Identification and characterization of leukemia-initiating cells (LICs) is important to understand leukemogenesis and develop novel therapies for leukemia. In this issue of Cell Stem Cell, Gibbs et al. (2012) demonstrate that common active signaling pathways in LICs may be targeted to treat acute myeloid leukemia.
BACKGROUND:: Platelets not only control thrombosis and haemostasis but may also regulate inflammatory processes. Acute pancreatitis (AP) is characterized by changes in both coagulation and proinflammatory activities. The role of platelets in AP is not yet known. METHODS:: AP was induced in C57BL/6 mice by repeated caerulein administration (50 µg/kg intraperitoneally). Mice received a platelet-depl
Identifying the genes and pathways that regulate self-renewal and differentiation in somatic stem cells is a central goal in stem cell and cancer biology. Here, we describe a method for RNAi-based screens in primary human hematopoietic stem and progenitor cells. These cells are suitable targets for complex, selection-based screens using pooled lentiviral shRNA libraries. The screening approach is
The aim of this report is to illustrate how the affected after disasters have experienced their situation and the support from authorities. The study is based on interviews with 16 persons after the storm Gudrun in southern Sweden 2005, the Asian tsunami 2004 and an accident with toxic gas in a Swedish town 2005. The affected received most support, both practical and emotional, from their social
OBJECTIVES: To estimate risks of fatal/nonfatal coronary heart disease (CHD), stroke and cardiovascular disease (CVD) with SBP in an observational study of patients with type 2 diabetes. METHODS: Twelve thousand, six hundred and seventy-seven patients aged 30-75 years, treated with antihypertensive drugs, without previous congestive heart failure, followed for 5 years. RESULTS: Risk curves of CHD
Introduction: Dementia remains incurable, and treatment trials are typically conducted after the symptoms manifest, potentially too late in the disease process to alter its course. Early identification and intervention during the pre-diagnosis phase offer the potential to introduce more cost-effective strategies and enhance quality of life. This review aims to scrutinise emerging evidence and pres
BACKGROUND: The impact of the sustainable EAT-Lancet planetary health diet on brain and cognitive health remains unclear. This study compared the impact of the EAT-Lancet diet with the well-established cognitive-beneficial Mediterranean diet (MeDi) in relation to neuroimaging biomarkers and cognitive performance among older adults.METHODS: The study included 615 dementia-free 70-year-olds from the
We present the building blocks of an energy-efficient on-chip platform for neural network applications based on III-V semiconductor nanowires and nanopillar arrays. These will work as emitting and detecting neurosynaptic nodes for spiking nanocircuits, as light sensors that emulate navigational properties of insect vision systems.
The self-assembly of magnetic nanoparticles under external magnetic fields holds great potential for the facile fabrication of functional magnetic components with a wide range of applications. This work employs a technique based on electrically charged gas-phase magnetic nanoparticles, demonstrating an additional level of control when forming one-dimensional assemblies, so-called nanochains, as an
BACKGROUND: Previous post hoc analyses of clinical trials have suggested that a higher percentage of systolic blood pressure time in target range (SBP-TTR) was associated with a decreased risk of cardiovascular disease (CVD). However, there is limited evidence from large prospective cohort studies on the relationship between long-term SBP-TTR and the risk of CVD.OBJECTIVES: The purpose of this stu
Infectious, inflammatory and autoimmune conditions present differently in males and females. SARS-CoV-2 infection in naive males is associated with increased risk of death, whereas females are at increased risk of long COVID1, similar to observations in other infections2. Females respond more strongly to vaccines, and adverse reactions are more frequent3, like most autoimmune diseases4. Immunologi
Purpose: This study aimed to examine how young people living with Home Mechanical Ventilation experience the transition from childhood to young adulthood in relation to everyday life, perceived health and transition into adult professional healthcare. Methods: Nine young adults (three females and six males aged 18–31) were interviewed, and data was primary analysed using phenomenological hermeneut
Background and objective: Clinical practice guidelines for prostate cancer (PCa) are a valuable resource for everyday clinical practice. The clinical practice guidelines and recommendations produced by various societies should demonstrate a considerable level of consistency in terms of quality, regardless of the society that developed these given the common evidence base. However, to date, no stud
While there is substantial evidence on excess mortality in the first two years of the COVID-19 pandemic, no study has conducted a cause-specific analysis of excess mortality for the whole period 2020–2022 across multiple countries. We examined cause-specific excess mortality during 2020–2022 in Denmark, Finland, Norway, and Sweden—four countries with similar demographics and welfare provisions, wh
Both pain and mental health conditions are common among young people. They often co-occur, but we wanted to investigate further whether it is pain (abdominal pain, headache, musculoskeletal pain, menstrual pain) that precedes mental health conditions (depression, anxiety, stress, phobia) or whether it is the other way around, mental health conditions that precede pain. Using electronic health reco
Genotypes causing pregnancy loss and perinatal mortality are depleted among living individuals and are therefore difficult to find. To explore genetic causes of recessive lethality, we searched for sequence variants with deficit of homozygosity among 1.52 million individuals from six European populations. In this study, we identified 25 genes harboring protein-altering sequence variants with a str
Predation's consequences can manifest through either consumptive or nonconsumptive effects, but the prey response may also vary depending on the predator hunting strategy. Considerable attention has been paid to coursing predators, whereas less information is available regarding responses to ambush predators. To remedy this paucity, we utilized a three-dimensional tracking platform to record group
BACKGROUND: Physical activity (PA) after stroke has significant health benefits if it is conducted regularly, with sufficient intensity and duration. Because of the health benefits, it is important to identify those below the World Health Organization (WHO) recommended level of PA. However, few studies have assessed the level of PA after stroke in relation to the WHO recommendations and which soci
