Vincamine exerts hepato-protective activity during colon ligation puncture-induced sepsis by modulating oxidative stress, apoptosis, and TNFα/Nrf-2/Keap-1 signaling pathways

Sepsis is a pathological and biochemical disorder induced by numerous infections, leading to critical illness and a high mortality rate worldwide. Vincamine is an indole alkaloid compound obtained from the leaves of Vinca minor. The present study aims to investigate the hepato-protective activity of vincamine during colon ligation puncture (CLP)-induced sepsis at the molecular level. Sepsis was induced using the CLP model. Liver function enzymes such as ALT and AST were analyzed. The hepatic antioxidant status (SOD and GSH), lipid peroxidation (MDA), the pro-inflammatory cytokines (TNFα, IL-6, and IL-1β), bax, bcl2, and cleaved caspase 3 proteins were estimated. Nrf-2 and Keap-1 protein expression was evaluated using western blotting. Histopathological investigation of liver tissues was also performed. CLP-induced sepsis led to liver injury through the elevation of ALT and AST liver enzymes. Oxidative stress was initiated during CLP via the suppression of hepatic GSH content and SOD activity and the elevation of MDA. The inflammatory condition was activated by the upregulation of TNFα, IL-6, IL-1β, and Keap-1 and the downregulation of Nrf-2 proteins. The apoptosis was initiated through the activation of bax and cleaved caspase 3 protein expression and inhibition of bcl2 protein expression. However, vincamine significantly improved the hepatic histological abnormalities and decreased liver enzymes (ALT and AST). It ameliorated oxidative stress, as evidenced by reducing the hepatic MDA content and increasing the SOD activity and GSH content. Moreover, vincamine reduced the hepatic content of TNFα, IL-6, IL-1β, and Keap-1 and increased Nrf-2 protein expression. Additionally, it upregulated bcl2 protein expression and downregulated bax and cleaved caspase 3 protein expression. Vincamine exhibited hepato-protective potential during CLP-induced sepsis via the cross-connection of antioxidant, anti-inflammatory, and anti-apoptotic activities by modulating TNFα/IL-6/IL-1β/Nrf-2/Keap-1 and regulating bax/bcl2/cleaved caspase 3 signaling pathways.

Position and frequency of lateral canals in carnassial teeth of dogs

Carnassial teeth, as one of the most important teeth in dogs, are commonly affected by different types of injuries and pathological disorders, which require endodontic treatment. Lateral canals, which leave the main root canal, and apical deltas are present in the root canal system of dogs. These canals represent small branches that leave the main root canal at a sharp angle and terminate in a region of the periodontal ligament on the external root surface. In this study, 200 teeth were included, of which 100 were superior fourth premolars and 100 were inferior first molars. Lateral canals were present in a total of 30 roots of superior fourth premolar teeth, whereas in inferior first molars, these canals were found in 3% of roots. In superior fourth premolars, lateral canals were mostly present in the apical third, 86%, while 14% were present in the middle third of the root. In inferior first molars, lateral canals were found in 3% of the roots, 2% in the apical third and 1% in the middle third of the roots. The knowledge of the complex root canal morphology is essential for any endodontic treatment. Due to the presence and frequency of lateral canals, it is imperative to perform more thorough cleaning and instrumentation while performing endodontic treatment on superior fourth premolars compared to inferior first molars.

Clinicopathological Aspects of Dilation and Curettage (D&C) Biopsies Taken from Patients Living at High Altitude in Taif, KSA, with a Special Emphasis on Chronic Endometritis.

