Targeted Isolation of Neuroprotective Dicoumaroyl Neolignans and Lignans from Sageretia theezans Using in Silico Molecular Network Annotation Propagation-Based Dereplication.

open access: yesJournal of Natural Products, 2018
The integration of LC-MS/MS molecular networking and in silico MS/MS fragmentation is an emerging method for dereplication of natural products. In the present study, a targeted isolation of natural products using a new in silico-based annotation tool ...

Networks in molecular evolution

open access: yesComplexity, 2002
Networks in molecular evolution properties of the RNA map were derived: "For sequence spaces of chain lengths n > 10 there are orders of magnitude more sequences than structures and hence, the map is many-to-one (as predicted analytically above)." "Few common and many rare structures." "In other words, for each arbitrarily chosen pair of structures ...

A stepwise emergence of evolution in the RNA world

open access: yesFEBS Letters, EarlyView.
How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

Graph Theory and Networks in Biology [PDF]

open access: yes, 2006
In this paper, we present a survey of the use of graph theoretical techniques in Biology. In particular, we discuss recent work on identifying and modelling the structure of bio-molecular networks, as well as the application of centrality measures to ...

LC-MS Based Phytochemical Profiling towards the Identification of Antioxidant Markers in Some Endemic Aloe Species from Mascarene Islands

open access: yesAntioxidants, 2022
Aloe plant species have been used for centuries in traditional medicine and are reported to be an important source of natural products. However, despite the large number of species within the Aloe genus, only a few have been investigated ...

Uncovering the molecular networks in periodontitis [PDF]

open access: yesPROTEOMICS – Clinical Applications, 2014
Periodontitis is a complex immune‐inflammatory disease that results from a preestablished infection in gingiva, mainly due to Gram‐negative bacteria that colonize deeper in gingival sulcus and latter periodontal pocket. Host inflammatory and immune responses have both protective and destructive roles.

B cell mechanobiology in health and disease: emerging techniques and insights into therapeutic responses

open access: yesFEBS Letters, EarlyView.
B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...

Network approach towards understanding the crazing in glassy amorphous polymers

open access: yes, 2017
We have used molecular dynamics to simulate an amorphous glassy polymer with long chains to study deformation mechanism of crazing and associated void statistics.

Designed-in molecular interactions lead to superior thermo-mechanical properties in nanocomposites [PDF]

open access: yes, 2011
The effect of the nanofiller chemistry on the mechanical behaviour of thermoset polymer matrix nanocomposites is investigated. The interaction between a crosslinked polymer resin and the reinforcing nanofibers driven by their chemistry is revealed by ...
