This study shows that overweight or obese volunteers who had eaten avocado as part of a meal felt less hungry after 6 hours, compared with those who had eaten a low-fat, high-carbohydrate meal because avocado contains a rare combination of healthful fats and fiber and is associated with many health benefits.
The authors discovered that the bacterial species *Clostridioides difficile*, which is known for causing serious diarrheal infections, is responsible for certain colorectal cancers.
This is the largest and longest avocado research study (more than 1,000 participants) which is conducted by 5 universities, and it showed that eating one avocado every day for six months had no impact on waist circumference, belly fat, or liver fat in those who were overweight or obese, but it decreased their unhealthy cholesterol levels.
The authors defined how the circadian clock influences cell growth, metabolism, and tumor progression - they demonstrated that both genetic and environmental disruption of the circadian clock can drive colorectal cancer progression.
The authors identified a possible explanation why women may not react to treatments for depression similarly to men as women usually have greater rates of depression than males - depression symptoms may have been triggered by alterations of the nucleus accumbens (i.e. specific genes were switched on or off in women with depression but not in males) or the depressive episode itself may have altered the brain.
This large study of US adults (491,367 participants, 62 years old on average) showed that high fish consumption (including tuna and non-fried fish) is related to an increased risk of cancer (i.e. malignant melanoma) - its incidence was 22% greater among individuals whose median daily consumption of fish was 42.8 grams as compared to those whose median daily intake was 3.2 grams.
The authors discovered that alcohol changes the synchronized brain activity in the amygdala of mice, but alcohol alters amygdala activity differently in male and female mice, which suggests that alcohol can trigger the amygdala to switch activity states and drive changes in anxious and fearful behavior.
The authors investigated 2,898 people (65 years old and older) over 30 years and discovered that people who have a non-alcoholic fatty liver disease (i.e. an accumulation of fat cells in the liver) could have a 38% higher risk of dementia.
The authors found an unexpected alteration in the brain (an accumulation of TDP-43 proteins rather than alpha-synuclein) during the autopsy of a patient with clinically typical Parkinson’s disease, which shows that a buildup of Lewy bodies is not the only way that Parkinson’s disease-related cell death can happen.
The authors successfully used bacteria-eating viruses to treat 20 complex and antibiotic-resistant lung infections without side effects, and more than half of the patients had favorable clinical results.
The authors developed a plastics recycling innovation that more efficiently converts plastics to valuable commodity chemicals, produces much less methane, and simultaneously increases conversion to useful products while using less of the precious metal ruthenium, which makes the catalyst much cheaper.
The authors revealed the genetic and molecular structure of certain key molecules connected to the potentially fatal mammalian-meat allergy caused by tick bites, which opens the door to potential future treatments: description of how antibodies interact with the sugar molecule galactose-α-1,3-galactose and that α-gal serves as the key molecule for this particular allergy.
This review included six randomized controlled trials (a total of 273 people) and it concluded that yoga can be a supportive and safe treatment for people with irritable bowel syndrome (IBS).
The author found that psychological stress can have a substantial impact on the motility, permeability, secretion, and overall sensitivity of the intestinal tract.
This is the world-first genetic study that shows a direct connection between high levels of inflammation and low levels of vitamin D by examining the genetic data of 294,970 participants in the UK. Hence, the study provides an important biomarker to identify people at higher risk of chronic inflammatory illnesses (e.g. type 2 diabetes, heart disease, and autoimmune diseases).
