Since life emerged on Earth, organisms have had to handle threats and stressors of different kinds. In freshwater ecosystems, one of these ancient stressors is the solar ultraviolet (UV) radiation. Life has been continuously exposed to it, and various behavioural and morphological adaptations have evolved to cope with the stressor. On the other hand, human activities have introduced novel stressor

Background: Summary statistics often hide individual patients' suffering, thereby impeding quality improvement efforts. Objectives: We aimed to show the experience of a population with health care toward the end of life while preserving the experience of the individual. Design: We developed a data display method called per-patient illness trajectory analysis. We tested it using a demonstration coh

BackgroundCerebral small vessel disease (CSVD) is one of the most important causes of cognitive decline. Only a few previous studies have evaluated lung function measures in relation to brain neuropathological changes, and even less studies on specific lesions and areas that could shed light on mechanisms of CSVD.ObjectiveThe aim was to study the association between lung function and CSVD in the g

Background: Migratory birds play an important part in the spread of parasites, with more or less impact on resident birds. Previous studies focus on the prevalence of parasites, but changes in infection intensity over time have rarely been studied. As infection intensity can be quantified by qPCR, we measured infection intensity during different seasons, which is important for our understanding of

Diving and Hyperbaric Medicine. 2022 December 20;52(4):281−285. doi: 10.28920/dhm52.4.281-285. PMID: 36525686.) Introduction: Intravascular bubble load after decompression can be detected and scored using ultrasound techniques that me

Objective: To evaluate in low-risk pregnancies if longitudinal change in cerebro-placental ratio (CPR) between 37 and 40 weeks of pregnancy is associated with cesarean section (CS) for non-reassuring fetal status (NRFS) during labor. Methods: This is a prospective observational study of women with singleton low-risk pregnancies who underwent an ultrasound scan at 36 + 0 to 37 + 6 and 39 + 0 to 41

A stochastic hierarchical model for the evolution of low grade gliomas is proposed. Starting with the description of cell motion using a piecewise diffusion Markov process (PDifMP) at the cellular level, we derive an equation for the density of the transition probability of this Markov process based on the generalised Fokker–Planck equation. Then, a macroscopic model is derived via parabolic limit
