ased on the finite element method, effect of porous osteotomy block biomechanics surrounding joints in treatment flat foot by Evans is studied. The method used to simulate for correct flatfoot. force line analyzed from biomechanical point view. blocks were divided into solid and blocks, normal as control groups. results show that can effectively improve foot. Compared with block, also play a co...

Pea (Pisum sativum) roots were treated with aluminum in a calcium solution, and lipid peroxidation was investigated histochemically and biochemically, as well as other events caused by aluminum exposure. Histochemical stainings were observed to distribute similarly on the entire surface of the root apex for three events (aluminum accumulation, lipid peroxidation, and callose production), but th...

A genetic polymorphism has been shown in man for the metabolism of isoniazid (Knight, Selin, and Harris, 1959; Evans, Manley, and McKusick, 1960; Sunahara et al., 1963a, b), and has been shown to control acetylation (Evans, 1962; Jenne, 1963; Evans and White, 1964; Peters, Miller, and Brown, 1965). The acetylation of sulphadimidine (sulfamethazine) has been found to be under the same genetic co...

Stalks and loricae of chrysomonads were studied by fluorescence microscopy employing Calcoflor White-Evans blue (CW-Eb) staining, and by uranyl acetate staining of dried, whole mount preparations for electron microscopy. These structures were composed of microfibrils approximately 4 nm in diameter embedded in a matrix. The organization of the loricae of Poterioochromonas malhamenesis, "Amimonas...

Despite severe and persistent criticism of her research, Alice Evans persevered in her pioneering work on the bacterial contamination of milk, identifying the organism that caused undulant fever and demonstrating that drinking unpasteurized cow's milk could transmit the disease, undulant fever, to humans. The opprobrium that Alice Evans endured was unrelenting, even after her election as the fi...

Ventricular enlargement in normal aging frequently forces the radiological diagnosis of hydrocephalus, but the reliability of Evans' index as a radiological marker of abnormal ventricular enlargement (values > 0.30) during aging is not assessed. Here we analyze ventricular size during aging and the reliability of Evans' index as a radiological marker of abnormal ventricular enlargement. We calc...
