Diagnosis. – Pseudexostoma brachysoma is distinguished from P. yunnanensis by the following combination of characteristics: posterior margin of lower lip with three notches, depth of middle notch shallower than lateral ones (vs. as the same depth), length of two smaller median lobes of lower lip longer than lateral lobes (Fig. 2A) (vs. as the same length, Fig. 2C); pelvic fin i, 3–4 (vs. i, 5); base of adipose fin longer (36.1–46.0% SL vs. 28.8–39.8); caudal peduncle more slender (depth of caudal peduncle 4.2–6.9% SL and 20–33.7% in length of caudal peduncle vs. 6.4–8.3 and 32.6–42.7); premaxillary tooth band with 16-18 teeth (vs. 18–22), premaxillary tooth band divided into two and isolated (Fig. 3A) (vs. connected partially, Fig. 3C). Pseudexostoma brachysoma differs from P. longipterus in having a shorter pectoral fin, pelvic fin and caudal fin (pectoral fin 24.9–29.8% SL vs. 30.1–31.3, pelvic fin 16.1–22.9% SL vs. 23.1–24.3, caudal fin 13.6–17.9% SL vs. 18–19.6), smaller eyes and a narrower interorbital width (eye diameter 5.8–7.8% HL vs. 8.2–10, interorbital width 19.7–24.7% HL vs. 25.5–30.8). Description. – Morphometric data as in Table 1. Body moderately compressed. Dorsal profile rising evenly and somewhat steeply from tip of snout to origin of dorsal fin, then sloping gently ventrally to end of caudal peduncle. Head and abdominal region before origin of anal fin broad and flat. Body after adipose fin compressed gradually. Head depressed and broad, triangular when viewed laterally and with rounded snout when viewed from above. Eye small and ovoid, subcutaneous and located at middle of dorsal surface of head. Mouth transverse and inferior, premaxillary and mandibular tooth bands exposed when mouth closed. Teeth embedded in skin, shovel-shaped, tips exposed and arranged in irregular rows. Premaxillary tooth band divided into two, with 16–18 teeth (Fig. 3A). Anterior nostril tubular, separated from posterior nostril by nasal barbel base. Gill opening narrow, extending from one-third of last ray of pectoral fin to the first ray. Dorsal surface smooth without tubercles. Barbels in four pairs. Maxillary barbel flattened, with surrounding flap of skin and rounded tip, extending beyond pectoral fin origin, but not reaching to gill opening and far from posttemporal. Nasal barbel with small flap of thin skin fringing posterior margin and not reaching anterior margin of orbital. Post labial groove connected. Lower lip broad with three notches along posterior margin, divided into two bigger lateral lobes and two smaller median lobes. Depth of middle notch shallower than depth of lateral side notches. Two smaller median lobes of lower lip longer than lateral lobes. Inner mandibular-barbel close to midline, extending to pectoral fin origin. Outer mandibular-barbel precedes lateral inner mandibular barbel, extending to pectoral fin origin (Fig. 2A). Unbranched dorsal fin rays not ossified. Post-dorsal margin of dorsal fin concave slightly. Origin of dorsal fin located at point through anterior third of body. Adipose fin base not connected with caudal fin. Caudal fin emarginate, upper lobe smaller than lower lobe. Anal fin post-ventral margin emarginate. Distance of anal fin origin to caudal fin base shorter than to end of pelvic fin base. Origin of pelvic fin precedes vertical end of dorsal fin base. Pelvic fin margin convex slightly, not extending to anus. Pectoral fin greatly enlarged and first unbranched ray not ossified. First unbranched ray of paired fins broadened with regular striae on ventral surface. Anus and urogenital openings located at end of pelvic fin and before origin of anal fin. Lateral line midlateral and complete. Coloration. – Grey black on dorsal surface without spots or patches. Grey yellow on ventral region. Caudal fin grey black with an irregular, small, yellow patch in the middle. Fins with grey yellow around distal edge. Distribution. – Only known from the middle and lower Nujiang basin (Fig. 4). Remarks. – “Laowo”, the type locality of Pseudexostoma yunnanensis brachysoma Chu, belonged to Yunlong County of Dali Prefecture, Yunnan and now it belongs to