NR1H4 rs35724 G>C variant modulates liver damage in nonalcoholic fatty liver disease
2021
Background and Aims: Farnesoid X receptor (FXR) plays a key role in bile acid and lipid homeostasis. Experimental evidence suggests that it can modulate liver damage related to nonalcoholic fatty liver disease (NAFLD). We examined the impact of the NR1H4 rs35724 G>C, encoding for FXR, on liver damage in a large cohort of patients at risk of steatohepatitis. Methods: We considered 2,660 consecutive individuals at risk of steatohepatitis with liver histology. The rs35724 G>C polymorphisms were genotyped by TaqMan assays. Gene expression was evaluated by RNASeq in a subset of patients (n = 124). Results: The NR1H4 rs35724 CC genotype, after adjusting for clinic-metabolic and genetic conf…
Mortality after in-hospital cardiac arrest in patients with COVID-19: A systematic review and meta-analysis.
2021
Abstract Aim To estimate the mortality rate, the rate of return of spontaneous circulation (ROSC) and survival with favorable neurological outcome in patients with COVID-19 after in-hospital cardiac arrest (IHCA) and attempted cardiopulmonary resuscitation (CPR). Methods PubMed, EMBASE, Web of Science, bioRxiv and medRxiv were surveyed up to 8th February 2021 for studies reporting data on mortality of patients with COVID-19 after IHCA. The primary outcome sought was mortality (in-hospital or at 30 days) after IHCA with attempted CPR. Additional outcomes were the overall rate of IHCA, the rate of non-shockable presenting rhythms, the rate of ROSC and the rate of survival with favorable neuro…
Anatomie du syndicalisme
2021
Railway workers' movements, demonstrations against the reform of the Labour Code, strikes against the new pension system... Collective action by employees regularly polarises social news in France. However, it is not limited to these media phenomena and the disruption of daily life that they cause. It primarily concerns everyday life at work, the participation of employees in the management of companies and administrations and, more broadly, in that of the social protection system. Trade unions have a key role to play in this collective action. This book analyses the evolution of these organisations as vectors of collective action: their successes and failures, their relations with employee…

The Emergence of Pastoral Authority in the French Reformed Church (c.1555-c.1572)
2021
In The Emergence of Pastoral Authority in the French Reformed Church, c.1555-c.1572, Gianmarco Braghi offre un'ampia panoramica delle questioni e delle ambiguità connesse all'attuazione dell'autorità della prima generazione di pastori riformati francesi formati a Ginevra e delle loro implicazioni per il carattere e l'identità del primo movimento riformato francese in generale, utilizzandoli come prisma per l'analisi storica della transizione dall'evangelicalismo sciolto a una nascente rete sinodale-concistoriale di congregazioni riformate sparse nel regno di Francia. In The Emergence of Pastoral Authority in the French Reformed Church, c.1555-c.1572, Gianmarco Braghi offers a broad overview…
Ketogenic diet, physical activity, and hypertension—a narrative review
2021
Several studies link cardiovascular diseases (CVD) with unhealthy lifestyles (unhealthy dietary habits, alcohol consumption, smoking, and low levels of physical activity). Therefore, the strong need for CVD prevention may be pursued through an improved control of CVD risk factors (impaired lipid and glycemic profiles, high blood pressure, and obesity), which is achievable through an overall intervention aimed to favor a healthy lifestyle. Focusing on diet, different recommendations emphasize the need to increase or avoid consumption of entire classes of food, with only partly known and only partly foreseeable consequences on the overall level of health. In recent years, the ketogenic diet (…

Trends in epidemiology: the role of denominator fluctuation in population based estimates
2021
Background Population estimates are of paramount importance for calculating occurrence and association measures although they can be affected by problems of accuracy and completeness. This study has performed a simulation of the impact of Italian population size variability on incidence rates. Methods Data have been obtained by the Italian National Institute of Statistics. For each year expected cases were calculated at increasing fixed rates (up to 1,000/100,000) and were considered constant in the “following year”, calculating statistical differences (P Results In Italy and in other regions, statistically significant higher RRs were found in 2012 vs. 2011 whereas statistically significant…
Hydraulic Design of the Center-Pivot Irrigation System for Gradually Decreasing Sprinkler Spacing
2021
Design strategies that enhance modern irrigation practices, reduce energy consumption, and improve water use efficiency and crop yields are fundamental for sustainability. Although microirrigation is currently a widely applied method, center-pivot irrigation systems have become very popular on large farms, thanks to their automation, wide-coverage, and reliability. Different design procedures have been proposed, even though some aspects have not been solved yet. This paper presents a simple design procedure for center-pivot systems using a gradually decreasing sprinkler spacing along with a pivot lateral, which makes it possible to set favorable and uniformly distributed water application r…

