New Delhi, October 25, 2017 : A 30-year-old woman was shot dead in the early hours of Wednesday in front of her husband and two-year-old son, police said.
Deputy Commissioner of Police Milind Mahadeo Dumbere told IANS the woman, Priya Mehra, was travelling in a car along with her husband and son when she was shot at around 4.30 a.m. in Shalimar Bagh in north-west Delhi.
Her husband told police he had borrowed money from someone and alleged the lender was behind the killing as he was unable to pay the amount back.
He had borrowed Rs 5 lakh in a high interest rate and as the debt grew into Rs 40 lakh, he was finding it difficult to pay back.
“There were four assailants in a car, according to the deceased’s husband, and she was shot at twice,” the police officer said.
Dumbere said no one has been arrested yet and the body has been sent to Babu Jagjivan Ram Memorial Hospital (BJRM) Hospital for autopsy.
The family was on the way to their house in Rohini from Kashmere Gate, when the woman was murdered. (IANS)
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.
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.
