The Notch signaling pathway is involved in several lineage commitment and differentiation events. One of these is fate determination of the common lymphoid progenitor, promoting T-cell development at the expense of B-cell differentiation. It has been suggested that this process relies on Notch's ability to inhibit E proteins, which are crucial for early B-cell development. Here, we report that Not
Objectives: It was the aim of this study to assess educational needs and priorities in genetics amongst non-genetic health professionals. Methods: The methods used included website reviews and direct contact with individuals and organisations involved in health professional education. Results and Conclusions: Health professional education and training differed in structure with wide variation in t
Nearly half of mammalian genomes are derived from ancient transposable elements (TEs). We analyzed the prevalence of TEs in untranslated regions of human and mouse mRNAs and found evidence suggesting that TEs affect the expression of many genes through the donation of transcriptional regulatory signals. Furthermore, we found that recently expanded gene classes, such as those involved in immunity o
This study investigated: (a) the cost and change in hospitalizations related to alcohol misuse for the healthcare sector and (b) the effect of distance to the border on alcohol-related hospitalization costs. The first objective was analyzed using descriptive statistics and the second using ordinary least squares regression on aggregated municipality data. The total cost decreased marginally during
A dynamic, process-oriented, deterministic and phosphorus-based model was developed to simulate the food web dynamics of Lake Ringsjön, in particular the long-term effects of biomanipulation in terms of reduction of omnivorous fish. The model contains 14 state variables, each with a differential equation describing sources and sinks of phosphorus. The state variables encompass piscivorous and omni
The removal of chemical oxygen demand (COD) from wastewater containing oxalic acid was experimentally investigated using a three-phase three-dimensional electrode reactor. The experimental results show that the removal efficiency depends on the applied cell voltage, airflow, electrolysis time and the number of repeated runs. The former four factors all had a positive effect while the last factor g
BACKGROUND. Androgen deprivation is the only effective systemic therapy available for patients with prostatic carcinoma, but is associated with a gradual transition to a hormone-refractory prostate cancer (HRCAP) in which ligand-independent activation of the androgen receptor has been implicated. The beta(2)-adrenergic receptor (beta(2)-AR) is a well-known activator of the androgen receptor. METHO
A time domain method building on the concept of wave splitting is used to study direct wave propagation phenomena in weakly nonlinear media. The starting point is the linear wave equation with time-dependent coefficients. This means that the studied nonlinear medium in some sense has to be approximated with a nonstationary medium which changes while the wave passes through. For the nonstationary e
PIP: To determine whether bacterial vaginosis (BV) is associated with use of specific contraceptive methods, 956 women from family planning and youth clinics at 3 Swedish hospitals were enrolled in a cohort study. 131 women had at least 3 of the 4 clinical signs of BV: a homogenous gray vaginal discharge, a vaginal pH of 4.7, a positive amine test, and the presence of "clue" cells. Age at first in
This study compares the effectiveness of teaching the calculation of frontal plane QRS axis with the use of the classical versus the orderly electrocardiographic limb lead display. Eighty-three students from two environments were randomized into two groups and were taught to determine frontal plane axis with one of the methods. The accuracy and time to determine the axis were tested on 10 electroc
Background: The study was designed to determine whether a 1-year hospital-based secondary prevention programme would have any long-term effects on serum lipid levels and the use of lipid-lowering drugs in patients with coronary artery disease 4 years after referral to primary care facilities for follow-up. Design/methods: After acute myocardial infarction or coronary bypass surgery, 241 consecuti
This paper is intended to answer the question: “When is a simple dead-time compensator expected to perform better than a PID?”. The performance criterion used is the integrated absolute error (IAE). It is compared for PI and PID controllers and a simple dead-time compensator (DTC) when a step load disturbance is applied at the plant input. Both stable and integrating processes are considered. For
Dyskinesias are a major complication of long-term l-3,4-dihydroxyphenylalanine (L-DOPA) treatment in Parkinson's disease, and are believed to result from the intermittent and pulsatile supply of L-DOPA. Daily injections of L-DOPA can prime similar abnormal involuntary movements of the limb, orolingual and axial muscles in rats rendered parkinsonian by destruction of the nigrostriatal dopamine (DA)
The purpose of this study is to investigate how agile development affects collaboration in an organization. Agile processes have received interest from the software development community during the last years as they address changes, such as new customer requirements or re-prioritization of development tasks, which is important to manage in software development. Most of the research published abou
The main source of autoantigens in systemic lupus erythematosus (SLE) is most likely apoptotic material. We have previously shown that sera from SLE patients can induce apoptosis in monocytes and lymphocytes, and here we characterized mechanisms of apoptosis induced by SLE serum. SLE serum seems to induce caspase-dependent classical apoptosis since cells exposed to SLE serum displayed morphology c
Biological characteristics of virus quantitatively rescued from different cell types present in lymph nodes of HIV-1-infected individuals in various stages of their disease were determined, not including patients with AIDS defining illness. Viruses were obtained by cocultivation with donor monocyte-derived macrophages and T-lymphocytes and their biological phenotype compared to viruses obtained fr
Pt/Al2O3 catalysts with platinum contents of 0.1, 1.0 and 3.0 wt% were used for the low temperature combustion of methanol in the absence and the respective presence of a trace amount of ammonia. It is observed that ammonia inhibits the combustion of methanol, which is due to competition between methanol and ammonia for the same sites. For a fixed space velocity and without ammonia in the gas, the
