Scoliosis in Rett syndrome: a comparative analysis of postoperative complications.

Rett syndrome, a neurodevelopmental disorder primarily affecting females, presents unique challenges in managing associated scoliosis. This study aims to evaluate the efficacy and challenges of posterior spinal fusion (PSF) in Rett syndrome patients by analyzing postoperative complications. A retrospective cohort study was conducted using a large national database.

Deciphering the dual role of persistent luminescence materials: Toxicity and photoreception effects on rice development.

Studies on the toxicity of micro- and nanomaterials in plants have primarily focused on their intrinsic effects. However, there is often oversight when considering the potential perceptual responses that plants may exhibit in response to these materials. In this investigation, we assessed the impact of three commercially available persistent luminescence materials (PLMs) that emit red, green, or blue light under various environmental conditions.

Advances in Cas12a-Based Amplification-Free Nucleic Acid Detection.

In biomedicine, rapid and sensitive nucleic acid detection technology plays an important role in the early detection of infectious diseases. However, most traditional nucleic acid detection methods require the amplification of nucleic acids, resulting in problems such as long detection time, complex operation, and false-positive results. In recent years, clustered regularly interspaced short palindromic repeats (CRISPR) systems have been widely used in nucleic acid detection, especially the CRISPR-Cas12a system, which can trans cleave single-stranded DNA and can realize the detection of DNA targets.

Comparison of early and late postoperative outcomes between chordal reconstruction and quadrangular resection in patients with posterior mitral valve prolapse: a single-center retrospective study.

Background: To compare the early and late postoperative outcomes of chordal reconstruction (CR) and quadrangular resection (QR) in patients with posterior mitral valve prolapse (PMPL).

Methods: Between January 2008 and December 2018, 305 patients with PMPL who underwent mitral valve plasty (MVP) were included in this retrospective analysis. The CR and QR procedures were performed in 169 patients (CR group) and 136 patients (QR group), respectively.

Exendin-4 alleviates β-Amyloid peptide toxicity DAF-16 in a model of Alzheimer's disease.

Epidemiological analyses indicate that type 2 diabetes mellitus (T2DM) is a risk factor for Alzheimer's disease (AD). They share common pathophysiological mechanisms. Thus, it has been increasingly suggested that several anti-T2DM drugs may have therapeutic potential in AD.

A review of spectroscopic probes constructed from aptamer-binding gold/silver nanoparticles or their dimers in environmental pollutants' detection.

The issue of environmental pollutant residues has gained wide public attention all along. Therefore, it is necessary to develop simple, rapid, economical, portable, and sensitive detection techniques, which have become the focus of research in the pollutants detection field. Spectroscopy is one of the most convenient, simple, rapid, and intuitive analytical tools that can provide accurate information, such as ultraviolet spectroscopy, fluorescence spectroscopy, Raman spectroscopy, plasmon resonance spectroscopy, etc.

Clinical efficacy and safety of ultra-short-course chemotherapy in treatment of spinal tuberculosis after complete debridement: an observational study.

Objective: To evaluate the clinical efficacy and safety of ultra-short-course chemotherapy (<4 months) in treating spinal tuberculosis following complete debridement.

Methods: Clinical data of patients diagnosed with spinal tuberculosis, who underwent surgery with postoperative chemotherapy for < 4 months at the General Hospital of Ningxia Medical University between January 2005 and March 2015, were retrospectively analysed. Clinical manifestations, American Spinal Injury Association grades, states of bone fusion and lesion healing, deformity correction, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) levels and adverse drug reactions, observed before and after surgery and at the final follow-up, were assessed.

Banana Peel-Derived Dendrite-Shaped Au Nanomaterials with Dual Inhibition Toward Tumor Growth and Migration.

Purpose: In order to prepare functional Au nanoparticles with low toxicity and high antitumor properties, we have used fruit waste (banana peel) to synthesize a new dendrite-shaped gold nanoparticle and used it for the treatment of tumors.

