IRF2BP2 Deficiency: An Important Form of Common Variable Immunodeficiency with ...
Udemgba, Chioma; Pillay, Bethany; Shafer, Samantha; Alberstadt, Angelika; Abers, Michael; Gilliaux, Olivier; Chen, Karin; Rae, William; Hanitsch, LeifBackground: IRF2BP2 is a transcription factor that plays an important role in regulating immune pathways, angiogenesis, apoptosis, and cell differentiation. Defects in this gene have been implicated in immunodeficiency. Objectives: To deepen the understanding of the clinical implications of IRF2BP2 variants, we sought to clinically characterize and functionally test 34 individuals with IRF2BP2 variants. Methods...

Height-diameter allometry of tropical forest trees
Feldpausch, Ted R.; Banin, Lindsay F.; Phillips, Oliver L.; Baker, Timothy R.; Lewis, Simon L.; Quesada, Carlos Alberto; Affum-Baffoe, KofiTropical tree height-diameter (<i>H:D</i>) relationships may vary by forest type and region making large-scale estimates of above-ground biomass subject to bias if they ignore these differences in stem allometry. We have therefore developed a new global tropical forest database consisting of 39 955 concurrent <i>H</i> and <i>D</i> measurements encompassing 283 sites in 22 tropical countries. Utilising this data...
Structural dynamics of tropical moist forest gaps
Hunter, Maria O.; Keller, Michael; Morton, Douglas C.; Cook, Bruce Douglas; Lefsky, Michael Andrew; Ducey, Mark J.; Saleska, Scott ReidGap phase dynamics are the dominant mode of forest turnover in tropical forests. However, gap processes are infrequently studied at the landscape scale. Airborne lidar data offer detailed information on three-dimensional forest structure, providing a means to characterize fine-scale (1 m) processes in tropical forests over large areas. Lidar-based estimates of forest structure (top down) differ from traditional...
Estimation of biomass and carbon stocks: The case of the Atlantic Forest
Vieira, Simone Aparecida; Alves, Luciana Ferreira; Aidar, Marcos Pereira Marinho; Araújo, Luciana Spinelli; Baker, Timothy R.The main objective of this paper is to present and discuss the best methods to estimate live above ground biomass in the Atlantic Forest. The methods presented and conclusions are the products of a workshop entitled "Estimation of Biomass and Carbon Stocks: the Case of Atlantic Rain Forest". Aboveground biomass (AGB) in tropical forests is mainly contained in trees. Tree biomass is a function of wood volume, ob...
