An agamic complex of 20- and 10-stamen, black-fruited hawthorns (Crataegus subg. Sanguineae, sect. Douglasianae) occurs in western North America, with a 10-stamen taxon disjunct the upper Great Lakes basin. Here, we recircumscribe 20-stamen taxa at core this (C. ser. Douglasianae). This is needed order to distinguish between presumptively ancestral diploid its allo- autopolyploid derivatives, a...

[1] We use Interferometric Synthetic Aperture Radar (InSAR) to search for surface deformation in the southern Andes (40 S–46 S and 49 S–53 S) associated with magmatic processes. Although the available data are not optimal, we can constrain the amount of volcanic deformation at about 27 Holocene volcanoes between the years 1993–1999. We detect inflation of Cerro Hudson volcano following its 1991...

A New pregnane type Alkaloid named Sracosalgminol [(20S)-20-(dimethylamino)-3β-methoxy-16β-hydroxyl-pregn-5-ene] was isolated from sarcococca saligna and its structure was established on the basis of spectroscopic techniques includingH,13C-NMR and inverse 2D-NMR techniques (DEPT,HMQC and HMBC) UV,MS etc.

Cyclophosphamide (CP) is extensively used as an antineoplastic agent for treatment of various cancers, as well as an immunosuppressive agent. However, despite its wide spectrum of clinical uses, CP is known to cause several adverse effects including reproductive toxicity in humans and experimental animals. Crataegus monogyna is one of the oldest medicinal plant has been shown to be cytoprotecti...

objective: doxorubicin (dox) is a broad spectrum chemotherapeutic agent used in the treatment of several malignancies. the use of dox in clinical chemotherapy has been restricted due to its diverse toxicities, including reproductive toxicity. crataegus monogyna (c. monogyna) is one of the oldest medicinal plants that have been shown to be cytoprotective because of scavenging free radicals. the ...

This study presents the results of anatomic-morphological examination of vegetative (leaves) and generative (flowers, fruits) organs of the endemic plant Crataegus almaatensis Pojark – family Rosaceae, growing in the foothills of Ile Alatau mountains, Almaty region of the Republic of Kazakhstan. The plant Crataegus almaatensis Pojark was examined during the phenological phase of flowering and f...
