The 1- and 5-year patient and graft survival rates of pediatric kidney transplant recipients have improved considerably in recent years. Regardless of early success, kidney transplantation is challenged by suboptimal long-term allograft and patient survival. Many kidney transplants are lost due to immune (rejection) and nonimmune allograft injuries, and patient survival is limited from cardiovascular disease, infection, and malignancy.

Corrinoids are cobalt-containing tetrapyrroles. They include adenosylcobalamin (vitamin B) and cobamides that function as cofactors and coenzymes for methyl transfer, radical-dependent and redox reactions. Though cobamides are the most complex cofactors in nature, they are essential in the acetyl-CoA pathway, thought to be the most ancient CO-fixation pathway, where they perform a pterin-to-cobalt-to-nickel methyl transfer reaction catalyzed by the corrinoid iron-sulphur protein (CoFeS).

Photoisomerization Dynamics of Azo-Escitalopram Using Surface Hopping and a Semiempirical Method.

J Phys Chem B

January 2025

Institute of Theoretical Chemistry, Faculty of Chemistry, University of Vienna, Währinger Str. 17, 1090 Vienna, Austria.

The photoisomerization dynamics of azo-escitalopram, a synthetic photoswitchable inhibitor of the human serotonin transporter, is investigated in both gas-phase and water. We use the trajectory surface hopping method─as implemented in SHARC─interfaced with the floating occupation molecular orbital-configuration interaction semiempirical method to calculate on-the-fly energies, forces, and couplings. The inclusion of explicit water molecules is enabled using an electrostatic quantum mechanics/molecular mechanics framework.

pH-FISH: coupled microscale analysis of microbial identity and acid-base metabolism in complex biofilm samples.

Microbiome

December 2024

Section for Oral Ecology, Cariology, Department of Dentistry and Oral Health, Aarhus University, Vennelyst Boulevard 9, 8000, Aarhus C, Denmark.

Background: Correlative structural and chemical imaging of biofilms allows for the combined analysis of microbial identity and metabolism at the microscale. Here, we developed pH-FISH, a method that combines pH ratiometry with fluorescence in situ hybridization (FISH) in structurally intact biofilms for the coupled investigation of microbial acid metabolism and biofilm composition. Careful biofilm handling and modified sample preparation procedures for FISH allowed preservation of the three-dimensional biofilm structure throughout all processing and imaging steps.

Addressing treatment switching in the ALTA-1L trial with g-methods: exploring the impact of model specification.

BMC Med Res Methodol

December 2024

Institute for Medical Information Processing, Biometry, and Epidemiology (IBE), Faculty of Medicine, Ludwig-Maximilians-Universität München, Marchioninistr. 15, 81377, Munich, Germany.

Article Synopsis
  • Treatment switching in clinical trials complicates causal inference, making intention-to-treat (ITT) analyses less reliable for determining the true treatment effect.
  • The ALTA-1L trial on brigatinib versus crizotinib highlighted this issue, showing more promising results for brigatinib when removed from treatment switching scenarios, via methods like Inverse Probability of Censoring Weights (IPCW).
  • Re-analysis using IPCW and g-methods suggested that the treatment effect of brigatinib on overall survival may be significantly better than previously estimated, indicating that standard ITT analysis might underestimate treatment benefits.

Anti-IgLON5 disease was identified 10 years ago, thanks to the discovery of IgLON5 antibodies and the joint effort of specialists in sleep medicine, neuroimmunology, and neuropathology. Without this collaboration, it would have been impossible to untangle fundamental aspects of this disease. After the seminal description in 2014, today there is growing evidence that most patients present a chronic progressive course with gait instability, abnormal movements, bulbar dysfunction, and a sleep disorder characterized by nonrapid eye movement and REM parasomnias, and obstructive sleep apnea with stridor.
