    • Assessment of axial bone rigidity in rats with metabolic diseases using CT-based structural rigidity analysis 

      Smith, M. D.; Baldassarri, S.; Anez-Bustillos, L.; Tseng, A.; Entezari, V.; Zurakowski, David; Snyder, Brian Dale; Nazarian, Ara (British Editorial Society of Bone and Joint Surgery, 2012)
      Objectives: This study aims to assess the correlation of CT-based structural rigidity analysis with mechanically determined axial rigidity in normal and metabolically diseased rat bone. Methods: A total of 30 rats were ...
    • Bulk effect of the deltoid muscle on the glenohumeral joint 

      Rosso, Claudio; Mueller, Andreas M; McKenzie, Brett; Entezari, Vahid; Cereatti, Andrea; Croce, Ugo Della; Ramappa, Arun J; Nazarian, Ara; DeAngelis, Joseph P (Springer Berlin Heidelberg, 2014)
      Background: There remains controversy on the role of the deltoid on glenohumeral translations during basic and pitching motions. We thus studied the passive effect of the deltoid on the deltoid glenohumeral joint center ...
    • Design and manufacture of a novel system to simulate the biomechanics of basic and pitching shoulder motion 

      Entezari, V.; Trechsel, B. L.; Dow, W. A.; Stanton, S. K.; Rosso, C.; Müller, A.; McKenzie, B.; Vartanians, V.; Cereatti, A.; Della Croce, Ugo; DeAngelis, Joseph; Ramappa, Arun Jogi; Nazarian, Ara (British Editorial Society of Bone and Joint Surgery, 2012)
      Objectives: Cadaveric models of the shoulder evaluate discrete motion segments using the glenohumeral joint in isolation over a defined trajectory. The aim of this study was to design, manufacture and validate a robotic ...
    • The efficacy of a lysine-based dendritic hydrogel does not differ from those of commercially available tissue sealants and adhesives: an ex vivo study 

      Villa-Camacho, Juan C; Ghobril, Cynthia; Anez-Bustillos, Lorenzo; Grinstaff, Mark W; Rodríguez, Edward K; Nazarian, Ara (BioMed Central, 2015)
      Background: Hemostatic agents, tissue adhesives and sealants may contribute to a reduction in hemorrhage-associated morbidity and mortality. Towards this end, we have recently developed a lysine-based dendritic hydrogel ...
    • Glenohumeral Joint Kinematics following Clavicular Fracture and Repairs 

      Rosso, Claudio; Nasr, Michael; Walley, Kempland C.; Harlow, Ethan R.; Haghpanah, Babak; Vaziri, Ashkan; Ramappa, Arun J.; Nazarian, Ara; DeAngelis, Joseph P. (Public Library of Science, 2017)
      Background: The purpose of this biomechanical study was to determine the effect of shortened clavicle malunion on the center of rotation of the glenohumeral (GH) joint, and the capacity of repair to restore baseline ...
    • Influence of disruption of the acromioclavicular and coracoclavicular ligaments on glenohumeral motion: a kinematic evaluation 

      Walley, Kempland C.; Haghpanah, Babak; Hingsammer, Andreas; Harlow, Ethan R.; Vaziri, Ashkan; DeAngelis, Joseph P.; Nazarian, Ara; Ramappa, Arun J. (BioMed Central, 2016)
      Background: Changes to the integrity of the acromioclavicular (AC) joint impact scapulothoracic and clavicular kinematics. AC ligaments provide anterior-posterior stability, while the coracoclavicular (CC) ligaments provide ...
    • Microstructural, Densitometric and Metabolic Variations in Bones from Rats with Normal or Altered Skeletal States 

      Luu, Andrew N.; Anez-Bustillos, Lorenzo; Aran, Shima; Araiza Arroyo, Francisco J.; Entezari, Vahid; Rosso, Claudio; Snyder, Brian D.; Nazarian, Ara (Public Library of Science, 2013)
      Background: High resolution μCT, and combined μPET/CT have emerged as non-invasive techniques to enhance or even replace dual energy X-ray absorptiometry (DXA) as the current preferred approach for fragility fracture risk ...
    • Posterior Capsular Plication Constrains the Glenohumeral Joint by Drawing the Humeral Head Closer to the Glenoid and Resisting Abduction 

      DeAngelis, Joseph P.; Hertz, Benjamin; Wexler, Michael T.; Patel, Nehal; Walley, Kempland C.; Harlow, Ethan R.; Manoukian, Ohan S.; Masoudi, Aidin; Vaziri, Ashkan; Ramappa, Arun J.; Nazarian, Ara (SAGE Publications, 2015)
      Background: Shoulder pain is a common problem, with 30% to 50% of the American population affected annually. While the majority of these shoulder problems improve, there is a high rate of recurrence, as 54% of patients ...
    • Preliminary evaluation of a robotic apparatus for the analysis of passive glenohumeral joint kinematics 

      Rosso, Claudio; Müller, Andreas M; Entezari, Vahid; Dow, William A; McKenzie, Brett; Stanton, Stacey K; Li, Daniel; Cereatti, Andrea; Ramappa, Arun J; DeAngelis, Joseph P; Nazarian, Ara; Croce, Ugo Della (BioMed Central, 2013)
      Background: The shoulder has the greatest range of motion of any joint in the human body. This is due, in part, to the complex interplay between the glenohumeral (GH) joint and the scapulothoracic (ST) articulation. ...
    • Thermoplastic Moulding of Regenerated Silk 

      Guo, Chengchen; Li, Chunmei; Vu, Hiep; Hanna, Philip; Lechtig, Aron; Qiu, Yimin; Mu, Xuan; Ling, Shengjie; Nazarian, Ara; Lin, Samuel; Kaplan, David (Nature Publishing Group, 2020-01)
      Early insights into the unique structure and properties of native silk suggested that β-sheet nanocrystallites in silk would degrade prior to melting when subjected to thermal processing. Since then, canonical approaches ...
