Comparison of cable bacteria genera reveals details of their conduction machinery.

Cable bacteria are centimeter-long multicellular bacteria conducting electricity through periplasmic conductive fibers (PCFs). Using single-strain enrichments of the genera Electrothrix and Electronema we systematically investigate variations and similarities in morphology and electrical properties across both genera. Electrical conductivity of different PCFs spans three orders of magnitude warranting further investigations of the plasticity of their conduction machinery.

Patterns of psychiatric healthcare use during pandemic times among boys and girls with pre-existing diagnoses: a Norwegian nationwide primary and specialist healthcare registry study.

Background: The COVID-19 pandemic introduced complexities that were likely more demanding for some groups, such as children and adolescents, and especially those with pre-existing mental health diagnoses. This study examines long-term patterns of psychiatric healthcare use among this vulnerable group, providing insights into shifts in psychiatric healthcare use during a global health crisis.

Methods: We use data from the primary and specialist healthcare registries available from the Norwegian emergency preparedness register for COVID-19 (Beredt C19) to estimate patterns of psychiatric healthcare use.

Nutritional Support and Physical Activity Intervention Programs with a Person-Centred Approach in People with Chronic Obstructive Pulmonary Disease: a Scoping Review.

Background: The knowledge is sparse in the literature on intervention programs using nutritional support and physical activity for patients with chronic obstructive pulmonary disease within a person-centred approach. We aimed to explore and map the existing evidence on intervention programs with a person-centred approach, focusing on nutritional support and physical activity for people with COPD.

Methods: A scoping review was conducted using Arksey & O'Malley's methodological framework.

Angiotensin-(1-5) is a Potent Endogenous Angiotensin AT -Receptor Agonist.

Background: The renin-angiotensin system involves many more enzymes, receptors and biologically active peptides than originally thought. With this study, we investigated whether angiotensin-(1-5) [Ang-(1-5)], a 5-amino acid fragment of angiotensin II, has biological activity, and through which receptor it elicits effects.

Methods: The effect of Ang-(1-5) (1µM) on nitric oxide release was measured by DAF-FM staining in human aortic endothelial cells (HAEC), or Chinese Hamster Ovary (CHO) cells stably transfected with the angiotensin AT -receptor (AT R) or the receptor Mas.

Evaluation of Validity and Reliability of a German General and Sports Nutrition Knowledge Questionnaire for Athletes and Coaches (GSNKQ-AC).

Despite the availability of nutritional recommendations, studies have reported inadequate nutrition in athletes. The existing literature highlights the importance of the nutritional knowledge of both athletes and coaches in influencing athletes' food choices and behavior, as well as its direct and indirect impact on athletes' performance and health. To adequately assess nutritional knowledge, monitoring via valid and reliable questionnaires is required.

Disturbed bone marrow adiposity in patients with Cushing's syndrome and glucocorticoid- and postmenopausal- induced osteoporosis.

Background: Skeletal stem/progenitor cells (SSPCs) in the bone marrow can differentiate into osteoblasts or adipocytes in response to microenvironmental signalling input, including hormonal signalling. Glucocorticoids (GC) are corticosteroid hormones that promote adipogenic differentiation and are endogenously increased in patients with Cushing´s syndrome (CS). Here, we investigate bone marrow adiposity changes in response to endogenous or exogenous GC increases.

Orthopaedic patients' experiences of their sleep during hospitalisation and suggestions for improvements.

Purpose: To describe orthopaedic patients' perspectives on their sleep quality and their suggestions for improvement initiatives to achieve better sleep quality during hospitalisation.

Methods: In a qualitative design, 265 (50%) of 533 patients from a questionnaire survey responded to two free-text questions. Data were analysed based on a phenomenological-hermeneutic approach inspired by Paul Ricoeur's theory of narrative and interpretation.

Contact with primary care physicians among adults with pre-existing common mental health problems during the COVID-19 pandemic: a registry-based study from Norway.

