Phylogenetic analysis of 1.5 Mbp and platypus EST data refute the Marsupionta hypothesis and unequivocally support Monotremata as sister group to Marsupialia/Placentalia

The extant mammalian groups Monotremata, Marsupialia and Placentalia are, according to the ‘Theria’ hypothesis, traditionally classified into two subclasses. The subclass Prototheria includes the monotremes and subclass Theria marsupials and placental mammals. Based on some morphological and molecular data, an alternative proposition, the Marsupionta hypothesis, favours a sister group relationship

Comprehensive mutational analysis of a cohort of Swedish Cornelia de Lange syndrome patients

Cornelia de Lange syndrome (CdLS; OMIM 122470) is a rare multiple congenital anomaly/mental retardation syndrome characterized by distinctive dysmorphic facial features, severe growth and developmental delay and abnormalities of the upper limbs. About 50% of CdLS patients have been found to have heterozygous mutations in the NIPBL gene and a few cases were recently found to be caused by mutations

The Yersinia protein kinase A is a host-factor inducible RhoA/Rac-binding virulence factor.

The pathogenic yersiniae inject proteins directly into eukaryotic cells that interfere with a number of cellular processes including phagocytosis and inflammatory-associated host responses. One of these injected proteins, the Yersinia protein kinase A (YpkA), has previously been shown to affect the morphology of cultured eukaryotic cells as well as to localize to the plasma membrane following its

Microwaves From UMTS/GSM Mobile Phones Induce Long-Lasting Inhibition of 53BP1/gamma-H2AX DNA Repair Foci in Human Lymphocytes

We have recently described frequency-dependent effects of mobile phone microwaves (MWs) of global system for mobile communication (GSM) on human lymphocytes from persons reporting hypersensitivity to electromagnetic fields and healthy persons. Contrary to GSM, universal global telecommunications system (UMTS) mobile phones emit wide-band MW signals. Hypothetically, UMTS MWs may result in higher bi

Understanding the Jus Cogens Debate: The Pervasive Influence of Legal Positivism and Legal Idealism

Although, today, jus cogens is a recognized element of international law and international legal discourse alike, many issues of vital importance to a well-functioning jus cogens regime remain unsettled. The current debate centers on the following six questions: (1) What is the source of jus cogens obligations? (2) What is the role of consent in the creation and modification of jus cogens norms? (

The median hazard ratio : a useful measure of variance and general contextual effects in multilevel survival analysis

Multilevel data occurs frequently in many research areas like health services research and epidemiology. A suitable way to analyze such data is through the use of multilevel regression models (MLRM). MLRM incorporate cluster-specific random effects which allow one to partition the total individual variance into between-cluster variation and between-individual variation. Statistically, MLRM account

Protein kinase C and mouse sciatic nerve regeneration

We have studied the role of protein kinase C (PKC) in peripheral nerve regeneration by using the cultured adult mouse sciatic nerve, which displays regrowth of sensory axons under serum-free conditions. By the use of immunohistochemistry we show that one of the isoforms of PKC, PKCβ, is present in the nerve cell bodies of normal nerves and is upregulated after injury. In spite of this, the specifi

Counteracting wetland overgrowth increases breeding and staging bird abundances

Human actions have led to loss and degradation of wetlands, impairing their suitability as habitat especially for waterbirds. Such negative effects may be mitigated through habitat management. To date scientific evidence regarding the impacts of these actions remains scarce. We studied guild specific abundances of breeding and staging birds in response to habitat management on 15 Finnish wetlands.

