Structural Basis of Shiga Toxin Neutralization by Human Antibodies Targeting Canonical Receptor‐Binding and Non‐Canonical Assembly Sites

Advanced Science, EarlyView.
Cryo‐electron microscopy structures reveal two distinct neutralization mechanisms of fully human monoclonal antibodies targeting the Shiga toxin 1a B subunit. RDS059 occludes the Gb3 receptor‐binding site, whereas RDS045 engages a lateral quaternary epitope to disrupt holotoxin assembly.

Detection of human herpesvirus-7 by qualitative nested-PCR: comparison between healthy individuals and liver transplant recipients Detecção de herpesvirus humano-7 por nested-PCR qualitativo: comparação entre indivíduos sadios e receptores de transplante hepático

Revista da Sociedade Brasileira de Medicina Tropical, 2008
Diagnosis of human herpesvirus-7 active infection in transplant patients has proved difficult, because this virus is ubiquitous and can cause persistent infections in the host.

Detection of Candida albicans by Nested PCR

Journal of the Japanese Association for Infectious Diseases, 1994
A nested PCR assay was developed for the diagnosis of Candida albicans infection. A segment of the C. albicans beta-tubulin gene was amplified in this assay that was sensitive with the detection limit of 10 fg DNA of C. albicans. This assay was found to be specific by obtaining the negative results with 13 organisms (5 other Candida, 2 Cryptococcus, 3 ...

Early Spatial and Contextual Coding Deficits in Hippocampal CA1 Precede Performance Decline in an Alzheimer's Disease Model

Advanced Science, EarlyView.
Two‐photon calcium imaging in behaving 5xFAD mice reveals early CA1 coding deficits before behavioral decline. Task‐related place cell activity and splitter cell trajectory coding are impaired, with reduced retrospective dominance and greater prospective weighting.

Rapid diagnosis of coccidioidomycosis by nested PCR assay of sputum [PDF]

Clinical Microbiology and Infection, 2007
Coccidioidomycosis is a deep infection caused by two dimorphic fungi, Coccidioides immitis and Coccidioides posadasii. Diagnosis of the disease requires culture of suspicious clinical samples on mycological media. However, as these species are virulent pathogens, handling of their cultures is a high-risk activity, and is limited to Biosafety Level 3 ...

Cancer‐Associated Fibroblasts Promote Glucose Metabolic Reprogramming and Progression of Triple‐Negative Breast Cancer via Exosomal circFAD104‐Mediated Intercellular Communication

Advanced Science, EarlyView.
CAF‐derived exosomes deliver circFAD104 into TNBC cells, where it acts as a molecular scaffold that bridges the E3 ligase MARCHF8 and PGM1, promoting MARCHF8‐mediated K48‐linked ubiquitination and proteasomal degradation of PGM1. Loss of PGM1 redirects glucose‐phosphate flux from glycogen synthesis toward glycolysis, thereby driving stemness, EMT, and ...

Evaluation of Group specific Nested PCR for detection of Bluetongue virus [PDF]

Veterinary World, 2009
During the present study RT-PCR and nested PCR was evaluated for the detection of BTV in blood samples collected from suspected cases of bluetongue. Due to conserved nature, NS1 gene was targeted for the development of partial length and nested PCR assay.
