A study was undertaken to explore the content and composition of volatile oil from decaying leaves of lemon-scented eucalypt (Eucalyptus citriodora Hook.) not analyzed earlier. GC and GC-MS analysis of the oil (yield 0.6%) revealed the monoterpenoid nature with citronellal (52.2%), citronellol (12.3%) and isoisopulegol (11.9%) as the major constituents. Overall, 17 components were identified th...

Óleos essenciais são extratos aromáticos altamente concentrados e voláteis obtidos através de plantas. O presente trabalho buscou otimizar informações sobre o potencial econômico terapêutico tais produtos no Brasil. Através da revisão literatura atualização dos dados comerciais existentes, foi possível identificar estudos científicos relevantes que foram selecionados em buscas nas bases eletrôn...

The potential attractant l-octen-3-ol and 3 potential repellents were assayed for activity for Culicoides sonorensis, the primary vector of bluetongue virus in North America. Collections using octenol were low, but numbers in suction traps were greater in the high-octenol treatment (11.5 mg/h) than in the low-octenol treatment (1.2 mg/h) or unbaited control for both sexes. Collections using hig...

This paper presents Hook, a new interaction technique for selecting moving targets. As opposed to existing techniques, Hook uses heuristic methods. It allows pointing in dense 3D environments, and on targets moving with high velocity. Moreover, Hook minimizes the impact of its visual feedback for maintaining user’s interaction comfort. Two adaptations of Hook for 2 dof (degreesof-freedom) and 3...

Background: The leaves of Eucalyptus globulus (eucalyptus) are used for treatment of diabetes mellitus in traditional medicine. The aim of this study was to evaluate the effects of eucalyptus in treatment of established systemic infection with Candida albicans in normal and streptozotocin-induced diabetic rats. Methods: Sixty normoglycemic male Wistar rats, weighing 200-250 g, were selected and...

— We introduce a hook length expansion technique and explain how to discover old and new hook length formulas for partitions and plane trees. The new hook length formulas for trees obtained by our method can be proved rather easily, whereas those for partitions are much more difficult and some of them still remain open conjectures. We also develop a Maple package HookExp for computing the hook ...

In darkness, the dicot seedlings produce an apical hook as result of differential cell division and extension at opposite sides of the hypocotyl. This hook protects the apical meristem from mechanical damage during seedling emergence from the soil. In darkness, gibberellins act via the DELLA-PIF (PHYTOCHROME INTERACTING FACTORs) pathway, and ethylene acts via the EIN3/EIL1 (ETHYLENE INSENSITIVE...

The Mre11-Rad50-Nbs1 (MRN) complex plays critical roles in checkpoint activation and double-stranded break (DSB) repair. The Rad50 zinc hook domain mediates zinc-dependent intercomplex associations of MRN, which is important for DNA tethering. Studies in yeast suggest that the Rad50 zinc hook domain is essential for MRN functions, but its role in mammalian cells is not clear. We demonstrated th...

Effect of aqueous leaf extracts of 8 allelopathic tree species viz., Accacia nilotica (L.) Willd ex Del., Alstonia scholaris (L.) R. Br., Azadirachta indica (L.) A. Juss., Eucalyptus citriodora Hook, Ficus bengalensis L., Mangifera indica L., Melia azedarach L. and Syzygium cumini (L.) Skeels was studied on germination and seed-borne mycoflora of wheat (Triticum aestivum L.). Wheat seeds were s...

Within a single site in the Kohala Forest Reserve, Hawai`i, we examined the composition and diversity of soil microbial communities under four introduced (Cryptomeria japonica, Casuarina equisetifolia, Araucaria columnaris, and Eucalyptus sp.) and one native (Metrosideros polymorpha) canopy tree species, as well as pasture. Terminal restriction fragment length polymorphism (T-RFLP) analysis of ...