Lushui County of Nujiang Prefecture, Yunnan. After comparing morphological characters, the results show that there are distinct differences between the topotypes of P. yunnanensis brachysoma Chu and specimens of Pseudexostoma yunnanensis yunnanensis (Tchang) in the structure of their lower lobe, shape of premaxillary tooth band, number of branched pelvic fin rays and meristic and mensural characteristics. So they should be given species status instead of subspecies status.Published as part of Zhou, Wei, Yang, Ying, Li, Xu & Li, Ming-Hui, 2007, A Review Of The Catfish Genus Pseudexostoma (Siluriformes: Sisoridae) With Description Of A New Species From The Upper Salween (Nujiang) Basin Of China, pp. 147-155 in Raffles Bulletin of Zoology 55 (1) on pages 148-150, DOI: 10.5281/zenodo.533193

No full textCR1 Knops blood group alleles are not associated with severe malaria in the Gambia
No full textThe Knops blood group antigen erythrocyte polymorphisms have been associated with reduced falciparum malaria-based in vitro rosette formation (putative malaria virulence factor). Having previously identified single-nucleotide polymorphisms (SNPs) in the human complement receptor 1 (CR1/CD35) gene underlying the Knops antithetical antigens Sl1/Sl2 and McC(a)/McC(b), we have now performed genotype comparisons to test associations between these two molecular variants and severe malaria in West African children living in the Gambia. While SNPs associated with Sl:2 and McC(b+) were equally distributed among malaria-infected children with severe malaria and control children not infected with malaria parasites, high allele frequencies for Sl 2 (0.800, 1,365/1,706) and McC(b) (0.385, 658/1706) were observed. Further, when compared to the Sl 1/McC(a) allele observed in all populations, the African Sl 2/McC(b) allele appears to have evolved as a result of positive selection (modified Nei-Gojobori test Ka-Ks/s.e.=1.77, P-valu

Impact of short term use of interdialytic 60% ethanol lock solution on tunneled silicone catheter dysfunction.
No full textInternational audienceINTRODUCTION: Ethanol lock (EL) is used to reduce catheter infections, but its impact on dialysis catheter dysfunction has not been studied. METHODS: We analyzed the rate of dialysis silicone catheter dysfunction after an interdialytic 60% EL in an open prospective controlled non crossover cohort study, with each patient being his or her own control. The study was divided into three consecutive 2-week periods: the pre- and post-intervention periods, in which interdialytic standard locks (SL) were used, and the intervention period, in which one EL was instilled during the first week, and two consecutively in the second week. We analyzed the rate of catheter dysfunction (exchange, use of fibrinolytic, reversing the lines, difficulty in instilling or withdrawing fluid) after EL or SL. RESULTS: In 30 patients, 90 EL were instilled. The rate of catheter dysfunction increased during the EL period (2 - 13%, p < 0.001), and between the two consecutive dialysis sessions before and after EL (p < 0.05). It decreased between the two consecutive dialysis sessions after EL and the following dialysis session after an SL (p < 0.05). No catheter was removed. The urea reduction ratio did not differ in dialysis after an SL and after an EL (0.77 vs. 0.73, p = 0.17). CONCLUSION: Short term EL is associated with a transient increase in catheter dysfunction, without resulting in catheter removal or decreasing dialysis efficiency
On the sheaf-theoretic SL(2, C) Casson–Lin invariant
No full textWe prove that the (τ-weighted, sheaf-theoretic) SL(2, C) Casson–Lin invariant introduced by Manolescu and the first author is generically independent of the parameter τ and additive under connected sums of knots in integral homology 3-spheres. This addresses two questions asked by Manolescu and the first author. Our arguments involve a mix of topology and algebraic geometry, and rely crucially on the fact that the SL(2, C) Casson–Lin invariant admits an alternative interpretation via the theory of Behrend functions.</p
Candidatus Rhetoricae (or Novus Candidatus).
