HIV and Retroviruses
Retroviruses are RNA viruses that reverse-transcribe their genome into DNA and integrate into the host chromosome, with HIV being the most clinically important member.
BiologyViral Diagnostics and Detection
Viral diagnostics encompasses a range of techniques for detecting and identifying viruses in clinical samples, including molecular, serological, and culture-based methods.
Biology
Cell Membrane Structure and Transport
The cell membrane is a selective permeability barrier composed of a phospholipid bilayer with embedded proteins, controlling the passage of molecules via passive and active transport mechanisms.
BiologyThe Endomembrane System and Protein Trafficking
The endomembrane system is a network of membrane-bound organelles that synthesize, modify, sort, and transport proteins and lipids throughout the eukaryotic cell.
Biology
Chromosome Structure and Organization
Chromosomes are highly organized structures of DNA and proteins that package genetic information and regulate gene expression within the cell nucleus.
BiologyMendelian Genetics and Inheritance Patterns
Mendelian genetics describes the fundamental principles of inheritance through dominant and recessive alleles, segregation, and independent assortment of genes.
Biology
The Complement System
The complement system is a cascade of serum proteins that opsonizes pathogens, recruits inflammatory cells, and directly lyses microbes through the membrane attack complex.
BiologyCytokines and Chemokines
Cytokines and chemokines are small signaling proteins that mediate intercellular communication in the immune system, regulating inflammation, immunity, and hematopoiesis.
BiologyAntiviral Immune Responses
Antiviral immune responses encompass the innate and adaptive mechanisms by which the host detects, restricts, and eliminates viral infections.

Capillary Electrophoresis: Principles and Instrumentation
Capillary electrophoresis is a separation technique that uses narrow capillaries and high-voltage electric fields to separate charged analytes based on their electrophoretic mobility.
ChemistryCapillary Gel Electrophoresis: Size-Based Separation in Polymer Matrices
Capillary gel electrophoresis uses a polymer gel or linear polymer matrix within a fused-silica capillary to separate DNA, RNA, and proteins by molecular size with high resolution.
ChemistryCapillary Isoelectric Focusing
Capillary isoelectric focusing separates amphoteric molecules such as proteins and peptides according to their isoelectric point in a pH gradient established within the capillary.
