Taking more vitamin A may help, according to a new study The study of about 125, 000 Americans found that people with the highest vitamin A intake had a 15 percent reduced risk of squamous cell skin cancer Most of the vitamin A they take comes from food "These findings just give us another reason to eat a healthy diet of fruits and vegetables Vitamin A from plants is safe "Eunyoung CHO, co-author of the study and associate professor of Dermatology and epidemiology at Brown University, said According to NIH, the healthy food sources of vitamin A include sweet potato, Hami melon, carrot, black eyed bean, sweet pepper, broccoli, spinach, dairy products, fish and meat, especially liver Photo source: cc0 public domain [6] menopause: vitamin D and estrogen may help effectively resist the occurrence of heart disease, stroke and diabetes doi: 10.1097/gme.0000000000001370 Now researchers have confirmed that vitamin D and estrogen can improve women's bone health Recently, in a research report published in the international journal menopause, scientists from institutions such as Sun Yat sen University found that the same combination (vitamin D and estrogen combination) can help inhibit metabolic syndrome (me) Metabolic syndrome increases the risk of heart disease, stroke and diabetes in postmenopausal women Nowadays, metabolic syndrome has become a major public health problem faced by the global population It affects the health of 30% - 60% of postmenopausal women With the growth of women's age, it leads to the development of abdominal obesity and heart disease of metabolic syndrome The significant increase, which seems to be directly related to the loss of estrogen in postmenopausal women, often leads some researchers to suggest that postmenopausal women less than 6 years use estrogen as a means of preventing heart disease 【7】 J Clin Oncol: vitamin D makes cancer patients live longer doi: 10.1200/jco.2019.37.15_supply.1534 doctors at Michigan State University found that taking vitamin D for at least three years can help cancer patients live longer The research results show that vitamins have significant benefits in addition to promoting bone health The research results were published at the annual meeting of American Society of clinical oncology on June 3, 2019 Cancer is the second leading cause of death in the United States, according to the Centers for Disease Control and prevention "Vitamin D can significantly reduce the risk of death in cancer patients, but unfortunately there is no evidence that it can prevent cancer 【8】 Cell res: unexpected discovery! Vitamin B12 may be able to treat hereditary Parkinson's disease! Doi: 10.1038/s41422-019-0153-8 researchers from biofisika Research Institute and other institutions found a new inhibitor that may be developed to fight Parkinson's disease through research, and relevant research results were published in the Journal of cell research Parkinson's disease is the most common chronic neurodegenerative motor disorder, affecting 1% of the global population over the age of 70 So far, there are no drugs to treat the disease, and the existing treatment is only to deal with its symptoms, but can not delay its progress Although most cases of Parkinson's disease are sporadic, the genetic variation of this disease is mainly related to the gene mutation encoding LRRK2 enzyme In 2004, an international team of researchers found a mutation in the enzyme linked to the disease in patients LRRK2 enzyme, also known as dardardardardina, which means "tremor" in Basque, has become the most attractive therapeutic target for the development of anti hereditary Parkinson's disease The neurotoxicity and pathogenicity related to LRRK2 are mainly due to the increased kinase activity of pathogenic mutations, which prompted the international competition to develop LRRK2 inhibitors At present, there are powerful inhibitors with specific activity of LRRK2 kinase, but many of them will have adverse side effects or very unclear clinical results 【9】 Cell stem cell: vitamin B3 homologues help produce blood cells doi: 10.1016/j.stem.2019.02.012 stem cell-based therapies are becoming more and more common, especially for diseases such as leukemia and lymphoma, in which case patients' cancerous blood stem cells are removed and replaced with healthy new stem cells But about a quarter of patients die because the blood cells update too slowly One solution is to enhance the division of so-called hematopoietic stem cells, a type of stem cells that produce different blood cells Therefore, promoting the division of hematopoietic stem cells is the most ideal solution, but how to achieve it? Scientists have known that stress slows down the division of hematopoietic stem cells, leading to a lack of supply of blood cells Biologically, stress can increase mitochondrial activity In order to meet the high demand of regenerating blood cells, a reaction called oxidative phosphorylation in mitochondria of hematopoietic stem cells will increase, thus providing energy for cells, but this will bring problems: increasing the activity of mitochondria will lead to the premature aging of hematopoietic stem cells Recently, in a research report published in the international journal Cell stem cell, researchers from the Federal Institute of technology and other institutions in Lausanne, Switzerland, found that a homologue of vitamin B3 (nicotinamide ribose) can increase the activity of hematopoietic stem cells through research This research focuses on stem cells Treatment has a profound impact, especially with niacinosyl, a daily supplement 【10】 JCI: Vitamin C can inhibit the production of tumor stem cells! Doi: 10.1172/jci121685 cancer is a word that makes people smell color change, and makes people feel fear and anxiety So many women with cancer and treatment experience chronic stress and depression Scientists have found in experiments in humans and rodents that stress accelerates cancer progression, but it's not clear what's behind it Recently, a report by Dalian Medical University and Zhongshan University was published in Journal of clini
