LEOPARD syndrome is an autosomal dominant hereditary disease, which is characterized with cutaneous pigmented patches, electrocardiographic changes, ocular hypertelorism, retarded growth, pulmonic stenosis, genital abnormalities and congenital deafness. The gene of this disease have high penetrance but expression is varied and incomplete forms may be seen. We report a 23 year-old woman wi...

a semi-batch crystallization system is used to determine growth kinetics and morphology of barium carbonate crystals, under a constant ph value and constant temperature in the various relative supersaturations. results show that crystal growth rate satisfies a first-order kinetic expression at high relative supersaturation, while at relative supersaturation values lower than 3,  the kinetic exp...

The idea that herbaceous plants have higher relative growth rates (RGRs) compared with woody plants is fundamental to many of the most influential theories in plant ecology. This difference in growth rate is thought to reflect systematic variation in physiology, allocation and leaf construction. Previous studies documenting this effect have, however, ignored differences in seed mass. As woody s...

the conditions under which, multilinear forms (the symmetric case and the non symmetric case),can be written as a product of linear forms, are considered. also we generalize a result due to s.kurepa for 2n-functionals in a group g.

Improved methods for studying the growth of Mycoplasma hominis (ATCC 14027) have been developed, involving modified growth conditions and preparation of the organisms under minimally distorting conditions. Cells so prepared from batch cultures show relatively uniform exponential growth and appear to be dividing by binary fission; but pleomorphic forms appear upon further incubation. Similar beh...

During the period from August 1997 to March 1998, two thousand samples of cultured Penaeus semisulcatus postlarvae and subadults were collected from five hatcheries and 20 growout farms distributed in three provinces along the costs of Persian Gulf and the Oman Sea. Based on growth signs, LM and TEM histopathology, Hepatopancreatic Parvo-like Virus (HPV) were identified from the samples. The HP...

In this research, vascular plants of Bamu National Park (48000 ha.) situated in Fars province were studied. Analyses of all collected plants (450 species) showed that on account of climatic conditions, 94% of them were flowering in spring, also hemicryptophytes and therophytes possess abundant growth form with 39.6% and 23.5%, respectively. Phytogeographically, Irano-Turanian  elements comprise...

Dermatofibrosarcoma protuberans is a tumor of intermediate malignancy characterized by its aggressive local growth and marked propensity to recur after surgical excision. Many forms of the tumor has been reported. We report a pedunculated form of tumor. A 45-year-old woman felt a growing tumor on her trunk for 6 years but did not seek medical consultation until it had ulcerated 6 months ago. Sk...

Clonal plants producing both clumping and spreading ramets can adjust their growth forms in response to resource heterogeneity or environmental stress. They might produce clumping ramets to retain favorable patches, or produce spreading ramets to escape from stress-affected patches. This study aimed to investigate the rarely reported concurrent effects of sediment accretion and nutrient enrichm...
