Insects, throughout evolution, have developed a huge arsenal of active compounds, which they use to defend themselves against enemies and diseases, at the same time in recent years insects have shown great interest as a source of food rich in biologically active substances. Research in recent decades has shown that insects produce a variety of proteins and peptides with antibacterial, antifungal, antiviral, immunomodulatory, anti-inflammatory, antioxidant, antitumor, hepatoprotective, antithrombotic, antihypertensive and detoxifying activity during or after contact with the microbial agent or unfavourable factor. Material and methods. The anti-inflammatory effect of imuheptin and imupurin was investigated in a rat model of subacute inflammation induced by subcutaneous implantation of felt discs. The intensity of the exudative and proliferative phase of inflammation, cytokine profile (TNFalpha, IL-6, IL-10), ceruloplasmin and antioxidant enzymes (superoxide dismutase, catalase, glutathione reductase, glutathione peroxidase and glutathione-S-transferase) in the serum of rats were evaluated. Results. Imuheptin and imupurin reduced the level of pro-inflammatory cytokines (TNF-alpha, IL-6) and increased that of the anti-inflammatory cytokine (IL-10), as well as ceruloplasmin, glutathione reductase and glutathione peroxidase in subacute inflammation. Additionally, imupurin significantly increased the level of catalase and imuheptin that of glutathioneS-transferase. Conclusions. Imuheptin and imupurin determined a moderate effect of inhibiting the exudative and proliferative processes, compared to the reference preparation - dexamethasone, but with a favourable effect on the cytokine profile, decreasing the level of pro-inflammatory cytokines (TNF-alpha, IL-6) and increasing the level the anti-inflammatory one (IL-10), as well as the modulation of antioxidant enzyme activity.","PeriodicalId":500832,"journal":{"name":"Moldovan Journal of Health Sciences","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135640979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Oxygen-ozone therapy stands as a medically endorsed practice confirmed by numerous international clinical studies. Various authors have illustrated the beneficial clinical outcomes of ozone therapy in terms of its capacity to regulate redox balance, cellular inflammatory responses, and adaptation to ischemia/reperfusion processes. Ozone therapy extends to encompass a range of viral infections, inflammatory disorders, and degenerative ailments, used as both monotherapy and as an adjunct to unified conventional therapies. Material and methods. Narrative literature review study. Bibliographic search was conducted using the PubMed, Hinari, and SpringerLink databases, as well as the National Center of Biotechnology Information and Medline. Articles published between 1990 and 2022 were selected using various combinations of keywords, including “ozone”, “ozone therapy”, “mechanisms of ozone action”, “biological effects of ozone”, “antioxidant effect”, “anti-inflammatory effect” and “immunomodulatory effect.” Information regarding ozone’s mechanisms of action was identified and processed. Following the database information processing and search criteria, a total of 475 full-text articles were found. The final bibliography consists of 52 relevant sources that were deemed representative of the materials published on the topic of this synthesis article. Results. The effects of ozone on oxygen metabolism are explained by changes in the rheological properties of blood, including inhibition of erythrocyte aggregation and stimulation of 2,3-diphosphoglycerate in erythrocytes, favoring the transport and delivery of oxygen to tissues while facilitating the substantial elimination of nitric oxide and increasing blood flow. Intracellular triatomic oxygen enhances the oxidative carboxylation of pyruvate, stimulating ATP production, which also contributes to reducing peripheral vascular resistance. Conclusions. Ozone generates a moderate oxidative stress. Yet, it can set off several beneficial biochemical mechanisms that reactivate both the intra- and extracellular antioxidant systems and reverse chronic oxidative stress in various inflammatory and degenerative processes. Ozone induces a mild activation of the immune system by triggering neutrophil activation and stimulating the synthesis of certain cytokines (IL-2, TNF-α, IL-6, and IFN-γ), thereby initiating a complete cascade of immune responses. Ozone therapy yields the following biological reactions: optimization of blood circulation and oxygen delivery to ischemic tissue, regulation of cellular antioxidant enzymes, initiation of a slight immune system activation, and enhancing the release of growth factors.","PeriodicalId":500832,"journal":{"name":"Moldovan Journal of Health Sciences","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135641150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Endothelial dysfunction is a result of complex pathogenic interface involving inflammation, oxidative stress, disorders of endothelization and hemostasis etc., in both arteries and veins, leading to a lot of cardiovascular diseases. Identifying markers with high predictive value has an important diagnostic and prognostic significance. Material and methods. To create this review article, we conducted a thorough search for relevant references that are current, specific, and aligned with the goals of the article. We utilized databases such as PubMed, MEDLINE, Google Scholar, and Cochrane, going as far back as the year 2000 to gather the necessary information. The identified articles were structured based on the main objectives, comprehensively analyzed, and the key findings have been critically exposed. Results. A few main markers endothelial dysfunction were revealed, which reflect axial pathogenic events such as inflammation, endothelium lesion and reendothelization, inherent hemostasis disorders and prothrombotic risk. Likewise, some distinct morphophysiological traits of arterial and venous endothelium are disentangled, as well as markers having common and distinct predictive power of endothelial dysfunction in arteries and veins. Conclusions. Multi-marker panel is a reliable tool for prediction of endothelial dysfunction in both arteries and veins, as well as the risk of inherent consequences.

