Association of PLCE1 (rs7922612) and COL4A3 (rs375290088) Genetic Variants with the Risk of Nephrotic Syndrome in Egyptian Pediatric Patients.

Nephrotic syndrome is one of the most prevalent pediatric kidney illnesses seen in pediatric nephrology clinics. Steroid resistance in children with nephrotic syndrome is a primary cause of renal failure and is characterized by nephrotic range proteinuria that does not respond to conventional steroid therapy. The current work was intended to investigate the possible role of the Phospholipase C epsilon 1 (rs7922612) and collagen4 alpha 3 (rs375290088) single nucleotide polymorphisms as risk factors for developing nephrotic syndrome among Egyptian children. The study was conducted on 100 children with nephrotic syndrome and 100 age- and sex-matched healthy individuals. Geno typing was performed by two methods of polymerase chain reaction for the analysis of PLCE1 (rs7922612) and COL4A3 (rs375290088) variants. We observed a higher percentage of the heterozygous and homozygous variant genotypes of PLCE1 (rs7922612) SNP in NS patients in comparison with the controls (P < 0.001 for both). The frequencies of the PLCE1 (rs7922612) variant showed a statistically significant elevated risk of NS using several genetic models, including the dominant (OR = 9.12), recessive (OR = 2.31), and allelic (OR = 1.62) models (P < 0.001 for each). In addition, the PLCE1 (rs7922612) genotypes and alleles frequencies did not differ significantly between SRNS compared to SSNS cases. Furthermore, there was no significant difference regarding COL4A3 (rs375290088) polymorphism, neither between the NS and control groups nor between SDNS and SRNS. PLCE1 (rs7922612) is considered an independent risk factor for nephrotic syndrome in Egyptian pediatrics.COL4A3 (rs375290088) polymorphism is not correlated to Egyptian NS patients.

Developing an extended producer responsibility system for solid waste management in Jordan using multi-criteria decision-making approach.

To move from a traditional end of pipe approach into a more sustainable solid waste management system, the Jordanian Government has recently passed a set of new regulations The National Solid Waste Management Strategy has put a road map to encourage circular economy practices. One of the considered policy instruments is the adoption of the extended producer responsibility (EPR). The current study aimed to adopt a multi-criteria decision-making method to select the most convenient EPR structure within the Jordanian context. The study used analytical hierarchy process (AHP) and fuzzy AHP (FAHP) techniques to select the suitable type of producer responsibility organization (PRO) structure. A four-level hierarchy model was constructed with 4 criteria, 10 sub-criteria and 3 PRO alternatives. The analysis revealed that the legal and administrative criteria is the most important one (0.47) followed by environmental criteria (0.22), whereas the least important ones were socio-economic (0.17) and technical criteria (0.13). The most preferable PRO alternative was found to be PRO with profit. There were slight differences between all weight values under AHP and FAHP. Despite the availability of several laws, there is a need to develop the legal and administrative framework to enable the adoption of EPR in Jordan. Research should be the first step in the process of EPR system design. None of the previous studies conducted used the AHP and FAHP in assessing and selecting the EPR systems.

Exploring the impact of miR-128 in inflammatory diseases: A comprehensive study on autoimmune diseases.

microRNAs (miRNAs) play a crucial role in various biological processes, including immune system regulation, such as cell proliferation, tolerance (central and peripheral), and T helper cell development. Dysregulation of miRNA expression and activity can disrupt immune responses and increase susceptibility to neuroimmune disorders. Conversely, miRNAs have been shown to have a protective role in modulating immune responses and preventing autoimmunity. Specifically, reducing the expression of miRNA-128 (miR-128) in an Alzheimer's disease (AD) mouse model has been found to improve cognitive deficits and reduce neuropathology. This comprehensive review focuses on the significance of miR-128 in the pathogenesis of neuroautoimmune disorders, including multiple sclerosis (MS), AD, Parkinson's disease (PD), Huntington's disease (HD), epilepsy, as well as other immune-mediated diseases such as inflammatory bowel disease (IBD) and rheumatoid arthritis (RA). Additionally, we present compelling evidence supporting the potential use of miR-128 as a diagnostic or therapeutic biomarker for neuroimmune disorders. Collectively, the available literature suggests that targeting miR-128 could be a promising strategy to alleviate the behavioral symptoms associated with neuroimmune diseases. Furthermore, further research in this area may uncover new insights into the molecular mechanisms underlying these disorders and potentially lead to the development of novel therapeutic approaches.

