BACKGROUND: Neonatal adiposity has many determinants and may be a risk factor for future obesity. Epigenetic regulation of metabolically important genes is a potential contributor. OBJECTIVES: The objective of the study is to determine whether methylation changes in the LEP gene in cord blood DNA are impacted by the maternal environment or affect neonatal adiposity measures. METHODS: A cross-sectional study of 114 full-term neonates born to healthy mothers with normal glucose tolerance was performed...

We have established a coupled assay system targeting protein l-isoaspartyl methyltransferase (PIMT), a key enzyme in the metabolism of isoaspartyl peptides and proteins. The system utilizes a fluorogenic peptide probe containing an isoaspartyl residue at the P1' position of the caspase-3 recognition sequence. Following PIMT-catalyzed methyl transfer reaction, the methylated probe is specifically cleaved by caspase-3 to give fluorescence activation. High-throughput screening of our chemical library with this assay system identified PIMT inhibitors that may be useful as leads in the design of chemical probes for controlling PIMT activity...

Aptamers are a promising class of affinity reagents because they are chemically synthesized, thus making them highly reproducible and distributable as sequence information rather than a physical entity. Although many high-quality aptamers have been previously reported, it is difficult to routinely generate aptamers that possess both high affinity and specificity. One of the reasons is that conventional aptamer selection can only be performed either for affinity (positive selection) or for specificity (negative selection), but not both simultaneously...

BACKGROUND: Suboptimal nutrition accompanied by chronic low-grade increases in circulating cytokine levels is more common in elderly people. We explored the improvement in nutritional status, especially in the level of insulin-like growth factor-1 (IGF-1) and its relationship with changes in circulating cytokine levels, after providing extra protein and energy content to community-dwelling older adults at risk of undernutrition. METHODS: Sixty nondiabetic subjects, aged ≥65 years and living independently in a community for elderly people, with a serum pre-albumin level ≤30 mg dL(-1) and a body mass index <25 kg m(-2) , were recruited...

SleepMapper is a mobile, web-based system that allows patients to self-monitor their positive airway pressure therapy, and provides feedback and education in real time. In addition to the usual, comprehensive support provided at our clinic, we gave the SleepMapper to 30 patients initiating positive airway pressure. They were compared with patients initiating positive airway pressure at our clinic without SleepMapper (controls) to determine whether SleepMapper affected adherence. A total of 61 patients had polysomnographic and adherence data analysed, 30 were given SleepMapper and 31 received our standard of care...

BACKGROUND AND AIMS: There is a paucity of data on left ventricle (LV) rotational physiology in neonates. We aimed to assess rotational mechanics in infants with hypoxic ischemic encephalopathy (HIE) and premature infants (<32 weeks) at 36 weeks postmenstrual age (PMA) (preterm group) and compare them with healthy term controls (term controls). We also compared the parameters in preterm infants with and without chronic lung disease (CLD). METHODS: Echocardiography was performed within 48 hours of birth or at 36 weeks PMA...

Antisperm antibodies have been found in repeat-breeding(RB) cows, and those causing agglutination and/or immobilization of sperm are considered to be closely related to unexplained infertility. However, a standard protocol for identifying antisperm antibodies (ASA) in cattle is not validated. Therefore, an investigation was undertaken to evaluate sperm immobilization (SIT), sperm agglutination (SAT) and immunoperoxidase (IPT)assays for detection of ASA in serum and their respective threshold levels for confirmation...

BACKGROUND: Mental pressure and stress represent an ever-increasing socio-political challenge. The heart rate variability (HRV) measurement, which has its origin in the cardiac function diagnosis, gives information on the neurovegetative activity. A low HRV shows an imbalance of the sympathetic and parasympathetic efferents and thus is an indicator of stress. METHOD: A randomized, controlled, two-armed parallel study with 100 participants and a period of 90 days was performed...

We report the results from two experiments examining native and non-native German speakers' sensitivity to crossover constraints on pronoun resolution. Our critical stimuli sentences contained personal pronouns in either strong (SCO) or weak crossover (WCO) configurations. Using eye-movement monitoring during reading and a gender-mismatch paradigm, Experiment 1 investigated whether a fronted wh-phrase would be considered as a potential antecedent for a pronoun intervening between the wh-phrase and its canonical position...

The nested PCR was used to estimate its inputs in malaria diagnosis and in the performance of the microscope operators involved in the surveillance of malaria in remote areas of South Algeria. For the period 2010 to 2015, 112 patients (93 febrile and 19 asymptomatic) coming from sub-Saharan Africa were tested for malaria in the hospital of Tamanrasset. One part of the blood taken from fingertip was used for blood smears and the second part was absorbed in filter paper for molecular diagnosis. Overall, the infection was detected by nested PCR in 63 samples versus 53 by direct examination...

The genotoxicity of river water dissolved contaminants is usually estimated after grab sampling of river water. Water contamination can now be obtained with passive samplers that allow a time-integrated sampling of contaminants. Since it was verified that low density polyethylene membranes (LDPE) accumulate labile hydrophobic compounds, their use was proposed as a passive sampler. This study was designed to test the applicability of passive sampling for combined chemical and genotoxicity measurements. The LDPE extracts were tested with the umu test (TA1535/pSK1002 ± S9) and the Ames assay (TA98, TA100 and YG1041 ± S9)...

This chapter describes methods currently available for visualizing results from systems genetics experiments. Here, we abstract from the statistical methods used for genetic mapping, which are dependent on the specific resource being used, i.e. F2, RILs, or outbred populations among others. We use a public dataset with results from a mouse eQTL experiment for three examples of visualization: genome-wide dot plots of marker-by-gene association, karyotype-like plots, and circos plots. Dot plots give a first overview of the results from eQTL mapping, allowing detecting genome-wide patterns of cis- and trans-genetic association to transcription level...

The aim of expression Quantitative Trait Locus (eQTL) mapping is the identification of DNA sequence variants that explain variation in gene expression. Given the recent yield of trait-associated genetic variants identified by large-scale genome-wide association analyses (GWAS), eQTL mapping has become a useful tool to understand the functional context where these variants operate and eventually narrow down functional gene targets for disease. Despite its extensive application to complex (polygenic) traits and disease, the majority of eQTL studies still rely on univariate data modeling strategies, i...

The abundance of existing functional genomics studies permits an integrative approach to interpreting and resolving the results of diverse systems genetics studies. However, a major challenge lies in assembling and harmonizing heterogeneous data sets across species for facile comparison to the positional candidate genes and coexpression networks that come from systems genetic studies.

Imidazole ring is a known structure in many natural or synthetic drug molecules and its metal complexes can interact with DNA and do the cleavage. Hence, to study the influence of the structure and size of the ligand on biological behavior of metal complexes, two water-soluble Pd(II) complexes of phen and FIP ligands (where phen is 1,10-phenanthroline and FIP is 2-(Furan-2-yl)-1H-Imidazo[4,5-f][1, 10]phenanthroline) with the formula of [Pd(phen)(FIP)](NO3)2 and [Pd(FIP)2]Cl2, that were activated against chronic myelogenous leukemia cell line, K562, were selected...
