Antioxidant and Antimutagenic Polyisoprenylated Benzophenones and Xanthones from Rheedia acuminata

Dichloromethane extract of the stem bark of Rheedia acuminata yielded three benzophenones with antioxidant activity, the new one named acuminophenone A (1), guttiferone K (2) and isoxanthochymol (3), along with the known xanthones formoxanthone C (4) and macluraxanthone (5). The structures were established through interpretation of their spectroscopic data, the stereochemistry of compounds (1) and

Explaining the Transnational Design of International Organizations

Past decades have witnessed a shift in international cooperation toward growing involvement of transnational actors (TNAs), such as nongovernmental organizations, multinational corporations, and philanthropic foundations. This article offers a comprehensive theoretical and empirical account of TNA access to IOs. The analysis builds on a novel data set, covering formal TNA access to 298 organizatio

Vanin-1 T26I polymorphism, hypertension and cardiovascular events in two large urban-based prospective studies in Swedes.

BACKGROUND AND AIMS: Vanin-1 (gene name VNN1) is an enzyme with pantetheinase activity generating the amino-thiol cysteamine which is implicated in the regulation of red-ox status through its effect on glutathione. We tested the hypothesis that the rs2294757 VNN1 T26I polymorphism could affect blood pressure (BP) levels, hypertension prevalence, and risk of incident cardiovascular events. METHODS

Physiotherapy as a promoter of sexual health.

Despite the holistic intention of physiotherapy, sexual health receives insufficient attention by physiotherapists. Sexual health is an important part of general health and well-being, which is often negatively affected by physical and psychological disorders. There are several reasons why sexual health should be addressed by physiotherapists, and this article aims to describe the role of the phys

Experimental and theoretical study of the ground-state M1 transition in Ag-like tungsten

We present an experimental and theoretical study of the F-2(5/2) -> F-2(7/2) M1 transition in Ag-like W (W27+). The experiments employed the Shanghai permanent magnet electron beam ion trap, which has been developed especially for assisting spectroscopic diagnostics of edge plasmas for magnetic fusion devices. The theoretical value was obtained using the GRASP2K set of computer codes and included

A palynological study from Sweden reveals stable terrestrial environments during Late Silurian extreme marine conditions

A palynological study of the upper Silurian Oved-Ramsasa Group in Skane, Sweden yields a well preserved spore assemblage with low relative abundances of marine microfossils. In total, 26 spore taxa represented by 15 genera were identified. The spore assemblage is dominated by long-ranging cryptospore taxa, and the trilete spore Ambitisporites avitus-dilutus. However, key-species identified include

Fruit and vegetable intake and cause-specific mortality in the EPIC study

Consumption of fruits and vegetables is associated with a lower overall mortality. The aim of this study was to identify causes of death through which this association is established. More than 450,000 participants from the European Prospective Investigation into Cancer and Nutrition study were included, of which 25,682 were reported deceased after 13 years of follow-up. Information on lifestyle,

Antimicrobial effects of helix D-derived peptides of human antithrombin III.

Antithrombin III (ATIII) is a key antiproteinase involved in blood coagulation. Previous investigations have shown that ATIII is degraded by Staphylococcus aureus V8 protease, leading to release of heparin binding fragments derived from its D helix. As heparin binding and antimicrobial activity of peptides frequently overlap, we here set out to explore possible antibacterial effects of intact and

Low production of reactive oxygen species in granulocytes is associated with organ damage in systemic lupus erythematosus

Introduction: Polymorphonuclear leukocytes (PMN) are main effector cells in the acute immune response. While the specific role of PMN in systemic lupus erythematosus (SLE) and autoimmunity is still unclear, their importance in chronic inflammation is gaining more attention. Here we investigate aspects of function, bone marrow release and activation of PMN in patients with SLE. Methods: The followi

Anti-browsing effects of birch bark extract on fallow deer

A major problem within forest industry is unwanted browsing on seedlings from mammalian herbivores. The aim of this study was to evaluate the effects of birch bark extracts as repellents towards fallow deer. Birch bark was extracted in a conventional way with ethanol as solvent at ambient temperature and with a new method, liquid CO2 extraction. An analysis of the ethanol-extracted birch bark show

The role of AIB1 and PAX2 in primary breast cancer: validation of AIB1 as a negative prognostic factor.

BackgroundThe steroid-receptor coactivator amplified in breast cancer one (AIB1) is implicated to be a prognostic factor, although the results are not unanimous. Recently its effect was suggested to be modified by paired box 2 gene product (PAX2).Patients and methodsUsing immunohistochemistry (IHC) AIB1 and PAX2 were investigated in two cohorts of early breast cancer, including systemically untrea

Biotic dynamics and carbonate microfacies of the conspicuous Darriwilian (Middle Ordovician) 'Taljsten' interval, south-central Sweden

Enclosed in the Darriwilian (Middle Ordovician) part of the reddish 'orthoceratite limestone' of Baltoscandia is a conspicuous c. 1.5 m thick unit colloquially known as the 'Taljsten' interval. It has a wide geographical distribution in the Baltoscandian paleocontinent but is particularly well exposed in south-central Sweden. The unit is characterized by its deviant gray color and beds with a mass

Bit-Serial CORDIC: Architecture and Implementation Improvements

Abstract in UndeterminedThis paper presents a new and improved bit-serial CORDIC architecture. A detailed description of the bit-serial implementation and its Control Unit is presented. It is shown that the improvement is due to a reduction of registers in the implementation and is made possible by ensuring that the angular path is calculated prior to the corresponding vector paths. In addition, t

A trade-off between perceived predation risk and energy conservation revealed by an immune challenge experiment

Energy is typically a limiting factor for animals during boreal zone winters, when low temperatures increase the cost of thermoregulation at the same times as short day-lengths and snow cover constrain foraging opportunities. Under these circumstances animals use a suite of behavioural and physiological adaptations to avoid overnight starvation. However, it is poorly understood how such strategies

Pan-vertebrate comparative genomics unmasks retrovirus macroevolution.

Although extensive research has demonstrated host-retrovirus microevolutionary dynamics, it has been difficult to gain a deeper understanding of the macroevolutionary patterns of host-retrovirus interactions. Here we use recent technological advances to infer broad patterns in retroviral diversity, evolution, and host-virus relationships by using a large-scale phylogenomic approach using endogenou

Toward Next Generation Plasma Profiling via Heat-induced Epitope Retrieval and Array-based Assays

There is a need for high throughput methods for screening patient samples in the quest for potential biomarkers for diagnostics and patient care. Here, we used a combination of undirected target selection, antibody suspension bead arrays, and heat-induced epitope retrieval to allow for protein profiling of human plasma in a novel and systematic manner. Several antibodies were found to reveal alter
