The mRNA vaccine Comirnaty was the first conditionally licensed vaccine against SARS-CoV-2. Its key ingredient is a fragment of matrix RNA obtained by in vitro transcription that corresponds to the sequence that encodes the spike protein (S protein) of the SARSCoV-2. Today, it is well established that in the face of the continued evolution of the SARS-CoV-2, the effectiveness of the vacci-nation in the core regimen is not sufficient to prevent infection. However, the sustained high level of vaccine protection against severe forms of COVID-19 can significantly reduce hospitalizations and deaths. In addition, the documented risk of serious adverse events following each dose of the vaccine appears relatively small compared to the potential health consequences of COVID-19 infection. This article presents scientific studies describing the role of the Comirnaty vaccine in the prevention of COVID-19 infection and severity.","PeriodicalId":91594,"journal":{"name":"Pomeranian journal of life sciences","volume":"68 1","pages":"25 - 29"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48628071","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}

It is particularly high in the 3rd quarter of each year, which is accompanied by an increase in the number of mushroom poisonings. This study aims to present difficulties with microscopic identification, the most popular method for diagnosing mushroom poisoning in hospital settings, when it comes to detecting Amanita phalloides spores in biological material. Materials and methods: Spore analysis was carried out using aqueous solutions containing reference spores of different mushrooms: death cap (Amanita phalloides), parasol mushroom (Macrolepiota procera), field mushroom (Agaricus campestris), yellow knight mushroom (Tricholoma equestre), and green cracking russula (Russula virescens). The spore analysis was also carried out for a meal (soup) containing selected spores. Spores were identified using a light microscope and staining with Sudan III and Meltzer’s reagent. A statistical analysis of mushroom poisoning cases was also performed at the Department of Clinical and Forensic Toxicology, Pomeranian Medical University in Szczecin using records for 2015–2019. Conlusions: Analysis of data from 2015–2019 from the Department of Clinical and Forensic Toxicology at the Pomeranian Medical University in Szczecin showed a marked increase in mushroom poisoning cases in the 3rd quarter of each year. Analysis of materials containing Amanita phalloides spores revealed their high similarity to oil drops and other cell structures present in biological material, resulting in the low reliability of microscopic identification. Therefore, as the absence of Amanita phalloides spores in the tested biological material does not rule out poisoning with this mushroom, a more advanced instrumental analysis (ELISA, LC/MS) is recommended.","PeriodicalId":91594,"journal":{"name":"Pomeranian journal of life sciences","volume":"68 1","pages":"20 - 24"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41522239","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 aim of the study is to present, on the basis of a literature review, the basic structure, properties and indications for the use of dental materials used in direct restorative dentistry, as well as new self-adhesive hybrid materials with simplified application technique. These are: Activa BioActive Restorative (Pulpdent; AB), Cention N (Ivoclar-Vivadent; CN), and SureFil One (Dentsply Sirona; SO). Basic information on the chemical structure and basic indications for the use of these materials were presented. Conclusions: The presented new materials are evolutionary products based on conventional glass ionomer cements (GIC), resin-modified glass ionomer cement (RM-GIC) and composite materials. The chemical structure and reactions that occur during the binding of AB and SO materials are similar to some RM-GIC, while in the case of CN material similar to fluorine-releasing resin-based materials. Previous studies do not confirm that the new materials have mechanical properties necessary to meet the requirements for posterior restorations. Considering limited clinical trials, care should be taken in their systematic application in all patients. There are no unequivocal studies confirming the bioactivity of the materials. Further in vitro studies as well as clinical observations to assess their chemical properties and the ability to induce remineralization and bioactivity are needed. The materials show self-adhesion but when included in the protocol of a bonding system, their adhesion to hard tissues is better.","PeriodicalId":91594,"journal":{"name":"Pomeranian journal of life sciences","volume":"68 1","pages":"36 - 44"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46549476","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}

This is especially true of micronutrients, including zinc. Yet despite the importance of zinc in the human body, there is a paucity of data on the zinc status of Nigerian children. The aim of this study was to determine serum zinc levels, anthropometry, dietary zinc content and socioeconomic status (SES) of school-aged children in the cities of Osogbo and Ogbomoso in South West Nigeria during the COVID-19 pandemic. Materials and methods: One hundred and forty-one children (aged 9–17) were recruited for the study, 76 children from Osogbo and 65 children from Ogbomoso. Serum zinc levels were determined using atomic absorption spectrometry. Information on SES and dietary zinc content were obtained using a structured questionnaire. Anthropometric indicators – height, weight, body mass index (BMI), and mid-upper arm circumference (MUAC) were also measured. Data were analysed statistically using Student’s t-test and Pearson’s correlation coefficient p < 0.05 was considered significant. Results: Results of the study showed that there were no significant differences in the values of zinc, BMI, and MUAC, when both groups were compared. Majority of the students in each group were of medium SES. Sixty percent (Ogbomoso) and 43% (Osogbo) did not consume food rich in zinc, although calculated BMI-for-age percentiles revealed that 89.23% (Ogbomoso) and 71.05% (Osogbo) were of normal weight. Mid-upper arm circumference of <22.0 cm for both groups suggests moderate acute malnutrition despite the fact that a correlation was observed between MUAC and BMI. Conclusions: The results of the study indicate that moderate zinc deficiency is still prevalent among school-aged children in South West Nigeria and this requires urgent intervention from different stakeholders.","PeriodicalId":91594,"journal":{"name":"Pomeranian journal of life sciences","volume":"68 1","pages":"61 - 66"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42278403","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}

These include high species diversity of the spirochete causing LD and the lack of a treatment that could guarantee a complete and sustained eradication of infection in all patients. Therefore, the current study aimed to evaluate the effectiveness of treatment of patients with LD based on the measurement of LD-related antibodies generated in response to the highly immunogenic VlsE antigen evaluated using enzyme-linked immunosorbent assay (Lyme Trace ELISA). Materials and methods: The study group consisted of 10 healthy volunteers (control group) and 21 outpatients (experimental group) with LD, living in the West Pomeranian Province of Poland. The serum samples of the experimental and control groups were tested with the anti-Borrelia IgG plus VlsE ELISA, anti-Borrelia IgG immunoblot, and anti-VlsE IgG Lyme Trace ELISA. Results: Research showed that the mean value of anti-VIsE IgG antibody concentration decreased after treatment by 41.6%, 35.9%, and 31.7% in the serum dilutions 1:101, 1:1010, and 1:10100, respectively. A statistically significant difference was obtained in antibody concentration in the serum dilution 1:101 before (R) and after (R*) treatment. The R/R* ratio presented at least a 4-fold decrease in antibody concentration in 2 patients (9.5%), thereby suggesting the effectiveness of the therapy. In serum samples diluted at 1:101 and 1:1010, antibody levels showed an increase after treatment in 7 patients (33.3%), and at a dilution of 1:10100, this increase was found in 6 patients (28.6%). The R/R* ratio differed significantly between the subgroups, where the antibody concentration increased after treatment and then decreased. Conclusion: Summing up, it can be concluded that the Lyme Trace ELISA assay used in the study to assess the level of anti-VlsE IgG antibodies showed insufficient satisfactory results in the assessment of monitoring the effectiveness of treatment in patients with LD before and after the treatment. The assessment of the effectiveness of treatment should, as such, still be based on the evaluation of the clinical symptoms of the disease, treating the quantification of IgG antibodies with the use of recombinant VlsE antigens as an additional tool.","PeriodicalId":91594,"journal":{"name":"Pomeranian journal of life sciences","volume":"68 1","pages":"18 - 24"},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45201189","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}
