Understanding Infectious Diseases: From Chikungunya to Nosocomial Infections
Understanding Infectious Diseases
Chikungunya
Chikungunya is a viral disease transmitted by infected mosquitoes, causing symptoms like severe joint pain, fever, muscle pain, headache, and rash. While rarely fatal, joint pain can persist for months. Prevention involves mosquito control and personal protection measures.
Swine Flu (H1N1)
Swine flu, or H1N1 flu, is a respiratory disease with symptoms similar to seasonal flu. While most cases are mild, complications can occur. Vaccination and good hygiene

Write a note on ribosomes
Ribosomes are cellular organelles responsible for protein synthesis, a crucial process in all living cells. These small, complex structures are found in the cytoplasm of prokaryotic and eukaryotic cells.
Ribosomes exist in two main forms: free ribosomes, which are suspended in the cytoplasm, and bound ribosomes, which are attached to the endoplasmic reticulum.
The primary function of ribosomes is to translate genetic information from messenger RNA (mRNA) into proteins. This

Eye Drops
Ophthalmic preparations, commonly known as eye drops, are sterile solutions or suspensions used for eye treatment. They can be administered as drops, sprays, or ointments.
Types of Ophthalmic Preparations:
- Eye drops
- Eye ointments
- Contact lens solutions
Factors Affecting Eye Drop Formulation:
- Sterility
- Pain and irritation
- Antimicrobial activity
- pH adjustment
- Viscosity
- Isotonicity with tears
- Volume
How to Use Eye Drops:

Circulatory & Excretory Systems: Functions & Diseases
Circulatory System
Lymphatic System
The lymphatic system maintains body fluid balance and defends against infections.
- Lymph capillaries: Collect excess interstitial fluid.
- Lymphatic vessels: Return excess lymph to the circulatory system.
- Lymph nodes: Contain defense cells for fighting infection.
- Lymph: Acts as an intermediary in nutritional exchanges between blood and tissues.
Blood Circulatory System
The blood circulatory system defends against infections, facilitates gas exchange, and transports nutrients.

Amino Acids and Proteins
Amino Acid Structure
Amino acids are the building blocks of proteins. They have a central carbon atom (alpha carbon) bonded to an amino group (-NH2), a carboxyl group (-COOH), a hydrogen atom, and a variable side chain (R group). The R group determines the unique properties of each amino acid.
Peptide Bonds and Protein Structure
Peptide bonds link amino acids together to form peptides and proteins. Proteins have four levels of structure:
- Primary structure: The linear sequence
