AIM To explore the sensitivity of bacteria commonly found in root canals to 254 nm ultraviolet (UV) light, either as individual cells or as participants of a bacterial multilayer. METHODOLOGY The sensitivity of oral bacteria, as individual cells, to UV light was tested by subjecting plates streaked with bacteria to 254 nm UV, at a fluence of 1-20 mJ cm(-2). An experimental model was designed ...

For several years, our laboratory has isolated numerous bacterial strains from soils and wastewater contaminated with toxic compounds in order to find useful bacteria that can degrade phenolic compounds such as phenol, chlorophenol, and nitrophenol. By enrichment, many phenolic compound-degrading bacteria have been isolated (Bae et al., 1996a, b; Baek et al., 2001; Yoon et al., 1999, 2000). Fur...

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%) ...

Problem statement: The study of Malaysian Arabic phoneme is rarely found which make the references work difficult. Specific guideline on Malaysian subject is not found even though a lot of acoustic and phonetics research has been done on other languages such as English, French and Chinese. Approach: This study discussed about the correct and simplest way of Arabic phonemes pronunciation in Mala...

C-reactive protein (CRP) is an acute phase reactant the concentration of which increases significantly following tissue injury or inflammation. It is present in the albumin fraction of the serum of patients and is antigenic upon injection into rabbits. We report here the development of a local latex reagent coated with rabbit anti-CRP. For this purpose CRP was isolated from pooled sera of patie...
