Estimating the health consequences of flight attendant work: comparing flight attendant health to the general population in a cross-sectional study [PDF]

open access: yesBMC Public Health, 2018
Background Flight attendants are an understudied occupational group, despite undergoing a wide and unique range of adverse job-related exposures. In our study, we aimed to characterize the health profile of cabin crew relative to the U.S.

Identification of a new stem cell population that generates Drosophila flight muscles

open access: yeseLife, 2014
How myoblast populations are regulated for the formation of muscles of different sizes is an essentially unanswered question. The large flight muscles of Drosophila develop from adult muscle progenitor (AMP) cells set-aside embryonically.

The self-reported health of U.S. flight attendants compared to the general population [PDF]

open access: yesEnvironmental Health, 2014
Background: Few studies have examined the broad health effects of occupational exposures in flight attendants apart from disease-specific morbidity and mortality studies.

A population of descending neurons that regulates the flight motor of Drosophila [PDF]

open access: yesCurrent Biology, 2021
SummaryLike many insect species, Drosophila melanogaster are capable of maintaining a stable flight trajectory for periods lasting up to several hours(1, 2). Because aerodynamic torque is roughly proportional to the fifth power of wing length(3), even small asymmetries in wing size require the maintenance of subtle bilateral differences in flapping ...

Population Biology of Lymphocytes: The Flight for Survival [PDF]

open access: yesAnnual Review of Immunology, 2000
In this essay we suggest that the primary goal of the cells of the immune system is to ensure their own growth and survival. In adults, in steady-state conditions, the number and distribution of lymphocyte populations is under homeostatic control. New lymphocytes that are continuously produced in primary and secondary lymphoid organs must compete with ...

Hearing Health Risk in a Population of Aircraft Carrier Flight Deck Personnel [PDF]

open access: yesMilitary Medicine, 2004
This study evaluated the risk to hearing health associated with duty on the flight deck of a Nimitz class aircraft carrier. Descriptive data includes time-weighted average noise exposure and an evaluation of temporary threshold shift for a group of nonaviator flight deck personnel (FD), and a comparison of accrued permanent threshold shift among three ...

Sex specificity of dispersal behaviour and flight morphology varies among tree hollow beetle species

open access: yesMovement Ecology, 2022
Background Flight performance and dispersal behaviour can differ between sexes, resulting in sex-biased dispersal. The primary sex ratio of populations may also explain dispersal bias between sexes, as this bias may evolve with the primary sex ratio to ...

Internal sensations as a source of fear: exploring a link between hypoxia and flight phobia [PDF]

open access: yes, 2013
Although flight phobia is very common in the general population, knowledge of the underlying mechanisms is limited. The aim of the current study is to determine whether hypoxia is selectively associated with flight anxiety. We wanted to explore levels of

Differences in the Aerobic Capacity of Flight Muscles between Butterfly Populations and Species with Dissimilar Flight Abilities

open access: yesPLoS ONE, 2014
Habitat loss and climate change are rapidly converting natural habitats and thereby increasing the significance of dispersal capacity for vulnerable species. Flight is necessary for dispersal in many insects, and differences in dispersal capacity may reflect dissimilarities in flight muscle aerobic capacity.

Cancer risks from cosmic radiation exposure in flight: A review

open access: yesFrontiers in Public Health, 2022
Aircrew (consisting of flight attendants, pilots, or flight engineers/navigators) are exposed to cosmic ionizing radiation (CIR) at flight altitude, which originates from solar activity and galactic sources.
