Functional results are satisfactory.PirAB toxin was initially found in the Photorhabdus luminescens TT01 strain and is a demonstrated binary toxin with high insecticidal activity. In this paper, we co-expressed the pirAB gene of Xenorhabdus nematophila HB310 in a prokaryotic expression system, and we found that the PirAB protein showed high hemocoel insecticidal activity against Galleria mellonella, Helicoverpa armigera and Spodoptera exigua. LD50 values were 1.562, 2.003 and 2.17 μg/larvae for G. mellonella, H. armigera, and S. exigua, respectively (p > 0.05). Additionally, PirAB-interaction proteins were identified from G. mellonella by 6 × His Protein Pulldown combined with liquid chromatography-tandem mass spectrometry (LC-MS/MS). Of which, arylphorin of G. mellonella showed the highest matching rate. A protein domain conservative structure analysis indicated that arylphorin has three domains including Hemocyanin-N, Hemocyanin-M, and Hemocyanin-C. Among these protein domains, Hemocyanin-C has immune and recognition functions. Further, Hemocyanin-C domain of arylphorin was identified to interact with PirA but not PirB by Yeast two-hybrid system. These findings reveal, for the first time, new host protein interacting with PirAB. The identification of interaction protein may serve as the foundation for further study on the function and insecticidal mechanism of this binary toxin from Xenorhabdus.BACKGROUND Inflammatory osteolysis is the clinical hallmark of peri-implantitis. The morphology of the remaining peri-implant bone and the level of osseointegration, however, remain unknown. Our aim was to characterize advanced peri-implantitis bone defects in humans. METHODS Four patients (3 female and 1 male) were diagnosed with peri-implantitis. A total of 5 implants with machined surfaces and a mean loading time of 12 ± 6 years were removed due to advanced bone loss. The defect extension, the peri-implant bone density (bone area per tissue area in percentage), bone-to-implant contact (%), and the number of filled and empty osteocyte lacunae were calculated based on undecalcified histological specimens. RESULTS The defect extension was on average 4.2 mm (95% CI 0.8-3.4). Remaining peri-implant bone showed a high density of 85.5% (95% CI 79.1-91.3) and covered in total 74% (95% CI 70.5-77.5) of the implant surface. Filled and empty osteocyte lacunae density was on average 191 and 165/mm2 (95% CI 132-251; 103-225), respectively. Histology further revealed signs of ongoing bone formation and resorption. CONCLUSION There are signs that suggest that once the original cortical bone is lost due to peri-implantitis, the remaining apical trabecular bone is reinforced and transformed into cortical bone that might take over the functional load.The aim of our study was to investigate the relationship between maternal age at menarche and newborn telomere length which has been linked to lifespan and many age-related diseases. There were 734 mother-newborn pairs recruited from Wuhan Children's Hospital Wuhan, Hubei Province, China. Age at menarche was self-reported and categorized into three groups (≤ 12 years, 13 years, and ≥ 14 years). Telomere length in cord blood was measured using quantitative real-time polymerase chain reaction and expressed as the ratio of telomere copy number to single-copy gene number (T/S). The mean age at menarche of 734 mothers was 13.1 (± 1.1) years and the adjusted geometric means in the T/S of newborn telomeres in the three groups were 0.693, 0.721, and 0.748 respectively. find more Earlier age at menarche (≤ 12 years), compared with later age at menarche ≥ 14 years, was significantly associated with 7.32% (95% CI - 13.70%, - 0.23%) shorter telomere length in offspring after adjusting for potential confounders.Conclusion Mothers with earlier age at menarche were more likely to give birth newborn with shorter telomere length. Our study provides evidences for the effect of earlier menarche on fetal telomere programming in offspring.What is Known• Newborn telomere length is considered an indicator of lifespan and health outcomes in later life.• The adverse effects of earlier menarche age to their offspring have been found, but its relationship with newborn telomere length has not been assessed before.What is New• This is the first study to explore the relationship of maternal menarche age with newborn telomere length.• We provided primary evidence that earlier maternal age at menarche was associated with shorter newborn telomere length.Fear has been assigned a central role in models of obsessive-compulsive disorder (OCD), but empirical investigations into the emotions that underpin OCD symptoms are few, especially in pediatric samples. Using validated, clinician-led structured interviews, 124 youth with OCD reported on the presence and severity of symptoms across the main symptom dimensions of OCD (aggressive, symmetry, contamination) and the degree to which fear, incompleteness, and disgust accompanied these symptoms. For comparison purposes, the degree of fear, incompleteness, and disgust during symptoms was obtained also from youth with social anxiety disorder (SAD; n = 27) and generalized anxiety disorder (GAD; n = 28). Participants with OCD reported that all three emotions were involved in their symptoms; however, fear was most strongly linked to aggressive symptoms, incompleteness to symmetry symptoms, and disgust to contamination symptoms. Incompleteness differentiated youth with OCD from those with SAD and GAD. No differences for these emotions were found for youth with OCD with versus without the tic-disorder subtype or comorbid autism. A positive association between incompleteness and self-reported hoarding emerged among youth with OCD. Further studies of the emotional architecture of pediatric OCD, and its relationship to etiology and treatment, are warranted.PURPOSE OF REVIEW To present the latest evidence related to the predictors of urinary tract infections (UTIs) and urosepsis after ureteroscopy (URS) for stone disease. RECENT FINDINGS Our review suggests that almost half of all post-URS complications are related to infectious complications although reported rates of urosepsis were low. The use of antibiotic prophylaxis, treatment of pre-operative UTI, and low procedural time seem to reduce this risk. However, the risk is higher in patients with higher Charlson comorbidity index, elderly patients, female gender, long duration of pre-procedural indwelling ureteric stents and patients with a neurogenic bladder and with high BMI. Infectious complications following ureteroscopy can be a source of morbidity and potential mortality. Although majority of these are minor, efforts must be taken to minimise them especially in high-risk patients. This includes the use of prophylactic antibiotics, limiting stent dwell and procedural time, prompt identification and treatment of UTI and urosepsis, and careful planning in patients with large stone burden and multiple comorbidities.
