Mitochondrial dihydroorotate dehydrogenase (DHOdehase; EC 1.3.99.11) is a target of anti-proliferative, immunosuppressive and anti-parasitic agents. Here, redoxal, (2,2'-[3,3'-dimethoxy[1, 1'-biphenyl]-4,4'-diyl)diimino]bis-benzoic acid, was studied with isolated mitochondria and the purified recombinant human and rat enzyme to find out the mode of kinetic interaction with this target. Its pattern

Mitochondrially-bound dihydroorotate dehydrogenase (EC 1.3.99.11) catalyzes the fourth sequential step in the de novo synthesis of uridine monophosphate. The enzyme has been identified as or surmised to be the pharmacological target for isoxazol, triazine, cinchoninic acid and (naphtho)quinone derivatives, which exerted antiproliferative, immunosuppressive, and antiparasitic effects. Despite this

The isoxazol leflunomide (N-(4-trifluoromethylphenyl)-5-methylisoxazol-4-carboxamide) and its active metabolite A77-1726 (N-(4-trifluoromethyl)-phenyl-2-cyano-3-hydroxy-crotonic acidamide) are promising disease-modifying antirheumatic drugs now in clinical trials. The malononitrilamides MNA279 (2-cyano-3-cyclopropyl-3-oxo-(4-cyanophenyl)propionamide) MNA715(N-(4-trifluoromethyl)-phenyl-2-cyano-3-h

Mitochondrially bound dihydroorotate-ubiquinone oxidoreductase (dihydroorotate dehydrogenase, EC 1.3.99.11) catalyzes the fourth sequential step in the de novo synthesis of uridine monophosphate. Based on the recent functional expression of the complete rat dihydroorotate dehydrogenase by means of the baculovirus expression vector system in Trichoplusia ni cells, a procedure is described that allo

Mammalian dihydroorotate dehydrogenase (EC 1.3.99.11), the fourth enzyme of pyrimidine de novo synthesis is located in the mitochondrial inner membrane with functional connection to the respiratory chain. From the cDNA of rat liver dihydroorotate dehydrogenase cloned in our laboratory the first complete sequence of a mammalian enzyme was deduced. Two hydrophobic stretches centered around residues

Human mitochondrial dihydroorotate dehydrogenase (the fourth enzyme of pyrimidine de novo synthesis) has been overproduced by means of a recombinant baculovirus that contained the human cDNA fragment for this protein. After virus infection and protein expression in Trichoplusia ni cells (BTI-Tn-5B1-4), the subcellular distribution of the recombinant dihydroorotate dehydrogenase was determined by t

Mitochondrially bound dihydroorotate dehydrogenase catalyses the fourth sequential step in the de novo synthesis of uridine monophosphate. 312-bp and 983-bp regions of the human dihydroorotate dehydrogenase sequence (1496 bp) were amplified by the polymerase chain reaction, and subcloned into the expression vector pQE 32. The identity of the PCR products was verified by dideoxynucleotide sequencin

In 1962, the first thorough investigation into the expansion of the Swedish public sector was presented as a doctoral dissertation by Erik Höök. This article investigates the origin and reception of this thesis. Höök’s work has been consid ered a standard work of financial statistics. However, it attracted heavy criticism in the media and from other academics for having explained the public sector

We investigate two parallel school reforms in Sweden to assess the long-run health effects of education. One reform only increased years of schooling, while the other increased years of schooling but also removed tracking leading to a more mixed socioeconomic peer group. By differencing the effects of the parallel reforms we separate the effect of de-tracking and peers from that of more schooling.

The purpose of this paper is to increase our understanding of the governing of flood risk mitigation in advanced liberal society, through an in-depth Swedish case study. By combining social network analysis and genealogy, this paper investigates who is involved, how they organise, their modes of thinking, how they mitigate flood risk, as well as how such regime of practises have come into being. T

The aim of this study was to establish creatinine growth curves separately for males and females that can be used to adjust childhood levels of serum creatinine to corresponding adult levels. Linear regression with fractional polynomials of age as independent variable was used to construct creatinine growth curves for a reference cohort (n = 83,157 samples from Belgium and Sweden, age 2–40 years).

This article analyzes administrative practices in relation to the emergence of novel technologies. “Smart mobility” is an umbrella term used to denote the potentially disruptive changes in the transport sector relating to automatization, digitalization, and the platform economy. While this development is largely driven by industry, public administrations are engaging in a number of processes where

Despite marked development in cancer therapies during recent decades, the prognosis for advanced cancer remains poor. The conventional tumor–cell-centric view of cancer can only explain part of cancer progression, and thus a thorough understanding of the tumor microenvironment (TME) is crucial. Among cells within the TME, cancer-associated fibroblasts (CAFs) are attracting attention as a target fo

Aim: This study aimed to investigate changes in mental health among young adults participating in an integrated mental health and vocational support intervention according to the Södertälje Supported Employment and Education model. Design: A prospective longitudinal pre–post intervention study of 12 months. Methods: Instruments on depressive symptoms, quality of life, empowerment, engagement in ac

If resource intensive practices are regularly represented as conventional, these potentially become naturalised and inconspicuous consumption will increase. Understanding how representations, conventions and everyday practices interact is thus fundamental in tackling unsustainable consumption. To gain new insights into how representations, conventions and practices interact, this paper explores ho

Background: The prevalence of heart failure (HF) is rising with ageing population and constitutes a major health problem globally. A common complication of HF is pulmonary hypertension (PH) which negatively impacts survival. A pathophysiological association between HF and PH with tumorigenic processes has been suggested. We aimed to identify the plasma levels of, and the association between tumour

The aim of this study was to explore how consequences from a university-wide partnership unfolded at various levels within a university and induced intra-organizational dynamics. This was achieved via an in-depth investigation of “The Bridge,” a collaborative partnership between the young mid-range Swedish Linnaeus University (“Average Joe”) and the home furnishing retail giant IKEA, which despite

Raptors have always fascinated mankind, owls for their highly sensitive vision, and eagles for their high visual acuity. We summarize what is presently known about the eyes as well as the visual abilities of these birds, and point out knowledge gaps. We discuss visual fields, eye movements, accommodation, ocular media transmittance, spectral sensitivity, retinal anatomy and what is known about vis

Growth in the smallholder-based livestock sector, characterized by increasing number of animals, commercialization and processing of animal products have historically provided a decisive contribution to raising the incomes of farm households, and to the broader process of agricultural transformation. In this paper, we use a mixed methods approach to examine the processes of extensive and intensive

CERN operates one of the most complex particle accelerator facilities in the world. Several different hazards, including fires, are present and need to be investigated and reduced to a tolerable level. Toward this goal, CERN aims at developing a catalog containing detailed fire dynamics descriptions of combustible items present in its facilities. This paper contributes to this catalog in two ways.
