Volabolomic Fingerprinting for Post-Mortem Interval Estimation: A Novel Physiological Approach.

Death is a multifaceted process wherein each individual cell and tissue has a metabolic homeostasis and a time of functional cessation defined by the dying process as well as by intrinsic and extrinsic factors. Decomposition is physiologically associated with the release of different types of volatile organic compounds (VOCs), and these form volaboloma mortis. The main purpose of this study was to record the volabolomic fingerprint produced by volatile molecules during the physiological decomposition process of human tissue and muscle cells.

Aging and the carotid body: A scoping review.

The carotid body (CB) is a neuroepithelial tissue consisting of O-sensitive glomus cells that constantly scan the arterial blood for O and generate a discharge as an inverse function of O content. Aging is a cumulative result of decreased O supply paralleled by a decreased O tissue demand and oxidative damage to cells derived from aerobic metabolism. Here we studied how CB affects the aging process.

The Evanescent Bouquet of Individual Bear Fingerprint.

The evanescent and invisible communication carried by chemical signals, pheromones, or signature mixtures or, as we prefer, the pheromonal individual fingerprint, between members of the same species is poorly studied in mammals, mainly because of the lack of identification of the molecules. The difference between pheromones and the pheromonal individual fingerprint is that the former generate stereotyped innate responses while the latter requires learning, i.e.

Physiological discrimination and correlation between olfactory and gustatory dysfunction in long-term COVID-19.

The spread of the SARS-CoV-2 virus produces a new disease termed COVID-19, the underlying physiological mechanisms of which are still being understood. Characteristic of the infection is the compromising of taste and smell. There is a persistent need to discriminate the dysfunctions and correlation between taste and smell, which are probably epiphenomena of other concealed conditions.
