N-alkylamides : from plant to brain [PDF]

, 2014
Background: Plant N-alkylamides (NAAs) are bio-active compounds with a broad functional spectrum. In order to reach their pharmacodynamic targets, they have to overcome several barriers of the body in the absorption phase.

Comprehensive Analysis of the Impact of Climate Change and Human Activities on the Distribution of Five Fritillaria Species Using the Optimized Maxent Model

Ecology and Evolution, Volume 15, Issue 10, October 2025.
This study utilized extensive specimen data and detailed geographic and environmental information, applying the Maxent model to predict the distribution of F. cirrhosae bulbus. The key findings are as follows: (1) F. przewalskii and F. delavayi tend to migrate to higher altitudes, while F. taipaiensis is shifting to lower altitudes. (2) Among different

Cloning and functional analysis of promoter of TcALDH and TcGLIP genes in Tanacetum cinerariifolium

Guangxi Zhiwu, 2023
Natural pyrethrin is a green botanical insecticide that extracted from the aboveground tissues of pyrethrum (Tanacetum cinerariifolium). Aldehyde dehydrogenase (TcALDH) and GDSL lipase (TcGLIP) are key rate-limiting enzymes involved in pyrethrin ...

Implications of genetic variation within pyrethrum (Chrysanthemum cinerariifolium and Chrysanthemum coccineum) germplasm: Intra‐ or inter‐specific hybridization as mechanisms to circumvent genetic bottlenecks

Crop Science, Volume 65, Issue 3, May/June 2025.
Abstract The University of Minnesota (UMN) Pyrethrum Breeding Program has been developing Chrysanthemum cinerariifolium with increased levels of Pyrethrin I/Pyrethrin II ratio (%Py) for over a decade. Pyrethrum is an economically important “green pesticide,” producing %Py in glandular trichomes, with the highest concentration in the flowers.

Pairing Residual Contact Insecticide Use With Long‐Lasting Insecticide‐Incorporated Netting to Reduce Dispersal and Damage by Stored Product Insects

Journal of Applied Entomology, Volume 149, Issue 4, Page 501-514, May 2025.
ABSTRACT Long‐lasting insecticide‐incorporated netting (LLIN) can intercept insects and has shown promise for pest management before and after harvest in agriculture. Understanding how to incorporate LLIN into existing integrated pest management (IPM) programs, with other commonly used tactics like residual contact insecticides, can significantly ...

Pyrethrins Protect Pyrethrum Leaves Against Attack by Western Flower Thrips, [PDF]

, 2012
Pyrethrins are active ingredients extracted from pyrethrum flowers (Tanacetum cinerariifolium), and are the most widely used botanical insecticide. However, several thrips species are commonly found on pyrethrum flowers in the field, and are the dominant

Genomic Analysis Reveals a New Cryptic Taxon Within the Anopheles gambiae Complex With a Distinct Insecticide Resistance Profile in the Coast of East Africa

Molecular Ecology, Volume 34, Issue 10, May 2025.
ABSTRACT Anopheles mosquitoes are major malaria vectors, encompassing several species complexes with diverse life histories, transmission risks and insecticide resistance profiles that challenge malaria control efforts. This study investigated the genetic structure and insecticide resistance profiles of Anopheles gambiae complex mosquitoes in Tanzania.

Effect of fire timing on the regeneration capacity of Helichrysum species in Tanzania

Ecological Solutions and Evidence, Volume 6, Issue 2, April–June 2025.
Shrub encroachment poses a significant challenge in many grassland ecosystems, particularly where disturbances such as heavy livestock grazing and uncontrolled fires are prevalent. The study investigated resprouting ability of Helichrysum shrubs after being completely, partially or not at all burned.
