Opis:
Pion interferometry (HBT) measurements relative to the reaction plane provide an estimate of the transverse source anisotropy at freeze-out, which probes the system dynamics and evolution duration. Measurements by the STAR Collaboration indicate that the source is extended increasingly out-of-plane with increasing impact parameter, suggesting a short evolution duration roughly consistent with estimates based on azimuthally-integrated HBT measurements.

Opis:
In August 1942, anthropologist Elfriede Fliethmann and psychologist Ferdinand Carspecken tried various standardized psychological tests during a field examination in the Southern Polish town of Witów. Sources suggest that subsequent studies were intended to provide a “scientific” justification for the regime’s ethnic reorganization plans, similarly to a study in the Reichsgau Wartheland by psychologist Rudolf Hippius in the same summer. By employing a comparative mode of enquiry, the case study presented here gives a rare insight into then newly established scientific field: on the interface between anthropology and psychology, the concept of Rassenpsychologie (racial psychology) aimed to close the proclaimed gap between the natural sciences and humanities. Due to its fundamental conception the field was thus predestined to serve the Nazi regime. Investigating specific research practices of the (junior) scientists involved helps us under- stand further development of the concept of race, and thus the foundation of National Socialist ideology.

Opis:
25 stycznia 2019 r., w Uniwersytecie Południowej Florydy miało miejsce uroczyste spotkanie poświęcone aktywności akademickiej Carolyn Ellis i Arthura Bochnera, którzy po ponad osiemdziesięciu pięciu latach (łącznie) pracy dydaktycznej przeszli na emeryturę. Tekst został przygotowany przez naukowych współpracowników, studentów oraz przyjaciół Profesorów Ellis i Bochnera, by upamiętnić i uhonorować Ich dzieło, i stanowi zbiór krótkich historii. Ukazuje on zarówno „oficjalne”, jak i „nieoficjalne” (w niektórych wypadkach bardzo osobiste) doświadczenia związane z życiem i pracą Profesorów. Opowieści te zapraszają czytelników do świata akademickich relacji międzypokoleniowych, uwikłanych kontekstowo i ważnych z etycznego punktu widzenia.  
On January 25th, 2019, The University of South Florida sponsored an event to honor the legacy of Carolyn Ellis and Arthur Bochner as they retire after more than 85 years (combined) teaching. In this paper, research collaborators, students, and friends present their testimonials commemorating their shared lives with Professors Ellis and Bochner. A collection of short stories reveals “official” and “non-official” (in some cases very personal) experiences as they were lived through, inviting readers to see how academic intergenerational relationships might develop as contextually situated and morally important.

Opis:
Metallic materials are indispensable for construction of surgical implants, particularly those designed for load-bearing application, such as the bone-anchoring parts of big joint replacements. For good osteointegration, long-term function, durability and also mechanical and chemical resistance of the implant, the physical and chemical properties of the material surface are of a great importance. These properties can be favorably influenced by coating the bone-anchoring parts of the implants with appropriate biocompatible and bioactive films. Therefore, in this study, we have investigated the adhesion and growth of human osteoblast-like MG 63 cells in cultures on titanium substrates coated with films made of gold microparticles and/or poly(ethylene imine) (PEI). Gold microparticles were chosen for good biocompatibility of gold and absence of its cytotoxicity, which has been proved by numerous studies performed in vitro and in vivo [1,2]. When deposited on the material surface, these microparticles provide this surface with microstructure, which has been reported to enhance the osteogenic differentiation of bone-derived cells. On the other hand, the material surface microroughness has dual effect on the cell adhesion, spreading and proliferation - some studies reported the enhancement, other the reduction of these events (for a review, see [3,4]). This suggests that not only the size of the microscale irregularities, but also their shape should be taken into account. Therefore, in our study, gold microparticles were used in the form of plates or polyhedral crystals [5]. These microparticles were deposited on square samples of Ti (1x1 cm, thickness 1 mm) and annealed with a hydrogen flame. As for PEI, this polymer has been used as precursor base layer for further functionalization of metallic substrates, particularly with polyelectrolyte multilayer films [6] or biomolecules such as gelatin, hyaluronan or chitosan [7,8]. Other reason for the PEI deposition was creation of an intermediate layer which would compensate the differences in mechanical properties (e.g., hardness, toughness, specific weight) between a metallic implant and bone tissue. PEI was deposited either on pure or on gold microparticle-coated Ti samples. The materials were sterilized with 70% ethanol (1 hour), inserted into 24-well polystyrene plates (well diameter 1.5 cm; TPP, Switzerland) and seeded with human osteoblast-like MG 63 cells (30 000 cells/well, i.e. 17 000 cells/cm2). Each well contained 1.5 ml of a medium DMEM with 10% of fetal bovine serum and 40 /jg/ml of gentamicin. On days 1, 3 and 7 after seeding, the cell number and morphology were evaluated. For evaluating the cell number, the cells were trypsinized and counted in Bürker hemocytometer. For evaluating the cell morphology, i.e. the cell shape and the size of cell spreading area, the cells were fixed with 70% ethanol (-20°C, 10 min) and stained with a combination of fluorescence dyes Texas Red C2-maleimide, which stains the cell membrane and cytoplasm, and Hoechst #33342, which stains the cell nuclei. The microphotographs of cells were taken using an Olympus IX 51 microscope equipped with a DP 70 digital camera, and the cell spreading area was measured on these pictures using a software Atlas (Tescan, Brno, Czech Rep.) One day after seeding, the highest number of initially adhered cells was found on the surface modified by gold polyhedral crystals. This trend was the same on days 3 and 7 after seeding (FIG.1,2). However, the cell number on Ti modified with gold plates was significantly lower than on Ti with polyhedral crystals. Nevertheless, the numbers of cells on Ti samples coated with gold microparticles without PEI were significantly higher than on PEI-coated samples. Also the cell spreading areas were significantly larger on the samples without PEI. The cells on the samples without PEI were mostly polygonal, while the cells on PEI-coated samples were of star-like appearance, i.e. with multiple long protrusions (FIG.2). This is in accordance with findings published by other authors, documenting cytotoxic effects of PEI, particularly that of a high molecular weight [6], which was also used in our study (m.w. 750 kDa). Nevertheless, this cytotoxicity was considerably reduced by further functionalization of PEI with biomolecules, such as gelatin, hyaluronan or chitosan [7,8]. Thus, it can be concluded that the modification of titanium plates by gold microparticles supported the adhesion and growth of MG 63 cells. In this context, the polyhedral crystals were more advantageous than plates. The effects of PEI coatings on cell behavior need further investigation.

