Coupled Reactions01:17

Coupled Reactions

7.7K
Cellular processes such as building and breaking down complex molecules occur through stepwise chemical reactions. Some of these chemical reactions are spontaneous and release energy, whereas others require energy to proceed. Cells often couple the energy-releasing reaction with the energy-requiring one to carry out important cell functions. 
Energy in adenosine triphosphate or ATP molecules is easily accessible to do work. ATP powers the majority of energy-requiring cellular reactions....

Conservative Site-specific Recombination and Phase Variation02:53

Conservative Site-specific Recombination and Phase Variation

6.0K
Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.
The recognition sites for Cre recombinase called LoxP...

Exon Recombination02:32

Exon Recombination

3.6K
The evolution of new genes is critical for speciation. Exon recombination, also known as exon shuffling or domain shuffling, is an important means of new gene formation. It is observed across vertebrates, invertebrates, and in some plants such as potatoes and sunflowers. During exon recombination, exons from the same or different genes recombine and produce new exon-intron combinations, which might evolve into new genes. 
Exon shuffling follows “splice frame rules.” Each exon...

Stability of Substituted Cyclohexanes02:30

Stability of Substituted Cyclohexanes

12.6K
This lesson discusses the stability of substituted cyclohexanes with a focus on energies of various conformers and the effect of 1,3-diaxial interactions.
The two chair conformations of cyclohexanes undergo rapid interconversion at room temperature. Both forms have identical energies and stabilities, each comprising equal amounts of the equilibrium mixture. Replacing a hydrogen atom with a functional group makes the two conformations energetically non-equivalent.
For example, in...

Woodward–Hoffmann Selection Rules and Microscopic Reversibility01:34

Woodward–Hoffmann Selection Rules and Microscopic Reversibility

3.1K
Electrocyclic reactions, cycloadditions, and sigmatropic rearrangements are concerted pericyclic reactions that proceed via a cyclic transition state. These reactions are stereospecific and regioselective. The stereochemistry of the products depends on the symmetry characteristics of the interacting orbitals and the reaction conditions. Accordingly, pericyclic reactions are classified as either symmetry-allowed or symmetry-forbidden. Woodward and Hoffmann presented the selection criteria for...

Phase I Reactions: Reductive Reactions01:27

Phase I Reactions: Reductive Reactions

202
Phase I biotransformation reductive reactions are chemical processes that modify drugs by introducing or revealing polar functional groups via reduction. Enzymes called reductases catalyze these reactions, playing a pivotal role in drug metabolism by transforming lipophilic drugs into more polar, water-soluble metabolites for easy excretion. An essential type of reductive reaction is the carbonyl group reduction, where aldehydes and ketones are reduced to alcohols. An example is the...

Area of Science:

  • Demographic History
  • Historical Epidemiology
  • Social History

Background:

  • The seminal work 'English Population History from Family Reconstitution 1580-1837' utilized family reconstitution from 26 English parishes.
  • This dataset offers enduring value for contemporary research into intergenerational patterns of fertility and mortality.
  • Challenges in historical demographic research include data quality and methodological consistency.

Purpose of the Study:

  • To present the translation of historical family reconstitution data into modern digital formats.
  • To evaluate the influence of methodological decisions on the analysis of historical demographic data.
  • To assess the impact of parish register quality and adherence to family reconstitution principles on fertility measurements.

Main Methods:

  • Family reconstitution methodology, as developed by Louis Henry, was applied to 26 selected English parishes.
  • Data were transformed into a relational database and an Intermediate Data Structure (IDS).
  • An episode file was created specifically for fertility analysis.

Main Results:

  • The conversion process created accessible digital formats (IDS, episode file) for the family reconstitution data.
  • Methodological choices, including handling register quality, demonstrably affect fertility measurements.
  • Ignoring key principles of family reconstitution can introduce significant analytical biases.

Conclusions:

  • The digitized family reconstitution data enhance accessibility for new research on historical English population dynamics.
  • Careful consideration of methodological choices is crucial for accurate analysis of historical fertility and mortality.
  • The study underscores the importance of rigorous application of established demographic principles for reliable historical research.
