Base Excision Repair

One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.
The first step of...

Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...

Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:

In 1882, Flemming observed lampbrush chromosomes (LBC) in salamander eggs. Later in 1892, Rückert observed LBCs in shark egg cells and coined the term "lampbrush chromosomes" because they looked like brushes used to clean kerosene lamps.
LBCs are made up of two pairs of conjugating homologous chromatids. Each chromatid consists of alternatively positioned regions of condensed-inactive chromatin and loosely placed-active side loops, which can be contracted and extended. The loops...

Area of Science:

  • Biodiversity Informatics
  • Digital Asset Management

Background:

  • Institutions and individuals utilize embedded metadata for managing image collections.
  • Existing tools like Adobe Bridge and Flickr leverage embedded metadata for image description, categorization, and licensing.
  • Scratchpads, a biodiversity VRE, previously lacked integrated embedded metadata support, necessitating manual data re-entry.

Purpose of the Study:

  • To develop a module for Scratchpads that integrates embedded image metadata into the platform.
  • To automate the process of extracting and mapping image metadata within Scratchpads.
  • To enhance the efficiency of image management for biodiversity researchers using Scratchpads.

Main Methods:

  • A Drupal module was developed to facilitate metadata mapping.
  • The module allows users to define custom mappings between embedded image metadata fields and Scratchpads image form fields.
  • Integration with the Scratchpads bulk image uploader was ensured for seamless workflow.

Main Results:

  • The module successfully enables automatic extraction of embedded metadata (EXIF, XMP, IPTC) from images.
  • Metadata is automatically mapped to corresponding fields in the Scratchpads image form.
  • Users can now upload hundreds of images with associated metadata efficiently, without manual re-entry.

Conclusions:

  • The developed Drupal module significantly improves image management within the Scratchpads VRE.
  • Automated metadata extraction and mapping reduce manual workload and enhance data consistency.
  • This advancement facilitates better organization and discoverability of biodiversity image collections.
