Class,
Please note that for those on 6-months attachment, do ask your supervisor to fill in the first column (individual assessment) on page 37 of your log book.
This individual assessment is different from the online evaluation form that will be sent to them at the end of Aug.
Regards,

Evaluation Matters
Class,
For those on 6 months attachment with FYP, the online evaluation form will be emailed to your respective supervisor at the end of the 6 months attachment, which means it will be around the period of August. Students will have no access to it.
As for those who have finished their 3 months of attachment, I'm sure the online evaluation has been sent to your respective supervisors too.

NAPFA Test
MB0505
NAPFA TEST
19 Jul 2007
Wednesday
5.30 pm
Students are to report 10 mins prior to their test time at Blk G Room 312 for their attendance to be taken. All students must be in proper track and field attire.
Students who have chronic medical conditions are to submit their doctor's letter(s) (CMPB letter for NS-eligible males) directly to the SAO to be excused from NAPFA.
For those who would like to have training sessions, kindly contact Seng Kiong.
Students who will be on overseas attachment will have their test date rescheduled when they return.
NAPFA is compulsory for all registered students of NYP (males, females, Singaporeans, international students). The results will be reflected on their transcript.

InImm Revision
I believe some of us are still confused about what exactly is intracellular, extracellular bacteria. So here's my 2 cents worth.
OVERVIEW
Example: bacteria toxin
How our immune system is evoked.
Example: viruses
How our immune system is evoked.
OVERVIEW
- Bacteria/toxin/viruses attach on the surface of a macrophage.
- Taken into macrophage via endocytosis.
- Vesicle is formed inside the macrophage. (another name for vesicle is phagosome)
- If the phago-lysosome fusion is able to take place, bacteria is called a EXTRACELLULAR bacteria. If the fusion is unable to take place, bacteria is called an INTRACELLULAR bacteria. If the virus manage to penetrate the vesicle to enter into the cytoplasm without the fusion process, it is a FREE-FLOATING CYTOPLASM.
INTRACELLULAR BACTERIA (Example: TB)
How our immune system is evoked.
- Endocytosis of bacteria cell into macrophage.
- Fusion of vesicle and lysosome is triggered.
- As the fusion is prevented, IL-12 is released by macrophage.
- Antigens are processed and presented as MHC Class 2.
- APC cell talks to a CD4+ T cell.
- IL-12 released by macrophage stimulate CD4+ to differentiate into TH1 t cells.
- Activated TH1 cell activates macrophage, makes it more aggressive, forces fusion to occur.
- Once fusion has occured and downstream processes is carried out, IL-4 is released by macrophage.
- IL-4 activates TH0 T cell into TH2 T cell.
- TH2 T cell activates B cell, makes them proliferate and produce antibodies.
- Antiobodies will target those intracellular bacteria present outside the cell. (read up on functions of Antibodies)
Example: bacteria toxin
How our immune system is evoked.
- Endocytosis of bacteria cell into macrophage.
- Fusion of vesicle and lysosome is triggered.
- After digestion of bacteria, IL-4 is released by macrophage.
- Antigens are processed and presented on MHC Class 2.
- APC cell talks to a CD4+ T cell.
- IL-4 released by macrophage stimulates TH0 into TH2 T cells.
- TH2 T cell activates B cell, makes them proliferate and produce antibodies.
- Antiobodies will target those intracellular bacteria present outside the cell. (read up on functions of Antibodies)
Example: viruses
How our immune system is evoked.
- Endocytosis of bacteria cell into macrophage.
- Viruses manage to penetrate through vesicle and enters cytoplasm.
- Antigens are processed and presented as MHC Class 1 molecules.
- APC cell talks to CD8+ T cell.
- CD8+ T cell is activated and lyse cell via perforins or FasL.
Best of luck!

Section B - Short Answer Questions 80 Marks
Section A - MCQs (Week 1 to Molecular Modelling) 20 Marks
Section B - Short Answer Questions 80 Marks
- 1 Question from Adrian
- 2 Questions from L.T
- 3 Questions from William
L.T Topics
1. Protein Analysis - Multiple Sequence Alignment
- identify similar areas
- how to use?
- weaknesses?
- information that can be derived
2. Genome Analysis - comparative analysis / genome of simple organism
3. Nucleotide Analysis - gene finding alogrithm (GenScan / MZEF)
- BLAST - similarity & identity
- the different tools under BLAST
- ORF - conceptual translation
Willam How's Topics
- Primary and secondary database
- Definitions and examples
- Elaborate on the different databases
- GenBank - nucleotide / annotation / variable DNA sequence (Partial genes, complete genes, complete genome)
- How is secondary information derived from primary?
- Explain the different forms of classification.
Jia You!
