Effect of the partial substitution of mango and ground chia on the antioxidant capacity in the elaboration of nectar based on sachatomate.

The consumption of products with high nutritional value and antioxidant capacity has increased notably in recent years. Due to health problems such as triglycerides and cardiovascular problems, its use is becoming reduced. So that, chia (Salvia hispánica) and sachatomate (Cyphomandra betacea) have gained interest as an alternative to develop nutraceutical products, compared to conventional products. The objective of the study was to determine the effect of the partial substitution of mango (Mangifera indica) and ground chia (Salvia hispánica) on the antioxidant capacity in the elaboration of nectar based on Sachatomate. The physicochemical characteristics were determined where sample 11 complies with the established parameters: 13.4° Brix, pH 4.323, 0.354 of C6-H8-O7 and viscosity 3967.3 mPas, according to the NTP 203.110 standard. Regarding the antioxidant capacity, sample 12 was the most optimal, according to the DPPH method, it has been determined 104.3 micromoles Trolox equivalents; according to the ABTS method, it was determined with an antioxidant content of 187.4 micromoles Trolox equivalents. Regarding the proximal chemical evaluation, sample 12 was determined to be the most suitable with a moisture percentage of 87.45%, ash 0.32%, crude fiber 0.09%, fat 0.10%, protein 0.45% and carbohydrates 11.59%. Concluding that substituting sachatomate and ground chia significantly influences the antioxidant capacity, increasing to 104.3 and 187.4 micromoles Trolox equivalents, determined by both methods, indicates that nectar consumption can be used to improve the health of consumers.

Effect of different concentrations of stem juice of Oxalis tuberosa Mol. and juice of the fruit of Gaultheria glomerata (Cav.) Sleumer on the antioxidant activity of the heat-treated functional beverage.

Functional beverages with added health benefits are popular among peoples and athletes because they help them recover faster from intense workouts and perform better overall. This research set out to determine how well heat-treated stem juice from Oxalis tuberosa Mol. "oca" and fruit juice from Gaultheria glomerata (Cav.) Sleumer "laqa-laqa" performed as an antioxidant in a functional drink. The "oca" stems and the "laqa-laqa" fruit were collected to obtain the juice. For this study, 30 semi-trained panellists used sensory evaluation to rate four treatments (Bo, B1, B2, and B3) with varying quantities of "oca" and "laqa-laqa" juice. The results concluded that the treatment B2, which included 300 ml of "oca" stem juice, 800 ml of "laqa-laqa" juice, 1000 ml of treated water, and 220 g of refined sugar, was given the highest score after a physicochemical evaluation of its colour, smell, taste, and overall appearance. Similarly, the results showed that the protein content increased by 1.38%, the fat content by 1.08%, the moisture percentage by 99.5%, the ash content by 1.82%, and the carbohydrate content by 6.22% after B2 treatment. Similarly, results revealed significant enhancement in antioxidant profiling such as total polyphenols: 1825 mg of gallic acid/100 g and antioxidant Activity: 89.56% µmol of trolox /100 g. In conclusion, due to its high energy content and antioxidant activity, it may be a viable nutritional option for athletes who engage in rigorous, frequent physical exertion.

A comprehensive review on monitoring and purification of water through tunable 2D nanomaterials.

Instead of typical household trash, the heavy metal complexes, organic chemicals, and other poisons produced by huge enterprises threaten water systems across the world. In order to protect our drinking water from pollution, we must keep a close eye on the situation. Nanotechnology, specifically two-dimensional (2D) nanomaterials, is used in certain wastewater treatment systems. Graphene, g-C3N4, MoS2, and MXene are just a few examples of emerging 2D nanomaterials that exhibit an extraordinary ratio of surface (m3), providing material consumption, time consumption, and treatment technique for cleaning and observing water. In this post, we'll talk about the ways in which 2D nanomaterials may be tuned to perform certain functions, namely how they can be used for water management. The following is a quick overview of nanostructured materials and its possible use in water management: Also discussed in length are the applications of 2D nanomaterials in water purification, including pollutant adsorption, filtration, disinfection, and photocatalysis. Fluorescence sensors, colorimetric, electrochemical, and field-effect transistors are only some of the devices being studied for their potential use in monitoring water quality using 2D nanomaterials. Utilizing 2D content has its benefits and pitfalls when used to water management. New developments in this fast-expanding business will boost water treatment quality and accessibility in response to rising awareness of the need of clean, fresh water among future generations.

Photosynthetic modification of plants through recent technologies: a valuable way to ensure crop fortification.

