Spare Receptors01:30

Spare Receptors

4.5K
Some receptors remain unoccupied even when an agonist produces a maximal response. Such empty ones are called spare receptors. In presence of spare receptors the maximum effect of an agonist drug is achieved with fewer than 100% of the receptors being occupied. To determine the presence of spare receptors, scientists often compare the concentration of the drug needed to produce 50% of the maximum effect (EC50) with the concentration of the drug needed to occupy 50% of the receptors (Kd). If the...

Radical Reactivity: Nucleophilic Radicals01:16

Radical Reactivity: Nucleophilic Radicals

2.6K
Radicals adjacent to electron-donating groups are called nucleophilic radicals. These radicals readily react with electrophilic alkenes. The SOMO–LUMO interactions are the driving force for the reaction, where the high-energy SOMO of the electron-rich, nucleophilic radicals interacts with the low-energy LUMO of the electron-deficient, electrophilic alkenes. Such SOMO–LUMO interactions are the basis of reactive radical traps, affecting the selectivity in radical reactions. For...

Radical Reactivity: Electrophilic Radicals

2.4K
Radicals adjacent to electron‐withdrawing groups are called electrophilic radicals. These radicals readily react with nucleophilic alkenes. For example, the malonate radical, in which the radical center is flanked by two electron‐withdrawing groups, reacts readily with butyl vinyl ether, which consists of an electron‐donating oxygen substituent. The reaction between electrophilic malonate radical and nucleophilic vinyl ether is favored because the radical has a...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

420
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Radical Autoxidation01:20

Radical Autoxidation

3.1K
The oxidation of an organic compound in the presence of air or oxygen is called autoxidation. For example, cumene reacts with oxygen to form hydroperoxide. Autoxidation involves initiation, propagation, and termination steps. Many organic compounds are susceptible to autoxidation—especially ethers in the presence of oxygen, which form hydroperoxides. Even though this reaction is slow, old ether bottles contain small amounts of peroxide, which leads to laboratory explosions during ether...

Antihypertensive Drugs: Potassium-Sparing Diuretics01:28

Antihypertensive Drugs: Potassium-Sparing Diuretics

2.2K
Liddle syndrome is a genetically inherited form of hypertension characterized by the overactivity of epithelial sodium channels in the nephron, the functional unit of the kidney. This heightened activity leads to increased sodium reabsorption and excessive excretion of potassium. To counteract this, potassium-sparing diuretics such as amiloride are used. They function by blocking these sodium channels, thereby reducing the influx of sodium into the epithelial cells and minimizing the loss of...

Summary

CT scans before prostate surgery can help surgeons better identify critical arteries and nerves. This may improve recovery of erectile function and continence after robot-assisted radical prostatectomy (RARP).

Area of Science:

  • Urology
  • Surgical Oncology
  • Medical Imaging

Background:

  • Robot-assisted radical prostatectomy (RARP) is a standard treatment for localized prostate cancer.
  • Preserving neurovascular bundles (NVB) is vital for post-operative erectile function and urinary continence.
  • Accurate intraoperative identification of NVB remains a challenge in RARP.

Purpose of the Study:

  • To review the anatomy of the prostate, NVB, and vasculature relevant to RARP.
  • To evaluate the utility of CT prostate angiography (CTPA) in preoperative planning for RARP.
  • To assess CTPA's potential to improve nerve-sparing (NS) RARP outcomes, particularly erectile function.

Main Methods:

  • This is a hypothesis-generating narrative review.
  • The review synthesizes existing literature on prostate anatomy, NVB, vasculature, and RARP techniques.
  • It specifically examines the role of CTPA in visualizing prostatic arteries for surgical planning.

Main Results:

  • Prostatic artery branches can serve as anatomical references for NVB during NS RARP.
  • CTPA offers detailed vascular mapping, potentially aiding in precise prostate artery localization.
  • Improved localization of vasculature may facilitate better NVB identification and preservation during surgery.

Conclusions:

  • CTPA, while used in benign prostatic hyperplasia treatment, is not standard for NS RARP planning.
  • Further research is needed to confirm if CTPA improves functional outcomes and recovery post-RARP.
  • Cost, time, and radiation exposure are factors to consider before routine adoption of CTPA for RARP.
