"Delaying Rot Emergence in Persian Lime (Citrus×latifolia) Through Antifungal Hybrid Films Containing Litsea glaucescens Essential Oil".

Herein we describe the in situ inhibitory activity of three hybrid films (FL1, FL2, and FL3) against two wild strains of Colletotrichum gloeosporioides and Penicillium digitatum as causal agents of rot in Persian limes. The films FL2 and FL3 contained 1.0 and 1.3 % weight/volume Litsea glaucescens essential oil (LgEO) and significantly (p<0.05) delayed rot emergence in Persian limes caused by both pathogens up to 10 days. The physicochemical properties of LgEO and hybrid films were obtained, whereas detailed HPLC profiling revealed that fruit covered with these films significantly (p<0.01) preserved reducing sugars (sucrose, fructose, and glucose), organic acids (citric acid, ascorbic acid, malic acid, and oxalic acid), and flavonoids with nutraceutical activity (hesperidin, eriocitrin, naruritin, neohesperidin, diosmin, vitexin, rutin, and quercetin). This evidence sustains that the composites generated in this investigation improve the shelf life of Persian limes and conserve their nutraceutical content.

Epidemiology of environmental factors related to beta-catenin pathway and its impact on the development and progression of colorectal cancer.

Colorectal cancer (CRC) is a complex disease, determined by genetic, environmental and lifestyle-associated risk factors. Genetic (inherited) factors have great influence on its development; however, most cases of CRC are sporadic and gradually develop over several years. The main environmental risk factors are associated with b-catenin signaling pathway, including obesity, lack of physical activity, consumption of red and processed meats, alcoholism, and smoking. The pathway is related to cell homeostasis regulation and cell self-renewal during embryogenesis and adulthood. The main recommendation for preventing the development of CRC is to reduce the risk factors, increase the consumption of fruits, vegetables and grains, exercise regularly and limit the consumption of both alcohol and tobacco. However, family history and the presence of a hereditary syndrome increase the risk, which is why carrying out periodic examinations to detect CRC is suggested, using development predictors such as biochemical and molecular markers, which are discussed in this work.

El cáncer colorrectal (CCR) es una enfermedad compleja determinada por factores de riesgo genéticos, ambientales y de estilo de vida. Los factores genéticos (hereditarios) tienen gran influencia en su desarrollo, sin embargo, la mayoría de los casos de CCR son esporádicos y se desarrollan gradualmente a lo largo de varios años. Los principales factores ambientales de riesgo están asociados a la vía de señalización de ß-catenina, entre ellos obesidad, falta de actividad física, consumo de carnes rojas y procesadas, alcoholismo y tabaquismo. La vía está relacionada con la regulación de la homeostasis celular, autorrenovación celular durante la embriogénesis y edad adulta. La principal recomendación para evitar el desarrollo del CCR es reducir los factores de riesgo, aumentar el consumo de frutas, verduras y granos, hacer ejercicio de manera rutinaria y limitar el consumo tanto de alcohol como de tabaco. Dado que los antecedentes familiares y la presencia de un síndrome hereditario aumentan el riesgo, se sugiere hacer exámenes periódicos para detectar CCR y emplear predictores del desarrollo como los marcadores bioquímicos y moleculares, los cuales se presentan en este trabajo.

Fungistatic Films Containing Cinnamon Essential Oil: New Coatings to Preserve the Nutraceutical Content of Avocado Fruit against Fusariosis.

