A natural barrier: tick‐repellent potential of a spruce‐derived volatile blend against Hyalomma excavatum and Ixodes ricinus

Pest Management Science, EarlyView.
Both active and passive questing ticks, Hyalomma excavatum and Ixodes ricinus, were assessed for behavioural responses to two novel plant‐derived repellent volatile organic compound blends. Both tick species were repelled by the products, and both novo blends were significantly more repellent than currently available commercial products.

Bioengineered Extracellular Vesicles in Emerging Cancer Vaccine Platforms

Small Science, EarlyView.
This review highlights recent advances in engineering extracellular vesicles (EVs) as next‐generation cancer vaccines. It outlines their biological roles and antigen‐presenting capacity, explores key strategies for antigen loading and delivery optimization, and summarizes preclinical and clinical applications using EVs from diverse immune and tumor ...

Ecotoxicological Evaluation of Organic Sunscreens Used Worldwide, Alone and in Mixture, on Terrestrial Plants

Environmental Toxicology, EarlyView.
ABSTRACT The environmental hazards of sunscreens are discussed worldwide. However, there are few ecotoxicological studies on these compounds alone for edaphic organisms, and none for their mixtures. Avobenzone (1 and 10 ng/L), octocrylene (10 and 100 μg/L), and oxybenzone (2 and 20 μg/L), alone and in binary combinations (between the lowest and the ...

Conceptualization of Health Nationalism and Glocalization of Health Policy: Barriers and Chances for Global Public Health

World Medical &Health Policy, EarlyView.
ABSTRACT This article aims to sort out the meaning of the term “health nationalism,” operationalize this term and analyze this phenomenon in opposition to the cosmopolitan health policy model. Here, health nationalism is treated as a serious obstacle to access to healthcare and a cultural‐ideological barrier to equity in global public health. Two ideal

"Rejuvenescence in protozoa" [PDF]

Experimental Biology and Medicine, 1904
The process of conjugation in protozoa involves either temporary or permanent union of two individuals. During this union there is a fusion of nuclear material from both organisms resulting in the formation of new cleavage nuclei in each exconjugant. The process is directly comparable with fertilization of an egg by a spermatozoon, and the biological ...

Taxonomic, phylogenetic and functional β‐diversity of stream algae is driven by the number of added nutrients and herbivory

Journal of Ecology, EarlyView.
Higher numbers of added nutrients (NAN) in treatment (T) relative to control (C) algal communities (1) and grazing (2) elevated taxonomic/phylogenetic nestedness (βNes) and functional gradient (βGra) components of β‐diversity. Herbivory favoured grazer‐resistant inferior competitors (2).

Evaluation of two candidate molecules—TCTP and cecropin—on the establishment of Trypanosoma brucei gambiense into the gut of Glossina palpalis gambiensis

Insect Science, EarlyView.
This study investigates the potential of enhancing the resistance of Glossina palpalis gambiensis to Trypanosoma brucei gambiense to mitigate the transmission of Human African Trypanosomiasis. We successfully cloned genes encoding proteins of interest in Sodalis strains, resulting in recombinant Sodalis (recSodalis) that were micro‐injected into the L3
