I missed this... But let me add spices

The production of NADPH is to actually reduce the oxidized glutathione being produced in the RBC, catalyzed by Glutathione reductase. Product of the reaction actually removes H2O2 as radicals produced by the dissociation of H2O2 cannot be removed singly and it is also catalyzed by glutathione peroxidase(selenocysteine active site).
If that doesn't happen as in the deficiency of G6PDH, accumulation of H2O2 in the cell would have an oxidative effect on the cell membrane.

this is what one of my lecturer call Biochemical basis of Co cola Urine...

Please help me analyse this question and give correct answer urgently....please if you understand it kindly help out.

Identify which of the following are the characteristics of the vertebrate respiratory surface..1. Moist 2. Vascularised, 3. Semipermeable, 4. Freely permeable, 5. Dry
A. 1,2,3
B. 1,2,5
C. 2,3,5
D. 2,4,5
E. 1,3,5

The vertebrate respiratory surface must be moist to provide medium for the dissolution of respiratory gases. Highly vascularized so that oxygen can diffused in to the blood capillaries and Co2 diffused out. All these happens due to difference in osmolality between the two region; and hence a semipermeable membrane is needed to transport dissolved respiratory gases. I think you can now choose your answer.

jorrn:
Movement and position of head in man man are detected by the
A. Cochlea
B. Malleus
C. Utriculus
D. Semi circular Canal
E. Outer ear.

Equilibroception. It's the semi circular canal. It contains tube filled with fluid and the tubes have hair cell on their surface. Movement of the head causes the movement of the fluid and also displacement of the hair cell which sends signal to the brain for the processing of the type of head movement (nodding or sideway movement). Utricule and Saccule regulate linear movement.

Cogent and lucid explanation.....A is correct, from your analysis.

Utricule and Saccule regulate linear movement.

This question is controversial, to me the answer should be Utricule because it detects linear and horozontal movement of the head by the stimulation of the sensory hairs on the Otolithe.....Semi circular canal on the other hand detects rotational or spinning movement of the head. The nodding or sideway movement you spoke about is detected by the the utricule and saccule. My view, others can please contribute.

Movement of fluid in the semicircular canals signals the brain about the direction and speed of rotation of the head - for example, whether we are nodding our head up and down or looking from right to left. Each semicircular canal has a bulbed end, or enlarged portion, that contains hair cells. Rotation of the head causes a flow of fluid, which in turn causes displacement of the top portion of the hair cells that are embedded in the jelly-like cupula. Two other organs that are part of the vestibular system, the utricle and saccule, are called the otolithic organs and are responsible for detecting linear acceleration - movement in a straight line. The hair cells of the otolithic organs are blanketed with a jelly-like layer studded with tiny calcium stones called otoconia, organic calcium carbonate crystals crucial to the maintenance of equilibrium. [1] When the head is tilted or the body position is changed with respect to gravity the displacement of the stones causes the hair cells to bend. So from this, I guess the question is vague

But bear in mind dat the semi circular canal is used for balancing due to the fluid it contains, so we can say it does more of that than detecting movement... So my answer is utriculus

Hmm. Note this: Your question has movement and "Position". Anything with position is to the SCC. Linear acceleration (movement) regulatory work of the U&S shouldn't be confused with the linear movement of head. The work of the U&S come into play let's say you try to walk on a log of wood, you keep tilting and you keep balancing yourself: That's U&S.

the question is from Jamb pack, it is not specific, or let me say not well constructed

Which of the following food chain is in the correct sequence? A. Weeds → Tadpole → Beetles → Fish → Man B. Weeds → Tadpole → Fish → Beetles → Man C. Tadpole → Beetles →Weeds → Man → Fish D. Man → Fish → Beetles → Tadpole → Weeds E. Fish → Beetles → Weeds → Man → Tadpoles

Pls, Does Uniben accept O level result at two sittings for med&surg??

E. Fish → Beetles → Weeds → Man → Tadpoles

i think the answer to the question should be A.
Weed first because its autotrophic, hence the producer.
Tadpole, the first consumer. Then beetles, fish and then man.
But the qualm i have therein is that of the beetle been the second consumer in the option instead of tadpoles and vice versa . Because there tends to be a more closer connection between beetle as an insect and weeds. And i don't see beetles eating tadpoles.
So i actually think there probably might have been a mistake. I think beetles ought to have come first before tadpole.
#stand to be corrected tho

Thanks for your contribution, the beetle might be a giant aquatic one that can eat up tadpoles, if it could eat tadpoles it can as well eat small fishes.....in the question, the type of fish is not emphasized, it might be tiny fishes that can be devoured by the beetle.....Confuse now, I don't understand the people that sets Jamb questions. Smh

jorrn:

Hahaha...I think if it was to be a small fish, the question would have specified as in the case of 'tadpole'.Moreover, it is more likely for a man to feed on fish than on weeds, tadpole or beetle. So fish has to immediately precede man to make it more rational. So I also go with option A

exactly bro! And wonderfully, i just confirmed that larvae of beetles feed on tadpoles.
Therefore, i think it's beyond all doubt that A is the right answer. abi

Hello please is it possible to do change of course from biochemistry to medicine at uil after 100 level?

