Past long-term reproductive success was sex-specifically reflected in age-corrected telomere length males with on average high fledgling production were characterised by shorter telomeres, whereas successful females had longer telomeres and we discuss hypotheses that may explain this contrast. In conclusion, telomere length and dynamics in relation to age and reproduction are sex dependent in Cory's Shearwaters and these findings contribute to our understanding of what characterises individual variation in fitness. © 2020 The Authors.

Clinical scoring systems and radiological examinations are used to assist in diagnosis. METHODS We reviewed 106 patients between January 2016 and January 2018 who presented with right iliac fossa pain and underwent appendectomy. Their Raja Isteri Pengiran Anak Saleha Appendicitis (RIPASA) scores were calculated and abdominopelvic ultrasonography (USG) was performed before they were operated with a prediagnosis of acute appendicitis. RIPASA scores and USG findings were compared to the histopathological results of appendectomy specimens. RESULTS The histopathological examinations showed that all of the 100 (94.3%) patients whose RIPASA scores were 7 and more had acute appendicitis and the six (5.7%) patients whose scores were less than 7 had no appendicitis. When the appendectomy specimens of the 70 patients who had been diagnosed with acute appendicitis with USG were examined histopathologically, 69 (98.6%) patients were confirmed to have acute appendicitis. Acute appendicitis was found in 18 (81.8%) of the 22 patients whose appendixes could not be visualized with USG. Acute appendicitis was found in eight (88.9%) of the nine patients who had been reported normal with USG. CONCLUSION RIPASA scores should be calculated for all patients who are suspected of having acute appendicitis and for those with a RIPASA score of 7 and more, surgery should be highly recommended without USG. © 2020 Royal Australasian College of Surgeons.The abundance and evolving pathogenic behavior of bacterial microorganisms give rise to antibiotic tolerance and resistance which pose a danger to global public health. New therapeutic strategies are needed to keep pace with this growing threat. We propose a novel approach of targeting bacteria by harnessing formate, a cell metabolite found only in particular bacterial species, to activate an antibacterial prodrug and selectively inhibit their growth. This strategy is premised on transfer hydrogenation (TFH) reaction on a biorthogonal substrate utilizing native formate as the hydride source as a means of uncaging an antibacterial prodrug. Using coordination-directed 3-component assembly (C3A) to prepare a library of 768 unique Ru-Arene Schiff-base (RAS) complexes, we identified several candidates that efficiently reduced sulfonyl azide functional group in the presence of formate. We further designed a caged compound based on antibacterial agent sulfanilamide containing a sulfonyl azide group in place of sulfonamide as a prodrug. The lead RAS complex triggered prodrug activation in Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli), which evolved multiple formate biosynthesis pathways, but not Mycobacterium smegmatis (M. smegmatis), with limited formate biosynthesis capacity, nor mammalian cells, which are deficient in endogenous formate. This strategy paves the way for a new approach of targeted antibacterial therapy by exploiting unique bacterial metabolites. © 2020 WILEY-VCH Verlag GmbH & Co.

Microfibrils dysfunction is responsible for the onset of various connective tissue diseases, including Marfan syndrome. Although ADAMTSL (a disintegrin and metalloproteinase with thrombospondin motifs-like) 6β is one of the fibrillin-1 binding proteins, the detailed mechanism underlying the involvement of ADAMTSL6β in microfibril formation remains unclear. In this study, we created deletion mutants of ADAMTSL6β and examined their interactions with fibrillin-1 assembly. Pull-down assay of the ADAMTSL6β deletion mutants and fibrillin-1 protein revealed that ADAMTSL6β binds to fibrillin-1 through the third thrombospondin type I domain. Furthermore, we observed that formation of fibrillin-1 matrix assembly was enhanced in MG63 cells, expressing full-length ADAMTSL6β, when compared with that of wild type MG63 cells. While MG63 cells expressing Δ TSP3-ADAMTSL6β form showed enhanced assembly formation, Δ TSP2-ADAMTSL6β form did not enhance that, indicating the difference between Δ TSP2-Δ TSP3 has a critical role for fibrillin-1 assembly. As the difference of Δ TSP2-Δ TSP3 is the third thrombospondin type I domain, we concluded that the third thrombospondin type I domain of ADAMTSL6β influence the microfibril formation. Our data are the functional presentation of the biological role of ADAMTSL6β in the process of microfibril formation. © 2020 International Federation for Cell Biology.The olive fruit fly, Bactrocera oleae, causes great damage to the quality and quantity of olive production worldwide. Pest management approaches have proved difficult for a variety of reasons, a fact that has brought about a need for alternative tools and approaches. Here we report for the first time in B. oleae the development of the clustered regularly interspaced palindromic repeats (CRISPR)/CRISPR associated protein 9 (Cas9) gene editing tool, using the well-known eye colour marker gene scarlet. Two synthetic guide RNAs targeting the coding region of the scarlet gene were synthesized and shown to work efficiently in vitro. These reagents were then microinjected along with purified Cas9 protein into early-stage embryos. learn more Successful CRISPR-induced mutations of both copies of the scarlet gene showed a striking yellow eye phenotype, indicative of gene disruption. Multiple successful CRISPR events were confirmed by PCR and sequencing. The establishment of an efficient CRISPR-based gene editing tool in B. oleae will enable the study of critical molecular mechanisms in olive fruit fly biology and physiology, including the analysis of insecticide resistance mechanisms and the discovery of novel insecticide targets, as well as facilitate the development of novel biotechnology-based pest control strategies.
