Researchers from the Abramson Cancer Center at the University of Pennsylvania claim to know why cancer most often spreads to the liver. Liver cancer is a leading cause of death in the United States and scientists had been hard put to understand it for a long time. The researchers published their findings in the journal Nature.

Hepatocytes are the main operative cells of the liver. The researchers found these liver cells are vulnerable to cancer cells as a result of a complex chain of organic events. The IL-6 signal drives the chain reaction that enables cancer cells to invade the liver.

A Chain Reaction with Liver Cells and Complex Proteins Causes Liver Cancer

When this chain reaction is set in motion, it inflames the hepatocytes which in turn activates the production of the protein STAT3. With the inflammation of liver cells and the subsequent production of STAT3, other proteins known as SAA rise to the surface. In the presence of inflammed hepatocytes, proteins STAT3 and SAA, the liver undergoes a process which enables cancer cells to move in and take root.

The researchers were able to demonstrate that releasing antibodies to block the activity of the IL-6 inflammatory chain-reacting signal can make it impossible for cancer cells to spread to the liver. Assistant professor of Hematology-Oncology at Penn’s Perelman School of Medicine Gregory L. Beatty, said hepatocytes are at the center of the liver cancer risk. Beatty is the senior author of the study.

The authors of the study conducted their research on mice. They discovered that hepatocytes in mice having cancer activated STAT3, but this is never the case in mice without cancer.

Restrictive Therapies on Hepatocytes Can Prevent Cancer from Infecting the Liver

Collaborating with scientists from Mayo Clinic Arizona, the Penn researchers found that people with pancreatic, colon and lung cancers undergo the same phenomenon – their hepatocytes indicated STAT3 activation. When STAT3 in the hepatocytes of lab mice was effectively removed, their liver became less vulnerable to cancer infection.

With further interactions with investigators from the University of Kentucky, the research team proved that IL-6 signals STAT3 to inflame hepatocytes, an action that produces SAA to ultimately make the liver attractive to spreading cancer cells.

Furthermore, it was demonstrated that with or without cancer tumors, any increase in IL-6 levels propels changes that make the liver susceptible to inflammatory cancer cells. Factors that could cause a spike in IL-6 level include obesity and cardiovascular diseases. To this extent, medical therapies on hepatocytes can prevent cancer cells from reaching the liver, effectively preventing liver cancer and cancer-related deaths.

With a report from a statement released by the Parana state government, the state authorities shut the unnamed operation and ended up arresting nine people.  

 

The statement reads that it became evident that the operation was a swindle when the victims obtained a message in the company telling them they will not be able to draw their money.  

The justification provided by the company was that it incurred a loss of about $4.8 million to a conman. But six months, after the stated, the frauds further delayed the withdrawal period .

One of the conned folks stated that the company had assured they would get daily returns of 4 or 3 percent on the money they had invested. The fraudsters targeted victims through media.  

The are currently charged with money laundering swindle, criminal association, and forgery.

SpaceX has lighted up the Falcon 9 rocket, which will carry the next payload of the thing on a task to space the week.  

The experiment took place at Space Launch Complex 40 at Cape Canaveral Air Force Station ahead of its scheduled send off on December 4.

At 5:30 p.m. EST (2230 GMT), the Falcon 9 rocket came into life. Smoke rose during the prelaunch test in the motors. The test also referred to as a evaluation is among the last milestones that were and a main part of procedures before the launch.

They maintain the spaceship and temporarily fire its nine engines. The firing enables crews to ensure that each system is correctly working and the spaceship is prepared to go. Briefly, following the evaluation, SpaceX posted in their official Twitter page the static fire was successful and that the company was planning to start on December 4 at 12:51 pm EST (1751GMT).

SpaceX representatives wrote on an update that Falcon 9 static fire test finishes aiming December 4 liftoff from pad 40

New Shepard launch

On December 11 2019, New Shepard vehicles lifted NS-12 Suborbital mission. This was the 1st flight in more than seven months and it is inching close to developing flight that will ferry people to the  lower part the of space

This New Shepard launch took place at 12:53 PM Texas time, this was delayed due to bad atmospheric condition and in 10 minutes, the flight had reached a height of 104.5 kilometers whereby the vehicle propulsion module and the crew capsule landed separately and peaceful.

This type of flight was the 6th one where the propulsion and the crew capsule land separately which is the best record for the company.  Another New Shepard propulsion module flew five missions before it worn out and now is used in a series of flights.

New Shepard payloads include NASA experiments, which were eight in number to determine the chances of flights to access to suborbital vehicles. The other experiments came from the University of Florida, which aimed at studying the gene expression on plants
