Electron Transport Chains01:28

Electron Transport Chains

113.1K
The final stage of cellular respiration is oxidative phosphorylation that consists of two steps: the electron transport chain and chemiosmosis. The electron transport chain is a set of proteins found in the inner mitochondrial membrane in eukaryotic cells. Its primary function is to establish a proton gradient that can be used during chemiosmosis to produce ATP and generate electron carriers, such as NAD+ and FAD, that are used in glycolysis and the citric acid cycle.
The ETC is comprised of...

Radical Chain-Growth Polymerization: Chain Branching

2.5K
The skeletal structure of polymers synthesized via radical polymerization is always branched. For example, the polymerization of ethylene by radical polymerization results in a low-density grade of polyethylene with a heavily branched skeletal structure. Here, the radical site abstracts hydrogen from the growing chain, and the radical site shifts from the end (a primary carbon center) to anywhere within the growing chain (a secondary carbon center). Consequently, the part of the chain from the...

The Chain Rule

73
A system of interconnected gears provides a concrete physical interpretation of the Chain Rule in calculus. Consider three gears arranged in sequence, where the rotational speeds of the first, second, and third gears are represented by the variables x, z, and y, respectively. The first gear drives the second, and the second drives the third, so the motion of each gear depends on the one preceding it. This structure naturally leads to a two-stage variable relationship that can be analyzed using...

Reconstruction of Signal using Interpolation

Signal processing techniques are essential for accurately converting continuous signals to digital formats and vice versa. When a continuous signal is sampled with a period T, the resulting sampled signal exhibits replicas of the original spectrum in the frequency domain, spaced at intervals equal to the sampling frequency. To handle this sampled signal, a zero-order hold method can be applied, which creates a piecewise constant signal by retaining each sample's value until the next...

The thermal expansion of a metal rod shows the application of the Chain Rule when one physical quantity depends on another that varies with time. As the rod is heated, its length changes according to linear thermal expansion, while the temperature of the system varies quadratically with time.For linear thermal expansion, the length L of the rod depends on temperature T such that the rate of change of length with respect to temperature is constant:where L0 = 2 m is the initial length of...

The Electron Transport Chain01:30

The Electron Transport Chain

20.3K
The electron transport chain or oxidative phosphorylation is an exothermic process in which free energy released during electron transfer reactions is coupled to ATP synthesis. This process is a significant source of energy in aerobic cells, and therefore inhibitors of the electron transport chain can be detrimental to the cell's metabolic processes.
Inhibitors of the electron transport chain
Rotenone, a widely used pesticide, prevents electron transfer from Fe-S cluster to ubiquinone or Q...

Area of Science:

  • Otolaryngology
  • Surgical Innovation
  • Global Health

Background:

  • Two-stage middle ear surgeries using prostheses are not cost-effective in Ethiopia.
  • Limited resources necessitate alternative surgical approaches for middle ear reconstruction.

Purpose of the Study:

  • To evaluate the efficacy of single-stage autologous ossiculoplasty in improving tympanic membrane closure and hearing outcomes.
  • To assess the feasibility of this technique in a resource-limited healthcare setting.

Main Methods:

  • A retrospective review of 188 patients (197 ears) undergoing single-stage autologous ossiculoplasty for various middle ear conditions.
  • Reconstruction utilized only autologous ossicles, with most cases involving tympanic membrane perforations.

Main Results:

  • Achieved a 95% tympanic membrane perforation closure rate.
  • Demonstrated an average air-bone gap improvement of 21 dB (from 44 dB to 23 dB), with significant gains in columella reconstructions.
  • No cases reported worsening of sensorineural hearing or implant extrusion.

Conclusions:

  • Single-stage autologous ossiculoplasty is a successful and effective surgical option in resource-limited environments.
  • This method provides acceptable tympanic membrane closure and hearing improvement without the need for costly prostheses.
