BACKGROUND In developing countries, 80% of the births take place in the community. METHODS Birthweight, mid-arm and chest circumferences were measured in 294 newborns admitted in a tertiary-level hospital in Kolkata between April and August 2010. Colour-coded measuring tapes were devised using receiver operating characteristic curves to calculate the most(More)
BACKGROUND Despite the huge proportion of the babies in the developing world being born low birthweight, only about half of the newborns are weighed at birth as weighing scales often tend to be either non-available or defective. OBJECTIVE Designing a nomogram for estimation of birthweight from head circumference (HC) and mid-upper arm circumference(More)
STUDY OBJECTIVES The gold-standard test used to diagnose childhood obstructive sleep apnea is polysomnography. However, this test requires an overnight stay at a sleep laboratory and the attachment of multiple sensors to the patient. The long-term impact of this testing on the child and family are not known. We hypothesized that polysomnography does not(More)
Lung cancer is the leading cause of cancer- related death in the world today. Since the effective management of drug resistant lung cancer, and particularly non-small cell lung carcinomas is a major problem, attempts need to be made to identify new potential anticancer drugs that can kill non-small cell lung cancer cells efficiently. In the present study, a(More)
Fever, headache, body aches, retro-orbital pain, haemorrhage and shock are well known manifestations of dengue infection. We report the case of a 4-y-old child with dengue who presented with meningo-encephalitis and subsequently developed myelitis, hepatitis, glomerulonephritis and bone marrow suppression. Complete recovery occurred within 3 weeks.
Monolayer and agar culture techniques were used to examine the antiproliferative activities and morphological alterations of glioblastoma-astrocytoma (G1-As-14) cells induced by 20 mumol retinoic acid (RA). RA treated cells assumed flattened appearance and formed multilayers no longer. Most of the cells formed cross-bridges with one another. RA treatment(More)
Non-trypsinized primary fibroblast cells from 20-day-old Swiss mouse embryo was transformed by 20-methylcholanthrene (MCA) and was designated as CNCI-PM-20. The progressive development of some transformation related characters such as morphological alterations, reduced population doubling time, increased saturation density, reduced serum requirement,(More)
OBJECTIVES To assess the role of different factors that are associated with initiation and continuation of adolescent smoking. MATERIALS AND METHODS A total of 2535 students (1465 males and 1070 females) between the age groups of 14 and 19 years were selected from four schools and two colleges of the city by two-stage cluster sampling design for this(More)
Some major transformation related biological and growth properties have been analysed in an in vitro, system to characterize the PMM-14 cell line, a 20-methylcholanthrene induced transformed mouse embryonic fibroblast cell line. The population doubling time of this cell line was 19 h with moderately high saturation density and plating efficiency. Attachment(More)
Some biological properties related to transformation have been studied to characterize a spontaneously transformed mouse embryonic fibroblast cell line, PMS-14. Low population doubling time with moderately high plating efficiency and saturation density were noted. These cells showed reduced adhesion to substratum, enhanced agglutinability by concanavalin A,(More)
