Las barreras ocultas en la universidad
Authors: Durand Julio 
Published: February 2024

Mientras el mundo universitario celebra el centenario de la Reforma de 1918, comienzan a despuntar algunos temas con potencial para torcer la tendencia declinante que ha mostrado el sistema universitario argentino en los últimos 50 años, tras haber sido líder en calidad, alcance y cobertura. Muchos países de la región han sido capaces de cambiar el funcionamiento de sus instituciones universitarias, sin abandonar su identidad. Se modernizaron, adoptando las mejores prácticas y los sistemas de educación más innovadores, productivos e inclusivos del mundo.

Uno de los temas de mayor potencial reformador es el establecimiento de un sistema de reconocimiento y transferencia de los estudios realizados. Se conocen como sistemas de créditos, que el Gobierno ha decidido denominar RTF (reconocimiento de trayectos formativos). Hace años, Europa adoptó el sistema de transferencia de créditos, que resultó la herramienta práctica para que el "proceso de Bolonia" culminara exitosamente con la creación del Espacio Europeo de Educación Superior, y se generara una increíble dinámica estudiantil y académica.

Authors: TITILAYO SOJI-ONI  , ADESOJI.A. ONI  
Published: February 2024

Home factors entails the objects, materials, parents, siblings, peers and social life that exists in the home in which the students find himself/herself. All the variables in the home that affect a child’s existence, behaviour and performance constitute the home environmental factors, while student achievement refers to the extent to which a learner has attained their short or long-term educational goals. Individual differences in academic performance are strongly correlated with differences in personality and intelligence. The study examined the effects of home factors and students’ classroom participation on the academic performance of senior secondary schools in Lagos, Nigeria. Consequently, four research questions and three hypotheses were formulated to guide the study, the study was limited to Education District I, of Lagos, Nigeria. The study adopted the descriptive survey research design, using a self-constructed questionnaire to collect data from secondary school teachers and students. The validity of the instrument was done by experts in sociology of education and measurement and evaluation, while the researchers administered the instrument to 30 students not involved in the main sample for pilot testing. The reliability correlation coefficient index obtained was 0.78. The data collected were analysed using simple percentage, t-test, Chi-square and Pearson Product Moment Correlation Coefficient method of statistical analysis. These statistics were used to demonstrate whether the variables are correlated or related. The findings of the study revealed that students’ home factors affect their academic performance; teachers and the students have different perceptions of the relevance of home factors; and that a significant relationship exists between home factors and students’ classroom participation. The study therefore concluded and recommended that education should be mounted for parents in our formal and non-formal education programmes in order to educate parents on their roles as parents in the education of their wards

Authors: Jain Niyati , Sikarwar R. S. , Tripathi M. K. , Tiwari Sushma 
Published: February 2024

A study was conducted employing twelve quantitative traits viz., days to 50% flowering, days to maturity, plant height(cm), number of branches per plant, number of clusters per plant, number of pods per cluster, pod length(cm), number of seeds per pod, 100 seed weight(g), harvest index, biological yield per plant and seed yield per plant (g) on 40 green gram genotypes with the intent to uncover the genetic variability, heritability and genetic advance. Significant variance was found for each characteristic when using simple descriptive statistics. High PCV and GCV estimates was noticed for number of pods per plant, seed yield per plant, number of cluster per plant and number of pods per cluster. Days to 50% flowering, plant height, number of branches per plant, number of clusters per plant, number of pods per plant, pod length, number of seeds per pod, 100 seed weight, biological yield per plant and seed yield per plant showed high heritability with high genetic advancement based on a study of genetic variability, suggesting that additive gene action predominates. It will be beneficial to select for these traits.

