Keyhole Suboccipital Endoscopic-Assisted Microsurgical Approach for Management of Pineal Region Tumors
2019
Patients' cosmetic satisfaction, pain, and functional outcomes after supraorbital craniotomy through an eyebrow incision
2014
Object The supraorbital approach through an eyebrow incision offers the opportunity to access a wide variety of lesions of the anterior, middle, and even the posterior fossa. The minimally invasive keyhole craniotomy limits brain exploration and retraction and offers the potential for improved surgical outcomes and reduced approach-related complications. Patient satisfaction, however, has not yet been reported in the literature. Methods From January 2002 through December 2011, the lead author (R.R.) used a supraorbital approach through an eyebrow incision for 418 patients with cerebral aneurysms, brain tumors or cystic lesions, and other miscellaneous pathological conditions. For 408 of th…
Endoscope-assisted keyhole surgery for aneurysms of the anterior circulation and the basilar apex
2000
In the treatment of cerebral aneurysms, preoperative surgical planning and intraoperative strategies for microsurgical approaches are important issues. Within the context of minimally invasive neurosurgery, so-called keyhole approaches, especially those with intraoperative endoscopic assistance, have gained increasing interest, but their application for cerebral aneurysm surgery is a matter of ongoing controversy. The main aspects of keyhole microsurgery, with and without endoscopic assistance, for cerebral aneurysms are explained. To present the keyhole concept, which is based on the preoperative analysis and intraoperative use of pre-existing anatomic windows, this article concentrates on…
LOW BACK PAIN IN YOUNG TEAM SPORT PLAYERS: A RETROSPECTIVE STUDY
2014
Background Low back pain (LBP) is a common complaint in general population affecting both genders and almost all age-groups. LBP is a common problem in sports as well, even in younger populations. LBP is prone to recur, thus there is a need for studies on the early phases of the problem in different sports. Objective To investigate the prevalence, nature, severity and risk factors of self-reported LBP in young team sport players. Design A retrospective cross-sectional study. Setting Finnish female and male basketball, floorball, ice hockey and volleyball teams. Participants This study is a part of an ongoing cohort study exploring risk factors for sports injuries. Players from 22 teams, a t…
Die Lungentuberkulose – aktuelle radiologische Diagnostik einer alten Krankheit
2000
Inzidenz. Abnehmende Inzidenzen aktiver Tuberkulose in den Industrielandern haben diese Erkrankung aus dem Bewusstsein vieler verdrangt. Dennoch stellt die Tuberkulose weiterhin weltweit die am haufigsten zum Tode fuhrende Infektionskrankheit dar. In den Industrielandern tragen Faktoren wie Einwanderungsbewegungen, zunehmende Verarmung und die Zunahme immunsupprimierter Patienten, insbesondere durch die HIV-Epidemie, dazu bei, dass ein Reservoir fur die Tuberkulose aufrecht erhalten wird. Diagnose. Eine fruhzeitige Diagnose ist wegen der spezifischen Therapiemoglichkeiten entscheidend fur den Krankheitsverlauf; im Falle von multiresistenten Stammen ist sie wichtig zur Verhinderung einer wei…
Haliotis tuberculata hemocyanin (HtH): analysis of oligomeric stability of HtH1 and HtH2, and comparison with keyhole limpet hemocyanin KLH1 and KLH2
2000
The multimeric/higher oligomeric states of the two isoforms of Haliotis tuberculata hemocyanin (HtH1 and HtH2) have been assessed by transmission electron microscopy (TEM) of negatively stained specimens, for comparison with previously published structural data from keyhole limpet hemocyanin (KLH1 and KLH2) [see Harris, J.R., Gebauer, W., Guderian, F.U., Markl, J., 1997a. Keyhole limpet hemocyanin (KLH), I: Reassociation from Immucothel followed by separation of KLH1 and KLH2. Micron, 28, 31-41; Harris, J.R., Gebauer, W., Söhngen, S.M., Nermut, M.V., Markl, J., 1997b.

Software/Hardware Issues in Modelling Insect Brain Architecture
2011
The concept of cognitive abilities is commonly associated to humans and animals like mammals, birds and others. Nevertheless, in the last years several research groups have intensified the studies on insects that posses a much simpler brain structure even if they are able to show interesting memory and learning capabilities. In this paper a survey on some key results obtained in a joint research activity among Engineers and Neurogeneticians is reported. They were focussed toward the design and implementation of a model of the insect brain inspired by the Drosophila melanogaster. Particular attention was paid to the main neural centers the Mushroom Bodies and the Central Complex. Moreover a …

Vocational Meaning Survey (VMS) -kyselyn rakenne- ja sisällön validiteetti suomalaisen työelämä- ja uraohjauksen näkökulmasta
2022
Tässä tutkimuksessa tarkastellaan uuden, Yhdysvalloissa kehitetyn Vocational Meaning Survey (VMS) -kyselyn soveltuvuutta työn merkitysten ja täyttymysten kokemusten kartoittamiseen osana ohjausprosessia suomalaiseen kyselyaineistoon (n = 218) perustuen. VMS-kysely sisältää neljä työn merkityksen ja täyttymyksen osa-aluetta: perustarpeet, itseen suuntautuminen, yhteisöön suuntautuminen ja itsensä ylittäminen. Konfirmatorisen faktorianalyysin tulokset osoittivat, että VMS-kyselyn neliulotteinen faktorirakenne vastasi odotettua ja osa-alueiden reliabiliteetit olivat hyvät, kun jäljelle jätettiin suomalaiseen aineistoon parhaiten soveltuvat väittämät. Tulokset tukevat VMS-kyselyn suomenkielisen…
Entre la ortodoxia y la revolución: Schumpeter y Keynes
2019
Tal vez, Joseph Alois Schumpeter y John Maynard Keynes fueron los economistas que mejor diagnosticaron la naturaleza de los nuevos cambios del capitalismo. ¿Cambios? ¿Qué cambios? ¿Cuándo? A finales del siglo XIX. En este texto se repasan sus principales contribuciones. En el contexto de la crisis, la profunda crisis de la modernidad más reciente. En este artículo se examina y se revisa su distinto compromiso, su compromiso con la realidad política. Sus propuestas fueron no solo un ataque contra la ortodoxia heredada, sino también una alternativa razonable y razonada a la revolución.
