Aggregative adherent strains of Corynebacterium pseudodiphtheriticum enter and survive within HEp-2 epithelial cells

Memorias do Instituto Oswaldo Cruz, 2012
Corynebacterium pseudodiphtheriticum is a well-known human pathogen that mainly causes respiratory disease and is associated with high mortality in compromised hosts. Little is known about the virulence factors and pathogenesis of C. pseudodiphtheriticum.

Deep Active Learning for Automatic Mitotic Cell Detection on HEp-2 Specimen Medical Images

Diagnostics, 2023
Identifying Human Epithelial Type 2 (HEp-2) mitotic cells is a crucial procedure in anti-nuclear antibodies (ANAs) testing, which is the standard protocol for detecting connective tissue diseases (CTD). Due to the low throughput and labor-subjectivity of

QCD Effects in the Decays of TeV Black Holes [PDF]

, 2006
In models with ``large'' and/or warped extra dimensions, the higher-dimensional Planck scale may be as low as a TeV. In that case black holes with masses of a few TeV are expected to be produced copiously in multi-TeV collisions, in particular at the LHC.

Antisense oligodeoxynucleotides targeting ATM strengthen apoptosis of laryngeal squamous cell carcinoma grown in nude mice

Journal of Experimental & Clinical Cancer Research, 2011
Background To conserve laryngeal function and elevate living quality of laryngeal squamous cell carcinoma (LSCC) patients, we designed antisense oligodeoxynucleotides (AS-ODNs) to reduce expression of ATM and to enhance the apoptosis of hep-2 (Human ...

Osteopontin plays a pivotal role in increasing severity of respiratory syncytial virus infection. [PDF]

PLoS ONE, 2018
The molecular mechanisms underlying susceptibility to severe respiratory syncytial virus (RSV) infection remain poorly understood. Herein, we report on the role of osteopontin (OPN) in regulation of RSV infection in human epithelial cells and how ...

Natural and synthetic antimicrobials reduce adherence of enteroaggregative and enterohemorrhagic Escherichia coli to epithelial cells.

PLoS ONE, 2021
Adherence of bacteria to the human intestinal mucosa can facilitate their internalization and the development of pathological processes. Escherichia coli O104:H4 is considered a hybrid strain (enteroaggregative hemorrhagic E.

Diferenças nas propriedades adesivas de Staphylococcus saprophyticus a células HEp-2 e eritrócitos Differences on the adhesive property of Staphylococcus saprophyticus to HEp-2 cells and erythrocytes

Revista do Instituto de Medicina Tropical de São Paulo, 1992
S. saprophyticus é freqüentemente isolado de infecções do trato urinário de mulheres jovens e sexualmente ativas. Ao contrário de S. aureus, esta espécie não possui fatores de virulência bem definidos. O objetivo deste estudo é analisar a aderência de S.
