Cancer-Fighting Nanorobots Can Shrink Tumours

2 days ago
In a major advancement in nanomedicine, an international team of scientists has successfully programmed nanorobots for the first time in mammals, that potentially shrinks tumours by cutting off their blood supply. Each nanorobot is made from a flat, rectangular DNA origami sheet that is 90 nanometres by 60 nanometres in size. Once bound to the tumour blood vessel surface, the nanorobot was programmed to deliver its unsuspecting drug cargo in the very heart of the tumour, exposing an enzyme called thrombin that is key to blood clotting. The nanorobots worked fast, congregating in large numbers to quickly surround the tumou...

New Way To Predict Chemo Outcomes

4 days ago
n SSB BUREAU Scientists have developed a new optical imaging system that uses red- and near-infrared light to predict response to chemotherapy by as early as two weeks. “There is currently no method that can predict treatment outcome of chemotherapy early on in treatment, so this is a major advance,” said Andreas Hielscher, professor at Columbia University.  The novel dynamic “optical tomographic breast imaging system” generates three-dimensional (3-D) images of both breasts simultaneously.  The images also enable the researchers to look at blood flow in the breasts, see how the vasculature changes, and how the blood inte...

First Urine Producing Kidney Tissue Developed

4 days ago
In a first for medical science, scientists have successfully produced human kidney tissue within a living organism that is able to produce urine, a significant milestone in the development of treatment for kidney disease. Using stem cells, scientists from the University of Manchester, created mini-kidneys that were implanted into mice. Tests revealed they were able to filter and excrete waste. In the study, published in the journal Stem Cell Reports, kidney glomeruli – a constituent microscopic parts of the organ – were generated from human embryonic stem cells grown in plastic laboratory culture dishes. These were combined with a gel like substance, which ...

LAB-GROWN LIVER MODEL HELP ADVANCE TREATMENT

a week ago
New York: The liver organoids, made with human cells, are less than one-third inch in diameter. These will also help advance scientists understanding about bile duct formation. This model better mimics foetal development and function of the human liver," said lead researcher Shay Soker, Professor at Wake Forest University in North Carolina, US. "We expect these organoids to advance our understanding of how liver diseases -- especially congenital diseases -- start and pr...

SCIENTISTS USE SILK TO DEVELOP ARTIFICIAL VERTEBRAL DISC

2 weeks ago
Degenerative disc disease is a major cause of low back pain affecting mobility of people. A group of Indian scientists have developed a silk-based bio-artificial disc that may find use in disc replacement therapy in future. At present, therapeutic treatment for degenerative disc disease can only provide symptomatic relief of pain without restoring the functions of discs, while disc replacement surgery is very costly. The use of a silk bio-polymer to fabricate a biocompatible disc can reduce the cost of artificial discs in future, claim researchers from the Department of Biomaterial and Tissue Engineering at Indian Institu...

BIRTH DOSE OF HEPATITIS B VACCINE MAY NOT BE NECESSARY: STUDY

3 weeks ago
A new study by a group of Indian Pediatricians shows that many newborns are protected from Hepatitis B infection by antibodies they receive from the mother and therefore hepatitis B vaccination at birth may not be necessary. Hepatitis B, a viral infection which causes liver cirrhosis or liver cancer, is a cause of one lakh deaths per year in India. This disease spreads by contact with infected blood or body fluids and can pass from mother to baby, child to child, through blood transfusions and unprotected sexual contact. Over 40 million Indians are chronically infected with Hepatitis B. Many people can live without sympto...

PRESIDENT KOVIND RECOMMENDS VIPASSANA

4 weeks ago
Vipassana meditation purifies the mind and its practice leads to increased concentration, resulting in beneficial effects on body and mind, and in turn to the entire society, President Ram Nath Kovind said here. He said Vipassana comprises three simple precepts -- morality, concentration and self-realisation -- through awareness and insight, and is a non-sectarian meditation technique that applies equally to all human beings irrespective of caste, religion, language, gender or age. The Vipassana meditation technique, taught by Lord Buddha, has attracted people in large numbers not only from Maharashtra but all over...

WEIGHT-LOSS SURGERY MAY CUT HEART DISEASE RISK

5 weeks ago
Bariatric surgery may minimise the risk of heart diseases in adolescents who went through the procedure, claimed new research. The findings showed that bariatric or weight-loss surgery performed during adolescence may provide unique benefits later in life by minimising the development and progression of impaired glucose metabolism, atherosclerosis heart failure and stroke. “This is the first large-scale analysis of predictors of change in cardiovascular disease risk factors among adolescents following bariatric surgery,” said Marc P Michalsky, Professor at the Ohio State University College in the US.

EATING PROBIOTICS CAN HELP PREVENT DEPRESSION

6 weeks ago
Besides keeping your gut healthy, consuming a diet rich in probiotics -- also called as “good” or “helpful” bacteria -- may help protect against depression, finds a mice study. Probiotics are live bacteria and yeasts that are good for health, especially the digestive system. The findings showed that rats which lived solely on the fatty diet were found to develop behaviour similar to depression, while the rats receiving the probiotics-enriched drinking water remained neutral in their behaviour. Further, the rats that did not receive probiotics had an increased number of white blood cells in their brain tissue, which can be a sign of chronic i...

Retinopathy detecting AI Developed Kavya Kopparapu, a 16-year-old has successfully programmed an artificial intelligence program that  makes an early diagnosis of diabetic retinopathy. She was motivated to do the same after her grandfather started losing his vision due to diabetic retinopathy. Her device comes with a 3D-printed lens that can cut the tedious two-hour long diagnostic procedure to produce a retinal image. Perhaps more importantly, it reduces the cost from thousands of dollars to a quick photo snapped with a phone The device uses a form of artificial intelligence to recognize signs of diabetic retinopathy in the photographs clicked &n...

NUTS, OILY FISH CUTS KIDS’ RISK OF ASTHMA, RHINITIS

10 weeks ago
Including nuts, oily fish like salmon, flax seeds, and soybean oil – rich in essential polyunsaturated fatty acids – in your children’s diet may prevent their risk of developing allergic diseases, especially asthma and rhinitis by teenage, a study has suggested. Both asthma and rhinitis affects the kids since their childhood, either due to hereditary or environmental factors.  The results show that the presence of an increased amount of polyunsaturated fatty acids such as Omega-3 and an omega-6 fatty acid called arachidonic acid in the blood is associated with a reduced risk of allergic disea...

HOUSEFLIES COULD CARRY HARMFUL BACTERIA

12 weeks ago
Flies may be more than pesky picnic crashers as researchers have found that they could also carry hundreds of bacteria harmful to humans and play a role in spreading diseases. Because flies often live close to humans, scientists have long suspected they played a role in carrying and spreading diseases, but this study, published in the journal Scientific Reports, adds further proof of that threat. “We believe that this may show a mechanism for pathogen transmission that has been overlooked by public health officials, and flies may contribute to the rapid transmission of pathogens in outbreak situations,”...
