Abstract: Racks and cabinets for housing information technology equipment are disclosed. In these racks and cabinets, a number of upright members are connected to cross-members to define a rectilinear frame. Mounting rails are coupled directly or indirectly to the upright members to carry the equipment. Each of the upright members defines an interior compartment along its length with an opening that spans at least a majority of the width of the upright member. In many embodiments, the width of the opening will span 70%, 80%, or more of the width of the upright member. The interior compartments of the upright members are configured as cable raceways and spaces for storing support equipment.

Abstract: The present invention provides a method, referred to as CpG retrieval, to overcome incomplete bisulfite modification of DNA recovered from formalin-fixed tissue samples. The method involves boiling deparaffinized tissue samples in citrate buffer, followed by DNA extraction for promoter methylation analysis. In general, the extracted DNA is further modified by sodium bisulfite and then subjected to a method of promoter methylation analysis. The present invention also reports that hypermethylation of ataxia-telangiectasia-mutated gene promoter is correlated with decreased overall survival in patient with head and neck squamous cell carcinoma.
