Banding of esophageal varices was done in 29 patients suffering from acute variceal bleeding. In 13 patients this was the first bleed while in 16 it was recurrent. Five patients had large grade III (polypold) varices while others had grade II varices. Banding was done using multi band ligator and 4-6 bands were fired per session. Repeat endoscopy at 3 weeks revealed persistance of varices requi...

Aneuploidy has previously been observed in the Pacific oyster, Crassostrea gigas, and shown to be negatively correlated with growth. Moreover, a significant impact of atrazine exposure has been described in C. gigas, and persistence of that effect has been observed between generations. Evidence of differential chromosome loss has been demonstrated in aneuploid karyotypes of C. gigas using the G...

The metastatic potential of nonsmall cell carcinoma of lung (NSCLC), is currently recognized post factum, when lymph nodes or distant organs are already involved. Our ability to determine which tumors have acquired metastatic potential could help direct therapy to be more aggressive or less aggressive based upon this information. Evaluation of microsatellite instability via detection of LOH at ...

It is shown by a crystallographic etching technique that deformation banding is an important deformation mode in copper. In a cold rolled coarse grain copper, deformation banding forms in a three dimensional manner dividing grains into a large number of bands of different orientations. The influence of this important, but long ignored deformation mode, is studied by incorporating it into the Ta...

Poultry litter is known to be an excellent organic fertilizer, but the common practice of spreading litter on the surface of pastures has raised serious water-quality concerns and may limit potential benefits of litter applications. Because surface-applied litter is completely exposed to the atmosphere, runoff can transport nutrients into nearby streams and lakes, and much of the ammonium nitro...

studies of postmeiotic chromosomes have been impeded by the thick exine of immature pollen grains. chromosome staining of immature and adult pollen grains through conven-tional acetocarmine procedure is tedious and often leads to unsatisfactory results. an acetocarmine stain, used in conjugation with carnoy’s solution as fixative for 72 hrs or until the chlorophyll-containing tissues of spike b...
