Photocatalytic reduction of CO (PCR) technology offers the capacity to transmute solar energy into chemical energy through an eco-friendly and efficacious process, concurrently facilitating energy storage and carbon diminution, this innovation harbors significant potential for mitigating energy shortages and ameliorating environmental degradation. Bismuth tungstate (BiWO) is distinguished by its robust visible light absorption and distinctive perovskite-type crystal architecture, rendering it highly efficiency in PCR. In recent years, numerous systematic strategies have been investigated for the synthesis and modification of BiWO to enhance its photocatalytic performance, aiming to achieve superior applications.

Background Context: Posterior percutaneous long-segment internal fixation and open fixation with long-segment screws have been used to treat thoracolumbar fractures in ankylosing spondylitis patients.

Purpose: To observe the clinical effect of posterior percutaneous long-segment internal fixation in 26 ankylosing spondylitis (AS) patients with thoracolumbar fractures.

Study Design: Retrospective cohort study.

Article Synopsis
  • The study is about how a substance called naringin helps protect cells in our back discs from damage caused by inflammation.
  • Naringin increases a process called autophagic flux, which helps keep cells healthy and reduces stress and inflammation.
  • The researchers found that naringin works by activating certain proteins (SIRT1 and AMPK) that support this protective process in the cells.

Background: Osteosarcoma (OS) is a common type of bone malignancy that often occurs in children and adolescents. Chemoresistance is a huge barrier to cancer therapy. This study aimed to investigate the role and potential mechanism of circ_0001721 in doxorubicin (DXR) resistance and OS development.

Background: This study aimed to explore the relationship among different cervical sagittal parameters in asymptomatic volunteers and the correlation between surgical efficacy and difference of presumed and actual postoperative C2-7 Cobbs's angle (C2-7COBB), which was calculated based on preoperative T1 slope (T1S) in patients undergoing cervical reconstruction.

Methods: In total, 158 inpatients with cervical spondylosis and 274 asymptomatic volunteers were retrospectively reviewed. Cervical sagittal parameters, such as C2-7COBB, T1S, thoracic inlet angle (TIA), and neck tilt (NT), were compared.

Worldwide research contributions have allowed the field of fracture surgery to progress. However, to the best of our knowledge, no studies have documented the main characteristics of publications from different countries. The present study aimed to determine the quantity and quality of worldwide research in fracture surgery.

Background: Xanthelasma palpebrarum (xanthelasma) is the most common type of cutaneous xanthoma, and many patients tend to seek medical treatments for cosmetic reasons. Many methods treating xanthelasma have been proposed, but none of these options can be regarded as a perfect solution.

Objective: To study and evaluate the intralesional injection treatment of xanthelasma with pingyangmycin, which has been widely used as a broad-spectrum antitumor antibiotic.

MG-63 human osteosarcoma cells were transfected with short hairpin RNA (shRNA) against livin and survivin using monomethoxypolyethylene glycol‑chitosan (mPEG‑CS) nanoparticles (NPs) as carriers, with the aim of evaluating the effect on cell proliferation and apoptosis. mPEG‑CS NPs sized ~100 nm were prepared by ionic crosslinking. mPEG‑CS‑livin shRNA, mPEG‑CS‑survivin shRNA and mPEG‑CS‑(livin shRNA + survivin shRNA) NPs were constructed by electrostatic adsorption at NP suspension/gene solution ratios of 3:1 to transfect MG‑63 cells.

Background: Loss of axial rotation and lateral bending after atlantoaxial fusion reduces a patient's quality of life. Therefore, effective, nonfusion fixation alternatives are needed for atlantoaxial instability.

Objective: To evaluate the initial stability and function of posterior atlantoaxial restricted nonfusion fixation (PAARNF), a new protocol, using cadaveric cervical spines compared with the intact state, destabilization, and posterior C1-C2 rod fixation.

Objective: To evaluate in a comprehensive biomechanical study the influences of fixed C1-C2 and different C1-C2 angles on the range of motion (ROM) and the intradiscal pressure (IDP) of subaxial cervical spine.

Methods: We simulated three-dimensional cervical motions on 8 human specimens with C1-C2 fixed in 3 different angles (neutral position, neutral position -10°, neutral position +10°) following intact analysis in the material test system. The ROM changes of each motion segment and the IDP changes of 4 subaxial motion segments (C2-C3, C3-C4, C4-C5, and C5-C6) were monitored.

It is well known that glucocorticoid (GC)-induced bone loss is caused primarily by hypofunction and apoptosis of osteoblasts. However, the precise molecular events underlying the effect of GC on osteoblast apoptosis are not fully understood. Recent studies implicated an important role of E4BP4 in the regulation of osteoblast apoptosis and differentiation.

Purpose: To verify the relationship between neurologic deficit after spinal cord injury without radiologic evidence of trauma (SCIWORET) and coexisting cervical disc herniation (CDH).

Methods: A retrospective review was made to compare the neurologic and radiological outcomes in SCIWORET patients with and without CDH. The neurologic deficit was evaluated by the American Spinal Injury Association (ASIA) scale at admission and last follow-up.

Purpose: The goal of this study was to determine which paraspinal approach provided a better transverse screw angle (TSA) for each vertebral level in lower lumbar surgery.

Methods: Axial computed tomography (CT) images of 100 patients, from L3 to S1, were used to measure the angulation parameters, including transverse pedicle angle (TPA) and transverse cleavage plane angle (TCPA) of entry from the two approaches. The difference value between TCPA and TPA, defined as difference angle (DA), was calculated.
