Decades of research have shown that adversity tends to be associated with lower working memory (WM) performance. This literature has mainly focused on impairments in the capacity to hold information available in WM for further processing. However, some recent adaptation-based studies suggest that certain types of adversity can leave intact, or even enhance, the ability to rapidly update information in WM.

Background: Dropout from healthcare interventions can negatively affect patients and healthcare providers through impaired trust in the healthcare system and ineffective use of resources. Research on this topic is still largely missing on refugees and asylum seekers. The current study aimed to characterize predictors for dropout in the Mental Health in Refugees and Asylum Seekers (MEHIRA) study, one of the largest multicentered controlled trials investigating the effectiveness and cost-effectiveness of a nationwide stepped and collaborative care model.

Association of Osteoporosis with Tooth Loss and Dental Radiomorphometric Indices.

Biomedicines

December 2024

Department of Periodontology and Operative Dentistry, University Medical Center, University of Mainz, 55131 Mainz, Germany.

Osteoporosis is a systemic disease associated with reduced bone mass, impaired bone microarchitecture, and thus an increased risk of bone fractures. Moreover, patients with osteoporosis are more likely to experience periodontal diseases and tooth loss. Some indices have been proposed to detect osteoporosis on dental panoramic radiographs.

Schizophrenia (SCZ), bipolar (BD) and major depression disorder (MDD) are severe psychiatric disorders that are challenging to treat, often leading to treatment resistance (TR). It is crucial to develop effective methods to identify and treat patients at risk of TR at an early stage in a personalized manner, considering their biological basis, their clinical and psychosocial characteristics. Effective translation of theoretical knowledge into clinical practice is essential for achieving this goal.

In Situ Monitoring of Mechanofluorescence in Polymeric Nanofibers.

Macromol Rapid Commun

December 2024

Department of Chemistry "Giacomo Ciamician", University of Bologna, Via Selmi 2, Bologna, 40126, Italy.

Mechanofluorescent polymers represent a promising class of materials exhibiting fluorescence changes in response to mechanical stimuli. One approach to fabricating these polymers involves incorporating aggregachromic dyes, whose emission properties are governed by the intermolecular distance, which can, in turn, be readily altered by microstructural changes in the surrounding polymer matrix during mechanical deformation. In this study, a mechanofluorescent additive featuring excimer-forming oligo(p-phenylene vinylene) dyes (tOPV) is incorporated into electrospun polyurethane fibers, producing mats of fibers with diameters ranging from 300 to 700 nm.

The ER-resident proteins VMP1 and TMEM41B share a conserved DedA domain, which confers lipid scramblase activity. Loss of either gene results in embryonic lethality in mice and defects in autophagy and lipid droplet metabolism. To investigate their role in pluripotency and lineage specification, we generated Vmp1 and Tmem41b mutations in mouse embryonic stem cells (ESCs).

The role of evolving niche choice in herbivore adaptation to host plants.

J Evol Biol

December 2024

Department of Theoretical Biology, Faculty of Biology, Bielefeld University, Universit ätsstraÿe 25, 33615 Bielefeld, Germany.

Article Synopsis
  • Individuals in diverse environments often select microenvironments that enhance their fitness, which can lead to quicker adaptation and greater genetic diversity.
  • The study explores how niche choice and evolution influence the development of insecticide resistance in plant-eating insects using an individual-based model.
  • Findings indicate that targeted oviposition (egg-laying) behavior slows down the evolution of resistance compared to random egg placement, promoting the coexistence of different insect types and suggesting that genetic factors also play a significant role.

Ebola virus disease model with a nonlinear incidence rate and density-dependent treatment.

Infect Dis Model

September 2024

Committed Mathematics Team, Research Unit in Mathematics and Applications, Department of Mathematics and Computer Science, University of Dschang, P.O. Box 67 Dschang, Cameroon.

This paper studies an Ebola epidemic model with an exponential nonlinear incidence function that considers the efficacy and the behaviour change. The current model also incorporates a new density-dependent treatment that catches the impact of the disease transmission on the treatment. Firstly, we provide a theoretical study of the nonlinear differential equations model obtained.

Background: Cancer immunotherapy has revolutionized melanoma treatment, but the high number of non-responders still emphasizes the need for improvement of therapy. One potential avenue for enhancing anti-tumor treatment is through the modulation of coagulation and platelet activity. Both have been found to play an important role in the tumor microenvironment, tumor growth and metastasis.

Plant Biol (Stuttg)

January 2025

Institute for Organismic and Molecular Evolution (iomE), Johannes Gutenberg University of Mainz, Mainz, Germany.

Article Synopsis
  • The giant duckweed Spirodela polyrhiza is a fast-growing plant with high flavonoid content, making it promising for food production and metabolic engineering.
  • Researchers analyzed 137 genotypes of S. polyrhiza to understand the genetic factors influencing growth and various metabolites, using a genome-wide association approach.
  • They found that growth is linked to certain amino acids but inversely related to flavonoids, identifying key genes that could improve both growth and metabolite production for potential industrial use.

Background: Uncertainty is a widespread phenomenon experienced worldwide. The bulk of existing research to date has focused on transitory or acute experiences of uncertainty, often in the particular context of illness. The current study evaluated the psychometric properties of the cross-contextual 40-item (long) and 20-item (short) Chronic Uncertainty scale (CU-40; CU-20).

Increased incidence rates for childhood leukaemia have been reported in municipalities close to the nuclear power plant (NPP) Krümmel (Geesthacht, Germany). Methodological challenges arise when analysing this association at ecological level. They include the use of an appropriate reference population, unstable estimates of standardised incidence ratios (SIRs), and the potential role of prevailing winds.
