  2. 1. Prediction of embryo viability by morphology and metabolomic profiling

    Author : Aisling Ahlström; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NIR spectroscopy; morphology; blastocyst; IVF; trophectoderm; live birth; metabolomic; embryo;

    Abstract : Abstract The ultimate challenge for all in vitro fertilisation (IVF) clinics is to develop the ability to select for transfer the best single embryo first, from the patient’s cohort of embryos, thereby maximising the chance of pregnancy while the incidence of multiple pregnancies is kept to a minimum and fewer transfer cycles are required. This ambition has driven extensive research and development into methods that can be used to predict embryo viability. READ MORE

  4. 2. Yolk sac morphology and uterine blood flow are associated with fetal outcome in diabetes pregnancy

    Author : Sheller Zabihi; Uppsala universitet; []
    Keywords : Diabetes; yolk sac; embryo; gene expression; blood flow; folic acid; SOD; apoptosis;

    Abstract : Women with pregestational diabetes have a 3-5 times increased risk of giving birth to malformed babies compared with non-diabetic women. The malformations are likely to be induced before the seventh week of pregnancy, when the yolk sac is partly responsible for the transfer of metabolites to the embryo, and the uterine blood flow to the implantation site determines the net amount of nutrients available to the conceptus.

  5. 3. From Parasitoids to Gall Inducers and Inquilines : Morphological Evolution in Cynipoid Wasps

    Author : Hege Vårdal; Fredrik Ronquist; Göran Sahlén; Ulf Jondelius; Nunzio Isidoro; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; gall inducer; parasitoid; inquiline; gall induction; morphology; Biologi; Biology; Biologi;

    Abstract : One of the large lineages of parasitic wasps, the Cynipoidea, exhibits three distinctly different life modes. Slightly more than half of the about 3000 species are parasitoids in insect larvae, whereas the remaining species are associated with plants, either as gall inducers or as inquilines (guests feeding on plant tissue in galls).

  6. 4. Fetal Outcome in Experimental Diabetic Pregnancy

    Author : Sheller Zabihi; Ulf Eriksson; Michael Welsh; Elisabeth (Lisa) Persson; Uppsala universitet; []
    Keywords : Cell biology; Rat; Mouse; TG; KO; Diabetes in Pregnancy; Embryo; Folic acid; Superoxide dismutase; Catalase; Glutathione peroxidase; Vascular endothelial growth factor-A; Folate binding protein-1; Bax; Bcl-2; Caspase-3; P53; Pax-3; Blood flow; Cellbiologi;

    Abstract : Women with pregestational diabetes have a 2-5 fold increased risk of giving birth to malformed babies compared with non-diabetic women. Diabetes-induced oxidative stress in maternal and embryonic tissues has been implicated in the teratogenic process. READ MORE

  7. 5. Mechanisms controlling striatal projection neurone generation, from patterning to early differentiation

    Author : Håkan Toresson; Klinisk minnesforskning; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pbx; meis; sonic hedgehog; small eye; pax6; gsh2; gsh1; cerebral cortex; striatum; telencephalon; mutant; development; mouse; embryo; retinoic acid; Clinical biology; Klinisk biologi;

    Abstract : The striatum is part of the telencephalon, the most anterior part of the vertebrate brain. From when it first can be identified, telencephalic morphology is highly complex and a wide range of mechanisms has been suggested to participate in its induction, patterning and neurogenesis.
