Ciekawostka: Chocolate can kill dogs; it directly affects their heart and nervous system

Evidence: 73 • authority: 72

Theobromine, also known as xantheose, is the principal alkaloid of Theobroma cacao (cacao plant). Theobromine is slightly water-soluble (330 mg/L) with a bitter taste. In industry, theobromine is used as an additive and precursor to some cosmetics. It is found in chocolate and several other foods, including tea (Camellia sinensis), some American hollies (yaupon and guayusa) and the kola nut. It is a white or colourless solid, but commercial samples can appear yellowish. Theobromine, a metabolite of caffeine, is processed in the liver into xanthine and methyluric acid, peaks in the blood 2–3 hours after ingestion due to its fat solubility, and primarily acts by inhibiting adenosine receptors…

Does Pulmonary Function Testing Affect Autonomic Nervous System Activity?. Abstract Background The autonomic nervous system (ANS) regulates vital functions such as heart rate and respiration. Pulmonary function tests (PFT) involve forced breathing maneuvers that may influence ANS activity. However, the extent of this interaction remains unclear. Understanding this relationship is important for ensuring accurate autonomic measurements during clinical assessments. This study aims to investigate the effects of pulmonary function tests on the ANS and scientifically determine the interaction between these two systems and the accuracy of the test order. Methods The study was conducted with 48 vol…