Chronic endometritis (CE) is a persistent inflammation of the uterine lining. Although it has a minimal clinical presentation, CE adversely affects the reproductive ability of women. The aims of this study were to detect pathological endometrial patterns in D&C biopsies and to evaluate chronic endometritis in patients living in a high-altitude area (1800 m above sea level) in order to determine the clinical pathological features and prevalence. A cross-sectional study conducted at King Faisal Maternity Hospital included 100 samples of D&C biopsies from women complaining of various gynecological symptoms not due to gestational causes. The biopsies underwent tissue processing, H&E staining, and CD138 detection. Blood samples were taken for serological detection of infectious diseases, complete blood count, and chemical parameters. The mean age of women in the study with CE was 48.5 ± 8.5 years, and that of those without CE was 46.9 ± 9.7 years. The most common complaints were abnormal uterine bleeding, accounting for 83%. CE was present in 8% of cases, and there was a nonsignificant difference in hematological parameters between women with CE and those with other pathological diagnoses. There were also nonsignificant differences in chemical parameters, except for FSH and LH levels, which showed a significant difference, with p-values of 0.05 and 0.02, respectively. It can be concluded that the most common gynecological complaint of women in this study was abnormal uterine bleeding. The most commonly diagnosed pathological endometrial disorder in D&C biopsies was disordered proliferative endometrium, followed by endometrial polyps and endometrial hyperplasia. All of these are usually associated with hormonal disturbance, which appeared to be very common in the women in this study. The prevalence of chronic endometritis detected in our study was 8%, which is relatively high.

The Role of Epigenetic Mechanisms in the Pathogenesis of Hepatitis C Infection.

Hepatitis C virus (HCV) is a hepatotropic virus that can be transmitted through unsafe medical procedures, such as injections, transfusions, and dental treatment. The infection may be self-limiting or manifest as a chronic form that induces liver fibrosis, cirrhosis, or progression into hepatocellular carcinoma (HCC). Epigenetic mechanisms are major regulators of gene expression. These mechanisms involve DNA methylation, histone modifications, and the activity of non-coding RNAs, which can enhance or suppress gene expression. Abnormal activity or the dysregulated expression of epigenetic molecules plays an important role in the pathogenesis of various pathological disorders, including inflammatory diseases and malignancies. In this review, we summarise the current evidence on epigenetic mechanisms involved in HCV infection and progression to HCC.

CKD-497 inhibits NF-kB signaling and ameliorates inflammation and pulmonary fibrosis in ovalbumin-induced asthma and particulate matter-induced airway inflammatory diseases.

Introduction: Air pollution, allergens, and bacterial infections are major contributors to pathological respiratory disorders worldwide. CKD-497, derived from the rhizome of Atractylodes japonica and the fruits of Schisandra chinensis, is known for its ability to relieve cough and facilitate phlegm expectoration. However, its protective action against allergic asthma and fine dust-induced lung inflammation, along with its underlying mechanisms, have not been thoroughly investigated. Methods: In this study, we established mouse models of ovalbumin (OVA)-induced asthma and particulate matter (PM)-induced pulmonary inflammation to evaluate the effects of CKD-497. Mice were administered CKD-497 orally, and various parameters such as airway inflammation, mucus production, and proinflammatory cytokine levels (IL-1β, IL-6, TNF-α) were measured. Additionally, the macrophage cell line RAW264.7 was pretreated with CKD-497 and stimulated with lipopolysaccharide (LPS) to assess inflammation via the NF-kB signaling pathway. Results: Oral administration of CKD-497 effectively attenuated airway inflammation and mucus production in both OVA-induced asthma and PM-induced lung inflammation models. It also significantly decreased the production of proinflammatory cytokines IL-1β, IL-6, and TNF-α. CKD-497 alleviated leukocyte infiltration, including neutrophils, and reduced fibrillary collagen deposition in PM10-treated mice. In vitro, CKD-497 pretreatment inhibited LPS-induced inflammation in RAW264.7 cells through the suppression of the NF-kB signaling pathway. Discussion: CKD-497 shows potent anti-inflammatory effects in mouse models of asthma and PM-induced lung inflammation, potentially mediated by the inhibition of the NF-kB pathway. These findings suggest that CKD-497 could serve as a functional supplement to protect against respiratory diseases by mitigating pulmonary and airway inflammation induced by allergens and air pollution.

Investigation of Anti-inflammatory, Antipyretic and Analgesic Activities of Citrullus colocynthis in Albino Rats through in vivo and Pharmacoinformatics Studies.

