MAST-RT0 SOLUTION OF 3D NAVIER STOKES EQUATIONS ON UNSTRUCTURED MESHS. PRELIMINARY RESULTS IN THE LAMINAR CASE
2021
MAST-RT0 solution of 3D Navier Stokes equations in very irregular domains. Preliminary results in the laminar case
2021
A new numerical methodology to solve the 3D Navier-Stokes equations for incompressible fluids within complex boundaries and unstructured body-fitted tetrahedral mesh is presented and validated with three literature and one real-case tests. We apply a fractional time step procedure where a predictor and a corrector problem are sequentially solved. The predictor step is solved applying the MAST (Marching in Space and Time) procedure, which explicitly handles the non-linear terms in the momentum equations, allowing numerical stability for Courant number greater than one. Correction steps are solved by a Mixed Hybrid Finite Elements discretization that assumes positive distances among tetrahedr…
ADHESION AND OSTEOGENIC DIFFERENTIATION OF NON-ADHERENT PROGENITORS FROM ADIPOSE-DERIVED STEM CELLS (napASCs) OVER INTEGRA DERMAL REGENERATION TEMPLA…
2012
INTRODUCTION: Non-adherent progenitors from adipose-derived stem cells (n.a.p.ASCs) represent an upstream lineage of multipotent stem cell progenitors capable of clonal expansion and asymmetric divisions comparable to stem cell spheres observed in breast, thyroid and colon, and, as such, confirm the stemness of cells extracted from lipoaspirate. The identification of napASCs confirms the stem-cell origin of the more differentiated and commonly used adherent mesenchymal stromal cells (MSCs). NapASCs adhesion for differentiation purposes may be useful in tissue engineering. In this study we investigate the feasibility of napASCs adhesion over Integra® dermal regeneration template for cell col…

THE IMPACT OF GENDER AND GRANDPARENTING ON PSYCHOLOGICAL WELL-BEING: THE PURPOSE IN LIFE
2018
The unprecedented demographic changes due primarily to increased longevity and low fertility rates had implications for family relations, in particular for grandparent involvement with grandchildren. Grandparenting emerged as a support structure and the grandparent role became vital for many grandchildren in need of care. This paper examines the relationship between gender and caring for grandchildren on the psychological well-being of older adults. Using a sample of 652 adults 60 and older attending an educational program at the University of Valencia in Spain, we report on descriptive socio-demographic variables and examine the influence of gender and grandparenting on the participants’ p…
Transpiration and Water Use of an Irrigated Traditional Olive Grove with Sap-Flow Observations and the FAO56 Dual Crop Coefficient Approach
2021
The SIMDualKc model was applied to evaluate the crop water use and the crop coefficient (Kc) of an irrigated olive grove (Olea europaea L.) located in Sicily, Italy, using experimental data collected from two crop seasons. The model applies the FAO56 dual Kc approach to compute the actual crop evapotranspiration (ETc act) and its components, i.e., the actual tree transpiration (Tc act), obtained through the basal crop coefficient (Kcb), and soil evaporation according to an evaporation coefficient (Ke). Model calibration was performed by minimizing the difference between the predicted Tc act and the observed daily tree transpiration measured with sap flow instrumentation (TSF field) acquired…
The visceral adiposity index is associated with insulin sensitivity and IGF-I levels in adults with growth hormone deficiency
2016
The visceral adiposity index, based on anthropometric and metabolic parameters, has been shown to be related to adipose tissue function and insulin sensitivity. We aimed to evaluate the performance of the visceral adiposity index in adult patients with growth hormone deficiency. We enrolled 52 patients(mean age 51 ± 13 years) with newly diagnosed growth hormone deficiency and 50 matched healthy subjects as controls at baseline. At baseline and after 12 and 24 months of treatment we evaluated anthropometric measures, lipid profile, glucose and insulin during an oral glucose tolerance test, hemoglobin A1c, homeostasis model assessment estimate of insulin resistance, quantitative insulin sensi…
Myxoid lipoadenorna of the parathyroid gland
1980
A myxoid lipoadenoma of the parathyroid gland causing primary hyperparathyroidism is reported. The very rare and histologically unusual tumor consists of an epithelial component which is combined with a stromal component in a characteristic way. Slender, irregularly branched trabeculae which mainly consist of chief cells as well as a few oxyphil cells are found as epithelial component. The predominantly myxomatous and only focally lipomatous stromal component is interpreted as an integrated tumor component of the lipoadenoma which is derived from the parathyroid adipose tissue.
Adiponectin and Orexin-A as a Potential Immunity Link Between Adipose Tissue and Central Nervous System
2018
Adipose tissue (AT) is strongly associated with development and progression of immune disorders through adipokines secretion, such as adiponectin. This protein has beneficial energetic properties and is involved in inflammation and immunity processes. Three oligomers of circulating Adiponectin with different molecular weight are described: High (HMW), Medium (MMW) and Low (LMW). The HMW is the most biologically active oligomers. On binding to its receptors AdipoR1, AdipoR2, and T-cadherin, adiponectin acts on both innate and acquired immunity. The suppression of NF-kB activation and pro-inflammatory cytokine expression in macrophages is mediated by AdipoR1. AdipoR2 mediates polarization of …
Systematic review on spheroids from adipose‐derived stem cells: Spontaneous or artefact state?
2022
Three-dimensional (3D) cell cultures represent the spontaneous state of stem cells with specific gene and protein molecular expression that are more alike the in vivo condition. In vitro two-dimensional (2D) cell adhesion cultures are still commonly employed for various cellular studies such as movement, proliferation and differentiation phenomena; this procedure is standardized and amply used in laboratories, however their representing the original tissue has recently been subject to questioning. Cell cultures in 2D require a support/substrate (flasks, multiwells, etc.) and use of fetal bovine serum as an adjuvant that stimulates adhesion that most likely leads to cellular aging. A 3D envi…
