Background: Optimization of co-cultivation parameters during Agrobacterium-mediated transformation to Oxalis corniculata evaluated were bacterial density, infection period, acetosyringone (AS) concentration and temperature. Five fold efficiency is achieved in transient gus gene expression after optimizing various parameters. The optimized conditions Agrobacterium tumefaciens growth phase A600nm...

Oryctes rhinoceros nudivirus (OrNV) has been known to cause severe disease in coconut palm rhinoceros beetle, Oryctes rhinoceros, in Southeastern Asia and is used as a biological control to reduce the pest population. Here, we report for the first time that the OrNV may have landed on Korea and may be the major pathogen for diseased larvae of Korean horn beetle, Allomyrina dichotoma. After pero...

Cyrtodactylus rosichonariefi sp. nov. is the second newly described species of Bent-toed gecko from Bunguran Island (Great Natuna), Indonesia. This species occurs in the Sekunyam Forest and is differentiated from all other species of the C. semenanjungensis species group of the Thai-Malay Peninsula by having the following unique combination of characteristics: intermediate size (SVL of adult ma...

Epidemiological investigations on Fasciola hepatica fasciolasis were carried out from July 2004 to June 2005 in the Gafsa oases (Tunisia) after the detection of a human case. Three habitats were studied: one in El Gsar and two in Ain Soltan. The prevalence of human infection was 6.6%. The presence of the parasite was detected through serology in 14.3% of cattle, 35% of sheep and 68.4% of goats....

ISSR molecular markers have been used to investigate genetic diversity of oca (Oxalis tuberosa Mol.), an Andean neglected tuber crop species. Sampling procedure allowed a preliminary study of the genetic diversity at the intraand intervarietal levels. Twenty tuber lots conserved in situ in the microcentre of Candelaria and ex situ in the Toralapa Centre (Bolivia) were identified. Four ISSR prim...

Five Oxalis L. plants belonging to three different sections were collected and subjected GC-MS analysis evaluate understand the relationship between them from chemosystematic point of view. The revealed identification characterization thirty seven compounds non-polar chemical classes which nine (two aliphatic hydrocarbons, one diterpene, fatty acid, four acid esters alcohol) identified before g...

Neurodegeneration refers to a condition of neuronal death occurring as a result of progressive disease of long term. It involves degeneration of circumscribed group of neurons that may be functionally or neuroanatomically connected. Parkinson’s disease (PD) is a chronic, progressive neurological disorder. Recent studies have indicated that a part of active compounds extracted from herbal medici...
