2. 11. Interactions between neural retina, retinal epithelium and choroid

   Author : Lena Ivert; Karolinska Institutet; Karolinska Institutet; []
   Keywords : RPE; neural retina; basal lamina; Bruch s membrane; choroid; subretinal space; bleb detachment; ICG; FAG; SLO; choroidal blood flow.;

   Abstract : The retinal pigment epithelium (RPE) is a non-replicating monolayer that plays a key role nursing the photoreceptors of the neural retina, regulating fluid movement within the subretinal space, maintaining a basal laminar layer of Bruch s membrane, and influencing the choriocapillaris. This project investigates how surgical manipulation of the retinal epithelial layer influences the neural retina, the choroid and the epithelial layer itself. READ MORE

4. 12. Morphology and biochemistry of the tympanic membrane in relation to retraction pathology

   Author : Johan Knutsson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Tympanic membrane; retraction pathology; secretory otitis media; cholesteatoma; pars tensa; lamina propria; keratinizing epithelium; collagen type; progenitor cells; stem cells; immunohistochemistry; electron microscopy;

   Abstract : Otitis media is very common during childhood and may predispose for tympanic membrane (TM) pathology later in life. Therefore, it is important to investigate the possible changes in TMs subjected to otitis media. There is evidence of a relationship between previous otitis media and TM retraction disease.

5. 13. On the cholinergic c-bouton

   Author : Johan Hellström; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Acetylcholine; Brainstem; Immunohistochemistry; In situ hybridization; Motoneurons; Muscarinic receptors; Rat; Spinal cord; Ventral horn cells;

   Abstract : The cholinergic C-bouton is a large nerve terminal type exclusively contacting motoneuron cell somata and proximal dendrites. C-boutons are characterized by subsurface cisterns found beneath the postsynaptic membrane, which is an exclusive feature for these nerve terminals. The origin of the C-boutons is unknown. READ MORE

6. 14. Physically Based Engineering Models for NCF Composites

   Author : Fredrik Edgren; Dan Zenkert; Michael WIsnom; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction engineering; Konstruktionsteknik;

   Abstract : Non-Crimp Fabrics - NCF – are increasingly being used as reinforcements in high performance composite materials. NCF offer the manufacturing advantages from textile preforms in combination with excellent mechanical performance. This study concerns the mechanical performance of NCF composites. READ MORE

7. 15. Synaptic organization of nociceptive relay nuclei in the cat and primate thalamus

   Author : Ann-Charlott Ericson; Per Brodal; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : The fine structure of two thalamic nociceptive relay nuclei, the nucleus submedius (Sm) in the cat, and the posterior region in the owl monkey, was investigated using anatomical tract tracing techniques, immunohistochemical staining for neuroactive substances, and threedimensional reconstructions of synaptic circuitry. Ascending lamina I axons, labeled by anterograde transport of Phaseolus vulgaris leucoagglutinin, gave rise to two different types of termination in Sm: large, compact clusters of numerous boutons were predominant in the dense focus of the terminal field after a tracer injection at the site of nociceptive-specific neurons in lamina I, and boutons-of-passage type terminations were conspicuous in the periphery of a lamina I terminal field in Sm and predominant following a tracer injection at the site of thermoreceptive-specific neurons in lamina I.
