Understanding Lipid Metabolism: From Digestion to Diseases

Q. Choose True:

– Two classes of phospholipids contain sphingosine and glycerol as a backbone.

– Both classes are found as structural components of membranes and play a role in the generation of lipid signaling molecules.

Ethanolamine + PA = Cephalin

Choline + PA = Lecithin

Q. Two molecules of PA esterified through their phosphate group to glycerol is called:

Cardiolipin

Q. The backbone of sphingomyelin is the amino alcohol:

Sphingosine

Q. The precursor of many other phosphoglycerides is:

Phosphatidic acid

The Risks and Benefits of Cosmetic Surgery

Introduction

For modern people, cosmetic surgery has become increasingly popular. Some believe it is a technique to enhance beauty. The basic intention of this surgery is to enhance an individual’s appearance by changing body parts. On the other hand, others disagree, saying that cosmetic surgery can pose a risk of serious diseases such as a heart attack.

Understanding Inflammation, Neoplasms, and Cancer Prevention

Pathogenesis of Inflammation

Vascular Changes

Vasodilation occurs, increasing blood flow and causing congestion. Dilated capillaries become more permeable, leading to fluid leakage and potential bleeding.

Cellular Changes

Leukocytes adhere to vessel walls (margination) and then migrate through the endothelium (diapedesis) to the infection site. They engulf and eliminate foreign particles and pathogens through phagocytosis.

Tumor Changes

Accumulation of water, acids, and fibrinogen at the injury site causes

Understanding Illness: Types, Phases, and Reactions

The Nature of Illness

The lack of health may cause a certain level of dependency. A human being is multidimensional, encompassing biological aspects (physical structure), physical processes (emotions, feelings), and social aspects (relationships, social settings).

Disease is a deviation from the state of health with objective and subjective manifestations, which diminishes a person’s ability to carry out daily life activities. It can manifest in various ways depending on the disease (severe, infectious,
