    Notes: Summary We have isolated two non-allelic nuclear mutants of Neurospora crassa that are temperature-sensitive for the production of cytochromes aa 3 and b. When grown at 23 °C the mutants are virtually indistinguishable from the parent wild-type strains. When grown at 41 °C the mutants have large amounts of KCN-insensitive respiration and lack cytochromes aa 3 and b. Further examination of the mutants revealed that they were extremely deficient in their capacity for mitochondrial protein synthesis when grown at 41 °C. This protein synthesis deficiency appears to be related to a virtual absence of both small and large mitochondrial ribosomal subunits following growth at 41 °C. Examination of the mitochondrial RNAs of the mutants suggests that mitochondrial rRNAs are synthesized in greatly reduced amounts or that they are misprocessed when these mutants are grown at the non-permissive temperature.

    Notes: Summary Seventy-eight male New Zealand white rabbits were autopsied and found to have variable left extra-testicular venous anatomy. Our observations reveal that in the rabbit the left testis is drained in one of three ways, identified as either A (18%), B (30%) or C (52%) —type drainage. The right testicular vein in all cases drained directly into the inferior vena cava immediately superior to the right iliolumbar vein. In type A drainage, the left testicular vein drained directly into the inferior vena cava at the level of the left iliolumbar vein. In type B drainage, the left testicular vein emptied into the left iliolumbar vein, which in turn drained into the inferior vena cava. In type C drainage both the left testicular and iliolumbar veins anastomosed to form a “lumbotesticular” trunk which emptied directly into the left renal vein. These three patterns of left venous vascular anatomy in the rabbit can be explained on the basis of their embryologic development. Our observations suggest that it is the caudal segment of the left pelvic subcardinal vein and its anastomosis with the caudal cardinal complex which persist as the left testicular vein and that the more cranial segment of this vein, heretofore presumed to remain patent, atrophies to the level of the developing left renal vein.

    Notes: Abstract For three stereo-structural models of deoxymyoglobin (Mb) and deoxyhemoglobin (Hb) we derive electronic configurations and their mutual spin-orbit coupling. From the temperature dependent molecular electric field gradient (EFG) tensor we calculate temperature dependent quadrupole splittings, ΔE q(T), asymmetry parameters, η(T), and orientations of the EFG component V zz(T) with respect to the heme group. Comparing theoretical and experimental data we find a molecular electronic structure, which then is used to compute temperature dependent magnetic susceptibilities, χ(T). Theoretical and experimental χ(T) data are in reasonable agreement. From the consistency of our model calculations with experimental results we conclude that iron in Mb and Hb probably is pentacoordinated and considerably out of the heme plane by 0.4–0.8 Å.
