The Eastern Mediterranean fish fauna from the Piacenzian deposits of Polis Graben (Cyprus Island)
(2022-04)The Mediterranean fish fauna has been affected by the basin changing connections with surrounding seas and climatic changes throughout the geological history of the region. During the Eocene, the area corresponding to the ...

Ecological constraints from incumbent clades drive trait evolution across the tree-of-life of freshwater macroinvertebrates
(2018)The rates of species and trait diversification vary across the Tree-of-Life and over time. Whereas species richness and clade age generally are decoupled, the correlation of accumulated trait diversity of clades (trait ...

Article
Ectopic expression of individual E(spl) genes has differential effects on different cell fate decisions and underscores the biphasic requirement for Notch activity in wing margin establishment in Drosophila
(1999)A common consequence of Notch signalling in Drosophila is the transcriptional activation of seven Enhancer of split [E(spl)] genes, which encode a family of closely related basic-helix-loop-helix transcriptional repressors. ...

The effect of fire on ant assemblages does not depend on habitat openness but does select for large, gracile predators
(2021-06-09)Ecosystems can respond in a variety of ways to the same agent of disturbance. In some con-texts,fire causes large and long-lasting changes to ecological communities. In others,fire has a limited orshort-lived impact on ...

Effect of recent thymic emigrants on progression of HIV-1 disease
(2000)Background. The concentration of T-cell receptor-rearrangement excision DNA circles (TREC) in peripheral-blood T cells is a marker of recent thymic emigrant αβ T cells. We studied the predictive ability of measurements of ...

The effect of the phytoestrogens genistein, daidzein, and equol on the growth of tamoxifen-resistant T47D/PKCα
(2007)Soy supplements are often consumed by women for alleviating menopausal symptoms or for the perceived protective effects against breast cancer. More concerning is the concurrent consumption of soy isoflavones with tamoxifen ...

The effect of topoisomerase inhibitors on the expression of differentiation markers and cell cycle progression in human K-562 leukemia cells
(1992)Treatment of human K-562-J leukemia cells for 1 h with the topoisomerase II-reactive drugs VP-16, VM-26, or mAMSA resulted in a dose-dependent inhibition of proliferation and in an increase in the percentage of cells ...

The effects of applying cell-suppression and perturbation to aggregated genetic data
(2012)The key test for confidence in any association discovered within the medical domain is replication testing. That is, the ability of the association to be detected in independent populations. At the same time, in order to ...

Effects of CCR5-Δ32, CCR2-64I, and SDF-1 3′ a alleles on HIV-1 disease progression: An international meta-analysis of individual-patient data
(2001)Background: Studies relating certain chemokine and chemokine receptor gene alleles with the outcome of HIV-1 infection have yielded inconsistent results. Objective: To examine postulated associations of genetic alleles ...

Effects of in Vivo CD8+ T cell depletion on virus replication in rhesus macaques immunized with a live, attenuated simian immunodeficiency virus vaccine
(2000)The role of CD8+ T lymphocytes in controlling replication of live, attenuated simian immunodeficiency virus (SIV) was investigated as part of a vaccine study to examine the correlates of protection in the SIV/rhesus macaque ...

Efficacy of garbanzo and soybean flour in suppression of aberrant crypt foci in the colons of CF-1 mice
(2004)Background: Epidemiological studies have reported a low incidence of colon cancer in countries with high legume consumption. Moreover, experimental studies have found that legumes, such as soybeans and pinto beans, have ...

Embryonic multipotent progenitors remodel the Drosophila airways during metamorphosis
(2010)Adult structures in holometabolous insects such as Drosophila are generated by groups of imaginal cells dedicated to the formation of different organs. Imaginal cells are specified in the embryo and remain quiescent until ...

Emergence of drug-resistant HIV-1 variants in patients undergoing structured treatment interruptions
(2002)We report the emergence of drug-resistant viral mutations in chronically HIV-infected individuals undergoing structured treatment interruptions (STI). The protease mutation M46L and the reverse transcriptase mutations K101E ...

Emergence of Minor Populations of Human Immunodeficiency Virus Type 1 Carrying the M184V and L90M Mutations in Subjects Undergoing Structured Treatment Interruptions
(2003)The use of structured treatment interruption (STI) in human immunodeficiency virus (HIV)-infected subjects is currently being studied as an alternative therapeutic strategy for HIV-1. The potential risk for selection of ...

An energy-efficient and error-resilient server ecosystem exceeding conservative scaling limits
(2018)The explosive growth of Internet-connected devices will soon result in a flood of generated data, which will increase the demand for network bandwidth as well as compute power to process the generated data. Consequently, ...

Environment shapes the digestive performance in a Mediterranean lizard
(2017)An efficient digestive system is of pivotal importance for survival as it governs the energy flow from the environment to organisms. Reptiles require relatively little energy, and their digestive system can readily respond ...

Epistatic Role of the MYH9/APOL1 Region on Familial Hematuria Genes
(2013)Familial hematuria (FH) is explained by at least four different genes (see below). About 50% of patients develop late proteinuria and chronic kidney disease (CKD). We hypothesized that MYH9/APOL1, two closely linked genes ...
