The perforation of the Schneiderian membrane is one of the most frequent events while performing the detachment of the membrane and it can increase the risk of iatrogenic sinusitis, impairment of functional homeostasis, dispersion of the graft material in the antral cavity as well as its bacterial colonization with a subsequential failure of the procedure. This report presents a case where transcrestal sinus lift was performed using Flusilift (Sweden & Martina, Due Carrare PD), a new instrument that allows fluid dynamic elevation of the sinus floor using saline solution to detach the Schneider’s membrane in an atraumatic way without using a sinus elevator and obtain an adequate alveolar ridge regeneration using hyaluronic acid in gel formulation to support an implant placement. Hyaluronic acid seems to play a key role in wound healing and contributes to a faster bone neoformation in bone regeneration procedures.","PeriodicalId":94067,"journal":{"name":"Journal of biomedical research & environmental sciences","volume":"87 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81255550","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}

Aim: The aim of this review is to highlight Immune response of human body toward COVID-19. Materials and methods: This was a narrative review. A comprehensive literature search was done using PubMed, Google Scholar, Scopus, and EMBASE using the keywords, Immune Response; COVID-19; Vaccination; SARS-Cov-2; ACE2; Coronavirus; MERS. Results: A flow of viral components passes to the body by means of nostrils, mouth and eyes. SARS-CoV-2 is in a position to continue to become unnoticed extended than numerous influenza or coronaviruses. Its proteins can accomplish entry by unlocking the Angiotensin-Converting Enzyme 2 (ACE2) protein in the lung cells; viruses also possess antigens furthermore recognize that these are what cries the immunity into movement via making antibodies. Investigators demonstrate an extensive variety of immune cells respond to COVID-19 along with valuable source retrieval, discovering that might want to notify the manufacturing of a viable vaccination. Conclusion: The body's natural response to a viral infection is a non-invasive intrinsic response in which macrophages, neutrophils, and dendritic cells limit the virus's progression and may even prevent it by multiplying symptoms. This non-invasive solution is accompanied by an elastic response in which the body produces radicals that primarily adjust to the herpes virus.","PeriodicalId":94067,"journal":{"name":"Journal of biomedical research & environmental sciences","volume":"46 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87012403","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}

Despite the advent of COVID-19 vaccines, pandemic fatigue is still escalating as new SARS-CoV-2 variants emerge and vaccine shortages hit globally. Hence, drug repurposing remains an alternative strategy to combat SARS-CoV-2. For centuries, plants have served as natural reservoirs of pharmacologically active compounds with minimal cytotoxicity and promising antimicrobial and antiviral activities. In this light, the present study was undertaken to virtually screen 33 phytochemicals across various cultivars against the main protease (Mpro) and Spike (S) protein of SARS-CoV-2 using ADME analysis. 31 phytochemicals obeying Lipinski’s rules were subjected to molecular docking using AutoDock Vina. Docking scores were determined by selecting the best conformation of the protein-ligand complex that exhibited the highest affinity. The study identified withanone, licoflavone A, and silibinin to interact with the S protein at the hACE2-binding site with high binding energies. Similarly, myricitrin, withanone, naringenin, licoflavone A, and silibinin exhibited high binding affinities with the substrate-binding pocket of Mpro between the domains I and II. Interestingly, licoflavone A, silibinin, and withanone interacted with both Mpro and S proteins in silico. Further, drug-likeness studies indicated withanone to be the most readily bioavailable phytochemicals among the three shortlisted ligands. Therefore, phytochemicals can be regarded as potential leads for developing inhibitors against this mysterious virus. In vitro investigations are further warranted to prove their antiviral efficacy.","PeriodicalId":94067,"journal":{"name":"Journal of biomedical research & environmental sciences","volume":"37 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85143071","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}

By merging eight tribal dominating districts namely, Banswara, Chittourgarh, Dungarpur, Pali, Pratapgarh, Rajasamand, Sirohi, and Udaipur of these, the government has created a special area called the ‘schedule area” in which >70% of the people are tribal. This area is mostly backward and underdeveloped where malaria is also hyperendemic. In this area, Bhil, Damor, Meena, Garasiya, Kathudia and Sahariya are the most dominating and major endogamous tribes. Besides the several communicable and non-communicable diseases in this area, certain erythrocyte genetic disorders, Sickle-Cell Haemoglobin (Hb-S), β-thalassaemia and G-6-PD deficiency (Gd) are also deteriorating the tribal health and causing morbidity and mortality in them. Genes of these red cell genetic disorders are more prevalent and widely distributed among tribal people. The maximum prevalence of these blood genetic disorders in tribes was found as 31.14%, 9.00% and 22.00%, respectively. Since the groundwater of this tribal area contains a high amount of Fluoride (F), drinking it poses a high risk of premature death of tribal people who already have homozygous state of sickle-cell and β-thalassaemic genes. In present communication, besides the focus on tribal health, the status of genes of sickle-cell haemoglobin, β-thalassaemia and G-6-PD deficiency in different tribal ethnic groups of scheduled area, the correlation of these blood genetic disorders with malaria, impact of F intoxication in tribal subjects possessing red cell genetic disorders and the prevention and control of these erythrocyte genetic disorders in tribal people have been critically reviewed. The results of this review are significant and advantageous in making and execution of prevention and control programme of these blood genetic disorders in tribals of scheduled area of Rajasthan, India.

Various studies have been conducted to therapeutically target CSCs. One of the approaches include is to inhibit cell cycle progression in CSCs. Within last two decades cell cycle and role of various components in its regulation is firmly established. Cell cycle is regulated by Cyclin Dependent Kinases (CDK) bound to cyclin. CDK activity can be blocked by Cyclin-Dependent Kinase Inhibitors (CKIs) which can either bind cyclin/CDK complex or CDK alone and thus stops cell cycle. In this review various studies are discussed that have investigated the therapeutic role of CKIs in eradicating CSCs by inhibiting cell cycle. Overall, the analysis suggests that CKIs could be a potential therapeutic option in controlling CSCs populating in a tumor.","PeriodicalId":94067,"journal":{"name":"Journal of biomedical research & environmental sciences","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89696280","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}
