Cerebral palsy is a complex lifespan disability caused by a lesion to the immature brain. Evaluation of interventions for children with cerebral palsy requires valid and reliable outcome measures. Motor development curves and reference percentiles for The Gross Motor Function Measure (GMFM-66) are valuable tools for following, predicting, comparing, and evaluating changes in gross motor skills.

This work introduces a novel methodology for identifying critical sensor locations and detecting defects in structural components. Initially, a hybrid method is proposed to determine optimal sensor placements by integrating results from both the discrete empirical interpolation method (DEIM) and the random permutation features importance technique (PI). Subsequently, the identified sensors are utilized in a novel defect detection approach, leveraging a semi-intrusive reduced order modeling and genetic search algorithm for fast and reliable defect detection.

The effectiveness of bariatric surgery in reducing remnant cholesterol (RC) levels, particularly when obesity is accompanied by elevated glycated hemoglobin (HbA1c), is insufficiently investigated. In this study, we aimed to examine the impacts of two common bariatric procedures, Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG), as regards their effects on RC and HbA1c levels. Adult morbidly obese subjects were included and assigned to receive either RYGB or SG.

Background: Nursing students' clinical learning is premised on experiences in clinical placements in nurse education, with the processes and outcomes of tripartite meetings among the student, nurse preceptor and teacher being central components. The tripartite meetings form the basis and framework for stakeholders' dialogue and collaboration and have the central purpose of facilitating student learning and development and assessing the students' achievement against predetermined learning outcomes for the placement period. Students' experiences with tripartite meetings seems to be an underexplored field, and therefor this study aimed to explore first-year nursing students' learning experiences within tripartite clinical placement meetings in nursing homes.

The genetic architecture of differentiating behavioral and emotional problems in early life.

Biol Psychiatry

January 2025

PsychGen Center for Genetic Epidemiology and Mental Health, Norwegian Institute of Public Health, Oslo, Norway; Psychiatric Genetic Epidemiology group, Research Department, Lovisenberg Diaconal Hospital, Oslo, Norway; MRC Integrative Epidemiology Unit, Bristol Medical School, University of Bristol, Bristol, UK. Electronic address:

Background: Early in life, behavioral and cognitive traits associated with risk for developing a psychiatric condition are broad and undifferentiated. As children develop, these traits differentiate into characteristic clusters of symptoms and behaviors that ultimately form the basis of diagnostic categories. Understanding this differentiation process - in the context of genetic risk for psychiatric conditions, which is highly generalized - can improve early detection and intervention.

Pollutants emitted from all over the world may reach pristine areas, such as the Arctic. The Svalbard reindeer (Rangifer tarandus platyrhynchus) has been the subject of a few studies reporting toxic metal concentrations. However, these studies either date back a few decades or exclusively used non-invasive samples (e.

Associations between variants in the FTO locus and plasma concentrations of appetite related hormones are inconsistent, and might not work in a dose dependent fashion in people with obesity. Moreover, it is relevant to report meal related plasma concentrations of these hormones in persons with obesity given the growing interest in their pharmacological potential in obesity therapy. We find it clinically relevant to examine associations between the SNP rs9939609 genotypes and homeostatic appetite regulation in individuals with BMI ≥35 kg/m2.

Introduction: Somalia is continuing to recover from three decades of underdevelopment, political instability, civil unrest, and protracted humanitarian crises. However, Somalia has one of the lowest maternal health indicators in the world. For instance, the maternal mortality ratio is 621 per 100,000 live births.

Stepwise Structural Relaxation in Battery Active Materials.

ACS Mater Lett

January 2025

Centre for Materials Science and Nanotechnology, Department of Chemistry, University of Oslo, PO Box 1033, Blindern 0315 Norway.

Whenever the cycling of Li-ion batteries is stopped, the electrode materials undergo a relaxation process, but the structural changes that occur during relaxation are not well-understood. We have used operando synchrotron X-ray diffraction with a time resolution of 1.24 s to observe the structural changes that occur when the lithiation of graphite and LiFePO electrodes are interrupted.

Aim: To understand the extent and type of evidence in relation to the effectiveness of intervention strategies targeting working pregnant women, and their partners, for the prevention of mental health problems (depression, anxiety) and improving resilience, from conception until the child is 5 years of age.

Methods: A scoping review was conducted searching Pubmed (including Medline), Embase, Web of Science Core Collection and Scopus. Inclusion criteria were based on population (employed parents), context (from -9 months to 5 years postpartum) and concept (mental health problems, resilience and prevention/ preventative interventions).

Trophic interactions regulate populations, but anthropogenic processes influence primary productivity and consumption by both herbivore and carnivore species. Trophic ecology studies often focus on natural systems such as protected areas, even though livestock globally comprise the majority of terrestrial vertebrate biomass. Here we explore spatial and temporal patterns in the distribution of biomass between plants, and large herbivores and carnivores (> 10 kg) in Norwegian rangelands, including both wildlife and livestock.

No winter halt in below-ground wood growth of four angiosperm deciduous tree species.

Nat Ecol Evol

January 2025

PLECO Plants and Ecosystems Research Group, Department of Biology, University of Antwerp, Wilrijk, Belgium.

In the temperate zone, deciduous trees exhibit clear above-ground seasonality, marked by a halt in wood growth that represents the completion of wood formation in autumn and reactivation in spring. However, the growth seasonality of below-ground woody organs, such as coarse roots, has been largely overlooked. Here we use tree monitoring data and pot experiments involving saplings to examine the late-season xylem development of stem and coarse roots with leaf phenology in four common deciduous tree species in Western Europe.

Background: Despite strong evidence-based strategies for prevention and management, global efforts to reduce deaths from postpartum haemorrhage (PPH) have failed, and it remains the leading cause of maternal mortality. We conducted a detailed review of all maternal deaths from 33 facilities in Malawi to identify health system weaknesses leading to deaths from PPH.

Methods: Data were collected regarding every maternal death occurring across all district and central hospitals in Malawi.

Center for Environmental Radioactivity (CERAD) CoE, Norwegian University of Life Sciences, P.O. Box 5003, N-1432 Ås, Norway; Faculty of Environmental Sciences and Natural Resource Management, Norwegian University of Life Sciences (NMBU), P.O.Box 5003, NO-1432 Ås, Norway.

Numerical transport models are important tools for nuclear emergency decision makers in that they rapidly provide early predictions of dispersion of released radionuclides, which is key information to determine adequate emergency protective measures. They can also help us understand and describe environmental processes and can give a comprehensive assessment of transport and transfer of radionuclides in the environment. Transport of radionuclides in air and ocean is affected by a number of different physico-chemical processes.

Quantitative imaging of loop extruders rebuilding interphase genome architecture after mitosis.

J Cell Biol

March 2025

Cell Biology and Biophysics Unit, European Molecular Biology Laboratory (EMBL) , Heidelberg, Germany.

How cells establish the interphase genome organization after mitosis is incompletely understood. Using quantitative and super-resolution microscopy, we show that the transition from a Condensin to a Cohesin-based genome organization occurs dynamically over 2 h. While a significant fraction of Condensins remains chromatin-bound until early G1, Cohesin-STAG1 and its boundary factor CTCF are rapidly imported into daughter nuclei in telophase, immediately bind chromosomes as individual complexes, and are sufficient to build the first interphase TAD structures.
