Characterizing neuromorphologic alterations with additive shape functionals

open access: yes, 2004
The complexity of a neuronal cell shape is known to be related to its function. Specifically, among other indicators, a decreased complexity in the dendritic trees of cortical pyramidal neurons has been associated with mental retardation.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Study on the performance of nanoparticle-modified PVDF membrane in delaying membrane aging

open access: yesOpen Chemistry
With an emphasis on improving the membrane’s long-term durability and filtering efficiency, this study examines how well nanoparticle-modified polyvinylidene fluoride (PVDF) membranes perform in postponing membrane aging.

Ultrasmall volume Plasmons - yet with complete retardation effects

open access: yes, 2008
Nano particle-plasmons are attributed to quasi-static oscillation with no wave propagation due to their subwavelength size. However, when located within a band-gap medium (even in air if the particle is small enough), the particle interfaces are acting ...

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Branched-chain and odd-numbered fatty acids and aldehydes in the nervous system of a patient with deranged vitamin B12 metabolism

open access: yesJournal of Lipid Research, 1973
A mixture of isomers of methylhexadecanoic acid was isolated from glycerolipids of brain, spinal cord, and sciatic nerve of a patient who died from methylmalonic aciduria, a disease in which vitamin B12 is not converted to deoxyadenosyl B12.

β‐TrCP overexpression enhances cisplatin sensitivity by depleting BRCA1

open access: yesMolecular Oncology, EarlyView.
Low levels of β‐TrCP (Panel A) allow the accumulation of BRCA1 and CtIP, which facilitate the repair of cisplatin‐induced DNA damage via homologous recombination (HR) and promote tumor cell survival. In contrast, high β‐TrCP expression (Panel B) leads to BRCA1 and CtIP degradation, impairing HR repair, resulting in persistent DNA damage and apoptosis ...

Quantitative analysis of brain galactosylceramides by high performance liquid chromatography of their perbenzoyl derivatives

open access: yesJournal of Lipid Research, 1976
A high performance liquid chromatographic (HPLC) method for analysis of galactosylceramides as their benzoyl derivatives has been devised. Samples containing 10-150 nmoles of monohexosylceramides are benzoylated by heating for 60 min at 60 ° C in 0.5 ml ...
