Very good lecture/lesson, even I who have no qualifications in biology, biochemistry, physics, chemistry etc can make sense of it. So glad to subscribe. Thank you!
It's glad to hear that you are from Bangladesh sir. I am also learning in a govt medical in BD. I didn't understand the topic before your discussion. Thanks a lot sir
Hello doctor - thank you for the video. I am using a hydroxyl generator/ also known as photocatalytic generator to clean my air. I tried all kinds of filters before I started using this technology and none helped. This machine helps me to live indoors without getting sick. I have been using it for 2 years and I feel fine -- great even. Some others express concern about the HO radical it produces causing harm. Do you know anything about this artificial generation of HO and how that does or does not effect the body?
Wooow thank u sirr, it was wonderful and after searching many vedios on youtube finally I could understand that whats free radicals. Waiting for ur more vedios.
Thank you for your feedback. Take care and stay blessed. Here is a link of my new immunology video on transplantation and graft rejection. th-cam.com/video/o2vm2Sh1W84/w-d-xo.html
Hi, what do you think about lipids peroxidation of polyunsaturated fats inside the human body? How have read many research saying it's highly toxic because of free radicals caused by oxidation of unstable polyunsaturated fats (omega 3, omega 6s). Please share your perspective.
I dont have a science background. To me its a bad explanation. I can only understand in general. You introduce chemical agents, ros and radical without differentiating them.
hiii... your lectures are really useful.. i noticed your recent lectures are on ppt unlike on blackboard.. but i found d ones on blackboard more useful.. so it will be very kind of u if you make your videos on d blackboard and also we can see a real teddy :) Thanks a lottt..
SURAJ KARANJE Thank you for liking my videos. I miss my white board too. I am currently placed out side the capital city for studying post graduation course on MD Pathology and my current city has slower internet service compared to Dhaka. So can't upload white board videos which were often larger than 2GB each. But internet service is gradually improving and may become same as the capital in a few months from now. I am also thinking of uploading whiteboard videos in segments and later join them using youtube video editor before publishing them from next month. Best wishes from Bangladesh. Real teddy will be back soon too :)
Thank you for your question. Ischemia-reperfusion injury can occur in several mechanisms. One of the mechanisms is caused by free radicals (Oxidative Stress). When an area of ischemia is reperfused there may be increased generation of free radicals in the area. Why? Since the area was ischemic and suffered from cell injury previously, the mitochondria of the affected cells are already damaged. So they cause incomplete reduction of oxygen (which came after restoration of blood supply) and produce excess free radicals. As the area previously suffered from ischemia, antioxidant defense mechanism is also compromised. Some free radicals are also generated by action of oxidases in leukocytes & endothelial cells in the ishcemic area. Ultimately the excess free radicals cause oxidative stress and this results in death of cells after restoration of blood supply. Take care and stay blessed. :)
Thank you for your feedback. New lecture on chronic lymphocytic leukaemia is now available in the channel. Link: th-cam.com/video/SyptroxJaSk/w-d-xo.html Take care and stay blessed.
Excellent. IAM not a med student, however I understand biology and chemistry very well from high school. Currently I presume nutritional supplements that counteracts cellular injury from these free radicals. I have been very successfully at reversing these injuries in patient's extremely Injured by radiations and chemethewrapies.

Is there anything wrong with that?Robbins is the standard textbook of pathology worldwide,if you have your own textbook publish so that we can also learn.
Your explanation of the material was very clear and excellent and I benefited a lot from it. thank you so much. Greetings to you from Iraq.
Thank you for your feedback. Take care and stay blessed.
Thank you sir ,please continue to make such videos , it’s so easy to understand when you teach .

thank you sir..
is cu29 a free radical?
because 4s1 comes before 3d10 so the 3e is completed while 4s1 electron is unpaired
Some metals are also responsible for generating ROS (Fe, CU) Can 'Ag' (used in woundcare also generating ros?
Very useful your teaching sir.thank you sir
