Quantitative Morphological Study of Larynx APUD-Cells in Asphyxial Type of Drowning in Fresh Water (Experimental Study).

Article Synopsis
- A new microscopic diagnostic sign for asphyxial drowning has been discovered in white male rats, indicating changes in the laryngeal mucosa.
- The research showed significant hyperplasia (increase in the number of cells) of serotonin-containing APUD-cells in the larynx when rats experienced acute anoxia, compared to healthy controls.
- These changes may trigger laryngospasm, which helps prevent water from entering the airways during drowning, suggesting this hyperplasia can be a useful diagnostic criterion in research on drowning.

Since ancient times, the consumption of fermented low-alcoholic beverages has enjoyed widespread popularity in various countries, because of their distinct flavors and health benefits. Several studies have demonstrated that light to moderate alcohol consumption is associated with beneficial effects on human health, mainly in cardiovascular disease prevention. Fermented beverages have different non-ethanol components that confer beneficial health effects.

This study is an interdisciplinary research into Uruguayan ayahuasca users belonging to one neo-shamanic and one Santo Daime group. The study involved the chemical analysis of ayahuasca samples, an ethnographic description of the two traditions and rituals, and the application of psychometric scales to measure personality differences, and the acute psychological effects during an ayahuasca ritual. Personality measurements showed lower scores for Santo Daime in Neuroticism-Anxiety, Dependence, Low Self-Esteem, Anger and Restlessness.

The present research work aims to synthesize a blend of chitosan (CSN) and curcumin (CRN) based aqueous polyurethane dispersions (CSN-CRN APUDs) for the modification of textile surfaces. A series of anionic CSN-CRN APUDs were prepared by the reaction of isophorone diisocyanate (IPDI) with polyethylene glycol (PEG) and extended with chain extenders (CSN and CRN). Structural characterizations of prepared materials were examined through a fourier transformed infrared (FTIR) spectrophotometer.

This study aimed to investigate the impact of the malolactic fermentation (MLF) carried out by on antihypertensive and antioxidant activities in cider. The MLF was induced using three strains of . The modification in phenolic compounds (PCs) and nitrogen organic compounds, antioxidant, and antihypertensive activities were determined after MLF.
