Impact of Environmental Microparticles on Insect Olfaction

Environmental Toxicology, EarlyView.
ABSTRACT Terrestrial insects underpin key ecosystem services, including pollination, herbivory regulation, decomposition, nutrient cycling, and disease control. These functions depend on chemical communication that guides insects to food, mates, hosts, shelters, and oviposition sites while helping them avoid threats.

Increased PAI-1 plasma levels and risk of death from dengue: no association with the 4G/5G promoter polymorphism [PDF]

, 2005
Background: Dengue virus infected patients have high plasminogen activator inhibitor type I (PAI-1) plasma concentrations. Whether the insertion/deletion (4G/5G) polymorphism in the promotor region of the PAI-1 gene is associated with increased PAI-1 ...

Key Amino Acid Substitution for Infection-Enhancing Activity-Free Designer Dengue Vaccines

iScience, 2019
Summary: Dengue is a globally important disease caused by four serotypes of dengue virus. Dengue vaccine development has been hampered by antigenic cross-reactivity among serotypes, which potentially causes antibody-dependent enhancement of infection and

Two‐Dimensional Materials For Lateral Flow Assays: A Critical Review of Functional Roles and Translational Challenges

VIEW, EarlyView.
2D nanosheets, with large surface area, excellent optical/electrical properties, and high specificity, combine with lateral flow assay strips to enable rapid, readable detection, boosting the strips’ development and applications. Abstract Lateral flow assays (LFAs) are widely used for point‐of‐care diagnostics, but their detection capability remains ...

Maltase 1 regulates DENV2 infection and life history in Aedes aegypti

Insect Science, EarlyView.
Our study employed CRISPR/Cas9 to generate a MAL1 knockout strain of Aedes aegypti, demonstrating that the absence of MAL1 significantly suppresses DENV2 replication in the midgut and impairs viral transmission. The mutation also altered life‐history (hatching/pupation/emerging rates and sex‐specific survival), identifying MAL1 as a novel target for ...

Risk Factors for Mortality in Dengue Shock Syndrome (DSS) [PDF]

, 2009
Background: Dengue shock syndrome (DSS) is the most severe form of dengue hemorrhagic fever (DHF) and has a high mortality. There are two major pathological changes in DHF determining the severity of disease, plasma leakage and bleeding.

Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.
