Article Synopsis
  • The study investigates the emergence of the β-hemolytic pathogen SDSE in humans, particularly in Germany, where there has been limited research into its pathogenicity.
  • It combines national surveillance data and a clinical study to analyze factors like infection type, resistance, patient demographics, and disease severity over a 12-year period.
  • Findings indicate a rising incidence of invasive SDSE infections, with specific types becoming more prevalent and suggesting a mutation-driven outbreak, while age and sex also influenced infection patterns and severity.

Attachment narratives are increasingly used as a diagnostic tool in the therapeutic work with children in middle childhood. This, however, demands extensive procedures to ensure its adequate analysis and reliability.Thus, a new diagnostic instrument has been developed.

Chemically fueled supramolecular materials offer unique properties that include spatial and temporal control and even the ability to self-heal. Indeed, a few studies have demonstrated the ability to self-heal, however, the underlying mechanisms remain unclear. Here, we designed a peptide that forms a fibrillar network upon chemical fueling.

Article Synopsis
  • The ability to store information in chemical reaction networks underpins the complexities of life and cellular memory, allowing states to switch between on and off through transient signals.
  • Synthetic memory circuits have been created through genetic rewiring and designing reaction networks, but small molecule-based alternatives remain challenging.
  • This study demonstrates a bistable system using a non-equilibrium reaction cycle linked to crystallization, allowing for volatile memory storage and practical applications like a matrix display for images and an OR-gate for logic operations.

Methyl groups can have profound effects in drug discovery but the underlying mechanisms are diverse and incompletely understood. Here we report the stereospecific effect of a single, solvent-exposed methyl group in bicyclic [4.3.

Previously it was shown that application of probiotics stopped the acquisition of vancomycin-resistant (VRE) by patients in an early rehabilitation ward. Once the application of probiotics ended, we examined whether acquisition of VRE reoccurred. Furthermore, we examined whether probiotics altered prevalence of vancomycin-susceptible (VSE) and Gram-negative bacteria, which produce extended spectrum beta-lactamase (ESBL).

Purpose: According to the WHO vancomycin-resistant (VRE) belongs to the microorganisms for which new antibiotics are urgently needed. Depending on the type of vancomycin resistance A gene VRE is differentiated from B VRE and other types. In this retrospective analysis the results of VRE surveillance performed at a German tertiary hospital with approximately 1,200 beds between 2013 and 2017 are shown.

Dissipative self-assembly is a process in which energy-consuming chemical reaction networks drive the assembly of molecules. Prominent examples from biology include the GTP-fueled microtubule and ATP-driven actin assembly. Pattern formation and oscillatory behavior are some of the unique properties of the emerging assemblies.

Life is a dissipative nonequilibrium structure that requires constant consumption of energy to sustain itself. How such an unstable state could have selected from an abiotic pool of molecules remains a mystery. Here we show that liquid phase-separation offers a mechanism for the selection of dissipative products from a library of reacting molecules.

FK506-binding proteins (FKBPs) are evolutionarily conserved proteins that display peptidyl-prolyl isomerase activities and act as coreceptors for immunosuppressants. Microbial macrophage-infectivity-potentiator (Mip)-type FKBPs can enhance infectivity. However, developing druglike ligands for FKBPs or Mips has proven difficult, and many FKBPs and Mips still lack biologically useful ligands.

Purpose: In January 2015, we noticed by rectal swab analyses that seven of 23 patients at an early rehabilitation ward had been colonized with carbapenem-resistant Klebsiella pneumoniae (CKP). Here, we describe risk factors for CKP acquisition.

Methods: In the present study, the outbreak is described and risk factors for CKP acquisition are examined, e.

Many biological materials exist in non-equilibrium states driven by the irreversible consumption of high-energy molecules like ATP or GTP. These energy-dissipating structures are governed by kinetics and are thus endowed with unique properties including spatiotemporal control over their presence. Here we show man-made equivalents of materials driven by the consumption of high-energy molecules and explore their unique properties.

A 9-year-old girl was severely injured in a car accident in Afghanistan, in which both her lower legs were badly damaged. She was treated at the Hospital of Ingolstadt (Klinikum Ingolstadt) after she had undergone initial surgery at an Indian hospital. Various bacterial species were isolated from multiple wounds, and methicillin-resistant Staphylococcus aureus (MRSA) was one among them.
