Proximal Junction Kyphosis in Adult Scoliosis: Best Postoperative Radiological Predictors—A Retrospective Cohort Study

Advances in Orthopedics, 2022
Background. Proximal junction kyphosis (PJK) is the postsurgical radiographic event seen in the surgical plane after the fusion of a spinal deformity. Unfavorable health outcomes have been reported in symptomatic PJK patients compared to non-PJK patients.

3D Null Point Reconnection Regimes [PDF]

Phys. Plasmas 16, 122101 (2009), 2009
Recent advances in theory and computational experiments have shown the need to refine the previous categorisation of magnetic reconnection at three-dimensional null points -- points at which the magnetic field vanishes. We propose here a division into three different types, depending on the nature of the flow near the spine and fan of the null.

The Impact of the 2006 Massachusetts Healthcare Reform on Spine Surgery Patient Payer-Mix and Age [PDF]

, 2017
OBJECTIVE Several similarities exist between the Massachusetts health care reform law of 2006 and the Affordable Care Act (ACA). The authors’ prior neurosurgical research showed a decrease in uninsured surgeries without a significant change in surgical ...

Spines of minimal length [PDF]

Ann. Sc. Norm. Super. Pisa Cl. Sci. 17:3 (2017), 1067-1090, 2015
In this paper we raise the question whether every closed Riemannian manifold has a spine of minimal area, and we answer it affirmatively in the surface case. On constant curvature surfaces we introduce the spine systole, a continuous real function on moduli space that measures the minimal length of a spine in each surface.

The N-methyl-d-aspartate receptor antagonist CPP alters synapse and spine structure and impairs long-term potentiation and long-term depression induced morphological plasticity in dentate gyrus of the awake rat [PDF]

, 2010
Long-term morphological synaptic changes associated with homosynaptic long-term potentiation (LTP) and heterosynaptic long-term depression (LTD) in vivo, in awake adult rats were analyzed using three-dimensional (3-D) reconstructions of electron ...

The spine which was no spine

, 2007
Let T_n be the Teichmueller space of flat metrics on the n-dimensional torus and identify SL(n,Z) with the corresponding mapping class group. We prove that the subset Y consisting of those points at which the systoles generate the fundamental group of the torus is, for n > 4, not contractible.

Spine Oncology – Primary Spine Tumors [PDF]

Neurosurgery, 2017
Abstract Primary tumors originating from the spine are very complex and challenging entities to treat. Due to their rarity, a multicenter collaborative network is essential to shepherd the best research and contribute to the dissemination of the best evidence possible.

Cortical composition hierarchy driven by spine proportion economical maximization or wire volume minimization [PDF]

PLoS Computational Biology 11(10): e1004532 (2015), 2015
The structure and quantitative composition of the cerebral cortex are interrelated with its computational capacity. Empirical data analyzed here indicate a certain hierarchy in local cortical composition. Specifically, neural wire, i.e., axons and dendrites take each about 1/3 of cortical space, spines and glia/astrocytes occupy each about $(1/3)^{2}$,

The ROCK inhibitor Fasudil prevents chronic restraint stress-induced depressive-like behaviors and dendritic spine loss in rat hippocampus [PDF]

, 2017
Indexación: Web of Science; Scopus.Background: Dendritic arbor simplification and dendritic spine loss in the hippocampus, a limbic structure implicated in mood disorders, are assumed to contribute to symptoms of depression.
