Scientists develop world’s first bioelectronic medicine

Scientists from US claimed that they have developed world’s first bioelectronic medicine which is implantable, biodegradable wireless device that speeds nerve regeneration and improves healing of damaged nerve. The device has not been tested in humans, but its successful testing on animals (rats) offer promise as future therapeutic option for nerve injury patients.

Key Facts

The bioelectronic medicine device is wireless is powered and controlled wirelessly by transmitter outside body that acts much like cellphone-charging mat. It operates for about two weeks before naturally absorbing into the body. It has size of dime and thickness of sheet of paper.

During its animal test on rats with injured sciatic nerves, it was found that this bioelectronic medicine device delivers regular pulses of electricity to damaged peripheral nerves in rats after surgical repair process. This results in accelerating regrowth of nerves in their legs and enhances ultimate recovery of muscle strength and control.

Advantages of Bioelectronic medicine

This biomedical technology provides therapy and treatment over clinically relevant period of time and directly at site where it is needed, thereby reducing side effects or risks associated with conventional, permanent implants. Moreover, these engineered systems provide active, therapeutic function in programmable, dosed format and then naturally disappear into body, without trace.

With this device, it has been shown that electrical stimulation given on scheduled basis during surgery can further enhance nerve recovery. No adverse biological effects from device and its reabsorption were found. Researchers envision that such transient engineered technologies one day can complement or replace pharmaceutical treatments for a variety of medical conditions in humans.

India’s first National Environment Survey to kick off in 2019

India’s first ever National Environment Survey (NES) will be kicked off in January, 2019 to map environment data of 55 districts across 24 states and 3 Union Territories. The NES will rank all districts on their environmental performance and document their best green practices based on various environmental parameters. The earliest first set of complete green data from this survey will be available in 2020.

1st National Environment Survey (NES)

The first NES will be carried out by Ministry of Environment, Forests and Climate Change (MoEFCC) through Environmental Information System (ENVIS) and its hubs and resource partners across the country. It will be done through grid-based approach, using grids measuring 9×9 km to collect comprehensive data on various environmental parameters. These parameters will include air, water, soil quality; solid, hazardous and e-waste; emission inventory; forest & wildlife; flora & fauna; wetlands, lakes, rivers and other water bodies. It will also assess carbon sequestration potential of all the districts across the country.

Significance

The green data from this survey will provide important tool in hands of policy-makers for decision making at all levels – district, state and national. The survey will fully map and create emission inventory, provide valuation of ecosystem services and collate research in the field of environment. Initially the survey will be focusing on 55 districts and later will be scaled up to all districts in the country. The skilled manpower required for the survey will be provided from persons skilled and trained under MoEFCC’s Green Skill Development Programme.