Hyperpyrexia, algesia and inflammation are pathological disorders which are treated with synthetic as well as herbal medications. The basic aim of the present study is to evaluate the ethnopharmacological activities of phytoconstituents that are present in C. colocynthis (fruit extract) by using in vivo and in silico studies. Thirty-six albino rats were used in our studies with an average weight between 150-170 g. Anti-inflammatory activity was investigated using carrageenan (an extract from a red seaweed) that induced edema in albino rat paws. However, in antipyretic and analgesic activity studies, yeast and acetic acid were used to cause pyrexia or algesia, respectively. Different doses of acetone fruit extract were used to treat inflammation, pyrexia and algesia. Our results showed that the maximum percentage inhibition of acetonic fruit extract in anti-inflammatory and analgesic activities was observed at 70% and 100%, respectively, with 400 mg/kg doses, and in pyretic activity the maximum inhibitory percentage was 86% with a 100 mg/kg dose. In in silico analysis, we have shown that bioactive compounds (α-spinasterol, ascorbic acid and chlorogenic acid) found in fruit extract have outstanding inhibition properties that involves proteins PTGS2, TLR2 and TRPV4. C. colocynthis fruit extract shows results that are statistically significant (p < 0.005) and comparable to a reference drug. Acetonic fruit extract of C. colocynthis can be used as a natural and safe remedy with no side effects. Both in vivo and in silico studies on chlorogenic acid, ascorbic acid and α-spinasterol have shown that these are inhibitory compounds that can be used for boosting the immune response.

Neuroprotective Effect of Famotidine in Mouse Models of Alzheimer's Disease.

Famotidine is a competitive histamine H-receptor antagonist that reduces the formation of stomach acid and is used to treat gastrointestinal disorders associated with acid reflux, gastroesophageal reflux disease, duodenal ulcer, gastric ulcer, and pathological hypersecretory disorders. This study is designed to investigate the possible neuroprotective effects of the ranolazine scopolamine-induced Alzheimer's disease-like feature in a mouse model. Mice were divided equally into five groups (ten mice per group), including control group and induction group. The mice in the induction group were administered scopolamine 1 mg/kg i.p., once daily for 7 days, to induce features similar to Alzheimer's disease. The mice in the remaining three treatment groups were given tested medications prophylactically for 14 days. After that the induction was carried out with scopolamine 1 mg/kg i.p., once daily, while the tested medication dosages were continued for an additional 7 days. These treatment groups included: the donepezil group (5 mg/kg/day), the famotidine group (40 mg/kg/day) and the combined group with donepezil (5 mg/kg/day) and famotidine (40 mg/kg/day); all were administrated i.p., once daily. Behavioral parameters were assessed, among others with the Y-maze test and novel object recognition test, and the inflammatory cytokines and oxidative stress parameters were assessed as well. Famotidine exhibits significant improvements in behavior and memory, level of oxidative stress parame-ter, and inflammatory cytokines. Famotidine and its combination at prescribed doses in the current study improved learning and memory impairments in mice model of Alzheimer's disease probably via their antioxidant and anti-inflammatory properties confirmed by a significant increase in antioxidant mediator and a significant decrease in oxidative stress marker and inflammatory cytokines.

The role of HDAC3 in inflammation: mechanisms and therapeutic implications.

Histone deacetylases (HDACs) are critical regulators of inflammatory gene expression, and the efficacy of pan-HDAC inhibitors has been implicated in various disease conditions. However, it remains largely unclear how HDACs precisely regulate inflammation. To this end, evaluating the isoform-specific function of HDACs is critical, and the isoform-specific targeting could also circumvent the off-target effects of pan-HDAC inhibitors. This review provides an overview of the roles of HDAC3, a class I HDAC isoform, in modulating inflammatory responses and discusses the molecular mechanisms by which HDAC3 regulates inflammation associated with brain pathology, arthritis, cardiovascular diseases, lung pathology, allergic conditions, and kidney disorders. The articles also identify knowledge gaps in the field for future studies. Despite some conflicting reports, the selective inhibition of HDAC3 has been demonstrated to play a beneficial role in various inflammatory pathologies. Exploring the potential of HDAC3 inhibition to improve disease prognosis is a promising avenue requiring further investigation.

Neurocognitive features in childhood & adulthood in autism spectrum disorder: A neurodiversity approach.

