abstract background a vast variety of factors may cause recurrent pregnancy loss. blood group incompatibility of parents could cause abortion. the examination of couples or twins, blood groups showed that the blood group incompatibility can affect adversely the outcome of pregnancy. couples with blood group incompatibility are more involved in spontaneous miscarriage. antigenes in two different...

OBJECTIVE To study detail microscopic evaluation and physiochemical analysis of Dillenia indica (D. indica) leaf. METHODS Fresh leaf sample and dried power of the leaf were studied macroscopically and microscopically. Preliminary phytochemical investigation of plant material was done. Other WHO recommended parameters for standardizations were also performed. RESULTS The detail microscopy re...

background & aim:   changes in lifestyle, decrease in physical exercise along with incidence of obesity, hypertension and cardiovascular diseases indicate a need for low calorie formulations. the sweetness of stevia, a natural sweetener, is estimated to be 300 times as much as that of sugar. extraction of stevia leaves is considered a promoter of calorie balance and a beneficial part of a h...

Bispecific antibodies show great promise as intrinsic combination therapies, but often suffer from poor physiochemical properties, many times related to poor heterodimerization. De Nardis et al. identify specific electrostatic interactions that facilitate efficient heterodimerization, resulting in bispecific antibodies with physiochemical properties very similar to those of naturally occurring ...

Disruption of interactions among ensembles of epistatic loci has been shown to contribute to reproductive isolation among various animal and plant species. Under the Bateson-Dobzhansky-Muller model, such interspecific incompatibility arises as a by-product of genetic divergence in each species, and the Orr-Turelli model indicates that the number of loci involved in incompatible interactions may...

The ability of a number of prediction systems was examined to determine how well they could predict Salmonella mutagenicity. The prediction systems included two computer-based systems (CASE and TOPKAT), the measurement of a physiochemical parameter (ke) and the use of structural alerts by an expert chemist. The computer-based systems operators and the chemist were supplied with the structures o...

Peptide and protein sequences are most commonly represented as a strings: a series of letters selected from the twenty character alphabet of abbreviations for the naturally occurring amino acids. Here, we experiment with representations of small peptide sequences that incorporate more physiochemical information. Specifically, we develop three different physiochemical representations for a set o...

Elvitegravir is a new-generation drug which acts as an integrase inhibitor of the HIV virus. The potential inhibition has been tested from the clinical trial data. Here the work basically deals with the quantitative structure-activity relationship (QSAR) analysis by considering some of the physiochemical descriptors like molecular weight, logP, molar volume, and structural descriptors like Wine...

Recent genetic analyses have demonstrated that self-incompatibility in flowering plants derives from the coordinated expression of a system of loci. To address the selective mechanisms through which a genetic system of this kind evolves, I present a three-locus model for the origin of gametophytic self-incompatibility. Conventional models assume that a single locus encodes all physiological eff...

BACKGROUND AND AIMS Heterostyly is a floral polymorphism characterized by the reciprocal position of stamens and stigmas in different flower morphs in a population. This reciprocal herkogamy is usually associated with an incompatibility system that prevents selfing and intra-morph fertilization, termed a heteromorphic incompatibility system. In different evolutionary models explaining heterosty...
