NIH Study Demonstrates Asthma Reduction with Ultraviolet Air Disinfection

Can light turn off the allergens that make you sick? A study of asthmatic children reveals that an ultraviolet air disinfection system in home ventilation ducts can dramatically reduce asthma attacks and allergic reactions to indoor pollutants. The first study of its kind, published in the May issue of the Journal of Asthma, found that participants significantly improved their breathing capacity, reduced medication use two-fold, increased the number of days without symptoms four-fold, and experienced reduced symptom severity when an asthma attack did occur. Ten million people in the U.S. suffer from allergic asthma, and poor indoor air quality contributes to the problem. The study, funded by an NIH Small Business Innovative Research grant, offers hope for an inexpensive and safe way to control allergic asthma.

A/E Confidential: Protecting Trade Secrets

It seems as though everywhere you turn, you run into someone requesting a “confidentiality agreement.” A recent experience comes to mind. I represented a landlord whose prospective tenant was in the commercial real estate brokerage business. The tenant demanded a general confidentiality agreement, presumably to prevent the landlord from snooping around its offices and learning its business secrets. The tenant was eventually persuaded that it was neither appropriate nor necessary; and, indeed, I believe any tenant ought to reconsider leasing if it truly worries about a landlord grabbing its perceived business secrets. For purposes of the current discussion, this story illustrates two things: • The increasing awareness of the value of proprietary business information and intellectual property. • A general lack of understanding among lay business people of what can and should be protected under the law and the mechanics of obtaining such protection. In approaching the topic of confidentiality, one must consider two often-intertwined concepts: confidentiality agreements and trade secrets.
