Tamilnadu is known for domestication of farm animals and home of many recognized sheep breeds, among them, Ramnad white is one of the breed of hardy and best suitable for the migratory system of rearing which were declining due to cross breeding. To retain the indigenous breed, many assisted reproduction technologies were used, but most of them are failed due to the detection of accurate estrus...

Ferns and lycophytes are the second third largest lineages of vascular plants, yet our understanding their interactions with phytophagous insects is very limited. In this study, we reviewed herbivorous insects, feeding habits host preferences on these two plant groups, searched for any evidence coevolution, discussed possible biases current knowledge fern–insect interactions. We analyzed 2318 r...

OBJECTIVE Accurate and timely diagnosis of rupture of membranes (ROM) is imperative to allow for gestational age-specific interventions. This study compared the diagnostic performance characteristics between two methods used for the detection of ROM as measured in the same patient. METHODS Vaginal secretions were evaluated using the conventional fern test as well as a point-of-care monoclonal...

Impacts of plant invasions are largely scale-dependent and responses to the same exotic species may vary among communities. Since impacts caused by individual trees could anticipate consequences of a closed canopy of an invader, we studied the response of Galápagos native plants to quinine (Cinchona pubescens) trees in two vegetation zones. Quinine has invaded >11,000 ha of Santa Cruz Island, i...

In a recent paper Gonz alez Manteiga and Vilar Fern andez (1995) considered the problem of testing linearity of a regression under MA(1) structure of the errors using a weighted L2-distance between a parametric and a nonparametric t. They established asymptotic normality of the corresponding test statistic under the hypothesis and under local alternatives. In the present paper we extend these r...

PROBLEM BEING ADDRESSED Traditional continuing medical education (CME) approaches do not work well in changing physicians' behaviour, but some promising strategies and technologies might help. Our program sought to meld small-group learning with an Internet e-mail approach. OBJECTIVE OF PROGRAM In 1994, the Family medicine Education and Research Network (FERN) was developed to support on-line...

Endophytic bacteria associated with the fern Dicksonia sellowiana were investigated. The bacterial communities from the surface-sterilized pinnae and rachis segments of the plants from the Brazilian Atlantic Rainforest that grew in native field conditions were compared with the bacterial communities from plants grown in greenhouses and plants that were initially grown in greenhouses and then tr...

The phytohormones cytokinin and auxin orchestrate the root meristem development in angiosperms by determining embryonic bipolarity. Ferns, having the most basal euphyllophyte root, form neither bipolar embryos nor permanent embryonic primary roots but rather an adventitious root system. This raises the questions of how auxin and cytokinin govern fern root system architecture and whether this ca...

The chloroplast gene trnK and its associated group II intron appear to be absent in a large and ancient clade that includes nearly 90% of fern species. However, the maturase protein encoded within the intron (matK) is still present and located on the boundary of a large-scale inversion. We surveyed the chloroplast genome sequence of clade-member Adiantum capillus-veneris for evidence of a still...
