Reverse chemical ecology indicates long-chain aldehydes as new potential semiochemicals for the African elephant Loxodonta africana

Frontiers in Ecology and Evolution, 2022
Chemical communication between sexes in the elephants has been well studied at the chemical and behavioural levels, but little is known about the proteins mediating the exchange of chemical signals.

A guide to reactive oxygen species in tumour hypoxia: measurement and therapeutic implications

Molecular Oncology, EarlyView.
Hypoxia reshapes tumour redox landscapes by altering compartmental ROS production (mitochondria, NOX, ER, peroxisomes). Accurate interpretation requires oxygen‐contextualised measurement (live biosensors, chemical probes, EPR, LC–MS) and awareness of artefacts (reoxygenation, probe specificity).

Pathological In Vivo Analysis of Helicobacter DNA Infection in Stomach Cells Using Carbon Nanotube Microsensor

Microorganisms
The WHO has classified Helicobacter pylori as a group 1 carcinogen for stomach cancer since early 1994. However, despite the high prevalence of Helicobacter pylori infection, only about 3% of infected people eventually develop gastric cancer.Biomolecular

Hydrogel‐Based Capacitive Sensor Model for Ammonium Monitoring in Aquaculture

Advanced Engineering Materials, EarlyView.
Traditional techniques for monitoring aquaculture water quality, particularly ammonium levels, harm fish. This work presents a novel capacitive sensor with an ionic hydrogel transducer to monitor ammonium concentration in real time based on the ammonium‐induced hydrogel dissociation and osmotic pressure. Monitoring aquaculture water quality, especially
