Background: Coenzyme Q (CoQ) is an enzyme family that plays a crucial role in maintaining the electron transport chain and antioxidant defense. CoQ₁₀ is the most common form of CoQ in humans. A deficiency of CoQ₁₀ occurs naturally with aging and may contribute to the development or progression of many diseases. Besides, certain drugs, in particular, statins and bisphosphonates, interfere with the enzymes responsible for CoQ₁₀ biosynthesis and, thus, lead to CoQ₁₀ deficiency.

Objectives: This article aims to evaluate the cumulative studies and insights on the topic of CoQ₁₀ functions in human health, focusing on a potential role in maintaining physical activity and extending the life cycle.

Results: Although supplementation with CoQ₁₀ offers many benefits to patients with cardiovascular disease, it appears to add little value to patients suffering from statin-associated muscular symptoms. This may be attributed to substantial heterogeneity in doses and treatment regimens used.

Conclusion: Therefore, there is a need for further studies involving a greater number of patients to clarify the benefits of adjuvant therapy with CoQ₁₀ in a range of health conditions and diseases.

Introduction: Skin damage is a serious problem that has attracted remarkable attention. Recently, the healing of wounds has become a serious problem. Hence, the aim of this study was to conduct an ethnobotanical study about medicinal plants used for the healing of wounds in Sistan and Baluchestan Province, Southeastern Iran. Methods: This study was performed in Sistan and Baluchestan Province, Southeastern Iran. Ethnobotanical information was collected through interviews and questionnaires among 20 traditional healers. Demographic information was also obtained from traditional healers. The data were analyzed by Excel. Results: Eleven medicinal plants from nine families were used for wound healing. The medicinal plants from the Fabaceae family (Alhagi persarum Boiss. & Buhse. and Medicago sativa L.) had the most application for wound healing. It has been observed that topical administration was the most important type of preparation method for the used medicinal plants. According to the new results, most plant families belong to Zygophyllaceae and Fabaceae. The most used plant organ was the leaf (53%) and the most used method was as topically. Conclusion: The mentioned medicinal plants showed wound-healing effects. Further research is needed for the suitable application of these plants and their phytochemical constituents in the medical and pharmaceutical industries.

Introduction: The treatment of most diseases in dentistry is related to the local application of antiseptic drugs that regulate the microbiocenosis in the oral cavity. The study of pharmacodynamic and kinetic parameters of the release of active pharmaceutical ingredients (APIs) from the dosage form (DF) is an important task. In this study, we tried to evaluate the release of APIs from developed dental medicinal films (DMF) produced on a polymeric basis. Methods: To confirm the antimicrobial activity of the three developed DMF with amizon, decamethoxine and chlorhexidine digluconate, a statistical analysis and mathematical processing of the research results were carried out. Results: Statistical processing made it possible to organize the results of our earlier studies, in which the concentrations of three APIs (amizon, decamethoxine, and chlorhexidine digluconate) were determined during their diffusion from the polymer base of the DMF to the aqueous dispersion medium (0.9% sodium chloride solution). Due to performed statistical calculations, regarding the reliability of APIs release, it was determined that the time duration of complete release of the three active substances from the polymer base was different, which will ultimately affect the duration of the pharmacological effect of the APIs in the patient's body. Conclusion: In the manufacture of DMF on a polymeric base of hydrophilic type, it is necessary to take into account the release time of each API, according to the composition of the polymeric coatings.

Methylmercury (MeHg) is a global environmental pollutant with neurotoxic effects. Exposure to MeHg via consumption of seafood and fish can severely impact fetal neurobehavioral development even when MeHg levels in maternal blood are as low as about 5 μg/L, which the mother tolerates well. Persistent motor dysfunctions and cognitive deficits may result from trans-placental exposure. The present review summarizes current knowledge on the mechanisms of MeHg toxicity during the period of nervous system development. Although cerebellar Purkinje cells are MeHg targets, the actions of MeHg on thiol components in the neuronal cytoskeleton as well as on mitochondrial enzymes and induction of disturbances of glutamate signaling can impair extra-cerebellar functions, also at levels well tolerated by adult individuals. Numerous herbal substances possess neuroprotective effects, predominantly represented by natural polyphenolic molecules that might be utilized to develop natural drugs to alleviate neurotoxicity symptoms caused by MeHg or other Hg compounds.
