The specific insertion of a divalent metal ion into tetrapyrrole macrocycles is catalyzed by a group of enzymes called chelatases. Distortion of the tetrapyrrole has been proposed to be an important component of the mechanism of metallation. We present the structures of two different inhibitor complexes: (1) N-methylmesoporphyrin (N-MeMP) with the His183Ala variant of Bacillus subtilis ferrochelat
Nitric oxide (NO) can modulate both tumor growth and antitumor immune responses. In order to elucidate the mechanism of curative therapeutic immunization with IFNgamma-producing glioma cells, we examined the expression of inducible nitric oxide synthase (iNOS) in tissue sections from immunized animals. There was a significantly enhanced iNOS expression both intratumorally and at the immunization s
The aim of this thesis is to explore what impacts the IDF’s Military Orders regarding water have on Palestinians in the West Bank, taking international humanitarian law (IHL) and International Convention on Civil and Political Rights (ICCPR) into consideration. Thus, to discover whether or not Israel’s actions are compatible with IHL and treats everyone equal before the law, as stated in ICCPR Art
Today wind power developers are exploring the possibilities of establishing wind turbines in forest areas, therefore improved sound prediction models for complex terrains are valuable. The Swedish model used today is only applicable for hard flat ground without any vegetation, and is not adjustable to any meteorological parameters except the wind speed. The companies DELTA, DONG Energy and EMD Int
Arctic tundra vegetation composition is expected to undergo rapid changes during the coming decades because of changes in climate. Higher air temperatures generally favor growth of deciduous shrubs, often at the cost of moss growth. Mosses are considered to be very important to critical tundra ecosystem processes involved in water and energy exchange, but very little empirical data are available.
Stimulation of rat adipocytes with insulin and isoproterenol results in serine phosphorylation and activation of the adipocyte cGMP-inhibited phosphodiesterase (cGI PDE), events believed to be important in the antilipolytic action of insulin (Degerman, E., Smith, C.J., Tornqvist, H., Vasta, V., Manganiello, V.C., and Belfrage, P. (1990) Proc. Natl. Acad. Sci. U.S.A. 87,533-537). Here we demonstrat
1. Knowledge about species habitat requirements is important when designing conservation strategies as well as for predicting species distributions. For herbivorous insects, insights in oviposition preferences can provide important information on their habitat requirements. 2. The oviposition preferences of Oberthür's Grizzled Skipper butterfly Pyrgus armoricanus Oberthür at its northern range bou
Quantum refinement (QR) is an approach in which the empirical restraints used in standard structural refinement to ensure that the details of the structure, e.g. bond lengths and angles, make chemical sense are replaced by more accurate quantum mechanical calculations for a small but interesting part of the structure. QR has previously been used for X-ray and neutron crystallography, cryogenic
Near surface geophysics applications are gaining more widespread use in geotechnical and engineering projects. The development of data acquisition, processing tools and interpretation methods have optimized survey time, reduced logistics costs and increase results reliability of seismic surveys during the last decades. However, the use of wide-scale geophysical methods under urban environments con
Göran Sonessonc Au-delà du langage de la danse – les significations du corps. Quelques considérations au sujet d’une sémiotique de la danse1 Sans être un expert en ce qui concerne la danse, et sans prétendre être parfaitement informé sur les tentatives antérieures de créer quelque chose comme une sémiotique de la danse (avec l’exception de Ikegami 1971 ; Hanna 1977 ; Shapiro 1981), je me propose d
