Mechanical Protein Functions

Mechanical Protein Functions

Proteins perform many mechanical functions in a cell. These proteins can be classified into two general categories- proteins that generate mechanical forces and proteins that are subjected to mechanical forces. Proteins providing mechanical support to the structure of the cell, such as keratin, are subjected to mechanical force, whereas proteins involved in cell movement and transport of molecules across cell membranes, such as an ion pump, are examples of generating mechanical force.

Combined Effects of Drugs: Synergism

Combined Effects of Drugs: Synergism

Synergism is a useful mechanism where combining two or more drugs is more effective than each constituent used alone. Such combinations are also called supra-additive interactions. The drugs collectively enhance the final therapeutic effect by acting on different targets. Another advantage is that the low dose of each constituent drug is sufficient to achieve the desired effect. This helps reduce the duration of therapy and lower the adverse effects of these drugs.
Such synergistic combinations...

Combined Effects of Drugs: Antagonism

Combined Effects of Drugs: Antagonism

The combined effects of drugs can result in various interactions, of which an important type is antagonism. Antagonism is a mechanism where one drug inhibits or counteracts the effects of another drug. Antagonism can occur through various means, including receptor binding, allosteric modulation, functional interaction, chemical reactions, and pharmacokinetic processes.
The most common type is receptor antagonism, where one drug acts as an antagonist to block the effects of another drug by...

Buffer Effectiveness

Buffer Effectiveness

Buffer solutions do not have an unlimited capacity to keep the pH relatively constant . Instead, the ability of a buffer solution to resist changes in pH relies on the presence of appreciable amounts of its conjugate weak acid-base pair. When enough strong acid or base is added to substantially lower the concentration of either member of the buffer pair, the buffering action within the solution is compromised.
The buffer capacity is the amount of acid or base that can be added to a given volume...

Reaction Mechanisms

Reaction Mechanisms

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.
For instance, the decomposition of ozone appears to follow a mechanism with two steps:

Background:

The Internet of Things (IoT) enables interconnected smart applications but faces significant cybersecurity challenges due to resource-constrained devices.
Existing complex cryptographic methods are unsuitable for IoT, and current systems suffer from vulnerabilities in device and user identification.
Securing user and device identity is a critical challenge in IoT cybersecurity.

Purpose of the Study:

To propose an effective multifactor authentication (CMA) solution for IoT devices.
To address authentication vulnerabilities and defend against various cyberattacks in IoT systems.
To ensure the integrity, authenticity, and availability of sensed data for legitimate IoT devices.

Main Methods:

Developed a multifactor authentication solution (CMA) using robust combiners of hash functions implemented on IoT devices.
Evaluated the proposed CMA solution's performance against Time-based One-Time Password (TOTP) in terms of authentication failure rate.
Assessed Quality of Service (QoS) metrics including computation time overhead, throughput, and packet loss ratio.

Main Results:

The proposed CMA solution effectively mitigates IoT authentication vulnerabilities and defends against multiple attack types.
CMA demonstrates multi-property robustness, preserving essential cryptographic characteristics like collision-resistance and one-wayness.
Simulation results indicate CMA outperforms TOTP in reducing the authentication failure rate.

Conclusions:

The CMA solution provides a secure and robust multifactor authentication mechanism for resource-constrained IoT environments.
The proposed method ensures data integrity, authenticity, and availability while maintaining acceptable QoS.
CMA offers a viable approach to enhance IoT cybersecurity and overcome limitations of traditional authentication methods.
