Mangiferin mitigates methotrexate-induced liver injury and suppresses hepatic stellate cells activation in rats: Imperative role of Nrf2/NF-κB/NLRP3 signaling axis.

Ethnopharmacological Relevance: Mangifera indica (family Anacardiaceae), often acknowledged as mango and renowned for being a plant of diverse ethnopharmacological background since ancient times, harbors the polyphenolic bioactive constituent, mangiferin (MNG). MNG is a major phytochemical of Mangifera indica and other plants with a wide range of reported pharmacological activities, including antioxidant, anti-inflammatory, neuroprotective and hepatoprotective effects. MNG has also been utilized in traditional medicine; it is reportedly a major bioactive element in over 40 polyherbal products in traditional Chinese medicine (TCM), and two prominent anti-inflammatory, immunomodulatory and antiviral Cuban formulations.

Catheters linked thrombosis in neonates: a single center observational study.

Background: Central venous catheters (CVCs) are the major risk factors for neonatal thrombosis that might negatively affect morbidity and mortality in neonates. The aim of the present work was to estimate the incidence of CVC-linked thrombosis, among neonates in the NICU of Alexandria University Maternity Hospital, Egypt, over 1year, and to determine its possible risk factors.

Methods: This observational cohort study involved 134 newborn infants born from July 2020 to July 2021with CVCs insertion during their hospital stay.

Prevalence of antimicrobial-resistant bacteria in conventional vs. organic livestock farms in Egypt: a cross-sectional comparative study.

The silent pandemic of antimicrobial resistance (AR) has been on the rise for the past decades. It is essential to determine the burden of AR in animal farms that spreads leading to human exposure. A total of 100 samples including soil, litter, animal excreta, and wastewater were collected from seven conventional and one organic farm in Egypt.

Placental Macrophages Demonstrate Sex-Specific Response to Intrauterine Inflammation and May Serve as a Marker of Perinatal Neuroinflammation.

Preterm birth (PTB) is considered to be one of the most frequent causes of neonatal death. Prompt and effective measures to predict adverse fetal outcome following PTB are urgently needed. Placenta macrophages are a critical immune cell population during pregnancy, phenotypically divided into M1 and M2 subsets.

Fetal Neuroprotective Strategies: Therapeutic Agents and Their Underlying Synaptic Pathways.

Synaptic signaling is integral for proper brain function. During fetal development, exposure to inflammation or mild hypoxic-ischemic insult may lead to synaptic changes and neurological damage that impairs future brain function. Preterm neonates are most susceptible to these deleterious outcomes.

Pregnancy alters interleukin-1 beta expression and antiviral antibody responses during severe acute respiratory syndrome coronavirus 2 infection.

Background: Severe acute respiratory syndrome coronavirus 2, the disease-causing pathogen of the coronavirus disease 2019 pandemic, has resulted in morbidity and mortality worldwide. Pregnant women are more susceptible to severe coronavirus disease 2019 and are at higher risk of preterm birth than uninfected pregnant women. Despite this evidence, the immunologic effects of severe acute respiratory syndrome coronavirus 2 infection during pregnancy remain understudied.

The effect of intrauterine inflammation on mTOR signaling in mouse fetal brain.

Fetuses exposed to an inflammatory environment are predisposed to long-term adverse neurological outcomes. However, the mechanism by which intrauterine inflammation (IUI) is responsible for abnormal fetal brain development is not fully understood. The mechanistic target of rapamycin (mTOR) signaling pathway is closely associated with fetal brain development.

Genetic Influence on Efficacy of Pharmacotherapy for Pediatric Attention-Deficit/Hyperactivity Disorder: Overview and Current Status of Research.

Multiple stimulant and non-stimulant medications are approved for the treatment of attention-deficit/hyperactivity disorder (ADHD), one of the most prevalent childhood neurodevelopmental disorders. Choosing among the available agents and determining the most effective ADHD medication for a given child can be a time-consuming process due to the high inter-individual variability in treatment efficacy. As a result, there is growing interest in identifying predictors of ADHD medication response in children through the burgeoning field of pharmacogenomics.

MicroRNA inhibition upregulates hippocampal A-type potassium current and reduces seizure frequency in a mouse model of epilepsy.

Epilepsy is often associated with altered expression or function of ion channels. One example of such a channelopathy is the reduction of A-type potassium currents in the hippocampal CA1 region. The underlying mechanisms of reduced A-type channel function in epilepsy are unclear.

The fetal origins of mental illness.

The impact of infections and inflammation during pregnancy on the developing fetal brain remains incompletely defined, with important clinical and research gaps. Although the classic infectious TORCH pathogens (ie, Toxoplasma gondii, rubella virus, cytomegalovirus [CMV], herpes simplex virus) are known to be directly teratogenic, emerging evidence suggests that these infections represent the most extreme end of a much larger spectrum of injury. We present the accumulating evidence that prenatal exposure to a wide variety of viral and bacterial infections-or simply inflammation-may subtly alter fetal brain development, leading to neuropsychiatric consequences for the child later in life.

Vancomycin resistance among isolates in a rural setting, Egypt.

Introduction: With the increased occurrence of methicillin resistant (MRSA), the consumption of vancomycin, the drug of choice, has also increased. As a consequence, strains of resistant to vancomycin have started to emerge. This study aimed to evaluate the level of vancomycin resistance among clinical and nasal isolates in a rural town in Egypt.

Isoform-selective phosphoinositide 3-kinase inhibition ameliorates a broad range of fragile X syndrome-associated deficits in a mouse model.

Defects in the phosphoinositide 3-kinase (PI3K) pathway are shared characteristics in several brain disorders, including the inherited intellectual disability and autism spectrum disorder, fragile X syndrome (FXS). PI3K signaling therefore could serve as a therapeutic target for FXS and other brain disorders. However, broad inhibition of such a central signal transduction pathway involved in essential cellular functions may produce deleterious side effects.

Using ADHD Medications to Treat Coexisting ADHD and Reading Disorders: A Systematic Review.

Attention-deficit/hyperactivity disorder (ADHD), the most common pediatric neurobehavioral disorder, frequently presents with coexisting reading disorders (RDs). Despite this, it is unclear whether medication improves symptoms and function in children with comorbid ADHD and RD. We present a systematic review of studies investigating the effects of ADHD medications on ADHD symptoms, academic outcomes, and neuropsychological measures in this important group.

Design and analysis of siloxanes removal by adsorption from landfill gas for waste-to-energy processes.

Separation of volatile methyl siloxanes from landfill gas using fixed adsorption beds was modeled with the objective of identifying appropriate technology and the economics associated with this purification step. A general adsorption model assuming plug flow and radial symmetry was developed and used to conduct a parametric sweep of 162 unique cases. The varied parameters were adsorbent type (activated carbon and silica gel), bed height (3.

Requirements, techniques, and costs for contaminant removal from landfill gas.

Waste-to-energy projects are an increasingly prominent component of future energy portfolios. Landfill gas (LFG)-to-energy (LFGTE) projects are particularly important as they address greenhouse gas emissions. Contaminants in LFG may hamper these projects both from environmental and economic standpoints.
