Insertion of metals into various tetrapyrroles is catalysed by a group of enzymes called chelatases, e.g. nickel, cobalt, magnesium and ferrochelatase. It has been proposed that catalytic metallation includes distorting the porphyrin substrate by the enzyme towards a transition state-like geometry in which at least one of the pyrrole rings will be available for metal chelation. Here, we present a
Objective: Five double-blind, randomized, saline-controlled trials (RCTs) were included in the United States marketing application for an intra-articular hyaluronan (IA-HA) product for the treatment of osteoarthritis (OA) of the knee. We report an integrated analysis of the primary Case Report Form (CRF) data from these trials. Method. Trials were similar in design, patient population and outcome
Sugarcane bagasse is a potential lignocellulosic feedstock for ethanol production, since it is cheap, readily available, and has a high carbohydrate content. In this work, bagasse was subjected to steam explosion pretreatment with different impregnation conditions. Three parallel pretreatments were carried out, one without any impregnation, a second with sulfur dioxide, and a third with sulfuric a
Recent industrial interest in producing smaller volumes of products in shorter time frames, in contrast to mass production in previous decades, motivated the introduction of human—robot collaboration (HRC) in industrial settings, to increase flexibility in manufacturing applications. As a consequence, industrial environments would lose their fixed structure, thus increasing the uncertainties prese
Background/Aim: The Kingdom of Cristal, an area in southern Sweden, is historically heavily burdened by heavy metals. Cadmium, lead, mercury and arsenic have previously been used in glass production and large amounts of glass crust have been deposited around the Kingdom of Cristal and used as filling material for the construction of new residential areas, parks and schools. The purpose of the proj

Freezing injuries usually take place in thawed plant-based food products. To reduce freezing injuries, Pulse Electric Field (PEF) treatment and Vacuum Impregnation (VI) of cryoprotectant were used before the freezing process. The aim of PEF is to provoke electroporation to the membranes of the plant cells, thereby allowing the cryoprotective solution impregnated by VI to penetrate the cells. PEF
Bakgrund: Obesitas och psykisk ohälsa tillhör de största globala hälsoutmaningarna i modern tid och har under de senaste decennierna varit ett växande problem. Människor har fått en mer stillasittande livsstil och större tillgång på kaloririk föda. Faktorerna som påverkar prevalensen är många men att det behöver ske en förändring är säkert. Syfte och frågeställningar: Syftet var att kartlägga BMI,
This study aimed to understand the exploitation of bacterial strains used in various combinations to assist in the fermentation of seaweeds. The topic stems from the need to consider the valorization of seaweeds due to their abundance in natural habitats as well as their use as an innovative and sustainable food. Fermentation is a traditional method that has been utilized for food preservation. It
Membrane filtration was used to concentrate proteins and decrease the salt concentration in a hydrolyzed fermentation broth. The broth was a by-product from the bacterial production and extraction of polyhydroxyalkanoates (PHA), that can be used to produce biobased plastics. 3 ultrafiltration-membranes, RC70PP, GR70PP and ETNA10PP from Alfa Laval Corporate AB, were evaluated at varying cross-flow
As the need of environmentally friendly alternatives to fossil fuels is growing bigger, so is the need for knowledge and research around possible new raw materials that could serve that pur-pose. One discussed product is biogas. Since biogas can be produced from not only food waste and wastewater residue, but from any substrate that contains fats, proteins and/or car-bohydrates, with the help of d
In past years, the demand for an indirect extraction of respiration and the interest in a joint study of respiratory and cardiac systems represented the driving forces for the development of Electrocardiogram Derived Respiration (EDR) algorithms. The main advantage of them consists in deriving a sufficiently reliable surrogate respiratory signal by only exploiting the normal electrocardiogram (ECG
Småhus avser friliggande en- och tvåbostadshus samt par-, rad- och kedjehus. Småhusbostäder är vanligt förekommande i Sverige men de senaste åren har nybyggnationen av dessa bostäder legat på en oförändrad nivå samtidigt som antalet nybyggda bostäder i flerbostadshus ökat kraftigt. Andelen nybyggda småhus har således minskat de senaste åren och bakgrunden för arbetet har därför varit att besvara fSingle-family housing is a relatively common type of housing in Sweden. Even though the demand for this type of housing is higher than the supply, the share of new construction is decreasing in favor of multi-family housing. There has been a significant increase in new housing construction as of late, however the amount of new single-family housing has remained constant. The purpose of this paper
An increase in protein alternatives is necessary to feed the rising global population healthy and sustainable food. Dairy alternatives are one way to provide more environmentally and animal-friendly products. Next to plant-based drinks (PBDs) used as milk alternatives, plant-based yoghurts (PBYs) are becoming more popular. PBYs are produced by fermenting water-based extracts of plants and are expe

This research characterized the barrier properties and transport mechanisms of multilayer films comprising polylactide (PLA), chitosan, and nanocelluloses extracted from agricultural by-products. The investigation employed complementary analytical techniques to evaluate water vapor and oxygen transport behavior, comparing cellulose nanofibers (CNF) and cellulose nanocrystals (CNC) derived from cor
