#护肤大道理# 脸上的“脂肪粒”怎样去除？
对于皮肤科医生来说，老百姓俗称的“脂肪粒”至少包含不下六种常见的小型皮肤增生物。通常会根据增生细胞的深度和大小选择相应的去除方式。
1. 最典型和常见的白色“脂肪粒”多为粟丘疹，是一种小的表皮样囊肿，可以通过针清、挤出、刮除、液氮冷冻、电灼等方式去除。
2. 之前提到的半透明的“水瘊子”（传染性软疣）也有可能被人误认为是“脂肪粒”，属于一种病毒感染性皮疹，首选刮除、挤出、液氮冷冻去除或涂抹咪喹莫特等抗病毒药物使之脱落。
3. 纯肉色或颜色稍浅一些的“脂肪粒”可能是汗管瘤、毛发上皮瘤、小汗腺汗囊瘤等来源于皮肤附属器的小型赘生物，多需通过二氧化碳激光灼烧或电灼的方式进行逐一去除；面积较大的也可通过剥脱性点阵激光的方式去除。
4. 纯黄色的“脂肪粒”有可能是黄色瘤或皮脂腺增生，前者可能与高脂血症有关，后者则可能与油性皮肤及皮肤局部慢性刺激等原因有一定关系。这类皮损可以通过二氧化碳激光、电灼，或多次重复液氮冷冻治疗的方式改善。
5. 还有一些存在时间比较短暂的“脂肪粒”，其实本身就是一些闭合性粉刺，也就是早期的痘痘，或者面部毛周角化症的表现。可以通过果酸剥脱、外用水杨酸制剂、外用或口服维A酸类药物使之清除。
6. 靠近鼻子特别密密麻麻而小的“脂肪粒”有时并不是一种异常，而是凸出于皮肤的毛囊皮脂腺单位。这种情况不需要任何治疗，如果觉得不好看，做一些化妆修饰即可。
大体看来，对于真正持久的“脂肪粒”，液氮冷冻的适应症最广，而且遗留瘢痕的风险较低，痛苦也最小；但对于某些较为深在的“脂肪粒”，可能无法起到有效的作用，并且对部分敏感或色素性皮肤的人群尚有遗留局部色素沉着等色素改变的风险。因此，在每个人看来简简单单的脂肪粒，对于皮肤科医师来说，还是需要望闻问切🤣四诊合参，甚至需要进行一个无创的皮肤镜检查来帮助区别，从而替你选择一个最安全而有效的去除方式。

希克苏鲁伯陨石坑
K-T 界線（K-T boundary）
大約在6600萬年前，一顆小行星撞擊在現今的墨西哥尤加敦半島，撞出了直徑180公里，地球最大隕石坑，稱為希克蘇魯伯隕石坑。
劇烈的撞擊引起火山運動，地震，海嘯，隕石撞擊的揚塵瞬間包覆整個地球，暗無天日引起氣候的變化，一連串的連鎖反應，導致地球史上的「第五次大滅絕」事件，非鳥恐龍等生物滅絕，白堊紀宣告結束，新生代古近紀開始，哺乳動物沒了天敵，形成現在的生物多樣性。
當時小行星撞地球，劇烈撞擊氣化後的揚塵中含有大量來自外太空才有的銥金屬，逐漸沉積在地表，這些銥金屬就被發現在K-T 界線的黏土層裏。
我身旁這一整條黑色的帶狀沈積，就是K-T 界線（K-T boundary），在K-T下面的岩層會發現白堊紀晚期的暴龍，三角龍，鴨嘴龍等，在K-T上層找到的多是新生代的哺乳動物和未滅絕的鱷魚或鳥類等。

Difference between parents China parents and the United States parents difference
Americans do not raise children for age protection. Children are self-reliant at the age of 18. Legally, parents do not continue to support the responsibility of children over the age of 18. Children go to college after graduating from high school. Most college students work for themselves or borrow money to go to college. . American parents do not expect children to invite them to live together and take care of them when they are old; instead, they think that independence, taking care of themselves, not bringing trouble to children, and stressing children is the most dignity.

How much power does the United States have for internal disturbances?