Opis:
Metallic materials are important for load-bearing bone implants. The osteointegration of these implants can be improved by appropriate surface modifications. Therefore, we present here a study of the cell growth on titanium surfaces modified with films created from gold microparticles. These particles in the form of microplates or polyhedral microcrystals were deposited on titanium plates from ethanol solutions, dried and annealed with a hydrogen flame. Some samples were additionally modified by polyethylene imine. The materials engendered from these modifications were used to investigate the adhesion and growth of human osteoblast-like MG-63 cells on these surfaces in the DMEM medium with 10% of fetal bovine serum. One day after seeding, the highest number of initially adhered cells was found on the surfaces modified by both types of gold microparticles. This trend was the same three and seven days after seeding. The numbers of cells on pure Ti and Ti modified only with gold particles were significantly higher than on samples which were modified with polyethylene imine. The cell spreading areas projected on the materials were significantly larger in cells on the samples with polyethylene imine modification. However, the shape of these cells was mostly rounded or star-like with thin and long protrusions, while on the materials without polyethylene imine, it was mostly polygonal. The cell proliferation activity was estimated from XTT test, based on the activity of mitochondrial enzymes. This test showed that the proliferation activities of osteoblast-like MG-63 cells of the 3rd and 7th days of the experiment were more pronounced on the samples modified only by gold microparticles. Immunofluorescence showed that the focal adhesion plaques containing vinculin and the fibers containing β-actin were most apparent, more numerous and more brightly stained in cells on Ti modified by gold microplates and gold polyhedral microcrystals, especially in comparison with the corresponding samples modified with polyethylene imine (Fig. 1). Thus, it can be concluded that the modification of titanium samples by both types of gold microparticles enhanced the adhesion and growth of MG 63 cells.

Opis:
Metal surfaces have become important over the last decade for potential surgical implants, and within this context we present here a study of the cell growth on modified gold surfaces. Gold films, deposited on glass plates and annealed with a hydrogen flame, were modified with four different carboranethiol derivatives: 1-(HS)-1,2-C2B10H11 (A), 1,2-(HS)2-1,2-C2B10H10 (B), 9,12-(HS)2-1,2-C2B10H10 (C) and 1,12-(HS)2-1,12- C2B10H10 (D). The materials engendered from these modifications were used to investigate the adhesion and growth of rat aortic smooth muscle cells cultured on these surfaces in a DMEM medium with 10% of fetal bovine serum. One day after seeding, the highest number of initially adhered cells was found on the surface of a bare gold film. However, three days after seeding, the number of cells on carboranethiol-modified gold samples B, C and D was significantly higher than the number on a bare gold film. After seven days, the number of cells on a bare gold film and on gold films modified with derivatives A, B and D was very similar, but the surface of a gold film modified with derivative C exhibited a significantly smaller number of cells. This may be explained by the exposure of the CH vertices of the carborane cluster, which are more acidic than the BH vertices exposed toward the cells in either A or B.
