Traumatic brain injury
Nervenarzt. 2023 Sep 7. doi: 10.1007/s00115-023-01546-9. Online ahead of print.ABSTRACTTraumatic brain injury (TBI) describes parenchymal brain damage caused by external forces to the head. It has a massive personal and socioeconomic impact, as it is a disease with high morbidity and mortality. Both young and old people are affected, as a result of traffic or sports accidents as well as due to falls at home. The term TBI encompasses various clinical pictures, differing considerably in cause, prognosis and therapy. What they all have in common is the pathophysiological cascade that develops immediately after the initial tra...

A cross-comparative analysis of in vivo versus ex vivo MRI indices in a mouse model of concussion
CONCLUSION: Our findings call for caution in extrapolating translational capabilities obtained ex vivo to physiological measurements in vivo. The divergent findings may reflect fixation artefacts and the contribution of the glymphatic system changes.PMID:37673379 | DOI:10.1016/j.brainres.2023.148562

Functional assessment in endometrial and cervical cancer: diffusion and perfusion, two captivating tools for radiologists
Eur Rev Med Pharmacol Sci. 2023 Aug;27(16):7793-7810. doi: 10.26355/eurrev_202308_33435.ABSTRACTUterine cervical and endometrial cancers are two major gynecological malignancies, affecting women's health worldwide. Magnetic resonance imaging (MRI) is appropriate for evaluating malignant disease, thanks to the excellent soft tissue contrast and multiplanar imaging ability. Recently, functional MR techniques, namely diffusion-weighted imaging (DWI) and dynamic contrast-enhanced imaging (DCE), have proved to be a precious support not only in cancer diagnosis but also in disease staging, in the therapy planning, in monitoring ...

Contrast-agent-based perfusion MRI code repository and testing framework: ISMRM Open Science Initiative for Perfusion Imaging (OSIPI)
CONCLUSIONS: The OSIPI DCE-DSC code repository represents a novel community-led model for code sharing and testing. The repository facilitates the re-use of existing code and the benchmarking of new code, promoting enhanced reproducibility in quantitative perfusion imaging.PMID:37667526 | DOI:10.1002/mrm.29826

Laws of taxation for multicellular organisms: The economics of sleep
Biosystems. 2023 Sep 2:105018. doi: 10.1016/j.biosystems.2023.105018. Online ahead of print.ABSTRACTIn macro-public finance, the Ramsey rule (RR) concerns variable taxation to maximize social welfare and economic efficiency in a purely competitive monopolistic system. To extract tax revenue with the least loss of utility to the representative individual, RR dictates that optimal, proportionate taxes should be such as to diminish in the same proportion the production of each commodity taxed. The sources of supply that are inelastic, i.e., necessities/utilities, must be taxed more. We hypothesize that the Ramsey's economical...

Investigating cerebral perfusion with high resolution hyperpolarized 1- < sup > 13 < /sup > Cpyruvate MRI
CONCLUSION: Acquiring HP 13 C pyruvate metabolic images at higher resolution allows for finer spatial delineation of brain structures and can be used to obtain cerebral perfusion parameters. Pyruvate perfusion parameters were positively correlated to proton ASL perfusion values, indicating a relationship between the two perfusion measures. This HP 13 C study demonstrated that hyperpolarized pyruvate MRI can assess cerebral metabolism and perfusion within the same study.PMID:37665726 | DOI:10.1002/mrm.29844

Niche-specific macrophage loss promotes skin capillary aging
bioRxiv. 2023 Aug 27:2023.08.25.554832. doi: 10.1101/2023.08.25.554832. Preprint.ABSTRACTAll mammalian organs depend upon resident macrophage populations to coordinate repair processes and facilitate tissue-specific functions 1-3 . Recent work has established that functionally distinct macrophage populations reside in discrete tissue niches and are replenished through some combination of local proliferation and monocyte recruitment 4,5 . Moreover, decline in macrophage abundance and function in tissues has been shown to contribute to many age-associated pathologies, such as atherosclerosis, cancer, and neurodegeneration 6-...
