Patent number: 9315569Abstract: Methods of treating or delaying onset of a neurodegenerative disorder with ?-synuclein pathology in an individual comprise administering an antibody which is produced from a stabilized soluble ?-synuclein oligomer and capable of binding a stabilized soluble ?-synuclein oligomer, the stabilized soluble ?-synuclein oligomer having a lower formation rate to a non-soluble aggregated form than a non-stabilized soluble oligomer of the ?-synuclein. The antibody has been collected from a non-human animal to which stabilized soluble ?-synuclein oligomer had been administered or has been produced by hybridoma technology, phage display, ribosome display, mammalian cell display or bacterial display, and the disorder with ?-synuclein pathology is characterized by deposition of Lewy bodies and Lewy neurites or is selected from the group consisting of Parkinson's disease (PD), dementia with Lewy bodies (DLB), the Lewy body variant of Alzheimer's disease, and multiple system atrophy (MSA).Type: GrantFiled: July 21, 2014Date of Patent: April 19, 2016Assignee: BioArctic Neuroscience ABInventors: Lars Lannfelt, Joakim Bergström, Martin Ingelsson, Pär Gellerfors

Publication number: 20160037369Abstract: A radio base station transmits data symbols to a mobile terminal on multiple frequency carriers, e.g., in accordance with the MC-WCDMA or cdma2000 3x air interface protocols. The radio base station instructs the mobile terminal to report channel quality measurements obtained by the terminal for the multiple carriers over the same uplink channel during successive reporting intervals. According to one embodiment, the mobile terminal reports channel quality by receiving data symbols transmitted on a plurality of frequency carriers in a multi-carrier CDMA environment and measuring channel quality for the different frequency carriers. The mobile terminal reports individual ones of the channel quality measurements over the same uplink channel during successive reporting intervals.Type: ApplicationFiled: October 15, 2015Publication date: February 4, 2016Inventors: Stefan Parkvall, Erik Dahlman, Bo Göransson, Joakim Bergström

Publication number: 20150382284Abstract: A disclosed method is implemented by a network node in a wireless communication network to transmitting system information to a plurality of wireless terminals. The network node transmits a first group of system information blocks (SIBs) via a first physical channel, and transmits a second group of additional SIBs via a different, second physical channel. A corresponding network node operative to implement the method is also disclosed. Another disclosed method is implemented by a wireless terminal in a wireless communication network. The wireless terminal processes information received from a base station over a first physical channel to identify a first group of SIBs, and processes information received from the base station over a different, second physical channel to identify a second group of additional SIBs. A corresponding wireless terminal operative to implement the method is also disclosed.Type: ApplicationFiled: January 22, 2014Publication date: December 31, 2015Inventors: Sofia BRISMAR, Joakim BERGSTRÖM, Erik LARSSON, Fredrik OVESJÖ, Johan RUNE

Patent number: 9113453Abstract: An Uplink control channel resource Management Module (120, 130), referred to as “UMM”, and a method in the UMM for assigning, to a radio network node 110, uplink control channel resources, referred to as “UCCHR”, for use in a uplink control channel between the radio network node (110) and a communication device (160) are provided. The UMM obtains (210) resource allocation information, referred to as “RAI”, and generates (220) a resource allocation command, referred to as “RAC”, based on the RAI. The RAC indicates UCCHR to be used by the radio network node. Furthermore, the UMM provides (230) the RAC to the radio network node (110). Related methods and nodes to enable the UMM to assign UCCHR are also provided.Type: GrantFiled: April 30, 2010Date of Patent: August 18, 2015Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Peter Moberg, Joakim Bergström, Magnus Lindström, Gunnar Mildh
