Analysis of the mechanisms underlying cardiac excitability can be facilitated greatly by mutations that disrupt ion channels and receptors involved in this excitability. With an extensive repertoire of such mutations, Drosophila provides the best available genetic model for these studies. However, the use of Drosophila for this purpose has been severely(More)
Wear debris from metal on polyethylene joint replacements causes asceptic loosening as a result of an inflammatory reaction of macrophages to micron-sized particles. Metal on metal implants, which generate nanoparticles, have been reintroduced into surgical practise in order to avoid this problem. There is a current concern about possible long-term effects(More)
CONTEXT Adolescent pregnancy occurs in all societies, but the level of teenage pregnancy and childbearing varies from country to country. A cross-country analysis of birth and abortion measures is valuable for understanding trends, for identifying countries that are exceptional and for seeing where further in-depth studies are needed to understand observed(More)
Honokiol (3',5-di-(2-propenyl)-1,1'-biphenyl-2,4'-diol) is a bioactive natural product derived from Magnolia spp. Recent studies have demonstrated anti-inflammatory, anti-angiogenic, anti-oxidative and anticancer properties of honokiol in vitro and in preclinical models. Honokiol targets multiple signaling pathways including nuclear factor kappa B (NF-κB),(More)
The delayed rectifier potassium current plays a critical role in cellular physiology. This current (I(K)) in Drosophila larvae is believed to be a single current. However, a likely null mutation in the Shab K(+) channel gene (Shab(3)) reduces I(K) but does not eliminate it. This raises a question as to whether or not the entire I(K) passes through channels(More)
Voltage-dependent calcium channels play a role in many cellular phenomena. Very little is known about Ca2+ channels in Drosophila, especially those in muscles. Existing literature on neuronal Ca2+ channels of Drosophila suggests that their pharmacology may be distinct from that of vertebrate Ca2+ channels. This raises questions on the pharmacology and(More)
The distribution of the human liver alcohol dehydrogenase, ADH2, and aldehyde dehydrogenase, ALDH2, genotypes in 21 different populations comprising Mongoloids, Caucasoids, and Negroids was determined by hybridization of the amplified genomic DNA with allele-specific oligonucleotide probes. Whereas the frequency of the ADH1(2) allele was found to be(More)
CONTEXT Adolescent pregnancy, birth, abortion and sexually transmitted disease (STD) rates are much higher in the United States than in most other developed countries. METHODS Government statistics or nationally representative survey data were supplemented with data collected by private organizations or for regional or local populations to conduct studies(More)
BACKGROUND Given the constraints of resources, thrombolysis for acute ischemic stroke (AIS) is under evaluation in developing countries. Prothrombin time (PT), platelet count and activated partial thromboplastin time (aPTT) may not be feasible within the time window. AIM To evaluate the safety and efficacy of thrombolysis in selected patients without the(More)
BACKGROUND Interpretation of thyroid function tests during pregnancy needs trimester-related reference intervals from pregnant populations with minimal risk for thyroid dysfunction. While India has become iodine sufficient after two decades of salt iodisation, there is no normative data for thyroid function from healthy pregnant women of this country. (More)
