Immunohistochemical study of rats receiving peripheral immunization with IFNg transfected glioma cells

Popular Abstract in Swedish Vi har studerat hur man kan använda immunsystemet för att behandla råttor med hjärntumör (maligna gliom). Eftersom råttor väldigt sällan utvecklar hjärntumörer, så måste vi injicera tumörceller i hjärnan själva. Om djuren inte får någon behandling dör de vanligen inom ca. 24 dagar. Får de däremot en injektion i buken eller under huden på benet med genmanipulerade tumörcMalignant glioma is, with rare exceptions in younger adults, an uncurable brain tumor, as very few survive more than 1-2 years after diagnosis. Despite advances in recent years, current treatments such as surgery, radiotherapy and chemotherapy only prolongs the life of the patients. Because of the poor prognosis, several additional therapies have been investigated and are under development, such a

Aspects on the Regio and Stereo Selectivity in the Hydrolsilylation of 1,3-Dienes

Popular Abstract in Swedish Hydrosilyleringsreaktionen är formellt en addition av en hydrosilan till ett omättat system. Reaktionen är oftast katalyserad av en övergångsmetall, och i denna process är det möjligt att påverka på vilket sätt additionen sker. Denna avhandling är en sammanfattning av fyra artiklar som behandlar regio-, stereo- och kemoselektivitet vid addition av hydrosilaner till konjThis thesis is a summary of four papers concerning various aspects on the transition metal catalysed hydrosilylation of 1,3-dienes. The hydrosilylation reaction is formally an addition of a hydrosilane to an unsaturated system and depending on the reaction conditions, control of stereo-, regio-, and chemo-selectivity can be achieved. Optically active heterobidentate P,N ligands were synthesised f

The Effect of Visual Gender on Abuse in Conversation with ECAs

Previous studies have shown that female ECAs are more likely to be abused than male agents, which may cement gender stereotypes. In the study reported in this paper a visually androgynous ECA in the form of a teachable agent in an educational math game was compared with a female and male agent. The re-sults confirm that female agents are more prone to be verbally abused than male agents, but also

Acute improvement of contralateral hand function after deafferentation

To study cortical re-organisation after acute hand deafferentation, we investigated 10 experimental subjects and 10 controls for function in the left hand, before, during and after tourniquet induced anaesthesia of the right hand. fMRI was performed in three experimental subjects. Tourniquet-induced right hand anaesthesia resulted in rapid significant improvement in grip strength, tactile discrimi

Personal Value

Certain things, like justice, have impersonal value, other things, like your children, carry personal values: they have value for you. Besides whatever value, period, they have, they are valuable to you. The philosophical as well as non-philosophical literature is inundated with suggestions about the kinds of thing that are good-for us or, if it is a negative personal value, what is bad-for us. Fo

A 30 GHz 90-nm CMOS Passive Subharmonic Mixer with 15 GHz Differential LO

A new passive subharmonic mixer topology is presented and compared to a previously published passive topology. The comparison is conducted using simulations at 30 GHz with a 90-nm CMOS design kit. The advantage of the new passive subharmonic mixer is that it only requires a differential local oscillator (LO) signal, compared to the previously published mixer that requires a quadrature LO signal.
