Article Synopsis
  • - The main focus of diagnostic medicine has shifted towards detecting critical events from extremely small samples, raising questions about how accurately rare cell events represent tumor diseases and their diversity.
  • - This review highlights recent techniques for isolating and characterizing these rare cell events, particularly circulating tumor cells, emphasizing the importance of studying them at the single-cell level.
  • - The discussion also explores the biological significance of these cells and their implications for precision medicine, considering potential applications in treating and understanding tumors better.

Hippocampal subfields in adolescent anorexia nervosa.

Psychiatry Res Neuroimaging

December 2018

Department of Psychology, Faculty of Health Sciences, UiT The Artic University of Norway, Tromsø, Norway; Regional Center for Eating Disorders, University hospital of North Norway, Norway.

Patients with anorexia nervosa (AN) exhibit volume reduction in cerebral gray matter (GM), and several studies report reduced hippocampus volume. The hippocampal subfields (HS) are functionally and structurally distinct, and appear to respond differently to neuropathology. The aim of this study was to investigate HS volumes in adolescent females with restrictive AN compared to a healthy age-matched control group (HC).

The practice of support personnel, supervised by physiotherapists, in Norwegian reablement services.

Physiother Res Int

January 2019

Department of Health and Care Sciences, University of Tromsø, The Artic University of Norway, Tromsø, Norway.

Objectives: Reablement is a relatively new service targeting people with or at risk of functional decline. The approach is team based, and physiotherapists (PTs), occupational therapists, and nurses have the responsibility to guide and supervise the support personnel, referred to as home trainers (HTs). The aim of this study was to explore how the HTs follow up instructions and supervision by PTs in reablement.

Flagella-mediated secretion of a novel cytotoxin affecting both vertebrate and invertebrate hosts.

Commun Biol

June 2018

Department of Molecular Biology and The Laboratory for Molecular Infection Medicine Sweden (MIMS), Umeå University, SE-90187, Umeå, Sweden.

Using as an infection host model for predator interactions, we discovered a bacterial cytotoxin, MakA, whose function as a virulence factor relies on secretion via the flagellum channel in a proton motive force-dependent manner. The MakA protein is expressed from the polycistronic (otility-ssociated lling factor) operon. Bacteria expressing induced dramatic changes in intestinal morphology leading to a defecation defect, starvation and death in .

Reactive stroma is a tissue feature commonly observed in the tumor microenvironment of prostate cancer and has previously been associated with more aggressive tumors. The aim of this study was to detect differentially expressed genes and metabolites according to reactive stroma content measured on the exact same prostate cancer tissue sample. Reactive stroma was evaluated using histopathology from 108 fresh frozen prostate cancer samples gathered from 43 patients after prostatectomy (Biobank1).

Direct Measurement of the Magnitude of the van der Waals Interaction of Single and Multilayer Graphene.

Langmuir

Laboratory for Energy and NanoScience (LENS) , Khalifa University of Science and Technology , Masdar Institute Campus, Abu Dhabi 54224 , UAE.

Vertical stacking of monolayers via van der Waals (vdW) assembly is an emerging field that opens promising routes toward engineering physical properties of two-dimensional materials. Industrial exploitation of these engineering heterostructures as robust functional materials still requires bounding their measured properties so as to enhance theoretical tractability and assist in experimental designs. Specifically, the short-range attractive vdW forces are responsible for the adhesion of chemically inert components and are recognized to play a dominant role in the functionality of these structures.

Various subtypes of breast cancer defined by estrogen receptor (ER), progesterone receptor (PR), and HER2 exhibit etiologic differences in reproductive factors, but associations with other risk factors are inconsistent. To clarify etiologic heterogeneity, we pooled data from nine cohort studies. Multivariable, joint Cox proportional hazards regression models were used to estimate HRs and 95% confidence intervals (CI) for molecular subtypes.

Background And Purpose: Group-based interventions for people with multiple sclerosis (MS) have gained increased attention in the field of physiotherapy research. However, no studies have investigated whether or how the prevailing principle of individualization is embedded in such interventions. The purpose of this study was to investigate how professional actions and interactions affect individualized exercise adaptations in a group intervention for people with MS.

Background: Brief measures of health-related quality of life (HRQOL) that assess both patient-reported functioning and well-being after stroke are scarce. The objective of this study was to examine reliability and validity of one of these measures, the patient-reported Quality of Life after Brain Injury-Overall Scale (QOLIBRI-OS), in patients after stroke.

Methods: Stroke survivors were examined prospectively using survey methods.

The main aim of the paper is damage detection at the microscale in the anisotropic piezoelectric sensors using surface acoustic waves (SAWs). A novel technique based on the single input and multiple output of Rayleigh waves is proposed to detect the microscale cracks/flaws in the sensor. A convex-shaped interdigital transducer is fabricated for excitation of divergent SAWs in the sensor.

The Western culturally developed Hopkins Symptom Checklist (HSCL-10) is a self-report measure of mental distress widely used for both clinical and epidemiological purposes - also in the multiethnic epidemiological SAMINOR studies in Northern Norway, but without any proper cross-cultural validation. Our objective was to test invariance of the HSCL-10 measurements among Sami and the non-indigenous majority population in Northern Norway (participants in the SAMINOR 2 study) and whether the previously used HSCL-10 cut-off level (1.85) fits the Sami subgroups in the study.

Background: Obesity is an established risk factor for several common chronic diseases such as breast and colorectal cancer, metabolic and cardiovascular diseases; however, the biological basis for these relationships is not fully understood. To explore the association of obesity with these conditions, we investigated peripheral blood leucocyte (PBL) DNA methylation markers for adiposity and their contribution to risk of incident breast and colorectal cancer and myocardial infarction.

Methods: DNA methylation profiles (Illumina Infinium HumanMethylation450 BeadChip) from 1941 individuals from four population-based European cohorts were analysed in relation to body mass index, waist circumference, waist-hip and waist-height ratio within a meta-analytical framework.

The first power weighted version of Hardy's inequality can be rewritten as [Formula: see text] where the constant [Formula: see text] is sharp. This inequality holds in the reversed direction when [Formula: see text]. In this paper we prove and discuss some discrete analogues of Hardy-type inequalities in fractional -discrete calculus.

Background/aim: Typically, prognostic scores predicting survival in patients with metastatic cancer are based on disease- and patient-related factors, such as extent of metastases, age and performance status. Patient-reported symptoms have been included less often. Our group has assessed all patients with the Edmonton Symptom Assessment System (ESAS, a one-sheet questionnaire addressing 11 major symptoms and wellbeing on a numeric scale of 0-10) before palliative radiotherapy (PRT) since 2012.
