Was repeated only as clinically indicated. Duodenal bile acid levels were measured at entry and at two years. Samples were stored at 70C and analyzed for ursodeoxycholic acid by high-performance liquid chromatography in the laboratory of Dr. Alan Hofmann at the University of California, San Diego, with previously validated methods.20 The protocol originally called for three years of recruitment and a minimum of two years of follow-up. Recruitment declined after the first year, and the accrual period was extended, with the approval of the institutional review board, to six years. Statistical Analysis In the primary analysis we compared the time to treatment failure using methods for censored survival data.21 Data on patients in whom treatment failure did not occur were censored at the time of the last follow-up visit. Event-free survival in the two groups was estimated by the KaplanMeier method and compared between groups with use of the two-sample log-rank test. We also adjusted for potential imbalances in the stratification variables by estimating treatment effect in a Cox proportional-hazards regression model that included the strata as covariates. Two-sample t-tests or Wilcoxon rank-sum tests were used to examine differences between treatment groups with respect to changes in biochemical values from base line to one and two years. Statistical tests were conducted at a two-sided alpha level of 0.05. With the observed accrual rates and an estimated survival free of treatment failure of 3.3 years in the placebo group, the study had approximately 70 percent power to detect a hazard ratio of 2.0 placebo: ursodiol ; with 51 subjects per group and approximately 90 percent power to detect a hazard ratio of 2.5.

Reduced hyaluronan turnover in myofibroblasts to the cells in culture, confirmed that fibroblasts degraded HA more readily than myofibroblasts. The principal enzymes involved in the turnover of HA are the hyaluronidase HYAL ; group of enzymes 10, 23, 24 ; . There are several HYAL genes but only three HYAL 1, HYAL 2 and HYAL 3 ; encode proteins that are broadly expressed in somatic tissues. HYAL 1 is ubiquitously expressed and is found in urine and circulating in plasma 25, 26 ; . It is also a lysosomal enzyme, which cleaves HA to small disaccharides. In contrast, HYAL 2 is anchored to the plasma membrane by a GPI-anchor and cleaves HA at a much slower rate to a limit product of ~ 50 disaccharides ~20 kDa ; 27 ; . Enzyme activity for HYAL 3 has not been described.

Intended Use: In the treatment of infertile couples by ICSI, PICSI is indicated for the selection of mature sperm for injection. Device Description: The PICSI Sperm Selection Device is a sterile, plastic culture dish with three microdots of hyaluronan hydrogel attached to the bottom interior of the dish. It also has three locating lines embossed on the bottom exterior of the dish to aid the operator to find the microdots. Mature human sperm attach themselves to the hyaluronan through specific receptors found on the sperm plasma membrane. Hyaluronan-bound sperm exhibit no progressive movement, although their tails beat and they are capable of motility. Hyaluronan-bound sperm are easily selected and removed from the hyaluronan by micropipet for use in intracytoplasmic sperm injection ICSI ; . PICSI dishes are radiation sterilized to provide a Sterility Assurance Level of 10-6. The endotoxin content is less than 1 EU device and dishes have been tested by 1-Cell Mouse Embryo Assays to demonstrate 75% conversion to blastocysts in 96 h. Storage and Handling: Store PICSI in a cool, dry location; prolonged storage at high temperature and humidity can reduce shelf life. Do not remove the device from its pouch until ready for use. Use immediately after removing the dish from its pouch. Preparation for use: Hydrate the hyaluronan microdots by placing single droplets of Human Tubal Fluid HTF ; or other suitable sperm diluent at the end of each locating line toward the center of the dish, see Figure 1. At your option, you may also place drops of PVP or other viscous sperm manipulation media elsewhere on the dish for collecting and processing PICSI-selected sperm. Carefully flood the dish with room temperature 18-28 C ; tissue culture oil. DO NOT USE 37 C OIL. The binding of sperm to the hyaluronan microdot is reduced at temperatures above 30 C. Maintain the dish at room temperature and use within 2 h of dot hydration. Using the dish: Add 1 to 2 prepared sperm to the first HTF drop. Allow at least 5 min. for the sperm to bind to the hyaluronan microdot. Place the dish on the microscope and observe the microdot and the density of sperm bound to it. Over time, the number of bound sperm will increase as more sperm contact the microdot and hydrocortisone.

