Exporting Sexual and Reproductive Values - A study on the existence of U.S. SRHR politics in international AIDS relief and prevention aid in Africa

This thesis examines the ideologies and moral values regarding sexuality and gender within the United States national realm of Sexual and Reproductive Health and Rights (SRHR); and furthermore what how these ideologies and morals are translated into development policy. Through the method interrogative insertion, I have explored in the U.S. President´s Emergency Plan for AIDS Relief (PEPFAR). And t

Analysis of vibrations in high-tech facility

MAX-lab is a national synchrotron radiation facility in Lund. Nowadays, the MAX project consist of three facilities (three storage rings). A new storage ring is needed to improve material science, such as nanotechnology. MAX IV, also in Lund, will be 100 times more efficient than already existing synchrotron radiation facilities. The storage ring is controlled by a large number of magnets that are

On the Motivation to Help: Victim Information, Proportion Dominance and Group Affiliation Systematically Explored

There are 3 factors that have a large impact on the motivation to help a victim. 1.) A higher willingness to help an identified, than a non-identified victim. 2.) A preference for saving a large percentage of a group at risk in comparison to only considering the total number of saved victims. 3.) A victim closer to the helpers in-group elicits a higher motivation to help. In previous studies only

Absorbed dose distributions in the vicinity of high-density materials in head and neck radiotherapy A quantitative comparison between measurements, Monte Carlo simulations and treatment planning system

Varje år diagnostiseras i Sverige ungefär 1100 personer med cancer i huvudhalsregionen. Typiska diagnoser är tungcancer, läppcancer och cancer i struphuvudet. I och runt om munhålan finns det stora skillnader i densitet mellan till exempel vävnad och tänder och vävnad och tandlagningar. I detta arbete så har effekterna av ett antal olika tandlagningsmaterial på dosberäkningarna undersökts. För a"Introduction: Around 1.000 people are diagnosed with head and neck cancer in Sweden every year. Radiotherapy is often used to treat these tumors. When irradiating patients in the head and neck area there are some problems. One of these problems is the large difference in density between the oral tissue and dental materials. Another problem is the image artifacts due to high-density materials

Monte Carlo Simulations of a Clinical PET system using the GATE Software

Monte Carlo-simuleringar har fått en ökad betydelse som forskningsverktyg inom nuklearmedicinsk bildgivning eftersom man på ett mycket kontrollerat sätt kan studera nästan vad man vill. I denna studie har datorsimuleringar av ett PET-system gjorts med ett program som heter GATE. PET (Positron Emission Tomography) är en nuklearmedicinsk bildgivningsteknik som används mer och mer inom sjukvården sIntroduction: Monte Carlo simulation is a powerful tool in research in the field of nuclear medicine imaging and there is a wide area of applications. The purpose of this work was (1) to understand the basics of the Monte Carlo simulation software Geant4 Application for Tomographic Emission (GATE); (2) to create a model of Philips Gemini TF PET/CT system; (3) to run a number of simulations to comp

Intra-aneurysm Sac Pressure in Patients with Unchanged AAA Diameter after EVAR.

OBJECTIVE: To study intra-aneurysm sac pressure and subsequent abdominal aortic aneurysm (AAA) diameter changes in patients without endoleaks that remain unchanged in AAA diameter more than 1 year after endovascular aneurysm repair (EVAR). METHODS: A total of 23 patients underwent direct intra-aneurysm sac pressure (DISP) measurements 16 months (IQR: 14-35 months) after EVAR. Tip-pressure sensors

Cardiovascular efficacy and safety of bococizumab in high-risk patients

Background: Bococizumab is a humanized monoclonal antibody that inhibits proprotein convertase subtilisin-kexin type 9 (PCSK9) and reduces levels of low-density lipoprotein (LDL) cholesterol. We sought to evaluate the efficacy of bococizumab in patients at high cardiovascular risk. Methods: In two parallel, multinational trials with different entry criteria for LDL cholesterol levels, we randomly

Downregulation of growth hormone in postural orthostatic tachycardia syndrome: insights from the SYSTEMA cohort

Background Postural orthostatic tachycardia syndrome (POTS) is a variant of cardiovascular autonomic disorder occurring predominantly in young women. POTS is characterized by an excessive heart rate increase when assuming upright posture accompanied by symptoms of orthostatic intolerance. The pathophysiology of POTS has not been fully established and is believed to be multifactorial. Purpose We a

