Early life exposure to halogenated persistent organic pollutants, such as polychlorinated biphenyls (PCBs), the DDT metabolite p,p'-dichlorodiphenyldichloroethane (p,p'-DDE), polybrominated diphenylethers (PBDEs), and hexabromocyclododecane (HBCD), may affect human health. We determined if there are regional differences in mother's milk levels of these compounds in Sweden. In year 2000-2004, milk
Evidences exist that dopamine is involved in T-cell homeostasis. Here, we investigated if daily treatment with levodopa (20mg/kg)/benserazide (15mg/kg) regulates the number of T-cells in the blood of Sprague Dawley rats subjected to transient occlusion of the middle cerebral artery (tMCAO). T-cells and associated inflammatory cytokines were analyzed in the blood one week after tMCAO. Treatment wit
MicroRNAs (miRNAs) are important regulators of gene function and manipulation of miRNAs is a central component of basic research. Modulation of gene expression by miRNA gain-of-function can be based on different approaches including transfection with miRNA mimics; artificial, chemically modified miRNA-like small RNAs. These molecules are intended to mimic the function of a miRNA guide strand while
Antibody-based microarrays are a rapidly evolving affinity-proteomic methodology that recently has shown great promise in clinical applications. The resolution of these proteomic analyses is, however, directly related to the number of data-points, i.e. antibodies, included on the array. Currently, this is a key bottleneck due to limited availability of numerous highly-characterized antibodies. Her
Abstract Objective. Few large-scale studies have examined the prevalence of irritable bowel syndrome (IBS) and the number of visits among IBS patients in a primary health care setting. The aim of this study was to assess the prevalence of IBS in primary health care in four Swedish counties. Another aim was to study the number of visits among the IBS patients. Design. A register-based study. Settin
Peroxidase-like activity of Vitreoscilla hemoglobin (VHb) has been recently disclosed. To maximize such activity, two catalytically conserved residues (histidine and arginine) found in the distal pocket of peroxidases have successfully been introduced into that of the VHb. A 15-fold increase in catalytic constant (k(cat)) was obtained in P54R variant, which was presumably attributable to the lower
-Early diagnosis and risk stratification is of clinical importance in the Long QT Syndrome (LQTS), however little genotype-specific data are available regarding fetal LQTS. We investigate third trimester fetal heart rate, routinely recorded within public maternal health care, as a possible marker for LQT1 genotype and phenotype.
The complement system is key to innate immunity and its activation is necessary for the clearance of bacteria and apoptotic cells. However, insufficient or excessive complement activation will lead to immune-related diseases. It is so far unknown how the complement activity is up- or down-regulated and what the associated pathophysiological mechanisms are. To quantitatively understand the modulato
Temporomandibular disorders (TMD) include craniocervical pain conditions with unclear etiologies. Central changes are suspected; however, few neuroimaging studies of TMD exist. Single-voxel proton magnetic resonance spectroscopy (H-1-MRS) was used before and after pressure-pain testing to assess glutamate (Glu), glutamine (Gln), N-acetylaspartate (NAA), and choline (Cho) levels in the right and le
In Meru, Tanzania local initiatives were instrumental in establishing a gravity irrigation system in the 1890s. The original property rights institutions governing furrows were characterised by de facto communal ownership and management combined with private temporary user rights. Over the last 12 decades farming systems in Meru have experienced changing land/labour ratios, overall technological a
α-Synuclein (α-syn), a small protein that has the intrinsic propensity to aggregate, is implicated in several neurodegenerative diseases including Parkinson's disease (PD), dementia with Lewy bodies (DLB), and multiple system atrophy (MSA), which are collectively known as synucleinopathies. Genetic, pathological, biochemical, and animal modeling studies provided compelling evidence that α-syn aggr
Time to Return of Spontaneous Circulation (ROSC) has a plausible relation to severity of hypoxic injury before and during resuscitation in Out-of-Hospital Cardiac Arrest (OHCA), and has consistently been associated with adverse outcome. The effect of Targeted Temperature Management (TTM) may not be similar over the full spectrum of time to ROSC. This study investigated the possible beneficial effe
The actions of systemic angiotensin II (AngII) infusions on glomerular permeability were investigated in vivo. In anaesthetized Wistar rats (250-280g) the left ureter was cannulated for urine collection, while simultaneously blood access was achieved. Rats were continuously infused i.v. with either of four doses of AngII (16 ng/kg/min (Lo-AngII; n=7), 230 ng/kg/min (Lo-Int-AngII; n=8), 910 ng/kg/m
Calcium alginate beads, which are biodegradable and biocompatible, have been widely employed as delivery matrices for biomacromolecules. In the present work, the feasibility of encapsulation of DNA (which is used as a model biomacromolecule) in calcium alginate nanobeads (sub-200 nm size), prepared using a recently developed protocol based on the phase inversion temperature (PIT) emulsification me
Five glucosidases were studied with respect to their ability to catalyse the transglycosylation of maltose or cellobiose. Experiments were carried out at high substrate concentrations to increase the ratio between transglycosylation and hydrolysis. The properties of the enzymes were quite different, and as a simple descriptor of transglycosylation ability we suggest the use of the acceptor concent
In this paper, we study the single and double soft behaviors of tree level off-shell currents and on-shell amplitudes in nonlinear sigma model (NLSM). We first propose and prove the leading soft behavior of the tree level currents with a single soft particle. In the on-shell limit, this single soft emission becomes the Adler's zero. Then we establish the leading and subleading soft behaviors of tr
Quantitative information about outdoor thermal comfort, on various temporal and spatial scales, is required to design better cities and mitigate heat problems not only in warm but also in temperate climates. The overall objective of this study is to explore the augmentation of global/regional climate changes by urban features such as geometry in a compact mid-rise high-latitude city (Gothenburg).
