Using a high-resolution 3D printing process, Austrian researchers have succeeded in creating an artificial placenta barrier on a chip, a development that can be used to investigate important aspects of nutrient transport from the mother to the foetus.

The placenta ensures the exchange of important substances between the mother and her unborn child, whilst simultaneously blocking other substances from passing through.


“The transport of substances through biological membranes plays an important role in various areas of medicine,” said Aleksandr Ovsianikov, professor at the TU Wien university in Vienna.

“These include the blood-brain barrier, ingestion of food in the stomach and intestine, and also the placenta.”

Studies have shown that diseases such as diabetes and high blood pressure in the mother can affect the transport of substances to the foetus. Until now however, it has been almost impossible to investigate the way in which the many parameters involved interact in such cases.

Using the 3D printing made it possible to produce customised hydrogel membranes directly within microfluidic chips, which are then populated with placenta cells.

This can help provide clarity on how the exchange of glucose between mother and child takes place, the researchers said.

The novel chip consists of two areas — one represents the foetus, the other the mother. Using a specially developed femtosecond laser-based 3D printing process helped produce a partition between them — the artificial placenta membrane.

The high-resolution 3D printing involved a hydrogel with good biocompatibility.

“Based on the model of the natural placenta, we produce a surface with small, curved villi. The placenta cells can then colonise it, creating a barrier very similar to the natural placenta,” Ovsianikov explained.

Initial tests have already shown that the artificial placenta on the chip does in fact behave in a similar way to a natural placenta: small molecules are allowed to pass through, while large ones are held back, the researchers noted. (IANS)

Rihanna was summoned from her seat to accept the honour, with the Prime Minister.

Singer Rihanna was honoured by Prime Minister Mia Mottley at an event which marked Barbados's new status as a republic, which was attended by Prince Charles. Addressing the pop star by her real name, the PM said: "Robyn Rihanna Fenty tomorrow morning shall have conferred upon her the order of national hero of Barbados."

Rihanna was then summoned from her seat to accept the honor, with the Prime Minister managing to rouse a laugh from the singer when she referenced her 2012 hit 'Diamonds', reports femalefirst.co.uk. She added: "On behalf of a grateful nation, but an even prouder people, we therefore present to you, the designee, for the national hero of Barbados." "And to accept on behalf of a grateful nation - you can come my dear - ambassador Robyn Rihanna Fenty, may you continue to shine like a diamond and bring honor to your nation." Rihanna, who was born in the St Michael parish of Barbados, found fame in 2005 after being spotted by a record producer and has since gone on to become one of the most successful female artists of all time with sales of over 250 million and recently reached billionaire status through her Fenty beauty brand.

The Prime Minister continued in her speech: "Commanding the imagination of the world through the pursuit of excellence, her creativity, her discipline, and above all else, her extraordinary commitment to the land of her birth. "Having satisfied that, Ambassador Robyn Rihanna Fenty has given service to Barbados which has been exemplified by visionary and pioneering leadership, extraordinary achievement and the attaining of the highest excellence to the Government of Barbados." It comes after a historic move for Barbados, which has become a republic after almost 400 years and welcomes its first president, Sandra Mason, after removing Queen Elizabeth as head of state.

Typically, Glaucoma occurs in people with over the age of 60 however it can occur at any age.

By IANSlife

Have you ever faced eye redness? Or have witnessed blurry or foggy vision? Or experiencing halos around lights? Or nausea and vomiting are very common for you. You may well be suffering from Glaucoma which needs immediate attention.

Glaucoma is the second most common causes of blindness worldwide, according to a report by World Health Organisation (WHO). Typically, it occurs in people with over the age of 60 however it can occur at any age. It is also estimated that globally 79.6 million people are affected with glaucoma, half of them being Asian population. While in India, around 11.9 million people suffer vision impairment and out of which 1.2 million cases are due to Glaucoma. It is a growing concern for the population in India. Even after these high numbers, the enormous majority remains undiagnosed, and untreated. More than 90 percent of cases of Glaucoma remain undiagnosed.
