Available in PDF, EPUB and Kindle. Book excerpt: HIV-1 associated neurocognitive disorders (HAND) remain a significant problem worldwide and can range in severity from disabling dementia to asymptomatic cognitive, motor and behavioral changes. Clinical assessments are the gold standard for detecting impairment and have defined the scope and severity of HAND; however, the viral determinants of HAND are not well understood. To further characterize the viral determinants of HAND, we studied viral evolution and disease by analyzing HIV-1 RNA extracted from blood and CSF samples along with participant specific clinical and neuropsychological assessments. HIV-1 RNA was amplified with Polymerase Chain Reaction (PCR) and sequenced using the Sanger Method. Neuropsychological assessments were administered and scored by trained psychometrists and included seven ability domains: learning, delayed recall, verbal fluency, processing speed, attention/working memory, abstraction/executive functioning and motor speed. HIV-1 population diversity was positively associated with disease, specifically AIDS and neuropsychological impairment. Further, antiretroviral resistance was associated with lower CSF viral loads and with better neuropsychological performance. Our findings suggest that HIV-1 virulence is most likely associated with the capacity of a viral population to maintain genetic diversity and not simply a specific and predominant genotypic variant. Although, the exact underlying mechanism for this remains unclear, complex phenotypes such as neuropsychological impairment may result from different HIV-1 variants operating in a coordinated manner to cause disease.

Download or read book Genomic Disorders written by James R. Lupski and published by Springer Science & Business Media. This book was released on 2007-11-10 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: A grand summary and synthesis of the tremendous amount of data now available in the post genomic era on the structural features, architecture, and evolution of the human genome. The authors demonstrate how such architectural features may be important to both evolution and to explaining the susceptibility to those DNA rearrangements associated with disease. Technologies to assay for such structural variation of the human genome and to model genomic disorders in mice are also presented. Two appendices detail the genomic disorders, providing genomic features at the locus undergoing rearrangement, their clinical features, and frequency of detection.

Available in PDF, EPUB and Kindle. Book excerpt: Recent neuroscience research makes it clear that human biology is cultural biology - we develop and live our lives in socially constructed worlds that vary widely in their structure values, and institutions. This integrative volume brings together interdisciplinary perspectives from the human, social, and biological sciences to explore culture, mind, and brain interactions and their impact on personal and societal issues. Contributors provide a fresh look at emerging concepts, models, and applications of the co-constitution of culture, mind, and brain. Chapters survey the latest theoretical and methodological insights alongside the challenges in this area, and describe how these new ideas are being applied in the sciences, humanities, arts, mental health, and everyday life. Readers will gain new appreciation of the ways in which our unique biology and cultural diversity shape behavior and experience, and our ongoing adaptation to a constantly changing world.
Download or read book Trinucleotide Repeat Protocols written by Yoshinori Kohwi and published by Springer Science & Business Media. This book was released on 2008-02-03 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trinucleotide repeats are relatively common in the human genome. These simple repeats have received much attention since epoch-making discoveries were made that particular trinucleotide repeats are expanded in the causal genes of human hereditary neurological disorders. For example, the CGG repeat is expanded in fragile X syndrome at the 5' untranslated region (UTR) of its causal gene. In myotonic dystrophy, it is the CTG repeat that is expanded at the 3' UTR of its causal gene. The CAG repeat was also found expanded in coding regions of the genes responsible for X-linked spinal and bulbar muscular atrophy, Huntington’s disease, spinocerebellar ataxia, and other disorders. On the other hand, expansion of the GAA repeat was identified in the intron of the gene responsible for the Friedreich’s ataxia. For these trinucleotide repeat diseases, the longer the trinucleotide expansion, the earlier the age of onset and the more severe the syndrome. Thus, these findings that showed the intriguing link between a particular trinucleotide expansion and its associated neurological disorders have led to a new field of intensive study. Active research addressing the underlying mechanisms for trinucleotide repeat diseases has employed various approaches ranging from DNA biochemistry to animal models for the diseases. In particular, animal models for the triplet repeat diseases have provided excellent resources not only for understanding the mechanisms but also for exploring therapeutic interventions.

Download or read book The Symbolic Species The Co evolution of Language and the Brain written by Terrence W. Deacon and published by W. W. Norton & Company. This book was released on 1998-04-17 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A work of enormous breadth, likely to pleasantly surprise both general readers and experts."—New York Times Book Review This revolutionary book provides fresh answers to long-standing questions of human origins and consciousness. Drawing on his breakthrough research in comparative neuroscience, Terrence Deacon offers a wealth of insights into the significance of symbolic thinking: from the co-evolutionary exchange between language and brains over two million years of hominid evolution to the ethical repercussions that followed man's newfound access to other people's thoughts and emotions. Informing these insights is a new understanding of how Darwinian processes underlie the brain's development and function as well as its evolution. In contrast to much contemporary neuroscience that treats the brain as no more or less than a computer, Deacon provides a new clarity of vision into the mechanism of mind. It injects a renewed sense of adventure into the experience of being human.
