Autor: Xiaoliu Zhang, Alejandro P Comellas, Elizabeth A Regan, Indranil Guha, Amal Shibli‐Rahhal, Mishaela R Rubin, Paul A DiCamillo, Elena M Letuchy, R Graham Barr, Eric A Hoffman, Punam K Saha

Publikováno v: JBMR Plus, Vol 5, Iss 5, Pp n/a-n/a (2021)

ABSTRACT Osteoporosis causes fragile bone, and bone microstructural quality is a critical determinant of bone strength and fracture risk. This study pursues technical validation of novel CT‐based methods for assessment of peripheral bone microstruc

Finite element analysis of trabecular bone microstructure using CT imaging and continuum mechanical modeling

Autor: Indranil Guha, Xiaoliu Zhang, Chamith S. Rajapakse, Gregory Chang, Punam K. Saha

Publikováno v: Medical Physics. 49:3886-3899

Osteoporosis is a bone disease associated with enhanced bone loss, microstructural degeneration, and fracture-risk. Finite element (FE) modeling is used to estimate trabecular bone (Tb) modulus from high-resolution three-dimensional (3-D) imaging mod

Introduction: Smokers with chronic obstructive pulmonary disease (COPD) are at increased risk of muscle weakness. There are limited data describing weakness in smokers with normal spirometry and preserved ratio-impaired spirometry (PRISm), 2 subgroup

3dSpAn: An interactive software for 3D segmentation and analysis of dendritic spines

Autor: Subhadip Basu, Ewa Baczynska, Blazej Ruszczycki, Monika Bijata, Nirmal Das, Jakub Wlodarczyk, Punam K. Saha, Andre Zeug, Dariusz Plewczynski, Evgeni Ponimaskin

Publikováno v: Neuroinformatics. 20:679-698

Three-dimensional segmentation and analysis of dendritic spine morphology involve two major challenges: 1) how to segment individual spines from the dendrites and 2) how to quantitatively assess the morphology of individual spines. To address these t

Bone and non-contractile soft tissue changes following open kinetic chain resistance training and testosterone treatment in spinal cord injury: an exploratory study

Autor: Punam K. Saha, Gregory Chang, Ashraf S. Gorgey, Robert A. Adler, Adam Sima, Maria R. Khan, X. Zhang, Matthew E. Holman, Mina P Ghatas

Publikováno v: Osteoporosis International. 32:1321-1332

Twenty men with spinal cord injury (SCI) were randomized into two 16-week intervention groups receiving testosterone treatment (TT) or TT combined with resistance training (TT + RT). TT + RT appears to hold the potential to reverse or slow down bone