Oxidative stress can be defined as the imbalance of the redox state of a certain system including living one (organelle, cell, organ/tissue), which excessively produces reactive oxygen and/or reactive nitrogen species (ROS/RNS) that exceed the capacity of the antioxidant defense system, which have the ability to slow down or even prevent the oxidative damage of macromolecules. Oxidative stress is a pathogenic mechanism of a large variety of diseases, including pulmonary one. Material and methods. 81 preterm born children included in the study were divided into the main group – preterm children with bronchopulmonary dysplasia (BPD), and the control group – preterm children without BPD. The comparison groups were prospectively evaluated clinical, instrumental and laboratory (TPA, prooxidant-antioxidant balance, nitric oxide metabolistes and MDA). Data were statistically analyzed using Microsoft Excel, MedCalc and SPSS and Contingency Table Analysis as a way to evaluate the performance of a diagnostic test. Results. In preterm children with BPD were found to be decreased by 29% (p < 0.001) the prooxidant-antioxidant balance (PAB) and the nitric oxide metabolistes (NO) level by 12% (p < 0.001) compared to children in the control group. The assessment of tissue oxidative damage markers revealed a significant 62% (p < 0.001) increase in malonic dialdehyde (MDA) content and a 4.86-fold (p < 0.001) increase in total prooxidant activity (TPA) in children with bronchopulmonary dysplasia compared to children in the control group. Our study confirms that TPA, PAB, MDA and NO values are reliable markers of hypoxic tissue damage at children with bronchopulmonary dysplasia and can be recommended for assessing the intensity of oxidative stress. Conclusions. Pulmonary bronchodysplasia is characterized by the imbalance of prooxidant-antioxidant processes with the exacerbation of prooxidant ones that trigger the oxidative/nitrosative stress and the deterioration of vital chemical compounds.","PeriodicalId":500832,"journal":{"name":"Moldovan Journal of Health Sciences","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135641149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Open balloon thrombectomy and embolectomy remain the preferred initial option in the management of acute lower limb ischemia (ALI), but various endovascular techniques have become accessible and are growing in popularity. The aim of the study was to assess our early experience with percutaneous vacuum-assisted thromboaspiration using the Penumbra/Indigo® system for non-traumatic ALI. Material and methods. The study group comprised 13 patients with ALI who received treatment between September 2022 and June 2023; with 7 (53.8%) being males. The median age was 71 years (25%-75%IQR 62.5-77.5). ALI cases were classified according to the Rutherford scale: grade I – 2 (15.3%), grade IIA – 7 (53.8%), and grade IIB – 4 (30.7%). In 10 (76.9%) cases, ischemia was classified as “acute-on-chronic.” The occluded native vascular segment, determined through preoperative computer tomography angiography (n=4; 30.7%), duplex scanning (n=5; 38.4%), or both examinations (n=4; 30.7%), were as follows: superficial femoral artery (n=7) and popliteal artery (n=2). In two patients, thrombosis of the below-knee femoropopliteal bypass with autogenous vein was identified, while two others presented with femoral artery stent thrombosis. An embolic etiology of ALI was observed in 4 (30.7%) cases, and thrombotic etiology in 9 (69.2%) cases. Endovascular access was established via the ipsilateral common femoral artery (n=10), crossover (n=2), or brachial artery (n=1). Thromboaspiration was carried out using dedicated CAT6™ and CAT8™ catheters. Results. The technical success rate of vacuum-assisted thromboaspiration was 92.3%. Subsequent angiography revealed accompanying occlusive-stenotic lesions in all instances, necessitating transluminal angioplasty, and in 8 (61.5%) patients, additional stenting was required. Catheter-directed thrombolysis was utilized as an adjunct in one patient. There were 2 (15.3%) instances of distal embolization, both addressed within the same surgical session. Survival and limb salvage rates at the 30th-day follow-up stood at 100%. Conclusions. Utilizing the Penumbra/Indigo® system, percutaneous vacuum-assisted thromboaspiration appears to be a safe and effective minimally invasive technique for treating ALI. This method allows for the concurrent correction of coexisting chronic peripheral arterial lesions.","PeriodicalId":500832,"journal":{"name":"Moldovan Journal of Health Sciences","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135641322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abdominal breathing is utilized as a non-pharmacological treatment method for various stress-related conditions and autonomic dysfunctions. The objective of the study was to determine the predictors in the modulation of sympathovagal balance, as indicated by the ratio of low