    Exacerbated Cellular Senescence in Human Dopaminergic Neurons along with an Increase in LRRK2 Kinase Activity

    Dong Hwan Ho1,*, Minhyung Lee2,3, Daleum Nam1, Hyejung Kim1, Janghwan Kim2,3, Mi Kyoung Seo4,5, Sung Woo Park4,5, Ilhong Son1,6,*

    BIOCELL, Vol.49, No.7, pp. 1225-1244, 2025, DOI:10.32604/biocell.2025.065486 - 25 July 2025

    Abstract Background: Parkinson’s disease (PD) is a common neurodegenerative disease, characterized by symptoms like tremors, muscle rigidity, and slow movement. The main cause of these symptoms is the loss of dopamine-producing neurons in a brain area called the substantia nigra. Various genetic and environmental factors contribute to this neuronal loss. Once symptoms of PD begin, they worsen with age, which also impacts several critical cellular processes. Leucine-rich repeat kinase 2 (LRRK2) is a gene associated with PD. Certain mutations in LRRK2, such as G2019S, increase its activity, disrupting cellular mechanisms necessary for healthy neuron function, including… More >

    Abstract Background: Mesenchymal stem cells (MSCs) have shown great potential in treating neurodegenerative diseases, including Parkinson’s disease (PD), due to their ability to differentiate into neurons and secrete neurotrophic factors. Genetic modification of MSCs for PD treatment has become a research focus. Methods: In this study, rat pulmonary mesenchymal stem cells (PMSCs) were transduced with lentiviral vectors carrying Lmx1a/NeuroD1 to establish genetically engineered PMSCs (LN-PMSCs) and induce their differentiation into dopaminergic neurons. The LN-PMSCs were then transplanted into the right medial forebrain bundle region of PD model rats prepared using the 6-Hydroxydopamine (6-OHDA) method. Four weeks… More >

    Pioneering a new era in Parkinson’s disease management through adipose-derived mesenchymal stem cell therapy

    MOHAMMAD-SADEGH LOTFI, FATEMEH B. RASSOULI*

    BIOCELL, Vol.48, No.10, pp. 1419-1428, 2024, DOI:10.32604/biocell.2024.053597 - 02 October 2024

    Abstract Parkinson’s disease (PD) is one of the fastest-growing neurodegenerative disorders worldwide. So far, PD treatments only offer little clinical relief and cannot reverse or stop the disease progression. Stem cell (SC) therapy is a rapidly evolving technology that holds significant promise for enhancing current therapeutic approaches. Adipose-derived mesenchymal SCs (AD-MSCs) have many features such as easy harvest with minimal invasive techniques, high plasticity, non-immunogenicity, and no ethical issues, which have made them suitable choices for clinical applications in regenerative research. AD-MSCs are ideal tools to treat PD, as they have the potential to differentiate into… More >

    The Lightweight Edge-Side Fault Diagnosis Approach Based on Spiking Neural Network

    Jingting Mei, Yang Yang*, Zhipeng Gao, Lanlan Rui, Yijing Lin

    CMC-Computers, Materials & Continua, Vol.79, No.3, pp. 4883-4904, 2024, DOI:10.32604/cmc.2024.051860 - 20 June 2024

    Abstract Network fault diagnosis methods play a vital role in maintaining network service quality and enhancing user experience as an integral component of intelligent network management. Considering the unique characteristics of edge networks, such as limited resources, complex network faults, and the need for high real-time performance, enhancing and optimizing existing network fault diagnosis methods is necessary. Therefore, this paper proposes the lightweight edge-side fault diagnosis approach based on a spiking neural network (LSNN). Firstly, we use the Izhikevich neurons model to replace the Leaky Integrate and Fire (LIF) neurons model in the LSNN model. Izhikevich… More >

    Exercise and exerkine upregulation: Brain-derived neurotrophic factor as a potential non-pharmacological therapeutic strategy for Parkinson’s disease

    VIRAAJ VISHNU PRASAD, JENNIFER SALLY SAMSON, VENKATACHALAM DEEPA PARVATHI*

    BIOCELL, Vol.48, No.5, pp. 693-706, 2024, DOI:10.32604/biocell.2024.048776 - 06 May 2024

