The efficacy of emamectin benzoate against infestations of Lepeophtheirus salmonis on farmed Atlantic salmon (Salmo salar L) in Scotland, 2002-2006
No full textInfestations of the parasitic copepod Lepeophtheirus salmonis, commonly referred to as sea lice, represent a major challenge to commercial salmon aquaculture. Dependence on a limited number of theraputants to control such infestations has led to concerns of reduced sensitivity in some sea lice populations. This study investigates trends in the efficacy of the in-feed treatment emamectin benzoate in Scotland, the active ingredient most widely used across all salmon producing regions. Study data were drawn from over 50 commercial Atlantic salmon farms on the west coast of Scotland between 2002 and 2006. An epi-informatics approach was adopted whereby available farm records, descriptive epidemiological summaries and statistical linear modelling methods were used to identify factors that significantly affect sea lice abundance following treatment with emamectin benzoate (SLICEH, Schering Plough Animal Health). The results show that although sea lice infestations are reduced following the application of emamectin benzoate, not all treatments are effective. Specifically there is evidence of variation across geographical regions and a reduction in efficacy over time. Reduced sensitivity and potential resistance to currently available medicines are constant threats to maintaining control of sea lice populations on Atlantic salmon farms. There is a need for on-going monitoring of emamectin benzoate treatment efficacy together with reasons for any apparent reduction in performance. In addition, strategic rotation of medicines should be encouraged and empirical evidence for the benefit of such strategies more fully evaluated

Madagascar NE, Anjanaharibe Sud, 14.7502 o S, 49.4998 o E +/- 0.8 km, 95 m +/- 50 m. Diagnosis. The combination in Ht. mimetica of the space-M 3 as well as space-CuA 1 ocellus expressed on the HWD and a white-translucent ocellus ring (hereafter ‘Orng’) extended close to the base of space M 3 and CuA 1 in the FWD, forming a rectangle, as in some forms of Ht. turbans, is diagnostic for this species for both known populations. In the closely related allospecies Ht. cowani, the Orng is nearly circular for all known populations. This trait is consistent in all Ht. mimetica. Description. Wings. Upperside uniform mid brown, except light brown in the area around the expressed ocelli of HWD where the ventral white area shows through. On FW, space-MI ocellus expressed as conspicuous white spot. Space-CuA 1 ocellus has narrow whitish-orange ring set in a somewhat rectangular white-translucent area whose lower proximad corner extends close to the base of space-CuA 1, as in Ht. sabas (Oberthür, 1923) (Fig. 2 E), rather than Ht. cowani (Fig. 2 C-D Fianarantsoa material). Only two ocelli are conspicuously expressed in HWD, that of space-M 3 and space-CuA 1, both subelliptic and surrounded by a similarly shaped light orange ring. HW margin has two conspicuous mid brown Smls (submarginal lines) following the somewhat crenate margin, slightly more crenate than typical in Ht. cowani. Ocellus expression on ventral surface similar but additional one in HW space-Rs of similar size to those of space-M 3 and space-CuA 1, and in each case surrounded by a pale orange and a wider light brown ring, the three set in a white-translucent and irregularly ‘X’-shaped area extending from the HW costa to mid space-CuA 2, one outer arm of the ‘X’ petering out distad of ocellus space-M 3. Basal area of HW mid brown, irrorated with areas of whitish scaling, and forming a right angle where the basal pattern meets vein M 2. Two bands of light brown and whitish irroration are found in the basal area of the FW together with a large whitish blotch proximad of white spot in space-M 1 and tapering