In the title hydrate, C28H42N2O3·H2O, the central 1,3-diazinan-5-ol ring adopts a chair conformation with the two benzyl substituents equatorial and the lone pairs of the N atoms axial. The dihedral angle between the aromatic rings is 19.68 (38)°. There are two intra-molecular O-H⋯N hydrogen bonds, each generating an S(6) ring motif. In the crystal, classical O-H⋯O hydrogen bonds connect the 1,3-diazinane and water mol-ecules into columns extending along the b axis. The crystal structure was refined as a two-component twin with a fractional contribution to the minor domain of 0...

The structure of the title compound, [CrCl2(tn)2]2[Cr2O7] (tn = propane-1,3-di-amine; C3H10N2), has been determined from synchrotron data. The asymmetric unit contains one Cr(III) complex cation and half a [Cr2O7](2-) anion. In the complex cation, the Cr(III) ion is coordinated by the four N atoms of two propane-1,3-di-amine (tn) ligands in the equatorial plane and by two Cl atoms in a trans configuration, displaying a distorted octa-hedral coordination sphere. The two six-membered rings in the complex cation have an anti chair-chair conformation with respect to each other...

Shoulder arthroscopy offers a minimally invasive surgical approach to treat a variety of shoulder pathologies. The patient can be positioned in either the lateral decubitus or the beach chair position. This note and accompanying video describe the operating room setup for shoulder arthroscopy in the lateral decubitus position, including positioning of the arms, head, and sterile preparation and draping. Appropriate lateral decubitus positioning for shoulder arthroscopy with careful attention to detail will promote ease of surgical intervention and minimize complications...

Idiopathic adhesive capsulitis of the shoulder is a relatively common condition that results in pain and loss of motion due to capsular thickening and fibrosis. Most cases are successfully treated with conservative management including physical therapy and intra-articular steroid injections. If conservative management fails, arthroscopic capsular release allows precise release of thickened capsular tissue with a lower risk of complications and less soft-tissue trauma than manipulation under anesthesia alone...

BACKGROUND: Several modalities of treatment are being used for the management of proximal humerus fractures. Primary hemiarthroplasty in proximal humerus fracture is indicated in three or four part fracture or fracture dislocations. It is also indicated if fracture involves a large area of articular cartilage loss and viability of head is doubtful. We studied the functional outcome of hemiarthroplasty in comminuted proximal humerus fracture. MATERIALS AND METHODS: 29 patients of three or four part proximal humerus fractures, (according to Neer's classification) who underwent primary shoulder hemiarthroplasty were included in this retrospective study...

: The ability to navigate through space involves complex interactions between multiple brain systems. Although it is clear that spatial navigation is impaired during aging, the networks responsible for these altered behaviors are not well understood. Here, we used a within-subject design and [(18)F]FDG-microPET to capture whole-brain activation patterns in four distinct spatial behaviors from young and aged rhesus macaques: constrained space (CAGE), head-restrained passive locomotion (CHAIR), constrained locomotion in space (TREADMILL), and unconstrained locomotion (WALK)...

INTRODUCTION: Sedentariness is associated with chronic health conditions, impaired cognitive function and obesity. Work contributes significantly to sedentariness because many work tasks necessitate sitting. Few sustained solutions exist to reverse workplace sedentariness. Here, we evaluated a chair and an under-table device that were designed to promote fidgeting while seated. Our hypothesis was that an under-table leg-fidget bar and/or a fidget-promoting chair significantly increased energy expenditure...

The objective of this study was to describe the in-seat movement and weight-shifting behavior of full-time wheelchair users. We measured everyday sitting behavior for 192 d across 28 individuals who used manual wheelchairs as their primary mobility device. To obtain the measurements, we used eight thin force sensors placed under participants' wheelchair cushions. On a typical day, participants spent an average of 10.6 +/- 3.0 h in their wheelchair and transferred out of the wheelchair 8.4 +/- 4.3 times. Participants only performed pressure reliefs (90% off-loading of the entire buttocks for at least 15 s) 0...

We report a strategic synthesis of poly(cyclosilane), a well-defined polymer inspired by crystalline silicon. The synthetic strategy relies on the design of a functionalized cyclohexasilane monomer for transition-metal-promoted dehydrocoupling polymerization. Our approach takes advantage of the dual function of the phenylsilyl group, which serves a crucial role both in the synthesis of a novel α,ω-oligosilanyl dianion and as a latent electrophile. We show that the cyclohexasilane monomer prefers a chair conformation...