James Komi, the former head of the FBI, has violently criticized President Trump in his new book. He also accused Trump of "treating women as if they were treating a piece of meat." He continued to cast various lies and tried to convince Americans, and then came to the conclusion that "Trump is not morally suitable to serve as president of the United States." Trump was constantly attacked by his personal conduct. The number of such attacks and their scale are unprecedented among all the presidents of the United States. Many people believe that this has caused trouble for Trump to perform his duties. The United States’ federal administration system is still able to “normally operate”. This should be considered a unique scene in the United States. At this time, it should not be the period of expansion of the foreign strategy of the United States as a whole, but rather it should be its "seeking period for stability". The Trump administration has always been aggressive, but it is likely that it does not really intend to carry out a sharp collision with external forces that will burden the United States with pain because it lacks domestic unity to do so. It is probably more willing to make relatively easy victories and try to win in all directions without fighting or fighting.

Ischemic heart disease, or coronary artery disease
Although it is still the main cause of death, mortality has declined in many European countries and the United States. This may be due to better public health education, access to health care and forms of prevention. However, in many developing countries, the death toll in Canada is rising. Life expectancy, socio-economic changes and lifestyle risk factors play a role in this increase.
Risk factors and prevention
CAD risk factors include:
hypertension
High cholesterol
smokes
Family history of CAD
diabetes
overweight
Talk to your doctor if you have one or more of these risk factors.
You can prevent CAD with medications and by maintaining good heart health.
Some steps you can take to decrease your risk include:
exercising
regularly
maintaining a healthy weight2018年4月15日星期日
The relationship between oral cancer and HPV virus:What should we do? What should we know?
When you hear about the increasing incidence of HPV, you might think of cervical cancer. So you might be surprised to find that this sexually transmitted virus is also the main cause of pharyngeal cancer (oropharyngeal cancer), and is transmitted between people through oral sex.
Although oral cancer has always been associated with smoking, head and neck surgeon Brandon Prendes says current research shows that HPV is directly related to certain laryngeal cancers. In fact, these cancers are on the rise and will soon overtake new cases of cervical cancer, he said.
According to the centers for disease control and prevention, new cases of laryngeal cancer diagnosed annually may be related to HPV. About 7% of adults have oral HPV, but only about 1% have specific types associated with throat cancer: HPV16.
What are the risks?
The number one risk for oral HPV infection and developing HPV associated pharyngeal cancer is multiple oral sex partners, says Dr Prendes. Having more partners increases the risk for both men and women.
The researchers say women have fewer throat cancers associated with HPV because they may have developed an immune response against cervical cancer. Men don't have the same immunity.
Smoking also increases risk, Dr. Prendes said. If you smoke at least a pack a day for 10 years, you are at your greatest risk.
How do you limit your risks?
Here are five ways to help you limit your risk of HPV-related throat cancer, according to Dr. Prendes.
Limit number of lifetime sexual partners. The increase in risk involved with greater numbers of sexual partners is even greater for oral sexual partners. Also, use condoms or dental dams consistently for some protection.Get children and young adults vaccinated. For males and females between ages 9 and 26, a three-round HPV vaccine can ward off HPV infection.Get screened. Regular screening increases the chances you’ll catch a tumor early. Your doctor will feel your neck, examine your throat and inspect your mouth.Visit your dentist. Get regular dental checkups because dentists are often the first practitioners to notice abnormalities with the tongue and tonsils.Limit smoking and alcohol. Quit smoking and reduce alcohol consumption to cut your risk.
What symptoms should you watch for?
The symptoms of HPV-related throat cancer symptoms can often go largely, Dr. Prendes says, because they're difficult to recognize and categorize. If any of the symptoms lasts beyond two weeks, see your doctor or an ear, nose and throat specialist.
Neck mass or swellingEar pain (like something is stuck in the back of your throat)Snoring (as a new issue, without sudden weight gain)
HPV oral is slow to develop, but quick to spread.
HPV - related working spread quickly to the lymph nodes. It 's not that the tumors spread quickly due to issues with the immune system - they spread quickly for unknown. Having clear that they show up first as large swollen lymph nodes because the body has an immune response at the site of the lymph nodes once tumor reaches this area, causing swelling and a noticeable neck mass, Dr. Prendes says. So, these working are, diagnosed in advanced stages.
It can take up to 30 years for HPV-related throat cancer to appear, making It most common in adults between the ages of 40 and 60. The Oral cancer Foundation reports It's growing fastest among men, ages 25 to 55.
Dr. Prendes says researchers have developed a clinical test that searches for the P16 molecular marker in biopsy samples, a marker that indicates HPV-related cancer. Successful treatment and cure rates are high if you know what to look for and know your risk, he says.
