New Drug Discovery and Development .....NEHA GUPTA
The "New Drug Discovery and Development" process involves the identification, design, testing, and manufacturing of novel pharmaceutical compounds with the aim of introducing new and improved treatments for various medical conditions. This comprehensive endeavor encompasses various stages, including target identification, preclinical studies, clinical trials, regulatory approval, and post-market surveillance. It involves multidisciplinary collaboration among scientists, researchers, clinicians, regulatory experts, and pharmaceutical companies to bring innovative therapies to market and address unmet medical needs.
Title: Sense of Smell
Presenter: Dr. Faiza, Assistant Professor of Physiology
Qualifications:
MBBS (Best Graduate, AIMC Lahore)
FCPS Physiology
ICMT, CHPE, DHPE (STMU)
MPH (GC University, Faisalabad)
MBA (Virtual University of Pakistan)
Learning Objectives:
Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path
The Gram stain is a fundamental technique in microbiology used to classify bacteria based on their cell wall structure. It provides a quick and simple method to distinguish between Gram-positive and Gram-negative bacteria, which have different susceptibilities to antibiotics

5. PTC
• PTC, is a way of examining the bile duct system
in the liver.A thin needle is inserted through
the skin (percutaneous) and through the liver
(transhepatic) into a bile duct. Then dye is
injected, and the bile duct system is outlined
on x-rays (cholangiography).
6. PTBD
• A Percutaneous Transhepatic Biliary Drainage
is a percutaneous therapeutic procedure
which leads to the drainage of the obstructed
bile duct system
9. Preparation & procedure
• US/CT prior to PTBD, which provides useful
information regarding the level of obstruction.
• The doctors will take a blood sample and send
this to the laboratory for testing.
• On the day of the examination an intravenous
line will be inserted into an arm vein.
• One hour prior to the examination intravenous
antibiotics will be given through this line.
10. • It is not allowed to eat for four hours before the
examination, but one may drink clear fluids.
• Patient will be given the opportunity to ask
questions about the procedure before signing a
consent form.
• The patient will be asked to lie on his/her back on
an examination table with the right arm away
from the side of your body (above head).
11. • Monitoring equipment will be attached; this
will measure the blood pressure, heart rate
and oxygen saturation.
• The skin will be cleaned with an antiseptic skin
preparation lotion.
• Local anaesthetic will be administered into the
skin.
12. • Once the area is numb, the doctor will insert a thin
needle through your skin, between the ribs,
through the liver, into a bile duct under
fluoroscopy guidance . As the needle is
withdrawn, a small amount of dye will be injected
and x-rays will be taken.
• If the PTC results show a problem, such as a
blockage in the bile duct, the doctor may replace
the thin needle with a small drainage tube
(catheter) .A small pouch may be attached to the
end of the catheter outside your body to collect
bile.
15. • The blood pressure and pulse will be monitored.
• The Haematocrit will be checked.
• The catheter site will be checked frequently.
• Patient can eat and drink normally, or as
instructed by the Doctors.
• He/she must be careful not to dislodge the
catheter
