Soon later in January 2020, the Chinese scientists found out a novel category of virus named corona virus, also called as severe acute respiratory syndrome corona virus 2 (SARS-CoV-2; previously known as 2019-nCoV), from these pneumonia patients.1 A new name for this epidemic disease caused by 2019-nCoV was announced by World Health Organization(WHO) on 11th February 2020, as corona virus disease-19 (COVID-19).2Among the chief micro-organisms or pathogens that majorly aim the human respiratory system are the corona virus group of viruses. There also have been previous outbreaks of corona viruses (CoVs) in past years. These include the Middle East respiratory syndrome (MERS)-CoV and the severe acute respiratory syndrome (SARS)-CoV. These outbreaks too have been earlier considered as a reason that caused immense threat to the well-being of society and public life.3 It was believed that the source and initiation of this virus is probably from a zoonotic transmission related with a huge seafood market. There was tradeoff of live animals in these markets too. Soon later it was evident that person-to-person transmission was possible with this virus too. The clinical symptoms associated with SARS-CoV-2 infection shows wide variation of manifestations, ranging from asymptomatic infection (commonly called as the silent carriers), mild upper respiratory tract illness, severe pneumonia, respiratory collapse and even death.1 As per a study conducted by Chen, hospital-associated transmission of this infection was identified to be around 41%.2 Considering rapid increase in incidence rate of SARSCoV-2 infection, transmission by silent carriers & also transmission from human to human, lead it into next pandemic disease. They also studied the microbiological nature of the virus and suggested that it is similar to the corona virus variety circulating in horseshoe bats. Further analysis based on ORF1a/1b, S and N genes proposes that SARS-CoV-2 is possibly a novel corona virus that was autonomously acquainted from animals to humans. Certain investigatory findings suggest that, this infection may have been instigated from bats or bat droppings accompanying with polluted resources in the Wuhan seafood market region.2","PeriodicalId":93110,"journal":{"name":"International journal of molecular biology (Edmond, Okla.)","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79551790","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}

In this study, the antiproliferative activities of Cp₂VCl₂,Cp₂NbCl₂, Cp₂HfCl₂ and Cp₂ZrCl₂were assessed on two human cancer cell lines (HT-29 and MCF-7) using MTT assay. Spectroscopic studies were also conducted using these and other known metallocene dichlorides on apo-human transferrin (apo-hTf) at pH 7.4. UV-Vis and CD showed that their interaction with apo-hTf could induce conformational changes of its secondary structure during binding process. In fluorescence, a decrease in intensity of the emission peak was observed when the apo-hTf:Cp₂M(IV)Cl₂ complex is being formed, probably due to changes in the microenvironment of its tyrosine and tryptophan residues. Among all metallocene dichlorides studied, Cp₂VCl₂ has the strong ability to quench the intrinsic fluorescence of apo-hTf through a static quenching mechanism. The association constants for each protein-compound complex were also determined at different temperatures (296 K, 303 K, 310 K, and 317 K) based on fluorescence quenching results. Positive enthalpy changes (<i>ΔH</i>) and entropy changes (<i>ΔS</i>) as well as negative free energies (<i>ΔG</i>) suggest that hydrophobic interactions are the main intermolecular forces involved in the binding process, probably via an endothermic and spontaneous reaction mechanism. The distance, <i>r</i>, between donor (apo-hTf) and acceptor (Cp₂M(IV)Cl₂) obtained according to Forster's theory of non-radiation energy transfer suggest that the energy transfer from apo-hTf to Cp₂M(IV)Cl₂ occurs with high probability and distances obtained by FRET with high accuracy.</p>","PeriodicalId":93110,"journal":{"name":"International journal of molecular biology (Edmond, Okla.)","volume":"5 3","pages":"79-109"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7668563/pdf/nihms-1641141.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38616193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During childhood, the immune system is physiologically immature, but it develops progressively as the individual grows. Thus, in this period, recurrent infections can occur, mainly in the airways, even in completely healthy children.1,2 Children that born with a defective immune system develop conditions that belong to a group of diseases known as primary immunodeficiencies (PIDs).3–5 These congenital diseases (which develop mainly during childhood) manifest especially in the form of recurrent infections, which often coincide with the immunological maturity period of the patients.6–8 Therefore, recognizing the suggestive characteristics in the clinical history and during the physical examination is fundamental to raise the hypothesis of primary immunodeficiency.3 Given the many characteristics that serve as warning signs, the Jeffrey Modell Foundation in association with the American Red Cross has created a list of Ten Warning Signs to facilitate the medical reasoning during the care of patients who need initial laboratory investigation9 The investigation should be carried out through initial examinations of easy access, which may be requested by the professional in the primary approach.7 The diagnosis should be complemented with specialized examinations in reference centers, where the child should receive prompt treatment.10 An early diagnosis is fundamental for an adequate treatment and consequent improvement in the quality of life of the patient, as well in the long-term prognosis and prevention of sequelae. Therefore, the recognition of the need of a systematic investigation for primary immunodeficiency of the patient depends on a well-founded suspected diagnosis by the physician in the primary approach.","PeriodicalId":93110,"journal":{"name":"International journal of molecular biology (Edmond, Okla.)","volume":"263 3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83702135","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}
