Despite validated surgical techniques and the development of biomaterials, the procedures aimed at increasing the maxillary bone volume by sinus floor elevation have complications with various degrees of relevance. 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.
尽管经过验证的外科技术和生物材料的发展,旨在通过窦底提升增加上颌骨体积的手术有不同程度的相关并发症。施耐德膜穿孔是进行膜剥离时最常见的事件之一,它可以增加医源性鼻窦炎的风险,损害功能稳态,移植物在窦腔中的分散以及随后手术失败的细菌定植。本报告介绍了一个使用Flusilift(瑞典和Martina, Due Carrare PD)进行跨瓣窦提升的病例,这是一种新型器械,可以使用生理盐水溶液以无创伤的方式将窦底流体动力提升,以分离施耐德膜,而无需使用窦提升器,并使用透明质酸凝胶配方获得足够的牙槽嵴再生,以支持植入物的放置。透明质酸似乎在伤口愈合中起关键作用,并有助于骨再生过程中更快的骨新生。

Background: As the world witnessed the outbreak of coronavirus illness 2019 (COVID-19), a disorder developed as a result of a novel coronavirus, Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), increasing genetics with healthcare evidence suggest a corresponding leadership to SARS as well as the Middle East Respiratory Syndrome (MERS). 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.
背景:随着2019冠状病毒病(COVID-19)的爆发,一种由新型冠状病毒严重急性呼吸综合征冠状病毒2 (SARS- cov -2)引起的疾病,越来越多的遗传学和医疗保健证据表明,SARS和中东呼吸综合征(MERS)相应的领导。目的:综述人体对COVID-19的免疫反应。材料与方法:本研究为叙述性综述。使用PubMed、Google Scholar、Scopus和EMBASE进行全面的文献检索,关键词为:免疫反应;COVID-19;疫苗接种;SARS-Cov-2;ACE2;冠状病毒;即。结果:病毒成分通过鼻孔、嘴巴和眼睛进入人体。SARS-CoV-2比许多流感或冠状病毒更容易继续被忽视。其蛋白可以通过解锁肺细胞中的血管紧张素转换酶2 (ACE2)蛋白来完成进入;病毒也拥有抗原,进一步认识到这些抗原是通过产生抗体来促使免疫活动的。研究人员展示了多种免疫细胞对COVID-19的反应以及有价值的来源检索,发现可能需要通知生产可行的疫苗。结论:人体对病毒感染的自然反应是一种非侵入性的内在反应,其中巨噬细胞、中性粒细胞和树突状细胞限制病毒的进展,甚至可能通过增加症状来预防病毒。这种非侵入性的解决方案伴随着一种弹性反应,在这种反应中,身体产生主要针对疱疹病毒的自由基。

Environmental Health Perspectives on the Emergence and Re-Emergence of Infectious Diseases, Geopolitics and Gain of Function Research 传染病出现和再出现的环境卫生观点,地缘政治和功能研究的收益
Pub Date : 2021-12-01 DOI: 10.37871/jbres1386

Research and publication are relevant from perspectives in the management of local and global health because disease is perspicuously a geopolitical issue ostensibly linked to gain-of-function research where health diplomacy undergirds present and future global functionalities regarding the emergence and reemergence of infectious diseases. These have generated vehement reactions with propensity for extreme geopolitics and gain-of-function natural and anthropogenic activities. Geopolitical parameters and gain-of-function issues impact on the social determinants of health and vice versa. The convening and convergence of countries for unprecedented epidemic or pandemic treaty settings or other formulations to confront emerging and reemerging infectious diseases will afford considerable opportunities concerning challenges in action, preparedness and response. Provisions are pertinent for legal instruments, effective and efficient systems to curb future threats and outbreaks of infectious diseases.
从地方和全球卫生管理的角度来看,研究和出版是相关的,因为疾病显然是一个地缘政治问题,表面上与功能获得研究有关,而卫生外交是当前和未来关于传染病出现和重新出现的全球功能的基础。这些都引发了激烈的反应,并倾向于极端地缘政治和自然和人为活动的功能增益。地缘政治参数和功能获得问题影响健康的社会决定因素,反之亦然。各国召开会议并共同制定前所未有的流行病或大流行病条约或其他方案,以应对新出现和重新出现的传染病,将为行动、准备和应对方面的挑战提供相当大的机会。这些规定与法律文书、有效和高效的制度有关,以遏制未来的威胁和传染病的爆发。

