Old Wood in a New Light: An Online Dendrochronological Database

The Old Wood in a New Light database project focuses on the digitization and accessibility of the results of dendrochronological samples analyzed and archived at four Swedish university-based tree-ring laboratories at Lund University, Stockholm University, University of Gothenburg, and the Swedish University of Agricultural Sciences.

IgG with a deviant conformation in serum and synovial fluid from rheumatoid arthritis patients

Specific rabbit antisera were prepared against an IgG with a special conformation (IgG spec.) previously detected in some sera from patients with rheumatoid arthritis. The antibodies had no affinity to normal human IgG and were not anti-idiotypic to human rheumatoid factor. The affinity of IgG spec, to the antibodies could not be explained by an antiglobulin activity to rabbit IgG. The amount of p

Development of an immunoassay for glypressin, an N-terminal extended vasopressin analogue.

The development and evaluation of a radioimmunoassay for Nα-triglycyl-lysine8-vasopressin is described. The site of hapten conjugation of the immunogen has been controlled and the use of various radiolabelled tracers has been evaluated with special reference to the site of iodination. The most extensively studied antiserum showed specificity for the N-terminal triglycyl-extension as well as for se

Effect of viscosity on the pharmacokinetics and biological response to intranasal desmopressin.

he effect of viscosity on the nasal absorption and biological response to desmopressin was studied in humans. Nasal solutions of desmopressin with and without the addition of 0.25% (w/v) methylcellulose were administered by a precompression nasal spray pump to 10 volunteers. Plasma levels of desmopressin were assayed by radioimmunoassay and the biological response was measured by determination of

Systemic and intraocular uptake of spantide, a tachykinin antagonist, following topical application to the rabbit eye.

Previous observations have indicated that topical application to the rabbit eye of tachykinin antagonists, including spantide, effectively prevents the miosis and the disruption of the blood-aqueous barrier consequent to ocular injury. The present study shows that spantide is taken up into the rabbit eye following topical application. This was established by determination of spantide in the aqueou

Effects of intranigral substance P and neurokinin A on striatal dopamine release--I. Interactions with substance P antagonists.

The functional role of striatonigral neurokinins were studied by analysing the effects of intranigral injections of substance P and neurokinin A on the extracellular level of dopamine and dihydroxyphenylacetic acid in the striatum, as measured by in vivo microdialysis in rats. Two substance P antagonists, substance Pd-Pro2d-Trp7,9 and substance Pd-Arg1d-Trp7,9 Leu11 were tested and analysed for th

Site-specific CRISPR-based mitochondrial DNA manipulation is limited by gRNA import

Achieving CRISPR Cas9-based manipulation of mitochondrial DNA (mtDNA) has been a long-standing goal and would be of great relevance for disease modeling and for clinical applications. In this project, we aimed to deliver Cas9 into the mitochondria of human cells and analyzed Cas9-induced mtDNA cleavage and measured the resulting mtDNA depletion with multiplexed qPCR. In initial experiments, we fou

Pharmacokinetics of terlipressin after single i.v. doses to healthy volunteers.

The pharmacokinetics of triglycyl-lysine-vasopressin (TGLVP) were studied in healthy male volunteers after single i.v. injections of 5, 10 and 20 micrograms/kg b. wt. The half-life of distribution and elimination was 8 and 50 min, respectively. The volume of distribution was 0.7 l/kg b.wt. and the plasma clearance 9 ml/kg b.wt./min. These values are different from those for arginine-vasopressin an

Differences in transport rate of oxytocin and vasopressin analogues across proximal and distal isolated segments of the small intestine of the rat.

The transmural intestinal passage of some oxytocin and vasopressin analogues (oxytocin, OT; [Mpa1, D-Arg8]vasopressin, dDAVP; [Mpa1, Tyr (OMe)2, carba6]oxytocin, carbetocin; [Mpa1, D-Tyr (OEt)2, Thr4, Orn8]vasotocin, antocin II; [Mpa1, D-Tyr (OEt)2, Thr4, desPro7Orn8Gly9NH2]tocinoic acid-NH(CH2)3NH2, desPOG-antocin II-NH(CH2)3NH2) was studied using isolated proximal and distal segments in the rat.

Human peripheral blood lymphocytes transplanted into SCID mice constitute an in vivo culture system exhibiting several parameters found in a normal humoral immune response and are a source of immunocytes for the production of human monoclonal antibodies.

Human PBL from vaccinated healthy blood donors, which was transplanted i.p. into mice with severe combined immunodeficiency (SCID), exhibited an Ag-dependent humoral Ir against tetanus toxoid. This Ir was dose dependent and was completely abrogated by immunizing with large amounts of Ag, suggesting a high dose tolerization of the B cells. A dose-dependent selection of specific, high affinity B clo

Real time analysis of antibody-antigen reaction kinetics.

Surface plasmon resonance, i.e. detection of changes in refractive index on a surface, was used in a biosensor to evaluate the dissociation/association rate and affinity constants of human monoclonal IgG and IgM antibodies and Tab fragments. The results showed that an observed difference in affinity constants between intact and fragmented IgG anti-tetanus antibody was related to approximately 10-f

Backyard buzz : human population density modifies the value of vegetation cover for insect pollinators in a subtropical city

Urbanisation drives overall declines in insect pollinators. Although urban green spaces can provide suitable habitat for pollinators much remains to be learned about how urban landscapes either promote or negatively impact pollinators. We investigated how backyard design, local (100 m) and landscape (500 m) scale vegetation cover and human population density were associated with non-eusocial nativ

Intracellular complement : Evidence, definitions, controversies, and solutions

The term “intracellular complement” has been introduced recently as an umbrella term to distinguish functions of complement proteins that take place intracellularly, rather than in the extracellular environment. However, this rather undefined term leaves some confusion as to the classification of what intracellular complement really is, and as to which intracellular compartment(s) it should refer

Observation of the Multilayer Growth Mode in Ternary InGaAs Nanowires

Au-seeded semiconductor nanowires have classically been considered to only grow in a layer-by-layer growth mode, where individual layers nucleate and grow one at a time with an incubation step in between. Recent in situ investigations have shown that there are circumstances where binary semiconductor nanowires grow in a multilayer fashion, creating a stack of incomplete layers at the interface bet

Risk factors for knee osteoarthritis after traumatic knee injury : A systematic review and meta-analysis of randomised controlled trials and cohort studies for the OPTIKNEE Consensus

Objective: To identify and quantify potential risk factors for osteoarthritis (OA) following traumatic knee injury. Design: Systematic review and meta-analyses that estimated the odds of OA for individual risk factors assessed in more than four studies using random-effects models. Remaining risk factors underwent semiquantitative synthesis. The modified GRADE (Grading of Recommendations Assessment

Clinical, economic, and health-related quality of life burden associated with von Willebrand disease in adults and children : Systematic and targeted literature reviews

Introduction: Debilitating clinical complications in von Willebrand disease (VWD) can affect health-related quality of life (HRQoL), increase healthcare costs and cause long-lasting consequences. However, the magnitude of these burdens needs to be more fully explored. Aim: To estimate the prevalence and burden of clinical complications, the impact on HRQoL and the economic burden associated with V
