Neuroinflammation is a crucial mechanism in many neurological disorders. Injury to the peripheral sensory nerves leads to a neuroinflammatory response in the somatosensory pathway, from dorsal root ganglia (DRG) to the spinal cord, contributing to neuropathic pain. How the immune reaction is initiated peripherally and propagated to the spinal cord remains less clear. Here, we find that ciliary neurotrophic factor (CNTF), highly expressed in Schwann cells, mediates neuroinflammatory response through the activating signal transducer and activator of transcription 3 (STAT3) and inducing interleukin 6 (IL-6) in sensory neurons. Cntf deficiency attenuates neuroinflammation in DRG and the spinal cord with alleviated pain post-injury. Recombinant CNTF applied to the sensory nerves recapitulates neuroinflammation in the DRG and spinal cord, with consequent pain development. We delineate the CNTF-STAT3-IL-6 axis in mediating the onset and progression of the inflammatory cascade from the periphery to the spinal cord with therapeutic implications for neuropathic pain.Background Management of hundreds of analytes obtained from the molecular multiplex techniques currently available may represent a challenge for clinicians in daily clinical practice. Objectives The aim of the study was to describe a comprehensive and simple approach to assess such complex molecular results, to display relevant disease-specific signatures at a glance, and to facilitate their interpretation. Method A total of 6,332 consecutive allergic patients, categorized based on clinical symptoms reported at the time of the first visit before IgE testing, were evaluated through ImmunoCAP ISAC112®. Results and conclusions The occurrence of bronchial asthma is associated with polcalcin, serum albumin, or lipocalin reactivity. Higher risk of severe reaction to food is linked to tropomyosin or nonspecific lipid transfer protein reactivity (in the absence of plant pathogenesis-related proteins [PR-10] or profilin sensitization). We used radar graphic display to highlight, at a glance, the molecular reactivity profiles associated with relevant disease-specific patterns.Background Excessive androgenesis in the skin promotes sebaceous hyperproduction which is the onset of acne vulgaris pathogenesis. Free fatty acids and lipids accumulation in the glandular infundibulum culminates in microbiota imbalance, triggering inflammatory response and follicular hyperkeratinization. Aims The purpose of this work was to present an alternative cosmetic treatment for acne skin care, focusing on the prevention of sebaceous gland dysregulation. Methods Insulin-stimulated human sebocytes were treated with non-cytotoxic concentrations of a DTRW cosmetic formulation. After 6 days of incubation, cell lysates were collected for testosterone, 5α-reductase and dyhidrotestosterone (DHT) quantitation. In parallel, cells were stained with Oil Red O to measure sebum production. Results Human sebocytes were incubated with insulin to mimic a seborrheic microenvironment with overproduction of intracellular lipids and fatty acids. Concomitant incubation of cell cultures with DRTW was able to promote a 52.97% reduction in intracellular lipid content. The anti-androgenic properties of DRTW had been proved by the reductions of testosterone (↓59.90%), 5α reductase (↓59.34%) and DHT (↓55.98%) levels in sebocyte cultures also stimulated with insulin. Conclusion The results indicate a promising action of DRTW cosmetic formulation in preventing the development of acne lesions by mechanisms involving the modulation of cutaneous androgenesis and consequently the control of sebum overproduction, considered one of the leading cause of acne.Objectives The purpose of the present study was to estimate the trends and state of research of periprosthetic joint infection (PJI). Methods Publications on PJI published between 1998 and 2018 were searched from the Web of Science database and analyzed using bibliometrics. The Altmetric score and Research Interest score were combined to provide a weighted count. The scope of the Altmetric score includes >16 weighted composite scores from websites such as Twitter, Facebook and YouTube, whereas the Research Interest score is calculated from information derived from ResearchGate. Results A total of 3245 documents were published. The largest contribution was made by the United States (US), with the most contributive institution the Rothman Institute. The most relative articles were published by the Journal of Arthroplasty, whereas the highest citation frequency journal was Clinical Orthopaedics and Related Research. There was a positive correlation between citation counts and Research Interest scores, while the Altmetric Attention score showed a negative value for highly cited articles. Conclusions Based on the current trends of globalization, there is a rising trend in publications on PJI, with the largest annual contributions made by the US. The most influential contributors are researchers from the US and Europe. Twitter is used as a platform to communicate knowledge by most PJI researchers. More recent research will focus on the diagnosis and risk factors of PJI.Since the seventies, positron emission tomography (PET) has become an invaluable medical molecular imaging modality with an unprecedented sensitivity at the picomolar level, especially for cancer diagnosis and the monitoring of its response to therapy. More recently, its combination with X-ray computed tomography (CT) or magnetic resonance (MR) has added high precision anatomic information in fused PET/CT and PET/MR images, thus compensating for the modest intrinsic spatial resolution of PET. Nevertheless, a number of medical challenges call for further improvements in PET sensitivity. These concern in particular new treatment opportunities in the