BioDiscovery will pay attention to the "medicine" smell with you and explore the value of biotechnology!

01 New anti-cancer technology may cure advanced cancer

Recently, researchers at Yale University and the University of Rhode Island have made new discoveries
about the treatment of advanced cancer.
In the experiment, the researchers administered a combined injection method
to 20 mice with small colon tumors.
In the case of only a single dose, 18 of the 20 mice participating in the experiment had small colon tumors that disappeared completely, and even developed immune memories
of cancer.
When the cancer cells were injected again into the cured mice, no new tumors appeared
during the 60-day observation period.
The study has been published in
the journal Frontiers in Oncology.

02 Scientists successfully cultivated hair follicles in vitro

Recently, according to the journal Science Progress, a team of researchers from Japan studied the process of hair follicle growth and hair pigmentation, and successfully produced hair follicles
in culture.
Their in vitro hair follicle model increases understanding of hair follicle development and helps develop applications
in the treatment of hair loss diseases, animal testing, and drug screening.

The organoid culture system developed by the research team generates hair follicles and hair shafts
almost 100% efficiently.
Hair follicle organoids produce fully mature hair follicles with long hair shafts that are about 3 mm
long at 23 days of culture.
As this growth occurs, researchers can monitor hair follicle morphogenesis and hair pigmentation in vitro and understand the signaling pathways
involved in this process.

The researchers investigated the feasibility
of hair follicle organoids for drug screening and regenerative medicine.
They added to the medium a drug that stimulates melanocytes, which plays a key role
in the production of hair color pigment.
With the addition of the drug, the pigmentation of hair fibers improved significantly
.
In addition, effective follicle regeneration
is achieved through repeated hair cycles.

03 New Korean technology can synthesize artificial bone in large quantities

Recently, a research team from the Korea Academy of Science and Technology announced that they have developed a synthesis process technology that uses a laser to create an artificial bone meal hydroxyapatite
in tens of seconds.

This process is to add calcium and phosphorus to water and heat it for a long time to make artificial bone meal, which takes a minimum of 20 hours and a maximum of more than 100 hours
.
The team synthesized powders of various sizes within 10 minutes
by irradiating a laser into the solution.
Among them, by replacing part of the calcium with magnesium or zinc, and it can also be made into bone meal
with antibacterial and tissue regeneration effects.

Bone meal made by this process is expected to be used in bone graft materials
such as dental implants.
It is also expected to lead the way in technology to make fillers
that can synthesize collagen in the skin.
"From a technical point of view, there is no difficulty in commercializing it immediately, but the barriers to equipping it to clinical processes and large-scale production facilities remain," the researchers said

04 State Food and Drug Administration: Ensure the quality and safety of online drug sales

On October 20, Huang Guo, deputy director of the State Food and Drug Administration, led a team in Beijing to investigate the preparations for the implementation of the Measures for the Supervision and Administration of Online Sales of Drugs, and gained an in-depth understanding of the implementation of the responsibilities and obligations of platform entities and the strengthening of
business behavior management.

Huang Guo stressed that to publicize the "Measures for the Supervision and Administration of Online Sales of Drugs", Internet platform enterprises are the key
.
Platform enterprises should implement management responsibilities, comprehensively strengthen the quality management of online drug sales, and establish and improve the quality management system; It is necessary to give full play to technical advantages, use the management means of network management network, continue to improve industry standards and service levels, and strive to achieve results in platform ecological governance; It is necessary to strengthen the publicity and training of settled businesses, supervise and guide merchants to operate legally and compliantly, and form a good pattern
of social co-governance.

05 From 2022 to 2025, the country will organize and carry out actions to improve nutrition for the elderly

Recently, in order to further improve the nutritional health of the elderly, the Office of the National Working Committee on Aging issued the Notice on Carrying out Actions to Improve Nutrition for the Elderly, deciding to organize and carry out actions to improve nutrition for the elderly nationwide from 2022 to 2025
.
The actions mainly include four contents
: publicizing nutrition and health knowledge for the elderly, strengthening nutrition intervention for the elderly, improving the nutrition and health service capacity of the elderly, and carrying out public welfare activities for the nutrition and health of the elderly.
