New York: A team of researchers led by an Indian-American scientist has developed a portable biosensor that can display the progress of Alzheimer’s disease in a patient.
A test on the cheap and simple biosensor can measure the level of a protein called beta-amyloid, increased level of which leads to the degeneration of brain cells and causes Alzheimer’s, in the blood at tiny concentrations in just half an hour.
“We want to develop a point of care system, where a small drop of blood plasma can reveal their beta-amyloid level immediately so that a doctor can tailor a patient’s therapy immediately,” said lead author Ajeet Kaushik from the University of Florida in the US.
The protein, which is found in lower levels in the blood, makes it a useful biomarker to diagnose and monitor the disease progression.
A quick test on the biosensor can reveal a clinician to collect accurate information on the progression of the disease and see what is happening to a patient over time.
It will also show if and when the disease reaches an untreatable level, the authors reported in the study published in the journal Biosensors and Bioelectronics.
The researchers pointed out that the affordable test can be useful in both developed countries and rural settings. Also with the right data, doctors can respond quickly to changes in a patient’s brain by reducing or increasing their dose of drugs. (IANS)
Indian-American scientist Rajiv V. Joshi has won the New York Intellectual Property Law Associations Inventor of the Year Award for his pioneering work in advancing the electronic industry and improving Artificial Intelligence (AI) capabilities, it was reported.
An Indian Institute of Technology (IIT) Bombay alumnus, Joshi was presented the 2020 award “in recognition of the contribution that the invention has and/or will make towards society as a whole” earlier this month during a virtual awards ceremony, said the American Bazaar report on Friday.
A research staff member at IBM’s Thomas J. Watson Research Center, Joshi holds 235 US patents.
His work focuses on the development of integrated circuits and memory chips.
He is a fellow of the Institute of Electrical and Electronics Engineers (IEEE) and received the Industrial Pioneer Award from the IEEE Circuits and Systems Society in 2013 and the IEEE Daniel E. Noble Award in 2018.
Joshi holds a B.Tech. degree in mechanical engineering from IIT Bombay. He came to the US in 1977 to pursue a master’s degree at MIT and a doctoral degree at Columbia University.
According to Joshi’s biography, his novel interconnects processes and structures for aluminium, tungsten, and copper technologies are widely used in IBM for various technologies.
Joshi has extensively worked on novel memory designs and commercialized these techniques. He received three Outstanding Technical Achievements (OTAs) and three highest Corporate Patent Portfolio Awards for licensing contributions.
A Distinguished Visiting Professor with IIT Roorkee, he was inducted into the New Jersey Inventor Hall of Fame in August 2014 along with the pioneer Nicola Tesla. (IANS)
A prominent Indian-American businessman has urged US President Donald Trump administration to reopen the country’s economy with “common sense precautions”, highlighting the struggles America’s hoteliers were facing during the COVID-19 lockdown, the media reported.
Speaking at a roundtable of hospitality and tourism industry, hosted by Vice President Mike Pence in Orlando on Wednesday, Danny Gaekwad, Chairman of OSEM Hospitality Management, said such a move will “help our industry and our state get our economy moving again”, the American Bazaar reported on Thursday. Gaekwad was speaking as a representative of the Asian American Hotel Owners Association (AAHOA).
Besides Pence, the event was attended by Labor Secretary Eugene Scalia, Florida Governor Ron DeSantis and several prominent business leaders from the state. Gaekwad and other industry leaders proposed a number of steps and a phased reopening of the economy. “This pandemic hit the hotel industry particularly hard, and owners and employees alike continue to struggle,” said Gaekwad, also a prominent Republican donor, told Pence.
“Reopening our businesses with common sense precautions that prioritize the health and wellbeing of employees and guests will help our industry and our state get our economy moving again.” Gaekwad, a resident of Ocala, in central Florida, drew Pence’s attention on the liquidity crisis members of AAHOA, who own nearly one in every two hotels in the country, were facing.
“If there is no guest, there is no dollar. If there is no dollar, don’t even think about liquidity. Do we have liquidity? Absolutely not,” the American Bazaar quoted the businessman as saying.
“As an immigrant, my whole family works in a business because it does bother us. I represent here more than 20,000 (AAOHA) members. We all came with an American Dream. I thought I saw 9/11, I thought I saw the greatest recession. I have never seen this and I was never prepared for this.” (IANS)
From historical times, human beings have been surviving, inspite of several types of diseases confronting them. In such conditions, medical science to safeguard human beings from diseases have been developed due to the compelling need for survival of humanity.
