PURPOSE To evaluate the clinical and ultrasonographic changes in the morphology and vascularity of the common extensor tendon after injecting platelet-rich plasma (PRP) or corticosteroid (CS) for recalcitrant lateral epicondylitis (LE). METHODS 30 patients aged 18 to 60 years with recalcitrant (>6 months) LE not responsive to oral medication or non-invasive treatment were randomised to receiv...

Currently gravity irrigation remains the most widely used in agricultural areas and 90 percent of plantings, the water is applied to the plots by gravity. One of the main problems with these systems is erosion, which is a by product of the erosive forces of water over the row, which brings soil loss and therefore decreases in crop yield. Erosion is the removal of surface soil material caused by...

Processes in hillslope soils present a particular challenge for agricultural production and soil management due to their hydropedological specifics high erosion risk. Soil heterogeneities can cause preferential and/or lateral flow on the entire resulting off-site movement of water, fertilizers chemicals used crop production. A study was conducted under controlled conditions laboratory with undi...

Background and Objectives: The diagnosis of cholesteatoma is usually clinic, the only efficient treatment surgical. High-resolution computed tomography (HRCT) not considered absolutely necessary for management an uncomplicated cholesteatoma, but unsuspected situations from a clinical point view can be discovered using scans, warning surgeon. Our objective to compare HRCT scan information with i...

Erosion in the first year after a wildfire can be up to three orders of magnitude greater than the erosion from undisturbed forests. To mitigate potential postfire erosion, various erosion control treatments are applied on highly erodible areas with downstream resources in need of protection. Because postfire erosion rates generally decline by an order of magnitude for each year of recovery, ef...

In China, the Lower Jingjiang Reach (LJR) of the Yangtze River could be one of the most complicated areas in terms of channel migration. The river had undergone many channel changes in the reach since the 18th century. Intensive human activities in recent decades, such as the construction of upstream dams and revetments, had directly affected the channel migration characteristics. The revetment...

INTRODUCTION Conventionally, posterior C1-C2 fusion has been performed using a sublaminar wiring technique with a structural bone graft. Subsequent advent of newer fixation devices, such as the C1 lateral mass screw and C1 hook, has achieved more solid fixation with improved surgical outcome; however, in these fixation systems, the protruding end of the metal implant above the level of the atla...

Dynamic change in soil erosion is an important focus of regional ecological restoration research. Here, the dynamic changes of soil erosion and its driving forces in the Dahei Mountain ecological restoration area of northern China were analyzed by LANDSAT TM remote sensing captured via geographic information system (GIS) technologies during three typical periods in 2004, 2008 and 2013. The resu...
