Purpose: Lutetium-177 Prostate-specific membrane antigen (Lu-PSMA) radioligand therapy is EMA-approved for metastatic castration resistant prostate cancer (mCRPC) after androgen receptor pathway inhibition (ARPI) and taxan-based chemotherapy. However, its effect in taxan-naïve patients is under current investigation.

Recently, a distinction has been drawn between conventional false memories, which misrepresent specific facts, and deep distortions, which misrepresent relations that connect facts. We report the first study of adult developmental trends in deep distortions, using a paradigm in which people make conjoint recognition judgments about incompatible facts (e.g.

Photocatalytic Methanol Dehydrogenation with Switchable Selectivity.

J Am Chem Soc

January 2025

Department of Chemistry, University of California, Berkeley, California 94720, United States.

Switchable selectivity achieved by altering reaction conditions within the same photocatalytic system offers great advantages for sustainable chemical transformations and renewable energy conversion. In this study, we investigate an efficient photocatalytic methanol dehydrogenation with controlled selectivity by varying the concentration of nickel cocatalyst, using zinc indium sulfide nanocrystals as a semiconductor photocatalyst, which enables the production of either formaldehyde or ethylene glycol with high selectivity. Control experiments revealed that formaldehyde is initially generated and can either serve as a terminal product or intermediate in producing ethylene glycol, depending on the nickel concentration in the solution.

J Antimicrob Chemother

January 2025

Division of Infectious Diseases, Faculty of Medicine and University Hospital Cologne, Department I of Internal Medicine, University of Cologne, Kerpener Str. 62, 50939 Cologne, Germany.

Background: Persistent COVID-19 (pCOVID-19) in immunocompromised patients is characterized by unspecific symptoms and pulmonary infiltrates due to ongoing severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) replication. Treatment options remain unclear, leading to different approaches, including combination therapy and extended durations. The purpose of this study was to assess the efficacy and safety of antiviral therapies for pCOVID-19 in immunocompromised patients since the Omicron surge.

NiMnZ (Z = In, Sn or Sb) undergo martensitic transformation with transformation temperature () scaling with the average valence electron per atom (/) ratio. However, the rate of increase of depends on the type of Z atom, with the slope of / curve increasing from Z = In to Z = Sb. Local structural distortions are believed to be the leading cause of martensitic transformation in these alloys.

We present the synthesis, characterization, and photophysical properties of two pyrene-modified () pincer bismuth complexes, where the pyrenyl residues are either part of the cyclometalating pincer ligand (1) or bound as monodentate ligands to the Bi ion (2). Both complexes are dually emissive at 77 K. For complex 2, pyrenyl phosphorescence persists at r.

Microgels are versatile materials with applications across biomedicine, materials science, and beyond. Their controllable size and composition enables tailoring specific properties, yet characterizing their internal structures on the nanoscale remains challenging. Super-resolution fluorescence microscopy (SRFM) effectively analyzes sub-μm structures, including microgels, offering a tool for investigating more complex systems such as core-shell microgels.

Aims: The gastrointestinal (GI) tract is composed of distinct sub-regions, which exhibit segment-specific differences in microbial colonization and (patho)physiological characteristics. Gut microbes can be collectively considered as an active endocrine organ. Microbes produce metabolites, which can be taken up by the host and can actively communicate with the immune cells in the gut lamina propria with consequences for cardiovascular health.

Chronic pain is a prevalent and debilitating condition whose neural mechanisms are incompletely understood. An imbalance of cerebral excitation and inhibition (E/I), particularly in the medial prefrontal cortex (mPFC), is believed to represent a crucial mechanism in the development and maintenance of chronic pain. Thus, identifying a non-invasive, scalable marker of E/I could provide valuable insights into the neural mechanisms of chronic pain and aid in developing clinically useful biomarkers.