Traditional medicines :
In ancient India, there were reports of several medicinal practices and development of several types of drugs for treatment of different types of illness , which were mostly based on natural products and not developed by synthetic process. Traditionally, such Indian medical practices have been termed as Ayurveda, Siddha etc.
In other countries too, such traditional medical practices have prevailed under various names such as homeopathy , Unani etc.
In short, the world have been living with diseases from time immemorial and has been responding to the diseases by developing appropriate medical procedures from time to time.
Development of new diseases :
With the changing life style of people, development of synthetic production processes for cosmetics , chemicals, fertilisers, pesticides, etc. and environmental hazards created by industrial operations and transportation, promotion of new food items etc. newer diseases have also been steadily arising.
Efforts of medical researchers :
The medical researchers have not lagged behind and have been developing new drugs and vaccines to treat the new and emerging diseases.
Some of the synthetic drugs developed for treatment of diseases were also reported to have side effects , which cause more diseases and sickness .
Regulatory authorities have been from, time to time, imposing ban on some of these drugs, due to unacceptable side effects, though the damage due to such banned drugs would have already happened.
COVID 19 latest addition :
COVID 19 is the latest addition to rest of diseases in the world.
Huge international efforts have now been taken up to identify the root cause of COVID 19 and develop appropriate drug / vaccine to treat the disease.
Given the past success ratings of medical researchers in handling other diseases, one can be hopeful that before long, appropriate drug / vaccine would also be developed to treat COVID 19 patients.
Limitations of medical research :
While the medical research have developed phenomenally , the medical research have not been able to prevent the occurrence of the disease , except in a few cases. Of course, in the case of polio attack, vaccines given to the children at the right time have largely eliminated the polio disease in the world.
However, this cannot be said about several of diseases such as cancer, influenza etc. which continue to occur at very high level and are being treated.
Similar situation may prevail in future in the case of COVID 19 too, with medical researchers unable to prevent it but only treat it.
Alarm due to COVID 19 :
In the case of COVID 19, the world has reacted with huge alarm , as if the COVID 19 would wipe out the entire human race.
Several world governments have declared lockdown and brought the global economy nearly to a half , like of which it has never happened before in human history.

While the panicked world is still viewing COVID 19 with great fear and medical researchers are striving hard to develop treatment procedures, certainly the day will come when the world would reconcile itself to the prevalence of COVID 19 , just as it has reconciled itself to the prevalence of diseases like cancer, flu etc. and would also be prepared to treat the disease with appropriate procedures.
Is there over reaction to COVID 19 crisis ?:
Possibly, after six months or so from now, when COVID 19 crisis would settle down, the world community would look back at the COVID 19 crisis and would wonder whether the world has over reacted to the COVID 19.
The world would calculate the number of people infected by COVID 19, recovered and died. Then, after reading this calculations, the world would inevitably come to the conclusion that it has not been as bad at all as it was feared at one time, as the world community would remain intact after COVID-19 crisis.
It is estimated that around 0.15 million people die in the world every day due to various reasons such as old age, cancer, heart attack, kidney failure, virus attack etc. It translates to around 54 million people die in the world every year.
Till date, around 0.25 million people have died due to COVID-19 over the last four or five months.
Probably, when the COVID-19 crisis would end one day , the number of deaths due to COVID-19 could be just less than 1 million, considering worst scenario.
In future, after the end of present COVID-19 crisis such scale of deaths due to COVID-19 are unlikely, in view of the development of appropriate drugs to treat it.
This projected death figure of just less than one million due to the on going COVID19 crisis, do not add much to the worldwide death of 54 million every year in normal times.
Lives vis a vis livelihood debate :
Of course, death is natural and inevitable. It occurs for people in various age groups and due to natural / disease factors and unnatural factors such as accidents, murders, war etc. Every individual has to reconcile oneself to the inevitable event of death that would happen one day for everybody.
In such circumstances, is it appropriate that the world economy should have been brought down to the level of stagnant or decelerating growth over several months in the year 2020, fearing COVID-19.
Due to such near global lockdown, billions of poor people have been put to hardships , large number of people have lost the jobs, many production centres are facing closure and appears that it would take some time for the world to recover from this losses due to lockdown , fearing COVID 19.