Seismic data acquired in the field show the subsurface reflectors or horizon among the geological strata, while the seismic inversion converts this reflector information into the acoustic impedance section which shows the layer properties based on lithology. The research aims to predict the porosity to identify the reservoir which is in between the tight layer. So, the output of the seismic inversion is much more batter than the seismic as it is closer to reality such as geology. Seismic inversion is frequently used to determine rock physics properties, for example, acoustic impedance and porosity.
现场地震数据显示地质层间的地下反射面或层位,而地震反演将这些反射面信息转换成基于岩性的层性声阻抗剖面。研究的目的是对储层孔隙度进行预测,以识别处于致密层之间的储层。因此,地震反演的结果比地震反演的结果要好得多,因为它更接近地质等实际情况。地震反演经常用于确定岩石的物理性质,例如声阻抗和孔隙度。

Neonatal Sepsis (NS) is a systemic infection caused by bacteria, fungi, or viruses during the first month of life. Although various studies have identified the factors associated with NS, it is a public health problem due to its high morbidity and mortality. The study aimed to identify the risk factors associated with neonatal sepsis in the Neonatal Intensive Care Unit (NICU) of a tertiary hospital in Mexico. A case-control study was carried out using records of neonates (with sepsis 39 and without sepsis 39) from January to December 2017. The risk factors studied were the sociodemographic and clinical characteristics of the mother and clinics of the neonate. The data were analyzed using the Chi2 test, Fisher's exact test, Student's t-test, and the Odds Ratio (OR). The risk factors associated with NS were gestational age (OR 0.77, CI 95% = 0.64-0.91, p = 0.004), newborn weight (OR 0.45, CI95% = 0.23-0.86, p = 0.017) and days of hospital stay (OR 1.06, CI95% = 1.02-1.10, p = 0.0014). The mother's sociodemographic and clinical factors were not associated with NS. Risk factors associated with NS were gestational age, newborn weight, and days of hospital stay.
新生儿败血症(NS)是一种由细菌、真菌或病毒引起的全身性感染,发生在出生后的第一个月。虽然各种研究已经确定了与NS相关的因素,但由于其发病率和死亡率高,它是一个公共卫生问题。该研究旨在确定与墨西哥一家三级医院新生儿重症监护病房(NICU)新生儿败血症相关的危险因素。使用2017年1月至12月的新生儿(脓毒症39和非脓毒症39)记录进行病例对照研究。研究的危险因素是社会人口学和临床特征的母亲和诊所的新生儿。采用Chi2检验、Fisher精确检验、学生t检验和比值比(OR)对数据进行分析。与NS相关的危险因素为胎龄(OR 0.77, CI95% = 0.64-0.91, p = 0.004)、新生儿体重(OR 0.45, CI95% = 0.23-0.86, p = 0.017)和住院天数(OR 1.06, CI95% = 1.02-1.10, p = 0.0014)。母亲的社会人口学和临床因素与NS无关。与NS相关的危险因素有胎龄、新生儿体重和住院天数。

