Understanding extracellular vesicles in antiaging
Periodontology 2000, EarlyView.Abstract Background Aging is a multifactorial process marked by gradual cellular dysregulation, regulated by hallmarks, including genomic instability, mitochondrial dysregulation, and chronic inflammation. Extracellular vesicles (EVs), especially exosomes, have emerged as pivotal mediators of cell‐to‐cell communication with potential roles in both ...

Renaissance Studies, EarlyView.ABSTRACT Native to America, the pineapple—Ananas comosus (L.) Merr.—delighted the Europeans who came across it. The fruit was mentioned by the voyagers and missionaries who observed and tasted it in the Americas and, from the 1500s onwards, infused reports, chronicles and natural history treatises with colour and flavour.

Navigating Traditional‐Modernity: Women's Evolving Role in Qatar's National Identity
Studies in Ethnicity and Nationalism, EarlyView.ABSTRACT This article critically examines the evolving role of women in Qatar's nation‐building project through a combination of intersectional and post‐colonial perspectives. By analysing women's socio‐political positioning in the national context, it unveils the complex interplay between conceptualisations of ‘tradition’ and ‘modernity’ in shaping ...

Experimental Physiology, EarlyView.Abstract Cerebral blood flow (CBF) is essential for sustaining neuronal metabolism and cognitive performance; however, the precise relationship between perfusion and cognition remains unclear. Although ageing and disease are associated with progressive declines in CBF and cognitive impairment, the acute effects of altered CBF under environmental ...

Experimental Physiology, EarlyView.Abstract Sympathetic nervous system activation is a hallmark of high‐altitude hypoxia, yet the afferent mechanisms remain incompletely defined. We examined the relative contributions of pulmonary arterial mechanoreceptors and carotid chemoreceptors – two excitatory pathways co‐activated by hypoxia – to sustained sympathoexcitation at altitude.

Intermittent hypoxia interventions for inducing ventilatory acclimatization to high altitude?
Experimental Physiology, EarlyView.Abstract Accumulation of ∼200 h of hypoxia exposure (pre‐acclimatization) has been suggested to prevent the development of acute mountain sickness when a person is subsequently exposed to high altitude. These pre‐exposures are typically undertaken intermittently at or near the place of residence, primarily during sleep in hypoxic tents, and are likely ...

Quantitative MRI changes in neck muscle size and composition following long‐duration spaceflight
Experimental Physiology, EarlyView.Abstract Long‐duration spaceflight poses several challenges to human health, including muscle loss and fat deposition. To mitigate these effects, exercise countermeasures are prescribed. This study aimed to measure neck muscle size and composition changes with long‐duration spaceflight using quantitative magnetic resonance imaging (MRI) and examine ...
