Background: Patients with somatoform pain experience physical pain that cannot be attributed to any underlying medical or physiological cause, and it is often thought to be related to psychological factors. Health professionals encounter difficulties identifying this specific type of chronic pain, leading to suboptimal treatment strategies. Therefore, we aimed to describe the characteristics of patients with somatoform pain, to support the identification of affected patients.

This work explores the complex hydrodynamics in magnetophoretic microfluidic processes, focusing on the interplay of forces and particle concentrations. The study employs a combined simulation and experimental approach to investigate the impact of magnetophoresis on magneto-responsive nanoparticles (MNPs) and their environment, including non-magneto-responsive nanoparticles (non-MNPs) in a microfluidic system. Our findings reveal that the motion of MNPs induces a hydrodynamic convective motion of non-MNPs, significantly affecting the separation efficiency and purity of the particles.

Aim: The extent to which recent potentially traumatic events (PTEs) hinder the recovery from pre-existing mental health problems is largely unknown. The same applies to the extent to which non-recovery from pre-existing mental health problems increases the risk of posttraumatic stress disorder (PTSD). The aim of the present study is to gain insight in these effects.

Article Synopsis
  • Modern computational chemistry relies on efficient dispersion corrections, like the D3 and D4 models, to improve modeling accuracy for actinides and related compounds.
  • This work successfully expands these models to include the entire series of actinides, plus francium and radium, utilizing a slightly adjusted parameterization strategy and a new data set called AcQM for actinide compounds.
  • The new models show comparable accuracy to more complex methods while maintaining a good balance between computational cost and performance, and they will be available in both standalone codes and the upcoming ORCA 6.0 package.

Background: Clinical case illustrations of patients with an impairment of personality functioning (IPF) have repeatedly reported that progress during psychotherapy is reflected by alterations in dream content. However, quantitative studies based on samples of psychotherapy patients are scarce. As a core component of both personality functioning and contemporary psychodynamic dream theory, the construct of affect regulation is of specific significance in this context.

Article Synopsis
  • Attachment-related anxiety and avoidance are linked to higher risks of developing PTSD after traumatic events, but the extent of pre-event attachment influences PTSD symptoms in the general population is not fully understood.
  • A study with 270 adults assessed attachment styles and mental health symptoms, measuring PTSD severity at multiple points after trauma.
  • The findings indicate that insecure attachment styles, particularly high anxiety, predict worse PTSD symptoms, highlighting the importance of addressing these factors in trauma treatment.

The demand for polymer composite solutions in bipolar plates for polymer electrolyte membrane fuel cells (PEMFCs) has risen due to advantages over metal plates such as longer lifetime, weight reduction, corrosion resistance, flexible manufacturing, freedom of design, and cost-effectiveness. The challenge with polymer composites is achieving both sufficient electrical conductivity and mechanical stability with high filler content. A carbon fiber fleece as reinforcement in a graphite-filled polypropylene (PP) matrix was investigated for use as bipolar plate material with increased mechanical and sufficient conductive properties.

The voice is a variable and dynamic social tool with functional relevance for self-presentation, for example, during a job interview or courtship. Talkers adjust their voices flexibly to their situational or social environment. Here, we investigated how effectively intentional voice modulations can evoke trait impressions in listeners (Experiment 1), whether these trait impressions are recognizable (Experiment 2), and whether they meaningfully influence social interactions (Experiment 3).

Despite the fact that yeast is a widely used microorganism in the food, beverage, and pharmaceutical industries, the impact of viability and age distribution on cultivation performance has yet to be fully understood. For a detailed analysis of fermentation performance and physiological state, we introduced a method of magnetic batch separation to isolate daughter and mother cells from a heterogeneous culture. By binding functionalised iron oxide nanoparticles, it is possible to separate the chitin-enriched bud scars by way of a linker protein.

Background: Findings from prospective studies question the assumption that mental health problems observed in traumatized adults mainly reflect the effects of potentially traumatic events.

Aims: Aim of the present comparative prospective study is to clarify the extent to which victims of potentially traumatic events with mental health, social, financial, and/or legal problems, already suffered from such problems before these events.

Method: Data was extracted from three surveys of the prospective VICTIMS-study (T1 = 2018, T2 = 2019, T3 = 2020), conducted with the population-based longitudinal LISS-panel.

Due to the lack of raw material and forced by political demand, an increasing percentage of postconsumer materials (PCR) shall be used in all processing methods in polymer technology. Thermoforming, as one of the oldest polymer-processing methods, has special requirements regarding the melt stability at high temperatures. Low melt stability affects the thermoforming in a negative manner, as the low stiffness leads the sheet to sag during the heating phase.

An analogue of the metabolite JBIR-141, featuring a delicate -nitrosohydroxylamine, a 3-acyltetramic acid, and an oxazoline, was synthesized by a convergent strategy from l-alanine, l-threonine, and l-glutamic acid. Key steps were the cyclization of an Ala-Thr derivative to give the oxazoline, a Dieckmann condensation affording the 3-acyltetramic acid, and the -nitrosation of a hydroxylamino derivative of glutamic acid. An adequate protecting group strategy was established for coupling the three building blocks.