The 2030 Sustainable Development Goals of the United Nations include a strong emphasis on ending hunger worldwide. According to the 2019 Global Food Security Index, while 88% of countries claim there is sufficient food supply in their country, the sad reality is that 1 in 3 countries is facing insufficient availability of food supply, which means that in those countries, more than 10% of the population is malnourished. Since nutrition is crucial to leading a healthy life and satisfying food security needs, several governments have turned to national nutrition surveys to gauge the extent of malnutrition in their populations. Plants are able to grow, develop, and store nutrients by photosynthesis, which convert light into chemical energy through cell redox regulatory networks. A photosynthesis system's electron flow may be adjusted to accommodate varying light and environmental circumstances. Many techniques exist for controlling the flow of electrons emitted during light processes in order to save or waste energy. The two protein molecules TROL and flavoenzyme ferredoxin (oxidoreductase+NADP) (FNR) interact dynamically to form an excellent molecular switch capable of splitting electrons from the photosystem. The TROL-FNR bifurcation may be limited by either generating NADPH or preventing reactive oxygen species from propagating. TROL-based genome editing is an experimental method for enhancing plant stress and defensive responses, efficiency, and ultimately agricultural production.

Adenovirus entéricos serotipos 40 y 41 en lactantes con diarrea aguda / Serotype 40 and 41 enteric adenovirus in infants with acute diarrhea

Los adenovirus entéricos, del subgénero F, serotipos 40 y 41, han sido reconocidos como agentes etiológicos de diarrea aguda, especialmente en lactantes. Una gran parte de las infecciones por estos virus parecen ser asintomáticas. Ellos constituyen una de las tres primeras causas identificables de diarrea aguda en lactantes y preescolares y la segunda en brotes ocurridos en salas cunas. Se buscaron adenovirus entéricos serotipos 40 y 41 en las deposiciones de 96 lactantes consecutivos, hospitalizados con diarrea, con el propósito de hacer una descripción inicial de su incidencia, mediante una técnica de anticuerpos monoclonales serotipo específicos, detectándose en dos casos, cuyas características clínicas no diferían de lo ya descrito para este agente viral, destacando la ausencia de fiebre, la presencia de mucus en las deposiciones y de deshidratación leve y la duración de cinco días en ambos pacientes

Participación viral en las infecciones respiratorias agudas bajas del lactante / Viral participation in lower respiratory tract infections

Se determinó la participación viral en 344 lactantes con IRA bajas desde 1983 a 1985 utilizando técnicas de aislamiento, detección de antígeno y serología viral. Se confirmó una positividad viral global en 59,6% de los casos (n=205), siendo los principales virus detectados: virus respiratorio sincicial (VRS: n=134; 65,4%), adenovirus Ad; n=41; 20%) y parainfluenza (PI: n=25; 12,7%). En un 16,6% (n=34) de las IRA estudiadas se confirmaron 2 o más virus. El VRS predominó en todos los grupos, especialmente en los menores de 6 meses. Los PI aumentaron con la edad y los Ad mostraron un incremento menos notorio. El VRS fué el único agente en enfermedad bronquial obstructiva y predominó en todos los diagnósticos. Los Ad y PI se encontraron en todos los cuadros, sin predominio determinado. Se detectaron también virus influenza y citamegalovirus, este último sin un claro papel patógeno. La inmunofluorescencia sería la técnica de elección para VRS en nuestro medio y el aislamiento para los Ad. Se confirma la importancia de los virus estudiados como agentes causales de IRA y se destaca la necesidad de completar los estudios etiológicos con técnicas para otros patógenos no virales

Adenovirus en niños con infecciones respiratorias agudas bajas / Adenovirus in lower respiratory tract infections

Se estudiaron 78 casos clínicos hospitalizados por infección respiratoria aguda baja durante los años 1983 a 1986. En todos se confirmó Adenovirus (Ad.) por aislamiento viral, detección de antígeno en aspirado nasofaríngeo o serología pareada. De las técnicas para diagnóstico virológico empleadas, el aislamiento viral fue la de mayor positividad (66/78 casos). Se analizaron las características personales de los pacientes, factores de riesgo de adquirir infección grave por Ad., manifestaciones clínicas y resultados virológicos obtenidos. De los 78 casos estudiados, el 69,2% eran menores de un año. En el 43,6% de los enfermos ocurrió infección viral mixta, la que prevaleció significativamente también en menores de un año. Uno de los factores de riesgo presente con mayor frecuencia fue el antecedente de patología respiratoria, ya sea ambulatoria, hospitalaria o ambas. La evolución clínica fue generalmente larga y con las características ya conocidas para las infecciones por Ad. Entre los exámenes de laboratorio destacan: lo poco característico del hemograma, la tendencia a la hipoxemia y las alteraciones radiológicas con una alta frecuencia de imágenes de neumonitis, condensación e hiperinsuflación pulmonar. La letalidad de los casos estudiados fue de 7,7% (6 casos)
