In posterior cross bite, which cusps would contact in mediotrusive movement?
No choices.

In respect to its effect upon movement of water btwn vascular and extravascular space, plasma colloid osmotic pressure acts in the same direction as
tissue pressure
venous pressure
capillary pressure
arteriolar pressure
tissue colloid osmotic pressure

From the facial view, where wud the CEJ be most apically positioned on the crown of primary mandibular first molar
mesial one third
middle one third
distal one third
Please solve the above questions. Explanations are most welcome. Thank you.

Please solve the above questions. Explanations are most welcome. Thank you.

for 1st question-the outer inclines of mand lingual cusps will contact the inner inclines of max lingual cusps.
plz feel free to correct if wrong.

 

[dentgod]

thanks pbkal. I thought the answer for the third wud be the distal third , just as the contact areas. You think wheelers wud be good to look for the answer?

[bombshell]

which is usually mistaken for subgingival calculus?
concrescent teeth or dens in dente?
is dense in dente ans for this??

Dens in dente is the most commonly causes of pulp inflamation when present in lateral incisors (max) (caries then pulp inflamation)
COncrescent teeth are joined together by the cementum - therefore mistaken for subgingival calculus. That's for sure!

carcinoma of larynx would effect?
deep cervical nodes,submandibular,thoracis lymph nodes?
is deep cervical nodes ans for this??

yes, it is the deep cervical nodes. That's for sure! 🙂

1.antivirals are(mode of action)
a against nucleic acid
b against rna
c against protien ------ pls confirm?

2.cns infection with insect vector is cauded by
ricketssiae or chlymydiae

3.sensory nucleus for v, vi, ix ,vii ,x nerve is
spinal nucleus of v
sensory nucleus of v
mesencephalic nucleus of v

4.vasculitis in children buergers/ kawasakis/ giant cell vasculitis .. is that kawasaki??

5. Which isn't a ischemic heart disease ?

hypertensive heart ds -- is this the ans??
angina pectoris
cardiac death

 

[bombshell]

1.antivirals are(mode of action)
a against nucleic acid
b against rna
c against protien ------ pls confirm?
antiviral drugs:
1. against nucleinic acids - as precursers ddC, ddI, 3TC or others
2. agaubst protease (protease inhibitors)
3. inh DNA like Acyclovir for example
4. in general substances against viral infections..

2.cns infection with insect vector is cauded by
ricketssiae or chlymydiae
Rickettsia species are carried as parasites by many ticks, fleas, and lice, that is it is carried by arthropods, leeches and protists.
Chlamydiae - touch, birds, inhalation

By this point - I will like to see more possible answers before choosing a define answer...

3.sensory nucleus for v, vi, ix ,vii ,x nerve is
spinal nucleus of v is only for pain and tempreture
sensory nucleus of v is for tactile, pressure sensation that is discriminitive touch
mesencephalic nucleus of v

4.vasculitis in children buergers/ kawasakis/ giant cell vasculitis .. is that kawasaki is the one in kids??

5. Which isn't a ischemic heart disease ?
hypertensive heart ds -- is this the ans??
angina pectoris
cardiac death

hope it helps

just for clarification, does HMG coa reductase produce cholesterol and HmG coa lyase produce ketone bodies? I think my book has it flipped.....

Thanks in advance.🙂

 

[bombshell]

just for clarification, does HMG coa reductase produce cholesterol and HmG coa lyase produce ketone bodies? I think my book has it flipped.....

Thanks in advance.🙂

HMG-CoA reductase is in fact HMG-CoA-lyase (lyases as class of enzymes are known to break chemical bonds)

HMG-CoA synthetase is the only enzyme which produces HMG-coA from the Acetoacetyl-coA (It is actually a acetyl-transferase)

Hope that makes it clear.

from my understanding, the above mentioned condition is the Cretinism or hypothyroidism in the children. By Kaplan, the cretinism wud have the increased TSH secretion for the early detection (pg no 191 endo path), so answer wud not be the choice c. I think choice B is right. Correct me for the mistakes.

U r right, but I don't think there is a correct answer among those answers.
if the "mutation" thing wasn't mentioned then the right answer would be (less iodine), but the mutation made it Cretinisim, and it had High TSH and low T3 and T4. the BMR would be decreased too.

 

[Gipsyking]

thank you mrswinidm. By which cycle does the maximum number of FAD is produced? No options available.

ETC, has three, while others have one each.
I am like 99% sure.

1.conflict between dentist n patient abt the treatment of extraction what principle shud be involved here-
--autonomy n non-malifeance
--autonomy n verasity

2.Which tooth might have a pulp horn less than the total number of cusps

3..- Only tooth with a cusp so uniquely prominent that posses a prominent triangular ridge that separates Mesial and distal?

.4.- the metabolite that helps messuring GFR is: inulin, creatinin? When do we have to answer inulin and when creatinine??

5. healing bone will show all except :
woven bone callus ,woven bone callus with composite bone, composite bone replaced by lamellar bone, it'll start laying down cartilagenous callus

6. A person canot hear vibrations of a fork, he can hear it if its kept on his mastoid antrum , this indicates wat damage ?

7.if u need to give an intramuscular nerve block in the oral region which muscle is preferred?? masseter, lat pty,med pt,tempo??

Pls reply to these as soon as possible, I'd really appreciate the help.

.Hi.
.Plz ans this qs
.

.
.each of the follow is necessary for viral antigen recognition by CD4 t helper except one?
1. viral replicaton in host cell
2. clevage of viral protein into small peptides
3. transport of viral peptides to cell surface by MHC clas2 molecule
4. binding of T cell TCR to MHC class2 bound viral particle
5. internalization of the virus by an antigen presenting cell.


Thanks
..

I thought APC were like macrophages and certain phagocytes that have MHC II molecules to present viral particles to T helper cells.

A virus is phagocytized by an APC --> viral proteins and cleaved and transported to cell surface of APC --> viral peptide presented on surface by MHC --> T cell receptors can now recognize MHC viral bound paticles.

I'm guessing the answer is 1 (viral replication). Pure guess though.
