Background: Discussions about limiting anthropogenic emissions of CO[Formula: see text] often focus on transition to renewable energy sources and on carbon capture and storage (CCS) of CO[Formula: see text]. The potential contributions from forests, forest products and other low-tech strategies are less frequently discussed. Here we develop a new simulation model to assess the global carbon content in forests and apply the model to study active annual carbon harvest 100 years into the future.
Results: The numerical experiments show that under a hypothetical scenario of globally sustainable forestry the world's forests could provide a large carbon sink, about one gigatonne per year, due to enhancement of carbon stock in tree biomass. In addition, a large amount of wood, 11.5 GT of carbon per year, could be extracted for reducing CO[Formula: see text] emissions by substitution of wood for fossil fuels.
Conclusion: The results of this study indicate that carbon harvest from forests and carbon storage in living forests have a significant potential for CCS on a global scale.

Background: Aortoiliac disease (AID) is a variant of peripheral artery disease involving the infrarenal aorta and iliac arteries. Similar to other arterial diseases, aortoiliac disease obstructs blood flow through narrowed lumens or by embolization of plaques. AID, when symptomatic, may present with a triad of claudication, impotence, and absence of femoral pulses, a triad also referred as Leriche Syndrome (LS).

Background: ASD is a relatively rare subset among patients with situs inversus dextrocardia with concordant AV connection and a minimally invasive approach in dextrocardia has yet to be standardized. The present case describes a case surgical closure of ostium secundum ASD by left mini-thoracotomy approach in patient with dextrocardia and situs inversus.
Case Presentation: The present case describes a 44-year female patient of ostium secundum ASD in dextrocardia with situs inversus.

Infective endocarditis carries a high risk of morbidity and mortality with recurrent infections and non-compliance. In the case of right-sided endocarditis, the indications for intervention are less clear. The Angiovac procedure provides a treatment for right-sided endocarditis that is a less-invasive and ideal for a complicated patient population.

Introduction: Arteriovenous (AV) fistula creation is the most common surgical procedure for providing vascular access for haemodialysis in patients with chronic kidney disease (CKD). The functioning of fistula dictates the quality of dialysis and the longevity of patients. The most common circumstances that require surgical takedown of AV fistula are thrombosis and rupture.
