Optical coherence tomography fast versus regular macular thickness mapping in diabetic retinopathy
Objective: The purpose of the study was to investigate if absolute values and reproducibility of thickness maps obtained from 2 optical coherence tomography (OCT) scanning protocols, regular high-resolution and fast low-density mode, differ in patients with diabetic macular edema. Methods: A total of 26 consecutive patients undergoing fluorescein angiography and Stratus OCT scanning for the evaluation of diabetic macular edema at the Departments of Ophthalmology in Munich and Vienna were included. Results: Retinal thickness of the central field of the thickness map measured by fast retinal thickness protocol was 287 +/- 97 and 290 +/- 113 mu m by the regular protocol. This difference as well as that for all other fields was not statistically significant. Three times repeated measurements applying both OCT scanning modes in 10 patients yielded very good intrasession correlation coefficients between 0.70 and 0.99, with corresponding intrasession standard deviations ranging between 6 and 16 mu m. The fast mode yielded slightly less reproducible values than the regular mode. Visual acuity did not influence the results. Conclusion: In practice both scanning modes caninterchanged and absolute values can be compared directly. Best reproducibility is obtained with higher sampling density even in patients with reduced visual acuity due to diabetic macular edema. Copyright (C) 2008 S. Karger AG, Basel
Dealloying of liquid CuAu nanoclusters during rotary motion: A molecular dynamics study
Dealloying effects caused by centrifugal forces in rotating multicomponent liquid clusters are investigated with the help of classical molecular dynamics computer simulations. The model system, CuAu, is chosen to investigate the phenomenon as a function of composition and cluster size. In addition to well-established surface energy related effects, we find an enrichment of Au on the surface due to centrifugal forces, which forms a bulge surrounding the rotating cluster. Fluctuations occurring during rotation are found to counteract the dealloying effects by mixing the constituents, leading to a stationary state in the system

Sôbre uma modificação no método de Neubauer
O presente trabalho relata os dados obtidos, segundo uma modificação do método de Neubauer, comparados aos obtidos pelo método usual do citado autor. A modificação consistiu no uso de cristalizadores menores e no emprêgo de um número de plantas e de um pêso de terra muito menores. Assim, foram colocadas 25 sementes de arroz em 20 g de terra, intimamente misturadas com 40 g de areia de praia lavada, em cristalizadores de 80 mm de diâmetro, por 20 mm de altura. Decorridos 18 dias após a germinação, as plantas foram colhidas, incineradas e o potássio foi determinado por fotômetro de chama. Os resultados foram comparados com os dados obtidos através de um experimento feito com as mesmas amostras de terra e no mesmo tempo, conforme a técnica usual de Neubauer. Praticamente, os dois métodos se equivalem, conforme mostram os dados do quadro 1 em Resultados e Discussão. As principais vantagens do método modificado, em relação ao método usual de Neubauer, podem ser resumidas nas seguintes: redução do pêso da amostra de 100 para 20 g e redução do pêso da areia de praia lavada de 350 para 70 g; redução da área ocupada pelos cristalizadores para menos de um terço; redução do número de plantas para um quarto (de 100 para 25 plantas) e redução do trabalho exigido para a execução do método, desde o preparo dos cristalizadores, até o preparo das plantas, incineração e análise.A MODIFICATION OF THE NEUBAUER\u27S METHOD This paper reports the data obtained, from a modification of the Neubauer method, as compared to the data obtained from the original one. The modification consistec of using smaller crystallizing dishes, and both a very small number of seedling and weight of soil. Thus, there were seeded 25 rice grains in 20 g of soil, very well mixed with 40 g of beach washed sand, in crystallizing dishes having 8C mm in diameter and 20 mm in height. Eighteen days after germination, the seedling were pulled out, their roots washed dried, ashed and its potassium determined by the flame photometer method. The results were compared with the data obtained from an experiment carried on with the same soil samples, at the same time, according to the usual Neubauer technique. Both methods are practically equivalent, as can be seen from the data on Table I in Results and Conclusions, in the Portuguese text. The main advantages of the modified method over the usual Neubauer method may be summarized as follows: reduction of both the soil sample weight from 100 to 20 g and the washed sand from 350 g to 70 g; the room taken by the crystallizing dishes is less than one third; the number of seedlings is reduced to one forth (from 100 to 25) and it takes less work for the handling of the experiment in all its steps

