Abstract For over a decade the nation‐states of the world have been redefining the legal and political status of the world's oceans, both unilaterally and in multilateral negotiations. Despite the growing importance of ocean policy, we know too little concerning what are current nation‐state marine interests, how they make their marine related decisions, or how they organize themselves for marine policy. This paper was written as an organizing paper for a workshop to assess the state of the art in national ocean policy studies. It was sponsored by the Marine Science Affairs Program, International Decade of Ocean Exploration Office, National Science Foundation. The paper states the goal of the workshop, it defines the terms of reference, such as public policy, public policy analysis, comparative public policy analysis and national ocean policy; it offers a “systems”; influenced model for the evaluation of national ocean policy, and it identifies the state of our knowledge of the various components of national ocean policy by performing a computer‐based survey of the literature. Some 5,000 studies were examined and reduced to 1,000 relevant items. Highlights of the findings show that: 1) we know most about the output stage of ocean policy, less about input, little about process; 2) we know most about bureaucratic ocean decisions, less about legislative, little about judicial ocean decisions; 3) output studies rose and declined, input studies have increased steadily, and process studies may show a sharp rise; 4) we know most about the United States, Japan, and the USSR, less about Western Europe, little about the Third World; and 5) most of the studies were conducted by those using “traditional”; research tools. 相似文献

Summary We examined the morphological expression of dystrophin in the intrafusal muscle fibers in skeletal muscle from normal human and Duchenne muscular dystrophy (DMD) patients, using antisera against the N-terminal and C-terminal regions of dystrophin. The intrafusal fibers of normal muscle express dystrophin on their cell surface membrane, but those of DMD muscle do not.Abbreviation DMD

Fifty-one patients with autoimmune hepatitis have been studied for HLA association by conventional serology and also by modified polymerase chain reaction-restriction fragment lenght polymorphism (PCR-RFLP) genotyping.HLA-DR4 was significantly associated with autoimmmune hepatitis (46 of 51 patients, 90.2%). DNA typing of the DRB1 gene for 43 DR4-positive patients by using the PCR-RFLP technique revealed that of 43 patients, 33 had DRB1
*
0405 (Dw15), five had DRB1
*
0406 (DwKT2), four had DRB1
*
0403 (Dw13a), two had DRB1
*
0401 (Dw4), two of 43 had DRB1
*
0407 (Dw13b) and one had DRB1

0408 (Dw14b). Thus, there was no significant difference in Dw frequencies between DR4-positive patients and DR4-positive healthy subjects. These findings suggest that the DR4-specific sequence (Val 11 and His 13 at amino acid positions 11 and 13, respectively), but not particular Dw-associated DR4 sequence, in the first domain of the DRB1 chain contributes to susceptibility to autoimmune hepatitis among Japanese. Interestingly, all five of the DR4-negative patients had the DR2 specificity (DRB1
1502 or 1601). Taken together, these results imply that the basic amino acids at position 13, which is present only on the DR2 and DR4 B1 molecules (Arg on DR2 and His on DR4), are most important for determining the predisposition to autoimmune hepatitis.

The chromosomal location of the rat interferon-alpha (IFNA) gene cluster was determined by fluorescence in situ hybridization. The fluorescent signals were localized to 5q31----q33. A previous report, using somatic cell hybrids, had suggested that the IFNA locus maps at a different region on rat chromosome 5. 相似文献

We examined the effects of a limitation of the O2-supply onthe syntheses of bacteriochlorophyll ap and carotenoids in isolatesof aerobic marine bacteria, OCh 101 and OCh 114, grown heterotrophically.Whereas they formed these pigments fairly well under high aerationin the dark, a limitation of the O2-supply resulted in the decreasedsyntheses of bacteriochlorophyll in both strains. Synthesesof carotenoids also were depressed under low aeration but toa lesser extent (especially in OCh 101) than the depressionof bacteriochlorophyll synthesis. Aerobic incubation of a cultureof OCh 101, that previously had been grown semiaerobically,induced the supplementary synthesis of bacteriochlorophyll.This induction was inhibited almost completely by chloram-phenicol.The absorption spectra of suspensions and solvent extracts ofcells grown aerobically or semiaerobically are reported.