Overall, HPV-related injuries are well to surgery and radiation. Between 90 and 95 percent of cases have five-year, disease-free survivorship rates, he says.
Although researchers are still learning more about HPV-related throat cancer, the verdict about whether HPV is truly to blame is in, Dr. Prendes says.
"I don't think anyone in our field or any epidemiologist would argue the link between HPV and throat cancer at this point," he says.

Target antitumor drugs.
Targeted anti-tumor drugs are mostly tyrosine kinase inhibitors, mainly by imatini, both inside and outside the body. At the cellular level, it is possible to optionally inhibit the positive cell line cells phmyocytic lymphoblastic and acute lymphoblastic leukemia patients. Proliferation and apoptosis of fresh cells. In addition, imatini can inhibit the cell behavior of the growth factor, receptor stem cell factor, tyrosine kinase, and thus the growth factor and stem cell behavior. However, in the course of imatini's treatment, some patients gradually discovered that resistance to imatini was developed, mainly because of the mutation of the gene that expresses the abodase in these patients. A change in the amino acid of the lkinase that results in a change in the structure of the interaction between imatini and the genes on one side.In response to such drug resistance, a second generation kinase inhibitor was developed, such as dastatini, for the treatment of non-small cell lung cancer, selective epidermal growth factor receptor and tyrosine kinase, Efficient oral communication, reasonable expression of growth factor receptor tyrosine kinase inhibitor, etrodandrotiini and use of treatment and for treatment, Multiple targets for metastasis of cancer cells or for mesomesenchymal tumors of the intestinal tract tolerant of imatini to a distance of three levels of uninhibitors.The multi-target therapy for advanced renal cell carcinoma is the Anshan kinase inhibitor, which is a new oral type of empty tumor drug that acts on many chickens and no eight percent. On the one hand, by a 2F segment kinase activity, the signal conduction path is blocked, and the tumor proliferation is directly induced and suppressed. On the other hand, vascular endothelial growth factor receptor has always needed to activate receptor tyrosine kinase, inhibit tumor angiogenesis, and firmly inhibit tumor growth.The right soil of the five high hb receptor has been used as a supplement to antitumor treatment. The structure of the dansk jopalolos joazazza Joaquin drugs is characterized by the structure of both the cecar money or its electrons in an equal row leading to the group ester. Most of the paper miscellaneous links are more complex, usually connected to the desquamate, similar Handan and Korean double rings.

Prediction of drug interactions.
The combination drug is the conventional method of clinical drug treatment，The purpose is to improve the efficacy, reduce the toxicity, but the combination of drugs without purpose can not improve the efficacy, but increase the incidence of adverse drug reactions.Moreover, the incidence of adverse drug reactions may increase and increase with the types of drugs used.In conjunction with drugs, efforts should be made to avoid adverse drug interactions that reduce efficacy or increase toxicity.In order to effectively predict adverse drug interactions, drug researchers are required to carry out screening and early detection during the development of new drugs and the possible drug interactions.Reduce the risk of clinical drugs.On the one hand, clinical medical workers should have a full grasp of the nature of drugs, according to the situation of the disease to carry out a reasonable treatment program.Effective methods of avoiding adverse drug interactions and predicting drug interactions include in vitro camellia, which predicts individual predictions based on in vitro metabolic data.
First, in vitro camellia.
It has become an effective way to determine the future of drug development.Prior to the clinical study, mammal tests were used to screen for drug interactions, but because animals and people do not express or regulate their drug metabolism, There are differences in such areas as results and clinical practice and sometimes there is a big gap.In vitro, the most mature tools for the study of drug metabolism are related to cytochrome P450, a superior family of meta-cap.These enzymes are responsible for the metabolism of most drugs in the body, so the liver tissue slides of liver cells of liver cells of liver cells of liver cells are recombinant and CYP has been used to assess whether candidate drugs can affect the metabolism of another drug.
The second, based on in vitro metabolic data.
It is one of the effective methods for quantitatively predicting drug interactions in the body by using in vitro metabolic data to construct mathematical models.
The method is mainly used for conservative predictions of severe drug interactions, which can eliminate false negative results and maximize drug interactions during drug development.
The third, according to the patient's individual drug interaction prediction.