Autism spectrum disorder (ASD) is a neurodevelopmental disorder with a diverse profile of cognitive functions. Heterogeneity is observed among both baseline and comorbid features concerning the diversity of neuropathology in autism. Symptoms vary depending on the developmental stage, level of severity, or comorbidity with other medical or psychiatric diagnoses such as intellectual disability, epilepsy, and anxiety disorders. The neurodiversity movement does not face variations in neurological and cognitive development in ASD as deficits but as normal non-pathological human variations. Thus, ASD is not identified as a neurocognitive pathological disorder that deviates from the typical, but as a neuro-individuality, a normal manifestation of a neurobiological variation within the population. In this light, neurodiversity is described as equivalent to any other human variation, such as ethnicity, gender, or sexual orientation. This review will provide insights about the neurodiversity approach in children and adults with ASD. Using a neurodiversity approach can be helpful when working with children who have autism spectrum disorder (ASD). This method acknowledges and values the various ways that people with ASD interact with one another and experience the world in order to embrace the neurodiversity approach when working with children with ASD.

Meldonium Supplementation in Professional Athletes: Career Destroyer or Lifesaver?

Meldonium is a substance with known anti-anginal effects demonstrated by numerous studies and human clinical trials; however, it does not possess marketing authorization within the European Union, only in ex-Soviet republics. Since 2016, meldonium has been included by the World Anti-doping Agency (WADA) on the S4 list of metabolic modulators. In performance athletes, meldonium is now considered a doping agent due to its capacity to decrease lactate production during and after exercise, its capability to enhance the storage and utilization of glycogen, and its protective action against oxidative stress. Together, these attributes can significantly improve aerobic endurance, cardiac function, and capacityas well as shorten recovery times (allowing higher intensity training), thereby enhancing performance. The purpose of this review is to highlight the most important mechanisms underlying the protective effect of meldonium against mitochondrial dysfunction (MD), which is responsible for oxidative stress, inflammation, and the cardiac changes known as "athletic heart syndrome."Meldonium acts as an inhibitor of γ-butyrobetaine hydroxylase (BBOX), preventing the de novo synthesis of carnitine and its absorption at the intestinal level via the organic cation/carnitine transporter 2 (OCTN2) and directing the oxidation of fatty acids to the peroxisomes. The decrease in mitochondrial β-oxidation of fatty acids leads to a reduction in lipid peroxidation products that cause oxidative stress and prevent the formation of acyl/acetyl-carnitines involved in numerous pathological disorders. Given the recent findings of the potentially detrimental effects of prolonged high-intensity exercise on cardiovascular health and coronary atherosclerosis, there may be legitimate arguments for the justification of the use of substances likemeldonium as protective supplements for athletes.

Structural characterization of sphingomyelins from tissue using electron-induced dissociation.

Sphingomyelins (SMs) and resulting metabolic products serve important functional and cell signaling roles and can act as potential biomarkers and therapeutic targets in many pathological disorders. SMs each contain a sphingoid base, an amide-linked fatty acyl chain, and a phosphocholine headgroup. Despite these simple building blocks, variations and modifications of both the sphingoid base and the fatty acyl chain result in a diverse array of structurally complicated SM compounds. Conventional tandem mass spectrometry (MS/MS) using the collision-induced dissociation (CID) method only provides limited structural information, necessitating other tools to unravel the structural complexity of these lipids. We utilize electron-induced dissociation (EID) and sequential CID/EID approaches to elucidate detailed structural features of SMs. Integrating the CID/EID method into an imaging MS workflow enables accurate identification of SMs directly from kidney tissue. The application of EID enables identification of SMs at the molecular species level, identifying the sphingosine base and the amide-linked fatty acyl chains. Furthermore, removal of the phosphocholine headgroup via CID followed by sequential EID in an MS3 analysis (CID/EID) enhances the structural information obtained. CID/EID provides diagnostic fragmentation patterns revealing the hydroxylation site and double bond position in both the sphingosine base and amide-linked fatty acyl chains. Detailed structural information of SMs from synthetic standards and biological tissue samples is obtained using an alternative electron-based dissociation method. Accurate characterization of SMs promises to better inform studies of tissue biochemistry, lipid metabolism, and molecular pathology.

