Imprinting Mechanisms [PDF]

open access: yesGenome Research, 1998
A number of recent studies have provided new insights into mechanisms that regulate genomic imprinting in the mammalian genome. Regions of allele-specific differential methylation (DMRs) are present in all imprinted genes examined. Differential methylation is erased in germ cells at an early stage of their development, and germ-line-specific ...

Low-Cost Surface Enhanced Raman Scattering for Bio-Probes

open access: yesSolids, 2022
Raman Spectroscopy is a well-known method for identifying molecules by their spectroscopic “fingerprint”. In Surface Enhanced Raman Scattering (SERS), the presence of nanometallic surfaces in contact with the molecules enormously enhances the ...

The coevolution of sexual imprinting by males and females

open access: yesEcology and Evolution, 2016
Sexual imprinting is the learning of a mate preference by direct observation of the phenotype of another member of the population. Sexual imprinting can be paternal, maternal, or oblique if individuals learn to prefer the phenotypes of their fathers ...

The Effects of Imprinting and Repeated Seasonal Influenza Vaccination on Adaptive Immunity after Influenza Vaccination

open access: yesVaccines, 2020
(1) Background: The influenza virus continues to cause significant annual morbidity and mortality. The overall efficacy of seasonal influenza vaccination is suboptimal, which is partly due to host immune factors.

Parental behavior and newborn attachment in birds: life history traits and endocrine responses

open access: yesFrontiers in Psychology, 2023
In birds, parental care and attachment period differ widely depending on the species (altricial or precocial), developmental strategies, and life history traits.

Do social insects support Haig's kin theory for the evolution of genomic imprinting?

open access: yesEpigenetics, 2017
Although numerous imprinted genes have been described in several lineages, the phenomenon of genomic imprinting presents a peculiar evolutionary problem.

B Cell Responses against Influenza Viruses: Short-Lived Humoral Immunity against a Life-Long Threat

open access: yesViruses, 2021
Antibodies are critical for providing protection against influenza virus infections. However, protective humoral immunity against influenza viruses is limited by the antigenic drift and shift of the major surface glycoproteins, hemagglutinin and ...

The Algorithmic Imprint

open access: yes2022 ACM Conference on Fairness Accountability and Transparency, 2022
When algorithmic harms emerge, a reasonable response is to stop using the algorithm to resolve concerns related to fairness, accountability, transparency, and ethics (FATE). However, just because an algorithm is removed does not imply its FATE-related issues cease to exist.

Sexual imprinting of offspring on their parents and siblings

open access: yesCogent Psychology, 2017
Based on data provided anonymously by 2,611 women and 1,452 men using a computerized questionnaire, we found that 19.2% of women vs. 16% of men (p
