Introduction: Low-frequency electromagnetic field (50 Hz) (EMF) can modify crucial neuronal processes. Existing data indicate that exposure to EMF may represent a mild stressor and contribute to disturbances of hypothalamic-pituitary-adrenal (HPA) axis. The important regulatory pathways controlling HPA axis activity include two types of corticoste...

Studies reported evidence for opposite effects of extremely low-frequency electromagnetic field (EMF): harmful, including the oxidative stress induction, and beneficial, such as the activation of antioxidant defense. People’s exposure to EMF is often repeated or prolonged, and it is important to consider the cumulative effect of such kind of exposu...

Recovery of function after sensory nerves injury involves compensatory plasticity, which can be observed in invertebrates. The aim of the study was the evaluation of compensatory plasticity in the cockroach ( Periplaneta americana) nervous system after the sensory nerve injury and assessment of the effect of electromagnetic field exposure (EMF, 50...

Animal venoms are considered as a promising source of new drugs. Sea anemones release polypeptides that affect electrical activity of neurons of their prey. Voltage dependent sodium (Nav) channels are the common targets of Av1, Av2, and Av3 toxins from Anemonia viridis and CgNa from Condylactis gigantea. The toxins bind to the extracellular side of...

Great effort is put into seeking a new and effective strategies to control insect pests. One of them is to combine natural products with chemical insecticides to increase their effectiveness. In the study presented, menthol which is an essential oil component was evaluated on its ability to increase the efficiency of bendiocarb, carbamate insectici...

Voltage gated Na+ channels (Navs) are the target of a variety of natural neurotoxins, as they play a key role on in different organisms. Jaburetox (Jbtx) is a ~10 kDa entomotoxic peptide isolated from Jack Bean Urease (JBU) whose mechanism of action is elusive. Cockroaches are primitive animals suitable for neurobiological investigations due to the...
Article
Standard chemical insecticides present mainly neurotoxic effects and are becoming less and less effective due to insects developing resistance to them. One of the innovative strategies to control insects pests is to find a way to increase the sensitivity of the target sites in the insect nervous system to the applied insecticides. In the presented...

The aim of this work is to present the current knowledge about the possible participation of electromagnetic fields in the occurrence and also in treatment of neurodegenerative diseases. The literature data indicate both the negative and positive effects of electromagnetic fields and not allow to draw unambiguous conclusions. Undoubtedly, the topic...

Capsaicin is known to activate heat receptor TRPV1 and induce changes in thermoregulatory processes of mammals. However, the mechanism by which capsaicin induces thermoregulatory responses in invertebrates is unknown. Insect thermoreceptors belong to the TRP receptors family, and are known to be activated not only by temperature, but also by other...

Essential oils (EOs) are lipophilic secondary metabolites obtained from plants; terpenoids represent the main components of them. A lot of studies showed neurotoxic actions of EOs. In insects, they cause paralysis followed by death. This feature let us consider components of EOs as potential bioinsecticides. The inhibition of acetylcholinesterase (...

Background: Extremely low-frequency (50 Hz) electromagnetic field (ELF-EMF) is produced by electric power transmission lines and electronic devices of everyday use. Some phenomena are proposed as "first effects" of ELF-EMF: the discrete changes in the membrane potential and the increase of the calcium channel activity as well as the intracellular...

Owady–szkodniki powodują ogromne zniszczenia w uprawianych roślinach oraz przechowywanej żywności. Szacuje się, że około 14% strat w uprawach i 20% strat w przechowywanej żywności powodowanych jest przez owady. Straty te szacuje się na 100 miliardów dolarów każdego roku. Owady są również wektorami wielu groźnych chorób, np. malarii. Główną metodą w...
