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.

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.

American Exceptionalism: Population Trends and Flight Initiation Distances in Birds from Three Continents [PDF]

open access: yesPLoS ONE, 2014
Background All organisms may be affected by humans' increasing impact on Earth, but there are many potential drivers of population trends and the relative importance of each remains largely unknown. The causes of spatial patterns in population trends and

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

open access: yesCurrent Biology, 2021
Summary Like 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

Incorporating dynamic flight network in SEIR to model mobility between populations [PDF]

open access: yesApplied Network Science, 2021
AbstractCurrent efforts of modelling COVID-19 are often based on the standard compartmental models such as SEIR and their variations. As pre-symptomatic and asymptomatic cases can spread the disease between populations through travel, it is important to incorporate mobility between populations into the epidemiological modelling.

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 ...

Cancer prevalence among flight attendants compared to the general population [PDF]

open access: yesEnvironmental Health, 2018
Flight attendants are an understudied occupational group, despite undergoing a wide range of adverse job-related exposures, including to known carcinogens. In our study, we aimed to characterize the prevalence of cancer diagnoses among U.S. cabin crew relative to the general population.In 2014-2015, we surveyed participants of the Harvard Flight ...

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 ...

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
