Sphingolipids make up only a small portion of membrane phospholipids and yet are structurally diverse and essential. This suggests that sphingolipids may be involved in biological regulation or signal transduction rather than as structural components of the plasma membrane. Biological phenomena involving sphingolipids or metabolites, such as ceramide, sphingosine, and sphingosine 1-phosphate, are numerous and include apoptosis, cell cycle regulation, cellular senescence, differentiation, calcium homeostasis, and tumor progression 130 ; . As an example, extracellular stimuli such as Fas, tumor necrosis factor alpha, ionizing radiation, and chemotherapeutic agents activate sphingomyelinase, which hydrolyzes sphingomyelin to ceramide and phosphocholine. Ceramide induces pleiotropic biological responses, including apoptosis, which could be clinically useful in cancer treatment strategies 130, 248 ; . The proapoptotic function of ceramide was suggested to be counteracted by antiapoptotic function of sphingosine 1-phosphate, a further metabolite of ceramide 61, 307 ; . S. cerevisiae has been the target of extensive studies of sphingolipid metabolism and signal transduction 73 ; . In cerevisiae, heat stress activates serine palmitoyltransferase, a key sphingolipid biosynthetic enzyme, leading to a marked increase in sphingoid bases including dihydrosphingosine and phytosphingosine 74, 155 ; . Recently, it was shown that the serine palmitoyltransferase is also activated by diverse stresses including nutrient starvation and DNA damage, resulting in increased levels of phytosphingosine 56 ; . This, in turn, leads to the degradation of nutrient permeases necessary for growth 56 ; . Serine palmitoyltransferase is the enzyme catalyzing the committed step in sphingolipid biosynthesis Fig. 9 ; . In cerevisiae, serine palmitoyltransferase is composed of the LCB1 and the LCB2 gene products 37, 237 ; . Inhibitors of this enzyme block the production of all sphingolipids, which, because these are essential lipids, is lethal. Many inhibitors of this pathway, including myriosin 223 ; , sphingofungins 361 ; , lipoxamycins 210, 334 ; , viridiofungins 212 ; , and cycloserine 337 ; , have been reported. Except for cycloserine, all of these are natural compounds and show very potent antifungal activity in the nano- to picomolar concentration range. However, since the serine palmitoyltransferase is conserved in both function and amino acid sequence from fungi to humans, these agents also inhibit the mammalian enzyme to various degrees. Dihydrosphingosine desaturase converts dihydrosphingosine to dihydroceramide in humans and dihydrosphingosine to phytosphingosine in fungi Fig. 9 ; . In cerevisiae, this enzyme is encoded by the SYR2 gene 120, 126 ; , and a mutation in this gene renders yeast resistant to syringomycin, a cyclic lipodepsipeptide produced by Pseudomonas syringae pv. syringae 57, 306 ; . At present, it is not known if syringomycin has specific inhibitory effects on the fungal enzyme compared to the mammalian enzyme. Ceramide synthase acylates dihydrosphingosine and phytosphingosine to produce dihydroceramide and phytoceramide, respectively Fig. 9 ; . Fumonisin B1 and australifungins inhibit this enzyme activity. Fumonisin B1 was shown to be active against both fungal and mammalian enzymes 223, 224 ; , but it has relatively low cytotoxicity against S. cerevisiae 350 ; . Australifungin is isolated from the fermentation extracts of Sporomiella australis and shows antifungal activity against Candida spp., Cryptococcus neoformans, and Aspergillus spp. 211 it has not yet been determined if australifungin also inhibits the mammalian enzyme. IPC synthase catalyzes the addition of inositol phosphate to phytoceramide, which is the first fungus-specific step in sphingolipid biosynthesis 238 ; . Therefore, this enzyme is an ideal.

