Cellular Membranes and Drug Transport01:24

Cellular Membranes and Drug Transport

1.1K
Drugs must traverse multiple biological barriers, such as multi-layered skin, single-layered intestinal epithelium, and the plasma membrane, to reach their target sites within the body. The plasma membrane, a highly structured composite of phospholipids, carbohydrates, and proteins, is the cell's protective boundary, facilitating selective substance exchange.
Phospholipids arrange themselves into a bilayer, with hydrophilic heads oriented outward and hydrophobic tails facing inward.

Protein Diffusion in the Membrane01:24

Protein Diffusion in the Membrane

5.1K
Proteins show rotational as well as lateral diffusion across the membrane. The lateral diffusion of proteins was confirmed through the cell fusion experiment where mouse and human cells were fused, resulting in hybrid cells. When the human and mouse cells fused, the specific membrane proteins on human and mouse cells were marked with the red and green-fluorescent markers, respectively. Initially, the red and green fluorescence was located on the respective hemisphere of the cell. As time...

Chemotaxis and Direction of Cell Migration01:21

Chemotaxis and Direction of Cell Migration

4.0K
Cells can detect chemical cues in their environment and reorganize the cytoskeleton to migrate toward them or away from them. This directional migration, called chemotaxis, is essential during embryogenesis and development, immune response, tissue repair and regeneration, and reproduction. These chemical cues can either attract or repel the cell's movement. For example, axon development is determined by a combination of chemoattractants and chemorepellents that direct the growing axon...

Cytoskeletal Coordination in Cell Migration01:32

Cytoskeletal Coordination in Cell Migration

5.1K
A migrating cell changes its shape during the cyclic events of attachment and detachment from the substratum and repositions the cell organelles correspondingly. These complex events are orchestrated by the dynamic cytoskeletal network comprising actin filaments, intermediate filaments, and microtubules. Cytoskeletal crosstalk — the direct and indirect communication between the different components — is crucial for this coordination. Direct communication involves various linker...

Role of Myosin in Cell Migration01:18

Role of Myosin in Cell Migration

2.7K
Myosins are multimeric motor proteins involved in various cellular processes such as migration, adhesion, and proliferation. Myosin II is the most common type in animal cells, which binds and cross-links actin filaments.
Myosin II  is a hexamer comprising two heavy chains with globular heads and coiled-coil tails, two regulatory light chains, and two essential light chains. The ATPase sites on the myosin heads hydrolyze ATP, and the released phosphate generates the force for contraction....

Masking and Demasking Agents01:19

Masking and Demasking Agents

3.1K
EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These agents facilitate the sequential analysis of the metal ions by forming stable complexes with some—but not all—metal ions during certain steps.
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on...

Area of Science:

  • Computer Science
  • Network Security
  • Cybersecurity

Background:

  • Mobile ad-hoc networks (MANETs) lack infrastructure, making them vulnerable to attacks.
  • Existing security mechanisms for wired networks are not directly applicable to MANETs.
  • Enhanced security is crucial for MANETs in military and emergency rescue scenarios.

Purpose of the Study:

  • To propose a low-cost and efficient anti-invasion, anti-eavesdropping, and anti-attack mechanism for MANETs.
  • To enhance MANET security using a moving target defense (MTD) strategy.
  • To develop a two-layer IP hopping-based MTD approach for improved network resilience.

Main Methods:

  • A two-layer IP hopping mechanism is proposed, where device IP addresses dynamically change.
  • The MTD scheme alters system configurations to create inaccessibility for intruders.
  • The approach integrates data encryption for comprehensive security levels.

Main Results:

  • The proposed MTD scheme prevents device IP addresses from being exposed on the wireless physical channel.
  • Two-layer IP hopping with individualized intervals and rules enhances MANET security.
  • The system offers three security levels: anti-intrusion, intrusion detection, and anti-eavesdropping.

Conclusions:

  • The two-layer IP hopping MTD approach provides robust security for MANETs.
  • This method maintains a relatively low computational load and communication cost.
  • The implemented scheme effectively secures MANETs in diverse and hostile environments.