Hyaluronan hyaluronic acid HA ; is a negatively charged, high molecular-mass polysaccharide found predominantly in the extracellular matrix ECM ; . Under physiologic conditions, hyaluronan exists as a high molecular weight polymer in excess of 106 Da. It does not induce inflammatory or proliferative genes as a native high molecular mass polymer. However, recent studies have found that low molecular weight hyaluronan fragments accumulate in tissues after injury 1, 2 ; . These low molecular weight hyaluronan fragments have been shown to be capable of activating macrophages and inducing the expression of genes whose functions are relevant to chronic inflammation 3 ; . Hyaluronan turnover and degradation increase during inflammation and lower molecular weight species of hyaluronan accumulate. Importantly, this accumulation is detected prior to the influx of inflammatory cells and deposition of collagen which suggests that low molecular weight hyaluronan accumulation is an early event in the development of inflammatory pulmonary disease 4 ; . Although the mechanisms of hyaluronan turnover and degradation are still unknown, it is generally accepted that free radicals, especially the highly reactive hydroxyl radical, play an important role in the degradation process of hyaluronan 5, 6 ; . Uchiyama et. al. showed that the oxidative reductive depolymerization reaction of hyaluronan proceeds essentially by random destruction of unit monosaccharides due to oxygen-derived free and hydromorphone.

Categories was related to the number of working persons; i.e. 2 women and 1.6 men for the resource-rich households, 1.5 women and 1.3 men for the medium-resource and 1 woman and 1 man for the resource-poor household Nkuba, 1997 ; . 6.2.5 Objective functions The objective functions in the model were selected based on the outcome of the land use and nutrient balance study Chapter 2 ; , and on farmer's expectations from use of herbaceous legumes Chapter 3 ; . They relate to optimisation of: - maize production kg for whole kikamba area over a complete rotation cycle ; - manure production kg for whole kikamba area over a complete rotation cycle ; and - N balance kg for whole kikamba area over a complete rotation cycle ; Although the kikamba was also indicated to have negative balances of P and K Chapter 2 ; , in the present study only N was considered because it is the only nutrient that can be externally added to the system by herbaceous legumes through biological N2-fixiation. In the present study, the N balance was partial and defined as the difference between the N inputs through mineral and organic fertilisers ; and outputs harvested crops and crop residues removed from the field ; in the crop rotation. 6. 3 Optimisation results 6.3.1 The maximum attainable N balances, maize and manure production The maximum attainable N balances with no restrictions on the other objectives, in the so called zero rounds Veeneklaas, 1990 ; , were 55, 44 and 30 kg per rotation for the resource-rich, medium and resource-poor households, respectively Table 6.5 ; . The corresponding maize production at these N balances was 3106, 2530 and 1763 kg per rotation while manure production was 762, 624 and 442 kg for the respective household categories Optimisation 1 ; . The maximum attainable maize production without restrictions on other objectives was 3430, 2674 and 1822 kg for resource-rich, medium and resource-poor household, respectively. In this situation, positive Nbalances of 25, 35 and 28 kg and manure production of 895, 705 and 459 kg per rotation were achieved by the respective household categories Optimisation 2 ; . The maximum manure production with no restrictions on the other objectives was 3839 kg for the resource-rich, 2942 kg for medium-resource and 1942 kg for the resource-poor household Optimisation 3 ; . These levels of manure production corresponded to Nbalances of -93 for the resource-rich, -76 for medium-resource and -50 kg for the resource-poor households and hydroxyurea.
