Edith Cowan University, Perth, Western Australia, Australia.
Background: Accumulation of amyloid beta 42 (Aβ42) senile plaques is the most critical event leading to Alzheimer's disease (AD). Currently approved drugs for AD have not been able to effectively modify the disease. This has caused increasing research interests in health beneficial nutritious plant foods as viable alternative therapy to prevent or manage AD.

Alzheimers Dement
December 2024
Federal University of Technology, Akure, Ondo, Nigeria.
Background: In recent decades, epidemiological and experimental studies have looked into the role of pesticides, particularly the herbicide paraquat, in the development of Parkinson's disease. Horseradish tree (Moringa oleifera) is an ethnobotanical plant with lots of therapeutic potential, but there is a dearth of information on the bioactive properties of the seed alkaloid extracts.
Method: This study examined the modulatory effects of various concentrations of an alkaloid extract from the seeds of Horseradish Tree (Moringa oleifera) on the survival rate of flies exposed to paraquat, as well as certain biochemical and molecular markers related to Parkinson's disease in the heads of the flies.

The light-harvesting pigment-protein complex II (LHCII) from plants can be used as a component for biohybrid photovoltaic devices, acting as a photosensitizer to increase the photocurrent generated when devices are illuminated with sunlight. LHCII is effective at photon absorption in the red and blue regions of the visible spectrum, however, it has low absorption in the green region (550-650 nm). Previous studies have shown that synthetic chromophores can be used to fill this spectral gap and transfer additional energy to LHCII, but it was uncertain whether this would translate into an improved performance for photovoltaics.

Alzheimers Dement
December 2024
Samford University McWhorter School of Pharmacy, Birmingham, AL, USA.
Background: Despite some advances in treatment, a cure for Alzheimer's disease (AD) remains elusive. Disease hallmarks include heightened neuroinflammation and oxidative stress, associated with progressive decline in mobility and cognitive functions. Natural compounds provide a valuable reservoir of novel bioactive substances with therapeutic potential, fewer side effects, and increased affordability.
