Cicinnus magnapuncta Kaye 1901
No full text<i>Cicinnus magnapuncta</i> (Kaye, 1901) <p>(Figs. 6, 9, 10, 31)</p> <p> <b>Type locality.</b> Trinidad, Tabaquite [NHMUK, syntype examined, designated here as lectotype] <i>Perophora magnapuncta</i> Kaye, 1901: Kaye (1901); Kaye & Lamont (1927).</p> <p> <i>Cicinnus magnapuncta</i> was described and illustrated implicitly from one (but possibly more) specimens collected at Tabaquite, central Trinidad, in June 1898 by W.J. Kaye (Kaye 1901, Kaye & Lamont 1927). Kaye (1901) does not indicate the sex of the type material but his illustration and the single specimen recognized as a type in the NHMUK is female (Fig. 31). The syntype in the NHMUK lacks a collecting data label, though it does bear a label reading “Trinidad, Kaye” and the accession number 1901-72. On the reverse of the accession label, <i>Perophora magnapuncta</i> Kaye is handwritten, in a style similar to that seen for other Kaye types from 1901 in NHMUK, although different from Kaye’s characteristic writing on later types. A red edged type label is also present on the specimen, along with a genitalia preparation label (the genitalia are apparently missing because the slide only contains the terminal two abdominal segments). We therefore believe that this specimen is a syntype, and here designate it as the lectotype with the following labels: C, magnapuncta Keyes [<i>recte</i> Kaye] Type genit.pr. No 6 Mimallonidae / BMNH(E) #805414/ NHMUK010588329/ Type [red edged circular label]/ Trinidad Kaye 1901 -72 [number after 1901 unclear, 72 or 92, written on upper surface of label]; <i>Perophora magnapuncta</i> Kaye [written on lower surface of label]/ LECTOTYPE ♀ <i>Perophora magnapuncta</i> Kaye designated by St Laurent and Cock, 2017 [red handwritten label].</p> <p> <i>Cicinnus magnapuncta</i> was the only mimallonid species described from Trinidad until <i>C. trini</i> described above. Although <i>C. magnapuncta</i> seemed to be endemic to the island, a single male specimen from French Guiana in the MNHN (Fig. 9) may be this species considering the similarities in external appearance to the females and the close affinity of Trinidad Mimallonidae with those of French Guiana. However, due to the lack of males from Trinidad, it is not possible to definitively state at this time that the two populations are conspecific. Interestingly, so far only females of <i>C. magnapuncta</i> have been collected or photographed in Trinidad, thus males seem to either not be strongly attracted to light or are potentially diurnal or crepuscular whereas the females arrive late (23.51 h and 0 0.44 h) at light (K. Sookdeo pers. comm.).</p> <p> Several similar <i>Cicinnus</i> species are known from mainland South America, namely: <i>C. bactriana</i> (Butler, 1878), <i>C. callipius</i> Schaus, 1928, <i>C. candacus</i> Schaus, 1928, <i>C. gaujoni</i> (Dognin, 1922), and <i>C. marona</i> Schaus, 1905. Primary types of all species have been examined by the first author. <i>Cicinnus magnapuncta</i> is unique in having weak maculation, particularly submarginally, such that there is a complete absence of dark petiolate scales. The relatively faint postmedial lines and discal spots, as well as light brown to fawn ground coloration, also can be used to distinguish <i>C. magnapuncta</i> from other species listed previously, which are darker brown or nearly orange in the case of <i>C. marona</i>, and nearly always have stronger maculation.</p> <p> Prior to this work, <i>C. magnapuncta</i> was only known from a single location in Trinidad, therefore we report several new locations for this species, and figure actual specimens (not a painted illustration) for the first time. This species is restricted to forested areas of Trinidad, though the previously mentioned specimen from French Guiana may be this species. In addition to the lectotype collected from Tabaquite in the Central Range, <i>C. magnapuncta</i> has been found on the slopes of the Northern Range.</p> <p> <b>Material examined.</b> (1 ♂ *, 6 ♀ total) <b>TRINIDAD</b>: 2 ♀, Brasso Seco: 14.III.2015 (K.