towards the costa from around 2 / 3 along FW costa. Ht. cowani is almost identical in patterning on either surface except for the proximad extension of the whitish part of the Orng, which is fairly circular in Ht. cowani. Variation. Not much variation is evident between individuals of Ht. mimetica and there only one ♂ was dissected. Sexes similar, but ♀ larger, and may have more extensive white area near FW ventral apex. Wingspan/fwl: range 38–43.5 (n= 5 ♂♂)/ 20.3–24.3 mm (n= 7 ♂♂); mean= 40.5 +/- 2.2 SD (n= 6 ♂♂)/ 22.6 +/- 1.3 SD mm (n= 8 ♂♂), including referred specimen and HT ♂, 43.5 / 23.5 mm. Range 43–47 / 24.2–25.4 mm (n= 3, ♀♀); mean = 44.7 +/- 2.08 SD/ 24.7 +/- 0.62 mm (n= 3 ♀♀). Androconia: simple mid brown discocellular brush extending only slightly beyond the fork of Rs and M 1, underlying patch light ochreous grey and ‘bullet’-shaped (distally truncate to barely beyond the fork), surrounded by glossy dark scales which extend half way to costa and a similar extent in the other direction, as in Ht. cowani. Palps: from LV, light brown stripe in middle, bordered by two white stripes, and dark brown striped fringes of scales to edges, the edge potentially brushing the interommatidial setae consisting of longer scales. ♂ genitalia: 278 DL, PT (Fig. 5 A, LV, DV). Tegumen with fairly straight dorsal profile from LV, where it is relatively quadrate (slight proximad notch from DV). Gnathos narrow with small rounded projection distad at base arising almost perpendicular to base of uncus in its porrect position and curving strongly towards its forwardprojecting and pointed tips (from DV gnathos bends in and out strongly from its stout base). Vinculum strongly arched proximad with moderate constriction with tegumen. Valves with strongly rounded ‘shoulder’ at base, broad throughout with valve arm not much less broad than valve base, fairly parallel sided and spatulate, tips extending further than maximum extension of uncus, with an area of spinoid setae on inner face of tip (not as extensive as in Ht. cowani and Ht. exocellata; Lees, 1997: 104) and with tip incurved from DV. Saccus fairly long (longer than in Ht. cowani and Ht. exocellata) and inflated towards tip, while juxta is quite broad and down-lipped proximad. Aedeagus narrowly cupped beyond ostium and quite recurved away from body, fairly thin and parallel-sided. Etymology. Refers to the seemingly dual mimetic colour pattern (Fig. 2), on the upperside to Ht. sabas (Fig. 2 E), and on the underside to some forms of Ht. antahala (Ward, 1872) (Fig. 2 F); some Strabena species such as S. consobrina Oberthür 1916 and S. nepos Oberthür 1916 exhibit similar HWV patterns (see e.g. d’Abrera, 1997). In these butterflies, there is a similar configuration on the underside of ocelli set in a mainly white area. Unlike in most of the Ht. strigula group, but as in others of the Ht. exocellata group, and in some other more early diverging clades of Heteropsis, the HW space-M 3 ocellus is expressed. Discussion. This species was first recognized in the field by Claire Kremen at Anjanaharibe Sud in November 1995 (Lees 1997: 65). All specimens including the one referred specimen from Makira show the same wing pattern morphology, with no tendency to variation towards all known specimens of Ht. cowani in BMNH and MNHN from Fianarantsoa (Fig. 2 C-D), Ranomafana, Andrambovato or other collected localities of author or others (Vohiparara/ Sahavondronina, Ambondrombe, Anjozorobe). In Ht. cowani, the shape of the space-CuA 1 ocellus is always with a near-concentric orange ocellus ring. All relevant types were examined. The LT ♂ of Pseudonympha cowani Butler, 1880 is here designated as the specimen (Fig. 2 C) bearing labels “ Lectotype | Type /♂ Pseudonympha cowani Butl. |Male Fianarantsoa Madagascar, Coll. & pres. By W. D. Cowan 8-23.