Single-Cell RNA Sequencing (scRNA-SEQ) is a new technique for studying the transcriptional activity of a single cell that is still in its early stages of development. It generates transcriptional profiles from thousands of parallel cells to reveal the differential expression of individual cell genomes. They reflect the heterogeneity between cells to identify different cell types and form cell maps of tissues or organs, which play an essential role in biology and clinical medicine. Based on the introduction and comparison of the scRNA-SEQ sequencing platform, this paper focuses on the application of scRNA-SEQ in the exploration of cell types in the nervous system and immune system and summarizes the research results of the combination of scRNA-SEQ and spatial transcriptome technology.","PeriodicalId":94067,"journal":{"name":"Journal of biomedical research & environmental sciences","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77830334","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}

A total of 387 blood samples were collected from internally displaced infected women with the help of a comprehensive filled data form. To determine levels of Cytomegalovirus, Rubella and Toxoplasma gondii Infection, all blood samples were qualitative and quantitative analyzed using Immune chromatographic and Chemiluminescence Microparticle Immunoassay (CMIA) technique. Among 387 blood samples, the total numbers of reactive samples observed were 341 (88.11%) and non-reactive samples were 46 (11.88%). Of 341 (88.11%) reactive samples, the highest ratio 168 (49.26%) was reported for the co-infection of Cytomegalovirus and Rubella, followed by 76 (22.28%) for Cytomegalovirus, Rubella and Toxoplasma gondii combined. In reactive samples, the highest ratio of IgG was noted in order of CMV 22 (64.70%), Rubella 21 (67.74%) and Toxoplasma gondii 16 (72.72%), followed by IgG+IgM and IgM only. Regarding age-wise distribution, the highest ratio 144 (90.56%) of total reactive samples of Cytomegalovirus, Rubella and Toxoplasma gondii was reported in the 25-32 years old group of individuals. Similarly, the highest ratio 53 (48.18%) and 60 (41.66%) of co-infection among reactive samples for Cytomegalovirus, and Rubella was observed in 18-24 and 25-32 years old group. Further, the highest ratio of 100 (40.32%) of risk factors was observed in infected patients who were exposed to a poor hygienic environment and 57 (44.18%) of infected patients had complications of Severe UTI followed by others. Hence, it was revealed that Cytomegalovirus, Rubella and Toxoplasma gondii infection was most prevalent in internally displaced women of District North Waziristan, Pakistan. Therefore, an urgent base prophylactic approaches should need to be addressed to reduce the risk of the spread of disease in this locality.","PeriodicalId":94067,"journal":{"name":"Journal of biomedical research & environmental sciences","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91263558","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}

Now, widespread vaccination appears to be the most important strategy in winning the fight against this deadly pandemic by promoting herd immunity. However, a lack of independent and local studies on vaccines’ safety may adversely impact the vaccine uptake and eventually the overarching goal of reducing disease transmission. Objective: To determine the prevalence of adverse events post COVID-19 vaccination amongst the adult Zambia population. Methods: This was a descriptive cross-sectional study conducted among recipients of COVID-19 vaccines in Zambia. The study was conducted between July and August 2021. 584 adult individuals who had access to the questionnaire were enrolled. Relationships between patients' demographics and Adverse Events (AEs) were assessed using the chi-square (χ2) test given the categorical nature of the data. Results: Pain at the injection site (79.8%), headache (57.4%), fatigue (55.5%), chills (52.6%), fever (42.3%), and joint pains (37.5%) were the most commonly reported adverse events. When stratified by gender, pain at the injection site (p = 0.01), limitation of arm movement (p < 0.001), chills (p = 0.017), headache (p = 0.044), fatigue (p = 0.004), nausea or vomiting (p < 0.001) were statistically significant, with females mostly affected. There was a statistically significant difference in the case of limitation of arm movement (20.7% vs. 9.9%, p = 0.031), chills (54.8% vs. 36.6%, p = 0.004), headache (59.6% vs. 40.8%, p = 0.003) and fatigue (57.5% vs. 40.8%, p = 0.008) between those 49 years and below compared to those above 50 years. Conclusion: Our study provides evidence of adverse events being experienced by the recipient of COVID-19 vaccines and that these have been mainly mild. Healthcare authorities need to educate the public about the possible adverse events associated with COVID-19 vaccines and how to report these events should they experience some. This will improve pharmacovigilance of adverse events associated with COVID-19 vaccines.","PeriodicalId":94067,"journal":{"name":"Journal of biomedical research & environmental sciences","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84780920","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}

Especially in fabricating anticancer candidates, functional composites are divided into different sorts with different characteristics. Additionally, nanotechnology provides various approaches in utilizing composites’ functionality for cancer diagnostics and therapeutics. Compared with previous Photodynamic Therapy (PDT), Photo-Thermal Therapy (PTT), chemotherapy and radiotherapy, ultrasound is used to activate sonosensitizer to produce cytotoxic Reactive Oxygen Species (ROS) toward target cancer cells. In recent years, the form of Sonodynamic Therapy (SDT) has been making much effort to develop highly efficient metal based Nanomaterials (NMs) as sonosensitizers, which can efficiently generate ROS and has the advantages of deeper tissue penetration. However, the traditional sonosensitizers, such as porphyrins, hypericin, and curcumins suffer from complex synthesis, poor water solubility, and low tumor targeting efficacy. For contrasting this limitation, the metal based inorganic NMs show biocompatibility, controllable physicochemical properties, and ease of achieving multifunctional properties, which greatly expanded their application in SDT. In this review, we systematically summarize the metal based inorganic NMs as carrier of molecular sonosensitizers, and produce ROS under ultrasound. Moreover, the prospects of advanced metal based further materials application are also discussed.","PeriodicalId":94067,"journal":{"name":"Journal of biomedical research & environmental sciences","volume":"65 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86819409","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}
