In pernicious anemia, vitamin B12 deficiency develops owing to the failure of gastric intrinsicfactor secretion. Patients with this disease absorb vitamin B12 from the gastrointestinal tract when it is fed together with an extract of hog pyloric mucosa. Some patients have relapsed during the course of oral therapy with this mixture (1-3). These subjects absorb vitamin B1.2 administered with nor...

1. Among group B hemolytic streptococci one serological type previously described as homogeneous has been shown, instead, to contain two closely related types, distinguishable by reciprocal absorption experiments. These streptococci are designated Types Ia and Ib. 2. Homologous organisms in each case absorb all antibodies from their respective antisera, while organisms of the heterologous relat...

Atoms of each element in the ground state have a specific electron configuration. These atoms can absorb quanta of light energy when that energy exactly matches the energy associated with any of the allowed electronic transitions within that atom. (See Figure 1.) Atoms that absorb energy are said to be in an excited state. Their electrons absorb exact quanta of energy, elevate to higher energy ...

A 72-year-old female patient underwent successful deployment of a single 3.0 18 mm Absorb bioresorbable vascular scaffold (Abbott Vascular, Santa Clara, California) to the mid right coronary artery (Figures 1A and 1B). The scaffolded segment was imaged simultaneously with coronary angiography and with the C7 Dragonfly (LightLab Imaging Inc., St. Jude Medical, Westford, Massachusetts) optical co...

heavy metals found in urban air with its toxic effects have a direct impact on human health. selection of appropriate tree species and shrub refining capacity of heavy metals in urban areas can greatly reduce the toxic effects of these materials. this study aimed to identify the most suitable tree and shrub species of broadleaf evergreen, deciduous and coniferous refinement of heavy metals lead...
