Genetic differences in lung adenocarcinoma cells from patients of African and European ancestry
In the past two decades, advancements in cancer genetics research have significantly enhanced our molecular comprehension of human cancers. This progress has led to the development of improved clinical tools for the precise diagnosis, prognosis prediction, and tailored treatment of cancers. …

Characterizing physiological and genetic differences in the early immune response to Haemonchus contortus in resistant and susceptible sheep
… cell type 2 (TH2) response. However, profound differences in TH2 responses were observed in the abomasal mucosa, where hair sheep expressed more IL-4, -13 and -33 than wool sheep. These data thus document the presence of immunological differences between the breeds. Immune responses to larval …

Use of machine learning techniques for SNP based prediction of ancestry
Some have argued that the genetic differences between continentally defined groups are relatively small and unlikely to have biomedical significance. In this study, the extent of variation between continentally defined groups was evaluated. Small numbers of randomly selected single nucleotide …

Population Genetics of Sabatia Campestris (Gentianaceae), a State-Endangered Plant of the Illinois Prairie
Population genetic structure of peripheral populations of S. campestris from Illinois was investigated both within Illinois and at a regional scale. The results identified isolation by distance patterns indicating that Illinois populations differed genetically from central populations that were …

Evaluation of alpha-amylase activity and falling number for soft white and soft red wheat varieties adapted to Michigan
… evaluated for α-amylase activity and FN values. Genetic differences existed for both responses at all maturity categories in the absence of PHS induction. A clear trend was observed in the reduction of α-amylase and the increase in FN during the maturation in non-PHS conditions. For the study of …

Electrophoretic Discrimination of Species of the Muscidifurax (Hymenoptera: Pteromalidae) Complex
… techniques have been perfected for the genetic analysis of Muscidifurax. These methods reveal "fixed" genetic differences between biotypes not previously detected by the conventional methods of classification. Estimates of the phylogeny of Muscidifurax have been made that display some …

Multiple Genetic Loci Control Susceptibility and Disease Characteristics in Murine Experimental Allergic Encephalomyelitis
… different clinical subtypes of EAE are immunogenetically distinct. In addition, the severity, duration, and day of onset are genetically controlled. Lesion characteristics and location of lesions are modulated by numerous genetic factors and can be influenced by sex. Underlying genetic …

Population differences in water-use effeciency for Pinus contorta dougl as indicated by stable carbon isotopic composition
… of water-use efficiency (WUE), was used to test genetic and environmental responses of Pinus contorta Dougl. populations to moisture gradients. To gain insight into patterns of natural selection for high or low WUE, trends in 8¹³C were measured in genotypes from different habitats. Correlations …

Personalized medicine, population genetics and privacy : an empirical study of international gene banks
… and by sub-group; presumably due to fundamental genetic differences in disease and metabolic pathways. Drugs like Herceptin, Gleevec and Iressa are part of an emerging trend in the biopharmaceutical arena of drugs that are accompanied by genetic diagnostic tests and prescribed only for patients …

Sweet sorghum diversity, genetics, and breeding
… be successfully used for bioenergy production, genetic relationships and diversity within sweet sorghums should be better understood, genetic and physiological mechanisms that distinguish sweet from non-sweet sorghums need to be characterized, and higher-yielding sweet sorghum female lines are …

DNA Barcode Examination of North American Mayflies Across Their Natural Distribution Reveals Cryptic Species Complexes
… between intraspecific and interspecific differences. Therefore, criteria for delimiting species may need revision. To test whether intraspecific differences at COI are influenced by geographical scale, a COI-barcode library was constructed for three species of North American mayflies …

Understanding the Effects of Genetic Variation on Osmo-adaptation Dynamics Across S. cerevisiae using Bulk Segregant Analysis and Whole Genome Sequencing
… few studies have focused on the effects of genetic variation. Understanding how genetic variation affects molecular pathways and their dynamics, which translates to variation in cellular and organismal phenotypes, is a key step towards understanding important phenomena such as complex gene …

A genetic basis for life history differences among populations of the midge, Chironomus riparius (Diptera:Chironomidae)
… to test whether they would respond similarly, if genetically similar. or differently, if their genotypes were different. The populations were subjected to a variety of experimental conditions in the laboratory in which temperature and food quality were manipulated. The population collected from …

A Comparison of Genetic Differentiation and Gene Flow Among Populations of Two Species of Mice (Peromyscus)
… variable in P. leucopus. Results indicate that genetic similarities and differences among populations of P. attwateri are not affected by gene flow. Populations of P. leucopus tend to show genetic differences due more to isolation by distance.

Genetic epidemiology of markers of genomic ageing
… loss, have been linked to cancer. The genetic architecture of these markers is not well understood and studies investigating associations with common age-related cardiometabolic conditions have been limited in their design, analytical methods, power and genetic instruments used. Only a …

Gender differences in ADHD diagnosis
… of the disorder, neurological studies, potential genetic differences between genders, as well as potential gender biases. These topics are all examined with the purpose of trying to determine which effect, if any, they may have had in creating the criteria necessary for a diagnosis and how that …

Exploring the role of aneuploidy in phenotypic variability
… in individuals with Down syndrome. These differences have long been attributed to genetic differences within the population altering the likelihood that particular phenotypes will develop. However, work in yeast and mouse models of aneuploidy suggest that phenotypic variability can be a …