My favorite winter tradition is the annual building of Frosty. Every year, I try to build a snowman bigger than the one from the year before. In an unfortunate turn of events, last year 's snowman, Frosty III, was almost knocked over during a snowstorm, forcing him permanently into a position that seemed to be from the Matrix. When he was first built, however, Frosty III was at least seven feet tall. This year, I'm hoping to make Frosty IV about nine feet tall. If the tradition continues, Frosty IX is going to require heavy construction equipment.
SUMMARY 1. Data are presented on 397 cases of tuberculosis treated with cycloserine CS ; alone, or in combination with INH. The original purpose of combining CS and INTl was to obtain a CS dose which would enhance the antituberculosis effects of INH, while keeping the toxicity at a minimum, 2. Our data show that the therapeutic efficacy of CS, alone or combined with INTl. depends upon the attainment and maintenance of CS plasma levels above 20 mcg. ml. 3. The toxicity of CS has been reduced, a ; by the concomitant administration of pyridoxine hydrochloride, which also protects against INH in combination therapy; b ; by spreading the daily dose as widely as possible, and C ; by insuring that the plasma levels of CS are kept well below 50 mcg. ml. Under this regimen, very few cases had to be discontinued because of toxicity. 4. Cycloserine alone in doses which maintain the plasma level at about 30 mcg. ml. has been shown to induce prompt clinical and roentgenographic improvement, a gain in weight, and rapid reversal of infectiousness, in a large proportion of both resistant and virgin cases of tuberculosis. 5. Bacillary resistance to CS developed but rarely, and in our experience has never been complete, even after continuous administration over several years. ACKNOWLEDGMENT: Lilly and Company tained through Eli as Lilly. The Seromycin, cycloserine The used CS-INH for this combination study was capsules supplied were by Eli also ob and cytarabine.

The field of knowledge management may be a key approach to doing this, she notes. This would provide greater access to real-time information by analysts, a greater use of matrix management, and the strategic rotation of employees. Knowledge management-- how organizations "create and use knowledge as part and parcel of their organizational culture"--stresses the importance of combining both the implicit knowledge of individual analysts highly personalized experience and wisdom ; with the explicit knowledge developed within their organizations. In his report for the Center, Robert Agranoff explains that operating in networks changes the nature of government organizations and requires executives with different managerial skills than in the past. In a network, a government manager serves as a convenor and becomes a participant, not a leader. In some cases, the government partner in a network may play a mediation role. Resources are more dispersed and cannot be controlled centrally, with program implementation occurring through the partners involved in pooling knowledge and technologies--not through government-owned and -operated programs. Agranoff also observes that government is not a bystander in a network. It possesses the legitimacy to deal with public problems and policy solutions, retains the authority to set rules and norms, contributes resources, and retains and shares knowledge. As a result, important networks cannot be sustained without a governmental role. In their report for the Center, William Snyder and Xavier de Souza Briggs describe a new tool for public managers called "communities of practice." This particular type of network features peer-to-peer collaborative activities that build members' skills. Used successfully in the private sector in large companies, communities of practice are "social learning systems" where practitioners informally "connect to solve problems, share ideas, set standards, build tools, and develop relationships with peers and stakeholders." As informal networks, these communities complement an organization's formal units by reaching across organizational boundaries. Because they are inherently boundary-crossing entities, they are particularly suited to large organizations and federal systems. In his report for the Center, John Scanlon tells the story of how the career leadership within the federal Bureau of Primary Health part of the Department of Health and Human Services ; used a collaborative approach to move beyond the traditional federal agency and program goals. Their mission was to pursue a "national goal" of providing 00 percent of community residents access to quality healthcare and eliminating health-status disparities between uninsured and insured populations. Because of their professional commitment to improving public health, staff at the Bureau of Primary Health created a self-organized group with a common vision and an impossible goal. Nevertheless, in a three-year period, they created a self-sustaining movement of multiple partnerships with leaders at the national, state, and local levels committed to a common vision with measurable goals. In his report for the Center, Donald Moynihan describes a successful federal, state, and local battle against an outbreak of Exotic Newcastle Disease, which is lethal to chickens but not humans. He describes how these agencies at all levels came together to deal with an infrequent event--it was the first outbreak in 30 years. To do this, they used an approach first piloted in the 970s by the Forest Service to fight forest fires, the Incident Command System ICS ; , which allows agencies to create a resilient network. In summing up the lessons from this effort, Moynihan notes that success depended upon the existence of a network of relationships that had been developed long before the outbreak. In fact, the way the and cytomel.

