Systemic lupus erythematosus : Still a challenge for physicians

Systemic lupus erythematosus (SLE) has a complex clinical picture, and a number of defects in the immune system have been described in patients with the disease. Most organs can be involved in SLE, and in addition to the typical major organ manifestations (e.g. from kidneys and the central nervous system), early cardiovascular disease is a major determinant of prognosis. Several important findings

The poison dart frogs Oophaga granulifera and Oophaga pumilio are distributed in Nicaragua (only O. pumilio), Costa Rica and Panama. The ecology and behavior of both species has attracted scientifc attention for several reasons. These frogs exhibit toxicity in combination with bright coloration and diversification into different color morphs. Moreover, they display highly aggressive and territoria

Acoustic focusing of microparticles in two-phase systems - Towards cell enrichment or medium exchange in droplets

We present a method to first laterally position microparticles inside droplets by acoustic forces and then split the droplet into three daughter droplets to achieve a 2+fold enrichment of microparticles inside the center droplet. We show that acoustic forces can be applied to both manipulate polystyrene beads (5 μm) and red blood cells inside droplets. The presented technology opens up for develop

Early- versus Late-Onset Alzheimer’s Disease—Differences in Functional Impairment.

Background: Persons with clinical onset of Alzheimer’s disease (AD) before 65 years of age are diagnosed with early-onset AD (EOAD). The prevalence of EOAD is low, but varies among studies from 6% to 16%. Most individuals with EOAD are still working, have an active social life, and might have children living at home. Therefore, the consequences of being diagnosed early with a disease that implies

RIFM fragrance ingredient safety assessment, 3,7-dimethyl-1,6-nonadien-3-ol, CAS Registry Number 10339-55-6

The use of this material under current conditions is supported by existing information. This material was evaluated for genotoxicity, repeated dose toxicity, developmental and reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, as well as environmental safety. Data from the suitable read across analog linalool (CAS # 78-70-6) show that this mate

RIFM fragrance ingredient safety assessment, benzyl butyrate, CAS Registry Number 103-37-7

The use of this material under current use conditions is supported by the existing information. This material was evaluated for genotoxicity, repeated dose toxicity, developmental and reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, as well as environmental safety. Data from the suitable read across analog benzyl acetate (CAS # 140-11-4) show

Worldwide trends in diabetes since 1980 : A pooled analysis of 751 population-based studies with 4.4 million participants

Background: One of the global targets for non-communicable diseases is to halt, by 2025, the rise in the age standardised adult prevalence of diabetes at its 2010 levels. We aimed to estimate worldwide trends in diabetes, how likely it is for countries to achieve the global target, and how changes in prevalence, together with population growth and ageing, are aff ecting the number of adults with d

Input, behaviour and distribution of multiple elements in abiotic matrices along a transect within the Okavango Delta, northern Botswana

Wetlands fed by rivers can be a sink for elements depending on elemental concentrations, wetland hydrology, geochemistry, vegetation and climate. In the case of the Okavango Delta, northern Botswana, the outflow discharge is a small fraction (2–5%) of the inflow. This has strong potential consequences for the Delta, as it strongly affects element cycling and storage within the Delta. We estimated

Vertical III-V nanowire MOSFETs, TFETs, and CMOS-Gates on Si : Processing in 3D

III-V MOSFETs are candidates for extension of the scaling roadmap beyond 10 nm. In the vertical direction, the requirements on gate-length scaling is less stringent and vertical III-V nanowire FETs are thus attractive for high density and low-power applications. While growth in the vertical direction allows flexibility in heterostructure combination and eases the path for integration on Si substra

Immune checkpoint therapy for pancreatic cancer

Novel treatment modalities are necessary for pancreatic cancer. Immunotherapy with immune checkpoint inhibition has shown effect in other solid tumors, and could have a place in pancreatic cancer treatment. Most available clinical studies on immune checkpoint inhibitors for pancreatic cancer are not yet completed and are still recruiting patients. Among the completed trials, there have been findin

Nitric oxide synthase inhibition causes acute increases in glomerular permeability in vivo, dependent upon reactive oxygen species

There is increasing evidence that the permeability of the glomerular filtration barrier (GFB) is partly regulated by a balance between the bioavailability of nitric oxide (NO) and that of reactive oxygen species (ROS). It has been postulated that normal or moderately elevated NO levels protect the GFB from permeability increases, whereas ROS, through reducing the bioavailability of NO, have the op

The role of regions for different forms of business organizations

The evidence for associations between area characteristics and entrepreneurship is fairly consistent in most studies. These studies, however, have disregarded the fact that the areas might be constructs that have no effect on the individual differences in entrepreneurship and, furthermore, have conflated entrepreneurship and sole proprietorship, disregarding the impact of area constructs on differ

Annexin A2 antibodies but not inhibitors of the annexin A2 heterotetramer impair productive HIV-1 infection of macrophages in vitro

During sexual transmission of human immunodeficiency virus (HIV), macrophages are initial targets for HIV infection. Secretory leukocyte protease inhibitor (SLPI) has been shown to protect against HIV infection of macrophages through interactions with annexin A2 (A2), which is found on the macrophage cell surface as a heterotetramer (A2t) consisting of A2 and S100A10. Therefore, we investigated po

Innovation and industrial renewal in Sweden, 1970–2007

This study explores the question of whether the Swedish innovation output of the 1970s and 1980s (and the following decades) indicates structural lock-in or renewal. It is motivated by inconsistent explanations in the current literature about the relation between the economic slowdown and subsequent industrial renewal, as well as a lack of research focusing, in this context, on the primary driver

Antagonism of EGFR and HER3 enhances the response to inhibitors of the PI3K-Akt pathway in triple-negative breast cancer

Both abundant epidermal growth factor receptor (EGFR or ErbB1) and high activity of the phosphatidylinositol 3-kinase (PI3K)-Akt pathway are common and therapeutically targeted in triple-negative breast cancer (TNBC). However, activation of another EGFR family member [human epidermal growth factor receptor 3 (HER3) (or ErbB3)] may limit the antitumor effects of these drugs. We found that TNBC cell