In Silico Electrophysiological Investigation of Transient Receptor Potential Melastatin-4 Ion Channel Biophysics to Study Detrusor Overactivity.

Enhanced electrical activity in detrusor smooth muscle (DSM) cells is a key factor in detrusor overactivity which causes overactive bladder pathological disorders. Transient receptor potential melastatin-4 (TRPM4) channels, which are calcium-activated cation channels, play a role in regulating DSM electrical activities. These channels likely contribute to depolarizing the DSM cell membrane, leading to bladder overactivity. Our research focuses on understanding TRPM4 channel function in the DSM cells of mice, using computational modeling. We aimed to create a detailed computational model of the TRPM4 channel based on existing electrophysiological data. We employed a modified Hodgkin-Huxley model with an incorporated TRP-like current to simulate action potential firing in response to current and synaptic stimulus inputs. Validation against experimental data showed close agreement with our simulations. Our model is the first to analyze the TRPM4 channel's role in DSM electrical activity, potentially revealing insights into bladder overactivity. In conclusion, TRPM4 channels are pivotal in regulating human DSM function, and TRPM4 channel inhibitors could be promising targets for treating overactive bladder.

Extreme Psycho-Emotional Stress for Kharkivites Caused by Russia-Aggressor Bombardments: Ways to Overcome

Background: This psychological research, conducted in the first months of the war, was carried out for the first time in world scientific practice. Our aim was to present the missing mathematical-statistical assessment of the emotional response and psycho-physiological state of civilians who, from the first day of the war, were in Kharkiv, constantly under Russian-aggressor fire. Methods: 585 Kharkiv participants were tested using the only possible means accepted during constant rocket attacks and hostilities (visual psychodiagnostics methods). Results: Negative mental manifestations and the disability of Kharkivites to manage their psycho-emotional state have been established. Their evolution has been traced. The time stages of the participants’ states were identified and characterized. Nearly all participants demonstrated intense stress-induced arousal and psycho-emotional incapacity/inability. Psychotrauma also developed among Kharkivites, who constantly monitored military events through social Internet networks. Children were the most susceptible to all severe sensations. Conclusions: The identified conditions are dangerous because they lead to pathological neurological-somatic disorders, psycho-emotional incapacity, or disability due to the stress-induced somatic-physiological destruction of the body. To normalize the psycho-emotional self-awareness and to help the participants get out of a stressful state, various preventive-rehabilitation means were used.

IDENTIFICATION OF SIGNIFICANT TEMPORAL FEATURES FROM PHOTO PULSE PLETHYSMOGRAM FOR PREDICTION OF HYPERGLYCEMIA

The increase in diabetic class population is witnessed every year and hence frequent need of checking blood glucose levels is highly required in both diabetic and healthy subjects. This requirement has led many researchers to develop efficient, accurate and easy estimation of blood glucose level without painful blood pricking or extraction. In line with this objective, this study is an effort for waveform analysis of autonomic response of photo pulse plethysmogram (PPG) and to evaluate PPG features that may provide better non-invasive detection of the disease. A total of 300 (150 diabetic and 150 control) subjects aged more than 18 years are considered for this study. Relevant patient details were obtained, and finger PPG recording in digital form was performed for 5 min with the digitization sampling rate of 200 sample points per second. After signal baseline correction, features are calculated from averaged normalized PPG and its first and second derivatives. A total of 41 features were derived from normalized PPG pulse and its derivatives for the assessment of hyperglycemia. But in practice, computation of many features is time-consuming and truly a tedious job for any model design. Further, model performance and accuracy are affected significantly. Applying six different statistical and machine learning methods for the identification of important features, 20 features were identified out of 41 features whose values are highly significantly different for control and study (diabetic) groups. This work was focused on feature extraction stage for a PPG-based diagnostic system. Though our study is aimed to identify significant features that can discriminate between diabetic and control groups non-invasively, these features have the potential for much clinical assessment and other pathological disorders without any doubt.

