BACKGROUND: Knowledge is limited regarding the association between stem cells in histologically benign breast tissue and risk factors for breast cancer, and hence we addressed this issue in the present study. Recently, we assessed the histology of benign breast tissue from cancer and non-cancer patients for cells positive for the putative stem cell marker aldehyde dehydrogenase 1 A1 (ALDH), and th
Background and Objectives: Photodynamic therapy using 20% 5 aminolevulinic acid (5-ALA) has recently been introduced as a new tool in optical skin rejuvenation. The primary objective of this study was to optimize incubation time, the topical delivery mechanism (vehicle) and the concentration of 5-ALA by detecting the dynamic changes of normal skin after 5-ALA application. The secondary objective w
Inom nuklearmedicinen utnyttjas radioaktiva läkemedel och strålningen som sänds ut från dessa för att diagnosticera och behandla ett flertal olika sjukdomar. Det radioaktiva läkemedlet ges ofta till patienten som en intravenös injektion, och läkemedlets egenskaper i kombination med patientens fysiologi och eventuella sjukdom avgör hur läkemedlet sedan fördelas, omsätts och utsöndras från kroppen. Many nuclear medicine investigations rely on gamma-camera imaging to study and quantify the distribution of radiopharmaceuticals or radionuclides in the patient as a function of time. This is typically used for diagnostic studies of physiological functions or for calculation of absorbed doses following radionuclide therapy. In this work, computational patient models (phantoms) have been developed
Anthropogenic changes to the environment expose wildlife to many pollutants. Among these, tropospheric ozone is of global concern and a highly potent pro-oxidant. In addition, human activities include several other implications for wildlife, e.g., changed food availability and changed distribution of pathogens in cities. These co-occurring habitat changes may interact, thereby modulating the physi

Sverige saknar i dag ett särskilt konstitutionellt regelverk för hantering av allvarliga fredstida krissituationer motsvarande det som gäller vid krig och krigsfara. Erfarenheterna från covid-19-pandemin har emellertid aktualiserat frågan om den svenska konstitutionella beredskapen är tillräcklig under fredstida kriser. Mot denna bakgrund har riksdagen som vilande antagit ett grundlagsförslag om eSweden currently lacks a specific constitutional framework for managing severe peacetime crises comparable to the emergency provisions applicable in times of war or danger of war. The experiences of the COVID-19 pandemic have nevertheless raised questions regarding whether the existing constitutional framework provides sufficient capacity to respond effectively to extraordinary peacetime emergenci

Popular Abstract in Swedish Denna avhandling handlar till stora delar om fotodynamisk tumörterapi (PDT). PDT har sedan början av förra århundradet undersökts som ett tänkbart alternativ till strålningsbehandling, kirurgi och kemoterapi för behandling av cancertumörer i kroppen. Precis som namnet antyder involverar metoden en fotodynamisk reaktion. För att denna reaktion skall ske behövs tre kompoPhotodynamic therapy (PDT) as a cancer treatment modality relies on the simultaneous presence of three components; light, photosensitiser and oxygen. Once excited by the light, the photosensitiser can interact with oxygen, leading to the formation of toxic oxygen species. These reactive substances induce cellular damage within the irradiated tissue volume. PDT has been investigated for treating ma

The work within this thesis investigates Photodynamic therapy and Fluorescence imaging for therapeutics and visualization of deeply embedded lesions. Photodynamic therapy (PDT) is a cancer treatment modality that can eradicate tumors when light, a photosensible drug and oxygen are present. In recent decades there has been an interest in adapting this modality to deep-seated solid tumors. This req

Popular Abstract in Swedish Ärftliga näthinnesjukdomar med tidig debut Elektrofysiologiska och genetiska studier Ärftliga näthinnesjukdomar är den vanligaste orsaken till allvarligt synhandikapp hos unga människor i dagens Sverige. De flesta av dessa sjukdomar kan ännu inte behandlas, men vi har under de senaste åren fått allt större insikt i de bakomliggande sjukdomsmekanismerna, tack vare att Hereditary retinal degenerations are the most frequent reason for severe visual handicap among young people in Scandinavia today. In the six papers included in this thesis the phenotypic expressions, with emphasis on the electrophysiological findings, of five different juvenile hereditary retinal degenerations are described. The diagnoses have been confirmed by genetic analysis. The retinal disord
X-linked retinoschisis (XLRS) is a congenital progressive inherited retinal disease that affects the entire retina and is one of the more common causes of vision loss from retinal degeneration affecting young men,. The progression is variable but seems to be relatively stationary in the ages 6 to 25 years. Patients with XLRS lack a functional retinoschisin protein in the eye, because of mutation i
Estimates indicate that the global cancer burden may be ever-increasing. Gastric cancer is one of the major cancer forms. Despite its declining incidence, the high mortality of gastric cancer makes it the third most common cause of cancer-related death. Esophageal cancer is less common, but the incidence is increasing in parts of the world. Although some progress has been made in the treatment of
Aims: Exhaled breath particles have been explored for diagnosing different lung diseases. We recently showed in an experimental model that different cardiac output results in different particle flow rate (PFR) from the airways. Given the well-known close relationship between impaired cardiac function and respiratory failure, we hypothesized that PFR in exhaled air can be used to detect cardiac fai
Bland vilda djur finns närmast ett oräkneligt antal patogener. Dessa kan i vissa fall ge utbrott av zoonotiska sjukdomar vilket har hänt vid upprepade tillfällen under mänsklighetens historia. Men varför kan endast vissa av de patogener som normalt finns hos vilda djur infektera människor? Fågelinfluensa och West-Nile virus kan överföras från fåglar till människor medan rabies kan överföras från hParasites live on or inside their hosts and usually cause fitness loss, sometimes even lead to outbreaks of emerging infectious disease. Understanding how a parasite can infect its hosts (i.e., host specificity of the parasite) is important to both basic studies on disease evolution and the whole ecosystem health.In this thesis, I use avian haemosporidians, a group of species-rich protozoans as a
