Chiron return
No full textIn astrology, the planet Chiron represents the seemingly incurable wound. In the general sense, Chiron represents nothing less than the grand wound of human existence, of incarnate being itself. In a more specific sense, Chiron represents one’s own particular and persistent suffering. In other words, the chronic vulnerabilities shaped by one’s own unique biography, especially as connected to the mother, or more precisely, as connected to a profound wounding related to the loss of the mother. Chiron has a fifty year orbit, meaning that on one’s fiftieth birthday Chiron returns to the place in the sky it occupied at the time of one’s birth. For most, the Chiron return will be a once in a lifetime event. The Chiron return is thus the perfect opportunity to revisit the origins of the seemingly incurable wound as related to the loss of the mother. Chiron Return is a memoir organized around the rape and murder of a mother. The Chiron Return of the daughter, as she approaches her fiftieth birthday, prompts a return to the scene of the crime, both metaphorical and literal, as she seeks to understand more fully the circumstances surrounding the death of her mother.M.F.A.by Dawn Cecile Wals

Audit about Medical Decision: Data Transmission Concerning Patients with Dementia Entering French Nursing Homes Does Not Confirm the Diagnosis
No full textBackground. Dementia was affecting 855.000 patients in France in 2007. Lanmeur's rural hospital population was representative of the French nursing home's population. The followup was assumed by local GPs, which is also usual care in France for nursing homes. The study looked at clinical and paraclinical data transmitted at the institutionalization time of patients suffering from dementia.
Aim. showing that admission letters did allow establishing a diagnosis of dementia for the GPs.
Method. we included all patients with dementia at the time of institutionalization between July 2000 and July 2007. We searched in the admission letters for 25 criteria extracted from the French guidelines for dementia and Alzheimer disease diagnosis (multiple cross-sectional analysis per year).
Results. 293 patients were included. The median number of diagnostic criteria present in the letters of admission is 1 (first quartile: zero, third quartile: 4, and maximum: 12).
Conclusions. the data in admission letters did not allow the diagnosis of dementia according to the French guidelines. We know that dementia is underchecked and undertreated in France according to the same guidelines. What consequences did this lack of basic data give on motivation for treatment and recurrent diagnosis process for GPs? This has to be evaluated.</jats:p
Activity of (2060) Chiron possibly caused by impacts?
No full textThe centaur 95P/(2060) Chiron is showing comet-like activity since its discovery, but the mass-loss mechanisms triggering its activity remained unexplained. Although the collision rates in the centaur region are expected to be very low, and impacts are thought not to be responsible for the mass-loss, since the recent indications that Chiron might possess a ring similar to Chariklo's, and assuming that there is debris orbiting around, the impact triggered mass-loss mechanism should not be excluded as a possible cause of its activity. From time series observations collected on Calar Alto Observatory in Spain between 2014 and 2016, we found that the photometric scatter in Chiron's data is larger than a control star's scatter, indicating a possible microactivity, possibly caused by debris falling back to Chiron's surface and lifting small clouds of material. We also present rotational light curves, and measurements of Chiron's absolute magnitudes, which are consistent with the models supporting the presumption that Chiron possesses rings. By co-adding the images acquired in 2015, we have detected an similar to 5 arcsec long tail, showing a surface brightness of 25.3 mag(V) arcsec(-2).© The Author 2018.

Emporius, or the Anatomy of an Author
No full textThe work of Emporius, in the form it has been transmitted to us, is the result of the stratification of two different sources, i.e. the Latin translation of a Greek textbook on progymnasmata and an advanced Latin rhetorical book. It implies the activity of four authors: a Greek rhetorician (5th Century AD?) who wrote a Greek textbook on progymnasmata [Emporius1]; a Latin rhetorician (6th AD?) who “translated” this textbook into Latin [Emporius2]; a Latin rhetorician who wrote a Latin textbook on rhetoric [Emporius3]; and a late-antique or early-medieval Latin compiler (7th-8th AD?) who selected, modified and combined materials coming from the latter two sources, shaping them into the actual form [Emporius4]. Three of those textual layers can reveal a good deal of information about the teaching of the preliminary exercises between Late Antiquity and early Middle Ages
A new modification of the chiron ACS assay for total prostate-specific antigen achieves equimolar response characteristics and improves the detection of prostate cancer
No full textNonequimolar-response assays for prostate-specific antigen (PSA) are criticized for overestimating total PSA in some men without prostate cancer (PCA), and underestimating total PSA in some men with PCA. We recently studied three nonequimolar-response PSA assays that had undergone modifications. While two of the studied assays achieved equimolar-response characteristics with improved areas under receiver operating characteristic (ROC) curves (AUC), the modification of the Chiron ACS PSA assay (ACS PSA2, Chiron) failed to achieve this. Recently, the ACS assay underwent another modification (ACS PSA, Bayer), which we investigated. Sera from 305 men (155 without and 150 with PCA, PSA greater than or equal to2 and less than or equal to30 mug/l, TandemE) were measured using both modifications of the ACS assay and equimolar-response reference methods (TandemR free and Tandem E, Hybritech). Molar response relative to the reference method and clinical performance (comparison of AUCs) between the previous and new ACS assay modifications were studied. The new modification of the ACS assay (ACS PSA, Bayer) achieved equimolar-response characteristics but reported lower values (average 10%) than the Tandem E assay. Compared to the previous modification (ACS PSA2, Chiron), a 3% improvement in AUC (p=0.01) was found. Using results of the redesigned equimolar-response assay (ACS PSA, Bayer), we calculated that 6 of 155 men without PCA in this sample set could be spared unnecessary biopsy compared with the previous nonequimolar-response assay (ACS PSA2, Chiron) without missing additional PCA (90% sensitivity). These data provide additional evidence for clinical advantages of equimolar-response over nonequimolar-response PSA assay formats

