PURPOSE: To describe the clinical, spectral-domain optical coherence tomography and electrophysiological features of C1QTNF5-associated late-onset retinal degeneration in a molecularly confirmed pedigree. METHODS: Five members of a family participated, and affected individuals (n = 4) underwent detailed ophthalmologic evaluation including fundus autofluorescence and spectral-domain optical coherence tomography imaging and electroretinography. Electrooculography was performed in three individuals. RESULTS: The visual acuity was initially normal and worsened with time. Anterior segment abnormalities included peripupillary iris atrophy and long anterior insertion of zonules. Peripapillary atrophy, drusenoid deposition, and scalloped sectorial chorioretinal atrophy were observed in all older individuals (n = 3). Fundus autofluorescence demonstrated hypofluorescent areas corresponding to regions of chorioretinal atrophy. The spectral-domain optical coherence tomography demonstrated multiple areas of retinal pigment epithelium-Bruch membrane separation with intervening homogeneous deposition that corresponded to the drusenoid lesions and areas of chorioretinal atrophy. Electrooculography was normal in one individual and showed abnormally low dark trough measures in older individuals (n = 2). Electroretinography was normal in early stages (n = 1), but showed marked abnormalities in the rod system (n = 3), which was predominantly inner retinal (n = 2) in late stages. CONCLUSION: Late-onset retinal degeneration is a progressive degeneration, and anterior segment abnormalities present early. The widespread sub-retinal pigment epithelium deposition seen on spectral-domain optical coherence tomography in older individuals appears to be a characteristic in late stages. Electrooculography demonstrates abnormalities only in late stages of the disease.

Maternal care in Gargaphia decoris is described for the first time. A video is presented as supplementary material. The knowledge on such trait within Tingidae is summarized. The behavior within the family is discussed, and the potential as a source of phylogenetic characters for further analyses is stressed.

v-E10, a caspase recruitment domain (CARD)-containing gene product of equine herpesvirus 2, is the viral homologue of the bcl-10 protein whose gene was found to be translocated in mucosa-associated lymphoid tissue (MALT) lymphomas. v-E10 efficiently activates the c-jun NH(2)-terminal kinase (JNK), p38 stress kinase, and the nuclear factor (NF)-kappaB transcriptional pathway and interacts with its cellular homologue, bcl-10, via a CARD-mediated interaction. Here we demonstrate that v-E10 contains a COOH-terminal geranylgeranylation consensus site which is responsible for its plasma membrane localization. Expression of v-E10 induces hyperphosphorylation and redistribution of bcl-10 from the cytoplasm to the plasma membrane, a process which is dependent on the intactness of the v-E10 CARD motif. Both membrane localization and a functional CARD motif are important for v-E10-mediated NF-kappaB induction, but not for JNK activation, which instead requires a functional v-E10 binding site for tumor necrosis factor receptor-associated factor (TRAF)6. Moreover, v-E10-induced NF-kappaB activation is inhibited by a dominant negative version of the bcl-10 binding protein TRAF1, suggesting that v-E10-induced membrane recruitment of cellular bcl-10 induces constitutive TRAF-mediated NF-kappaB activation.

Mutants were produced in the A-domain of HbpR, a protein belonging to the XylR family of σ(54)-dependent transcription activators, with the purpose of changing its effector recognition specificity from 2-hydroxybiphenyl (2-HBP, the cognate effector) to 2-chlorobiphenyl (2-CBP). Mutations were introduced in the hbpR gene part for the A-domain via error-prone polymerase chain reaction, and assembled on a gene circuitry plasmid in Escherichia coli, permitting HbpR-dependent induction of the enhanced green fluorescent protein (egfp). Cells with mutant HbpR proteins responsive to 2-CBP were enriched and separated in a flow cytometry-assisted cell-sorting procedure. Some 70 mutants were isolated and the A-domain mutations mapped. One of these had acquired true 2-CBP recognition but reacted hypersensitively to 2-HBP (20-fold more than the wild type), whereas others had reduced sensitivity to 2-HBP but a gain of 2-CBP recognition. Sequencing showed that most mutants carried double or triple mutations in the A-domain gene part, and were not located in previously recognized conserved residues within the XylR family members. Further selection from a new mutant pool prepared of the hypersensitive mutant did not result in increased 2-CBP or reduced 2-HBP recognition. Our data thus demonstrate that a one-step in vitro 'evolutionary' adaptation of the HbpR protein can result in both enhancement and reduction of the native effector recognition.

Opinnäytetyömme on kaksiosainen, ja se on osa lapsiperheiden terveyden edistämisen projektia, jossa Helsingin ammattikorkeakoulu Stadia on osallisena. Ensimmäisen työn aiheena oli Haagan terveysasemalla järjestettävä teemapäivä, jonka kohderyhmänä olivat lastenneuvolassa asioivat vanhemmat sekä neuvolan terveydenhoitajat. Tarkoituksena oli lisätä vanhempien tietoa alle 3-vuotiaan lapsen ravitsemuksesta ja sen vaikutuksesta tuki- ja liikuntaelimistön kehitykselle. Opinnäytetyömme toinen osa perustuu ensimmäisen työn pohjalta nousseeseen tarpeeseen tehdä terveydenhoitajille konkreettinen apuväline vanhemmille suunnattuun ravitsemusohjaukseen. Työn tarkoituksena on välittää tietoa lapsiperheiden ruokailutottumuksista pienten lasten vanhemmille. Suunnittelemme ja toteutamme vanhemmille suunnatun opaslehtisen, jotta heillä olisi helposti käytettävissään olevaa tietoa lasten ravitsemuksesta ja vinkkejä arkipäivän ruokailutilanteisiin. Opaslehtisen sisältö pohjautuu osittain ensimmäisen opinnäytetyön teoriaosuuteen, jossa käsiteltiin lapsen terveellistä kehitystä tukevaa ravitsemusta, perheiden ruokailutottumuksia sekä ravitsemukseen liittyviä uhkatekijöitä. Sisällön suunnittelussa käytimme lisäksi apuna uusinta tutkimustietoa lapsen ravitsemuksesta sekä terveysaineistolle laadittuja laatukriteereitä hyvän lopputuloksen varmistamiseksi. Halusimme tuottaa helposti lähestyttävän ja selkokielisen käytännön oppaan jokapäiväiseen käyttöön. Sisältöaiheiksi valitsimme lasten ravitsemukseen liittyviä keskeisiä asioita: alle 3-vuotiaan lapsen ravitsemus, perheen ruokailutottumukset, ruokareseptejä ja vinkkejä päivittäiseen ruoanvalmistukseen. Opaslehtisen nimenä on ”Pieni ruokakirja - Opaslehtinen pienten lasten vanhemmille”. Opaslehtinen soveltuu terveysasemien käyttöön ja siitä on todellista hyötyä monille lapsiperheille sekä terveydenhoitajille työssään.
