Histology and fossil diagenesis of a pterosaur tooth from the Crato Formation (Lower Cretaceous of Brazil)

The Anatomical Record, EarlyView.
Abstract Pterosaur dental biology remains poorly understood despite its importance for comprehending feeding strategies and flight adaptations. Here, we present the first comprehensive histological analysis of an ornithocheiriform pterosaur tooth from the Lower Cretaceous Crato Formation (Santana Group, Northeast Brazil).

ROS production and scavenging under anoxia and re-oxygenation in Arabidopsis cells: a balance between redox signaling and impairment.

Frontiers in Plant Science, 2016
Plants can frequently experience low oxygen concentrations due to environmental factors such as flooding or waterlogging. It has been reported that both anoxia and the transition from anoxia to re-oxygenation determine a strong imbalance in the cellular ...

Therapeutic drug monitoring of antimicrobials in a paediatric setting: A retrospective single‐centre study

British Journal of Clinical Pharmacology, EarlyView.
Aims Paediatric pharmacokinetics differ significantly from adults due to age‐related physiological changes, necessitating precise dose adjustments. However, data on therapeutic drug monitoring (TDM) implementation in paediatric setting remain limited.

Influence of Zn2+ and Oxygen Supply on Malic Acid Production and Growth of Aspergillus oryzae

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Malic acid is a valuable platform chemical traditionally derived from fossil‐based resources. Microbial cultivation with Aspergillus oryzae offers a sustainable alternative based on renewable feedstocks. In this study, a well‐established minimal medium for malic acid production, commonly used in previous research to ensure reproducibility, was

Nitrous Oxide Emissions from Paddies: Understanding the Role of Rice Plants

Plants, 2020
Paddies are a potential source of anthropogenic nitrous oxide (N2O) emission. In paddies, both the soil and the rice plants emit N2O into the atmosphere.

The effect of reducing ATP levels on reorientation of the secondary palate [PDF]

, 1986
The force for directing palate shelf reorientation appears to be associated with elements of the presumptive hard palate (Brinkley & Vickerman, 1979; Bulleit & Zimmerman, 1985).

Lactate-proton co-transport and its contribution to interstitial acidification during hypoxia in isolated rat spinal roots [PDF]

, 1993
Exposure of nervous tissue to hypoxia results in interstitial acidification. There is evidence for concomitant decrease in extracellular pH to the increase in tissue lactate.

An Idea to Explore: From How to Why: Using Evolutionary Biochemistry to Inspire Biochemistry Education

Biochemistry and Molecular Biology Education, EarlyView.
ABSTRACT Traditional biochemistry instruction often emphasizes mechanistic detail, that is, how molecules and pathways function, without equally addressing why they have their present forms. This fact‐centered approach can leave students overwhelmed and disconnected from the broader scientific narrative.