Be familiar with the basic characteristics of drugs, including drugs, pharmacokinetics and pharmacodynamics, which are very important to predict the clinical drug interactions, and the most obvious types of clinical drug interactions. It's almost a drug called Wu Xiaoqiang, whose medicinal effects are shaking.
For example, the cytotoxic drugs digoxin, warfarin blood sugar.
The safe range of these drugs, the effect of the interaction of small drugs, the concentration of blood drugs outside the treatment window during a period of time, leading to a decline in efficacy or toxicity, Clinical use of drugs should be familiar with the main types of drugs that affect CPR, including the main gifts, inhibitors, luring agents, drug interactions that can occur in a short period of time. Others require treatment for several days or weeks to several weeks.For example, chloramphenicol has a long half-life and it takes several weeks for the effect，If the main management of C9 rabbit C9 metabolism drug treatment may still have no inhibition, resulting in poor clinical results.

Einstein's three big mistakes.
Einstein was also a great man, and of course he would make mistakes, even if he had made mistakes in physics, and Einstein admitted that he would make mistakes. He thought the biggest mistake he had made was to put forward universe constant.General relativity predicts that the universe is either expanding or contracting, when Einstein's theory of relativity, physicists think that the universe is static, in order to solve this contradiction. There is also a cosmic constant in the formula of general relativity.Let the universe become static, and after Hubble discovered that the universe was expanding, regretted it, so he counted the universe as the biggest mistake he had made.
But in recent years, the discovery of Montenegro on this issue may not be so big, after the initial big bang, the universe has been expanding, but the gravity of the matter that is distributed in the universe. It will also try to pull the universe back, by the influence of gravity, in theory, that the expansion of the universe should be slower and slower, and astronomers predict the supernova.How much of the expansion of the universe has slowed down in the past billions of years? The result is unexpected, the expansion of the universe not only has not been reduced, but is accelerating, which means that there is some unknown mysterious energy in the universe, called dark energy to counteract the role of gravity.
This will allow the universe to expand faster and faster, and some physicists think that the universe should always be counted at home, and let him express dark energy, if that is the case. Einstein is right in a way.
Einstein thought he was wrong, and he did not think he was right about his criticism of quantum mechanics, though he believed he was right, but now it seems likely to be wrong. Because of the study of the photoelectric effect, Einstein was regarded as one of the fathers of quantum.But he thinks that quantum mechanics is correct, but not complete, there must be unknown factors that can explain the observable quantum phenomenon, in order to find the loopholes of quantum mechanics. Einstein put forward some thought experiments, and most of them could not stand the sale, but one of the most famous thought experiments was impeccable. This thought experiment 33 boduoersiji Rosen published a paper in '1935, physics is real, and quantum mechanics describes being completely blown up.This important paper was later written under the initials of the three masterpieces.

Guo Moruo and Li Ao.
The death of Mr. Li Ao, on the Internet set off a fierce battle, overall, aversion and disdain to be more.I think this is a kind of humanistic progress, but also the progress of a kind of thought.
But I have found that there are a lot of people who are doing it for you, and you can't justify it.
Some people say that you have to fight against the power of the past, and strive for freedom, the works, and so on, can not deny this person.
You're right. I'm not denying it. This is the kind of man.I despise him.
So our comparison, Guo guomoruo, brother, he was also anti-totalitarian in his early years, true freedom, brother and Liao, all called Chiang Kai-shek, called the United States, praised the leader, and praised the dictatorship of the Brother is the same person, praise is from the heart, although the late writing is too bad, too disgusting, but the same group of people sing the song, think and understand, and you are an anti-dictatorship fighter. Why did the later self-brainwashing become a totalitarian advocate?
It was not a total denial, but Guo's defense against you, they are not a matter of essence, early to 19, when asked about the voice of the stretch marks.
Because I see you are not as good as Guo guomoruo, Guo guomoruo wrote 20 scripts in his life, only three rebellious women, 3 sentences and four seasons, can lay the status of a writer. The theme of the four seasons is the anti-tyranny, the anti-totalitarian, the work of freedom and justice, is for your good, what kind of work can be taken out, Beijing fayuansi, It's a terrible thing.The first master of the vernacular is self-blown.80 pieces of work can only be one person, as a writer can not be based on a lot of people can become a writer, but can not become a writer, Liao is one.If you want to be Unicom, it's one of the 400 of the mainland. Why do you want to face it?
A bird's life is only in Taiwan, the mainland of Hong Kong, aging and not going to the United States, Japan and Europe, so how can a person know the world?