Background: With increasing bacterial resistance for antibiotic, there is an increasing interest in medicinal herbal as a new source of an antimicrobial agents and with less side effects than conventional drugs. Objective: Was to evaluate the potential of Syzygium aromaticum and rosemarinus officinalis extract on Proteus mirabilis isolates in vitro. Methods: Six pathogenic gram negative bacilli belonging to three different genus (E.coli, Proteus mirabilis, and Enterobacter aerogenes) and two isolates from each species were used in this study and four concentration (100%, 75%, 50%, 25% mg/ml ) from each plant extracts (aqueous and ethanolic of Syzygium aromaticum and rosemarinus officinalis extracts ) were prepared to be antibacterial agent. antibacterial activity was measured by using wells method and five antibiotics using to compare with the activity of antibacterial agent. Results: The result of the study shown that the ethanolic extracts of Syzygium aromaticum is a strong antibacterial agent (with diameter of inhibition zone 25 mm) against Proteus mirabilis. Enterobacter aerogenes with (15mm) of inhibition zon, E.coli did not show any inhibition zone also the aqueous and ethanolic of rosemarinus officinalis extracts and aqueous of Syzygium aromaticum extracts did not show any activity towards any gram negative bacilli also the results of the study show resistance isolates of E.coli and Proteus mirabilis toward several antibiotic while Enterobacter aerogenes is sensitive for more antibiotics that used in this study. Conclusions: Our study concluded that the extract of Syzygium aromaticum has high potential as antibacterial agent against UTI that caused by Proteus mirabilis, clove (syzygium aromaticum) can be used in pharmaceutical for the production of new synthetic agents. There is an increasing interest in phytochemicals as new sources of natural antioxidant and antimicrobial agents. The natural compounds which have biological activities are interest to pharmaceutical industries especially for treatment of human disease of microbial origin and several pathological disorders such as cancergenesis, coronary atherosclerosis, as well as in ageing processes.

A Visual Approach for Inducing Dolichoectasia in Mice to Model Large Vessel-Mediated Cerebrovascular Dysfunction.

The blood-brain (BBB) is a crucial system that regulates selective brain circulation with the periphery, as an example, allowing necessary nutrients to enter and expel excessive amino acids or toxins from the brain. To model how the BBB can be compromised in diseases like vascular dementia (VaD) or Alzheimer's disease (AD), researchers developed novel methods to model vessel dilatation. A compromised BBB in these disease states can be detrimental and result in the dysregulation of the BBB leading to untoward and pathological consequences impacting brain function. We were able to modify an existing technique that enabled us to inject directly into the Cisterna magna (CM) to induce dilatation of blood vessels using elastase, and disrupt the tight junctions (TJ) of the BBB. With this method, we were able to see various metrics of success over previous techniques, including consistent blood vessel dilatation, reduced mortality or improved recovery, and improving the fill/opacifying agent, a silicone rubber compound, delivery for labeling blood vessels for dilatation analysis. This modified minimally invasive method has had promising results, with a 19%-32% increase in sustained dilatation of large blood vessels in mice from 2 weeks to 3 months post-injection. This improvement contrasts with previous studies, which showed increased dilatation only at the 2 week mark. Additional data suggests sustained expansion even after 9.5 months. This increase was confirmed by comparing the diameter of blood vessels of the elastase and the vehicle-injected group. Overall, this technique is valuable for studying pathological disorders that affect the central nervous system (CNS) using animal models.

Pharmacological and therapeutic potential of ginger in the management of neurodegenerative disorders

Secondary metabolites in ginger include 6-gingerol, 6-shogaol, 10-gingerol, gingerdiones, gingerdiols, paradols, 6-dehydrogingerols, 5-acetoxy-6- gingerol, 3,5-diacetoxy-6-gingerdiol, and 12-gingerol, all of which account for ginger's well-known pharmacological actions. Six-shogaol and six-gingerol are two of the most important active ingredients. There is experimental evidence to back ginger's medicinal properties, such as its antioxidant and anti-inflammatory activities. In contrast, ginger's purported neuroprotective advantage is a niche bioactivity with limited study. Increasing oxidative stress, neuroinflammation, and protein misfolding are common neuropathological characteristics of neurodegenerative disorders (NDs), which have become more common as life expectancy has increased. Ginger may be a potential for treating NDs because its phytochemicals target distinct ligand sites, as shown by their structure-activity relationships. Bioactive substances found there may help relieve neurological problems and pathological disorders by affecting markers which express apoptosis or sustenance. The cognitive-enhancing properties of ginger may be explained by its effects on the monoamine and cholinergic systems in various brain areas. In addition, ginger reduces the generation of inflammatory associated components. The current review intends to describe the impacts of ginger in the management of significant neurological conditions such as Alzheimer's disease, Parkinson's disease, and multiple sclerosis.

