Deadly calcium influx could be one way TSP-1 kills red blood cells and promotes disease

Rating
0.0 stars

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Thrombospondin-1, or TSP-1, is a calcium-binding protein implicated in the development of several diseases, including diabetes, cancer, renal failure, and cardiovascular disease. To understand TSP-1’s role in disease, researchers recently examined the protein’s effects on the calcium dynamics, survival, and deformability of red blood cells. In vitro experiments showed that exposure to recombinant human TSP-1 significantly increased calcium levels in red blood cells. TSP-1 treatment also induced an inward ionic current, suggesting possible calcium influx through non-selective cation channels, and TSP-1 caused the deformation of red blood cells. Further experiments revealed that TSP-1 binding to its receptor CD47 could dictate the lifespan of red blood cells in circulation. Altogether, the findings suggest that TSP-1/CD47 signaling could be one targetable pathway in systemic diseases that attack red blood cells..."

Students learn about the form and function of the human heart through lecture, research and dissection. They brainstorm ideas that pertain to various heart conditions and organize these ideas into categories that help them research possible solutions. An expert in the field of cardiac valve research was interviewed for this lesson and shares his ideas with the class. Students conclude by researching various possible heart defects.

Rating
0.0 stars

The overall purpose of this preparatory course textbook is to help students familiarize with some terms and some basic concepts they will find later in the Human Anatomy and Physiology I course.

The organization and functioning of the human organism generally is discussed in terms of different levels of increasing complexity, from the smallest building blocks to the entire body. This Anatomy and Physiology preparatory course covers the foundations on the chemical level, and a basic introduction to cellular level, organ level, and organ system levels. There is also an introduction to homeostasis at the beginning.

This activity was designed for blind learners, but all types of learners can use it to learn how the body self-regulates. This lesson plan teaches students how the human body self-regulates to maintain a stable internal environment despite changes in the external environment -- a process called homeostasis. Most of the activities detailed in this lesson plan can be done with visually impaired students if teachers adapt them using Resources for Teaching and Adapting Lessons for Students with Visual Impairments.

This interactive simulation of human homeostasis provides students the opportunity to explore how our body maintains a stable internal environment in spite of of the outside conditions, within certain limits. This simulation allows students to investigate a phenomenon that may in real life, be dangerous to humans. Students are asked to regulate the internal body temperature of an individual using clothing, exercise, and perspiration. A four- page exploration sheet guides students through the simulation, including a short prior knowledge piece providing information on how to use the simulation and introductory questions. Two separate activities are included: one that helps students understand the how each external factor affects initial body temperature and another that allows students to explore effects on body temperature after one hour. In the second portion of the interactive simulation students try to maintain a stable body temperature when the factors are changed. Students choose the factors of exercise level, sweat level, body position, clothing, and nutrients in terms of both water and food to maintain homeostasis. The simulation generates data tables and graphing during specific time intervals of outside temperature and body temperature. Students may also alter the outside temperature as part of the simulation. Students adjust the exercise level, amount of clothing, and sweating levels. Water level, sugar level, and fatigue level are influenced by the students’ choices and are illustrated by bar graphs and line graphs. This simulation can provide an introduction to a lesson or unit that explores how body systems interact. This simulation provides a good foundation for continued study of how the body systems interact and would be an excellent starting point for a lesson or unit on this concept. This interactive simulation provides students with a strong introduction to how body systems interact as the simulation illustrates how to maintain body temperature, sugar level and fatigue level and students are made aware of the consequences of not maintaining those levels. The importance of water and food are also emphasized. Students can rerun the simulation making different choices to determine the effects on homeostasis. Student exploration sheets provide guides for different runs with students setting their own parameters for the runs and drawing conclusions from the resulting changes. Teachers can view student assessment responses by assigning the simulation to a class created within the ExploreLearning site. Access to the teachers guide is provided with the free 30 day access and is helpful and complete. Vocabulary of dehydration, heat stroke, homeostasis, hypothermia, and involuntary, voluntary and thermoregulation are explained in detail in the accompanying teacher’s vocabulary guide.

It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Inflammatory bowel diseases (IBDs), such as Crohn’s disease and ulcerative colitis, affect more than 0.3% of the Western population. The sheer complexity of these diseases presents a major challenge to treatment, as it has created a disconnect between microbiologists studying the effects of the microbiome, immunologists studying immune responses, and clinicians who treat individuals with IBD. To mount a more holistic approach, researchers recently examined the crosstalk between immune cells and bacteria in the colon. Experiments revealed the significance of bacterial products called outer membrane vesicles, or OMVs. OMVs are tiny sacs of cellular material released by bacteria as a way of communicating with immune cells. In patients with Crohn’s disease or ulcerative colitis, OMVs elicited only a small fraction of their normal immune response, suggesting a breakdown in immune–microbiota communication..."

Just Like Kidneys: Semipermeable Membrane Prototypes
Read the Fine Print
Educational Use
Rating
0.0 stars

Using ordinary household materials, student “biomedical engineering” teams design prototype models that demonstrate semipermeability under the hypothetical scenario that they are creating a teaching tool for medical students. Working within material constraints, each model consists of two layers of a medium separated by material acting as the membrane. The competing groups must each demonstrate how water (or another substance) passes through the first layer of the medium, through the membrane, and into the second layer of the medium. After a few test/evaluate/redesign cycles, teams present their best prototypes to the rest of the class. Then student teams collaborate as a class to create one optimal design that reflects what they learned from the group design successes and failures. A pre/post-quiz, worksheet and rubric are provided.

"Mesenchymal stromal cells, or MSCs, regulate many functions critical to maintaining organ health. They do so by sending and receiving biochemical signals across short and long distances. How this signaling function is altered by disease, however, remains unclear. In a recent study, researchers examined how obesity in mice affects the signaling functions of MSCs from fat tissue and bone marrow. The proteins secreted by MSCs in mice fed a normal diet play a role in detoxification activity in response to toxic substances and drugs. They are also involved in bone, cartilage and fat development. Further analyses revealed that mouse MSCs participate in two major signaling pathways: platelet degranulation, where signaling molecules wrapped up in granules are deployed to regulate blood clotting and inflammation; and the insulin-like growth factor pathway, which regulates cell proliferation, survival, and metabolism. Comparing proteins secreted by MSCs in normal vs. obese mice revealed key differences..."
