Examples of Starvation in the following topics:

  • Starvation-Induced Fruiting Bodies

    • Starvation-induced fruiting bodies can aggregate up to 500 micrometres long and contain approximately 100,000 bacterial cells.
  • Activation of Starvation by Survival Genes

    • Stringent Response, also called stringent control, is a stress response that occurs in bacteria and plant chloroplasts in reaction to amino-acid starvation, fatty acid limitation, iron limitation, heat shock, and other stress conditions.
  • The Endocrine System and Hunger

    • Starvation is a severe deficiency in caloric energy, nutrient, and vitamin intake.
    • Prolonged starvation can cause permanent organ damage and, untreated, leads to death.
    • Vitamin deficiency, diarrhea, skin rashes, edema, and heart failure are also common results of starvation.
    • In a state of starvation, other motivators—such as the desire for sleep, sex, and social activities— decrease.
    • Individuals suffering from starvation may experience irritability, lethargy, impulsivity, hyperactivity, and more apathy over time.
  • Sporulation in Bacillus

    • Sporulation is the last-ditch response to starvation; it is suppressed until alternative responses prove inadequate.
    • Although sporulation in B. subtilis is induced by starvation, the sporulation developmental program is not initiated immediately when growth slows due to nutrient limitation.
    • Sporulation is a last-ditch response to starvation, and it is suppressed until alternative responses prove inadequate.
  • Hunger, Malnutrition, and Family

    • Those with weak support structures are more vulnerable to hunger and starvation than those with strong family networks.
    • Two terms frequently associated with hunger are "famine" and "starvation. " Famine is the widespread scarcity of food, and it is usually accompanied by regional malnutrition, starvation, epidemic, and increased mortality.
    • Starvation describes a state of exhaustion of the body caused by lack of food and may be fatal.
  • The Stringent Response

    • The stringent response is a stress response that occurs in bacteria in reaction to amino-acid starvation or other stress conditions.
    • The stringent response, also called stringent control, is a stress response that occurs in bacteria and plant chloroplasts in reaction to amino-acid starvation , fatty acid limitation, iron limitation, heat shock, and other stress conditions.
  • Global Aging

    • Much of the higher death rates in poorer nations is due to war, starvation, infant deaths, diseases, and lack of access to adequate health care.
    • The presence of one risk factor is often related to another—war torn countries, for example, are likely to have more instances of starvation.
    • Likewise, people with diseases may have a difficult time getting or sustaining a job, making them vulnerable to starvation.
  • Protection

    • The skin helps protect our body’s internal structures from physical, chemical, biological, radiological, and thermal damage as well as damage from starvation and malnutrition.
    • It acts as a food source, protecting our body from the effects of starvation.
  • Proteins: Sources, Uses in the Body, and Dietary Requirements

    • This use of protein as a fuel is particularly important under starvation conditions as it allows the body's own proteins to be used to support life, particularly those found in muscle.
    • Extreme protein intake (in excess of 200g per day), coupled with inadequate intake of other calorie sources (fat or carbohydrates), can cause a form of metabolic disturbance and death commonly known as rabbit starvation.
  • Casualties of World War II

    • Some 75 million people died in World War II, including about 20 million military personnel and 40 million civilians, many of whom died because of deliberate genocide, massacres, mass-bombings, disease, and starvation.
    • Many of the civilians died because of deliberate genocide, massacres, mass-bombings, disease, and starvation.
