Chapter 13, Problem 13.7PS

(a)

Summary Introduction

To determine: What happens to the cells when injected with large amounts of purified gelsolin.

Introduction: Gelsolin is a member of a family, villin. Gelsolin is a protein which binds to the actin filament and helps in its assembly and disassembly.

(b)

Summary Introduction

To determine: What happens to the cell when cells treated with latrunculin A, and the drug is washed out.

Introduction: Latrunculin A is a drug, extracted from the Latrunculia magnifica, which is a Red Sea Sponge. This drug affects the polymerization of microfilaments.

(c)

Summary Introduction

To determine: The direction of the point of arrowhead-shaped decorations, in which the cells are treated with a chemical fixative and prepared for electron microscopy.

Introduction: Chemical fixatives are used to fix the structures in a state by preventing its biochemical reactions. Fixation is the crucial step in sample preparation for microscopy.

Please help me with this question. PLEase give me the right answer and for number 2 WRITE AT LEAST A PARAGRAPGH and dont copy from internet.
Hello, good day. I have a problem answering this question, and I need your help. Hoping for a response, and thank you so much. Instruction: The answer must be in a minimum of 2 paragraphs, and each paragraph must have a minimum of 4 sentences.  Question: Research have stated that there are factors that could affect the efficacy and duration of mosquito repellants on our skins. State at least 3 factors that could decrease or influence the efficacies of topical mosquito repellants.
Cold-Reacting Autoantibodies.  Most adult sera contain low titers of cold-reacting autoantibodies, most notably autoanti-I, autoanti-H, and autoanti-IH. These antibodies are usually IgM and of no clinical significance. They are troublesome in that they may interfere with the detection of significant antibodies, resulting in prolonged workups and delayed transfusions.Cold-reacting autoantibodies may be suspected when the screen cells, panel cells, and the autocontrol areall positive at the immediate spin phase and reactivity gets weaker or disappears with incubation at 37°C (Fig. 9–18).Certain cold autoantibodies activate complement and may be detected at the AHG phase when using complement-containing AHG reagent. These autoanti- bodies may be mistaken for weakly reacting IgG antibodies.Although it is not usually necessary to determine the specificity of the cold autoantibody, testing against additional cells may confirm its presence. Cord blood cells that lack the I antigen are of…
