Effect of Linker Length on the Function of Biotinylated OSW-1 Probes.

The biotinylated probes based on anticancer saponin OSW-1 with varied linker lengths were synthesized and their cell growth inhibitory activity and affinity pulldown efficiency were evaluated. All probes demonstrated comparable cytotoxicity to the parent natural product, highlighting that the linker moiety had a minimal impact on cell uptake or target engagement. In contrast, when evaluated against the known target proteins, OSBP and ORP4, the biotinylated probe 3 with PEG5 linker enabled most effective enrichment of target proteins in the affinity pulldown assay, suggesting that the cytotoxicity and pulldown efficiency did not correlate among the probes studied.

Minimally Invasive Spinal Treatment (MIST)-A New Concept in the Treatment of Spinal Diseases: A Narrative Review.

In the past two decades, minimally invasive spine surgery (MISS) techniques have been developed for spinal surgery. Historically, minimizing invasiveness in decompression surgery was initially reported as a MISS technique. In recent years, MISS techniques have also been applied for spinal stabilization techniques, which were defined as minimally invasive spine stabilization (MISt), including percutaneous pedicle screws (PPS) fixation, lateral lumbar interbody fusion, balloon kyphoplasty, percutaneous vertebroplasty, cortical bone trajectory, and cervical total disc replacement.

The History and Development of the Percutaneous Pedicle Screw (PPS) System.

Minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) using the SEXTANT system (Medtronic) featured the first generation of commercially available percutaneous pedicle screw (PPS) system in 2001. The innovative system has since become standard instrumentation used worldwide, and PPS is now used for long-segment minimally invasive surgery (MIS) spinal fixation from the thoracic spine to the pelvis for pathological conditions. PPS systems have been developed for approximately 20 years for the purpose of improving minimally invasive techniques, safety of instrumentation, and ease of use.