Epidural Administration of Curcumin-Loaded Polycaprolactone/Gelatin Electrospun Nanofibers for Extended Analgesia After Laminectomy in Rats.

Several clinical studies have reported the analgesic effect of curcumin (Curc) in various situations such as rheumatoid arthritis, osteoarthritis, and postsurgical pain. Therefore, in this work, Curc-loaded electrospun nanofibers (NFs) are designed to evaluate their sustained release on analgesic effect duration in rats after epidural placement via repeated formalin and tail-flick tests. The Curc-loaded polycaprolactone/gelatin NFs (Curc-PCL/GEL NFs) are prepared through an electrospinning technique and introduced to the rat's epidural space after laminectomy. The physicochemical and morphology features of the prepared Curc-PCL/GEL NFs were characterized via FE-SEM, FTIR, and degradation assay. The in vitro and in vivo concentrations of Curc were measured to evaluate the analgesic efficacy of the drug-loaded NFs. Rat nociceptive responses are investigated through repeated formalin and tail-flick tests for 5 weeks after the placement of NFs. Curc had a sustained release from the NFs for 5 weeks, and its local pharmaceutical concentrations were much greater than plasma concentrations. Rat's pain scores in both early and late phases of the formalin test were remarkably decreased in the experimental period. Rat's tail-flick latency was remarkably enhanced and remained constant for up to 4 weeks. Our findings show that the Curc-PCL/GEL NFs can supply controlled release of Curc to induce extended analgesia after laminectomy.

Correlation of rs35753505 polymorphism in Neuregulin 1 gene with psychopathology and intelligence of people with schizophrenia.

BACKGROUND AND AIM: Schizophrenia is one of the most severe psychiatric disorders. About 0.5 to 1% of the world's population suffers from this non-Mendelian disorder. Environmental and genetic factors seem to be involved in this disorder. In this article, we investigate the alleles and genotypic correlation of mononucleotide rs35753505 polymorphism of Neuregulin 1 (NRG1), one of the selected genes of schizophrenia, with psychopathology and intelligence. MATERIALS AND METHODS: 102 independent and 98 healthy patients participated in this study. DNA was extracted by the salting out method and the polymorphism (rs35753505) were amplified by polymerase chain reaction (PCR). Sanger sequencing was performed on PCR products. Allele frequency analysis was performed using COCAPHASE software, and genotype analysis was performed using Clump22 software. RESULTS: According to our study's statistical findings, all case samples from the three categories of men, women, and overall participants significantly differed from the control group in terms of the prevalence of allele C and the CC risk genotype. The rs35753505 polymorphism significantly raised Positive and Negative Syndrome Scale (PANSS) test results, according to a correlation analysis between the two variables. However, this polymorphism led to a significant decrease in overall intelligence in case samples compared to control samples. CONCLUSION: In this study, it seems that the rs35753505 polymorphism of NRG1 gene has a significant role in the sample of patients with schizophrenia in Iran and also in psychopathology and intelligence disorders.

The Role of Ferroptosis in the Pathogenesis of Osteoarthritis.

Osteoarthritis (OA) is the most common type of arthritis. Its high prevalence, especially in the elderly, and its negative impact on physical function make it a leading cause of disability in the elderly. Joint pain as well joint stiffness are the common classic signs of OA. Chondrocyte death together with loss of articular cartilage integrity are the main pathologic changes in OA. Non-steroidal anti-inflammatory drugs (NSAIDs) and glucocorticoids are commonly used for the management of OA; still, their effectiveness is limited, and no therapeutic strategy is able to fully stop OA progression. Ferroptosis is a kind of cell death, distinct from apoptosis and necroptosis, caused by iron-dependent peroxidation of membrane phospholipids that terminates cell life by disintegrating all plasma membranes. It has been suggested that ferroptosis has a critical role in decreased viability of chondrocytes in OA, and here, we review recent findings regarding the pathologic pathways that lead to chondrocyte ferroptosis, and discuss the possible therapeutic utility of ferroptosis inhibition in OA.

