African swine fever (ASF) is a highly contagious, often fatal viral disease caused by African swine fever virus (ASFV), leading to high fever, severe hemorrhages with high lethality in domestic pigs and wild boar. In 2007, ASF was reintroduced into Europe. Since then, ASF has spread to many European and Asian countries and now becomes a major concern to the swine industry worldwide. There have been various vaccine attempts, but no commercial ASF vaccines are available so far. A key hurdle in developing a safe and efficacious ASF vaccine is the limited understanding of innate and adaptive immune responses elicited by ASFV infection. Though several promising vaccine candidates have been described, more key scientific challenges remain unsolved. Here, we provide an overview of the current knowledge in innate and adaptive immune responses elicited by ASFV infection and different kinds of vaccine candidates. Additionally, the applications and prospects of vaccine candidates are discussed. Finally, we highlight the implications of these mechanisms for rational design of ASF vaccines.

Stereo-electroencephalography (SEEG) implantation before epilepsy surgery is critical for precise localization and complete resection of the seizure onset zone (SOZ). Combined metabolic and morphological imaging using hybrid PET/MRI may provide supportive information for the optimization of the SEEG coverage of brain structures. In this study, we originally imported PET/MRI images into the SEEG positioning system to evaluate the application of PET/MRI in guiding SEEG implantation in refractory epilepsy patients.

Forty-two patients undergoing simultaneous PET/MRI examinations were recruited. All the patients underwent SEEG implantation guided by hybrid PET/MRI and surgical resection or ablation of epileptic lesion. Surgery outcome was assessed using a modified Engel classification one year (13.60 ± 2.49 months) after surgery. Areas of SOZ were identified using hybrid PET/MRI and concordance with SEEG was evaluated. Logistic regression analysis was used to predict the presence of a favorable outcome with thrable outcome than those with inconsistent localization between modalities.The bacterial genus Salmonella includes a large group of food-borne pathogens that cause a variety of gastrointestinal or systemic diseases in hosts. Salmonella use several secretion devices to inject various effectors targeting eukaryotic hosts, or bacteria. In the past few years, considerable progress has been made towards understanding the structural features and molecular mechanisms of the secretion systems of Salmonella, particularly regarding their roles in host-pathogen interactions. Selleck PFI-6 In this review, we summarize the current advances about the main characteristics of the Salmonella secretion systems. Clarifying the roles of the secretion systems in the process of infecting various hosts will broaden our understanding of the importance of microbial interactions in maintaining human health and will provide information for developing novel therapeutic approaches.

Female genital mutilation (FGM) is a worldwide problem associated with severe health risks. In the UK, preventative public health campaigns have been developed to eradicate FGM. The aim of the present study was to elicit the views about FGM public health campaigns from the perspective of a UK Somali community.

Three focus groups and one interview were conducted with 16 community members.

Using posters and leaflets focused on UK FGM prevention, photo-elicitation was used to encourage participants to discuss the usefulness and implications for national public health messages aimed at eradicating FGM. Data were subjected to inductive thematic analysis.

Participants were positive about the aims of the campaigns presented within the research, believing such campaigns were necessary and increased awareness of FGM. However, participants felt the campaigns also carried risks of enhancing stereotypes in terms of ethnicity, gender and religion. For example, some images were perceived to suggest that FGM was only relevant to Sub-Saharan women, although it is also prevalent in other populations. Some fathers reported feeling unfairly targeted in campaigns that focused on the role of mothers in protecting daughters from FGM. Participants were also concerned that some poster images may suggest that FGM was associated with Islam and perceived as a religious issue, rather than a cultural one. Fears were identified that this could lead to stigmatisation and hostility towards those affected.

The research findings suggested that actively working with affected communities to develop messaging that counters negative stereotyping and associated hostility should be a priority.

Orthodontic fixed appliance therapy involves alignment of teeth through the bracket and archwires. The archwire twist (torque) imparts significant forces inside the bracket slot in refining the teeth position at the end of treatment. The objective of this in- silico study was to evaluate the torque induced bracket slot deformation in the commonly used 0.018 inch (") and 0.022" conventional Stainless Steel (SS) brackets with clinically relevant archwires during various angles of twist.

SS maxillary central incisor brackets of 0.018" width×0.022" depth (0.457 mm×0.558 mm) and 0.022" width×0.028" depth (0.558 mm×0.711 mm) were used. The SS archwires of 0.016" width×0.022" depth (0.406 mm×0.558 mm), 0.017" width×0.025" depth (0.431 mm×0.635 mm), 0.019" width×0.025" depth (0.482 mm×0.635 mm) and 0.021" width×0.025" depth (0.533 mm×0.635 mm) were engaged in the respective bracket slots. The assembled bracket-archwire Finite Element (FE) models were constructed. The archwire torque, the top, middle and bottom slformation was present in both 0.018" and 0.022" brackets which increased as the angle of twist increased. The TSD were higher than the MSD and BSD in all the bracket-archwire combinations. We conclude that there is only elastic deformation of bracket slots upto 30o angle of twist and clinicians could maintain within this torque limits to avoid plastic deformation leading to improper teeth position.
