Redescription and resurrection of the status of Joyeuxiella gervaisi (Setti, 1895) (Eucestoda, Dipylidiidae)
No full textA study of the parasite fauna of feral cats in Dubai revealed the presence of two Joyeuxiella species, J. pasqualei (Diamare, 1893) and J. fuhrmanni (Baer, 1924). While the wide distribution of J. pasqualei includes countries of the Middle East, Africa, Asia and Europe, J. fuhrmanni was previously reported from felid hosts from southern Africa and has not been found in other cat parasite surveys in the Middle East, except from Dubai. The availability of historical references, however, raised doubts about the correctness of the allocation of the small Joyeuxiella sp. from Dubai cats to J. fuhrmanni and for this reason, a reexamination of stored material in the parasite collection of the Central Veterinary Research Laboratory in Dubai was carried out. A total of 40 specimens of the small Joyeuxiella sp. with a strobila length between 30 and 60 mm and consisting of 52 to 85 segments obtained from domestic cats and formerly allocated to J. fuhrmanni were studied. In complete specimens, 10 - 13 rows of rostellar hooks were counted. Mature segments were wider than long, round testes were concentrated posterior to coiled vasa deferentia and did not reach the anterior rim of the proglottids. Narrow cirri reached up to 520 μm in length. Gravid segments were longer than wide and egg capsules were restricted to the space between longitudinal excretory vessels. The examination revealed that the morphology of these cestodes matched the main characteristics of J. fuhrmanni. However, the little known cestode, J. gervaisi (Setti, 1895), that had been described from Genetta abyssinica imported from Eritrea 29 years earlier and was declared a species inquirenda met the same main morphological criteria. In this paper, the status of J. gervaisi as a valid species was resurrected and J. fuhrmanni was declared a junior synonym

Takotsubo cardiomyopathy: a diagnostic challenge
No full textThe frequency of the diagnosis of takotsubo cardiomyopathy has increased rapidly over the past few years, possibly due to increasing awareness among cardiologists. At initial presentation the diagnosis remains a challenge because of the close similarity between the presentation of takotsubo cardiomyopathy, and that of ST elevation myocardial infarction (STEMI). Recognition of salient aspects of the medical history at presentation are important in order to organise further appropriate investigations such as echocardiography and left ventriculography at the time of coronary angiogram. Takotsubo cardiomyopathy can be easily missed without ventriculography early after presentation because of the transient nature of left ventricular dysfunction, and in many centres left ventriculogram is not done as standard in the setting of STEMI. The authors advocate left ventriculography in all cases of ST elevation who have unobstructed coronaries. The correct diagnosis of takotsubo cardiomyopathy is very important for future advice and management of the patient. The prognosis of this condition is generally excellent with almost all patients returning to normal within a few weeks. This article examines the takotsubo cardiomyopathy literature and discusses the pathophysiology, clinical features, management, and prognosis of this condition in the context of an illustrated case

Morphologically and phylogenetically, <i>Lactarius indoevosmus</i> is close to the European species <i>Lactarius evosmus</i> (98 % identity for 98–100 % query coverage using BLAST) and <i>Lactarius zonarius</i> var. <i>riparius</i>. However, <i>Lactarius evosmus</i> can be differentiated by the pale cream to cream or pinkish buff, azonate pileus; whitish chrome to pale cream, decurrent lamellae; watery white, acrid latex; slightly smaller basidiospores (6.0‒9.2 × 4.6‒7.4 μm) with shorter (up to 0.5 μm high) ornamentation arranged in a zebra-like pattern, and scarce, never emergent pleuromacrocystidia (Hesler & Smith 1979, Heilmann-Clausen <i>et al</i>.1998). <i>Lactarius zonarius</i> var. <i>riparius</i> is