The aristaless (Arx) gene: one gene for many "interneuronopathies".
2009
The ARX (Aristaless-related (X-linked) homeobox) gene is not only present in arthropods and their ancestors, but also in vertebrates including humans (ARX orthologs). The gene is composed of 5 coding exons and it is expressed predominantly in foetal and adult brain and skeletal muscle. In this review we report on our experience and review the existing literature on the genotype and phenotype heterogeneity associated with ARX abnormalities in humans ranging from severe neuronal migration defects (e.g., lissencephaly), to mild forms of X-linked mental retardation without apparent brain abnormalities. The ARX-related disorders are reviewed focusing on their clinical features and on the role of…
Lip and oral lesions in children with Down syndrome. A controlled study
2015
Background: Down syndrome (DS) is the most common chromosomal abnormality affecting numerous organs, including the orofacial region. The objective of the present study was to assess the prevalence of lip and oral soft tissue lesions, with particular emphasize on the incidence of fissured tongue, lip fissures and angular cheilitis, among individuals with DS in Yemen. Material and Methods: This controlled cross-sectional study included 50 children with DS (6-18 years), and 50 age- and gender-matched healthy controls. The prevalence of orofacial soft tissue lesions was evaluated in both groups. Data were analyzed by Chi-square and Fisher tests, and p <0.05 was considered to be statistically si…
SWALLOWING, SPEECH AND OROFACIAL DISORDERS IN CHILDREN WITH ADENOTONSILLAR HYPERTROPHY
2022
A prospective observational study was conducted to evaluate the presence of swallowing, speech and orofacial muscle imbalance (OMI) disorders in patients with adenotonsillar hypertrophy and their regression after surgery. ENT, speech therapist and dentistry examination were conducted before and 12 months after surgery in 78 children between the ages of 2 and 12 with dysphagia, speech disorders and OMI adenotonsillar hypertrophy related with sleep-disordered breathing. Of the 78 patients enrolled, 62 underwent adenotonsillectomy, 9 adenoidectomy and 7 volume reduction of the palatine tonsils with a 12-month post-operative increase in SWAL-QOL score, weight gain, correction of ogival palate, …
The distribution of stock returns: international evidence
1994
Although financial theory rests heavily on the normality assumption, daily stock returns display significant departures from normality. Different researchers have proposed alternative distributions. In this paper, the distribution of stock returns is examined in six stock markets. The empirical distributions present common features and are best represented by Student's t-distribution, while several alternative distributions are rejected.
Rheological blood behaviour is not related to gender in morbidly obese subjects.
2012
To the Editor. We have read with interest the recently published article by Wiewiora et al. [7] regarding hemorheological differences related to gender in morbidly obese subjects. In this study authors found several hemorheological differences between male and female. In this sense, males showed higher blood viscosity and higher erythrocyte deformability than females and native blood viscosity correlated with several erythrocyte aggregation parameters evaluated with the Laser-Assisted Optical Rotational Cell Analyser (LORCA) [3]. In studies with small sample sizes (18 men and 20 women) there is always the risk that differences in certain variables may appear by chance or by imbalances in th…
Application of transvaginal and abdominal three-dimensional ultrasound for the detection or exclusion of malformations of the fetal face
1997
In a total of 618 pregnant women between 9 and 37 weeks' gestation, the fetal face was evaluated by two-dimensional and three-dimensional ultrasound imaging as part of a level III screening evaluation for fetal anomalies. A three-dimensional endovaginal probe (5 MHz) was used for examinations at between 9 and 15 weeks, and an abdominal three-dimensional probe (3.5 MHz) was used after 15 weeks. Three different three-dimensional image display modes were employed: (1) the orthogonal display; (2) the surface display; and (3) the transparent display. When we studied the three-dimensional orthogonal displays in 125 cases evaluated by abdominal ultrasound, we found that the facial profile shown in…
On finite soluble groups in which Sylow permutability is a transitive relation
2003
A characterisation of finite soluble groups in which Sylow permutability is a transitive relation by means of subgroup embedding properties enjoyed by all the subgroups is proved in the paper. The key point is an extension of a subnormality criterion due to Wielandt.
On generalised FC-groups in which normality is a transitive relation
2016
We extend to soluble FC∗ -groups, the class of generalised FC-groups introduced in [F. de Giovanni, A. Russo, G. Vincenzi, Groups with restricted conjugacy classes , Serdica Math. J. 28(3) (2002), 241 254], the characterisation of finite soluble T-groups obtained recently in [G. Kaplan, On T-groups, supersolvable groups and maximal subgroups , Arch. Math. 96 (2011), 19 25].
Kraniometrische Merkmale bei unterschiedlichen Anomalien
1972
Die vorangegangenen Ausfuhrungen verfolgten das Ziel, die Frage aufzuhellen, ob fur Anomalien des Kieferbereiches eine weitgehende Unabhangigkeit vom Aufbau des Gesichtsschadels besteht. Zu diesem Zweck wurden je 10 Fernrontgen-Profilaufnahmen von 5 typischen Anomaliegruppen ausgewahlt und im Hinblick auf die Fragestellung ausgewertet. Das mit Hilfe biostatistischer Verfahren gewonnene Ergebnis gibt zu erkennen, das keine der gewahlten Variablen des Gesichtsschadels eine spezifische Zuordnung zu einer bestimmten Anomaliegruppe ermoglichte. Zwischen kraniometrischen Merkmalen und Gebisanomalien bestehen demnach keine engeren Beziehungen.
Dictating the boundaries of ab/normality: a critical discourse analysis of the diagnostic criteria for attention deficit hyperactivity disorder and h…
2017
In this article we report the findings of a critical discourse analysis of the diagnostic criteria for attention deficit hyperactivity disorder (ADHD) and hyperkinetic disorder (HD) in two clinical manuals – Diagnostic and Statistical Manual of Mental Disorders, 5th edition and International Classification of Diseases, 10th edition. We examine the actions (behaviors) that are said to indicate the presence of ADHD/HD and analyze what the inclusion of these actions reveals about the relationship between ADHD/HD, cultural knowledge, and values. Our analysis reveals that both manuals use subjective, value-laden language to construct a mentally ill individual in opposition to an unseen, supposed…
