Background: Alzheimer’s disease (AD) is an increasingly prevalent neurodegenerative characterized by protein aggregation in the form of amyloid plaques containing beta-amyloid peptides and neurofibrillary tangles hyperphosphorylated tau protein. The central molecular events underlying AD pathogenesis remain controversial poorly defined. Drosophila melanogaster has emerged as important genetic r...

Background: Flubendiamide, comparatively a new pesticide designed to eradicate lepidopteran insect pests is known to have low risk to birds, mammals, fish, algae, honey bees, non-target arthropods, earthworms, soil macro- and micro-organisms, non-target plants as well as sewage treatment organisms; however, the risk assessment for aquatic invertebrates from metabolite could not be finalized wit...

HIGHLIGHTS The longevity of the female and male Drosophila melanogaster is improved at doses given Aloe vera. Trifluralin has been observed to cause DNA damage, while vera shown reduce damage. reduced larval survival rate, increased rate high concentration.

Transdifferentiation is a conversion of an already differentiated cell type into another without the involvement stem cells. This transition well described in case vertebrate immune cells, as Drosophila melanogaster, which therefore serves suitable model to study process detail. In larva, latest single-cell sequencing methods enabled clusterization phagocytic blood plasmatocytes, are capable tr...

The widespread use of triazoles in agriculture as retardants has led to the need investigate possible mutagenic effects these compounds on natural ecosystems adjacent agrocoenoses. Model experiments were set up ability induce dominant lethal mutations by synthesized triazoles: 1,2,4-triazole: (1,2,4-triazole (1,2,4-TrH), N-triazolid methanesulfonic acid (CH₃SO₂TrH), benzene sulfonic (PhSO₂1,2,4...

Since its inception in 1929, Cytologia has made several significant contributions to the international community, including supporting various discoveries Drosophila. These experiments were not only successful D. melanogaster but also other species, such as virilis and ananassae. This is because two founding Fly Rooms Japan, one at Kyoto University Tokyo Metropolitan University, included these ...

A simple method to distinguish hitchhiking and background selection is proposed. It is based on the observation that these models make different predictions about the average level of nucleotide diversity in regions of low recombination. The method is applied to data from Drosophila melanogaster and two highly selfing tomato species.

Abstract Chemotaxis, the biased movement of cells in response to chemical gradients, plays an important role coordinating cell migration many biological phenomena (see Hillen and Painter 2009). For example, fruit fly Drosophila melanogaster navigates up gradients attractive odors during food location, male moths follow pheromone released by female mate location.
