Chronic stress can alter the immune system, adult hippocampal neurogenesis and induce anxiety- and depressive-like behaviour in rodents. However, previous studies have not discriminated between the effect(s) of different types of stress on these behavioural and biological outcomes. We investigated the effect(s) of repeated injection vs. permanent social isolation on behaviour, stress responsivity, immune system functioning and hippocampal neurogenesis, in young adult male mice, and found that the type of stress exposure does indeed matter. Exposure to 6 weeks of repeated injection resulted in an anxiety-like phenotype, decreased systemic inflammation (i.e., reduced plasma levels of TNFα and IL4), increased corticosterone reactivity, increased microglial activation and decreased neuronal differentiation in the dentate gyrus (DG). In contrast, exposure to 6 weeks of permanent social isolation resulted in a depressive-like phenotype, increased plasma levels of TNFα, decreased plasma levels of IL10 and VEGF, decreased corticosterone reactivity, decreased microglial cell density and increased cell density for radial glia, s100β-positive cells and mature neuroblasts-all in the DG. Interestingly, combining the two distinct stress paradigms did not have an additive effect on behavioural and biological outcomes, but resulted in yet a different phenotype, characterized by increased anxiety-like behaviour, decreased plasma levels of IL1β, IL4 and VEGF, and decreased hippocampal neuronal differentiation, without altered neuroinflammation or corticosterone reactivity. These findings demonstrate that different forms of chronic stress can differentially alter both behavioural and biological outcomes in young adult male mice, and that combining multiple stressors may not necessarily cause more severe pathological outcomes.Psoriatic arthritis (PsA) is a debilitating immune-mediated inflammatory arthritis of unknown pathogenesis commonly affecting patients with skin psoriasis. Here we use complementary single-cell approaches to study leukocytes from PsA joints. Mass cytometry demonstrates a 3-fold expansion of memory CD8 T cells in the joints of PsA patients compared to peripheral blood. Meanwhile, droplet-based and plate-based single-cell RNA sequencing of paired T cell receptor alpha and beta chain sequences show pronounced CD8 T cell clonal expansions within the joints. Transcriptome analyses find these expanded synovial CD8 T cells to express cycling, activation, tissue-homing and tissue residency markers. T cell receptor sequence comparison between patients identifies clonal convergence. Finally, chemokine receptor CXCR3 is upregulated in the expanded synovial CD8 T cells, while two CXCR3 ligands, CXCL9 and CXCL10, are elevated in PsA synovial fluid. Lazertinib Our data thus provide a quantitative molecular insight into the cellular immune landscape of psoriatic arthritis.Rare copy number variants associated with increased risk for neurodevelopmental and psychiatric disorders (referred to as ND-CNVs) are characterized by heterogeneous phenotypes thought to share a considerable degree of overlap. Altered neural integration has often been linked to psychopathology and is a candidate marker for potential convergent mechanisms through which ND-CNVs modify risk; however, the rarity of ND-CNVs means that few studies have assessed their neural correlates. Here, we used magnetoencephalography (MEG) to investigate resting-state oscillatory connectivity in a cohort of 42 adults with ND-CNVs, including deletions or duplications at 22q11.2, 15q11.2, 15q13.3, 16p11.2, 17q12, 1q21.1, 3q29, and 2p16.3, and 42 controls. We observed decreased connectivity between occipital, temporal, and parietal areas in participants with ND-CNVs. This pattern was common across genotypes and not exclusively characteristic of 22q11.2 deletions, which were present in a third of our cohort. Furthermore, a data-driven graph theory framework enabled us to successfully distinguish participants with ND-CNVs from unaffected controls using differences in node centrality and network segregation. Together, our results point to alterations in electrophysiological connectivity as a putative common mechanism through which genetic factors confer increased risk for neurodevelopmental and psychiatric disorders.Metre-scale plasma wakefield accelerators have imparted energy gain approaching 10 gigaelectronvolts to single nano-Coulomb electron bunches. To reach useful average currents, however, the enormous energy density that the driver deposits into the wake must be removed efficiently between shots. Yet mechanisms by which wakes dissipate their energy into surrounding plasma remain poorly understood. Here, we report picosecond-time-resolved, grazing-angle optical shadowgraphic measurements and large-scale particle-in-cell simulations of ion channels emerging from broken wakes that electron bunches from the SLAC linac generate in tenuous lithium plasma. Measurements show the channel boundary expands radially at 1 million metres-per-second for over a nanosecond. Simulations show that ions and electrons that the original wake propels outward, carrying 90 percent of its energy, drive this expansion by impact-ionizing surrounding neutral lithium. The results provide a basis for understanding global thermodynamics of multi-GeV plasma accelerators, which underlie their viability for applications demanding high average beam current.BACKGROUND A safer and more delicate approach is required for the management of a post-traumatic aphakia and subtotal aniridia. CASE REPORT A 55-year-old man was referred to our clinic with symptoms of decreased vision (hand motion) and photophobia in his right eye. This patient had previously undergone pars plana vitrectomy (PPV) for the