|B.M. TYPE No. Rh 3070 Pseudonympha cowani, Butl. ♂/ Pseudonympha Cowani Butler Type ”; the PLT becomes the ♀ with the same locality data that was photographed by B. d’Abrera 77 / 78 (d’Abrera 1980: 183). The two syntypes of Culapa houlbertiana Oberthür, 1923: 127, pl. 569, figs 4909, 4910 from ‘Fianarantsoa’, were also examined; the ♂ specimen, that is here designated the lectotype (Fig. 2 D), bears the data “ Lectotype | Madagascar Fianarantsoa ex Lamberton, 1922 |A servi de modele a J. Culot, pour le No. 4909 de la Pl. DLXIX Vol. XXI. Etudes de Lepidopterologie comparee|Ex Oberthür Coll. Brit. Mus. 1927 - 3.”. Automatically PLTs become two ♀♀ bearing labels “ Madagascar Fianarantsoa ex Lamberton, 1922 |Ex Oberthür Coll. Brit. Mus. 1927 - 3.”. The nominal species C. houlbertiana is clearly synonymous with Ht. cowani (Lees, 1997: 60–61; Lees et al., 2003: note 31). Additional information. DNA divergences: COI- 5 P cluster number BOLD:ACW 4993 (BMAD 261 - 15, CK 510) is shared with and 0.052 % divergent to that of Ht. cowani (BMAD 122 - 15, DL 14 Z-050, Anjozorobe), whereas about 10 % divergent to Ht. exocellata (FJ 666704, 549 bp compared). There is limited evidence so far of haplotype fixation. Where in the 434 th and 439 th nucleotide position of the DNA barcode, Ht. cowani has a G and a C (as in Ht. exocellata), Ht. mimetica has an A and a C (n= 2 in both cases). This is then a case of virtual barcode sharing with morphological divergence. More detailed genetic studies are required to investigate further this species pair. Phylogeny/sister species: sister species is Ht. cowani. Ecology and distribution. Habitat: found in Makira in a rather open forest structure dominated by Uapaca Baill. (Phyllanthaceae) growing on quartzite substrate, next to a stream (pers. obs.). Similar habitat on quartzite exists in Anjanaharibe Sud, and it is possible that such forest on poor substrates has an unusually light-penetrating nature. Behaviour: flies low, apparently mimetic of Ht. sabas in flight, as first noted by Claire Kremen (pers. comm.). All individuals were caught low down along or near the path; Ht. mimetica, like Ht. cowani, seems reluctant to come to fruit bait. The key functional aspect of this whitening seems to be translucence, which in sunspots seems to make the space-CuA 1 ocellus stand out in a more (frightening?) way. Translucence may also be an aspect to the wing pattern convergence for the HW, considering the HWV pattern is visible on the upperside. Hostplant: unknown, but presumed to be grasses (rather than bamboos), which are also frequented by Ht. cowani. Early stages: unknown, apart from one expressed egg (not described here). Distribution: replacement species of Ht. cowani endemic to the rainforest of northeast Madagascar and apparently extremely localized, known from only two very localised sites (Fig. 30 A, yellow dots). The species was searched for in its type locality in November 2014, at a similar date to the HT specimen, without success. Conservation: highly range restricted, but the species is currently protected by two parks. Elevational range: 775–950 m (n= 18 incl. observations).

Assessment of the polyphenol recovery from white wine lees via non-ionic polymeric resins
No full text[EN] Wine lees, a significant by-product of the wine industry, are an underutilized but valuable resource for nutraceutical recovery, as they are rich in bioactive compounds, particularly polyphenols. This study introduces a
novel and eco-friendly method for extracting and purifying polyphenols from white grape wine lees. Solid-liquid
extraction was conducted using water and a 25 % w/w ethanol-water hydroalcoholic solution, resulting in
aqueous (Aq) and hydroalcoholic (HA) extracts. Five food-grade, non-ionic polymeric resins (XAD7HP,
XAD16HP, MN202, PAD900, and PAD950) were evaluated for polyphenol purification. Resin MN202 emerged as
the most effective for this purpose.
