Men Are More Likely to Develop Parkinson's Disease - Jordan News
A new study has revealed that the risk of developing Parkinson's disease (also known as "shaking palsy") is twice as high in men as it is in women, suggesting a potential cause related to a harmless protein in the brain. اضافة اعلان This protein is called PINK1 kinase, and it is typically not harmful; it plays an important role in regulating cellular energy use in the brain. However, the new study shows that, in some cases of Parkinson's disease, the immune system mistakenly treats PINK1 as an enemy and attacks brain cells containing this protein. According to the study, conducted by a team from the La Jolla Institute for Immunology in California and based on blood samples from Parkinson's patients, damage to this protein caused by T-cells in the immune system is more widespread and aggressive in men's brains compared to women's. Immunologist Alessandro Sette, who participated in the study, said, "The sex-based differences in T-cell responses were truly remarkable." He added, "In male Parkinson's patients, we observed a six-fold increase in T-cells targeting brain cells that carry the PINK1 protein, compared to healthy brains. In female patients, there was only a 0.7-fold increase." Researchers pointed out that these findings could help develop treatments to prevent T-cells from attacking the PINK1 protein, thereby protecting brain cells.
It's important to note that Parkinson's disease is a neurodegenerative condition that gradually manifests with stiffness, tremors, and slow movement. The disease's symptoms are due to the death of important nerve cells in an area near the brainstem, which are indirectly involved in controlling fine motor skills.

What Is the Link Between Watching TV and Certain Diseases? - Jordan News
A new study has confirmed that watching television for four or more hours a day is associated with a higher risk of developing brain-related disorders such as dementia, depression, and Parkinson's disease. اضافة اعلان The study, published in the International Journal of Behavioral Nutrition and Physical Activity, analyzed data from more than 473,000 adults aged between 39 and 72, who were enrolled in the UK Biobank. Researchers followed participants over time until their death, monitoring diagnoses of dementia, Parkinson's disease, or depression. Participants also reported how many hours they spent outside of work engaging in activities such as exercise, computer use, or watching TV. Compared to people who watched TV for less than an hour per day, participants who reported watching for four hours or more daily had: A 28% higher risk of developing dementia A 35% higher risk of developing depression A 16% higher risk of developing Parkinson's disease Interestingly, participants who reported moderate computer use (30 to 60 minutes per day) appeared to have a lower risk of developing these three conditions compared to those with minimal computer use. However, since this was an observational study, the researchers emphasized that it cannot prove that excessive TV watching directly causes these conditions. It remains unclear whether it is a cause, an early sign, or simply linked to other contributing factors.

Beverages That Promote Hydration and Health Besides Water - Jordan News
Beverages That Promote Hydration and Health Besides Water Maintaining hydration is crucial for brain, gut, heart, and kidney health. It also helps regulate body temperature and prevents headaches. In addition to water, there are several other beverages that help hydrate the body while providing vitamins, minerals, antioxidants, and other nutrients. Here are some drinks that can enhance hydration and support overall health: اضافة اعلان Green Tea Green tea contains polyphenols, powerful antioxidants that help prevent cell damage and reduce inflammation. Drinking it has been shown to reduce the risk of diseases such as heart disease, cancer, Alzheimer's, and Parkinson's. Kombucha Kombucha is a fermented and sweetened tea that contains probiotics, which support gut health. It is also rich in polyphenols and may help lower cholesterol, prevent high blood pressure, improve liver function, and support gut health. Pomegranate Juice Pomegranate juice is rich in polyphenols and has heart health benefits. Studies show that drinking pomegranate juice daily can significantly lower blood pressure and reduce inflammation, as well as help manage diabetes. Kefir Kefir is a fermented milk drink that contains probiotics, which support gut health. It is an excellent source of calcium, vitamin D, and high-quality protein, which can benefit muscles and help you feel fuller longer. Sparkling Water Sparkling water is another option for staying hydrated. There are many flavored sparkling water options, but some may contain sweeteners that could raise blood sugar levels, so be mindful, especially for those with diabetes. Fruit Smoothies Fruit smoothies are a great way to consume more fruits and vegetables. They are rich in dietary fiber, which helps lower cholesterol, prevent constipation, reduce the risk of colon cancer, and aid in satiety. They also help prevent blood sugar spikes, making them more suitable for people with diabetes compared to fruit juice. Coffee Coffee contains beneficial plant nutrients, including chlorogenic acids, polyphenols, terpenoids, and alkaloids. Research shows that drinking coffee can help prevent inflammation, liver diseases, and neurological disorders. It may also help prevent colon and breast cancer. However, it's important not to exceed the safe caffeine intake, which is generally no more than four to five cups a day. Coconut Water Coconut water is often used as a natural sports drink. It contains potassium, sodium, magnesium, and calcium, which help support muscles and nerves, regulate heart rate, and maintain blood pressure. The potassium in coconut water may also help lower blood pressure. Some studies have found that drinking coconut water for a week can reduce blood pressure in adults with hypertension. Low-Fat Milk Milk is a good source of protein, making it an ideal post-workout drink to support muscle growth and rehydration. It also contains essential nutrients for bone health, including calcium, phosphorus, and vitamin D. Cranberry Juice Cranberry juice is a good source of vitamin C, an antioxidant that supports immune health. It is also rich in polyphenols that help prevent inflammation and may stop harmful bacteria from adhering to the walls of the bladder. Some research suggests that cranberry juice can help prevent urinary tract infections. Beetroot Juice Beetroot juice is rich in antioxidants, giving it its deep red color. It contains nitrates, which convert to nitric oxide after consumption. Nitrates help dilate blood vessels, improve blood flow, and lower blood pressure. Herbal Tea Herbal teas are caffeine-free and packed with nutrients. They contain antioxidants that help maintain cell health and prevent diseases like cancer, diabetes, and Alzheimer's. Each herbal tea has its unique flavor and health benefits. For example, ginger tea helps manage nausea, and hibiscus tea can help lower blood pressure. Adding these beverages to your daily routine can help hydrate your body while promoting overall health naturally.
