Imaging Studies VII: Vascular Imaging

371
DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...

Area of Science:

  • Cell Biology
  • Molecular Biology
  • Developmental Biology

Background:

  • SNAP-29 is a protein expressed throughout the fruit fly life cycle.
  • Unlike other SNAP-25-like proteins, SNAP-29 regulates intracellular trafficking, not just plasma membrane exocytosis.
  • It partners with proteins involved in both exocytosis and endocytosis.

Purpose of the Study:

  • To describe a protocol for localizing SNAP-29 in fruit fly models.
  • To facilitate the study of SNAP-29's role in intracellular trafficking.

Main Methods:

  • Immunofluorescence microscopy
  • Localization studies in fruit fly early embryos
  • Localization studies in third instar larval imaginal discs
  • Localization studies in immortalized S2 cells

Main Results:

  • A reliable protocol for SNAP-29 immunofluorescence localization was established.
  • SNAP-29 can be localized in various fruit fly developmental stages and cell types.

Conclusions:

  • The described protocol enables precise localization of SNAP-29.
  • This method supports further investigation into SNAP-29's diverse roles in intracellular transport.
