Directionlets: Anisotropic Multidirectional representation with separable filtering

2006

In spite of the success of the standard wavelet transform (WT) in image processing in recent years, the efficiency of its representation is limited by the spatial isotropy of its basis functions built in the horizontal and vertical directions. One-dimensional (1-D) discontinuities in images (edges and contours) that are very important elements in visual perception, intersect too many wavelet basis functions and lead to a nonsparse representation. To efficiently capture these anisotropic geometrical structures characterized by many more than the horizontal and vertical directions, a more complex multidirectional (M-DIR) and anisotropic transform is required. We present a new lattice-based pe…

1,4 dihidropiridinski derivati povećavaju ekspresiju gena Psma3, Psmb5 i Psmc6 u glasničkoj RNA štakora

2021

The ubiquitin-proteasome system modifies different cellular and protein functions. Its dysregulation may lead to disrupted proteostasis associated with multiple pathologies and aging. Pharmacological regulation of proteasome functions is already an important part of the treatment of several diseases. 1,4-dihydropyridine (1,4-DHP) derivatives possess different pharmacological activities, including antiaging and neuroprotective. The aim of this study was to investigate the effects of several 1,4-DHP derivatives on mRNA expression levels of proteasomal genes Psma3, Psmb5, and Psmc6 in several organs of rats. Rats were treated with metcarbatone, etcarbatone, glutapyrone, styrylcarbatone, AV-153…

Comparison of different 2nd order formulations for the solution of the 2D groundwater flow problem over irregular triangular meshes

2009

Mixed and Mixed Hybrid Finite Elements (MHFE) methods have been widely used in the last decade for simulation of groundwater flow problem, petroleum reservoir problems, potential flow problems, etc. The main advantage of these methods is that, unlike the classical Galerkin approach, they guarantee local and global mass balance, as well the flux continuity between inter-element sides. The simple shape of the control volume, where the mass conservation is satisfied, makes also easier to couple this technique with a Finite Volume technique in the time splitting approach for the solution of advection-dispersion problems. In the present paper, a new MHFE formulation is proposed for the solution …

The Habitual ‘Saber + Infinitive’ in South American Spanish

2022

The present paper aims to describe both synchronic and diachronic distributions of the habitual aspectual periphrasis ‘saber + infinitive’ in the varieties of Spanish spoken in the South American continent. The data used for the present analysis come from the Corpus de Referencia del Español Actual and the Corpus del Español del Siglo XXI.

Les vagues de chaleur au Sahel : caractérisation, mécanismes, prévisibilité.

2016

The mechanisms controlling Sahelian heat wave (HW) variability are examined on the period 1979-2014 using the GSOD observational database and ERA-Interim reanalyses. HW events are analyzed through all terms of the atmospheric energy balance, showing a predominant role of incoming shortwave radiation on daily maximum temperature (Tx) and atmospheric water vapor on minimum temperature (Tn). The low-frequency warming trend, not explained by the previous terms, is thought to relate to the increase of greenhouse gases concentrations, due to anthropogenic emissions. The predictability of Sahelian HW events is assessed for lead times reaching up to 15 days. The model's skill, biases and uncertaint…

Efectos de la sobreexpresión de transportadores de cobre de alta afinidad tipo CTR en Saccharomyces cerevisiae, Arabidopsis thaliana y Oryza sativa

2019

En el presente trabajo se ha estudiado el efecto que tiene la desregulación de la entrada de Cu+ mediante la alteración y sobreexpresión de transportadores de cobre de alta afinidad, tipo Ctr en tres organismos: Saccharomyces cerevisiae, Arabidopsis thaliana y Oryza sativa. Los resultados obtenidos confirman que las homeostasis del cobre y del hierro están relacionadas, ya que la alteración de la entrada de Cu+ en las células afecta a diferentes aspectos de la percepción y el transporte de hierro. En el caso de Saccharomyces cerevisiae, se ha comprobado que la falta de control en la entrada de cobre en la cepa mutante CTR1Δ300 provoca cambios en la expresión de genes como los que codifican …

2021

El incremento de enfermedades relacionadas con alteraciones en la homeostasis de la glucosa (i.e., obesidad, diabetes, glucogenosis), ha generado un continuo interés en el consumo de la quinoa (Chenopodium quinoa) y la chía (Salvia hispanica L.). Por ello, se ha estudiado en un primer objetivo el almidón de quinoa comparado con otros almidones comerciales (patata, arroz, trigo, maíz), determinando sus propiedades térmicas y de pasta y el efecto del tratamiento hidrotérmico en sus cinéticas de liberación de glucosa, así como evaluar el efecto de añadir harina de chía desgrasada (H_Ch) en los flujos de glucosa y en la respuesta metabólica en células HepG2. Como segundo objetivo, se ha estudia…

Role of ghrelin and leptin in the regulation of carbohydrate metabolism. Part I. Ghrelin

2012

Grelina jest polipeptydem wydzielanym przez komórki wydzielnicze błony śluzowej żołądka i jelit, jądro łukowate podwzgórza, a także przez komórki epsilon (e), które znajdują się w obrębie wysp trzustkowych. Grelina odgrywa ważną rolę w utrzymywaniu homeostazy energetycznej organizmu oraz wpływa na wewnątrzwydzielniczą funkcję trzustki i metabolizm glukozy. W regulacji homeostazy glukozy grelina bierze udział poprzez modulację wydzielania isuliny, jak i wrażliwości na insulinę. Wobec różnorodnych biologicznych skutków działania greliny, obecne badania poświęca się potencjalnym możliwościom ich modyfikowania. Dużo uwagi skupiono wokół enzymu zwanego O-acylo transferazą greliny (ghrelin O-acyl…
