Alternative RNA Splicing02:18

Alternative RNA Splicing

25.2K
Alternative RNA splicing is the regulated splicing of exons and introns to produce different mature mRNAs from a single pre-mRNA. Unlike in constitutive splicing where a single gene produces a single type of mRNA, alternative splicing allows an organism to produce multiple proteins from a single gene and plays an important role in protein diversity.
There are five types of alternative RNA splicing that vary in the ways the pre-mRNA segments are removed or retained in the mature mRNA. The first...

Null and Alternative Hypotheses01:16

Null and Alternative Hypotheses

12.8K
The actual hypothesis testing begins by considering two hypotheses. They are termed  the null hypothesis and the alternative hypothesis. These hypotheses contain opposing viewpoints.
The null hypothesis, denoted by H0 is a statement of no difference between the variables—they are not related. This can often be considered the status quo. As  a result if you cannot accept the null, it requires some action.
The alternative hypothesis, denoted by H1 or Ha, is a claim about the...

Electric Generator: Alternator01:25

Electric Generator: Alternator

3.4K
Electric generators induce an emf by rotating a coil in a magnetic field. A simple alternator is an AC generator that creates electrical energy that varies sinusoidally with time. A simple alternator consists of a conducting loop that is placed inside a uniform magnetic field. The loop is connected to split rings connected to the external circuit with the help of brushes.
The magnetic flux passing through the coil varies sinusoidally as the loop rotates inside the magnetic field. This...

Buffer Effectiveness02:19

Buffer Effectiveness

55.5K
Buffer solutions do not have an unlimited capacity to keep the pH relatively constant . Instead, the ability of a buffer solution to resist changes in pH relies on the presence of appreciable amounts of its conjugate weak acid-base pair. When enough strong acid or base is added to substantially lower the concentration of either member of the buffer pair, the buffering action within the solution is compromised.
The buffer capacity is the amount of acid or base that can be added to a given volume...

Framing Effects03:26

Framing Effects

8.0K
Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

Summary

Rotablation effectively treated underexpanded stents in a patient with recurrent angina, achieving full stent deployment. This intervention led to sustained symptom relief and an excellent angiographic outcome at one year.

Area of Science:

  • Interventional Cardiology
  • Cardiovascular Interventions

Background:

  • Recurrent angina can significantly impact quality of life.
  • Underexpanded stents pose a challenge in achieving optimal treatment outcomes.
  • Conventional methods may not always suffice for complete stent deployment.

Observation:

  • A 75-year-old female presented with recurrent angina.
  • The patient had a previously implanted underexpanded stent.
  • Standard angioplasty techniques failed to achieve full stent expansion.

Findings:

  • Rotablation was employed as a treatment strategy.
  • The procedure resulted in an excellent angiographic outcome.
  • Complete stent deployment was successfully achieved.

Implications:

  • Rotablation is a viable option for managing underexpanded stents.
  • Successful stent expansion can lead to long-term angina relief.
  • This case highlights the utility of rotational atherectomy in complex coronary interventions.
