The healing process of some chronic leg ulcers may prove to be problematic. Success is in part conditioned by the interference of keratinocytes with both the bacterial flora present in the ulcer bed, and by the quality of the granulation tissue. The antiseptic activity of povidone-iodine (PVP-I) is acknowledged. We report the paradoxical facet of the beneficial cytotoxic effect of PVP-I on the healing process. The beneficial effect on blood vessels and dermal dendrocytes of the granulation tissue is also emphasized. [less ▲]

In the stoichiometric study of phyto-zooplankton interactions, a controversy exists about how Daphnia species regulate their feeding rate when submitted to low-quality food (i.e. high dietary carbon:phosphorus [C:P] ratio). In this study, we gathered data over 3 years on in situ clearance rates of a Daphnia galeata population, by conducting grazing experiments from April 1998 to October 2000 in the Esch-sur-Sure reservoir (Grand-Duchy of Luxembourg). Observed clearance rates (2.5-13.5 mL individual(-1) day(-1), mean 7.0 mL individual(-1) day(-1)) were correlated with population and environmental variables. Mean body size of Daphnia individuals was the best predictor of clearance rate (r(2) = 0.639), followed by water temperature (r(2) = 0.262) and P concentration in the seston (r(2) <= 0.241). When combined with body size, seston C:P or nitrogen:P ratios provided the best predictive regression model of clearance rate (r(2) = 0.852-0.897). The clearance rate was always correlated negatively with P concentration in the food. Thus, Daphnia reacts to a decrease of food quality (i.e. higher C:P ratio) by an increase of its feeding rate. However, the filtration response to food quality was inhibited by high population density. We suggest that, when food quality is low and population density high, this inhibition may favour fitness of future conspecific generations. In conclusion, our results emphasize the effect of P availability on transfer rate of organic matter between lacustrian autotrophs and herbivores and pose questions about consequent effects on nutrient biogeochemical cycles.

On day 30 after autologous peripheral blood stem cell transplantation (PBSCT), 20 patients were randomized to receive either erythropoietin at a dose of 500 U/kg/week s.c. (Epo group) or no treatment (control group). After 3 weeks, hemoglobin (p<0.0001) and serum transferrin receptor (p<0.0001) concentrations were higher in the Epo group. Hb response (+2 g/dL) was achieved in 100% vs 28% (p<0.0001) and Hb correction (> or =13 g/dL) in 70% vs 10% (p=0.0238) of the patients, respectively. This is the first randomized study showing an efficacy of erythropoietin therapy on Hb levels after autologous PBSCT. [less ▲]

Vascular brachytherapy (VBT) is the only proven treatment option for patients with in-stent restenosis. In seven randomised trials with almost 1500 patients that evaluated {gamma} (five studies) and ß (two trials) irradiation, target vessel failure reduction ranged from 73% to 34% by VBT compared with conventional angioplasty.1 However, the reported restenosis rates with the active treatment still varied between 17% and 32%.1 We therefore postulated that repeat VBT is safe and efficacious for preventing refractory in-stent restenosis in high risk patients with failed VBT. METHODS Beginning in January 1999, VBT was applied for all patients with in-stent restenosis. VBT was systematically performed with intravascular ultrasound (IVUS) guidance. The repeat procedure was performed with a strontium/yttrium-90 source train (BetaCath, Novoste, Norcross, Georgia, USA). The design and application of this catheter have been described previously.2 The dosimetry was based on the manufacturer’s recommendations but taking into account not the angiographic vessel reference diameter but the external elastic membrane diameter (as determined by IVUS). The mean dose delivered at 2 mm from the source centre was 23.3 (2.2) Gy during the index procedure and 25.3 (2.2) Gy during the repeat intervention. Percutaneous coronary intervention (PCI) was performed according to standard clinical practice. Failed VBT was defined as angina recurrence combined with target vessel failure (as documented by any repeat angiography: premature depending on early symptom recurrence or at the planned six month control). Repeat VBT was considered for patients estimated to be at high risk for refractory in-stent restenosis or if they had a prognostic risk—that is, diffuse or ostial in-stent restenosis or total occlusion, or proximal left anterior descending artery stenosis. Focal edge effect stenoses and non-prognostic lesion locations in symptomatic patients were treated by conventional PCI. Written informed consent was obtained from all patients before intervention. The study was approved by the hospital ethics committee. All VBT patients were prospectively entered in a dedicated database by a person not taking part in the interventions. A combined antiplatelet treatment (aspirin 100 mg and clopidogrel 75 mg daily) was prescribed for at least six months after the index procedure and for one year after the second VBT. Control angiography was mandatory at six months in all VBT patients and systematic long term clinical follow up was carried out. RESULTS Between July 1998 and March 2003, 251 VBT interventions were performed at our institution: 22 patients were treated for primary restenosis prevention and 229 patients for in-stent restenosis. VBT failed in 34 patients (14.8%): 23 underwent conventional PCI and 11 underwent repeat VBT. The baseline clinical and angiographic demographics were comparable for both groups. Concerning the repeat VBT group, mean (SD) age was 60 (7) years, nine patients were men, and two had diabetes. All patients who underwent a repeat procedure had incapacitating angina pectoris. Angina recurred at 7 (2) months (range 4–10) after the first, failed VBT. The restenosis pattern (table 1Go) was diffuse in the majority of patients at the first presentation and remained diffuse with exacerbation to total occlusion in two patients. In the focal restenosis group, two patients had ostial in-stent restenosis. The cause of recurrent in-stent restenosis was an evident geographical miss in two patients (a focal and a diffuse pattern case). IVUS and angioplasty were successful before irradiation therapy in all patients. During repeat VBT, a 40 mm source train was used in seven patients and a pullback technique was required in two because of the length of the restenotic segment. No additional stents were implanted and no evidence of geographical miss was seen at repeat intervention. Table 1Go shows quantitative coronary angiography and IVUS data. During the index procedure, the minimum in-stent luminal area increased from mean (SD) 5.8 (1.8) to 7.5 (1.4) mm2. This area was maintained at the repeat intervention at 7.8 (2.1) mm2 and further expanded to 8.9 (1.8) mm2. All repeat interventions were technically successful and there were no adverse clinical events during the in-hospital phase. [less ▲]