Under static conditions with the Aqueous extract, the MN202 resin achieved an adsorption ratio (AR) of up to
60.5 % and a desorption ratio of 97.9 %, yielding a total adsorption-desorption efficiency (TADY) of 59.2 %. In
contrast, the TADY for glucose and fructose was minimal at just 0.36 % and 11.25 %, respectively, highlighting
the resin¿s high selectivity for separating polyphenols from sugars. Adsorption isotherms (Langmuir, Freundlich,
Sips, and Redlich-Peterson) followed the Langmuir isotherm model, indicating monolayer adsorption. Both
adsorption and desorption conformed to pseudo-second-order kinetics, dominated by multilayer intraparticle
diffusion. Under dynamic conditions, polyphenol recovery decreased to 44 %, though the purified polyphenols
remained suitable for high-value applications. Overall, this process potentially provides a promising and sustainable approach for recovering polyphenols from wine lees, with strong potential for scaling and use in nutraceutical and antioxidant products.The author Martina Gagliano ` acknowledges the University of Calabria and POR

Defining Comprehensive Disease Control for Use as a Treatment Target for Ulcerative Colitis in Clinical Practice: International Delphi Consensus Recommendations
No full textBackground and Aims: Treatment of ulcerative colitis [UC] requires a patient-centric definition of comprehensive disease control that considers improvements in aspects not typically captured by classical landmark trial endpoints. In an international initiative, we reviewed aspects of UC that affect patients and/or indicate mucosal inflammation, to achieve consensus on which aspects to combine in a definition of comprehensive disease control, using a modified Delphi process. Methods: The Delphi panel comprised 12 gastroenterologists and one patient advocate. Two gastroenterologists were elected as chairs and did not vote. To inform statements, we asked 18 patients and the panel members about their experiences of remission and reviewed published literature. Panel members voted on statements anonymously in three rounds, with a live discussion before Round 3. Consensus was met if ≥67% of the panel agreed. Statements without consensus in Rounds 1 and 2 were revised or discarded after Round 3. Results: The panel agreed to measure individual patient benefit using a definition of comprehensive disease control that combines aspects currently measured in trials [rectal bleeding, stool frequency, disease-related quality of life, endoscopy, histological inflammatory activity, inflammatory biomarkers, and corticosteroid use] with additional patient-reported symptoms [bowel urgency, abdominal pain, extraintestinal manifestations, fatigue, and sleep disturbance]. The panel agreed on scoring systems and thresholds for many aspects. Conclusions: Using a robust methodology, we defined comprehensive disease control in UC. Next, we will combine the measurement and scoring of these aspects into a multicomponent tool and will adopt comprehensive disease control as a treatment target in clinical practice and trials.</p
Mismatch-based delayed thrombolysis: a meta-analysis
No full text<p><b>Background and Purpose</b>: Clinical benefit from thrombolysis is reduced as stroke onset to treatment time increases. The use of "mismatch" imaging to identify patients for delayed treatment has face validity and has been used in case series and clinical trials. We undertook a meta-analysis of relevant trials to examine whether present evidence supports delayed thrombolysis among patients selected according to mismatch criteria.</p>
<p><b>Methods</b>: We collated outcome data for patients who were enrolled after 3 hours of stroke onset in thrombolysis trials and had mismatch on pretreatment imaging. We selected the trials on the basis of a systematic search of the Web of Knowledge. We compared favorable outcome, reperfusion and/or recanalization, mortality, and symptomatic intracerebral hemorrhage between the thrombolyzed and nonthrombolyzed groups of patients and the probability of a favorable outcome among patients with successful reperfusion and clinical findings for 3 to 6 versus 6 to 9 hours from poststroke onset. Results are expressed as adjusted odds ratios (a-ORs) with 95% CIs. Heterogeneity was explored by test statistics for clinical heterogeneity, I2 (inconsistency), and L’Abbé plot.</p>
