Definition: Genetic engineering, recombinant DNA technology and biotechnology – the buzz words you may have heard often on radio or TV, or read about in featured articles in newspapers or popular magazines. It is a set of techniques that are used to achieve one or more of three goals: to reveal the complex processes of how genes are inherited and expressed, to provide better understanding and e...

Although tissue regeneration has been studied in a variety of organisms, from Hydra to humans, many of the genes that regulate the ability of each animal to regenerate remain unknown. The larval imaginal discs of the genetically tractable model organism Drosophila melanogaster have complex patterning, wellcharacterized development and a high regenerative capacity, and are thus an excellent mode...

Objectives. To compare the effectiveness of postcesarean thromboprophylaxis with two different regimens of bemiparin. Material and Methods. The study included 646 women with cesarean delivery in our hospital within a 1-year period, randomly assigned to one of two groups for prophylaxis with 3500 IU bemiparin once daily for 5 days or 3500 IU bemiparin once daily for 10 days. Results. There was o...

The mining industry is highly suitable for the application of robotics and automation technology, since the work is arduous, dangerous, and often repetitive. This paper presents a broad overview of the issues involved in the development of a physically large and complex field robotic system—a 3500-tonne mining machine (dragline). Draglines are “walking cranes” used in open-pit coal mining to re...

Promastigote forms of Phytomonas serpens, Leptomonas samueli, and Leishmania tarentolae express cytoskeletal giant proteins with apparent molecular masses of 3,500 kDa (Ps 3500), 2,500 kDa (Ls 2500), and 1,200 kDa (Lt 1200), respectively. Polyclonal antibodies to Lt 1200 and to Ps 3500 specifically recognize similar polypeptides of the same genera of parasite. In addition to reacting with giant...

BACKGROUND Cerebral blood flow velocity (CBFV) and sleep physiology in healthy children exposed to hypoxia and hypocarbia are under-researched. AIM To investigate associations between sleep variables, daytime end-tidal carbon dioxide (EtCO2) and CBFV in children during high-altitude ascent. METHODS Vital signs, overnight cardiorespiratory sleep studies and transcranial Doppler were undertak...

OBJECTIVE To compare the relation of birth weight with socioeconomic status measured by an area-based measure of material deprivation and by the Registrar General's social class. SETTING West Midlands Health Region 1991-93. STUDY DESIGN Retrospective cohort study. METHOD Birthweight data by enumeration district deciles ranked by Townsend Deprivation Index based on 1991 census data for all...
