What Is the Clinical Value of Long Head of Biceps Tendon Tests in Distal Supraspinatus Tendon Rupture? A Prospective Multicenter Study.

Purpose: The purpose of this study was to determine the clinical value of diagnostic tests for the long head of the biceps tendon (LHBT) injuries in the setting of a Patte stage 1 supraspinatus tendon rupture.

Methods: This was a prospective cohort multicenter study of 361 patients aged 30 to 80 years with Patte stage 1 distal supraspinatus tendon rupture. The LHBT was assessed clinically by palpation of the bicipital groove, the speed test, the Yergason test and the Kibler test.

Long-term Recurrence Rates After Isolated Arthroscopic Bankart Repair in Selected Patients Without Preoperative Bone Loss Versus Open Latarjet Procedure: A Matched-Pair Analysis.

Background: Clinical studies have shown that the open Latarjet procedure (OLP) has lower recurrence rates than the isolated arthroscopic Bankart (IAB) procedure for recurrent anterior shoulder instability, but no long-term comparative studies exist for IAB in patients without bone loss.

Purpose/hypothesis: This study aimed to compare the outcomes of IAB in selected patients without bone loss versus OLP. The hypothesis was that OLP would be more successful in preventing recurrence, even in carefully selected patients for IAB.

Catalytic effects of iron adatoms in poly(-phenylene) synthesis on rutile TiO(110).

-Armchair graphene nanoribbons (nAGNRs) are promising components for next-generation nanoelectronics due to their controllable band gap, which depends on their width and edge structure. Using non-metal surfaces for fabricating nAGNRs gives access to reliable information on their electronic properties. We investigated the influence of light and iron adatoms on the debromination of 4,4''-dibromo--terphenyl precursors affording poly(-phenylene) (PPP as the narrowest GNR) wires through the Ullmann coupling reaction on a rutile TiO(110) surface, which we studied by scanning tunneling microscopy and X-ray photoemission spectroscopy.

Octaethyl vs Tetrabenzo Functionalized Ru Porphyrins on Ag(111): Molecular Conformation, Self-Assembly and Electronic Structure.

Metalloporphyrins on interfaces offer a rich playground for functional materials and hence have been subjected to intense scrutiny over the past decades. As the same porphyrin macrocycle on the same surface may exhibit vastly different physicochemical properties depending on the metal center and its substituents, it is vital to have a thorough structural and chemical characterization of such systems. Here, we explore the distinctions arising from coverage and macrocycle substituents on the closely related ruthenium octaethyl porphyrin and ruthenium tetrabenzo porphyrin on Ag(111).

Can Peer Acceptance and Perceptual Accuracy Impact the Effectiveness of Two Formats of a Preventative Intervention on Functional Subtypes of Aggression in Youth?

Coping Power (CP) is an empirically supported school-based intervention for children at risk for aggression. A child's social status with peers and the extent to which they accurately perceive it are important aspects of preadolescent social development that may influence how intervention format affects disruptive behavior outcomes. Further, reactive (RA) and proactive (PA) functional subtypes of aggression have differential relations with peer acceptance.