Published: February 2024

The egg parasitoid, Trichogramma chilonis is a potential egg parasitoid in the sugarcane, reducing early shoot borer and internode borer population. The laboratory strains of T. chilonis was significantly inferior to the ecotypes collected from fields in their tolerance to insecticide due to continuous exposure to insecticides in the field. Hence, a study was undertaken to evaluate the laboratory reared strain of T. chilonis with that of other ecotypes to identify a pesticide tolerant ecotype for use in pest management by augmentative release. Five ecotypes of T. chilonis were collected from farmer's fields on sugarcane and citrus using sentinel egg technique by exposing egg cards of Corcyra cephalonica, mass reared on C. cephalonica for three successive generations and tested for their relative tolerance to insecticides in comparison with the laboratory strain. Significantly higher level of parasitisation (50.59, 45.32 and 60.45 %) by Arungunam ecotype was observed on eggs sprayed with Imidacloprid 70 WS, Thiomethoxam 75 SG and Flubendiamide 20% WG respectively before exposing to the parasitoid. The Chitteri ecotype was found next in order of tolerance to the insecticides Imidacloprid 70 WS, Thiomethoxam 75 SG and Flubendiamide 20% WG (45.00, 41.23 and 58.23 % respectively). The adult emergence was not found to be affected much by the insecticides sprayed before parasitisation. Varying degrees of insecticide toxicity against different ecotypes of T. chilonis inside host eggs was observed and Arungunam ecotype showed more tolerance to the insecticides tested with,71.28, 53.46 and 81.67 per cent adult emergence respectively from parasitised eggs sprayed with Imidacloprid 70 WS, Thiomethoxam 75 SG and Flubendiamide 20% WG. Among the insecticide tested, Flubendiamide was least toxic to the parasitoid developing with in the host egg and Thiomethoxam was found to be more toxic with nearly 50 per cent reduction in the adult emergence.
The genetic structure of human pathogens
Authors: Wilson Daniel J. , Falush Daniel 
Published: January 2005

Abstract

Human pathogen populations are structured by processes including within‐host competition, host–pathogen interaction, selection on the transmission cycle, historic changes in prevalence, and human migratory history. We document examples in which signatures of each process are evident and describe some of the factors that lead one process to dominate over the others. Intuitively, it might be thought that pathogen coevolutionary interaction is so intense that under normal circumstances we might expect that the signature of historic migration is obliterated. However, while this is the case for most pathogens, one pathogen,
Helicobacter pylori
, provides a signature of migrations, which seems, given current sequencing and analytical technologies, to be at least as informative as human genes.
Uniparental disomy
Authors: Theisen Aaron P. , Shaffer Lisa G. 
Published: January 2005

Abstract
Normal, biparental inheritance of the autosomal genes results from one member of each pair of homologous chromosomes being inherited from each parent. Originally proposed as a mechanism for human genetic disease in 1980, uniparental disomy is the abnormal inheritance of a pair of homologous chromosomes from a single parent. Uniparental disomy results in a chromosomally balanced offspring who, depending on the chromosome involved, may be phenotypically normal. However, for some chromosomes, uniparental disomy may result in over‐ or underexpression of imprinted genes, which exhibit parent‐of‐origin‐specific differences in expression. Numerous clinically significant syndromes, most involving differential growth and cognitive effects, are the consequence of imprinting effects unmasked by uniparental disomy.
Sex‐specific maps and consequences for linkage mapping
Authors: Sieberts Solveig K. , Gudbjartsson Daniel F. 
Published: January 2005

Abstract
In humans, as in most species, map distances vary between the sexes. Overall, the female‐to‐male ratio is estimated to be 1.65 : 1, but this ratio varies by chromosome. Additionally, ratios are not constant along the chromosome, and patterns of sex‐distance ratio vary by chromosome. Generally, females tend to demonstrate more recombination near the centromere, while males demonstrate more recombination near the telomeres. Despite the sometimes extreme differences between the sex‐specific maps, multipoint linkage analyses are often performed assuming a sex‐averaged linkage map. Assuming a sex‐averaged map can alter the distributions of the LOD, and NPL scores, and can affect the power and false‐positive rate, especially when pedigrees contain unequal numbers of male and female meioses or when specifically modeling parent‐of‐origin effects, such as imprinting models.

AbstractLinkage analysis has become the key tool for the identification of genetic factors causing human disorders. Methodology has been developed and continues to be developed to analyze linkage data for a variety of disease models and pedigree structures. We present detailed examples of three basic methods: parametric (for both dominant and recessive traits), affected sibling pair, and nonparametric linkage.
Ethical and legal issues in medical genetics
Authors: Pelias Mary Kay 
Published: January 2005

AbstractThe foundations of ethical and legal issues in medical genetics lie in the evolution of the physician–patient and researcher–subject relationships. As patients and subjects have acquired protection of their personal autonomy, parallel doctrines of informed consent have developed in clinical practice and biomedical research. Issues of genetic testing in children, newborn screening, and use of archived tissue samples have been widely studied and at least partially resolved. Issues derived from concerns about genetic privacy and nondiscrimination include questions about recontacting patients when new information becomes available and about a possible duty to warn relatives who are not patients but who might be at risk for a genetic disorder or disease. Confidentiality issues have arisen in policies and practices in the insurance industry and in providing safety and benefits in the workplace. Finally, new concerns about privacy, discrimination, and social stigmata arise in pharmacogenetics as researchers become more proficient at tailoring pharmaceuticals to particular racial and ethnic groups.
Artificial self‐assembling systems for gene therapy
Authors: Lehn Pierre 
Published: January 2005

Abstract
Over the last decade, a variety of nonviral systems have been developed as an alternative to recombinant viruses for gene delivery. The challenge nowadays is to design improved chemical vectors for more efficient in vivo transfection. Sophisticated multifunctional systems in which each component enables the DNA complex to overcome a critical cellular barrier may be the answer. Such “artificial viruses” may form clinically useful transfection vectors in the future.

