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

A Core Head, Neck, and Neuroanatomy Syllabus for Physical Therapy Student Education

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Head, neck, and neuroanatomy are essential components of physical therapy education due to their broad clinical applications. Detailed syllabi exist for medical students, yet none have been developed for physical therapy. This study aimed to produce an International Federation of Associations of Anatomists core head, neck, and neuroanatomy ...

The Application of Carbon Dots in Crops for Sustainable Agriculture

open access: yesChemistryEurope, EarlyView.
Carbon dots serve as versatile nanoagents across the crop life cycle. They promote plant growth and photosynthesis, enhance resilience to biotic and abiotic stresses, aid in postharvest preservation, and enable sensitive detection of contaminants.

Where, When, and How? Integrating Spatiotemporal Cues in Cell Division. [PDF]

open access: yesBioessays
Accurate chromosome segregation during mitosis depends on the spatial and temporal regulation of spindle assembly, kinetochore‐microtubule attachment, and checkpoint signaling. Here, we highlight how mitotic chromosomes can serve as dynamic hubs that integrate molecular cues to coordinate spindle organization and timing, ensuring faithful genome ...

PEK14: A Kinesin‐4 Necessary for Male‐Derived Fertility in Arabidopsis thaliana

open access: yesCytoskeleton, EarlyView.
ABSTRACT Of the 61 kinesins annotated in Arabidopsis thaliana, many are still without assigned function. Here, we have screened an insertional mutant library of Arabidopsis pollen‐expressed kinesins for fertility defects. Insertional mutants for three kinesins showed a significant reduction in seed set.

Protein Kinase C Regulates Meiosis in Mammalian Oocytes. [PDF]

open access: yesBioessays
Protein kinase C (PKC) participates in the regulation of mammalian oocyte meiosis. PKC is involved in meiosis resumption in prophase I and in the stabilization of meiosis I and meiosis II spindles. PKC stimulates the maturation‐promoting factor during fertilization and stabilizes the mitotic spindle during early embryo development. ABSTRACT The protein

The mechanism of anaphase spindle elongation: uncoupling of tubulin incorporation and microtubule sliding during in vitro spindle reactivation. [PDF]

open access: yes, 1988
To study tubulin polymerization and microtubule sliding during spindle elongation in vitro, we developed a method of uncoupling the two processes. When isolated diatom spindles were incubated with biotinylated tubulin (biot-tb) without ATP, biot-tb was ...
