Do's and Don'ts When Visiting Circularly Polarized Luminescence

Advanced Optical Materials, Volume 14, Issue 11, 20 March 2026.
This perspective presents our insights into the principles, challenges, and opportunities of circularly polarized luminescence (CPL). Highlighting key concepts such as the dissymmetry factor (glum) and molecular design strategies, we discuss advances in CPL efficiency, emerging NIR emitters, solid‐state applications, and the growing role of theory and ...

Molecular epidemiology of carbapenemase-producing Klebsiella pneumoniae in Gauteng South Africa

Scientific Reports
Klebsiella pneumoniae multidrug-resistant (MDR) high-risk clones drive the spread of antimicrobial resistance (AMR) associated infections, resulting in limited therapeutic options. This study described the genomic characteristics of K.

Characterisation of OXA-244, a chromosomally-encoded OXA-48-like β-lactamase from Escherichia coli [PDF]

, 2016
International audienceABSTRACT Shewanella spp. constitute a reservoir of antibiotic resistance determinants. In a bile sample, we identified three extended-spectrum-β-lactamase (ESBL)-producing bacteria ( Escherichia coli , Klebsiella pneumoniae , and ...

Emergence of oxacillinase-181 carbapenemase-producing diarrheagenic Escherichia coli in Ghana

Emerging Microbes and Infections, 2021
The emergence and spread of carbapenemase-producing bacteria are serious threats to public health. We characterized two OXA-181-producing Escherichia coli isolates from pediatric patients with diarrhea from Ghana.

Chromatin Accessibility in Cancer: Biological Functions, Mechanisms, Therapeutic Potential, and Future Directions

MedComm, Volume 7, Issue 3, March 2026.
Cancer remains the leading cause of mortality worldwide, and drug resistance further underscores the urgent need for innovative therapeutic strategies. Chromatin, a stable yet highly dynamic nucleoprotein complex, serves as the primary carrier of genetic material in eukaryotic cells.

Mitophagy and Bip–PERK–eIF2α–ATF4 Axis‐Mediated ER Stress Mediate Miriplatin‐Loaded Liposome's Anti‐Colorectal Cancer Action

Cell Proliferation, Volume 59, Issue 3, March 2026.
LMPt enters the cell mainly through caveolin‐mediated endocytosis, and then fuses with endosomes and lysosomes to deliver MPt to mitochondria and the endoplasmic reticulum to induce mitophagy based on the fusion of lysosomes and mitochondria, and endoplasmic reticulum stress and subsequent apoptosis via the Bip–PERK–eIF2α–ATF4 axis to exert an anti ...

O048: OXA-181- carbapenemase producing Klebsiella pneumoniae: an emerging threat? The first reported nosocomial outbreak in Singapore [PDF]

Antimicrobial Resistance and Infection Control, 2013
Carbapenem-resistant Enterobacteriaceae (CRE) are an emerging global threat. Most outbreaks have been NDM-1 or KPC. We describe an outbreak of OXA-181-producing Klebsiella pneumoniae in a 275 bedded acute general hospital in Singapore.
