Methods and Results: Fifty-six women with secondary lymphedema and 44 women without a history of breast cancer or lymphedema underwent measurement of their upper limbs with DXA, perometry, and bioimpedance spectroscopy. Whether the affected side was the dominant or nondominant arm influenced inter-limb tissue volumes differences (F=16.31 to 35.14; all p smaller than 0.001) and interacted with the severity of lymphedema (F=3.22 to 11.07; all p smaller than 0.05). In the control group, the dominant limb had more lean tissue but less fat than the nondominant limb. In the lymphedema group, increases in fat in

the affected arm were not related to generalized increases in whole body adiposity when the dominant arm was affected. Perometry-measured selleck products volumes and BIS ratios were moderately to highly correlated with inter-limb fat, volume, and total tissue differences found by DXA (r=0.39 to 0.86). Conclusions:

The direction and magnitude of limb composition changes in those with lymphedema are impacted by whether the affected side is the dominant or nondominant limb, as well as the severity of the condition. The stage of tissue composition change may impact on the diagnosis and monitoring as well as treatment of secondary lymphedema.”
“ADP-ribosylation is a post-translational modification of proteins that occurs mostly in response to cellular stress and is catalysed by members of the diverse poly-ADP-ribose (PAR) polymerase (PARP/ARTD) family. The founding member of the family, PARP1, is best recognized for its function as a sensor of DNA strand lesions, but ADP-ribosylation has been implicated check details in transcriptional regulation, chromatin dynamics, telomere maintenance, apoptosis and neuronal signalling. Here we summarize a number

of exciting recent breakthroughs in our understanding of the structural and mechanistic aspects of how PARP1 recognizes DNA, how PARPs are regulated, how ADP-ribose modifications are set onto specific targets and how the cellular machinery recognizes this elusive post-translational modification.”
“To validated the 12-item Health Status Survey (SF-12) this website of Chinese version for evaluating health-related quality of life (HRQL) of Kashin-Beck disease (KBD) patients in Aba Tibetan autonomous area, China. 338 adult KBD patients in Rangtang County of Aba area were investigated with SF-12. Principal component analysis with varimax rotation was used to test the original factor pattern. Internal consistency reliability was assessed by using Cronbach’s alpha. “Known groups” construct validity was assessed by comparing SF-12 component scores between respondents hypothesized to differ in health-related variables. Two latent factors were extracted explaining 69.4 % of the variance of the questionnaire. The factor loadings were mostly according with the principle concept, except for “vitality” (VT) and “social functioning” (SF) scales that loaded heavier on physical component. The Cronbach’s alpha coefficient was 0.
