During the last 10 years, the increased need for starches with novel properties has occupied the research community, and many efforts were concentrated on unraveling the starch bio- synthesis pathways. The knowledge generated in these investigations was subsequently used to produce tailor-made starches in higher plants using recombinant DNA technology. Examples of starches with new functionalities are those with a modified degree of branching (Schwall et al. 2000, Shewma- ker et al. 1994, Kortstee et al. 1996) and the amylose-free starch (Visser et al. 1991a, Kuipers et al.1994), some of which hold potential for applications in the paper-, textile-, plastics-, food and pharmaceutical industry. The accumulation of more starch has also been an objective, but this will not be dis- cussed further here, (see: Slattery et al. 2000). In our laboratory, we have embarked on two generic tech- nologies with a very wide range of applicability: (i) introduction of new linkages types and structural elements using glu- cansucrases, and (ii) engineering granule-boundness by using microbial starch-binding domains (SBDs). It is expected that these technologies will contribute substantially to the biosynthesis of more versatile α-glucans in the near future, leading to starches with altered functionalities that cannot be obtained by conventional breeding. In this study recent developments in starch modification using heterologous expression of microbial genes will be reviewed, with emphasis on the potato plant. [less ▲]

World population is ageing. This phenomenon is unprecedented, universal, long-lasting and has important implications. Unprecedented, because never before in human history, so many individuals have reached an advanced age. Universal, because all countries are now concerned. Long-lasting, because ageing started in the second half of the XXth century and will become even more pronounced over the XXIst century. With important implications, because it has and will have substantial consequences on human life and social composition. This article reviews quantitative data on ageing to appraise its extent and implication, the goal being to extend and stimulate the debate on ageing. International data are first presented, then analysis moves to Belgium estimates. [less ▲]

In less than ten years, a business property market has emerged in Wallonia. This market first concerned offices and retail units (a sector not studied in this paper) and, more recently, semi-industrial establishments. Its development is largely related to the creation of new demands in physical units, environment and accessibility, as well as in location choices, at both sub-regional and local scales. It has been favoured by the arrival of new property stakeholders from Belgium and abroad (developers, investors and property agents), as well as by public authorities (the Walloon Region and, more importantly, supra-communal, economic development agencies). The emergence of this market is related to the accentuation of territorial contrasts as property development projects usually reinforce strong area [less ▲]

Abstract The European Organization for Research and Treatment of Cancer (EORTC) 22861 randomised trial established that combined radiochemotherapy is the standard treatment for locally advanced anal cancer. This EORTC phase II study (#22953) tests the feasibility of reducing the gap between sequences to 2 weeks, to deliver Mitomycin C (MMC) in each radiotherapy sequence and 5-FU continuously during the treatment. The first sequence consisted of 36 Gy over 4 weeks. 5-FU 200 mg/m2/days 1–26, MMC 10 mg/m2/day 1 gap 16 days. Then a second sequence of 23.4 Gy over 17 days, 5-FU 200 mg/m2/days 1–17 and, MMC 10 mg/m2/day 1 was given. 43 patients with a World Health Organization (WHO) status of 0 (n=27) or 1 (n=16) and with T2-T4, N0-3 tumours were included. Compliance with the planned treatment, doses and duration was 93%. The complete response rate was 90.7%. Grade 3 toxicities of 28, 12 and 2% were observed for skin, diarrhoea and haematological toxicities, respectively. The 3-year estimated rates for trials 22861 and 22953 are: 68 and 88% for local control; 72 and 81% for colostomy-free interval, 62 and 84% for severe late toxicity-free interval, and 70 and 81% for survival, respectively. The 22953 scheme is feasible and the results are promising. This is now considered as the new standard scheme by the EORTC. [less ▲]

This chapter summarizes the various NMR experiments that were applied to probe the main stereochemical features of polymers prepared by ring-opening metathesis polymerization (ROMP) of 2,3-dicarboalkoxynorbornadienes and 2,3-dicarboalkoxynorbornenes catalyzed by the dichloro ruthenium arene dimer (RuCl2(p-cymene))2 in the presence of trimethylsilyldiazomethane (TMSD). Direct spectroscopic methods based on the examination of cross-coupling peaks in polymers derived from optically active monomers (1H COSY NMR) and indirect methods based on the analysis of the hydrogenated derivatives of unsaturated parent polyolefins (1H and 13C NMR) led to the same conclusion. They both showed that high trans, highly isotactic polymers were formed using the ruthenium-arene catalyst precursor. [less ▲]

Porcine PAG (pPAG) are placental products of a multigene family that is strongly expressed in the chorionic epithelium (trophoblast and trophectoderm). The objective of this study was to define a pattern of the pPAG proteins, secreted in vitro by chorionic explants harvested on 16-77 days of pregnancy. Trophoblastic and trophectodermal explants were collected from pregnant (PR) gilts (n = 27) and used for protein in vitro production (8-261 h). Endometrial explants of luteal-phase gilts (E10, n = 4) and pseudopregnant gilts (PsE, n = 2) were used as negative controls for protein immunoblotting. Proteins (PR, E10, PsE) were isolated mainly from incubation media, fractionated, dialysed and separated by SDS-PAGE. Heterogeneous Western blotting with various polyclonal anti-PAG sera raised against bovine or ovine antigens (anti-bPAG, or anti-oPAG) initially identified the pPAG proteins. Such blotting of fractionated chorionic proteins allowed for the isolation of porcine antigens that were employed as immunogens to raise several homologous antisera (anti-pPAG). Crude antisera were adsorbed on endometrial extracts or proteins of non-PR pigs, to remove non-relevant antibodies. The patterns of pPAG proteins secreted in Vitro varied throughout pregnancy (35-72 kDa). During implantation, similar to43 kDa (Day 16) or similar to68.1 kDa (Days 17-25) pPAG proteins were detected. During placentation and as pregnancy advanced (Days 31-77), similar to72.3 kDa pPAG proteins were observed. The secretions of parallel multiple smaller proteins (35.4-47.2 kDa), presumably, as forms of processed pPAG precursors, increased with the progress of gestation. In conclusion, the pPAG protein family plays a very important role during implantation, placenta formation and embryonic/foetal development in the pig. [less ▲]

Obesity and weight loss have been shown to alter thyroid hormone homeostasis in humans. In dogs, obesity is the most common nutritional problem encountered and weight loss is the cornerstone of its treatment. Therefore, it is important to clarify how obesity and weight loss can affect thyroid function test results in that species. The objectives of this study were to compare thyroid function in obese dogs and in lean dogs and to explore the effects of caloric restriction and weight loss on thyroid hormone serum concentrations in obese dogs. In the first experiment, 12 healthy lean beagles and 12 obese beagles were compared. Thyroid function was evaluated by measuring serum concentrations of total thyroxine (TT4), free thyroxine (FT4), total triiodothyronine (TT3), thyrotropin (TSH), and reverse triiodothyronine (rT3) as well as a TSH stimulation test using 75 mu g IV of recombinant human TSH. In the second experiment, eight obese beagles were fed an energy-restricted diet [average 63% maintenance energy requirement (MER)] until optimal weight was obtained. Blood samples for determination of TT4, FT4, TT3, TSH and rT3, were taken at the start and then weekly during weight loss. Only TT3 and TT4 serum concentrations were significantly higher in obese dogs as compared to lean dogs. In the second experiment, weight loss resulted in a significant decrease in TT3 and TSH serum concentrations. Thus obesity and energy restriction significantly alter thyroid homeostasis in dogs, but the observed changes are unlikely to affect interpretation of thyroid function test results in clinics.