CYP27A1 expression is associated with risk of late lethal estrogen receptor-positive breast cancer in postmenopausal patients

Background: 27-Hydroxycholesterol (27HC) stimulates estrogen receptor-positive (ER+) breast cancer (BC) progression. Inhibiting the sterol 27-hydroxylase (CYP27A1) abrogates these growth-promoting effects of 27HC in mice. However, the significance of CYP27A1 expression on BC biology and prognosis is unclear. Methods: Intratumoral CYP27A1 expression in invasive BC was measured by immunohistochemist

Percutaneous Coronary Intervention for Vulnerable Coronary Atherosclerotic Plaque

Background: Acute coronary syndromes most commonly arise from thrombosis of lipid-rich coronary atheromas that have large plaque burden despite angiographically appearing mild. Objectives: This study sought to examine the outcomes of percutaneous coronary intervention (PCI) of non–flow-limiting vulnerable plaques. Methods: Three-vessel imaging was performed with a combination intravascular ultraso

Alzheimer's pathology targets distinct memory networks in the ageing brain

Alzheimer's disease researchers have been intrigued by the selective regional vulnerability of the brain to amyloid-β plaques and tau neurofibrillary tangles. Post-mortem studies indicate that in ageing and Alzheimer's disease tau tangles deposit early in the transentorhinal cortex, a region located in the anterior-temporal lobe that is critical for object memory. In contrast, amyloid-β pathology

Ligand binding and functional effects of systematic double D-amino acid residue substituted neuropeptide Y analogs on Y1 and Y2 receptor types

In order to identify the signal epitopes of the neuropeptide Y (NPY) molecule, the conformation of the NPY molecule was pertubated by a systematic double D-amino acid replacement of neighbouring residues. These NPY-analogs were examined for receptor affinity and on biological activity. The rat cerebral cortex and hippocampus were used for binding characteristics on Y1 and Y2 binding sites, respect

COL1A1 Sp1 polymorphism predicts perimenopausal and early postmenopausal spinal bone loss

Genetic factors play an important role in the pathogenesis of osteoporosis but the genes that determine susceptibility to poor bone health are defined incompletely. Previous work has shown that a polymorphism that affects an Spl binding site in the COLIA1 gene is associated with reduced bone mineral density (BMD) and an increased risk of osteoporotic fracture in several populations. Data from cros

Sources of parent-offspring resemblance for major depression in a national Swedish extended adoption study

Importance: Twin studies have assessed sibling resemblance for major depression (MD) but cannot address sources of resemblance across generations. Objective: To clarify the relative importance of genetic and rearing effects on the parent-offspring resemblance for MD. Design: This Swedish population register-based study examined parents and children from the following 5 family types: intact (2 041

Randomized Trial of Sacroiliac Joint Arthrodesis Compared with Conservative Management for Chronic Low Back Pain Attributed to the Sacroiliac Joint

BACKGROUND: Sacroiliac joint pain is increasingly recognized as a cause of low back pain. We compared the safety and effectiveness of minimally invasive sacroiliac joint arthrodesis using triangular titanium implants and conservative management in patients with chronic sacroiliac joint pain. METHODS: This study was a prospective, multicenter randomized controlled trial of adults with chronic sacro

Risk of complications in patients with conservatively managed ovarian tumours (IOTA5) : a 2-year interim analysis of a multicentre, prospective, cohort study

Background: Ovarian tumours are usually surgically removed because of the presumed risk of complications. Few large prospective studies on long-term follow-up of adnexal masses exist. We aimed to estimate the cumulative incidence of cyst complications and malignancy during the first 2 years of follow-up after adnexal masses have been classified as benign by use of ultrasonography. Methods: In the

Wearable comfort and performance expectancy predict user acceptance of a sensor-based home lighting system

The aim was to evaluate an early prototype of a personalised home lighting system comprising body-worn loggers, a mobile phone, and LED-based lighting with variable intensity and colour temperature. A convenience sample (N = 28, 50% female) wore the devices for 24 hours in the field and were given a demonstration of the lighting system components in a full-scale model of a studio apartment.
