Crude locust bean gum (CLBG) was purified and fractionated into two parts : the first was obtained by solubilization in water at 25 °C (GM25) and the second consisted in a further extraction at 80 °C on the residual impoverished fraction (GM80). The complete structural characterization has shown that GM80 possessed relatively longer chain lengths than GM25, a slightly lower degree of galactose substitution and a somewhat sharper galactosyl distribution in substituted and unsubstituted regions. A physical behavior analysis was carried out on solubilization kinetics, viscosity, viscoelasticity and formation of associated gels with xanthan or carrageenan. The average structure of GM80 generated larger intra-chain, inter-chain and inter-molecular interactions, resulting in the appearance of a stronger network. Small structural differences therefore generated very different physical behaviors. This study thus allowed to establish, in a precise and complete manner, fractionation-purification-structure-function relationships of galactomannans extracted from carob. [less ▲]

BACKGROUND: In Belgium, regulations restrict the reimbursement of statins to patients with total serum cholesterol above 250 mg/dl (6.41 mmol/l) after a three-month lipid-lowering diet. We investigated the possible impact of these regulations on characteristics of Belgian patients receiving a lipid-lowering drug. DESIGN: From 1998 to 2000, standard questionnaires on coronary risk factors and treatments with lipid-lowering drugs were completed by 301 GPs sampled at random in the 11 Belgian Provinces. Questionnaires had to be completed for 18 consecutive patients 35 years old or more attending GPs' practices, irrespective of the underlying motive for attendance. RESULTS: Of the 5511 patients included in the study, 1519 (28%) had established coronary disease or diabetes mellitus, or > or = 2 non-cholesterol coronary risk factors. Most (70%) of these patients were not treated with a lipid-lowering drug. Only 22% of patients with established coronary disease, 10% of patients with diabetes mellitus and 9% of patients with > or = 2 coronary risk factors were treated with a statin. Fifty-nine percent of fibrate users and 50% of statin users had a pre-treatment cholesterol level above 250 mg/dl, but had no or only one non-cholesterol coronary risk factor. CONCLUSIONS: In Belgium, the majority of patients at higher risk of coronary event do not benefit from lipid-lowering drugs, particularly the statins. In contrast, one of two statin users and three of five fibrate users should probably not receive the drug prescribed. Regulation based on blood cholesterol level encourages the overlooking of other risk factors relevant for selecting patients having the greatest chance to benefit from statin treatment. [less ▲]

AIM: To determine the value of kidney revascularisation in patients with impaired renal function and correctable renal artery stenosis, the authors reviewed their surgical experience from 1978 to 1990. PATIENTS AND METHODS: The study population included 23 patients with ischaemic nephropathy whose preoperative baseline creatinine level exceeded 20 mg/l (range 21-65 mg/l). This represents 20% of all patients operated on for renal artery disease during the same time interval. Preoperative risk profile, operative mortality, impact on hypertension and on renal function, and late survival were analysed. Renal function response to kidney revascularisation was defined as favourable (20% or more reduction of serum creatinine), moderate (stabilised serum creatinine values) or bad (further deterioration of renal function). All patients had atherosclerotic renal artery disease, involving a solitary kidney in five, both kidneys in 15 and one of the two kidneys in three patients. Hypertension was present in 74%. Revascularisation was unilateral in 10, bilateral in nine and associated with controlateral nephrectomy in four patients. RESULTS: Four patients died postoperatively (three myocardial infarctions, one stroke). Four patients needed postoperative short-term dialysis. After operation, renal function improved in 13, stabilised in six and deteriorated in four patients (of whom two died). Follow-up among the survivors averaged 46 months. The mean serum creatinine value at last follow-up visit was 26.2 mg/l, a decrease of 7.7 mg/l compared to preoperative values (p < 0.05). Overall, 69% of azotemic patients submitted to renal revascularisation manifested a favourable response (45% improved and 24% stabilised). Three patients required long-term dialysis. The 5-year survival rate was 48%. CONCLUSION: These data suggest that kidney revascularisation in patients with ischaemic nephropathy can restore or stabilise renal function, preventing evolution and end-stage renal disease and dialysis dependency.

For pomerons described by a sum of two simple-pole terms, a soft and a hard pomeron, the unitarity bounds from saturation in impact-parameter space are examined. We consider the effect of these bounds on observables linked with polarisation, such as the analyzing power A(N) in elastic proton-proton scattering, for LHC energies. We obtain the s and t dependence of the Coulomb-nuclear interference at small momentum transfer, and show that the effect of the hard pomeron may be observed at the LHC. [less ▲]

Posidonia oceanica meadow is an endemic ecosystem of the Mediterranean coasts. A known threat to this ecosystem is aquaculture. In zones of intensive fish production, P. oceanica meadow tends to be less healthy or to disappear .One of the reasons for this is a decrease in the light that reaches the leaves (direct shading, increase of water turbidity or of epiphytic algae density). Unfortunately, when the meadow begins to die, it is often too late to act. So, people are trying to find indicators that react early to this kind of perturbations. In this framework, this study focuses on the impact of shading (without nutrient enrichment) on the meiofauna living in the surface sediment of a P. oceanica meadow. An in situ shading experiment was led from the end of May to the end of August 2009, at a depth of 10 m, in a reference P. oceanica meadow. Three shading nets were put in the meadow to reach a light extinction of 50%. A control site was also defined. The first two centimetres of sampled sediment cores were studied. After three months of shading, the total abundance of meiofauna at the shading site was lower than at the beginning of the experiment, while it stayed around the same level at the control site. This difference is mainly due to a decrease in the total number of foraminiferans, nematods, gnathostomulids, copepods and bivalves. However, no significant difference in diversity was observed. At the end of this experiment, it appeared that, contrarily to what is mostly said in the literature, the direct organic enrichment that occurs at fish farms is not the only reason to the modification of the meiofauna communities of the ecosystem. The shading by itself has also an effect. [less ▲]
