Guide Previous studies have confirmed that running can slow the progression of Parkinson's disease, but the molecular reasons behind this have been a mystery. Recently, scientists have given the answer - exercise can prevent the accumulation of alpha-synuclein in brain cells. The study was led by Dr. Wenbo Zhou, an associate professor at the University of Colorado, Anshutz Medical School, and Dr. Curt Freed, director of the Department of Clinical Pharmacology and Toxicology. The results were published in the journal PLOS ONE. "Our findings suggest that exercise can slow the progression of Parkinson's disease by preventing abnormal accumulation of alpha-synuclein in the brain," Dr. Freed said. As a chronic, progressive dyskinesia, Parkinson's disease has long been thought to occur as a result of the death of nerve cells or neurons in the brain's brain-controlled areas of the brain. Researchers speculate that abnormal accumulation of alpha-synuclein is one of the causes of neuronal cell death and is also considered a biomarker of Parkinson's disease. In this study, the researchers began a three-month observation of the neuroprotective effects of the mice in motion by loading a roller in a 12-month-old mouse cage. Zhou said: "We observed that the experimental group had much better motor and cognitive function than the control group. The researchers found that exercise increased the expression of key DJ-1 genes in the brain and muscle of experimental mice, with an accompanying increase in DJ-1 protein concentration in muscle and blood. In the control group, the DJ-1 knockout mice, the exercise capacity was severely decreased. This indicates that the DJ-1 protein is required for normal exercise. It is understood that those born with mutations in the rare DJ-1 gene will develop severe Parkinson's disease at a young age. According to Freed, this animal experiment has very practical implications for humans because it shows that exercise can reach the heart of Parkinson's disease. For the time being, although there has been no observational study of long-term exercise in animal models of Parkinson's disease. But long-term exercise can prevent the occurrence of age-related neurodegenerative diseases, so let's move!

The cotton pad is generally a small piece of cotton about 5-6 cm in length that is pressed from cotton or paper pulp. The main purpose is to remove makeup, and it can also be used for makeup.
2. It must also have a super water release capacity, and no cotton wool will be left after use.

There are basically two types of cosmetic cotton materials: absorbent cotton and non-woven fabrics. These two materials have their own advantages and disadvantages, and you can choose according to your needs.
Absorbent cotton
The cotton pad is thick and soft to the touch, and requires a large amount when used for applying toner; sometimes it has the phenomenon of desquamation and weak water absorption.
Non-woven fabric
This kind of cotton pad is relatively thin and has a coarser touch, but because of its strong water absorption, the amount of toner is relatively small.
Choice of cotton pads
1. Pour the standard amount of toner 2ML on the cotton pad to test the water absorption of the cotton pad. Test standard: see if there is any leakage of toner.
2. Squeeze out the lotion from the cotton pad that has absorbed the water to see how much water can be released. Test standard: how much ML lotion to squeeze out.
3. Wipe the back of the hand with a wet cotton pad for 20 times to see if there is any lint residue. Test standard: See how much cotton wool remains on the back of the hand.
Result analysis:
1. High-quality cotton pads need to have excellent water absorption capacity and will not drip at all.
