Vascular remodeling of the mouse yolk sac requires hemodynamic force [PDF]

open access: yes, 2007
The embryonic heart and vessels are dynamic and form and remodel while functional. Much has been learned about the genetic mechanisms underlying the development of the cardiovascular system, but we are just beginning to understand how changes in heart ...

Cardiovascular Plasticity and Adaptation of High‐Altitude Birds and Mammals

open access: yesIntegrative Zoology, EarlyView.
This schematic depicts the cardiovascular adaptations of mammals and birds to high‐altitude hypoxia. It highlights key phenotypic changes in oxygen transport and cardiac responses, driven by molecular mechanisms including transcriptional regulation and genetic modifications.

Does Sickle Cell Anaemia Have a Relationship With Avascular Pulp Necrosis? A Systematic Review

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT This systematic review examined the relationship between sickle cell disease (SCD), an inherited genetic hemoglobinopathy, and avascular pulp necrosis (APN) in intact teeth. A comprehensive search of eight electronic databases was performed up to December 2024.

Inhibition of translation by poliovirus: Inactivation of a specific initiation factor [PDF]

open access: yes, 1978
Translation of vesicular stomatitis virus (VSV) mRNA, like host mRNA translation, is inhibited in cells infected with poliovirus. To study the mechanism of poliovirus-induced inhibition of protein synthesis, we prepared extracts from poliovirus-infected ...

The role of iron in normal and impaired testicular function

open access: yesAndrology, EarlyView.
Abstract Iron plays a critical role in testicular physiology, impacting spermatogenesis, testosterone production, and overall testicular function. Iron homeostasis is maintained through systemic and cellular regulatory mechanisms, including hepcidin‐mediated systemic iron control and the iron‐responsive element/iron regulatory protein (IRE/IRP) system ...

The Steady-State Transport of Oxygen through Hemoglobin Solutions [PDF]

open access: yes, 1966
The steady-state transport of oxygen through hemoglobin solutions was studied to identify the mechanism of the diffusion augmentation observed at low oxygen tensions. A novel technique employing a platinum-silver oxygen electrode was developed to measure

New biosensors and transgenic mice for multiplex cGMP imaging

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose Cyclic guanosine monophosphate (cGMP) is a versatile second messenger that is important for human (patho‐)physiology and pharmacotherapy. Live‐cell imaging of cGMP with biosensors allows to elucidate its spatiotemporal dynamics in real time under close‐to‐native conditions. However, to monitor two separate cGMP pools or cGMP/cAMP

Maternal haemoglobin concentrations before and during pregnancy and stillbirth risk: A population-based case-control study [PDF]

open access: yes, 2016
Background: Results of previous studies on the association between maternal haemoglobin concentration during pregnancy and stillbirth risk are inconclusive. It is not clear if haemoglobin concentration before pregnancy has a role.

A century of theories of balancing selection

open access: yesBiological Reviews, EarlyView.
ABSTRACT Traits that affect organismal fitness are often highly genetically variable. This genetic variation is vital for populations to adapt to their environments, but it is also surprising given that nature – after all – ‘selects’ the best genotypes at the expense of those that fall short.
