classes in N(p,q). We show that X(p,q) with the quotient topology is homeomorphic to the compact, connected quotient space G(p, so(q,Â)) / SL(q,Â), where SL(q,Â) acts on so(q,Â) and the associated Grassmann manifold G(p, so(q,Â)) by g(Z) = gZgt for Z ∈ so(q,Â) and g ∈ SL(q,Â). It follows immediately that X(p,q) is homeomorphic to X(D−p,q), where D = dim so(q,Â) = (1/2)q(q−1) (duality). For each...

The electrical potential difference (P.D.) across the cell membrane was measured in monolayers of HeLa cells. At 37°C in the cells' growth medium, the mean P.D. was found to be —1 5.45 ±0.57 my, the cell interior being negative. In Tris buffer the P.D. was —17.10 ±0.71 my. The PD. was tempera ture sensitive, falling to —11.9 my at 27°Cand —9.12my at 17°C.Increasing extracellular K ...

Small-cell carcinoma of the lung is a highly lethal form of cancer associated with a wide variety of paraneoplastic syndromes. Using the patch-clamp technique, we have directly demonstrated the presence of voltage-gated k4. Na4, and (a24 channels in three cell lines of human small-cell carcinoma, NCI-HI28, NCI-H69, and NCI-HI46. Whole-cell currents were measured from the tumor cells held at —...

To elucidate the significance of tRNA modification for human lymphoid maturation and malignant transformation, the amount of tRNAs having guanosine in place of queuosine, i.e., (Q-)tRNA, was determined in several human lymphomas and leukemias by exchanging the respective unmodified guanosine residue for [3H]guanine, a reaction catalyzed by a specific tRNA transglycosylase from Escherichia coli....

We have examined the responses of energy and protein metabolism to nutrient intake in nine patients with lung carcinoma, of whom none »ere cachexie and only one had distant métastases,compared with nine control patients for elective aneurism surgery, who were comparable in terms of age, body mass index, and smoking habits. Whole-body protein turnover and leucine oxidation were assessed by pri...
