All ethnic groups have norms and values according to which one is expected to behave. Immigrants in particular have personal networks that simultaneously consist of co-ethnics and friends of a different ethnic background. As a consequence, they may be accustomed to the behavior, norms, and values of their own ethnic group, and also be expected to behave according to those of another ethnic group.
Survivors of poliomyelitis often develop increased or new symptoms decades after the acute infection, a condition known as post-polio syndrome (PPS). The condition affects 20-60% of previous polio patients, making it one of the most common causes of neurological deficits worldwide. The underlying pathogenesis is not fully understood and accurate diagnosis is not feasible. Herein we investigated wh
Statins are inhibitors of the rate-limiting step of cellular cholesterol synthesis. In vitro and in vivo studies suggest that statins have anti-inflammatory properties independent of their cholesterol-lowering effects. These observations prompted us to examine the effects of pravastatin (50 mgr; M) and native or oxidized low density lipoprotein (nLDL or oxLDL) (50 mgr; g ml(minus sign1)) on primar
Hormonal replacement therapy (HRT) is generally regarded as first choice for pharmacological prevention of osteoporosis in women. We reviewed recent studies of HRT regimens and selective oestrogen receptor modulators (SERMs), including controlled trials of at least one-year duration published since 1995 until February 2000 providing data on bone mineral density (BMD) or fractures. Natural and synt
Acute myeloid leukemia (AML) is most common in the elderly, and most elderly are thought to be unfit for intensive treatment because of the risk of fatal toxicity. The Swedish Acute Leukemia Registry covers 98% of all patients with AML (non-acute promyelocytic leukemia) diagnosed in 1997 to 2005 (n = 2767), with a median follow-up of 5 years, and reports eligibility for intensive therapy, performa
The transmembrane protein Dystroglycan is a central element of the dystrophin-associated glycoprotein complex, which is involved in the pathogenesis of many forms of muscular dystrophy. Dystroglycan is a receptor for multiple extracellular matrix (ECM) molecules such as Laminin, agrin and perlecan, and plays a role in linking the ECM to the actin cytoskeleton; however, how these interactions are r
The Grebenka flora, from the main exposure of the Albian-Cenomanian Krivorechenskaya Formation in northeastern Russia, represents a range of plant communities from pioneer to mature forest that grew close to the mid-Cretaceous North Pole (> 72degreesN). The diversity of this flora is dominated by angiosperms followed by conifers, ferns and other plant groups. The age is constrained by Ar-40/Ar-39
Lymphopenia is due to a frameshift mutation in Gimap5 on rat chromosome 4 and is linked to type 1 diabetes in the diabetes prone (DP) BB rat. The hypothesis that bone marrow derived cells confer the lymphopenia phenotype was tested by reciprocal bone marrow transplantation in 40-day-old lethally irradiated diabetes resistant (DR) congenic DR.lyp/lyp (lymphopenia and diabetes) and DR.+/+ (no lympho
The monoclonal gammopathies are a group of disorders associated with monoclonal proliferation of plasma cells. The characterization of specific entities is an area of difficulty in clinical practice. The International Myeloma Working Group has reviewed the criteria for diagnosis and classification with the aim of producing simple, easily used definitions based on routinely available investigations
In 1993-1995 artificial nests with attached model eggs were put into territories that were known to have been occupied by male great reed warblers, Acrocephalus arundinaceus, in previous years. Because the eggs were made of soft plasticine, predators left peckmarks in them and this enabled us to identify predators by comparing peckmarks with reference marks made by Various species. Previous field
We examined the relation between the islet NO system and islet hormone secretion induced by either the non-glucose nutrient alpha-ketoisocaproic acid (KIC) or, in some experiments, glucose. KIC dose dependently stimulated insulin but inhibited glucagon secretion. In a medium devoid of any nutrient, the NO synthase (NOS)-inhibitor N(G)-nitro-L-arginine methyl ester (L-NAME) induced an increase in b
The most abundant helix type in proteins is the alpha-helix, accounting for about 31% of amino acid secondary structure states, while the 3(10)-helix accounts for about 4%. The pi-helix appears to be extremely rare and is considered to be unstable. Existing secondary structure definition methods find very few within the Protein Data Bank. Using an improved pi-helix definition algorithm to search a
Aim Understanding the driving forces and mechanisms of changes in past plant distribution and abundance will help assess the biological consequences of future climate change scenarios. The aim of this paper is to investigate whether modelled patterns of climate parameters 6000 years ago can account for the European distribution of Fagus sylvatica at that time. Consideration is also given to the ro
The A (1)Sigma(+) potential energy curve of AgH is studied by means of the second-order multistate multireference perturbation theory including the spin-orbit and relativistic effects. The anomalous behavior of the vibrational energy levels observed in experiment is reproduced well by theory. An analysis of the A (1)Sigma(+) wave function shows that at the internuclear distance of 4-6 Angstrom, a
In order to understand the state of test process practices in the software industry, we have conducted a qualitative survey, covering software development departments at 11 companies in Sweden of different sizes and application domains. The companies develop products in an evolutionary manner, which means either new versions are released regularly, or new product variants under new names are relea
Objective Most epidemiologic studies have suggested an increased risk of breast cancer with increasing alcohol intake. Using data from 274,688 women participating in the European Prospective Investigation into Cancer and Nutrition study (EPIC), we investigated the relation between alcohol intake and the risk of breast cancer. Methods Incidence rate ratios (IRRs) based on Cox proportional hazard mo
The mobilization of fatty acids from rat and human fat cells is selective according to molecular structure, and notably carbon atom chain length. This study aimed at examining whether the release of individual fatty acids from triacylglycerols (TAG) by hormone-sensitive lipase (HSL) plays a role in the selectivity of fatty acid mobilization. Recombinant rat and human HSL were incubated with a lipi