Autophagy as a self-digestion signal in human cancers: Regulation by microRNAs in affecting carcinogenesis and therapy response.

Autophagy is defined as a "self-digestion" signal, and it is a cell death mechanism its primary function is degrading toxic agents and aged organelles to ensure homeostasis in cells. The basic leve ls of autophagy are found in cells, and when its levels exceed to standard threshold, cell death induction is observed. Autophagy dysregulation in cancer has been well-documented, and regulation of this pathway by epigenetic factors, especially microRNAs (miRNAs), is interesting and noteworthy. miRNAs are considered short endogenous RNAs that do not encode functional proteins, and they are essential regulators of cell death pathways such as apoptosis, necroptosis, and autophagy. Accumulating data has revealed miRNA dysregulation (upregulation or downregulation) during tumor progression, and their therapeutic manipulation provides new insight into cancer therapy. miRNA/autophagy axis in human cancers has been investigated an exciting point is the dual function of both autophagy and miRNAs as oncogenic and onco-suppressor factors. The stimulation of pro-survival autophagy by miRNAs can increase the survival rate of tumor cells and mediates cancer metastasis via EMT inductionFurthermore, pro-death autophagy induction by miRNAs has a negative impact on the viability of tumor cells and decreases their survival rate. The miRNA/autophagy axis functions beyond regulating the growth and invasion of tumor cells, and they can also affect drug resistance and radio-resistance. These subjects are covered in the current review regarding the new updates provided by recent experiments.

Effects of almond intake on oxidative stress parameters: A systematic review and meta-analysis of clinical trials.

BACKGROUND AND AIMS: Several randomized controlled trials (RCTs) have shown that almonds can improve oxidative stress indices, but the results are controversial. Therefore, the goal of this research was to carry out a systematic review and meta-analysis of all RCTs that evaluated the effect of almonds on selected oxidative stress indices. METHODS: A systematic search was conducted up to April 2022 on PubMed, Scopus, Web of Science, and Google Scholar. We have selected the studies that investigated the effects of almonds on malondialdehyde (MDA), and oxidized low-density lipoprotein (Ox-LDL) levels in adults. Data were pooled by using the random-effects model. The risk of bias in individual studies was assessed using the Cochrane Collaboration risk of bias tool. RESULTS: Seven RCTs involving 424 participants were analyzed. The results indicated that almond intake led to a significant decrease in MDA levels (WMD: - 6.63 nmol/ml; 95 % CI: - 8.72 to - 4.54; P < 0.001). However, no significant effect was observed on Ox-LDL (Hedges' g: - 0.12; 95 % CI: - 0.34 to 0.10; P = 0.28). Sensitivity analysis showed that overall estimates were not affected by the elimination of any study. We did not observe any evidence regarding publication bias. CONCLUSION: The present meta-analysis suggests that almond intake can improve MDA levels and might play a beneficial role in the reinforcement of the antioxidant defense system and amelioration of oxidative stress in adults. There is a need for more studies with larger groups to better estimate this effect.

Microplastic and oil pollutant agglomerates synergistically intensify toxicity in the marine fish, Asian seabass, Lates calcalifer.

Asian seabass, Lates calcarifer frys were exposed to polystyrene (MP: 0.5 mg/l), oil (0.83 ml/l) and agglomerates (MP + oil + Corexit) as eight treatments in three replicates, and fresh synthetic marine water (control) for 15 days. The synergistic effect was confirmed (P ˂ 0.05) by bio-indicators including RBC count, total plasma protein, aspartate aminotransferase (AST), catalase (CAT), glutathione S-transferase (GST), basophils, thrombocyte and eosinophils percentages. Most of the significant and synergistic effects were observed in the highest doses (5 mg/l MP and 5 mg/l MP-oil-dispersant). Exposure to MP and a combination of MP+ oil caused tissue lesions in gill, liver and intestine. Our results suggest there are no critical health issues for Asian seabass in natural environments. However, the bioaccumulation of MPs, oil, and their agglomerates in consumers' bodies may remain a concern.

