Imitation is a cornerstone in human development, serving both a cognitive function (e.g. in the acquisition and transmission of skills and knowledge) and a social-communicative function, whereby the imitation of familiar actions serves to maintain social interaction and promote prosociality. In nonhuman primates, this latter function is poorly understood, or even claimed to be absent, yet the evid
Lokshtanov, Marx, and Saurabh SODA 2011 proved that there is no (k-epsilon)^pw(G)poly(n) time algorithm for deciding if an n-vertex graph G with pathwidth pw admits a proper vertex coloring with k colors unless the Strong Exponential Time Hypothesis (SETH) is false, for any constant epsilon>0. We show here that nevertheless, when k>lfloor Delta/2 rfloor + 1, where Delta is the maximum degree in th
Background: Previous research has revealed a clear relationship between weight gain of persons and their metabolic diseases developing later. These studies have covered only short periods lasting 4–8 years. Our goal was to collect decades’ old and often life-long anthropometric data and correlate the figures with the presence of hypertension and diabetes or both. Methods: A retrospective internat
The objective of this study was to determine the prevalence and some predictors for vaccine and non-vaccine types of HPV infections among bivalent HPV vaccinated and non-vaccinated young women in Uganda. This was a comparative cross sectional study 5.5 years after a bivalent HPV 16/18 vaccination (Cervarix®, GlaxoSmithKline, Belgium) pilot project in western Uganda. Cervical swabs were collected b
Object: To present population-based and age related incidence of surgery and clinical outcome for adult patients operated for hydrocephalus, registered in the Swedish Hydrocephalus Quality Registry (SHQR). Methods: All patients registered in SHQR during 2004–2011 were included. Data on age, gender, type of hydrocephalus and type of surgery were extracted as well as three months outcome for patient
Aims/hypothesis: Pancreatic beta cell dysfunction is a prerequisite for the development of type 2 diabetes. Histone deacetylases (HDACs) may affect pancreatic endocrine function and glucose homeostasis through alterations in gene regulation. Our aim was to investigate the role of HDAC7 in human and rat pancreatic islets and clonal INS-1 beta cells (INS-1 832/13). Methods: To explore the role of HD
Tissue damage is usually regarded as a necessary price to pay for successful elimination of pathogens by the innate immune defense. Yet, it is possible to distinguish protective from destructive effects of innate immune activation and selectively attenuate molecular nodes that create pathology. Here, we identify acute cystitis as an Interleukin-1 beta (IL-1β)-driven, hyper-inflammatory condition o
We hypothesized that key signaling pathways of glioma genesis might enable the molecular classification of gliomas. Gene coexpression modules around epidermal growth factor receptor (EGFR) (EM, 29 genes) or platelet derived growth factor receptor A (PDGFRA) (PM, 40 genes) in gliomas were identified. Based on EM and PM expression signatures, nonnegative matrix factorization reproducibly clustered 1
BACKGROUND: Cardiovascular disease (CVD) influences phenotypic variation in Parkinson's disease (PD), and is usually an indication for statin therapy. It is less clear whether cardiovascular risk factors influence PD phenotype, and if statins are prescribed appropriately.OBJECTIVES: To quantify vascular risk and statin use in recent-onset PD, and examine the relationship between vascular risk, PD
Objective To study the characteristics (except congenital malformations) of offspring born to women with a history of malignancy. Methods Data were obtained by linkage between four different Swedish national health registers. We compared the offspring born between 1994 and 2011 of women with a history of malignancy with all other infants. Survival of the infants was followed up through 2013. Adjus
Objective: To investigate possible associations between socioeconomic status (SES) and penile cancer risk, stage at diagnosis, and mortality. Patients/subjects and methods: A population-based register study including men in Sweden diagnosed with penile cancer between 2000 and 2012 (1676 men) and randomly chosen controls (9872 men). Data were retrieved from the National Penile Cancer Register (NPEC
BACKGROUND: Diffuse traumatic axonal injury (TAI), a common consequence of traumatic brain injury, is associated with high morbidity and mortality. Inflammatory processes may play an important role in the pathophysiology of TAI. In the central fluid percussion injury (cFPI) TAI model in mice, the neuroinflammatory and astroglial response and behavioral changes are unknown.METHODS: Twenty cFPI-inju
Purpose We studied whether entrance-related environmental barriers, perceived and objectively recorded, were associated with moving out-of-home daily in older people with and without limitations in lower extremity performance. Methods Cross-sectional analyses of the “Life-space mobility in old age” cohort including 848 community-dwelling 75–90-year-old of central Finland. Participants reported the
Background and purpose - Little is know about patterns of sick leave in connection with total hip and knee joint replacement (THR and TKR) in patients with osteoarthritis (OA). Patients and methods - Using registers from southern Sweden, we identified hip and knee OA patients aged 40-59 years who had a THR or TKR in the period 2004-2012. Patients who died or started on disability pension were excl
The distribution of putative cholinergic neurons in the brain of a cyprinid teleost was investigated by immunocytochemistry, with well‐characterized polyclonal antibodies to porcine choline acetyltransferase (ChAT), correlated with acetylcholinesterase (AChE) histochemistry. AChE‐positive neurons were more numerous than GhAT‐immunoreactive (ChAT‐IR) neurons. Regions with ChAT‐IR neurons generally
The field of microbial ecology has been developing rapidly, largely owing to the introduction of new molecular methods for identifying individuals, species and populations of microorganisms in nature. In contrast to traditional methods, the new ones do not require the isolation and culture of organisms from the environment. With many of the new methods, genotypes and species of microorganisms can
OBJECTIVE: To apply the ATN scheme to memory clinic patients, to assess whether it discriminates patient populations with specific features. METHODS: We included 305 memory clinic patients (33% subjective cognitive decline [SCD]: 60 ± 9 years, 61% M; 19% mild cognitive impairment [MCI]: 68 ± 9 years, 68% M; 48% dementia: 66 ± 10 years, 58% M) classified for positivity (±) of amyloid (A) ([18F]Flor
Negative impact of human activity-related emission of greenhouse gases on Earth's ecosphere has been known for decades, but has recently come into spotlight with unprecedented intensity. This is due to increasingly clear understanding that the global warming could soon spiral out of control. It is therefore essential to diminish the use of fossil fuels and switch to renewable energy sources. Despi
The Genographic Project is an international effort aimed at charting human migratory history. The project is nonprofit and nonmedical, and, through its Legacy Fund, supports locally led efforts to preserve indigenous and traditional cultures. Although the first phase of the project was focused on uniparentally inherited markers on the Y-chromosome and mitochondrial DNA (mtDNA), the current phase f
