ABSTRACT
RESUMEN La chía (Salvia hispanica L.) es una semilla originaria de la zona sur de México y Guatemala, que se ha expandido a otros países de latinoamérica. Esta semilla ha sido utilizada con diferentes fines a lo largo de la historia, donde se destaca como producto alimentario debido a su gran versatilidad, ya que puede ser utilizada como semilla, harina integral, fracciones de fibra y/o proteína y aceite. En la actualidad, la investigación de nuevas fuentes alimentarias que otorguen beneficios a la salud ha logrado recopilar información sobre la composición química y valor nutricional de esta semilla y sus derivados (harina y aceite), donde se encuentra principalmente el contenido de ácidos grasos poli-insaturados n-3, destacando el ácido alfa linolénico (C18:3n-3, ALA), que se propone como fuente alternativa de este nutriente a alimentos de otros orígenes, además el contenido de fibra de la chía, principalmente fibra insoluble. En cuanto a los beneficios que se asocian al consumo de chía, se ha visto que tiene estrecha relación con enfermedades crónicas no transmisibles como dislipidemia, diabetes, hipertensión, cáncer, entre otras, logrando captar la atención de investigadores para controlar y prevenir estas patologías que van en aumento en la población mundial. Por lo tanto, se hace relevante profundizar en los conocimientos disponibles sobre esta semilla y sus subproductos para poder establecer los posibles mecanismos moleculares que están involucrados en la generación de beneficios para la salud. El objetivo de esta revisión es presentar una actualización de los beneficios asociados al consumo de semilla de chía y sus derivados.
ABSTRACT Chia (Salvia hispanica L.) is a seed native to the southern part of Mexico and Guatemala, which has spread to other Latin American countries. This seed has been used for different purposes throughout history, where it stands out as a food product due to its great versatility, since it can be used as a seed, whole meal flour, fiber and/or protein fractions and oil. Currently, the investigation of new food sources that provide health benefits has managed to collect information on the chemical composition and nutritional value of this seed and its derivatives (flour and oil). For polyunsaturated fatty acid content, n-3 is found, highlighting alpha linolenic acid (C18:3n-3, ALA), which is proposed as an alternative source of this nutrient to foods of other origins. In addition, the fiber content of chia, is mainly insoluble fiber. Regarding the benefits associated with chia consumption, it is closely related to chronic non-communicable diseases such as dyslipidemia, diabetes, type II, hypertension, cancer, among others, managing to attract the attention of researchers to control and prevent these pathologies that are increasing in world population. Therefore, it is relevant to deepen the knowledge available about this seed and its by-products in order to establish the possible molecular mechanisms that are involved in generating health benefits. The objective of this review is to present an update on the benefits associated with consumption of chia seed and its derivatives.
ABSTRACT
BACKGROUND: Chia seeds are gaining increasing interest among food producers and consumers because of their prohealth properties. RESULTS: The aim of this work was to evaluate the potential of chia seeds to act as acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitors. The highest inhibitory activity against AChE and BChE was observed for colored seed ethanol extracts. A positive correlation was found between the presence of quercetin and isoquercetin as well as protocatechuic, hydroxybenzoic, and coumaric acids and the activity of extracts as AChE and BChE inhibitors. It has also been shown that grain fragmentation affects the increase in the activity of seeds against cholinesterases (ChE). Furthermore, seeds have been shown to be a source of substances that inhibit microbial growth. CONCLUSIONS: It was found that the chia seed extracts are rich in polyphenols and inhibit the activity of ChEs; therefore, their use can be considered in further research in the field of treatment and prevention of neurodegenerative diseases.

Objective: The purpose of the current study was to investigate balance in children with attention deficit hyperactivity disorder contrasted tonormal subjects. Furthermore, it studied the relationship between their balance and the total percentile scores of ADHD Rating Scale-IV.Design: The study was a cross-sectional design. Methods: Sixty children were involved in this research from both sexes (42 boys and 18girls) with age ranged from 60 to 84 months. They were subdivided into two groups based on the ADHD Rating Scale-IV. The control groupincluded 30 normally developed children from both sexes (20 boys and 10 girls) with a mean age of 67.53 ± 1.41 months, and the totalpercentile scores of ADHD Rating Scale-IV ≤ 50. The study group comprised of 30 children from both sexes (22 boys and 8 girls) withattention deficit hyperactivity disorder (ADHD) with a mean age of 68.60 ± 4.62 months. The total percentile scores of ADHD Rating ScaleIV were ≥ 93. Both groups were investigated for their balance by Pediatric Balance Scale (PBS). Results: According to the PBS scoring, thechildren with ADHD had significantly lower balance and total percentile scores of ADHD Rating Scale-IV than the children who arenormally developed. Furthermore, the PBS score and the percentile scores of ADHD Rating Scale-IV had a significant negative correlation.Conclusion: It can be concluded that children with ADHD had significant balance disturbance as contrasted to normal subjects. Thedisturbance in their balance was inversely correlated with the percentile scores of ADHD.
