Introduction: Although the global incidence of non-cardia gastric cancer (NCGC) is decreasing, there are limited data on sex-specific incidence in the United States. This study aimed to investigate time trends of NCGC from the SEER database to externally validate findings in a SEER-independent national database, and to further assess trends among subpopulations.
Methods: Age-adjusted incidence rates of NCGC were obtained from the SEER database from 2000 to 2018.

Although similar patterns of phenotypic diversification are often observed in phylogenetically independent lineages, differences in the magnitude and direction of phenotypic divergence have been also observed among independent lineages, even when exposed to the same ecological gradients. The stickleback family is a good model with which to explore the ecological and genetic basis of parallel and nonparallel patterns of phenotypic evolution, because there are a variety of populations and species that are locally adapted to divergent environments. Although the patterns of phenotypic divergence as well as the genetic and ecological mechanisms have been well characterized in threespine sticklebacks, Gasterosteus aculeatus, we know little about the patterns of phenotypic diversification in other stickleback lineages.

Parallel phenotypic evolution in similar environments has been well studied in evolutionary biology; however, comparatively little is known about the influence of determinism and historical contingency on the nature, extent and generality of this divergence. Taking advantage of a novel system containing multiple lake-stream stickleback populations, we examined the extent of ecological, morphological and genetic divergence between three-spined stickleback present in parapatric environments. Consistent with other lake-stream studies, we found a shift towards a deeper body and shorter gill rakers in stream fish.

To determine the influence of incubation time, diet, and particle size on Ca and P solubility in vitro, experimental diets were formulated to contain 0.89% Ca and 0.40% available P (positive control; PC) or 0.

Three young ostriches (Struthio camelus), aged 4 months, were found to have zygomycotic proventriculitis and ventriculitis associated with impaction. Clinical signs were anorexia, chronic weight loss, weakness and lethargy followed by scant faeces for seven days. Proventriculi and ventriculi from birds were full of masses of hay, grass, leaves and other fibrous materials in combination with sand, gravel and plastic.
