Barnyardgrass (Echinochloa spp.) is one of the most common and troublesome weeds in paddy rice cultivation. For effective barnyardgrass control, herbicides with high efficacy against the weed and good selectivity for rice are required. 1-Phenyl-5(4H)-4-dialkylcarbamoyltetrazolinones exhibited high activity against barnyardgrass in paddy field experiments. Fentrazamide, 4-(2-chlorophenyl)-N-cycl...
Abstract Introduction Anticholinergic medications are commonly prescribed to older patients, particularly nursing home patients. burden caused by these increases the risk of cognitive impairment, falls, delirium and increased mortality in this patient cohort. There several published tools available assess impact anticholinergic on negative outcomes (e.g. hospitalisation, mortality). The Cogniti...
BACKGROUND We attempted to determine the prevalence of Hepatozoon spp. infection in Mashhad, northeast of Iran, via blood smear parasitology. METHODS The prevalence was investigated by examination of blood smear parasitology, using blood samples collected from 254 dogs (51 strays and 203 privately owned-dogs). RESULTS Two stray dogs (2/51; 3.92%) and two privately-owned dogs (2/203; 0.98%) ...

Ultra-fast liquid chromatography with a photodiode array detector for simple and rapid determination of urea in body fluids of farm animals is described. Blood plasma, milk, and urine samples are treated with trichloroacetic acid and then centrifuged. Supernatants are derivatized at room temperature using p-dimethylaminobenzaldehyde. Samples are separated using a ternary gradient of methanol in...
We previously developed a quantitative autoradiographic tech nique with special forceps for measuring unscheduled DNA synthesis (UDS) in mouse skin after treatment with ultraviolet light in vivo. By this method, we investigated the relationship between the protective role of melanin and UV-induced DNA repair in black-and-white guinea pigs. Flat areas containing a sharp border between pigmented ...

Einstenium-254 (Z = 99, N 155), can be prepared as a target for research into nuclear reaction studies. This work presents structure and calculations of Es-254 Ca-48 20, 28), using the Skyrme-(Time-Dependent)-Energy-Density-Functional formalism. The show initial parts heavy-ion between nuclei which, depending on interaction parameters, lead to capture compound nucleus element 119. For collision...
BACKGROUND Excessive proliferation of pulmonary artery smooth muscle cells (PASMCs) plays an important role in the development of idiopathic pulmonary arterial hypertension (IPAH), whereas a rise in cytosolic Ca2+ concentration triggers PASMC contraction and stimulates PASMC proliferation. Recently, we demonstrated that upregulation of the TRPC6 channel contributes to proliferation of PASMCs is...
Rotational bands of 252,253,254 No and the fission barriers of 254 No at spin 0¯ h and 20¯ h are calculated with the Hartree-Fock-Bogolyubov theory and the Lipkin-Nogami approximate particle number projection. The SLy4 Skyrme force is used in the particle-hole channel. A zero-range force with and without density-dependence is used in the particle-particle channel. The experimental ground state ...
