Chinese scientists develop new chemical method for stem cell creation

A team of Chinese scientists is currently developing a chemical method for stem cell creation that will help cure life-threatening illnesses sooner than most people think, at the Guangzhou Institute of Biomedicine and Health (GIBH) in south China.

Stem cells might be the most powerful cells in the human body. When harvested and reinjected into humans, they help regrow and regenerate cells that were damaged or lost due to illness and injury.

“We extract some cells from a patient, then convert them into stem cells which can grow a new organ,” said Li Dongwei, lead researcher at the GIHB.

Experts said they now have a way to create stem cells in a lab.

“The best way is to use chemicals. All you have to do is just culture the cells in different culture media, and hopefully, you can accomplish the same feat,” said Dr. Pei Duanqing, director of the GIHB.

That feat is converting somatic cells, virtually any cell in an adult body, into pluripotent stem cells, the type that can be used in a multitude of ways. The older, less functional cells are soaked in a cocktail of 10 different chemicals, which converts them into valuable stem cells.

According to Pei, past stem cell creation methods involved experiments using viruses, but the chemical method is much more practical. People should be consuming Vitamin C, one of the substances in the cocktail regularly, he added.

For years now, scientists in labs like the one in Guangzhou have been able to turn back the clock on somatic cells with the help of stem cell experiments.

“That’s a whole new science of human physiology that we have to work with. And I think that’s far more complicated, and that will require further investment and also careful planning,” said Pei.

The team said trying their current approach in humans could trigger serious side effects, like cancer, but by continuing the research, they will develop safer methods for stem cell treatments, which will become affordable for the average patient in the future. — Reuters

Xi Jinping, general secretary of the Central Committee of the Communist Party of China (CPC) and Chinese president, held talks with Kim Jong Un, chairman of the Workers’ Party of Korea (WPK) and chairman of the State Affairs Commission of the Democratic People’s Republic of Korea (DPRK), in Beijing on Tuesday.

The two leaders had a candid and in-depth exchange of views on the current development of China-DPRK relations and the situation on the Korean Peninsula.

They agreed to safeguard, consolidate and develop China-DPRK relations, and jointly push forward the sound momentum of peace and stability of the Korean Peninsula to make a positive contribution to safeguarding world and regional peace, stability, prosperity, and development.

Xi said that China was pleased to see the important summit between Comrade Chairman and U.S. President Donald Trump in Singapore achieve principled consensus and positive results in realizing the denuclearization of the Korean Peninsula and establishing a lasting peace mechanism on the Peninsula. — Reuters

Chinese scientists make breakthrough in nano technology

Chinese scientists have recently made a breakthrough in nanotechnology research, injecting new momentum into new energy and material development in China.

A news conference was held by Chinese Academy of Sciences (CAS) on Wednesday to announce the significant results of the nano research special project which was launched five years ago.

The all-solid-state lithium-ion battery developed by the project can provide a stable supply of electricity to the deep-sea research of the Mariana Trench with a single maximum power supply time of 20 hours. This breakthrough indicates that China has mastered the core technology of 10,000-meter power supply. It also lays a solid foundation of energy supply for deep-sea space station experiment.

“We have done more than 1,000 cycles of third-party testing. In security testing, we have adopted a stricter testing standard than the power batteries, and they all passed the test. So we think this will be a very important technology for the future,” said Li Hong, a researcher at Institute of Physics, CAS.

After five years of hard work, Chinese researchers have made a major breakthrough in basic studies and turned their results in research into mass production and industrial applications. A series of nano-core technology innovation has been achieved in power lithium-ion batteries, green printing, nano-catalysis, health care, drinking water treatment and other industries. The technology breakthrough has provided a strong support for China’s new energy, new materials and other emerging industries of strategic importance.

“We have now played a leading role in formulating two international standards. We have six others which are in the process of further improvement. We also have more than 30 national standards. They cover the standards of testing high-energy-density power batteries. The promulgation of these standards worldwide will provide a reference for the manufacturing of these products by our peers in other countries, and at the same time help our products to get access to the international market,” said Wang Chen, principal investigator of the nano special project. — Reuters

PH asked China to stop seizure of Filipino’s fish catch, discipline its coast guard – Malacañang

Secretary Harry Roque with three of the fishermen who had encounters with the Chinese coast guard

 

MANILA, Philippines – Presidential Spokesperson Secretary Harry Roque assured Monday, June 11, that the government has already asked China to stop its coast guard personnel from taking the fish catch of Filipino fishermen in Scarborough Shoal.

At Malacañang, Roque presented before members of the press some of the fishermen who had encounters with the Chinese coast guard. They narrated that the Chinese would barge into their vessel and seize their catch. Since they do not know their language, the fishermen would just let them proceed to avoid tension. The Chinese men would give them some noodles and drinking water in return, and leave.

“Sila na po mismo ang aakyat. Tapos hahalungkatin iyong lagayan ng isda. Di naman kami magkakaintidihan sa pag-uusap kaya kumbaga, nakikisama na lang kami kasi baka nga paalisin na naman kami,” narrated Romel Cejuela, a fisherman from Baja Masinloc, Zambales.

Malacañang does not consider it as harassment because there was no force involved and neither party used a weapon. However, the fishermen are asking the government to take action to prevent a repeat of the incident because it affects their livelihood. In fact, the Chinese have been taking at least P4,000 worth of their income.

Roque said the government has taken steps on the matter, citing that President Rodrigo Duterte and Chinese President Xi Jinping had agreed to ensure freedom of Filipino fishermen to fish in the waters of Scarborough Shoal.

“Gumawa na kami ng mga hakbang, at ang hinihingi natin dapat gumalaw ang mga otoridad ng Tsina na itigil itong mga pangyayari. So kinakailangan, disiplinahin siguro ng Tsina yung mga bugok na nangunguha ng isda,” Roque said.

However, if they were to be asked, local fishermen would prefer that Philippine Coast Guard or Navy personnel should withdraw their presence in Scarborough Shoal to avoid the tension from further escalating.

“Siguro ok na muna siguro yun [walang coastguard]habang patuloy munang nag-uusap yung gobyerno ng Pilipinas at China para maayos yung mga dapat ayusin siguro,” added Cejuela.

“Mula po ng panahon na pinadala ni Presidente Aquino ang (BRP) Del Pilar diyan sa Scarborough, di na po tayo nakabalik na tayo ang may control (diyan.) Ngayon po, totoo po na nandoon ang mga Tsino pero nakakapangisda po ang mga mangingisda ng Masinloc at ibang mga lugar,” Roque said in agreement to the fishermen’s proposal. – Rosalie Coz / Marje Pelayo
