Novel nanospectroscopy measures biomolecular changes induced by drugs in human cells Kumar Jeetendra | July 20, 2020 Synchrotron InfraRed Nanospectroscopy has been used for the first time to measure biomolecular changes caused by a drug (amiodarone) in human cells (macrophages) and localized at 100 nanometre scale, i.e. two orders of magnitude smaller than the IR wavelength used as probe. This was achieved at the Multimode InfraRed Imaging and Micro-Spectroscopy (MIRIAM) beamline (B22) …
SUTD researchers utilize 3D printing to make heart cells from undifferentiated organisms Kumar Jeetendra | August 12, 2020 All people start out from one cell that then divides to eventually form the embryo. Based on the signals sent with their own adjacent cells, these divided cells are then developed or differentiated into particular organs or tissues. In regenerative medicine, controlling this differentiation from the lab is crucial as stem cells could be distinguished …
Designers develop plant-based splash that could be utilized in N95 mask filters Kumar Jeetendra | October 7, 2020 Engineers have invented a way to spray extremely thin wires made of a plant-based material that might be used in N95 mask filters, devices that harvest energy for electricity, and potentially the production of human organs. The procedure involves spraying methylcellulose, a renewable plastic material derived from plant cellulose, on 3D-printed and other objects ranging …
Patients’ own stem cells can be utilized to develop new bones, study shows Kumar Jeetendra | November 23, 2020 A new, groundbreaking study from the University of Bergen (UiB) shows that a patients’ own stem cells can be used to grow new bone. This can potentially help millions of people who are partially edentulous and have inadequate bone for placement of dental implants. The Maxibone Project, coordinated by Pierre Layrolle, Inserm, University of Nantes, …
Resonance-guided vaporization may give better approaches for treating tumors Kumar Jeetendra | February 4, 2021 Sending tiny droplets to a tumor and having them vaporized using focused ultrasound: it might be a new way of tracing a tumor or send drugs locally. Researchers of the University of Twente in The Netherlands now demonstrate a new phenomenon triggering droplet vaporization: it occurs at the exact acoustic resonance frequency and causes fast …
Hereditary components of human gut microbiota are key to wellbeing Kumar Jeetendra | February 6, 2021 Neanderthals’ gut microbiota already contained some beneficial micro-organisms that are also found within our own intestine. An international research group headed by the University of Bologna achieved this result by extracting and analyzing ancient DNA from 50,000-year-old fecal sediments sampled at the archaeological site of El Salt, near Alicante (Spain). Published in Communication Biology, their …
Central amygdala micro circuits assume dynamic part in regulation of dread responses Kumar Jeetendra | July 17, 2021 Because they can be used to treat anxiety disorders, the brain mechanisms that suppress fear reactions have been a focus of much attention. Although we have a good understanding of the brain regions that are activated when fear is experienced, it remains to be largely unknown how fear reactions can be suppressed. Researchers from the …
