Standardizing postoperative pain control for decompression of pediatric Chiari type I malformation by limiting narcotic usage.

Objective: The aim of this study was to assess the effectiveness of a postoperative multimodal pain control protocol on perioperative pain scores in children undergoing decompression for Chiari type I malformation (CM-I).

Methods: This retrospective matched cohort study included patients < 21 years of age who underwent elective suboccipital craniectomy and C1 laminectomy for CM-I with or without duraplasty at a single center from January 2020 to July 2023. A standardized, multimodal postoperative pain protocol was implemented in August 2021 that did not use narcotic patient-controlled analgesia.

Metal-Organic Frameworks MIL-101(Fe) and MIL-53(Al) as Efficient Adsorbents for Dispersive Micro-Solid-Phase Extraction of Sorafenib in Plasma and Wastewater, Coupled with HPLC-UV Analysis.

In the present study, metal-organic frameworks, MIL-101(Fe) and MIL-53(Al), were synthesized under solvothermal conditions and were characterized by Fourier transform infrared spectroscopy, X-ray energy diffraction spectroscopy and scanning electron microscopy. The synthesized metal-organic frameworks were utilized for the purpose of dispersive micro-solid phase extraction of sorafenib in both human plasma and wastewater, which was subsequently followed by high performance liquid chromatography with ultraviolet determination. Parameters affecting extraction efficacy including adsorbent amount, ionic strength, pH, type of elution solvent, adsorption and desorption time were optimized.

Design, synthesis, and structure-activity relationships of five-membered heterocyclic incorporated aryl(alkyl)azoles: From antiproliferative thiazoles to safer anticonvulsant oxadiazoles.

In the current study, a novel series of 1,2,4-oxadiazoles were designed, synthesized, and evaluated for their biological activities. A cell-based antiproliferative screening was accomplished on the newly synthesized 1,2,4-oxadiazoles along with our previously reported aryl(alkyl)azoles (AAAs) containing middle heterocyclic cores thiazole and oxazole. Among the tested compounds, naphthyl- thiazoles demonstrated higher antiproliferative activity and B3 was identified as the most potent compound with IC values in the range of 2.

Methods: A cross-sectional multicenter study was conducted among 346 patients with chronic kidney disease (CKD) covered by the Iran Health Insurance Organization who received dialysis services from October to December 2022 across the country.

Gene expression levels associated with impaired immune response and increased proliferation could serve as biomarkers for women following cervical cancer screening programmes.

Human papilloma virus (HPV) infections vary in their oncogenic potential, and whether an infection progresses to cervical intraepithelial neoplasia (CIN) also depends on the immune response. Therefore, the aim of the present study was to explore biomarkers related to the immune system and cell proliferation, in combination with HPV classified as having high (HOP) or low oncogenic potential (LOP), that can possibly guide a more accurate identification of women following cervical cancer screening programmes in need for immediate follow-up with a biopsy. A next-generation sequencing transcriptomic immune profile analysis applied to 28 persistent CIN3 lesions and 14 normal biopsies identified four genes, the immune markers and and the tumour markers and , as possible markers for differentiating between CIN3 and normal tissue.

Systematic review of microRNAs in human acute kidney injury.

Introduction: Early diagnosis of acute kidney injury (AKI) is limited with current tools. MicroRNAs (miRNAs) are implicated in AKI pathogenesis in preclinical models, but less is known about their role in humans. We conducted a systematic review to identify dysregulated miRNAs in humans with AKI.

Design of Alginate/Gelatin Hydrogels for Biomedical Applications: Fine-Tuning Osteogenesis in Dental Pulp Stem Cells While Preserving Other Cell Behaviors.

Alginate/gelatin (Alg-Gel) hydrogels have been used experimentally, associated with mesenchymal stromal/stem cells (MSCs), to guide bone tissue formation. One of the main challenges for clinical application is optimizing Alg-Gel stiffness to guide osteogenesis. In this study, we investigated how Alg-Gel stiffness could modulate the dental pulp stem cell (DPSC) attachment, morphology, proliferation, and osteogenic differentiation, identifying the optimal conditions to uncouple osteogenesis from the other cell behaviors.

BEAS-Net: a Shape-Prior-Based Deep Convolutional Neural Network for Robust Left Ventricular Segmentation in 2D Echocardiography.

Left ventricle (LV) segmentation of 2D echocardiography images is an essential step in the analysis of cardiac morphology and function and - more generally - diagnosis of cardiovascular diseases. Several deep learning (DL) algorithms have recently been proposed for the automatic segmentation of the LV, showing significant performance improvement over the traditional segmentation algorithms. However, unlike the traditional methods, prior information about the segmentation problem, e.

Cell-based shear stress sensor for bioprocessing.

Shear stress during bioreactor cultivation has significant impact on cell health, growth, and fate. Mammalian cells, such as T cells and stem cells, in next-generation cell therapies are especially more sensitive to shear stress present in their culture environment than bacteria. Therefore, a base knowledge about the shear stress imposed by the bioprocesses is needed to optimize the process parameters and enhance cell growth and yield.

Acid-based deep eutectic solvents followed by GFAAS for the speciation of As(III), As(V), total inorganic arsenic and total arsenic in rice samples.

In the present study, an efficacious, safe, inexpensive and eco-friendly microextraction was provided by deep eutectic solvents based on dispersive liquid-liquid microextraction (DLLME - DES) followed by GFAAS. A series of DESs were synthesised using -menthol as hydrogen bond acceptor (HBA) and carboxylic acids with 4, 6, 8 and 10 carbon atoms as hydrogen bond donors (HBD).
