Fixing Double-strand Breaks

14.7K
The double-stranded structure of DNA has two major advantages. First, it serves as a safe repository of genetic information where one strand serves as the back-up in case the other strand is damaged. Second, the double-helical structure can be wrapped around proteins called histones to form nucleosomes, which can then be tightly wound to form chromosomes. This way, DNA chains up to 2 inches long can be contained within microscopic structures in a cell. A double-stranded break not only damages...

The Intermediate Value Theorem01:25

The Intermediate Value Theorem

277
The Intermediate Value Theorem is a foundational result in calculus that guarantees the existence of solutions within certain intervals for continuous functions. Formally, the Intermediate Value Theorem states that if a function f is continuous on the closed interval [a, b], and if N is any value between f(a) and f(b), then there exists at least one c ∈ (a, b) such that f(c) = N. This theorem is instrumental in proving the existence of roots and in analyzing the behavior of continuous...

Disassembly of Intermediate Filaments01:35

Disassembly of Intermediate Filaments

2.7K
Intermediate filaments (IFs) do not undergo spontaneous disassembly. Enzymes, kinases, and phosphatases add and remove phosphates from specific sites to regulate their disassembly. The IF concentration in the cytoplasm also regulates the disassembly. If the concentration crosses a threshold, it activates the protein kinases in the vicinity, allowing the phosphorylation of IFs.
Keratin proteins, found at the cell periphery near cell junctions, undergo a cycle of assembly and disassembly. In Type...

Types of Intermediate Filaments01:31

Types of Intermediate Filaments

4.9K
The intermediate filaments are an essential component of the cytoskeleton. Presently six types of intermediate filament have been identified. Type I and II are acidic and basic keratin proteins. Type III is of mesodermal origin and comprises four proteins: vimentin, desmin, glial fibrillary acidic protein (GFAP), and peripherin. Vimentin is commonly found in mesenchymal cells, desmin in muscle cells, GFAP in astrocytes, while peripherin is found in peripheral nervous system neurons (PNS). Type...

Formation of Intermediate Filaments00:57

Formation of Intermediate Filaments

4.0K
Intermediate filaments are cytoskeletal proteins with higher tensile strength and flexibility than microfilaments and microtubules. Unlike the other two cytoskeletal proteins, intermediate filament formation lacks the enzymatic activity to hydrolyze nucleotides like ATP and GTP to generate energy for polymerization. Therefore, the formation of intermediate filaments is multistep self-assembly. The involvement of any accessory proteins in intermediate filament formation has not yet been...

Summary

This study shows that localized vitrectomy is a safe and effective treatment for rhegmatogenous retinal detachment (RRD) in phakic eyes. The procedure achieved a 94% success rate for retinal reattachment without causing cataract progression.

Area of Science:

  • Ophthalmology
  • Retinal Surgery
  • Vitreoretinal Interface

Background:

  • Rhegmatogenous retinal detachment (RRD) with significant vitreous traction presents surgical challenges.
  • Traditional vitrectomy techniques may carry risks of cataract progression in phakic eyes.

Purpose of the Study:

  • To evaluate a modified "localized 25-gauge vitrectomy" technique.
  • To assess its efficacy in treating uncomplicated macula-on RRD with vitreous traction in phakic eyes.

Main Methods:

  • Prospective, interventional case series of 32 phakic eyes with RRD.
  • Localized 25-gauge vitrectomy with air infusion, laser, and air tamponade was performed.
  • Primary outcome: primary retinal reattachment rate; Secondary outcomes: cataract progression and complications.

Main Results:

  • High anatomical success rate of 94% at 12 months.
  • No significant change in nuclear density units, indicating no cataract progression.
  • Low complication rate: one epiretinal membrane and one cystoid macular edema.

Conclusions:

  • Localized vitrectomy is highly effective for RRD in phakic eyes with vitreous traction.
  • This technique offers a high success rate for retinal reattachment.
  • The procedure does not appear to accelerate cataract formation.