Methods: Dendrite-shaped gold nanoparticle (Au-dendrite) was synthesized through a facile hydrothermal process. The banana peel was used as both the reducing agent and the protective agent for reducing chloroauric acid to obtain Au-dendrite.

Porous ZnO modified silk sutures with dual light defined antibacterial, healing promotion and controlled self-degradation capabilities.

Current sutures have disadvantages such as poor antibacterial activities, low healing effects, and a lack of self-degradation ability. To solve these problems, here a biocompatible and dual light (yellow and NIR light) responsive porous ZnO (PZ) was synthesized to modify silk thread to improve the healing rate, antibacterial activities and controlled self-degradation speed simultaneously. The prepared silk thread was characterized by using scanning electron microscopy (SEM) and X-ray diffractometry (XRD).

NaCl: for the safer in vivo use of antibacterial silver based nanoparticles.

Background: As antibiotics progressively cease to be effective, silver based nanoparticles (SBNs), with broad antibacterial spectrum, might be the last line of defense against malicious bacteria. Unfortunately, there are still no proper SBNs-based strategies for in vivo antibacterial therapies. In this article, new carbon membrane packaged Ag nanoparticles (Ag-C) were synthesized.

Risk of gastrointestinal complications in breast cancer patients treated with neratinib: a meta-analysis.

Backgrounds: Neratinib is a potent EGFR/HER2 kinase inhibitor. Gastrointestinal complications (i.e.

A highly efficient, low-toxic, wide-spectrum antibacterial coating designed for 3D printed implants with tailorable release properties.

Herein, a highly customized and broad-spectrum antibacterial implant was prepared through the combination of 3D printing technology and surface nano-modification. The antibacterial coating, which consists of the film-forming agent polyvinyl alcohol (PVA), polyethylene acid (PAA), and green-synthesized silver nanoparticles (Ag-NPs), was modified on the surface of a 3D-printed implant. The small-sized Ag-NPs (<10 nm) showed potent broad spectrum activity and good biocompatibility in relatively low concentration.

3D printed self-driven thumb-sized motors for in-situ underwater pollutant remediation.

Green fuel-driven thumb sized motors (TSM) were designed and optimized by 3D printing to explore their in-situ remediation applications in rare studied underwater area. Combined with areogel processing and specialized bacteria domestication, each tiny TSM could realize large area pollutant treatment precisely in an impressive half-automatically manner.

The first visually observable three-mode antibiotic switch and its relative 3D printing assisted applications.

The first visible three-mode switchable antibiotic nanocomposite, including "Packaged" (low toxicity and high stability), "On" (potent antibacterial activity, including drug-resistant strains) and "Off" (easy separation) modes, was synthesized to address several problems caused by antibiotic abuses. Some potential applications were discussed by using animal experiments and 3D printing separately.

Full Spectrum Visible LED Light Activated Antibacterial System Realized by Optimized Cu2O Crystals.

Assisted by three-dimensional printing technology, we proposed and demonstrated a full spectrum visible light activated antibacterial system by using a combination of 500 nm sized Cu2O crystals and light-emitting diode (LED) lamps. Further improved antibacterial ratios were achieved, for the first time, with pure Cu2O for both Gram-positive bacteria and Gram-negative bacteria among all of the six different color LED lamps. For practical antibacterial applications, we revealed that the nonwoven fabric could act as excellent carrier for Cu2O crystals and provide impressive antibacterial performance.

Notch1-mediated tumor suppression in cervical cancer with the involvement of SST signaling and its application in enhanced SSTR-targeted therapeutics.

The role of Notch signaling in cervical cancer is seemingly controversial. To confirm the function of Notch signaling in this type of cancer, we established a stable Notch1-activated cervical cancer HeLa cell line. We found that Notch1 activation resulted in apoptosis, cell cycle arrest, and tumor suppression.