Avocadoes are a rich source of nutrients and nutraceuticals that preserve human health. Nevertheless, this fruit is susceptible to phytopathogen infection during the postharvest period causing severe economic losses. Herein, we report on the in situ antifungal assessment of biodegradable films impregnated with the essential oil of Cinnamomum verum (CvEO) as natural fungistatic coatings to extend postharvest quality of Hass avocadoes (Persea americana cv. Hass). These coatings were evaluated on fruits previously infected with a native strain of Fusarium verticillioides. The cytotoxic assessment of CvEO on F. verticillioides revealed a minimum inhibitory concentration of 0.3±0.0 g L-1 whereas its chemical profiling showed (E)-cinnamaldehyde (45.9 %) 1,3,8-p-menthatriene (7.9 %) and linalool (6.8 %) as the major bioactive compounds. Four coatings (FC1-FC4) were made using chitosan (1 %) and a diverse quantity of CvEO (0.4-1.3 % w/v). The physicochemical properties demonstrated that the films FC3 and FC4 have the optimal characteristics of a food coating. Avocadoes preserved with the films FC3 and FC4 substantially kept (p<0.01) fruit firmness and the nutraceutical content of infected avocados at least for 21 d. The results of the present investigation suggest that our hybrid materials can conserve basic nutritional parameters such as fiber, protein, reducing sugars, as well as the content of unsaturated fatty acids which are the main nutraceuticals of this fruit.

A FEMALE CASE OF SPINOCEREBELLAR ATAXIA TYPE 10 WITH SUICIDAL BEHAVIOR AND ENDOCRINPATHIES ASSOCIATED WITH A MASSIVE EXPANSION (ATTCT) OF THE GENE ATXN10.

Spinocerebellar ataxia type 10 (SCA10) is characteri- zed by ataxia, psychiatric disorders convulsions, and locus at 22q13.311. It is caused by expansions between 800-4500 pentanucleotide ATTCT repeats in intron 9 of the ATXN10 gene1-2. The ATXN10 gene encodes ataxin-10 protein (known as E46L) involved in neuritogenesis 1. SCA10 has a founder origin in Mexican, Brazilian, Argentine populattons but is rare in others.

New Genetic Polymorphisms as an Epidemiological Factor of Arterial Hypertension in Patients with Hyposodical Diet.

Hypertension is a major public health problem, affecting more than a quarter of the world's population causing serious cardiovascular problems. In recent years, different polymorphisms have been studied and helped to identify some candidate genes and hereditary syndromes associated with the molecular mechanisms involved in the development of hypertension. Therefore, it is important to identify these molecular mechanisms. This review exposes all the genes and polymorphisms that increase or decrease the risk of hypertension in different populations that are related to the renin angiotensin aldosterone system, G protein, salt excretion, aldosterone synthesis, lipid metabolism, mechanism of insulin resistance, vitamin metabolism, purines and sodium reabsorption. This document can be a useful tool in clinical practice, in addition to serving as a support for future research on this topic.

Peppermint Essential Oil and Its Major Volatiles as Protective Agents against Soft Rot Caused by Fusarium sambucinum in Cera Pepper (Capsicum pubescens).

Cera pepper (Capsicum pubescens) is an exotic fruit considered as a rich source of nutraceuticals with known benefits for human health and also an economic resource for local producers in Mexico. The present investigation reports on the in vitro and in situ antifungal activity of the essential oil from Mentha piperita and its two major volatiles (menthol and menthone) against Fusarium sambucinum, which is a causal agent of soft rot in cera pepper. The application of these components in pepper fruits previously infected with F. sambucinum caused a significant delay (p<0.05) in the emergence of soft rot symptoms. This effect was reflected in the maintenance of pH and fruit firmness during a period of 10 days. The nutrimental content of the fruits (protein, fiber, fat and other proximate parameters) was conserved in the same period of time. The nutraceutical content of these fruits was estimated by the quantification of seven carotenoids (violaxanthin, cis-violaxanthin, luteoxanthin, antheraxanthin, lutein, zeaxanthin and ß-carotene), ascorbic acid and capsaicinoids (capsaicin and dihydrocapsaicin). According to our results, the essential oil from M. Piperita and its major volatiles exerted a preservative effect on these metabolites. Our findings demonstrated that the essential oil of M. Piperita and its major volatiles represent an ecological alternative for the control of fusariosis caused by F. sambucinum in cera peppers under postharvest conditions.