Background: During the COVID-19 pandemic, individuals with pre-existing mental health problems may have experienced additional stress, which could worsen symptoms or trigger relapse. Thus, this study aimed to investigate if the number of consultations with general practitioners (GPs) among individuals with a pre-existing common mental health problem during the pandemic differed from pre-pandemic years.

Methods: Data on consultations with GPs among 18-65-year-olds registered with common mental health problems in 2017-2021 were retrieved from the Norwegian Control and Payment of Health Reimbursements Database.

Incidence rates of treated mental disorders before and during the COVID-19 pandemic-a nationwide study comparing trends in the period 2015 to 2021.

Background: There is a concern that exposure to psychosocial stressors during the COVID-19 pandemic may have led to a higher incidence of mental disorders. Thus, this study aimed to compare trends in incidence rates of depressive disorder, anxiety disorders, obsessive-compulsive disorder (OCD), post-traumatic stress disorder (PTSD), and eating disorders in primary- and specialist health care before (2015-2019) and during the COVID-19 pandemic (2020-2021).

Methods: We used aggregated population registry data to calculate incidence rates of mental disorders from primary- (The Norwegian Control and Payment of Health Reimbursements Registry (KUHR)) and specialist (The Norwegian Patient Registry (NPR)) health care.

Implementation of ultrasound-guided carpal tunnel release.

Introduction: Ultra-minimally invasive ultrasound-guided carpal tunnel release is a surgical procedure for treatment of carpal tunnel syndrome that is associated with less surgery-related morbidity and faster recovery than open surgery. The objectives of this study were to describe how the surgical technique may be acquired and to report the results obtained after implementation in a clinical setting.

Methods: The study consisted of two parts: 1) description of the surgical skills needed to perform the procedure, and 2) evaluation of the procedure in the first ten consecutively operated patients after 12-month follow-up using questionnaires and magnetic resonance imaging (MRI).

T-cell derived extracellular vesicles prime macrophages for improved STING based cancer immunotherapy.

A key phenomenon in cancer is the establishment of a highly immunosuppressive tumour microenvironment (TME). Despite advances in immunotherapy, where the purpose is to induce tumour recognition and hence hereof tumour eradication, the majority of patients applicable for such treatment still fail to respond. It has been suggested that high immunological activity in the tumour is essential for achieving effective response to immunotherapy, which therefore have led to exploration of strategies that triggers inflammatory pathways.

'Why doesn't anyone ask me'? Patients' experiences of receiving, performing and practices of oral care in an acute Orthopaedic Department.

Aims And Objectives: Oral care is an integrated part of everyday life. Within nursing, barriers related to providing oral care often lead to unmet caring needs. Poor oral care is associated with a risk of respiratory and cardiovascular complications during hospitalisation.

A Critical Role of the Bone Marrow Envelope in Human Bone Remodeling.

Proper bone remodeling depends not only on a team of bone-resorbing osteoclasts and bone-forming osteoblasts. It also depends on the site-specific delivery of a large amount of osteoblast lineage cells to the bone remodeling site. How this delivery occurs is poorly known.

Golgi fragmentation - One of the earliest organelle phenotypes in Alzheimer's disease neurons.

Alzheimer's disease (AD) is the most common cause of dementia, with no current cure. Consequently, alternative approaches focusing on early pathological events in specific neuronal populations, besides targeting the well-studied amyloid beta (Aβ) accumulations and Tau tangles, are needed. In this study, we have investigated disease phenotypes specific to glutamatergic forebrain neurons and mapped the timeline of their occurrence, by implementing familial and sporadic human induced pluripotent stem cell models as well as the 5xFAD mouse model.

Post-translational proteomics platform identifies neurite outgrowth impairments in Parkinson's disease GBA-N370S dopamine neurons.

