Special Issue Information

Dear Colleagues,

We are pleased to announce an upcoming Special Issue of Applied Sciences focusing on naturally sourced treatments used as a therapeutic alternative for neurological diseases, from preclinical to clinical settings. Neurological disorders represent the leading cause of disability and the second leading cause of death worldwide. According to the WHO predictions, it is estimated that by 2040, neurological diseases will surpass cancer and become the second leading cause of death worldwide. However, the development of therapies represents a major challenge, as do new pharmacological and therapeutic targets to slow their progression. On the other hand, the search for effective neuroprotective strategies has generated great interest and is focused on plant metabolites such as flavonoids, alkaloids, polyphenols, among others, which have shown different antioxidant, protective, and anti-inflammatory effects, as they combat oxidative stress, a key factor in neurodegenerative diseases. Oxidative stress results from an imbalance between free radicals and antioxidants in the body, causing neuronal damage and the progression of diseases such as Alzheimer's, Parkinson's, amyotrophic lateral sclerosis (ALS), epilepsy, multiple sclerosis, fibromyalgia, among others.

Our goal in launching this Special Issue is to provide an overview of the latest findings in preclinical and clinical studies using plant extracts and secondary metabolites, in order to evaluate the efficacy of these treatments and enable researchers to identify the effect of potential therapeutic agents on these diseases. In addition, medical and scientific contributors will also provide translational perspectives on how these preclinical and clinical research results can advance the treatment of these diseases. This compilation of original research and reviews will provide readers with a comprehensive overview of advances in preclinical and clinical research for the treatment and/or pharmacological management of these diseases.

The specific approaches are as follows:

  • Studies of neurological diseases focused on animal models that use plant metabolites or phytopharmaceuticals as an alternative treatment for these diseases.
  • Clinical studies demonstrating the efficacy of natural treatments for neurological diseases.
  • Isolation and characterization of secondary plant metabolites with potential use in the treatment of neurological diseases.
  • Innovative in vitro and in vivo studies focused on the treatment of neurological diseases using natural products.

We welcome original research articles, systematic reviews, preclinical and clinical trials.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Introduction: Spontaneous and recurrent epileptic seizures cause neuroinflammation, whereas the chronic administration of antiepileptic drugs may lead to hepatotoxicity and nephrotoxicity. Investigating natural compounds such as naringenin, which exhibits antioxidant, anti-inflammatory, and neuroprotective properties, could mitigate these toxic effects. However, whether naringenin delays seizure onset through anti-inflammatory mechanisms remains unclear. Objective: We evaluated the anticonvulsant effect of subchronic naringenin administration and its impact on inflammatory biomarkers in rats. Methods: Thirty-two male Wistar rats were divided into four groups (n = 8 each): vehicle (10% DMSO), naringenin (50 mg/kg), naringenin (100 mg/kg), and diazepam (4 mg/kg). Treatments were administered once daily for ten days through the intraperitoneal route. On day 11, status epilepticus (SE) was induced via the lithium-pilocarpine model. One hour after SE onset, cardiac blood was collected, and the serum was analyzed via ELISA to quantify the following inflammatory markers: superoxide dismutase (SOD), C-reactive protein (CRP), carbonyl protein, and nitrite/nitrate. Results: We found that 100 mg/kg naringenin increased the latency to SE and the first generalized seizure and shortened the duration of generalized seizures. Fifty percent of the rats in the 100 mg/kg naringenin group did not develop SE. The group treated with 100 mg/kg naringenin demonstrated reduced levels of CRP, protein carbonyls, and nitrates; conversely, the inhibition of SOD activity increased. Conclusions: Naringenin exerted anticonvulsant activity associated with a reduction in oxidative stress and inflammatory plasma biomarkers, suggesting its potential utility in the future development of alternative treatments to reduce epilepsy symptoms.
