The role of the musical intelligence in whole brain education

This study was prompted by the recent increase in academic and public interest in neuromusical brain research, which provides information about how the brain processes music. It is the task of neural science to explain how the individual units of the brain are used to control behaviour, and how the functioning of these units is influenced by an individual's specific environment and relationships with other people. However, the concept of neuromusical research is relatively new to music education. In any learning experience, brain processing (of information) is not an end in itself. The skill of 'thinking' is dependent on the whole integrated mind/body system, with skills being a manifestation of conscious physical responses that demonstrate knowledge acquisition. Howard Gardner's 'Theory of Multiple Intelligences' lists the musical intelligence as one of eight autonomous intelligences: linguistic, logic-mathematical, spatial, bodily-kinesthetic, musical, intrapersonal, interpersonal, and environmental. All of these intelligences can be developed to a reasonably high level. This thesis uses David Elliott's praxial philosophy as a conceptual basis. Elliott's four meanings of music education: education in music, by music, for music, and by means of music, have been selected to determine the parameters for an 'inclusive' understanding of musical intelligence. Scientific research findings, brain based data, and behavioural results with educational implications have been used to define what is meant by the musical intelligence, and its role in whole brain learning. Whole brain learning (also referred to as 'accelerated' learning or 'super' learning) is examined in the framwork of IQ (intellectual quotient/intelligence), EQ (emotional intelligence), and SQ (spiritual intelligence). It is important to note that the brain imposes certain constraints on the learning ability of individuals, but that there are also numerous benefits to be derived from an awarenss of brain functions pertaining to education in general and music education in particular. These constraints and benefits are an important feature of whole brain learning, with the musical intelligence playing a vital role.Dissertation (DMus)--University of Pretoria, 2003.Musicunrestricte

Developing the pre-school child's musical intelligence by means of a comprehensive music programme focused on age-controlled auditive development

Because music is sound, the development of the young child's musical intelligence is integrally linked to his/her auditive development. By neglecting to develop the child's musical intelligence, and in particular by neglecting the age-controlled auditive development of the young child, essential learning stages may be missed. It is therefore encouraging that the government has stated its intention to introduce a compulsory reseption year (Grade 0) for five to six year old children. There is, however, at present no comprehensive pre-school music education programme available which specifically focuses on the auditive development of the child in the process of developing his/her musical intelligence. In this study, a comprehensive music education programme based on the praxial philosophy of music education has been compiled. It promotes procedural knowledge (making music), without negating propositional knowledge (knowing about music). It is hoped that the study will assist the class teacher as well as the music specialist as they strive to develop the musical intelligences of South Africa's pre-school children.Thesis (MMus)--University of Pretoria, 2004.Musicunrestricte

Mutations in Ribonucleic Acid Binding Protein Gene Cause Familial Dilated Cardiomyopathy

ObjectivesWe sought to identify a novel gene for dilated cardiomyopathy (DCM).BackgroundDCM is a heritable, genetically heterogeneous disorder that remains idiopathic in the majority of patients. Familial cases provide an opportunity to discover unsuspected molecular bases of DCM, enabling pre-clinical risk detection.MethodsTwo large families with autosomal-dominant DCM were studied. Genome-wide linkage analysis was used to identify a disease locus, followed by fine mapping and positional candidate gene sequencing. Mutation scanning was then performed in 278 unrelated subjects with idiopathic DCM, prospectively identified at the Mayo Clinic.ResultsOverlapping loci for DCM were independently mapped to chromosome 10q25-q26. Deoxyribonucleic acid sequencing of affected individuals in each family revealed distinct heterozygous missense mutations in exon 9 of RBM20, encoding ribonucleic acid (RNA) binding motif protein 20. Comprehensive coding sequence analyses identified missense mutations clustered within this same exon in 6 additional DCM families. Mutations segregated with DCM (peak composite logarithm of the odds score >11.49), were absent in 480 control samples, and altered residues within a highly conserved arginine/serine (RS)-rich region. Expression of RBM20 messenger RNA was confirmed in human heart tissue.ConclusionsOur findings establish RBM20as a DCM gene and reveal a mutation hotspot in the RS domain. RBM20is preferentially expressed in the heart and encodes motifs prototypical of spliceosome proteins that regulate alternative pre-messenger RNA splicing, thus implicating a functionally distinct gene in human cardiomyopathy. RBM20mutations are associated with young age at diagnosis, end-stage heart failure, and high mortality

Demonstration of vasoproliferative activity from mammalian retina

Vasoproliferative activity has been demonstrated in extracts of retinas from human, bovine, and feline sources. These retinal extracts are capable of stimulating (a) proliferation and thymidine uptake of bovine vascular endothelial cells in culture and (b) neovascularization on the chick chorioallantoic membrane. Extracts of skeletal muscle, cardiac muscle, and liver lack similar stimulatory activity. The activity is nondialyzable, stable at 56 degrees C, and inactivated at 100 degrees C. Retinal extracts stimulate the proliferation of corneal fibroblasts but have no effect on the proliferation of vascular smooth muscle cells. Indirect evidence suggests the liberation of a vasoproliferative factor from retina in several ocular disorders. The data in this report represent the first direct demonstration of vasoproliferative activity from mammalian retina

