Introduction: Studying the
use of psychoactive substances in completed suicide is essential in order to
understand its role in the suicide generating stimuli. The most commonly
reported substances are alcohol and opioids. Method: This is a retrospective
study of completed suicide database of the Forensics Medical office in the city
of Mexicali from 1999 to 2005. This is the capital of the Mexican state of Baja
California in the US-Mexico border region. Results: Out of 288 suicides, 260
were men, and the most frequent drug found on autopsy was methamphetamine (p < 0.001). The modal victim was a
young male (20 - 39 years old), employed in blue-collar jobs, lived in an urban
area, found in their homes, and died by hanging. Discussion: Although no
causal effect can be drawn, our study results suggest that methamphetamine use
may be a risk factor for suicide in this sample.
The aim of this study was to describe the compositional,
functional and sensory properties of six traditional Mexican cheeses: Panela,
Oaxaca, Manchego, Manchego Botanero, Tenate, and Morral. A total of 50 cheeses
were analysed. Relevant compositional parameters including pH, aw,
proximate composition, NaCl, sugars, lactic and acetic acids, mineral contents,
free-amino acid nitrogen, fat acid degree value and total fatty acids were determined.
In addition, colour and texture profile analyses of unmelted cheeses and their
meltability were investigated. Furthermore, other 30 cheeses were used for a
descriptive sensory analysis. Properties of cheeses were described, compared
between each cheese, and related to their respective making processes.
