Global Regulatory Systems

845
Global regulatory systems in bacteria enable rapid and coordinated responses to environmental changes by integrating sensory inputs with gene expression, ensuring efficient adaptation to fluctuating conditions. Key global regulatory mechanisms include regulons, two-component systems, sigma factors, and secondary messengers.Regulons and Global RegulatorsA regulon is a collection of genes and operons controlled by a common global regulator. These regulators enable bacteria to prioritize resource...

Drug Control Governance: Regulatory Bodies and Their Impact

639
Drug control governance involves the oversight and regulation of pharmaceuticals to ensure their safety and efficacy while preventing illegal drug use and trafficking. Regulatory bodies, including the US Food and Drug Administration (FDA) and the European Union's European Medicines Agency (EMA), play a central role in this process. These agencies evaluate the safety and efficacy of drugs before they can be marketed. They fund clinical trials and assess the benefits and risks associated with...

Gene Regulation in Microbial Communities: Quorum Sensing

849
Quorum sensing is a mechanism of bacterial communication that enables coordinated gene expression in response to changes in population density. This facilitates collective behaviors that enhance survival, resource acquisition, and ecological adaptation. This process relies on small signaling molecules called autoinducers that accumulate as bacterial populations grow. When a critical threshold concentration of autoinducers is reached, bacterial cells collectively modify gene expression,...

Drug Regulation

3.3K
Drug regulation encompasses the management of drug usage by evaluating its safety and efficacy through assessments conducted by regulatory authorities. Regrettably, the history of drug regulation is marred by several catastrophic events. One such incident is the Elixir Sulfanilamide tragedy, in which the toxic compound diethyl glycol was included in a sweet-tasting medication, leading to numerous fatalities. This event prompted the enactment of the Food, Drug, and Cosmetic Act in 1938. Under...

Cis-regulatory Sequences02:02

Cis-regulatory Sequences

12.1K
Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...

Area of Science:

  • Clinical Laboratory Science
  • Medical Diagnostics
  • Quality Management Systems

Background:

  • Internal quality control (IQC) is vital for medical laboratory result accuracy and risk management.
  • The International Organization for Standardization (ISO) 15189:2012 standard increased demands on IQC, highlighting a need for standardized approaches.
  • Current IQC practices in diagnostic laboratories are inconsistent, indicating a need for international guidance.

Purpose of the Study:

  • To address the inconsistency and diversity in diagnostic laboratory IQC approaches.
  • To propose a standardized, user-friendly template for designing and implementing IQC programs.
  • To provide recommendations for IQC that align with ISO 15189:2012 requirements.

Main Methods:

  • Critical examination of the essential elements across four stages of an IQC program: staff education, IQC material, IQC targets, and IQC procedure.
  • Stratification of a proposed methodology into these four practical stages.
  • Development of recommendations based on published literature and collective experience in clinical biochemistry and diagnostic endocrinology.

Main Results:

  • A proposed IQC program template designed for ease of use, flexibility, and harmonization of practice.
  • Recommendations for IQC implementation and monitoring that meet ISO 15189:2012 standards.
  • Identification of IQC as a continuous process driven by risk analysis, economic factors, and professional leadership.

Conclusions:

  • The proposed IQC template offers a pragmatic approach to harmonize laboratory practices nationally.
  • There is a critical need for international consensus and regulation on minimum criteria for IQC implementation, monitoring, and review.
  • Effective IQC is central to ensuring the quality and reliability of patient test results.
