A review on the most important management of keratocystic odontogenic tumor PÅ�ehled nejdůležitÄ�jÅ¡Ãch metod léÄ�by keratocystického odontogennÃho tumoru
No full textBackground: Keratocystic odontogenic tumor (KCOT) is a recurrent benign tumor with a keratinized epithelial shape. The treatment methods in KCOT are still debated. The aim of all treatment methods is to eradicate the cyst and to reduce recurrence and surgical complications. This review article was conducted to assess the findings of studies on the diagnosis, management and recurrence of KCOT. Methods: Information were gathered by searching keywords such as management, treatment, pharmacology, surgery and keratocystic odontogenic tumor in international databases such as Web of Science, PubMed and Scopus. The search period was between 2010-2020. Results: Techniques used for the treatment include decompression, marsupialization, enucleation with or without adjunct, Caldwell-Luc surgery and resection. Of the 40 studies, recurrence was observed in 13 studies and the recurrence ranged from 0 to 48 in different treatment methods. Conclusion: Due to the high recurrence of this disease, it is suggested that long term follow-up be considered after treatment to reduce recurrence. Decision on the treatment should be made considering age, tumor size, and the site of involvement in order to reduce the economic and psychological burden of the disease. © 2022, Czech Medical Association J.E.

A Systematic Review on Curcumin and Anti-Plasmodium berghei Effects
No full textBACKGROUND: Turmeric (Curcuma longa L.) is a popular spice containing curcumin that is responsible for its therapeutic effects. Curcumin with anti-inflammatory, antioxidant, anti-cancer, and antimicrobial activities has led to a lot of research focusing on it over the years. This systematic review aimed to evaluate research on the anti-Plasmodium berghei activity of curcumin and its derivatives. METHODS: Our study was performed according to PRISMA guidelines and was recorded in the database of a systematic review and preclinical meta-analysis of CAMARADESNC3Rs (SyRF). The search was performed in five databases, namely Scopus, PubMed, Web of Science, EMBASE, and Google Scholar, from 2010 to 2020. The following keywords were searched: "Plasmodium berghei", "Medicinal Plants", "Curcumin", "Concentration", Animals kind", "Treatment Durations", "Routes of Administration" and "in vivo". RESULTS: Of the 3,500 papers initially obtained, 14 articles were reliable and were thus scrutinized. Animal models were included in all studies. The most commonly used animal strain was Albino (43), followed by C57BL/6 (22). The other studies used various murine strains, including BALB/c (14) and ICR (7). Two (14) studies did not mention the strain of animal model used. Curcumin alone or in combination with other compounds depending on the dose used, route of administration, and animal model showed a moderate to strong anti-Plasmodium berghei effect. CONCLUSION: According to the studies, curcumin has anti-malarial effects on Plasmodium berghei, and, however, its effect on human Plasmodium is unclear. Due to the side effects and drug resistance of current drugs in the treatment of human malaria, the use of new compounds with few or no side effects, such as curcumin, is recommended as an alternative or complementary treatment.

Application of multi-criteria decision-making for optimizing the formulation of functional cookies containing different types of resistant starches: A physicochemical, organoleptic, in-vitro and in-vivo study
No full textThis research aimed to develop a healthy cookie formulation containing different types of resistant starch, through the application of TOPSIS approach, as a potent feature of MCDM methodologies. Physicochemical investigations reveled that a harder, denser and less sticky dough was produced by the addition of both types of RS. The baking of these doughs resulted in the production of crumblier cookies of less spread ratio, lower porous crumb and whiter surface/crumb. Moreover, in-vitro digestibility of the cookies demonstrated that the baking process can adversely reduce the resistance of RS4 to the enzymolysis reactions. This phenomenon was further corroborated by in-vivo studies where the RS4 enriched cookies were less capable in reducing the postprandial blood glucose. TOPSIS, through successful solving of the multiple criteria decision 9 (alternatives) � 15 (evaluated attributes) matrix suggested that the cookie containing 15 RS is the best alternative in all aspects, possessing acceptable physicochemical/organoleptic attributes, and in-vivo/in-vitro dietary fiber. © 2022 Elsevier Lt
Six new triterpenoids from the root of Potentilla reptans and their cardioprotective effects in silico
No full textTormentic acid ester glucosides derivatives (1, 2 and 4), 3-oxoursane ester glycoside (3) and 11-methoxy-ursane ester glycosides (5, 6) as six new triterpenoids, along with catechin were isolated from the ethyl acetate fraction of Potentilla reptans root (Et) methanolic extract. The structures of the compounds were elucidated by 1D, 2D NMR, IR and MS spectroscopy. Additionally, isolated triterpenoid compounds (1�6) and catechin were evaluated for their cardioprotective effects via glycogen synthase kinase 3β (GSK-3β) and glucocorticoid regulated kinase-1 (SGK1) protein kinase inhibition by Molecular Docking. Compound 1 and catechin (compound 7) exhibited significant inhibitory effects against GSK-3β and SGK1 protein kinases with a binding energy value �9.1 and �8.8 kcal/mol, respectively. Hence, Et can be a suitable natural candidate to protect cardiomyocytes injury. © 2021 Informa UK Limited, trading as Taylor & Francis Group