Predictive Association of Pre-Operative Defect Areas in the Outer Retinal Layers With Visual Acuity in Macular Hole Surgery
No full textPurpose: The purpose of this study was to develop methods to model the external limiting membrane (ELM) and ellipsoid zone (EZ) within the elevated cuff surrounding a macular hole (MH) to determine if the predicted size of the defect in these layers after virtual flattening was associated with the actual postoperative defect and best corrected visual acuity (BCVA). Methods: Patients were included who had undergone successful MH surgery. The defects in the ELM and EZ after virtual flattening were modeled using in-house software. Main outcomes were postoperative defects in ELM and EZ at 2 months and BCVA at 12 months. Results: Fifty-eight patients were included. BCVA improved from 0.87 (0.31) logMAR pre-operatively to 0.26 (0.21) at 12 months (P < 0.001). For both the ELM and EZ, the predicted virtually flattened pre-operative defects were associated with the actual postoperative defects at 2 months (R-2 = 0.33, P < 0.01 and R-2 = 0.50, P < 0.01, respectively). There was a significant association of BCVA at 12 months (adjusted R-2 = 0.85) with the pre-operative modeled area of the defect in the ELM (P < 0.01) and to a lesser extent with the defect in the EZ (P < 0.01) and base of the MH (P < 0.01). Conclusions: Virtually flattening of the pre-operative defect in the ELM provides important predictive information of visual acuity. Incorporation of tools into commercially available optical coherence tomography (OCT) devices to facilitate such measurements would provide the clinician with important prognostic information. Translational Relevance: We have developed methodology that can potentially be used to predict the postoperative state of the outer retinal layers and the associated visual outcome in patients undergoing surgery for MH
EFFECT OF INVERTED INTERNAL LIMITING MEMBRANE FLAP ON CLOSURE RATE, POSTOPERATIVE VISUAL ACUITY, AND RESTORATION OF OUTER RETINAL LAYERS IN PRIMARY IDIOPATHIC MACULAR HOLE SURGERY
No full textPurpose: To investigate the role of an internal limiting membrane (ILM) flap in macular hole (MH) surgery on closure rate, visual acuity, and integrity of the outer retinal layers. Methods: Retrospective, nonrandomized interventional analysis in which 117 eyes of 117 patients were included who had undergone pars-plana vitrectomy (PPV) and gas tamponade for primary idiopathic MH >400 mu m with either conventional ILM peeling or with inverted ILM flap technique at The Royal Liverpool University Hospital between January 2016 and April 2018. Main outcome measures were closure of MH, best-corrected visual acuity (BCVA) at 3, 6, and 12 months, and restoration of external limiting membrane and ellipsoid zone (EZ) using optical coherence tomography. Results: Macular hole closure rate was significantly higher in patients with an ILM flap (67/68; 98.53%) than in those with conventional ILM peeling (43/49; 87.76%) (P= 0.02). Both groups showed significant improvements in their preoperative to postoperative BCVA at 3 months from 1.07 (0.43) logarithm of the minimum angle of resolution (logMAR) (20/235 Snellen) to 0.71 (0.34) logMAR (20/103 Snellen) (P<0.001), but there was no significant difference between the two groups (P= 0.45,P= 0.71). We found significant associations between postoperative BCVA and preoperative BCVA (P< 0.01) and the integrity of the EZ (P< 0.01). In 35 patients who had follow-up to 12 months, there was a significant improvement in BCVA between 3, 6, and 12 months from 0.73 (0.45) logMAR (20/107 Snellen) to 0.53 (0.24) logMAR (20/68 Snellen) and to 0.35 (0.18) logMAR (20/45 Snellen), respectively (P< 0.01). There was no significant difference at these time periods between the two groups (P= 0.62,P= 0.21,P= 0.31). The integrity of the EZ also improved significantly between 3, 6, and 12 months (P= 0.01), irrespective of the presence of an ILM flap (P= 0.58), but with a trend toward delay in restoration in those patients with an ILM flap. The improvement in BCVA at 12 months, taking into account the age of the patient, size and duration of the MH, presence of an ILM flap, and preoperative BCVA was dependent on the state of the EZ (P= 0.01). Conclusion: In patients undergoing primary pars-plana vitrectomy for MH >400 mu m, the presence of an inverted ILM flap was associated with a significantly higher closure rate than a conventional ILM peeling. Best-corrected visual acuity showed a strong correlation with the integrity of the EZ and both improved significantly between 3, 6, and 12 months, irrespective of the presence of an ILM flap
Compositional controls on melting and dissolving a salt into a ternary melt
No full textWe explore theoretically the controls on dissolution of salt A, in an undersaturated brine of salts A and B. We show that, as the concentration of B increases, the dissolution rate of A decreases, for brine of given temperature. We also show that there is a sharper decrease in dissolution rate with increasing concentration, for concentrations of B above a critical value, where B limits the equilibrium concentration. We explore the implications of the predictions for dissolution of KCl or NaCl, by a mixed brine of NaCl and KCl, a common reaction that may arise in dissolution of evaporites. We predict that, with mixed-composition brine, KCl crystals dissolve more rapidly than NaCl crystals, unless the (far-field) brine is nearly saturated in KCl. We also predict that the dissolution rate of these salts is largely independent of fluid temperature and is controlled by compositional diffusion
Interview with Lenny Kaye
No full textLenny Kaye has been Patti Smith’s long term guitarist, friend and collaborator, ever since they first began together in the early 1970s. He grew up between New York and New Jersey, graduating in American History from Rutgers University, where he later taught a course in the Department of American Studies on the History of American Rock, which became famous because of the large number of students who wanted to enroll in it. A very prolific writer and musician, he has produced an important number of records, as well as collaborated with numerous music magazines. He is the author of two books, Waylon Jennings: An Autobiography (1996) and You Call it Madness, The Sensuous Song of the Croon (2004). Nuggets (1972), his anthology of 60s garage music, is famous for defining the genre. This interview took place when he was visiting Spain in November 2012 with the Patti Smith Group. In it, we discussed the New York scene of the 70s, music, literature, drugs, politics, and many other things
Diffusion-controlled dissolution of a binary solid into a ternary liquid with partially molten zone formation
No full textWe build a theoretical model of equilibrium dissolution of a homogeneous, solid mixture of two salts A and B, KCl and NaCl being used as the type example, into an aqueous solution of the two salts, with diffusive transport. We find that there are two sharp dissolution fronts, separating fluid, a partially molten zone containing a single solid and mixed solid. The phase change happens almost entirely at the two sharp fronts. In equilibrium, the leading front exhibits a small amount of precipitation of NaCl, simultaneous with complete dissolution of KCl. There is a unique surface in the space of far-field fluid KCl concentration, far-field fluid NaCl concentration and solid composition, dividing conditions where NaCl is the solid in the partially molten zone, from conditions where KCl is the solid in the partially molten zone. The movement rates of the dissolution fronts decrease as the concentration of either salt in the far-field fluid is increased. The movement rates of the dissolution fronts increase as either far-field temperature is increased, but this effect is smaller than that of concentration. In most circumstances, the dissolution front for a given salt moves more slowly, the more of that salt is present in the original solid, although the mass dissolution rate is not greatly affected by the solid composition
