CONCLUSIONS Our results support an individualized approach in the diagnostic workup of patients with TD taking host and travel characteristics into account to avoid unnecessary diagnostic testing. Molecular culture-independent diagnostic stool tests provide better coverage of the variety of etiological agents than traditional stool culture and have the benefit of rapid detection. However, the high sensitivity bears challenges differentiating colonization from infection. Genetic fusion of a therapeutic protein to albumin can improve its stability and pharmacokinetics, but it usually leads to considerably reduced bioactivity and poor tumor penetration due to increased steric hindrance, resulting in limited antitumor efficacy. Herein we report head-to-tail macrocyclization of albumin-binding domain fused interferon alpha (IFN-ABD) to form a cyclic fusion protein (c-IFN-ABD) with well-retained albumin-binding affinity. Notably, c-IFN-ABD showed not only greater thermal and enzymatic stability and thus antiproliferative activity than IFN-ABD and IFN due to the macrocyclization, but also exhibited considerably better pharmacokinetics than IFN and cyclic IFN owing to the albumin-binding affinity. More importantly, c-IFN-ABD showed deeper tumor penetration, greater tumor retention, and thus higher antitumor efficiency than all the controls without significant systemic side effects in mice bearing melanoma. These results implicate that head-to-tail macrocyclization of ABD fused therapeutic proteins is an enabling strategy for the design of highly potent protein therapeutics for tumor therapy. Tea plant is an important economic crop, which produces the world's oldest and widely consumed tea beverages. We here present a high-quality reference genome of the tea plant (Camellia sinensis var. CP-673451 in vivo sinensis) consisting of 15 pseudo-chromosomes, 70.38% of which are LTR retrotransposons. We show the evidence that LTR-RTs play critical roles in the genome size expansion and transcriptional diversification of tea plant genes through preferential gene insertions in promoter regions and introns. Genes, particularly those for terpene biosynthesis, associated with tea aroma and stress resistance are significantly amplified forming gene clusters through recent tandem duplications in the tea plant genome. Phylogenetic analyses of the sequences of 81 tea plant accessions of diverse origins revealed three well-differentiated tea plant populations, supporting the proposition for the southwest origin of the cultivated tea plants in China and its later spreading to western Asian through introduction. Domestication and modern breeding left significant signatures on hundreds of genes in the tea plant genome, particularly those associated with tea quality and stress resistance. The genomic sequences of the reported reference and resequenced tea plant accessions provided valuable resources for future functional genomic and breeding research of tea plants and understanding the genome evolution of flowering plants. The transition from open shoulder surgery to arthroscopic shoulder surgery represents a classic paradigm shift. In order for that paradigm shift to have occurred, the early pioneers in this discipline had to assume several burdens of their new craft the burden of "arthroscopic identification"; the burden of developing the language of arthroscopy; the burden of disseminating arthroscopic knowledge; the burden of developing safe arthroscopic instruments and implants; and the burden of proving biomechanical and structural equivalency between arthroscopic and open constructs. Embracing these obligations, they were able to produce the paradigm shift to arthroscopic shoulder surgery through a spirited mix of depth, breadth, and tenacity, defying long odds and conventional wisdom while creating a major breakthrough in shoulder surgery. The American physicist and philosopher Thomas Kuhn coined the term paradigm shift in 1962 in his classic book The Structure of Scientific Revolutions (Ref 1). He defined paradigm shift as a fundamental change in the basic concepts and practices of a discipline. Based on that definition, I believe that the transition from open shoulder surgery to arthroscopic shoulder surgery represents a classic paradigm shift. PURPOSE To assess whether labral size is predictive of labral repair failure or demonstrates association with patient outcomes post-hip arthroscopy. METHODS A retrospective chart review was performed for patients undergoing arthroscopic hip labral repair. Labral size was measured in 4 quadrants with an arthroscopic probe. The average size across torn labral segments was assessed for failure as determined by change in PROs, the rate at which subjects achieved MCID and PASS, and need for additional surgery. Outcomes were evaluated for any continuous correlation as well as significant differences between classes of labral sizes derived from upper and lower quartile and decile ranges against the middle 50%. Included hips were those from patients between the ages 18 and 55 with 2-year postoperative follow up and lateral center edge angles (LCEA) between 25-40°. RESULTS The study included 571 hips. Labral width did not show significant difference between those requiring revision versus those not requiring revision (p= .4054). There was no significant correlation between labral width and the change in preoperative and 2-year postoperative iHOT (R2 = 0.05780), mHHS (R2 = 0.19826), or NAHS (R2 = 0.23543) outcome scores. Those with labral sizes in the upper decile of our cohort showed significantly decreased improvement in the iHOT (p= .0287) and NAHS (p= .0490) when compared to the middle 50% of labral sizes. There was no statistical difference in the rate that the groups achieved MCID or PASS. CONCLUSIONS Hypertrophic labra in the largest 10th percentile demonstrated lower postoperative outcome scores. However, there was no detectable clinical benefit in terms of patient perceived clinical difference or acceptable symptomatic state. For the majority of patients, labral size does not appear to significantly alter patient outcomes or need for arthroplasty.
