  1. 11. Spatial and temporal regulation of neural stem cells in the developing brain by PRDM16

    Författare :Li He; Qi Dai; Christos Samakovlis; Simon Hippenmeyer; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brain development; Neural stem cell; PRDM16; BMP signaling; Choroid plexus; Cortical neurogenesis; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : The mammalian brain comprises a large number and diversity of neurons and non-neural cells. Most of these cell types derive from a single sheet of neuroepithelium (NE) that contains a limited pool of neural stem cells (NSCs).  NSCs in the developing brain are under complex regulation to achieve maximum daughter cell type diversity.

    Sammanfattning : Toxoplasma gondii is an obligate intracellular parasite that infects all warm-blooded vertebrates including one third of the global human population. While infection is typically asymptomatic in healthy human hosts, reactivated and acute infection in immunosuppressed or immunecompromised individuals can lead to lethal toxoplasmic encephalitis After ingestion, the parasite crosses the intestinal epithelium and rapidly achieves systemic dissemination, ultimately establishing chronic infection in the brain.

    Sammanfattning : Toxoplasma gondii is an obligate intracellular Apicomplexan parasite that could possibly infect all warm-blooded animals. Acute infections with T. LÄS MER

  5. 15. Biomarkers of ionising radiation relevant to carcinogenesis : Dose, dose rate and LET dependency of the responses

    Författare :Milagrosa López Riego; Andrzej Wojcik; Lovisa Lundholm; Alexandros G. Georgakilas; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ionising radiation; low dose; low dose rate; linear energy transfer LET ; mixed beams; dose and dose rate effectiveness factor DDREF ; cancer; DNA damage response; biomarkers; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : A better understanding of the relationship between ionising radiation (IR) dose, dose rate and radiation quality, and the risk of stochastic effects would improve risk extrapolation from atomic bomb survivors’ data. Owing to insufficient statistical power of epidemiological studies to detect excess incidence of cancer following low doses of IR delivered at low dose rates (LDLDR), as typically encountered in most common human exposure scenarios, radiobiological experiments are fundamental to describe the biological effectiveness of LDLDR and to define the underlying molecular mechanisms.
