In cattle, retinoic acid (RA) has been indirectly associated with developmental potential of the embryo. RA is transported by retinol-binding protein (RBP) and actions of RA are mediated by several subtypes of nuclear retinoic acid receptors (RAR). Bovine embryos, produced in vitro from oocytes harvested from ovaries collected at a local abattoir, were(More)
The interactions of two economically important gall midge species, the rice gall midge and the Hessian fly, with their host plants, rice and wheat, respectively, are characterized by plant defense via R genes and insect adaptation via avr genes. The interaction of a third gall midge species, the orange wheat blossom midge, with wheat defense R genes has not(More)
In a hospital-based case-control study of 1441 patients with age-related cataracts and 549 controls, we studied associations between types of cataract--nuclear, cortical, posterior subcapsular, and mixed--and a number of physiologic, behavioral, environmental, and biochemical variables. Using polychotomous logistic regression analysis, we found an increased(More)
The effects of nonnutritive sucking (NNS) were studied in 40 preterm infants weighing less than or equal to 1800 g and of less than or equal to 35 weeks gestation by using a pacifier. The provision of NNS accelerated the maturation of sucking resulting in a faster transition from gavage to oral feedings. Treated infants (20) were ready for bottle feeds 1.54(More)
Intrauterine growth (weight, length, head circumference, Ponderal index) was studied in 2875 consecutive live born babies. Weight, length and head circumference growth curves did not show any significant difference when compared to previous growth curves made 20 years back from this centre. Norms and curves for ponderal index are provided for the Indian(More)
Using amplified fragment length polymorphisms (AFLPs) and random amplified polymorphic DNAs (RAPDs), we have tagged and mapped Gm8, a gene conferring resistance to the rice gall midge (Orseolia oryzae), a major insect pest of rice, onto rice chromosome 8. Using AFLPs, two fragments, AR257 and AS168, were identified that were linked to the resistant and(More)
Thirty mapped Indica rice genomic (RG) clones were partially sequenced from each end. From such sequence data, pairs of oligonucleotides were synthesized to act as primers for polymerase chain reaction (PCR) amplification of the corresponding loci in crude total DNA preparations. The PCR products from DNA of Indica varieties were of the sizes expected from(More)
In cattle, administration of retinol at the time of superovulation has been indirectly associated with enhanced developmental potential of the embryo. Vitamin A and its metabolites influence several developmental processes by interacting with 2 different types of nuclear receptors, retinoic acid receptors and retinoid X receptors (RXRs). Given the limited(More)
The chalcone synthase is a key enzyme that catalyses the first dedicated reaction of the flavonoid pathway in higher plants. The chs gene and its protein product in rice has been investigated. The presence of a chalcone synthase (CHS) protein in rice seedlings and its developmental stage-specific expression has been demonstrated by western analysis. The(More)
CONTEXT Acute lower respiratory tract infections (ALRI), ranked as the second leading cause of death are the primary cause of hospitalisation in children. Viruses are the most important causative agents of ALRI. AIM To study the viral aetiology of ALRI in children at a tertiary care hospital. SETTING AND DESIGN One year prospective observational study(More)
