Accumulation of DNA damage in the first 1000 days may increase risk of accelerated ageing and degenerative diseases in adult life such as cancers. The extent of DNA damage in infants and the correlation of maternal factors during pregnancy with neonate birth outcomes and DNA damage is not known in infants born in Australia. Therefore, we performed a prospective cohort study to collect data on DNA damage in lymphocytes of Australian infants (aged 0, 3 and 6 months), using the cytokinesis block micronucleus cytome (CBMN-Cyt) assay...

Background.: Activation of the mitogen-activated protein kinase pathway is important for growth of pediatric low-grade gliomas (LGGs). The aim of this study was to determine the recommended phase II dose (RP2D) and the dose-limiting toxicities (DLTs) of the MEK inhibitor selumetinib in children with progressive LGG. Methods.: Selumetinib was administered orally starting at 33 mg/m2/dose b.i.d., using the modified continual reassessment method. Pharmacokinetic analysis was performed during the first course...

Background.: Diffuse intrinsic pontine glioma (DIPG) is a high-grade brainstem glioma of children with dismal prognosis. There is no single unifying model about the cell of origin of DIPGs. Proliferating cells in the developing human and mouse pons, the site of DIPGs, express neural stem/progenitor cell (NPC) markers, including Sox2, nestin, vimentin, Olig2, and glial fibrillary acidic protein, in an overlapping and non-overlapping manner, suggesting progenitor cell heterogeneity in the pons...

Experimental drug development is time-consuming, expensive and limited to a relatively small number of targets. However, recent studies show that repositioning of existing drugs can function more efficiently than de novo experimental drug development to minimize costs and risks. Previous studies have proven that network analysis is a versatile platform for this purpose, as the biological networks are used to model interactions between many different biological concepts. The present study is an attempt to review network-based methods in predicting drug targets for drug repositioning...

Recent genomic studies of sporadic clear cell renal cell carcinoma (ccRCC) have uncovered novel driver genes and pathways. Given the unequal incidence rates among men and women (male:female incidence ratio approaches 2:1), we compared the genome-wide distribution of the chromosomal abnormalities in both sexes. We observed a higher frequency for the somatic recurrent chromosomal copy number variations (CNVs) of autosomes in male subjects, whereas somatic loss of chromosome X was detected exclusively in female patients (17...

BACKGROUND: One of the most important environmental problems is the decontamination of petroleum hydrocarbons polluted soil, particularly in the oil-rich country. Bioremediation is the most effective way to remove these pollutants in the soil. Spent mushroom compost has great ability to decompose lignin-like pollution. The purpose of this study was the bioremediation of soil contaminated with crude oil by an Agaricomycetes. METHODS: Soil sample amended with spent mushroom compost into 3%, 5% and 10% (w/w) with or without fertilizer...

Lithophagia is a type of pica that might be resulted from Iron Deficiency Anemia (IDA) which is the frequent presenting signs of Celiac Disease (CD). A 5-year-old child with a two year history of the lithophagia with a, refractory IDA, abdominal distention and constipation. The child did not grow well and had failure to thrive. With suspicion to CD, TTg IgA level was measured and due to an incearse of TTg IgA level the patients were undergone esophagogastrodeudonoscpy and jejunal biopsy. The biopsy showed severe villous atrophy and an increase in limphoplasma cells...

Microsatellite markers containing simple sequence repeats (SSRs) are a valuable tool for genetic analysis. Date palm is a dioecious and slow flowering and is very difficult to identify the gender of the trees until it reaches the reproductive age (5-10 years). A total of 12 microsatellite primers were used with 30 date palm samples, 14 parents (8 male + 6 females) and 16 progeny (developed from parents breeding) which showed that microsatellites were highly polymorphic, having a great number of alleles. A total of 124 alleles were characterized in 12 SSR loci...

PURPOSE: Alumina air abrasion is an alternative for acid-etch technique for tooth preparation before placement of a fissure sealant. The aim of this study was to compare the retention of sealants placed subsequent to air abrasion with alumina and bioactive glass (BAG) particles. METHODS: Sixty-two 6-12 year old children were included in this study. Using a halfmouth design, the fissures were prepared using air abrasion with alumina particles on randomly assigned permanent mandibular or/and maxillary first molars on one side of the mouth (Group 1) and air abrasion with BAG on the contralateral side of the mouth (Group 2)...

K289M is a variant of DNA polymerase β (pol β) that was previously identified in colorectal cancer. The expression of this variant leads to a 16-fold increase in mutation frequency at a specific site <i>in vivo</i> and a reduction in fidelity <i>in vitro</i> in a sequence context-specific manner. Previous work shows that this reduction in fidelity results from decreased discrimination against incorrect nucleotide incorporation at the level of polymerization. To probe the transition state of the K289M mutator variant of pol β, single turnover kinetics experiments were performed using β,γ-CXY dGTP analogues with a wide range of leaving group monoacid dissociation constants (p<i>K</i><sub>a4</sub>), including a corresponding set of novel β,γ-CXY dCTP analogues...

DNAzyme and aptamer conjugations have already been used for sensitive and accurate detection of several molecules. In this study, we tested the relationship between conjugation orientation of DNAzyme and Aflatoxin B1 aptamer and their subsequent peroxidase activity. Circular dichroism (CD) spectroscopy and biochemical analysis were used here to difference between these two conjugation patterns. Results showed that DNAzyme-aptamer has more catalytic activity and efficiency than aptamer-DNAzyme. Thereby, DNAzyme-aptamer with its superior efficiency can be used for design and development of more sensitive Aflatoxin B1 DNA based biosensors...
