Understanding tree growth as a function of tree size is important for a multitude of ecological and management applications. Determining what limits growth is of central interest, and forest inventory permanent plots are an abundant source of long-term information but are highly complex. Observation error and multiple sources of shared variation (spatial plot effects, temporal repeated measures...

Pentastomiasis is an emerging snake-borne parasitic zoonosis in the tropics. We describe a molecular and morphological study to diagnose a cluster of asymptomatic abdominal human infections caused by Armillifer grandis. The findings may indicate a silent epidemic in a rural area where severe symptomatic ocular cases with the same parasite species have recently surfaced. Molecular diagnostics ar...

Xanthine oxidase inhibitory activity has been reported from different plants such as Cinnamomum cassia, Chrysanthemum indicum, Lycopus europaeus, Polygonum cuspidatum, Acacia confuse, Coccinia grandis, Datura metel, Strychnos nux-vomica, Vitex negundo, Coccinia grandis, Vitex negundo, Fraxinus angustifolia, Pistacia lentiscus, Hyptis obtusiflora, H. lantanaefolia, Artemisia vulgaris, Caesalpini...

The thermal behavior of lignins from softwood and hardwood species has been investigated using thermogravimetry and differential scanning calorimetry. Klason Lignin from Pinus taeda and Klason lignin from Eucalyptus grandis were studied. The differential scanning calorimetry results showed that both Klason lignins studied presented similar glass transition temperature. Thermogravimetric results...

The aim of the present study is to find the effectiveness of reported phytocompounds from Coccinia grandis fruits against Alzheimer's disease. Acetylcholinesterase is an important target in the treatment of Alzheimer's disease and it was taken as a receptor for this study. The reported phytocompounds were taken as ligand molecules and the 3D structure of human acetylcholinesterase was retrieved...

A growth regulator (G; 4-ethyl-1-hydroxy-4,8,8,10,10 pentamethyl-7,9-dioxo-2,3 dioxyabicyclo (4.4.0) decene-5) from Eucalyptus grandis (Maiden) reduced stomatal conductance and also photosynthetic capacity when fed through the transpiration stream of detached leaves. The concentration of G required for this effect was high (10(-4) molar), but the amount of G taken up (dose) was below the level ...

The distributions of American cicada killers (Sphecius) were examined via solicited and museum specimens. S. hogardii occurs in southern Florida and several Caribbean islands. S. speciosus occurs throughout the east coast, southeast, and Midwestern states at high densities, and its range extends much farther west than expected, but not west of the continental divide. S. speciosus appears to be ...

The interest has increased in the consumption of Citrus fruits, it is not only due to their sweet refreshing properties but also because of their other important properties like medicinal, antioxidant and nutritional values . Four different indigenous varieties of Citrus namely Citrus grandis var Robab, Citrus grandis var Khaloi, Citrus sinensis var Valencia, and Citrus sinensis var Sohniangria...

Cholesterol oxidase represents a novel type of insecticidal protein with potent activity against the cotton boll weevil (Anthonomus grandis grandis Boheman). We transformed tobacco (Nicotiana tabacum) plants with the cholesterol oxidase choM gene and expressed cytosolic and chloroplast-targeted versions of the ChoM protein. Transgenic leaf tissues expressing cholesterol oxidase exerted insectic...
