Association of the DYX1C1 Gene with Chinese Literacy in a Healthy Chinese Population

DYX1C1, the first dyslexia candidate gene, has been associated with developmental dyslexia in different populations, but its influence on reading abilities in the general population is less well known. Copy number variants (CNVs) have been implicated in neurodevelopmental and childhood-onset disorders involving cognitive development in previous studies. In this report, we investigated the extent to which genomic CNVs for the SNP previously linked to dyslexia, -3G/A (rs3743205) in the gene DYX1C1, contribute to Chinese and English literacy in the general population in a Chinese cohort, and whether these processes, in turn, are influenced by environmental factors, such as family income, parents’ education, and IQ. Our findings suggest that the logR ratio (which is a way to detect CNVs) of a previously reported dyslexia-related SNP, -3G/A (rs3743205) is significantly associated with Chinese literacy in a cohort of Chinese children with normal reading abilities

Expression and functional characterization of the putative protein 8b of the severe acute respiratory syndrome-associated coronavirus

AbstractSARS 8b is one of the putative accessory proteins of the severe acute respiratory syndrome-associated coronavirus (SARS-CoV) with unknown functions. In this study, the cellular localization and activity of this estimated 9.6kDa protein were examined. Confocal microscopy results indicated that SARS 8b is localized in both nucleus and cytoplasm of mammalian cells. Functional study revealed that overexpression of SARS 8b induced DNA synthesis. Coexpression of SARS 8b and SARS 6, a previously characterized SARS-CoV accessory protein, did not elicit synergistic effects on DNA synthesis

Isolation and characterization of a human heart cDNA encoding a new member of the small heat shock protein family — HSPL27

AbstractA novel cDNA clone was isolated from a human adult heart cDNA library. This cDNA clone is similar to the small heat shock protein (smhsp) in both DNA and amino acid sequences, especially in the conserved region. Sequence analysis has shown that the putative novel smhsp, named 27 kDa heat-shock-protein-like protein (HSPL27) is a protein of 241 amino acids with a deduced molecular mass of 26.7 kDa and a deduced pI of 8.0. We have expressed the HSPL27 in E. coli and the expressed protein was found to be present in the soluble fraction of the bacterial cell lysate. Chromosomal mapping data shows that the HSPL27 gene is located at human chromosome 5q11.2

Anti-Viral Drugs for Human Adenoviruses

There are many stages in the development of a new drug for viral infection and such processes are even further complicated for adenovirus by the fact that there are at least 51 serotypes, forming six distinct groups (A–F), with different degree of infectivity. This review attempts to address the importance of developing pharmaceuticals for adenovirus and also review recent development in drug discovery for adenovirus, including newer strategies such as microRNA approaches. Different drug screening strategies will also be discussed

Nursing students' perceived anxiety and heart rate variability in mock skill competency assessment.

BackgroundSkill competency assessments induce stress and anxiety and may affect nursing student performance. Little is known about stress and perceived anxiety levels and their relationship in the mock skill competency assessment.MethodsA cross-sectional study was conducted to examine the stress levels (as assessed by heart rate variability, HRV) and perceived anxiety before, during and after the mock skill competency assessment, and to explore their relationships to performance in a total of ninety first-year undergraduate nursing students.ResultsThe HRV decreased significantly during the assessment and increased significantly 10 min after the assessment (p ConclusionsConsidering assessment-related stress and anxiety through a mock assessment prior to the actual skill assessment provides implications for future nursing education

Intervention Efficacy of Slightly Processed Allergen/Meat in Oral Immunotherapy for Seafood Allergy: A Systematic Review, Meta-Analysis, and Meta-Regression Analysis in Mouse Models and Clinical Patients

Background: Seafood allergy is a significant global health concern that greatly impacts a patient’s quality of life. The intervention efficacy of oral immunotherapy (OIT), an emerging intervention strategy, for seafood allergy remains controversial. This study aimed to perform a systematic review and meta-analysis to evaluate the efficacy of slightly processed allergen/meat from fish and crustacea in OIT, both in mouse models and clinical patients. Methods: A comprehensive literature search was performed in four mainstream databases and the EBSCOhost database to identify all relevant case–control and cohort studies. The aim was to elucidate the intervention efficacy, encompassing various processing methods and assessing the efficacy of multiple major allergens in OIT. Results: The meta-analysis included five case–control studies on crustacean allergens in mouse models and 11 cohort studies on meat from fish and crustacea in clinical patients for final quantitative assessments. In mouse models, crustacean allergen substantially decreased the anaphylactic score after OIT treatment (mean difference (MD) = −1.30, p p 2 = 0), arginine kinase allergen (MD = −0.83, p 2 = 0), and Maillard reaction processing method (MD = −0.65, p 2 = 29%), respectively. In clinical patients, the main meta-analysis showed that the slightly processed meat significantly increased the incidence rate of oral tolerance (OT, incidence rate ratio (IRR) = 2.90, p p p = 0.01) also demonstrated a substantial increase in the incidence rate of OT. Sensitivity and meta-regression analyses successfully identified specific studies contributing to heterogeneity in mouse models and clinical patients, although these studies did not impact the overall significant pooled effects. Conclusions: This meta-analysis provides preliminary evidence for the high intervention efficacy of slightly processed allergen/meat from fish and crustacea in OIT, both in mouse models and clinical patients. The Maillard reaction and cooking processing methods may emerge as potentially effective approaches to treating allergen/meat in OIT for clinical patients, offering a promising and specific treatment strategy for seafood allergy. However, these findings should be interpreted cautiously, and further supporting evidence is necessary