Oxidative stress and neurological disorders: Therapeutic strategies and pharmacological intervention

Oxidative stress plays a significant role in cerebral biochemical dysfunction, contributing to the increased sensitivity of the central nervous system to reactive oxygen species (ROS)-mediated injury. It is characterized by an imbalance between the production of ROS and the antioxidant capacity of the cell, which results in a variety of pathological disorders and diseases, including neurological conditions such as Parkinson&amp;rsquo;s disease, Alzheimer&amp;rsquo;s disease, schizophrenia, bipolar disorder, and anxiety. In this review, we delve into the role of oxidative stress in neurodegenerative disorders. We conducted a comprehensive search across various databases, including Google Scholar, ScienceDirect, and PubMed, with a focus on literature published within the past decade. Our search utilized terms such as &amp;ldquo;oxidative stress and neurological disorders,&amp;rdquo; &amp;ldquo;pharmacological interventions for neurological disorders,&amp;rdquo; &amp;ldquo;oxidative stress, free radicals, and neurological disorders,&amp;rdquo; and &amp;ldquo;free radicals and neurological disorders. Our aim was to elucidate the relationship between oxidative stress and neurological disorders, as well as to summarize available therapies and pharmacological interventions for these conditions.

A retrospective study of the relationship between the presence of complaints and the identified pathological changes in the temporomandibular joint

Introduction. In the practice of an orthodontist, diseases of the temporomandibular joint (TMJ) are an urgent problem due to their widespread, diverse clinical manifestations.Goal. To study the relationship between the identified anatomical and functional disorders of the TMJ, as risk factors for complications during orthodontic treatment, and the presence of characteristic complaints in the structure of pathological changes in the TMJ.Materials and methods. According to the type of organization and the ratio of data collection time, the scientific study belonged to a longitudinal retrospective study, according to the type of observation: case-control. A retrospective analysis of 102 outpatient medical records of patients who sought medical help from an orthodontist at a dental clinic was carried out. The criterion for inclusion in the study was the presence of a newly diagnosed disease of the temporomandibular joint, mandatory radiological diagnostic methods. Magnetic resonance imaging (MRI) of the TMJ in the patient who sought medical help was used as a radiation diagnosis. As part of the scientific study, the structure of pathological changes in the TMJ was analyzed, the relationship between the presence of complaints and the revealed pathology was studied.Results. The analysis of the data showed that the MR examination of the TMJ reveals pathological changes in patients who sought orthodontic care, both with complaints and with an asymptomatic course of diseases. Data analysis did not show a statistically significant relationship between the presence of complaints and the revealed pathology in the case of degenerative (χ2 = 0.123; p &gt; 0.05), inflammatory changes in the TMJ (χ2 = 0.123; p &gt; 0.05) and pathological disorders of the masticatory muscles (F = 0.704; p &gt; 0.05). The relationship is statistically significant, but weak for ventral dislocation without reposition (p &lt; 0.05; φ = 0.107) and the dorsal arrangement of the disc (p &lt; 0.05; φ = 0.101). In the case of ventral dislocation of the articular disc with the reposition, the relationship is statistically significant, of medium strength (p &lt; 0.05; φ = 0.284).Conclusions. The results of a retrospective analysis of medical documentation confirm the need for instrumental research methods for all patients, regardless of whether they have any complaints at the stage of determining the optimal tactics of orthodontic intervention to obtain diagnostic information on the state of the TMJ in order to prevent the risks of complications during orthodontic treatment.
