Ficus exasperata is a plant used in the traditional management of malaria in south-south Nigeria. An investigation into the effects of the ethanolic extract of the leaf of the plant on some biochemical indices in albino mice infected with Plasmodium berghei (NK 65) was conducted. 48 mice with weight range of 13-23 g were grouped into six (A, B, C, D, E, and F). Each group contained 8 mice. Grou...

Varroosis, a disease caused by the mite Varroa destructor Anderson and Treuman has killed hundreds of thousands of Apis mellifera L. colonies in various parts of the world. Nevertheless, the damage caused by this mite varies with the type of bee and climate conditions. Varroa causes little damage to Africanized bee colonies in Brazil, as the infestation rates are relatively stable and low. We e...

394 CLINICAL CHEMISTRY, Vol. 29, No. 2, 1983 logarithmic but biphasic in nature. The biological half-life of the drug was shorter 124 h if estimated by visual inspection; 13 h if estimated by the method of residuals (1)1 during the first two days, longer (52 h) for the following three days (Figure 1). At therapeutic concentration in plasma, digoxin enters the elimination (/3) phase from the dis...

Candidates for medical school are encouraged to investigate their chosen career by spending time in general practice prior to applying to university. To investigate the prevalence and nature of this practice I surveyed first year medical students at the University of Leeds during introductory week. The response rate to an initial questionnaire was 63% (135 students). Of these, 59% (79) had spen...

27 In vertebrates, acute stressors, although short in duration, can influence physiology and behavior 28 over a longer time course, which might have important ramifications under natural conditions. In 29 laboratory rats, for example, acute stress has been shown to increase anxiogenic behaviors for days 30 after a stressor. In the present study, we quantified voluntary wheel-running behavior fo...

To determine the risk of secondary poisoning for animals preying on sub-lethally poisoned brushtail possums, captive possums were treated with near-lethal doses of sodium monofluoroacetate (1080) or brodifacoum, and toxicant concentrations in blood and tissue were monitored over time. Sodium monofluoroacetate was rapidly eliminated from the blood (within three days). Brodifacoum was retained in...

Background: The prognostic importance of dyskinesia after acute myocardial infarction is unknown, and recommendations have been made that dyskinesia be included in calculations of wall motion index (WMI). Objective: To determine whether it is necessary to distinguish between dyskinesia and akinesia when WMI is estimated for prognostic purposes following acute myocardial infarction. Design: Mult...

The purpose of this research study was to determine whether or not visual function of baseball players would be improved by specifi c training. A total Forty-four male baseball players (age: 20.7±1.4, athletic career: 11.0±2.5 years) voluntarily participated in this study. The sample subjects were divided into three groups : Experimental group I, Experimental group II, and Control group. Sample...

Radio tracking of 40 free-ranging eastern brownsnakes (Pseudonaja textilis) in an agricultural landscape in southeastern Australia clarified the spatial ecology of these highly venomous animals. Most snakes over-wintered in burrows within a small area on the bank of an irrigation canal, dispersing into agricultural land during the warmer months. The snakes sheltered overnight in burrows or soil...

We propose a novel, large-scale, structure-from-motion framework that advances the state of the art in data scalability from city-scale modeling (millions of images) to world-scale modeling (several tens of millions of images) using just a single computer. The main enabling technology is the use of a streaming-based framework for connected component discovery. Moreover, our system employs an ad...
