  1. 1. Intracranial Arachnoid Cysts. Epidemiology, Morphology and Surgical Outcome

    Författare :Katrin Rabiei; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Arachnoid cysts; Cyst morphology; Epidemiology; Headache; Surgical outcome;

    Sammanfattning : Background: Intracranial arachnoid cysts (AC) are malformations of the arachnoid membrane. They may cause symptoms, either by obstruction of the CSF flow or by compression of adjacent neural tissues. LÄS MER

  3. 2. Overcoming the Barriers of Fine-Needle Aspiration

    Författare :Filipe Marques; Niclas Roxhed; Heikki J. Nieminen; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cysts; Cystic fluid; Pancreatic Cancer; Fine-needle Aspiration; Early diagnosis; Surgical instruments; Nitinol; Absorbable sutures; Loop brush; Cythopathology; Rapid on-site evaluation; Microfluidics; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Cysts, closed sac-like structures filled with fluid or air, can form anywhere in the body. In the majority of cases, cysts are benign (not cancerous). However, these structures can also be precursors of cancer, pointing to the location where cancer can originate. LÄS MER

  5. 4. The Greenhouse - Icehouse Transition : a dinoflagellate perspective

    Författare :Caroline A. van Mourik; Henk Brinkhuis; Malgorzata Moczydlowska-Vidal; Stockholms universitet; []
    Nyckelord :Eocene - Oligocene; dinoflagellate cysts; biostratigraphy; paleoecology; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Through the analysis of the stratigraphic and spatial distribution of organic walled dinoflagellate cysts (dinocysts) from climatologically and oceanographically key sites, this project aims to contribute to a better understanding of the Eocene-Oligocene (E/O) environmental changes and their timing. A central issue is to identify the global environmental changes which are responsible for the Eocene cooling and its underlying mechanisms with the focus on the Oligocene isotope-1 (Oi-1) event, thought to mark the onset of major Antarctic glaciation.

  7. 5. Early stage inflammation and cancer as reflected in the gastrointestinal mucus composition: implications for diagnosis, prognosis and pathogenesis

    Författare :Karolina S. Jabbar; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mucus; Mass spectrometry; MUC2; MUC5AC; IPMN; Pancreatic cysts; Ulcerative colitis; IBS; Brachyspira;

    Sammanfattning : Mucus covers our inner interfaces towards the environment, providing protection while enabling vital interaction with the outside world. The mucus is built around mucin proteins, which are important for our defences against infection and inflammation, but may also contribute to carcinogenesis and tumour progression. LÄS MER