context personalized (also called precision) medicine, such as the need to dynamically track a small number of cells in cancer immunotherapy or stem cells for tissue repair procedures. A better signal-to-noise ratio (SNR) in the image would allow detecting smaller size tumours together with a better staging of the patients, thus increasing the chances of putting can11C radiopharmaceuticals. The present roadmap article toward the advent of 10 ps TOF-PET addresses the status and current/future challenges along the development of TOF-PET with the objective to reach this mythic 10 ps frontier that will open the door to real-time volume imaging virtually without tomographic inversion. The medical impact and prospects to achieve this technological revolution from the detection and image reconstruction point-of-views, together with a few perspectives beyond the TOF-PET application are discussed.Context Residency programs invest considerable time and resources in candidate interviews due to their perceived ability to reveal important social traits. However, studies examining the ability of interviews to predict resident performance have shown mixed findings, and the role that the interview plays in candidate evaluation remain unclear. This mixed methods study, conducted in an anesthesiology residency program at a large academic medical center, examines how interviews contributed to candidate assessment as well as whether the addition of behavioral questions to interviews altered their role in the evaluation process. Methods During 2018-2019 residency selection season in the Department of Anesthesiology & Critical Care at the University of Pennsylvania, independent ratings for each interviewee were collected from faculty interviewers. Consensus ratings subsequently established by committee were also collected. Committee meetings were audio-recorded and transcribed for qualitative analysis. Behavioral the interviews from providing discrete assessments of interpersonal qualities-even when behavioral questions were included. In the continued effort to perform well-rounded assessments of resident candidates, further research and reflection on the role of interviewing in evaluation is necessary.MicroRNAs are regulatory molecules that can be packaged into exosomes to modulate cellular response of recipients. While the role of exosomes during viral infection is beginning to be appreciated, the involvement of exosomal miRNAs in immunoregulation in invertebrates has not been addressed. Here, we observed that exosomes released from WSSV-injected mud crabs could suppress viral replication by inducing apoptosis of hemocytes. Besides, miR-137 and miR-7847 were found to be less packaged in mud crab exosomes during viral infection, with both miR-137 and miR-7847 shown to negatively regulate apoptosis by targeting the apoptosis-inducing factor (AIF). Our data also revealed that AIF translocated to the nucleus to induce DNA fragmentation, and could competitively bind to HSP70 to disintegrate the HSP70-Bax (Bcl-2-associated X protein) complex, thereby activating the mitochondria apoptosis pathway by freeing Bax. The present finding therefore provides a novel mechanism that underlies the crosstalk between exosomal miRNAs and apoptosis pathway in innate immune response in invertebrates.Background As the climate of medical care continually shifts, more is expected of surgical specialists than ever before. The rate of burnout amongst providers appears to be increasing, while the career longevity' of the modern physician continues to rise to meet the growing demands of our patient population. Spinal surgery is a demanding field, requiring significant amounts of mental and physical fortitude. We intend to highlight issues that cause debility in this cohort of providers. Methods This study surveyed the members of the North American Spine Society (NASS) to better ascertain the issues that plague our profession, in relation to physical and mental debility. The survey included multiple-choice questions regarding demographics, burnout, and health status, among other physical and mental health concerns. Results We achieved a 19% response rate. Eighty percent of responders highlighted physical debility, and psychological, social, and/or behavioral debility (e.g., burnout) was reported by 39% of respondents. Conclusions This study highlights the need to improve the work environment and maintain physician health. While this report sheds light on the problems affecting our colleagues, there is much work that is needed to improve on them. Often the medical philosophy is to ignore one's own personal discomfort in the quest to help patients. In an era where physician career longevity is needed, these issues must be identified and addressed.Microfluidic artificial lungs (µALs) have the potential to improve the treatment and quality of life for patients with acute or chronic lung injury. In order to realize the full potential of this technology (including as a destination therapy), the biocompatibility of these devices needs to be improved to produce long-lasting devices that are safe for patient use with minimal or no systemic anticoagulation. selleck kinase inhibitor Many studies exist which probe coagulation and thrombosis on polydimethyl siloxane (PDMS) surfaces, and many strategies have been explored to improve surface biocompatibility. As the field of µALs is young, there are few studies which investigate biocompatibility of functioning µALs; and even fewer which were performed in vivo. Here, we use both in vitro and in vivo models to investigate two strategies to improve µAL biocompatibility 1) a hydrophilic surface coating (polyethylene glycol, PEG) to prevent surface fouling, and 2) the addition of nitric oxide (NO) to the sweep gas to inhibit platelet activation locally within the µAL.
