Systematics of Dirca (Thymelaeaceae) based on its Sequences and ISSR Polymorphisms
The genus Dirca consists of three disjunct species of shrubs. Dirca palustris is found in the eastern United States and adjacent Canada; D, occidcntahs is Umited to six counties near the San Francisco Bay in California; and the recently discovered D, mcxicana is known from one isolated population in northeastern Mexico. The three species have been described and classified according to morpholog...
متن کاملHabitat and Reproduction of Dirca mexicana (Thymelaeaceae)
Little is known about the single reported population of Dirca mexicana. I monitored air temperature from mid-2005 through mid-2007, analyzed pH of soil, used the global positioning system (GPS) to define geographical boundaries of the population, explored for additional populations, and studied aspects of sexual and asexual reproduction in situ and among seedlings in greenhouses. Temperature ra...
متن کاملMorphological study of lumbricals - a cadaveric study.
UNLABELLED The apparently simple human function of closing the hand to grasp an object or opening the palm to release it are in reality tasks of considerable mechanical complexity requiring the contraction of many individual muscles Lumbricals are important part of intrinsic musculature of hand. Though several deviations from normal have been described in standard textbooks of anatomy, a review...
متن کاملPhytotoxic and genotoxic effects of ZnO nanoparticles on garlic (Allium sativum L.): a morphological study.
The effects of zinc oxide nanoparticles (ZnO NPs) on the root growth, root apical meristem mitosis and mitotic aberrations of garlic (Allium sativum L.) were investigated. ZnO NPs caused a concentration-dependent inhibition of root length. When treated with 50 mg/L ZnO NPs for 24 h, the root growth of garlic was completely blocked. The 50% inhibitory concentration (IC(50)) was estimated to be 1...
متن کاملThe toxic effect of L-cysteine on the rat retina. A morphological and biochemical study.
Subcutaneous injection of L-cysteine into 4-day-old rats (1.2 mg/gm body weight) leads to permanent retinal dystrophy. When the eyes were examined 4 to 6 weeks later, there was a reduction of ganglion cells to less than 50% of the controls. The inner plexiform layer was reduced to about 60%, and the inner nuclear layer was reduced with approximately one cell layer. The photoreceptors were unaff...