Variants at the GBA locus, encoding glucocerebrosidase, are the strongest common genetic risk factor for Parkinson's disease (PD). To understand GBA-related disease mechanisms, we use a multi-part-enrichment proteomics and post-translational modification (PTM) workflow, identifying large numbers of dysregulated proteins and PTMs in heterozygous GBA-N370S PD patient induced pluripotent stem cell (iPSC) dopamine neurons. Alterations in glycosylation status show disturbances in the autophagy-lysosomal pathway, which concur with upstream perturbations in mammalian target of rapamycin (mTOR) activation in GBA-PD neurons.

Ceruloplasmin-deficient mice show changes in PTM profiles of proteins involved in messenger RNA processing and neuronal projections and synaptic processes.

Ceruloplasmin (Cp) is a multicopper oxidase with ferroxidase properties being of importance to the mobilisation and export of iron from cells and its ability to bind copper. In ageing humans, Cp deficiency is known to result in aceruloplasminemia, which among other is characterised by neurological symptoms. To obtain novel information about the functions of Cp in the central nervous system (CNS) we compared the brain proteome in forebrains from asymptomatic 4-6-month-old Cp-deficient (B6N(Cg)-Cp /J) and wild-type mice.

Estimated glomerular filtration rate based on creatinine, cystatin C, β-trace protein and β2 microglobulin in patients undergoing nontraumatic lower extremity amputation.

Aims: The study's aim is to compare current and new equations for estimating glomerular filtration rate (GFR) based on creatinine, cystatin C, β-trace protein (BTP) and β2 microglobulin (B2M) among patients undergoing major amputation.

Methods: This is a secondary analysis of data from a prospective cohort study investigating patients undergoing nontraumatic lower extremity amputation. Estimated GFR (eGFR) was calculated using equations based on creatinine (eGFRcre[2009] and eGFRcre[2021]), cystatin C (eGFRcys), the combination of creatinine and cystatin C (eGFRcomb[2012] and eGFRcomb[2021]) or a panel of all 4 filtration markers (eGFRpanel).

Quantitative Phosphoproteomics and Acetylomics of Safranal Anticancer Effects in Triple-Negative Breast Cancer Cells.

Safranal, as an aroma in saffron, is one of the cytotoxic compounds in saffron that causes cell death in triple-negative breast cancer cells. Our recent research reported the anti-cancer effects of safranal, which further demonstrated its impact on protein translation, mitochondrial dysfunction, and DNA fragmentation. To better understand the underlying mechanisms, we identified acetylated and phosphorylated peptides in safranal-treated cancer cells.

Artificial intelligence assisted compositional analyses of human abdominal aortic aneurysms .

Quantification of histological information from excised human abdominal aortic aneurysm (AAA) specimens may provide essential information on the degree of infiltration of inflammatory cells in different regions of the AAA. Such information will support mechanistic insight in AAA pathology and can be linked to clinical measures for further development of AAA treatment regimens. We hypothesize that artificial intelligence can support high throughput analyses of histological sections of excised human AAA.

Coping, Social Support and Loneliness during the COVID-19 Pandemic and Their Effect on Depression and Anxiety: Patients' Experiences in Community Mental Health Centers in Norway.

Little is known about psychiatric patients' experiences during the COVID-19 pandemic. The purpose of this study was to investigate associations of coping strategies, social support and loneliness with mental health symptoms among these patients. : We recruited 164 patients from Community Mental Health Centers in June-July 2020.

Comprehensive proteomics and sialiomics of the anti-proliferative activity of safranal on triple negative MDA-MB-231 breast cancer cell lines.

Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer with no efficient treatment. Researchers have indicated the importance of quantitative approaches on proteome and different post-translation modifications studies both in diagnosis and treatment purposes. Sialic acid-containing glycopeptides (the sialiome) is one of these modifications which can be used as a tool in cancer diagnosis or therapeutic strategies since the sialylation is strongly associated with cancer migration and metastasis.
