Database of low‐temperature absorption and fluorescence spectra of native photosynthetic tetrapyrrole macrocycles

open access: yesPhotochemistry and Photobiology, EarlyView.
The absorption and fluorescence spectra at 77 K (frozen glass) and room temperature (fluid solution) are provided for 12 native photosynthetic macrocycles encompassing one porphyrin, eight chlorins, and 3 bacteriochlorins. Abstract Low‐temperature (77 K) absorption and fluorescence spectra of 12 naturally occurring photosynthetic tetrapyrrole ...

Prognostic Value of Magnetic Resonance Imaging Defined Extent of Surgical Resection in Dogs With Intracranial Meningiomas

open access: yesVeterinary and Comparative Oncology, EarlyView.
ABSTRACT Surgery is a common treatment for intracranial meningiomas in dogs, although the prognostic impact of the extent of resection (EOR) has not been systematically evaluated. This retrospective study identified prognostic factors associated with clinical outcomes in dogs that underwent surgery and early post‐operative magnetic resonance imaging ...

Human adaptation to high‐altitude: A contemporary comparison of the oxygen cascade in Andean, Tibetan and Ethiopian highlanders

open access: yesExperimental Physiology, EarlyView.
Abstract Human populations native to high altitude have evolved distinct physiological adaptations to chronic hypoxia. This adaptation is evident in the O2 transport cascade. In this review, with brief inclusion of the related genetic adaptations, we compare the O2 cascade across three well‐characterized high‐altitude populations: Andeans (Aymara and ...
