Abstract
Β-arrestins are intracellular scaffolding proteins that have multifaceted roles in different types of disorders. In this review article, we gave a summary about the discovery, characterization and classification of these proteins and their intracellular functions. Moreover, this review article focused on the hepatic expression of β-arrestins and their hepatocellular distribution and function in each liver cell type. Also, we showed that β-arrestins are key regulators of distinct types of hepatic disorders. On the other hand, we addressed some important points that have never been studied before regarding the role of β-arrestins in certain types of hepatic disorders which needs more research efforts to cover.

Abstract
Haematopoiesis, the process of blood production, occurs from a tiny contingent of haematopoietic stem cells (HSC) in highly specialised three-dimensional niches located within the bone marrow. When haematopoiesis is replicated using in vitro two-dimensional culture, HSCs rapidly differentiate, limiting self-renewal. Emulsion-templated highly porous polyHIPE foam scaffolds were chosen to mimic the honeycomb architecture of human bone. The unmodified polyHIPE material supports haematopoietic stem and progenitor cell (HSPC) culture, with successful culture of erythroid progenitors and neutrophils within the scaffolds. Using erythroid culture methodology, the CD34+ population was maintained for 28 days with continual release of erythroid progenitors. These cells are shown to spontaneously repopulate the scaffolds, and the accumulated egress can be expanded and grown at large scale to reticulocytes. We next show that the polyHIPE scaffolds can be successfully functionalised using activated BM(PEG)2 (1,8-bismaleimido-diethyleneglycol) and then a Jagged-1 peptide attached in an attempt to facilitate notch signalling. Although Jagged-1 peptide had no detectable effect, the BM(PEG)2 alone significantly increased cell egress when compared to controls, without depleting the scaffold population. This work highlights polyHIPE as a novel functionalisable material for mimicking the bone marrow, and also that PEG can influence HSPC behaviour within scaffolds.

Abstract
Summary Background. Attention deficit hyperactivity disorder (ADHD) is commonly present worldwide, causing serious problems to those affected. ADHD was suggested to be secondary to allergic disorder or its medication. Both ADHD and allergy depend on complex environmental and genetic interaction, and they meet the hypersensitivity criteria. Objective. Detect the percentage of allergy in ADHD children, the common allergic disorders and allergens, and the effect of allergy on symptom and severity of ADHD. Material and methods. 100 children with ADHD were subjected to psychiatric assessment for ADHD type and severity, history of allergy, skin prick test to common environmental allergens, serum total IgE levels and open food challenge. Co-morbid neuropsychiatric disorders, below average intelligence quotient (IQ), and chronic illnesses were excluded. A control of 60 healthy children was chosen to compare the results of skin prick test and serum total IgE levels. Results. 35 ADHD children (35%) were allergic. Most cases had combined allergic rhinitis and bronchial asthma (25%). Common allergens were hay dust (43%) followed by different pollens (37.5%). There were statistical significant differences between coexistence of allergy, type of ADHD, early onset and severity of symptoms. Conclusion. Children with ADHD had an increased prevalence of allergic diseases. Evaluation of allergy in ADHD is mandatory, to decrease the burden of the condition.

Abstract
This study was conducted to determine the prevalence of rheumatic heart disease (RHD) and congenital heart disease (CHD) in primary schoolchildren of Menoufia, Egypt and to study the relationship between these two problems and socioeconomic conditions. A total of 8000 children were screened for cardiac disease in their schools. Children with confirmed RHD and CHD in addition to 200 healthy children (controls) were visited at their homes to assess their social environment and other factors according to a designed questionnaire. We found prevalence rates of 3.4/1000 and 2.6/1000 for the RHD and CHD respectively. The most common cardiac defects were double mitral and pulmonary stenosis in the RHD and CHD groups respectively. Nineteen (39.6%) of the patients were diagnosed for the first time during the study. Penicillin prophylaxis was received by only four (14.8%) of the RHD children and none of the CHD children. The number of other affected siblings, increased multiparity, repeated abortion, and intake of contraceptives by mothers were significantly higher in families of the children with CHD. The proportion of illiterate, unskilled, and heavy smoking fathers was higher in the two patient groups. Family income was lowest in the RHD group, while increased crowding index and low whole social environment were significantly related to both RHD and CHD. Effective programs at the community and health service levels are needed in Menoufia to solve the problem of heart disease in schoolchildren in the immediate future.

Abstract
The study of Histocompatibility Locus Antigen (HLA) frequencies in 48 cases with congenital heart disease (CHD) in children in Cairo showed high incidence of A10. Cases with atrial septal defect have shown a significant association with A3 besides A10. There is also a significant association between B12-45 and right loop anomalies (Fallot's and pulmonary stenosis) together with A10. On the other hand, children with rheumatic heart disease have shown strong positive association with HLA group B8 and negative association with A28.
