[@bryannkidz4790]

this is by far the best explanation in whole youtube on CF...

[@gamerrobotfans]

Great lecture sir. One correction, cystic fibrosis is a monogenic disorder. involving a single gene which codes for the protein CFTR. What you are talking about is deletion of three nucleotides which codes for phenylalanine, the most common of all mutations- F508 del. there are in fact more than 1500 mutations causing cystic fibrosis.

[@mahsamousazadeh4512]

Medicine and reading textbooks are truly difficult unless someone like you start to teach it with all of his efforts

[@ghazanfarhussain8793]

Best lecture ! Cleared out my confusions regarding different mechanisms in sweat gland and digestive secretions! Great explanation Sir!

[@heathermace8765]

Thank you your video. I am a Respiratory Therapist who been out of the field for a few years and now have my first grandbaby diagnosed with CF from the baby screening that was done after she was born.
Your video is a great refresher and I am wanting to learn as much as I can. When it is your own it is a little different with your own. Your brain does not remember everything that I learned in college or on the job.

[@karlanavarro1830]

They thought my niece was going to be sick from this because both parents are CF carriers but my niece is healthy, she is turning 10 soon and hardly ever gets sick from anything.🙏🏼

[@DrBeenMedicalLectures]

Good for her. Praying that she always stays healthy, prosperous, and happy.

[@anugraharajan5250]

Please make more videos Sir
We need more teachers like you!!

[@asmakhatun3634]

It's you only sir, who is able to make me understand the pathophysiology of CF in my medical carrier of 17 years.
Thank you sir.

[@journey7887]

Thank u. Its my first lecture.It is awesome..first time i got the real story behind cystic fibrosis ✌

[@DrBeenMedicalLectures]

You are most welcome. Glad the lecture is valuable.

[@abdulhamidabdalla7777]

Good explanation, just wanted to clarify at @1:30 that 3 genes are not deleted bur rather within the cftr gene a single nucleotide codon that sequences the amino acid phenylalanine is deleted thus leading to some conformational changes in the translated protein

[@ankitapatel4893]

Thanks a lot... sir...your explanation skill is too much good...sir..🙏

[@DrBeenMedicalLectures]

You are very welcome!

[@patelparth1800]

No word for your lacture sir.. thanks and make more video for us ...

[@arujghaffar3280]

Such a detailed explanation with easy understanding... Best lecture I have heard ever about CF. Thank you Sir.

[@matthewswartz1353]

Don't you mean three bases are deleted instead of 3 genes? There is only a single CFTR gene. The phenylalanine is the 508th amino acid that is deleted, but not 3 whole genes...

[@imranullah6476]

extremely thankful for a very important lecture.
First time, I got the answer of my question of salty sweat basis.
Hats Off to the lecturer

[@abdulpandit]

[@rupalipatil9714]

No mention of ivacaftor agent which reverses abnormality in chloride channels used in G551D defect cystic fibrosis .
One of the best explanation of cystic fibrosis .

[@dr.gmbrohi7977]

At the end of lecture plz repeat all points again 🙏🙏tnx

[@ericac2355]

Great lecture. Question though, isn’t it most often that males are infertile due to congenital agenesis of the vas deferens in CF and not due to thick secretions?

[@shahabuddin6149]

Great explanation

[@anugraharajan5250]

Great explanation Sir...

[@VampireDiariesBiebs]

absolutely brilliant and logical. thank you dr!

[@AddisuYAlem]

It is great explanation on the pathophysiology aspect. ON the treatments part, there is also a new approach of CFTR correctors/modulators that you didn't mention. These drugs improve/modulate the CFTR chloride channel performances. Few products approved by FDA and being used by health care community are Symdeko (FDA approved February 2018), Ivacaftor ...

[@AfifBashar]

Awesome sir. Love your lecture

[@DrBeenMedicalLectures]

Thank you dear 😍

[@akshatsahai3551]

Simple, short and brilliant
Thank you sir :)

[@akshatsahai3551]

However could you please detail about the channels which are working differently in sweat glands and respiratory system.? Detail as in more precisely the mechanism and effects.
Would be grateful !

[@anugraharajan5250]

One doubt Sir, chloride ions in respiratory tract where do they ultimately go? Reabsorped or secreted?

[@JiyaRajput468]

Great...👍

[@James-yc6zw]

Sir I have a question, if CFTR Cl- is not present at all. How come Chlorid Ions get inside the cell?

[@rakshithakgowda5662]

Sir there is a problem with cftr channel (chlorine channel) so chlorine won't be absorbed but why sodium channel won't work to absorb again

[@maaz1795]

Sir....i had a doubt...the expired air is considered to be more warm than the air inspired.The reason stated is with the physiological heat of our RT and water vapours. Can u explain from where did water vapours originate???

[@DrBeenMedicalLectures]

Water vapors come from the moist airways. Water is part of the airway secretions.

[@meseretasfaw3823]

They are water molecules originated from the surface of the respiratory epithelium, when a dry air is passing across the respiratory passage

[@drhamdaankhan3691]

cool one👍

[@jenniferevangeline653]

my child is "salty" when i kiss him hahahha. great lecture btw! thankyou!

[@jjhlk6737]
