The role of mitochondrial DNA variants and dysfunction in the pathogenesis and progression of multiple sclerosis.

Multiple sclerosis (MS) is a chronic autoimmune disease that affects the central nervous system (CNS). The etiology of MS remains elusive, with a complex interplay of genetic and environmental factors contributing to its pathogenesis. Recent studies showed mitochondrial DNA (mtDNA) as a potential player in the development and progression of MS.

Evaluation of discrepancy between clot-based and chromogenic factor IX coagulation assays in non-severe hemophilia B patients and identification of the causing mutations.

Background: Hemophilia B, or Christmas disease, is a hemorrhagic inherited disorder. Previous studies have reported measurement discrepancies in factor VIII activity between clot-based and chromogenic assays in approximately one-third of patients with non-severe hemophilia A. However, similar discrepancies in hemophilia B have been less extensively studied.

Chemokines in neurodegenerative diseases.

Neurodegeneration and neuroinflammation disorders are mainly the result of the deposition of various proteins, such as α-synuclein, amyloid-β and prions, which lead to the initiation and activation of inflammatory responses. Different chemokines are involved in the infiltration and movement of inflammatory leukocytes into the central nervous system (CNS) that express chemokine receptors. Dysregulation of several members of chemokines has been shown in the CNS, cerebrospinal fluid and peripheral blood of patients who have neurodegenerative disorders.

Self-assembling peptide nanofibers and nanoceramics in a model of alveolar bone repair: Insights from in vivo experiments and clinical trial.

Introduction: Tooth extraction initiates a cascade of homeostatic and structural modifications within the periodontal tissues, culminating in alveolar ridge resorption. To prevent ridge resorption following extraction and facilitate successful placement of an implant-supported prosthesis, alveolar ridge preservation was performed.

Methods: In this study, the biocompatibility of a nanocomposite consisting of self-assembling peptide nanofibers (organic phase) and tri-calcium phosphate-nano hydroxyapatite (mineral phase), was evaluated in rabbits.

Investigating the resilience of kidneys in rats exposed to chronic partial sleep deprivation and circadian rhythm disruption as disruptive interventions.

Sleep is a vital biological function that significantly influences overall health. While sleep deprivation (SD) and circadian rhythm disruption are known to negatively impact various organs, their specific effects on kidney function remain understudied. This study aimed to investigate the impact of chronic partial sleep deprivation and circadian rhythm disruption on renal function in rats, providing insights into the relationship between sleep disturbances and kidney health.

TNF-α-Induced NF-κB Alter the Methylation Status of Some Stemness Genes in HT-29 Human Colon Cancer Cell.

Background: Acquisition of stem-like properties requires overcoming the epigenetic barrier of differentiation and re-expression of several genes involved in stemness and the cell cycle. DNA methylation is the classic epigenetic mechanism for de/differentiation. The writers and erasers of DNA methylation are not site-specific enzymes for altering specific gene methylation.

Do Exercise and Magnesium Sulfate Improve Infertility Caused by Lithium Carbonate in Male Rats?

Background: Lithium (Li) is widely used in the treatment of bipolar disorder, but it may lead to toxicity in the reproductive system. Considering the harmful effect of Li consumption on fertility and the positive effect of magnesium sulfate (MgSo) and moderate-intensity training (MIT) on improving the quality of men's sperm, the current research was conducted to determine the impact of MIT and MgSo on infertility caused by Li.

Materials And Methods: Seventy-two male rats were divided into 12 groups, control, Li10 mg/kg/day/ip, MgSo 80 mg/kg/day/ip; MIT; Li40 mg/kg/day/ip; Li10+MgSo; Li10+MIT; Li10+MgSo+MIT; Li40+MgSo; Li40+MIT; Li40+MgSo+MIT.

Understanding the complex function of gut microbiota: its impact on the pathogenesis of obesity and beyond: a comprehensive review.

Obesity is a multifactorial condition influenced by genetic, environmental, and microbiome-related factors. The gut microbiome plays a vital role in maintaining intestinal health, increasing mucus creation, helping the intestinal epithelium mend, and regulating short-chain fatty acid (SCFA) production. These tasks are vital for managing metabolism and maintaining energy balance.

Development of a hydrogel-based three-dimensional (3D) glioblastoma cell lines culture as a model system for CD73 inhibitor response study.

Background: Despite the development of various therapeutic approaches over the past decades, the treatment of glioblastoma multiforme (GBM) remains a major challenge. The extracellular adenosine-generating enzyme, CD73, is involved in the pathogenesis and progression of GBM, and targeting CD73 may represent a novel approach to treat this cancer. In this study, three-dimensional culture systems based on three hydrogel compositions were characterized and an optimal type was selected to simulate the GBM microenvironment.

Converging frontiers in cancer treatment: the role of nanomaterials, mesenchymal stem cells, and microbial agents-challenges and limitations.

Globally, people widely recognize cancer as one of the most lethal diseases due to its high mortality rates and lack of effective treatment options. Ongoing research into cancer therapies remains a critical area of inquiry, holding significant social relevance. Currently used treatment, such as chemotherapy, radiation, or surgery, often suffers from other problems like damaging side effects, inaccuracy, and the lack of ability to clear tumors.

Stimuli-responsive carrageenan-based biomaterials for biomedical applications.

These biomaterials exhibit a variety of beneficial properties, such as antiviral, antitumor, and immunomodulatory effects, which set them apart from other polysaccharides. Stimuli-responsive carrageenan-based biomaterials have attracted particular attention due to their unique properties, such as reducing systemic toxicity and controlling drug release.

Case report: Chronic inflammatory demyelinating polyradiculoneuropathy with severe central nervous system demyelination: a clinicopathological study.

Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an immune-mediated disease that mainly affects the peripheral nerves and nerve roots and typically presents with distal dominant motor and sensory disturbances as clinical symptoms. Central nervous system (CNS) demyelination with inflammation occurs infrequently in patients with CIDP. Here, we present a unique autopsy report of CIDP causing severe demyelination along the entire spinal cord.

Association of HPA Antigens with Immune Thrombocytopenia: A Case-Control Study by PCR-SSP Method.

Human platelet antigens (HPAs) play a clinically significant role in alloimmunization and the development of immune-mediated disorders such as immune thrombocytopenia (ITP), fetal and neonatal alloimmune thrombocytopenia (FNAIT), and post-transfusion purpura (PTP). Understanding the genetic profiles of HPAs is critical for preventing and treating these conditions. Given the limitations of serological methods in determining HPA genotypes, this study aims to investigate the association between the genotypes of HPA1, HPA2, HPA3, HPA4, and HPA15 antigens and autoimmune thrombocytopenia in Lorestan Province, utilizing the PCR-SSP method.