Guys pls can one use A Levels to get admission for mbbs through DE? Where can one do A Level?

heykims:

Welldone bros, but I have issues with these your topics
1. Factors Influencing the Preference of Medically Qualified Over Non-Medically Qualified Teachers in Nigerian Medical Schools - did u expect non-medically qualified individuals to be employed as lecturers in medical schools in the first place, is it even a valid question?

2) Prevalence of Stress Among Students: A Comparative Study Between Medical Students and Non-Medical Students in Nigeria Universities- Stress isn't a definitive diagnosis in medicine, I believe definitive health conditions like anxiety disorders, depression with standard criteria for diagnosis should be used.
I don't know if u are a doctor or not but I think your topics require more scrutiny.

Thank you sir.
sorry I've had a busy week else I would have replied earlier.

As for the first study, the ikevin has said it all. I had thoughts of restricting the study to the Preclinical population but frankly we still have non-medically qualified teachers with PhDs teaching clinical students in medical schools.

Example of this is in courses like Medical Microbiology, Clinical pharmacology, Chemical Pathology and Community Medicine(esp occupational health, nutrition and dietetics) where a PhD in any of these fields suffice as employment criteria. The implications of these are obvious.

Thanks for ur thoughts on the second topic. Prevalence is not only used to study a disease. According to Wole Alakija in "Community Health, Primary Health Care and Health Management " Chapter 3 p(17) prevalence is the rate which shows the risk of acquiring a disease or characteristic at a given point or within a period. My lecturers strongly insist that prevalence is not restricted to disease but also conditions that affect a population. You were right about stress not being a diagnosis like tb, hiv etc. But like ikevin mentioned parameters supported by previous studies can be used to know what's going on in our population.

My topics and work is vetted and supervised by someone who has had specialist experience in research for a number of years.

I really appreciate ur input and I look forward to more of it as time goes on.

Uno, it's easy for us to stay here on Nairaland and complain of the system and how terrible it is. What I'm trying g to do is to be objective about these issues so they can serve as a reference for anyone that chooses to support the cause of medical education in Nigeria in the interest of medical students.

I really appreciate

Alright chief, I wish u all the best.

Is there any AAUA medical student in this room?

mctifey:

Where can one do A Level?

Of course....just look for schools around u dat do....it may be secondary or a sixthform college. Some polys do too.

Hmmm. Good evening sirs, does UI, UNILAG, ABU and UNILORIN accept a degree in plant biology for MBBS?

This question may sound weird and i dont really know how to put it,
Since whatever we see with our eyes are inverted, therefore does it mean the real world around us is inverted and the eye makes it look upright or are we upside down and the force of gravity is keeping us stablestable.
I hope you all understand the question and give me positive feedbacks.

Whatever we see with our eyes actually only appear inverted in the retina which is like the photographic film of the eye. It is the brain that later interprets it and we see it the normal way it is. So, in a simple way, it is the eye that makes what we see appear inverted and d brain later 'corrects' the inversion and makes us see things the real way they are.
Is this explanation simple enough?

Your question is quite lucid and thoughtful.
Just like the first guy wrote, it is actually not the eye that makes an object looks upright, it is the function of the brain. The image of every object we see with our eyes is focused on the retina as inverted both laterally and from up to down. The information is sent to the brain in this form so that the brain will do the correct interpretation. This means that without the brain to perform this function, every object will appear to be inverted. Therefore, the real world around us is not inverted but is just the way we see it because our brains have learnt to interpret the images of objects the way the objects really are.

good morning everyone I have two questions to ask. Please I need authentic answers and clarifications.

1. I am a jambit aspiring for medicine but am so confused because I don't know d particular university to choose. I really need a university dat is fair in there admission process. I don't want university dat allocate more quote to indigen and lesser quota to non indigen dat means state owned universities are ruled out. my question now is.. which of the Federal universities in Nigeria is very fair in medicine admission process and its not among d most sort after institution. I have heard lots of medical students say dat dia admission was pure and dia state is not among the university catchment area. ..and I hav been asking for d secret of such success. Still no tangible answers.

2. presently I am undergoing an A level program called IJMB I hav checked online to see universities dat accept it for medicine admission and d particular point dat is required by d universities. I saw universities like: unilorin Requires minimum of 13pts in IJMB for Medicine. Ahmadu Bello university (A.B.U). Accepts 10pts and above for Medicine. in Unijos 8pts and above is required for any course in college of Medicine. unizik- 6pts into Faculty of Medicine and all northern universities accepts IJMB.
I don't know how authentic dis is...Please I will like to hear from the horse's mouth. I believe that dis is d only thread I can get real information concerning medical institutions becos most people hear are experienced. thanks in anticipation.

I have another question,
Why do hospitals ask for police report before treating a gunshot injury instead of saving the life of the patient first?
A lot of people have died due to this kind of thing
I thought the doctors took an oath
