  1. 1. Vitamin A regulated neuronal regeneration and homeostasis

    Author : Sofia Håglin; Anna Berghard; Staffan Bohm; Leif Carlsson; Ola Hermanson; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Activity dependent; Adult stem cells; Ageing; CYP26B1; Homeostasis; Metaplasia; Neurogenesis; Olfactory epithelium; Regeneration; Respiratory epithelium; Retinoic acid; Sensory map; Vitamin A;

    Abstract : The olfactory epithelium is a dynamic tissue maintained by continuous neurogenesis throughout life. Upon injury, neurons and other olfactory cell types are regenerated through proliferation of horizontal stem cells. Some genes that regulate vitamin A metabolism are spatially expressed in the olfactory epithelium. READ MORE

  2. 2. Isoform-specific regulation of Drosophila gut immunity and regeneration by the POU/Oct transcription factor Nub/Pdm1

    Author : Xiongzhuo Tang; Ylva Engström; Tony Ip; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; POU; Nubbin; Drosophila; intestinal stem cell; epithelium regeneration; midgut; mitosis; Antimicrobial peptides; innate immunity; NF-κB; bacterial infection; transcriptional regulation; homeostasis; Molecular Biology; molekylärbiologi;

    Abstract : Innate immune reactions protect organisms against a variety of infections.  In metazoans, these reactions involve both cellular and humoral responses. The immune responses have to be well-tuned, as excessive immune activation is associated with tissue-specific pathologies. READ MORE

  3. 3. TGF-B signaling in Neuroblastoma and Renal Cell Carcinoma

    Author : Anna-Karin Boström; Institutionen för translationell medicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Renal Cell Carcinoma; ATN; Regeneration; Notch; TGF-B; EMT; Neuroblastoma; MYCN; miR-17-92;

    Abstract : The tubular cells of the adult kidney are normally mitotically quiescent, in stark contrast to the massive regenerative capacity of the injured renal epithelium. In Paper I we characterized a new cell population of progenitor cells using ALDH as a selection marker. READ MORE

  4. 4. Flexible fiberoptic bronchoscopy : studies on methods for the diagnosis of carcinoma of the lung, bronchial mucosal damage and haemodynamic effects

    Author : Rune Lundgren; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Flexible fiberoptic bronchoscopy; bronchial carcinoma; brush biopsy; respiratory mucosal damage; regeneration; mucociliary clearance; haemodynamic effects; hypoxemia;

    Abstract : The diagnostic accuracy attained with the use of transbronchial fine needle aspiration biopsy, aspiration of bronchial secretion, bronchial washing, brush biopsy and forceps biopsy via a flexible fiberoptic bronchoscope was compared in patients with carcinoma of the lung. In endoscopic visible tumours the sensitivity of forceps biopsy was higher than that of the other methods. READ MORE

  5. 5. Multifunctional biomimetic materials for corneal regeneration

    Author : Mohammad Mirazul Islam; Karolinska Institutet; Karolinska Institutet; []

    Abstract : The cornea is the outermost layer of the eye, which is responsible for transmitting 95% of the incident light to the retina for vision and provides 70% of the focusing power of the eye. Corneal disease is a primary cause of blindness worldwide. READ MORE