DNA methyltransferase and poly (ADP-ribose) polymerase inhibitors (DNMTis, PARPis) induce a stimulator of interferon genes (STING)-dependent pathogen mimicry response (PMR) in ovarian and other cancers. Here, we showed that combining DNMTis and PARPis upregulates expression of the nucleic-acid sensor NFX1-type zinc finger-containing 1 protein (ZNFX1). ZNFX1 mediated induction of PMR in mitochondria, serving as a gateway for STING-dependent interferon/inflammasome signaling.

Compared to aziridines, azaphosphiridines, which formally result from the replacement of a carbon atom by phosphorus, have been much less studied. In this work, accurate values for one of the most prominent properties, the ring strain energy (RSE), have been theoretically examined for a wide range of azaphosphiridine derivatives. Strongly related aspects of interest for developing the use of azaphosphiridines in heteroatom and polymer chemistry are ring opening reactions and polymerisations, the latter facilitated by their significantly high RSE.

Calcium supplementation before exercise attenuates the decrease in serum calcium and increase in PTH and bone resorption. This study investigated the effect of calcium supplementation on calcium and bone metabolism during load carriage in women. Forty-eight women completed two load carriage sessions (load carriage 1 n = 48; load carriage 2 n = 40) (12.

Magnesium-containing molecules, including MgCH, MgCH, and MgCH, have been detected in the interstellar medium, largely facilitated by their high dipole moments. However, despite great efforts, MgCH species remain elusive. Given the challenges in obtaining experimental data for these molecules, theoretical studies play a crucial role in guiding their detection.

Target odorant detection in mixtures has been shown to become more difficult as the number of background odorants increases and falls below chance level in mixtures with 16 components. Our aim was to investigate target odorant detection in mixtures among healthy people and compare it between dysosmic patients and age- and gender-matched controls. Participants underwent extensive olfactory testing and performed two target odorant detection tasks.

Toward Grid-Based Models for Molecular Association.

J Chem Theory Comput

January 2025

Department of Biology, Chemistry and Pharmacy, Freie Universität Berlin, Arnimallee 22, 14195 Berlin, Germany.

This paper presents a grid-based approach to model molecular association processes as an alternative to sampling-based Markov models. Our method discretizes the six-dimensional space of relative translation and orientation into grid cells. By discretizing the Fokker-Planck operator governing the system dynamics via the square-root approximation, we derive analytical expressions for the transition rate constants between grid cells.

Introduction: Long-term fasting (LF) activates an adaptative response to switch metabolic fuels from food glucose to lipids stored in adipose tissues. The increase in free fatty acid (FFA) oxidation during fasting triggers health benefits. We questioned if the changes in lipid metabolism during LF could affect lipids in cell membranes in humans.

Identification of a Chemical Probe for BLT2 Activation by Scaffold Hopping.

J Med Chem

January 2025

Fraunhofer Institute for Translational Medicine and Pharmacology ITMP, and Fraunhofer Cluster of Excellence Immune-Mediated Diseases CIMD, Theodor-Stern-Kai 7, Frankfurt am Main 60596, Germany.

The leukotriene B4 receptor 2 (BLT2) is a G-protein coupled receptor, which is endogenously activated by 12()-hydroxyheptadeca-5Z,8E,10E-trienoic acid (12-HHT). BLT2 is gaining attention as a potential therapeutic target involved in various pathologies including diabetic wound healing, ophthalmic diseases, and colitis. However, validation of BLT2 as drug target requires chemical probes and pharmacological tools which will allow for application in vivo.

We synthesized and spectroscopically investigated monolayer (ML) C on the topological insulator (TI) BiTe. This C/BiTe heterostructure is characterized by an excellent translational order in a novel (4 × 4) C superstructure on a (9 × 9) cell of BiTe. Angle-resolved photoemission spectroscopy (ARPES) of C/BiTe reveals that ML C accepts electrons from the TI at room temperature, but no charge transfer occurs at low temperatures.
