Photodegradation of commercial insect repellents containing DEET and IR‐3535 under ultraviolet light associated or not with chemical ultraviolet filters evaluated by Raman spectroscopy

open access: yesPhotochemistry and Photobiology, EarlyView.
This study evaluated the photodegradation of commercial insect repellents containing DEET and IR‐3535 under UV‐A and UV‐B irradiation using Raman spectroscopy. Pure DEET and IR‐3535 showed intrinsic photostability, whereas DEET diluted in ethanol and a commercial DEET‐based formulation exhibited significant spectral changes after UV exposure.

The Comparative Effectiveness of Vector Control Approaches for Dengue: A Systematic Review and Multilevel Network Meta‐Analysis

open access: yesTropical Medicine &International Health, EarlyView.
ABSTRACT Background Dengue vector control plays an important role in reducing the burden of dengue infection. Conventional meta‐analysis can only include interventions that can be directly compared. Hence, this study aimed to compare the effectiveness of all interventions for dengue vector control directly and indirectly through a multilevel Bayesian ...

Virus‐specific alterations in placental structure and transporter expression following maternal arbovirus infection

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Arboviruses induce virus‐specific alterations in placental structure and functional markers. Chikungunya virus (CHIKV) exposure was associated with reduced syncytiotrophoblast and syncytial knot areas, increased cytotrophoblast proliferation (Ki‐67) and thyroid transporter (MCT8) expression, reduced protective (P‐gp and BCRP ...

Garlic‐Derived Behavioural Deterrents: Diallyl Disulfide and TrpA1‐Mediated Suppression of Insect Reproduction

open access: yesModern Agriculture, Volume 4, Issue 2, December 2026.
Garlic‐derived diallyl disulfide acts as a behavioural deterrent that suppresses insect mating and oviposition through sensory pathways. The compound is detected through gustatory mechanisms involving the transient receptor potential A1 (TrpA1) channel and neural responses.

Burden of Dengue and Chikungunya – A Retrospective Study

open access: yes, 2021
Arboviral infections like dengue fever and chikungunya are the most common infections that share the same Aedes mosquito vectors. Clinical presentations of these two infections are also similar, especially in initial stages.

UHPLC‐DAD‐HRMS2 Characterization of Novel Dihydrochalcone Conjugates From the Antiviral Mansoa hirsuta Extracts: Diagnostic Fragmentation Pathways and Dereplication of Oligomeric Polyphenols

open access: yesJournal of Mass Spectrometry, Volume 61, Issue 11, November 2026.
ABSTRACT High‐resolution mass spectrometry (HRMS) coupled with ultra‐high‐performance liquid chromatography (UHPLC) enables rapid characterization of complex polyphenolic constituents in medicinal plants. Mansoa hirsuta (Bignoniaceae), a neotropical liana traditionally used to treat infectious diseases, remains poorly characterized chemically.
