Similar bleeding phenotype in young children with haemophilia A or B : A cohort study

The bleeding phenotype has been suggested to differ between haemophilia A and B. More knowledge on the bleeding phenotype at initiation of treatment is important to optimize patient care. The aim of this study was to investigate the severity of the bleeding phenotype and the variation in bleeding in children with severe or moderate haemophilia A and B. Consecutive, previously untreated patients wi

The impact of prenatal diagnosis on the incidence of haemophilia in Sweden

Summary A demographic survey was made of all children (n= 137) born with severe or moderate haemophilia in Sweden during the period 1970‐92. Bn addition, all prenatal diagnoses (n= 86) performing during the period were evaluated. The annual incidence of severe and moderate haemophilia, having remained constant for decades, increased from 0.78/10,000 males in the 1970s to 1.34 in the 1980s, levelli

Ideology, politics and war violence as sources of forced migrations

The symbolic order of discourse of ideology actually enables the existence and reproduction of violence. Mass crimes on civilians may become normalized and widely accepted if perpetrators of violence who exert violence and those who implicitly and explicitly support it believe that exertion of violence on others is justified by belief in some symbolic higher order. Many current examples of justifi

Concentration Camp Rituals: An Extreme Case of Insecurity

Reason(s) for writing and research problem(s): This article analyzes the experiences retold by former concentration camp detainees who were placed in concentration camps like civilians at the beginning of the Bosnian war in the 1990s. Aims of the paper (scientific and/or social): The article aims to describe the recounted social interaction rituals after time spent in a concentration camp as well

Models of breast morphogenesis based on localization of stem cells in the developing mammary lobule

Characterization of normal breast stem cells is important for understanding their role in breast development and in breast cancer. However, the identity of these cells is a subject of controversy and their localization in the breast epithelium is not known. In this study, we utilized a novel approach to analyze the morphogenesis of mammary lobules, by combining one-dimensional theoretical models a

Growth hormone is secreted by normal breast epithelium upon progesterone stimulation and increases proliferation of stem/progenitor cells

Using in vitro and in vivo experimental systems and in situ analysis, we show that growth hormone (GH) is secreted locally by normal human mammary epithelial cells upon progesterone stimulation. GH increases proliferation of a subset of cells that express growth hormone receptor (GHR) and have functional properties of stem and early progenitor cells. In 72% of ductal carcinoma in situ lesions, an

Aldehyde dehydrogenase and estrogen receptor define a hierarchy of cellular differentiation in the normal human mammary epithelium

INTRODUCTION: Although estrogen and progesterone play a key role in normal mammary development and in breast cancer, the potential for proliferation and lineage differentiation as well as origin of cells that express the estrogen receptor (ER) in normal breast epithelium are not known. Some evidence suggests that normal human mammary stem/progenitor cells are ER-, but the identity of these cells a

A novel model of dormancy for bone metastatic breast cancer cells

Mortality of patients with breast cancer is due overwhelmingly to metastatic spread of the disease. Although dissemination is an early event in breast cancer, extended periods of cancer cell dormancy can result in long latency of metastasis development. Deciphering the mechanisms underlying cancer cell dormancy and subsequent growth at the metastatic site would facilitate development of strategies

East African Social Sciences and Humanities Publishing: A Handmade Bibliometrics Approach

For Eastern Africa, very little information about the SSH knowledge production can be found from a European perspective. Adequate indicators like information-rich bibliographic databases that cover East-Africa-based journals and book publishers are lacking. This research in progress explores their indexing situation in detail, their development, which is closely connected to political history, the

A robust decentralized control for channel sharing communication

We consider the problem of controlling the transmission rate in a communication network where each node adjusts its own transmission rate exclusively based on the physical medium occupation (the band occupancy of the aggregate complementary nodes). We show how to design a decentralized control for maximizing both band occupancy and fairness. If the network is fully connected, the problem admits a

A convex programming approach to the inverse kinematics problem for manipulators under constraints

We propose a novel approach to the problem of inverse kinematics for possibly redundant planar manipulators. We show that, by considering the joints as point masses in a fictitious gravity field, and by adding proper constraints to take into account the length of the links, the kinematic inversion may be cast as a convex programming problem. Convex constraints in the decision variables (in particu

The Smallest Eigenvalue of the Generalized Laplacian Matrix, with Application to Network-Decentralized Estimation for Homogeneous Systems

The problem of synthesizing network-decentralized observers arises when several agents, corresponding to the nodes of a network, exchange information about local measurements to asymptotically estimate their own state. The network topology is unknown to the nodes, which can rely on information about their neighboring nodes only. For homogeneous systems, composed of identical agents, we show that a

Model-Free Plant Tuning

Given a static plant described by a differentiable input-output function, which is completely unknown, but whose Jacobian takes values in a known polytope in the matrix space, this paper considers the problem of tuning (i.e., driving to a desired value) the output, by suitably choosing the input. It is shown that, if the polytope is robustly non-singular (or has full rank, in the non-square case),

Stability analysis of an artificial biomolecular oscillator with non-cooperative regulatory interactions

Oscillators are essential to fuel autonomous behaviours in molecular systems. Artificial oscillators built with programmable biological molecules such as DNA and RNA are generally easy to build and tune, and can serve as timers for biological computation and regulation. We describe a new artificial nucleic acid biochemical reaction network, and we demonstrate its capacity to exhibit oscillatory so

Broken Data : Broken World

In a world where predictive big data analytics and data driven policy and design are increasingly prevalent, the concept of broken data seeks to interrogate and disrupt the possibilities associated with these trends. Concepts of breakage, damage and repair, and recent literatures about ‘broken world’ type theories, offer us an alternative starting point: what are the implications of putting these
