It has been hypothesized that increasing atmospheric CO(2) concentration enhances accumulation of carbon in fine roots, thereby altering soil carbon dynamics and nutrient cycling. To evaluate possible changes to belowground pools of carbon and nitrogen in response to elevated CO(2), an early and a late successional species of pine (Pinus taeda L. and Pinus ponderosa Dougl. ex Laws, respectively...

Seventy-seven patients with ectopic pregnancy underwent culdocentesis; the tap was positive in 70%, negative in 10% and inadequate in 20%. A positive tap was significantly associated with a low hematocrit but was often obtained in patients without hypotension, tachycardia, peritoneal irritation or tubal rupture. While patients with peritoneal irritation were significantly more likely to have a ...

INTRODUCTION Many papers have reported that TAP block provides effective postoperative analgesia, but the sole use of TAP block for surgical anesthesia has been rarely reported. CASE PRESENTATION Therefore, we presented an 80-year-old male undergoing ultrasound-guided unilateral subcostal TAP block providing surgical anesthesia for open gastrostomy. Left subcostal TAP block was performed usin...

To unravel the functions of cell wall and vacuolar invertases in carrot, we used an antisense technique to generate transgenic carrot plants with reduced enzyme activity. Phenotypic alterations appeared at very early stages of development; indeed, the morphology of cotyledon-stage embryos was markedly changed. At the stage at which control plantlets had two to three leaves and one primary root,...

Purpose of Review Transversus abdominis plane (TAP) block is a regional technique for analgesia of the anterolateral abdominal wall. This review highlights the nomenclature system and recent advances in TAP block techniques and proposes directions for future research. Recent Findings Ultrasound guidance is now considered the gold standard in TAP blocks. It is easy to acquire ultrasound images...

fars province is one of the natural habitats of pyrus species in iran. harvesting of fruits, deforestation, expansion of agriculture and overgrazing in recent years has threatened the wild pear open forests and imposed detrimental effects on their natural regeneration, therefore, investigation on propagation of wild pear species for afforestation is needed. this research was carried out to deve...
