Piel electrónica para medir constantes vitales

de ALICIA RIVERA. ELPAIS.COM
La frontera entre la electrónica y la biología empieza a hacerse borrosa, según un equipo de ingenieros y científicos que ha desarrollado una piel artificial electrónica con enorme potencial en aplicaciones médica. Cargado de diferentes tipos de sensores, el parche de piel artificial, que se pega a la natural como un tatuaje temporal, se ha ensayado ya con éxito para medir la actividad eléctrica del corazón, del cerebro y de músculos. Su aplicación para sustituir los incómodos electrodos y cables que se utilizan para el diagnóstico y seguimiento cardíaco, parece evidente, pero las puertas que abre esta nueva piel artificial electrónica son enormes: los investigadores apuntan, por ejemplo que podrán construir sensores para medir la actividad cerebral en condiciones normales, sin recurrir a los aparatos equipos que se utilizan ahora, lo que permitirá investigar realmente cómo funciona el cerebro cuando la persona hace su vida normal. También se podrían hacer pieles sensibles para prótesis de extremidades amputadas o transmisores que, pegados a la garganta, faciliten la comunicación de personas con lesiones que limiten su capacidad de hablar. John A. Rogers, Dae-Hyeong Kim y el resto de los autores de este avance, explican cómo lo han hecho y los resultados de sus primeros ensayos en la revista Science. (VER MÁS)

Light Therapy holds promise as a treatment for Alzheimer's Disease

A new article, conducted by Lili Zang and colleagues from Weifang Medical University School of Nursing in Shandong Province, China, discusses a meta-analysis of 15 high-quality trials that investigated the impact of light therapy on individuals with Alzheimer’s disease (AD). The meta-analysis included 598 patients with mild to moderate Alzheimer’s disease, and it covered 15 randomized controlled trials conducted in seven different countries. Those trials were published between 2005 and 2022. Sleep Improvement Light therapy led to significant improvements in several sleep measures. It notably enhanced sleep efficiency, increased interdaily stability, and reduced intradaily variability, all of which are indicators of better sleep quality. Light therapy was associated with a reduction in agitation, depression, and caregiver burden among individuals with Alzheimer’s disease. A significant advantage over usual care was shown in reducing the severity of psychobehavioral symptoms, as assessed

Carvacrol: Health benefits from aromatic herbs (oregano, thyme)

Carvacrol is a phenolic monoterpenoid found in various essential oils. Oregano, thyme, and bergamot contain carvacrol. It boasts a range of beneficial properties for potential clinical applications. This compound has shown antimicrobial, antioxidant, and anticancer activities. It showed antimicrobial efficacy against food-borne pathogens like Escherichia coli and Salmonella. It is attributed to a unique combination of its chemical characteristics. Carvacrol, often used alongside thymol (another phenolic monoterpenoid found in these oils), exhibits high antioxidant activity and has been employed as a dietary additive to enhance the antioxidant status in animals (I.E. in poultry nutrition) Preclinical studies suggest promising anticancer properties of carvacrol, particularly in breast, liver, and lung carcinomas, through (proapoptotic) mechanisms involving elimination of DNA abnormalities. However, despite a well-defined toxicological profile, the lack of human trials hinders conclusive

Obesity, Zinc supplement and cognitive function

In a recent study, researchers were concerned about the impact of obesity on cognitive health, Even knowing that obesity is linked to cognitive decline and problems with the brain, they investigated if giving overweight or obese women a zinc supplement could help. In the study participated 42 women aged 40 to 60 and were splitted into two groups. One group received a zinc supplement (30 mg per day), while the other received placebo, for 12 weeks. Information about these women, like age, weight, diet, and physical activity was collected. To measure cognitive function and mood, various tests and questionnaires were used. They also checked certain substances in women's saliva to understand what was happening in their bodies. The results showed that the women who took the zinc supplement had better scores in cognitive tests, even though they didn't lose weight. This suggests that taking zinc might help overweight or obese women maintain better cognitive function, regardless of