He wrote articles, yinjingjudian, pang, Lishi, Lishi, Xue, Dan,,,,,,,,,,,,,,,,, In addition to his experience, to him is a kind of revenge psychological time, revenge pleasure.
Ma, the third or the curse, then the social and the trance of the times is out of touch with him, and also to say that the right of home and her relationship belongs to the modern case. I can't see that the daughter is a few authors living in the real world, he is living in the artistic conception, a person, the teacher's opinion is not an artistic conception.
So you should always know the history, but do not understand the reality, if you understand Taiwan, but do not know the world.
He is in a democratic society, and not only is he so servile.
I am absolutely in favor of chairman Liu Yuan's assessment of Mr. Liao, which means his later years.
Liaowannian, where the environment is more safe than Guo guomoruo in his later years, with a lot of flattery, he wrote a lot of nausea and praise, because of the lack of face in the system, it is understandable. In the open and democratic environment, the basic long or the more standard, the flattery to make money, which is more inexcusable.
Some people have wanted to stand up for the present, Lu Xun is not ungrateful, and think that the toxicity is far worse than the cattle, he is my first flower this year, Lu Xun's 15, the last time it was that Liao style 1 changed, began to attack Lu Xun, Lu Xun said that the Chinese people how to go today, never naming names who are not naming names, the bad government at that time.
From this point of view, you and the person who is known as reading the book, did not seriously read Lu Xun's works, the dragonfly to look at the water and not read, many people's books are not clear, name For example, the road to the mainland, Milan and the time to go to Taiwan and is a constant, is the direct report of Qiu Dongcheng, but also named names of the government, such as the northern army government, The government, the Kuomintang's national government, took a little time to look at the complete works of Lu Xun.
The most admire of Liao's life is Hu Shi.In the past, I like to be good, but also because he is proud of his relationship with Hu Shi, which is worth showing off, but the life of flint, in addition to the study of learning, Most of the time is calling for a free and tolerant social space, the universal value of democratic rule of law.What did Grio do again? When he came out of prison, especially after Hong Kong and the mainland, did he elaborate on the universal value?Have you ever called for democracy?In the first half of his life you have some Lu Xun's style of writing and Hu Shi's rationality, Lu Xun's calmness of life and the passion for the world, you have to learn a bit of fur in the.If you stick to it, you can have the essence of two people and people.Unfortunately, the daughter later from the fundamental disdain of Lu Xun, to be consciously away from the sense of consciousness, but gradually gradually from the spiritual level of Guo guomoruo, although he laughed at Guo guomoruo, But it never occurred to him that he would become Guo guomoruo.

Science and fairy tales.
I talked to my daughter a few days ago, and my daughter told me that people often asked him about his father's profession. She often replied that it was a complicated problem. My father was a full-time father and His sideline is making money.
Indeed, I love children so much, so I care most about the books that children love to read, but sometimes you pick the whole library, and you can't find a few books for children to read. My parents like to buy green fairy tales, 1001 nights and so on, 70 parents have not read them, or have not read these books carefully. It is said that there are a lot of stories that do not belong to the little princess, so I often only give children three sisters and self-made stories.
Now some authors have a little reputation.Like shoddy television, the establishment of a studio, a dozen or even dozens of books a year.Put their fame like pork on a stall, for people to consume.And I don't care about the quality of the book until I get my name dry.
There is a book called detective owl, which satisfies all my demands on fairy tales, first of all, and this is the group of children who read and read. The Xiao Wu I know is almost all at once reading a book of words, and then it is not enough to ask where the second book is? Second, the characters are alive.The witty brave Mai, the intelligent beautiful 20 holes, the brave and fearless little ash to the unicorn ghost meat ball, the insidious cunning long tail.
Perhaps one day, these images can become familiar to the children, the third is knowledge-rich, I was worried that such a word of the fairy tale is not to eat too much. Almost every piece of the author's infinite effort, not only to let the story flow, but also to keep the knowledge and the story seamless, so that children in the interest of reading to understand the science.My son told me, don't worry, don't understand, remember not to look at the second time, this is a detective fairy tale, all the knowledge of the ignorant, a detective story. The key to insecurity is science, combining science with culture.The fourth is from the book that the author is a firm environmentalist.Through a story, the author of the earth's hardship, the view of environmental protection, there is a new perspective in front of the little girl, the simple protection of no scientific method. The same is the destruction of the environment, in order to protect the forest, the ranger has taken the initiative to set fire to the whistle.Majing, the giraffe, and other networks reveal that simple persuasion is environmentally friendly, and without scientific methods, the individual brings more thinking. It was also the reason why I thought about the secret science and fairy tales of the late day.
