Inference of ancestry from genetic data is a fundamental problem in computational genetics, with wide applications in human genetics and population genetics. The treatment of ancestry as a continuum instead of a categorical trait has been recently advocated in the literature. Particularly, it was shown that a European individual’s geographic coordinates of origin can be determined up to a few h...

We reviewed original articles in the field of pulmonary medicine that had been recently published in 12 Brazilian journals--general or specialty journals--excluding the Brazilian Journal of Pulmonology. All were journals indexed for the Institute for Scientific Information Web of Knowledge. The selection of articles was based on the "continuously variable rating" concept. We have organized the ...

when i first met this nice lady, i was in an evening work shift of ccu. this 69 years-old woman had been referred recently to our ward. she had a pale and puffy face. she suffered from chf. she had a normal breathing, but her ankle was swollen.   we stabilized her condition easily but, it was just the first step in her treatment way. prevention of recurrence of heart attack was our goal. every ...

second. The other ciliates studied obviously have a much lower speed of coordinating impulse. These values are so far below the velocities of true neural impulses that it is not possible to consider a "neuromotor" factor in the coordination of these Protozoa. Further investigations are in progress along the lines indicated here and will be reported in detail. The writer is indebted to Dr. W. M....

Duplogs, or intraspecies paralogs, constitute the important portion of eukaryote genomes and serve as a major source of functional innovation. We conducted detailed analyses of recently emerged animal duplogs. Genome data of three vertebrate species (Homo sapiens, Mus musculus, and Danio rerio), Caenorhabditis elegans, and two Drosophila species (Drosophila melanogaster and D. pseudoobscura) we...

It is well known that competitive analysis yields results that do not reflect the observed performance of online paging algorithms. Many deterministic paging algorithms achieve the same competitive ratio, ranging from inefficient strategies as flush-when-full to the well-performing leastrecently-used (LRU). In this paper, we study this fundamental online problem from the viewpoint of stochastic...

Several papers are discussed including the CARP (Coronary Artery Revascularisation Prophylaxis) trial, examining the role, if any, of preoperative coronary revascularisation and a study examining the heart rate in the intensive care unit (ICU) population. We also take a look at infections in the ICU with particular regard to a recent study which examined isolating patients with methicillin-resi...

A classification for advanced alveolar bone loss in children and adolescents is presented for the purpose of clarifying the oftentimes confusing terminology that presently exists. Page’s definiton of prepubertal periodontitis is advocated, and a representative case is presented. The classic definition of periodontosis is "a disease of the periodontium occurring in an otherwise healthy adolescen...

Studies of fetal hemoglobin and bone marrow ultrastructure were performed on a patient with a recently described syndrome consisting of lymphosarcoma, short stature, defective cellular Immunity, hypogammaglobulinemia, and mosaicism for a marker chromosome. Abnormalities of the erythroid cells, including multinucleated erythroblasts, nuclear bodies, megaloblasts, and frayed cytoplasm, were seen ...
