Mid-term efficacy of non-contact orthopedic robot navigation in the treatment of lumbar spondylolisthesis.

Objective: This study was aimed to explore the mid-term efficacy of non-contact orthopedic robot navigation in the treatment of lumbar spondylolisthesis.

Methods: The clinical data of young and middle-aged patients with lumbar spondylolisthesis were retrospectively analyzed and divided into an observation group and a control group according to surgical methods. The observation group was treated with minimally invasive transforaminal interbody fusion (MIS-TLIF) combined with orthopedic robot-navigated percutaneous pedicle screw fixation; while the control group underwent traditional posterior lumbar interbody fusion (PLIF).

Lipopolysaccharide-enhanced early proliferation of insulin secreting NIT-1 cell is associated with nuclear factor-kappaB- mediated inhibition of caspase 3 cleavage.

Background: Increased levels of plasma lipopolysaccharide (LPS) have been found in obesity and diabetes patients. This study was to investigate the effect of LPS on pancreatic beta-cell viability and the involvement of caspase 3 in NIT-1 cell line.

Methods: Mouse insulinoma NIT-1 cells were treated with LPS for the indicated time and dose.

[Cloning of a large plasmid pBMB28 in Bacillus thuringiensis].

Bacillus thuringiensis serovar. finitimus strain YBT-020 is a typical strain with the spore-crystal association (SCA) phenotype. In our previous studies, plasmid curing experiment suggested that native plasmid pBMB28 of strain YBT-020 might contribute to the SCA phenotype.
