BACKGROUND Although the measurement site at L4-L5 for visceral adipose tissue (VAT) has been commonly accepted, some researchers suggest that additional upper sites (i.e., L1-L2 and L2-L3) are useful for estimating VAT volume. Therefore, determining the optimum measurement site remains challenging and has become important in determining VAT volume. We investigated the influence of a single-slic...

OBJECTIVE This study aimed to investigate radiographic fusion rates at L4-5 and L5-S1 after single level posterior lumbar interbody fusion (PLIF) and evaluate the relationship between fusion rates and preoperative disc slope angle (DSA), lumbar lordosis (LL), segmental angle (SA), and pelvic parameters. METHODS We conducted a retrospective review of patients who underwent single level PLIF at...

STUDY DESIGN Retrospective review. OBJECTIVE To determine if lumbarized sacra at the L5-6 level (functional L4-5) are a contraindication to a lateral transpsoas approach. SUMMARY OF BACKGROUND DATA Transitional vertebrae at the lumbosacral junction present mechanical and morphologic changes, though these changes have not been characterized with respect to the feasibility of a lateral transp...

Quantifying spatial distributions and spatially-explicit relationships of soil carbon (C), nitrogen (N) and phosphorus (P) and environmental factors allows us to derive functional relationships and assess anthropogenic induced nutrient imbalances. The objectives of this study were to: (i) characterize geospatial patterns of C, N, and P across a large subtropical region in the southeastern U.S.,...

Partial nerve injury leads to peripheral neuropathic pain. This injury results in conducting/uninterrupted (also called uninjured)sensory fibres, conducting through the damaged nerve alongside axotomised/degenerating fibres. In rats seven days after L5 spinal nerve axotomy (SNA) or modified-SNA (added loose-ligation of L4 spinal nerve with neuroinflammation-inducing chromic-gut),we investigated...

PURPOSE To study the course of L4 to S3 nerve roots and their distance with the ala of the sacrum and the sacroiliac joint. METHODS The embalmed left half pelvis of 25 male and 27 female cadavers aged 30 to 91 (mean, 68) years were studied. The ventral rami of the L4, L5, S1, S2, and S3 nerve roots were dissected along their courses from the corresponding intervertebral foramina to the lesser...

Currently, many learning environments offer little or no support for adaptivity. This is especially regrettable for ordering and presenting the content. In this paper, we outline how adaptability can be applied to e-learning environments. We discuss two environments that support a certain adaptability. We conclude by outlining plans for future adaptability research and development.

ObjectivesThis study described the population structure of M. tuberculosis complex (MTBc) strains among patients with pulmonary or lymph node (TB) in Northwest Ethiopia and tested performance culture isolation MPT64-based speciation for Lineage 7 (L7).MethodsPatients were recruited between April 2017 June 2019 North Gondar, Ethiopia. The MPT64 assay was used to confirm MTBc, spoligotyping chara...
