2012
A technique called Comprehensive Microarray Polymer Profiling (CoMPP) for the characterisation of plant cell wall glycans is described. This method combines the specificity of monoclonal antibodies directed to defined glycan-epitopes with a miniature microarray analytical platform allowing screening of glycan occurrence in a broad range of biological contexts.

Overview of DNA Repair

In order to be passed through generations, genomic DNA must be undamaged and error-free. However, every day, DNA in a cell undergoes several thousand to a million damaging events by natural causes and external factors. Ionizing radiation such as UV rays, free radicals produced during cellular respiration, and hydrolytic damage from metabolic reactions can alter the structure of DNA. Damages caused include single-base alteration, base dimerization, chain breaks, and cross-linkage. Chemically...

Base Excision Repair

2020
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...

This manuscript describes methods associated with creation and repair of a ventral abdominal wall defect (hernia). This model can be used to study repair strategies such as those that use implanted materials. In this manuscript, repair of the experimental hernia with porcine small intestinal submucosa is presented as an example.

Long-patch Base Excision Repair

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: Lesion type: Depending on the type of base damage, a specific DNA glycosylase - mono or bifunctional, is recruited to the damaged site. While the sequential action of a monofunctional glycosylase favors long patch repair...
FAQs
A tension-free closure reduces stress on the disrupted wall while it heals. In Duodenal Wall Repair, this principle matters because restoring luminal continuity is not sufficient if the closure cannot remain secure. Maintaining a stable repair supports tissue healing and helps limit recurrent leakage of intestinal contents into surrounding areas.
Tissue viability and contamination help determine whether the damaged area can support a secure closure and how challenging the repair may be. Viable tissue provides a more favorable basis for healing, whereas contamination signals a greater risk associated with leakage. These findings guide the repair strategy and influence expected recovery.
Reinforcement is considered when the initial closure may need additional support during healing. Its purpose is to strengthen the repaired area while preserving luminal continuity and reducing the chance that intestinal contents will escape through the disrupted wall. Whether reinforcement is needed depends on the defect, tissue condition, contamination, and surrounding structures.
Several types of damage can create the clinical need for repair, including perforation, trauma, ulceration, and operative injury. The intervention may therefore arise in acute abdominal emergencies or as management of a selected postoperative complication. Identifying the underlying cause helps place the repair within the broader clinical context and guides assessment.
The duodenum lies within an operative environment where nearby structures can affect how a defect is approached and closed. Assessing those structures helps clinicians choose a repair that is appropriate for the local anatomy and tissue condition. This planning supports a secure closure, preserves luminal continuity, and helps reduce complications related to leakage.
The principal goals are preservation of luminal continuity and prevention of intestinal contents from leaking through the repaired wall. Avoiding leakage is important because it can contribute to serious infection. Recovery is also influenced by tissue viability, the degree of contamination, and the condition of surrounding structures at the time of repair.
