HIV-1, HIV-2 and other Sexually Transmitted Infections in Guinea-Bissau, West Africa

Popular Abstract in Swedish Humant immunbristvirus (HIV) orsakar förvärvat immunbristtillstånd (AIDS). HIV/AIDS-epidemin har hittills innefattat över 60 miljoner människor som har infekterats och över 30 miljoner av dessa har avlidit i AIDS. HIV-infektion smittar via blod, sexuellt och från mor till barn vid graviditet eller via bröstmjölk. Vid infektion infogas virusets arvsmassa i den infekteradHIV-1 is dominating the global HIV pandemic, while HIV-2 is mainly confined to West Africa. The highest HIV-2 prevalence figures have been reported from Guinea-Bissau. While HIV-1 infection almost invariably leads to progressive immune dysfunction and AIDS, HIV-2 infection is characterised by a smaller proportion of individuals with disease progression to AIDS. In order to monitor the long-term e

The risk/no-risk rhetoric of environmental impact assessments (EIA): The case of off-shore wind farms in Sweden

Risk is a key topic in the communication between developers of infrastructure projects, permit-granting authorities, and civil society. The nature of risk communication is contested among academics, however. Whereas some scholars conceive of risk communication as a matter of effectively communicating expert knowledge on factual matters to the public, others emphasize the role of symbolic construct

Structure and Potential Cellular Targets of HAMLET-like Anti-Cancer Compounds made from Milk Components

The HAMLET family of compounds (Human Alpha-lactalbumin Made Lethal to Tumours) was discovered during studies on the properties of human milk, and is a class of protein-lipid complexes having broad spectrum anti-cancer, and some specific anti-bacterial properties. The structure of HAMLET-like compounds consists of an aggregation of partially unfolded protein making up the majority of the compound'

Temperature-responsive inclusion complex of cationic PNIPAAM diblock copolymer and gamma-cyclodextrin

Aqueous mixtures of gamma-cyclodextrin (gamma-CD) and the thermosensitive cationic diblock copolymer poly(N-isopropylacrylamide)-b-poly(3-acrylamidopropyl)trimethylammonium chloride (PNIPAAM(24)-b-PAMPTAM(+)(9)) or the PNIPAAM homopolymer PNIPAAM(47) have been investigated using various experimental methods. Solid g-CD-polymer inclusion complexes (pseudopolyrotaxanes) form at ambient temperatures

Challenging Packaging Limits and Infectivity of Phage λ

The terminase motors of bacteriophages have been shown to be among the strongest active machines in the biomolecular world, being able to package several tens of kilobase pairs of viral genome into a capsid within minutes. Yet, these motors are hindered at the end of the packaging process by the progressive buildup of a force-resisting packaging associated with already packaged DNA. In this experi

Fluorescence Time-lapse Imaging of the Complete S. venezuelae Life Cycle Using a Microfluidic Device.

Live-cell imaging of biological processes at the single cell level has been instrumental to our current understanding of the subcellular organization of bacterial cells. However, the application of time-lapse microscopy to study the cell biological processes underpinning development in the sporulating filamentous bacteria Streptomyces has been hampered by technical difficulties. Here we present a

Cultural Trauma, Ritual and Healing

In this chapter I will discuss the effects of agency loss, cultural trauma and healing, by focusing on the impact the boarding schools, the so called residential school, had and still has on contemporary Cana-dian Mi’kmaq Native identity, drawing on interviews from one of my fieldworks conducted on the island Cape Breton, Nova Scotia.

Balancing Different Environmental Effects of Forest Residue Recovery in Sweden - A Stepwise Handling Procedure

An increased use of forest fuels is important in the reduction of our dependence on fossil fuels and in attempting to mitigate climate change. However, an increased use will also result in an intensified forestry. Recovery of forest residues (logging residues and stumps) results in a higher pressure on the forest ecosystems and adds environmental effects to those already existing in conventional f

The proper way of dwelling at the Early Neolithic gathering site of Almhov in Scania, Sweden

The Early Neolithic (c. 4000–3500 BC) site of Almhov, located in southwestern Scania, Sweden, is interpreted as a gathering and feasting site, subsequently transformed into a burial site with ancestral monuments. The focus of the article is on the pit pairs and pit clusters at the site, and on the dierential distribution of artefacts and animal bones within them, thereby touching upon more general

A Study on Serum Biochemistry and Hematological Profiling of Blue Rock Pigeon (Columba livia) in Multan (Punjab, Pakistan)

Thirty wild blue rock pigeons (Columba livia) were caught from Multan city (Pakistan). Hematological values were established for total red blood cells, total white blood cells, packed cell volume, hemoglobin concentration, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, and differential leukocyte count. Serum bio chemistry values were determined for

Retinal Function after Vitrectomy

PURPOSE:: To study retinal function after vitrectomy. METHODS:: Core vitrectomy was performed in 12 rabbits under standardized conditions using a vitreous cutting rate of either 600 or 1200 cuts/min. Full-field electroretinography (ERG) and multifocal electroretinography (mfERG) were performed pre- and postoperatively. Morphologic change was monitored by immunohistochemistry directed against glial

Nutrient constraints on metabolism affect the temperature regulation of aquatic bacterial growth efficiency

Inorganic nutrient availability and temperature are recognized as major regulators of organic carbon processing by aquatic bacteria, but little is known about how these two factors interact to control bacterial metabolic processes. We manipulated the temperature of boreal humic stream water samples within 0-25 degrees C and measured bacterial production (BP) and respiration (BR) with and without i

Pregnancy and leisure time physical activity

ABSTRACT Aims: To examine associations between leisure time physical activity before and during pregnancy and preterm delivery, birth weight, and pre-eclampsia and to describe levels of physical activity prior to and during pregnancy. Furthermore to elucidate women’s experiences and views of leisure time physical activity during pregnancy in a qualitative study. Methods: Data sources were: the Aar

Gestational Diabetes Mellitus- Future risk for mother and child

Popular Abstract in Swedish Graviditetsdiabetes är diabetes som uppkommer eller först upptäcks under en graviditet. Mellan 1-14 % av alla gravida kvinnor runt om i världen drabbas av graviditetsdiabetes och i Sverige är det ungefär 2 %. I Sverige behandlas graviditetsdiabetes med kostråd och om detta inte räcker lägger man till insulinbehandling. Kända riskfaktorer för att utveckla graviditetsdiabGestational diabetes mellitus (GDM) occurs as a complication in 2% of all pregnancies in Sweden. Women with GDM have a substantial risk of developing type 2 diabetes later in life, but the risk of developing type 1 diabetes is also increased. GDM increases the risk for macrosomia and caesarean delivery. However, long term prognosis and eventual future risks for children born to mothers with a prev

Collapsed tetragonal phase in Ca(Fe1-xCox)(2)As-2 stabilized by pressure: Structural studies using single-crystal neutron diffraction

Ca(Fe1-xCox)(2)As-2 single crystals with concentration x = 0.032, 0.051, and 0.063 were investigated by means of neutron diffraction under hydrostatic pressure. The region of existence of the high-temperature tetragonal, low-temperature orthorhombic, and pressure-induced collapsed tetragonal phases have been determined and the corresponding p-T phase diagrams for the three compositions have been c
