Lichun Wang, M Bayani Cardenas
Understanding transport in rough fractures from non-Fickian to Fickian regimes and the prediction of non-Fickian transport is critical for the development of new transport theories and many practical applications. Through computational experiments that fall within the macrodispersion regime, we first simulated and analyzed solute transport through synthetic rough fractures with stationary geometrical properties (i.e., fracture roughness σb/〈b〉 and correlation length λ, where b refers to aperture with its standard deviation σb and arithmetic mean 〈b〉) across increasing fracture longitudinal transport domain length L, with L/λ ranging from 2...

BACKGROUND: Chronic low back pain (LBP) is a common musculoskeletal impairment in people with lower limb amputation. Given the multifactorial nature of LBP, exploring the factors influencing the presence and intensity of LBP is warranted. OBJECTIVE: To investigate which physical, personal, and amputee-specific factors predicted presence and intensity of low back pain (LBP) in persons with non-dysvascular transfemoral (TFA) and transtibial amputation (TTA). DESIGN: A retrospective cross-sectional survey SETTING: A national random sample of people with non-dysvascular TFA and TTA...

A 56-year-old man was admitted to our hospital with intermittent right facial numbness for one year and walking instability for six months. Magnetic resonance imaging revealed an ovoid and well-demarcated intra-axial pontine lesion. Cyst fenestration and biopsy were carried out and the diagnosis of enterogenous cyst was made by MRI and pathologic findings. Preoperative symptoms resolved completely three months after surgery and no evidence of recurrence was found during 3 years of follow-up. Although total resection of enterogenous cysts is recommended, cyst fenestration may be useful if the cyst is adherent to vital neurovascular structures...

Glioblastoma (GBM) is the most aggressive type of brain tumor. In this context, animal models represent excellent tools for the early detection and longitudinal mapping of neuronal dysfunction, that are critical in the preclinical validation of new therapeutic strategies. In a mouse glioma model, we developed sensitive behavioral readouts that allow early recognizing and following neurological symptoms. We injected GL261 cells into the primary motor cortex of syngenic mice and we used a battery of behavioral tests to longitudinally monitor the dysfunction induced by tumor growth...
