The myth of the metabolic baseline: sleep–wake cycles undermine a foundational assumption in organismal biology

open access: yesBiological Reviews, EarlyView.
ABSTRACT Basal and standard metabolic rate (BMR and SMR) are cornerstones of physiological ecology and are assumed to be relatively fixed intrinsic properties of organisms that represent the minimum energy required to sustain life. However, this assumption is conceptually flawed. Many core maintenance processes underlying SMR are temporally partitioned

Oocyte–cumulus cell interaction: a key factor in early embryo development

open access: yesBiological Reviews, EarlyView.
ABSTRACT The evaluation of oocyte competence is a fundamental step in achieving successful outcomes following assisted reproduction techniques (ART). At present, however, conventional oocyte maturation assessment is carried out by morphological observation, which is a subjective method that does not consider molecular features.

Protein hydrolysates in cell culture: Toward multi‐omics characterization

open access: yesBiotechnology Progress, EarlyView.
While protein hydrolysates are widely used in cell culture applications, they remain undefined and variable products. Multi‐omic characterization evaluating composition and function can transition hydrolysates toward semi‐defined media components.

Pulmonalis or Pulmonaris? It's Elementarius, My Dear Watson

open access: yesClinical Anatomy, EarlyView.
ABSTRACT The adjectival suffix ‐alis and its allomorph ‐aris are very common in the anatomical nomenclature; however, rules governing differential usage, such as ‐aris substituting for ‐alis following an ‐l‐, leave many exceptions. Here, we report an empirical study of 985 adjectives with ‐alis and ‐aris suffixes used in Terminologia Anatomica (2nd ed.)

Catabolic transposons

Biodegradation, 1994
The structure and function of transposable elements that code for catabolic pathways involved in the biodegradation of organic compounds are reviewed. Seven of these catabolic transposons have structural features that place them in the Class I (composite) or Class II (Tn3-family) bacterial elements. One is a conjugative transposon.

Surfactant catabolism

Respirology, 2006
Abstract:  Alveolar pulmonary surfactant is a complex of macromolecular aggregates composed of phospholipids and surfactant proteins (SP) that is essential for maintenance of normal lung function. The importance of surfactant homeostasis is recognized in the patients and the animal models with pulmonary disease, although the mechanisms of surfactant ...

Bacterial catabolism of nicotine: Catabolic strains, pathways and modules

Environmental Research, 2020
Nicotine, the major alkaloid in tobacco, is a toxic, carcinogenic, and addictive compound. In recent years, nicotine catabolism in prokaryotes, including the catabolic pathways for its degradation and the catabolic genes that encode the enzymes of these pathways, have been systemically investigated. In this review, the three known pathways for nicotine
