Poly(ADP-ribose) synthetase (PARS) activation: a pathway of cellular oxidant injury PARS is a protein-modifying and nucleotidepolymerizing enzyme that is abundantly present in the nucleus [l]. Its activation results in the cleavage of NAD' into ADP-ribose and nicotinamide. In turn, PARS covalently attaches ADPribose to various proteins, including nuclear proteins, histones and an automodificati...

Uptake of L-proline, hydroxy-L-proline and 5-oxo-L-proline by luminal-membrane vesicles isolated either from whole cortex or from pars convoluta or pars recta of proximal tubules was studied by a spectrophotometric method. Uptake of L-proline and hydroxy-L-proline by vesicles from whole cortex was mediated by both Na+dependent and Na+-independent, but electrogenic, processes, whereas transport ...

PURPOSE To assess the trends in pars plana vitrectomy surgery rates and factors affecting rate change between 2002 and 2013 in South Korea. METHODS Data from National Health Insurance Service-National Sample Cohort 2002-2013, which represents 1,025,340 samples with a sampling rate of 2.2% from the total eligible Korean population, was analyzed. RESULTS A total of 3,816 vitrectomy procedures...

Pars plana vitrectomy for acute infectious endophthalmitis can be challenging due to severe inflammation in the anterior chamber creating significant media opacity. We describe a surgical technique combining limbal based vitrectomy and pars plana vitrectomy to manage acute infectious endophthalmitis. Limbal based vitrectomy facilitates removal of anterior chamber fibrin and inflammatory membran...

OBJECTIVE The optimal treatment modality for traumatic spondylolisthesis of the axis is still a controversial issue. Many conservative, posterior and anterior fixation techniques have been used to treat these injuries. The C2 pars (isthmus) was used as a novel screw anchor point in upper cervical spine injuries. The direct C2 pars screws are also used to fixate the posterior and anterior parts ...

Organization and segregation of replicated chromosomes are essential processes during cell division in all organisms. Similar to eukaryotes, bacteria possess centromere-like DNA sequences (parS) that cluster at the origin of replication and the structural maintenance of chromosomes (SMC) complexes for faithful chromosome segregation. In Bacillus subtilis, parS sites are bound by the partitionin...

We report a case with compression myelopathy due to proliferative changes around the C2 pars defects without instability. A 69-year-old man presented with progressive clumsy hands and spastic gait. Plain radiographs showed bilateral spondylolysis (pars defects) at C2 and fusion between C2 and C3 spinous processes. Dynamic views revealed mobility through the pars defects, but there was no appare...
