model predictions.

The addition of exogenous organic carbon (C) to soil can either accelerate or retard the soil organic carbon (SOC) mineralization, i.e., the priming effect (PE), which plays a crucial role in SOC sequestration and thus is significant in the context of global warming.

Mitochondrial activity is necessary for the maintenance of many liver functions. In particular, mitochondrial fatty acid oxidation (FAO) is required for energy production and lipid homeostasis. This key metabolic pathway is finely tuned by the mitochondrial respiratory chain (MRC) activity and different transcription factors such as peroxisome proliferator-activated receptor α (PPARα).
