Neuroprotective Effect of Nigella sativa Essential Oil against Experimental Demyelination through Regulation of Endogenous Fatty Acid Levels in Rat Spinal Cord Tissue

open access: yesJournal of Mazandaran University of Medical Sciences, 2022
Background and purpose: Myelin degradation is one of the main causes of some neurological diseases. There is growing evidence that plant essential oils may reduce the risk of demyelination.

Synthetic polymer nanocarrier enhances dsRNA stability but not RNAi efficacy in Brassicogethes aeneus

open access: yesPest Management Science, EarlyView.
Experimental setup for dsRNA feeding in Brassicogethes aeneus to evaluate the effect of a synthetic polymer nanocarrier on RNAi efficiency. The experiment assessed whether the nanocarrier enhances RNAi after oral dsRNA delivery. (a) Stability of dsRNA–nanocarrier complexes was tested in simulated gut conditions. (b) Gene expression of αCOP and dre4 was

2D van der Waals System Integrated with Targeting Radio‐Diagnostic and Imaging Functions

open access: yesSmall, EarlyView.
Layered double hydroxide (LDH) nanoplates were engineered for tumor‐targeted imaging and therapy. By exploiting folate receptor (FR) expression levels, the system achieves selective tumor accumulation and high‐resolution dual PET/fluorescence (PET/FL) imaging.

In Situ Assessment of Cell Viability

open access: yesCell Transplantation, 1998
Cryobiologlcal studies of tissues often require the simultaneous assessment of tissue structure and in situ cellular function. Localization of damage during cryopreservation occurs as a consequence of tissue structure and morphology and as a result of ...

Mechanosensitive Cell‐Laden Shape‐Memory Scaffolds Engineered via Cryogelation

open access: yesSmall Structures, EarlyView.
GelMA‐based shape‐memory scaffolds encapsulating human adipose‐derived stem cells are fabricated via cryogelation, showing rapid recovery and high cell viability. Under cyclic compression, they promoted mechanotransduction gene expression, and composite formulations (collagen/GelMA, dECM/GelMA) retained robust shape‐memory, highlighting their promise ...

‘Candidatus Phytoplasma solani’: From infection to all‐round characterisation of distinct tuf‐type strains with different virulence in tomato plants

open access: yesAnnals of Applied Biology, EarlyView.
‘Candidatus Phytoplasma (Ca. P.) solani’ is associated with bois noir (BN) of grapevine and stolbur of solanaceous plants and is primarily transmitted by Hyalesthes obsoletus Signoret. Four tuf‐a and five tuf‐b1 ‘Ca. P. solani’ strains were transmitted to tomato plants (cv. Micro‐Tom) by using bait‐plants and by capturing H.

Ethidium bromide-induced demyelination of the sciatic nerve of adult Wistar rats

open access: yesBrazilian Journal of Medical and Biological Research, 2002
Peripheral nerve ultrastructure was assessed after single or multiple local injections of the intercalating dye ethidium bromide. Thirty-four adult Wistar rats of both sexes were divided into five groups and maintained in a controlled environment with ...

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 ...
