Bronchopulmonary sequestration is a rare congenital malformation of the lower respiratory tract. Its presentation is varied, and it rarely presents in adulthood. We report the case of a 31-year-old woman who was admitted with recurrent pneumonia. She had been treated for pneumonia multiple times within the last 3 years. On subsequent workup, she was found to have intra-lobar bronchopulmonary se...

Elevated carbohydrate antigen (CA) 19-9 can indicate malignancies of the gastrointestinal, pancreatic, and biliary tracts, and be found in a pulmonary sequestration. A 30-year-old man visited Seoul National University Bundang Hospital due to elevated CA 19-9 levels, representing pulmonary sequestration of the bilateral lower lobes, which were connected with each other. We performed left lower l...

This paper reviews the Regional Carbon Sequestration Partnerships (RCSP) concept, which is a first attempt to bring the U.S. Department of Energy's (DOE) carbon sequestration program activities into the "real world" by using a geographically-disposed-system type approach for the U.S. Each regional partnership is unique and covers a unique section of the U.S. and is tasked with determining how t...

evaluation of carbon input is one of the most important factors for estimating soil carbon changes and potential for carbon sequestration. to evaluate the net primary productivity (npp) and soil carbon input in agricultural eco-systems of iran, data for yield, cultivated area, harvest index (hi) and shoot /root ratio in different crops including: wheat, barley, maize, cotton, rice, alfalfa and ...

Giant bamboo Dendrocalamus asper is recommended in environmental and livelihood programs in the Philippines due to its various ecological, economic and social benefits. However, there are limited data on the ecology of giant bamboo litterfall production, which contributes to soil nutrient availability. Bamboo also contributed in carbon sequestration. The study was conducted within the ...

CO2 sequestration may be an avenue to mitigate climate change. CO2 sequestration by mineral carbonation can be achieved by the reaction of CO2 with alkaline silicates. Here, we evaluate how alkaline silicate mineral-based CO2 sequestration can be achieved using environmental biotechnological processes. Several biotechnological processes rely on the sequence of (i) an acid-producing reaction suc...

Sommer and Bossio (2014) model the potential soil organic carbon (SOC) sequestration in agricultural soils (croplands and grasslands) during the next 87 years, concluding that this process cannot be considered as a climate stabilization wedge. We argue, however, that the amounts of SOC potentially sequestered in both scenarios (pessimistic and optimistic) fulfil the requirements for being consi...

Pulmonary sequestration is a congenital malformation characterized by focal area of dysplastic lung tissue that lacks normal communication with tracheobronchial tree and receives blood supply from systemic arteries. Surgical resection has been the conventional method of treatment of pulmonary sequestration. In recent years transarterial embolization of the anomalous systemic arteries has emerge...

Calcium ions (Ca(2+)) are indispensable for the physiology of organisms and the molecular regulation of cells. We observed that CGK733, a synthetic chemical substance, induced non-apoptotic cell death and stimulated reversible calcium sequestration by vesicles in pancreatic cancer cells. The endoplasmic reticulum (ER) stress eukaryotic translation initiation factor 2-alpha kinase 3/C/EBP homolo...
