Current divergent selection may promote floral trait differentiation among conspecific populations in flowering plants. However, whether this applies to complex traits such as colour or scents has been little studied, even though these traits often vary within species. In this study, we compared floral colour and odour as well as selective pressures imposed upon these traits among seven populations belonging to three subspecies of the widespread, generalist orchid Anacamptis coriophora. Colour was characterised using calibrated photographs and scents were sampled using dynamic headspace extraction and analysed using gas chromatography-mass spectrometry. We then quantified phenotypic selection exerted on these traits by regressing fruit set values on floral trait values. We showed that the three studied subspecies were characterised by different floral colour and odour, with one of the two predominant floral volatiles emitted by each subspecies being taxon-specific. Plant size was positively correlated with fruit set in most populations, while we found no apparent link between floral colour and female reproductive success. We detected positive selection on several taxon-specific compounds in A. coriophora subsp. fragrans, whereas no selection was found on floral volatiles of A. coriophora subsp. coriophora and A. coriophora subsp. martrinii. This study is one of the first to document variation in phenotypic selection exerted on floral scents among conspecific populations. Our results suggest that selection could contribute to ongoing chemical divergence among A. coriophora subspecies.Gangs pose an extreme threat to at-risk individuals and disenfranchised communities. A unique insight into the gang life and a changing life narrative among former gang members may be assets in educating communities about systemic factors perpetuating gang activity. This grounded theory analysis examines motivations for joining and leaving gangs among 28 former gang members (age, M = 44; 87.5% male; 56.3% Hispanic or Latino) and explores motivations to improve societal outcomes via prosocial advocacy to end gang involvement. Narratives suggest a social-ecological system marked by adversity can inform motivations for joining and leaving gangs, and the potential of repurposing one's life into a social change agent. Findings indicate the changing perspective of former gang members can aid in deterring gang involvement if provided a platform to share their negative experiences of gang life and regrets for their actions in their communities to instigate societal change.After its first description in Wuhan (China), SARS-CoV-2 the agent of coronavirus disease 2019 (COVID-19) rapidly spread worldwide. Previous studies suggested that pets could be susceptible to SARS-CoV-2. Here, we investigated the putative infection by SARS-CoV-2 in 22 cats and 11 dogs from owners previously infected or suspected of being infected by SARS-CoV-2. For each animal, rectal, nasopharyngeal swabs and serum were taken. Swabs were submitted to RT-qPCR assays targeting 2 genes of SARS-CoV-2. All dogs were tested SARS-CoV-2 negative. One cat was tested positive by RT-qPCR on rectal swab. Z-VAD-FMK Nasopharyngeal swabs from this animal were tested negative. This cat showed mild respiratory and digestive signs. Serological analysis confirms the presence of antibodies against the SARS-CoV-2 in both serum samples taken 10 days apart. Genome sequence analysis revealed that the cat SARS-CoV-2 belongs to the phylogenetic clade A2a like most of the French human SARS-CoV-2. This study reports for the first time the natural infection of a cat in France (near Paris) probably through their owners. There is currently no evidence that cats can spread COVID-19 and owners should not abandon their pets or compromise their welfare.Background A wide range of fillers are already available for facial rejuvenation. Most of them are based on the use of reticulated or nonreticulated hyaluronic acid. Aims The main objective of this study is to present the advantages, efficacy, and safety profile of a new agarose gel filler without reticulating agents, for different facial areas. Patient/methods A total of 41 patients were treated with different concentrations of the agarose gel filler (1%; 1,5%; 2,5% and 3,5%). Mean age of the participants was 44.62 years. 67.7% (31/41) of the patients were female. Typically, each anatomic area was injected with half of the syringe volume (0.7 + 0.1 mL of lidocaine 2%) per side. One week after one-session treatment, Global Aesthetic Improvement Scale (GAIS) was obtained and satisfaction surveys were filled by patients. Results Clinical improvement was noted immediately, with no progressive volume gain over following days. In the GAIS, 90% of the cases scored as "significant or great improvement." Patient satisfaction was very high with 83% of them evaluating the results as 8 or higher in a scale 1-10. Only one late-onset nodule was observed some weeks after injection, that resolved completely with corticosteroid injection. Conclusions This new agarose gel filler represents an effective and safe alternative for facial rejuvenation with fillers. Among its advantages, it can be highlighted the absence of reticulating agents and its nonhydrophilic nature.Covid-19 pandemic is deeply affecting transplant activity worldwide. It is unclear whether solid organ transplant recipients are at increased risk of developing severe complications and how they should be managed, also concerning immunosuppression. This is a report about the course and management of SARS-CoV-2 infection in liver transplant recipients from a single center in Northwestern Italy in the period March-April 2020. Three patients who were treated at our institution are reported in detail, whereas summary data are provided for those managed at peripheral Hospitals. Presentation varied from asymptomatic to rapidly progressive respiratory failure due to bilateral interstitial pneumonia. Accordingly, treatment and changes to immunosuppression were adapted to the severity of the disease. Overall mortality was 20%, whereas Covid-related mortality was 10%. Two cases of prolonged (>2 months) viral carriage were observed in two asymptomatic patients who contracted the infection in the early course after transplant.
