In Europe, because of previous intense forest use in the past centuries, the plantation of coniferous stands, especially Norway spruce with high production potential has been a common strategy. However, the characteristics of Norway spruce such a s susceptibility to windfall, forest dieback and soil acidification have caused negative ecological impacts at many sites. Conversion of conifers into deciduous or mixed stands has been suggested in order to improve ecological conditions and biodiversity o f forest ecosystems. In this study, six broadleaved species were planted at the same site, thus being subjected to similar condition in terms of soil type, land use history and climate. The aim of this research was to study of foliar nutrient status and nu trient return to the forest floor through litterfall 11 years after conversion of Norway spruce (Picea abie s (L.) KARST.) into a mixed stand with common alder (Alnus glutinosa (L.) GAERTN.), european beech (Fagus sylvatica L.), pedunculate oak (Quercus rob ur L.), silver birch (Betula pendula ROTH.), goat willow (Salix caprea L.) and rowan (Sorbus aucuparia L.). Our results revealed that tree species had a different foliar nutrient status and an effect on nutrient input fluxes through litterfall. For example , litter nutrient contents (N, Ca, Mg, K) were highest under alder, rowan and willow. Total litterfall and nutrient fluxes from leaf litter were highest under rowan. Our results demonstrate that, on poor sites, plantation of pioneer species, especially row an, may improve the nutrient status of the forest floor through higher input in litterfall. [less ▲]

Little by little, nanotechnology has emerged amid enormous anticipations and fantastic promises of new materials, aspiring to manipulate our world “atom by atom.” While these grand visions continue to capture the imaginations of various audiences—and continue to be contested, as well—nanotechnology has developed into more than that. During the last two decades, many research programs and industrial R&D expenditures have resulted in actual products and tangible innovations. Nanotechnology, it seems, is expanding. But what does it mean to say that nanotechnology is expanding? [less ▲]

This work starts from the consideration that the Christian liturgy plays a key role all over the Europe during the XII and XIII centuries. The aim of the study is to demonstrate that—at least for this reason—a high number of troubadours were influenced by the liturgy while composing a courtly song. In particular, the analysis shows the presence of liturgical traits since the first documented troubadour, i.e. William IX. Indeed, his works show his familiarity with the metrical and melodic structures of hymns and prosulae, as well as his knowledge about the cult of the saints in the area of Limoges. Moreover, the present study demonstrates the recollection of some prayers, liturgical formulae and Biblical excerpts in some troubadours, e.g. Marcabru and Peire d’Alvernhe; the correspondence between the believer’s and the poet’s gestures in Gaucelm Faidit’s texts; the influence of the sacraments—specifically the penitence—over most troubadours all over the XII and XIII centuries, and lastly the recurring employment of metaphors with a liturgical origin, such as the ‘fire of love’.

Taking into account the close antigenic relationship between bovine herpesvirus 1 (BoHV-1) and caprine herpesvirus 1 (CpHV-1), a live attenuated glycoprotein E (gE) negative BoHV-1 vaccine was assessed in goats with the aim to protect against CpHV-1 infection. Vaccine safety was evaluated by intranasal inoculation of two groups of goats with either a gE-negative BoHV-1 vaccine or a virulent BoHV-1. The length of viral excretion and the peak viral titre were reduced with the gE-negative vaccine. To assess the efficacy, two goats were inoculated intranasally twice 2 weeks apart with a gE-negative BoHV-1 vaccine. Four weeks later, immunised and control goats were challenged with CpHV-1. A 2 log(10) reduction in the peak viral titre was observed and the challenge virus excretion lasted 2 days more in immunised than in control goats. These data indicate the safety and the partial efficacy of a live attenuated gE-negative BoHV-1 vaccine intranasally administrated in goats. (c) 2005 Elsevier B.V. All rights reserved. [less ▲]

OBJECTIVE: To examine the factors associated with liver steatosis in severely obese subjects and to test the potential reversibility of fatty liver after weight loss. DESIGN: Retrospective clinical study. SUBJECT: 528 obese patients before bariatric surgery and 69 obese subjects of the initial cohort evaluated before and 27+/-15 months after gastroplasty. MEASUREMENTS: Fatty deposition (scored as mild, moderate or severe) and inflammatory changes were evaluated in liver biopsies; clinical (body mass index (BMI), age, gender, duration of obesity) and biological (glucose, triglycerides, liver enzymes) parameters were related to histological findings. RESULTS: 74% of the 528 biopsies showed fatty change, estimated as mild in 41% of cases, moderate in 32% and severe in 27%. The prevalence of steatosis was significantly higher in men than in women (91% vs 70%, P = 0.001) and in patients with impaired glucose tolerance or type 2 diabetes compared with nondiabetics (89% vs 69% P = 0.001). The severity of the steatosis was associated with BMI (P = 0.002) but not with the duration of obesity or the age of the patient. When compared with patients without fatty change, those with liver steatosis had significantly higher fasting plasma glucose (5.5 mmol/l vs 5.1 mmol/l, P = 0.007) and triglycerides (1.8 mmol/l vs 1.3 mmol/l, P = 0.002). Mean serum liver enzyme activities (alkaline phosphatase, aspartate aminotransferase (AST), alanine aminotransferase (ALT) and gamma-glutamyl-transpeptidase (gammaGT) were significantly (P < 0.001) increased in patients with fatty change but remained within laboratory reference values. In the 69 patients who have been evaluated after a marked weight reduction (-32+/-19kg), 45% of the biopsies were considered as normal (vs 13% before, P < 0.001) while pure fatty change was still observed in 38% of the patients (vs 83% before, P = 0.001). However, the severity of the steatosis was significantly (P < 0.001) reduced (mild: 62% vs 21%; moderate: 23% vs 37%; severe: 15% vs 42%). In addition, a significant increase of hepatitis was observed in 26% of the biopsies (vs 14% before, P < 0.05). CONCLUSIONS: Liver steatosis in obese subjects is associated with men, diabetic status, BMI, higher fasting glucose and hypertriglyceridaemia. Postgastroplasty weight loss reduces liver steatosis, but seems to increase the incidence of inflammatory lobular hepatitis. [less ▲]