The method used was the review of clinical records of 590 patients with 600 deciduous molars, that visited the outpatient undergraduate dental clinics for vital pulp therapy. Statistical analysis used to determine the associations of tooth type, arch location, treatment type, and the number of carious surfaces involved in successful outcomes was logistic regres…
Comparison of frequency domain measures based on spectral decomposition for spontaneous baroreflex sensitivity assessment after Acute Myocardial Infa…
2021
Abstract The objective of this study is to present a new method to assess in the frequency domain the directed interactions between the spontaneous variability of systolic arterial pressure (SAP) and heart period (HP) from their linear model representation, and to apply it for studying the baroreflex control of arterial pressure in healthy physiological states and after acute myocardial infarction (AMI). The method is based on pole decomposition of the model transfer function and on the following evaluation of causal measures of coupling and gain from the poles associated to low frequency (0.04−0.15 Hz) oscillatory components. It is compared with traditional non-causal approaches for the sp…

Melatonin alleviates Ochratoxin A-induced liver inflammation involved intestinal microbiota homeostasis and microbiota-independent manner.
2021
Melatonin (MEL) shows an anti-inflammatory effect and regulates intestinal microbiota communities in animals and humans; Ochratoxin A (OTA) induces liver inflammation through intestinal microbiota. However, it remains to know whether MEL alleviates the liver inflammation induced by OTA. In this study, MEL reversed various adverse effects induced by OTA. MEL recovered the swarming and motility of intestinal microbiota, decreased the accumulation of lipopolysaccharide (LPS), enhanced the tight junction proteins of jejunum and cecum segments; ultimately alleviated OTA-induced liver inflammation in ducks. However, it is worth noting that MEL still had positive effects on the OTA-exposed ducks a…
Rats with elevated genetic risk for metabolic syndrome exhibit cognitive deficiencies when young
2021
Metabolic syndrome (MetS) is a known risk factor for cognitive decline. Using polygenic rat models selectively bred for high and low intrinsic exercise capacity and simultaneously modelling as low and high innate risk factor for MetS respectively, we have previously shown that adult animals with lower exercise capacity/higher MetS risk perform poorly in tasks requiring flexible cognition. However, it is not known whether these deficits in cognition are present already at young age. Also, it is unclear whether the high risk genome is related also to lower-level cognition, such as sensory gating measured as prepulse inhibition. In this study, young and adult (5-8 weeks and ∼9 months) rats sel…

Small Residues Inhibit Homo-Dimerization of the Human Carbonic Anhydrase XII Transmembrane Domain
2021
Amino acids with small side chains and motifs of small residues in a distance of four are rather abundant in human single-span transmembrane helices. While interaction of such helices appears to be common, the role of the small residues in mediating and/or stabilizing transmembrane helix oligomers remains mostly elusive. Yet, the mere existence of (small)xxx(small) motifs in transmembrane helices is frequently used to model dimeric TM helix structures. The single transmembrane helix of the human carbonic anhydrases XII contains a large number of amino acids with small side chains, and critical involvement of these small amino acids in dimerization of the transmembrane domain has been sugges…

Offshore wind turbine operations and maintenance: A state-of-the-art review
2021
Abstract Operations and maintenance of offshore wind turbines (OWTs) play an important role in the development of offshore wind farms. Compared with operations, maintenance is a critical element in the levelized cost of energy, given the practical constraints imposed by offshore operations and the relatively high costs. The effects of maintenance on the life cycle of an offshore wind farm are highly complex and uncertain. The selection of maintenance strategies influences the overall efficiency, profit margin, safety, and sustainability of offshore wind farms. For an offshore wind project, after a maintenance strategy is selected, schedule planning will be considered, which is an optimizati…
Comparative analysis of two paradigm bacteriophytochromes reveals opposite functionalities in two-component signaling
2021
Bacterial phytochrome photoreceptors usually belong to two-component signaling systems which transmit environmental stimuli to a response regulator through a histidine kinase domain. Phytochromes switch between red light-absorbing and far-red light-absorbing states. Despite exhibiting extensive structural responses during this transition, the model bacteriophytochrome from Deinococcus radiodurans (DrBphP) lacks detectable kinase activity. Here, we resolve this long-standing conundrum by comparatively analyzing the interactions and output activities of DrBphP and a bacteriophytochrome from Agrobacterium fabrum (Agp1). Whereas Agp1 acts as a conventional histidine kinase, we identify DrBphP a…

