In a cohort study comparing laminectomy alone to laminectomy with non-instrumented or instrumented fusion, Katz et al. (1997) could not demonstrate any beneficial effect of instrumentation (relative to non-instrumented fusion) in patients older than 50yearss.
The real pain, Pivovaroff says, is being felt mostly by the relative few who build instrumentation.
The relative cost and requirement of specialized instrumentation also is another drawback compared with other techniques, such as immunochemical assays, which use cheaper, portable, and easy-to-use instrumentations [114].
Because of the relative ease and low-cost for instrumentation, the suggested approach has a great potential to be a routine application for element testing.
The relative cost and requirement of specialized instrumentation also is another drawback compared with other techniques, such as immunochemical assays, which use cheaper, portable, and easy-to-use instrumentations [ 114].
In addition, while use of a bioreactor did increase yield (quite dramatically in the case of pMBI coexpression with mevalonate supplementation), the downside is the expense of such instrumentation and their complexity relative to shake flask growths.

Additional rooms for patient consultations, diagnostic instrumentation, ambulant patients, and patients' relatives are desirable.
With this instrumentation it was possible to map the relative spatial distribution of the metal contaminants, Ni and Fe, and correlate these distributions to porosity and permeability changes of an E-cat catalyst particle.
We also observed differences in the relative distributions of protonated conformations depending on experimental conditions and instrumentation, which is consistent with previous studies on aniline in the gas phase.