OBJECTIVES: To compare the values of the urodynamic parameters of the lower portion of the urinary tract and vaginourethral measurements obtained during the phases of the estrous cycle in dogs and determine possible functional or anatomic modifications of the lower portion of the urinary tract associated with those phases. ANIMALS: 7 adult female Beagles. PROCEDURE: Urethral pressure profilometry, diuresis cystometry, and vaginourethrography were performed in each dog during proestrus; estrus; early, mid, and late diestrus; and early and late anestrus. The maximum urethral pressure (MUP), maximum urethral closure pressure (MUCP), urethral functional and anatomic profile lengths (UFPL and UAPL, respectively), integrated pressure, threshold pressure, threshold volume, compliance, urethral length, and vaginal length and width were measured. RESULTS: For all measurements, significant interindividual variation was detected. Integrated and threshold pressures, APL, and each morphometric value significantly increased from late anestrus to proestrus. Compared with other phases, MUP, MUCP, and integrated pressure values were significantly lower in estrus and early diestrus; UAPL and UFPL values were significantly lower in late diestrus. At each cycle phase in old dogs, MUP, MUCP, threshold pressure, and vaginal length and width were significantly lower (except in proestrus for vaginal measurements) and threshold volume and compliance values were significantly higher, compared with middle-aged dogs. CONCLUSIONS AND CLINICAL RELEVANCE: Urodynamic and morphometric measurements of the lower portion of the urogenital tract are affected by the changes in hormonal balance that occur during the estrous cycle. In sexually intact female dogs, estrous phase determination is important for the interpretation of urodynamic data. [less ▲]

Facultative paedomorphosis is an environmentally induced polymorphism that results in the coexistence of mature, gilled, and fully aquatic paedomorphic adults and transformed, terrestrial, metamorphic adults in the same population. This polymorphism has been of interest to scientists for decades because it occurs in a large number of caudate amphibian taxa as well as in a large diversity of habitats. Numerous experimental and observational studies have been conducted to explain the proximate and ultimate factors affecting these heterochronic variants in natural populations. The production of each alternative phenotype is based on a genotype x environment interaction and research suggests that differences in the environment can produce paedomorphs through several ontogenetic pathways. No single advantage accounts for the maintenance of this polymorphism. Rather, the interplay of different costs and benefits explains the success of the polyphenism across variable environments. Facultative paedomorphosis allows individuals to cope with habitat variation, to take advantage of environmental heterogeneity in the presence of open inches, and to increase their fitness. This process is expected to constitute a first step towards speciation events, and is also an example of biodiversity at the intraspecific level. The facultative paedomorphosis system is thus ripe for future studies encompassing ecology, evolution, behaviour, endocrinology, physiology, and conservation biology. Few other systems have been broad enough to provide varied research opportunities on topics as diverse as phenotypic plasticity, speciation, mating behaviour, and hormonal regulation of morphology. Further research on facultative paedomorphosis will provide needed insight into these and other important questions facing biologists. [less ▲]
