Background: The emergence of β-lactamase-producing bacteria limits the effectiveness of β-lactam (BL) antibiotics, and the combination with a β-lactamase inhibitor (BLI) aims to counteract this resistance. However, existing guidelines primarily focus on optimizing the dosing of BLs and do not adequately address the interaction between BLs and BLIs, leading to uncertain pharmacokinetic/pharmacodynamic (PK/PD) targets and potentially suboptimal dosing strategies.

Objectives: To investigate optimal PK/PD targets and dosing strategies for avibactam (BLI) combined with ceftazidime (BL) using mechanism-based PKPD models.

Reduced protein solubility - cause or consequence in amyloid disease?

QRB Discov

February 2025

Biochemistry and Structural Biology, Lund University, Lund, Sweden.

In this perspective, we ask the question whether the apparently lower solubility of specific proteins in amyloid disease is a cause or consequence of the protein deposition seen in such diseases. We focus on Alzheimer's disease and start by reviewing the experimental evidence of disease-associated reduction in the measured concentration of amyloid β peptide, Aβ42, in cerebrospinal fluid. We propose a series of possible physicochemical explanations for these observations.

Modeling for understanding and engineering metabolism.

QRB Discov

February 2025

Department of Life Sciences, Chalmers University of Technology, Gothenburg, Sweden.

Metabolism is at the core of all functions of living cells as it provides Gibbs free energy and building blocks for synthesis of macromolecules, which are necessary for structures, growth, and proliferation. Metabolism is a complex network composed of thousands of reactions catalyzed by enzymes involving many co-factors and metabolites. Traditionally it has been difficult to study metabolism as a whole network and most traditional efforts were therefore focused on specific metabolic pathways, enzymes, and metabolites.

Genotyping by sequencing reveals the genetic diversity and population structure of Peruvian highland maize races.

Front Plant Sci

February 2025

Laboratorio de Genómica y Bioinformática, Universidad Nacional Agraria la Molina (UNALM), Lima, Peru.

Peruvian maize exhibits abundant morphological diversity, with landraces cultivated from sea level (sl) up to 3,500 m above sl. Previous research based on morphological descriptors, defined at least 52 Peruvian maize races, but its genetic diversity and population structure remains largely unknown. Here, we used genotyping-by-sequencing (GBS) to obtain single nucleotide polymorphisms (SNPs) that allow inferring the genetic structure and diversity of 423 maize accessions from the genebank of Universidad Nacional Agraria la Molina (UNALM) and Universidad Nacional Autónoma de Tayacaja (UNAT).

Doping Efficiency of Poly(benzodifurandione) from First Principles.

J Phys Chem C Nanomater Interfaces

March 2025

Institut de Ciència de Materials de Barcelona, ICMAB-CSIC, Campus UAB, 08193 Bellaterra, Spain.

Poly(benzodifurandione) (PBFDO) has emerged as a promising n-type conductive polymer (n-CP) for organic electronic applications, particularly in thermoelectrics (TE), due to its high doping efficiency and environmental stability. Unlike most high-performance p-type polymers, high-efficiency n-CPs are limited, posing a bottleneck in the TE module performance. In this study, we use first-principles electronic structure calculations to investigate the thermodynamic conditions that favor n-doping in PBFDO, focusing on the role of the temperature, chain length, and doping concentration.

Computational tools for the prediction of site- and regioselectivity of organic reactions.

Chem Sci

March 2025

Molecular AI, Discovery Sciences, R&D, AstraZeneca Gothenburg Pepparedsleden 1 43183 Mölndal Sweden

The regio- and site-selectivity of organic reactions is one of the most important aspects when it comes to synthesis planning. Due to that, massive research efforts were invested into computational models for regio- and site-selectivity prediction, and the introduction of machine learning to the chemical sciences within the past decade has added a whole new dimension to these endeavors. This review article walks through the currently available predictive tools for regio- and site-selectivity with a particular focus on machine learning models while being organized along the individual reaction classes of organic chemistry.

For most patients with chronic, progressive illnesses, maintaining good quality of life (QoL), with preserved functional capacity, is just as crucial as prolonging survival. Patients with heart failure (HF) experience much worse QoL and effort intolerance than both the general population and people with other chronic conditions, since they present a range of physical and psychological symptoms, including shortness of breath, chest discomfort, fatigue, fluid congestion, trouble with sleeping, and depression. These symptoms reduce patients' capacity for daily social and physical activity.

[Are we hopefully on the way to eradicating HPV-related cancer?].

Lakartidningen

March 2025

docent, överläkare, dermatologi och venereologi, Karolinska universitetssjukhuset, Stockholm; institutionen för medicin, Karolinska institutet.

An interesting article in this issue of Läkartidningen argues for the benefit of a broad HPV vaccination with catch-up vaccination also for men, and sheds more light on HPV-related cancer in men. There has been an increase of HPV-related anal and oropharyngeal cancer in recent years, but no screening methods for these cancers have been implemented. A gender neutral catch-up vaccination would help to decrease the burden of oncogenic HPV in society, and would also be beneficial for females.

Violence Against Women

March 2025

Department of Social Work, Criminology and Public Health Sciences, University of Gävle, Gävle, Sweden.

This article is based on narratives from 20 women who have experienced domestic violence and abuse (DVA). Based on in-depth interviews, we explored their lived experiences of the mechanisms and meanings of loneliness in the context of DVA. The women experienced social and existential loneliness, not as passive consequences of victimization, but through active isolating and tactics inflicted on them by the abusers, as well as through responses from personal and professional networks and institutions.

Decoding in-plane orientation in cellulose nanopapers hybridized with tailored polymeric nanoparticles.

Nanoscale

March 2025

KTH Royal Institute of Technology, Department of Fiber and Polymer Technology, School of Engineering Sciences in Chemistry, Biotechnology and Health, Teknikringen 56, SE-100 44 Stockholm, Sweden.

Biobased cellulose nanofibrils (CNFs) constitute important building blocks for biomimetic, nanostructured materials, and considerable potential exists in their hybridization with tailorable polymeric nanoparticles. CNFs naturally assemble into oriented, fibrillar structures in their cross-section. This work shows that polymeric nanoparticle additives have the potential to increase or decrease orientation of these cellulose structures, which allows the control of bulk mechanical properties.

At the heart of many nucleoside triphosphatases is a conserved phosphate-binding sequence motif. A current model of early enzyme evolution proposes that this 6-8 residue motif could have sparked the emergence of the very first nucleoside triphosphatases - a striking example of evolutionary continuity from simple beginnings, if true. To test this provocative model, seven disembodied Walker A-derived peptides were extensively computationally characterized.
