Human umbilical cord expresses several vasoactive peptides involved in the local regulation of vascular tone: protein and gene expression of Orphanin…
2011
Full-term human umbilical cord contains three blood vessels: two arteries coiled around a vein and surrounded by Wharton’s jelly, a mucous tissue with few mesenchymal stromal cells and abundant extracellular matrix. Umbilical vessels lack innervations, thus endothelial cells must play a role in the control of blood flow. The aim of this study was to investigate in human umbilical cord the expression of five peptides that could be involved in the regulation of vascular tone: Orphanin FQ, Oxytocin, Atrial Natriuretic Peptide (ANP), endothelial Nitric Oxide Synthase (eNOS) and inducible Nitric Oxide Synthase (iNOS). The expression of these molecules in full-term human umbilical cord …
Immunohistochemical and Biomolecular Identification of Orphanin FQ, eNOS, Atrial natriuretic Factor and Oxytocin in Rat Seminal Vesicles
2009
In previous studies performed on rodents, we detected the presence of adreno-cholinergic and peptidergic innervation in seminal vesicles and other organs of the male genital system, such as prostate and ductus deferens, in which we also investigated the expression of NOS and NADPH-diaphorase. During the present project we focused our attention on the expression of some peptides involved in local control of smooth muscle relaxation, contractility, vasodilatation and control of blood flow in rat seminal vesicles. We investigated, through immunohistochemistry and RT-PCR, the presence of four peptides: orphanin, eNOS, ANF and oxytocin. Immunohistochemistry was used to detect the presence of the…
The demos in Herodian
2021
In Herodian’s historical view the demos appears to play an important political role in critical stages of the Roman empire. The political success of an emperor depends on the popular approval in Rome or in the provincial cities, besides the support of the soldiers. The essay aims to evaluate the relationship between demos and armies, between demos and senate from Commodus to Maximinus, and to analyze the differences in this chronological period. The use of the words demos and ochlos, in Herodian’ s historical work, has different values: it reveals that the historian cannot be defined philo-popular, but shows throughout interest in the popular partecipation in civil struggles.
eNOS Activation by HDL Is Impaired in Genetic CETP Deficiency.
2014
Mutations in the CETP gene resulting in defective CETP activity have been shown to cause remarkable elevations of plasma HDL-C levels, with the accumulation in plasma of large, buoyant HDL particles enriched in apolipoprotein E. Genetic CETP deficiency thus represents a unique tool to evaluate how structural alterations of HDL impact on HDL atheroprotective functions. Aim of the present study was to assess the ability of HDL obtained from CETP-deficient subjects to protect endothelial cells from the development of endothelial dysfunction. HDL isolated from one homozygous and seven heterozygous carriers of CETP null mutations were evaluated for their ability to down-regulate cytokine-induced…
miRNA Signature and Dicer Requirement during Human Endometrial Stromal Decidualization In Vitro
2012
Decidualization is a morphological and biochemical transformation of endometrial stromal fibroblast into differentiated decidual cells, which is critical for embryo implantation and pregnancy establishment. The complex regulatory networks have been elucidated at both the transcriptome and the proteome levels, however very little is known about the post-transcriptional regulation of this process. miRNAs regulate multiple physiological pathways and their de-regulation is associated with human disorders including gynaecological conditions such as endometriosis and preeclampsia. In this study we profile the miRNAs expression throughout human endometrial stromal (hESCs) decidualization and analy…

Los Reinos Mediterraneos y la defensa de la Monarquia de Felipe III
2020
Since some decades a renewed attention to the Mediterranean area in the seventeenth century has allowed a more concrete analysis of the political and military dynamics that involved the Iberian and Italian kingdoms in the years of Philip III and Philip IV. Overcoming the idea that the "great history" had left the Mare Nostrum to affect exclusively the Atlantic front, the role of the kingdoms of the Habsburg monarchy was redefined, with the use of human and material resources, in the management of the international policy. Thus, the geostrategic function covered by each territory in the new type of conflict was highlighted: the kingdom of Granada, like that of Sicily or Naples, were involved…
High accuracy Raman measurements using the Stokes and anti-Stokes lines
1997
We show that by measuring the separation between the Stokes and anti-Stokes peaks excited by two different laser lines we obtain a very precise determination of absolute phonon energies. The method is useful for measuring small changes of these energies with strain, temperature, laser power, etc. It doubles the changes and avoids the necessity of using the reference lines in the Raman spectra. The method can be applied for the determination of phonon deformation potentials, for the characterization of strained heteroepitaxial layers, and for micro-Raman analysis of strain in silicon integrated circuits. We give examples of phonon shifts in Si, Ge, GaAs, InAs, and GaP as a function of applie…
The Role of Internal and External Stakeholders
2015
The importance attributed to stakeholder issues in contemporary higher education affairs across the globe is a reflection of the changing nature of the social pact between higher education and society, brokered via the state, with new notions of trust and accountability as well as responsiveness to societal needs and demands as key attributes. This chapter takes stock of the key findings across the BRICS as per the individual contributions presented in part III of this volume.
