Nanoparticles Functionalized with Polymer Brushes for Gene Delivery

open access: yesAdvanced NanoBiomed Research, EarlyView.
The engineering of the next generation gene delivery vectors requires the precise control of the architecture and physicochemical interactions controlling the transport, targeting, uptake, and release of nucleic acid materials to targeted cells. Polymer brush‐functionalized nanomaterials offer unprecedented control over such design and properties, and ...

Cloning and expression of the Propionibacterium shermanii methylmalonyl-CoA epimerase gene in Escherichia coli : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Biochemistry at Massey University [PDF]

open access: yes, 1994
Genomic DNA was isolated from Propionibacterium shermanii (52W). A 454 bp DNA fragment coding for the methylmalonyl-CoA epimerase (EC 5.1.99.1, subsequently referred to as epimerase) was amplified from genomic DNA by the polymerase chain reaction using ...

Inter‐Nanoparticle FRET for Biosensing: Photophysics Versus Size

open access: yesAngewandte Chemie International Edition, EarlyView.
Förster resonance energy transfer (FRET) systems with luminescent nanoparticles (NPs) as donors and acceptors (inter‐NP FRET) combine unique photophysical properties with large sizes. This review discusses the influence of NP type, architecture, surface chemistry, and optical properties on FRET and the pros and cons of inter‐NP FRET for bioanalytical ...

Ethnomedicinal Uses, Phytochemistry, Pharmacological Activities, and Toxicology of the Subfamily Gomphrenoideae (Amaranthaceae): A Comprehensive Review

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT The subfamily Gomphrenoideae is composed of about 480 accepted species, many of which have been historically used as medicinal plants, reason why they have been studied in terms of chemical profile, biological activity, and safety. This review consolidates the advances in research on this subfamily over the past 47 years, emphasizing its ...

Propentofylline reduces glial scar development following gliotoxic damage in the rat brainstem

open access: yesArquivos de Neuro-Psiquiatria
Propentofylline is a xanthine derivative that depresses activation of glial cells, whose responses contribute to neural tissue damage during inflammation.
