Distribution of Pholeter gastrophilus (Digenea) within the stomach of four odontocete species: the role of the diet and digestive physiology of hosts
2005
We compared the distribution of the digenean Pholeter gastrophilus in the stomach of 27 harbour porpoises, Phocoena phocoena, 27 striped dolphins, Stenella coeruleoalba, 18 bottlenose dolphins, Tursiops truncatus, and 100 long-finned pilot whales, Globicephala melas. The stomach of these species is composed of 4 chambers of different size, structure and function. In all species, P. gastrophilus was largely restricted to the glandular region of the stomach, but the parasite tended to favour the fundic chamber in bottlenose dolphins and harbour porpoises, the pyloric chamber in pilot whales, and none in striped dolphins. However, predictability at infrapopulation level was generally low, sugg…
Seroprevalence of Toxoplasma gondii antibodies in wild dolphins from the Spanish Mediterranean coast.
2004
Although Toxoplasma gondii infection has been found occasionally in cetaceans, little is known of the prevalence of antibodies to T. gondii in wild dolphins. Antibodies to T. gondii were determined in serum samples from 58 dolphins stranded in the Spanish Mediterranean coast. Modified agglutination test was used to determine T. gondii antibodies, and a titer of 1:25 was considered indicative of T. gondii infection. Antibodies to T. gondii were found in 4 of 36 striped dolphins (Stenella coeruleoalba), in 2 of 4 common dolphins (Delphinus delphis), in 4 of 7 bottlenose dolphins (Tursiops truncatus), and in 1 harbour porpoise (Phocoena phocoena). Antibodies were not found in 9 Risso's dolphin…
Phosphoenolpyruvate Carboxylase Activity and Malate Content of Spruce Needles of Healthy and Damaged Trees at Three Mountain Sites
1991
Summary Investigations were carried out on the phosphoenolpyruvate carboxylase (PEPC) activity and the malate content in spruce trees [Picea abies (L.) Karst] at three natural sites. In needles of damaged spruce the PEPC activity is significantly higher than in needles of undamaged spruce. Therefore, the PEPC activity seems to be a biochemical damage indicator in spruce needles. The increase in PEPC activity in damaged trees is discussed as a repair mechanism to compensate the increased need of carbon skeletons by providing oxaloacetate. The malate content is enhanced in needles of severely damaged trees. An increase in malate seems to indicate senescence reactions and may be related to the…
Fetal Urogenital Sinus with Consecutive Hydrometrocolpos because of Labial Fusion: Prenatal Diagnostic Difficulties and Postpartal Therapeutic Manage…
2006
<i>Objective:</i> To elucidate the differential diagnoses of tumorous dilations in the fetal pelvic region detected by prenatal ultrasound and the postnatal management demonstrated on a fetus with 29 weeks of gestation with a retrovesical located bottle-like cystic structure measuring 54 × 31 × 27 mm within the pelvis. Postnatal findings were a labial fusion and a consecutive hydrometrocolpos due to a urethrovaginal fistula. <i>Method:</i> Case report of a fetus affected by an intricate cloacal anomaly. <i>Results:</i> The long-term prognosis for this nonsyndromic form of hydrometrocolpos without any other structural defects or organic failures after oper…

Investigation on phospheonol pyruvate carboxylase and proline in damaged and indamaged needles of Picea Abies and Abies Alba
1998
The client of forest damage is rapidly characterized by visible criteria such as loss and yellowing of leaves and needles Additionally damage to Norway spruce (Picea abies) and silver fit (Abies alba) can be diagnosed by biochemical criteria. The results in the present study performed in 1993 and 1994 on six Norway Spruces of each of the eleven open air stands in south-western Germany indicate that the activity of phosphoenol pyruvate carboxylase (PEPC) correlates with the extent of damage and of the loss of needles, respectively. Needles of severely damaged trees had higher levels of PEPC than needles of healthy trees. There was also a positive correlation between the activity of PEPC and …
Potere, consenso e dissenso nell’Ystoriola Langobardorum Beneventum degentium di Erchemperto
2021
Diversamente da quella narrata da Paolo Diacono nella «Historia Langobardorum», la storia dei Longobardi di Benevento fra l’VIII e il IX secolo, raccontata da Erchemperto nell’«Ystoriola Langobardorum Beneventum degentium», è una storia nella quale si alternano continuamente il bene e il male, Dio e Satana, il coraggio, la virtù, l’abnegazione da un lato e, dall’altro, la viltà, il tradimento, la perfidia. Personaggi positivi e personaggi negativi – insieme alle vicende delle quali, di volta in volta, essi sono protagonisti – si susseguono nell’«Ystoriola» a ritmo incalzante, e lo storico beneventano, talora in modo palese e scoperto, più spesso in maniera ellittica e sottintesa, manifesta …
Multi-directional vs. mono-directional multi-step strategies for single point incremental forming of non-axisymmetric components
2020
Abstract Multi Stage approach is used in Single Point Incremental Forming (SPIF) to overcome one of the main forming limitations, namely the maximum wall angle, characterizing the single stage process. In this paper, different multi-path strategies for the production of parts with flat edges are considered in order to evaluate the best solution in terms of feasibility and geometrical accuracy of the final part: A) mono-directional incremental draw angle; B) mono-directional incremental draw angle with increasing part side; C) Multi-directional approach with non-horizontal path planes. Strain evaluation by means of CGA (Circular Grid Analysis) and defect analysis have been carried out in ord…
Colourimetric image analysis as a diagnostic tool in female genital schistosomiasis
2015
Female genital schistosomiasis (FGS) is a highly prevalent waterborne disease in some of the poorest areas of sub-Saharan Africa. Reliable and affordable diagnostics are unavailable. We explored colourimetric image analysis to identify the characteristic, yellow lesions caused by FGS. We found that the method may yield a sensitivity of 83% and a specificity of 73% in colposcopic images. The accuracy was also explored in images of simulated inferior quality, to assess the possibility of implementing such a method in simple, electronic devices. This represents the first step towards developing a safe and affordable aid in clinical diagnosis, allowing for a point-of-care approach.
