02:11Reporter Genes
13.6K
Reporter genes are a type of protein-coding gene that are often tagged to a gene of interest. Once inside a target cell, reporter genes usually produce visually identifiable characteristics like fluorescence and luminescence when expressed along with the gene of interest. Thus, reporter genes “report” the presence or absence of genes of interest in an organism, determine the gene expression pattern, or track the physical location of a DNA segment or protein in the cell.

Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?

The discussion of bullying highlights the problem of witnesses not intervening to help a victim. This is a common occurrence, as the following well-publicized event demonstrates. In 1964, in Queens, New York, a 19-year-old woman named Kitty Genovese was attacked by a person with a knife near the back entrance to her apartment building and again in the hallway inside her apartment building. When the attack occurred, she screamed for help numerous times and eventually died from her stab wounds.

01:15The Antenna Complex
8.3K
Plants and other photosynthetic organisms comprise pigments capable of absorption of direct sunlight. These pigments are present in the reaction center - the main site of photochemical reactions as well as in the antenna complex. Under average light conditions, the rate at which reaction center pigments absorb light is far below the electron transport chain's capacity. As a result, the reaction center alone cannot provide enough energy to drive photosynthesis. The photosynthetic efficiency can...

01:24Data Reporting and Recording
5.6K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

01:24Back EMF
4.7K
Generators convert mechanical energy into electrical energy, whereas motors convert electrical energy into mechanical energy. A motor works by sending a current through a loop of wire located in a magnetic field. As a result, the magnetic field exerts a torque on the loop. This rotates a shaft, extracting mechanical work from the electrical current sent in initially. When the coil of a motor is turned, magnetic flux changes through the coil, and an emf (consistent with Faraday's law) is...

Summary
Creutzfeldt Jakob disease (CJD) is not the same as mad cow disease in humans. While both are fatal brain diseases, they have different causes and transmission routes.
Area of Science:
- Neurology
- Infectious Diseases
- Prion Diseases
Background:
- Media reports often equate Creutzfeldt Jakob disease (CJD) with 'mad cow disease'.
- This simplification overlooks critical distinctions between these fatal neurodegenerative conditions.
Purpose of the Study:
- To clarify the relationship between Creutzfeldt Jakob disease and bovine spongiform encephalopathy (mad cow disease).
- To differentiate the causes, transmission, and human health implications of CJD and its variants.
Main Methods:
- Review of scientific literature on prion diseases.
- Comparative analysis of CJD and bovine spongiform encephalopathy (BSE) epidemiology and pathology.
- Examination of transmission pathways in humans and animals.
Main Results:
- Creutzfeldt Jakob disease (CJD) is a rare human prion disease with several forms (sporadic, genetic, acquired).
- Bovine spongiform encephalopathy (BSE) is a prion disease affecting cattle.
- The human form linked to BSE is variant Creutzfeldt Jakob disease (vCJD), distinct from classical CJD.
Conclusions:
- Creutzfeldt Jakob disease and mad cow disease are not synonymous.
- Understanding the specific nature of CJD and vCJD is crucial for accurate public health communication and risk assessment.
