Autosomal recessive hyper‐IgE syndrome due to DOCK8 deficiency: An adjunctive role for omalizumab

open access: yesJournal of Cutaneous Immunology and Allergy, Volume 5, Issue 6, Page 222-226, December 2022., 2022
We report a rare case of AR‐HIES with DOCK8 deficiency in a young male that was successfully treated by infection management, skincare, diet elimination, and omalizumab. Abstract Autosomal recessive hyper‐IgE syndrome (AR‐HIES) is a rare primary immunodeficiency disorder characterized by high serum IgE levels, recurrent viral skin infections, severe ...

Engineered Probiotics Mitigate Gut Barrier Dysfunction Induced by Nanoplastics

open access: yesAdvanced Science, EarlyView.
Intestinal barrier stability is vital for gut health. Plastic polyethylene terephthalate (PET) disrupts this barrier, causing inflammation and infections. This study encodes transforming growth factor‐β into EcN and modifies its surface with pH‐responsive polymer (EcNT@L), creating an oral drug delivery system to repair nano PET‐induced intestinal ...

Saarvienin A—A Novel Glycopeptide with Potent Activity against Drug‐Resistant Bacteria

open access: yesAngewandte Chemie, EarlyView.
A structurally distinct glycopeptide, saarvienin A, represents a new family of glycopeptide antibiotics consisting of five sugar/aminosugar units connected to a halogenated peptide core. Saarvienin A overcomes vancomycin resistance and shows strong activity against drug‐resistant Gram‐positive bacteria, in particular, high‐priority pathogens such as ...

Recent advances in the characterization of Crl, the unconventional activator of the stress sigma factor σS/RpoS

open access: yesBiomolecular Concepts, 2016
The bacterial RNA polymerase (RNAP) holoenzyme is a multisubunit core enzyme associated with a σ factor that is required for promoter-specific transcription initiation. Besides a primary σ responsible for most of the gene expression during active growth,

Molecular techniques to characterize the invA genes of Salmonella spp. for pathogen inactivation study in composting [PDF]

open access: yesarXiv, 2014
The relatively low concentration of pathogen indicators, such Salmonella, in composting sometimes causes a problem with detection when using the conventional techniques. The presence of viable but non-culturable (VBNC) organisms is also a potential problem with Salmonella detection when using conventional techniques.

Temporal trends in bulk milk antibodies to Salmonella, Neospora caninum, and Leptospira interrogans serovar hardjo in Irish dairy herds [PDF]

open access: yes, 2012
peer-reviewedBulk milk samples were collected from 309 Irish dairy herds at four time points during 2009 and tested for antibodies to Salmonella spp., N. caninum, and L. hardjo, three abortifacient agents in Irish dairy herds. Of the 312 study herds, 49%

Food metabolomics: Latest hardware—developments for nontargeted food authenticity and food safety testing

open access: yesELECTROPHORESIS, Volume 43, Issue 23-24, Page 2334-2350, December 2022., 2022
Abstract The analytical requirements for food testing have increased significantly in recent years. On the one hand, because food fraud is becoming an ever‐greater challenge worldwide, and on the other hand because food safety is often difficult to monitor due to the far‐reaching trade chains.

Serum Neopterin in Differential Diagnosis of Bacterial Diarrhea in Pediatric Patients

open access: yesPteridines, 2019
Background: Neopterin, regarded as a marker of cellular immune activation, has been used in diagnosis of infection caused by intracellular pathogens. We have aimed to evaluate the clinical usefulness of serum neopterin (NPT) in acute bacterial diarrhea ...
