Smokovitis, A. (author), Astrup, T. (author), Gaubius instituut TNO (author)Fibrinolytic activity (caused by a plasminogen activator) in the spinal cord was highest in the rat, lowest in the rabbit, and intermediate in the guinea pig. In all species the activity was highest in relation to the pia mater. The central spinal canal was active in the rat and the rabbit, but mostly inactive in the guinea pig. Foci of activity...article 1978

Tulleken, C.A.F. (author), van Dieren, A. (author), Mollevanger, W.J. (author), van Eijck, P. (author), Inst. Med. Phys., TNO, Utrecht, Netherlands (author)In a group of 21 cats, the middle cerebral artery pressure (MCAP) was recorded by means of a catheter introduced into the artery at its origin, just distal to the occlusion. The effects of hypertension, hypercapnia, and hypocapnia were studied. In a group of five cats, both middle cerebral arteries (MCA) were catheterized and the pressure was...article 1978

van der Schans, G.P. (author), Medisch Biologisch Laboratorium TNO (author)The induction of single- and double-strand breaks in DNA by γ-rays has been measured. The maximum number of nucleotide paris (a) between two independently induced single-strand breaks in opposite strands of the DNA which cannot prevent the occurrence of a double-strand break was found to amount to about 16. This value did not differ...article 1978

Tanger, H.J. (author), Vanwersch, R.A.P. (author), Wolthuis, O.L. (author), Medisch Biologisch Laboratorium TNO (author)A method is described whereby open field behaviour of rats can be automatically registered using a TV camera, a video converter, an X-Y recorder and a papertape puncher. Use is made of the scanning properties of the TV camera to obtain the X and Y coordinates of the rat's position and to print this position on an X-Y recorder to obtain the...article 1978

Schuffel, H. (author), Lazet, A. (author), Instituut voor Zintuigfysiologie TNO (author)This paper is a survey of a series of reports, sponsored by the Netherlands Ship Research Centre, the Royal Dutch Shipowners Organisations and the Netherlands Maritime Institute. It concerns ergonomics in bridge and wheelhouse design. The reports deal with bridge mock-up studies and an evaluation of bridge lay-out by means of simulation. It is...conference paper 1978

Graveland, A. (author), Bosveld, P. (author), Marseille, J.P. (author), Centraal Instituut voor Voedingsonderzoek TNO (author)A study was made of the conditions for determining all thiol (SH) groups and disulphide (S—S) bonds in wheat flour and dough. Thiol groups were determined by amperometric titration with Ag2SO4, the flour or dough which contains proteins and peptides being suspended in a solution of 6 m urea and 10−4 M sodium dodecyl sulphate (SDS). The potential...article 1978

Knook, D.L. (author), Instituut voor experimentele gerontologie TNO (author)Ageing is associated with declines in the functional capacities of several organs. General causes for the decline can be divided into: 1. intrinsic cellular causes and 2. extracellular causes, e.g., changes in blood circulation and distribution. For the first group of causes, there is evidence for a decrease in the numbers of long-lived cells in...article 1978

(author), Instituut voor experimentele gerontologie TNO (author)Rabbit corneal cells transformed by a putative human type-C helper virus pseudotype of the mouse sarcoma virus produce large amounts of transforming and non-transforming viruses. The virions are antigenically related to the woolly monkey (simian) sarcoma-leukemia type-C oncovirus. Typical sarcoma virus lesions developed in newborn rats injected...article 1978

Essentially, it describes the transmission of mammary tumor virus (MTV), genetics of susceptibility to exogenous MTV,...article 1978
