Cerebral oxygen extraction across different exercise intensities: Role of arterial PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_2}}}$

open access: yesExperimental Physiology, EarlyView.
Abstract Stability in cerebral oxygen extraction fraction (OEF) is typically determined by alterations in cerebral blood flow (CBF). At rest, arterial partial pressure of carbon dioxide (PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$) and OEF exhibit a strong inverse relationship owing to the powerful influence of PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$

Pulmonary arterial mechanoreceptors mediate sustained sympathoexcitation during high altitude hypoxia in humans

open access: yesExperimental 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.

Daily hot‐water immersion preserves altitude‐induced haemoglobin mass expansion following descent independent of erythropoietin

open access: yesExperimental Physiology, EarlyView.
Abstract High‐altitude exposure increases haemoglobin mass (Hbmass), a key determinant of arterial oxygen‐carrying capacity, but following descent this adaptation can regress toward baseline within 7 days. Long‐term heat acclimation has emerged as an alternative stimulus for Hbmass expansion; however, whether post‐altitude passive‐heat exposure can ...

Hybrid Communication Architecture HCA

open access: yes, 2014
The beginning of the 21st century has seen many projects on distributed hash tables, both research and commercial. One of their aims has been to replace the first generation of file sharing software with scalable peer-to-peer architectures. On other fronts, the same techniques are applied, for example, to content delivery networks, streaming networks ...

Maximal exercise at high altitude does not exacerbate inflammation in the human brain

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend This study investigated arterial–internal jugular venous (IJV) exchange of cytokines in response to low‐intensity and maximal cycling exercise at sea level and following 6–8 days at 3800 m a.s.l. There was a shift towards net release of interleukin‐6 (IL‐6), interleukin‐8 (IL‐8), monocyte chemoattractant protein‐1 (MCP‐1) and ...

Impact of Crude Oil Contamination on Green Leafy Vegetables: Nutritional and Health Risk Assessments

open access: yesRemediation Journal, Volume 36, Issue 2, Spring 2026.
ABSTRACT For decades, crude oil spills have been a serious environmental challenge which have led to the establishment of crude oil remediation intervention values (CRIV) by different national agencies to regulate the release of toxic petroleum hydrocarbons via these spills.

Metabolome analysis identified exogenous cholesterol within lipid rafts that activate the Akt/mTOR signaling pathway in epithelial ovarian cancer

open access: yesInternational Journal of Cancer, Volume 159, Issue 1, Page 257-268, 1 July 2026.
What's New? Epithelial ovarian cancer (EOC) is a severe malignancy with few effective treatment options. While the mechanisms remain unclear, changes in lipid metabolism may fuel tumor growth and EOC progression, offering a possible path for new treatments.