Implications of biomimetic nanocarriers in targeted drug delivery.

Nanomaterials and nanostructures have shown fascinating performances in various biomedicine fields, from cosmetic to cancer diagnosis and therapy. Engineered nanomaterials can encapsulate both lipophilic and hydrophilic substances/drugs to eliminate their limitations in the free forms, such as low bioavailability, multiple drug administration, off-target effects, and various side effects. Moreover, it is possible to deliver the loaded cargo to the desired site of action using engineered nanomaterials. One approach that has made nanocarriers more sophisticated is the "biomimetic" concept. In this scenario, biomolecules (e.g., natural proteins, peptides, phospholipids, cell membranes) are used as building blocks to construct nanocarriers and/or modify agents. For instance, it has been reported that specific cells tend to migrate to a particular site during specific circumstances (e.g., inflammation, tumor formation). Employing the cell membrane of these cells as a coating for nanocarriers confers practical targeting approaches. Accordingly, we introduce the biomimetic concept in the current study, review the recent studies, challenge the issues, and provide practical solutions.

MicroRNA-32 Suppression: its Effects on Prostate Cancer Cells' Capability to Proliferate and Migrate.

INTRODUCTION: This paper sought to scrutinize the role of microRNA-32 (miR-32) on the growth and migration as well as on the expression of metastatic genes in PC3 cells of prostate cancer in vitro. METHODS: Subsequent transfection of cells with miR-32 mimics, miR-32 inhibitor, negative control (NC), cell proliferation using MTT, and apoptosis by ELISA were performed. Furthermore, qRT-PCR was directed to measure the expression levels of matrix metalloproteinase 2 (MMP2) and vascular endothelial growth factors (VEGF) as metastatic and angiogenesis genes in the progression of PC3. RESULTS: miR-32 was overexpressed in PC3 cells compared to normal cells (P<0.001). Down-regulation of miR-32 obstructs in vitro proliferation and migration while intensifying the apoptosis rate in PC3 cells. Also, we found that miR-32 negatively modulates the expression of VEGF and MMP2 in PC3 cells. CONCLUSION: These results indicate that the suppression of miR-32 might offer an auxiliary treatment procedure for addressing the invasion, progression, and metastasis in PCa patients by improving cell apoptosis.

The role of endoplasmic reticulum stress in endometriosis.

Endometriosis is a chronic gynecologic disorder characterized by abnormal growth of endometrium-like tissues in the ectopic regions of the pelvic peritoneum. The pathophysiology of endometriosis is not completely understood; however, excessive endometrial cell proliferation together with resistance to apoptosis facilitates the migration, implantation, and survival of endometrial cells in the distant sites. Endoplasmic reticulum (ER) stress response (also called unfolded protein response) is a cellular defense mechanism triggered by ER stress. When severe enough, the so-called response initiates cell suicide, i.e., apoptosis. Therefore, therapeutic induction of ER stress in endometriotic cells could promote apoptosis and contribute to the management of disease. In this review, we discuss the pathogenic role of ER stress in endometriosis and the most recent findings regarding the induction of ER stress in connection with endometriosis.

Long non-coding RNAs: The modulators of innate and adaptive immune cells.

Before very sensitive current genomics platforms were discovered, long non-coding RNAs (lncRNAs) as controllers of gene expression, were thought to be accumulated genetic garbage. The past few years have seen a lot of interest in a large classification of non-coding transcripts with an indeterminate length of more than 200 nucleotides [1]. lncRNAs' association with immunity and disease progression has been revealed by a growing body of experimental research. Only a limited subset of lncRNAs, however, has solid proof of their role. It is also clear that various immune cells express lncRNAs differently. In this review, we concentrated on the role of lncRNA expression in the regulation of immune cell function and response to pathological conditions in macrophages, dendritic cells, natural killer (NK) cells, neutrophils, Myeloid-derived suppressor cells (MDSCs), T cells, and B cells. The innate and adaptive immune response systems may be significantly regulated by lncRNAs, according to emerging research. To discover possible therapeutic targets for the therapy of different diseases, it may be helpful to have a better realization of the molecular mechanisms beyond the role of lncRNAs in the immune response. Therefore, it is crucial to investigate lncRNA expression and comprehend its significance for the immune system.

