Textbook Question
Chapter 24.3, Problem 1CT
Physicians’ Assistants
Another invertebrate animal that has been recruited for medical duty is the blowfly or, more precisely, blowfly larvae, commonly known as maggots (FIG. 24-32). Blowfly maggots have proved to be effective at ridding wounds and ulcers of dead and dying tissue. If such tissue is not removed, it can interfere with healing or lead to infection. Traditionally, dead tissue in wounds is removed by a physician wielding a scalpel, but maggots offer an increasingly common alternative treatment. In this treatment, a bandage containing day-old, sterile maggots is applied to the wound. The maggots consume dead or dying tissue, secreting digestive enzymes that do not harm healthy skin or bone. After a few days, the maggots have grown to the size of rice kernels and are removed. The treatment is repeated until the wound is clean.

- New research suggests a link between some microbes that normally live in the body and seemingly unrelated major illnesses. The gum disease called periodontitis itself is not life-threatening, for instance, but it is a fairly good predictor for heart attacks. Bacteria that cause gum disease can trigger inflammation.

- Malaria disease is characterized by cycles of symptoms with 3 stages; a cold stagewhen you shiver and feel very cold, a hot stage when your fever may reach as high as 41oC (104F) and finally, a sweating stage during which your fever drops rapidly.

The botulism toxin binds to the axon terminal, truly the cytoplasmic membrane of the neuron. The botulism toxin binds to the sarcoplasmic recticulum preventing the release of calcium. The botulism toxin binds to the cytoplasmic membrane of the muscle cell. The botulism toxin binds to the synaptic vessicles preventing the release of acetylcholine. Question 9 What are dental caries? MacBook Airarrow_forwardCystic Fibrosis APPLY WHAT YOU HAVE LEARNED You are a researcher working on a treatment for Hutchinson Gilford progeria syndrome, an extrernely rare genetic disorder that causes accelerated aging in children. Children with progeria generally appear healthy at birth but soon start growing more slowly than other children and lose their hair. Additional symptoms include stiffness of joints, heart problems, and stroke. These children typically die of heart disease at an average age of 13 years. 5. Progeria is caused by a mutation in a single gene, called lamin A. Scientists have identified over 1,400 mutations in the lamin A gene that result in changes in transcription, RNA splicing, and/or protein production. Lamin A codes fora protein required for the structural support of the nuclear envelope in cells. Without a functional protein, the nuclear envelope becomes unstable, eventually damaging the nucleus and causing cells to die, Based on what you learned in this Click & Learn, propose a…arrow_forward
- B. The Strange Case of BeriBeri In 1887 a strange nerve disease attacked the people in the Dutch East Indies. The disease was BeriBeri. Symptoms of the disease included weakness and loss of appetite. Victims often died of heart failure. Scientists thought the disease might be caused by bacteria. They injected chickens with bacteria from the blood of patients with BeriBeri. The injected chickens became sick. However, so did a group of chickens that were not injected with bacteria from the blood of patients with BeriBeri. One of the scientists, Dr. Eijkman, noticed something. Before the experiment, all the chickens had eaten whole-grain rice, but during the experiment, the chickens were fed polished rice. Dr. Eijkman researched this interesting case. he found that polished rice lacked thiamine, a vitamin necessary for good health. 1. State the Problem. 2. What was the hypothesis? 3.