also close to <i>Lactarius indoevosmus</i> but the presence of tomentose to cottony–tomentose and glabrous pileus margin, nonforked lamellae, acrid taste and slightly smaller basidiospores 7–9 × 5.5–7.5 μm in <i>Lactarius zonarius</i> var. <i>riparius</i> separates it from <i>Lactarius indoevosmus</i> (Barge and Cripps 2016). Another Indian species of <i>Lactarius</i> reported from the same locality (<i>Lactarius drassinus</i>) could be confused in the field with <i>Lactarius indoevosmus</i> but the presence of a dull white to greyish brown, faintly zonate pileus; pinkish white lamellae; smaller basidiospores (8.0–11.5 × 5.5–8.0 μm) with ornamentation composed of ridges up to 0.8 μm high and warts forming an almost complete reticulum separates <i>Lactarius drassinus</i> from <i>Lactarius indoevosmus</i> (Verma <i>et al</i>. 2021). <i>Lactarius indozonarius</i> Uniyal, K. Das & Nuytinck (2018a: 471), which was originally reported from India, differs from <i>Lactarius indoevosmus</i> by its viscid to glutinous, zonate pileus with hairy margin; scrobiculate stipe; fruity odour; subglobose to broadly ellipsoid basidiospores (7–8.5 × 6.5–7.5 µm) and association with <i>Quercus leucotrichophora</i> (Uniyal <i>et al</i>. 2018a).</p>Published as part of <i>Verma, Komal, Mehmood, Tahir, Uniyal, Priyanka & Sharma, Yash Pal, 2022, Lactarius indoevosmus and L. kanadii (Russulaceae), two new species from the northwestern Himalayas, India, inferred from morphology and molecular data, pp. 165-177 in Phytotaxa 541 (2)</i> on pages 167-172, DOI: 10.11646/phytotaxa.541.2.6, <a href="http://zenodo.org/record/6388745">http://zenodo.org/record/6388745</a>
A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Jammu and Kashmir, Kathua, Samanamanj, 1749 m, N 32º42.996ʹ E 075º25.931ʹ, 08 August 2020 K. Verma LK-021; Kathua, Garh 1700 m, 10 August 2020, K. Verma, LK-023. Notes:—Phylogenetically, Lactarius fuliginosus (98 % identity for 98–100 % query coverage using BLAST) and Lactarius picinus (98 % identity for 99–100 % query coverage using BLAST) are closest to Lactarius kanadii and these species could be confused in the field due to their similar macromorphology (basidiome shape, colors of pileus and lamellae). However, Lactarius picinus can be differentiated by its fuscous to brownish olive or sepia-coloured pileus, scant white latex which stains the lamellae salmon to reddish brown, slightly smaller, globose to broadly ellipsoid basidiospores, and its association with Picea sp. Lactarius fuliginosus, which is also close to Lactarius kanadii, can be differentiated by its velvety, greyish brown pileus, globose to broadly ellipsoid basidiospores with an almost complete reticulum, a pileipellis as a trichoepithelium, and its occurrence in coniferous and deciduous forests (Heilmann-Clausen et al. 1998, Stubbe & Verbeken 2012). Lactarius atromarginatus can be differentiated from Lactarius kanadii by its marginate lamellae, abundant watery white latex that turns pale lilac and basidiospores with ornamentation forming a complete reticulum (Verbeken & Horak 2000, Lee et al. 2018). In the context of Indian representatives of L. subg. Plinthogalus, Lactarius nodulisporus and L. singeri could be confused with Lactarius kanadii due to the dark colored basidiomes. However, Lactarius nodulisporus can be segregated from Lactarius kanadii by its white latex, adnexed, distant lamellae and presence of nodulose ornamentation on the basidiospores (Uniyal et al. 2018). Lactarius singer differs from Lactarius kanadii in having a strongly rugose pileus with white context that remains unchanged on exposure, a palisadic pileipellis, a stipitipellis as a trichoderm and occurrence with Quercus sp. and Abies sp. (Uniyal et al. 2018).Published as part of Verma, Komal, Mehmood, Tahir, Uniyal, Priyanka & Sharma, Yash Pal, 2022, Lactarius indoevosmus and L. kanadii (Russulaceae), two new species from the northwestern Himalayas, India, inferred from morphology and molecular data, pp. 165-177 in Phytotaxa 541 (2) on pages 172-175, DOI: 10.11646/phytotaxa.541.2.6, http://zenodo.org/record/638874
