Uncharacterized side activities of enzymes can have significant negative effects on reaction products and yields. Hence, their identification and characterization is crucial for the development of successful reaction systems. Here, we report the presence of feruloyl esterase activity in CtXyn5A from Acetivibrio thermocellus besides its well-known arabinoxylanase activity for the first time. Both r

Transposable elements (TEs) are dynamically expressed at high levels in multiple human tissues, but the function of TE-derived transcripts remains largely unknown. In this study, we identify numerous TE-derived microRNAs (miRNAs) by conducting Argonaute2 RNA immunoprecipitation followed by small RNA sequencing (AGO2 RIP-seq) on human brain tissue. Many of these miRNAs originated from LINE-2 (L2) e

In this report the preparation of colloidal molecules through electrostatically driven self-assembly of spherical, thermoresponsive microgel building blocks is investigated. Colloidal molecules are of interest to the scientific community because, unlike spherical colloids, they account for anisotropic interactions that can also be found in atomic molecules. The added benet of using thermoresponsiv

Detaljerade data är avgörande vid karaktärisering av komplexa förorenade områden. I denna studie utrustar vi ett antal G360-brunnssystem med Star-Oddi milli-TD-tryckgivare i ett mestadels PCE (tetrakloretylen)- och TCE (trikloretylen)-förorenat bostadsområde i Helsingborg. Trots att dessa tryckgivare vanligtvis används inom marina undersökningar gör deras kostnad samt kompakta storlek dem av intre

Semi-natural grasslands in Scandinavia have been created by humans since many millennia ago, but the agricultural intensification in the last few centuries caused them to decline heavily. Accordingly, the biodiversity associated to these open, nutrient-poor habitats declined as well and many remnant populations are slowly declining and threatened to go extinct. In this study, I focused on declin

Nigritella miniata is an alpine orchid species disjunctly endemic to the Eastern Alps and the Southeastern Carpathians. It is thought to have arisen only once through a hybridisation event between now extinct ancestors. Questions of interest are whether N. miniata survived in few or many isolated refugia in the Eastern Alps during the Last Glacial Maximum (LGM), and their relationship with the pop

As China modernizes, its waste management capacities are put to a test. Faced by significant pressures to find a solution for growing municipal solid waste, China’s authorities have embraced waste incineration technology as a seemingly cost-efficient alternative to landfills. Against this push, significant societal opposition against the construction of waste incinerators has been mounting. Yet wh

Today wind power developers are exploring the possibilities of establishing wind turbines in forest areas, therefore improved sound prediction models for complex terrains are valuable. The Swedish model used today is only applicable for hard flat ground without any vegetation, and is not adjustable to any meteorological parameters except the wind speed. The companies DELTA, DONG Energy and EMD Int

Denna studie undersöker den rumsliga variationen i markens koldioxid-utflöde (CO2) i en boreal blandskog, huvudsakligen dominerad av tall (Pinus sylvestris L.) och gran (Picea abies L.) i ADVEX experimentsite i Norunda, centrala Sverige. Mätningar av markens CO2 gjordes i 72 collars omkring huvudtornet med hjälp av en LI-6250 infraröd gasanalysapparat kopplad till en hemmagjord mörkkammare. Medelv

Quantum refinement (QR) is an approach in which the empirical restraints used in standard structural refinement to ensure that the details of the structure, e.g. bond lengths and angles, make chemical sense are replaced by more accurate quantum mechanical calculations for a small but interesting part of the structure. QR has previously been used for X-ray and neutron crystallography, cryogenic e

Popular science: Find a suitable area for rainwater harvesting Rainwater harvesting is a technique to capture and store rainfall where it falls. The technique of water harvesting can be used for different purposes, e.g providing irrigation water, drinking water, increase groundwater recharge, and reduce flood risk. The application of rainwater harvesting is suitable in arid and semi-arid areas, w

We have engineered apolipoprotein A-I (apoA-I), a major protein constituent of high-density lipoprotein (HDL), to contain DOTA-chelated Gd(III) as an MRI contrast agent for the purpose of imaging reconstituted HDL (rHDL) biodistribution, metabolism and regulation in vivo. This protein contrast agent was obtained by attaching the thiol-reactive Gd[MTS-ADO3A] label at Cys residues replaced at four d

In the past two decades, the eddy covariance technique has been used for an increasing number of methane flux studies at an ecosystem scale. Previously, most of these studies used a closed path setup with a tunable diode laser spectrometer (TDL). Although this method worked well, the TDL has to be calibrated regularly and cooled with liquid nitrogen or a cryogenic system, which limits its use in r

In order to better address the feedbacks between climate and wetland methane (CH4) emissions, we tested several mechanistic improvements to the wetland CH4 emission model Peatland-VU with a longer Arctic data set than any other model: (1) inclusion of an improved hydrological module, (2) incorporation of a gross primary productivity (GPP) module, and (3) a more realistic soil-freezing scheme.