Attempts to develop liver support systems for the treatment of patients with liver failure have ranged from use of plasma exchange to utilization of charcoal columns and extracorporeal devices loaded with liver tissue. However, no system has achieved wide clinical use and - in the absence of liver transplantation - severe hepatic failure continues to be associated with significant morbidity and mortality. In this paper, the authors review the current status of liver assist systems and summarize their clinical experience with a xenogeneic cell based-bioartificial liver. [less ▲]

The liver plays a key role in lipid metabolism. Depending on species it is, more or less, the hub of fatty acid synthesis and lipid circulation through lipoprotein synthesis. Eventually the accumulation of lipid droplets into the hepatocytes results in hepatic steatosis, which may develop as a consequence of multiple dysfunctions such as alterations in beta-oxidation, very low density lipoprotein secretion, and pathways involved in the synthesis of fatty acids. In addition an increased circulating pool of non-esterified fatty acid may also to be a major determinant in the pathogenesis fatty liver disease. This review also focuses on transcription factors such as sterol-regulatory-element-binding protein-1c and peroxisome proliferator-activated receptor alpha, which promote either hepatic fatty acid synthesis or oxidation.

In noncolorectal, nonendocrine liver metastases, the role of surgery is less define than in colorectal or neuroendocrine cancer. This role is marginal as liver is not the primary site of metastases of these cancers. Less than 2 to 5% of the patients with these malignancies might be one day considered as potential candidates for liver resection, as most patients suffer from extra hepatic tumour spread at the time they develop liver involvement. However, in these few cases with liver metastases only, as no other therapeutic option may provide mid- or long-term tumour-free survival, liver resection is indicated in resectable liver metastases. Some prognostic factors have been established in the literature from the few published series : unique versus multiple hepatic metastases, unilobar vs bilobar, metachronous vs synchronous, R0 vs R1 or R2 liver resections. The type of primary tumour is also of great importance, as cutaneous melanoma, pancreatic and gastric adenocarcinoma have a very bad prognosis for liver resection of metastases, even after R0 resection. In these cases, percutaneous or laparoscopic radiofrequency ablation may find its place. In sarcoma, breast carcinoma, uveal melanoma, and genitourinary cancers, liver resection may provide satisfactory long-term results in selected cases, and is the standard of care for isolated, resectable metastasis. However, due to the scarcity of indication of liver resection for noncolorectal, nonneuroendocrine metastases, the decision should be multidisciplinary, and the patients should be informed of the advantages and pitfalls of the surgical procedure.

Aim: Donation after cardiac death (DCD) has been proposed to partly overcome the organ donor shortage. In liver transplantation, the additional warm ischemia linked to DCD procurement may promote higher rate of primary non-function and ischemic type biliary lesions. In this study we reviewed the results of DCD liver transplantation at the University of Liège. Patients and Methods: From 2003 to 2007, 13 controlled DCD liver transplantations were consecutively performed. The records of all donors and recipients were retrospectively reviewed, particularly evaluating the outcome and the occurrence of biliary complications. Mean follow-up was 25 months. Results: Mean donor age was 51 years and their mean intensive care stay was 5.4 days. Mean time between ventilation arrest and cardiac arrest was 9.3 min. Mean time between cardiac arrest and arterial flush was 7.7 min. No touch period was 2 to 5 min. Mean graft cold ischemia was 295 min and mean suture warm ischemia was 38 min. Postoperatively there was no primary non-function. Mean peak transaminase was 2,546 UI/ml. Patient and graft survival was 100% at one year. Two patients (15%) developed graft main bile duct stenosis and underwent endoscopic management. No patient developed symptomatic intrahepatic bile duct strictures or needed retransplantation in the follow-up. Conclusions: The experience of the transplantation department of the University of Liege confirms that controlled DCD donors may be a valuable source of transplantable liver grafts, in case of short procurement warm ischemia and short transplant cold ischemia.

Hepatitis B (HBV) reactivation induced by chemotherapy is problem encountered recently in the management of malignant diseases. Chemotherapy-induced HBV reactivation may ultimately lead to terminal acute liver failure. Liver transplantation (LT) currently remains the only definitive treatment option for such cases, but is generally denied to patients suffering from malignancy. Here, the authors describe 2 cases of cancer-free and HBV graft re-infection-free survival after LT performed for terminal liver failure arising from HBV reactivation induced by chemotherapy for advanced stage lymphoma. These 2 cases, and some other reports in the literature, may suggest that patients suffering from hematologic malignancies and terminal liver disease can be considered for LT if the prognosis of their hematologic malignancy is good.
