Background: Bioelectronic medicines aim to diagnose and treat a wide range of illnesses and ailments, including cancer, rheumatoid arthritis, inflammatory bowel disease, obesity, diabetes, asthma, paralysis, blindness, bleeding, ischemia, organ transplantation, cardiovascular disease, and neurodegenerative diseases. The focus of bioelectronic medicine is on electrical signaling of the nervous system. Understanding the nervous system's regulatory roles and developing technologies that record, activate, or inhibit neural signaling to influence particular biological pathways.

Objective: Bioelectronic medicine is an emerging therapeutic option with the interconnection between molecular medicine, neuroscience, and bioengineering. The creation of nerve stimulating devices that communicate with both the central and peripheral nervous systems has the potential to completely transform how we treat disorders. Although early clinical applications have been largely effective across entire nerves, the ultimate goal is to create implantable, miniature closed-loop systems that can precisely identify and modulate individual nerve fibers to treat a wide range of disorders.

Methodology: The data bases such as PubMed, and Clinicaltrial.gov.in were searched for scientific research, review and clinical trials on bioelectronic medicine.

Conclusion: The field of bioelectronic medicine is trending at present. In recent years, researchers have extended the field's applications, undertaken promising clinical trials, and begun delivering therapies to patients, thus creating the groundwork for significant future advancements. Countries and organizations must collaborate across industries and regions to establish an atmosphere and guidelines that foster the advancement of the field and the fulfillment of its prospective advantages.

A double bond between the nitrogen and carbon atoms characterizes a wide class of compounds known as Schiff bases. The flexibility of Schiff bases is formed from several methods and may be combined with alkyl or aryl substituents. The group is a part of organic compounds, either synthetic or natural, and it serves as a precursor and an intermediate in drugs that have therapeutic action. The review focuses on molecular docking and structure-activity relationship (SAR) analysisfor antidiabetic effects of the different non-metal Schiff bases. Many studies have found that Schiff bases are used as linkers in an extensive range of synthesized compounds and other activities. Thus, this current study aims to give the scientific community a thoughtful look at the principal ideas put forward by investigators regarding antidiabetic actions exhibited by certain Schiff-based derivatives, as this review covered many aspects, including docking and SAR analysis. For individuals who intend to create novel antidiabetic compounds with Schiff bases as pharmacophores or physiologically active moieties, it will be an invaluable informational resource.

Hepatocellular carcinoma (HCC) is influenced by several factors, among which genetic polymorphisms play a key role. Polymorphisms in various genes affect key pathways involved in HCC development, including metabolism, expression of inflammatory cytokines, cell proliferation, and apoptosis regulation. These polymorphisms induce differential effects on susceptibility to HCC, disease progression, and treatment outcomes. Understanding the effect of genetic variations on HCC pathogenesis is essential to elucidate underlying mechanisms and identify potential therapeutic targets. This review explores the diverse roles of genetic polymorphisms in HCC, providing insights into the complex interplay between genetic factors and disease development.

Nowadays, the usage of probiotics in the food industry has become common. It has been proven that probiotics have many health benefits, such as adjusting the intestinal microbiome, boosting the immune system, and enhancing anti-inflammatory and anti-cancer activities. However, in recent years, some concerns have arisen about the consumption of probiotics, especially in vulnerable populations such as elderly, infants, and people with underlying diseases. As a result, finding a new alternative to probiotics that has the same function as probiotics and is safer has been prioritized. In recent years, postbiotics have been introduced as a great replacement for probiotics. However, the safety of these compounds is not exactly confirmed due to the limited in vivo research. In this review, the definition, classification, activities, limitations, and some advantages of postbiotics over probiotics are discussed. Finally, the limited published data about the safety of postbiotics is summarized.

