Filtration00:53

Filtration

715
Filtration is a physical separation process that involves passing a suspension through a porous medium to separate solids from fluids. During filtration, solids collect on the porous medium while liquids, also collectively known as the filtrate, pass through. The filtration medium is selected based on the filtration purpose, quantity, and nature of the precipitate. The general criteria for a suitable filtering medium are that it is inert, mechanically strong, nonabsorbent toward dissolved...

Formation of Intermediate Filaments00:57

Formation of Intermediate Filaments

2.8K
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...

Couette Flow01:22

Couette Flow

110
Couette flow represents the flow of fluid between two parallel plates, with one plate fixed and the other moving with a constant velocity. This configuration allows for a simplified analysis using the Navier-Stokes equations, which govern fluid motion under conditions of viscosity and incompressibility. For Couette flow, the assumptions include a steady, laminar, incompressible flow with a zero-pressure gradient in the flow direction. This flow type is beneficial for understanding shear-driven...

Mechanism of Filopodia Formation01:39

Mechanism of Filopodia Formation

2.2K
Filopodia are thin, actin-rich cellular protrusions that play an important role in many fundamental cellular functions. They vary in their occurrence, length, and positioning in different cell types, suggesting their diverse roles.
Their main function is to guide migrating cells during normal tissue morphogenesis or cancer metastasis by recognizing and making initial contacts with the extracellular matrix. However, they can also act as stationary cell anchors or help to establish communication...

Generation of Straight or Branched Actin Filaments01:14

Generation of Straight or Branched Actin Filaments

2.8K
The straight or branched structure formation of actin filaments is controlled by nucleating proteins such as the formins and Arp2/3 complex. Formin-mediated assembly results in straight filaments, whereas Arp2/3 protein complex-mediated assembly results in branched actin filaments.
Arp2/3 Complex
Arp2/3 complex is a seven-subunit complex consisting of two proteins similar to actin- Arp2 and Arp3, and five other subunits that help keep Arp2 and Arp3 inactive. When required, the complex is...

Types of Intermediate Filaments01:31

Types of Intermediate Filaments

3.5K
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...

Area of Science:

  • Dermatology
  • Wound Healing
  • Pharmacology

Background:

  • Epidermolysis bullosa (EB) is a rare genetic disorder characterized by fragile skin prone to blistering and wounds.
  • Current treatments for EB focus on supportive care and wound management.
  • Filsuvez (birch triterpenes) topical gel offers a novel therapeutic approach for EB wound healing.

Purpose of the Study:

  • To evaluate the efficacy and safety of Filsuvez (birch triterpenes) topical gel in treating epidermolysis bullosa (EB) wounds.
  • To compare the wound healing rates of birch triterpenes topical gel versus a vehicle gel in EB patients.

Main Methods:

  • A randomized, double-blind, controlled, parallel-group, phase III trial (EASE, NCT03068780) involving 223 patients.
  • Patients received either birch triterpenes topical gel or vehicle gel applied as a 1-mm layer to wounds every 4 days for 90 days.
  • The primary endpoint was the first complete closure of the target EB wound by day 45.

Main Results:

  • Complete wound closure by day 45 was achieved in 41.3% of patients treated with birch triterpenes topical gel, versus 28.9% in the vehicle gel group.
  • Application site reactions were infrequent and comparable between the study gel (7.3%) and vehicle gel (6.1%) groups.
  • Birch triterpenes topical gel demonstrated a statistically significant improvement in wound healing.

Conclusions:

  • Filsuvez (birch triterpenes) topical gel is an effective treatment for promoting wound healing in patients with epidermolysis bullosa.
  • The study supports the use of birch triterpenes topical gel as a therapeutic option for EB management.
  • The recommended application is a 1-mm layer to the affected wound surface only.
