Activation of the Akt/FoxO3 signaling pathway enhances oxidative stress-induced autophagy and alleviates brain damage in a rat model of ischemic stroke
Can J Physiol Pharmacol. 2022 Oct 31. doi: 10.1139/cjpp-2022-0341. Online ahead of print.ABSTRACTAutophagy has been implicated in stroke. Our previous study showed that the FoxO3 transcription factor promotes autophagy after transient cerebral ischemia/reperfusion (I/R). However, whether the Akt/FoxO3 signaling pathway plays a regulatory role in autophagy in cerebral I/R-induced oxidative stress injury is still unclear. The present study aims to investigate the effects of the Akt/FoxO3 signaling pathway on autophagy activation and neuronal injury in vitro and in vivo. By employing LY294002 or insulin to regulate the Akt/Fo...

The Truth About Fasting and Type 2 Diabetes
Most fad diets don’t live up to the hype, let alone serious scientific scrutiny. But intermittent fasting seems to be an exception. These plans involve going without caloric foods or drinks for an extended period of time—anywhere from 16 hours to several days—and they have become increasingly popular. Research has also found them to be effective for weight loss. Doctors often advise people with Type 2 diabetes to lose weight, which can have beneficial effects on blood glucose and insulin sensitivity, as well as on the progression of the disease. For this and other reasons, experts are actively looking at ...

Let Plants be Thy Medicine – You Are What You Eat
Credit: Busani Bafana/IPSBy Esther Ngumbi and Ifeanyi NsoforILLINOIS, United States / ABUJA, Oct 16 2019 (IPS) United Nations World Food Day is celebrated around the world on October 16 under the theme: “Our Actions ARE Our Future. Healthy Diets for a Zero Hunger World”. This theme is timely, especially, because across Africa and around the world, there has been a gradual rise in malnutrition and diet-related non communicable diseases, as highlighted in The Lancet study and a United Nations Report published earlier this year. While 45 percent of deaths in children are from nutrition-related causes, mainly malnu...

Sex Difference of Radiation Response in Occupational and Accidental Exposure
Conclusion and Outlook This review summarizes the data from major human studies on the health risks of radiation exposure and shows that sex can potentially influence the prolonged response to radiation exposure (Figure 1 and Tables 1, 2). These data suggest that long-term radiosensitivity in females is higher than that in males who receive a comparable dose of radiation. Our analysis of the literature agrees with the conclusions of the recent report on the Biological effects of ionizing radiation (BEIR VII) published in 2006 by the National Academy of Sciences (NAS), United States (National Research Council, 2006). The B...

Atrial Transcriptional Profiles of Molecular Targets Mediating Electrophysiological Function in Aging and Pgc-1 β Deficient Murine Hearts
Conclusion: These findings limit the possible roles of gene transcriptional changes in previously reported age-dependent pro-arrhythmic electrophysiologial changes observed in Pgc-1β-/- atria to an altered Ca2+-ATPase (Atp2a2) expression. This directly parallels previously reported arrhythmic mechanism associated with p21-activated kinase type 1 deficiency. This could add to contributions from the direct physiological outcomes of mitochondrial dysfunction, whether through reactive oxygen species (ROS) production or altered Ca2+ homeostasis. Introduction Atrial arrhythmias constitute a major public health pro...

Asymptomatic Carotid Stenosis Is Associated With Circadian and Other Variability in Embolus Detection
Conclusions: Embolism associated with asymptomatic carotid stenosis shows circadian variation with highest rates 4–6 h before midday. This corresponds with peak circadian incidence of stroke and other vascular complications. These and ASED Study results show that monitoring frequency, duration, and time of day are important in ES detection. Introduction Transcranial Doppler (TCD) detected microembolism in the ipsilateral middle cerebral artery (MCA) may help stratify the risk of stroke and other arterial disease complications in persons with advanced (≥60%) asymptomatic carotid stenosis. If so, this t...

Featured Review: Mediterranean-style diet for the prevention of cardiovascular disease
In this Q&A we asked the lead author Professor Saverio Stranges from Western University Canada to explain more about the mediterranean diet and its role in preventing cardiovascular disease following the publication of aCochrane Review on this topic. What makes a diet ‘Mediterranean’?Scientific interest in the traditional Mediterranean dietary pattern originated in the 1960s because of the observation that populations in countries of the Mediterranean region, such as Greece and Italy, had lower mortality from cardiovascular disease compared with northern European populations or the US, probably as a result of diff...

Activated Mast Cells Mediate Low-Grade Inflammation in Type 2 Diabetes: Interleukin-37 Could be Beneficial
Publication date: Available online 31 January 2018Source: Canadian Journal of DiabetesAuthor(s): Pio Conti, Gianpaolo Ronconi, Spyridon K. Kritas, Alessandro Caraffa, Theoharis C. TheoharidesAbstractMast cells (MCs) promote guest immune responses to parasites and play a critical role in allergic and inflammatory reactions. Once they have been activated, MCs release highly inflammatory compounds that can provoke serious pathologic signs that can lead to death. MCs generate a number of preformed, de novo synthesized compounds and inflammatory cytokine/chemokine synthesis in response to the high-affinity (Kd=10–10 M) immuno...

Association of Long-Term Exposure to Transportation Noise and Traffic-Related Air Pollution with the Incidence of Diabetes: A Prospective Cohort Study
Conclusion: We found a positive association between residential transportation noise and diabetes, adding to the growing body of evidence that noise pollution exposure may be independently linked to metabolic health and should be considered when developing public health interventions. https://doi.org/10.1289/EHP1279 Received: 26 October 2016 Revised: 07 May 2017 Accepted: 09 May 2017 Published: 31 August 2017 Address correspondence to C.
