Brain stem metastases treated with radiosurgery: prognostic factors of survival and life expectancy estimation
(ELSEVIER SCIENCE INC, 2009)
Background: The objective of this study is to study prognostic factors of survival and 3 stratification systems for life expectancy estimation in patients with brain stem metastases treated with radiosurgery.
Nitrogen and radiation effects during the active spike-growth phase on floret development and biomass partitioning in 2- and 6-rowed barley isolines
(Csiro Publishing, 2010-10)
The paramount importance of accumulated biomass in active-growing spikes over the number of grains per unit area has been well documented. However, it is not clear how different nitrogen (N) and radiation supplies during ...
Growth and biomass partitioning of nine provenances of Quillaja saponaria seedlings to water stress
(NISC Pty Ltd, 2019)
© 2018, © 2018 NISC (Pty) Ltd.Information on the morphological and physiological responses of seedlings to stressors, such as water stress, is required for successful early establishment of seedlings. We examined provenance ...
Differences in larval nutritional requirements and female oviposition preference reflect the order of fruit colonization of Zaprionus indianus and Drosophila simulans
(Elsevier B. V., 2015)
Species coexist using the same nutritional resource by partitioning it either in space or time, but few studies explore how species-specific nutritional requirements allow partitioning. Zaprionus indianus and Drosophila ...
Bayesian regularization for flexible baseline hazard functions in Cox survival models
(WILEY, 2021)
Fully Bayesian methods for Cox models specify a model for the baseline hazard function. Parametric approaches generally provide monotone estimations. Semi-parametric choices allow for more flexible patterns but they can ...
Overall survival in patients with resected glioblastoma treated with adjuvant therapy: a retrospective study in a public hospital in Chile
(Cureus, 2021)
Glioblastoma (GB) is the most frequent and aggressive primary tumor of the central nervous system (CNS) in adults. Standard treatment is complete tumor resection followed by concomitant radiochemotherapy (RCT) and subsequent ...
Insight on ALPPS - Associating Liver Partition and Portal Vein Ligation for Staged Hepatectomy - mechanisms: activation of mTOR pathway
(Elsevier, 2018-08)
Background: ALPPS procedure has been introduced to increase the volume of future liver remnant. The mechanisms underlying the accelerated regeneration observed with ALPPS are unknown. It was hypothesized that AMPK/mTOR is ...
Partitioning the relative contribution of one-phase and two-phase seed dispersal when evaluating seed dispersal effectiveness
(Wiley-Blackwell, 2015-02-01)
Seed dispersal effectiveness (SDE) is a conceptual framework that aims at quantifying the contribution of seed dispersal vectors to plant fitness. While it is well recognized that diplochorous dispersal systems, characterized ...
