Molecular diagnostic of Ureaplasma urealyticum presence and tetracycline resistance in urine samples
2021
Abstract Sexually transmitted infections (STIs) are among the most common infections in Romania. Infection with Ureaplasma urelyticum is one of the major causes of STIs and can cause serious complications. Although tetracycline is the drug commonly used to treat infections caused by U. urealyticum, several studies indicate the emergence and rapid development of strains resistant to these antibiotics in the United States or Europe. Tetracycline resistance in bacteria is encoded by a number of different genetic determinants but in mycoplasmas the only tetracycline resistance determinant that has been reported is the tetM gene. Tetracycline resistance among Ureaplasma spp. is associated with t…
Ryanodine receptor- and sodium-calcium exchanger-mediated spontaneous calcium activity in immature oligodendrocytes in cultures
2019
Myelination in the central nervous system depends on interactions between axons and oligodendrocyte precursor cells (OPCs). Action potentials in an axon can be followed by release of biologically active substances, like glutamate, which can instruct OPCs to start myelination. Myelin Basic Protein (MBP) is an "executive molecule of myelin" required for the formation of compact myelin. As cells of the oligodendrocyte lineage (OLCs) are capable of producing MBP in pure oligodendrocyte cultures, i.e. without neurons, we investigated Ca2+ signaling in developing OLCs in cultures. We show that spontaneous Ca2+ transients (CTs) occur at very low frequency in both bipolar OPCs and mature oligodendr…
Iron-loaded transferrin (Tf) is detrimental whereas iron-free Tf confers protection against brain ischemia by modifying blood Tf saturation and subse…
2018
Despite transferrin being the main circulating carrier of iron in body fluids, and iron overload conditions being known to worsen stroke outcome through reactive oxygen species (ROS)-induced damage, the contribution of blood transferrin saturation (TSAT) to stroke brain damage is unknown. The objective of this study was to obtain evidence on whether TSAT determines the impact of experimental ischemic stroke on brain damage and whether iron-free transferrin (apotransferrin, ATf)-induced reduction of TSAT is neuroprotective. We found that experimental ischemic stroke promoted an early extravasation of circulating iron-loaded transferrin (holotransferrin, HTf) to the ischemic brain parenchyma.…
Pasta Supplemented with Opuntia ficus-indica Extract Improves Metabolic Parameters and Reduces Atherogenic Small Dense Low-Density Lipoproteins in Pa…
2020
Food supplementation with Opuntia ficus-indica (OFI) has been associated with a significant reduction in total cholesterol, body fat, hyperglycemia and blood pressure. Since OFI may also have antioxidant and anti-atherogenic properties, we hypothesized that its supplementation might reduce atherogenic lipoproteins, including small, dense low-density lipoproteins (sdLDL). Forty-nine patients (13 men and 36 women, mean age: 56 ±
Human Breast Milk NMR Metabolomic Profile across Specific Geographical Locations and Its Association with the Milk Microbiota
2018
The composition of human breast milk is highly variable, and it can be influenced by genetics, diet, lifestyle, and other environmental factors. This study aimed to investigate the impact of geographical location and mode of delivery on the nuclear magnetic resonance spectroscopy (NMR) metabolic profile of breast milk and its relationship with the milk microbiome. Human milk metabolic and microbiota profiles were determined using NMR and 16S rRNA gene sequencing, respectively, in 79 healthy women from Finland, Spain, South Africa, and China. Up to 68 metabolites, including amino acids, oligosaccharides, and fatty acid-associated metabolites, were identified in the milk NMR spectra. The meta…
Pain Education in Schools of Nursing: a Survey of the Italian Academic Situation.
2018
Introduction: Proper assessment of pain is imperative for the development of an effective pain management plan and is a core responsibility of nurses and healthcare professionals. This article describes the contents of Italian on-line bachelor's in nursing degree programs, with particular focus on pain management.Method: A descriptive study was made on curricula published and available on-line in Italian Nursing Schools, and the concordance with the standards set by the Consensus Curriculum on Pain for Nursing ofthe International Association for the Study of Pain (IASP, 2015) was analyzed.Results: Of all the bachelor programs published on-line, 42.6% offered programs and courses specificall…
Professionalization as Status Adaptation: The Nobility, the Bureaucracy, and the Modernization of the Legal Profession in Finland
1991
In contrast to Anglo-American lines of professional development, the central agent of professionalization in many Continental countries was the state bureaucracy. However, this article proposes that an understanding of the class structure of traditional society is also needed to explain the privileged position of lawyers. An historical study of lawyers in the 19th century, after Finland was annexed by Russia, demonstrates that the legal profession provided the nobility an important medium of adaptation to the new society. The importance of the legal profession initially to the state bureaucracy, and subsequently to the nobility, explains its social prominence and its future development. An …
The social embeddedness of hydraulic engineers in the regulation of water and infrastructure in Peru
2019
Based on ethnographic fieldwork in the Majes-Colca watershed in Peru, this article explores some of the questions posed by Wittfogel regarding the management of hydraulic infrastructure and its eff...
How to study bureaucracies ethnographically?
2019
We propose a short epistemological and methodological reflection on the challenges of doing ethnographical research on public services (‘bureaucracies’) from the inside. We start from the recognition of the double face of bureaucracy, as a form of domination and oppression as well as of protection and liberation, and all the ambivalences this dialectic entails. We argue that, in classical Malinowskian fashion, the anthropology of bureaucracy should take bureaucrat as the ‘natives’, and acknowledge their agency. This means adopting basic anthropological postures: the natives (i.e. the bureaucrats) must have good reasons for their seemingly ‘absurd’ (or arbitrary) practices, once you underst…