<p><b>Results</b>: We identified articles describing the DIAS, DIAS II, DEDAS, DEFUSE, and EPITHET trials, giving a total of 502 mismatch patients thrombolyzed beyond 3 hours. The combined a-ORs for favorable outcomes were greater for patients who had successful reperfusion (a-OR=5.2; 95% CI, 3 to 9; I2=0%). Favorable clinical outcome was not significantly improved by thrombolysis (a-OR=1.3; 95% CI, 0.8 to 2.0; I2=20.9%). Odds for reperfusion/recanalization were increased among patients who received thrombolytic therapy (a-OR=3.0; 95% CI, 1.6 to 5.8; I2=25.7%). The combined data showed a significant increase in mortality after thrombolysis (a-OR=2.4; 95% CI, 1.2 to 4.9; I2=0%), but this was not confirmed when we excluded data from desmoteplase doses that were abandoned in clinical development (a-OR=1.6; 95% CI, 0.7 to 3.7; I2=0%). Symptomatic intracerebral hemorrhage was significantly increased after thrombolysis (a-OR=6.5; 95% CI, 1.2 to 35.4; I2=0%) but not significant after exclusion of abandoned doses of desmoteplase (a-OR=5.4; 95% CI, 0.9 to 31.8; I2=0%).</p>
<p><b>Conclusions</b>: Delayed thrombolysis amongst patients selected according to mismatch imaging is associated with increased reperfusion/recanalization. Recanalization/reperfusion is associated with improved outcomes. However, delayed thrombolysis in mismatch patients was not confirmed to improve clinical outcome, although a useful clinical benefit remains possible. Thrombolysis carries a significant risk of symptomatic intracerebral hemorrhage and possibly increased mortality. Criteria to diagnose mismatch are still evolving. Validation of the mismatch selection paradigm is required with a phase III trial. Pending these results, delayed treatment, even according to mismatch selection, cannot be recommended as part of routine care.</p>
Thrombolysis is associated with consistent functional improvement across baseline stroke severity: a comparison of outcomes in patients from the Virtual International Stroke Trials Archive (VISTA)
No full text<p><b>Background and Purpose:</b> Baseline stroke severity predicts outcomes among thrombolysed patients. The baseline National Institutes of Health Stroke Scale (NIHSS) thresholds are sometimes used to select patients for thrombolysis, clinical trial enrollment, or both. Using data lodged with Virtual International Stroke Trials Archive, we compared adjusted outcomes between thrombolysed and nonthrombolysed patients enrolled in neuroprotection trials (1998-2007) to assess the influence of various levels of baseline NIHSS.</p>
<p><b>Method:</b> We assessed the association of treatment with outcome, measured across the modified Rankin scale score distribution, in patients categorized by baseline NIHSS in increments of 4. We used an age and baseline NIHSS adjusted Cochran-Mantel-Haenszel test followed by proportional odds logistic regression analysis. We report the Cochran-Mantel-Haenszel P values and estimated odds ratios (OR) for improved modified Rankin scale score distribution with treatment for patients within each baseline NIHSS category.</p>
<p><b>Results:</b> Data were available for 5817 patients (1585 thrombolysed and 4232 nonthrombolysed). Baseline severity was greater among thrombolysed than nonthrombolysed (median baseline NIHSS, 14 vs 13; P<0.05). An association of treatment with outcome was seen independently and was of similar magnitude within each of the baseline NIHSS categories 5 to 8 (P=0.04; OR, 1.25; 95% confidence interval [CI], 1.0-1.6; N=278/934 thrombolysed/nonthrombolysed), 9 to 12 (P=0.01; OR, 1.3; 95% CI, 1.1-1.6; N=404/942), 13 to 16 (P<0.05; OR, 1.6; 95% CI, 1.3-2.1; N=342/814), 17 to 20 (P<0.05; OR, 1.7; 95% CI, 1.3-2.1; N=311/736), and 21 to 24 (P<0.05; OR, 1.6; 95% CI, 1.1-2.1; N=178/466). No association was observed within baseline NIHSS categories 1 to 4 (P=0.8; OR, 1.1; 95% CI, 0.3-4.4; N=8/161) or >= 25 (P=0.08; OR, 1.1; 95% CI, 0.7-1.9; N=64/179).</p>
<p><b>Conclusions:</b> In this nonrandomized comparison, outcomes after thrombolysis were significantly better than in untreated comparators across baseline NIHSS 5 to 24. The significant association was lost only at extremes of baseline NIHSS when sample sizes were small and confidence limits were wide.</p>