Histopathology of familial versus nonfamilial dilated cardiomyopathy

Idiopathic dilated cardiomyopathy is most likely a heterogenous group of diseases characterized by ventricular dilatation and dysfunction. Approximately 20% of patients with idiopathic dilated cardiomyopathy have familial disease, which may be inapparent by review of the family history alone. It has been suggested that histopathologic features, particularly the presence of bizarrely shaped mitochondria, may be useful in distinguishing familial from nonfamilial disease.We investigated 57 patients with dilated cardiomyopathy, 13 familial and 43nonfamilial or indeterminate. Pathologic examination of right endomyocardial biopsy specimens showed no significant differences between the familial, nonfamilial, or indeterminate groups by light microscopy or electron microscopy. We conclude that the distinction between familial and nonfamilial dilated cardiomyopathy cannot be made by histopathologic examination in most cases.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/30544/1/0000177.pd

The Drosophila 7SK snRNP and the essential role of dHEXIM in development

Regulation of the positive transcription elongation factor, P-TEFb, plays a major role in controlling mammalian transcription and this is accomplished in part by controlled release of P-TEFb from the 7SK snRNP that sequesters the kinase in an inactive state. We demonstrate here that a similar P-TEFb control system exists in Drosophila. We show that an RNA previously suggested to be a 7SK homolog is, in fact, associated with P-TEFb, through the action of a homolog of the human HEXIM1/2 proteins (dHEXIM). In addition, a Drosophila La related protein (now called dLARP7) is shown to be the functional homolog of human LARP7. The Drosophila 7SK snRNP (d7SK snRNP) responded to treatment of cells with P-TEFb inhibitors and to nuclease treatment of cell lysates by releasing P-TEFb. Supporting a critical role for the d7SK snRNP in Drosophila development, dLARP7 and dHEXIM were found to be ubiquitously expressed throughout embryos and tissues at all stages. Importantly, knockdown of dHEXIM was embryonic lethal, and reduction of dHEXIM in specific tissues led to serious developmental defects. Our results suggest that regulation of P-TEFb by the d7SK snRNP is essential for the growth and differentiation of tissues required during Drosophila development

Prognostic impact of vitamin B6 metabolism in lung cancer

Patients with non-small cell lung cancer (NSCLC) are routinely treated with cytotoxic agents such as cisplatin. Through a genome-wide siRNA-based screen, we identified vitamin B6 metabolism as a central regulator of cisplatin responses in vitro and in vivo. By aggravating a bioenergetic catastrophe that involves the depletion of intracellular glutathione, vitamin B6 exacerbates cisplatin-mediated DNA damage, thus sensitizing a large panel of cancer cell lines to apoptosis. Moreover, vitamin B6 sensitizes cancer cells to apoptosis induction by distinct types of physical and chemical stress, including multiple chemotherapeutics. This effect requires pyridoxal kinase (PDXK), the enzyme that generates the bioactive form of vitamin B6. In line with a general role of vitamin B6 in stress responses, low PDXK expression levels were found to be associated with poor disease outcome in two independent cohorts of patients with NSCLC. These results indicate that PDXK expression levels constitute a biomarker for risk stratification among patients with NSCLC.publishedVersio

Repositioning of the global epicentre of non-optimal cholesterol

High blood cholesterol is typically considered a feature of wealthy western countries(1,2). However, dietary and behavioural determinants of blood cholesterol are changing rapidly throughout the world(3) and countries are using lipid-lowering medications at varying rates. These changes can have distinct effects on the levels of high-density lipoprotein (HDL) cholesterol and non-HDL cholesterol, which have different effects on human health(4,5). However, the trends of HDL and non-HDL cholesterol levels over time have not been previously reported in a global analysis. Here we pooled 1,127 population-based studies that measured blood lipids in 102.6 million individuals aged 18 years and older to estimate trends from 1980 to 2018 in mean total, non-HDL and HDL cholesterol levels for 200 countries. Globally, there was little change in total or non-HDL cholesterol from 1980 to 2018. This was a net effect of increases in low- and middle-income countries, especially in east and southeast Asia, and decreases in high-income western countries, especially those in northwestern Europe, and in central and eastern Europe. As a result, countries with the highest level of non-HDL cholesterol-which is a marker of cardiovascular riskchanged from those in western Europe such as Belgium, Finland, Greenland, Iceland, Norway, Sweden, Switzerland and Malta in 1980 to those in Asia and the Pacific, such as Tokelau, Malaysia, The Philippines and Thailand. In 2017, high non-HDL cholesterol was responsible for an estimated 3.9 million (95% credible interval 3.7 million-4.2 million) worldwide deaths, half of which occurred in east, southeast and south Asia. The global repositioning of lipid-related risk, with non-optimal cholesterol shifting from a distinct feature of high-income countries in northwestern Europe, north America and Australasia to one that affects countries in east and southeast Asia and Oceania should motivate the use of population-based policies and personal interventions to improve nutrition and enhance access to treatment throughout the world.Peer reviewe
