Intra-abdominal desmoid tumor mimicking local recurrence of renal cell carcinoma after laparoscopic partial nephrectomy.

A 64-year-old man had an intra-abdominal mass that was detected in a follow-up examination after laparoscopic partial nephrectomy for renal cell carcinoma (RCC). CT showed an enhanced mass of 2.5-cm diameter near the right kidney, where partial nephrectomy had been performed.

Gene contents and organization of a mitochondrial DNA segment of the squid Loligo bleekeri.

The nucleotide sequence of a 9240-base pair DNA fragment of the mitochondrial (mt) genome of a squid, Loligo bleekeri, was determined, in which 8 protein and 14 tRNA genes were identified. The gene organization of the mt-genome exhibits a greater resemblance to the gene organization of arthropods and a chiton, Katharina tunicata, than to those of a mussel, Mytilus edulis, and land snails. A cloverleaf-like structure was observed between the genes for subunits 4 and 5 of NADH dehydrogenase (ND4 and -5), which is considered to have originated from histidine tRNA.

Evolution of pulmonate gastropod mitochondrial genomes: comparisons of gene organizations of Euhadra, Cepaea and Albinaria and implications of unusual tRNA secondary structures.

Complete gene organizations of the mitochondrial genomes of three pulmonate gastropods, Euhadra herklotsi, Cepaea nemoralis and Albinaria coerulea, permit comparisons of their gene organizations. Euhadra and Cepaea are classified in the same superfamily, Helicoidea, yet they show several differences in the order of tRNA and protein coding genes. Albinaria is distantly related to the other two genera but shares the same gene order in one part of its mitochondrial genome with Euhadra and in another part with Cepaea.