The remarkable visual capacities of nocturnal insects : Vision at the limits with small eyes and tiny brains

Nocturnal insects have evolved remarkable visual capacities, despite small eyes and tiny brains. They can see colour, control flight and land, react to faint movements in their environment, navigate using dim celestial cues and find their way home after a long and tortuous foraging trip using learned visual landmarks. These impressive visual abilities occur at light levels when only a trickle of p

Genotyping of Staphylococcus aureus in bovine mastitis and correlation to phenotypic characteristics

Reducing the prevalence of mastitis caused by Staphylococcus aureus (S. aureus) is essential to improve animal health and reduce economic losses for farmers. The clinical outcome of acute mastitis and risk of progression to persistent mastitis can, at least to some extent, be related to genetic variants of the strain causing the infection. In the present study we have used microarrays to investiga

A Conceptual View of Enterprise Resource Planning Systems as Services

This paper brings forward a conceptual view, based on practical experiences from designing information systems as services. Viewing information systems (IS) as services is beneficial but still an unexplored approach in organizations. The aim of this exercise is to contribute to the knowledge base of IS designers and modelers. In the paper, we present an analysis of Enterprise Resource Planning (ER

SIX1 as a Novel Immunohistochemical Marker in the Differential Diagnosis of Rhabdomyosarcoma

Background: Differential diagnosis of rhabdomyosarcoma (RMS) is challenging. Sineoculis homeobox homolog 1 (SIX1) is an oncogene involved in skeletal muscle differentiation. We compared protein expression patterns of SIX1 in RMS and its most common differential diagnoses. Methods: SIX1 immunohistochemistry in 36 RMS and in 33 tumors from seven differential diagnostic subtypes were evaluated. The f

Marine PET Hydrolase (PET2) : Assessment of Terephthalate- and Indole-Based Polyester Depolymerization

Enzymatic polyethylene terephthalate (PET) recycling processes are gaining interest for their low environmental impact, use of mild conditions, and specificity. Furthermore, PET hydrolase enzymes are continuously being discovered and engineered. In this work, we studied a PET hydrolase (PET2), initially characterized as an alkaline thermostable lipase. PET2 was produced in a fusion form with a 6-h

Optical feedback control loop for the precise and robust acoustic focusing of cells, micro- and nanoparticles

Despite a long history and the vast number of applications demonstrated, very few market products incorporate acoustophoresis. Because a human operator must run and control a device during an experiment, most devices are limited to proof of concepts. On top of a possible detuning due to temperature changes, the human operator introduces a bias which reduces the reproducibility, performance and rel

Normalization of puberty and adult height in girls with Turner syndrome : results of the Swedish Growth Hormone trials initiating transition into adulthood

Objective: To study the impact of GH dose and age at GH start in girls with Turner syndrome (TS), aiming for normal height and age at pubertal onset (PO) and at adult height (AH). However, age at diagnosis will limit treatment possibilities. Methods: National multicenter investigator-initiated studies (TNR 87-052-01 and TNR 88-072) in girls with TS, age 3–16 years at GH start during year 1987–1998

Design of a national patient-centred clinical pathway for sepsis in Sweden

Background: The World Health Organization has adopted a resolution on sepsis and urged member states to develop national processes to improve sepsis care. In Sweden, sepsis was selected as one of the ten first diagnoses to be addressed, when the Swedish government in 2019 allocated funds for patient-centred clinical pathways in healthcare. A national multidisciplinary working group, including a pa

Optically pure lactic acid production from lignocellulosic biomass

Lactic acid is a platform chemical that can be used for many applications. More recently, optically pure lactic acid—L- or D-lactic acid enantiomers—have been used for the polymerisation to poly-lactic acid (PLA). The possibility of tailoring the properties of this bioplastic by adjusting the ratio of each enantiomer might help to accelerate the substitution of petroleum-based plastics with bio-ba

Integration of ground-source heat pumps in combined district heating and cooling networks: A holistic modeling framework

The integration of heat pumps in low-enthalpy district heating and cooling networks can increase the efficiency and flexibility of the network. In such systems, heat pumps are installed both locally and centrally to serve different functions. In the former case, decentralized heat pumps at each building adjust the low-network temperature to the desired supply temperature. In the latter case, a cen
