Ultrathin 2D Cu-Porphyrin MOF Nanosheet Loaded FeO Nanoparticles As a Multifunctional Nanoplatform for Synergetic Chemodynamic and Photodynamic Therapy Independent of O.

In this study, we developed a multifunctional nanoplatform to address the limitations of strictly acidic pH for the Fenton reaction involving FeO and the low efficiency of mono treatments. The hybrid material, FeO@Cu-TCPP, was assembled through hydrophobic interactions of polyvinylpyrrolidone (PVP) coated on its surface. The efficiency of the Fenton reaction using FeO was significantly enhanced by the photo-Fenton process in the presence of Cu-TCPP.

Impact of titanium mesh cage slotting width on anterior cervical corpectomy and fusion for compression cervical spondylosis with MRI T2WI hyperintensity: a one-year follow-up study.

Background: Anterior cervical corpectomy and fusion (ACCF) is a standard surgical procedure for cervical spondylosis with spinal cord compression (CSWSCC), especially in patients with intensity on T2-weighted imaging high signal (T2WIHS). The titanium mesh cage (TMC) utilized in this procedure is essential in stabilizing the spine; however, the optimal slotting width of the TMC remains unclear.

Objective: This study aimed to investigate the impact of TMC slotting width on the clinical and radiological outcomes of ACCF in patients with spinal cord compression type cervical spondylosis with intensity on T2WIHS (CST2WIHS).

Does two-level hybrid surgery promote early fusion compared with two-level anterior cervical discectomy and fusion?

Background Context: Hybrid surgery (HS), which involves both anterior cervical discectomy and fusion (ACDF) and cervical disc replacement (ACDR), is increasingly used to treat multilevel cervical disc degenerative disease, yielding satisfactory clinical outcomes. Early fusion is critical after anterior cervical fusion surgeries, but there are no studies comparing the rate of early fusion of HS with that of ACDF.

Purpose: The purpose of this study was to compare the rate of early fusion (3-6 months postoperatively) of two-level HS with that of two-level ACDF surgery.

Modelling and prediction of toluene adsorption saturation basing on characteristic values of activated carbons.

Herein, the association between the dynamic adsorption capacity of toluene and several important characteristic values on activated carbon (AC) samples was investigated by multidimensional linear regression. Among the characteristic values, the carbon tetrachloride (CTC) adsorption value has demonstrated relatively stronger correlation with the toluene adsorption capacity on AC samples with diverse sources and forms, particularly in exposure to high-concentration toluene. Notably, the relevance of the toluene adsorption capacity to the CTC value could also be extended to a series of other porous adsorbents, which proved the wide applicability of CTC value in characterizing the adsorption behaviors.

A comparative study of the effect of facet tropism on the index-level kinematics and biomechanics after artificial cervical disc replacement (ACDR) with Prestige LP, Prodisc-C vivo, and Mobi-C: a finite element study.

Introduction: Artificial cervical disc replacement (ACDR) is a widely accepted surgical procedure in the treatment of cervical radiculopathy and myelopathy. However, some research suggests that ACDR may redistribute more load onto the facet joints, potentially leading to postoperative axial pain in certain patients. Earlier studies have indicated that facet tropism is prevalent in the lower cervical spine and can significantly increase facet joint pressure.

Background: Artificial Cervical Disc Replacement (ACDR) is an effective treatment for cervical degenerative disc diseases. However, clinical information regarding the facet joint alterations after ACDR was limited. Facet tropism is common in the sub-axial cervical spine.

Methods: We conducted a retrospective study involving patients who underwent ACDF. A total of 55 patients were included in the analysis, including 110 OVB and 110 non-OVB.

Transcriptome Analysis Reveals the Molecular Mechanism and Responsive Genes of Waterlogging Stress in Planch Kiwifruit Plants.

Waterlogging stress is one of the major natural issues resulting in stunted growth and loss of agricultural productivity. Cultivated kiwifruits are popular for their rich vitamin C content and unique flavor among consumers, while commonly sensitive to waterlogging stress. The wild kiwifruit plants are usually obliged to survive in harsh environments.

Cervical Disc Arthroplasty for the Treatment of Noncontiguous Cervical Degenerative Disc Disease: Results of Mid- to Long-Term Follow-up.

Objective: The long-term results of cervical disc arthroplasty (CDA) for noncontiguous cervical degenerative disc disease (CDDD) are still uncertain. Moreover, it is unclear whether CDA delays or avoids the degeneration of the intermediate segment (IS), leading to controversy in the field. Therefore, this study aimed to investigate the mid- to long-term clinical and radiographic outcomes of CDA in treating noncontiguous CDDD and to explore whether the IS degenerated faster after CDA than other non-surgically treated adjacent segments.

Introduction: Cervical hybrid surgery (HS) combines anterior cervical discectomy and fusion (ACDF) and cervical disc arthroplasty (CDA) to establish an individualized surgical plan for patients with multiple cervical disc degenerative diseases. In order to maintain the stability of the spine after HS, an external cervical collar is often used. However, there is still controversy regarding the importance of a cervical collar following surgery.

Self-healing hydrogels for bone defect repair.

Severe bone defects can be caused by various factors, such as tumor resection, severe trauma, and infection. However, bone regeneration capacity is limited up to a critical-size defect, and further intervention is required. Currently, the most common clinical method to repair bone defects is bone grafting, where autografts are the "gold standard.
