A peptide corresponding to a 13-residue segment of the human protein semenogelin I has been shown to generate a hydrogel consisting of amyloid-like fibrils. The relative chemical diversity (compared to synthetic de novo sequences) with 11 distinct amino acids makes this peptide (P0) an ideal candidate for investigating the role of individual residues in gelation. Herein, the N-terminal residues ha
Distinguishing between vagrancy and regular migration has proved to be challenging as vagrants may, in theory, act as pioneers in the establishment of new migration routes. Because migratory songbirds tend to follow the same orientation and migration route throughout their lives, age assessment can help to distinguish individuals which have already used a route (i.e. adults) from those using it fo
A new metaheuristic optimizer combined with artificial neural networks is proposed for streamflow prediction. Hence, the study aimed to forecast monthly streamflow of the main rivers in Urmia, Iran, by considering data shortage and using artificial neural network (ANN) models. By combining three variables: temperature, precipitation, and streamflow, we formulated five patterns, where 70% of the da
Organ donation is a crucial aspect of healthcare, yet, the number of donors is insufficient to cover the demand for transplant procedures. In the European Union, around 15 people die each day waiting for a life-saving organ. National policies differ greatly among countries, but it is unclear how successful policies affect Deceased Organ Donation when introduced in other settings. This paper explor
Background: Previous studies indicate comparably greater improvement in glycaemic control from Paleolithic diet, possibly due to an accompanying greater reduction in body weight, which, in turn, could be due to an accompanying greater reduction in leptin.Aims: To assess in type 2 diabetes the effect of Paleolithic diet on glycaemic control when body weight is kept stable and diets matched for macr
An algorithm specific digital signal processor is a powerful alternative to a general purpose signal processor for demanding specifications such as high throughput, low power, small size, etc. These properties are achieved as the processor architecture is tailored to the algorithm as opposed to the general purpose architecture which must suit a wide range of algorithms. The increased performance i
Fractures of the distal end of the radius are common and occur in many different forms. The long-term results after conservative treatment of fracture of the distal end of the radius in younger adults with special reference to degenerative changes and function are investigated in 76 patients (Paper I). After 30 years, 81% of the patients made no difference between the fractured and the non- fractu
Popular Abstract in Swedish Europaparlamentet vill minska primärenergianvändningen samt minska beroendet av energiimport till unionen (EU Direktiv 2012/27/EU). Ett hjälpmedel för att uppnå detta mål kan vara användandet av individuell mätning och debitering (IMD) av värme och varmvatten i flerbostadshus. IMD innebär att boende i flerbostadshus endast ska betala för deras egen konsumtion, vilket skIndividual metering and charging (IMC) means that tenants in multi-apartment buildings should pay only for their own energy consumption, which gives an economic incentive for energy-conscious behaviour. In April, 2014, Swedish legislation about energy metering in buildings (SFS 2014:267) was passed by the Swedish Parliament as an implementation of the EU Energy Efficiency Directive 2012/27/EU. The
Popular Abstract in Swedish Osteoporos (benskörhet) är en sjukdom som drabbar de äldre och leder till att skelettet urkalkas och därmed förlorar delar av sin styrka. Detta bidrager till olika typer av frakturer (brott av benet) där de vanligaste är handleds-, axel-, kot- och höftfrakturer. Andelen frakturer ökar i befolkningen, vilket både medför ökade kostnader för samhället och invaliditet för dThe aim of this thesis was to evaluate bone mass and bone size in girls and boys from age 12 to 16, with special attention to physical activity. We also wanted to retrospectively evaluate the effect of exercise for the years preceding age 12. The findings were as follows. Sixteen year old adolescents in a rural area had higher areal bone mineral density in the total body and the spine compared wit
Objective: To evaluate long-term oncological outcome and surgical quality of robotic radical hysterectomy for cervical cancer. Methods: Consecutive women with stage IA2 to IIA operated between March 2006 and May 2012 with a robotic radical hysterectomy and pelvic lymphadenectomy were prospectively followed up until five years after surgery or until death. Details regarding clinical results, recurr
Popular AbstractI takt med att svenska företag har ökat sina utlandssatsningar med bland annat direktinvesteringar på utländska marknader har också efterfrågan av internationell rörlighet bland den svenska kvalificerade arbetskraften ökat. En del av detta behov rör tidsbegränsade utlandsposteringar av svensk arbetskraft på så kallade ’expats-kontrakt’. Ofta utgår samhällsdebatten från en uppfattniAs Swedish companies have increased their commitments abroad, the demand for internationally mobile skilled Swedish labour has increased. Some of this demand concerns temporary positions on so called ’expats-contracts’. Often the discussion on this issue originates from a discourse that claims this type of labour force to be unanimously positive towards moving abroad to work. International tempora
We used comparative studies to investigate how and why floral and bee fragrances evolve, including courtship odors collected by male Euglossa mixta to form their tibial bouquet, on Coiba Island and other Panama forests. Fragrances of four orchid genera, two used extensively by E. mixta - Coryanthes and Mormodes - and two never used, Clowesia and Catasetum - were also analyzed. From among 636 chemi
Purpose: Transitional cell carcinoma (TCC) of the prostate/prostatic urethra is a risk factor for urethral recurrence after radical cystoprostatectomy for TCC. Using conventional sectioning techniques, prostate involvement (prostatic urethra, acini, ducts and/ or stroma) has been detected in a range of 10-20% of the patients, whereas transversal whole mount sectioning has revealed 43% prostate inv
Remote sensing provides spatially and temporally continuous measures of forest reflectance, and vegetation indices calculated from satellite data can be useful for monitoring climate change impacts on forest tree phenology. Monitoring of evergreen coniferous forest is more difficult than monitoring of deciduous forest, as the new buds only account for a small proportion of the green biomass, and t
d-Amino acids are increasingly being recognized as important signaling molecules in mammals, including humans. d-Serine and d-aspartate are believed to act as signaling molecules in the central nervous system. Interestingly, several other d-amino acids also occur in human plasma, but very little is currently known regarding their function and origin. Abnormal levels of d-amino acids have been impl
