Characterization of directed differentiation of pluripotent stem cells towards therapeutically relevant cell types, including pancreatic beta-cells and hepatocytes, depends on molecular markers and assays that resolve the signature of individual cells. Pancreas and liver both have a common origin of anterior definitive endoderm (DE). Here, we differentiated human embryonic stem cells towards DE us

Smoking is an important cardiovascular risk factor and smoking cessation should be a primary target in secondary prevention after a myocardial infarction (MI).

Neural stem cells are defined as cells that either gives rise to or derives from the cells of the central nervous system and have the unique properties of stem cells, i.e. self-renewal and multipotentiality. One of the widely used methods of expanding neural stem cells under culture conditions is based on the capacity of these cells to divide continuously when cultured in serum-free medium supplem

PURPOSE:: To investigate concordance between objective and perceived neighborhood walkability, their associations with self-reported walking and objective physical activity, and sociodemographic characteristics of individuals in neighborhoods with objectively assessed high walkability who misperceive it as low. METHODS:: In 1,925 individuals aged 20-66 years, recruited from administrative areas in

Background/Aims: Motor impairment is an important aspect of cognitive decline in older adults. It has been suggested that complex motor control is affected earlier than gross motor control. The aims were to investigate if complex hand motor function was more affected than gross motor function in cognitively impaired older subjects, and to present reference values. Methods: Alternating forearm move

Patients with chronic obstructive pulmonary disease commonly suffer from breathlessness, deconditioning, and reduced health-related quality of life (HRQL) despite best medical management. Opioids may relieve breathlessness at rest and on exertion in COPD. We aimed to estimate the efficacy and safety of opioids on refractory breathlessness, exercise capacity, and HRQL in COPD.

In recent years there has been an increased interest in the function of inhibitory interneurons. In the cerebellum this interest has been paired with successes in obtaining recordings from these neurons in vivo and genetic manipulations to probe their function during behavioral tasks such as motor learning. This review focuses on a synthesis of recent findings on the computational properties that

OBJECTIVES: To investigate sick leave and disability pension in working-age subjects with knee osteoarthritis (OA) compared with the general population. METHODS: Population-based cohort study: individual-level inpatient and outpatient Skåne Health Care Register data were linked with data from the Swedish Social Insurance Agency. In 2009 all working-age (16-64 years) Skåne County residents who i

BACKGROUND: Constitutive promoters that ensure sustained and high level gene expression are basic research tools that have a wide range of applications, including studies of human embryology and drug discovery in human embryonic stem cells (hESCs). Numerous cellular/viral promoters that ensure sustained gene expression in various cell types have been identified but systematic comparison of their a

OBJECTIVE: To evaluate a new technical equipment for continuous recording of human fetal scalp temperature in labor.DESIGN: Experimental animal study.METHODS: Two temperature sensors were placed subcutaneously and intracranially on the forehead of 10 fetal lambs and connected to a temperature monitoring system. The system records temperatures simultaneously on-line and stores data to be analyzed o

Multiple biopsies of normal breast tissue from 10 BRCA1 mutation carriers have been analyzed using array-based comparative genomic hybridization. Normal breast tissue from five age-matched control subjects without a family history of breast cancer was included for reference purposes. We repeatedly found multiple low copy number aberrations at a significantly higher frequency in histopathologically

Most patients with acute myeloid leukemia (AML) are older, the median age is 71 years, and survival decreases rapidly with age. The achievement of complete remission and long-term survival mostly require intensive combination chemotherapy, but standard regimens are often believed to be too toxic for older patients. The Swedish Acute Leukemia Registry is unique and contains data on 98% of all patie

Exhaustion is consistently found to be more prevalent in women than in men. Women suffer from job strain more often, which may constitute a partial explanation for this phenomenon, but experienced shortcomings in combining work and family demands may also contribute to ill health. The aim of this study was to investigate, and analyse by gender, how work-related and family-related factors, as well

AIM: To characterize the colon microbiota in two women histologically diagnosed with collagenous colitis using a culture-independent method. METHODS: Biopsies were taken from the ascending colon and the total DNA was extracted. Universal bacterial primers were used to amplify the bacterial 16S rRNA genes. The amplicons were then cloned into competent Escherichia coli cells. The clones were sequen

Systemic or intracerebral delivery of neural stem and progenitor cells (NSPCs) and activation of endogenous NSPCs hold much promise as potential treatments for diseases in the human CNS. Recent studies have shed new light on the interaction between the NSPCs and cells belonging to the innate and adaptive arms of the immune system. According to these studies, the immune cells can be both beneficial

Standardized measurement of self-rated breathlessness using appropriate tools is essential for research and clinical care. The purpose was to review recent advances in the measurement of breathlessness and the minimal clinically important differences (MCIDs) in intensity of chronic breathlessness.

Objective: To study the incidence, prevalence and clinical characteristics of Behçet's disease (BD) in a defined population in southern Sweden. Methods: The study area consists of three health-care districts with an adult population (≥15 years) of 809 317 on 1 January 2011 (25% of non-Swedish ancestry), situated in Skåne, the southernmost county in Sweden. Patients were identified using clinical
