Logáil Isteach / Cláraigh
Atmospheric deposition of nitrogen (N) in California ecosystems is ecologically significant and highly variable, ranging from about 1 to 45 kg/ha/year. The lowest ambient concentrations and deposition values are found in the eastern and northern parts of the Sierra Nevada Mountains and the highest

Aging and smoking are known to promote atrophic gastritis (AG) and intestinal metaplasia (IM). This study investigated the relationship between Helicobacter pylori (Hp) infection, aging, smoking, and AG/IM. Ninety-six Hp-negative and 231 Hp-positive subjects were divided according to age; (< or = 39

Distal splenorenal shunt and insulin secretion, plasma glucagon, and glucose homeostasis in cirrhosis.

Logáil Isteach / Cláraigh
Over the 1st postoperative yr, distal splenorenal shunt (DSRS) in cirrhotic patients is followed by a reduction in portal perfusion resulting from a spontaneous opening of portal-systemic collaterals. This can influence plasma levels of insulin and glucagon. Fasting plasma glucose, insulin,

Logáil Isteach / Cláraigh
Transition metal molybdenum (Mo) exhibits a strong capacity to adsorb nitrogen (N2), but the Mo-N2 interaction is too strong and thus it is difficult for ammonia (NH3) to be released from the catalyst surface. Bonding with nonmetals with strong electronegativity is helpful to weaken the Mo-N2

Logáil Isteach / Cláraigh
The impacts of nitrogen deposition on a typical acidified soil under a masson pine (Pinus massoniana) forest at Tieshanping, Chongqing in Southwest China was studied through field experiments. The changes of soil water chemistry in different layers within one year after the spray of NH4NO3 and NaNO3

Air quality across the northern hemisphere over the past two decades has witnessed dramatic changes, with continuous improvement in developed countries in North America and Europe, but a contrasting sharp deterioration in developing regions of Asia. This study investigates the historical trend in

The predictive value of donor liver biopsies for the development of primary nonfunction after orthotopic liver transplantation.

Ní féidir ach le húsáideoirí cláraithe ailt a aistriú
Logáil Isteach / Cláraigh
Methods of accurately assessing the suitability of donor livers prior to transplantation are required if the incidence of primary nonfunction (PNF) is to be reduced. This study evaluated the ability of donor liver biopsies to predict the development of primary nonfunction after transplantation. From