1992. Application of a simple culture of Plasmodium berghei for assessment of antiparasitic activity. International Journal for Parasitology 22: 1137–1142. Mouse erythrocytes infected with Plasmodium berghei were incubated for a short period in microplate wells. The parasites changed morphologically from the immature ring form to mature schizonts, and free merozoites were released. However, reinvasion of the erythrocytes appeared not to be possible in this system. This intraerythrocytic one-step growth of the parasite could be determined quantitatively by counting incorporation of 'H-hypoxanthine. The incorporation was markedly decreased by addition of certain antiparasitic agents to the culture. The sensitivity of this growth inhibition test was comparable to or higher than the mouse protection test. The results suggested the practical utility of this simple assay in screening antimalarial activity. 相似文献

Summary In Rana catesbiana (10 adults) and Rana nigromaculata (2 adults), a number of mast cells are found within the lymphatics of the tongue. The round mast cells cluster in a monocellular layer in certain parts of the lymphatic walls and are either in close adhesion to the endothelial cells, or in contact with them with a slender cytoplasmic process.Microscopic examination of the lymph taken from the sublingual lymph sac reveals that the mast cells on the lymphatic wall can become free to move into the lymph only by vigorous massage of the tongue. Otherwise the lymph contains only a few free mast cells.The origin of the mast cells in this peculiar, supra-endothelial position is discussed. A figure that might suggest the migration of mast cells from the connective tissue into the lymphatics was encountered only rarely.This work is dedicated to Dr. Berta Scharrer on her 60th birthday. 相似文献

Soil moisture variability on a steep slope near a ridge in a forested mountain range, Shikoku, Japan: a model study 总被引:1,自引:0,他引:1

Variability in soil moisture on a steep slope near a ridge in a forested mountain range, Shikoku, Japan, was studied observationally and numerically. Vertically integrated soil moisture, from a depth of ?60 cm to the surface, W, was introduced as a key indicator, and its seasonal variation was analysed on a daily basis from August 2011 to August 2012. The “bucket with a bottom hole” (BBH) model of Teshima et al. (2006) was improved to consider the forest environment in simulating the variation in W. A “big-leaf” model was incorporated into the modified BBH model to estimate transpiration and interception by trees. The simulated soil moisture agreed reasonably with observed values on a daily to inter-seasonal timescale. 相似文献

The effect of muramyldipeptide (MDP), N-acetylmuramyl-l-alanyl-d-isoglutamine [MDP(Ala)], and its analogs on bacterial infection was studied using the experimental model of sepsis infection in mice. Injection of MDP(Ala) gave mice definitive protection against E. coli infection, but only partial protection against P. aeruginosa or K. pneumoniae infection. Several factors influencing the protective activity of MDP (Ala) on E. coli infection were studied, and it was demonstrated that the activity was induced by various routes of administration of MDP(Ala), including the oral route, and was markedly influenced by the bacterial inoculum size. It was also shown that the effective dose of MDP(Ala) was 100 μg per mouse for intraperitoneal, intravenous or subcutaneous injections and 1,000 μg per mouse when administered orally. Furthermore, the optimal interval between MDP-treatment and infection was 24 hr when the treatment was carried out before infection. Clearance of bacterial cells in blood was observed after E. coli infection in mice treated with MDP(Ala). The efficacy of MDP(Ala) and two analogs, N-acetylmuramyl-l-valyl-d-isoglutamine [MDP(Val)] and N-acetylmuramyl-l-seryl-d-isoglutamine [MDP (Ser)], was evaluated for the E. coli infection; MDP(Val) was proven to be slightly less active than MDP(Ala), and MDP(Ser) to be the least effective, although MDP(Val) or MDP(Ser) was reported to have higher adjuvanticity than MDP (Ala) for the development of delayed-type hypersensitivity. 相似文献