Outcomes of Repair and Reconstruction of the Acute Posterolateral Corner Injuries of the Knee Combined with Cruciate Ligaments Injuries
No full textBackground: This study aimed to report objective and subjective knee stability scores for patients who underwent acute repair of avulsed posterolateral corner (PLC) structures or acute reconstruction of midsubstance tears combined with delayed reconstruction of cruciate ligaments. Methods: A total of 48 sport and vehicle accident traumatic patients were enrolled in a three-year follow-up study. The patients were investigated by clinical exams, subjective and objective International Knee Documentation Committee (IKDC) score, Tegner score, Lysholm score, and stress imaging. All scores were compared between the reconstruction and repair groups. Results: Subjective IKDC scores were obtained at 83.3±9.6 and 88.3±4.39 for the reconstruction and repair groups, respectively. Only two patients in the reconstruction group had abnormal objective IKDC scores. Based on the Tegner score, 15 out of 18 patients in the repair group and 20 out of 24 patients in the reconstruction group regained their pre-injury functional level. Mean Lysholm scores for the reconstruction and repair groups were estimated at 83.4±8.2 and 88.2±4.1, respectively. Mean lateral joint opening differences between two knees in the reconstruction and repair groups were -0.2±0.1mm and 0.5±0.1mm, respectively. There were no statistically significant differences between groups outcomes. We had no failure of treatment at the final follow-up. Conclusion: Acute intervention within 3 weeks after PLC injuries combined with delayed cruciate ligaments reconstructions showed favorable outcomes. Both repair and reconstruction are effective when deciding based on the type of injury (i.e., avulsion and midsubstance tear). © 2022 Mashhad University of Medical Sciences. All rights reserved
Iranian future healthcare professionals' knowledge and opinions about rare diseases: cross-sectional study
No full textBackground: Rare diseases are a new global health priority, requiring evidence-based estimates of the global prevalence of diseases to inform public policymakers and provide a serious challenge to the healthcare system that must not be ignored. The purpose of this study is to investigate Iranian future healthcare professionals' knowledge and opinions about rare diseases. Results: A total of 6838 students responded to the questionnaire. Nursing and medical students had the highest participation. Almost 85 of participants rated their knowledge about rare diseases as poor or insufficient. While nearly 70 percent of participants took courses about rare diseases at university. Finally, 72.7 of future healthcare professionals did not feel ready to take care of a patient with a rare disease. Conclusion: The present study has indicated a gap in Iranian medical students� knowledge of rare diseases. The researchers believe that health science policymakers should make a joint effort to improve knowledge about rare diseases. Including courses with regard to rare diseases would be of benefit to future healthcare professionals. © 2022, The Author(s)
Association between moral intelligence, burnout and quality of nursing care
No full textBackground: Providing quality care is of the fundamental elements of holistic nursing practice, and burnout and moral intelligence of nurses be mentioned as the important factors influencing the quality of nursing care. The present study was conducted to investigate the relationship between moral intelligence, burnout, and the quality of nursing care. Methods: This descriptive-correlative study was conducted on 125 nurses working in Sari-based Educational hospitals affiliated to Mazandaran University of Medical Sciences, Iran, between June and August 2020. The sample was selected via random sampling. The data were collected by the Maslach Burnout Inventory, Lennick and Kiel Moral Intelligence Scale, and Quality of Patient Care Scale. The data were analyzed by SPSS-21 and Amos-24. Results: A direct and significant relationship was found between the quality of nursing care and moral intelligence (r = 0.285, p = 0.001). Quality of care had an inverse relationship with subscales of frequency of burnout including emotional exhaustion (r = �0.369, p < 0.001) and depersonalization (r = �0.471, p < 0.001) and also, a direct relationship with personal accomplishment (r = 0.226, p = 0.011). The findings also showed an inverse relationship between quality of care and subscales of the intensity of burnout. Amos software yielded results that demonstrated moral intelligence as a robust mediator between burnout and the quality of care. Conclusion: The findings implied the necessity for more attention to moral intelligence as a mediator in order to come up with properly managing the personality traits influencing the nurses� burnout reduction, which can ultimately lead to improved quality of nursing care. © The Author(s) 2021
Enhanced electrocatalytic degradation of 2,4-Dinitrophenol (2,4-DNP) in three-dimensional sono-electrochemical (3D/SEC) process equipped with Fe/SBA-15 nanocomposite particle electrodes: Degradation pathway and application for real wastewater