    Abstract Physical activity and exercise have several beneficial roles in enhancing both physiological and psychological well-being of an individual. In addition to aiding the regulation of aerobic and anaerobic metabolism, exercise can stimulate the synthesis of exerkine hormones in the circulatory system. Among several exerkines that have been investigated for their therapeutic potential, Brain-derived neurotrophic factor (BDNF) is considered the most promising candidate, especially in the management of neurodegenerative diseases. Owing to the ability of physical activity to enhance BDNF synthesis, several experimental studies conducted so far have validated this hypothesis and produced satisfactory results at More > Graphic Abstract

    Muhammad Umar Nasir1, Omar Kassem Khalil2, Karamath Ateeq3, Bassam SaleemAllah Almogadwy4, M. A. Khan5, Khan Muhammad Adnan6,*

    CMC-Computers, Materials & Continua, Vol.79, No.1, pp. 963-981, 2024, DOI:10.32604/cmc.2024.047874 - 25 April 2024

    Abstract Cervical cancer is an intrusive cancer that imitates various women around the world. Cervical cancer ranks in the fourth position because of the leading death cause in its premature stages. The cervix which is the lower end of the vagina that connects the uterus and vagina forms a cancerous tumor very slowly. This pre-mature cancerous tumor in the cervix is deadly if it cannot be detected in the early stages. So, in this delineated study, the proposed approach uses federated machine learning with numerous machine learning solvers for the prediction of cervical cancer to train… More >

    Abstract The aim of this study was to find a way to efficiently separate neuronal cells from the cerebral cortex of adult rats, providing a reference method for rapid acquisition of neuronal cells from the adult rat brain. Fifteen SD rats were randomly divided into three groups, with five SD rats in each group. Then, neuron cells were isolated from the adult rat cerebral cortex by the grinding method, the trypsin method, and the collagenase II method, respectively. The expression of anti-NeuN in the neurons of each group was analyzed by flow cytometry. The acquisition rates More >

    Modeling the Spike Response for Adaptive Fuzzy Spiking Neurons with Application to a Fuzzy XOR

    A. M. E. Ramírez-Mendoza1

    CMES-Computer Modeling in Engineering & Sciences, Vol.115, No.3, pp. 295-311, 2018, DOI:10.3970/cmes.2018.00239

    Abstract A spike response model (SRM) based on the spikes generator circuit (SGC) of adaptive fuzzy spiking neurons (AFSNs) is developed. The SRM is simulated in MatlabTM environment. The proposed model is applied to a configuration of a fuzzy exclusive or (fuzzy XOR) operator, as an illustrative example. A description of the comparison of AFSNs with other similar methods is given. The novel method of the AFSNs is used to determine the value of the weights or parameters of the fuzzy XOR, first with dynamic weights or self-tuning parameters that adapt continuously, then with fixed weights More >

    Differentiation into neurons of rat bone marrow-derived mesenchymal stem cells

    Ming Guan1, Yaping Xu2, Wei Wang3, Shan Lin2

    European Cytokine Network, Vol.25, No.3, pp. 58-63, 2014, DOI:10.1684/ecn.2014.0357

    Abstract Purpose:It has been reported that mesenchymal stem cells (MSCs) can differentiate into neurons as an effect of adding extraneous factors, such as β-mercaptoethanol, dimethyl sulfoxide and butylated hydroxyanisole. However, many of these compounds could harm MSCs and the human body, which restricts their application. We examined whether MSCs could differentiate into neuron-like cells under the influence of natural growth factors, such as epidermal growth factor (EGF), basic fibroblast growth factor (bFGF), insulin-like growth factor 1 (IGF-1, and neurotrophin 3 (NT-3). Methods: MSCs were collected from rat bone marrow using the plastic adherent selection method, and… More >

    BIOCELL, Vol.37, No.2, pp. 37-43, 2013, DOI:10.32604/biocell.2013.37.037

    Abstract Creatine is widely used by athletes as an ergogenic resource. The aim of this study was to evaluate the influence of creatine supplementation on the duodenum of rats submitted to physical training. The number and myenteric neuronal cell bodies as well mucosal and muscular tunic morphometry were evaluated. Control animals received a standard chow for 8 weeks, and the treated ones received the standard chow for 4 weeks and were later fed with the same chow but added with 2% creatine. Animals were divided in groups: sedentary, sedentary supplemented with creatine, trained and trained supplemented… More >
