On the epidemiology, biology and food-dependent reproduction of the feral pigeon (Columba livia) [PDF]

open access: yes, 2015
Millions of feral pigeons (Columba livia, Gmelin 1789) live in close association with the human population in our cities. They have managed to adapt extremely well to city life.

Treatment with Docosahexaenoic Acid Improves Epidermal Keratinocyte Differentiation and Ameliorates Inflammation in Human Keratinocytes and Reconstructed Human Epidermis Models

open access: yesMolecules, 2019
Atopic dermatitis (AD) is a chronic inflammatory skin disease that can cause skin barrier function damage. Although co-incubation with docosahexaenoic acid (DHA) exerts a positive effect on deficient skin models, no studies have investigated the effects ...

Relevance of skin-prick test and immunoglobulin E estimation in pigeon-exposure asthma patients

open access: yesEgyptian Journal of Chest Disease and Tuberculosis, 2021
Background Pigeon exposure is common in India due to its cultural and religious practice. Hypersensitivity to pigeon allergen is well known as pigeon breeder disease. Limited data also show that pigeon allergen was associated with increased asthma.

REFLEXIVITY IN PIGEONS [PDF]

open access: yesJournal of the Experimental Analysis of Behavior, 2010
A recent theory of pigeons' equivalence‐class formation (Urcuioli, 2008) predicts that reflexivity, an untrained ability to match a stimulus to itself, should be observed after training on two “mirror‐image” symbolic successive matching tasks plus identity successive matching using some of the symbolic matching stimuli. One group of pigeons was trained

Passaging of a Newcastle disease virus pigeon variant in chickens results in selection of viruses with mutations in the polymerase complex enhancing virus replication and virulence [PDF]

open access: yes, 2010
Some Newcastle disease virus (NDV) variants isolated from pigeons (pigeon paramyxovirus type 1; PPMV-1) do not show their full virulence potential for domestic chickens but may become virulent upon spread in these animals.

Rapid detection of pigeon Megrivirus using TaqMan real-time PCR technology

open access: yesPoultry Science, 2023
: Megriviruses have been identified from fecal samples in wild pigeons in Hong Kong (China) and Hungary. In this study, the genomic sequences of pigeon Megriviruses (PiMeVs) were downloaded from GenBank and compared.

On the biology and epidemiology of the feral pigeon (Columba livia) [PDF]

open access: yes, 2013
Feral pigeons (Columba livia, Gmelin 1789) are among the most abundant vertebrates in the urban environment of almost every city in the world. Close contacts to humans bear the risk of transmission of zoonotic pathogens and parasites.

Identification of potential hub genes associated with atopic dermatitis-like recombinant human epidermal model using integrated transcriptomic and proteomic analysis

open access: yesBiomolecules & Biomedicine
Atopic dermatitis (AD) is a severe inflammatory skin disorder, characterized by elevated levels of proinflammatory cytokines that fuel a vicious cycle of inflammation.
