Prophylaxis by a reversible cholinesterase inhibitor and the treatment NMDA receptor antagonists as combinatorial countermeasure against nerve agent poisoning in mice model.

The current pharmacological pretreatment and medical treatment of nerve agent poisoning is an insufficiently addressed medical task. The prophylactic efficacy of a novel compound acting dually as an acetylcholinesterase inhibitor and NMDA receptor antagonist (K1959) and the therapeutic efficacy of a novel NMDA receptor antagonist (K2060) were evaluated in the NMRI mice model of nerve agent poisoning by tabun, soman and sarin. Their added value to the standard antidotal treatment (a combination of oxime reactivator and atropine) was also analyzed.

Ortner's syndrome in interdisciplinary collaboration.

Ortner's syndrome, also known as cardiovocal syndrome, is a rare cause of hoarseness due to compression of the left recurrent laryngeal nerve caused by pathology of cardiovascular structures in the mediastinum. It was first described by Norbert Ortner in 1897, who associated the syndrome with mitral stenosis. It typically presents as paresis of the left recurrent laryngeal nerve, which is mechanically compressed in the area of the aortic arch.

Powering Agriculture IoT Sensors Using Natural Temperature Differences Between Air and Soil: Measurement and Evaluation.

As the need to monitor agriculture parameters intensifies, the development of new sensor nodes for data collection is crucial. These sensor types naturally require power for operation, but conventional battery-based power solutions have certain limitations. This study investigates the potential of harnessing the natural temperature gradient between soil and air to power wireless sensor nodes deployed in environments such as agricultural areas or remote off-grid locations where the use of batteries as a power source is impractical.

Dizocilpine derivatives as neuroprotective NMDA receptor antagonists without psychomimetic side effects.

We aimed to prepare novel dibenzo [a,d][7]annulen derivatives that act on N-methyl-d-aspartate (NMDA) receptors with potential neuroprotective effects. Our approach involved modifying the tropane moiety of MK-801, a potent open-channel blocker known for its psychomimetic side effects, by introducing a seven-membered ring with substituted base moieties specifically to alleviate these undesirable effects. Our in silico analyses showed that these derivatives should have high gastrointestinal absorption and cross the blood-brain barrier (BBB).
