Complete mitochondrial genome of the mulberry psyllid Paurocephala sauteri Enderlein (Hemiptera: Psyllidae) and phylogenetic analysis.

Paurocephala sauteri (Enderlein, 1914) (Hemiptera: Psyllidae) is a species of a psyllid distributed in Asia. Mulberry is the only known host for P. sauteri until now. The complete mitogenome of P. sauteri (accession number: MT759765) 14,963 bp in size, including 13 protein-coding genes, 22 transfer RNAs, and two ribosomal RNAs genes. The base composition of the whole P. sauteri mitogenome is 40.26% for A, 7.86% for G, 34.07% for T, and 11.81% for C, with a high AT bias of 80.33%. The mitochondrial genome of P. sauteri was sequenced and annotated as the first representative of family Paurocephalidae. The present data could contribute to a detailed phylogeographic analysis of this valuable economic insect for further study in differentiating closely related species.

Clinical significance of heterozygosity loss at Mfn2 gene in hepatocellular carcinoma / 浙江大学学报·医学版

<p><b>OBJECTIVE</b>To investigate the loss of heterozygosity (LOH) at mitofusin-2 (Mfn2) gene in hepatocellular carcinoma (HCC) and its clinicopathological significance.</p><p><b>METHODS</b>Four high polymorphic microsatellite markers flanking Mfn2 were selected for LOH analysis in 29 cases of HCC.</p><p><b>RESULT</b>The frequencies of LOH on D1S2667, D1S2740, D1S434 and D1S228 were 21%, 23%, 21% and 22%, respectively. LOH at Mfn2 was closely correlated with tumor size, age, capsule, differentiation and t HBV infection (P<0.05), not with gender, thrombosis, cirrhosis and serum AFP levels (P>0.05).</p><p><b>CONCLUSION</b>LOH at Mfn2 gene in HCC is associated with the clinicopathological features of patients.</p>

Unique formation of two high-nuclearity metallamacrocycles from a mononuclear complex [Zn(dmpzdtc)2] (dmpzdtc=3,5-dimethylpyrazole-1-dithiocarboxylate) via CS2 elimination.

Dissolution of a mononuclear complex [Zn(dmpzdtc)2] in BrCH2CH2Br or DMF saturated with water followed by CS2 elimination led to the formation of two unique high-nuclearity metallamacrocyclic complexes, [Zn4(micro-dmpz)6(micro-OH)2]2 and [Zn4(micro-dmpz)6(micro-OH)2]4.