Children's lives. The changes contained in schedule 3 are aimed at achieving just that. Schedule 4 ensures that separating and divorcing parents have access to counselling and dispute resolution services. This further supports the government's policy of ensuring the availability of services that assist parents to resolve their disputes in an amicable fashion. Schedules 5 and 6 implement recommendations of the Family Law Council to clarify the role of independent children's lawyers as best interest advocates and to make the relationship between parenting orders and family violence orders clearer and easier to understand. Schedule 8 removes the terms `residence' and `contact' and replaces them with the term `parenting orders', which emphasises the need to make the system more family focused. More than one million Australian children have a parent living elsewhere. Even sadder than that is the fact that one in four never sees one parent or only sees them once a year. We cannot simply blame this sad statistic on the stereotype of the mum and dad who do not care about their parental role, which we so often hear about. With a number that large, you have to recognise that the longstanding failures in the system are contributing to the heartache; it is not just the stereotyping. This is a difficult problem. Any legislative arrangement which seeks to regulate the breakdown of a relationship will be a challenging one to reform, but this government does not shy away from the difficult problems, and it has done and will continue to do all that it can to assist families, especially children, in what are difficult times. This bill is just one more step in our policy of family law reform. We recognise that the system is fundamentally flawed. Today with this bill we take another step towards fixing the system, along with the introduction of a national network of family relationship centres, which I lobbied the Attorney-General and the members of the cabinet very hard for. Fortunately for Kingston we have been and will be successful. There is also the raft of family law amendments that have already been passed by this parliament. We seek to make family breakdowns something which is governed by a fair and equitable system and we seek to make them something which is in decline. What is more, this government has more to come. We will implement across-the-board reforms to the child support system in this country and we will continue to implement changes which seek to resolve disputes associated with family breakdown in an amicable way before they reach the courtroom. Never in Australia's history have we seen such a high level of family breakdown, and never in my history have I seen such animosity and genuine hatred between separating parents who at some point loved each other, created a child and brought a child into the world. These children are our future, and we cannot afford to experiment on them with a system that risks not affording them the right to develop a meaningful relationship with both their parents. We cannot know today what the impact of a failing family law system will be on our children and grandchildren. I for one would rather not find out. For that reason, I a huge supporter of this government's attempts to fix the system. For that reason, I commend the bill to the House.

Epidemiology has shown a link between low birth weight and the development of diabetes and cardiovascular disease. The relative contributions of genetic and environmental factors to this association have been debated, but remain to be established in the absence of compelling evidence implicating specific candidate genes. Evidence from human and animal studies suggests that manipulating the fetal environment `programmes' the fetus to develop chronic diseases in adulthood. This has given rise to the fetal origins hypothesis, which proposes that a stimulus in utero may permanently alter tissue structure and function. In this article, Drake and Walker review the evidence extending this hypothesis by considering transmission of fetal programming effects through subsequent generations. Thus, non-genetic mechanisms may contribute to the co-inheritance of a predisposition for low birth weight with cardiovascular disease.

Stirrer disks or pins ; fixed on a drive shaft. The grinding chamber is filled with small grinding media normally spherical annealed glass, steel, or ceramic beads ; at a high bead load. An intensive grinding action of slurry-bead mixture in the chamber is generated at a high stirring speed. The respective kind of flow determines the spatial distribution of zones with a high grinding intensity as well as the predominant types of grinding mechanisms and their composition Blecher et al, 1996; Kwade et al, 1996 ; . Thus, the predominant grinding mechanisms in stirred media mills are dependent on compressional, shear and torsional stresses, which are invoked by stirring the slurry-bead mixture at a very high velocity Kwade, 1999 a and b; Theuerkauf and Schwedes, 1999; Blecher et al, 1996; Gao and Forssberg, 1995; Orumwense and Forssberg, 1992 ; . The grinding process in a stirred media mill is usually determined by i ; how often each feed particle or a fragment arising from the feed particles is stressed i.e., the number of stress events ; and ii ; how high the stress intensity at each stress event is. In a batch grinding process, the average number of stress events of each product particle, SN, is determined by the number of media contacts, Nc, and by the probability that a particle is caught and sufficiently stressed at a media contact, Ps, and by the number of product particles inside the mill, Np. Thus, the average number of stress events of each product particle, SN, can be written by Kwade, 1999 a and b.

| Cycloserine moaEven if the pathogenesis of both CD and UC is still incompletely understood, the crucial role of T cells in the pathogenesis of IBD is beyond discussion. T cells originate in the bone marrow and mature in the primary lymphoid organs. For patrolling antigens in the gut lumen and for assisting in intestinal inflammatory reactions, they need to be directed toward the gastrointestinal tract. The journey of T cells from the blood to antigen-rich organs such as the gut or the lungs is, however, guided by an elaborate system of traffic signals or adhesion molecules. To encounter antigen and to engage in tissue inflammation, T cells must leave the blood stream. On average, they do not stay in the blood 30 min. Leukocytes engage with the endothelium of postcapillary vessels, the high endothelial venules, before they migrate into the tissue 27a ; . This interaction is hindered by the high relative speed at which T cells travel, creating an important shear stress in the blood stream. A highly effective and sequential adhesion system has emerged to overcome these physical forces. Initially, tethering occurs through the interaction between selectins L-, P-, and E-selectins ; and oligosacharide moieties acting as ligands 27 and cyclosporine.
