Sperm donors vs human milk donors - another injustice against women

-
Image
 Indian culture is ant-women though it is a taboo to talk about this fact. Laws also do not support truly. There is something else written and something else said and done.  Women are usually put on more manual jobs and paid less. They are rarely given leadership jobs though they could have been better leaders of the hurdles in their lives were abolished.  Now coming to sperm donation vs human milk donation. If you see both, and think on those, you will realise that human milk donation is much more valuable and useful. Yet, human milk donors are either not paid or are paid less. But sperm donors are always paid and paid more. Why this difference???? Read: How to eat idlis? Law fails to help these mothers who I would say are exploited in the name of humanity. When sperm donation and surrogacy are compensated, why not human milk donation be compensated at par??? A food for thought!!!

A novel drug against coronavirus is under study at Washington University School of Medicine in the USA

-

 Scientists at Washington University School of Medicine in the US have developed a new antiviral compound that blocks covid virus from entering human cells. They have named this compound MM3122. They state that if given early in the disease course they could reduce severity of the dreaded illness. 

Mechanism of action of MM3122

The compound acts on the key human protein called transmembrane serine protease 2 (TMPRSS2). Covid-19, other coronaviruses and influenza virus uses this protein to enter and infect human cells. James W Janetka, senior author of this study states:

“Great vaccines are now available for SARS-CoV-2, but we still need effective antiviral medications to help curb the severity of this pandemic,” 

“The compound we are developing prevents the virus from entering cells,”


They want to develop an oral form of this inhibitor that could help in covid infection and minimize its severity. The authors add that the compound also blocks another related protein called matriptase. Matriptase and TMPRSS2 are found on surface of lung cells as well as other cells. Their inhibition prevents spike protein activation and membrane fusion. James explained:

“The SARS-CoV-2 virus hijacks our own lung cells’ machinery to activate its spike protein, which enables it to bind to and invade lung cells,”

“In blocking TMPRSS2, the drug prevents the virus from entering other cells within the body or from invading the lung cells in the first place if, in theory, it could be taken as a preventive,”

Stage of the study

The study is still preclinical. The new compound is being tested on mice. Once it undergoes the efficacy and safety studies, it could be used as a broad-spectrum antiviral drug. Remdesivir is already approved for use in covid. The new compound, the authors state is better than remdesivir too. The compound is also proven to be effective against the original Severe Acute Respiratory Syndrome coronavirus (SARS-CoV) and Middle Eastern Respiratory Syndrome coronavirus (MERS-CoV). The study co-author Sean Whelan adds:

“The majority of inhibitors of viral infection work by blocking steps of replication once the virus is inside the cell,”

“Dr Janetka has identified and refined a molecule that stops the virus from entering the cell in the first place. As the target of MM3122 is a host protein, this may also pose a larger barrier to the emergence of viruses that are resistant to the inhibitor,” 

The compound offers a ray of hope against the 21st century bad viruses that evade treatment until now.

Loneliness is a growing epidemic especially during this coronavirus pandemic in the USA!

-
Image
  The coronavirus pandemic has increased social segregation and this has proven to be bad particularly for the elderly population. They are unable to catch up with their children and grandchildren and are finding themselves extremely lonely. They are the worst affected by the pandemic in terms of physical as well as emotional health. THE OLD AGE AND LONELINESS Old age is a time of loneliness for many people. Usually, people have lost their partners at that ripe age and depend on their children and grandchildren for support and to beat the loneliness. Though their younger family members used to occasionally visit the parents, now with the coronavirus pandemic this has become difficult due to the risk of the children carrying the infection to their aged parents and grandparents. So the visits have come down drastically and the contact remains only on phone or via digital technology. This though good does not suffice and cannot substitute the physical visits and the warmth that th...

Small wounds on your dog-causes, symptoms and treatment explained!

-
Image
Most of the dogs that are kept as pets are extremely active and move in and out of the house. Only celebrity dogs or those whose owners are extremely wealthy lead a lavish life. The others due to their outdoor or sometimes even indoor activities might suffer some minor wounds. These should not be left unattended and need to be addressed immediately. These can be in the form of small cuts, scratches, or even bites. So how to take care of these small wounds on your dog pets?  Dogs and the causes of wounds Many times, your pet dogs might suffer some small wounds, cuts, and scratches. Dogs like children and play around with them. In the process, they might hurt themselves which is natural. This may be in the garden or lawns or while running around the trees or even while jumping.  Dogs and wounds [Source: Pinterest] The dog may also be playing around with another canine or cat in the house or outside and ends up getting a bite from them. At times, a dog walk through rough terrain ...

Color therapy-the ancient art of healing! Know the science behind it and its current status!

-

  Color as a form of therapy is not a new concept. In it, electromagnetic waves in the form of the visible spectrum (that we interpret as colors) are used to cure various body illnesses. It is an ancient mode of therapy that is being reinvented. There are attempts to elucidate its scientific basis and explanation. This would help to explore and discover newer dimensions of this old remedy. Color therapy (Chromotherapy) Newton talked about solid matter and moving objects while Einstein found out that mass and energy are dual expressions of the same universal substance. It is the vibration rate of its molecules that determines its form. When slow, it is physical matter and when the vibrations are intense it is energy. Thus, light is an energy and when it interacts with matter, color is formed. Each color has its own wavelength, frequency, and energy level. And human eye is adapted to see only this energy that has a wavelength between 380-780 nm. This is therefore, the visible spe...
