Introduction: This study examined romantic relationships among street-involved youth through the overlapping perspectives of resilience, attachment and social bonding. The main goal was to assess how youth understand their romantic attachment bonds as supporting or undermining resilience. While there are qualitative reports on how the social relationships of street-involved youth are linked to resilience, romantic relationships have yet to be differentiated with regard to resilience.

Parents' exposure to stressful ecosocial situations, like inadequate resources, is linked to parents' perceptions of infants' fussing and crying and less sensitive caregiving. However, studies supporting these findings predominantly come from Western contexts of parenting and infant care. Ecosocial situations may have different effects on parenting and infants in distinct cultural contexts. Read More

Secretion of the stress hormone cortisol follows a circadian rhythm and is stimulated following stress exposure. Cortisol regulates the transcription of several genes, primarily through activation of the glucocorticoid receptor (GR).

In the last decade, epigenetics has taken center stage to explain the relationships between stress exposure, health and behavior. Acquired or inherited epigenetic changes modulate gene expression states without modifying the DNA sequence itself, they can be long-lasting, yet, they are potentially reversible. Several studies have explored whether meditation-based interventions can influence gene expression profiles towards healthier directions, identifying candidate genes and biological pathways that seem to be sensitive to contemplative practices.

Alzheimer 's disease (AD) is characterized by progressive cognitive decline including memory impairment, cortical dysfunction, and neuropsychiatric disturbances. The drug discovery to treat AD consists to develop compounds able to act in multiple molecular targets involved in the pathogenesis of the disease and the repositioning of old drugs for new application. This way, the intracerebroventricular (icv) injection of streptozotocin (STZ) has been used as a metabolic model of sporadic AD. Read More

This paper aims to evaluate the effects of a product containing colloidal silver in the aquatic environment, using duckweed Lemna gibba as a model plant. Therefore, growth parameters, photosynthetic pigments content and protein content as physiological indices were evaluated. Changes in the content of non-enzymatic antioxidants and activity of several antioxidant enzymes, alongside with the accumulation of hydrogen peroxide and lipid peroxidation end-products were assessed to explore the potential of colloidal silver to induce oxidative stress.

Aims: The aim of this study is to determine the physical and functional interplay between fatty acid-binding protein 4 (FABP4) and its membrane receptor-like candidate protein, cytokeratin 1 (CK1), and to determine the effect of hindering CK1-mediated FABP4 cellular uptake on non-disturbed or metabolically stressed endothelial cells.
Methods: We monitored the direct interaction between FABP4 and CK1 using surface plasmon resonance, and the effects of blocking exogenous FABP4 (eFABP4) cellular uptake were determined by using specific siRNA to knock down the expression of CK1 in human umbilical vein endothelial cells (HUVECs). The expression and nuclear translocation of transcription factors involved in oxidative stress (NRF2) and inflammation (p65 subunit of NF-ĸB transcription factor) were determined by Western blotting analysis.

Cannabis is the most widely used illicit drugs and the changing legal, political and cultural climate will likely increase cannabis use further. One factor that may underlie the transition from recreational use to problematic use is stress. The hormone oxytocin (OXT) modulates stress and may have therapeutic efficacy for substance use disorders, but few studies have examined OXT in cannabis users. Read More

A number of pre-clinical studies have shown that brain-generated acetaldehyde, the first metabolite of ethanol, exerts reinforcing effects that promote the acquisition of ethanol intake, while chronic intake maintenance appears to be mediated by alcohol-induced brain neuroinflammation/oxidative stress. Recently, it was described that N-(1,3-benzodioxol-5-ylmethyl)-2,6-dichlorobenzamide (ALDA-1) activates aldehyde dehydrogenase-2 (ALDH2), enzyme that catalyzes the oxidation of ethanol-derived acetaldehyde to acetate. The aim of this study was to determine the effects of ALDA-1 on both the acquisition and the maintenance of alcohol intake in alcohol-preferring UChB rats. Read More

Background: A key mechanism thought to underlie Posttraumatic Stress Disorder (PTSD) is enhanced emotional memory consolidation. Recent evidence in healthy controls revealed that women have greater negative memory consolidation following stress relative to men. This study examined emotional memory consolidation in women and men with PTSD, and in trauma-exposed and non-trauma controls to test the hypothesis that emotionally negative memory consolidation would be greater in women with PTSD.

Nanoscale metallic glasses (MGs) are frequently used in experimental and computational studies to probe the deformation mechanisms in amorphous metals. Potential consequences of the significant surface to volume ratio in these extremely small materials, nevertheless, are not well understood. Here, using molecular dynamics simulations and novel selective 3D visualization, we show that significant irreversible atomic shear strain condenses on the 3D surface of these materials under low uniaxial stress, while the interior atoms are bearing much lower, mostly reversible shear strain.

Protein tyrosine (Tyr) nitration, the covalent addition of a nitro group (NO) to Tyr residues, is emerging as a candidate mechanism of endothelial dysfunction. Previous studies have shown that Tyr nitration is primarily induced by nitrosative stress, a process characterized by the production of reactive nitrogen species, especially peroxynitrite anion (ONOO), which is considered a secondary product of NO in the presence of superoxide radicals (O). However, the impact of nitrosative stress-induced Tyr nitration on endothelial dysfunction has not been thoroughly elucidated to date. Read More

As mechanisms controlling redox homeostasis become impaired with aging, exaggerated oxidant stress may cause disproportional oxidation of cell membranes and circulating phospholipids (PLs), leading to the formation of truncated oxidized PL products (Tr-OxPLs), which exhibit deleterious effects. This study investigated the role of elevated Tr-OxPLs as a factor exacerbating inflammation and lung barrier dysfunction in an animal model of aging. Mass spectrometry analysis of Tr-OxPL species in young (2-4 mo) and aging (18-24 mo) mice revealed elevated basal levels of several products [1-palmitoyl-2-(5-oxovaleroyl)- sn-glycero-phosphocholine (POVPC), 1-palmitoyl-2-glutaroyl- sn-glycero-phosphocholine, lysophosphocholine, 1-palmitoyl-2-(9-oxo-nonanoyl)- sn-glycero-3-phosphocholine, 1-palmitoyl-2-azelaoyl- sn-glycero-3-phosphocholine, O-1-O-palmitoyl-2-O-(5,8-dioxo-8-hydroxy-6-octenoyl)-l-glycero-3-phosphocholine, and others] in the aged lungs.

Using molecular dynamics simulations and electronic structure theory, we shed light on the charge dynamics that causes the differential interaction of tumor suppressor protein p53 with the p21 and Gadd45 genes in response to oxidative stress. We show that the sequence dependence of this selectivity results from competing charge transfer to the protein and through the DNA, with implications on the use of genome editing tools to influence the p53 regulatory function.

Myocardial revascularization in patients with stable ischemic heart disease aims at eliminating myocardial ischemia, in order to (i) relieve anginal symptoms; (ii) improve functional capacity; and, possibly, (iii) improve prognosis. Given that ischemic recurrences are relatively common in patients undergoing myocardial revascularization, an appropriate follow-up is needed as part of a secondary prevention program. Stress testing can be here useful to: (i) detect residual or recurrent ischemia/angina; (ii) define functional capacity in order to establish physical aerobic training individualized programs; (iii) stratify prognosis.
