Hericium erinaceus is a medicinal fungal species that produces the active biological metabolite erinacine A with strong antioxidant activity. The classical extraction techniques used to date to obtain metabolites from this fungal species require high consumption of resources and energy and, in the end, prove to be expensive and inefficient, especially on a biomedical scale. The aim of this research is based on the development of an ultrasonic extraction (UE) method for the identification and extraction of biological compounds with high antioxidant activity from the mycelia of H. selleck chemicals erinaceus biomass developed through a solid cultivation process. The extraction process was optimized by varying parameters to determine the best extraction yield of metabolites involved in such antioxidant activity, using the response surface methodology (RSM). The physicochemical analyses were oriented towards the investigation of polyphenols, flavonoids, and the diterpenoid erinacine A. It is highlighted that there is a very good mutual connection between the concentration of polyphenols and flavonoids in the extracts studied and the diterpenoid erinacine A. Also, this study describes an efficient and qualitative extraction method for extracting natural antioxidants from the H. erinaceus mushroom, since toxic solvents were not used in the developed extraction procedure. This biomass can be used both as a food source and as a possible phytotherapeutic tool in the prevention or treatment of various neurodegenerative disorders that require drugs with strong antioxidant activity.Gastrin-releasing peptide receptor (GRPR) is overexpressed in the majority of prostate cancers. This study aimed to investigate the potential of 64Cu (radionuclide for late time-point PET-imaging) for imaging of GRPR expression using NOTA-PEG2-RM26 and NODAGA-PEG2-RM26. Methods NOTA/NODAGA-PEG2-RM26 were labeled with 64Cu and evaluated in GRPR-expressing PC-3 cells. Biodistribution of [64Cu]Cu-NOTA/NODAGA-PEG2-RM26 was studied in PC-3 xenografted mice and compared to the biodistribution of [57Co]Co-NOTA/NODAGA-PEG2-RM26 at 3 and 24 h p.i. Preclinical PET/CT imaging was performed in tumor-bearing mice. NOTA/NODAGA-PEG2-RM26 were stably labeled with 64Cu with quantitative yields. In vitro, binding of [64Cu]Cu-NOTA/NODAGA-PEG2-RM26 was rapid and GRPR-specific with slow internalization. In vivo, [64Cu]Cu-NOTA/NODAGA-PEG2-RM26 bound specifically to GRPR-expressing tumors with fast clearance from blood and normal organs and displayed generally comparable biodistribution profiles to [57Co]Co-NOTA/NODAGA-PEG2-RM26; tumor uptake exceeded normal tissue uptake 3 h p.i.. Tumor-to-organ ratios did not increase significantly with time. [64Cu]Cu-NOTA-PEG2-RM26 had a significantly higher liver and pancreas uptake compared to other agents. 57Co-labeled radioconjugates showed overall higher tumor-to-non-tumor ratios, compared to the 64Cu-labeled counterparts. [64Cu]Cu-NOTA/NODAGA-PEG2-RM26 was able to visualize GRPR-expression in a murine PC model using PET. However, [55/57Co]Co-NOTA/NODAGA-PEG2-RM26 provided better in vivo stability and overall higher tumor-to-non-tumor ratios compared with the 64Cu-labeled conjugates.Endocan, a potential biomarker of endothelial dysfunction, is associated with increased cardiovascular risk. We investigated the utility of plasma endocan for predicting cardiovascular risk in end-stage renal disease (ESRD) patients undergoing hemodialysis. Of the 452 patients in the K-cohort, 354 with available plasma endocan levels were enrolled. The correlation between plasma endocan levels and the clinical characteristics of a study population were analyzed. We divided patients into two groups, according to plasma endocan levels, and investigated the predictive value of endocan for the occurrence of cardiovascular events. In a multiple linear regression analysis, plasma endocan levels were positively correlated with previous cardiovascular events and negatively correlated with body mass index, albumin, and triglyceride. Patients with higher plasma endocan levels experienced more frequent cardiovascular events than those with lower plasma endocan levels (12.9% in the lower group vs. 22.7% in the higher group, p = 0.016). Cox proportional hazard models showed that higher plasma endocan levels were an independent predictor of cardiovascular events in ESRD patients on hemodialysis ((hazard ration) HR 1.949, 95% (confidence interval) CI 1.144-3.319, p = 0.014). Our results suggest that plasma endocan level might be a useful biomarker for predicting cardiovascular events in ESRD patients on hemodialysis.Several studies have shown that communication between patients and HCPs is still not optimal in integrating patients' perspectives on how best to manage their diseases and their medication. One such area where encounters between patients and professionals still needs to develop to better incorporate the patient's perspective is pharmacy practice. The aim of this study was therefore to explore and present new typologies and communication aspects of HCP-patient relationships since a comprehensive literature search in 1997 conducted by Sondell and Söderfeldt, and relate the findings to pharmacy practice. In total, 11 articles were identified by applying the techniques of a purposeful literature search. The articles covered aspects of shifting and adapting roles during the encounter, techniques to ensure individualizing in the encounter, avoiding inappropriate routines, coping with internet-informed patients, achieving mutual goals, dealing with uncertainty including avoiding rigid preconceptions, using social conversation, incorporating patients' prior experiences, aligning language, adapting greetings and exploring the cultures and communication patterns of patients from other ethnic backgrounds. The variety of these communication aspects points to the immense complexity of communication as a practice discipline. This article has presented some of the literature that pharmacists can consult, in the endeavor of improving their communication practices.Vaccines are fundamental instruments upon which all modern medicine is hinged. This has recently come into the light because of the COVID-19 pandemic caused by SARS-CoV-2. We aimed to assess the knowledge and attitudes of the public regarding vaccination. To this end, a questionnaire, which was disseminated to the general population between 2017 and 2019, was used. We evaluated the responses from 1647 individuals (61% female, with a median age of 37 years, mostly from urban settings). Most respondents (85%) had children and were in favor of vaccination. Our study underlines the role that family physicians have in the education and information of citizens. A small, but considerable, number of respondents (108, 7.84% of those with children) had not vaccinated their children according to the national vaccination scheme. Deterrents were considered to be lack of information and fear of side effects. However, 167 of our respondents (12.12% out of 1377 respondents with children) said that their child experienced adverse events-most of which were mild local reactions.
