Title: Predicting immunogenicity of t cell epitopes
Inventor: SAHIN UGUR
IPC: A61K39/00
Filed: 2014-05-07
Abstract: The present invention relates to methods for predicting T cell epitopes. In particular, the present invention relates to methods for predicting whether modifications in peptides or polypeptides such as tumor-associated neoantigens are immunogenic or not. The methods of the invention are useful, in particular, for the provision of vaccines which are specific for a patient’s tumor and thus, in the context of personalized cancer vaccines. In a particular embodiment the invention is a method of making a vaccine by predicting immunogenicity of modified peptides using three scores/criteria related to the (1) binding of non-modified peptides to MHC molecules (Mwt) (2) binding of modified peptides to MHC molecules (Mmut) and (3) a T score based on the chemical and physical similarities between the non-modified and modified amino acids as an indicator for TCR binding.

Patent NZ-723398-A (NZ)
Title: A roof
Inventor: RYAN BRAD
IPC: E04D3/30
Filed: 2015-02-18
Abstract: A roof for a building includes a roof frame having a plurality of spaced-apart roof trusses (17) extending between a ridge and a gutter (7) of the roof and a plurality of horizontally-extending roof cladding sheets (9) fixed directly from a structural viewpoint to the trusses so that there is a direct structural connection between the roof cladding sheets and the roof frame. Water flows horizontally along the roof cladding sheets and discharges from the ends thereof. Weatherproofing is provided in the form of an under flashing sheet on any one of a hip, valley, or barge board section of the roof that is also secured directly to the roof frame. The under flashing sheet is positioned so that ends of the roof cladding sheets that extend to the hip, valley or barge board section at least partially overlie the under flashing sheet. The under flashing sheet includes an elongate channel or a plurality of elongate channels extending along the sheet that receive water that discharges from the ends of the roof cladding sheets. The channel or channels direct the water downward from the roof so that the water does not flow into a roof space between the building and the roof. There are no structural elements between the roof cladding sheets and the trusses. The roof frame does not include, and does not need, horizontally extending battens on which the roof cladding sheets are secured, that are often required for typical roof construction. Securing structural metal roof cladding sheets directly to roof trusses provides an opportunity to significantly reduce installation cost and construction time.

Title: Automatic opening device for carton packages
Inventor: COSTA IVAN FERREIRA DA
IPC: B65D51/22
Filed: 2014-11-24
Abstract: The caps of the known opening devices for carton packages, when unscrewed upwardly the first time, have to drive a cutting element which must make a downward movement, thereby making necessary the cap to be provided with heavy elongated cam followers to drive the cutting element. The inventive automatic opening device obviates the use of cam followers by providing a spout (3) with an external thread (2) comprising a first groove (2c) and a second groove (2f) of opposite orientations and connected each other, and a cap (26) having internal screw thread segments (19) which engage said first groove (2c) and second groove (2f), the cap (26) being integral with at least one protruding cutting element (30), thereby making it lighter than the automatic opening device for carton package known in the art. When the cap (26) is unscrewed the first time from the spout (3) it makes first a downward movement, thereby enabling the protruding cutting element (30) to cut the aluminium layer of the carton package.
