Auxin affects the shape of root systems by influencing elongation and branching. Because multidrug resistance (MDR)-like ABC transporters participate in auxin transport, they may be expected to contribute to root system development. This reverse genetic study of Arabidopsis thaliana roots shows that MDR4-mediated basipetal auxin transport did not affect root elongation or branching. However, im...

the resistant* of patesa against lateral displacement (le. the stability), was studied tinder a range of conditions in vitro, at a range of knee flexion angles. muscle forces were applied in physiological directions along the separate quadriceps muscles. normal muscle actions with constant tension showed constant patellar stability up to sixty degrees knee flexion, and then a significant increa...

An EPG (electro-palatographic) corpus of Iwaidja consonant sequences was examined to investigate global consonant timing patterns and the extent of coarticulation and coproduction in nasal+stop and lateral+stop clusters. As observed in other Australian languages (e.g. Warlpiri), there was limited anticipatory coarticulation in certain heterorganic sequences and evidence of coarticulatory resist...

An advanced series resistance model is developed to accurately predict source/drain (S/D) series resistance of complementary metal-oxide semiconductor (CMOS) in the nanometer regime. The series resistance is modeled by dividing into four resistance components named SDE-to-gate overlap, S/D extension, deep S/D, and silicide-diffusion contact resistance considering the nonnegligible doping-depend...

The use of fluoroscopy guidance together with the loss of resistance technique during epidural injections has been advocated lately; moreover, epidural injections in the absence of fluoroscopic guidance have a high rate of inaccurate needle-tip placement during the injections. However, the approach to the lower cervical and upper thoracic epidural space may be challenging due to its obscure lat...

Soil microbiota represent one of the ancient evolutionary origins of antibiotic resistance and have been proposed as a reservoir of resistance genes available for exchange with clinical pathogens. Using a high-throughput functional metagenomic approach in conjunction with a pipeline for the de novo assembly of short-read sequence data from functional selections (termed PARFuMS), we provide evid...

BACKGROUND Rotator cuff repair retear rates range from 25% to 90%, necessitating methods to improve repair strength. Although numerous laboratory studies have compared single-row with double-row fixation properties, little is known regarding regional (ie, medial vs lateral) suture retention properties in intact and torn tendons. HYPOTHESIS A torn supraspinatus tendon will have reduced suture ...

To determine if mature coronary collateral vascular smooth muscle contains functioning a-adrenergic receptors, we studied 13 dogs, 6-10 months after circumflex ameroid occlusion. Regional myocardia) blood flow was measured with radioactive microspheres in a blood-perfused heart preparation at constant aortic pressure (80 mm Hg). Normal zone resistance was calculated as aortic pressure divided b...

introduction: vertical root fracture inevitably leads to tooth extraction. thus, root filling with obturating materials and sealers that can reinforce the tooth would be an ideal way to reduce fracture in root treated teeth. this study aimed to assess the fracture resistance of roots following the application of different sealers including epiphany, iroot sealer and ah-plus. methods and materia...
