The afforestation of abandoned farmland significantly influences soil organic carbon (OC). However, the dynamics between OC inputs after afforestation and the original OC are not well understood. To learn more about soil OC dynamics after afforestation of farmland, we measured the soil OC content in paired forest and farmland plots in Shaanxi Province, China. The forest plots had been establish...

Development of the sugar beet cyst nematode, Heterodera schachtii, was studied in growth chambers at 20, 25, 29, 32 and 35 ± 1 oC on Beta vulgaris cv. Saccharifera. The optimum temperature for reproduction appeared to be 32 oC, at which the life cycle, from second-stage juvenile (J2) to J2, was completed in 16-19 days; at 35 oC, 20-21 days were required. Juveniles emerged from eggs within 29 da...

In a laboratory experiment an efficacy of entomopathogenic nematode Steinernema feltiae in controlling third-stage larvae of common cockchafer (Melolontha melolontha) was studied. The experiment comprised of commercial product Entonem and indigenous strain C76. The efficacy of both biological agents was tested at 20 and 25 oC and at four different concentrations of nematode suspension: 0, 250.0...

Resumen Cuatro hongos basidiomycetes, Agaricus blazei Murrill (Agaricomycetideae), Ganoderma lucidum (W.Curt.: Fr.) P. Karst. y Grifola frondosa (Dicks.: Fr.) S.F. Gray (Higher Basidiomycetes), y Pleurotus pulmonarius (Fr.) Quél. (Agaricomycetideae) fueron evaluados bajo tres métodos de conservación durante 12 meses, observando su viabilidad con el fin de establecer el mejor método de conservac...

Temperate forests are assumed to be organic carbon (OC) sinks, either because of biomass increases upon elevated CO2 in the atmosphere and large nitrogen deposition, or due to their age structure. Respective changes in soil OC and total nitrogen (TN) storage have rarely been proven. We analysed OC, TN, and bulk densities of 100 soil cores sampled along a regular grid in an old-growth deciduous ...

BACKGROUND Low-dose oral contraceptives (OC) have been reported to control primary dysmenorrhea. Furthermore, a close relationship between dysmenorrhea and uterine contractions has been visualized with magnetic resonance imaging (MRI). This study aimed to use cine MR to demonstrate the effects of OC on myometrial contractility during menstruation and to associate the findings with dysmenorrhea....

OBJECTIVE The present study aimed to determine if schizophrenic patients with OC-symptoms represent a subtype of schizophrenia and to evaluate the differences between schizophrenic patients with OC symptoms and OCD patients. METHODS The study included 20 patients diagnosed with OCD, 40 schizophrenic patients, and 20 schizophrenic patients with OC symptoms. While the distribution and the sever...

The chemical stability of ceftriaxone for injection reconstituted with water was studied at different storage conditions by a validated stability-indicating ion-pair liquid chromatographic method. The study was performed on ceftriaxone for injection samples obtained from two pharmaceutical laboratories, at three different temperatures: 23 oC ± 2 oC, + 8 oC ± 1 oC and 20 oC ± 0.5 oC, over 26 day...

BACKGROUND Evidence suggests that recent oral contraceptive (OC) use is associated with a small increased breast cancer risk; yet risks associated with contemporary OC preparations and by molecular subtype are not well characterized. METHODS We conducted a population-based case-control study of invasive breast cancer among women ages 20 to 44 residing in the Seattle-Puget Sound area from 2004...
