Abstract: A track unit includes a belt track guided by guide wheels and support rollers. The belt track includes a core with drive lugs on the inner surface thereof, and ground-engaging lugs arranged in two parallel rows on the outer surface of the core. Each ground-engaging lug includes a load-bearing portion defined as a portion of the lug lying within a contact strip of the core, wherein the contact strips are lateral parts directly contacted by the guide wheels and/or support rollers when the belt track is moving. In one aspect, the ground-engaging lugs have uniform resilience and do not overlap or do not substantially overlap the central portion of the core between the contact strips. In another aspect, the ground-engaging lugs include a non load-bearing portion overlapping the central portion, wherein the non load-bearing portion is at least partially thinner or more resilient than the load-bearing portion.

Abstract: Caspases are cysteinyl aspartate-specific proteinases, many of which play a central role in apoptosis. This invention relates to the identification of a new murine caspase and its human homologue. The new molecules are most related to human/murine caspase-2 and human caspase-9 and possesses all the typical amino acid residues of the caspases involved in catalysis, including the QACRG box, and contains no or only a very short prodomain. Northern blot analysis revealed that mRNA expression of the new caspase is predominant in skin.
