BACKGROUND Anosmia was one of the main symptoms of coronavirus disease 2019(COVID-19).A psychiatric history(i.e.,depression)may be an independent contributor to the risk of COVID-19 diagnosis,and COVID-19 survivors appear to have an increased risk of neuropsychiatric sequelae(bidirectional association).AIM To compare the rate of psychiatric disorder among post-COVID patients without anosmia vs patients with persistent olfactory *** We conducted a prospective case control study from March 2020 to May *** recruited at the ENT department of Nice University Hospital had a subjective olfactory complaint(visual analogue scale)for over 6 wk and a molecular or CT-proven severe acute respiratory syndrome coronavirus 2 diagnosis confirmed by ***-COVID patients without persistent olfactory disorders were recruited at the university hospital infectiology *** medical histories were collected by a psychiatrist during the *** Thirty-four patients with post-COVID-19 olfactory complaints were included in the first group of the *** percent of the patients were female(n=17).The group’s mean age was 40.5±12.9 *** control group included 32 participants,of which 34.4%were female(n=11),and had a mean age of 61.2±12.2 *** rate of psychiatric disorder among post-COVID patients with olfactory complaints was significatively higher(41.7%)than among patients without(18.8%)(χ2=5.9,P=0.015).CONCLUSION The presence of a psychiatric history may constitute a potential risk factor for the development of long COVID due to persistent *** therefore seems important to establish reinforced health monitoring after a COVID 19 infection in at-risk *** prospective,translational,and collaborative studies are needed to extrapolate these results to the general population.

In the West,skepticism often arises when China describes its political system as-a democracy,specifically a"wholeprocess people's democracy."However,this skepticism is frequently rooted in a lack of understanding about what China means by the term,how it differs from liberal democracy,and why the Chinese Government considers it an effective system for the country.

Starting from sissotrin (1), a natural isoflavonoid isolated from Trifolium baccarinii (Fabaceae), one new semisynthetic derivative, 6-nitrobiochanin A (1b) and two known derivatives, 8-nitrobiochanin A (1a) and 2",3",4",6"-tetraacetylsissotrin (1c) have been obtained after performing nitration and acetylation reactions. Their structures were assigned after interpretation of their spectrometric (HR-ESI-MS) and spectroscopic (NMR 1D and 2D) data and by comparison with those reported in the literature. The substrate as well as the semisynthetic derivatives were evaluated for their antibacterial activities against six strains. The results reveal that they are inactive or weakly active on the strains tested with the exception of 8-nitrobiochanin A (1a) which showed moderate activity (MIC = 62.5 μg∙mL−1) on Staphylococcus aureus ATCC 43300.

The aim of this study was to optimize the geometry and the design of metallic/composite single bolted joints subjected to tension-compression loading. For this purpose, it was necessary to evaluate the stress state in each component of the bolted join. The multi-material assembly was based on the principle of double lap bolted joint. It was composed of a symmetrical balanced woven glass-epoxy composite material plate fastened to two stainless sheets using a stainless pre-stressed bolt. In order to optimize the design and the geometry of the assembly, ten configurations were proposed and studied: a classical simple bolted joint, two joints with an insert (a BigHeadR insert and a stair one) embedded in the composite, two “waved” solutions, three symmetrical configurations composed of a succession of metallic and composites layers, without a sleeve, with one and with two sleeves, and two non-symmetrical constituted of metallic and composites layers associated with a stair-insert (one with a sleeve and one without). A tridimensional Finite Element Method (FEM) was used to model each configuration mentioned above. The FE models taked into account the different materials, the effects of contact between the different sheets of the assembly and the pre-stress in the bolt. The stress state was analyzed in the composite part. The concept of stress concentration factor was used in order to evaluate the stress increase in the highly stressed regions and to compare the ten configurations studied. For this purpose, three stress concentration factors were defined: one for a monotonic loading in tension, another for a monotonic loading in compression, and the third for a tension-compression cyclic loading. The results of the FEM computations showed that the use of alternative metallic and composite layers associated with two sleeves gived low values of stress concentration factors, smaller than 1.4. In this case, there was no contact between the bolt and the composite pa
