Salt marshes worldwide are faced with threats from rising sea levels and coastal development. We measured changes in salt marsh vegetation structure using remote sensing and its consequences for carbon sequestration, wave attenuation, and sediment trapping ability using remotely sensed imaging, field measurement data, and the published literature data pertaining to the Yangtze Estuary, a rapidl...
The Society for Assisted Reproductive Technology (SART) method of embryo grading is unique, simple, and widely practiced, and its use has been mandatory for SART membership programs since 2010. Developed by SART in 2006, the current embryo grading system categories, “good, fair, and poor,” are limited because they do not describe the best 1-2 embryos in the interest of keeping pace with the shi...
The rebuttal of Oberhuber’s sub-division of Marsh III type in celiac disease (1) and its subsequent correspondence in the past and present issues of GHFBB allow us to review the current thinking on the histopathological classification of celiac disease. In the Definition of Medicine, Avicenna argues: -“While some divide medicine into a theoretical and a practical [applied] science, others may a...
Salt marsh ecosystems have been considered not susceptible to nitrogen overloading because early studies suggested that salt marshes adsorbed excess nutrients in plant growth. However, the possible effect of nutrient loading on species composition, and the combined effects of nutrients and altered species composition on structure and function, was largely ignored. Failure to understand interact...
Here we report N(2)O emission results for freshwater marshes isolated from human activities at the Sanjiang Experimental Station of Marsh Wetland Ecology in northeastern China. These results are important for us to understand N(2)O emission in natural processes in undisturbed freshwater marsh. Two adjacent plots of Deyeuxia angustifolia freshwater marsh with different water regimes, i.e., seaso...
introduction: c - reactive protein (crp) is an acute-phase plasma protein that can be used as a marker of activation of the immune system. in response to several inflammatory reactions,the concentration of crp increases and recently have been applicated as a cancer detector in some studies. we aimed to evaluate the relation between crp level and the staging and grading of gastric and colon mali...
Mangroves are species of halophytic intertidal trees and shrubs derived from tropical genera and are likely delimited in latitudinal range by varying sensitivity to cold. There is now sufficient evidence that mangrove species have proliferated at or near their poleward limits on at least five continents over the past half century, at the expense of salt marsh. Avicennia is the most cold-toleran...
The establishment of parasites with complex life cycles is generally thought to be regulated by free-living species richness and the stability of local ecological interactions. In this study, we test the prediction that stable host communities are prerequisite for the establishment of complex multi-host parasite life cycles. The colonization of naïve killifish, Fundulus heteroclitus, by parasit...
There are anecdotal reports that upstream water withdrawals over the past 50 years have altered the salinity structure of coastal Georgia estuaries. Since few consistent salinity records exist, it may be possible to use shifts in vegetation to document salinity change. The purpose of this study was to use aerial photographs and GIS analysis to determine if the location of the brackish water int...
