Segmental Duplications: a Possible Mechanism of Hominid Uplift Through MicroRNA Diversification

MicroRNAs (miRNA) are ~21 nucleotide-long gene silencers. Segmental duplications (SD) are among the driving forces in acquiring new genes. Both miRNA and SD are believed to have played a significant role in evolution, particularly in the divergence of humans (Homo sapiens) from the chimpanzee (Pan troglodytes). This study determines the distribution of miRNAs in humans and in chimpanzees, and presents a hypothesis on its significance in the occurrence of segmental duplications. MiRNA sequences from miRBASE were subjected to BLAT and BLAST to determine if miRNAs are located in SD regions or not. Homology between miRNAs was determined with ClustalW. BLAST was then used to determine whether the non-homologous human miRNA are homologous to any other part of the chimpanzee genome. We found that all 695 human miRNAs are found exclusively in SD regions, and that 67 are de novo miRNAs. Thirteen are homologues of chimpanzee miRNA, and 11 were possibly derived from non-miRNA regions in chimp. Of these, 6 were located in SD regions of the chimpanzee genome. Results indicate that miRNA evolution occurs within regions of segmental duplication and suggest that the presence of miRNA duplicates allows more exposure to mutations that could necessitate diversification, and possibly evolution, through sub- and neofunctionalization

HOX Gene Promoter Prediction and Inter-genomic Comparison: an Evo-Devo Study

Homeobox genes direct the anterior-posterior axis of the body plan in eukaryotic organisms. Promoter regions upstream of the Hox genes jumpstart the transcription process. CpG islands found within the promoter regions can cause silencing of these promoters. The locations of the promoter regions and the CpG islands of Homeo sapiens sapiens (human), Pan troglodytes (chimpanzee), Mus musculus (mouse), and Rattus norvegicus (brown rat) are compared and related to the possible influence on the specification of the mammalian body plan. The sequence of each gene in Hox clusters A-D of the mammals considered were retrieved from Ensembl and locations of promoter regions and CpG islands predicted using Exon Finder. The predicted promoter sequences were confirmed via BLAST and verified against the Eukaryotic Promoter Database. The significance of the locations was determined using the Kruskal-Wallis test. Among the four clusters, only promoter locations in cluster B showed significant difference. HOX B genes have been linked with the control of genes that direct the development of axial morphology, particularly of the vertebral column bones. The magnitude of variation among the body plans of closely-related species can thus be partially attributed to the promoter kind, location and number, and gene inactivation via CpG methylation

Appearance concerns in ophthalmic patients

Aims: This study aimed to determine the psychosocial and appearance-related concerns of a sample of ophthalmic patients by measuring a range of psychological, social, and demographic factors. Methods: Standardized psychological measures including anxiety, depression, appearance-related distress, self-discrepancy, appearance salience and valence were administered to 98 participants attending ophthalmic outpatient clinics in either London, Bristol, Sheffield or Bradford. Differences between groups were explored using t-tests and ANOVA, relationships between all variables were investigated using Pearson's correlation coefficient. Results: Although mean scores for psychological adjustment were within the normal range, some participants were experiencing considerable levels of generalized anxiety. Being older, male, and married or living with a partner was related to significantly better adjustment. Better adjustment was also related to a less visible area of concern, greater disguisability of the affected area, a more positive evaluation of their own appearance, less engagement in comparing themselves with others, greater feelings of being accepted by others, appearance being less important to their self-concept, and a smaller discrepancy between the persons ideal and actual appearance. Conclusions: A majority of ophthalmic patients adjust positively to the demands placed on them. By identifying the variables that are associated with successful adaptation, the specific psychological interventions and appropriate systems of support can be put in place to help those who are adversely affected

Hyperactivity, impulsivity, and inattention in boys with cleft lip and palate: relationship to ventromedial prefrontal cortex morphology

The purpose of this study is to evaluate quantitative structural measures of the ventromedial prefrontal cortex (vmPFC) in boys with isolated clefts of the lip and/or palate (ICLP) relative to a comparison group and to associate measures of brain structure with quantitative measures of hyperactivity, impulsivity, and inattentiveness. A total of 50 boys with ICLP were compared to 60 healthy boys without clefts. Magnetic resonance imaging brain scans were used to evaluate vmPFC structure. Parents and teachers provided quantitative measures of hyperactivity, impulsivity, and inattentiveness using the Pediatric Behavior Scale. Boys with ICLP had significantly higher ratings of hyperactivity/impulsivity/inattention (HII) and significantly increased volume of the right vmPFC relative to the comparison group. There was a direct relationship between HII score and vmPFC volume in both the ICLP group and control group, but the relationship was in the opposite direction: in ICLP, the higher the vmPFC volume, the higher the HII score; for the comparison group, the lower the vmPFC volume, the greater the HII score. The vmPFC is a region of the brain that governs behaviors of hyperactivity, impulsivity and inattention (HII). In boys with ICLP, there are higher levels of HII compared to the controls and this is directly related to a significantly enlarged volume of the right vmPFC. Enlargement of this region of the brain is therefore considered to be pathological in the ICLP group and supports the notion that abnormal brain structure (from abnormal brain development) is the underlying etiology for the abnormal behaviors seen in this population

Psychological impact of visible differences in patients with congenital craniofacial anomalies

© 2015, Singh and Moss; licensee Springer. Background: Patients with craniofacial anomalies often have appearance concerns and related social anxiety which can affect their quality of life. This study assessed the psychological impact of facial and dental appearance in patients with craniofacial anomalies in comparison to a general population control group. Methods: The study involved 102 adult patients (51% male) with congenital craniofacial anomalies and 102 controls (49% male). Both groups completed the Nepali version of Derriford Appearance Scale (DAS) and the Psychological Impact of Dental Aesthetic Questionnaire (PIDAQ) in a clinical setting to assess appearance-related distress, avoidance, and anxiety. Results: There was a significant difference between patients and controls on both PIDAQ (mean score for patients 33.25 ± 9.45 while for controls 27.52 ± 5.67, p < 0.001) and DAS59 scores (mean score for patients 159.16 ± 31.54 while for controls 77.64 ± 6.57, p < 0.001), indicating that patients experienced greater negative psychological impact of living with their appearance (PIDAQ) and more appearance-related distress (DAS) than controls. DAS scores were not associated with gender. There was no association of the place of residence (rural vs. urban) with PIDAQ or DAS59 scores. Conclusions: There is a significant psychological impact of altered facial and dental appearance in patients with craniofacial anomalies compared to controls. There was no effect of locality (rural/urban) on the psychological impact of facial and dental appearance in patients

Executive control of bureaucracy and presidential cabinet appointments in East Asian democracies

This article examines the role of cabinet appointments in controlling the bureaucracy in presidential democracies. I demonstrate how administrative challenges stemming from the structure of the bureaucracy shape presidential choice of ministers. Analyzing a sample of four East Asian cases from 1986 through 2013, I find that presidents are more likely to select ministers from the civil service as bureaucracies are more professionalized, controlling for several political factors. Further evidence from qualitative interviews and case studies suggests that, in professionalized systems equipped with a sizable pool of talent but lacking responsiveness, presidents tend to promote ideologically aligned senior civil servants. However, in politicized systems, where presidents easily obtain responsiveness but face a low level of competence, policy experts tend to be selected from outside the bureaucracy. My findings have important implications for the regulatory governance and state capacity of East Asia, demonstrating the value of balancing between responsiveness and competence
