Previous studies have indicated that some species of Cuscuta possess anticancer activity on various cell lines. Due to the lack of detailed researches on the cytotoxic effects of Cuscuta chinensis and Cuscuta epithymum, the aim of the present study was to evaluate cytotoxic effects of chloroform and hydroalcoholic extracts of these plants on the human breast carcinoma cell line (MDA-MB-468), hu...

To evaluate antifertility mode of action of extracts of Juniperus communis Linn., its various extracts were investigated for estrogenic, antiestrogenic, progestagenic and antiprogestagenic properties in laboratory animals. Investigations reveal that the extract possessed only antiprogestational activity which accounts for its antifertility effect.

BACKGROUND Juniperus communis L. represents a multi-purpose crop used in the pharmaceutical, food, and cosmetic industry. Several studies present the possible medicinal properties of different Juniperus taxa native to specific geographical area. The present study aims to evaluate the genoprotective, antioxidant, antifungal and anti-inflammatory potential of hydroalcoholic extract of wild-growin...

The Cavitron technique facilitates time and material saving for vulnerability analysis. The use of rotors with small diameters leads to high water pressure gradients (DeltaP) across samples, which may cause pit aspiration in conifers. In this study, the effect of pit aspiration on Cavitron measurements was analysed and a modified 'conifer method' was tested which avoids critical (i.e. pit aspir...

Significance to the Landscape and Nursery Industries In the face of California’s rapid population growth, the competition for increasingly limited water resources has necessitated the use of recycled water for landscape and nursery irrigation. A reference list of the sensitivity of plant species to recycled water would facilitate implementation of recycled water irrigation. The information gene...

The Rancho La Brea tar pit fossil collection includes Juniperus (C3) wood specimens that 14C date between 7.7 and 55 thousand years (kyr) B.P., providing a constrained record of plant response for southern California during the last glacial period. Atmospheric CO2 concentration ([CO2]) ranged between 180 and 220 ppm during glacial periods, rose to approximately 280 ppm before the industrial per...

The recent massive dieback of forest trees due to drought stress makes assessment of the variability of physiological traits that might be critical for predicting forest response and adaptation to climate change even more urgent. We investigated xylem vulnerability to cavitation and xylem specific hydraulic conductivity in seven species of three principal conifer genera (Juniperus monticola, Ju...

In this issue we (Adams and Wingate, pp. 123-133) have presented data that show that J. bermudiana is being subjected to hybridization and likely introgression from Darrell's cedar (J. virginiana var. silicicola) and Smith's cedar (J. v. var. virginiana). Because Dr. Wingate and I have differing philosophies on the conservation of species, we decided to omit conclusions from the previous paper ...

Although considered rare, airborne pollen can be deposited far from its place of origin under a confluence of favorable conditions. Temporally anomalous records of Cupressacean pollen collected from January air samples in London, Ontario, Canada have been cited as a new case of long-distance transport. Data on pollination season implicated Juniperus ashei (mountain cedar), with populations in c...

Evidence was presented in a previous paper' that a hybrid substance, encountered after an antigenic character (ch4) of Streptopelia chinensis was transferred to S. risoria, resulted from the interaction of nonallelic genes. Specifically, the cha4 cellular antigen from chinensis showed no hybrid substance when present in backcross individuals that were homozygous for an independently inherited c...
