Beliefs and attitudes of Syrian refugee mothers in Lebanon regarding children vaccination: a cross-sectional study.

Background: Vaccines have contributed to the disappearance of various diseases, and almost eradicated others across the world. Studies have shown that in Lebanon a profoundly small percentage of Syrian refugee children were fully immunized by routine vaccination services. Exploring the knowledge, attitudes, and practices of parents towards vaccination is of crucial importance, given the role of parents in children's immunization.

Silencing c-myc gene by siRNA delivered by cationic niosomes in MCF-7 cells.

Objectives: Gene therapy has a strong potential to treat different cancer types cancers with high therapeutic outcomes. c-myc is believed to be responsible for more than 15% of all gene regulation and functions as a transcription factor for proteins essential for cell proliferation. This study aimed to develop niosome nanocarriers to knockdown c-myc expression using anti-c-myc short-interfering RNA (siRNA) in MCF-7 cells.

The long-term effects of limbic non-convulsive status epilepticus in peri-adolescent rats.

To optimize the clinical approach to non-convulsive status epilepticus (NCSE), it is essential to gain insight into its long-term effects on cognition and behaviors. Here, we investigated limbic NCSE-induced hippocampal injury and behavioral deficits in peri-adolescent rats. NCSE was induced in P43 Sprague Dawleyrats with intrahippocampal subconvulsive doses of kainic acid (NCSE group, n = 14) under continuous epidural cortical electroencephalography (EEG).

High Diagnostic Yield and Clinical Utility of Next-Generation Sequencing in Children with Epilepsy and Neurodevelopmental Delays: A Retrospective Study.

Advances in genetics led to the identification of hundreds of epilepsy-related genes, some of which are treatable with etiology-specific interventions. However, the diagnostic yield of next-generation sequencing (NGS) in unexplained epilepsy is highly variable (10-50%). We sought to determine the diagnostic yield and clinical utility of NGS in children with unexplained epilepsy that is accompanied by neurodevelopmental delays and/or is medically intractable.

All specimens were retreated with ProTaper Universal Retreatment System files then divided to three different groups according to the technique of activation of irrigation.

Inkjet-Printed, Flexible Organic Electrochemical Transistors for High-Performance Electrocorticography Recordings.

Organic electrochemical transistors (OECTs) have emerged as powerful tools for biosignal amplification, including electrocorticography (ECoG). However, their widespread application has been limited by the complexities associated with existing fabrication techniques, restricting accessibility and scalability. Here, we introduce a novel all-planar, all-printed high-performance OECT device that significantly enhances the accuracy and sensitivity of ECoG recordings.

Customizable Microfluidic Devices: Progress, Constraints, and Future Advances.

The field of microfluidics encompasses the study of fluid behavior within micro-channels and the development of miniature systems featuring internal compartments or passageways tailored for fluid control and manipulation. Microfluidic devices capitalize on the unique chemical and physical properties exhibited by fluids at the microscopic scale. In contrast to their larger counterparts, microfluidic systems offer a multitude of advantages.

Prefrontal cortex neurons encode ambient light intensity differentially across regions and layers.

While light can affect emotional and cognitive processes of the medial prefrontal cortex (mPFC), no light-encoding was hitherto identified in this region. Here, extracellular recordings in awake mice revealed that over half of studied mPFC neurons showed photosensitivity, that was diminished by inhibition of intrinsically photosensitive retinal ganglion cells (ipRGCs), or of the upstream thalamic perihabenular nucleus (PHb). In 15% of mPFC photosensitive neurons, firing rate changed monotonically along light-intensity steps and gradients.

Imiquimod Reverses Chronic Toxoplasmosis-Associated Behavioral and Neurocognitive Anomalies in a Rat Model.

is the etiologic agent of toxoplasmosis, a highly prevalent parasitosis. () transits in the brain from acute (AT) to chronic toxoplasmosis (CT), under host immune control. In immunocompromised patients, reactivation of CT is potentially life-threatening.

Nanomaterial-Driven Precision Immunomodulation: A New Paradigm in Therapeutic Interventions.

Immunotherapy is a rapidly advancing field of research in the treatment of conditions such as cancer and autoimmunity. Nanomaterials can be designed for immune system manipulation, with precise targeted delivery and improved immunomodulatory efficacy.

The influence of intraoral cryotherapy on postoperative pain and substance P in symptomatic apical periodontitis: randomized clinical study.

Cryotherapy is widely utilized in medicine, particularly for pain management. This randomized clinical trial aimed to assess the effect of intraoral cold pack application (cryotherapy) on postoperative pain (POP) and the level of Substance P (SP) in patients with symptomatic apical periodontitis (SAP). Enrolled patients were randomly assigned to either cryotherapy or control group.

Hydrogen Adsorption on Type-5 Penta-MgN Sheet, Nanotube, and 3D Porous Structure.

Motivated by the recent report on penta-MgN sheet [ , 38, 101259] that is the first realization of type-5 pentagonal 2D tessellation with exposed regularly distributed Mg ions, we carried out density functional theory studies on the interactions of H molecules with 1D penta-nanotube, 2D penta-sheet, and 3D porous structures based on penta-MgN. We found that when the penta-MgN sheet is assembled to a 3D porous structure or curved to a nanotube, the bandgap increases from 1.18 to 1.

Primary prophylaxis with mTOR inhibitor enhances T cell effector function and prevents heart transplant rejection during talimogene laherparepvec therapy of squamous cell carcinoma.

The application of mammalian target of rapamycin inhibition (mTORi) as primary prophylactic therapy to optimize T cell effector function while preserving allograft tolerance remains challenging. Here, we present a comprehensive two-step therapeutic approach in a male patient with metastatic cutaneous squamous cell carcinoma and heart transplantation followed with concomitant longitudinal analysis of systemic immunologic changes. In the first step, calcineurin inhibitor/ mycophenolic acid is replaced by the mTORi everolimus to achieve an improved effector T cell status with increased cytotoxic activity (perforin, granzyme), enhanced proliferation (Ki67) and upregulated activation markers (CD38, CD69).

Estimation of alpha exposure on CR-39 detector using a UV-VIS spectrophotometer.

This work is dedicated to study the possibility of using UV-VIS spectrophotometer, a non-invasive technique with a versatile applications that is being used to determine the optical properties of matter, to estimate the CR-39 exposure to alpha particles. CR-39 detectors were exposed to alpha particles from two different alpha sources: Am and radon gas. Tracks densities on CR-39 were determined using the traditional counting method by an optical microscope.
