Cell death and wing reduction during the metamorphosis of sex-specific flightless morphs in winter geometrid moths.

Winter geometrid moths show striking sexual dimorphism by having female-specific flightless morphs. The evolutionary grades of wing reduction in winter geometrid moths vary and range from having short wings, vestigial wings, to being wingless. Although the ontogenetic processes underlying the development of the wingless or short-wing morphs in Lepidoptera has been well studied, the mechanisms underlying the development of vestigial wing morphs in winter geometrid moths during metamorphosis are poorly understood.

Effect of dietary fish oil intake on ubiquitin ligase expression during muscle atrophy induced by sciatic nerve denervation in mice.

Dietary fish oil intake improves muscle atrophy in several atrophy models however the effect on denervation-induced muscle atrophy is not clear. Thus, the aim of this study was to investigate the effects of dietary fish oil intake on muscle atrophy and the expression of muscle atrophy markers induced by sciatic nerve denervation in mice. We performed histological and quantitative mRNA expression analysis of muscle atrophy markers in mice fed with fish oil with sciatic nerve denervation.

Cloning and sequencing of the levansucrase gene from Acetobacter xylinum NCI 1005.

The levansucrase gene (lsxA) was cloned from the genomic DNA of Acetobacter xylinum NCI 1005, and the nucleotide sequence of the lsxA gene (1,293 bp) was determined. The deduced amino acid sequence of the lsxA gene showed 57.4% and 46.

Structure-activity relationships of 3-methyl and 3,3-dimethyl analogs of 2-(2,4-difluorophenyl)-3-(omega-substituted alkyl)sulfonyl-1-(1H-1,2,4-triazol-1-yl)-2-propanols.

3-Methyl and 3,3-dimethyl analogs of 2-(2,4-difluorophenyl)-3-(omega-substituted alkyl)sulfonyl-1-(1H-1,2,4-triazol-1-yl)-2-propanols were synthesized and evaluated for their antifungal activities against Candida albicans and Aspergillus fumigatus. The 3,3-dimethyl analogs were found to have more potent activity both in vitro and in vivo than the corresponding 3-mono-methyl analogs. The prophylactic efficacy of the lead compounds against murine systemic candidiasis and aspergillosis was improved significantly by dimethylation of the 3-position.
