Histone Modification

2020
The histone proteins have a flexible N-terminal tail extending out from the nucleosome. These histone tails are often subjected to post-translational modifications such as acetylation, methylation, phosphorylation, and ubiquitination. Particular combinations of these modifications form “histone codes” that influence the chromatin folding and tissue-specific gene expression. Acetylation The enzyme histone acetyltransferase adds acetyl group to the histones. Another enzyme, histone deacetylase,...

The histone proteins in the nucleosomes are post-translationally modified (PTM) to increase or decrease access to DNA. The commonly observed PTMs are methylation, acetylation, phosphorylation, and ubiquitination of lysine amino acids in the histone H3 tail region. These histone modifications have specific meaning for the cell. Hence, they are called "histone code". The protein complex involved in histone modification is termed as "reader-writer" complex. Writers The writer is an enzyme that can...

A reliable and useful approach to detect histone modifications on specific plant genes is described. The approach combines chromatin immunoprecipitation (ChIP) and real-time quantitative PCR. It allows detection of histone modifications on specific genes with a role in diverse physiological processes.

Robert M Rioux, Ajay Sathe, Zhifeng Chen, Pennsylvania State University, University Park, PA A glovebox is an isolated enclosure that is designed to maintain an inert atmosphere. The manipulation of chemicals or apparatus is done via the use of gloves, which allow operation while still maintaining an inert atmosphere. A positive pressure is utilized to compensate for any passive leaks. Objects can be transferred in and out of the box using an antechamber that acts as an airlock between the box...

Source: Kerry M. Dooley and Michael G. Benton, Department of Chemical Engineering, Louisiana State University, Baton Rouge, LA Processing of biochemicals involves unit operations such as crystallization, ultracentrifugation, membrane filtration, and preparative chromatography, all of which have in common the need to separate large from small molecules, or solid from liquid. Of these, crystallization is the most important from a tonnage standpoint. For that reason, it is commonly employed in the...
FAQs
Separating sterile and nonsterile zones controls movement within the room and limits unnecessary crossings around the operative field. This arrangement supports infection prevention by maintaining controlled traffic patterns and environmental conditions. It also gives the surgical team more predictable access to the patient and working areas throughout a procedure.
The positions of the surgical table and equipment influence how easily the surgical team can reach the patient and perform procedural tasks. A carefully arranged layout can reduce obstacles, improve workflow, and support ergonomics. These considerations become especially important when a procedure requires several devices or coordinated activity around the operating table.
These systems adapt the room to clinical and procedural requirements. Lighting supports the surgical work area, while ventilation contributes to controlled environmental conditions. Integrated imaging and monitoring equipment can accommodate procedures that depend on specialized technology. Their placement and integration must preserve patient access, team access, and an effective workflow.
Planning begins by identifying the clinical, safety, and procedural requirements that the room must meet. Designers then determine whether changes to the table position, equipment locations, sterile zones, lighting, ventilation, imaging, monitoring, or workflow are needed. The proposed arrangement should be considered as a complete system so that one change does not obstruct access or controlled movement.
A facility may consider this approach when it needs to accommodate a new procedure, integrate advances in surgical technology, or adapt care spaces to changing patient-care requirements. Modification can also address workflow, access, infection-prevention, or ergonomic needs. The specific changes depend on the clinical activities and equipment the room must support.
A well-designed room can improve access to the patient, support more efficient workflow, and provide better ergonomic conditions for the surgical team. Maintaining appropriate sterile and nonsterile zones and controlled environmental conditions also supports infection prevention. Together, these outcomes help the facility respond to evolving procedures and technology while sustaining organized patient care.
