Microbiology's scarred revolutionary.
نویسنده
چکیده
Microbial biology is undergoing a renaissance, and in this special section we explore bursts of progress in areas ranging from how pathogens invade cells to the origins of life. News reports beginning on this page focus on the extremophiles--unusual microbes that flourish in harsh conditions--while the Articles that follow probe a broad range of topics, including plant-microbe interactions and the astonishing diversity of microbes.

There must be a prokaryote somewhere: microbiology's search for itself.
While early microbiologists showed considerable interest in the problem of the natural (evolutionary) relationships among prokaryotes, by the middle of this century that problem had largely been discarded as being unsolvable. In other words, the science of microbiology developed without an evolutionary framework, the lack of which kept it a weak discipline, defined largely by external forces. M...
متن کاملFrequency of placenta previa in previously scarred and non scarred uterus
OBJECTIVE To determine the frequency of placenta Previa in patients coming to a tertiary care unit with previously scarred and non-scarred uterus. METHODS A descriptive cross sectional study was carried on 114 cases who underwent caesarean sections (37 cases out of 645 cases with non scarred uterus and 77 cases from 721 cases with scarred uterus) in the department of obstetrics and gynecology...
متن کاملProbability mapping of scarred myocardium using texture and intensity features in CMR images
BACKGROUND The myocardium exhibits heterogeneous nature due to scarring after Myocardial Infarction (MI). In Cardiac Magnetic Resonance (CMR) imaging, Late Gadolinium (LG) contrast agent enhances the intensity of scarred area in the myocardium. METHODS In this paper, we propose a probability mapping technique using Texture and Intensity features to describe heterogeneous nature of the scarred...
متن کاملImaging in urinary tract infection.
The relationship of vesicoureteric reflex (VUR) and renal scarring was studied in 94 children (188 kidneys) with proved urinary tract infection in a district general hospital. There were 61 girls and 33 boys, with nine girls and 17 boys aged less than 1 year, 31 girls and nine boys aged between 1 and 5 years, the remaining 28 children were over 5 years of age. All children had a micturating cys...
متن کاملPathological Mechanism for Delayed Hyperenhancement of Chronic Scarred Myocardium in Contrast Agent Enhanced Magnetic Resonance Imaging
OBJECTIVES To evaluate possible mechanism for delayed hyperenhancement of scarred myocardium by investigating the relationship of contrast agent (CA) first pass and delayed enhancement patterns with histopathological changes. MATERIALS AND METHODS Eighteen pigs underwent 4 weeks ligation of 1 or 2 diagonal coronary arteries to induce chronic infarction. The hearts were then removed and perfus...