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is an emerging virus responsible for the ongoing Coronavirus Disease 19 (COVID-19) pandemic. 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.
严重急性呼吸综合征冠状病毒2 (SARS-CoV-2)是一种新出现的病毒,导致正在进行的冠状病毒病19 (COVID-19)大流行。尽管出现了COVID-19疫苗,但随着新的SARS-CoV-2变体的出现和全球疫苗短缺的出现,大流行疲劳仍在加剧。因此,药物再利用仍然是对抗SARS-CoV-2的另一种策略。几个世纪以来,植物一直是具有最小细胞毒性和有前景的抗菌和抗病毒活性的药理活性化合物的天然储存库。鉴于此,本研究利用ADME分析对不同品种的33种植物化学物质进行了虚拟筛选,以对抗SARS-CoV-2的主要蛋白酶(Mpro)和Spike (S)蛋白。31种符合Lipinski规则的植物化学物质使用AutoDock Vina进行分子对接。通过选择具有最高亲和力的蛋白质-配体复合物的最佳构象来确定对接分数。研究发现,在hace2结合位点与S蛋白发生高结合能的相互作用。同样地,杨梅三苷、维菊酮、柚皮素、甘草黄酮A和水飞蓟宾与Mpro结构域I和II之间的底物结合袋具有高度的结合亲和力。有趣的是,licoflavone A,水飞蓟宾和withanone在硅中与Mpro和S蛋白相互作用。此外,药物相似性研究表明,在三种候选配体中,威酮是最容易生物利用的植物化学物质。因此,植物化学物质可被视为开发针对这种神秘病毒的抑制剂的潜在线索。体外研究进一步证明其抗病毒功效。

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}

Rajasthan, situated at the north-western part of India is the biggest state in the country of India and has total of 33 districts. 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. Moreover, in this review, research gaps are also highlighted for further research work.
拉贾斯坦邦位于印度西北部,是印度最大的邦,共有33个区。通过合并8个部落主导地区,即班斯瓦拉、奇图尔加尔、登格尔普尔、巴利、普拉塔普加尔、拉贾斯坦邦、西罗希和乌代普尔,政府创建了一个名为“计划区”的特殊地区,其中70%以上的人是部落。这个地区大多是落后和不发达的,疟疾也是高度流行的。在这一地区,Bhil、Damor、Meena、Garasiya、Kathudia和sahara是最主要的内婚部落。除了该地区的几种传染性和非传染性疾病外,某些红细胞遗传性疾病、镰状细胞血红蛋白(Hb-S)、β-地中海贫血和G-6-PD缺乏症(Gd)也使部落的健康状况恶化,并造成他们的发病率和死亡率。这些红细胞遗传性疾病的基因在部落人群中更为普遍和广泛分布。这些血液遗传疾病在部落中的最高患病率分别为31.14%、9.00%和22.00%。由于该部落地区的地下水含有大量氟化物(F),饮用它会使已经具有镰状细胞和β-地中海贫血基因纯合状态的部落人民过早死亡的风险很高。在本通讯中,除了对部落健康的关注外,还对预定地区不同部落族群中镰状细胞血红蛋白、β-地中海贫血和G-6-PD缺乏症基因的状况、这些血液遗传性疾病与疟疾的相关性、F中毒对患有红细胞遗传性疾病的部落受试者的影响以及这些红细胞遗传性疾病在部落人群中的预防和控制进行了严格审查。本综述的结果对印度拉贾斯坦邦规划地区部落这些血液遗传性疾病的预防和控制规划的制定和实施具有重要意义和优势。此外,本文还指出了研究空白,以供进一步研究。

Within a tumor, Cancer Stem Cells (CSCs) exists and own similar characteristics of a normal stem cell thus contributing towards aggressiveness of cancer by playing crucial role in tumor recurrence and metastasis capability. 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.
肿瘤干细胞(Cancer Stem Cells, CSCs)存在于肿瘤中,具有与正常干细胞相似的特性,在肿瘤的复发和转移能力中起着至关重要的作用,从而有助于肿瘤的侵袭性。针对干细胞的治疗靶点已经进行了各种各样的研究。其中一种方法包括抑制干细胞的细胞周期进展。在过去的二十年中,细胞周期和各种成分在其调节中的作用得到了牢固的确立。细胞周期是由与细胞周期蛋白结合的细胞周期蛋白依赖激酶(CDK)调控的。细胞周期蛋白依赖性激酶抑制剂(CKIs)可以阻断CDK活性,CKIs可以结合细胞周期蛋白/CDK复合物或单独结合CDK,从而阻断细胞周期。在这篇综述中,我们讨论了各种研究,探讨了CKIs通过抑制细胞周期来根除CSCs的治疗作用。总的来说,分析表明CKIs可能是控制肿瘤中CSCs填充的潜在治疗选择。
