PineElm_SSRdb: a microsatellite marker database identified from genomic, chloroplast, mitochondrial and EST sequences of pineapple ( (L.) Merrill).

Background: Simple Sequence Repeats or microsatellites are resourceful molecular genetic markers. There are only few reports of SSR identification and development in pineapple. Complete genome sequence of pineapple available in the public domain can be used to develop numerous novel SSRs.

Incomplete Cantrell's Pentalogy-A Case Report.

We present a case of an 11-year-old boy, who presented to us with a ventral hernia since birth. He was found to have the following: A large ventral midline defect starting from umbilicus to xiphisternum. Sternum was bifid at the lower end.

Gene duplication as a major force in evolution.

Gene duplication is an important mechanism for acquiring new genes and creating genetic novelty in organisms. Many new gene functions have evolved through gene duplication and it has contributed tremendously to the evolution of developmental programmes in various organisms. Gene duplication can result from unequal crossing over, retroposition or chromosomal (or genome) duplication.

Proboscis lateralis of nose-a case report.

Lateral proboscis is a rare craniofacial malformation characterized by a rudimentary tubular, nose-like structure located off-center from the vertical midline of the face, and occur in association with a wide spectrum of other anomalies, including heminasal aplasia spectrum,mental retardation, callosal agenesis, heminasal hypoplasia, microphthalmia, and atypical clefting syndrome. Evaluation of a patient should include CT scan examination to look for growth of facial and skull bones. Reconstruction should start at an early age.

Electron donor-acceptor interaction of 3,4-dimethylaniline with 2,3-dicyano-1,4-naphthoquinone.

The electron donor-acceptor (EDA) interaction between 2,3-dicyano-1,4-naphthoquinone (DCNQ) and 3,4-dimethylaniline (3,4-DMA) is studied in chloroform, dichloromethane and 1:1 (v/v) mixture of chloroform and dichloromethane. The rate of formation of the product was measured as a function of time using UV-vis spectrophotometer. The formation constant (K) and molar extinction coefficient (ɛ) values for the formation of EDA complex were evaluated in the temperature range of 20-35°C.
