Lipid-filled macrophages (foam cells) are a defining feature of atherosclerotic plaques. Foam cells contain lipid dro plet- associated proteins that in other cell types regulate lipid turnover. In foam cell such proteins may directly affect lipid droplet formation and lipid efflux. Differentiated primary human monocytes or THP-1 cells were lipid loaded by incubation with aggregated low density lip
Popular Abstract in Swedish Universitet och högskolor har i kölvattnet av ett framväxande kunskapssamhället hamnat under kraftig institutionell press från en förändrad nationell forskningspolitik, de forskningsfinansierande aktörernas förändrade strategier och en snabb och omvälvande vetenskaplig dynamik. Avhandlingen handlar om hur Lunds universitet har reagerat på och hanterat dessa förändringspIn the wake of an emerging knowledge society, universities around the world have come under severe institutional pressure from changing national research policies, financing organizations´ new strategies and turbulent research dynamics. This study examines how Lund University in Sweden manages these institutional pressures. The study explores how the university leadership ? rector and the governin
Today, cognitive impairment can be successfully treated with acetylcholine esterase inhibitors (AChE-I) in many, but not all, patients with Alzheimer's disease (AD). To investigate the relation between tacrine treatment, inheritance of ApoE epsilon4 alleles, and rate of progression, the differences in MMSE and CIBIC scores (efficacy parameters) after 6 and 12 months of tacrine (an AChE-I) treatmen
Deep brain stimulation is an accepted technique for the treatment of Parkinson's disease. Deep brain stimulation affects the electrical functions of neurons and several explanations are available to describe this treatment modality. Such as depolarization blockade, synaptic inhibition, synaptic depression and stimulation induced modulation of pathological network activity. An electrical impedance
Dermatofibrosarcoma protuberans (DFSP) is a cutaneous tumour of borderline malignancy, the cytogenetic features of which include the translocation t(17;22)(q22;q13) or, more commonly, supernumerary ring chromosomes containing material from 17q22 and 22q13. These rearrangements result in the COL1A1/PDGFB fusion gene. Here, we describe a case of DFSP displaying a ring chromosome 5 together with a la
Health promotion has become a widespread concept, although little empirical research as to its importance and outcome has been performed in the mental health field. The aim of the present study was to investigate the construct validity of a newly developed Health Promotion Intervention Questionnaire, intended to measure patients' subjectively experienced health-promoting interventions within menta
Background: Little is known regarding vitamin D deficiency (VDD) in African populations and in tuberculosis (TB) patients. VDD has been shown to be associated with TB. Objective: We aimed to compare the degree of vitamin D insufficiency (VDI) and VDD in TB patients and healthy adult controls in a West African population. Design: An unmatched case-control study was performed at a Demographic Survei
Popular Abstract in Swedish De flesta svenskar har nog upplevt hur skönt det kan värma i solen en klar vinterdag, trots att termometern visar minusgrader. Eller hur kallt det känns på ryggen en sommarkväll fastän man så sitter så nära en eld att det nästan bränns. Båda erfarenheterna beror på värmestrålning som kan värma oss utan att luften omkring oss är varm. Värmestrålningen från brasan når barInfrared (IR) dryers are widely used in the paper industry, mainly in the production of coated paper grades. The thesis deals with various aspects of heat transfer and energy use in infrared heaters and dryers as employed in the paper industry. Both gas-fired and electric IR dryers are considered and compared. The thesis also provides an introduction to infrared heaters and infrared drying, includ
This article deals with male and female sex and gender roles in a native Hawaiian context, focusing particularly on lesbians. The article's point of departure is that it is the individual who decides the norms and rules of his/her sexual and social behaviour, implying an inequadecy with models where the focus is on different "cultural" and "social" forms for modelling such behaviour. One important
The stage-specific embryonic antigen 4 (SSEA4) is commonly used as a cell surface marker to identify the pluripotent human embryonic stem (ES) cells. Immunohistochemistry on human embryonic central nervous system revealed that SSEA4 is detectable in the early neuroepithelium, and its expression decreases as development proceeds. Flow cytometry analysis of forebrain-derived cells demonstrated that
A polymerase chain reaction for the specific detection of mycobacteria belonging to the Mycobacterium tuberculosis complex was developed. Using a single primer pair derived from the nucleotide sequence of protein antigen b of M. tuberculosis, we achieved specific amplification of a 419-base-pair DNA fragment in M. tuberculosis and M. bovis. After DNA was extracted from mycobacteria by using a simp
The essential spectrum of singular matrix differential operator determined by the operator matrix (-d/dx rho(x)d/dx + q(x) d/dx . beta/x - beta/x . d/dx m(x)/x(2))) is studied. It is proven that the essential spectrum of any self-adjoint operator associated with this expression consists of two branches. One of these branches (called regularity spectrum) can be obtained by approximating the operato
Nocturnal moths often use sex pheromones to find mates and ultrasonic hearing to evade echolocating bat predators. Male moths, when confronted with both pheromones and sound, thus have to trade off reproduction and predator avoidance depending on the relative strengths of the perceived conflicting stimuli. The ultrasonic hearing of Plodia interpunctella was investigated. A threshold curve for evas
The zinc-binding protein semenogelin I is the major structural component of the gelatinous coagulum that is formed in freshly ejaculated semen. Semenogelin I is a rapidly evolving protein with a primary structure that consists of six repetitive units, each comprising approximately 60 amino acid residues. We studied the secondary and tertiary structure of semenogelin I by circular dichroism (CD) sp