management of blunt ocular trauma in the same eye. He was being treated with topical antihypertensives, due to silicone oil-induced glaucoma. On presentation, the best corrected visual acuity (BCVA) in his right eye was 20/40 and the intraocular pressure (IOP) in the same eye was 20 mmHg. Slit lamp examination of his right eye showed aphakia, aniridia, and some silicone oil droplets (fish eggs) following silicone oil extraction. link2 His corneal endothelium and thickness were within normal limits. Dilated fundoscopic examination of the right eye revealed that the retina was attached with no signs of proliferative vitreoretinopathy (PVR). An artificial iris intraocular lens (IOL) was implanted, along with 4-point scleral fixation in conjunction with Gore-Tex sutures. After 6 months, the BCVA in his right eye was 20/40 and he had no symptoms of photophobia. The IOP in that eye was 15 mmHg while on treatment with dorzolamide-timolol eye drops. No suture-related or other serious complications were observed. The patient expressed satisfaction with the functional and cosmetic results. CONCLUSIONS Modern vitrectomy combined with an artificial iris IOL and scleral fixation with Gore-Tex sutures in eyes lacking an iris and lens can provide long-term anatomic and functional restoration. Intraoperative IOP fluctuations and extra corneal damage can be avoided by lens preparation with the sutures using a small incision ab-externo approach.BACKGROUND Early hepatic artery thrombosis (eHAT) is a severe arterial complication leading to biliary complications and graft failure in living donor liver transplantation (LDLT). This study sought to early identify the abnormal waveforms of eHAT by using intensive Doppler ultrasonography (DUS) after LDLT and to assess the clinical outcome in these eHAT patients. MATERIAL AND METHODS DUS for 419 adult LDLT recipients was performed twice after vascular anastomosis during liver transplantation and once a day at the bedside for at least 2 weeks. RESULTS Nine adult LDLT recipients with eHAT were identified by using bedside DUS with subsequent computed tomography angiography (CTA). All eHAT cases were noted in the first 2 weeks. Five patients with CTA findings of partial thrombus with the small visualized intrahepatic hepatic artery (HA) were treated with intravenous thrombolysis (IVT) (medical group). Another 4 patients with CTA findings of extrahepatic HA occlusion and nonvisualization of intrahepatic HAs were treated by arterial re-anastomosis (surgical group). The prevalence of long-term non-anastomotic biliary strictures was 33.3% in the surgical group. Intensive post-LDLT DUS is a convenient and sensitive tool for eHAT detection. CONCLUSIONS Subsequent CTA gives valid information on occluded arteries and associated findings, which impact decision-making and are correlated with patient outcome. Our protocol of DUS has high sensitivity and diagnostic accuracy for use in in eHAT patients with partial occlusion, and it can be applied for IVT treatment, avoiding the need for reoperation and preventing long-term biliary complications.BACKGROUND The aim of this study was to explore the impact of lymphadenectomy and umbilectomy on long-term survival and progression-free survival (PFS) of patients with urachal carcinoma. MATERIAL AND METHODS We performed a retrospective analysis of 39 patients with urachal carcinoma. Clinicopathologic outcomes were evaluated, and overall survival (OS) and PFS were assessed by Kaplan-Meier method and Cox regression analysis. RESULTS Thirty-four (87.2%) patients underwent partial cystectomy, and 3 (7.7%) patients underwent radical cystectomy with en bloc urachal resection. Eighteen (46.2%) patients underwent lymphadenectomy and 27 (69.2%) patients had umbilectomy. Multivariate analysis showed that tumor size (P=0.011), Mayo stage (P=0.012), and umbilectomy (P=0.007) were the independent prognostic factors for OS. The median overall survival time was 67 months. The differentiation degree of tumor (P=0.049), Mayo stage (P=0.004), and umbilectomy (P=0.046) were the independent prognostic factors for PFS. Lymph node resection was not a predictor of OS. Patients had poorer prognosis when the tumor invaded the entire wall, including the mucous layer, muscular layer, and serous layer of the bladder compared with those that invaded only the muscular layer (P=0.014). CONCLUSIONS Lymph node metastases and failure to undergo umbilectomy were the independent prognostic factors for OS and PFS. Lymph node resection was not a predictor of OS. Patients had poorer prognosis when the tumor invaded the entire wall of the bladder compared with those that invaded the muscular layer.The spread of plasmid-mediated colistin resistance has posed a serious threat to public health owing to its effects on the emergence of pandrug-resistant bacteria. In this study, we investigated the prevalence and characteristics of mcr-1-positive Escherichia coli isolated from retail meat samples in Korea. In total, 1,205 E. coli strains were isolated from 3,234 retail meat samples in Korea. All E. link3 coli strains were subjected to antimicrobial susceptibility testing and were examined for the presence of mcr-1 gene. All mcr-1-positive E. coli (n = 10, 0.8%) from retail meat were subjected to pulse-field gel electrophoresis (PFGE) and whole-genome sequencing (WGS). The transferability of mcr-1 gene was determined by conjugation assays. The mcr-1-positive strains exhibited diverse clonal types. Our mcr-1 genes were located in plasmids belonged to the IncI2 (n = 1) and IncX4 (n = 8) types, which were reported to be prevalent in Asia and worldwide, respectively. Most mcr-1 genes from mcr-1-positive strains (9/10) were transferable to the recipient strain and the transfer frequencies ranged from 2.
