Heat treatment duration affects in vitro‐induced photosynthetic impairment and development of necrotic leaf tissue in three Mediterranean oak species

open access: yesPlant Biology, EarlyView.
Longer lasting heat treatment durations induced photosynthetic impairment at lower temperatures and caused the development of proportionally more necrotic tissue at lower temperatures in leaves of three Mediterranean oak species. Abstract Short heat treatments are commonly used to estimate the leaf‐level thermal tolerance of tree species. The effect of

On the relationship between Photosystem II thermotolerance and irreversible heat damage in leaves of Rhizophora mangle

open access: yesPlant Biology, EarlyView.
Temperature‐F0 fluorescence curves of Rhizophora mangle leaves demonstrate that Tcrit, the temperature at which F0 begins to rise, is unrelated to tissue necrosis; irreversible leaf damage starts to occur at significantly higher temperatures where fluorescence emission is maximal. Abstract Global temperatures are on the rise and may, together with more

The oral microbiota and periodontal health in orthodontic patients

open access: yesPeriodontology 2000, EarlyView.
Abstract The oral microbiota develops within the first 2 years of childhood and becomes distinct from the parents by 4 years‐of‐age. The oral microbiota plays an important role in the overall health/symbiosis of the individual. Deviations from the state of symbiosis leads to dysbiosis and an increased risk of pathogenicity.

A Qualitative Study of Divergent Workplace Practices Following South Korea's 52‐h Working Time Reform

open access: yesSocial Policy &Administration, EarlyView.
ABSTRACT South Korea is known for its strong work‐centric culture, having long recorded some of the longest working hours in the OECD based on its norm of overtime work. Against this backdrop, the 52‐h working time reform, consisting of 40 standard and 12 overtime hours, was introduced in 2018.

The double modal construction in English world wide

open access: yesWorld Englishes, EarlyView.
Abstract The dual foci of the present study of double modals are their semantic characteristics and their distribution across regional varieties of English world wide. Tokens were extracted from GloWbE:Blogs, a database whose great size and informal tenor facilitated the investigation of this low‐frequency non‐standard feature. Double modals were found

Superlative Objoid Constructions in British and American English

open access: yesWorld Englishes, EarlyView.
ABSTRACT This paper investigates regional variation in Superlative Objoid constructions (SOCs) and their prepositional variant (at‐SOCs). SOCs combine a possessive pronoun with a superlative adjective. These function as manner‐degree modifiers in a context where the possessive is in postverbal position and correlative with the subject, as in they tried

Microgravity‐induced changes in skeletal muscle and possible countermeasures: What we can learn from bed rest and human space studies

open access: yesExperimental Physiology, EarlyView.
Abstract Despite exercise countermeasures to sustain health and performance in spaceflight, complete maintenance of muscle mass and functions in microgravity is still not possible for most astronauts. The principal cause of the limited effectiveness of existing exercise countermeasures is the difficulty in achieving full loading forces in space.

Hypoxia and hypercapnia elicit overlapping but distinct skeletal muscle toxicities

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Hypoxia and hypercapnia cause overlapping skeletal muscle phenotypes, including atrophy, change in myofibre metabolic profile and myogenic response to injury. Both signals operate via distinct cellular pathways. Abstract Skeletal muscle dysfunction is strongly associated with elevated mortality in acute and chronic pulmonary ...
