Comparative analysis and identification of spike mutations in Iranian COVID-19 samples from the first three waves of disease

Advanced Biomedical Research, 2023
Background: The spike surface glycoprotein of SARS-CoV-2 is the essential protein in virus attachment to the target cell and cell entrance. As this protein contains immunodominant epitopes and is the main target for immune recognition, it is the critical

Caenorhabditis elegans as a model system for studying drug induced mitochondrial toxicity [PDF]

, 2015
Today HIV-1 infection is recognized as a chronic disease with obligatory lifelong treatment to keep viral titers below detectable levels. The continuous intake of antiretroviral drugs however, leads to severe and even life-threatening side effects ...

Molecularly imprinted nanoparticles for inhibiting ribonuclease in reverse transcriptase polymerase chain reaction [PDF]

The Analyst, 2018
We showed that molecularly imprinted nanoparticles (nanoMIPs) could efficiently inhibit the activities of the RNase in RT-PCR reactions, demonstrating that the tailor-made nanomaterials are very promising for use in routine biological assays.

Commercial stocks of SARS-CoV-2 RNA may report low concentration values, leading to artificially increased apparent sensitivity of diagnostic assays [PDF]

, 2020
In response to the rapidly evolving COVID-19 pandemic, the U.S. Food and Drug Administration (FDA) has rapidly issued 49 emergency use authorizations (EUAs) for SARS-CoV-2 in vitro diagnostic test-kits. A critical metric in the performance evaluation for

Fetal Cytokine Expression In UteroDetected by Reverse Transcriptase Polymerase Chain Reaction [PDF]

Pediatric Research, 1995
Cytokine expression at the maternal-fetal interface is well documented. Some authors have postulated the existence of a bidirectional cytokine signaling mechanism that is critical to the maintenance of normal pregnancy. The role of the fetus (versus fetally derived placental tissues) in this process is unknown.

An ultrasensitive reverse transcription polymerase chain reaction assay to detect asymptomatic low-density Plasmodium falciparum and Plasmodium vivax infections in small volume blood samples. [PDF]

, 2015
BackgroundHighly sensitive, scalable diagnostic methods are needed to guide malaria elimination interventions. While traditional microscopy and rapid diagnostic tests (RDTs) are suitable for the diagnosis of symptomatic malaria infection, more sensitive ...