Published: January 2005

Abstract
Molecular cytogenetic tools, whole‐chromosome paints in particular, have been extensively used to disclose changes that have shaped the karyotype organization of primates. In addition, detailed marker order arrangement defined by using appropriate BAC and PAC probes have revealed the relatively frequent occurrence of an unprecedented phenomenon: the centromere repositioning during evolution. Remains of evolutionary inactivated centromeres appears to play a key role in the emergence of neocentromeres in human clinical cases.
Comparative sequencing of vertebrate genomes
Authors: Portnoy Matthew E. , Green Eric D. 
Published: January 2005

Abstract
The areas of large‐scale DNA sequencing and sequence analysis are undergoing a rapid metamorphosis, as priorities shift from generating genome sequences for a select group of reference species to interpreting the information encoded therein. Comparison of the human genome sequence with that of other vertebrates has emerged as a critical component of this interpretative process. Newly developed experimental and computational methods are providing more powerful approaches for comparative sequence analyses, and in turn, these are being used for systematically unraveling the complexities of vertebrate genomes.
UsingORESTESESTsto mine gene cancer expression data
Authors: de Souza Sandro J. , Galante Pedro A.F. , Soares Rodrigo 
Published: January 2005

AbstractOne of the major challenges in bioinformatics is the development of tools and/or approaches that are able to mine the huge amount of data available in a manner that is effective and biologically meaningful. This is particularly important for cancer research, where public and private initiatives have produced cancer‐oriented databases that are to some degree complementary but not yet fully integrated. We will discuss in this review one type of expressed sequence, ORESTES sequences, that comprised the basis of the Ludwig/Fapesp Human Cancer Genome Project (HCGP). Furthermore, we will discuss different approaches used by several groups to mine ORESTES data, especially when integrated to other types of data in cancer.
Pilot gene discovery in plasmodial pathogens
Authors: Carlton Jane M. 
Published: January 2005

AbstractBefore the onset and completion of thePlasmodiumgenome sequencing projects, gene discovery in species of malaria parasite relied heavily upon pilot EST sequencing projects. Stage‐specific cDNA libraries were generated for several human and rodent model malaria parasite species, and partial sequencing of individual cDNA clones enabled the production of gene tags that could then be searched against public sequence databases for gene identification and annotation. A wealth of partial gene sequence data was generated and made available to the scientific community in order to jump‐start gene discovery and biological investigation. The importance of these efforts has been reemphasized recently with the publication of the genome sequences of twoPlasmodiumspecies that relied upon the EST data for training gene finder software and for gene model verification. The generation ofPlasmodiumEST data continues and provides invaluable gene expression data for use in a postgenomic world.
Two‐dimensional gel electrophoresis

Published: January 2005

Abstract

Two‐dimensional gel electrophoresis (2DE) with immobilized pH gradients (IPGs) combined with protein identification by mass spectrometry (MS) is currently the workhorse for proteomics. In spite of new promising technologies that have emerged (MudPIT, stable isotope labeling, arrays), 2DE is currently the only technique that can be routinely applied for parallel quantitative expression profiling of large sets of complex protein mixtures such as whole cell lysates. 2DE couples isoelectric focusing (IEF) and sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS‐PAGE) to resolve proteins according to two independent parameters, that is, isoelectric point (pI) in the first dimension and molecular mass (M
r
) in the second. 2DE can resolve more than 5000 proteins simultaneously (∼2000 proteins routinely), and can detect <1 ng of protein per spot. Furthermore, it delivers a map of intact proteins, which reflects changes in protein expression level, isoforms or posttranslational modifications. This is in contrast to LC‐MS/MS‐based methods, which perform analysis on peptides, where M
r
and pI information is lost. Whatever technology is used, proteome analysis is technically challenging, because the number of different proteins expressed at a given time under defined biological conditions is likely to be in the range of at least several thousand in total cell lysates. In this article, we describe the 2DE‐MS workflow including the following topics: Sample preparation/solubilization, protein separation by 2DE with IPGs, protein detection and quantitation, computer‐assisted analysis of 2DE patterns, protein identification and characterization, and 2D protein databases.
