H-He collision-induced satellite in the Lyman alpha profile of DBA white dwarf stars

2020

The spectra of helium-dominated white dwarf stars with hydrogen in their atmosphere present a distinctive broad feature centered around 1160~\AA\/ in the blue wing of the Lyman-$\alpha$ line. It is extremely apparent in WD 1425+540 recently observed with HST COS. With new theoretical line profiles based on ab initio atomic interaction potentials we show that this feature is a signature of a collision-induced satellite due to an asymptotically forbidden transition. This quasi-molecular spectral satellite is crucial to understanding the asymmetrical shape of Lyman-$\alpha$ seen in this and other white dwarf spectra. Our previous work predicting this absorption feature was limited by molecular…

Cubic Microcontainers Improve In Situ Colonic Mucoadhesion and Absorption of Amoxicillin in Rats

2020

An increased interest in colonic drug delivery has led to a higher focus on the design of delivery devices targeting this part of the gastrointestinal tract. Microcontainers have previously facilitated an increase in oral bioavailability of drugs. The surface texture and shape of microcontainers have proven to influence the mucoadhesion ex vivo. In the present work, these findings were further investigated using an in situ closed-loop perfusion technique in the rat colon, which allowed for simultaneous evaluation of mucoadhesion of the microcontainers as well as drug absorption. Cylindrical, triangular and cubic microcontainers, with the same exterior surface area, were evaluated based on i…

Mickiewiczowska głębia "miejsca". Wertykalny charakter Soplicowa

2020

The shape of a circle, with its midpoint or centre, is one of the spatial images lying at the basis of many of the lyrical poems written by Adam Mickiewicz, including The Vision, Defend Me from Myself..., The Akkerman Steppes, Spin Love…, To Flee with My Love onto a Leaf [Leaves]... The motif of a circular shape with a clearly defined centre also appears in Master Thaddeus, and in Forefathers’ Eve. Mickiewicz the poet structures his works around the imagery of a circle and its centre to convey metaphorically what is of value to Mickiewicz the man. His ‘centric’ thinking puts the poet in the centre of an ontological, metaphysical vision of the cosmos, right in the centre, at the very core of…

Body shape trajectories and risk of breast cancer: results from the SUN ('Seguimiento Universidad De Navarra') Project.

2021

AbstractObjective:The aim of this study was to assess body shape trajectories in childhood and midlife in relation to subsequent risk of breast cancer (BC) in a Mediterranean cohort.Design:The ‘Seguimiento Universidad de Navarra’ (SUN) Project is a dynamic prospective cohort study of university graduates initiated in 1999. With a group-based modelling approach, we assessed body shape trajectories from age 5 to 40 years. Multivariable Cox regression models were used to estimate the hazard ratio (HR) for BC after the age of 40 years according to the body shape trajectory.Setting:City of Pamplona, in the North of Spain.Participants:6498 women with a mean age of 40 years (sd9).Results:We identi…

Identification and expansion of human osteosarcoma-cancer-stem cells by long-term 3-aminobenzamide treatment

2009

A novel cancer stem-like cell line (3AB-OS), expressing a number of pluripotent stem cell markers, was irreversibly selected from human osteosarcoma MG-63 cells by long-term treatment (100 days) with 3-aminobenzamide (3AB). 3AB-OS cells are a heterogeneous and stable cell population composed by three types of fibroblastoid cells, spindle-shaped, polygonal-shaped, and rounded-shaped. With respect to MG-63 cells, 3AB-OS cells are extremely smaller, possess a much greater capacity to form spheres, a stronger self-renewal ability and much higher levels of cell cycle markers which account for G1-S/G2-M phases progression. Differently from MG-63 cells, 3AB-OS cells can be reseeded unlimitedly wit…

Morphological variability of Upper Paleolithic and Mesolithic skulls from Sicily

2020

Scenarios for the dispersal of Homo sapiens in Southern Europe and in the Mediterranean basin have been uncertain, given the scarceness of osteological samples and the simplicity of the proposed archaeologically-based settlement hypotheses. According to available data, the first anatomically modern humans entered Sicily during the Late Pleistocene, coming from the Italian peninsula. A presumably small Late Epigravettian population colonised coastal sites. Later, North-Western archaeological horizons gave hospitality to a significant Mesolithic expansion. In order to verify a hypothesis of continuity in the peopling of the island, we analyzed Sicilian skulls from the Late Epigravettian site …

Holistic face processing is induced by shape and texture.

2013

There is increasing evidence that shape and texture are integral parts of face identity. However, it is less clear whether face-specific processing mechanisms are triggered by face shape alone, or if texture might play an important role. We address this question by studying mechanisms involved in holistic face processing. Face stimuli were either full-color pictures of real faces (shape and texture) or line drawings of the same faces (shape without texture). In a change detection task subjects judged whether eyes and eyebrows in two otherwise identical, sequentially presented faces were different in size or not. Afterwards, subjects had to identify the just presented face among two distrac…

Psychological and behavioural factors associated with long-term weight maintenance after a multidisciplinary treatment of uncomplicated obesity

2013

Obesity is a multifactorial syndrome and the likelihood of success of a medical nutritional treatment (MNT) over the long term is low. As psychological and behavioural factors have an important role in both pathogenesis and the treatment of obesity, these issues were investigated in individuals with obesity who reported a long-term success or a failure in terms of weight loss following a MNT. Eighty-eight individuals of an original cohort of 251 subjects were re-evaluated 10 years after a MNT with cognitive-behavioural approach for uncomplicated obesity. Fifty-three participants were classified as failure (body weight change ≥0.5 kg) and 35 as a success (10-year body weight change <0.5 kg) …

Shape change in the atlas with congenital midline non-union of its posterior arch: a morphometric geometric study.

2017

Background Context The congenital midline non-union of the posterior arch of the atlas is a developmental variant present at a frequency ranging from 0.7% to 3.9%. Most of the reported cases correspond to incidental findings during routine medical examination. In cases of posterior non-union, hypertrophy of the anterior arch and cortical bone thickening of the posterior arches have been observed and interpreted as adaptive responses of the atlas to increased mechanical stress. Purpose We sought to determine if the congenital non-union of the posterior arch results in a change in the shape of the atlas. Study Design/Setting This study is an analysis of the first cervical vertebrae from osteo…
