Biomedical engineers are an important part of the medical community. The knowledge, inventions, and people that are behind many biomedical engineering jobs are responsible for improving lives across the globe by creating new theories on life systems or designing medical instruments.
The contributions made by those employed in biomedical engineering jobs are countless: minuscule devices to inhibit cell growth; artificial bones, tendons, and discs; highly sensitive monitors and medical imaging systems; artificial hearts; synthetic blood; medical robotics; and tissue engineering – to name just a few.
A team of experts at the Yale University has recently announced that it has developed a new series of nanosensors, a class of devices that is able to analyze whole blood samples, and detect the presence of cancer biomarkers in them. The latter are chemical agents that tumors and cancer cells produce, and their existence in the body can only mean one thing. The amazing achievement could soon enable physicians to cut the cancer-detection process short, leaving more time for the actual treatments.
Scientists from University of Strathclyde have devised a novel way to harness natural vitamin E extract that would kill tumours within 10 days.
Using a new delivery system, the research team could mobilise an extract from Vitamin E, known ton have anti-cancer properties, to attack cancerous cells.
In the study conducted over skin cancer, the researchers found that tumours started to shrink within 24 hours and almost vanished in ten days.
They believe the tumours might have been completely destroyed if the tests had continued for longer.
When the tumours regrew, they did so at a far slower rate than previously.
Biomedical microdevices include any miniaturized devices or systems for biomedical or biological applications, from simple sensors for monitoring a single biological, to complex micro total analysis or lab-on-a-chip instruments that integrate multiple laboratory functions together with microfluidic sample manipulation. Biomedical microdevice and systems research is an exciting multi-disciplinary field intersecting engineering, physics, chemistry, nanotechnology and biotechnology.
Micromachining, originally based in the microelectronic industry, forms the foundation for this exciting field, in which biosensors, microchannel fluid transport, and other micro mechanical, optical, chemical, and fluidic components are fabricated and integrated for applications ranging from monitoring biofluid levels and bed side rapid diagnosis to studying single cell antibody production. Furthermore, micromachining can be combined with nanostructures or nanomaterials to result in new technologies and techniques that continue to advance the field in new ways.
The Indo-US Science and Technology Forum (IUSSTF) In association with Science and Engineering Research Council (SERC) of Department of Science and Technology (DST) announced the Indo-US Research Fellowships.This is an effort to augment scientific excellence in ernerging areas of science and technology, The objective of the fellowship is to enable young researchers from India to carry out research in frontier areas of science and technology at a premier institution in USA. The fellowship will enable early and mid career Indian researchers to acquaint themselves with new scientific research methods and at the same time build strong oilaborative linkages between the scientific communities of US and India.
This is a normal rhythm, and is not of diagnostic significance unless the rate, which ranges from 60 to 100 beats per minute, is not appropriate for the clinical setting.
This rhythm differs from normal sinus rhythm only in that the rate is above 100 beats per minute. The differential diagnosis is extensive. Common causes are anxiety; physiological stress such as hemorrhage, dehydration, sepsis, and fever; and hyperthyroidism. Correction of the underlying cause, if necessary, is recommended.
