Two genetic linkage maps of cultivated maize inbred lines and teosinte species were constructed. One population comprised 81 F(2) individuals derived from a cross between maize inbred line B73 and Zea mays ssp parviglumis, while the second consisted of 63 backcross individuals from a cross of maize inbred line B73 with Z. mays ssp diploperennis. In the B73 x Z. mays ssp parviglumis F(2) p...

Seven stilbenes, a new cis-epsilon-viniferin and the six known stilbenes, trans-resveratrol, trans-resveratrol-4'-O-beta-D-glucopyranoside, trans-epsilon-viniferin, gnetin H, and suffruticosol A and B, were isolated and identified from seeds of Paeonia lactiflora. The antioxidative activity of these stilbene derivatives was evaluated against the 2-deoxyribose degradation and rat liver microsoma...

Chromosomal meiotic behavior in pollen mother cells (PMCs) of Paeonia emodi, an endangered species, was investigated in natural population represented by nine individuals. The results showed that: (1) Mean chromosome configuration was 2n = 10 = 0.20 I + 4.90 II at metaphase. Most of the chromosomes were ring bivalents, but some were rod bivalents or univalents. The existence of rod bivalent and...

To compare diagnostic performance and confidence of a standard visual reading and combined 3-dimensional stereotactic surface projection (3D-SSP) results to discriminate between Alzheimer disease (AD)/mild cognitive impairment (MCI), dementia with Lewy bodies (DLB), and frontotemporal dementia (FTD).[F]fluorodeoxyglucose (FDG) PET brain images were obtained from 120 patients (64 AD/MCI, 38 DLB,...

AIMS To detect Photobacterium damselae ssp. piscicida using the PCR technique and plating method. METHODS AND RESULTS Two strains of P. damselae ssp. piscicida were isolated from cultured cobia (Rachycentron canadum) at two different fish farms in Taiwan. A pair of primers was designed to detect the capsular polysaccharide gene of P. damselae ssp. piscicida by PCR. Reference strains of differ...

Proof search for the structural synthesis of programs (SSP) — a deductive program synthesis method which is suited for compositional programming in large and is in practical use in a number of programming environments is explained. SSP is based on a decidable logical calculus where complexity of the proof search is still PSPACE. This requires paying special attention to the efficiency of search...

We investigated the effects of herb extracts, Rhus verniciflua, Agrimonia pilosa, Sophora japonica, and Paeonia suffruticosa, on the lowering of blood glucose levels and thiobarbituric acid reactive substances (TBARS) in streptozotocin (STZ)-induced diabetic rats. After 4 weeks, oral administration of Rhus verniciflua extract (50 mg/kg) exhibited a significant decrease in blood glucose levels i...