Dietary evidence from Central Asian Neanderthals: A combined isotope and plant microremains approach at Chagyrskaya Cave (Altai, Russia).
2021
Neanderthals are known primarily from their habitation of Western Eurasia, but they also populated large expanses of Northern Asia for thousands of years. Owing to a sparse archaeological record, relatively little is known about these eastern Neanderthal populations. Unlike in their western range, there are limited zooarchaeological and paleobotanical studies that inform us about the nature of their subsistence. Here, we perform a combined analysis of carbon and nitrogen stable isotopes on bone collagen and microbotanical remains in dental calculus to reconstruct the diet of eastern Neanderthals at Chagyrskaya Cave in the Altai Mountains of Southern Siberia, Russia. Stable isotopes identify…
Ai confini dell’etica: la Teoria dell’amore e del libero arbitrio
2021
Dai suoi studi dedicati alla Divina Commedia (vol. XIX/2), Romano Guardini ci propone un’analisi dell’etica dantesca, vale a dire dell’architettura di valori che Dante pose a reggere i regni dell’aldilà, e che dall’aldilà disvela il corretto ordine dell’universo e l’essenza propria della persona. A condizione dell’agire etico v’è il valore della libertà, l’umana facoltà di scelta che in vita incontra il vincolo della responsabilità: la persona libera è responsabile poiché e finché nella vita terrena decide di sé. Il senso della “Teoria dell’amore e del libero arbitrio” che Guardini scorge come nucleo dell’etica dantesca è quello di una libertà che attratta dal valore -e dai valori- ad essi …
Structure formation and properties of corundum ceramics based on metastable aluminium oxide doped with stabilized zirconium dioxide
2021
Abstract The work presents a successful example of the use of YSZ binary systems for production of composite ceramic materials based on θ-Al2O3 with improved physical and mechanical characteristics which was previously considered an unpromising material. It was first obtained result of extreme nature of dependence of physical and mechanical properties of Al2O3+YSZ on the concentration of YSZ (ZrO2–3mol% of Y2O3) additive. The sintering temperature was decreased on 250 °C (from 1800 to 1550 °C). The phase composition of powders and the structure of ceramics of the Al2O3 + YSZ system were investigated depending on the amount of YSZ dopant, the structure-properties relationship was established…

Dexamethasone Inhibits the Pro-Angiogenic Potential of Primary Human Myoblasts
2021
Tissue regeneration depends on the complex processes of angiogenesis, inflammation and wound healing. Regarding muscle tissue, glucocorticoids (GCs) inhibit pro-inflammatory signalling and angiogenesis and lead to muscle atrophy. Our hypothesis is that the synthetic GC dexamethasone (dex) impairs angiogenesis leading to muscle atrophy or inhibited muscle regeneration. Therefore, this study aims to elucidate the effect of dexamethasone on HUVECs under different conditions in mono- and co-culture with myoblasts to evaluate growth behavior and dex impact with regard to muscle atrophy and muscle regeneration. Viability assays, qPCR, immunofluorescence as well as ELISAs were performed on HUVECs,…
P–409 Comparison of the incidence of ectopic pregnancies in fresh versus frozen embryo transfers in IVF/ICSI cycles: a meta-analysis of Randomized Co…
2021
Abstract Study question Is the incidence of ectopic pregnancy (EP) increased in fresh compared with frozen embryo transfer (ET)? Summary answer The fresh ET is not associated with an increase of the incidence of EP in comparison with frozen ET. What is known already EP represents the first cause of mortality in the first trimester of pregnancy. Assisted reproductive technologies (ART) are associated with an increased EP risk. The reasons of this effect are inadequately explained and may be associated with variables patients-related as tubal diseases and ART-related as the number of embryos transferred, the depth of insertion of the catheter tip during ET and the supraphysiological estradiol…
Abstract LB061: On-target peripheral and tumor immune microenvironment modulation in patients treated with lacnotuzumab (anti-CSF1, MCS110) + spartal…
2021
Abstract Background: The CSF-1/CSF-1R (colony-stimulating factor-1) pathway plays a significant role in the tumor microenvironment via regulation of tumor-associated macrophages (TAMs). Lacnotuzumab (MCS110) is a humanized monoclonal antibody against CSF-1. Lacnotuzumab may counteract the tumor suppressive microenvironment induced by CSF-1, potentially enhancing the efficacy of PD-1 inhibition. Methods: MCS110Z2102 is a phase 1b/2 study in cancer patients with advanced malignancies treated by lacnotuzumab combined with the PD-1 inhibitor spartalizumab. Eligible patients with previously treated advanced/metastatic solid tumors received 1, 3, 5, 7.5 and 10 mg/kg intravenous doses of lacnotuzu…

Ethnobotany of the Aegadian Islands: safeguarding biocultural refugia in the Mediterranean
2021
Abstract Background The Aegadian Islands are located west of Trapani, Sicily. Once the site of bountiful tuna fisheries and fruit orchards (plums, peaches, apricots), grapevines, prickly pears, and grains, the local economy is now based on tourism, and many traditional agricultural and maritime practices have been abandoned. In this study, we aimed to evaluate the state of traditional ecological knowledge (TEK) concerning the use of wild and cultivated plants and fungi for human health, food, maritime, and agricultural purposes on the islands of Levanzo, Favignana, and Marettimo and compare present-day practices with those documented in the past. Methods In-depth semi-structured interviews …
Decoupling on the Wiener Space, Related Besov Spaces, and Applications to BSDEs
2021
We introduce a decoupling method on the Wiener space to define a wide class of anisotropic Besov spaces. The decoupling method is based on a general distributional approach and not restricted to the Wiener space. The class of Besov spaces we introduce contains the traditional isotropic Besov spaces obtained by the real interpolation method, but also new spaces that are designed to investigate backwards stochastic differential equations (BSDEs). As examples we discuss the Besov regularity (in the sense of our spaces) of forward diffusions and local times. It is shown that among our newly introduced Besov spaces there are spaces that characterize quantitative properties of directional derivat…
