- چکیده:
- چکیده انگلیسی: Summer maize (Zea mays L.) is one of the dominant crops in the North China Plain (NCP). Its growth is greatly influenced by the spatial-temporal variation of climatic variables, especially solar radiation, temperature and rainfall. The WOFOST (version 7.1) model was applied to evaluate the impact of climatic variability on summer maize yields using historical meteorological data from 1961 to 2000. The model was calibrated and validated using data from field experiments conducted during the period 1998-1999 and simulations were run to analyses the climate impact. Simulated potential yield ranges from 7.7 to 10.0 Mg ha-1, with an increasing trend from south to north, while rainfed yield ranges from 4.3 to 8.1 Mg ha-1, and with an increasing trend from the middle to the north and south of NCP. Gaps between potential and rainfed yields also decreased from the middle to the north and south. The pattern of potential yield was mainly attributed to the distribution of solar radiation and temperature, whereas rainfed yield was mainly influenced by the distribution of rainfall. Interannual variability n of potential yield is small, and was closely related to the variation of solar radiation, while rainfed yield varied greatly, especially in the middle of the plain, where the rainfall is lowest. Combined with consistent research results of winter wheat, results of this study offer scientific basis for policy makers and researchers concerned with the management of food marketing decisions and water resource reallocation.

- چکیده:
- چکیده انگلیسی: Background: Neuroendocrine tumors (NETs) are rare tumors that can originate from any part of the body. Often,
imaging or exploratory surgery can assist in the identification of the tumor primary site, which is critical to the
management of the disease. Neuroendocrine tumors (NETs) of unknown primary constitute approximately 10-15%
of all NETs. Determining the original site of the tumor is critical to providing appropriate and effective treatment.
Methods: We performed a retrospective review of neuroendocrine tumors at our institution between 2012 and 2016
using a 92-gene cancer ID analysis. Results: 56 patients with NETs of unknown primary were identified. Samples
for 38 of the 56 underwent the 92-gene cancer ID analysis. The primary site of the tumor was identified with >95%
certainty in 35 of the 38 patients. Conclusion: The 92-gene cancer ID analysis identified a primary site in 92% of our
NETs study cohort that previously had been unknown. The results have direct implications on management of patients
with regard to FDA-approved treatment options.- انتشار مقاله: 29-01-1397