Female inflorescence and fruit not seen. Distribution and ecology:—the new taxon was found and collected on a phorophyte on the shore of the Castanho lake, in an igapó forest, in the municipality of Careiro Castanho, AM, Brazil. Based on personal observations, the parental species have already been observed in this place and in neighboring municipalities (e.g. Careiro da Várzea), especially along the BR 319 road. According to Petini-Benelli (2022), C. gnomus occurs in the states of Amazonas, Pará and Rondônia and C. saccatum in the entire North-Brazilian region as well as in the states of Mato Grosso and Mato Grosso do Sul. Thus, the geographical distribution of both species overlaps, including in the state of Amazonas where the new hybrid has been found. The new natural hybrid has been observed in bloom in January, a time when the parental species can flower. Based on author’s personal observations and on herbarium registers (e.g. CRIA database, 2022), we know that C. gnomus flowering generally begins in December and stops in April whereas C. saccatum is in bloom from August up to February. Consequently, the blooming times of both species overlap during at last three months (December, January and February), making possible their crossed pollination. As for the flower visitors, we already observed visit of male Eulaema bees on both parental species, which, once more, makes a genetic flux between them possible. These bees visit the flowers looking for volatile compounds (perfume) present on the lip. Etymology:—the specific epithet is given in honor to Maria Grasineide Gomes Passos, mother of the first author, orchid lover and great incentive to orchid study. Taxonomic Discussion:—the new entity shows characters intermediate between C. gnomus and C. saccatum (Figure 3), which allowed us to infer its taxonomic position as a nothospecies. As in most species within the genus it is impossible to define diagnostic vegetative features because these species practically share the same characters (Holst 1999, Walker-Larsen & Harder 2000). As for the floral morphology, especially in male flowers, we can mention various characters shared with the parental species. Flowers are not resupinate, as in C. gnomus (vs. resupinate in C. saccatum). Floral segments are elliptic-lanceolate as in C. saccatum (vs. obovate-lanceolate and linear-lanceolate in C. gnomus) (Pettini-Benelli 2022). The lip is entire and subtrilobed (vs. trilobed in C. gnomus and C. saccatum), but suborbicular as in C. saccatum, with the margin next to the apex reflexed and overall denticulate to serrate as in both parents (serrate in C. gnomus and fimbriate, laciniate or denticulate in C. saccatum). The central part of the lip is sacciform and conical with a transverse ostium as in C. saccatum and with two small protuberances on the edge next to column as in both parents, however less acute as in C. saccatum. The column shows a more rounded shape and a beak shorter and broader as in C. gnomus (vs. column narrower and oblong with a beak filiform in C. saccatum) (see Figure 4) (Lindley 1840a, Linden & Reichenbach 1870, Pessoa et al. 2015, Petini-Benelli 2017, 2022, Krahl 2020). We propose here a key to all the natural hybrids present in the Brazilian state of Amazonas (Figure 5), i.e. C. × grasineideae (C. gnomus × C. saccatum); C. × issanense Pabst (1975: 405) (C. pileatum Reichenbach (1882: 492) × C. longifolium Lindley (1839: 94)); C. × louiseae Krahl et al. (2020: 216) (C. discolor (Lindley 1835: t. 1735) Lindley (1844: Misc. 34) × C. macrocarpum Kunth (1822: 331)); C. × roseo-album (Hooker 1840: t. 3796) Lindley (1840b: 65) (C. discolor × C. longifolium); and C. × tapiriceps Reichenbach (1888: 133) (C. macrocarpum × C. pileatum) (according to Krahl et al. 2020 and Petini-Benelli 2022). It should be noted that C. × sheyllae Krahl, Cantuária & J.B.F.Silva in Cantuária et al. (2021) perhaps occurs in Amazonas but it is not confirmed. It occurs in fact in a border region between Amazonas and Pará (see Cantuária et al. 2021). We treated C. × roseo-album as a nothospecies, so disagreeing with Barbarena (2021) who treats it as an independent species. We have a large field knowledge as for the occurrence of C. × roseo-album in localities of Brazilian Amazon where C. discolor and C. longifolium are clearly sympatric species a few meters away from each other (eg. Pessoa et al. 2015). Moreover, the nothospecies clearly presents intermediate features between the parental taxa, what we already could observe in artificial crossings. In this way we agree with the opinion of Romero & Carnevalli (1989).Published as part of Krahl, Dayse Raiane Passos, Schmal, Philippe, Chiron, Guy, Silva, João Batista Fernandes Da, Krahl, Amauri Herbert & Cantuária, Patrick De Castro, 2023, Catasetum × grasineideae (Orchidaceae: Catasetinae), a new nothospecies from Brazilian Amazon and taxonomic notes for the genus, pp. 89-104 in Phytotaxa 594 (2) on pages 90-94, DOI: 10.11646/phytotaxa.594.2.1, http://zenodo.org/record/789198