No full textThis little book is a find whatever it finally turns out to be! For now it seems to be a Jesuit collegium text in rhetoric following the Progymnasmata of Aphthonius. If one works from the back of the book, there is an apparently independent 48-page work, Angelus Pacis by Nicolas Caussini (Latinized name), S.J. The rest of the book seems to be a commentary on or presentation of Aphthonius' Progymnasmata in 3 parts covering 435 pages, followed by a T of C and an AI, which is often one page off. Pars II is titled Rhetoricae Praecepta, Pars III De Panegyrico seu Laudatione. Pars I seems to be Apparatus ad Fabulam et Narrationem. Fable is handled on 15-31. After the famous Greek definition of Theion done into Latin ( sermo falsus veritatem effingens ), the author distinguishes rational (human) and moral (animal) fables, with mixed fables including both. He holds (19) that the sense of the fable generally needs to be expressed; otherwise people often miss the point of a fable. His Latin for promythium is praefabulatio, for epimythium affabulatio. Apologus and parabola are identical for him with fabula. After describing the qualities and uses of fables, the author presents some nine fables that exemplify various levels of style, twice telling the same stories on two levels (WL and FC). The last example is of the florid style: The Silkworm and the Spider takes four pages to tell! I found this book sitting in a box of disparate, unmarked, old books. It pays to look!This is a hardbound book (hard cover)Language note: Bilingual: Greek/LatinElzevers
Searches for New Physics effects in b →sl-sl+ transitions
No full textThe dissertation aims at presenting the current situation in the measurements of electroweak
penguin diagrams dominated decays: b → sl−l+1 . These decays have been a smoking gun
for hunting for New Physics effects over many years, but in the last three years the research
on these phenomena has intensified due to new measurements. Enormous progress has
been made both on the theoretical and the experimental sides to understand the measured
deviations from the current Standard Model predictions, referred to in what follows as
“anomalies”. The author of this dissertation has been one of the main authors of the angular analysis
of B0→ K∗ 0µ+µ− decay in the LHCb experiment, which has been widely regarded as one
of the most important results of the flavour physics sector in recent years. He has proposed
a method called “the method of moments” to measure the angular terms of this decay,
which he has later successfully applied in the measurement itself. Moreover, he has been
the driving force behind the two other important analyses in LHCb: the measurement of
the angular distribution and branching ratio of the B0→ K∗ 0 (1430)µ+µ− decay, where again the method of moments has been used to obtain the angular coefficients, and the search for the light scalar particle that can be produced in the b → s transitions and that decays to a dimuon pair. In this case no signal has been observed and the upper limits on the branching fraction have been set, later to be used for constraining the inflaton model.
The dissertation is organized as follows: the brief introduction is followed by, the second
chapter devoted to a theoretical description of rare B decays, where the effective field
theory formalism is introduced. Furthermore, the author discusses the current theoretical
problems in calculating the Standard Model predictions for the b → sl−l+ processes. Last but not least, the optimised angular observables that are less dependent on the form
factors uncertainness are derived. The third chapter describes the experimental apparatus
used in the b → sl−l+ measurements. Special focus is put on the sub-detectors that play
an important role in the studies of b → sl−l+ transitions. Chapters 4, 5, 6 are devoted to
describing the data analyses performed by the author in the LHCb experiment. In Chapter 7
the global analysis of electroweak penguin decays is presented. This kind of global analysis
has become extremely popular in the past few years as it helps to constrain and pin down those New Physics models that are likely to be responsible for the observed anomalies. The
author of this monograph is involved in one of the biggest collaborations performing New
Physics fits, where he is the convenor of the Flavour Working group. Furthermore, the
author presents his own study on separating the long distance effects in the B0→ K∗ 0µ+µ−decay. This is the state of the art way of determining those contributions. The chapter ends with a description of possible New Physics models that can explain the observed discrepancies