frequency to high frequency power of heart rate variability, by utilizing the respiratory pattern parameters recorded during the abdominal breathing model. Material and methods. The study involved a group of 101 healthy subjects, where the breathing pattern was recorded using a respiratory induction plethysmograph. Heart activity was estimated through electrocardiography, followed by heart rate variability analysis during both resting and abdominal breathing. Eight parameters of the breathing pattern were recorded in the subjects during resting breathing and abdominal breathing, presumed to be predictors of the ratio of low frequency to high frequency power of heart rate variability. Separate predictive models were created for this ratio for both the resting and abdominal breathing types. Results. The multilinear regression analysis revealed that the primary predictor with the highest predictive power for determining the balance between sympathetic and parasympathetic cardiac influence, as indicated by the low frequency spectral power to high frequency spectral power ratio, in individuals practicing abdominal breathing is Tidal Volume (unstandardized coefficient = 5.007). This was followed by the duration of expiration (coefficient = -3.831) and respiratory minute-volume (coefficient = 4.415), both of which were recorded during resting breathing. In the abdominal breathing model, the most effective predictors were found to be time-related parameters, specifically the frequency of breathing during abdominal breathing (coefficient = -5.953), the duration of the inspiratory phase (coefficient = -4.037), and the duration of the expiration phase (coefficient = -4.194). Conclusions. Abdominal breathing has the potential to normalize sympathovagal balance by adjusting the duration of inspiration or expiration. Further studies should be conducted to investigate the practical application of breathing pattern parameters in restoring the low frequency to high frequency (LF/HF) ratio, particularly in disorders characterized by elevated sympathovagal balance.","PeriodicalId":500832,"journal":{"name":"Moldovan Journal of Health Sciences","volume":"2013 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135640984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The clinical concept that would argue that the activity of the lateral pterygoid muscle, being disturbed, would play an important role as an etiological factor in temporomandibular joint dysfunctions is still widely accepted, being also a decisive factor in the correct choice of the treatment plan. However, because of the fact that very few research and clear evidence were conducted and presented to support completely that concept, it continues to remain a very controversial one. Material and methods. For this literature review were considered and studied scientific articles published between 2000 and 2023, in the following electronic databases: PubMed, MEDLINE, Google Scholar, BIR Publications, ScienceDirect. Research methods – analysis, synthesis, systematization, and description. Results. Patients presenting temporomandibular joint dysfunction complain about pain in the temporomandibular joint or/and in masticatory muscles, limitation and sounds during mandibular activity. Temporomandibular dysfunction is a non-specific collective term, used to describe a heterogeneous group of pathological conditions located in the territory of the stomatognathic system. These are considered musculoskeletal conditions that cause pain while performing the function (mastication, speech, swallowing), with increased sensitivity in the masticatory muscles and/or the temporomandibular joint, with possible limitations of the range of motion, the appearance of joint noises and otological symptoms. One of the theories claims that in temporomandibular dysfunction, the lateral pterygoid muscle becomes hyperactive, hypoactive or that there is a lack of coordination between the superior and inferior branches of the muscle, or that there is a disturbance during the performance of the role of the muscle to control and stabilize the temporomandibular joint. However, the in-depth study of the specialized literature indicates that no scientific evidence is yet available that the function of the lateral pterygoid muscles in temporomandibular dysfunction is somehow disturbed. Moreover, the muscle’s role during the execution of its normal function has also been questioned and remains a matter of controversy. Conclusions. The lateral pterygoid muscle obviously plays an important role in the development of temporomandibular dysfunction through the prism of its anatomical and functional particularities, referring to the superior fascicle responsible for the correct anatomical maintenance of the articular disc during function.","PeriodicalId":500832,"journal":{"name":"Moldovan Journal of Health Sciences","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135640985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