Kantor & Sysoev (2006: 99) stated that in ZIN no identified material of this species is found. We detected a lot in the ZIN collection of Starobogatov with six specimens and determined as “ Caspia derzhavini ”. Since this material is a single lot that was labelled by Starobogatov himself it is very likely the type material. Type locality. Caspian Sea, probably near Cheleken Peninsula (Table 1, locality 21). Other material. None. Remarks. The shells of this species have a very slender elongate shape, and the protoconch ornamentation differs largely of that found in Caspiinae, showing irregular spiral threads on a smooth surface. Shape and protoconch features strongly remind of Laevicaspia (Neubauer et al. 2018). The small size and the short shell with only about five whorls suggest L. derzhavini is a juvenile Laevicaspia, and it might well be a synonym of a previously described Laevicaspia species. This problem cannot be properly solved from the material available for the species, which is why we consider L. derzhavini as a nomen dubium. Distribution. Middle and South Caspian Sea, 45–81 m (Logvinenko & Starobogatov 1969). Tarasov (1996b) mentioned the species from 311– 870 m.Published as part of Anistratenko, Vitaliy V., Neubauer, Thomas A., Anistratenko, Olga Yu., Kijashko, Pavel V. & Wesselingh, Frank P., 2021, A revision of the Pontocaspian gastropods of the subfamily Caspiinae (Caenogastropoda: Hydrobiidae), pp. 151-197 in Zootaxa 4933 (2) on page 186, DOI: 10.11646/zootaxa.4933.2.1, http://zenodo.org/record/455014
Terrestrial and lacustrine gastropods from the Priabonian (upper Eocene) of the Sultanate of Oman
International audienceTerrestrial and aquatic gastropods from the upper Eocene (Priabonian) Zalumah Formation in the Salalah region of the Sultanate of Oman are described. The assemblages reflect the composition of the continental mollusc fauna of the Palaeogene of Arabia, which, at that time, formed parts of the southeastern Tethys coast. Several similarities with European faunas are observed at the family level, but are rarer at the genus level. These similarities point to an Eocene (Priabonian) rather than to a Rupelian age, although the latter correlation cannot be entirely excluded. At the species level, the Omani assemblages lack any relations to coeval faunas. This suggests the possible presence of a distinct biogeographic province during the Palaeogene or may simply reflect the extremely sparse non-marine fossil record of the Eocene in the Tethys region. The occurrence of the genera Lanistes, Pila, and Gulella along with some pomatiids, probably related to extant genera, suggests that the modern African–Arabian continental faunas can be partly traced back to Eocene times and reflect very old autochthonous developments. In contrast, the diverse Vidaliellidae went extinct, and the morphologically comparable Neogene Achatinidae may have occupied the equivalent niches in extant environments.

Holotype: RGM 1309839: 1.81 x 1.80 mm (shell height x width; Fig. 4b, c, h). Paratypes: RGM 1309840: 1.52 x 1.44 mm (Fig. 4a, d, g); LV 201509 (MSU): 1.54 x 1.55 mm (Fig. 4e, f, i). Type locality. Selitrennoye, Astrakhan region, Russia (Table 1, locality 1); northern Caspian Basin; GPS coordinates: 47°10’21.19”N, 47°26’25.41”E (WGS84). Age. Hyrcanian, early Late Pleistocene, c. 107 ± 7 ka (van de Velde et al. 2020). Other material. 36 specimens (RGM 1310206). Etymology. Referring to the supposed position as predecessor to modern Andrusovia. The name is a noun in apposition. Diagnosis. Low trochiform, conical, comparably large Andrusovia with up to four well rounded whorls, wide umbilicus, broadly ovoid aperture, weakly sinuate and weakly thickened peristome. Description (emended from Neubauer et al. 2018). Shell broad trochiform, about as high as wide, with up to 4 whorls. Rarely, specimens with slightly elevated spire occur. Protoconch high domical, about semi-circular in profile; initial part immersed; consists of 1.1 whorls, measuring 300 μm in diameter; nucleus about 90 μm wide; protoconch surface finely but strongly malleate near lower suture, rest appears eroded; P/T boundary sharp, marked by massive growth constrictions near lower suture. Teleoconch whorls highly convex, with maximum convexity in adapical half, producing slightly stepped spire. Last whorl attains 74–81% of shell height. Aperture broadly ovoid, slightly inclined, with faint concavity at contact to penultimate whorl. Peristome slightly thickened and expanded at columella and base; sinuate in lateral view, with weakly protruding central part and weak adapical indentation. Umbilicus wide, deep. Fine prosocyrt growth lines cover shell. On one specimen, traces of spiral threads occur on base. Remarks. Neubauer et al. (2018) wrongfully attributed this species to the extant Andrusovia brusinai, which is here considered a junior synonym of Andrusovia dybowskii (see above). Andrusovia antecessor sp. nov. differs from that species in the larger size, the more whorls while having an equally small (compared to subfossil shells) or smaller (relative to recent shells) protoconch, the more regular coiling resulting in a perfectly conical shape, and the rounded whorls. The overall similarity (and the lack of other known species) suggests that both species are closely related; given the age, A. antecessor sp. nov. might be a phylogenetic predecessor of A. dybowskii. The smaller protoconch (and thus smaller hatching size) combined with a larger adult size of Andrusovia antecessor sp. nov. compared to modern A. dybowskii suggests a faster growth rate or, alternatively, a longer lifetime. Growth rates in gastropods typically correlate positively with temperature (e.g. Kevrekidis & Wilke 2005; Shanahan et al. 2005; McCreesh et al. 2014). Similarly, the time of hatching can occur earlier under warmer conditions (Cancino et al. 2003). The scenario of an increased growth rate in A. antecessor sp. nov. as a function of temperature fits well to the supposed warmer climate during the Hyrcanian (Yanina 2014; Krijgsman et al. 2019). Distribution. Endemic to the Caspian Sea, known only from the Late Pleistocene strata of the type locality. Reconstructions of the paleoecology suggest a shallow (15–25 m), lower mesohaline (5–8 psu) open lake environment (van de Velde et al. 2020).Published as part of Anistratenko, Vitaliy V., Neubauer, Thomas A., Anistratenko, Olga Yu., Kijashko, Pavel V. & Wesselingh, Frank P., 2021, A revision of the Pontocaspian gastropods of the subfamily Caspiinae (Caenogastropoda: Hydrobiidae), pp. 151-197 in Zootaxa 4933 (2) on pages 162-163, DOI: 10.11646/zootaxa.4933.2.1, http://zenodo.org/record/455014
