When it rains, open your umbrella.
You and I are passers-by.
Walk on the edge of September,
at this moment,you come from the heaven
next second you cross the river from the bridge.
I have been a river in your life,over there,you and I have loved
never seen the dark
Summer told me to forget
Autumn let me give up
But I always remember the feeling of rain passing through the palm of my hand
When it rains,you don't want to run,you have the sky
you have the stars that you can't see before.
When it rains,use a glass of red wine to protect the color of the blood,and then with the stubborn faceof an umbrella to be forgotten in the eyes,
is overestimated the night

An awful bacterium may exacerbate colon growth.
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."