Epilepsy is a persistent neurological condition that affects 60 million individuals globally, with recurrent spontaneous seizures affecting 80% of patients. Antiepileptic drugs (AEDs) are the main course of therapy for approximately 65% of epileptic patients, and the remaining 35% develop resistance to medication, which leads to Drug-Resistant Epilepsy (DRE). DRE continues to be an important challenge in clinical epileptology. There are several theories that attempt to explain the neurological causes of pharmacoresistance in epilepsy. The theory that has been studied the most is the transporter hypothesis. Therefore, it is believed that upregulation of multidrug efflux transporters at the blood-brain barrier (BBB), such as P-glycoprotein (P-gp), which extrudes AEDs from their target location, is the major cause, leading to pharmacoresistance in epilepsy. The most effective strategies for managing this DRE are peripheral and central inhibition of P-gp and maintaining an effective concentration of the drug in the brain parenchyma. Presently, no medicinal product that inhibits P-gp is being used in clinical practice. In this review, several innovative and promising treatment methods, including gene therapy, intracranial injections, Pgp inhibitors, nanocarriers, and precision medicine, are discussed. The primary goal of this work is to review the P-gp transporter, its substrates, and the latest novel treatment methods for the management of DRE.

More than two hundred million people around the world are infected with malaria, a blood-borne disease that poses a significant risk to human life. Single medications, such as lumefantrine, primaquine, and chloroquine, as well as combinations of these medications with artemisinin or its derivatives, are currently being used as therapies. In addition, due to rising antimalarial drug resistance, other therapeutic options are needed immediately. Furthermore, due to anti-malarial medication failures, a new drug is required. Medication discovery and development are costly and time-consuming. Many malaria treatments have been developed however, most treatments have low water solubility and bioavailability. They may also cause drug-resistant parasites, which would increase malaria cases and fatalities. Nanotechnology may offer a safer, more effective malaria therapy and control option. Nanoparticles' high loading capacity, concentrated drug delivery, biocompatibility, and low toxicity make them an attractive alternative to traditional therapy. Nanotechnology-based anti-malarial chemotherapeutic medications outperform conventional therapies in therapeutic benefits, safety, and cost. This improves patient treatment compliance. The limitations of malaria treatments and the importance of nanotechnological approaches to the treatment of malaria were also topics that were covered in this review. The most recent advancements in nanomaterials and the advantages they offer in terms of medication delivery are discussed in this article. The prospective therapy for malaria is also discussed. Additionally, the limitations of malaria therapies and the importance of nanotechnology-based approaches to the treatment of malaria were explored.

Introduction: The role of glutamate in the development of some brain pathological conditions, such as multiple sclerosis, has been well described. Levetiracetam (LEV), a new broad-spectrum antiseizure medicine, is widely used to control certain types of seizures.

Method: Apart from its anti-seizure activity, LEV exerts neuroprotection via anti-inflammatory, antioxidant, and antiapoptotic effects. The current study was designed to evaluate the protective potential of LEV against glutamate-induced injury in OLN-93 oligodendrocytes.

Method: At first, the potential negative impact of LEV on OLN-93 viability was evaluated. After that, the cells were concurrently treated with LEV (0-100 μM) and glutamate (8 mM) for 24 h. The viability, redox status, and the rate of apoptosis of OLN-93 cells were then assessed using 3-[4,5-dimethylthiazol- 2-yl]-2,5-diphenyl-2H-tetrazolium bromide (MTT), 2',7' dichlorodihydrofluorescein diacetate (H2DCFDA), 2-thiobarbituric acid reactive substances (TBARS) and annexin V/propidium iodide (PI) assays, respectively. Moreover, caspase-3 expression, as a marker of cell apoptosis, was evaluated by western blotting.

Results: LEV at 1-800 μM did not have any negative effect on cell survival. Treatment with LEV (50 and 100 μM) substantially enhanced the cell viability following glutamate insult. The cytoprotective activity of LEV (50 and 100 μM) against glutamate toxicity was accompanied by reduced Reactive Oxygen Species (ROS) accumulation and Malondialdehyde (MDA) level. Moreover, 100 μM of LEV inhibited apoptosis and decreased the expression level of cleaved caspase-3 following glutamate exposure.

Conclusion: Taken together, the results suggested that LEV has protective effects against glutamate-mediated cytotoxicity in OLN-93 cells. The oligoprotective action of LEV was shown to be exerted via inhibition of oxidative stress and cellular apoptosis.
