tae-miR399- Module Enhances Freezing Tolerance in Winter Wheat via a CBF Signaling Pathway.

Although the regulation of Pi homeostasis by miR399 has been studied in various plant species, its underlying molecular mechanism in response to freezing stress is still poorly understood. In this work, we found that the expression of tae-miR399 and its target gene in the tillering nodes of the strong cold-resistant winter wheat cultivar Dongnongdongmai1 (Dn1) was not only significantly altered after severe winters but also responsive to short-term freezing stress. TaUBC24 physically interacted with TaICE1.

Relationship of Change in Cervical Curvature after Laminectomy with Lateral Mass Screw Fixation to Spinal Cord Shift and Clinical Efficacy.

Background And Study Aims:  Although laminectomy with lateral mass screw fixation (LCSF) is an effective surgical treatment for cervical spondylotic myelopathy (CSM), loss of cervical curvature may result. This study aimed to investigate the effect of cervical curvature on spinal cord drift distance and clinical efficacy.

Patients And Methods:  We retrospectively analyzed 78 consecutive CSM patients with normal cervical curvature who underwent LCSF.

Modified grade 4 osteotomy for the correction of post-traumatic thoracolumbar kyphosis: A retrospective study of 42 patients.

The roles of inflammatory cytokines in the pathogenesis of ossification of ligamentum flavum.

Ossification of Ligamentum Flavum (OLF) is associated with serious neurologic symptoms including thoracic myelopathy and spinal stenosis. The pathogenesis of thoracic OLF is mainly due to the localized mechanical stress on the ligament induced enchondral ossification. However, despite numerous epidemiological and basic science studies, the mechanism of this process remains unclear.
