About Cabling Installation & Maintenance

Our mission: Bringing practical business and technical intelligence to today's structured cabling professionals

For more than 30 years, Cabling Installation & Maintenance has provided useful, practical information to professionals responsible for the specification, design, installation and management of structured cabling systems serving enterprise, data center and other environments. These professionals are challenged to stay informed of constantly evolving standards, system-design and installation approaches, product and system capabilities, technologies, as well as applications that rely on high-performance structured cabling systems. Our editors synthesize these complex issues into multiple information products. This portfolio of information products provides concrete detail that improves the efficiency of day-to-day operations, and equips cabling professionals with the perspective that enables strategic planning for networks’ optimum long-term performance.

Throughout our annual magazine, weekly email newsletters and 24/7/365 website, Cabling Installation & Maintenance digs into the essential topics our audience focuses on.

  • Design, Installation and Testing: We explain the bottom-up design of cabling systems, from case histories of actual projects to solutions for specific problems or aspects of the design process. We also look at specific installations using a case-history approach to highlight challenging problems, solutions and unique features. Additionally, we examine evolving test-and-measurement technologies and techniques designed to address the standards-governed and practical-use performance requirements of cabling systems.
  • Technology: We evaluate product innovations and technology trends as they impact a particular product class through interviews with manufacturers, installers and users, as well as contributed articles from subject-matter experts.
  • Data Center: Cabling Installation & Maintenance takes an in-depth look at design and installation workmanship issues as well as the unique technology being deployed specifically for data centers.
  • Physical Security: Focusing on the areas in which security and IT—and the infrastructure for both—interlock and overlap, we pay specific attention to Internet Protocol’s influence over the development of security applications.
  • Standards: Tracking the activities of North American and international standards-making organizations, we provide updates on specifications that are in-progress, looking forward to how they will affect cabling-system design and installation. We also produce articles explaining the practical aspects of designing and installing cabling systems in accordance with the specifications of established standards.

Polymer protection for vaccines and drugs



TSUKUBA, Japan, Dec 9, 2022 - (ACN Newswire) - A biocompatible polymer could help deliver vaccines and drugs with reduced risk of the rare dangerous adverse reaction called anaphylaxis. Researchers at the National Institute of Advanced Industrial Science and Technology (AIST) in Japan have developed the polymer and performed preliminary tests, which they report in the journal Science and Technology of Advanced Materials.

A liposome (left) containing a vaccine is commonly coated with polyethylene glycol (PEG) but it can trigger an allergic reaction to some recipients. A newly developed lipid (right) could serve as a safer, alternative liposome-coating while retaining the vaccine longer in the body.


Until now, the polymer of choice for encasing and delivering vaccines has been poly(ethylene glycol) (PEG). This synthetic, flexible, water-soluble material has been used to surround some COVID-19 vaccines carried within the tiny spherical packages known as liposomes.

Unfortunately, some recipients have suffered an anaphylactic reaction to PEG, in which the immune system mounts an allergic response to the foreign material. Symptoms of anaphylaxis range from minor skin irritations, to breathing difficulty, nausea and, in the worst cases, unconsciousness and sudden death.

The alternative polymer is a form of fatty biomolecule called a lipid, and is conjugated to 2-methacryloyloxyethyl phosphorylcholine (MPC) polymer.

This new substance spontaneously binds to the outside of liposome particles when mixed with them in water. Crucially, the polymer is not recognized by the antibodies that the body can generate in response to PEG, and tests suggest it does not stimulate any other antibodies that could cause an allergic reaction. This should allow coated liposomes containing a vaccine to be retained in the body for a longer time without being cleared by the immune system, in addition to avoiding anaphylaxis.

"We have also found that the polymer avoids other interactions with proteins in the blood that might otherwise interfere with its effects, and it also prevents liposomes from aggregating together," says molecular engineer Yuji Teramura of the AIST team.

Tests confirm the coated liposomes can remain stable in storage for 14 days, sufficient for real clinical applications.

"All the indications suggest that our technology should be suitable for delivering vaccines into patients who develop anaphylaxis in response to PEG," Teramura concludes.

The polymer must now be thoroughly tested in various real vaccine applications. The team is moving into this next crucial phase of the development process, prior to eventual clinical trials in humans.

Provided the animal and subsequent clinical trials go well, the technology should offer opportunities for delivering drugs into the body, in addition to vaccines. Delivery systems such as liposomes are sometimes needed to protect drugs from biochemical processes that might degrade them. This can ensure that they reach the target disease tissues while remaining in their active form.
