Tumor Progression02:07

Tumor Progression

7.4K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Gene Therapy00:59

Gene Therapy

27.6K
Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

4.8K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Group Therapy01:26

Group Therapy

450
Group therapy is a sociocultural approach to psychological treatment, where individuals with shared psychological challenges come together under the guidance of a mental health professional. This therapeutic modality offers unique opportunities for individuals to connect, share, and grow within the context of a supportive group. By fostering mutual understanding and collaboration, group therapy can address a range of psychological concerns effectively, often complementing or surpassing the...

Regulation of Stroke Volume01:27

Regulation of Stroke Volume

5.2K
The regulation of stroke volume, which is the amount of blood the heart pumps out during each heartbeat, is critical for maintaining a healthy circulatory system. Stroke volume is influenced by three main factors: preload, contractility, and afterload.
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...

Imaging Studies I: CT and MRI

901
Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Area of Science:

  • Neurology
  • Radiology
  • Medical Imaging

Background:

  • Revascularization is key for acute ischemic stroke, but many patients are ineligible or treatments fail.
  • Non-contrast CT is the current standard for initial stroke imaging.
  • Advanced neuroimaging is needed to optimize treatment selection and outcomes.

Purpose of the Study:

  • To review the role of magnetic resonance imaging (MRI) in acute ischemic stroke.
  • To explore MRI's potential in predicting response to revascularization therapies.
  • To discuss advances in MRI-based patient triage for stroke treatment.

Main Methods:

  • Review of recent advances in neuroimaging and revascularization strategies.
  • Discussion of MRI techniques for assessing stroke pathophysiology (ischemic core, perfusion, collaterals, clot, blood-brain barrier).
  • Exploration of post-processing and machine-learning applications in MRI analysis for stroke.

Main Results:

  • MRI provides comprehensive pathophysiological information crucial for stroke management.
  • Advanced MRI techniques can identify patients who may benefit from early or delayed revascularization.
  • Machine learning enhances MRI's utility in stroke triage and treatment response prediction.

Conclusions:

  • MRI is a valuable tool for optimizing acute ischemic stroke treatment selection.
  • Integrating advanced MRI and machine learning can improve patient outcomes in stroke care.
  • Further research into MRI-based triage strategies is warranted for acute ischemic stroke.
