SARS-CoV-2 vaccination elicits unconventional IgM specific responses in naïve and previously COVID-19-infected individuals

 Currently, evaluation of the IgG antibodies specific for the SARS-CoV-2 Spike protein following vaccination is used worldwide to estimate vaccine response. Limited data are available on vaccine-elicited IgM antibodies and their potential implication in immunity to SARS-CoV-2.  We Bio Med Frontiers performed a longitudinal study to quantify anti-S SARS-CoV-2 IgG and IgM (IgG-S and IgM-S) in health care worker … Read more

Next Generation Sequencing Reveals a Synchronous Trilateral Lung Adenocarcinoma Case with Distinct Driver Alterations of EGFR 19 Deletion or EGFR 20 Insertion or EZR-ROS1 Fusion

Next Generation Sequencing Reveals a Synchronous Trilateral Lung Adenocarcinoma Case with Distinct Driver Alterations of EGFR 19 Deletion or EGFR 20 Insertion or EZR-ROS1 Fusion

Goal: Synchronous a number of main lung most cancers (SMPLC) has a reported incidence from 0.5% to 2% in lung most cancers, and the surgical remedy and prognosis had been fairly numerous. With the invention of driver mutations in lung adenocarcinoma (ADC), next-generation sequencing (NGS) would offer an specific reply to the important thing query, whether … Read more

A highly sensitive method for the detection of recombinant PERV-A/C env RNA using next generation sequencing technologies

A highly sensitive method for the detection of recombinant PERV-A/C env RNA using next generation sequencing technologies

A number of xenogenic cell-based therapeutic merchandise are at present beneath improvement around the globe for the therapy of human illnesses. Porcine islet cell merchandise for treating human diabetes are a typical instance. Since porcine cells possess endogenous retrovirus (PERV), which may replicate in human cells in vitro, the potential transmission of PERV has raised … Read more

Next-generation Sequencing of Cerebrospinal Fluid for the Diagnosis of Unexplained Central Nervous System Infections

Next-generation Sequencing of Cerebrospinal Fluid for the Diagnosis of Unexplained Central Nervous System Infections

Background: Central nervous system infections trigger important morbidity and mortality in pediatric sufferers. Nevertheless, in roughly half of the scientific circumstances, the etiology is unidentified. As an unbiased molecular diagnostic know-how, next-generation sequencing is steadily being utilized to analyze central nervous system infections. This evaluate summarizes and critiques the literature on this new know-how for etiologic … Read more

Assessment of Minimal Residual Disease by Next Generation Sequencing in Peripheral Blood as a Complementary Tool for Personalized Transplant Monitoring in Myeloid Neoplasms

Assessment of Minimal Residual Disease by Next Generation Sequencing in Peripheral Blood as a Complementary Tool for Personalized Transplant Monitoring in Myeloid Neoplasms

Sufferers with myeloid neoplasms who relapsed after allogenic hematopoietic stem cell transplant (HSCT) have poor prognosis. Monitoring of chimerism and particular molecular markers as a surrogate measure of relapse isn’t all the time useful; subsequently, improved techniques to detect early relapse are wanted. We hypothesized that the usage of subsequent technology sequencing (NGS) may very … Read more

Clinical application and evaluation of metagenomic next-generation sequencing in suspected adult central nervous system infection.

accurate etiologic diagnosis is essential for infection of the central nervous system (CNS infections). The diagnostic value of metagenomic sequencing generation (mNGS), a powerful platform that appears, remains to be studied in the CNS infections.We conduct a prospective cohort study comparing single-center for mNGS with conventional methods including culture, smear and others 248 suspected CNS infectious patients were enrolled and clinical data were recorded. RESULTS mNGS reported a sensitivity of 90.00% (9/10) in patients with culture-positive without empirical treatment and 66.67% (6/9) in patients treated empirically. Detected addition of 48 bacteria and fungi in culture-negative patients, mNGS provide higher detection rate compared with culture in patients with (34.45% vs. 7.56%, McNemar test, p 0.0083). Compared with the conventional method, the positive percent agreement and negative percent agreement was 75.00% and 69.11% separately. mNGS detection rate was significantly higher in patients with cerebrospinal fluid (CSF) WBC> 300 * 106 / L, CSF protein> 500 mg / L or glucose ratio ≤ 0.3. mNGS sequencing reads correlated with CSF WBC, the ratio of glucose and the development of clinical disease. mNGS showed satisfactory diagnostic performance in CNS infections and has a superior detection rate overall culture. mNGS probably held diagnostic benefit, especially in patients treated empirically. CSF laboratory results are statistically relevant mNGS detection rate, and mNGS can dynamically monitor the progression of the disease.
