Circadian regulation of reproduction and neoblast cell division in the catenulid flatworm Stenostomum virginianum (Platyhelminthes)

open access: yesPhotochemistry and Photobiology, EarlyView.
The circadian clock and melatonin coordinate homeostasis in many animals, yet their influence on reproduction and neoblast proliferation has only been shown in triclads. This study demonstrates that the early‐branching catenulid Stenostomum virginianum contains photoreceptive refractile bodies, synthesizes endogenous melatonin, and that exogenous ...

A Crazy Idea: Ibn Sīnā on Hylomorphism, the Elements, Mixture and Evolutionary Processes

open access: yesTheoria, EarlyView.
ABSTRACT Ibn Sīnā (c. 973‐1037), the Avicenna of Latin fame, developed a unique theory of the elements and their status in mixtures that severely challenged the views of earlier natural philosophers and in its turn was severely challenged by later Latin Schoolmen in the West.

Impact of Advanced Age on Posttransplant Infections and Outcomes in Solid Organ Transplant Recipients: A Multicenter Cohort Study

open access: yesTransplant Infectious Disease, EarlyView.
Advanced age (≥60 years) was independently associated with higher mortality in solid organ transplant recipients, despite similar infection incidence. Even a single infection episode significantly increased mortality risk, underscoring the need for close clinical monitoring in elderly patients.

Integrative Phosphoproteomic Profiling Reveals Stage‐Specific Signalling and Metabolism in Equine Melanocytic Neoplasm

open access: yesVeterinary and Comparative Oncology, EarlyView.
ABSTRACT Equine melanocytic neoplasms (EMN) are aggressive tumours characterised by high metastatic potential and limited therapeutic options available. However, the molecular mechanisms underlying their progression remain poorly understood. This study therefore presents the integrative phosphoproteomic analysis of EMN tissue, with the aim of ...

Low‐dose X‐ray radiation induces an adaptive response: A potential countermeasure to galactic cosmic radiation exposure

open access: yesExperimental Physiology, EarlyView.
Abstract Space exploration involves many dangers including galactic cosmic radiation (GCR). This class of radiation includes high‐energy protons and heavy ionizing ions. NASA has defined GCR as a carcinogenic risk for long‐duration space missions. To date, no clear strategy has been developed to counter chronic GCR exposure.

Effects of tempol on renal medullary tissue hypoxia in an ovine model of Gram‐negative septic acute kidney injury

open access: yesExperimental Physiology, EarlyView.
Abstract Renal arterial infusion of tempol (RAT) at the onset of Gram‐negative sepsis can prevent sepsis‐induced medullary tissue hypoxia and acute kidney injury (AKI). However, it is not known whether treatment with tempol at a clinically relevant time point of sepsis is similarly effective. Thus, we examined whether tempol can reverse renal medullary

Pregnancy shifts endothelial progenitor cell morphology and function: Role of metabolism, pro‐inflammatory cytokines and fetal sex

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend We recruited non‐pregnant women (NP), women in early pregnancy (EP) and late pregnancy (LP) for isolation of endothelial colony forming cells (ECFCs) via density gradient centrifugation. Plasma supernatant was collected for analysis of markers of glucose and lipid metabolism (fasting glucose, triglycerides, cholesterol, low ...
