The human nervous system is complex and shows variability in cell types. It includes neurons (functional components), glial cells (supporting cells), astrocytes (provide nourishment), oligodendrocytes (synthesize myelin sheath), and microglia (defense mechanism). To understand the functional and disease states of the nervous system, it is essential to investigate them at the single-cell level. It has been estimated that every 1 in 9 people is affected by mental or neurological disorders, including psychological disorders (generally referred to as mental disorders), psychotic disorders (involving psychosis), and neurological disorders (involving neurological factors), globally. These disorders have multifactorial etiology and are caused by genetic and environmental factors. Every disorder has distinct pathophysiology affecting multiple brain regions. SCO has excellent potential to provide insight regarding the diagnosis, pathophysiology, and treatment of neurological disorders. The stringent well directed SCO methods enhance the understanding of complex nervous system disorders, such as meningitis, stroke, schizophrenia, Parkinson’s disease, and Alzheimer’s disease, which paves the way for future research.","PeriodicalId":271898,"journal":{"name":"Current Trends in OMICS","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126792631","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 occurs due to two mutations in the HBB gene located on chromosome 11. This gene has 1606 base pairs and contains three exons. Moreover, HBB gene codes for β globin protein have been identified to posses 868 mutations, which comprise point mutation, insertion, deletion, and gene arrangement. In β thalassemia major, both alleles are mutated and no β chain is synthesized. In this study, three human families with thalassemia were selectedfrom different areas of Balochistan. For DNA extraction and estimation, 5 ml blood samples were extracted intravenously from the affected individuals, their normal siblings, and parents in 15ml falcon tubes containing 200μl EDTA. Primer sequences were designed on primer 3 for the mutational analysis of the HBB gene. Since the gene has a total of three exons and two introns, three primers, namely HBBX1, HBBX2 and HBBX3, were designed. These primers were used to amplify the HBB gene responsible for β thalassemia in all family samples. The amplified product was sequenced through an automated 3100 ABI Prism DNA sequence. The sequencing results were analyzed by the SaqMan software. This was done to determine if any genetic variable in the selected families showed mutations. In Family 1, 1 bp substitution mutation (c.9T>C) (p.his3his) and 1bp insertion (c.111T>G) (p.Ser10 val) in exon 1 of HBB gene were identified in thalassemia locus, while in in Family 2, 1bp substitution mutation (c.9T>C) (p.His3His) in exon 1 of HBB gene was identified in thalassemia locus. No mutation was observed in Family 03after sequencing.","PeriodicalId":271898,"journal":{"name":"Current Trends in OMICS","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134184234","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}

Globally, every nine individuals out of 100,000 are diagnosed with this cancer. Basic risk factors of meningioma comprise ionizing radiation, hormonal imbalance, and genetic aberrations. In this study, various bioinformatics tools, specialized for consensus-based identification, sequence-homology, and supervised learning, were employed to analyze and screen the deleterious mutational landscape of commonly associated genes of meningioma/genes commonly associated with meningioma. This study employed an in-silico approach aimed to utilize thirteen different tools to benchmark pathogenic single nucleotide polymorphisms (SNPs) in SMARCB1, AKT1, SMO, SUFU, NF2 and MTHFR genes related to meningioma. We identified six highly pathogenic SNPs related to meningioma: SMARCB1 (rs387906812, rs387906811, rs267607072), AKT1 (rs121434592), SMO (rs121918347), and SUFU (rs202247756). Additionally, several deleterious missense variants of NF2 and MTHFR genes were also identified. Hence, this study is a gateway for research on SNPs since they can be utilized to conduct a type-based diagnosis of meningioma for its early prognosis. They can also be utilized as genomic targets for a targeted therapy by developing inhibitors against mutated proteins. For this purpose, further wet-lab experiments and genome-wide association studies are required to genotype these SNPs in a large number of samples, collected from different populations belonging to various ethnicities, for the development of SNP(s) gene panels.","PeriodicalId":271898,"journal":{"name":"Current Trends in OMICS","volume":"289 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133631268","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}

