Paragonimiasis | Lung fluke and its Life Cycle
Paragonimus westermani (Japanese lung fluke or oriental lung fluke) is the most common species of lung fluke that infects humans, causing paragonimiasis Human infections are most common in eastern Asia and in South America.
More than 30 species of trematodes (flukes) of the genus Paragonimus have been reported to infect animals and humans. Among the more than 10 species reported to infect humans, the most common is Paragonimus westermani, the oriental lung fluke.
Eggs: Paragonimus westermani eggs range from 80 to 120 μm long by 45 to 70 μm wide. They are yellow-brown, ovoid or elongate, with a thick shell, and often asymmetrical with one end slightly flattened. At the large end, the operculum is clearly visible. The opposite (abopercular) end is thickened. The eggs are unembryonated when passed in sputum or feces.[4]
Cercaria (not shown): Cercariae are often indistinguishable between species. There is a large posterior sucker, and the exterior is spined.
Metacercaria: Metacercariae are usually encysted in tissue. The exterior is spined and has two suckers
Adults: Adult flukes are typically reddish-brown and ovoid, measuring 7 to 16 mm by 4 to 8 mm, similar in size and appearance to a coffee bean. They are hermaphroditic, with a lobed ovary located anterior to two branching testes. Like all members of the Trematoda, they possess oral and ventral suckers.

Mismatch Excision Repair in Eukaryotes
Переглядів 384День тому
DNA mismatch repair (MMR) is a system for recognizing and repairing erroneous insertion, deletion, and mis-incorporation of bases that can arise during DNA replication and recombination, as well as repairing some forms of DNA damage. Mismatch repair is strand-specific. During DNA synthesis the newly synthesised (daughter) strand will commonly include errors. In order to begin repair, the mismat...
Fatty Acid Synthesis in Plastids
Переглядів 29714 днів тому
The plastidial fatty acid synthesis requires acetyl-CoA, ATP and NAD(P)H as substrates, and multiple routes exist to provide these substrates, although the relative importance of these routes depends on the sources of plastids. Fatty acid synthesis in plastids occurs mainly in plants. Plastids are specialized organelles found in plants and algae that play important roles in many metabolic proce...

An ear is the organ that enables hearing and (in mammals) body balance using the vestibular system. In mammals, the ear is usually described as having three parts: the outer ear, the middle ear and the inner ear. The outer ear consists of the pinna and the ear canal. Since the outer ear is the only visible portion of the ear in most animals, the word "ear" often refers to the external part alon...

Hemolytic anemia or haemolytic anaemia is a form of anemia due to hemolysis, the abnormal breakdown of red blood cells (RBCs), either in the blood vessels (intravascular hemolysis) or elsewhere in the human body (extravascular).

Anemia is a blood disorder in which the blood has a reduced ability to carry oxygen due to a lower than normal number of red blood cells, a reduction in the amount of hemoglobin or hemoglobin abnormalities. The name is derived from Ancient Greek: ἀναιμία anaimia, meaning 'lack of blood', from ἀν- an-, 'not' and αἷμα haima, 'blood'.When anemia comes on slowly, the symptoms are often vague, such ...

Amazingly clean explained, thank you so much! Definitely will watch more of your videos to get a better understanding of neurobiological topics! Greetings from a chemistry student
Hello I really enjoyed your video… but where is STAT3? In other places it seems that stat1 and stat2 are labelled stat3, as well as the two stat molecules stuck together. Can you explain where Stat3 is please? Really appreciate your help. X
First of all thank you so much for appreciation and feedback.... Secondly i can see the STAT 2 rarely forms Homodimer that is why u can't see STAT2-STAT2 complex in all papers or literature.... Phosphorylated STAT2 was found to be capable of forming homodimers in response to IFNα. These STAT2 homodimers were shown to interact with IRF9 to form an ISGF3-like complex....
we mostly get to see stat2-stat1... stat3 and other heterodimers ....
mostly we get to se heterodimers of stat2-stat1.. stat3..
@@hussainbiology so are you saying you just add up the stat heterodimers to get to stat3? Eg a stat1+stat2 = stat3? Stat3 is an important pathway for many cancers.
@@SheDaresLIVE no no..... i mean we don't have Stat2-stat2 homodimers very often..... rather we have stat3-stat1.... stat2-stat1
Definitely I will subscribe and support the channel you saved me from long hours of lectures. Thanks a lot for saving my exams ❤
I saw the pheran. Omg you are a Kashur boooi. You are doing great, keep it up
shukriya boi...... salamat roziu
Thanks a lot!
I like ur videos but ur pronounciation for some words 😑 pollowed ❌followed ✅
apologies
Apki english omg
❤
Sir please do video about anterior posterior polarity
Rabies is just one evolutionary step away from being able to create zombies. Attacking the emotion and memory centers harder might create feral behavior's in those infected.
mangifique wllh
thnk y brooo
you saved me
merciiiii
extraaa
woooow perfect
What have you done in biology like what degree?
@@hussainbiologylike masters in I mean to say that whats you specialization in biology
zoology brother
Isnt this what an at home stim machine can promote? (the kind that you use for a sore back/knots etc?
The way you elaborate such topics is greatly appreciated 👍
Shabir, Thank you for this interesting microbiology 🧫🔬 video. 🦂➡ 🏊➡🐌. 👏👏👏👏👏
Thank you for this video. I am trying to learn how the histamine system works. How it can be suppressed with medications that don't cause drowsiness (like loratidine). And how it can be exploited for use in alternative medications like armodafinil which might have a histamanergic mechanism of action.
Thankyou ❤
THANK YOU
Teri ma ki
tnx a lot
this was very helpful, thank you🙏🏼
Mahakal bless you my son keep doing jai shree ram
it inculdes types also right?
Sir pls need this chart in pdf format. This was immensely of great help
Amazing video, really helped me in understanding how eNos become NO
Thanks ❤
most welcome.... Keep sharing
What happens if it's the opposite strand that has the incorrect nucleotide?
Parental strand will never become one if not repaired at first place.. All daughter strands will become parental once repaired after Replication
@@hussainbiology I think I understand. During DNA replication the parental strand is methylated. It is then copied. It is assumed that the parental strand is correct. With the mismatch repair proteins any mistake in the daughter strand is repaired. 🧬 ✅ Shabir, Another solid video! Thank you so so much. I don't know if you have the energy to do a deep dive into just one of those proteins and show the active site and how any mineral co-factors are added during their construction. The molecular 🔬stuff is very interesting. 👏👏👏👏👏
@@michaeleisenberg7867 surely i will do
I like it the repair mismatch animation please upload the series of DNA repair I hope you give us great knowledge....thanks shabir hussain..
I appreciate you mentioning the helper proteins like GEFs and GAPs. This gives both students of lower studies and higher studies the change to learn what they need to learn. However, I need to see this pathway a bit more detailed and complex than this, so this video is not for me (Bioscience engineering cell & gene). I would love for you to step up the detail game a bit.
first of all thanks... I really appreciate ur feedback and you are right... i need to get into details so that guys like can get any kind of help... I can understand for ur studies this is just an introduction but i assure you i will definitely get into details
I like your diagram
Commendable
thanks Insha for appreciation....

Sir I have a doubt
Biosynthesis heading nhi di video ki 😢

done now....
Wow
Is calmodulin also present in endothelial cells?
Keep it up ❤
Holy poop this video cleared up so much I had a eureka moment thank you so much
