REVIEW
Ozren Bogdanović, Ryan Lister
DNA methylation is a major epigenetic modification of vertebrate genomes that is mostly associated with transcriptional repression. During embryogenesis, DNA methylation together with other epigenetic factors plays an essential role in selecting and maintaining cell identity. Recent technological advances are now allowing for the exploration of this mark at unprecedented resolution. This has resulted in a wealth of studies describing the developmental roles of DNA methylation in various vertebrate model systems...

Monte Carlo track structure codes provide valuable information for understanding radiation effects down to the DNA level, where experimental measurements are most difficult or unavailable. It is well recognized that the performance of such codes, especially at low energies and/or subcellular level, critically depends on the reliability of the interaction cross sections that are used as input in the simulation. For biological media such as liquid water, one of the most challenging issues is the role of condensed-phase effects...

In the search for Mn(II) MR and PET/MR imaging agents with optimal balance between thermodynamic stability, kinetic inertness, and relaxivity, two novel bifunctional Mn(II) chelators (BFMnCs) based on CDTA (trans-1,2-diaminocyclohexane-N,N,N',N'-tetraacetic acid) were synthesized. A six-step synthesis, involving the buildup of a functionalized trans-1,2-diaminocyclohexane core, provided CuAAC-reactive 6a and 6b bearing an alkyne or azide substituent on the cyclohexane ring, respectively (CuAAC = Cu(I)-catalyzed azide-alkyne 1,3-dipolar cycloaddition)...

Neuroblastoma and other pediatric tumors show a paucity of gene mutations, which has sparked an interest in their epigenetic regulation. Several tumor types include phenotypically divergent cells, resembling cells from different lineage development stages. It has been proposed that super-enhancer-associated transcription factor (TF) networks underlie lineage identity, but the role of these enhancers in intratumoral heterogeneity is unknown. Here we show that most neuroblastomas include two types of tumor cells with divergent gene expression profiles...

In plants, cell-cell recognition is a crucial step in the selection of optimal pairs of gametes to achieve successful propagation of progeny. Flowering plants have evolved various genetic mechanisms, mediated by cell-cell recognition, to enable their pistils to reject self-pollen, thus preventing inbreeding and the consequent reduced fitness of progeny (self-incompatibility, SI), and to reject foreign pollen from other species, thus maintaining species identity (interspecific incompatibility)(1). In the genus Brassica, the SI system is regulated by an S-haplotype-specific interaction between a stigma-expressed female receptor (S receptor kinase, SRK) and a tapetum cell-expressed male ligand (S locus protein 11, SP11), encoded by their respective polymorphic genes at the S locus(2-6)...

Unrelated cord blood transplantation (UCBT) after a reduced intensity conditioning regimen (RIC) has extended the use of UCB in elderly patients and those with co-morbidities without an HLA-identical donor, although post-transplant relapse remains a concern in high-risk acute myeloid leukemia (AML) patients. HLA incompatibilities between donor and recipient might enhance the alloreactivity of natural killer (NK) cells after allogeneic hematopoietic stem-cell transplantation (HSCT). We studied the reconstitution of NK cells and KIR-L mismatch in 54 patients who underwent a RIC-UCBT for AML in CR in a prospective phase II clinical trial...

BACKGROUND AND PURPOSE: Motor rehabilitation following stroke is a demanding challenge in search for new strategies to improve outcome. Rehabilitation through action observation has been reported beneficial for older adults recovering from stroke. Early sleep session following motor learning enhanced the performance of the acquired motor skills. The purpose of this study was to examine whether an early sleep session following action observation has benefit over action observation alone in the rehabilitation of older adults after stroke...

OBJECTIVES: It is well known from previous research that when listeners are told what they are about to hear before a degraded or partially masked auditory signal is presented, the speech signal "pops out" of the background and becomes considerably more intelligible. The goal of this research was to explore whether this priming effect is as strong in older adults as in younger adults. DESIGN: Fifty-six adults-28 older and 28 younger-listened to "nonsense" sentences spoken by a female talker in the presence of a 2-talker speech masker (also female) or a fluctuating speech-like noise masker at 5 signal-to-noise ratios...

An extremely halophilic archaeon, designated strain 5-3T, was isolated from a soil sample of Meighan wetland in Iran. Strain 5-3T was strictly aerobic, catalase-positive and oxidase-negative. Cells were Gram-stain-negative, non-motile and ovoid. Colonies of strain 5-3T were cream-coloured. The isolate showed optimum growth at 4.0 M NaCl, 40 °C and pH 7.0. The major polar lipids of the strain were phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester, two unknown phospholipids and three glycolipids (including one that was chromatographically identical to S2-DGD)...

Despite the disproportionate burden of HIV facing transgender youth, they continue to be under-represented in studies to provide an empirical basis for pre-exposure prophylaxis (PrEP) programs that can meet the unique needs of this population. This study examined facilitators and barriers to participation in a PrEP adherence study, determined through an online survey administered to 90 transgender male and 60 transgender female 14-21-year-olds attracted to cisgender male sexual partners. Approximately 50% reported likely to participate in the PrEP study...

This study explicates nomophobia by developing a research model that identifies several determinants of smartphone separation anxiety and by conducting semantic network analyses on smartphone users' verbal descriptions of the meaning of their smartphones. Structural equation modeling of the proposed model indicates that personal memories evoked by smartphones encourage users to extend their identity onto their devices. When users perceive smartphones as their extended selves, they are more likely to get attached to the devices, which, in turn, leads to nomophobia by heightening the phone proximity-seeking tendency...

OBJECTIVES: Family relationships, widely recognized as core to Latino cultures, are known to vary for Latina/o immigrants based on time in the United States. Less is known about (a) how acculturation explains differences in family relationships by time in the US, and (b) whether acculturative stressors influence different aspects of immigrants' family relationships. Drawing on an expanded acculturation framework, we explore whether and how attitudinal familism, family contact, and family conflict among immigrant Latina/os vary based on acculturation and acculturative stressors...

The vista paradox is the illusion in which an object seen through an aperture appears to shrink in apparent size as the observer approaches the aperture. In four studies, we tested the effect of framing and fixating on the target object. The first two studies assessed the vista paradox in a large scale naturalistic setting in which a 162.26 -m long corridor was aligned to a 97.2 -m high tower (1,407 m away). In the first study, the results showed, for each 16 m section, a mean 9.95% tower enlargement in the moving backward condition, and a mean 11...

The catalytic polymerization of ethylene is performed in water pressurized with CO2. The size of the initial monomer droplets and of the resulting polymer particles can be varied by simply changing the CO2 pressure. Furthermore, at identical ethylene partial pressure, the polymerizations performed in the presence of CO2 are significantly faster than in its absence. Thus, the combination of CO2 and water is a promising green solvent to perform catalytic emulsion polymerizations.
