Abstract:

Freshwater snails belonging to the genus Biomphalaria are intermediate hosts of the trematode Schistosoma mansoni in the Neotropical region and Africa. In Brazil, one subspecies and ten species of Biomphalaria have been identified: B. glabrata, B. tenagophila, B. straminea, B. occidentalis, B. peregrina, B. kuhniana, B. schrammi, B. amazonica, B. oligoza, B. intermedia and B.t. guaibensis. However, only the first three species are found naturally infected with S. mansoni. The classical identification of these planorbids is based on comparison of morphological characteristics of the shell and m

Abstract:

Gossypium hirsutum is one of the main tetraploid cotton species that is cultivated throughout the world. Due to continuous selection of cotton cultivars for specific agronomic traits, the genetic variability within the cultivars decrease that lead to genetic erosion. To tackle the problem of reduced genetic variability, we should track all available genetic diversity within cotton germplasm and use them for inter-specific and intra-specific hybridization and produce new elite cotton cultivars. Therefore, the present study used ISSR molecular markers to illustrate genetic variability in 13 tetr

Abstract:

In this work, the anatomical variability in Artemisia herba-alba Asso was studied based on 90 individuals taken from three different bioclimatic zones of Algeria (inferior semi arid, arid and Saharan) as well as the relationships of the dynamics of this variability with the distribution and adaptation of the species. The interpretation of the results of this study through the analysis of variance and the ascending hierarchical classification allowed us to detect a very high intra- and inter-specific anatomical variability, as well as the presence of a parenchyma of water reserves observed in i

Abstract Background: Genomic sequencing data from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have provided important information on the emergence of variants of interest. Some research has focused on determining intra-host variability and evolution, and others have focused on viral genetic variability in different tissues, as well as implications for virus infectivity and pathogenicity. However, the inter-host variability of SARS-CoV-2 in respiratory compartments and its implications has not yet been explained. To determine a possible pattern of tissue-specific inter-host var

Abstract:

Studies of climate change effects on individuals and populations are mostly couched in terms of lethal temperature limits, but 2 other elements make predictions difficult: the effects of sublethal stress and intraspecific variability. Sublethal stress, such as exposure to highly variable temperatures, can cause carryover effects that influence how an animal responds to subsequent events and its long-term fitness. Additionally, intra-specific genetic variability can allow more complex species responses to climate change. We used 2 genetically distinct lineages of the intertidal mussel Perna per

Cytogenetics, which is considered a fundamental tool to understand basic genetic and genomic issues of species, has greatly contributed to the description of polymorphisms both at inter- and intra-specific level.

Different morphological variants of sex chromosomes have been reported among Argentinean populations of A. fraterculus. However, since this high structural variability in sex chromosomes does not pose a reproductive barrier, their role in

It is very important to compute the mutation spectra, and simulate the intra-host mutation processes by sequencing data, which is not only for the understanding of SARS-CoV-2 genetic mechanism, but also for epidemic prediction, vaccine, and drug design. However, the current intra-host mutation analysis algorithms are not only inaccurate, but also the simulation methods are unable to quickly and precisely predict new SARS-CoV-2 variants generated from the accumulation of mutations. Therefore, this study proposes a novel accurate strand-specific SARS-CoV-2 intra-host mutation spectra computation

In addition, technical factors in slide preparation and digitization can also contribute to variability.

To account for inter-individual variability in CD8 T cell responses in mice, we propose a dynamical model coupled to a statistical, nonlinear mixed effects model.
