Based on the Great Western Development Strategy and the requirement for sustainable development in the west of China, rural affordable housing, energy conservation, and environmental protection are becoming development standards in the construction field. This paper mainly explores an innovative, sustainable, residential construction method for rural areas in western China, particularly the int...

There are multiple sites at which the brachial plexus block can be induced in selecting regional anesthesia for upper extremity surgical patients. The most frequently used blocks are axillary, infraclavicular, supraclavicular, and interscalene. One must understand brachial plexus anatomy to use these blocks effectively, as well as the practical clinical differences between the blocks. Axillary ...

BACKGROUND We studied whether increasing L-type calcium current has antiarrhythmic effects. METHODS AND RESULTS Reentrant circuits in the epicardial border zone (EBZ) of healing canine infarcts were mapped during sustained ventricular tachycardia. The cardiac-specific L-type calcium current enhancer Bay Y5959 prevented initiation of sustained ventricular tachycardia in 7 of 14 experiments. Ba...

The phase image generated by radionuclide angiocardiography illustrates the regional timing of ventricular wall motion. In this study the phase image was used to investigate the patterns of ventricular contraction in 103 subjects with either normal hearts or a conduction abnormality. In 38 normal subjects the right ventricle contracted on average 7 ms after the left, and the last region to cont...

Few studies have investigated the spatial clustering of multiple health-related resources. We constructed 0.5 mile kernel densities of resources for census areas in New York City, NY (n=819 block groups), Baltimore, MD (n=737), and Winston-Salem, NC (n=169). Three of the four resource densities (supermarkets/produce stores, retail areas, and recreational facilities) tended to be correlated with...

BACKGROUND The present preliminary study documents the effects of a selective nerve root block (SNB) with short or long acting local anaesthetic compared with baseline measurements in patients with chronic low back pain radiating to the leg with maximum pain in one dermatome (L4). METHODS Ten consecutive patients underwent 20 controlled SNBs at L4 with ropivacaine 0.25% and lidocaine 1% in a ...

PURPOSE Although disease progression of osteoarthritis has been well documented, pain pathophysiology is largely unknown. This study was designed with two purposes: 1) to characterize patients with knee pain predominantly originating from intra-articular structures and 2) to describe the location and pattern of their pain. MATERIALS AND METHODS 103 patients with medial knee osteoarthritis und...
