We investigated the effects of recent moisture history on the relative production of N2O and N2 during denitrification in soil from cropped and successional ecosystems. The soils were pedogenically identical but had been managed differently for the past decade. Sieved soils were amended with nitrate, glucose, and water. Long-wet and short-wet incubations received 80 and 0%, respectively, of pre...

African mole-rats (Bathyergidae, Rodentia) contain several social, cooperatively breeding species with low extrinsic mortality and unusually high longevity. All social bathyergids live in multigenerational families where reproduction is skewed towards a few breeding individuals. Most of their offspring remain as reproductively inactive "helpers" in their natal families, often for several years....

The origin of the anomalous mole fraction effect (AMFE) in calcium channels is explored with a model of the ryanodine receptor. This model predicted and experiments verified new AMFEs in the cardiac isoform. In mole fraction experiments, conductance is measured in mixtures of ion species X and Y as their relative amounts (mole fractions) vary. This curve can have a minimum (an AMFE). The tradit...

coexistence of a viable fetus with a hydatidiform mole is a rare condition and the diagnosis is very important because of the risk of developing severe complications in pregnancy.the management of these pregnancies is optional, although accurate and great care is required to find early signs of maternal or fetal complications. hereby we report a case of dizygotic twin pregnancy with a complete ...

Inducible cadmium-binding proteins (Cd-BP) in the mussel, Mytilus edulis, were resolved into two molecular weight components, designated Cd-BP10 and Cd-BP20, by gel-permeation chromatography on Sephadex G-75. Each of these two molecular weight components were further resolved into four subcomponents by DEAE-ion-exchange chromatography. All eight subcomponents bound cadmium and exhibited signifi...

Presentation of hydatidiform mole as tubal ectopic pregnancy is very rare. These patients usually present with ectopic pregnancy and are later diagnosed with hydatidiform mole on the basis of histological examination following surgery. We present the case of a 32-year-old female who presented with abdominal pain and vaginal bleed since 2 days of presentation. She was vitally stable. There was m...

Pure tense (T) and relaxed (R) quaternary state polymerized human hemoglobins (PolyhHbs) were synthesized and their biophysical properties characterized, along with mixtures of T- and R-state PolyhHbs. It was observed that the oxygen affinity of PolyhHb mixtures varied linearly with T-state mole fraction. Computational analysis of PolyhHb facilitated oxygenation of a single fiber in a hepatic h...

The mole (Talpa europaea; Insectivora) and the mole rat (Spalax ehrenbergi; Rodentia) both have degenerated eyes as a convergent adaptation to subterranean life. The rudimentary eye lenses of these blind mammals no longer function in a visual process. The crystallin genes, which display a lens-specific expression pattern, were studied in these blind mammals and in related species with normal ey...

This article discusses details study on crystallization , optical properties of Li-Al-Si-La glass containing nanocrystalline LaF3.and their optical energy gaps. The Urbach energy of glass samples was evaluated. By using (2% mole) Tb the green–blue range emission occurred, while by accumulation 1% mole Gd beside Tb, the indigo emission intensity (418 to 441 nm) increased.
