Fragmentation pathways of nanofractal structures on surfaces [PDF]

open access: yesPhysical Review B, 2011
We present a detailed systematical theoretical analysis of the post-growth processes occurring in nanofractals grown on surface. For this study we developed a method which accounts for the internal dynamics of particles in a fractal. We demonstrate that particle diffusion and detachment controls the shape of the emerging stable islands on surface.

Staurosporine induces necroptotic cell death under caspase-compromised conditions in U937 cells [PDF]

open access: yes, 2012
For a long time necrosis was thought to be an uncontrolled process but evidences recently have revealed that necrosis can also occur in a regulated manner.

Femtosecond real-time probing of reactions. XI. The elementary OClO fragmentation [PDF]

open access: yes, 1993
Femtosecond reaction dynamics of OClO in a supersonic molecular beam are reported. The system is excited to the A 2A2 state with a femtosecond pulse, covering a range of excitation in the symmetric stretch between v1=17 to v1=11 (308–352 nm).

Proteolytic Processing of OPA1 Links Mitochondrial Dysfunction to Alterations in Mitochondrial Morphology [PDF]

open access: yes, 2006
Many muscular and neurological disorders are associated with mitochondrial dysfunction and are often accompanied by changes in mitochondrial morphology.

Identification of Iridoids in Edible Honeysuckle Berries (Lonicera caerulea L. var. kamtschatica Sevast.) by UPLC-ESI-qTOF-MS/MS

open access: yesMolecules, 2016
Iridoid profiles of honeysuckle berry were studied. Compounds were identified by ultra-performance liquid chromatography coupled with electrospray ionization mass spectrometry UPLC-ESI-qTOF-MS/MS in positive and negative ions mode.

Drp1‐dependent peptide reverse mitochondrial fragmentation, a homeostatic response in Friedreich ataxia

open access: yesPharmacology Research & Perspectives, 2021
Friedreich ataxia is an autosomal recessive, neurodegenerative disease characterized by the deficiency of the iron‐sulfur cluster assembly protein frataxin. Loss of this protein impairs mitochondrial function.

Growth dynamics and the evolution of cooperation in microbial populations [PDF]

open access: yes, 2012
Microbes providing public goods are widespread in nature despite running the risk of being exploited by free-riders. However, the precise ecological factors supporting cooperation are still puzzling.

Minimal Folding Pathways for Coarse-Grained Biopolymer Fragments [PDF]

open access: yesBiophysical Journal, 2008
The minimal folding pathway or trajectory for a biopolymer can be defined as the transformation that minimizes the total distance traveled between a folded and an unfolded structure. This involves generalizing the usual Euclidean distance from points to one-dimensional objects such as a polymer.

Structure-based identification and pathway elucidation of flavonoids in Camptotheca acuminate

open access: yesSynthetic and Systems Biotechnology, 2022
Flavonoid metabolism in Camptotheca acuminate remained an untapped area for years. A tandem MS approach was used and focused on the mining and characterizing of flavonoids in mature C. acuminate.

Saturated free fatty acids and apoptosis in microvascular mesangial cells: palmitate activates pro-apoptotic signaling involving caspase 9 and mitochondrial release of endonuclease G [PDF]

open access: yes, 2005
BACKGROUND: In type 2 diabetes, free fatty acids (FFA) accumulate in microvascular cells, but the phenotypic consequences of FFA accumulation in the microvasculature are incompletely understood. Here we investigated whether saturated FFA induce apoptosis