In Vivo and In Vitro Biocompatibility Study of CuS Nanoparticles: Photosensitizer for Glioblastoma Photothermal Therapy.

Although photothermal treatment (PTT) has made significant progress in the fight against cancer, certain types of malignant tumors are still difficult to eradicate. PTT uses photothermal transforming agents to absorb NIR light and convert it to thermal energy, causing cancer cell death. In this study, we synthesized alginate (Alg)-coated CuS nanoparticles (CuS@Alg) as photothermal transforming agents to kill glioblastoma cancer cells. Nanoparticles were synthesized via a facile method, then, were characterized with different techniques such as ultraviolet-visible spectroscopy (UV-Vis), Fourier transform infrared (FTIR), X-ray diffraction analysis (XRD), transmission electron microscopy (TEM), and dynamic light scattering (DLS). Nanoparticles show high stability, and are monodisperse. CuS@Alg was discovered to have a spherical shape, a hydrodynamic size of about 19.93 nm, and a zeta potential of - 9.74 mV. CuS@Alg is able to increase temperature of medium under NIR light. Importantly, in vitro investigations show that PTT based on CuS@Alg has a strong theraputic impact, resulting in much high effectiveness. The LD50 and histopathology assays were used to confirm the NPs' non-toxicity in vivo. Results from an in vivo subacute toxicity investigation showed that the fabricated NPs were perfectly safe to biomedical usage.

Trace elements-based Auroshell gold@hematite nanostructure: Green synthesis and their hyperthermia therapy.

Hyperthermia is an additional treatment method to radiation therapy/chemotherapy, which increases the survival rate of patients without side effects. Nowadays, Auroshell nanoparticles have attracted much attention due to their precise control over heat use for medical purposes. In this research, iron/gold Auroshell nanoparticles were synthesised using green nanotechnology approach. Auroshell gold@hematite nanoparticles were synthesised and characterised with rosemary extract in one step and the green synthesised nanoparticles were characterised by X-ray powder diffraction, SEM, high-resolution transmission electron microscopy, and X-ray photoelectron spectroscopy analysis. Cytotoxicity of Auroshell iron@gold nanoparticles against normal HUVEC cells and glioblastoma cancer cells was evaluated by 2,5-diphenyl-2H-tetrazolium bromide method, water bath hyperthermia, and combined method of water bath hyperthermia and nano-therapy. Auroshell gold@hematite nanoparticles with minimal toxicity are safe against normal cells. The gold shell around the magnetic core of magnetite caused the environmental and cellular biocompatibility of these Auroshell nanoparticles. These magnetic nanoparticles with targeted control and transfer to the tumour tissue led to uniform heating of malignant tumours as the most efficient therapeutic agent.

Carbon nanoparticles-based hydrogel nanocomposite induces bone repair in vivo.

The main objective of the current study is to fabricate a 3D scaffold using alginate hydrogel implemented with carbon nanoparticles (CNPs) as the filler. The SEM imaging revealed that the scaffold possesses a porous internal structure with interconnected pores. The swelling value of the scaffolds (more than 400%) provides a wet niche for bone cell proliferation and migration. The in vitro evaluations showed that the scaffolds were hemocompatible (with hemolysis induction lower than 5%) and cytocompatible (inducing significant proliferative effect (cell viability of 121 ± 4%, p < 0.05) for AlG/CNPs 10%). The in vivo studies showed that the implantation of the fabricated 3D nanocomposite scaffolds induced a bone-forming effect and mediated bone formation into the induced bone defect. In conclusion, these results implied that the fabricated NFC-integrated 3D scaffold exhibited promising characteristics beneficial for bone regeneration and can be applied as the bone tissue engineering scaffold.