The loss of life, the water is a wonderful little story, so that children know the nature of all kinds of animals to survive the survival of a set of water-saving skills.
We have always wondered, how do animals in the city of commerce save water?
Even worried that they will often die of thirst for the story, give the children a good answer to this question, the corner big antelope can not drink 1 drop of water in 10 months, almost no water, Millet paste does not need to drink water, and thieves eat their own feces, 2 times to absorb their own moisture, and almost do not drink water, the little kangaroo rely on their own water cycle system and do not have to drink water, I think it's wonderful to see it everywhere.
I hear a lot of children see, inspector owl consciously wash his hands, pay attention to hygiene that is the story of a lot of the mysteries of death abroad, the author used to explore the mystery of the death of a large number of of To explain the life history of the gongxingchong is the necessity and science of the children to wash their hands after the meal.
Huang Guangying huochong are written to us adults, and now most of the children can only see fireflies on TV, and when we were young, we were the love of fireflies. We have been chasing fireflies all summer, and we have never thought about the beautiful story behind the fireflies, remembering childhood, which is a kind of shame.
The son was curious about Harvey's life.I couldn't talk to him about a royal bloodline, and I cured her wings with a common method of martial arts.But I prefer a, who is a storyteller, and you can have a Cinderella friend or a civilian hero.
The second edition of this book is about to come out. Let's look forward to it. It must be more exciting.

An awful bacterium may exacerbate colon growth.
Streptococcus gallolyticus prodded development of some colon growth cells in lab dishes and in mice, specialists report July 13 in PLOS Pathogens. S. gallolyticus fortifies a biochemical chain response that researchers definitely knew is engaged with the improvement of colon malignancy, the specialists found.
Microscopic organisms must be in guide contact with tumor cells to speed development, yet precisely how the microbes do that isn't yet known. Encourage examination could enable specialists to discover approaches to hinder the microorganism's activity, prompting better medicines for colorectal growth, says microbiologist Yi Xu of Texas A&M University Health Science Center in Houston.
Individuals who have heart valve or blood contaminations of S. gallolyticus (already known as S. bovis) regularly likewise have colorectal tumors. The bacterium has additionally been discovered developing on tumors in some colorectal growth patients. In any case, specialists couldn't tell from affiliation thinks about whether the microscopic organisms were egging on tumors or were guiltless spectators.
Xu and partners developed S. gallolyticus in lab dishes with a few unique sorts of human cells. Three sorts of colon tumor cells became quicker, delivering around 50 to 60 percent more cells inside 24 hours, with the microorganisms than they did when refined without any microscopic organisms or with an innocuous, drain maturing bacterium called Lactococcus lactis. Typical human colon cells, kidney cells, lung disease cells and two strains of colon growth cells didn't react to the microscopic organisms. Those outcomes could imply that the bacterium doesn't goad on all colon malignancies, says Cynthia Sears, an irresistible malady expert at Johns Hopkins University School of Medicine who was not associated with the work. Discovering what makes a few cells more defenseless against the microscopic organisms will be essential for future investigations, she says.
"It merits a more profound look," Sears says.
Colon cancer‒prone mice contaminated with S. gallolyticus had more and greater tumors than those found in mice immunized with L. lactis or with a saline arrangement.
Xu and associates don't have a clue about every one of the points of interest of how S. gallolyticus advances colon tumor development. However, the scientists found that when the microorganisms glom onto responsive colon disease cells, the organisms help a flag sent through a transfer chain known as the beta-catenin pathway. That pathway was at that point known to be associated with creating colorectal tumors. The analysts have some confirmation that S. gallolyticus may likewise work through other substance flagging pathways to improve colon malignancy development.
Regardless of whether the bacterium can start colon malignancy isn't clear, Xu says.
Analysts will likewise need to research how S. gallolyticus works with or against different microorganisms that live in the colon, says Ran Blekhman, a geneticist at the University of Minnesota in Minneapolis. The investigation is a piece of a developing pattern far from just associational examinations toward finding how organisms work in the body, he says. "This is fundamentally the subsequent stage in microbiome examine."
