Posttraumatic stress disorder (PTSD) is an anxiety disorder caused by the experience of a severe traumatic event. In rats this disorder has been modeled by exposure to a predator threat. PTSD has been associated to structural and functional changes in the medial prefrontal cortex (mPFC). Direct injections into this brain region of glutamate antagonists or inhibitors of the nitric oxide synthase (NOS) enzyme cause anxiolytic-like effects in rodents

"When cortisol levels remain elevated, as is the case with so many people who are under constant stress, the ability to reproduce can suffer greatly," Josephs said. "However, these effects of cortisol in both men and women are reversed when stress levels go down."

High levels of the stress hormone cortisol play a critical role in blocking testosterone's influence on competition and domination, according to new psychology research at The University of Texas at Austin.

Eating vegetable oils could lead to fatigue, migraines and dementia | New York Post

While Shanahan claims that vegetable oils can wreak havoc on all areas of the body, she’s particularly concerned about the brain. Regularly consuming vegetable oils can lead to lethargy and trouble concentrating in the short term, she believes, and, in her view, might trigger brain conditions, such as Alzheimer’s or dementia, down the line. “Oxidative stress disrupts the function of the brain, so the cells cannot do their normal housekeeping,” in her opinion, which allows plaque to build up in the brain.

While unsaturated vegetable oils seemed healthy at first, recent research has shown that the processed oils may be more destructive than the fats they replaced. One re-evaluation of a heart study from the 1970s, published in April in the British Medical Journal, questioned the original finding that consuming vegetable oils instead of saturated fats can lower the risk of heart disease and death. In fact, it found that consuming too much vegetable oil may actually increase the risk of heart disease.

The study, which was published on Japan's Excite News website Tuesday, compared participant’s brain activity in people who had been given ice cream immediately after waking up with those who had not eaten ice cream. Koga found that people who had consumed ice cream for breakfast showed better reaction time and were able to process information better than those who did not have the ice cream.

Frontiers | Living at a Geographically Higher Elevation Is Associated with Lower Risk of Metabolic Syndrome: Prospective Analysis of the SUN Cohort | Exercise Physiology

Our results are novel, but they are in line with other studies that did not specifically assessed MetS. Regarding to living at high altitudes, several observational studies have reported lower incidence rates of metabolic diseases in different large cohorts (Ezzati et al., 2012; Voss et al., 2013, 2014; Woolcott et al., 2014; Faeh et al., 2016). Obesity was significantly higher at lower altitude category (<500 m) in an US cross-sectional study after controlling for urbanization, temperature, behavioral and demographic factors (males and females had 5.1 and 3.9 times the odds of obesity, respectively, compared to participants over 3000 m) (Voss et al., 2013). A study about the incidence of overweight/obesity at geographical altitude performed in the SUN cohort found a reduction in the risk of developing overweight or obesity (Diaz-Gutierrez et al., 2016).

The higher concentration of oxygen (O2) that can be found in the earth corresponds to sea level (21%). At this altitude level the O2 partial pressure (pO2) is around 160 mmHg. Every 300 m reduces the pO2 1% (McElroy et al., 2000; West, 2002). Our study suggests a potential preventive effect of living at moderately geographical altitude where the participants are exposed to lower pO2, pressure, humidity and temperature.