No full text2,4-dinitrophenol (2,4-DNP), which is a nitrophenol compound, is a carcinogenic and non-biodegradable pollutant, which is found at high concentrations in industrial wastewater. Degradation of 2,4-DNP using a three-dimensional sono-electrochemical (3D/SEC) process equipped with G/β-PbO2 anode and Fe/SBA-15 nanocomposite particle electrodes was evaluated in the present study. Investigating the effect of parameters including pH, electrolysis time, current density, and 2,4-DNP concentration on the performance of the 3D/SEC-Fe-SBA-15 process in 2,4-DNP degradation was considered, and optimization of these parameters was done using the Taguchi design technique. Field emission scanning electron microscopy (FESEM), X-ray diffraction analysis (XRD), energy-dispersive X-ray spectroscopy mapping (EDX-mapping), transmission electron microscopy (TEM), and Fourier Transform Infrared Spectroscopy (FTIR)) were the analyses techniques used to support the successful synthesis of Fe-SBA-15 and G/β-PbO2 anode. The optimum values obtained for pH, electrolysis time, current density, and 2,4-DNP concentration were 5.0, 60.0 min, 5.0 mA/cm2, and 50.0 mg/L, respectively. The experimental removal efficiencies of 2,4-DNP, COD, and TOC using 3D/SEC-Fe-SBA-15 process, under the mentioned conditions, were obtained to be 96.3, 88.28, and 83.82, respectively. In addition, the AOS value was developed from �0.29 to + 0.88; this indicates the high mineralization of 2,4-DNP and improvement of the solution biodegradability. Detecting the intermediates produced during the degradation process was done by LC-MS analysis, and pathways for its degradation was proposed. Results were indicative of the high potential of the 3D/SEC-Fe-SBA-15 process for treating wastewater containing phenolic compounds, e.g., 2,4-DNP, and can provide acceptable efficiency. © 2022 The Author(s
Evaluation of biochemical characteristics of 183 COVID-19 patients: A retrospective study
No full textIntroduction and aim: Coronavirus disease 2019 (COVID-19), with a high mortality rate, has caught the eyes of researchers worldwide and placed a heavy burden on the health care system. Accordingly, this study aimed to evaluate the values of biochemical parameters on the outcomes of COVID-19 patients in Golestan, Iran. Materials and methods: This retrospective study was conducted on 183 COVID-19 patients (i.e., 94 males and 89 females) between March and September 2020. The biochemical parameters and demographic data of the patients (including age, sex, urea, creatinine Cr, lactate dehydrogenase LDH, and creatine kinase CK) were obtained from electrical medical records. According to the outcome of COVID-19, the patients were categorized into two groups (i.e., death n = 63 and survival n = 120 groups), and the biochemical parameters and outcomes of COVID-19 were analyzed. Results: Of the 183 patients, 120 (65.5%) had a non-severe type and recovered from COVID-19, and 63 (34.4%) developed into a critically severe type and died. The mean age of all patients was 56.5 years old. The highest mortality was observed in patients with LDH �280. The data obtained by the one-sample t-test showed that there were significantly higher mean values of urea, Cr, CK, and LDH in COVID-19 patients when compared to their reference intervals (P�0.0001 for all). Conclusions: Some biochemical parameters are effective in the evaluation of dynamic variations in COVID-19 patients. It can be concluded from the results that biochemical parameters and reinforce LDH may be useful for the evaluation of the COVID-19 outcome. © 202
Significance of Cardiac Troponins as an Identification Tool in COVID-19 Patients Using Biosensors: An Update
No full textCoronavirus disease 2019 (COVID-19) has rapidly developed as a global health emergency. Respiratory diseases are significant causes of morbidity and mortality in these patients with a spectrum of different diseases, from asymptomatic subclinical infection to the progression of severe pneumonia and subsequent acute respiratory distress syndrome. Individuals with cardiovascular disease are more likely to become infected with SARS-CoV-2 and develop severe symptoms. Hence, patients with underlying cardiovascular disease mortality rate are over three times. Furthermore, note that patients with a history of cardiovascular disease are more likely to have higher cardiac biomarkers, especially cardiac troponins, than infected patients, especially those with severe disease, making these patients more susceptible to cardiac damage caused by SARS-2-CoV. Biomarkers are important in decision-making to facilitate the efficient allocation of resources. Viral replication in the heart muscle can lead to a cascade of inflammatory processes that lead to fibrosis and, ultimately, cardiac necrosis. Elevated troponin may indicate damage to the heart muscle and may predict death. After the first Chinese analysis, increased cardiac troponin value was observed in a significant proportion of patients, suggesting that myocardial damage is a possible pathogenic mechanism leading to severe disease and death. However, the prognostic performance of troponin and whether its value is affected by different comorbidities present in COVID-19 patients are not known. This review aimed to assess the diagnostic value of troponin to offer insight into pathophysiological mechanisms and reported new assessment methods, including new biosensors for troponin in patients with COVID-19.
