La falta de sueño aumenta los antojos de comida, según un nuevo estudio

Activa los mismos receptores que la marihuana,

Durante ya algún tiempo, varios estudios han revelado que la falta de sueño puede provocar obesidad. Pero ahora los investigadores están explorando los mecanismos que llevan a nuestros cerebros a sentir antojos de comida que no necesitan por falta de sueño.

Un estudio publicado recientemente en la revista SLEEP sugirió que los receptores cerebrales culpables de los antojos en personas que no han dormido son los mismos que se activan con la marihuana. Básicamente, no dormir puede provocar hambre, mucha hambre.

El estudio exploró los receptores afectados por los endocanabinoides -nombrados a partir del cannabis- que están involucrados con los antojos que resultan por la falta de sueño. La reducción del sueño en los sujetos de estudio causó niveles amplificados de endocanabinoides en la sangre, lo cual provocó más ataques de hambre. (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...

Los no fumadores engordan menos

Un nuevo estudio relaciona el tabaquismo con la ganancia de peso, y concluye que las personas fumadoras activas, no sólo las que lo dejan, engordan más que las no fumadoras. Después de cuatro años de análisis en la Universidad de Navarra, las personas que menos engordaron fueron las que nunca habían fumado.

Lacticaseibacillus rhamnosus may help in periodontal disease

A new study explores how a specific probiotic, Lacticaseibacillus rhamnosus GG (LGG), might help improve the regeneration of bones in the gums affected by periodontal disease, especially in the presence of high cholesterol levels (hyperlipidemia). Periodontal disease can lead to the loss of bone in the jaw, making it challenging for the bone to regenerate. The researchers used a rat model with conditions mimicking periodontal disease, high cholesterol, and a defect in the gums. The rats were given LGG for six weeks, and then various measurements were taken after sacrificing the rats to understand the effects. They found that the bone density, volume, and thickness in the affected area increased after the rats were given LGG. Interestingly, these improvements were not due to direct effects on the oral bacteria but were linked to changes in the gut microbiota. When fecal matter containing the altered gut bacteria from LGG-treated rats was transplanted into other rats, si...