However, this crop is susceptible to different biotic and abiotic factors, which can affect its crop yield. This vulnerability can be reduced or eliminated by growing potatoes under sterilized conditions. Cytokinins, such as 6-Benzylaminopurine, are proven to show a significant role in the in vitro regulation of plants. In the current study, explants of Kuroda variety were/potato cv. Kuroda were grown using diverse concentrations of 6-Benzylaminopurine (BAP), which displayed varied results. BAP concentration of 0.01 mg/l showed a 10 cm shoot length with 41 shoots having 66.66% regeneration efficiency. Meanwhile, the explant grown in 0.25 mg/l BAP concentration showed 16 cm shoot length with 65 shoots having 83.33% regeneration efficiency. On the other hand, the explants that were grown using 0.05 mg/l and 1 mg/l BAP concentration showed 7 cm and 10 cm shoot length with 35 and 52 shoots having 63.33% and 76.66% regeneration efficiency, respectively. Therefore, it was concluded that 0.25 mg/L of BAP showed the best results with the highest number of shoots and shoot length as well as maximum regeneration efficiency among all the tested concentrations.","PeriodicalId":271898,"journal":{"name":"Current Trends in OMICS","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128514412","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}

There have been several coronaviruses induced epidemics such as severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) in the recent past. More recently, another coronavirus-induced disease, namely COVID-19 emerged as an epidemic and rapidly developed into a pandemic due to the high transmissibility of SARS-CoV-2. It emerged as an epidemic novel COVID-19, in late 2019, instigated by SARS-CoV2. This review analyses the different aspects of SARS-CoV-2 including its genomic structure, protein composition, transmission mode, and life cycle. SARS-CoV-2 is an RNA virus, which codes four structural proteins along with various accessory proteins. A unique property of COVID-19 is that it incorporates a polybasic cleavage site, which increases its pathogenicity. The genomic variation of COVID-19/SARS-CoV-2 is assumed to be the reason behind its high transmissibility. It was identified that this genomic variation hinders the development of treatment against this disease. This review aims to facilitate the prevention of this infectious disease as well as suggest possible treatment regimens.","PeriodicalId":271898,"journal":{"name":"Current Trends in OMICS","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115158378","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 high throughput technologies collectively called as omics revolutionized medical research in the last two decades. The advent of next generation sequencing (NGS) reduced the time and economic cost of traditional sequencing and has led to the emergence of genomics as the first discipline of omics. Following the emergence of genomics, a number of projects such as The Cancer Genome Atlas (TCGA), 1000 Genome Project (1KGP), and the International Cancer Genome Consortium have been accomplished. These projects contributed significantly to the understanding of genetic variations in different cancers, for instance, TCGA produced over 2.5 petabytes of big data. Furthermore, the big data produced by these mega projects has been made publicly available to the clinicians and researchers to fast-track the diagnosis and prognosis of complex rare diseases. In developed countries, a multi-omics approach has been applied holistically to the clinical practice for the diagnosis and prognosis of various cancers and rare Mendelian diseases.","PeriodicalId":271898,"journal":{"name":"Current Trends in OMICS","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130072497","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}

One of the most common public databases used for biological sequence retrieval is GenBank which is a comprehensive public database of nucleotide sequences. However, as the length of the sequence to be retrieved increases such as a chromosome, entire genome, scaffold, etc., the elapsed time to download the file gets even elongated due to slower bandwidth to download/retrieve the sequence.[8] In most cases, during sequence analysis, the researcher requires messenger RNA (mRNA), RNA, DNA, protein sequences of the same sequence-of-interest to work with, which consumes a substantial amount of the researcher in finding and retrieving the sequence files. An access to GenBank through JAVA HTTPS protocols is established to request and receive the sequence files associated with the input accessions. SeqDown was shown to be much efficient in terms of retrieval time of the sequences as compared to the other internet browsers and was found to be 15.27% faster than Mozilla Firefox. SeqDown also provides the feature to retrieve coding DNA sequences & protein sequences present in a single chromosome. Sequence retrieval from the most biological databases don’t have proper naming of their files and the user has to deal with the redundantly named sequence files which leads to incorrect and time-consuming analysis and can be solved with SeqDown.
