Titin Is Present in the Elastic Tethers That Connect Separating Anaphase Chromosomes in Crane‐Fly Spermatocytes

open access: yesCytoskeleton, EarlyView.
ABSTRACT Elastic tethers connect telomeres of separating chromosomes in anaphase of animal cells. Immunofluorescence staining of titin in crane‐fly spermatocytes, using 4 different antibodies, shows that the giant elastic protein titin seems to be a component of mitotic tethers: titin “strands” extend between separating chromosomes, connecting their ...

Characterization of a broad-based mosquito yeast interfering RNA larvicide with a conserved target site in mosquito semaphorin-1a genes [PDF]

open access: yes, 2019
BACKGROUND: RNA interference (RNAi), which has facilitated functional characterization of mosquito neural development genes such as the axon guidance regulator semaphorin-1a (sema1a), could one day be applied as a new means of vector control ...

Beyond birds: rethinking bird‐centered pathogen models in light of insect migration

open access: yesEcography, EarlyView.
Migration redistributes biomass, nutrients, and pathogens across ecosystems. For decades, migratory birds have been treated as the default long‐distance pathogen vectors, shaping both conceptual frameworks and empirical models of disease ecology.

Mapping of Aedes albopictus abundance at a local scale in Italy [PDF]

open access: yes, 2017
Given the growing risk of arbovirus outbreaks in Europe, there is a clear need to better describe the distribution of invasive mosquito species such as Aedes albopictus. Current challenges consist in simulating Ae. albopictus abundance, rather than its

Antioxidant and Cytotoxic Properties of Piper spp. Volatile Oils That Inhibit Pathogenic Microorganisms

open access: yesFlavour and Fragrance Journal, EarlyView.
The samples were fungicidal against Candida, with MICs ranging from 62.5 to 250 μg/mL, and fungistatic against Penicillium adametzii, Aspergillus flavus and A. niger, with MICs of 1000 μg/mL. The volatile oils of Piper aduncum and Piper marginatum reduced the viability of MDA‐MB231 cells.

Current resistance status of Aedes aegypti and Aedes albopictus populations in Penang Island, Malaysia

open access: yesAsian Pacific Journal of Tropical Medicine
Objective: To determine the current insecticide resistance status of Aedes (Ae.) aegypti and Ae. albopictus to four insecticides, namely 0.05% deltamethrin, 0.75% permethrin, 5% malathion and 0.25% pirimiphos–methyl using the World Health Organisation ...

Beyond Tradition: An Integrated Toxicological, Ecological, and Public Health Perspective on Aristolochic Acids

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Aristolochia species have long been used in traditional medicine for their presumed anti‐inflammatory, analgesic and antimicrobial properties. However, extensive toxicological and epidemiological evidence now demonstrates that these plants contain aristolochic acids (AAs) I and II, highly potent nephrotoxic, genotoxic, and carcinogenic ...
