A formal theory for spatial representation and reasoning in biomedical ontologies [PDF]

open access: yes, 2006
Objective: The objective of this paper is to demonstrate how a formal spatial theory can be used as an important tool for disambiguating the spatial information embodied in biomedical ontologies and for enhancing their automatic reasoning capabilities ...

Linked dimers of the AAA+ ATPase Msp1 reveal energetic demands and mechanistic plasticity for substrate extraction from lipid bilayers

open access: yesFEBS Letters, EarlyView.
Cells must clear mislocalized or faulty proteins from membranes to survive. The AAA+ ATPase Msp1 performs this task, but dissecting how its six subunits work together is challenging. We engineered linked dimers with varied numbers of functional subunits to reveal how Msp1 subunits cooperate and use energy to extract proteins from the lipid bilayer ...

Of tissue blocks and higher anatomy: A typical day in the life of a BSc (Anatomy) student

open access: yesThe Annals of African Surgery, 2008
A chance to slow the frenetic pace of the day that was, I shed my shoes and slip into the sweet embrace of my blankets. With one eye and a tired thumb I key in ‘6.30 AM’ into my alarm…’Wishful thinking’ I say to myself.

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Antioxidative properties of Nauclea latifolia (African peach) extracts protects against sodium arsenite-induced oxidative damage in hepatorenal tissues in Wistar rats

open access: yesJournal of Basic and Applied Zoology
Background Food and water serve as the primary sources of arsenic exposure, posing one of the most significant health threats related to heavy metals. Arsenic causes oxidative stress, which has many negative effects on humans.

Anatomical information science [PDF]

open access: yes, 2005
The Foundational Model of Anatomy (FMA) is a map of the human body. Like maps of other sorts – including the map-like representations we find in familiar anatomical atlases – it is a representation of a certain portion of spatial reality as it exists at ...

Photosynthesis under far‐red light—evolutionary adaptations and bioengineering of light‐harvesting complexes

open access: yesFEBS Letters, EarlyView.
Phototrophs evolved light‐harvesting systems adapted for efficient photon capture in habitats enriched in far‐red radiation. A subset of eukaryotic pigment‐binding proteins can absorb far‐red photons via low‐energy chlorophyll states known as red forms.

Recent origin of low trabecular bone density in modern humans [PDF]

open access: yes, 2014
Humans are unique, compared with our closest living relatives (chimpanzees) and early fossil hominins, in having an enlarged body size and lower limb joint surfaces in combination with a relatively gracile skeleton (i.e., lower bone mass for our body ...

3D Digitization and Prototyping of the Skull for Practical Use in the Teaching of Human Anatomy

open access: yesJournal of medical systems, 2017
The creation of new rapid prototyping techniques, low cost 3D printers as well as the creation of new software for these techniques have allowed the creation of 3D models of bones making their application possible in the field of teaching anatomy in the ...
