Multi-input and Multi-variable systems

403
Cruise control systems in cars are designed as multi-input systems to maintain a driver's desired speed while compensating for external disturbances such as changes in terrain. The block diagram for a cruise control system typically includes two main inputs: the desired speed set by the driver and any external disturbances, such as the incline of the road. By adjusting the engine throttle, the system maintains the vehicle's speed as close to the desired value as possible.
In the absence of...

Multi-Step Reactions02:31

Multi-Step Reactions

8.7K
Chemical reactions often occur in a stepwise fashion involving two or more distinct reactions taking place in a sequence. A balanced equation indicates the reacting species and the product species, but it reveals no details about how the reaction occurs at the molecular level. The reaction mechanism (or reaction path) provides details regarding the precise, step-by-step process by which a reaction occurs. Each of the steps in a reaction mechanism is called an elementary reaction. These...

Multi-species Conserved Sequences

4.6K
Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale  studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved...

Insertion of Multi-pass Transmembrane Proteins in the RER01:29

Insertion of Multi-pass Transmembrane Proteins in the RER

17.9K
The rough ER membrane synthesizes, assembles, and embeds transmembrane proteins in diverse topologies. These proteins function as transporters or channels and can remain in the ER membrane or are sent to the Golgi complex, lysosome, and cell membrane.
The multipass transmembrane proteins are the type IV integral membrane proteins with multiple topogenic sequences determining their spatial arrangement in the ER membrane. Nearly all multipass proteins lack a cleavable signal sequence and use...

Multi-pass Transmembrane Proteins and β-barrels01:09

Multi-pass Transmembrane Proteins and β-barrels

6.4K
In multi-pass transmembrane proteins, the polypeptide chain crosses the membrane more than once. The transmembrane polypeptide chain either forms an α-helix or β-strand structure. α-Helix containing multi-pass transmembrane proteins are ubiquitous, whereas β-strand containing ones are mainly found in gram-negative bacteria, mitochondria, and chloroplasts.

Area of Science:

  • Otolaryngology
  • Surgical Oncology
  • Laryngeal Cancer Treatment

Background:

  • Supratracheal laryngectomy aims to preserve laryngeal function for specific cancers.
  • It is an alternative to supracricoid laryngectomy to avoid compromised margins.

Purpose of the Study:

  • Evaluate the safety, viability, and margin adequacy of supratracheal laryngectomy.
  • Assess outcomes for intermediate and advanced laryngeal cancer across three Brazilian institutions.

Main Methods:

  • Retrospective analysis of 29 patients undergoing supratracheal laryngectomy (1997-2017).
  • Classification according to European Laryngological Society standards.
  • Evaluation of early/late results, survival rates, and follow-up (mean 44 months).

Main Results:

  • Low rate of compromised margins (3.4%) and recurrence (13.8%).
  • 5-year survival rates: Overall (82.1%), Disease-Free (83.0%), Specific (88.2%), Total Laryngectomy-Free (80.2%).
  • 17.2% required total laryngectomy, with 80% success in revision procedures.

Conclusions:

  • Supratracheal laryngectomy is a beneficial option for selected patients with intermediate/advanced laryngeal cancer.
  • Achieves high total laryngectomy-free and specific survival rates.
  • Demonstrates safety and efficacy in preserving laryngeal function while maintaining cancer control.
