Abstract:
Ectopic calcification can cause pain and limit mobility. Studies suggest that circadian genes may play a role in the calcification process. Core circadian genes Clock, Npas2, and Bmal1 are transcription factors that form CLOCK:BMAL1 or NPAS2:BMAL1 transactivator complexes that drive the rhythmic expression of circadian oscillator genes and output genes. Circadian oscillator genes Period1-3 and Cryptochrome1-2 encode proteins that form transcription repressor complexes that feedback to inhibit CLOCK/NPAS2:BMAL1 activity, thus completing the feedback loop that is the basis of the molecular circa

Background: Cardiovascular disease is the leading cause of mortality in patients with Chronic Kidney Disease (CKD). Vascular calcification is a significant contributor to cardiovascular mortality in CKD. Klotho is a 130kDa transmembrane protein with cardiovasculo-protective properties and also functions as a co-factor for the phosphatonin, fibroblast growth factor (FGF)-23 at the kidney. FGF-23 levels rise in CKD despite progression of accelerated vascular calcification (VC). There are currently conflicting data on whether FGF-23 may exhibit direct vasculo-protective effects in CKD.

Anthropogenic carbon dioxide (CO2) emissions are increasing the atmospheric CO2 concentration and the oceans are absorbing around 1/3 them. The CO2 hydrolysis increases the H+ concentration, decreasing the pH, while the proportions of the HCO3- and CO32- ions are also affected. This process already led to a decrease of 0.1 pH units in surface seawater. According to "business-as-usual" models, provided by the Intergovernmental Panel on Climate Change (IPCC), the pH is expected to decrease 0.3-0.5 units by 2100 and 0.7-0.8 by 2300.
