Medicinally important five Phyllanthus species viz. P. acidus (L.) Skeels, emblica L. (small fruit form), (large niruri L., reticulatus Poir. and urinaria were cytogenetically studied through orcein-staining for authentic characterization. This genus showed variation in somatic chromosome numbers such as 2n=2x=26 (x=13) acidus, reticulatus, 2n=6x=48 (x=8) 2n=10x=100 (x=10) (both small large for...

Most members of the subfamily Mimosoideae have pantropical distributions, variable habits, and a basic chromosome number x = 13. We examined karyotypic evolution of 27 species of this subfamily occurring principally in northeastern Brazil by examining chromosomes stained with Giemsa. All of the species had semi-reticulated interphase nuclei and early condensing segments in the proximal region o...

Chromosome numbers in Cyperaceae lower than the typical basic number x = 5 have been described for only three species: Rhynchospora tenuis (n = 2), Fimbristylis umbellaris (n = 3) and Eleocharis subarticulata (n = 3). Eleocharis maculosa is recorded here as the fourth species of Cyperaceae that has a chromosome number lower than 2n = 10, with 2n = 8, 7 and 6. The karyotype differentiation in E....

  Background and Objectives: Primary amenorrhea is not a disease but a symptom that may result from several quite different causes[NN1] . Common hormonal cause of primary amenorrhea includes constitutional delay, hypothalamic –pituitary dysfunction, chronic systemic disease and absent ovarian function. The aim of this study was to estimate the incidence of the chromosomal abnormality referred ...

  Preparation of chromosome spreads and karyotype analysis in Blicca bjoerkna transcaucasica were carried out using 0.01% solution of colchicines and Phytohaemagglutinin (PHA) (20 µg g-1 body weight). The gill and kidney tissues were collected and let to stand in a hypotonic solution of 0.075 M KCl and then treated with a fixative (Carnoy's solution) in three steps. The chromosomes spreads were...

The main objective of the present study was to develop an efficient and reliable probe to be routinely used for detection of chromosome 13 copy numbers by interphase FISH. To achieve this, a Yeast Artificial Chromosome (YAC) containing sequences specific for human 13q12 (744D11), was cultured and the whole yeast genomic DNA was extracted. The human insert within the isolated DNA was amplified b...

This book is the outcome of a symposium on sulfur amino acids, held, by a Japanese research society, in Tokyo in 1982. The papers represent a multidisciplinary approach to biochemistry and biological actions of the sulfur amino acids. The book is divided into several sections. In the first section, the cardiovascular actions of the sulfur amino acids are considered. Although the title of the se...

Lantana species are an important component of the U.S. environmental horticulture industry. The most commonly produced and used L . camara and, on a smaller scale, montevidensis Both were introduced to United States from Central and/or South America. native continental include canescens , depressa involucrata etc. them have not been well exploited. This study was conducted obtain information ab...
