Nonetheless, the findings partially supported the predictions of the EICA hypothesis because invasive genotypes were generally taller than native genotypes, but did not fully support the hypothesis because they were not always more damaged than the native genotypes by C. schaffneri. Conclusion Invasive genotypes had an advantage in the introduced range as they can climb neighbouring vegetation more quickly than native genotypes, but the damage incurred by the invasive genotypes relative to the native genotypes suggests only that C. schaffneri would be as damaging in South Africa, where it serves as a biocontrol agent, as it is in its native distribution in Brazil.Trypanosoma brucei (T. brucei) is the causative agent of Human African Trypanosomiasis (HAT). Nitrogen-containing bisphosphonates, a current treatment for bone diseases, have been shown to block the growth of the T. brucei parasites by inhibiting farnesyl pyrophosphate synthase (FPPS); however, due to their poor pharmacokinetic properties they are not well suited for anti-parasitic therapy. Recently, an allosteric binding pocket was discovered on human FPPS, but its existence on trypanosomal FPPS was unclear. Here, we applied NMR and X-ray fragment screening on T. brucei FPPS and report on four fragments bound to this previously unknown allosteric site. Surprisingly, non-bisphosphonate active-site binders were also identified. Moreover, fragment screening revealed a number of additional binding sites. In an early structure-activity relationship (SAR) study, an analogue of an active-site binder was unexpectedly shown to bind to the allosteric site. Overlaying identified fragment binders of a parallel T. ICI-118551 chemical structure cruzi FPPS fragment screen with the T. brucei FPPS structure and medicinal chemistry optimization based on two binders revealed another example of fragment "pocket hopping". The discovery of binders with new chemotypes sets the framework for developing advanced compounds with pharmacokinetic properties suitable for the treatment of parasitic infections by inhibition of FPPS in T. brucei parasites.Studies evaluating the effects of multiple occupational exposures on sleep are very rare. We assessed the associations between a wide range of occupational exposures and sleep problems and investigated the cumulative effects of these exposures on this outcome. We used data from the French 2016 Working Conditions survey conducted on a nationally representative sample of workers, including 20,430 employees aged 15-65 yr (8,579 men, 11,851 women). Sleep problems were defined by either sleep disturbances or sleep medication, almost daily or several times a week. Occupational exposures included 21 psychosocial work factors grouped into five dimensions, four factors related to working time/hours and four factors related to the physical work environment. Unadjusted and adjusted weighted robust Poisson regression analyses were performed. Almost all psychosocial work exposures were associated with sleep problems, whereas the only significant working time/hours factor associated with sleep problems was night work among women. Some gender differences in the exposure-outcome associations were found. The prevalence ratio of sleep problems increased with the number of exposures for most dimensions of psychosocial work factors. Physical work exposures were associated with sleep problems, and there was a linear association between the number of these occupational exposures and sleep problems in both genders, although the trend did not reach statistical significance among women. Workplace preventive strategies targeting the work environment comprehensively may be effective in improving sleep among working populations. More attention should be given to multiple exposures in the workplace.Background and aim Tubulointerstitial nephritis antigen like 1 (TINAGL1), as a novel matricellular protein, has been demonstrated to participate in cancer progression, whereas the potential function of TINAGL1 in gastric cancer (GC) remains unknown. Methods The expression pattern of TINAGL1 in GC was examined by immunohistochemistry, ELISA, real-time PCR and western blot. Correlation between TINAGL1 and MMPs analyzed by the GEPIA website and KM plots database. The lentivirus based TINAGL1 knockdown, CCK-8, Transwell assays were used to test the function of TINAGL1 in vitro. The role of TINAGL1 was confirmed by subcutaneous xenograft, abdominal dissemination, and lung metastasis model. Microarray experiments, ELISA, real-time PCR and western blot were used to identify molecular mechanism. Results TINAGL1 was increased in GC tumor tissues and associated with poor patient survival. Moreover, TINAGL1 significantly promoted GC cell proliferation and migration in vitro as well as facilitated GC tumor growth and metastasis in vivo. TINAGL1 expression in GC cells was accompanied with increasing matrix metalloproteinases (MMPs) including MMP2, MMP9, MMP11, MMP14 and MMP16. GEPIA database revealed that these MMPs were correlated with TINAGL1 in GC tumors, and that the most highly-expressed MMP was MMP2. Mechanically, TINAGL1 regulated MMP2 through the JNK signaling pathway activation. Conclusions Our data highlight that TINAGL1 promotes GC growth and metastasis and regulates MMP2 expression, indicating that TINAGL1 may serve as a therapeutic target for GC.The current paradigm for the diagnosis of haemophilia and other inherited bleeding disorders (IBDs) based on clinical assessment followed by screening tests and confirmation by assays of clotting factor levels or platelet functions is complex and cumbersome. These have been difficult to establish and standardize around the world for many reasons. Therefore, more than half of the expected number of people with these disorders in the world remain unidentified. A new approach is therefore needed. Use of validated bleeding assessment tools (BATs) offers an opportunity for standardized evaluation of clinically significant bleeding at the primary care level or even to be self-assessed. Advances in genetic evaluation of these disorders through gene panels covering a wide range of IBDs based on next generation sequencing (NGS) technology enable the identification of the primary defect in the haemostasis system with high degree of accuracy. These methods can be centralized and made highly cost-effective when done in large batches.
